Authentication Pages spec with valid information tests failing
|
<p>I am following Michael Hart'l RoR Tutorial but seem to have a problem getting the authentication_pages test "with valid information" to pass in chapter 8.</p>
<p>Specifically, the test complains that the relevant links are missing from the page, even though when I actually visit the page, they are there just fine. In fact, even when I hard these links into every page, the tests complain that the relevant links are not present.</p>
<p>The tests are below: the failing ones are the ones 'with valid information' - everything apart from the it { should have_title(user.name) }</p>
<pre><code> require 'spec_helper'
describe "AuthenticationPages" do
subject {page}
describe "signin page" do
before {visit signin_path}
it {should have_content("Sign in")}
it {should have_title("Sign in")}
describe "with invalid information" do
before {click_button('Sign in')}
it {should have_title('Sign in')}
it {should have_selector("div.alert.alert-error", text: "Invalid")}
describe "after visiting another page" do
before {click_link "Home"}
it {should_not have_selector("div.alert.alert-error", text: "Invalid")}
end
end
**describe "with valid information" do
let(:user) { FactoryGirl.create(:user) }
before do
fill_in "Email", with: user.email.upcase
fill_in "Password", with: user.password
click_button "Sign in"
end
it { should have_title(user.name) }
it { should have_link('Profile', href: user_path(user)) }
it { should have_link('Sign out', href: signout_path) }
it { should_not have_link('Sign in', href: signin_path) }
it { should have_content('This is the user page')}**
end
end
end

useState updating for all list elements

<p><a href="https://i.stack.imgur.com/Q5oVp.png" rel="nofollow noreferrer">After clicking on picture</a></p>
<p>So I used useState to play with margins and make a description slide down div which initially hides behind the image itself. I am using map() to diplay a list of images with the same properties. But the useState works fine when using a single image. For multiple images clicking o 1 image activates the slidedown div for all the images. I want them to be seperate. Is there any solution to this?</p>

How to speed up the deletion of entries from a table with a large number of entries
|
<p>I have a table that currently has over 150 million records. The table has no foreign keys.</p>
<p><a href="https://i.stack.imgur.com/s7VOR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/s7VOR.png" alt="[TABLE]" /></a></p>
<p>The database was previously based on MySQL and was migrated to SQL Server.
Since then, one specific query on that table has taken much, much longer.
On MySQL, the query counterpart took less than 3 seconds to execute. On SQL Server, the query can be executed even for more than 1 minute.</p>
<p>There is no problem with any other table or query at the moment - just this one on this one table.</p>
<p>[EXAMPLE] : I CAN'T CHANGE A QUERY.</p>
<pre><code>delete from Features WITH(ROWLOCK)

Toggling TableColumn.setVisible resets width, setPrefWidth doesn't change it
|
<p>I have a TableView full of nested columns. On these columns, I have 2 context menu options -- "Hide Column" and "Unhide All Columns", which toggle the visibility of the columns and their children as such.</p>
<p>The tableview is populated after the UI is initialized, so the size of the columns is set to the default width, which is smaller than the size of the longest cell value. This is what I want to happen. I don't want the columns to extend to thousands of pixels wide because of a single particularly long entry.</p>
<p>My problem is this: <strong>when the user hides the column and unhides it, the width of that column stretches out to the smallest length possible to fit the longest cell value. This is not what I want to happen.</strong> I want it to ideally keep its original width when the visibility is toggled in this way.</p>
<p>To solve this, I tried setting the max width to the current width before I hide the column, and then unsetting the max width and setting the prefwidth to the former maxwidth after I unhide it (thus locking it from resizing itself). This doesn't work.</p>
<p>Here's an example to show what's happening.</p>

<p>Here's what the happens when I hide/unhide the name column: <a href="https://i.stack.imgur.com/3M9C4.gif" rel="nofollow noreferrer">example (animated gif)</a></p>
<p>Here's the output:</p>
<pre><code>width to set to: 80.0
current prefwidth: 80.0
current actual width: 80.0
</code></pre>
<p>...which is of course not what the seems to shown, as the width is clearly longer than 80.0 after un-hiding! This happens for all of the columns, including the "colors" parent column (in that case both color1 and color2 columns extend to the width of the longest cell value string).</p>
<p>Another twist: the code actually does work <em>if the user makes sure to resize the column they're hiding before they hide it</em>. <a href="https://i.stack.imgur.com/XKl3j.gif" rel="nofollow noreferrer">Example (animated gif)</a>.</p>
<p><strong>So, what's going on? Obviously the application is extending the columns to fit the longest data after the visibility is set to true. How can I make sure that the columns maintain their former lengths? Why does it only work after the user has resized that column (if it's setting a flag somewhere maybe I can set that flag manually?)</strong></p>

ImageView inside listview getting changed on search refresh

<p>I have a <code>listview</code> which contains <code>TextView</code> and <code>ImageView</code>.</p>
<p>Here it is: </p>
<p><img src="https://i.stack.imgur.com/T3BCA.png" alt="enter image description here"> </p>
<p><code>OnClick</code> of <code>ImageView</code> changes opens an <code>alertdialog</code> with buttons Yes and No.</p>
<p><img src="https://i.stack.imgur.com/szd7m.png" alt="enter image description here"></p>
<p>if press Yes</p>
<p><code>imageView</code> changes its background to blue, </p>
<p>if press no, </p>
<p><code>imageView</code> background changes to red.</p>
<p><img src="https://i.stack.imgur.com/t933S.png" alt="enter image description here"></p>
<p>Till now it is working fine. </p>
<p>I have a search <code>edittext</code> above the <code>listview</code>, which searches based on the <code>textview</code> in the <code>listview</code>. </p>

<p><img src="https://i.stack.imgur.com/sIooM.png" alt="enter image description here"></p>
<p>What should I do to make the <code>imageview</code> show the image which was selected in the alert dialog.</p>

<p>I tried the following so far</p>
<pre><code>apple_merged = pd.merged(df_1, df_lookup, left_on = ["BB", "CC"], right_on = ["XX", "YY"])
df_1[(df_1["AA"] == "Apple")]["DD"] = apple_merged[(apple_merged.AA == "Apple")]["ZZ"].values
</code></pre>
<p>I got the following error in my actual code:</p>
<blockquote>
<p>ValueError: Length of values (501) does not match length of index
(602)</p>
</blockquote>
<p>Which seems to suggest that the shape of the data is different on the opposite side of the assignment, 501 v/s 602. But if I really did left join, should the row counts not be the same for me in this case?</p>

Running chrome extension process while popup is closed
|
<p>Basically I am trying to create an Auto Visitor Extension for Chrome to open a website's URL after some specific time. When I open the popup everything works fine but when the popup is close nothing works. I am trying to find out a method to run that Auto Visitor Extension even when the popup is close I have read multiple questions regarding this phenomena on Stack Overflow but none of them clarifies what I am looking for.</p>
<p>Here is my manifest file:</p>
<p><strong>manifest.json</strong></p>
<pre><code>{
"manifest_version": 2,
"name": "Auto Visitor",
"description": "This extension will visit multiple pages you saved in extension",
"version": "1.0",
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html"
},
"background": {
"scripts": [
"background.js"
],
"persistent": false
},
"permissions": [
"activeTab",
"storage",
"tabs",
"http://*/",
"https://*/"
]
}
</code></pre>
<p>The background file that i want to run even when popup is close :</p>
<p><strong>background.js</strong></p>
<pre><code>// this will work only when you denie the background script in manifest
chrome.runtime.onInstalled.addListener(function(details) {
var initTime = 5;
chrome.storage.local.set({"avtime": initTime}, function() {});
});
reloadMainTab();
function reloadMainTab() {
chrome.storage.local.get('avurl', function (result) {
var urlsToLoad = result.avurl;
console.log(urlsToLoad);
if(urlsToLoad==undefined){
// do nothing
}else{
var urlsArr = urlsToLoad.split(",");
chrome.storage.local.get('avtime', function (result) {
var thisTime = result.avtime;
/*
setting it to -1 because it gets incremented by 1
when it goes into getSelected method
*/
var index=-1;
setInterval(function(){
if(index < urlsArr.length-1){
chrome.tabs.getSelected(function (tab) {
// console.log('index in get selected'+index)
chrome.tabs.update(tab.id,{url: urlsArr[index]});
});
index++;
}else{
index=-1;
}
}, thisTime+"000");
});
}
});
}

<p>any help would be really appreciated</p>

My onActivityResult() is never called
|
<p>I have 2 Activities, Parent Activity starts Child Activity. When we are in Child Activity, the User closes it via the "Up"-Button in the menu and is returned to Parent Activity.</p>
<p>Essential code snippets:</p>
<p><strong>Parent (Main) Activity:</strong></p>
<pre class="lang-java prettyprint-override"><code>protected static final int TIMERCHOOSER_REQUEST = 1;
</code></pre>
<p>starting new Activity (called from a menu button):</p>
<pre class="lang-java prettyprint-override"><code>private void openTimerChooser() {
Intent intent = new Intent(this, TimerChooserActivity.class);
startActivityForResult(intent,TIMERCHOOSER_REQUEST);
}
</code></pre>
<p>and for fetching the result:</p>
<pre class="lang-java prettyprint-override"><code>@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode,resultCode,data);
Log.d("Main", "called onActivityResult"); //this and below is never executed
if (requestCode == TIMERCHOOSER_REQUEST) {
switch(resultCode) {
case RESULT_CANCELED:
Log.d("Main", "Intent result was canceled by TIMERCHOOSER");
case RESULT_OK:
//code to handle data from TIMERCHOOSER_REQUEST
Log.d("Main", "accepted resultCode. value: "+resultCode);
String result = data.getStringExtra("result");
Toast toast = Toast.makeText(getApplicationContext(),result,Toast.LENGTH_SHORT);
toast.show();
default:
Log.d("Main", "invalid/unhandled resultCode? value: "+resultCode);
}
}
else
Log.d("Main", "invalid/unhandled requestCode? value: "+requestCode);
}
</code></pre>
<p><strong>Child Activity ("TimerChooserActivity"):</strong></p>
<pre class="lang-java prettyprint-override"><code>@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
switch(id) {
case R.id.action_settings:
return true;
case android.R.id.home:
Log.d("TimerChooser", "finishing intent");
Intent returnIntent = new Intent();
returnIntent.putExtra("result", "Some result");
/*if(result == "User activated textview")
setResult(RESULT_OK,returnIntent);
else
setResult(RESULT_CANCELED,returnIntent);*/
setResult(RESULT_OK,returnIntent);
finish();
default:
return super.onOptionsItemSelected(item);
}
}
</code></pre>
<p>You get back to the Parent(Maint) Activity via the home/up button in the menu / action bar. This works. But <code>onActivityResult()</code> is never called, no matter what kind of result I set.</p>
<p>There's no weird tag in my manifest, too. Just standard stuff:</p>
<pre><code>android:allowBackup
android:icon
android:label
android:theme
android:name
android:parentActivityName
android:value
</code></pre>
<p>What's going on?</p>

RestKit 0.20 NSArray serialization problems
|
<p>I'm trying to serialize an NSArray of objects.</p>
<p>The object serializes as:</p>
<pre><code>{"age":1,"name":"Foo"}
</code></pre>
<p>If I have an NSArray Containing these objects, it should serialize as:</p>
<pre><code>[{"age":1,"name":"Bob"},{"age":4,"name":"Sally"},{"age":2,"name":"Jill"}]
</code></pre>
<p>However, when I serialize it directly via RestKit, I get the following:</p>
<pre><code>{"age":[1,3,2],"name":["Sally","Jack","Bob"]}
</code></pre>
<p>When I inspect the RKMIMETypeSerialization, I see the following: (which would match the json output)</p>
<pre><code>Parameters: {
age = (
1,
3,
2
);
name = (
Sally,
Jack,
Bob
);
}
</code></pre>
<p>I'm sure that I'm just doing something really silly, I have been playing with it can't figure it out.</p>
<p>Here is my mapping logic</p>
<pre><code>+ (RKObjectMapping *)mapping {
RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[Item class]];
[mapping addAttributeMappingsFromDictionary:@{
@"name" : @"name",
@"age" : @"age"
}];
return mapping;
}
</code></pre>
<p>And here is the logic doing the array serialization:</p>
<pre><code>+ (NSString *)JSONStringFromArray:(NSArray *)array {
RKObjectMapping *mapping = [Item mapping];
RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:mapping.inverseMapping objectClass:[Item class] rootKeyPath:nil];
NSError *error;
NSDictionary *parameters = [RKObjectParameterization parametersWithObject:array requestDescriptor:requestDescriptor error:&error];
// Serialize the object to JSON
NSData *JSON = [RKMIMETypeSerialization dataFromObject:parameters MIMEType:RKMIMETypeJSON error:&error];
NSString *jsonString = [[NSString alloc] initWithBytes:[JSON bytes]
length:[JSON length] encoding:NSUTF8StringEncoding];
return jsonString;
}
</code></pre>
<p>Here are test classes:
<strong>Item.h</strong></p>
<pre><code>#import <Foundation/Foundation.h>
@interface Item : NSObject
@property(nonatomic, strong) NSString *name;
@property(nonatomic) int age;

@end
</code></pre>
<p><strong>Item.m</strong></p>

Item *item = [[Item alloc] init];
item.name = name;

return item;
}
@end
</code></pre>
<p><strong>To execute</strong>
Have RestKit pod installed and then issue the following:</p>
<pre><code> [Item testJsonSerialization];
[Item testJsonArraySerialization];
</code></pre>
<p>Note, maybe I'm not configuring the mapping correctly for the array serialization. Though this mapper works perfectly for deserializing the targeted json text up above.</p>

Starting a Service in an AlertDialog and have an outside Activity bound to it
|
<p>First of all I've tried searching for this ans was unsuccessful. If my question is out there already answered could someone please point me to it? Thank you very much for either helping me here by looking at this, or even by skimming this and pointing me in the right direction. I really do appreciate it!</p>
<p><strong>My dilemma:</strong> I have an activity, and in that activity there is listview. The listview has multiple items inside it that most need to call an AlertDialog. The AlertDialog calls a service that says, "Hey, you need to update some data." The Service listens and does the update successfully. </p>
<p>The problem that comes into play is that my activity doesn't acknowledge the service. What I'm wondering about is that I'm don't fully understand how a Service operates, and if you can have the same service spun up / running more than once.</p>
<p>Note, my example ties somewhat to the idea on <a href="http://developer.android.com/reference/android/app/Service.html" rel="nofollow">The Android Dev Reference for Service</a>.</p>

// class name because we want a specific service implementation that
// we know will be running in our own process (and thus won't be
// supporting component replacement by other applications).

_isBound= true;

<p>DescriptionDialog truncated (constructor), Also, this is extended from the AlertDialog.Builder class. I also have a class that is common in all dialogs where basically I store the _context. So in the case here, the context is saved in the super. The _context is protected ...</p>
<pre><code>public ChangeDescriptionDialog(Context context)
{
super(context);
DialogInterface.OnClickListener onClickListenerPositive = new DialogInterface.OnClickListener()

public void onClick(DialogInterface dialog, int id)

//dispatch change
Intent ChangeItems = new Intent("ChangeItems");
Bundle extras = new Bundle();
extras.putParcelable(BundleLocations.BUNDLE_ITEM, _description);
extras.putString(BundleLocations.ACTION, _action);
ChangeItems.putExtras(extras);
//
// my question is partly here
// I start this service...
//
// How would my activity see it... right now it doesn't seem that way even though I do the binding before this call
//
_context.startService(ChangeItems);
}
};
this.setPositiveButton(context.getResources().getString(R.string.DIALOG_POS), onClickListenerPositive);
}
</code></pre>
<p>Again, notice the binding that takes place before the popup occurs. 2nd, notice me starting the service in the binding. What am I doing wrong or just not getting?</p>
<p>Thank you all again,

Heroku Scheduler: undefined local variable or method `params' for CreditsController:Class
|
<p>I am trying to automate a task with Heroku Scheduler. I tested the task in local and it works. I created a temporary route for testing, and it works everytime I hit the route:</p>
<pre><code>get 'create_expired_credit_lines' to: 'credits#create_expired_lines'
</code></pre>
<p>credits.controller.rb</p>
<pre><code>class CreditsController < ApplicationController
...
def self.create_expired_lines
...
@new_credit = Credit.new(params[:credit])
...
end
</code></pre>
<p>I then created a file </p>
<pre><code>app/lib/tasks/scheduler.rake
desc "This task is called by the Heroku scheduler add-on"
task :create_expired_credit_lines => :environment do
puts "Creating expired credit lines..."
CreditsController.create_expired_lines
puts "done."
end
</code></pre>
<p>When the tasks get executed, I get the following error:</p>
<pre><code>2014-03-20T21:42:11.190318+00:00 app[scheduler.4496]: undefined local variable or method `params' for CreditsController:Class

<p>===========</p>
<p>UPDATE:
I removed the arguments from the method Credit.new(params[:credit]) and it now looks like this:</p>
<p>credits.controller.rb</p>
<pre><code>class CreditsController < ApplicationController

def new
...
@credit = Credit.new
@credit.user_id = params[:id]

@new_credit = Credit.new(params[:credit])

end

<p>When I run the command </p>
<pre><code>$ heroku run rake create_expired_credit_lines
</code></pre>
<p>I get the following errors:</p>

SAPUI5 Reusable Table Fragment Data Binding
|
<p>I am starting to develop SAPUI5, trying to apply concepts and best practices from other web dev toolkits I know so far, please be kind as my knowledge is still fairly limited.</p>
<p>I want to re-structure a project and replace copy-paste code with reusable parts. Custom controls are not the right way as far as I checked, basically it is purely standard functionality of a SAPUI5 control with different data binding.
The data binding and propagation should be done via XML as it fits the project architecture best, my initial idea was to use fragments.</p>
<p>Sample:
An identical table should be used multiple times in the same view and in different views, single model with different object arrays.</p>
<p>Fragment:</p>
<pre><code> <Table items="{???}">
<columns>
<Column >
<Text text="Name"/>
</Column>
<Column>
<Text text="Amount"/>
</Column>
</columns>
<items>
<ColumnListItem>
<cells>
<ObjectIdentifier title="{dataModel>name}"/>
<Text text="{dataModel>amount}"/>
</cells>
</ColumnListItem>
</items>
</Table>
</core:FragmentDefinition>
</code></pre>
<p>Model:</p>
<pre><code>let oTemp = new JSONModel({
data: {
a: [{
name: "Product 1 Entry 1",
amount: "Product 1 Amount 1"
}, {
name: "Product 1 Entry 2",
amount: "Product 1 Amount 2"
}],
b: [{
name: "Product 2 Entry 1",
amount: "Product 2 Amount 1"
}, {
name: "Product 2 Entry 2",
amount: "Product 2 Amount 2"
}]
}
});
this.getView().setModel(oTemp, "dataModel");
</code></pre>
<p>XML View Usage:</p>
<pre><code><core:Fragment objectBindings="dataModel>/data/a" type="XML" fragmentName="...view.ReusableTable"></core:Fragment>
<core:Fragment objectBindings="dataModel>/data/b" type="XML" fragmentName="...view.ReusableTable"></core:Fragment>
</code></pre>
<p>I tried various ways to bind the item aggregation in the table or the fragment itself, without success.
As hopefully shown in this sample, I want to pass a specific model property to the fragment and its table to display a different set of items (a or b) without the use of javascript in the view controller.</p>
<p>Desired Output:</p>
<p>2 Tables, identical header (Name, Amount column) with 2 rows each using data from datamodel, property a [] and b []</p>
<p>From what I saw in the SAPUI5 library offering regarding code reuse, fragments should be the best way to achieve this result as no additional controller logic is required to display | interact. I would appreciate any suggestions how to approach this, or maybe change the approach in general if necessary? Thank you lots!</p>

symfony contact form is submitted but emails dont arrive

<p>I need some help regarding sending emails in symfony 4.</p>
<p>I made a contact form in symfony 4.
where i use formbuilder and swiftmailer. The contact form works, it validates and i can submit. but emails don't arrive plus i don't get a confirmation message on the contactpage itself after sending.
i use mailer with host of the website itself. The website is in production mode.</p>
<p>See below the code i used. Maybe i missed some settings? thanks in advance!</p>
<p>ContactType.php</p>

<p>and in my <em>main.env</em> file i have this</p>
<pre><code>MAILER_URL=smtp://localhost:25?encryption=ssl&auth_mode=login&username=xxx&password=xxxx
</code></pre>
<p>So email does not get delivered. After submit I am transferred back to contact page, and no flash message either :/
Have I missed anything else for this to work?</p>
<p><strong><em>example:</em></strong> </p>
<ul>
<li>does my username have to be a whole email address that I also need to decode, etc?</li>
<li>do I need to change something on the server also? please advise.</li>

jQuery fullcalendar doesn't update database after resizing
|
<p>Ola,</p>
<p>I got some events stored in a database and i'm showing these in my jquery fullcalendar. Now i also got it working so that i can change the day of an event by draging and dropping. Changing the time by resizing a event i can't get working tho.</p>
<p>I guess it has something to do with me not giving a time here:</p>
<pre><code>start = moment(start, 'DD.MM.YYYY').format('YYYY-MM-DD')
end = moment(end, 'DD.MM.YYYY').format('YYYY-MM-DD')
</code></pre>
<p>But all the formats i tried (for instance: YYYY-MM-DDThh:mm:ss) give this error:</p>
<pre><code>Uncaught ReferenceError: start is not defined
</code></pre>
<p>Now with my current code i <strong>can</strong> resize elements, it only doesn't save them in my database. This is the code:</p>
<pre><code>$(document).ready(function() {
var calendar = $('#calendar').fullCalendar({
editable: true,
events: "http://localhost/plann/events.php",
defaultView: 'agendaWeek',
selectable: true,
editable: true,
selectHelper: true,
select: function(start, end, allDay) {
var title = prompt('Event Title:');
if (title) {
start = moment(start, 'DD.MM.YYYY').format('YYYY-MM-DD')
end = moment(end, 'DD.MM.YYYY').format('YYYY-MM-DD')
$.ajax({
url: 'http://localhost/plann/add_events.php',
data: 'title='+ title+'&start='+ start +'&end='+ end ,
type: "POST",
success: function(json) {
alert('OK');
}
});
calendar.fullCalendar('renderEvent',
{
title: title,
start: start,
end: end,
allDay: allDay
},
true // make the event "stick"
);
}
calendar.fullCalendar('unselect');
},
eventDrop: function(event, delta) {
start = moment(event.start, 'DD.MM.YYYY').format('YYYY-MM-DD')
end = moment(event.end, 'DD.MM.YYYY').format('YYYY-MM-DD')
$.ajax({
url: 'http://localhost/plann/update_events.php',
data: 'title='+ event.title+'&start='+ start +'&end='+ end +'&id='+ event.id ,
type: "POST",
success: function(json) {
alert("OK");
}
});
},
eventResize: function(event) {
start = moment(event.start, 'DD.MM.YYYY').format('YYYY-MM-DD')
end = moment(event.end, 'DD.MM.YYYY').format('YYYY-MM-DD')
$.ajax({
url: 'http://localhost/plann/update_events.php',
data: 'title='+ event.title+'&start='+ start +'&end='+ end +'&id='+ event.id ,
type: "POST",
success: function(json) {

}
});

Fix RegEx to properly capture text inside parenthesis
|
<h2>SCENARIO</h2>
<hr>
<p>Time ago I asked a question to format music filenames in certain conditions:</p>
<ul>
<li><a href="https://stackoverflow.com/questions/32807698/regex-pattern-to-limit-dashes-in-these-circumstances">RegEx pattern to limit dashes in these circumstances</a></li>
</ul>
<p>However, I noticed too late that the accepted answer is wrong, because it can capture any word starting with "F". But this is not a problem/question, I solved it just by restoring the <code>ft|feat|featuring</code> OR group.</p>
<p>So finally from que question linked above, I ended up using this expression:</p>
<pre><code>pattern := '^(.+)\s+-\s+(.+?)\s+(ft|feat|featuring)[\.\s]*([^([\])]+)(.+)?$'
replace := '$1 Feat. $4 - $2$5'
</code></pre>
<p>Well, now, having these filenames to test:</p>
<ol>
<li>Black Coast - Trndsttr</li>
<li>Black Coast - Trndsttr (Feather)</li>
<li>Black Coast - Trndsttr (Lucian Remix)</li>
<li>Black Coast - Trndsttr (Feather) (Lucian Remix)</li>
<li>Black Coast - Trndsttr Feat. M. Maggie</li>
<li>Black Coast - Trndsttr (Feat. M. Maggie)</li>
<li>Black Coast - Trndsttr Feat. M. Maggie (Lucian Remix)</li>
<li>Black Coast - Trndsttr (Feat. M. Maggie) (Lucian Remix)</li>
<li>Black Coast - Trndsttr (Lucian Remix) Feat. M. Maggie</li>
<li>Black Coast - Trndsttr (Lucian Remix) (Feat. M. Maggie)</li>
<li>Black Coast - Trndsttr (Feather) (Lucian Remix) Feat. M. Maggie</li>
<li>Black Coast - Trndsttr (Feather) (Lucian Remix) (Feat. M. Maggie)</li>
<li>Black Coast - Trndsttr (Feather) Feat. M. Maggie (Lucian Remix)</li>
<li>Black Coast - Trndsttr (Feather) (Feat. M. Maggie) (Lucian Remix) </li>
<li>Black Coast - Trndsttr (Feather) (Feat. M. Maggie) Lucian Remix</li>
<li>Black Coast - Trndsttr (Feather) Feat. M. Maggie Lucian Remix</li>
</ol>
<p>The expected results are these:</p>
<p>(from 1 to 4 no changes, and 16 is an assumable false positive, it is in essence the same as 5, 9 and 11.)</p>
<ol>
<li>Black Coast - Trndsttr</li>
<li>Black Coast - Trndsttr (Feather)</li>
<li>Black Coast - Trndsttr (Lucian Remix)</li>
<li>Black Coast - Trndsttr (Feather) (Lucian Remix)</li>
<li>Black Coast Feat. M. Maggie - Trndsttr</li>
<li>Black Coast Feat. M. Maggie - Trndsttr</li>
<li>Black Coast Feat. M. Maggie - Trndsttr (Lucian Remix)</li>
<li>Black Coast Feat. M. Maggie - Trndsttr (Lucian Remix)</li>
<li>Black Coast Feat. M. Maggie - Trndsttr (Lucian Remix)</li>
<li>Black Coast Feat. M. Maggie - Trndsttr (Lucian Remix)</li>
<li>Black Coast Feat. M. Maggie - Trndsttr (Feather) (Lucian Remix)</li>
<li>Black Coast Feat. M. Maggie - Trndsttr (Feather) (Lucian Remix)</li>
<li>Black Coast Feat. M. Maggie - Trndsttr (Feather) (Lucian Remix)</li>
<li>Black Coast Feat. M. Maggie - Trndsttr (Feather) (Lucian Remix)</li>
<li>Black Coast Feat. M. Maggie - Trndsttr (Feather) Lucian Remix</li>
<li>Black Coast Feat. M. Maggie Lucian Remix - Trndsttr (Feather) </li>
</ol>
<h2>PROBLEM</h2>
<hr>
<p>The expression that I mentioned works perfect for all the filenames except for the cases where the <strong>Feat...</strong> part is grouped inside parenthesis (or brackets, whatever).</p>
<p>Then I tried to adapt the RegEx for the aggrupations condition:</p>
<pre><code>pattern := '^(.+)\s+-\s+(.+?)\s+([\[\(\{])?\s*(ft|feat|featuring([\.])?\s+)((.+)[^\]\)\}])?\s*(.+)?$'
</code></pre>
<p>But I ended messing my head and missing things, because it also captures the first parenthesis enclosure and the following characters till the end.</p>
<p>I need some help with this.</p>
<h2>Question</h2>
<hr>
<p>How I could fix/improve my expression to treat the mentioned filenames to get the expected results above?.</p>
<p>Or in other words, I need to maintain the "structure" of the expression but adding the capability to capture the <strong>Feat...</strong> part when it is inside parenthesis/brackets to properly format the filename.</p>
<p>PS: Please remember that I'm under pascal-script's RegEx syntax and their limitations (which I'm not sure about them).</p>
<h2>IMPORTANT EDIT:</h2>
<p>I discovered that the author of the software that has this limitations it has support to run an external app from its pascal-script editor, so I can launch a CLI app written in .Net to perform the regex replacement, then I'm now under C#/Vb.Net RegEx motor improvements, nice!.</p>

Call a PHP File with AJAX

<p>I have been looking at other questions and based my code out of the corresponding answers, but I can't seem to make this work. I would appreciate if someone more experienced than me can help me see clearer on this one.</p>
<p><strong>jQuery:</strong></p>
<pre><code>$(function () {
$(".going-decision").click(function () {
var clickBtnValue = $(this).val();
alert('clicked');
$.ajax({

<p>My HTML buttons do have the class 'going-decision'. jQuery library is included.</p>
<p><strong>Result:</strong> The 'clicked' alert is displaying, along with the 'success' one. However, the database is not updated.</p>

Why is my browser preventing me from submitting empty fields ? Symfony
|
<p>I made a form that allows users to register.</p>
<p>There is one question that asks what language they want to learn. In order to make the question optional I created the new field type to my User entity in Terminal and I specified that it can be <strong>null</strong>.</p>
<p>But, when I validate the form without answering the optional question, I have this displayed error message : <strong>Please select a valid language.</strong></p>
<p>Thank you for your help.</p>

python mysql query not displaying correct result

<p>I have a code here and it's supposed to show all results where the selection from combobox like id = the value in the entry box. But when the code is executed I get a empty set "[]", it skips to the if statement which gives me a messagebox, despite the fact that the database is populated and it's displaying properly with the other function that I have defined before. Is there a mistake in my code or am I doing anything wrong here?</p>

How To Apply Regex in Shiny App Filter/Button?
|
<p>I'm super new to Shiny Apps and to R. How would I add a button that allows me to filter the passed-in dataset using this regex? The uploaded dataset would all contain the same column names, and the column I want to apply the regex to is "close_notes". I want to first <strong>convert this column to a string, uppercase everything, then apply the regex</strong>. Thank you so much for your help in advance!</p>
<p>The Regular Expression:</p>
<p><code>"\\bMASTER DATA\\b|\\bSOURCE LIST\\b|\\bVALIDITY DATES\\b|\\bMRP CONTROLLER\\b|\\bPSV\\b|\\bELIGIBILITY\\b|\\bCOST\\b|\\bMARKETING EXCLUSION\\b|\\bEFFECTIVITY\\b|\\bMISSING\\b|\bbBLANK\\b"</code></p>
<p>The code below is for the Shiny App. Please let me know if anything looks wrong or like it should be modified. Thank you!</p>
<pre><code>library(shiny)

Recursive custom thumbnail for embedded YouTube API won't replay
|
<p>I have an embedded YouTube video, but I want to use my own custom image for the face (thumbnail) of the video before <strong>and after</strong> the video plays. I have it working successfully up to where it shows the custom image in place of the video, and when the image is clicked, the image is removed and the video is loaded and played. Once the video is complete, the image is restored back to what appears to be the video's ready-to-play state. </p>
<p>However, once the image is clicked again to replay the video, the video won't play again. I was hoping that every time my playYouTubeVideo() function is called from the click event listener, that the YT.Player object would reset and load again, but this isn't working. </p>
<p>Any help you can give would be appreciated.</p>
<p>The stackoverflow snippet I created as a demo doesn't actually play the YouTube embed, and you kind of need to be able to see the video end to know what I mean, so I've included and link to a fiddle as well:</p>

<p>I'm using C#, Visual Studio 2008, Framework 2.0 for embedded device.</p>
<p>I'm having trouble with the use of a Socket connection to communicate with FTPs.</p>
<p>In the purpose of you guys to help me, I wrote a snippet to explain my troubles...</p>
<pre><code> IPEndPoint endpoint;
Socket cmdsocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPAddress address = IPAddress.Parse(args[0]);
endpoint = new IPEndPoint(address, int.Parse(args[1]));
// Connection
cmdsocket.Connect(endpoint);
if (cmdsocket.Connected)
{
do
{
Console.WriteLine("Type the command to send : ");
string l_sCommandToSend = Console.ReadLine();
Console.WriteLine("Do you want a timeout to receive ? (Y/N (default))");
string l_sReceiveTimeout = Console.ReadLine();
// Sending
byte[] bytes = Encoding.ASCII.GetBytes((l_sCommandToSend + "\r\n").ToCharArray());
cmdsocket.Send(bytes, bytes.Length, 0);
if (l_sReceiveTimeout == "Y")
{
Thread.Sleep(1000);
}
// Receiving
byte[] bufferToRead = new byte[512];
string l_sResponsetext = "";
int l_iByteReceivedCount = 0;
while (cmdsocket.Available > 0)
{
Console.WriteLine("Receiving...");
l_iByteReceivedCount = cmdsocket.Receive(bufferToRead, SocketFlags.None);
l_sResponsetext += Encoding.ASCII.GetString(bufferToRead, 0, l_iByteReceivedCount);
Console.WriteLine("Bytes Received : " + l_iByteReceivedCount);
Console.WriteLine("l_sResponsetext : " + l_sResponsetext);
}
Console.WriteLine("This is the answer : " + l_sResponsetext);
} while (true);
}
Console.WriteLine("Job done.");
Console.ReadLine();
// Fermeture du socket
cmdsocket.Close();
cmdsocket = null;
</code></pre>
<p>Above is a snippet that :</p>
<ul>
<li>Connect to a FTP (I'm using FileZilla Server for tests purposes on my server side)</li>
<li>Asks the user which command he wants to send</li>
<li>Asks the user if he wants a Sleep between send and receive (More details later)</li>
<li>Reads and displays the answer.</li>
</ul>
<p>I noticed that if I do not use a Sleep between a FTP command and the response, sometimes I don't get a correct response (empty string).
For example, sending the command "USER Andy" will result in the response "" when no Sleep is set. When the sleep is set to 1 second, I do get the proper answer which is "331 Password required for Andy".</p>
<p>I tried to debug my Socket without talking to a FTP and chose a software like Hercules. Everything is working as expected, my Receive method call just hangs 'til it receives an answer.</p>
<p>What am I doing wrong here ?</p>

How do I use a ListView tool to list my activity classes in Eclipse (Android) within an activity?
|
<p>I am making an app that shows a list of campfire songs, and currently all I can see on my app is a list of all the songs and when clicked on, they open up another activity. The next activity that is opened looks how I want it to, but the list of songs on the first activity (menu) only shows a list with no formatting around it or any images or buttons that I have specified in the XML. - I haven't linked these up in the code as they stop the list from appearing at all.</p>
<p>Here is my Java file for Menu.java:</p>
<pre><code>package com.lmarshall1995.scoutsongs;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class Menu extends ListActivity{
String classes[] = {"......"};
String items[] = {"......"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(Menu.this, android.R.layout.simple_list_item_1, items));
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
String song_activity = classes[position];
try{
Class<?> ourClass = Class.forName("com.lmarshall1995.scoutsongs." + song_activity);
Intent ourIntent = new Intent(Menu.this, ourClass);
startActivity(ourIntent);
}catch(ClassNotFoundException e){
e.printStackTrace();
}
}
}
</code></pre>
<p>And here is my XML file for menu.xml that I would like the list to be put in (@+id/list):</p>
<pre><code><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" xmlns:app="http://schemas.android.com/apk/lib/com.google.ads">
<TextView

android:textSize="20sp" />
<ListView
android:id="@android:id/list"
android:layout_width="wrap_content"
android:layout_height="320dp"
android:layout_below="@+id/ic_launcher"
tools:listitem="@android:layout/simple_list_item_1" >
</ListView>
<ImageView
android:id="@+id/ic_launcher"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:contentDescription="@string/ic_launcher"
android:src="@drawable/ic_launcher" />
<ImageButton
android:id="@+id/settings_button"
android:src="@drawable/settings_button_selected"
android:contentDescription="@string/action_settings"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true" />
<ImageButton
android:id="@+id/exit_button"
android:src="@drawable/exit_button_selected"
android:contentDescription="@string/exit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true" />
</RelativeLayout>
</code></pre>
<p>I was wondering if someone could help me turn what I think is the android.R.layout.simple_list_item_1 into my list (@+id/list) from my menu.xml file. Any suggestions?
Thanks,

Retain fragment data on screen rotation
|
<p>I have 3 fragments where 1 fragment makes changes to the other 2.</p>
<p>The problem is: When I rotate the screen background color and places of fragments 2 and 3 are restored.
I want to keep them without modifying <code>AndroidManifest.xml</code>.
Is it best to use onSaveInstanceState or setRetainInstance or both?</p>
<p>I found some other answers about retaining fragments but none of them were beneficial for my case.</p>
<p><strong>FirstFragment</strong></p>

Button btn = v.findViewById(R.id.button_replace);
buttonOk.setOnClickListener(v1 -> mCallBack.changeColor(R.color.black));
btn.setOnClickListener(v12 -> {
clickCheck = !clickCheck;

Construct count array in better than O(n^2) time complexity
|
<p>Given an array <code>A[]</code> of size <code>n</code>, construct two arrays <code>C_min[]</code> and <code>C_max[]</code> such that<br>
<code>C_min[i]</code> represents number of elements smaller than <code>A[i]</code> in <code>A[0 to i]</code> and<br>
<code>C_max[i]</code> represents number of elements greater than <code>A[i]</code> in <code>A[i to n-1]</code> </p>
<p>For example <code>A[5] = {1,2,4,3,6}</code> then <code>C_min[]</code> and <code>C_max[]</code> would be<br>
<code>C_min[5] = {0,1,2,2,4}</code><br>
<code>C_max[5] = {4,3,1,1,0}</code></p>
<p>I am not able to think of an algorithm better than O(n^2) but <a href="http://www.geeksforgeeks.org/counting-inversions/" rel="nofollow">this post</a> motivates me to think of some better way of doing this, but am not able to able apply similar kind of logic(which is mentioned in the post) here. </p>
<p>In the given post, problem given is to find no of inversion in an array. if array[i] > array[j] and j>i then it forms a inversion. for example The sequence 2, 4, 1, 3, 5 has three inversions (2, 1), (4, 1), (4, 3).<br>
idea used to solve this problem is a merge sort algorithm.<br></p>
<blockquote>
<p>In merge process, let i is used for indexing left sub-array(L[]) and j
for right sub-array(R[]). At any step in merge(), if L[i] is greater
than R[j], then there are (mid – i+1) inversions,where mid is the
middle index passed to the merge function of merge sort. because left
and right subarrays are sorted, so all the remaining elements in
left-subarray (L[i+1], L[i+2] … L[mid]) will be greater than R[j]</p>
</blockquote>
<p>code for this logic is given below:</p>
<pre><code>#include <bits/stdc++.h>
int _mergeSort(int arr[], int temp[], int left, int right);
int merge(int arr[], int temp[], int left, int mid, int right);
/* This function sorts the input array and returns the
number of inversions in the array */
int mergeSort(int arr[], int array_size)
{
int *temp = (int *)malloc(sizeof(int)*array_size);
return _mergeSort(arr, temp, 0, array_size - 1);
}
/* An auxiliary recursive function that sorts the input array and
returns the number of inversions in the array. */
int _mergeSort(int arr[], int temp[], int left, int right)
{
int mid, inv_count = 0;
if (right > left)
{
/* Divide the array into two parts and call _mergeSortAndCountInv()
for each of the parts */
mid = (right + left)/2;
/* Inversion count will be sum of inversions in left-part, right-part
and number of inversions in merging */
inv_count = _mergeSort(arr, temp, left, mid);
inv_count += _mergeSort(arr, temp, mid+1, right);
/*Merge the two parts*/
inv_count += merge(arr, temp, left, mid+1, right);
}
return inv_count;
}
/* This funt merges two sorted arrays and returns inversion count in
the arrays.*/
int merge(int arr[], int temp[], int left, int mid, int right)
{
int i, j, k;
int inv_count = 0;
i = left; /* i is index for left subarray*/
j = mid; /* i is index for right subarray*/
k = left; /* i is index for resultant merged subarray*/
while ((i <= mid - 1) && (j <= right))
{
if (arr[i] <= arr[j])
{
temp[k++] = arr[i++];
}
else
{
temp[k++] = arr[j++];
/*this is tricky -- see above explanation/diagram for merge()*/
inv_count = inv_count + (mid - i);
}
}
/* Copy the remaining elements of left subarray
(if there are any) to temp*/
while (i <= mid - 1)
temp[k++] = arr[i++];
/* Copy the remaining elements of right subarray
(if there are any) to temp*/
while (j <= right)
temp[k++] = arr[j++];
/*Copy back the merged elements to original array*/
for (i=left; i <= right; i++)
arr[i] = temp[i];
return inv_count;
}
/* Driver progra to test above functions */
int main(int argv, char** args)
{
int arr[] = {1, 20, 6, 4, 5};
printf(" Number of inversions are %d \n", mergeSort(arr, 5));
getchar();
return 0;
}
</code></pre>
<p>so can this count array problem be done on similar lines.</p>

<p>Is it possible to construct count array in better than O(n^2)-time?</p>

How to make my menu items do something?

Getting information out of a listbox windows phone 8
|
<p>i'm currently developing an app for windows phone 8, that grabs JSON data from the internet, parses it into a collection, binds this collection to a listbox and shows it. This works fine, and i do it like this:</p>
<pre><code>void downloadData()
{
// Instance of a WebClient object
WebClient downloader = new WebClient();
// EventHandler for download String completed
downloader.DownloadStringCompleted += new DownloadStringCompletedEventHandler(downloaded);
// AsyncDownloading of the Websitecontent and Encoding in UTF8
downloader.Encoding = Encoding.UTF8;
downloader.DownloadStringAsync(new Uri("http://scm1.hensgen.net:8181/cxf/plugins/mandantenmonitor/rs/list", UriKind.Absolute));
}
void downloaded(object sender, DownloadStringCompletedEventArgs e)
{
// tests wheter string is empty or not downloaded completely
if (e.Result == null || e.Error != null)
{
MessageBox.Show("Error occured while downloading JSON-file from server");
}
else
{
// Deserialize if downloaded succeedes
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(MandantenListeRoot));
// Reads the e.Result string and writes it in UTF8 encoded into a MemoryStream and Cast it from type object to MandantenListeRoot
MandantenListeRoot root = serializer.ReadObject(new MemoryStream(Encoding.UTF8.GetBytes(e.Result))) as MandantenListeRoot;
MandantenListe mandListe = root.mandantenListeDataMember;
// Bind the downloaded Collection to our MandantenListBox-control Panel
mandantenListeBox.ItemsSource = mandListe.MandantenCollection;
}
}
</code></pre>
<p>I want to parse and ID attribute of this collection to the next page in my up when i click on one list entry.
Now i read about this a bunch on the tubes and if i understand it correctly i should simply be able to cast the sender object in the MouseButtonDown method and pass it onto the next page like this</p>
<pre><code> private void MandantenStackPanel_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
//MandantenListeMandant mandant = (sender as Button).DataContext as MandantenListeMandant
// PhoneApplicationService.Current.State["MandantenNummer"] = mandant.MandantenNummer;
NavigationService.Navigate(new Uri("/Vorlagen.xaml", UriKind.Relative));
}
</code></pre>
<p>This does not seem work and if i read the debug information i get correctly the sender object is -1. The relevant XAML for my page looks like this:</p>
<pre><code> <ListBox x:Name="mandantenListeBox" Margin="0,0,0,0">
<ListBox.ItemTemplate>
<DataTemplate >
<StackPanel Margin="0,10,0,10" Width="455" MouseLeftButtonDown="MandantenStackPanel_MouseLeftButtonDown">
<TextBlock Text="{Binding MandantenNummer}" FontSize="24" TextWrapping="Wrap"/>
<TextBlock Text="{Binding MandantenBezeichnung}" FontSize="24" TextWrapping="Wrap"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</code></pre>
<p>Thank you for your help, i really appreciate it.</p>

Latest compiler versions and GLIBC_2.32 dependency
|
<ul>
<li><p>When I compile my library with <strong>GCC 11</strong> or <strong>Clang 12</strong> I get a GLIBC_2.32 dependency.</p>
</li>
<li><p>When I compile the same library with the same arguments but with older version compilers (<strong>GCC 10</strong>, <strong>Clang 11</strong>) I don't get the GLIBC_2.32 dependency.</p>
</li>
</ul>
<p>Is there a way to get rid of this dependency on newer versions of compilers?</p>

<p>I created a force layout around a circle in d3js (<a href="https://stackoverflow.com/questions/22439832/d3-js-how-do-i-arrange-nodes-of-a-force-layout-to-be-on-a-circle">D3.js how do I arrange nodes of a force layout to be on a circle</a>) and now I want to put the labels around like this:</p>
<p><a href="https://i.stack.imgur.com/4Hcw2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4Hcw2.png" alt="enter image description here"></a></p>

Django Form Date Input Field Not Showing Errors
|
<p>I have a form on a registration page that requires a date to be entered, along with a few other fields. If the user enters non-valid information into the date field (like a string) and submits the form, Django rejects the form as non-valid, but I don't get any error messages on the page - But for the other fields on the form, I do get error messages (ex: Passwords Don't Match, User Already Registered, etc).</p>
<p>Here is what the form looks like:
<a href="https://i.stack.imgur.com/FLWvE.png" rel="nofollow noreferrer">Link to image of registration form</a></p>
<p>Here is my <strong>forms.py</strong> file - I'm using two classes to create the form on the registration page:</p>
<pre class="lang-py prettyprint-override"><code>from django import forms
from users.models import Profile
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm
class CustomUserCreationForm(UserCreationForm):
email = forms.EmailField(required=True)
class Meta(UserCreationForm.Meta):
model = User
#fields = UserCreationForm.Meta.fields + ("email",)
fields = ['username', 'email', 'password1', 'password2']
class EmployeeForm(forms.ModelForm):
hireDate = forms.DateField(
required=False,
error_messages={'required': 'Please enter a valid date'},
input_formats=[
'%Y-%m-%d', # '2006-10-25'
'%m/%d/%Y', # '10/25/2006'
'%m/%d/%y'
]) # '10/25/06')
class Meta:
model = Profile
fields = ['hireDate', 'employeeNumber']
</code></pre>
<p>Here is the <strong>models.py</strong> field with the model for the profile:</p>
<pre class="lang-py prettyprint-override"><code>from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.dispatch import receiver
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
#confirmed = models.BooleanField("Confirmed", default=False)
hireDate = models.DateField(auto_now=False,
auto_now_add=False,
verbose_name='Date of Hire',
null=True)
employeeNumber = models.CharField(max_length=10,
verbose_name='Employee Number',
null=True)
@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
@receiver(post_save, sender=User)
def save_user_profile(sender, instance, **kwargs):
instance.profile.save()
</code></pre>
<p>And here is the <strong>views.py</strong> that presents the form - I'm combining two forms into one, and submitting with one button/input. The problem seems to lie with the second form (EmployeeForm), the first form (CustomUserCreationForm) seems to work fine:</p>
<pre class="lang-py prettyprint-override"><code>from django.contrib.auth import login
from django.shortcuts import redirect, render
from django.urls import reverse
from users.forms import CustomUserCreationForm, EmployeeForm
from users.models import User, Profile
from django.contrib.auth.decorators import login_required
from django.shortcuts import redirect
from django.contrib import messages #import messages
def dashboard(request):
return render(request, "users/dashboard.html")
#@login_required
# @transaction.atomic
def register(request):
if not request.user.is_authenticated:
if request.method == 'POST':
form = CustomUserCreationForm(
request.POST) #, instance=request.user)
e_form = EmployeeForm(
request.POST) #, instance=request.user.profile)
if form.is_valid() and e_form.is_valid():
user = form.save()
user.refresh_from_db(
) # load the profile instance created by the signal
e_form = EmployeeForm(request.POST, instance=user.profile)
e_form.full_clean()
e_form.save()
messages.success(request, f'Your account has been approved!')
return redirect('login')
else:
form = CustomUserCreationForm()
e_form = EmployeeForm()
print(form.errors)
print(e_form.errors)
context = {'form': form, 'e_form': e_form}
return render(request, 'users/register.html', context)
else:
return redirect('dashboard')
</code></pre>
<p>And finally here is the html for the form on the <strong>template</strong> that presents the registration page - as you can see, I've tried a few different ways to get the form to present error messages, but none of them are working for the date field:</p>
<pre class="lang-html prettyprint-override"><code> <form class="text-center" method="post">

</code></pre>
<p>I'm not sure what else I can do to get the Form to offer error message to the user if the date is entered incorrectly.</p>

popup alert - search loop
|
<p>I am a beginner so the question may be strange :)</p>
<p>I want to test the Main Menu of the website "https://tvn24.pl/"</p>
<p>I am looking for elements, I put them into the list and then iterating through it opening each page found - Works fine</p>
<p>Now step two:
On only two pages(<a href="https://kontakt24.tvn24.pl/" rel="nofollow noreferrer">https://kontakt24.tvn24.pl/</a> and <a href="https://tvn24.pl/" rel="nofollow noreferrer">https://tvn24.pl/</a> ) a window pops up in which you should click the "consent" button.</p>
<p>It is a completely different confirmation dialog for each page (different xpath, Id, etc.)</p>
<p>I would like to write functions (loops)
Which will be checked for 5 seconds if the window appeared, if so, click the accept button.
I would like this function to check both cases of "alert".
If a window "A" pops up - Click Accept - end of function
If a "B" window pops up instead of "A" - Click Accept - end of function
If no window pops up, do nothing.</p>
<p>Attention :</p>
<ol>
<li>These popups are elements that cover the entire page.</li>
<li>These are not allerts or frames - ordinary "DIV" so you can't use swith to alert or frame</li>
<li>I know, I can also use a try:</li>
</ol>
<p>Any hints?
Loop while with if, elif?</p>
<p>I tried something like this but it doesn't work</p>
<pre><code>def alert_accept_if_with_Wait_V2(driver):

Pagination did not work on the first page. The current path, &vacancy=2, didn't match any of these

<p>I am implementing search with pagination in Django.
When I clicked Next pagination button, received error:</p>

Enabling Logs for AWS WAF WebAcl does not work in CDK

<p>My goal is to enable logging for a regional WebAcl via AWS CDK. This <a href="https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-wafv2-loggingconfiguration.html" rel="nofollow noreferrer">seems to be possible</a> over Cloud Formation and there are the appropriate constructs in CDK.

resourceArn: aclArn // Arn of Acl

</code></pre>
<p>... I get an exception during <code>cdk deploy</code>, stating that the string in the LogdestinationConfig is not a correct Arn (some parts of the Arn in the log messages have been removed):</p>

How to read file zip using JSZip in Firefox SDK
|
<p>I want to make addons to work to extract the zip file locally like this (<a href="https://stuk.github.io/jszip/documentation/examples/read-local-file-api.html" rel="nofollow">here</a>).

fileInput.addEventListener('change', function(e) {
var zipFileToLoad = fileInput.files[0];
var tampJson = [];
JSZip.loadAsync(zipFileToLoad)

console.dir(zip);
zip.forEach(function (relativePath, zipEntry) {

formSheet never works on iOS

<p>I've been trying to integrate "onRequestClose" that basically closes the formSheet on iOS whenever swiped down but it never really seems to work.</p>
<p>Demo Link: <a href="https://snack.expo.dev/aN0gVemPi" rel="nofollow noreferrer">https://snack.expo.dev/aN0gVemPi</a></p>

Strange output while iterating in Python using While loop and If statement
|
<p>I am trying to iterate over the range (1,10).</p>
<p>For each number in the range, I want to apply the below logic.</p>
<ol>
<li><p>If the number is even at the start or turns even at a subsequent stage, I would like to collect the quotient of the number devided by 2 in a list.</p>
</li>
<li><p>If the number is odd at the start or turns odd at a subsequent stage, I would like to collect - triple the number plus one (3*X+1) - in the same list.</p>
</li>
<li><p>I want to repeat steps 1 & 2 on the newly collcted number, as the case may be, until the quotient is 1.</p>
</li>
<li><p>The list shall start with the original number and end with the last quotient, which is 1.</p>
</li>
</ol>
<p>I have written the below code and it is working fine for all initial values, excepting when the initial value is 3 or 6 (ie., when i is 3 or 6). The output for 3 should have been [3,10,5,16,8,4,2,1] and for 6 shall be [6,3,10,5,16,8,4,2,1]. Instead, I am getting just [3,1] and [6,3,1] respectively. Why is this? Any feedback will be appreciated.</p>
<pre><code>d ={}
for i in range(1,10):
x=i
l=[x]
while (x // 2) != 1:
if (x%2) == 0:

Not able to query dynamoDb data using GeoDataManager in Node
|
<p>I am trying to follow the very basic tutorial of Geo Library for Amazon DynamoDB given here <a href="https://www.npmjs.com/package/dynamodb-geo" rel="nofollow noreferrer">https://www.npmjs.com/package/dynamodb-geo</a>.
Even after following the steps mentioned in link, my myGeoTableManager.queryRadius() call is not giving me any result.
Below are the steps that I follow.</p>
<p>I created the dynamoDB table with below script</p>
<pre><code>require("dotenv").config();
var AWS= require('aws-sdk');
AWS.config.update({accessKeyId: process.env.accessKeyId, secretAccessKey: process.env.secretAccessKey, region: "us-east-1"});
const ddb = new AWS.DynamoDB();
const ddbGeo = require('dynamodb-geo');
const config = new ddbGeo.GeoDataManagerConfiguration(ddb, 'locationData');
config.hashKeyLength = 5;
const createTableInput = ddbGeo.GeoTableUtil.getCreateTableRequest(config);
// Tweak the schema as desired
createTableInput.ProvisionedThroughput.ReadCapacityUnits = 5;
console.log('Creating table with schema:');
console.dir(createTableInput, { depth: null });
// Create the table
ddb.createTable(createTableInput).promise()
// Wait for it to become ready
.then(function () { return ddb.waitFor('tableExists', { TableName: 'locationData' }).promise() })
.then(function () { console.log('Table created and ready!') });
</code></pre>
<p>Then I insert and query data in dynamoDB using below script.</p>
<pre><code>require("dotenv").config();
var AWS= require('aws-sdk');
AWS.config.update({accessKeyId: process.env.accessKeyId, secretAccessKey: process.env.secretAccessKey, region: "us-east-1"});
const ddb = new AWS.DynamoDB();
const ddbGeo = require('dynamodb-geo');
const config = new ddbGeo.GeoDataManagerConfiguration(ddb, 'locationData');
config.hashKeyLength = 5;
const myGeoTableManager = new ddbGeo.GeoDataManager(config);
myGeoTableManager.putPoint({
RangeKeyValue: { S: '1234' },
GeoPoint: {
latitude: 28.749472,
longitude: 77.056534
},
PutItemInput: {
Item: {
country: { S: 'country1' },
capital: { S: 'capital1' }
},
}
}).promise()
.then(function() { console.log('Insert Done!') });
myGeoTableManager.putPoint({
RangeKeyValue: { S: '5678' },
GeoPoint: {
latitude: 28.749999,
longitude: 77.056999
},
PutItemInput: {
Item: {
country: { S: 'country2' },
capital: { S: 'capital2' }
},
}
}).promise()
.then(function() { console.log('Insert Done!') });
myGeoTableManager.queryRadius({
RadiusInMeter: 100000,
CenterPoint: {
latitude: 28.749888,
longitude: 77.056888
}
}).then((locations) => {
console.log(locations);
});
</code></pre>
<p>Even with exactly same latitude and longitude, myGeoTableManager.queryRadius() is giving me empty response.</p>

JavaFX functions do not work even though there are no errors
|
<p>I'm following a tutorial loosely by thenewboston and I'm running into a bit of a roadblock. To my understanding the ID in the .JFXM file is equivalent to a variable in the controller class. The onAction command is a reference to a function in the controller class.</p>
<p>The tutorial link: <a href="https://www.youtube.com/watch?v=LMdjhuYSrqg" rel="nofollow noreferrer">https://www.youtube.com/watch?v=LMdjhuYSrqg</a></p>
<p>What I don't understand:</p>
<ol>
<li><p>Why I need to initialize the variable <code>public Button loginBtn = new Button();</code> when in the tutorial he does not. </p></li>
<li><p>Why does setText do nothing <code>loginBtn.setText("aahh!");</code></p></li>
<li><p>If I wanted to get text from a field, I would use <code>System.out.println(FXuserLoginName.getText());</code> Which results in an error if the variable is not initialized. If It IS initialized, nothing happens. </p></li>
</ol>
<p>Any help is appreciated. Below is the code:</p>
<pre><code>package application;
import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.PasswordField;

import javafx.scene.layout.BorderPane;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
public class Jfx extends Application {
public Button loginBtn = new Button();
TextField FXuserLoginName;
PasswordField userLoginPassword;
@Override
public void start(Stage primaryStage) throws Exception {
try {
Parent root = FXMLLoader.load(getClass().getResource("Login.fxml"));
Scene scene = new Scene(root,208,208);
scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
primaryStage.setTitle("Odin");
primaryStage.setScene(scene);
primaryStage.show();
} catch(Exception e) {
e.printStackTrace();
}
}
public void ActionloginButton() {//logs into database, loginButton is connected to Login.fxml there #loginButton is present
loginBtn.setText("aahh!");
System.out.println("Login button..");
//System.out.println(FXuserLoginName.getText());
System.out.println("Got text");
}

Access "too few parameters" or crash but only before compact and repair
|
<p>Bit of an odd one here, essentially I have a VBA function in Microsoft Access that takes two arguments provided and cuts the data from the existing table to a temp table, and then compares this to the latest data from an external an SQL database and then reappends the updated information.</p>
<p>This has worked fine for years, and has never been touched, until recently, everytime I run the function I get an error:</p>
<blockquote>
<p>Run-time error '-2147217904(8004e10)':
Too few parameters. Expected 2.</p>
</blockquote>
<p>However, if I manually compact and repair, or recompile the database, this error goes away and the function completes as normal. But only for that session, currently the staff that use this function have to compact and repair everytime they open the Acces front end to make the function complete. Compact and repair on close does not work.</p>
<p>The code is below, but again, it has worked as-is for year with no changes and works after a C&R.</p>

What does 'x' do in curve/dnorm, and why does it work in my function?
|
<p>I am making a function <code>Prop.Histogram()</code> that plots data as a histogram showing the proportions with a normal distribution curve added to it. Addition of the curve was difficult for me to achieve, but I succeeded (see code below)!</p>
<p>Note: I personally prefer to work with the pipe-operator <code>%>%</code> from the package magrittr in my codes. Though, as probably not everyone is familiar with this operator and/or this package (or they prefer not to use it), I'll also provide the same code without using magrittr below.</p>
<p><strong>Code using magrittr</strong></p>
<pre><code>Prop.Histogram <- function(data,
xlim_min, xlim_max, x_BreakSize,
ylim_max, y_steps) {
# Load packages
library(magrittr)
# Make histogram of data without y-axis
hist(data, freq = FALSE, ylab = "Proportion",
xlim = c(xlim_min, xlim_max), breaks = seq(from = xlim_min, to = xlim_max, by = x_BreakSize),
ylim = c(0, ylim_max %>% divide_by(., x_BreakSize)), yaxt = "n")
# I divided ylim_max by x_BreakSize, as I want ylim_max to be equal to the max proportion shown on the y_axis (and not to the max density)
# Add y-axis that shows proportion and not density
axis(side = 2,
at = seq(from = 0, to = ylim_max %>% divide_by(., x_BreakSize), by = y_steps %>% divide_by(., x_BreakSize)),
labels = seq(from = 0, to = ylim_max, by = y_steps))
box()
# Add curve to histogram
curve(dnorm(x, mean = mean(data), sd = sd(data)), lwd = 5, add = TRUE, yaxt = "n")
}
</code></pre>
<p><strong>Same code without using magrittr</strong></p>
<pre><code>Prop.Histogram <- function(data,
xlim_min, xlim_max, x_BreakSize,
ylim_max, y_steps) {
# Load packages
library(magrittr)
# Make histogram of data without y-axis

xlim = c(xlim_min, xlim_max), breaks = seq(from = xlim_min, to = xlim_max, by = x_BreakSize),
ylim = c(0, ylim_max/x_BreakSize), yaxt = "n")
# I divided ylim_max by x_BreakSize, as I want ylim_max to be equal to the max proportion shown on the y_axis (and not to the max density)
# Add y-axis that shows proportion and not density
axis(side = 2,
at = seq(from = 0, to = ylim_max/x_BreakSize, by = y_steps/x_BreakSize),
labels = seq(from = 0, to = ylim_max, by = y_steps))
box()
# Add curve to histogram
curve(dnorm(x, mean = mean(data), sd = sd(data)), lwd = 5, add = TRUE, yaxt = "n")
}
</code></pre>
<p>This code does exactly what I want it to do: it plots the proportions and adds a normal distribution curve to the plot. Though, I do have difficulties understanding why addition of the curve actually works.</p>
<p><strong>Main question (1)</strong>: I have to put <code>x</code> as the first argument in <code>dnorm()</code>, and even though I have not defined <code>x</code>, it works! So my first and main question is: what is <code>x</code>, what does it do, and why does it work in my function?</p>
<p><strong>Second question (2)</strong>: My second question is whether it is possible (and, if so, how) to use magrittr pipe-operators (<code>%>%</code>) in the line of code that adds the curve to the plot. (Even if using operators is not the best way to do so in this case, I am still interested in the answer as I am eager to learn!)</p>
<hr />
<p>First of all, for those who want to try out my code: here is some data that is representative of data that I want to plot:</p>
<pre><code>data <- rnorm(724, mean = 84, sd = 33)
Prop.Histogram(data,
xlim_min = -50, xlim_max = 200, x_BreakSize = 10,
ylim_max = 0.15, y_step = 0.05)
</code></pre>
<hr />
<p><strong>Main question (1)</strong>: role of <code>x</code> in <code>dnorm()</code>/<code>curve()</code></p>
<p>I started by using <code>data</code> instead of <code>x</code> as the first argument of <code>dnorm()</code>, but this didn't work as it resulted in the following error message:</p>
<pre><code> Error in curve(dnorm(data, mean = mean(data), sd = sd(data)), lwd = 5, :
'expr' must be a function, or a call or an expression containing 'x'
</code></pre>
<p>But then, when I take <code>dnorm(data, mean = mean(data), sd = sd(data))</code> and run it individually (not as an argument of <code>curve()</code>, it gives me 724 values (of which I don't know what they meaning, but at least it's not an error message). Which is weird, since using <code>data</code> as the first argument when <code>dnorm()</code> is part of <code>curve</code> in my formula results in an error message as we saw previously.</p>
<p>Then, when I change <code>data</code> for <code>x</code> and run <code>dnorm(x, mean = mean(data), sd = sd(data))</code> (again not as an argument of <code>curve()</code>), it gives me another error message:</p>
<pre><code> Error in dnorm(x, mean = mean(data), sd = sd(data)) :
object 'x' not found
</code></pre>
<p>This I can understand, as I've not defined <code>x</code> anywhere in my code. But that rises the question: why do I not get this same error message when I run my (working) function.</p>
<p>In short, I observed that <code>x</code> must be the first argument in <code>dnorm()</code> when <code>dnorm()</code> is used as an argument in <code>curve()</code>, but <code>x</code> cannot be used as the first argument when <code>dnorm()</code> is used individually. Conclusion: I am lost.</p>
<p>Of course, when I am lost in R, I always look at the help page of R. The help page of <code>dnorm()</code> states that <code>x</code> is a vector of quantiles... that's it. I know those words individually, but have no idea what it means in my code (as I've not defined <code>x</code>, so what vector or what quantiles is the R help page talking about?).</p>
<hr />
<p><strong>Second question (2)</strong>: use of magrittr in code</p>
<p>I've tried to write the code <code>curve(dnorm(x, mean = mean(data), sd = sd(data)), lwd = 5, add = TRUE, yaxt = "n")</code> using magrittr, but it does not work. Here are some examples I've tried:</p>
<pre><code>data %>% dnorm(x, mean = mean(.), sd = sd(.)) %>% curve(., lwd = 5, add = TRUE, yaxt = "n")
data %>% dnorm(x, mean = mean(.), sd = sd(.)) %>% curve(lwd = 5, add = TRUE, yaxt = "n")
dnorm(x, mean = mean(data), sd = sd(data)) %>% curve(., lwd = 5, add = TRUE, yaxt = "n")
</code></pre>
<p>They all result in the same error message:</p>
<pre><code> Error in dnorm(x, mean = mean(data), sd = sd(data)) :
object 'x' not found
</code></pre>
<p>I'd like to know if it's possible to use magrittr operators like <code>%>%</code> in this situation (even if it's not the best option).</p>
<hr />
<p>PS. This is my first time posting, so please feel free to give feedback or ask me for more information if needed. Thank you in advance!</p>

Query that returns values where a certain number of rows meet certain condition
|
<p>I'm trying to make a report and i'm having some dificulty designing a query to show the data i need.</p>
<p>I have 2 tables:</p>
<pre><code>+-----------+------------+----------+
+TherapyID + CostumerID + ClinicID +
+-----------+------------+----------+
+ 1 + John + Clinic 1 +
+-----------+------------+----------+
+ 2 + Susan + Clinic 2 +
+-----------+------------+----------+
+ 3 + Mary + Clinic 3 +
+-----------+------------+----------+
+-----------+--------------+-----------+--------+
+TherapyID + TherapyLine + Treatment + Result +
+-----------+--------------+-----------+--------+
+ 1 + 1 + A + Success+
+-----------+--------------+-----------+--------+
+ 1 + 2 + B + Success+
+-----------+--------------+-----------+--------+
+ 1 + 3 + C + Success+
+-----------+--------------+-----------+--------+
+ 2 + 1 + A + Success+
+-----------+--------------+-----------+--------+
+ 2 + 2 + B + Fail +
+-----------+--------------+-----------+--------+
+ 2 + 3 + C + Success+
+-----------+--------------+-----------+--------+
+ 3 + 1 + A + Success+
+-----------+--------------+-----------+--------+
+ 3 + 2 + B + Success+
+-----------+--------------+-----------+--------+
+ 3 + 3 + C + Fail +
+-----------+--------------+-----------+--------+
</code></pre>
<p>I need to make a query that shows me only the customers or therapyid's that have successfully received all treatments <strong>A,B,C</strong></p>
<p>The Query Result should be like this:</p>
<pre><code>+------------+-------------+----------+---------+-----------+---------+
+ TherapyID + TherapyLine + Customer + Clinic + Treatment + Result +
+------------+-------------+----------+---------+-----------+---------+
+ 1 + 1 + John + Clinic 1+ A + Success +
+------------+-------------+----------+---------+-----------+---------+
+ 1 + 2 + John + Clinic 1+ B + Success +
+------------+-------------+----------+---------+-----------+---------+
+ 1 + 3 + John + Clinic 1+ C + Success +
+------------+-------------+----------+---------+-----------+---------+
</code></pre>
<p>This was the only therapyid where all treatments <strong>A,B,C</strong> where <strong>Success</strong>
I really don't have any idea on how to query this, what i have tried up to now
allways returns results from <strong>TherapyID</strong> *<em>2,3</em>* where result was <strong>Success</strong> too.
Thx in advance for the help.</p>

ASP.NET Core & SPA - client files not published when the client is outside of the server folder
|
<p>I have a project which has separate client and server folders and my goal is to include client files during the server's publish process. The folder structure looks like this</p>
<pre><code>|- server
| |- src
| |- MyProject
| |- MyProject.csproj
|- client
|- src
|- dist
</code></pre>
<p>Using the default SPA template which defines <code>SpaRoot</code>, in my case <code>../../../client/src/</code> and the following item group definition</p>
<pre><code><ItemGroup>
<DistFiles Include="$(SpaRoot)dist\**; $(SpaRoot)dist-server\**" />
<DistFiles Include="$(SpaRoot)node_modules\**" Condition="'$(BuildServerSideRenderer)' == 'true'" />
<ResolvedFileToPublish Include="@(DistFiles->'%(FullPath)')" Exclude="@(ResolvedFileToPublish)">
<RelativePath>%(DistFiles.Identity)</RelativePath>
<CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
<ExcludeFromSingleFile>true</ExcludeFromSingleFile>
</ResolvedFileToPublish>
</ItemGroup>
</code></pre>
<p>From the logs I can see this results in copying the files elsewhere <code>Copying file from "C:\MyProject\client\src\dist\img\ic_mail.svg" to "C:\MyProject\server\src\MyProject\obj\Release\client\src\dist\img\ic_mail.svg".</code> while the target path should be <code>C:\MyProject\server\src\MyProject\obj\Release\netcoreapp3.1\PubTmp\Out\appsettings.Development.json</code>. I'm assuming it's caused by the different parent directory because the common parent is 3 levels up the hierarchy and the files are also copied to a directory 3 levels higher than they should be.</p>
<p>I tried prefixing the <code>SpaRoot</code> with <code>$(ProjectDir)</code>, but that did not help. My goal is to copy the files from the <code>dist</code> folder to <code>wwwroot</code> located at the root of the publish folder. I attempted to adjust the <code>ResolvedFileToPublish</code>, but I was not able to retrieve the items' relative path (relative to the <code>dist</code> folder).</p>
<p><strong>Edit:</strong> A csproj based workaround was to copy the files manually to <code>wwwroot</code> in the <code>BeforeTargets</code> hook. Can this produce any unforeseen problems? (mostly the <code><ClientDistFile/></code>)</p>
<pre><code><ItemGroup>
<ClientDistFiles Include="$(SpaRoot)dist/**/*.*"/>
</ItemGroup>
<Target Name="PublishRunWebpack" BeforeTargets="ComputeFilesToPublish">
<!-- As part of publishing, ensure the JS resources are freshly built in production mode -->
<Exec WorkingDirectory="$(SpaRoot)" Command="yarn install" />
<Exec WorkingDirectory="$(SpaRoot)" Command="yarn build:$(TargetEnvironment)" />
<Copy
SourceFiles="@(ClientDistFiles)"
DestinationFiles="@(ClientDistFiles->'wwwroot\%(RecursiveDir)%(Filename)%(Extension)')"
/>
</Target>

Incorrect row numbering sequence
|
<p>I have two tables (questions and answers) with a row number for questions and another for answers. The row number for questions increments when the question changes. The row number for answers increments each answer and resets to 1 for each new question. Both row numbering increments as intended, but the sort order is wrong. Also, I don't want the query outputs the variable that checks if the current record's question matches the last records question.</p>
<p>I believe the problem is the record sorting is performed last, when it should be the variables' assignment that happens last. I've tried to adapt the solution at <a href="https://stackoverflow.com/questions/19721651/mysql-get-row-position-with-order-by-incorrectly-numbered">MySQL get row position with ORDER BY incorrectly numbered</a> but I keep getting errors. I don't know how to 'turn off' the @currQ being displayed.</p>
<p>Table questions has (question_id,question,display_order)
Table answrs has (answer_id, question_id_fk, answer, display_order)</p>
<pre><code>SET @q_row=0,@a_row=0,@currQ='';
SELECT
@q_row:=CASE WHEN q.question=@currQ THEN @q_row ELSE @q_row+1 END AS
'Question No.',
q.question,
@a_row:=CASE WHEN q.question=@currQ THEN @a_row+1 ELSE 1 END AS
'Answer
No.',
a.answer, @currQ:=q.question
FROM
questions q
INNER JOIN
answers a ON q.question_id=a.question_id_fk
ORDER BY
q.question,a.answer ASC;
</code></pre>
<p>The dynamic numbering works, but the sequence is in the wrong order.. </p>
<pre><code>Question No. question Answer No. answer @currQ:=q.question

(Homework) Running, but not returning the values I need

Removing d3-flame-graph when loading new data
|
<p>Recently I picked up a project that has <code>d3-flame-graph</code> on it and the graph is displayed according to the Filters defined on another component.
My issue is that when searching with new parameters I can't seem to clean the previous chart and I was wondering if someone could help me. Basically what I'm having right now is, when I first enter the page, the loading component, then I have my graph and when I search for a new date I have the loading component but on top of that I still have the previous graph</p>

SQL - How to count number of distinct values (payments), after sum of rows where they have another column value (Due Date) in common
|
<p>My 'deals_payments' table is:</p>
<pre><code>Due Date Payment ID
1-Mar-19 1,000.00 123
1-Apr-19 1,000.00 123
1-May-19 1,000.00 123
1-Jun-19 1,000.00 123
1-Jul-19 1,000.00 123
1-Aug-19 1,000.00 123
1-Jun-19 500.00 456
1-Jul-19 500.00 456
1-Aug-19 500.00 456
</code></pre>
<p>I have the SQL code:</p>
<pre><code>select
count(*), payment
from (select deals_payments.*,
(row_number() over (order by due_date) -
row_number() over (partition by payment order by due_date)
) as grp
from deals_payments
where id = 123
) deals_payments
group by grp, payment
order by grp
</code></pre>
<p>which gives me what I want - the number of payments on each distinct amount - (here I only asked for ID 123):</p>
<pre><code>COUNT(*) PAYMENT
6 1000.00
</code></pre>
<p>But now I need the sum of payments of the two ID's (123 and 456), where the due dates are the same, and count the number of payments on each distinct amount, as:</p>
<pre><code>COUNT(*) PAYMENT
3 1000.00
3 1500.00
</code></pre>
<p>I tried the below but it gives me the 'missing right parenthesis' error. What is wrong??</p>
<pre><code> select
count(*),
(select
sum(total) total
from (select distinct
due_date,
(select
sum(payment)
from deals_payments
where (due_date = a.due_date)) as total
from deals_payments a
where a.id in (123, 456)
and payment > 0)
group by due_date
order by due_date) b
from (select deals_payments.*,
(row_number() over (order by due_date) -
row_number() over (partition by payment order by due_date)
) as grp
from deals_payments
where id = 123
) deals_payments
group by grp, payment
order by grp
</code></pre>

AWS problem accessing Spring cloud eureka server
|
<p>I am migrating my spring cloud eureka application to AWS ECS and currently having some trouble doing so. </p>
<p>I have an ECS cluster on AWS in which an EC2 service of eureka-server
is running on it. in this service, there is a task running</p>
<p><strong>My problem is that:</strong> </p>
<p>For my Eureka-server task, it suppose to run on External Link 18.136.147.71:8761 , but it isn't.This 18.136.147.71 is an auto assigned IP by AWS. the only setting i made was allocating an Elastic IP via EC2 Panel.</p>
<p>Although from CloudWatch log i can see that the service is running normal, i am unable to access the link as it always gives this error </p>
<pre><code>This site can’t be reached. 18.136.147.71:8761 took too long to respond.
</code></pre>
<p><strong>what are some possible errors that might have lead to this problem?
there is no problem with the docker image because i am able to run it locally on my computer.</strong> </p>
<p>below are my CloudWatch Log. This log is exactly the same as my local terminal output when i run the docker image locally:</p>

Recylerview items that are visible are not getting updated when notifyDataSetChanged() is called
|
<p>I am having a recycler view whose vies of the items that are visible are not getting updated, when notifyDataSetChanged() is called. The items that are invisible are getting updated without any problem.</p>
<p>I have seen that this has been a problem with listview as given here:
<a href="https://stackoverflow.com/questions/19635220/listview-not-refreshing-already-visible-items">List view not refreshing already visible items</a></p>

Iterate through DataContext items without casting it to a viewmodel type
|
<p>Is their a way to access Items contained in a DataContext without having to explicitly cast it to this <code>ViewModel</code>.</p>
<p>Let's say I'm binding a <code>DataContext</code> on an MvxFrameControl view, then I obtain this DataContext in code-behind once it is binded. It will look like an anonymous object containing a list of Items that are known as the children of this <code>ViewModel</code>. Can I swiss-bind these items, or some properties of this DataContext to another object, and so on?</p>
<p>I.e.</p>
<pre><code>this.DelayBind(() =>
{
var data = DataContext;
// It looks like data contains something called "Items" with a list of children viewModels.
});
</code></pre>
<p>Can I access <code>DataContext.Items[0]</code>, or at least <code>DataContext.Items</code>, and bind it to an observable collection? Then finally swiss-bind some Items to views (<code>MvxFrameControl</code>s) on their <code>DataContext</code>?</p>
<p>So, summary: I'm curious if there is a way to work in code-behind with <code>DataContext</code> and its content so I could create a generic <code>MvxFrameControl</code> that would dispatch the data to custom views based on swiss-binding.</p>
<p>I have <code>ViewModels</code> containing lists of lists, and I want to handle a lot of situations in code-behind as I've experienced a lot of memory problems with <code>MvxListView</code>s containing <code>MvxListView</code>s.</p>
<p>[Edit]</p>
<p>This is actually what I was doing in my code that led me to think I should completely redefine how bindings are done. I'll write a minimal fake axml:</p>
<p>// Warning to anyone: this is a fake layout, don't use that</p>
<p>view_myactivity_layout.axml :</p>
<pre><code><LinearLayout>
<MvxListView
android:MvxItemTemplate="@layout/food_category_item"
local:MvxBind="ItemsSource FoodCategories" />
</LinearLayout>
</code></pre>
<p>food_category_item.axml:</p>
<pre><code><LinearLayout>
<TextView
local:MvxBind="Text Category" />
<MvxListView
android:MvxItemTemplate="@layout/list_of_food_for_a_category_item"
local:MvxBind="ItemsSource FoodList" />
</LinearLayout>
</code></pre>
<p>list_of_food_for_a_category_item.axml:</p>
<pre><code><LinearLayout>
<TextView
local:MvxBind="Text NameOfThatFood" />
<MvxListView
android:MvxItemTemplate="@layout/list_of_colors_for_that_food_item"
local:MvxBind="ItemsSource FoodList" />
</LinearLayout>
</code></pre>
<p>[Etc...]</p>
<p>Nesting binded controls works well, but there are tons of GC happening when scrolling. So that's why I was thinking about making my own binding pattern using reflection for this case.</p>

C++ - BST segmentation fault upon deletion of node with 2 children
|
<h2>Segmentation faults when trying to delete a node with 2 children</h2>
<p>So i've recently started studying algorithms and have been working a bit on binary search trees, basing my C++ code on the pseudo code taken from the book <code>Introduction to Algorithms</code>. I'm however having large issues with it's delete function for it's binary search tree. The code for the delete function is:</p>
<pre><code>void bstDelete(BSTtree &bst, int key)
{
treeNode *z = findNode(bst, key);
if (z != nullptr)
{
treeNode *y = z;
treeNode *x;
if (z->left == bst.NIL)
{
x = z->right;
transplant(bst, z, z->right);
}
else if (z->right == bst.NIL)
{
x = z->left;
transplant(bst, z, z->left);
}
else
{
y = treeMin(z->right);
x = y->right;
if (y->parent == z)
{
x->parent = y;
}
else
{
transplant(bst, y, y->right);
y->right = z->right;
y->right->parent = y;
}
transplant(bst, z, y);
y->left = z->left;
y->left->parent = y;
}
}
}
</code></pre>
<p>Transplant function:</p>
<pre><code>void transplant(BSTtree &bst, treeNode *u, treeNode *v)
{
if (u->parent == bst.NIL)
{
v->right = u->right;
v->left = u->left;
v->right->parent = v;
v->left->parent = v;
bst.root = v;
}
else if (u == u->parent->left)
{
u->parent->left = v;
}
else
{
u->parent->right = v;
}
v->parent = u->parent;
}
</code></pre>
<p>I'm not expecting someone to debug my code, I've just sat pretty much for multiple days trying to figure it out, looking at other people's versions of the delete function trying to understand why mine doesn't work. There's also the issue of why the book's own delete function doesn't do it's job, or if it's just me who's at fault. I would really appreciate if someone could take a look at this. I've been looking around quite a lot and still haven't found anyone having issues with this.</p>
<p><strong>Edit</strong><br>
Added other parts related to the code</p>
<pre><code>treeNode *findNode(RBtree bst, int key)
{
treeNode *z = nullptr;
treeNode *x = bst.root;
treeNode *y = bst.NIL;
while (x != nullptr && x != bst.NIL)
{
y = x;
if (key < x->value)
{
x = x->left;
}
else
{
x = x->right;
}
if (y->value == key)
{
break;
}
}
if (y->value == key)
{
z = y;
}
return z;
}
</code></pre>
<pre><code>treeNode *treeMin(treeNode *root)
{
treeNode *treeNode = root;
while (treeNode->left != nullptr)
{
treeNode = treeNode->left;
}
return treeNode;
}
</code></pre>
<pre><code>struct treeNode
{
treeNode *left;
treeNode *right;
treeNode *parent;
std::string color;
int value;
treeNode() : left(nullptr), right(nullptr), parent(nullptr) {}
treeNode(int paramValue) : left(nullptr), right(nullptr), parent(nullptr), value(paramValue) {}
treeNode(int paramValue, treeNode *parent) : value(paramValue), parent(parent) {}
};
</code></pre>
<pre><code>struct BSTtree
{
treeNode *root;
treeNode *NIL;
BSTtree()
{
NIL = new treeNode();
root = nullptr;
}
};
</code></pre>
<p>Reason i have with NIL is so that i can easier make this into an RB tree later on. The smallest scale needed to cause a crash is a 3 node tree, where you have a root, and it has a right and left child. That way you push the delete function into case three, where it has to find a successor and transplant it. It's in this part of the delete-function which it crashes and gives me a segmentation-fault.</p>
<p><strong>Edit 2</strong><br>
Code which causes a crash:</p>
<pre><code>int main()
{
BSTtree bst;
bstInsert(bst, 5);
bstInsert(bst, 7);
bstInsert(bst, 2);
bstDelete(bst, 5);
}
</code></pre>
<p>Insert function</p>
<pre><code>void bstInsert(BSTtree &bst, int key)
{
treeNode *z = new treeNode(key);
treeNode *y = bst.NIL;
treeNode *x = bst.root;
while (x != nullptr && x != bst.NIL)
{
y = x;
if (z->value < x->value)
{
x = x->left;
}
else
{
x = x->right;
}
}
z->parent = y;
if (y == bst.NIL)
{
bst.root = z;
z->parent = bst.NIL;
}
else if (z->value < y->value)
{
y->left = z;
}
else
{
y->right = z;
}
z->left = bst.NIL;
z->right = bst.NIL;
}
</code></pre>
<p>The nullptr is not a problem here as it's resolved in the insert function, as you can see if it's root, root is given <code>bst.NIL</code> as it's parent. I agree it's error prone to have this construction, it's only there to be able to be used for red and black trees which uses a specific NIL node instead of nullptr.</p>

How to avoid putting dll.config files containing EF configuration into bin output directory?
|
<p>In my build artifacts for .NET(C#) app I have a lot of <code>dll.config</code> files. I don't know why they're put there. I looked at all my <code>packages.config</code>, <code>app.config</code>, <code>web.config</code> files and they have <code>Do Not Copy</code> setting in their property. I can't see any settings that would prevent these config files to be put in the output directories?</p>
<p>How I can prevent their existence?</p>
<p>The only thing I can find in these files is EF stuff:</p>

<p>Setting a poster reduces this to poster + approx. 3 requests.</p>
<p>Since I have many videos on a page, I don't want the browser to make <em>any</em> requests until the video is clicked.</p>
<p>What more can I do besides set a poster and disable preload?</p>

Can someone explain that why the BehaviorSubject result like this?
|
<p>I wrote a service contain a BehaviorSubject called loginStatus and a function to return that.</p>
<pre><code>private loginStatus = new BehaviorSubject<boolean>(false);
getLoginStatus(): Observable<boolean> {
return this.loginStatus;
}
</code></pre>
<p>Then I subscribe it in other component's DOM with a async pipe in 4 different div, I just commented the shareReplay to show what I'm wondering.</p>
<pre><code> loginStatus$ = this.authService.getLoginStatus().pipe(
switchMap(res => {
if (!res) { return this.authService.isLoggedIn(); }
else { return of(res); }
}),
tap(res => console.log('tap: ' + res)),
//shareReplay(1),
);
</code></pre>
<p>The isLoggedIn is a http request to check am I logged in or not, I check the loginStatus value in the switchMap, if it's false then call the isLoggedIn</p>
<pre><code>isLoggedIn(): Observable<boolean> {
console.log('called isLoggedIn');
return this.httpService.get('/auth/isLoggined').pipe(
map(res => {
console.log('isLoggedIn res: ' + JSON.stringify(res));
if (res) {
this.loginStatus.next(true);
this.firstName = res.first_name;
this.lastName = res.last_name;
this.tel = res.tel;
return 'fool';
} else {
this.clearAll();
return false;
}
}),
</code></pre>
<p>Finally It's my console result:</p>
<pre><code>called isLoggedIn
called isLoggedIn
called isLoggedIn
called isLoggedIn
</code></pre>
<p>isLoggedIn called 4 times because of my 4 async pipe, and the loginStatus is false.</p>
<p>while the first http request response, I got a json object like {first_name:xxx, last_name:yyy, 1234}, so I push the true to the loginStatus and return a 'fool' to the further operator.</p>
<p>I suppose that I will get the fool in the tap operator of the loginStatus$, but it doesn't.</p>
<pre><code>isLogedIn res: {"logined":true,"first_name":"xxx","last_name":"yyy","tel":"1234"}
tap: true
tap: true
tap: true
tap: true
</code></pre>
<p>I only got the response of the first isLoggedIn request, the other 3 is lost.
And I never get the fool, all the async pipe get the true from the loginStatus BehaviorSubject I guess.</p>
<p>Then I commented the this.loginStatus.next(true) in the isLoggedIn function to compare the result.</p>
<pre><code>isLogedIn res: {"logined":true,"first_name":"xxx","last_name":"yyy","tel":"1234"}
tap: fool
isLogedIn res: {"logined":true,"first_name":"xxx","last_name":"yyy","tel":"1234"}
tap: fool
isLogedIn res: {"logined":true,"first_name":"xxx","last_name":"yyy","tel":"1234"}
tap: fool
isLogedIn res: {"logined":true,"first_name":"xxx","last_name":"yyy","tel":"1234"}
tap: fool
</code></pre>
<p>It's result with this which is what I prefered, I called 4 times, so I got 4 responses and It pass the fool to the tap 4 times.</p>
<p>I wanna know why the other reponse is lost when I change the BehaviorSubject in the process of the first subscription.<br />
And why all 4 subscription get the true value, I suppose at least the first time will get the fool.<br />
Does it means the BehaviorSubject will cancel the further process when change rather than complete it?</p>

Unexpected results for yaml-cpp comparisons
|
<p>Consider the following code (yamltest.cpp):</p>
<pre><code>#include <yaml-cpp/yaml.h>
#include <iostream>
#include <string>
int main() {
std::string val = "[1, 2, 3]";
YAML::Node yn0 = YAML::Load(val);
YAML::Node yn1 = YAML::Load(val);
std::cout << "===== yn0 =====\n" << yn0 << std::endl;
std::cout << "\n" << std::endl;
std::cout << "===== yn1 =====\n\n" << yn1 << std::endl;
std::cout << std::boolalpha;
std::cout << "yn0 == yn0: " << (yn0==yn0) << std::endl;
std::cout << "yn1 == yn1: " << (yn1==yn1) << std::endl;
std::cout << "yn0 == yn1: " << (yn0==yn1) << std::endl;
std::cout << "yn1 == yn0: " << (yn1==yn0) << std::endl;
std::cout << "YAML::Load(val) == YAML::Load(val): " << (YAML::Load(val)==YAML::Load(val)) << "\n" << std::endl;
std::cout << "yn0 != yn0: " << (yn0!=yn0) << std::endl;
std::cout << "yn1 != yn1: " << (yn1!=yn1) << std::endl;
std::cout << "yn0 != yn1: " << (yn0!=yn1) << std::endl;
std::cout << "yn1 != yn0: " << (yn1!=yn0) << std::endl;
std::cout << "YAML::Load(val) != YAML::Load(val): " << (YAML::Load(val)!=YAML::Load(val)) << std::endl;
std::cout << std::noboolalpha;
return 0;
}
</code></pre>
<p>Along with its associated Makefile:</p>
<pre><code>yt:
g++ -g -Wall yamltest.cpp -o yt -lyaml-cpp
clean:
rm yt
</code></pre>
<p>Running it produces the following results:</p>
<pre><code>$ ./yt
===== yn0 =====
[1, 2, 3]
===== yn1 =====
[1, 2, 3]
yn0 == yn0: true
yn1 == yn1: true
yn0 == yn1: false
yn1 == yn0: false
YAML::Load(val) == YAML::Load(val): false
yn0 != yn0: false
yn1 != yn1: false
yn0 != yn1: false
yn1 != yn0: false
YAML::Load(val) != YAML::Load(val): false
</code></pre>
<p>I expected all of the <code>==</code> tests to return <code>true</code> and all of the <code>!=</code> tests to return <code>false</code>, but this is clearly not happening. So, is this the correct way to compare YAML-CPP objects to test for equivalence? If not, what is the correct way?</p>
<p>This is running on CentOS 7.x and GCC 9.2.0.</p>

Passing a Datatable From One Form to Another Form
|
<p>I have a form1 and form2. Form2 is opened from form1, it has a dgv after filling it, it's copied to a datatable on a click button, and form2 is closed or visible = false. I passed the datatable to form1 but it's giving me a null reference. Here is my code in form2:</p>
<pre><code>private void button1_Click(object sender, EventArgs e)
{
perclothesdescriptionDT = new DataTable();
foreach (DataGridViewColumn col in dataGridView3.Columns)
{
perclothesdescriptionDT.Columns.Add(col.HeaderText);
}
foreach (DataGridViewRow row in dataGridView3.Rows)
{
DataRow dRow = perclothesdescriptionDT.NewRow();
foreach (DataGridViewCell cell in row.Cells)
{
dRow[cell.ColumnIndex] = cell.Value;
}
perclothesdescriptionDT.Columns.RemoveAt(0);
perclothesdescriptionDT.Rows.Add(dRow);
}
this.Visible = false;
}
public DataTable mydt
{
get
{
return perclothesdescriptionDT;
}
}
</code></pre>

PHP Upload - how to get the relative path of an uploaded file?
|
<p>I have my videos in a folder on my desktop:</p>
<pre><code>/home/john/Desktop/Samples/Vids/small.mp4
</code></pre>
<p>How can I get this file path from upload or other ways?</p>
<p>This is my html form:</p>
<pre><code><form class="form-submission" method="post" action="upload.php" enctype= "multipart/form-data">
<input type="file" name="upload[]" id="input-file" multiple required>
<button type="submit" class="btn btn-default no-gradient">Submit</button>
</form>
</code></pre>
<p>upload.php:</p>
<pre><code><?php
print_r($_FILES);
</code></pre>
<p>Result:</p>
<pre><code>Array
(
[upload] => Array
(
[name] => Array
(
[0] => small.mp4
)
[type] => Array
(
[0] => video/mp4
)
[tmp_name] => Array
(
[0] => /tmp/php1KNwas
)
[error] => Array
(
[0] => 0
)
[size] => Array
(
[0] => 383631
)
)
)
</code></pre>
<p>But there is no info of the path - <code>/home/john/Desktop/Samples/Vids/small.mp4</code></p>
<p>Any ideas how can I get it?</p>
<p>I need to find the video file path so I can send it to my youtube channel:</p>
<pre><code>// REPLACE this value with the path to the file you are uploading.
$videoPath = "/home/john/Desktop/Samples/Vids/small.mp4";
....
$media->setFileSize(filesize($videoPath));
// Read the media file and upload it chunk by chunk.
$status = false;
$handle = fopen($videoPath, "rb");
while (!$status && !feof($handle)) {
$chunk = fread($handle, $chunkSizeBytes);
$status = $media->nextChunk($chunk);
}
</code></pre>
<p>The entire video uploading code is from <a href="https://developers.google.com/youtube/v3/code_samples/php#upload_a_video" rel="nofollow">google's</a>.</p>

Unexplained halt of execution

<p>I am working on a Java process that contains 2 threads: one for reading a file's contents and adding them in one shared blocking queue; and one for retrieving the lines from the blocking queue and sending them through the network (under a specified send rate).

<p>The problem is that, after a while, both threads hang and no tuples are sent. When I run a top command in my Linux machine, I see that the Java process, in which the two threads are running in, uses a really small amount of CPU time. Why is this happening? Is this a problem with starvation? I think that starvation can be avoided by using the <code>LinkedBlockingQueue</code>.</p>
<p>Any hints?</p>
<p>Thanks,

int valeur;
static String nomCarte;
public Carte(int valeur, String nomImage) {
valeur = this.valeur;
nomCarte = this.nomCarte;

public static String getImageId() {
return nomCarte;
}
}

Delete empty dataframes from List
|
<p>Have this following dataframe's List which I'm working with inside a for Loop. Here I have two empty dataframes, x[[2]] and x[[4]]. How can I remove then inside my for loop, let's say, if I do:</p>
<pre><code>for (i in 1:length(x)){
****x[[i]] = ***remove empty dataframes in x[[i]]***
}

CopyFileExW fails with 0 for an existing file
|
<p><strong>Context:</strong></p>
<p>I have an application that searches files in a directory using <code>QDirIterator</code>, filters and copies specific files.</p>
<p><strong>Problem:</strong></p>
<p>Using the results from <a href="https://doc.qt.io/qt-5/qdiriterator.html#next" rel="nofollow noreferrer">QDirIterator::next()</a>, I ensure the file exists (as a unnecessary safe measure) using <a href="https://doc.qt.io/qt-5/qfile.html#exists" rel="nofollow noreferrer">QFile::exists(QString)</a> which is valid.</p>
<p>However, when attempting to copy the file using <a href="https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-copyfileexw" rel="nofollow noreferrer">CopyFileExW</a>, it <a href="https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-copyfileexw#return-value" rel="nofollow noreferrer">returns 0</a> meaning the file copy failed. I have absolutely no idea why.</p>

<p><strong>Sanity Tests</strong></p>
<p>I added some sanity tests to check the file content through the conversion from <code>QString</code> -> <code>LPCWSTR</code> as <code>FileCopyExW</code> requires <code>LPCWSTR</code> and it is suggested to convert <code>QString -> LPCWSTR</code> <a href="https://www.qtcentre.org/threads/65546-Can-t-convert-QString-to-LPCWSTR?p=289096#post289096" rel="nofollow noreferrer">here</a>.</p>
<p><em>Regarding the conversion, I have tried <a href="https://stackoverflow.com/a/26366143/4628115">this</a> too but it yields the same result. It is also suggested as bad practice to user c-style casts</em></p>

Android programmatically add ImageView with ConstraintLayout
|
<p>I want to programmatically insert several ImageView into a RecyclerView using ConstraintLayout.</p>
<p>To insert images in an equidistant way using Horizontal Bias, the value for each image is calculated as:</p>
<pre><code>float biasedValue = (1f / (flightPlanWeather.weather.size () + 1f)) * (i + 1f);

.sheet: Shows only once and then never again
|
<p>Working with Beta4, it seems that the bug is still existing. The following sequence of views (a list, where a tap on a list entry opens another list) allows to present the <code>ListView</code> exactly once; the <code>onDisappear</code> is never called, so the <code>showModal</code> flag changes, but does not triggers the redisplay of <code>ListView</code> when tapped again. So, for each <code>GridCellBodyEntry</code>, the <code>.sheet</code> presentation works exactly once, and then never again.</p>
<p>I tried around with several suggestions and workarounds, but none worked (e.g., encapsulating with a NavigationViewModel). I even tried to remove the List, because there was an assumption that the <code>List</code> causes that behaviour, but even this did not change anything.</p>
<p>Are there any ideas around?</p>
<p>The setup: </p>
<ol>
<li>A <code>GridCellBody</code> with this view:</li>
</ol>
<pre><code>var body: some View {
GeometryReader { geometry in
VStack {
List {
Section(footer: self.footerView) {
ForEach(self.rawEntries) { rawEntry in
GridCellBodyEntry(entityType: rawEntry)
}
}
}

}
}
}

502 error and unhealthy health status in the target group when using AWS ELB and ACM for https

<p>I'm using AWS ELB and ACM to use HTTPS on Node.js but, I have been facing 502 error.<br>

If anyone could provide me with your insight about what I am missing/doing wrong, it would be great. Please let me know if there is any other information needed.<br>
Thank you!<br>

<p><b>[Additional edits (8/21/2022)]</b></p>
As it looked similar to what was discussed on this thread (https://stackoverflow.com/questions/60738575/target-group-443-gives-health-checks-failed-with-these-codes-502?rq=1), I just tried changing the Health check protocol for the target group of HTTPS to use HTTP; however, the results (unhealthy) were the same.<br>

Apache Ignite Near Cache - local cache metrics
|
<p>I've been experimenting with Ignite Near Caches. In doing so I'm configuring a client node with two server nodes in the cluster. I instantiated a near cache and would like to see the associated metrics on the cache hits/misses. Functionally everything works fine, but I can't figure out where the near cache metrics are.</p>
<p>I've tried to extract the cache metrics via calls</p>
<pre><code>NearCacheConfiguration<Integer, Integer> nearCfg =
new NearCacheConfiguration<>();
nearCfg.setNearEvictionPolicyFactory(new LruEvictionPolicyFactory<>(100));
nearCfg.setNearStartSize(50);
IgniteCache<Integer, Integer> cache = ignite.getOrCreateCache(
new CacheConfiguration<Integer, Integer>("myCache"), nearCfg);
// run some cache puts and gets
for (int i=0; i<10000; i++) { cache.put(i, i); }
for (int i=0; i<10000; i++) { cache.get(i); }
// then try to retrieve metrics
System.out.println(cache.localMetrics());
System.out.println(cache.metrics());
</code></pre>

<p>Looks like there are no meaningful metrics. I figured that it may be part of the NearCacheConfiguration to configure stats as is the case with CacheConfiguration but no.</p>
<p>Any idea?</p>

I get a java.util.NoSuchElementException on input from System.in
|
<p>I am writing code for a program which displays a map based a file with x & y coordinates, as well as a type value.</p>
<p>My code correctly displays the ASCII map and allows me to perform functions on the map, but when the code finally returns to the switch statement where it should take input for choosing the next option, it skips the line "option = input.nextInt();" and continues to the finally block where "input.nextLine();" gives me a Java.util.NoSuchElementException.</p>
<p>Does anyone know why this is? I know that this exception usually occurs with an enumeration when there is no such element, but I don't know why my code would skip the input.nextInt() line and then fail on input.nextLine();</p>
<p>This error occurs only when the Gorgon case is activated in the viewMap Switch case at the end. I have tried adding "input.nextLine()" calls before the "input.nextInt()" call, but it doesn't make a difference.</p>
<p>Included is the code for the Switch Statement in my MapViewer program, as well as the code for building the map and displaying it. I have also added the Gorgon class at the end.</p>
