vue.js select2 multiple select
|
<p>For many days I've searched to find an answer to this error. I tried many alternatives but nothing worked. </p>
<p>I need to select multiple values. When I select multiple values, my code hangs, but when I use a single select it works well with <code>self.$emit('input', this.value)</code>. What I need is to select multiple values.</p>
<p><strong>Select2.vue</strong></p>
<pre><code><template>
<select multiple class="input-sm" :name="name">

Querying and Filtering Array of JObjects with Linq
|
<p>I suppose this is another entry in my series of questions, but I'm stuck again. This time, I'm having trouble working with a JArray of JObjects and determining the Property.Value type for each element in the JArray... </p>
<p>My code is here:
<a href="https://dotnetfiddle.net/bRcSAQ" rel="nofollow">https://dotnetfiddle.net/bRcSAQ</a></p>
<p>The difference between my previous questions and this question is that my outer Linq query gets both JObject and JArray tokens, so that's why I have an <code>if (jo is JObject)</code> at Line 40 and a <code>if (jo is JArray)</code> at Line 48. </p>
<p>Once I know I have a JArray of <code><JObjects></code>, I have code that looks like this (Lines 48-):</p>
<pre><code> if (jo is JArray)
{
var items = jo.Children<JObject>();
// return a JObject object
}
</code></pre>
<p>When I use a debugger and look at items, I see that it contains 3 JObject objects--one for Item_3A1, Item_3A2, and Item3A3. But I need to know the JTokenType for each JProperty.Value because I am interested only in Property values of type JTokenType.String.</p>
<p>So I tried:</p>
<pre><code>// doesn't work :(
var items = jo.Children<JObject>()
.Where(p => p.Value.Type == JTokenType.String);
</code></pre>
<p>The compiler red-lines the Value property with the error <code>CS0119 'JToken.Value<T>(object)' is a method, which is not valid in the given context.</code></p>
<p>I realize that "p" in the Linq express is not a JProperty. I guess it's a JObject. And I don't know how to cast "p" so that I can examine the type of JProperty object it represents. </p>
<p>Ultimately, I need the code for JArray processing (starting at Line 48) to add an return a JObject that contains an JSON array composed only of JProperty objects of type JTokenType.String. This means that given the sample JSON, it first should return a JObject holding these JSON properties:</p>
<pre><code>{ ""Item_3A1"": ""Desc_3A1"" },
{ ""Item_3A2"": ""Desc_3A2"" },
{ ""Item_3A3"": ""Desc_3A3"" }
</code></pre>
<p>On the next iteration, it should return a JObject holding these JSON properties (notice that the nested Array3B1 properties are omitted because Array3B1 is not a JProperty with a Value type of JTokenType.String):</p>
<pre><code>{ ""Item_3B1"": ""Desc_3B1"" },
{ ""Item_3B2"": ""Desc_3B2"" },
</code></pre>
<p>The third iteration would contain:</p>
<pre><code>{ ""Item_3B11"": ""Desc_3B11"" },
{ ""Item_3B12"": ""Desc_3B12"" },
{ ""Item_3B13"": ""Desc_3B13"" }
</code></pre>
<p>And the fourth (final) iteration would contain:</p>
<pre><code>{ ""Item_3C1"": ""Desc_3C1"" },
{ ""Item_3C2"": ""Desc_3C2"" },
{ ""Item_3C3"": ""Desc_3C3"" }
</code></pre>
<p>This might be my final hurdle in this "series". </p>
<p>Sincere thanks to anyone who can and will help--and a special thanks again to users "Brian Rogers" and "dbc" for their truly amazing JSON.NET/Linq knowledge.</p>

android: device not supported by app- why?

getActivity() / context in a ViewHolder in Kotlin Android

Rake db:test:prepare task deleting data in development database
|
<p>Using a <a href="https://github.com/mhartl/sample_app_rails_3_2/blob/master/config/database.yml" rel="nofollow noreferrer">simple Rails sqlite3 configuration example</a> in my <strong>config/database.yml</strong> for a Rails 3.2.6 app, I used to reset my development database, re-seed it, and prepare my test database simply by performing:</p>
<pre><code>$ rake db:reset
$ rake db:test:prepare
</code></pre>
<p>After looking at <a href="https://web.archive.org/web/20120924203633/http://matthew.mceachen.us:80/blog/howto-test-your-rails-application-with-travis-ci-on-different-database-engines-1220.html" rel="nofollow noreferrer">this blog entry</a> about testing a Rails application with <a href="https://travis-ci.org/" rel="nofollow noreferrer">Travis CI</a> on different database engines, I thought I'd give it a try, so I installed mysql and postgresql using <a href="https://brew.sh/" rel="nofollow noreferrer">Homebrew</a> (I'm on OSX Snow Leopard), set them up as per the <code>brew info</code> instructions. I installed the relevant gems, and configured the database and Travis files as follows:</p>
<p><strong>Gemfile</strong></p>
<pre><code># ...
group :development, :test do
# ...
gem 'sqlite3', '1.3.6'
end
group :test do
# ...
# Test mysql on Travis CI
gem 'mysql2', '0.3.11'
end
group :test, :production do
# ...
# Test postgres on Travis CI and deploy on Heroku
gem 'pg', '0.13.2'
end
</code></pre>
<p><strong>config/database.yml</strong></p>
<pre><code>sqlite: &sqlite
adapter: sqlite3
database: db/<%= Rails.env %>.sqlite3
mysql: &mysql
adapter: mysql2
username: root
password:
database: my_app_<%= Rails.env %>

development:
<<: *defaults
test: &test
<<: *defaults

<<: *defaults
cucumber:
<<: *test
</code></pre>
<p><strong>.travis.yml</strong></p>
<pre><code>language: ruby
rvm:
- 1.9.2
- 1.9.3
env:
- DB=sqlite
- DB=mysql
- DB=postgresql
script:
- RAILS_ENV=test bundle exec rake --trace db:migrate
- bundle exec rake db:test:prepare
- bundle exec rspec spec/
before_script:
- mysql -e 'create database my_app_test'
- psql -c 'create database my_app_test' -U postgres
bundler_args: --binstubs=./bundler_stubs
</code></pre>
<p>Now, though, when I run <code>rake db:reset</code>, I get a <code>Couldn't drop db/development.sqlite3</code> error message before the development database is successfully created. So, it seems that there are now multiple calls being made to drop the same database(?). The traced output looks like:</p>
<pre><code>$ rake db:reset --trace
** Invoke db:reset (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:reset
** Invoke db:drop (first_time)
** Invoke db:load_config (first_time)
** Invoke rails_env (first_time)
** Execute rails_env
** Execute db:load_config
** Execute db:drop
Couldn't drop db/development.sqlite3 : #<Errno::ENOENT: No such file or directory - my_app/db/development.sqlite3>
** Invoke db:setup (first_time)
** Invoke db:schema:load_if_ruby (first_time)
** Invoke db:create (first_time)
** Invoke db:load_config
** Execute db:create
db/development.sqlite3 already exists
# ...
</code></pre>
<p>This is odd, but at least the development database gets created and seeded. The real issue comes when I run <code>rake db:test:prepare</code>: although there are no error messages, as well as the test database not being created, the data in the development database gets blown away (schema is still in tact, though). I tried directly specifying the Rails environment for the command and got:</p>
<pre><code>$ rake db:test:prepare RAILS_ENV=test
You have 7 pending migrations:
20120503193649 CreateUsers
# ...
Run `rake db:migrate` to update your database then try again.
</code></pre>
<p>After running <code>rake db:migrate RAILS_ENV=test</code>, I could run my rspec tests again. So, my rake commands to get the same results have now changed to:</p>
<pre><code>$ rake db:reset # (with an error)
$ rake db:migrate RAILS_ENV=test
</code></pre>
<p><em>If I change my</em> <strong>config/database.yml</strong> <em>file back to a simple sqlite3 only configuration,</em> <code>db:reset</code> <em>and</em> <code>db:test:prepare</code> <em>work as I expect.</em></p>
<p>So, does this mean that my mysql and/or postgres settings are causing rake tasks to repeat and/or they're messing with the Rails environment settings? Where should I be looking to confirm if my environment is really set up to work properly with these 3 database engines?</p>
<h3>Edit</h3>
<p>Looking at the <a href="https://weblog.rubyonrails.org/2012/8/3/ann-rails-3-2-8-rc2-has-been-released/" rel="nofollow noreferrer">release notes for Rails 3.2.8.rc2</a>, I found a change to <code>ActiveRecord</code> potentially related to this question:</p>
<ul>
<li>Do not set <code>RAILS_ENV</code> to <code>development</code> when using <code>db:test:prepare</code> and related rake tasks. This was causing the truncation of the development database data when using RSpec. In RC2 was fixed again when using <code>config.active_record.schema_format = :sql</code></li>
</ul>
<p><strong>config/application.rb</strong> has the following explanation:</p>
<pre><code># Use SQL instead of Active Record's schema dumper when creating the database.
# This is necessary if your schema can't be completely dumped by the schema dumper,
# like if you have constraints or database-specific column types
# config.active_record.schema_format = :sql
</code></pre>
<p>My schema doesn't have constraints or database-specific column types, so I didn't uncomment this line, however, given the content of the release note, I wagered that <code>RAILS_ENV</code> defaulting to <code>development</code> could be responsible for the deleted data in the development environment. So, I tried out a few things and got expected results by doing what I did before (after upgrading Rails to 3.2.8.rc2):</p>
<pre><code>$ rake db:reset # (with an error)
$ rake db:test:prepare RAILS_ENV=test # (with no "pending migrations" issue)
</code></pre>
<p>This is a bit better, but still seems wrong to me since there is still an error with <code>rake db:reset</code>, and it doesn't make sense to me to have to set <code>RAILS_ENV=test</code> when running a rake command specifically tailored for the test database.</p>
<h2>Update</h2>
<p>It would seem that upgrading to Rails 3.2.9 solves this issue due to the following fix:</p>
<ul>
<li>Fix bug where <code>rake db:test:prepare</code> tries to load the structure.sql into development database. Fixes #8032.</li>
</ul>
<p><em>Grace Liu + Rafael Mendonça França</em></p>
<p>I can now again reset my development database, re-seed it, and prepare my test database simply by performing:</p>
<pre><code>$ rake db:reset
$ rake db:test:prepare
</code></pre>

English to Morse Converter
|
<p>I've been working on a program that is supposed to convert english to morse code. I am having a really hard time dealing with the strings. For example I have no clue why I can have morseAlphabet have a set number of positions at [30] but I cannot do the same for latinAlphabet. Overall I have no clue how I am supposed to translate the words.</p>
<p>My idea was to see what character in the alphabet shows up in the first position of the phrase to be translated then print the corresponding alphabet position for the morse alphabet then move onto the second position in the phrase however me messing around with for loops just ended with me getting errors about for loops getting far too huge and memory errors or just gave me a blank.</p>
<p>With what I have right now whenever I enter the phrase to be translated it comes stops with a subscript out of range error and some of my earlier fiddling had it return jibberish(memory locations?) and I am really just out of ideas. I hope that this is phrased right and someone can help me because the past four hours of internet searches hasn't really helped me and to be honest at this point I am doubting if any of the stuff I've written is any use at all.</p>
<pre><code>#include <iostream>
#include <string>
int main()

int operatingMode = 0;
using namespace std;
std::string latinPhrase;

std::string morseAlphabet[30] = { ".-", "-...", "-.-.", "-..", ".", "..-.", "--.", "....", "..", ".---", "-.-", ".-..", "--", "-.", "---", ".--.", "--.-", ".-.", "...", "-", "..-", "...-", ".--", "-..-", "-.--", "--..", ".-.-.-", "--..--" };

How to Refresh Android List Adapter, so it shows new-added items
|
<p>I was working on a project. It's just showing a list of tasks and Adding new tasks to it. I have 3 CLASSES. One for adding, One for view and One to hold all information (or so I think).</p>
<p>I have 2 tasks in my List already, and they are shown properly. </p>
<p>The problem is, when I <strong>add</strong> a new task it won't show them in view. I have tried many possible solutions:</p>
<ul>
<li><p>simply adding item to list</p></li>
<li><p>creating a new list that consists items from old one and rebuilding adapter;</p></li>
<li><p>using <code>notifyDataSetChanged();</code> alongside with add() command;</p></li>
<li><p>etc.</p></li>

Fetch API and multer error while uploading file
|
<p>I'm trying to use fetch API to upload files to a node.js server (I'm using github's pollyfill if it has something to do with it: <a href="https://github.com/github/fetch" rel="noreferrer">https://github.com/github/fetch</a>).</p>
<p>The request is done like this:</p>
<pre><code>const data = new FormData();
data.append('file', file);
return fetch(this.concatToUrl(url), {
method: 'post',
headers: Object.assign({}, this.getHeaders(), {'Content-Type': 'multipart/form-data'}),
body: data,
});
</code></pre>
<p>On the server side I have, this declaration of route:</p>
<pre><code>app.post('/media', upload.single('file'), mediaRoutes.postMedia);
</code></pre>
<p>And trying to get the file like this:</p>
<pre><code>exports.postMedia = function(req, res) {
console.log('req.file', req.file, req.files, req.body);
return res.sendStatus(200);
}
</code></pre>
<p>But <code>req.file</code> is not being filled.</p>
<p>Also I'm getting this error from express side:</p>

Java Map sort by value
|
<p>I was looking for ways of sorting <code>Map<String, Integer></code> by values. I found <a href="https://stackoverflow.com/questions/109383/how-to-sort-a-mapkey-value-on-the-values-in-java">this post</a>, which solved my sorting problem, but not exactly. According to the post, I wrote the following code:</p>
<pre><code>import java.util.*;
public class Sort {
static class ValueComparator implements Comparator<String> {
Map<String, Integer> base;
ValueComparator(Map<String, Integer> base) {
this.base = base;
}
@Override
public int compare(String a, String b) {
if (base.get(a) >= base.get(b)) {
return 1;
} else {
return -1;
}
}
}
public static void main(String[] args) {
HashMap<String, Integer> map = new HashMap<String, Integer>();
ValueComparator vc = new ValueComparator(map);
TreeMap<String, Integer> sorted = new TreeMap<String, Integer>(vc);
map.put("A", 1);
map.put("B", 2);
sorted.putAll(map);
for (String key : sorted.keySet()) {
System.out.println(key + " : " + sorted.get(key)); // why null values here?
}
System.out.println(sorted.values()); // But we do have non-null values here!
}
}
</code></pre>
<p>Output:</p>
<pre><code>A : null
B : null
[1, 2]
BUILD SUCCESSFUL (total time: 0 seconds)
</code></pre>
<p>As you can see from the output, the <code>get</code> method always returns <code>null</code>. The reason is my <code>ValueComparator.compare()</code> method never returns <code>0</code>, which I've figured out by making <a href="https://stackoverflow.com/questions/13842830/treemapstring-integer-objects-get-method-return-null-value">this post</a>.</p>
<p>Someone suggested in that post the following to solve the <code>null</code> value problem:</p>
<pre><code> public int compare(String a, String b) {
if (base.get(a) > base.get(b)) {
return 1;
}else if(base.get(a) == base.get(b)){
return 0;
}
return -1;
}
</code></pre>
<p>I've tested this piece of code and it introduces a key merging problem. In other words, when the values are equal their corresponding keys are merged.</p>
<p>I've also tried the following:</p>
<pre><code> public int compare(String a, String b) {
if (a.equals(b)) return 0;
if (base.get(a) >= base.get(b)) {
return 1;
} else return -1;
}
</code></pre>
<p>It does not work either. Some of the values are still <code>null</code>. Besides, this workaround might potentially have logical problems.</p>
<p>Anyone can propose a fully working solution to my problem? I'd like the sort by value function to work and the <code>get</code> method to work at the same time.</p>

I Can't Find dompdf_config.inc.php or dompdf_config.custom.inc.php for setting "DOMPDF_UNICODE_ENABLED" true

<p>I use dompdf to save a html page as pdf by php.

Change < Formik > to useFormik
|
<p>I am using Formik/Yup for a validation of a page, which calls a GraphQL mutation. My code works fully:</p>
<pre><code>export default function RemoveUserPage() {
const [isSubmitted, setIsSubmitted] = useState(false);
const [isRemoved ,setIsRemoved] = useState(false);
const [errorMessage, setErrorMessage] = useState('');
const [removeUser] = useMutation(RemoveUserMutation);
function submitForm(email: string) {
setIsSubmitted(true);
removeUser({
variables: {
email: email,
},
}).then(({ data }: any) => {
setIsRemoved(true);
console.log('info: ', data.deleteUser);
})
.catch((error: { message: string; }) => {
setIsRemoved(false);
console.log("Error msg:" + error.message);
setErrorMessage(error.message)
})
}
return (
<div>
<PermanentDrawerLeft></PermanentDrawerLeft>
<Formik
initialValues={{ email: '' }}
onSubmit={(values, actions) => {
setTimeout(() => {
alert(JSON.stringify(values, null, 2));
actions.setSubmitting(false);
}, 1000);
}}
validationSchema={schema}
>
{props => {
const {
values: { email },
errors,
touched,
handleChange,
isValid,
setFieldTouched
} = props;
const change = (name: string, e: any) => {
e.persist();
handleChange(e);
setFieldTouched(name, true, false);
};
return (
<div className='main-content'>

</div>
</form>
<br></br>
{isSubmitted && StatusMessage(isRemoved, errorMessage)}
</div>
)
}}
</Formik>
</div>
);
}
</code></pre>
<p>However, now I want to use <code>useFormik</code> hook instead of <code><Formik></code> and I am unable to do so. I have seen the following example but I just can't figure out how exactly I could syntactically use it in my case since I am using material ui components instead of formic-specific inputs.</p>
<p><a href="https://jaredpalmer.com/formik/docs/api/useFormik" rel="nofollow noreferrer">https://jaredpalmer.com/formik/docs/api/useFormik</a></p>
<p>Edit:</p>
<p>This compiles and all but there's no validation happening on the textfields. What am I missing?</p>
<pre><code>export const schema = Yup.object({
email: Yup.string()
.email('Invalid Email')
.required('This Field is Required'),
});
export default function RemoveUserPage() {
const [isSubmitted, setIsSubmitted] = useState(false);

}
})
.catch((error: { message: string }) => {
setIsRemoved(false);
console.log('Error msg:' + error.message);
setErrorMessage(error.message);
});
};
const formik = useFormik({
initialValues:{ email: '' },
onSubmit:(values, actions) => {
setTimeout(() => {
alert(JSON.stringify(values, null, 2));
actions.setSubmitting(false);
}, 1000);
},

})
const handleChange = (e: ChangeEvent<HTMLInputElement>)=>{
const {name,value} = e.target;
formik.setFieldValue(name,value);
}
return (

<p>It gave me this error:</p>

<p>Secondly, earlier on, I was using <code>isValid</code>for the button but now it gives an error. Is there an alternative?</p>

JPA sequence generator not working

<p>Trying to setup an id with a JPA sequence generator:</p>
<pre><code>@Entity
@Table(name=CommitmentRegisterDetailTable.TABLE)
public class TestCrd {
@Id
@Column(name=CommitmentRegisterDetailTable.COMMIT_REG_DETAIL_ID)
@SequenceGenerator(name="CRD_ID", sequenceName="COMMIT_REG_DETAIL_ID_SEQ", allocationSize=1)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="CRD_ID")
private int id;
@Column(name=CommitmentRegisterDetailTable.COMMIT_REG_ID)
private int commitRegId = 89915;
}
</code></pre>
<p>With this entity I am able to do load, and merge. But when I do persist(), the SQL output shows it attempts to perform an INSERT with id = 0. Am I missing a step?</p>
<p>This is an Oracle DB.</p>
<p>Code where I persist:</p>
<pre><code> TestCrd testCrd = new TestCrd();
EntityManagerFactory factory = Persistence.createEntityManagerFactory( "incepPersistence" );
EntityManager em = factory.createEntityManager();
em.getTransaction().begin();
em.persist( testCrd );
em.getTransaction().commit();
em.close();
factory.close();
</code></pre>
<p>Sequence details:</p>
<pre><code>CREATED 07-JUN-16

</code></pre>
<h2>Background and some Investigations</h2>
<p>So first off, I'm not a Windows person so this is a brave new world for me. Having inherited a laptop from work that had a mad collection of libraries spread all over it I've managed to remove all previous installations of ruby and the Devkit and then installed the following:</p>
<ul>
<li>Ruby 1.9.3p484 with <a href="http://rubyinstaller.org" rel="noreferrer">Ruby Installer</a> into <code>C:/Ruby193</code></li>
<li>Ruby 2.0.0p353 with <a href="http://rubyinstaller.org" rel="noreferrer">Ruby Installer</a> into <code>C:/Ruby200</code></li>
<li>Devkit <code>DevKit-tdm-32-4.5.2-20111229-1559-sfx.exe</code> (for ruby 1x) extracted into <code>C:/Ruby193-devkit</code></li>
<li>Devkit <code>DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe</code> (32-bit for ruby 2x) extracted into <code>C:/Ruby200-devkit-x32</code>.</li>
</ul>
<p>I then installed <a href="https://github.com/vertiginous/pik" rel="noreferrer">Pik 0.2.8</a> as a gem and ran <code>pik_install</code> into a new directory <code>C:/bin</code> as per the installation instructions.</p>
<p>My PATH looks like this:</p>
<pre><code>PATH=C:\bin;C:\Ruby193\bin;C:\windows;C:\windows\system32;C:\windows\system32\Wbem;c:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\;c:\Program Files\Microsoft SQL Server\100\Tools\Binn\;c:\Program Files\Microsoft SQL Server\100\DTS\Binn\;C:\Program Files (x86)\Common Files\Roxio Shared\DLLShared\;C:\Program Files\Java\jdk1.6.0_33\bin;C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\;C:\Program Files (x86)\Common Files\Apple\Apple Application Support;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files\TortoiseSVN\bin;C:/inpath;C:\Program Files (x86)\WinMerge;C:\ChromeDriver;C:\Program Files\WIDCOMM\Bluetooth Software\;C:\Program Files\WIDCOMM\Bluetooth Software\syswow64
</code></pre>
<p>The important things being that <code>C:/bin</code> and <code>C:/Ruby193/bin</code> are in the path. This means that ruby 1.9.3 is loaded by default when I fire up a shell and I can successfully switch to 2.0.0 with <code>pik use 2.0.0p353</code>. In other words, pik works fine.</p>
<p>Devkit <a href="https://github.com/oneclick/rubyinstaller/wiki/Development-Kit" rel="noreferrer">is intended</a> to allow the compiling of native C/C++ binaries from gems on Windows, so as to aviod using precompiled windows binaries.</p>
<p>Because I've got two versions of ruby installed, and each requires a different devkit (one for 2x and one for 1x), I had to do the setup for devkit twice:</p>
<pre><code>cd C:/Ruby193-devkit
ruby dk.rb init
# Edit config.yml to remove all but Ruby193
ruby dk.rb install
cd C:/Ruby200-devkit
ruby dk.rb init
# Edit config.yml to remove all but C:/Ruby200
ruby dk.rb install
</code></pre>
<p>At this point I should have been able to run <code>gem install json —platform=ruby</code> successfully, but got the error above. After a little digging <a href="https://github.com/oneclick/rubyinstaller/wiki/Troubleshooting#wiki-gems_fails_comspec_autorun" rel="noreferrer">I discovered this</a>, which advises checking that COMSPEC is set corectly and removing any AutoRun keys from <code>HKEY_CURRENT_USER\Software\Microsoft\Command Processor</code> – I had one from ANSIcon and duly deleted it.</p>
<p>Unfortunatly I was still unable to install the json gem.</p>
<p>It then struck me that perhaps the wrong version of GCC was being used, or not being found. The two versions of Devkit come with different versions of gcc:</p>
<pre><code>> C:\Ruby193-devkit\mingw\bin\gcc —version
gcc (tdm-1) 4.5.2
> C:\Ruby200-devkit-x32\mingw\bin\gcc —version
gcc (rubenv-4.7.2-release) 4.7.2
</code></pre>
<p>I then wondered if pik wasn't loading the version of devtools (and therefore gcc) for the specific version of ruby that i'd picked, and was always using 1.9.3. Thanks to <a href="http://rubyonwindowsguides.github.io/book/ch02-04.html" rel="noreferrer">this article</a>, it seems that's not the case:</p>
<pre><code>> pik use 193
> where ruby

> cat C:\Ruby193\lib\ruby\site_ruby\devkit.rb
# enable RubyInstaller DevKit usage as a vendorable helper library
unless ENV['PATH'].include?('C:\\Ruby193-devkit\\mingw\\bin') then
puts 'Temporarily enhancing PATH to include DevKit...'
ENV['PATH'] = 'C:\\Ruby193-devkit\\bin;C:\\Ruby193-devkit\\mingw\\bin;' + ENV['PATH']
end
ENV['RI_DEVKIT'] = 'C:\\Ruby193-devkit'
ENV['CC'] = 'gcc'
ENV['CXX'] = 'g++'
ENV['CPP'] = 'cpp'
> pik use 200
> where ruby
C:\Ruby200\bin\ruby.exe
> cat C:\Ruby200\lib\ruby\site_ruby\devkit.rb
# enable RubyInstaller DevKit usage as a vendorable helper library
unless ENV['PATH'].include?('C:\\Ruby200-devkit-x32\\mingw\\bin') then
phrase = 'Temporarily enhancing PATH to include DevKit...'
if defined?(Gem)
Gem.ui.say(phrase) if Gem.configuration.verbose
else
puts phrase
end
puts "Prepending ENV['PATH'] to include DevKit..." if $DEBUG
ENV['PATH'] = 'C:\\Ruby200-devkit-x32\\bin;C:\\Ruby200-devkit-x32\\mingw\\bin;' + ENV['PATH']
end
ENV['RI_DEVKIT'] = 'C:\\Ruby200-devkit-x32'
ENV['CC'] = 'gcc'
ENV['CXX'] = 'g++'
ENV['CPP'] = 'cpp'
</code></pre>
<p>(I don't actually have cat available on windows but it makes for a clearer explanation)</p>
<p>As you can see, it looks like the correct version of devkit is being added to the path by devkit.rb, which is obviously being loaded because my error contains 'Temporarily enhancing PATH to include DevKit…'.</p>
<h2>Back to the original error</h2>
<p>It was:</p>
<pre><code>The system cannot find the path specified.

The system cannot find the path specified.

<p>Unfortunatly the results log doesn't exactly offer much in the way of help. This is what gem_make.out looks like:</p>
<pre><code>C:/Ruby193/bin/ruby.exe extconf.rb

</code></pre>
<p>I thought that <code>extconf.rb</code> might offer some help, but I can't make head nor tail of it:</p>
<pre><code>require 'mkmf'
unless $CFLAGS.gsub!(/ -O[\dsz]?/, ' -O3')
$CFLAGS << ' -O3'
end
if CONFIG['CC'] =~ /gcc/

$CFLAGS << ' -O0 -ggdb'
end
end

<p>The Makefile in <code>C:/Ruby193/lib/ruby/gems/1.9.1/gems/json-1.8.1/ext/json/ext/generator</code> <a href="https://gist.github.com/dannysmith/8043321" rel="noreferrer">looks like this</a>. It seems odd to me that this Makefile is even being created.</p>
<p>If anybody with a bit more Windows/Ruby experience can shed any light on this it would be amazing!</p>
<p>PS. I'm on Windows 7 Professional SP1</p>
<h2>Update after some more digging</h2>
<p>So I wanted to check that devkit was defiantly enhancing the path with the correct devkit directories. Thanks to a suggestion from another SO question, I moved the devkit installations inside the Ruby directories:</p>
<p>The tdm devkit now lives in <code>C:\Ruby193\devkit</code> while the mingw64 lives in <code>C:\Ruby200\devkit</code>. Having run <code>ruby dk.rb install -f</code> for each devkit, I opened up both devkit.rb files to check that the path's had been updated correctly. They had, and I updated the puts so it should print "Temporarily enhancing PATH do include DevKit for 1.9" or "Temporarily enhancing PATH do include DevKit for 2". By way of confirmation that the correct devkit is being loaded:</p>
<pre><code>C:\>pik 193

<p>This clearly tells us two things:</p>
<ol>
<li>Some other devkit.rb file is being loaded when I'm using ruby 1.9, as the 'for 1.9' message isn't being printed.</li>
<li>This is unlikely to be the actual problem, as the error is identical in either case.</li>
</ol>
<p>I'm going to see if I can build manually using the generated Makefiles.</p>

Force each row in Bootstrap table to be a one-liner when table is wider than screen
|
<p>I am building up a dynamic table which consists of 1-50 columns depending what the user selects. When the user selects 1-6 colums there is no problem showing all the data on the screen but when the user selects more than 6 columns the table tries to squeeze the view together on the screen resulting in each row being expanded to multiple lines.</p>
<p>I want it to always show the text in one line as this (OK):
<a href="https://i.stack.imgur.com/XWAFp.png" rel="noreferrer"><img src="https://i.stack.imgur.com/XWAFp.png" alt="OK"></a></p>
<p>But having many columns will wrap the text in to two or more lines (not OK):
<a href="https://i.stack.imgur.com/F8skR.png" rel="noreferrer"><img src="https://i.stack.imgur.com/F8skR.png" alt="Not OK"></a></p>
<p>The column width is not defined as it also varies depending on the text to show.</p>
<p>How can I make sure the row will always be a one-liner like ex.1 no matter how many columns the user selects?</p>
<p>I have this <a href="http://jsfiddle.net/wNPBp/1/" rel="noreferrer">JSFiddle demo</a> with the code for the two above examples:</p>
<pre><code><table class='table'>
<thead>

Prevent resubmit form after click "back" button
|
<p>I have 2 pages :<br/><br/>
<strong>page1.php :</strong><br/>
- has a form with text box and a "submit" button. Eg : <code><form name="frm_register" action="page1.php" method="post"></code><br/><br/>
- php and mysql code to store the value of textbox to database. Javascript will redirect the page to <code>php2.php</code> after the value is submitted to database. Eg : </p>
<pre><code>$query = "INSERT INTO traceuser (username) VALUES ('{$username}')";
$result = mysql_query($query, $connection);
echo '<script language="javascript">window.location="page2.php";</script>';
</code></pre>
<p><strong>page2.php</strong><br/>
- mysql retrieve the data from database and display on this page.<br/></p>
<p><strong>Problem :</strong> When I press "back" button, the browser will pop up a warning message saying that the form will be resubmit. How to prevent resubmit the form when click "back" button? Is it I need to clear the cache of page1.php? How to do it with php or javascript or ajax?</p>
<p><hr>
<strong>Update 1 :</strong> Thanks for the answer of replacing javascript <code>window.location="page2.php"</code> to php <code>header('Location: home2.php');</code>. It fix 80% of problem. The rest of 20% problem show below :</p>
<pre><code> if (strtotime($_SESSION['servertime']) < time()-3){ //10800 = 3 hours 3600 = 1 hour
if (($username != "") AND ($username != $_SESSION[username])){
$_SESSION['servertime'] = $servertime;
$_SESSION['username'] = $username;
$query = "INSERT INTO traceuser (username) VALUES ('{$username}')";
$result = mysql_query($query20, $connection);
header('Location: page2.php');
exit;
} else {
echo "same name"; //problem here
}
}else{
echo "submit multiple data too fast"; //problem here too.
}
}
</code></pre>
<p>The problem happen when do the following steps :<br/>
1) User submit data successfully, jump to page2.php view records.<br/>
2) User click "back" button, jump back to page1.php.<br/>
3) User submit data fail, stay on page1.php. (because too fast or same name)<br/>
4) User submit data successful, jump to page2.php view records.<br/>
5) User click "back" button, but browser shows warning message "form will be resubmited".<br/></p>
<p>The problem is because of Step 3. Step 3 didn't run <code>header('Location: page2.php');</code>, didn't jump to page2.php. So it cause Step 5 show the warning message. How to fix this problem?
<hr>
<strong>Update 2 :</strong> I have figured out the solution to fix the 20% problem, it works perfectly. I use <code>session['error123']</code> to decide whether or not want to display the error message "same name". I kill <code>session['error123']</code> if success submit data to database or if success jump to page2.php. I also use <code>header('Location: page1.php');</code> to redirect to own page (same page) to make the page forget about form submission previously. Example of codes :</p>
<pre><code>if ($_SESSION['error123'] == "toofast"){
echo $_SESSION['error123'] ;
}elseif ($_SESSION['error123'] == "samename"){
echo $_SESSION['error123'] ;
}
if (strtotime($_SESSION['servertime']) < time()-3){ //10800 = 3 hours 3600 = 1 hour
if (($username != "") AND ($username != $_SESSION['username'])){
$_SESSION['username'] = $username;
$query = "INSERT INTO traceuser (username) VALUES ('{$username}')";
$result = mysql_query($query20, $connection);
$_SESSION['error123'] = "aa";
header('Location: http://localhost/plekz/page2.php');
exit;
} else {
$_SESSION['error123'] = "samename";
header('Location: http://localhost/plekz/page1.php');
exit;
}
}else{
$_SESSION['error123'] = "toofast";
header('Location: http://localhost/plekz/page1.php');
exit;
}
}
}
</code></pre>
<p>Note : You need to buffer the output by <code><?php ob_start();?></code> because $_SESSION cannot put before header(). Buffer will stop all output including session, let header() send the output first.</p>

Parsing error "parserOptions.project" has been set for @typescript-eslint/parser

<p>I created a new <a href="https://docs.nestjs.com/" rel="noreferrer">NestJS project</a> which is a very popular NodeJS framework. But I have this error (see title) on my IDE (PhpStorm 2020.2-Beta) and ESLint doesn't work at all.</p>

Renaming an uploaded file using Multer doesn't work (Express.js)
|
<p>I'm trying to upload a file from a HTML form using Express.js and Multer. I've managed to save the file to the desired location (a folder named <em>uploads</em>).</p>
<p>However, I'd like to rename the file while uploading it because, by default, Multer gives it a strange name such as:</p>
<blockquote>
<p>5257ee6b035926ca99923297c224a1bb</p>
</blockquote>
<p>Might be a hexadecimal time stamp or so but I need a more explicit name in order to call a script on it later.</p>
<p>I've followed the explanation found <a href="https://stackoverflow.com/questions/29214237/rename-a-file-with-multer-is-not-working">here</a> but it doesn't do anything more than it used to: uploading the file with the hexa name.</p>
<p>Also, the two events <strong>onFileUploadStart</strong> and <strong>onFileUploadComplete</strong> never seem to be triggered as I don't get anything logged in my console.</p>
<p>I am using two separate files for the server and the routing:</p>
<p><strong><em>app.js</em></strong></p>

coverage.py does not cover script if py.test executes it from another directory
|
<p>I got a python script which takes command line arguments, working with some files.
I'm writing succeeding tests with <code>py.test</code> putting this script through its paces, executing it with <code>subprocess.call</code>.</p>
<p>Now I want to analyze code coverage with <code>coverage.py</code>.
Coverage, when used via the <code>pytest-cov</code> plugin (which has subprocess-handling built-in), <strong>does not see/cover my script</strong> when it is called from a temporary testing directory created with <code>py.test</code>'s <code>tmpdir</code> fixture.
Coverage <strong>does see</strong> my script when it's called in the directory it resides in (and the filename argument points to a remote path).</p>
<p>In both situations, my <strong>tests pass</strong>! Coverage 3.6, pytest-2.3.5, pytest-cov 1.6, all from PyPi.</p>
<p>Question: How can I get coverage to recognize my script even if it's executed in another directory? Is this a bug in coverage, or something which is just not possible to do? Would be surprised if the latter, after all, <code>tmpdir</code> is a stock mechanism of py.test...</p>
<p><strong>Minimal example:</strong></p>
<p>I got a script <code>my_script.py</code> which just echoes the contents of a file <code>arg_file.txt</code> supplied via command-line argument. In two different tests, this is once called in a <code>tmpdir</code>, and once in the script's location. Both tests pass, but the in the tmpdir test, I get no coverage information! </p>

<p><strong>Edit:</strong> Interstingly, when running the coverage tests with <code>-s</code>, too, there's more curious output - coverage warns that <code>No data was collected</code>, when obviously it was collected, and in the <code>tmpdir</code> test warns that <code>Module my_script.py was never imported.</code>??</p>

ClassNotFoundException upon running JAR, no errors while running in IntelliJ IDEA
|
<p>I'm just starting to build Java apps (I do have .NET experience) and I was trying to build a small test app whose whole code is this :</p>
<pre><code>package com.company;
import com.microsoft.sqlserver.jdbc.SQLServerDataSource;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
public class Main {
public static void main(String[] args) throws SQLException {
System.out.println("Buna lume!");
SQLServerDataSource ds = new SQLServerDataSource();
ds.setIntegratedSecurity(true);
ds.setServerName("localhost");
ds.setPortNumber(1433);
ds.setDatabaseName("Test");
Connection con = ds.getConnection();
String SQL = "SELECT * FROM Test WHERE ID = ?";
PreparedStatement stmt = con.prepareStatement(SQL);
stmt.setInt(1, 2);
ResultSet rs = stmt.executeQuery();
while (rs.next()) {
System.out.println(rs.getInt(1) + ", " + rs.getString(2));
}
rs.close();
stmt.close();
con.close();
}
}
</code></pre>
<p>If I run the app in the IDE (IntelliJ IDEA 12.1.6 Community Edition), having the SQL Server available, the app runs fine doing exactly what it should.</p>
<p>The SQL Server Driver is downloaded from Microsoft and added as an External Library. I have created an artifact as JAR file :</p>
<p><img src="https://i.stack.imgur.com/OJFn4.png" alt="enter image description here"></p>
<p>Now, if I include the sqljdbc4.jar in the cliTest.jar (my JAR) the resulted JAR is fat (550kB and includes the classes in that JAR too). Or I can exclude it. Either way, running</p>
<pre><code>java -jar cliTest.jar
</code></pre>
<p>Results in </p>
<pre><code>Buna lume!

<p>I bet I'm missing something quite basic but I just can't figure out what exactly is causing this.</p>
<p>LE1 : I tried adding sqljdbc4.jar (although it didn't seem necessary) and sqljdbc_auth.dll in the directory containing the JAR but still no change.</p>
<p>Later edit 2 : Based on Nikolay's answer I've done the following :</p>
<ol>
<li>Deleted the existing artifact</li>
<li>Created a new artifact like so :</li>
</ol>
<p><img src="https://i.stack.imgur.com/FJIAn.png" alt="enter image description here"></p>
<p><img src="https://i.stack.imgur.com/nw70Z.png" alt="enter image description here"></p>
<p>.. and resulted this :</p>

<li><p>CMD Prompt at the folder containing :</p></li>

"Cannot call value of non-function type"
|
<p>I have just downloaded the Xcode 8 Beta so that I can include some of the new iOS 10 frameworks in my app. However, during the process of converting my code from Swift 2 to Swift 3, I ran into several errors. I fixed all but one super annoying one. </p>
<p>I am getting the error:</p>
<blockquote>
<p>Cannot call value of non-function type 'JSQMessagesCollectionView!' at the following line of code:</p>
</blockquote>
<pre><code>let cell = super.collectionView(collectionView, cellForItemAtIndexPath: indexPath) as! JSQMessagesCollectionViewCell
</code></pre>
<p>Here is my entire function for context:</p>
<pre><code>func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell{
let cell = super.collectionView(collectionView, cellForItemAtIndexPath: indexPath) as! JSQMessagesCollectionViewCell
let message = messages[indexPath.item]
if message.senderId == senderId {
cell.textView!.textColor = UIColor.whiteColor()
} else {
cell.textView!.textColor = UIColor.blackColor()
}
return cell

Correct YUV422 to RGB conversion
|
<p>I've been trying to tackle a YUV422 into a RGB conversion problem for about a week. I've visited many different websites and have gotten different formulas from each one. If anyone else has any suggestions I would be glad to hear about them. The formulas below give me an image with either and overall purple or a green hue in them. As of this moment I haven't been able to find a formula that allows me to get back a proper RGB image. I have include all my various chunks of code below.</p>

Setting Up ActiveMQ
|
<p>I have followed a tutorial to install ActiveMQ <a href="http://servicebus.blogspot.com/2011/02/installing-apache-active-mq-on-ubuntu.html">http://servicebus.blogspot.com/2011/02/installing-apache-active-mq-on-ubuntu.html</a></p>
<p>I dont quite understand this part of the tutorial</p>
<pre><code>Now, you must create the data/jmx.password and data/jmx.access files
</code></pre>
<p>How should I work this out?</p>
<p>I tried running the service by</p>
<pre><code>sudo /etc/init.d/activemq start
</code></pre>
<p>and I get this response</p>
<pre><code>INFO: Loading '/etc/default/activemq'

<p>but I'm still unable to connect to </p>

<p>Thanks in advance.</p>
<p>I also tried <code>sudo apt-get install activemq</code> then</p>
<pre><code>activemq

<p>which gave me </p>

Tasks provided by the sysv init script:
restart - stop running instance (if there is one), start new instance
console - start broker in foreground, useful for debugging purposes
status - check if activemq process is running
setup - create the specified configuration file for this init script
(see next usage section)
Configuration of this script:
The configuration of this script can be placed on /etc/default/activemq or /home/iandjx/.activemqrc.
To use additional configurations for running multiple instances on the same operating system
rename or symlink script to a name matching to activemq-instance-<INSTANCENAME>.
This changes the configuration location to /etc/default/activemq-instance-<INSTANCENAME> and
$HOME/.activemqrc-instance-<INSTANCENAME>. Configuration files in /etc have higher precedence.

Display point style on legend in chart.js

<p><a href="https://jsfiddle.net/43Tesseracts/qmhhc089/" rel="nofollow noreferrer">https://jsfiddle.net/43Tesseracts/qmhhc089/</a></p>
<p>For this chart's first dataset <code>XPData</code>, how do I set the legend style to use the point instead of the line?</p>

Angular: Cannot Get /
|
<p>I am trying to open, build and run someone else's Angular 4 project but I am not able to view the project when I run it my way. I don't see what is going wrong or what I should do now. I already had everything in place to use NPM and NodeJS</p>
<p>The steps I took were:</p>
<ul>
<li>Open up the project</li>
<li>npm install</li>
<li>ng serve</li>
</ul>
<p>The project compiles the right way. (I have an own Angular app and I know how this looks like) The console is showing: </p>
<blockquote>
<p>'** NG Live Development Server is listening on localhost:4200, open your browser on <a href="http://localhost:4200" rel="noreferrer">http://localhost:4200</a> **'.</p>
</blockquote>
<p>Then, when I opened up a web browser, I navigated to localhost:4200 and a web page with the following text were shown: </p>
<blockquote>
<p>'Cannot GET /'</p>
</blockquote>
<p>And on the console was the following text:</p>
<blockquote>
<p>'GET <a href="http://localhost:4200/" rel="noreferrer">http://localhost:4200/</a> 404 (Not Found)'</p>
</blockquote>
<p>The project should work fine but I am not able to navigate to a working URL on the web page. Routing is set-up another way as I am used to doing this. In app.module.ts the following is implemented:</p>
<p>app.module.ts</p>
<pre><code>const appRoutes: Routes = [
{ path: '', redirectTo: 'tree', pathMatch: 'full' },
{ path: 'admin', component: AdminPanelComponent, canActivate: [AuthGuard],
children: [{path:'', component: PanelComponent},{path: 'add', component:
AddTreeComponent}, {path:'manage-trees', component:ManageTreesComponent},
{path:'manage-users', component: ManageUsersComponent}, {path:'view-trees',
component: ViewTreeComponent}]},
{path:'tree', component: TreeComponent},
{path:'error', component: ErrorComponent},
{path:'unauthorized', component: UnauthorizedComponent},
{path:'login', component: LoginComponent},
{path:'entire-tree', component: EntireTreeComponent},
{ path: '**', component: PageNotFoundComponent },
];
</code></pre>
<p>Also opening up a web page like; localhost:4200/tree does not work. When I let angular stop serving the web page, the web page displays: "this site can't be reached'. So I think there is running something at localhost:4200... Also, another project of this person behaves the same way.</p>
<p><a href="https://i.stack.imgur.com/PKZlU.png" rel="noreferrer"><img src="https://i.stack.imgur.com/PKZlU.png" alt="enter image description here"></a></p>
<p>Does anybody know what is going on? </p>

<p>After I ran <code>npm install -g angular-cli</code> I wasn't able to run <code>ng serve</code>. (You have to be inside an angular-cli project in order to use the build command after reinstall of angular-cli)</p>
<p>Then I ran <code>npm install -g @angular/cli@latest</code> and I was able to use <code>ng serve</code> again. </p>
<p><strong>OBSERVATION 2:</strong></p>
<p>After building the app with: 'ng build ...' there is no index.html in the 'dist' folder... When I set the website online, there is just a folder structure instead of a nice website. I think that's because there is no index.html.</p>

Facebook Javascript SDK error "Object [object Object] has no method 'init`
|
<p>One of the first things that needs to be done in order to load the SDK for interacting with Facebook, is to run:</p>
<p><code>FB.init(params)</code></p>
<blockquote>
<p>This method is used to initialize and setup the SDK. . . . . .
All other SDK methods must be called after this one, because they
won't exist until you do.</p>
</blockquote>
<p><a href="https://developers.facebook.com/docs/javascript/reference/FB.init/" rel="nofollow">Facebook JavaScript SDK: .init()</a></p>
<p>I'm getting the error msg:</p>
<p><code>Object [object Object] has no method "init"</code></p>
<p>I'm not getting an error that <code>FB</code> is undefined, so I'm assuming that at least part of the <code>Facebook Javascript SDK</code> loaded.</p>
<p>When the <code>SDK</code> loads, Facebook puts contents into a <code><div></code> element: <code><div id="fb-root"></div></code></p>
<p>Just for the fun of it, I used <code>.innerHTML</code> to see if I could extract anything out of that <code><div></code>.</p>
<pre><code>var fbRootContent = document.getElementById('fb-root').innerHTML;
console.log("fbRoot Content: " + fbRootContent);
</code></pre>
<p>And it does show that something got injected into that <code><div></code>. So, . . . I'm assuming that at least some of the <code>Facebook Javascript SDK</code> loaded.</p>
<p>One possible issue, is that I'm using Google Apps Script, and lots of content gets sanitized and stripped out before it is served. So it's a possibility that, even though some of the SDK is loading, some of it is getting stripped out by the sanitation process.</p>
<p>I'm simply trying to determine if it's possible to load the <code>Facebook Javascript SDK</code> into Apps Script. I haven't had any luck so far. Here is the latest code I've used in the attempt to test whether the SDK can be loaded or not.</p>
<pre><code><div id="fb-root"></div>

<p>Note that I am not loading the SDK asynchronously. I'm doing that on purpose to test if it will load or not. Note the line:</p>
<pre><code><script src="https://connect.facebook.net/en_US/all.js"></script>
</code></pre>
<p>Facebook suggests loading the SDK a different way. Why? Because it might slow down the initial load of your app.</p>
<p>So, why am I getting the error: <code>Object [object Object] has no method "init"</code></p>
<p>And is it possible to load the <code>Facebook Javascript SDK</code> into Google Apps Script?</p>
<p>I'm using jQuery: <code>$(document).ready</code>, </p>
<p><a href="http://learn.jquery.com/using-jquery-core/document-ready/" rel="nofollow">jQuery $(document).ready()</a></p>
<p>so <code>FB.init</code> shouldn't be getting called until the <code><script></code> tag has loaded the Facebook SDK.</p>

Sorting in pyqt tablewidget

<p>How can I sort a coloumn in pyqt by the highest number? Currently I have <code>setSortingEnabled(True)</code> and that only sorts it by the most numbers (ex. 1,1,1,1,2,2,2,3,3) i want to do it by the highest number for example (ex. 58,25,15,10). Thanks!</p>

VB.net Simple Multithreading

<p>I have a Private Sub Fill(), which im trying to call from button1, in the form of </p>
<pre><code>Dim t1 As System.Threading.Thread = New System.Threading.Thread(AddressOf Me.Fill)

<p>However, when I run the program nothing happens. I click the button numerous times and the function isnt being executed. What gives? The Fill function is basically a outputting bunch of html from IE into a textbox, running regex and outputting the results in a listbox.</p>
<p>Can anyone help me get this working? I'd appreciate the help.
<strong>EDIT:</strong> Below, is the Fill function that I am trying to get working. The function itself works, when i try it without multithreading. But not with it...</p>

How to make an asynchronous Dart call synchronous?
|
<p>I'm on the way to evaluate Dart for a German company by porting various Java programs to Dart and compare and analyze the results. In the browser Dart wins hands down. For server software performance seemed to be a serious isssue (see <a href="https://stackoverflow.com/questions/28026648/how-to-improve-dart-performance-of-data-conversion-to-from-binary">this question of me</a>) but that got mostly defused.</p>
<p>Now I'm in the area of porting some "simple" command-line tools where I did not expect any serious problems at all but there is at least one. Some of the tools do make HTTP requests to collect some data and the stand-alone Dart virtual machine only supports them in an asynchronous fashion. Looking through all I could find it does not seem to be possible to use any asynchronous call in a mostly synchronous software.</p>
<p>I understand that I could restructure the available synchronous software into an asynchronous one. But this would transform a well-designed piece of software into something less readable and more difficult to debug and maintain. For some software pieces this just does not make sense.
My question: Is there an (overlooked by me) way to embed an asynchronous call into a synchronously called method?</p>
<p>I imagine that it would not be to difficult to provide a system call, usable only from within the main thread, which just transfers the execution to the whole list of queued asynchronous function calls (without having to end the main thread first) and as soon as the last one got executed returns and continues the main thread.</p>
<p>Something which might look like this:</p>
<pre class="lang-dart prettyprint-override"><code>var synchFunction() {
var result;
asyncFunction().then(() { result = ...; });
resync(); // the system call to move to and wait out all async execution
return result;
}
</code></pre>
<p>Having such a method would simplify the lib APIs as well. Most "sync" calls could be removed because the re-synchronisation call would do the job. It seems to be such a logical idea that I still think it somehow exists and I have missed it. Or is there a serious reason why that would not work?
<hr>
After thinking about the received answer from <code>lm</code> (see below) for two days I still do not understand why the encapsulation of an asynchronous Dart call into a synchronous one should not be possible. It is done in the "normal" synchronous programing world all the time. Usually you can wait for a resynchronization by either getting a "Done" from the asynchronous routine or if something fails continue after a timeout.</p>
<p>With that in mind my first proposal could be enhanced like that:
</p>
<pre class="lang-dart prettyprint-override"><code>var synchFunction() {
var result;
asyncFunction()
.then(() { result = ...; })
.whenComplete(() { continueResync() }); // the "Done" message
resync(timeout); // waiting with a timeout as maximum limit
// Either we arrive here with the [result] filled in or a with a [TimeoutException].
return result;
}
</code></pre>
<p>The <code>resync()</code> does the same that would normally happen after ending the <code>main</code> method of an isolate, it starts executing the queued asynchronous functions (or waits for events to make them executable). As soon as it encounters a <code>continueResync()</code> call a flag is set which stops this asynchronous execution and <code>resync()</code> returns to the main thread. If no <code>continueResync()</code> call is encountered during the given <code>timeout</code> period it too aborts the asynchronous execution and leaves <code>resync()</code> with a <code>TimeoutException</code>.</p>
<p>For some groups of software which benefit from straight synchronous programing (not the client software and not the server software) such a feature would solve lots of problems for the programer who has to deal with asynchrounous-only libraries.</p>
<p>I believe that I have also found a solution for the main argument in <code>lm</code>'s argumentation below. Therefore my question still stands with respect to this "enhanced" solution which I proposed: <strong>Is there anything which really makes it impossible to implement that in Dart?</strong></p>

path fill color in d3
|
<p>Good day,</p>
<p>Coder, I am new to d3 and json. i want to create a simple map projection that will identify the population of each country that was saved in csv file. </p>
<p>I already created the map projection and now i am stock for almost a week on how to fill the country based on the population on my csv file..</p>
<p>In that code below it can identified the highest or lowest population of the world by using the circle, but i dont like to use circle simply because it can overlap each other, all i want is to fill the country either green,blue or red red being the highest and green being the lowest. </p>
<p>here is my sample csv file</p>
<p>country, population,lat, lon
PHILIPPINES,10, 13, 122
CANADA, 2000, 60, -95
JAPAN, 500, 36, 138

<p>As far as I can tell, on Android the app never tries an upload.
My server runs <code>express</code> and has the <code>cors</code> middleware enabled with the default configuration</p>
<pre><code>{
"origin": "*",
"methods": "GET,HEAD,PUT,PATCH,POST,DELETE",
"preflightContinue": false,
"optionsSuccessStatus": 204
}
</code></pre>
<p>Any ideas what to do here? I get the feeling that the Android is baulking at the "*" origin, but have no idea what to put in place for a mobile app.</p>
<p>Or am I barking up the wrong tree completely?</p>

Nice inset border in CSS3
|
<p>I'm really loving this border style I've seen around on the tubes lately:</p>
<p><img src="https://i.stack.imgur.com/Fl8af.png" alt="enter image description here"></p>
<p>It'll probably look better if you just view it on the site: <a href="http://markdotto.com/bootstrap/" rel="nofollow noreferrer">http://markdotto.com/bootstrap/</a></p>
<p>I'm particularly interested in how they're creating this effect, it seems that the bottom border is highlighted while the top is darkened. I know how I'd do this in Photoshop, but how are they doing it in CSS? </p>

Android Set Text of TextView in Fragment that is in FragmentPagerAdapter
|
<p>This one is driving me nuts. Basically, I want to create a <code>ViewPager</code> and add a few <code>Fragment</code>s to it. Then, all I want to do, it set a value in one of the <code>Fragment</code>'s <code>TextView</code>s. I can add the <code>Fragment</code>s fine, and they attach, but when I go to <code>findViewById()</code> for one of the <code>TextView</code>s in the first <code>Fragment</code> it throws a <code>NullPointerException</code>. I, for the life of me, can't figure out why.</p>
<p>Here's my code so far, let me know if more is needed please.</p>
<pre><code>public class SheetActivity extends FragmentActivity {
// /////////////////////////////////////////////////////////////////////////
// Variable Declaration
// /////////////////////////////////////////////////////////////////////////
private ViewPager viewPager;
private PagerTitleStrip titleStrip;
private String type;
private FragmentPagerAdapter fragmentPager; //UPDATE
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sheet);
viewPager = (ViewPager) findViewById(R.id.viewPager);
titleStrip = (PagerTitleStrip) findViewById(R.id.viewPagerTitleStrip);
// Determine which type of sheet to create
Intent intent = getIntent();
this.type = intent.getStringExtra("type");
FragmentManager manager = getSupportFragmentManager();
switch (type) {
case "1":
viewPager.setAdapter(new InstallAdapter(manager));
break;
case "2":
viewPager.setAdapter(new InstallAdapter(manager));
break;
}
fragmentPager = (FragmentPagerAdapter) viewPager.getAdapter(); //UPDATE
}
@Override
public void onResume() {
super.onResume();
fragmentPager.getItem(0).setText("something"); //UPDATE
}
class MyAdapter extends FragmentPagerAdapter {
private final String[] TITLES = { "Title1", "Title2" };
private final int PAGE_COUNT = TITLES.length;
private ArrayList<Fragment> FRAGMENTS = null;
public MyAdapter(FragmentManager fm) {
super(fm);
FRAGMENTS = new ArrayList<Fragment>();
FRAGMENTS.add(new FragmentA());
FRAGMENTS.add(new FragmentB());
}
@Override
public Fragment getItem(int pos) {
return FRAGMENTS.get(pos);
}
@Override
public int getCount() {
return PAGE_COUNT;
}
@Override
public CharSequence getPageTitle(int pos) {
return TITLES[pos];
}
}
}
</code></pre>
<p>All of <code>Fragment</code>s I created only have the <code>onCreateView()</code> method overridden so I can display the proper XML layout. Other than that they are 'stock'. Why can't I interact with elements in any of the <code>Fragment</code>s?</p>
<p><strong>UPDATE:</strong></p>
<p>So do something like this?</p>
<pre><code>public class FragmentA extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle inState) {
return inflater.inflate(R.layout.fragment_a, container, false);
}
public void setText(String text) {
TextView t = (TextView) getView().findViewById(R.id.someTextView); //UPDATE
t.setText(text);
}
}
</code></pre>
<p><strong>XML LAYOUT FOR FRAGMENT A</strong></p>
<pre><code><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="@+id/someTextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"

Ant JUnit ClassNotFoundException
|
<p>I realize there are a lot of similar questions as <a href="https://stackoverflow.com/questions/10658636/new-to-ant-classnotfoundexception-with-junit">this one</a>, however after reading over most of them I seem to be having the same problem, but for different reasons.</p>
<p>I'm running a <code><junit></code> task inside my Ant build and am getting a <code>ClassNotFoundException</code>. In most of the similarly-related questions (such as the one above), this turned out to be various degrees of the author simply not configuring the JUnit classpath correctly. Although it may very well be the same for me, none of the suggestions to any of these other questions have worked for me.</p>
<p>My project directory structure:</p>
<pre><code>MyProject/

<p>In <code>src/test/java/FakeObjectUnitTest.java</code>:</p>
<pre><code>// Package and imports omitted
public class FakeObjectUnitTest {
@Test
public void doSomething() {
int x = 5;
Assert.assertEquals(x, 5);
}
}
</code></pre>

<p>When I run this target from the command-line:</p>
<pre><code>run-junit:
[echo] Conducting unit tests with JUnit.
[echo] JUnit ClassPath is: /<path-to-my-project>/MyProject/lib/test/hamcrest-1.1.jar:/<path-to-my-project>/MyProject/lib/test/junit-4.10.jar:/<path-to-my-project>/MyProject/bin/main/com/myproject/client/FakeObject.class:/<path-to-my-project>/MyProject/bin/test/com/myproject/client/FakeObjectUnitTest.class
[junit] Running com.myproject.client.FakeObjectUnitTest

</code></pre>
<p>I do this to <em>prove</em> that it sees <code>FakeObjectUnitTest.class</code> on the JUnit classpath. However, it fails with an error. When I go into the XML TEST report for this test, I see the following:</p>
<pre><code><error message="com.myproject.client.FakeObjectUnitTest" type="java.lang.ClassNotFoundException">java.lang.ClassNotFoundException: com.myproject.client.FakeObjectUnitTest

</code></pre>
<p>When I run Ant in verbose mode (<code>-v</code>) the only <em>hint</em> I see are a bunch of warnings along the lines of:</p>
<blockquote>
<p>Ignoring Exception java.util.zip.ZipException: error in opening zip file reading resource x</p>
</blockquote>
<p>...where <code>x</code> is the name of a class file.</p>
<p>I found <a href="https://stackoverflow.com/questions/6015092/zipexception-when-running-junit-tests">this</a> question on SO, and the problem turned out to be that the author had added class files to the classpath, not JARs (which makes JUnit unhappy). So I tried removing <code>main.class.path</code> and <code>test.class.path</code> from <code>junit.class/path</code> and then I get an exception that none of the class files can be found.</p>
<p>Any ideas or thoughts as to what is going on? Thanks in advance, and sorry for the <code>-v</code> question here, but I figured the more details, the better.</p>

Filtering database rows with spring-data-jpa and spring-mvc
|
<p>I have a spring-mvc project that is using spring-data-jpa for data access. I have a domain object called <code>Travel</code> which I want to allow the end-user to apply a number of filters to it.</p>
<p>For that, I've implemented the following controller:</p>
<pre><code>@Autowired
private TravelRepository travelRep;
@RequestMapping("/search")
public ModelAndView search(
@RequestParam(required= false, defaultValue="") String lastName,
Pageable pageable) {
ModelAndView mav = new ModelAndView("travels/list");
Page<Travel> travels = travelRep.findByLastNameLike("%"+lastName+"%", pageable);
PageWrapper<Travel> page = new PageWrapper<Travel>(travels, "/search");
mav.addObject("page", page);
mav.addObject("lastName", lastName);
return mav;
}
</code></pre>
<p>This works fine: The user has a form with a <code>lastName</code> input box which can be used to filter the Travels. </p>
<p>Beyond lastName, my <code>Travel</code> domain object has a lot more attributes by which I'd like to filter. I think that if these attributes were all strings then I could add them as <code>@RequestParam</code>s and add a spring-data-jpa method to query by these. For instance I'd add a method <code>findByLastNameLikeAndFirstNameLikeAndShipNameLike</code>.</p>
<p>However, I don't know how should I do it when I need to filter for foreign keys. So my <code>Travel</code> has a <code>period</code> attribute that is a foreign key to the <code>Period</code> domain object, which I need to have it as a dropdown for the user to select the <code>Period</code>. </p>
<p>What I want to do is when the period is null I want to retrieve all travels filtered by the lastName and when the period is not null I want to retrieve all travels for this period filtered by the lastName. </p>
<p>I know that this can be done if I implement two methods in my repository and use an <code>if</code> to my controller:</p>
<pre><code>public ModelAndView search(
@RequestParam(required= false, defaultValue="") String lastName,
@RequestParam(required= false, defaultValue=null) Period period,
Pageable pageable) {
ModelAndView mav = new ModelAndView("travels/list");
Page travels = null;
if(period==null) {
travels = travelRep.findByLastNameLike("%"+lastName+"%", pageable);
} else {
travels = travelRep.findByPeriodAndLastNameLike(period,"%"+lastName+"%", pageable);
}
mav.addObject("page", page);
mav.addObject("period", period);
mav.addObject("lastName", lastName);
return mav;
}
</code></pre>
<p>Is there a way to do this <em>without</em> using the <code>if</code> ? My Travel has not only the period but also other attributes that need to be filtered using dropdowns !! As you can understand, the complexity would be exponentially increased when I need to use more dropdowns because all the combinations'd need to be considered :(</p>
<p><b>Update 03/12/13</b>: Continuing from M. Deinum's excelent answer, and after actually implementing it, I'd like to provide some comments for completeness of the question/asnwer:</p>
<ol>
<li><p>Instead of implementing <code>JpaSpecificationExecutor</code> you should implement <code>JpaSpecificationExecutor<Travel></code> to avoid type check warnings.</p></li>
<li><p>Please take a look at kostja's excellent answer to this question
<a href="https://stackoverflow.com/questions/11138118/really-dynamic-jpa-criteriabuilder">Really dynamic JPA CriteriaBuilder</a>
since you <em>will</em> need to implement this if you want to have correct filters.</p></li>
<li><p>The best documentation I was able to find for the Criteria API was <a href="http://www.ibm.com/developerworks/library/j-typesafejpa/" rel="noreferrer">http://www.ibm.com/developerworks/library/j-typesafejpa/</a>. This is a rather long read but I totally recommend it - after reading it most of my questions for Root and CriteriaBuilder were answered :)</p></li>
<li><p>Reusing the <code>Travel</code> object was not possible because it contained various other objects (who also contained other objects) which I needed to search for using <code>Like</code> - instead I used a <code>TravelSearch</code> object that contained the fields I needed to search for.</p></li>
</ol>
<p><b>Update 10/05/15</b>: As per @priyank's request, here's how I implemented the TravelSearch object:</p>
<pre><code>public class TravelSearch {
private String lastName;
private School school;
private Period period;
private String companyName;
private TravelTypeEnum travelType;
private TravelStatusEnum travelStatus;
// Setters + Getters
}
</code></pre>
<p>This object was used by TravelSpecification (most of the code is domain specific but I'm leaving it there as an example):</p>
<pre><code>public class TravelSpecification implements Specification<Travel> {
private TravelSearch criteria;
public TravelSpecification(TravelSearch ts) {
criteria= ts;
}
@Override
public Predicate toPredicate(Root<Travel> root, CriteriaQuery<?> query,
CriteriaBuilder cb) {
Join<Travel, Candidacy> o = root.join(Travel_.candidacy);
Path<Candidacy> candidacy = root.get(Travel_.candidacy);
Path<Student> student = candidacy.get(Candidacy_.student);
Path<String> lastName = student.get(Student_.lastName);
Path<School> school = student.get(Student_.school);
Path<Period> period = candidacy.get(Candidacy_.period);
Path<TravelStatusEnum> travelStatus = root.get(Travel_.travelStatus);
Path<TravelTypeEnum> travelType = root.get(Travel_.travelType);
Path<Company> company = root.get(Travel_.company);
Path<String> companyName = company.get(Company_.name);
final List<Predicate> predicates = new ArrayList<Predicate>();
if(criteria.getSchool()!=null) {
predicates.add(cb.equal(school, criteria.getSchool()));
}
if(criteria.getCompanyName()!=null) {
predicates.add(cb.like(companyName, "%"+criteria.getCompanyName()+"%"));
}
if(criteria.getPeriod()!=null) {
predicates.add(cb.equal(period, criteria.getPeriod()));
}
if(criteria.getTravelStatus()!=null) {
predicates.add(cb.equal(travelStatus, criteria.getTravelStatus()));
}
if(criteria.getTravelType()!=null) {
predicates.add(cb.equal(travelType, criteria.getTravelType()));
}
if(criteria.getLastName()!=null ) {
predicates.add(cb.like(lastName, "%"+criteria.getLastName()+"%"));
}
return cb.and(predicates.toArray(new Predicate[predicates.size()]));
}
}
</code></pre>
<p>Finally, here's my search method:</p>
<pre><code>@RequestMapping("/search")
public ModelAndView search(
@ModelAttribute TravelSearch travelSearch,
Pageable pageable) {
ModelAndView mav = new ModelAndView("travels/list");
TravelSpecification tspec = new TravelSpecification(travelSearch);
Page<Travel> travels = travelRep.findAll(tspec, pageable);
PageWrapper<Travel> page = new PageWrapper<Travel>(travels, "/search");
mav.addObject(travelSearch);
mav.addObject("page", page);
mav.addObject("schools", schoolRep.findAll() );
mav.addObject("periods", periodRep.findAll() );
mav.addObject("travelTypes", TravelTypeEnum.values());
mav.addObject("travelStatuses", TravelStatusEnum.values());
return mav;
}
</code></pre>
<p>Hope I helped!</p>

Errors installing PyAudio "Failed Building Wheel for PyAudio"
|
<p>I have been having trouble finding a fix for getting PyAudio installed on my machine. I have tried a few different solutions and i do have the prerequisite library "portaudio" installed using homebrew. I have also looked for solutions to the gcc error that appears at the bottom of the output and to which solutions only generated a different error that read "Error: command ‘clang’ failed with exit status 1". I feel at this point it is some lack of understanding of the implications of these error messages due to a lack of experience in python that keeps me from understanding a resolution. Any help is greatly appreciated. Thank you.</p>

How do I use Java to read a .csv file and insert its data into SQL Server?
|
<p>I am very new to Java. I have a task with two steps.</p>
<ol>
<li>I want to read all data from a <code>.csv</code> file.</li>
<li>After reading that data I have to put it into a SQL Server database.</li>
</ol>
<p>I have done step one. I'm able to read the <code>.csv</code> file data, but I don't know that how to insert it into a database.</p>
<p>Here's my code for fetching the <code>.csv</code> file data:</p>
<pre><code>import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.StringTokenizer;
public class DBcvsdataextractor {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
String fileName="D:/USPresident Wikipedia URLs Thumbs HS.csv";
try {
BufferedReader br = new BufferedReader( new FileReader(fileName));
StringTokenizer st = null;
int lineNumber = 0, tokenNumber = 0;
while( (fileName = br.readLine()) != null)
{
if(lineNumber++ == 0)
continue;
//break comma separated line using ","
st = new StringTokenizer(fileName, ",");
while(st.hasMoreTokens())
{
//display csv values
tokenNumber++;
System.out.print(st.nextToken() + '\t');
}
//new line
System.out.println(" ");
//reset token number
tokenNumber = 0;
}
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
</code></pre>
<p>Now, how do I insert that data into SQL Server?</p>

Difference between an empty ArrayList and an ArrayList with null elements?
|
<p>I am coding some validators for a REST service which parse a JSON and I found out something that sounds wierd for me (I am not a <strong><em>JAVA expert</em></strong> at all).</p>
<p>Consider having two <strong><em>ArrayLists</em></strong>: </p>
<pre><code>ArrayList<Object> list1 = new ArrayList<Object>();
ArrayList<Object> list2 = new ArrayList<Object>();
</code></pre>
<p>Both lists have something in <strong><em>common</em></strong>: they are <em>completely empty</em> (or full of null elements). But if I do:</p>
<pre><code>list1.add(null);
</code></pre>
<p>Although both remain completely <strong><em>empty</em></strong>, <em>they have completely different behaviors</em>. And to make some methods the results are <strong><em>very different</em></strong>:</p>
<pre><code>System.out.println(list1.contains(null)); //prints true!
System.out.println(list2.contains(null)); //prints false
System.out.println(CollectionUtils.isNotEmpty(list1)); //prints true
System.out.println(CollectionUtils.isNotEmpty(list2)); //prints false
System.out.println(list1.size()); //prints 1
System.out.println(list2.size()); //prints 0
</code></pre>
<p>Doing some research, and looking at the implementation of each of these methods, you can determine the reason for these differences, but still do not understand why it would be valid or useful to differentiate between these lists.</p>
<ul>
<li>Why <strong><em>add(item)</em></strong> doesnt validate if <strong>item!=null</strong> ? </li>
<li>Why <strong><em>contains(null)</em></strong> says <strong>false</strong> if the list is full of <strong>nulls</strong>?</li>
</ul>
<p>Thanks in advance!!!</p>
<p><strong><em>EDIT:</em></strong></p>
<p>I am mostly agree whit the answers, but I'm not yet convinced all. This is the implementation of the method remove:</p>
<pre><code>/**
* Removes the first occurrence of the specified element from this list,
* if it is present. If the list does not contain the element, it is
* unchanged. More formally, removes the element with the lowest index
* <tt>i</tt> such that
* <tt>(o==null&nbsp;?&nbsp;get(i)==null&nbsp;:&nbsp;o.equals(get(i)))</tt>
* (if such an element exists). Returns <tt>true</tt> if this list
* contained the specified element (or equivalently, if this list
* changed as a result of the call).
*
* @param o element to be removed from this list, if present
* @return <tt>true</tt> if this list contained the specified element
*/
public boolean remove(Object o) {
if (o == null) {
for (int index = 0; index < size; index++)
if (elementData[index] == null) {
fastRemove(index);
return true;
}
} else {
for (int index = 0; index < size; index++)
if (o.equals(elementData[index])) {
fastRemove(index);
return true;
}
}
return false;
}
/*
* Private remove method that skips bounds checking and does not
* return the value removed.
*/
private void fastRemove(int index) {
modCount++;
int numMoved = size - index - 1;
if (numMoved > 0)
System.arraycopy(elementData, index+1, elementData, index,
numMoved);
elementData[--size] = null; // clear to let GC do its work
}
</code></pre>
<p>So, now if i do:</p>
<pre><code>ArrayList<Object> list = new ArrayList<Object>();
list.add(null);
System.out.println(list.contains(null)); //prints true!
list.remove(null);
System.out.println(list.contains(null)); //prints false!
</code></pre>
<p><strong><em>what I'm missing?</em></strong></p>

<p>And after i expect to get my LiveData in ViewModel:</p>
<pre><code>open class EventSingleViewModel: ViewModel(), RepositoryComponent.Injectable {

@Inject lateinit var eventRepository: EventRepository
var eventSingle: LiveData<RequestReader<Event>>? = null

eventSingle = eventRepository.loadSingle(eventId)

</code></pre>
<p><strong>The problem.</strong>
I'm getting a list of events the same way (it works!) I've described above, but with a single event (this event is already in database) it doesn't work. I've found out that localSource.value is null (in <strong>NetworkManager</strong>). Maybe my query is bad or.. something else.</p>

Filling empty cells in CSS Grid Layout
|
<p>I have a set of div tiles that I've arranged through the CSS Grid Layout as "automatically" as possible; my final idea is that even if I don't know how many tiles there are, they all get sized and placed correctly. This is working fine.</p>
<p>Now, I'm looking to double the area of any tile that is clicked on. As far as I know, that means increasing the span of this tile:</p>
<pre><code>grid-row: span 2;
grid-column: span 2;
</code></pre>
<p>I'm happy with the results if I click on any tile that is not in the right-most column. When the rightmost tiles get expanded, they are wrapped down onto the next line.</p>
<p>Is there any way to force these tiles to expand to the left, so that other non-active tiles are wrapped instead?</p>

EntityDataSource and Entity Framework 6
|
<p>I am learning ASP.NET. I came to EntityDataSorce control. I am using EF6. I have read that this control and EF6 have some issues, conflicts, but with the last update to EntityDataSource this issue has solved. <a href="http://blogs.msdn.com/b/webdev/archive/2014/02/28/announcing-the-release-of-dynamic-data-provider-and-entitydatasource-control-for-entity-framework-6.aspx" rel="noreferrer">http://blogs.msdn.com/b/webdev/archive/2014/02/28/announcing-the-release-of-dynamic-data-provider-and-entitydatasource-control-for-entity-framework-6.aspx</a></p>
<p>I am trying to follow above link. First I create an .edmx model</p>
<p><img src="https://i.stack.imgur.com/xgY4N.png" alt="enter image description here"></p>
<p>Install new EntityDataSource Contro with NuGet</p>
<p><img src="https://i.stack.imgur.com/8URUS.png" alt="enter image description here"></p>
<p>I added two EntityDataSource controls and changed prefix of one of them to ef. So I have two control one of them is old and other one is new updated</p>
<p><img src="https://i.stack.imgur.com/6ggxs.png" alt="enter image description here"></p>
<p>When I click the old one I can see the configuration popup and reach the Configure Data Source screen. But when click on the new one there is no popup. So, how can I configure data source?
What is wrong with this?</p>

"GPU process isn't usable. Goodbye."
|
<p>I'm experimenting with building a Windows and Mac OS app using Electron and have hit a snag.</p>
<p>In short, if I try to run the application directly with Electron on Mac OS Big Sur (as opposed to building a Mac app and then running that) I get the following error returned:</p>
<pre><code>[35941:0821/171720.038162:FATAL:gpu_data_manager_impl_private.cc(415)] GPU process isn't usable. Goodbye.
</code></pre>
<p>I am running directly with Electron using the following in my <code>package.json</code>:</p>
<pre><code>"scripts": {
...
"test": "electron main.js",
...
}
</code></pre>
<p>So far the only Mac OS environment I have access to is Big Sur so haven't tried this on earlier versions of Mac OS but from Googling it seems this error may be related to Big Sur's tightened security/sandbox constraints -- but I am guessing about that.</p>
<p>In any case, after some Googling several suggestions indicated trying to run without the app sandbox, i.e. adding this to <code>main.js</code>:</p>
<pre><code>app.commandLine.appendSwitch('no-sandbox');
</code></pre>
<p>That's all well and good and works.</p>
<p>However, if I ever want to build and distribute a signed Mac app targeting the Mac App store or a just a signed, sandboxed DMG or PKG installer, then this won't be suitable.</p>
<p>If I remove the above <code>no-sandbox</code> command from <code>main.js</code> and specify the app sandbox in my entitlements <code>plist</code> as shown below the resulting signed app will not run:</p>
<pre><code><key>com.apple.security.app-sandbox</key>
<true/>
</code></pre>
<p>The app tries to open and just closes. I can try running at the command line with <code>open <appname>.app</code> but this throws the following error in the console:</p>
<pre><code>The application cannot be opened for an unexpected reason, error=Error Domain=NSOSStatusErrorDomain Code=-10826 "kLSNoLaunchPermissionErr: User doesn't have permission to launch the app (managed networks)" UserInfo={_LSFunction=_LSLaunchWithRunningboard, _LSLine=2561, NSUnderlyingError=0x7fd3c9c13db0 {Error Domain=RBSRequestErrorDomain Code=5 "Launch failed." UserInfo={NSLocalizedFailureReason=Launch failed., NSUnderlyingError=0x7fd3c9c158e0 {Error Domain=NSPOSIXErrorDomain Code=153 "Unknown error: 153" UserInfo={NSLocalizedDescription=Launchd job spawn failed with error: 153}}}}}
</code></pre>
<p>If I build a signed app with <code>no-sandbox</code> enabled, the app will run just fine on Big Sur using <code>open <appname>.app</code>.</p>
<p>I have tried my best through Google, Stack Overflow, etc to diagnose this but am not getting anywhere. Here's to hoping the Stack Overflow community can provide me the critical clue to solving this.</p>
<p>For further context, I created a new, empty Electron application and followed the <a href="https://www.electronjs.org/docs/latest/tutorial/quick-start" rel="noreferrer">Electron Quick Start Guide</a> to the section where it describes creating an empty <code>main.js</code> which technically should allow the Electron app to start -- but it won't. The same error describe above re the GPU gets thrown even without instantiating a <code>BrowserWindow</code> or writing any custom code of my own.</p>
<p>NEW UPDATE: I set these environment variables to true and then tried running the app with <code>npm start</code>:</p>
<ul>
<li><code>ELECTRON_ENABLE_LOGGING</code></li>
<li><code>ELECTRON_DEBUG_NOTIFICATIONS</code></li>
<li><code>ELECTRON_ENABLE_STACK_DUMPING</code></li>
</ul>
<p>The result is more detailed error output:</p>
<pre><code>[48836:0823/165857.676747:ERROR:icu_util.cc(179)] icudtl.dat not found in bundle

</code></pre>
<p>Haven't had time to do the research as to what ICU refers to but thought I would update with this info.</p>
<p>ANOTHER UPDATE: all this has been done on Mac OS Big Sur which is my main development machine. Trying this on a Windows 10 machine, using the same Electron code, dependencies, etc and things work fine. So the problem is either related to Mac OS Big Sur or a specific local issue on my development machine which I cannot identify. Any suggestions on how to diagnose this will be much appreciated.</p>
<p>ONE MORE UPDATE: Based on a guess, I created a new user on my mac, took the code in there and it ran perfectly. So -- this probably means that I need to find something installed in my profile or some corruption in my own profile/settings that is breaking things. As always, any suggestions appreciated it.</p>

#include "llvm/LLVMContext.h"
int main(int argc, char **argv) {
llvm::Module *module = new llvm::Module("test", llvm::getGlobalContext());

/index.php //iioengine.com (homepage)
/.htaccess //file doesn't work

</code></pre>
<p>Is the issue that I'm using two different htaccess files?</p>
<p>Here is a link that needs to work: <a href="http://iioengine.com/demos" rel="nofollow noreferrer">http://iioengine.com/demos</a></p>
<p>I noticed that this current htaccess file disrupts all of the forums URL's as well</p>
<p>This no longer works: <a href="http://iioengine.com/forums/Forum-Box2D" rel="nofollow noreferrer">http://iioengine.com/forums/Forum-Box2D</a></p>
<p>EDIT: Thanks for reopening, I have made some progress. Here is my current htaccess file:</p>
<pre><code><IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

</code></pre>
<p>I still get 404 pages, but if I put this line in:</p>
<p><code>RewriteRule . /index.php [L]</code></p>
<p>all non-'.php' requests get forwarded to the homepage... So mod_rewrite is definitely enabled, it's just not working right. Anyone know what the issue could be? </p>
<p><strong>EDIT</strong>: This is <strong>not a duplicate</strong> - none of the other solutions work for me. My question is not <em>do solutions exist</em>, its <em>why aren't they working for me</em>. No one has been able to resolve this, I have been trying many solutions myself. Isn't the point of this forum to get solutions to specific issues?</p>
<p>Allow me to clarify...</p>
<p>I have MyBB running in a subfolder and its rewrites work fine. This link, for instance, works: <a href="http://iioengine.com/forums/Forum-Box2D" rel="nofollow noreferrer">http://iioengine.com/forums/Forum-Box2D</a></p>
<p>All the php pages that are not part of MyBB still have the .php extension in their URLs - I am trying to remove these but nothing is working. Example: <a href="http://iioengine.com/demos" rel="nofollow noreferrer">http://iioengine.com/demos</a></p>
<p>... [original post]</p>
<p>There is obviously a lot of information out there about this, but I have tried almost a dozen different solutions and have not gotten past a 404 page.</p>
<p>Here is my site: <a href="http://iioengine.com/" rel="nofollow noreferrer">http://iioengine.com/</a>, all pages are php, and everything other than the homepage and all of the forums pages have a '.php' at the end of their URL that I would like to remove.</p>
<p>In addition to redirecting non-'.php' requests to the correct pages, I would also like to remove the '.php' part even when it is part of the request (because all of my content already specifies '.php' in its hyperlinks).</p>
<p>This is what I have so far, mostly taken from <a href="https://stackoverflow.com/questions/9821222/remove-php-extension-explicitly-written-for-friendly-url">this post</a>, but it doesn't work, I get a 404 page.</p>

How to Quickly Remove Items From a List
|
<p>I am looking for a way to quickly remove items from a C# <code>List<T></code>. The documentation states that the <code>List.Remove()</code> and <code>List.RemoveAt()</code> operations are both <code>O(n)</code></p>
<ul>
<li><a href="http://msdn.microsoft.com/en-us/library/cd666k3e.aspx" rel="noreferrer">List.Remove</a></li>
<li><a href="http://msdn.microsoft.com/en-us/library/5cw9x18z%28v=vs.80%29.aspx" rel="noreferrer">List.RemoveAt</a></li>
</ul>
<p>This is severely affecting my application.</p>
<p>I wrote a few different remove methods and tested them all on a <code>List<String></code> with 500,000 items. The test cases are shown below...</p>
<hr>
<p><strong>Overview</strong></p>
<p>I wrote a method that would generate a list of strings that simply contains string representations of each number ("1", "2", "3", ...). I then attempted to <code>remove</code> every 5th item in the list. Here is the method used to generate the list:</p>
<pre><code>private List<String> GetList(int size)
{
List<String> myList = new List<String>();
for (int i = 0; i < size; i++)
myList.Add(i.ToString());
return myList;
}
</code></pre>
<p><strong>Test 1: RemoveAt()</strong></p>
<p>Here is the test I used to test the <code>RemoveAt()</code> method.</p>
<pre><code>private void RemoveTest1(ref List<String> list)
{
for (int i = 0; i < list.Count; i++)
if (i % 5 == 0)
list.RemoveAt(i);
}
</code></pre>
<p><strong>Test 2: Remove()</strong></p>
<p>Here is the test I used to test the <code>Remove()</code> method.</p>
<pre><code>private void RemoveTest2(ref List<String> list)
{
List<int> itemsToRemove = new List<int>();
for (int i = 0; i < list.Count; i++)
if (i % 5 == 0)
list.Remove(list[i]);
}
</code></pre>
<p><strong>Test 3: Set to null, sort, then RemoveRange</strong></p>
<p>In this test, I looped through the list one time and set the to-be-removed items to <code>null</code>. Then, I sorted the list (so null would be at the top), and removed all the items at the top that were set to null.
NOTE: This reordered my list, so I may have to go put it back in the correct order.</p>
<pre><code>private void RemoveTest3(ref List<String> list)
{
int numToRemove = 0;
for (int i = 0; i < list.Count; i++)
{
if (i % 5 == 0)
{
list[i] = null;
numToRemove++;
}
}
list.Sort();
list.RemoveRange(0, numToRemove);
// Now they're out of order...
}
</code></pre>
<p><strong>Test 4: Create a new list, and add all of the "good" values to the new list</strong></p>
<p>In this test, I created a new list, and added all of my keep-items to the new list. Then, I put all of these items into the original list.</p>
<pre><code>private void RemoveTest4(ref List<String> list)
{
List<String> newList = new List<String>();
for (int i = 0; i < list.Count; i++)
{
if (i % 5 == 0)
continue;
else
newList.Add(list[i]);
}
list.RemoveRange(0, list.Count);
list.AddRange(newList);
}
</code></pre>
<p><strong>Test 5: Set to null and then FindAll()</strong></p>
<p>In this test, I set all the to-be-deleted items to <code>null</code>, then used the <code>FindAll()</code> feature to find all the items that are not <code>null</code></p>
<pre><code>private void RemoveTest5(ref List<String> list)
{
for (int i = 0; i < list.Count; i++)
if (i % 5 == 0)
list[i] = null;
list = list.FindAll(x => x != null);
}
</code></pre>
<p><strong>Test 6: Set to null and then RemoveAll()</strong></p>
<p>In this test, I set all the to-be-deleted items to <code>null</code>, then used the <code>RemoveAll()</code> feature to remove all the items that are not <code>null</code></p>
<pre><code>private void RemoveTest6(ref List<String> list)
{
for (int i = 0; i < list.Count; i++)
if (i % 5 == 0)
list[i] = null;
list.RemoveAll(x => x == null);
}
</code></pre>
<hr>
<p><strong>Client Application and Outputs</strong></p>
<pre><code>int numItems = 500000;

<p><strong>Notes And Comments</strong></p>
<ul>
<li><p>The first two tests do not actually remove every 5th item from the list, because the list is being reordered after each remove. In fact, out of 500,000 items, only 83,334 were removed (should have been 100,000). I am okay with this - clearly the Remove()/RemoveAt() methods are not a good idea anyway.</p></li>
<li><p>Although I tried to remove the 5th item from the list, in <em>reality</em> there will not be such a pattern. Entries to be removed will be random.</p></li>
<li><p>Although I used a <code>List<String></code> in this example, that will not always be the case. It could be a <code>List<Anything></code></p></li>
<li><p>Not putting the items in the list to begin with is <strong>not</strong> an option.</p></li>
<li><p>The other methods (3 - 6) all performed much better, <em>comparatively</em>, however I am a little concerned -- In 3, 5, and 6 I was forced to set a value to <code>null</code>, and then remove all the items according to this sentinel. I don't like that approach because I can envision a scenario where one of the items in the list might be <code>null</code> and it would get removed unintentionally.</p></li>
</ul>
<p>My question is: What is the best way to quickly remove many items from a <code>List<T></code>? Most of the approaches I've tried look really ugly, and potentially dangerous, to me. Is a <code>List</code> the wrong data structure?</p>
<p>Right now, I am leaning towards creating a new list and adding the good items to the new list, but it seems like there should be a better way.</p>

CoreData and SwiftUI: Context in environment is not connected to a persistent store coordinator
|
<p>I am trying to teach myself Core Data by building a homework managing app. My code builds fine and the app runs okay until I try to add a new assignment to the list. I get this error <code>Thread 1: EXC_BREAKPOINT (code=1, subcode=0x1c25719e8)</code> on the following line: <code>ForEach(courses, id: \.self) { course in</code>. The console also has this error: <code>Context in environment is not connected to a persistent store coordinator: <NSManagedObjectContext: 0x2823cb3a0></code>.</p>
<p>I know very little about Core Data and am at a loss as to what the issue might be. I have set up "Assignment" and "Course" entities in the data model, where Course has a one-to-many relationship to Assignment. Each assignment will be categorized under a particular course.</p>
<p>This is the code for the view that adds a new assignment to the list:</p>
<pre><code> struct NewAssignmentView: View {
@Environment(\.presentationMode) var presentationMode
@Environment(\.managedObjectContext) var moc
@FetchRequest(entity: Course.entity(), sortDescriptors: []) var courses: FetchedResults<Course>
@State var name = ""
@State var hasDueDate = false
@State var dueDate = Date()
@State var course = Course()
var body: some View {
NavigationView {
Form {
TextField("Assignment Name", text: $name)
Section {
Picker("Course", selection: $course) {
ForEach(courses, id: \.self) { course in
Text("\(course.name ?? "")").foregroundColor(course.color)
}
}
}
Section {
Toggle(isOn: $hasDueDate.animation()) {
Text("Due Date")
}
if hasDueDate {
DatePicker(selection: $dueDate, displayedComponents: .date, label: { Text("Set Date:") })
}
}
}
.navigationBarTitle("New Assignment", displayMode: .inline)
.navigationBarItems(leading: Button(action: {
self.presentationMode.wrappedValue.dismiss()
}, label: { Text("Cancel") }),
trailing: Button(action: {
let newAssignment = Assignment(context: self.moc)
newAssignment.name = self.name
newAssignment.hasDueDate = self.hasDueDate
newAssignment.dueDate = self.dueDate
newAssignment.statusString = Status.incomplete.rawValue
newAssignment.course = self.course
self.presentationMode.wrappedValue.dismiss()
}, label: { Text("Add").bold() }))
}
}
}
</code></pre>
<p>EDIT: Here is the code in AppDelegate that sets up the persistent container:</p>
<pre><code>lazy var persistentContainer: NSPersistentCloudKitContainer = {
let container = NSPersistentCloudKitContainer(name: "test")
container.loadPersistentStores(completionHandler: { (storeDescription, error) in
if let error = error as NSError? {
fatalError("Unresolved error \(error), \(error.userInfo)")
}
})
return container
}()
</code></pre>
<p>And the code in SceneDelegate that sets up the environment:</p>
<pre><code> func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
// Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
// If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
// This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
// Get the managed object context from the shared persistent container.
let context = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext
// Create the SwiftUI view and set the context as the value for the managedObjectContext environment keyPath.
// Add `@Environment(\.managedObjectContext)` in the views that will need the context.
let contentView = ContentView().environment(\.managedObjectContext, context)
// Use a UIHostingController as window root view controller.
if let windowScene = scene as? UIWindowScene {
let window = UIWindow(windowScene: windowScene)
window.rootViewController = UIHostingController(rootView: contentView)
self.window = window
window.makeKeyAndVisible()
}
}

Delphi Queue and Synchronize

<p>I always use <code>Synchronize</code> but this time I have tried with <code>Queue</code> because according to Nick it is better in case of multiple requests since they won't be "serialized" and executed one by one. The code above works fine. Why this is not working instead?</p>
<pre><code> TThread.CreateAnonymousThread(
procedure
begin
TThread.Queue(TThread.Current, procedure
begin
Memo1.Lines.Clear;
Memo1.Lines.Add('start');
end);
Sleep(2000);
TThread.Queue(TThread.Current, procedure
begin
Memo1.Lines.Add('end');
end);
end
).Start;
</code></pre>
<p>In this case the Memo outputs the <code>start</code> but not the end. When I call:</p>
<ul>
<li>Synchronize on the first and Synchronize on the second it works</li>
<li>Queue on the first and Synchronize on the second it works</li>
<li>Queue both times it's not working because I see only the <code>start</code> in the memo</li>
</ul>

WPF Template Binding in ToggleButton UserControl
|
<p>I'm developing a basic dip-switch user control as a personal learning exercise. Originally I had it set up where you could declare some custom color properties on the user control, and they would be used on elements inside the control.</p>
<p>However, I recenly discovered ToggleButtons, and rebuilt my control to take advantage of them. Since then, my custom color properties (SwitchColor and SwitchBkgndColor) no longer work properly. They are always rendered with the default colors, not the colors I specified when I place them in my Window. Here's some code:</p>
<pre><code> <UserControl x:Class="DipSwitchToggleBtn"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:app="clr-namespace:SwitchesApp"
Width="20" Height="40">
<ToggleButton Name="ToggleBtn" IsThreeState="False">
<ToggleButton.Template>
<ControlTemplate>
<Canvas Name="SwitchBkgnd"
Background="{TemplateBinding app:DipSwitchToggleBtn.SwitchBkgndColor}"
>
<Rectangle Name="SwitchBlock"
Fill="{TemplateBinding app:DipSwitchToggleBtn.SwitchColor}"
Width="16" Height="16"
Canvas.Top="22"
Canvas.Left="2"
/>
</Canvas>
<ControlTemplate.Triggers>
<Trigger Property="ToggleButton.IsChecked" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetName="SwitchBlock"
Duration="00:00:00.05"
Storyboard.TargetProperty="(Canvas.Top)" To="2" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetName="SwitchBlock"
Duration="00:00:00.05"
Storyboard.TargetProperty="(Canvas.Top)" To="22" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</ToggleButton.Template>
</ToggleButton>
</UserControl>
</code></pre>
<p>...and the code behind:</p>
<pre><code>Partial Public Class DipSwitchToggleBtn
Public Property State() As Boolean
Get
Return Me.ToggleBtn.IsChecked
End Get
Set(ByVal value As Boolean)
Me.ToggleBtn.IsChecked = value
End Set
End Property
Public Sub Toggle()
Me.State = Not Me.State
End Sub
#Region " Visual Properties "
Public Shared ReadOnly SwitchColorProperty As DependencyProperty = _
DependencyProperty.Register("SwitchColor", _
GetType(Brush), GetType(DipSwitchToggleBtn), _
New FrameworkPropertyMetadata(Brushes.LightGray))
Public Property SwitchColor() As Brush
Get
Return GetValue(SwitchColorProperty)
End Get
Set(ByVal value As Brush)
SetValue(SwitchColorProperty, value)
End Set
End Property
Public Shared ReadOnly SwitchBkgndColorProperty As DependencyProperty = _
DependencyProperty.Register("SwitchBkgndColor", _
GetType(Brush), GetType(DipSwitchToggleBtn), _
New FrameworkPropertyMetadata(Brushes.Gray))
Public Property SwitchBkgndColor() As Brush
Get
Return GetValue(SwitchBkgndColorProperty)
End Get
Set(ByVal value As Brush)
SetValue(SwitchBkgndColorProperty, value)
End Set
End Property
#End Region
End Class
</code></pre>
<p>The default Gray and LightGray show up in the VS2008 designer and the compiled app, but when I do something like this in my window:</p>
<pre><code><app:DipSwitchToggleBtn x:Name="DipSwitchTest" SwitchColor="#0000FF" SwitchBkgndColor="#000000" />
</code></pre>
<p>The colors I specified for this instance do not get used. Everything compiles without error, but my control is still displayed with the default colors.</p>
<p>I believe there is some new hierarchy at play since I nested my items in the ToggleButton.</p>
<p>Any help would be appreciated. Thank you.</p>

php mysql compare long and lat, return ones under 10 miles
|
<p>Hay i want to find the distance (in miles) between 2 locations using lat and long values, and check if they are within a 10 mile radius of each other.</p>
<p>When a user logs in, their lat/long values are saved in a session</p>
<pre><code>$_SESSION['lat']
$_SESSION['long']
</code></pre>
<p>I have 2 functions</p>
<p>This one works out the distance in miles and returns a rounded value</p>
<pre><code>function distance($lat1, $lng1, $lat2, $lng2){
$pi80 = M_PI / 180;
$lat1 *= $pi80;
$lng1 *= $pi80;
$lat2 *= $pi80;
$lng2 *= $pi80;
$r = 6372.797; // mean radius of Earth in km
$dlat = $lat2 - $lat1;
$dlng = $lng2 - $lng1;
$a = sin($dlat / 2) * sin($dlat / 2) + cos($lat1) * cos($lat2) * sin($dlng / 2) * sin($dlng / 2);
$c = 2 * atan2(sqrt($a), sqrt(1 - $a));
$km = $r * $c;
return floor($km * 0.621371192);
}
</code></pre>
<p>This one returns a bool if the distance between the 2 sets of lat and long's is under 10.</p>
<pre><code>function is_within_10_miles($lat1, $lng1, $lat2, $lng2){
$d = distance($lat1, $lng1, $lat2, $lng2);
if( $d <= 10 ){
return True;
}else{
return False;
}
}
</code></pre>
<p>Both functions work as expected, if i give 2 sets of lat/longs and the distance between them is say 20 miles, my is_within_10_miles() function returns false.</p>
<p>Now, I have a database of 'locations' (4 fields - ID, name, lat, long).</p>
<p>I want to find all locations that are within a 10 mile radius.</p>
<p>Any ideas?</p>
<p><strong>EDIT: I can loop through ALL the and perform the is_within_10_miles() on them like this</strong></p>
<pre><code>$query = "SELECT * FROM `locations`";
$result = mysql_query($query);
while($location = mysql_fetch_assoc($result)){
echo $location['name']." is ";
echo distance($lat2, $lon2, $location['lat'], $location['lon']);
echo " miles form your house, is it with a 10 mile radius? ";
if( is_within_10_miles($lat2, $lon2, $location['lat'], $location['lon']) ){
echo "yeah";
}else{
echo "no";
}
echo "<br>";
</code></pre>
<p>}</p>
<p>A sample result would be</p>
<pre><code>goodison park is 7 miles form your house, is it with a 10 mile radius? yeah
</code></pre>
<p>I need to somehow perform the is_within_10_miles function within my query.</p>
<p>EDIT EDIT</p>
<p>This legend from <a href="http://www.zcentric.com/blog/2007/03/calculate_distance_in_mysql_wi.html" rel="noreferrer">http://www.zcentric.com/blog/2007/03/calculate_distance_in_mysql_wi.html</a> came up with this...</p>
<pre><code>SELECT ((ACOS(SIN($lat * PI() / 180) * SIN(lat * PI() / 180) + COS($lat * PI() / 180) * COS(lat * PI() / 180) * COS(($lon - lon) * PI() / 180)) * 180 / PI()) * 60 * 1.1515) AS distance FROM members HAVING distance<='10' ORDER BY distance ASC
</code></pre>
<p>It actually works. Problem is that i want to select * rows, rather than selecting them one by one. How do i do that?</p>

JQGrid - SetRowData - Returns success but no data updated
|
<p>I am trying to add/edit data into my JQGrid. Currently the first column is populated and then the other six are blank and are dependent upon the first column. So I need to <strong>add or "edit the blank" the data in the other six columns while the first remains the same.</strong> </p>
<p>Right now I am just trying to get access into the JQGrid to edit my current data. The function below is what I have setup so far. It gets passed the time (the first columns data), the number of ohms (data to enter the grid), and the column name. It builds my data set and then tries to add it to rowid 0. This is hardcoded just because I'm trying to get it to work right now. Then I access the JQGrid, add the rowdata and it actually returns a success, but nothing has been added to the JQGrid.</p>
<p>*note - this is all done within my javascript file</p>
<pre><code>function AddRow(elapsedTime, numMOhms, mColumn)
{
switch(mColumn)
{
case 'a':
case 'A':
dataToAdd = [{TestTime:elapsedTime,RdgA:numMOhms,CorrA:"",RdgB:"",CorrB:"",RdgC:"",CorrC:""}];
break;
case 'b':
case 'B':
dataToAdd = [{TestTime:elapsedTime,RdgA:"",CorrA:"",RdgB:numMOhms,CorrB:"",RdgC:"",CorrC:""}];
break;
case 'c':
case 'C':
dataToAdd = [{TestTime:elapsedTime,RdgA:"",CorrA:"",RdgB:"",CorrB:"",RdgC:numMOhms,CorrC:""}];
break;
}
alert(JSON.stringify(dataToAdd));
var success = jQuery("#polarizationTable").jqGrid('setRowData',0,dataToAdd[0]);
if(success)
{
alert("y");
}
DrawGraph(true);
}
</code></pre>
<p>if you replace the last bit with this:</p>
<pre><code>for(var i=0;i<=dataToAdd.length;i++)
jQuery("#polarizationTable").jqGrid('addRowData',i+1,dataToAdd[i]);
</code></pre>
<p>I can get it to add, but it is a dumb add and just appends that data to the end instead of updating data in that row. I tried modifying it with hardcode and removing the for loop, and no luck.</p>
<p>Here is what my colModel/colNames looks like.</p>
<pre><code>colNames:['Minutes','Reading A', 'Corr A', 'Reading B','Corr B','Reading C','Corr C'],
colModel:[
{name:'TestTime',index:'TestTime', align:"center", sortable:false},
{name:'RdgA',index:'RdgA', align:"center", sortable:false},
{name:'CorrA',index:'CorrA', align:"center", sortable:false},
{name:'RdgB',index:'RdgB', align:"center", sortable:false},
{name:'CorrB',index:'CorrB', align:"center", sortable:false},
{name:'RdgC',index:'RdgC', align:"center", sortable:false},
{name:'CorrC',index:'CorrC', align:"center", sortable:false}
],

possible ways to store JSON in dynamodb
|
<p>I am working on an implementation where my system will be integrated with an external application. This external application generates long and different json for every request.</p>
<p>I want to store this json in dynamodb, what would be the best approach to do that? Currently, I have created a POJO class with below property. In this definition property, I set the API response json as string.</p>
<pre><code>@DynamoDBAttribute(attributeName = "definition")
private String definition;
</code></pre>
<p>Then create object of POJO, and save it to dynamodb using <code>this.dynamoDBMapper.save(obj);</code> </p>
<p>Questions:</p>
<p>1 - Is this a good approach to store JSON in dynamodb as string?</p>
<p>2 - What if I want to search by any property of this json in dynamodb?</p>
<p>3 - Is there a better way to store this json so it can be searchable also?</p>
<p>Also, this json is always different so I can't map it to POJO class, that's why I am trying to store it as a string.</p>
<p>Below is my sample POJO object that I am storing in dynamo db.</p>
<pre><code>@DynamoDBTable(tableName = "job")
public class Job {
@DynamoDBHashKey(attributeName = "inbound_job")
private Long inboundId;
@DynamoDBAttribute(attributeName = "outbound_job")
private Long outboundId;
@DynamoDBAttribute(attributeName = "definition")
private String definition;
}
</code></pre>
<p>Below is respective json stored in dynamodb.</p>
<pre><code>{
"inbound_job": {
"N": "3138788"
},
"outbound_id": {
"N": "909092"

}
}

<p>I also want to search by any json property of "definition" attribute.</p>
<p>Let me know your thoughts.</p>

Elasticsearch Parse Exception error when attempting to index PDF
|
<p>I'm just getting started with elasticsearch. Our requirement has us needing to index thousands of PDF files and I'm having a hard time getting just ONE of them to index successfully.</p>
<p>Installed the Attachment Type plugin and got response: <code>Installed mapper-attachments</code>.</p>
<p>Followed the <a href="http://www.elasticsearch.org/tutorials/2011/07/18/attachment-type-in-action.html" rel="noreferrer">Attachment Type in Action tutorial</a> but the process hangs and <strong>I don't know how to interpret the error message</strong>. Also tried the <a href="https://gist.github.com/1075067" rel="noreferrer">gist</a> which hangs in the same place.</p>
<pre><code>$ curl -X POST "localhost:9200/test/attachment/" -d json.file
{"error":"ElasticSearchParseException[Failed to derive xcontent from (offset=0, length=9): [106, 115, 111, 110, 46, 102, 105, 108, 101]]","status":400}
</code></pre>
<p>More details:</p>
<p>The <code>json.file</code> contains an embedded Base64 PDF file (as per instructions). The first line of the file <em>appears</em> correct (to me anyway): <code>{"file":"JVBERi0xLjQNJeLjz9MNCjE1OCAwIG9iaiA8</code>...</p>
<p>I'm not sure if maybe the <code>json.file</code> is invalid or if maybe elasticsearch just isn't set up to parse PDFs properly?!?</p>
<p><strong>Encoding</strong> - Here's how we're encoding the PDF into <code>json.file</code> (as per tutorial):</p>
<pre><code>coded=`cat fn6742.pdf | perl -MMIME::Base64 -ne 'print encode_base64($_)'`
json="{\"file\":\"${coded}\"}"

<p>How can I access the items in the dict to print a list of my projects as in the HTML above the test?</p>
<p>I solved my own problem with help from <a href="https://stackoverflow.com/questions/19141073/rendering-a-python-dict-in-jinja2-werkzeug">Rendering a python dict in Jinja2 / Werkzeug</a>
The template block should be </p>

{% endfor %}
</code></pre>
<p>But I'm still curious as to how to access further nested dictionaries, and if this is the smartest way to create a simple menu.</p>

Android Location.distanceBetween and Location.distanceTo difference
|
<p>I encounter some issues on trying to calculate distance between one location and a list of others (in order to get the closest one).
I tried by using Location.distanceBetween(...) and location.distanceTo(...), the two method are working but both of them send me different data and not any of them seems right.</p>
<p>My data came from a Class ConcessionDistance which is a basic extension of HashMap containing location data (as integer convert as string) and some other stuff that we don't need here.</p>
<pre><code>private ArrayList<ConcessionDistance> getMapsConcessionsDistancesFromPoint(ArrayList<ConcessionDistance> al, Location currentLocation) {
Location dest;
float distance1,distance2;
float[] curDist = new float[1];
double lati,longi;
Log.i("DBTableConcessions","getMapsConcessionsDistancesFromPoint: Generation d'une map de donnée de concession");
for(ConcessionDistance curConc : al){
//Distance by method 1
dest = new Location(LOCATION_PROVIDER);
lati = new Double((new Integer(curConc.get("concession_latitude"))) /1e6);
longi = new Double((new Integer(curConc.get("concession_longitude"))) /1e6);
dest.setLatitude(lati);
dest.setLongitude(longi);
distance1 = currentLocation.distanceTo(dest);
//Distance by method2
Location.distanceBetween(
currentLocation.getLatitude(),
currentLocation.getLongitude(),
(double) ((new Integer(curConc.get("concession_latitude"))) /1000000),
(double) ((new Integer(curConc.get("concession_longitude"))) /1000000),
curDist);
distance2 = curDist[0];
Log.i("DBTableConcessions","distance :"+distance1+" ou "+distance2);//+" ,lat :"+lati+" ,long "+longi); //+"curDist{0="+curDist[0]+",1="+curDist[1]+",2="+curDist[2]+"}"
//Saving one of the distance
curConc.put("distance",String.valueOf(distance1));
}
return al;
}
</code></pre>
<p>Can some one help me, to figure out where is the problem?
I think of a conversion problem but I'm to deep in the problem to solve it myself :(</p>
<p>Any help will be welcome. Thanks by advance.</p>
<p><b>Edit</b>: Here is part of my LogCat: I send to the emulator the gps location of "Strasbourg" (those are cities from east-france) and process distance to all those cities:</p>

</code></pre>
<p>The real distance (given by google maps) between those cities and <b>"Strasbourg"</b> are :<br/>
<b>Evry</b> : 520km ( method1 : miss 175km, method2 : miss 145km)<br/>
<b>Haguenau</b> : 30km ( method1: add 70km, method2: return 0)<br/>
<b>Besancon</b> : 250km (method1: miss 140km, method2: miss 120km)<br/>
<b>Brest</b> : 1070km (method1: miss 200km, method2: miss 230km)<br/>
<b>Hoenheim</b> : 5km (method1: add 80km, method2: return 0)<br/>
<b>Colmar</b> : 75km (method1: miss 50km, method2: return 0)<br/>
<b>Belfort</b> : 155km (method1: miss 110km, method2: miss 20km)<br/>
<b>Sarrebourg</b> : 75km (method1: miss 5km, method2: return 0)<br/></p>
<p>So we can notice that the second method return 0 when real distance is below ~100km, wherease for the method1 I can't see any logic inhere :/</p>

scale_colour_gradient(low="#00FF33", high ="#FF0000")+
labs(colour="T", size="P")+
xlab("x") + ylab("y")+
# ylim(0,3000)+
scale_size(range = c(3, 8)) +
theme_bw(base_size = 12, base_family = "Helvetica") +
theme(panel.grid.minor = element_line(colour="grey", size=0.5)) +
theme(axis.text.x = element_text(angle = 45, hjust = 1))
print(gg3)
</code></pre>
<p>It is quite what I want but I would like to have the legend below the plot with an horizontal direction and the legend title on the top of the legend. I kind of managed to put the legend below the plot by adding this command line <code>theme(legend.position="bottom", legend.direction="horizontal")</code>. However, I could not really manage to achieve to put the legend title on top of the legend. Does anyone know how I could do it?</p>

How to render a partial view (using razor) after user click?
|
<p>I've been searching for a solution, but every thing I tried didn't help, although it seems very easy. I'm sure some of you will know what should I do.</p>
<p>I am using ASP.NET MVC4 (razor).
I have a side menu, and all I want is that another partial view will be rendered (depends on the menu item's being clicked).
I have a div on my page that should contain this partial view. The command: </p>
<pre><code> @Html.Partial("_TitleDescription")
</code></pre>
<p>works just fine, but it's statically render the partial view (on compilation time). I want it to render it dynamically with every button the user clicked in the menu.</p>
<p>I tried:</p>
<pre><code> @Ajax.ActionLink("Location", "Location", "Product", new { id = @Model.ID }, new AjaxOptions() { UpdateTargetId = "result", InsertionMode = InsertionMode.Replace, HttpMethod = "GET"})
</code></pre>
<p>I tried:</p>
<pre><code> <script type="text/javascript">
function getView() {
$('#detailsDiv').load("@Url.Action("Location" , "Product" )");
}
</script>
<a href='javascript:getView();'>Get Partial View</a>
<div id="detailsDiv"></div>
</code></pre>
<p>and also like this:</p>
<pre><code> <div id="detailsDiv">
@{ Html.RenderPartial("_TitleDescription", null); }
</div>
</code></pre>
<p>but nothing works for me.</p>
<hr>
<p>EDIT:</p>
<p>I tried the two answers but non of them works... so here is my controller:</p>
<pre><code> public ActionResult Location(int id = 0)
{
Product product = unitOfWork.ProductRepository.GetById(id);
return PartialView("Location.cshtml", product);
}
</code></pre>
<p>I put a breakpoint and I'm hitting it every time, but still nothing is changing in the view... :(</p>
<p>This is what i tried again:</p>
<pre><code> <div id="detailsDiv"></div>
<a href="#" onclick="loadLocation()">Location</a>
<script type="text/javascript">
function loadLocation() {
$.get('@Url.Action("Location","Product", new { id = 15 } )',
function (data) {
$('#detailsDiv').load(data);
});
}
</script>
</code></pre>
<p>and I also tried this:</p>
<pre><code> <div id="detailsDiv"></div>
@Html.ActionLink("Pages","Location","Product",new {id = 15},new {@class="menu"})
<script type="text/javascript">
$(function () {
$(".menu").click(function (e) {
e.preventDefault();
$("#detailsDiv").load($(this).attr("href"))
});
});
</script>

Is async HttpClient from .Net 4.5 a bad choice for intensive load applications?
|
<p>I recently created a simple application for testing the HTTP call throughput that can be generated in an asynchronous manner vs a classical multithreaded approach.</p>
<p>The application is a able to perform a predefined number of HTTP calls and at the end it displays the total time needed to perform them. During my tests, all HTTP calls were made to my local IIS sever and they retrieved a small text file (12 bytes in size).</p>
<p>The most important part of the code for the asynchronous implementation is listed below:</p>
<pre><code>public async void TestAsync()
{
this.TestInit();
HttpClient httpClient = new HttpClient();
for (int i = 0; i < NUMBER_OF_REQUESTS; i++)
{
ProcessUrlAsync(httpClient);
}
}
private async void ProcessUrlAsync(HttpClient httpClient)
{
HttpResponseMessage httpResponse = null;
try
{
Task<HttpResponseMessage> getTask = httpClient.GetAsync(URL);
httpResponse = await getTask;
Interlocked.Increment(ref _successfulCalls);
}
catch (Exception ex)
{
Interlocked.Increment(ref _failedCalls);
}
finally
{
if(httpResponse != null) httpResponse.Dispose();
}
lock (_syncLock)
{
_itemsLeft--;
if (_itemsLeft == 0)
{
_utcEndTime = DateTime.UtcNow;
this.DisplayTestResults();
}
}
}
</code></pre>
<p>The most important part of the multithreading implementation is listed below:</p>
<pre><code>public void TestParallel2()
{
this.TestInit();
ServicePointManager.DefaultConnectionLimit = 100;
for (int i = 0; i < NUMBER_OF_REQUESTS; i++)
{
Task.Run(() =>
{
try
{
this.PerformWebRequestGet();
Interlocked.Increment(ref _successfulCalls);
}
catch (Exception ex)
{
Interlocked.Increment(ref _failedCalls);
}
lock (_syncLock)
{
_itemsLeft--;
if (_itemsLeft == 0)
{
_utcEndTime = DateTime.UtcNow;
this.DisplayTestResults();
}
}
});
}
}
private void PerformWebRequestGet()
{
HttpWebRequest request = null;
HttpWebResponse response = null;
try
{
request = (HttpWebRequest)WebRequest.Create(URL);
request.Method = "GET";
request.KeepAlive = true;
response = (HttpWebResponse)request.GetResponse();
}
finally
{
if (response != null) response.Close();
}
}
</code></pre>
<p>Running the tests revealed that the multithreaded version was faster. It took it around 0.6 seconds to complete for 10k requests, while the async one took around 2 seconds to complete for the same amount of load. This was a bit of a surprise, because I was expecting the async one to be faster. Maybe it was because of the fact that my HTTP calls were very fast. In a real world scenario, where the server should perform a more meaningful operation and where there should also be some network latency, the results might be reversed.</p>
<p>However, what really concerns me is the way HttpClient behaves when the load is increased. Since it takes it around 2 seconds to deliver 10k messages, I thought it would take it around 20 seconds to deliver 10 times the number of messages, but running the test showed that it needs around 50 seconds to deliver the 100k messages. Furthermore, it usually takes it more than 2 minutes to deliver 200k messages and often, a few thousands of them (3-4k) fail with the following exception:</p>
<blockquote>
<p>An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.</p>
</blockquote>
<p>I checked the IIS logs and operations that failed never got to the server. They failed within the client. I ran the tests on a Windows 7 machine with the default range of ephemeral ports of 49152 to 65535. Running netstat showed that around 5-6k ports were being used during tests, so in theory there should have been many more available. If the lack of ports was indeed the cause of the exceptions it means that either netstat didn't properly report the situation or HttClient only uses a maximum number of ports after which it starts throwing exceptions.</p>
<p>By contrast, the multithread approach of generating HTTP calls behaved very predictable. I took it around 0.6 seconds for 10k messages, around 5.5 seconds for 100k messages and as expected around 55 seconds for 1 million messages. None of the messages failed. Further more, while it ran, it never used more than 55 MB of RAM (according to Windows Task Manager). The memory used when sending messages asynchronously grew proportionally with the load. It used around 500 MB of RAM during the 200k messages tests.</p>
<p>I think there are two main reasons for the above results. The first one is that HttpClient seems to be very greedy in creating new connections with the server. The high number of used ports reported by netstat means that it probably doesn't benefit much from HTTP keep-alive.</p>
<p>The second is that HttpClient doesn't seem to have a throttling mechanism. In fact this seems to be a general problem related to async operations. If you need to perform a very large number of operations they will all be started at once and then their continuations will be executed as they are available. In theory this should be ok, because in async operations the load is on external systems but as proved above this is not entirely the case. Having a big number of requests started at once will increase the memory usage and slow down the entire execution.</p>
<p>I managed to obtain better results, memory and execution time wise, by limiting the maximum number of asynchronous requests with a simple but primitive delay mechanism:</p>
<pre><code>public async void TestAsyncWithDelay()
{
this.TestInit();
HttpClient httpClient = new HttpClient();
for (int i = 0; i < NUMBER_OF_REQUESTS; i++)
{
if (_activeRequestsCount >= MAX_CONCURENT_REQUESTS)
await Task.Delay(DELAY_TIME);
ProcessUrlAsyncWithReqCount(httpClient);
}
}
</code></pre>
<p>It would be really useful if HttpClient included a mechanism for limiting the number of concurrent requests. When using the Task class (which is based on the .Net thread pool) throttling is automatically achieved by limiting the number of concurrent threads.</p>
<p>For a complete overview, I have also created a version of the async test based on HttpWebRequest rather than HttpClient and managed to obtain much better results. For a start, it allows setting a limit on the number of concurrent connections (with ServicePointManager.DefaultConnectionLimit or via config), which means that it never ran out of ports and never failed on any request (HttpClient, by default, is based on HttpWebRequest, but it seems to ignore the connection limit setting).</p>
<p>The async HttpWebRequest approach was still about 50 - 60% slower than the multithreading one, but it was predictable and reliable. The only downside to it was that it used a huge amount of memory under big load. For example it needed around 1.6 GB for sending 1 million requests. By limiting the number of concurrent requests (like I did above for HttpClient) I managed to reduce the used memory to just 20 MB and obtain an execution time just 10% slower than the multithreading approach.</p>
<p>After this lengthy presentation, my questions are: Is the HttpClient class from .Net 4.5 a bad choice for intensive load applications? Is there any way to throttle it, which should fix the problems I mention about? How about the async flavor of HttpWebRequest?</p>
<p><strong>Update (thanks @Stephen Cleary)</strong></p>
<p>As it turns out, HttpClient, just like HttpWebRequest (on which it is based by default), can have its number of concurrent connections on the same host limited with ServicePointManager.DefaultConnectionLimit. The strange thing is that according to <a href="http://msdn.microsoft.com/en-us/library/system.net.servicepointmanager.defaultconnectionlimit.aspx" rel="noreferrer">MSDN</a>, the default value for the connection limit is 2. I also checked that on my side using the debugger which pointed that indeed 2 is the default value. However, it seems that unless explicitly setting a value to ServicePointManager.DefaultConnectionLimit, the default value will be ignored. Since I didn't explicitly set a value for it during my HttpClient tests I thought it was ignored.</p>
<p>After setting ServicePointManager.DefaultConnectionLimit to 100 HttpClient became reliable and predictable (netstat confirms that only 100 ports are used). It is still slower than async HttpWebRequest (by about 40%), but strangely, it uses less memory. For the test which involves 1 million requests, it used a maximum of 550 MB, compared to 1.6 GB in the async HttpWebRequest.</p>
<p>So, while HttpClient in combination ServicePointManager.DefaultConnectionLimit seem to ensure reliability (at least for the scenario where all the calls are being made towards the same host), it still looks like its performance is negatively impacted by the lack of a proper throttling mechanism. Something that would limit the concurrent number of requests to a configurable value and put the rest in a queue would make it much more suitable for high scalability scenarios.</p>

why do I get 'inject' undefined error when using Jasmine with Angular?
|
<p>I am Jasmine/AngularJS unit testing newbie. I created a simple angular app to add two numbers so that I can learn how to write unit tests for Angular App. The <a href="http://docs.angularjs.org/guide/dev_guide.unit-testing#!" rel="noreferrer">Angular Doc on unit test is incomplete</a>.Based on the blogs and stack overflow answers, I build my first test and I am running into 'injector' undefined error. I am using Jasmine framework for the unit testing. <br>
<strong>HTML</strong></p>
<pre><code><body>
<div ng-controller="additionCtrl">
First Number: <input ng-model="NumberOne"/><br/>
Second Number: <input ng-model="NumberTwo"/>
<button ng-click="add(NumberOne, NumberTwo)">Add</button><br/>
Result: {{Result}}

<pre><code>function additionCtrl($scope) {
$scope.NumberOne = 0;
$scope.NumberTwo = 0;

<p>This is a failing test and once the test fails with the expected result then I can modify the code to make it pass, but I am facing the problem with somehow angular mock is not getting injector. <br>
I saw an example where I can newup a controller instead of using injector, but I would like to try to learn on using injector so that I am set up more complex tests.<br> I might be missing something simple here. Please direct me to any write up I might have missed.<br>

No plugin found for prefix 'exec' in the current project and in the plug in groups org.codehaus.mojo

<p>I have read several questions with similar issue and the Help 1 page. Unfortunately, I am stuck. </p>
<p>One possible reason could be caused by proxy but there is no such proxy here. Additionally, all maven projects in my PC have been successfully updated when I update it from Eclipse. So I discard this possibility. </p>
<p>Other thing I checked was to look for codehaus in my local repository and I find it (C:\Users\myUser.m2\repository\org\codehaus\mojo). </p>

error TS5023: Unknown compiler option 'enableIvy'

<p>I am trying to add IVY to my angular 7 beta project. So, I added <code>enableIvy: true</code> to <code>src/tsconfig.app.json</code> in <code>compilerOptions</code> section</p>
<p>But when I run <code>ng build --prod --aot --output-hashing none</code> I get below error.</p>

Visual Studio 2012 Web Deploy Publish ignores selected Configuration for transform and build
|
<p>When I create a publish profile I have the option to select which Configuration I want the publish to use for this profile. The options are like Debug, Release or any custom defined one like Staging.
The problem is that if I select any Configuration other than Release or Debug, say Staging, visual studio totally ignores my selection and uses Web.Release.config for transform and build.
Am I doing something wrong or is this by design? It seems that Publish only recognizes Release and Debug as acceptable Configuration. Any thoughts on this issue?</p>
<p>I am using Visual Studio 2012 RTM. </p>
<p><strong>Update 1 :: "NightlyLive - Any CPU" configuration selected:</strong></p>
<p>Here I select my own custom Configuration "NightlyLive":</p>
<p><img src="https://i.stack.imgur.com/tlGpv.png" alt="enter image description here"></p>
<p>And here is what happens when I publish:</p>
<pre><code>6>------ Build started: Project: UI.Next, Configuration: Release Any CPU ------
7>------ Publish started: Project: UI.Next, Configuration: Release Any CPU ------
7>Transformed Web.config using [...]\UI.Next\Web.Release.config into obj\Release\TransformWebConfig\transformed\Web.config.
</code></pre>
<p>As you can see it builds the project using Release Any CPU (instead of NightlyLive - Any CPU) and also it transforms the Web.config using Web.Release.config (instead of Web.NightlyLive.config).</p>
<p><strong>Update 2 :: Profile name renamed to "NightlyLive":</strong></p>
<p>Here i rename the profile name from "test" to "NightlyLive". </p>
<p><img src="https://i.stack.imgur.com/denan.png" alt="enter image description here"></p>
<p>Here is the console output:</p>
<pre><code>6>------ Build started: Project: UI.Next, Configuration: Release Any CPU ------
7>------ Publish started: Project: UI.Next, Configuration: Release Any CPU ------
7>Transformed Web.config using [...]\UI.Next\Web.Release.config into obj\Release\TransformWebConfig\transformed\Web.config.
7>[...]\UI.Next\Web.NightlyLive.config(23,18): Warning : Argument 'debug' did not match any attributes
7>[...]\UI.Next\obj\Release\TransformWebConfig\transformed\Web.config(78,6): Warning : No attributes found to remove
7>Transformed obj\Release\TransformWebConfig\transformed\Web.config using [...]\UI.Next\\Web.NightlyLive.config into obj\Release\ProfileTransformWebConfig\transformed\Web.config.
</code></pre>
<p>So here, still it is building using Release Any CPU. </p>
<p>But for Web.config it first transforms using Web.Release.config then it does a second transformation on top of the previous one using Web.NightlyLive.config.</p>
<p>The double transformation i think is by design and makes sense. But the fact that you have to rename your profile name to the configuration name to force use your custom transformation file, does not look right.</p>
<p><strong>Update 3 :: TestSolution added</strong></p>
<p>You can download the stripped down solution from <a href="http://sdrv.ms/OSJNcS" rel="noreferrer">here</a>.</p>
<p>First I created a brand new vs2012 solution and everything worked fine. So I decided to strip down my current solution and upload as test case. </p>
<p><em>Please note that my solution was originally a vs2010 solution that i opened in vs2012 and vs2012 did the necessary modifications to the solution.</em> </p>
<p><strong>Update 4 :: Verdict</strong></p>
<p>I guess my solution configurations were all messed up. So basically to solve this issue, I deleted all my customized solution and project configurations and created them again along with the web.config transform files.</p>
<p><strong>Problem solved.</strong></p>

C OpenMP parallel quickSort
|
<p>Once again I'm stuck when using openMP in C++. This time I'm trying to implement a parallel quicksort.</p>
<p><strong>Code:</strong></p>
<pre><code>#include <iostream>
#include <vector>
#include <stack>
#include <utility>
#include <omp.h>
#include <stdio.h>
#define SWITCH_LIMIT 1000
using namespace std;
template <typename T>
void insertionSort(std::vector<T> &v, int q, int r)
{
int key, i;
for(int j = q + 1; j <= r; ++j)
{
key = v[j];
i = j - 1;
while( i >= q && v[i] > key )
{
v[i+1] = v[i];
--i;
}
v[i+1] = key;
}
}
stack<pair<int,int> > s;
template <typename T>
void qs(vector<T> &v, int q, int r)
{
T pivot;
int i = q - 1, j = r;
//switch to insertion sort for small data
if(r - q < SWITCH_LIMIT)
{
insertionSort(v, q, r);
return;
}
pivot = v[r];
while(true)
{
while(v[++i] < pivot);
while(v[--j] > pivot);
if(i >= j) break;
std::swap(v[i], v[j]);
}
std::swap(v[i], v[r]);
#pragma omp critical
{
s.push(make_pair(q, i - 1));
s.push(make_pair(i + 1, r));
}
}
int main()
{
int n, x;
int numThreads = 4, numBusyThreads = 0;
bool *idle = new bool[numThreads];
for(int i = 0; i < numThreads; ++i)
idle[i] = true;
pair<int, int> p;
vector<int> v;
cin >> n;
for(int i = 0; i < n; ++i)
{
cin >> x;
v.push_back(x);
}
cout << v.size() << endl;
s.push(make_pair(0, v.size()));
#pragma omp parallel shared(s, v, idle, numThreads, numBusyThreads, p)
{
bool done = false;
while(!done)
{
int id = omp_get_thread_num();
#pragma omp critical
{
if(s.empty() == false && numBusyThreads < numThreads)
{
++numBusyThreads;
//the current thread is not idle anymore
//it will get the interval [q, r] from stack
//and run qs on it
idle[id] = false;
p = s.top();
s.pop();
}
if(numBusyThreads == 0)
{
done = true;
}
}
if(idle[id] == false)
{
qs(v, p.first, p.second);
idle[id] = true;
#pragma omp critical
--numBusyThreads;
}
}
}
return 0;
}
</code></pre>
<p><strong>Algorithm:</strong></p>
<p>To use openMP for a recursive function I used a stack to keep track of the next intervals on which the qs function should run. I manually add the 1st interval [0, size] and then let the threads get to work when a new interval is added in the stack.</p>
<p><strong>The problem:</strong></p>
<p>The program ends too early, not sorting the array after creating the 1st set of intervals ([q, i - 1], [i+1, r] if you look on the code. My guess is that the threads which get the work, considers the local variables of the quicksort function(qs in the code) shared by default, so they mess them up and add no interval in the stack.</p>
<p><strong>How I compile:</strong></p>
<pre><code>g++ -o qs qs.cc -Wall -fopenmp
</code></pre>
<p><strong>How I run:</strong></p>
<p><code>./qs < in_100000 > out_100000</code></p>
<p>where in_100000 is a file containing 100000 on the 1st line followed by 100k intergers on the next line separated by spaces.</p>
<p>I am using gcc 4.5.2 on linux</p>
<p>Thank you for your help,</p>
<p>Dan </p>

<p>And I want :</p>

</blockquote>
<p>The criteria to filter is get the min and max "Qty" from table and get only the first value when exists duplicate "Qty" values in the same "Unit" and "client" column.</p>
<p>I do the follow T-SQL, but the retrieval is the last "Qty" value when the "Unit" and "client" column are the same, I need the first.</p>
<pre><code> --1

Aggregating Rows Pandas
|
<p>I am quite new to <code>pandas</code>. I need to aggregate <code>'Names'</code> if they have the same name and then make an average for <code>'Rating'</code> and <code>'NumsHelpful'</code> (without counting <code>NaN</code>). <code>'Review'</code> should get concatenated whilst <code>'Weight(Pounds)'</code>should remain untouched: </p>
<pre><code>col names: ['Brand', 'Name', 'NumsHelpful', 'Rating', 'Weight(Pounds)', 'Review']
Name 'Brand' 'Name'
1534 Zing Zang Zing Zang Bloody Mary Mix, 32 fl oz
1535 Zing Zang Zing Zang Bloody Mary Mix, 32 fl oz
1536 Zing Zang Zing Zang Bloody Mary Mix, 32 fl oz
1537 Zing Zang Zing Zang Bloody Mary Mix, 32 fl oz
1538 Zing Zang Zing Zang Bloody Mary Mix, 32 fl oz
1539 Zing Zang Zing Zang Bloody Mary Mix, 32 fl oz
1540 Zing Zang Zing Zang Bloody Mary Mix, 32 fl oz
'NumsHelpful' 'Rating' 'Weight'
1534 NaN 2 4.5
1535 NaN 2 4.5
1536 NaN NaN 4.5
1537 NaN NaN 4.5
1538 2 NaN 4.5
1539 3 5 4.5
1540 5 NaN 4.5
'Review'
1534 Yummy - Delish
1535 The best Bloody Mary mix! - The best Bloody Ma...
1536 Best Taste by far - I've tried several if not ...
1537 Best bloody mary mix ever - This is also good ...
1538 Outstanding - Has a small kick to it but very ...
1539 OMG! So Good! - Spicy, terrific Bloody Mary mix!
1540 Good stuff - This is the best
</code></pre>
<p>So the output should be something like this:</p>
<pre><code> 'Brand' 'Name' 'NumsHelpful' 'Rating'
Zing Zang Zing Zang Bloody Mary Mix, 32 fl oz 3.33 3
'Weight' 'Review'
4.5 Review1 / Review2 / ... / ReviewN
</code></pre>
<p>How shall I procede? Thanks.</p>

The method getApplicationContext() is undefined - fragment issues

<p>I am getting the following errors:
The method getApplicationContext() is undefined
The method findViewById(int) is undefined for the type Fragment1</p>
<p>These errors seem to be eliminated when my class is extended to an Activity as oppose to a fragment, but it is important that this activity remains as a fragment, so I am not too sure how to work this out.</p>

HTTP Error 500.35 - ANCM Multiple In-Process Applications in same Process ASP.NET Core 3
|
<p>From this morning without any changes to the code of the project, a very simple Web API, one controller and 3 methods, with Swagger, it doesn't start anymore and I get the error:</p>
<blockquote>
<p>HTTP Error 500.35 - ANCM Multiple In-Process Applications in same Process</p>
</blockquote>
<p>Event viewer report the most useless message:</p>
<blockquote>
<p>IIS Express AspNetCore Module V2: Failed to start application
'/LM/W3SVC/2/ROOT/docs', ErrorCode '0x80004005'.</p>
</blockquote>
<p>Restarted the system several times.</p>
<p>I'm using Visual Studio 2019, the application successfully compile and a few minutes ago it was working fine. No new software has been installed, no packages added.
Tried also clean and rebuild.</p>
<p>I've just modified the comment of a method. Obviously I've tried also to restore the previous comment but I get always the same message.</p>
<p>What can I do?</p>
<p>Is net core still too unstable to be used professionally?</p>
<p><strong>UPDATE</strong></p>
<p>The same code launched from the same version of Visual Studio but in another PC runs properly.</p>
<p><strong>UPDATE 2</strong></p>
<p>Below the code of the application:</p>
<p>startup.cs</p>

<p>but coping the project on another PC with the same Visual Studio version works fine, so it looks like the is a configuration bug in the .NET Core or VIsual Studio property...</p>

Rspec doesn't see my model Class. uninitialized constant error
|
<p>I'm writing tests on Rspec for my models in Ruby on Rails application.
And I receive this error while starting 'rspec spec' </p>
<pre><code>command:
/spec/models/client_spec.rb:4:in `<top (required)>': uninitialized constant Client (NameError)
</code></pre>
<p>I use Rails 4.0.0 and Ruby 2.0.0</p>
<p>Here is my client_spec.rb:</p>
<pre><code>require 'spec_helper'
describe Client do
it 'is invalid without first_name', :focus => true do
client = Client.new
client.should_not be_valid
end
end
</code></pre>
<p>And Gemfile:</p>
<pre><code>source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.0.rc1'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.0.rc1'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'
# gem 'therubyracer', platforms: :ruby
# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more:

<p>And at last client.rb (ROR Model and Class):</p>
<pre><code>class Client < ActiveRecord::Base

has_one :client_status
has_one :discount_plan, through: :client_status

</code></pre>
<p>If it'd be useful my spec_helper.rb file:</p>
<pre><code># This file was generated by the `rspec --init` command. Conventionally, all

Rendering HTML+Javascript server-side
|
<p>I need to render an HTML page server-side and "extract" the raw bytes of a canvas element so I can save it to a PNG. Problem is, the canvas element is created from javascript (I'm using jquery's Flot to generate a chart, basically). So I guess I need a way to "host" the DOM+Javascript functionality from a browser without actually using the browser. I settled on mshtml (but open to any and all suggestions) as it seems that it should be able to to exactly that. This is an ASP.NET MVC project. </p>
<p>I've searched far and wide and haven't seen anything conclusive. </p>
<p>So I have this simple HTML - example kept as simple as possible to demonstrate the problem - </p>
<pre><code><!DOCTYPE html>
<html>
<head>
<title>Wow</title>
<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.7.1.min.js" type="text/javascript"></script>
</head>
<body>
<div id="hello">
</div>
<script type="text/javascript">
function simple()
{
$("#hello").append("<p>Hello</p>");
}
</script>
</body>
</html>
</code></pre>
<p>which produces the expected output when run from a browser. </p>
<p>I want to be able to load the original HTML into memory, execute the javascript function, then manipulate the final DOM tree. I cannot use any System.Windows.WebBrowser-like class, as my code needs to run in a service environment. </p>
<p>So here's my code:</p>
<pre><code>IHTMLDocument2 domRoot = (IHTMLDocument2)new HTMLDocument();
using (WebClient wc = new WebClient())
{
using (var stream = new StreamReader(wc.OpenRead((string)url)))
{
string html = stream.ReadToEnd();
domRoot.write(html);
domRoot.close();
}
}
while (domRoot.readyState != "complete")
Thread.Sleep(SleepTime);
string beforeScript = domRoot.body.outerHTML;
IHTMLWindow2 parentWin = domRoot.parentWindow;
parentWin.execScript("simple");
while (domRoot.readyState != "complete")
Thread.Sleep(SleepTime);
string afterScript = domRoot.body.outerHTML;
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(domRoot);
domRoot = null;
</code></pre>
<p>The problem is, "beforeScript" and "afterScript" are exactly the same. The IHTMLDocument2 instance goes through the normal "uninitialized", "loading", "complete" cycle, no errors are thrown, nothing.</p>
<p>Anybody have any ideas on what I'm doing wrong? Completely lost here. </p>

<p>My whole project has stuck in between. As I have not created the tool so not sure where exactly is the error occurring... and this error(even <code>gdb</code>) is not giving any hint regarding where is the problem.How to detect the point of error?</p>
<p>I am giving some snapshots of the problem if they help. Please guide me how should I proceed? It's looking like a mesh to me.</p>

<p>It's an open source tool sendip and I am trying to generate ipsec traffic. If any code portion will be required I will add it here but don't have time to report the bug and wait for it to be fixed because acc. to the tool specifications i choose it for my purpose and now I am completely stuck in between. Please guide me for this.</p>
<p>I know it's almost impossible to tell what is the error and where it is without even looking at the code. I am just asking for your help and suggestion what should I do in this situation because its not even completely my mistake.</p>
<p><strong>If anyone could tell me any tool which could tell me where exactly is the problem ????</strong></p>
<p>I am not even sure whether the question is suitable for here; if not please tell me where to migrate it?</p>
<p>As suggested I tried with <code>valgrind</code>. I never even heard about it before so no idea how to proceed with here is the output. Please guide me how to go about it further?</p>
