Using JavaScript with Angular Component: Cannot read property 'id' of null
|
<p>I have successfully managed to connect my external <code>JavaScript</code> file to my <code>angular</code> component, however it doesn't work in some instances.</p>
<p>I connected my <code>src/custom.js</code> file to my <code>app.component.html</code> through <code>angular.json</code>, as illustrated below: </p>
<pre class="lang-js prettyprint-override"><code>"styles": [
"node_modules/bootstrap/dist/css/bootstrap.css",
"src/styles.css"
],
"scripts": [
"node_modules/jquery/dist/jquery.js",
"node_modules/bootstrap/dist/js/bootstrap.js",
"src/custom.js"
]
</code></pre>
<p><em>Context:</em><br/>
The demo script is a simple alert saying hello that pops every time I connect to my localhost. <br/>As far as I'm aware there's no issue with the external <code>js</code> file being referenced.</p>
<p>My issue seems to come from more complex functions.<br/>
<a href="https://www.w3schools.com/howto/howto_js_draggable.asp" rel="nofollow noreferrer">Here's the example that am trying to implement</a> from w3schools.</p>
<p>And it's set up as follows:</p>
<pre class="lang-html prettyprint-override"><code><!-- app.component.html -->
<div id="mydiv">
<div id="mydivheader">Click here to move</div>
<p>Move</p>
<p>this</p>
<p>DIV</p>
</div>
</code></pre>
<pre class="lang-js prettyprint-override"><code>// custom.js
dragElement(document.getElementById("mydiv"));
function dragElement(elmnt) {
var pos1 = 0, pos2 = 0, pos3 = 0, pos4 = 0;
if (document.getElementById(elmnt.id + "header")) {
document.getElementById(elmnt.id + "header").onmousedown = dragMouseDown;
} else {
elmnt.onmousedown = dragMouseDown;
}
function dragMouseDown(e) {
e = e || window.event;
e.preventDefault();
pos3 = e.clientX; pos4 = e.clientY;
document.onmouseup = closeDragElement;
document.onmousemove = elementDrag;
}
function elementDrag(e) {
e = e || window.event;
e.preventDefault();
pos1 = pos3 - e.clientX;
pos2 = pos4 - e.clientY;
pos3 = e.clientX;
pos4 = e.clientY;
elmnt.style.top = (elmnt.offsetTop - pos2) + "px";
elmnt.style.left = (elmnt.offsetLeft - pos1) + "px";
}
function closeDragElement() {
// stop moving when mouse button is released:
document.onmouseup = null;
document.onmousemove = null;
}
}
</code></pre>
<blockquote>
<p><strong>Error: Cannot read property 'id' of null at dragElement (custom.js:13) at custom.js:6</strong></p>
</blockquote>
<p>I have come across a similar error before.<br/>My suspicion is that it has something to do with loading the <code>DOM</code> vs running the <code>js</code>? </p>
<p>Unfortunately I'm very new to <code>Angular</code>, with no experience in setting up basic web pages.</p>
<p><strong>Does anybody have any insight?</strong></p>

Spring MVC not loading resources
|
<p>This is really frustrating I would appreciate some help with this as I have a deployment on coming weekend and suddenly the application has stopped working.
I have a Spring 4.3.3 application hosted on Apache Tomcat 7 with JDK 1.7. The application was running fine when it suddenly stopped loading all the JS, CSS and image files with an HTTP Status code of 405 (Get Method not allowed). The only noticeable change that I did was update the Java installed on my laptop. I have even uninstalled that version of java but no benefit.</p>
<p>The network tab of chrome shows the following result.</p>
<p><a href="https://i.stack.imgur.com/O1vnh.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/O1vnh.png" alt="enter image description here"></a></p>

<p>Any ideas what is causing this issue of unable to find <strong>MessageBodyReader</strong> and how can we fix it?</p>
<p>Edit:</p>
<p>Used custom MessageBodyReader. But now that returns me below error. Not sure how to fix this as I am downloading a file.</p>

Optimal way of multiprocessing a rowwise matching operation between two data frames
|
<p>I'm working on an entity resolution task with large databases (<code>df1</code> ~0.5 mil. rows, <code>df2</code> up to 18 mil. rows).</p>
<p>In <code>df1</code> I have first and last names, with first names being in regex form to allow for multiple variations of the same name - I didn't bother including it in the attached example, but the string values look something like: <code>^(^robert$|^rob$|^robb$)$</code>).</p>
<p>In <code>df2</code> I have regular first and last names.</p>
<p>My approach is to go through <code>df1</code> row by row, note the last name and first name regex, then filter <code>df2</code> first for an exact last name match, then for the first name regex match.</p>
<p>This is simulated in the below code.</p>
<pre><code>library(dplyr)
library(data.table)
set.seed(1)
df1 <- data.table(id1=sprintf("A%s",1:10000),
fnreg1=stringi::stri_rand_strings(n=10000,length=2,pattern="[a-z]"),
lname1=stringi::stri_rand_strings(n=10000,length=2,pattern="[a-z]")) %>%
dplyr::mutate(fnreg1 = paste0("^(",fnreg1,")$"))
df2 <- data.table(id2=sprintf("B%s",1:100000),
fname2=stringi::stri_rand_strings(n=100000,length=2,pattern="[a-z]"),
lname2=stringi::stri_rand_strings(n=100000,length=2,pattern="[a-z]"))
process_row <- function(i){
rw <- df1[i,]
fnreg <- rw$fnreg1
ln <- rw$lname1
ln.match <- df2[lname2==ln, ]
out.match <- ln.match[grepl(fnreg, fname2), ]
return(cbind(rw,out.match))
}
## 16 seconds
tictoc::tic()
out <- lapply(1:nrow(df1), process_row) %>% do.call(rbind,.) %>% na.omit()
tictoc::toc()
</code></pre>
<p>The <code>lapply</code> format I want to keep for parallelizing. I use the following code, note I'm on Windows so I need to prepare the clusters to get it working:</p>
<pre><code>library(parallel)
prep_cluster <- function(export_vars){
cl <- makeCluster(detectCores()-1)
clusterEvalQ(cl, library(dplyr))
clusterEvalQ(cl, library(data.table))
clusterExport(cl, export_vars)
return(cl)
}
cl <- prep_cluster(list("df1","df2","process_row"))
## 2 seconds
tictoc::tic()
out.p <- parLapply(cl, 1:nrow(df1), process_row) %>% do.call(rbind,.) %>% na.omit()
tictoc::toc()
stopCluster(cl)
</code></pre>
<p>For my large datasets, my code works pretty slowly. I'm almost certain that the way I defined <code>process_row</code> is very poorly optimized. But I'm not sure how to change the function to be faster and still conform to the <code>parLapply</code> format.</p>
<p>Any tips appreciated.</p>
<p>EDIT: I'm pretty short on memory, working with only 32GB - so I need to optimize it that way too.</p>
<p>For the largest data files (18 mil rows) I am splitting them into chunks and matching each chunk separately.</p>

How to feed a list of files into a bash script
|
<p>I'm having problems feeding a large list of filenames into a command in (git for windows git, I think it's cygwin)bash shell.</p>
<p>This is the basic command that works fine with a small set of arguments: <code>git filter-branch -f --tree-filter 'rm -rf file1 directory2 file3 file4'</code> However, I have about 1500 filenames.</p>
<p>I've tried: <code>git filter-branch -f --tree-filter 'rm -rf file1 directory2... all 1500 names here'</code> but I get an error: </p>
<blockquote>
<p>/mingw64/bin/git: Argument list too long</p>
</blockquote>
<p>I've tried to use a for loop: <code>git filter-branch -f --tree-filter 'for f in $(cat files.txt) ; do rm -fr "$f" ; done'</code> and this runs through the loop with an error: </p>
<blockquote>
<p>cat: files.txt: No such file or directory</p>
</blockquote>
<p>FYI - the files.txt contents look like this:</p>
<pre><code>./file1
./directory2
./file3
./file4
</code></pre>
<p>Then I tried: <code>git filter-branch -f --tree-filter < cat files.txt</code> and <code>cat files.txt | git filter-branch -f --tree-filter</code> but I get errors about the syntax not being correct - it shows the 'help' dialogue. eg:</p>
<blockquote>
<p>usage: git filter-branch [--setup ] [--subdirectory-filter
] [--env-filter ]
[--tree-filter ] [--index-filter ]
[--parent-filter ] [--msg-filter ]
[--commit-filter ] [--tag-name-filter ]
[--original ]
[-d ] [-f | --force] [--state-branch ]
[--] [...]</p>
</blockquote>
<p>Then I thought maybe I could just add the arguments into the file like this: <code>git filter-branch -f</code></p>
<p>File: </p>
<pre><code>--tree-filter './file1 ./directory2 ./file3 ./file4'
</code></pre>
<p>But I get the 'help' dialogue again.</p>
<p>I'm sure there is a way to do this, but my unix-fu is too weak. Please help! </p>
<hr>
<p>In response to @dash-o:</p>
<p>I tried this, but am getting an error: </p>
<blockquote>
<p>C:/Program Files/Git/mingw64/libexec/git-core\git-filter-branch: eval:
line 414: unexpected EOF while looking for matching `'' C:/Program
Files/Git/mingw64/libexec/git-core\git-filter-branch: eval: line 415:
syntax error: unexpected end of file</p>
</blockquote>
<p>The files.txt lists the files one per line. However, the rm -rf requires them to be on a single line and space-delimited. </p>
<p>I tried to put the files names on a single line, but I get a different error: </p>
<blockquote>
<p>C:/Program Files/Git/mingw64/libexec/git-core\git-filter-branch: line
414: rm -rf .vs ./file1 ./directory2: command not found tree filter
failed: 'rm -rf ./file1 ./directory2'</p>
</blockquote>
<p>Maybe the single quotes are being escaped and are not wrapped around the rm command?</p>

<p>The error is related to the script which is called in TESTS.php :</p>

<p>It seems the file is not imported or there is some errors in php file which I am not able to find it out. Can anyone help me with this please as I have spent my whole day on it. Thanks.</p>

Vscode rust-analyser plugin, on macOS; failing to load workspace due to permission denied
|
<p><strong>Goal</strong></p>
<p>I'm trying to setup Visual Studio Code(vscode) on macOS for rust development.
I had my setup working, using the official rust extension, but it wasn't always consistent.
I saw that the rust-analyzer extension could provide a better experience.</p>
<p><strong>Problem</strong></p>
<p>Now that I have installed the extension, It keep throwing the following error:</p>
<pre><code>rust-analyzer failed to load workspace: "/Users/michaelbailey/.cargo" "--version" failed: Permission denied (os error 13)
</code></pre>
<p>From my understanding, the plugin is trying to execute the .cargo folder rather than cargo itself.</p>
<p>running</p>
<pre><code>$ /Users/michaelbailey/.cargo --version
zsh: permission denied: /Users/michaelbailey/.cargo
</code></pre>
<p>instead of</p>
<pre><code>$ /Users/michaelbailey/.cargo/bin/cargo --version
cargo 1.61.0 (a028ae42f 2022-04-29)
</code></pre>
<p>This is causing rust analyser to fail loading any project.</p>
<p><strong>What i have tried</strong></p>
<ul>
<li>Reinstalling the Rust-analyzer extension.</li>
<li>Disabling other rust based plugins.</li>
<li>Switching to the pre-release version.</li>
<li>reinstalling rust from the rust website.</li>
<li>clearing all rust settings.</li>
<li>creating a new project to test if my project was misconfigured somehow.</li>
</ul>
<p><strong>what i need help with</strong></p>
<ul>
<li>finding out a way to config rust-analyzer to point to the right file.</li>
<li>another way to resolve rust-analyzer.</li>
</ul>
<p>Any help or pointers on the matter would be greatly appreciated.</p>
<p><strong>Logs</strong></p>
<p>output of rust-analyzer, in the vscode output tab.</p>

Reading XML nodes in a C# program without the use of int.TryParse(node.InnerText)
|
<p>The following is a snippet of a much larger C# code. For the sake of convenience, I'm only providing the relevant information.</p>
<p>I'm trying to do a program that reads XML variables and puts them in a list. You then choose a name from the list based off of the names listed in the XML, and the values for that specific name are then shown in a series of text boxes in a Form. DValue is special, because it is a value that doesn't have to exist, so because of this, several elements in the XML form have empty nodes for DValue. An empty node should not affect the DValue previously presented.</p>
<p>For example If I chose "Additional 1" the values would be listed as 123, 4, 5, 6, but if we were to change it to "Pt 3" the values would be 123, 7, 8, 9. The DValue cannot change for empty nodes.</p>
<p>So this is where the problem comes in.</p>
<p>I was using int.TryParse(node.InnerText) to read my XML values, convert them into integers and display them in the form's boxes, but I recently found out that int.TryParse(node.InnerText) reads every node with said name, which makes things very messy. <strong>Basically, all of my empty nodes are being turned into 0 due to int.TryParse having 0 as a default value when it fails, and because of that, the program will not recognize when there's an empty node</strong>. As a result, every time I reference something with an empty node, <strong>it treats the DValue as 0 instead of doing nothing</strong>. I tried making a portion of code to read each individual DValue, and then perform the following if statement:</p>
<pre><code>if (element.IsEmpty)
{
DFound = false;
}
else
{
DFound = true;
int.TryParse(element.InnerText, out tempTRES.DVal);
}
</code></pre>
<p>But it still treats the empty variables as 0, and as a result every value is treated as "true" for the variable DFound. I've been working through a bunch of different potential solutions, but none of them seem to have worked because the empty variables would either be turned to zero, or the entire series of nodes just wouldn't load at all, but I'll leave that aside since this is already a pretty long question, and honestly, I'd have a tough time explaining some of the things I had done, but here are a few notable statements at least:</p>
<ul>
<li>string DValueText = Convert.ToString(element): I tried to convert a string value of each node into an integer so I'd never have to use InnerText, but trying to read nodes just breaks the code for reason's I'm not completely aware of yet.</li>
<li>element.InnerXml does nothing, and element.Value fails.</li>
<li>I tried setting the InnerText to something else, that way I could at least turn the empty variable into something that I could single out in an if statement, but the method I tried element.InnerText = "-100", didn't actually do anything.</li>
</ul>
<p>In summation. <strong>How can I make a clear distinction for when an XML node is "0", versus it being empty?</strong> Also, I'm sorry if this seems like a very simple problem. I've looked into this, but solutions for adding node values seem to always revolve around the assumption that one would be using int.TryParse(node.InnerText). Lastly, if something about this doesn't make sense, please let me know. As said, this is just a part of a much larger code, so it's very possible that some contextual information is missing.
The code and the XML can be found below:</p>
<hr />
<pre><code>int.TryParse(TRES.SelectSingleNode("AValue").InnerText, out tempTRES.AVal);
int.TryParse(TRES.SelectSingleNode("BValue").InnerText, out tempTRES.BVal);
int.TryParse(TRES.SelectSingleNode("CValue").InnerText, out tempTRES.CVal);
//Note: Every TRES needs an DValue node, even if empty.
if (TRES.SelectSingleNode("DOS/TRES/DValue") == null)
{
XmlElement element = TRES.SelectSingleNode("DValue") as XmlElement;
if (element.IsEmpty)
{
DFound = false;
}
else
{
DFound = true;
int.TryParse(element.InnerText, out tempTRES.DVal);
}
}
viewTRES_.Add(tempTRES);
viewTRES_.Add(tempTRES);
cbDVizViewTRES.Items.Add(tempTRES.name);
}

I am trying to store the Authorization Token fetched from the Rest API and then use it in the headers of other API calls in Flutter
|
<p>As the title of the problem explains most of it but will still elaborate more.
So I am calling an API using the POST method and registering a user which gives me response data containing only the Authorization token which needs to be used while calling other APIs.</p>
<p>Now I want to store the token and use it in the headers while making other API calls.
I am herewith attaching a few code snippets that might demonstrate what I have done actually and what needs to be done in order to get the particular outcome.
I am getting the API response for fetching the key but I am unable to understand why it is not getting stored and why cannot I use it in the headers.</p>
<p><strong>API call that returns just the token in the response</strong></p>
<pre><code> final storage = SecureStorage();
Future<UserRegistration> registration(dynamic param) async {
var client = http.Client();
try {
var response = await client
.post(Uri.https("baseURL", "endpoint"),
body: param)
.timeout(Duration(seconds: TIME_CONST))
.catchError(handleError);
if (response.statusCode == 201) {
print('Response Body: ${response.body}');
final data = jsonDecode(response.body);
///////Using the flutter secure storage here to save the token
var token = storage.writeSecureToken('key', data['key']);
print("Token Here $token");
return UserRegistration(
key: data['key'],
status: true,
);
} else {
print("Something went wrong");
return param;
}
} on SocketException {
throw FetchDataException('message', 'url');
} on TimeoutException {
throw ApiNotRespondingException("message", "url");
}
}
</code></pre>
<p><strong>API response that I am getting</strong></p>
<pre><code>Response Body: {"key":"8fb303212871a80899f0b883f3554b189fddf24b"}
</code></pre>
<p><strong>API call that I am making which requires the Authorization Header as the key received in the previous response.</strong></p>
<pre><code>Future<PhoneOTPValidate> phoneOTPvalidate(dynamic param) async {
var client = http.Client();
var token = storage.readSecureToken('key');
try {
var response = await client
.post(
Uri.https("baseURL", "endpoint"),
headers: <String, String>{
'Authorization': 'Token $token',
},
body: param)
.timeout(Duration(seconds: TIME_CONST))
.catchError(handleError);
if (response.statusCode == 200) {
print('Response Body: ${response.body}');
final data = jsonDecode(response.body);
return PhoneOTPValidate(
status: data['success'],
validate: true,
);
} else {
print("The OTP is not valid");
return param;
}
} on SocketException {
throw FetchDataException('message', 'url');
} on TimeoutException {
throw ApiNotRespondingException("message", "url");
}
}
</code></pre>
<p><strong>My Classes for the above API calls are here:</strong></p>
<pre><code>class PhoneOTPValidate {
PhoneOTPValidate({this.status, this.validate});
final String? status;
final bool? validate;
}

final String? key;
final bool? status;
}
</code></pre>
<p><strong>Flutter Secure Storage Class</strong></p>
<pre><code>class SecureStorage {
final storage = FlutterSecureStorage();
Future writeSecureToken(String key, String value) async {
var writeData = await storage.write(key: key, value: value);
print('Token Here');
return writeData;
}
Future readSecureToken(String key) async {
var readData = await storage.read(key: key);
return readData;
}
Future deleteSecureToken(String key) async {
var deleteData = await storage.delete(key: key);
return deleteData;
}
}
</code></pre>
<p><strong>Here's the output for what I have written:</strong></p>
<pre><code>Response Body: {"key":"de18d1239ed0b6be13f4c9a9d96eebeb1c401922"}
I/flutter (23010): Token Here Instance of 'Future<dynamic>'
I/flutter (23010): Token Here
</code></pre>
<p>How do I solve this problem of saving the key and using it in the headers of the other API calls?
Have almost tried all the solutions from StackOverflow but nothing gave a solid answer to how it is being done.
Am stuck at this problem for quite a few days
Would appreciate it if anyone can solve my problem considering my code.</p>

Debugging foreach in R using dorng
|
<p>I am parallelizing a task in R using <code>foreach</code> loop with reproducible results using the <code>dorng</code> operator. It is a complex code, and I have an error that I have not been able to identify even though I have run the same code with a regular <code>for</code> loop.</p>
<p>My fundamental question is: how do I debug a function within of a <code>foreach</code> loop assuming that I have reproducible results? Below is my current tentative.</p>
<p>In the <a href="https://cran.r-project.org/web/packages/doRNG/vignettes/doRNG.pdf" rel="nofollow noreferrer">vignette</a> of the doRNG package, it says that a sequence of random seeds will be generated and set at the beginning of each iteration using the R number generator "L’Ecuyer-CMRG". The sequence of random seeds can be defined using <code>set.seed</code> before the <code>foreach</code> loop:</p>
<pre><code>library(doRNG)
library(doParallel)
library(foreach)
registerDoParallel(2)
set.seed(1234)
f01 <- foreach(i = 1:100, .combine = 'c') %dorng% {
out <- 1 + i
}
r01 <- attr(f01, "rng")
set.seed(1234)
f02 <- foreach(i = 1:100, .combine = 'c') %dorng% {
out <- 1 + i
}
r02 <- attr(f02, "rng")
</code></pre>
<p>The objects <code>r01</code> and <code>r02</code> contain the sequence of seeds used in <code>f01</code> and <code>f02</code>,</p>
<pre><code>identical(f01, f02)
identical(r01, r02)
</code></pre>
<p>such that the results from the <code>foreach</code> loop and their seeds are identical as expected!</p>
<p>Then, let's consider the case when the <code>foreach</code> loop will give me a random error:</p>
<pre><code>set.seed(1234)
f03 <- foreach(i = 1:100, .combine = 'c') %dorng% {
u <- floor(runif(1, 1, 101))
if (i == as.integer(u)){
out <- "a" + "b"
} else {
out <- 1 + i
}
}
Error in { : task 67 failed - "non-numeric argument to binary operator"
</code></pre>
<p>The error occurs at iteration 67 and it is very easy to understand the error. Unfortunately, it is not the same in my case.</p>
<p>I would like to be able to use <code>debug</code> and walk through my function to understand the error. From the best of my knowlegde, I cannot use <code>debug</code> inside a <code>foreach</code> loop in R.</p>
<p>Then, I thought about capturing the error in a regular <code>for</code> loop, but running my code is very slow and, apparently, I cannot observe the error with a low number of iterations. I need to understand the error using <code>foreach</code>.</p>
<p>Although I can't recover the sequence of seeds from <code>f03</code>, I know that they will be identical to <code>r01</code> or <code>r02</code>. For iteration 67, I have</p>
<pre><code>r01[[67]]
[1] 10407 1484283582 -741709185 513087691 132931819
[6] 1318506528 -1383054295
</code></pre>
<p>Therefore, I guess that fixing my seed at <code>r01[[67]]</code> should give me the same error:</p>
<pre><code>i <- 67
set.seed(r01[[67]], kind = "L'Ecuyer-CMRG")
u <- floor(runif(1, 1, 101))
if (i == as.integer(u)){
out <- "a" + "b"
} else {
out <- 1 + i
}
u
[1] 74
</code></pre>
<p>which is not true.</p>
<p>In the doRNG <a href="https://cran.r-project.org/web/packages/doRNG/vignettes/doRNG.pdf" rel="nofollow noreferrer">vignette</a>, page 6, they have an example of using a seed in a loop from a previous loop:</p>
<pre><code>set.seed(1234)
ex01 <- foreach(i=1:5) %dorng% { runif(3) }
ex02 <- foreach(i=1:5, .options.RNG=attr(ex01, 'rng')[[2]]) %dorng% { runif(3) }
identical(ex02[1:4], ex01[2:5])
</code></pre>
<p>What am I missing?</p>

Optimizing MySQL CREATE TABLE Query
|
<p>I have two tables I am trying to join in a third query and it seems to be taking far too long.</p>
<p>Here is the syntax I am using</p>
<pre><code>CREATE TABLE active_users
(PRIMARY KEY ix_all (platform_id, login_year, login_month, person_id))
SELECT platform_id
, YEAR(my_timestamp) AS login_year
, MONTH(my_timestamp) AS login_month
, person_id
, COUNT(*) AS logins
FROM
my_login_table
GROUP BY 1,2,3,4;
CREATE TABLE active_alerts
(PRIMARY KEY ix_all (platform_id, alert_year, alert_month, person_id))
SELECT platform_id
, YEAR(alert_datetime) AS alert_year
, MONTH(alert_datetime) AS alert_month
, person_id
, COUNT(*) AS alerts
FROM
my_alert_table
GROUP BY 1,2,3,4;
CREATE TABLE all_data
(PRIMARY KEY ix_all (platform_id, theYear, theMonth, person_id))
SELECT a.platform_id
, a.login_year AS theyear
, a.login_month AS themonth
, a.person_id
, IFNULL(a.logins,0) AS logins
, IFNULL(b.alerts,0) AS job_alerts
FROM
active_users a
LEFT OUTER JOIN
active_alerts b
ON a.platform_id = b.platform_id
AND a.login_year = b.alert_year
AND a.login_month = b.alert_month
AND a.person_id = b.person_id;
</code></pre>
<p>The first table (logins) returns about half a million rows and takes less than 1 minute, the second table (alerts) returns about 200k rows and takes less than 1 minute. </p>
<p>If I run just the SELECT part of the third statement it runs in a few seconds, however as soon as I run it with the CREATE TABLE syntax it takes more than 30 minutes.</p>
<p>I have tried different types of indexes than a primary key, such as UNIQUE or INDEX as well as no key at all, but that doesn't seem to make much difference.</p>
<p>Is there something I can do to speed up the creation / insertion of this table?</p>
<p>EDIT:
Here is the output of the show create table statements</p>
<pre><code>CREATE TABLE `active_users` (
`platform_id` int(11) NOT NULL,

How to create a generic function to load a view controller?
|
<p><strong>I have been trying to write a function that works with 3 parameters in order to load a view controller but I haven't been able to make it work.</strong> </p>
<p><em>I'm new into coding</em> and I am reading a tutorial that uses 2 view controllers (login & chat). In order to go from one to the other, the guide tells me to use this whether I want to log in or log out: </p>
<pre><code>@IBAction func loginDidTapped(_ sender: Any) {
// A
let storyboard = UIStoryboard (name: "Main", bundle: nil)
// B
let logVC = storyboard.instantiateViewController(withIdentifier: "LoginVC") as! LoginViewController
// C
let appDelegate = UIApplication.shared.delegate as! AppDelegate
// D
appDelegate.window?.rootViewController = logVC
}
</code></pre>
<p>If I want to log in or log out I have to change 3 things: </p>
<ol>
<li><strong>logVC</strong> , <em>which I'd call <strong>var1</em></strong>, used in // B , // D</li>
<li><strong>"LoginVC"</strong> , <em>which I'd call <strong>var2</em></strong>, used in // B</li>
<li><strong>LoginViewController</strong> , <em>which I'd call <strong>var3</em></strong>, used in // B</li>
</ol>
<p>In my newb mind, I imagined that I could create a function that contained the <strong>"A, B, C, D"</strong> lines and let me call it anywhere later just by changing <strong>"var1, var2, var3"</strong> parameters</p>
<hr>
<p>This is what I first created using just <strong>var1</strong> and <strong>var2</strong>: </p>
<pre><code>import Foundation
import UIKit
import FirebaseAuth
class Helper {
static let helper = Helper()
func loadView (var1 : String , var2 : String) {
let storyboard = UIStoryboard (name: "Main", bundle: nil)
let var1 = storyboard.instantiateViewController(withIdentifier: var2) as! LoginViewController
let appDelegate = UIApplication.shared.delegate as! AppDelegate
appDelegate.window?.rootViewController = var1
}
}
</code></pre>
<p>I called it this way and it worked:</p>
<pre><code>Helper.helper.loadView(var1: "logVC" , var2: "LoginVC")
</code></pre>
<hr>
<p>Now, when I tried to use <strong>var3</strong> in line //B, inside the same function, Xcode underlines var3 and displays this error:</p>
<p><strong>Use of undeclared type 'var3'</strong></p>
<p>This is how it looked after adding a the <strong>var3</strong> parameter:</p>
<pre><code> func loadView (var1 : String , var2 : String , var3 : String) {
let storyboard = UIStoryboard (name: "Main", bundle: nil)
let var1 = storyboard.instantiateViewController(withIdentifier: var2) as! var3
let appDelegate = UIApplication.shared.delegate as! AppDelegate
appDelegate.window?.rootViewController = var1
}
</code></pre>
<p>This is how I would have called it if it had worked:</p>
<pre><code>Helper.helper.loadView(var1: "logVC" , var2: "LoginVC" , var3: "LoginViewController")
</code></pre>
<hr>
<p>I'd like to know if is it possible to do what I am imaging since I see functions as equations in which I can replace variables with the information I need.</p>
<p>Thank you all in advance.</p>

Icons are scoped in a veird way (CSS scoping Vue.js 3)

<p>I am not 100% sure it is the scoping issue here, but here is the thing.</p>
<p>HTML:</p>

</div>
<button :class="[sortBy === 'price' ? sortDirection : '']" @click="sort('price')">Price</button>
<button :class="[sortBy === 'size' ? sortDirection : '']" @click="sort('size')">Size</button>
</div>
</code></pre>
<p>CSS:</p>

}
}

</code></pre>
<p>In the inspector the position of both icons (unicons) are static. Is there a way to fix that? In CSS I tried to make it a bit different, but it seems like those icons are not responding to any CSS entry in this case.

Run git post-receive hook as user1, and checkout as user2
|
<p>I'm setting up a deploy-on-git-push process on a remote Debian server. It is basically the common approach of having a bare repository with a post-receive hook which does a checkout to the web server's docroot, more or less.</p>
<p>I've used slightly simpler variations of this set up successfully for years, but this time around I'm complicating it by trying to separate ownership of the git repo and the site files between 2 different users. I don't want the user who can SSH in (the git push happens over SSH) to have write perms to the site, and vice-versa (the site user shouldn't have write perms to the git repository).</p>
<ul>
<li><p>I have 1 user, let's call her <code>git-user</code>, who owns a bare git repository at <code>/var/gitrepos/my_site.git</code>, and this user is the only user allowed to connect over SSH;</p>
</li>
<li><p>I have a 2nd user, say <code>site-user</code>, who should own the checked-out files at <code>/var/www/site</code>;</p>
</li>
</ul>
<p>I push over SSH to the repo, and this means any post-receive hook runs as the user I SSH in as - <code>git-user</code> in this case. So the post-receive hook can't do the checkout itself, as the site files would end up being owned by <code>git-user</code>, not <code>site-user</code>.</p>
<p>So my post-receive simply touches a trigger file, <code>/var/run/deploy</code>. A separate script is run from <code>site-user</code>'s cron frequently, eg every minute, looking for that file. If it sees it, it does a checkout to <code>/var/www/site</code>. The relevant part of that script looks something like:</p>
<pre><code># Running as site-user
mkdir $NEW \
&& cd $NEW \
&& git --work-tree=. --git-dir=/var/gitrepos/my_site.git checkout -f www
</code></pre>
<p>However this fails with:</p>
<blockquote>
<p>fatal: Unable to create '/var/gitrepos/my_site.git/index.lock': Permission denied</p>
</blockquote>
<p>This is true, <code>site-user</code> - intentionally - does not have write permission to <code>/var/gitrepos/my_site.git</code>. I am not sure why doing a checkout to a different directory <em>needs</em> to create a lockfile in the repo, but apparently it does, and I guess I shouldn't fight that.</p>
<p>So what are the options?</p>
<ul>
<li><p><code>git clone</code> doesn't need write perms to the repo, so this works, but it means I get the whole <code>.git/</code> directory. I have to remove that, or configure the web server to disallow access, both extra steps I'd rather avoid. Not a big deal obviously but this still feels wrong;</p>
</li>
<li><p>I could add both users to a group and set up <code>g+w</code> etc, but this voids the whole point of this approach (to deny each user write perms to the other's files);</p>
</li>
<li><p>I guess I could mess with <code>sudoers</code>, and allow one user to run a command as the other user, but again this feels like I am just chipping away at the separation I'm trying to enforce?</p>
</li>
<li><p>I can do a <code>git clone</code> to <code>$TMP_DIR</code>, followed by a <code>git checkout --git-dir=$TMP_DIR/.git/</code>, but this seems super clunky, as well as taking 2x as long;</p>
</li>
</ul>
<p>Any other neat options I am missing?</p>
<h3>UPDATE</h3>
<p>As suggested by @Matt below I tried setting <code>GIT_INDEX_FILE</code> to a writeable (by <code>site-user</code>) file outside the repository. This does seem to get past the first problem, but still fails with:</p>
<blockquote>
<p>error: Unable to create '/var/gitrepos/my_site.git/HEAD.lock': Permission denied</p>
</blockquote>
<p>I don't understand why a checkout to a new location needs to modify anything in the repository?</p>

how to count lines in a csv file in java where the file doesn't have ".csv" extension?
|
<p>I want to get file lines count where file is similar to "csv" but it doesn't have ".csv" file extension. I have only filename.</p>
<p>The code i have mentioned here is the function that count file lines of only those files which have name as abc.txt or abc.csv,, but it will not read the file if the extension doesn't have .txt or .csv. That is the code won't the file if file name is only "abc" instead of "abc.csv"</p>
<p>Here's the complete program:
There are three class</p>
<pre><code>package file_count_checker;

Js animate a ball wrong, slow then faster everytime
|
<p>When I run this code first time the animation speed is slow, then every time faster.The code moves a ball, and after you touch the screen, the ball goes to where you touched. </p>
<p>But the first time, it is very slow, then every time it goes faster. Why？</p>
<p>I was expecting a similar speed, not perfectly constant, but not like that.
Also on the tenth attempt the ball goes too fast.</p>
<p>I try on my smartphone, I don't know if it will work on a computer.</p>

Django markers using geoposition

Difference in .htaccess behaviour
|
<p>I have finished developing a micro app with Phalcon and tried to move it to production server, but have encountered some problems with <code>.htaccess</code> rules.</p>
<p>Directory layout on the serwer is like this : </p>
<pre><code>/var/www
|- .htaccess
|- redmine/
|- wordpress/
|- (other dirs)
|- MyApp/
|- .htaccess
|- public/
|- .htaccess
|- api.php
</code></pre>
<p>/var/www/.htaccess : </p>
<pre><code># BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_URI} !(redmine|MyApp) [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
</code></pre>
<p>/var/www/MyApp/.htaccess :</p>
<pre><code><IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI} !(\.gif|\.jpg|\.png|\.mp3|\.ods|\.csv|\.xls)$ [NC]
RewriteRule ^$ public/ [L]
RewriteCond %{REQUEST_URI} !(\.gif|\.jpg|\.png|\.mp3|\.ods|\.csv|\.xls)$ [NC]
RewriteRule (.*) public/$1 [L]
</IfModule>
</code></pre>
<p>/var/www/MyApp/public/.htaccess :</p>
<pre><code><IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ api.php?_url=/$1 [QSA,L]
</IfModule>
</code></pre>
<p>I'm really new to all this. The top-most <code>.htaccess</code> was not setup by me, and frankly I don't know what is going on in there. The others are based on Phalcon tutorials.</p>
<p>Everything worked on my local machine, but stopped when I uploaded it. I turned on logging in both places.</p>

<p>The differences begin with the first line with <code>[perdir (...)]</code> ending with <code>/public/</code>. I don't understand why it adds <code>.php</code> and why the <code>!-f</code> rule doesn't match on the remote server.</p>
<p>Local server :<br>
OSX 10.9.3, MAMP 3.0.4, Apache 2.2.26</p>
<p>Remote server :<br>
Debian GNU/Linux 6.0.9, Apache 2.2.16</p>
<p>I wonder whether this is caused by the additional <code>.htaccess</code> file on the remote, or by the difference in Apache version.</p>
<p>I'd appreciate some explanation as to what's going on and any directions on where to look for answers.</p>
<p>Cheers!</p>

<p>I must admin that my knowledge of JSON is very terse, maybe it is just a simple fault of mine. But can anyone help me how I can generate Java objects from such a JSON Schema?</p>

Using Ghost4j with MaxProcessCount on a tomcat causes jna error
|
<p>I'm trying to develop a web-service (based on jersey) which is converting a pdf document into jpeg images.
I choosed GhostScript because I have good experiences with it and it's results (especially with embedet fonts). So I searched a way to use GhostScript with Java and found Ghost4j.</p>
<p>So I put all the Ghost4j jars into my applications lib folder (also the jna.jar). In my first tests I encountered a problem with executing the task more than once, because jna throws an error when it's launched more than one time.
So I put the jna.jar into the tomcat lib folder. That worked a littlebit better, but it only executed one task at a time. If I started another one at the same time, nothing happened. I just didn't seem to execute the other task.</p>
<p>So I tried <code>setMaxProcessCount(2);</code> to allow my application to execute more than one task at a time. Here is my code:</p>
<pre><code>private static void generateImages(String inputFile, String outputPath) throws IOException, RendererException, org.ghost4j.document.DocumentException {
PDFDocument document = new PDFDocument();
document.load(new File(inputFile));
SimpleRenderer renderer = new SimpleRenderer();
renderer.setMaxProcessCount(2);
renderer.setResolution(150);
renderer.setAntialiasing(4);
System.setProperty("jna.library.path", "C:\\Program Files\\gs\\gs9.09\\bin\\");
List<Image> images = renderer.render(document);
for (int i = 0; i < images.size(); i++) {
ImageIO.write((RenderedImage) images.get(i), "jpeg", new File(outputPath + File.separatorChar + (i + 1) + ".jpeg"));
}
}
</code></pre>
<p>But if I'm trying to execute my task, Ghost4j throws this error:</p>
<pre><code>org.ghost4j.renderer.RendererException: java.lang.Exception: java.lang.NoClassDefFoundError: com/sun/jna/Structure

<p>I guess that it has something todo with the additional JVM that Ghost4j is launching and it doesn't seem to use the same classpath that tomcat uses, but I'm not really a java expert and have no idea how to solve this problem.</p>

My custom JMeter listener cannot work in Linux
|
<p>I want to save the information about sampleResult into MySQL. So I write my own listener named Performance Logger. And it can work well on my Windows. But when I move the same JMeter Script into Linux, it failed. Here are some code about my custom listener.</p>
<pre><code>LoggerVisualizer.class
public class LoggerVisualizer extends AbstractVisualizer {
private PerformanceResultCollector collector;
public LoggerVisualizer() {
super();
initConfiguration();
}
private void initConfiguration() {
// some code
}
@Override
public void clearData() {
//some codes
}
public String getStaticLabel() {
return "Performance Logger";
}
public String getLabelResource(){
return "Performance Logger";
}
@Override
public void add(SampleResult sampleResult) {
}
public TestElement createTestElement() {
if (collector == null) {
collector = new PerformanceResultCollector();
}
modifyTestElement(collector);
return collector;
}
}
</code></pre>
<p>PerformanceResultCollector.class</p>
<pre><code>public class PerformanceResultCollector extends ResultCollector implements Serializable {
CustomCollector collector;
public PerformanceResultCollector() {
log.info("construct performance collector")
collector = new CustomCollector();
}
@Override
public void sampleOccurred(SampleEvent e) {
collector.addSample(e.getResult());
}
public void cleanUp(){
CustomCollector.cleanUp();
}
}
</code></pre>
<p>On my Windows server, I add the listener and it works well. I can see the data in the MySQL server. But when I move the script into the Linux and run it with command</p>
<pre><code> nohup ./jmeter -n -t /opt/tests/test.jmx -l /opt/log/perf_result.csv -Jjmeter.save.saveservice.output_format=csv -Jjmeter.save.saveservice.hostname=true -Jjmeter.save.saveservice.print_field_names=false -Jjmeter.save.saveservice.url=true -Jjmeter.save.saveservice.thread_counts=true -Jjmeter.save.saveservice.timestamp_format="yyyy-MM-dd HH:mm:ss" > /opt/log/jmeter_script_run.out 2> /opt/log/jmeter_script_run.err < /dev/null
</code></pre>
<p>And I get the error in jmeter.log like:</p>

<p>In the log, I find that it has alreay come into the construct function of PerformanceResultCollector. But why it throw the NulPointerException. I confirm the lib of jmeter on Linux is same as on Windows. Can anyone tell me what's wrong with my listener? Many thanks</p>
<blockquote>
<p></p>
</blockquote>
<p>After I have modified my code many times, I finally know how to resolve it, even through I don't know the reason. In the PerformanceResultCollector.class, if I construct the lazy CustomCollector, it works.</p>
<pre><code>public class PerformanceResultCollector extends ResultCollector implements Serializable {
CustomCollector collector;
public PerformanceResultCollector() {
log.info("construct performance collector")
}
@Override
public void sampleOccurred(SampleEvent e) {
if (null == collector) {
collector = new CustomCollector();
}
collector.addSample(e.getResult());
}
public void cleanUp(){
CustomCollector.cleanUp();
}
}
</code></pre>
<p>Maybe the JMeter parses the jmx script in different ways for non-gui and gui mode. </p>

Twitter reply-to-mentions bot programmed in Python works once and then crashes with error 400: what is the problem?
|
<p>I´ve been building a bot and it works exactly as intended, but only for one Tweet. Then, it waits 60 seconds, and, if it doesn´t find a new Tweet to reply to (since it´s configured to reply to the most recent Tweet), it throws an error (it´s 400 as in "400: Bad Authentication Data", but I think the issue is not that, since the bot posts on Twitter once without any issues. However, I do think it´s possibly some kind of Bad Request error).
Whenever it crashes, I can just run in my command "python (botname).py" and it works once if there is now a new Tweet, but then, it crashes again.
I want the bot to run properly by itself, so I would really appreciate some help!

Draw/erase button in java

<p>I am struggling to find a way to implement a way that whenever you click a draw button it will decide whether you are drawing or erasing.</p>
<pre><code> private void drawButtonActionPerformed (java.awt.event.ActionEvent evt) {

slider.setEnabled(true);
captureButton.setEnabled(true);

C# Windows Phone 8.1 GetOutputStreamAsync(...) blocking after first use
|
<p>i'm currently trying to create a very basic test app which should:</p>
<p>1) Broadcast "sometext" on port "1234"<br>
2) Wait a second for answers<br>
3) Return all answers </p>
<p>While the solution posted below works fine for the first time, every subsequent call blocks forever at:<br>
<i>stream = await socket.GetOutputStreamAsync(...) </i></p>
<p>Till now i tried every possible way of cleaning up (since thats where i suppose the failure), even wrapping everything in <i>using(...)</i> statements.</p>
<p>The problem occurs with the emulator as well as a hardware device using Windows Phone 8.1</p>

<p>I thoroughly googled and searched about this error and tried such as httpparty, mechanism, fb_graph, and koala.
However those raise same efoerror.
It seems that there is a bug with ruby-1.8.6 or open-uri, but I don't want to upgrade ruby.</p>
<p>Any ideas?

Splitting header and implementation causes significant slow-down
|
<p>When I split the header and implementation in c++, I found that significant slow-down occurs in some situation compared to the header-only one. The minumum working example is like below. In the case below, <code>get_sum</code> function is implemented in the header file and <code>get_sum2</code>, which is exactly the same implementation as <code>get_sum</code>, is implemented in <code>impl.cpp</code>. The result shows that time duration to execute is 0.001 [msec] for <code>get_sum</code> and 1066.84 [msec] for <code>get_sum2</code> (see <code>main.cpp</code>), though both have the same implementation. Could anyone explain why this happens?</p>
<p>The following codes can be found <a href="https://github.com/HiroIshida/snippets/tree/master/cpp/perf_impl_split" rel="nofollow noreferrer">here</a>.</p>

How to boost documents matching one of the query_string
|
<p>Elasticsearch newbie here. I'm trying to lookup documents that has <code>foo</code> in its name but want to prioritize that ones having <code>bar</code> as well i.e. those with <code>bar</code> will be at the top of the list. The result doesn't have the ones with bar at the top. <code>boost</code> here doesn't seem to have any effect, likely I'm not understanding how boost works here. Appreciate any help here.</p>
<pre><code>query: {
bool: {
should: [
{
query_string: {
query: `name:foo*bar*`,
boost: 5
}
},
{
query_string: {
query: `name:*foo*`,
}
}
]
}
}

<p>They both seem to fail because they can't see the method <code>converter</code>. But I am trying to use SFINE and <code>std::enable_if</code> to recognize that this function does not exist and thus only instantiate one of the methods.</p>
<p>The same error is generated for each of the types:</p>

Trying to set different styles on two items from JSON

How to remove parent row and its items in array : jquery
|
<p><strong>Summary:</strong></p>
<p>I am creating a web page which shows results of user selections. First user select items from the given panel and clicks on add button. This creates a table row of selected items of the user(Just like adding items to the cart). User can remove items in the list when remove button is clicked. i am using parents('tr').remove()</p>
<p><strong>Issue:</strong></p>
<p>When the user clicks remove button, the row is getting deleted but the selection items a still in my array "benefits_array".</p>
<p>Here is jquery code:</p>
<pre><code>.on('click','.add-benefits-items', function(e) {
var target = $(this).siblings('.panel-body');
var tree_benefits_text = target.find('#tree-dropdown option:selected').text();
var display_text = target.find('#benefits-display-dropdown option:selected').text();
var unit_text = target.find('benefitsunit.active').text();
var dataset_text = target.find('benefitsDataset.active').text();
var checkboxes = target.find('input[type="checkbox"]');
benefits_array.push(
{
Tree_Benefits : tree_benefits_text,
Display : display_text,
Unit : unit_text,
Dataset: dataset_text,
});
$('.table-benefits').find('tbody')
.each(function(){
var map_elements = '<td style = "text-align:center">';
if (display_text == 'Map') {
map_elements += '<button data-target="#map_btn_benefits_id" type="button" class="map_btn_benefits btn btn-info active" data-toggle="modal">Map</button>';
map_elements += '<div id="map_btn_benefits_id" class="modal fade" role="dialog">';
map_elements += '<div class="modal-dialog"><div class="modal-content"><div class="modal-header"><h4 class="modal-title">Landscape Map</h4></div>';
map_elements += '<div class="modal-body"><div id="map_id_benefits" style="width: 500px; height: 380px; margin: 0; padding: 0;"></div></div>';
map_elements += '<div class="modal-footer"><button type="button" class="save-exit-benefits btn btn-primary" data-dismiss="modal">Save changes and Close</button>';
map_elements += '</div></div></div></div>';
map_elements += '</td>';
}
else {
map_elements += display_text+'</td>';
}
$(this).append(
'<tr>'+
'<td style="text-align:center"><a class="remove-row-benefits text-danger"><i class="fa fa-times"></i></a></td>'+
'<td style="text-align:center">'+tree_benefits_text+'</td>'+
map_elements+
'<td style="text-align:center">'+unit_text+'</td>'+
'<td style="text-align:center">'+dataset_text+'</td>'+
'</tr>')
});
})
.on('click', '.remove-row-benefits', function(){
$(this)
.parents('tr').remove();
})
</code></pre>
<p>I am passing "benefits_array" to other template using django views.py. For this question i believe you do not need code for it. What is the logic i am missing here. </p>

Inner join 3 table
|
<p>I have 6 table in my database <img src="https://i.stack.imgur.com/EzxmW.jpg" alt="booking_system">. And now I would like to inner join car_space, transaction and sport_facilities. However, I got a problem. </p>
<p>When I use these two sql command respectively, these command also can be run and I can get the result I want.</p>
<pre><code>-- car_space INNER JOIN transaction
SELECT * FROM car_space INNER JOIN transaction ON car_space.carSpaceId = transaction.carSpaceId ORDER BY transactionId;
-- sport_facilities INNER JOIN transaction
SELECT * FROM sport_facilities INNER JOIN transaction ON sport_facilities.sportFacilitiesId = transaction.sportFacilitiesId ORDER BY transactionId;
</code></pre>
<p>And then, I combine them into one command.</p>
<pre><code>-- Combine But Not Work
SELECT * FROM transaction
INNER JOIN car_space ON transaction.carSpaceId = car_space.carSpaceId
INNER JOIN sport_facilities ON transaction.sportFacilitiesId = sport_facilities.sportFacilitiesId
ORDER BY transactionId;
</code></pre>
<p>Although this can be run, there are no result or records was shown.</p>
<p>I want to do is the database can be found the record in which table (car_space / sport_facilities) when I typed a transactionId.
For example:
I type <code>WHERE transactionId = 1</code>
Database can be searched this is from sport_facilities table rather that car_space.</p>
<p>Thank you. Here is some code for reference.</p>

How to have type transfer of ChartJS configuration from a react component prop?
|
<p>I made a <code>ChartJS</code> component that is a simple react wrapper to correctly setup and destroy ChartJS instances with some default options:</p>
<pre class="lang-js prettyprint-override"><code>import React, {
useEffect,
useState,
VFC,
} from 'react';
import {
ArcElement,
BarController,
BarElement,
CategoryScale,
Chart,
ChartConfiguration,
DoughnutController,
LinearScale,
} from 'chart.js';
Chart.register(
ArcElement,
BarElement,
BarController,
DoughnutController,
CategoryScale,
LinearScale,
);
export interface ChartJSProps {
config: ChartConfiguration;
}
export const ChartJS: VFC<ChartJSProps> = ({
config,
}) => {
const [id, setId] = useState<string>();
useEffect(() => {
setId(`chart-${Math.floor((1 + Math.random()) * 0x10000).toString(16).substring(1)}`);
}, []);
useEffect(() => {
if (!id) {
return;
}
// @see https://stackoverflow.com/a/58877962/1731473
const canvas: HTMLCanvasElement = document.getElementById(id) as HTMLCanvasElement;
const ctx = canvas.getContext('2d');
let chart: Chart;
if (ctx !== null) {
const { options } = config;
chart = new Chart(ctx, {
...config,
options: {
responsive: true,
maintainAspectRatio: false,
...options,
elements: {
...options?.elements,
line: {
fill: false,
...options?.elements?.line,
},
},
plugins: {
...options?.plugins,
legend: {
display: false,
...options?.plugins?.legend,
},
tooltip: {
mode: 'nearest',
intersect: false,
...options?.plugins?.tooltip,
},
},
},
});
}
return () => {
if (chart) {
// @see https://www.chartjs.org/docs/latest/developers/api.html#destroy
chart.destroy();
}
};
}, [id]);
return (
<canvas id={id} />
);
};
export default null;
</code></pre>
<p>This wrapper is fully working, however, Typescript is yelling about type specific configuration.</p>
<p>Here is a <code>GaugeChart</code> component using the ChartJS <code>doughnut</code> type as an example:</p>
<pre class="lang-js prettyprint-override"><code>import React, {
VFC,
} from 'react';
import { ChartJS } from './ChartJS';
export interface GaugeChartProps {
value: number;
max?: number;
}
export const GaugeChart: VFC<GaugeChartProps> = ({
value,
max = 100,
}) => {
const percent = value / max;
return (
<ChartJS config={{
type: 'doughnut',
data: {
datasets: [
{
backgroundColor: [
'rgb(255, 99, 132)',
'#ccc',
],
// eslint-disable-next-line id-blacklist
data: [
percent * 100,
100 - (percent * 100),
],
},
],
},
options: {
rotation: 270, // start angle in degrees
circumference: 180, // sweep angle in degrees
},
}}
/>
);
};
export default null;
</code></pre>
<p>The <code>npx tsc</code> command give me this:</p>
<pre><code>src/components/chart/GaugeChart.tsx:36:9 - error TS2322: Type '{ rotation: number; circumference: number; }' is not assignable to type '_DeepPartialObject<CoreChartOptions<keyof ChartTypeRegistry> & ElementChartOptions<keyof ChartTypeRegistry> & PluginChartOptions<...> & DatasetChartOptions<...> & ScaleChartOptions<...>>'.
Object literal may only specify known properties, and 'rotation' does not exist in type '_DeepPartialObject<CoreChartOptions<keyof ChartTypeRegistry> & ElementChartOptions<keyof ChartTypeRegistry> & PluginChartOptions<...> & DatasetChartOptions<...> & ScaleChartOptions<...>>'.
36 rotation: 270, // start angle in degrees
~~~~~~~~~~~~~
node_modules/chart.js/types/index.esm.d.ts:3493:3
3493 options?: ChartOptions<TType>;
~~~~~~~
The expected type comes from property 'options' which is declared here on type 'ChartConfiguration<keyof ChartTypeRegistry, (number | ScatterDataPoint | BubbleDataPoint | null)[], unknown>'
</code></pre>
<p>Typescript Version:</p>
<pre><code>❯ npx tsc -v
Version 4.2.2
</code></pre>
<p>As you can see, the <code>rotation</code> option is not recognized.</p>
<p>Of course, I could resolve it by declaring a well typed constant:</p>
<pre class="lang-js prettyprint-override"><code>import React, {
VFC,
} from 'react';
import { ChartConfiguration } from 'chart.js';
import { ChartJS } from './ChartJS';
export const GaugeChart: VFC<GaugeChartProps> = ({
value,
max = 100,
}) => {
const percent = value / max;
const config: ChartConfiguration<'doughnut'> = {
type: 'doughnut',
data: {
datasets: [
{
backgroundColor: [
'rgb(255, 99, 132)',
'#ccc',
],
// eslint-disable-next-line id-blacklist
data: [
percent * 100,
100 - (percent * 100),
],
},
],
},
options: {
rotation: 270, // start angle in degrees
circumference: 180, // sweep angle in degrees
},
};
return <ChartJS config={config} />;
};
</code></pre>
<p>But it means I have to rely directly to the <code>chart.js</code> vendor, it looks not ideal.</p>
<p>Also, the <code>type</code> configuration value should infer to the <code>options</code> defintion, as it is done with a simple <code>new Chart</code> call with direct configuration.</p>
<p>How can I have the same behavior with <code>type</code> value inference on my component wrapper <code>config</code> prop?</p>

Spawning enemies in four different positions with a fixed trajectory in android game
|
<p>This is my first android game, I appreciate all the help. I want to define 4 spawning zones starting from out of the screen (left, right, up and down). Enemies coming from this areas have a fixed trajectory to the center, when this enemies come into the screen the player can move them to a specific corner, but if it lets go of it a new trajectory has to be calculated so it keeps moving to the center.</p>
<p>I am having trouble thinking on how to define this 4 areas, there is also 4 types enemies (they are the same, but they have a different color), should I place this 4 enemies on an arrayList ?. If I know how to define this 4 spawning areas which randomly decides where to spawn I then don't exactly know how to define the fixed trajectory to the center. Also, need to lower the speed to a more adecuate one. (Sorry if this seems like a lot am asking)</p>
<p>Current code looks like this (I am using AndEngine library):</p>

<p>Checking with fiddler shows that multiple requests are made to <code>login.microsoftonline.com</code> and all such requests are successful so I don't think it is the credentials. What could be the problem?</p>

Writing geotiff is grayscale instead of color python-gdal
|
<p>I am trying to upscale an geotiff, using deep learning network. I read in a color geo-tiff using gdal and process each band separately and write that band back into the new geo-tiff driver. The code snippet that does this is given below.</p>
<pre><code> # Remove the scale the image and create separate image for each Band
bands = tiffimg.shape[-1]
#Create TIFF File driver similar to input
driver = gdal.GetDriverByName("GTiff")
outdata = driver.Create(f'{save_dir}/{imgname}.{fileExtension}', tiffDS.RasterXSize*2, tiffDS.RasterYSize*2, bands, gdal.GDT_UInt16)
outpng = np.ones((tiffimg.shape[0]*2,tiffimg.shape[1]*2,tiffimg.shape[2]),dtype=tiffimg.dtype)
for band in range(bands):
singleBand = tiffimg[:,:,band]
bandMaxValue = np.ndarray.max(singleBand)
print(f'Band {band+1} min and max values before processing:{np.ndarray.min(singleBand)} \t {np.ndarray.max(singleBand)}')
scaledBand = (singleBand).astype(np.float32)/bandMaxValue
img_lq = np.stack((scaledBand,)*3,axis=-1)
resizedImg = getSRImage(args, img_lq, imgname) # gets the upscaled band
resizedImg = (resizedImg[:,:,1]*bandMaxValue).round().astype(tiffimg.dtype)
print(f'Band {band+1} min and max values After processing:{np.ndarray.min(resizedImg)} \t {np.ndarray.max(resizedImg)}')
outdata.GetRasterBand(band+1).WriteArray(resizedImg)
outdata.GetRasterBand(band+1).SetNoDataValue(100000)##if you want these values transparent
outpng[band] = resizedImg
outdata.SetGeoTransform(tiffDS.GetGeoTransform())##sets same geotransform as input
outdata.SetProjection(tiffDS.GetProjection())##sets same projection as input
outdata.SetMetadata(tiffDS.GetMetadata())
outdata.FlushCache() ##saves to disk!!
cv2.imwrite(f'{save_dir}/backup/{imgname}.png', outpng[:,:,0:3])
</code></pre>
<p>But as the title suggest the resulting image has all the same characteristics as the parent image (the data type and the number of bands) but when viewing it, the saved image is a gray scale image and not a color image. Not sure where I am going wrong.</p>
<p>Any help is greatly appreciated.</p>
<p>Update 1:
The output of exiftool for the original image is</p>

<p>Solution Update:</p>
<p>As suggested in the comments, the "Photometric interpretation" was the problem. Added "Photometric interpretation=RGB" while creating the driver. which solved the issue.</p>
<pre><code>driver = gdal.GetDriverByName("GTiff")
options = ['PHOTOMETRIC=RGB', 'PROFILE=GeoTIFF']
outdata = driver.Create(f'{save_dir}/{imgname}.{fileExtension}', tiffDS.RasterXSize*2, tiffDS.RasterYSize*2, bands, gdal.GDT_UInt16, options=options)

SwiftUI: NavigationLink weird behaviour
|
<p>I'm trying to build a store in order to navigate in a SwifUI flow.
The idea is that every screen should observe the state and push into the next one using a NavigationLink.</p>
<p>It seems to work for pushing one view, but a soon as I push several views into the stack, it starts behaving oddly: the view pops itself.</p>
<p>Luckily I was able to reproduce it in a separate project. When I move from 2 to 3, the third screen appears but the NavigationView resets to it's original state (<code>ContentView</code>):</p>
<pre><code>import SwiftUI
@main
struct NavigationTestApp: App {
var body: some Scene {
WindowGroup {
NavigationView {
ContentView()
}.navigationViewStyle(StackNavigationViewStyle())
}
}
}
class Store: ObservableObject{
@Published var state: StoreState
struct StoreState {
var flowState: FlowState = .none
}
enum FlowState {
case none, one, two, three
}
enum Action {
case moveTo1, moveTo2, moveTo3
}
init(state: StoreState) {
self.state = state
}
func send(_ action: Action) {
switch action {
case .moveTo1:
state.flowState = .one
case .moveTo2:
state.flowState = .two
case .moveTo3:
state.flowState = .three
}
}
}
struct ContentView: View {
@ObservedObject var store = Store(state: .init())
var body: some View {
VStack {
Button(action: {
store.send(.moveTo1)
}, label: {
Text("moveTo1")
})
NavigationLink(
destination: ContentView1().environmentObject(store),
isActive: Binding(
get: { store.state.flowState == .one },
set: { _ in
}
),
label: {}
)
}
}
}
struct ContentView1: View {
@EnvironmentObject var store: Store
var body: some View {
VStack {

AWS AMI Cleanup w/Ansible iterate through results array
|
<p>I have a previous task that creates weekly backups, labeling them with the server name followed by a date/time tag. The goal of this job is to go in behind it and clean up the old AMI backups, leaving only the last 3. The <code>ec2_ami_find</code> task works fine, but it could also return empty results for some servers and I'd like the deregister task to handle that.</p>
<p>The error I'm getting is pretty generic:</p>
<blockquote>
<p>fatal: [127.0.0.1]: FAILED! => {
"failed": true,
"msg": "The conditional check 'item.ec2_ami_find.exists' failed. The error was: error while evaluating conditional

'ec2_ami_find'\n\nThe error appears to have been in
'/root/ansible/ec2-backups-purge/roles/first_acct/tasks/main.yml': line 25,
column 3, but may\nbe elsewhere in the file depending on the exact
syntax problem.\n\nThe offending line appears to be:\n\n\n- name:

Query the database in foreach results

<p>I'm trying to build a webpage with simple status posts. I've created foreach loop to query the database and load all the posts:</p>
<pre><code> <?php
$user_id = Check::isLoggedIn();
$dbstories = DB::query('SELECT * FROM stories WHERE user_id=:user_id ORDER BY story_time DESC', array(':user_id'=>$user_id));
$post_story = "";

?>
<div>
<article>

<a href="profile.php">

</a>
<div>
<time>
<?php
// to pull post datetime
$post_time = $story['story_time'];
echo '<time class="timeago" datetime="' . $post_time . '"></time>';
?>
</time>
</div>
</div>
</div>
<?php
// to pull post contents
$post_story = $story['story_body'];

</span>
</a>
<!-- the same for comments and shares number goes here -->
</div>
</div>
<div>
<!-- This form over here should pull the story_id which is the post ID from the database like the other queries up there and post it next to the url then that will allow me to use it in isset($_GET['story_id']) and trigger a query to increment likes -->

</article>
</div>
<?php
}
?>
</code></pre>
<p>*Please read the comments within the code</p>
<p>Everything works fine but, I still cant get each post's ID linked to the like button (like_story). It only access the most recent post's ID.</p>
<p>Any workaround to reference the post ID (story_id)?</p>

Firefox html5 validation anomaly with dynamic select options
|
<p>Here is a simple html5 form with two select controls. Changing the selection in the first select generates a new list of options for the second select. Both have the "required" attribute, and an initially selected blank option. The odd bit is that I get a red validation outline around the second select control, without submitting the form. No tool-tip with an error message, just the outline.</p>

<p>fiddle here: <a href="https://jsfiddle.net/afg57g0u/1/" rel="nofollow">https://jsfiddle.net/afg57g0u/1/</a></p>
<p>Run the code, and then select any option in the first select control.
The second lights up red immediately, but the other required controls do not, so it's not validating the whole form, just the second select control (sort-of). </p>
<p>This happens in Firefox 36.0.4. This does not happen on IE 11.0.17, Opera 28.0, Chrome 41.0.2272.101, or Safari 5.1.7 (duh). (on Win8 box)</p>
<p>I can find no other mention online of a similar problem. I have tried numerous approaches to disable or work-around this problem, but no luck.
Does anyone have any ideas? Is this a Firefox bug?</p>

Agile Web Development with Rails 5.1 Playground - Ch 15 Password Trouble
|
<p>I can't figure out something in Agile Web Development with Rails, Chapter 15 - Playgrounds question 1.
It asks <strong>Modify the user update function to require and validate the current
password before allowing a user’s password to be changed.</strong></p>
<p>I really can't understand how I can get the <em>has_secure_password</em> helper method to allow me to also seek the current password, if there is one, and see if it equals a hash before allowing a change of the password to be made.</p>
<p>I'm reading along with the book and when it gets to these Playgrounds, I feel like chewing glass alot of the time.</p>
<p>My _form partial looks like this:</p>
<pre><code><h2>Enter User Details</h2>
<div class="field">
<%= form.label :name, 'Name:' %>
<%= form.text_field :name, id: :user_name, size: 40 %>
</div>
<% if user.password_digest %>
<%= form.label :password_digest, 'Current Password' %>
<%= form.password_field :password_digest, id: :password_digest, size: 40 %>
<% end %>
<div class="field">
<%= form.label :password, 'Password' %>
<%= form.password_field :password, id: :user_password, size: 40 %>
</div>
<div class="field">
<%= form.label :password_confirmation, 'Confirm:' %>
<%= form.password_field :password_confirmation,
id: :user_password_confirmation,
size: 40 %>
</div>
<div class="actions">
<%= form.submit %>
</div>
</code></pre>
<p>I check whether the user at present has a password_digest property in the the instance-variable to see whether I display the form chunk that is all decked out with password_digest symbols.</p>
<p>In my user_controller's <strong>update</strong> function, looks like this</p>
<pre><code>def update
puts "update running"
puts @user
puts @user.name
puts @user.password
puts @user.password_confirmation
respond_to do |format|
if @user.update(update_params)
# format.html { redirect_to @user, notice: 'User was successfully updated.' }
format.html { redirect_to users_url, notice: "User #{@user.name} was successfully updated." }
format.json { render :show, status: :ok, location: @user }
else
format.html { render :edit }
format.json { render json: @user.errors, status: :unprocessable_entity }
end
end
end
</code></pre>
<p>You'll notice the use of 'update_params'...I made another private method at the bottom of the file that differs from the standard 'user_params', I thought by substituting that into the mix I could get the whole thing to work.</p>
<p>To be honest, I'm so incredibly lost. If someone could please guide me on how to do this, I would be really grateful. I've googled and stackflow searched all over and I feel like in the search to find water to douse fire, I can only find flammable liquids, each one more reactive to heat than the last.</p>
<p>Is there a repository out there that has all these extra 'Playgrounds' things done, so I can take a look at them and see what's going on?</p>

Getting a 403 when calling Azure Resource Rate API using certificate auth

<p>I am trying to create a console app that can call the <a href="https://msdn.microsoft.com/en-us/library/azure/mt219004" rel="nofollow noreferrer">Azure Resource Rate API</a> using certificate authentication. For this, I used the following branch <a href="https://github.com/HarvestingClouds/billing-dotnet-ratecard-api" rel="nofollow noreferrer">GitHub link</a>.</p>
<p>I am getting a 403 error. I've added an Web App to my Azure AD. In the manifest, I've copied the key credentials from the certificate I've signed using the following PowerShell commands;</p>

$base64Thumbprint = [System.Convert]::ToBase64String($bin)
$keyid = [System.Guid]::NewGuid().ToString()

R shiny: slickROutput disappears when switching tabpanel()
|
<p>I am making a <code>Shiny</code> app with <code>tabPanels</code> embedded in a <code>navbarPage</code>.
In each <code>tabPanel</code>, I generate a serie of image. When switching from one panel to the other one, the image loaded in one of them disappear.</p>
<p>I have to "refresh" manually the page to see it again. The problem seems similar than the one posted <a href="https://stackoverflow.com/questions/51380071/keep-plots-and-input-values-when-switching-between-tabs">here</a> but I cannot really subset my <code>tabPanels</code>, even though I gave <code>$id</code> and <code>value</code> to them.</p>
<p>Here is a reproducible example:</p>
<pre><code>library(shiny)
library(shinythemes)
library(slickR)

WPF elements are in visual tree, but not animated?
|
<p>I'm trying to figure out how to generate animations procedurally. I create a Line, create four animations, and associate the line's endpoints to the animations. I add the animations to a storyboard, then I run the storyboard.</p>
<p>The panel itself is visible (I could change the background orange, and that change shows up), but not its children. The heck am I doing wrong? </p>
<p>Code behind:</p>
<pre><code>using System.Windows.Controls;
using System.Windows.Media;
using System.Windows.Shapes;
using System.Windows.Media.Animation;
namespace MyProject.Animations
{
public class MyAnimation : Panel
{
private DoubleAnimation[] lineAnimation;
private Line line;
private Storyboard storyboard;
public MyAnimation()
{
storyboard = new Storyboard();
line = new Line();
line.StrokeThickness = 4;
line.Stroke = Brushes.Black;
this.Children.Add(line);
lineAnimation = new DoubleAnimation[4];
for (int i = 0; i < 4; i++)
{
lineAnimation[i] = new DoubleAnimation();
lineAnimation[i].Duration = new Duration(TimeSpan.FromSeconds(5));
lineAnimation[i].AutoReverse = true;
lineAnimation[i].RepeatBehavior = RepeatBehavior.Forever;
lineAnimation[i].From = 10 * i;
lineAnimation[i].To = 100 * i;
storyboard.Children.Add(lineAnimation[i]);
}
Storyboard.SetTarget(lineAnimation[0], line);
Storyboard.SetTargetProperty(lineAnimation[0], new PropertyPath("X1"));
Storyboard.SetTarget(lineAnimation[1], line);
Storyboard.SetTargetProperty(lineAnimation[1], new PropertyPath("Y1"));
Storyboard.SetTarget(lineAnimation[2], line);
Storyboard.SetTargetProperty(lineAnimation[2], new PropertyPath("X2"));
Storyboard.SetTarget(lineAnimation[3], line);
Storyboard.SetTargetProperty(lineAnimation[3], new PropertyPath("Y2"));
storyboard.Begin();
}

React: override internal components with custom component
|
<p>I have a modal that is completely self contained. The modal is opened via going to the modal route and all the functionality to close the modal from button or outside clicks is within the modal component. Basically the modal is not controlled by any parent passing state. I was given a task of making the modals button customizable, meaning passing in a new button component, so we can add the modal to our lib instead of copy pasting the code in projects. Lol this seemed simple enough, and maybe it is and I am just overthinking this.</p>
<p>I cant paste the actual code but I can use a contrived example. This is a very simplified version of the modal, keeping in mind it opens via route so there's really no state and setState in the actual code. Also here is a <a href="https://jsfiddle.net/aaronbalthaser/af5p2kvj/73/" rel="nofollow noreferrer">fiddle</a></p>
<pre><code>const ModalHeader = ({ onClose }) => {
return (
<div className="modal__header">
<button
className="modal__close-btn"
data-testid="modal-close-button"
onClick={onClose}
/>
</div>
);
};
const Modal = ({ children }) => {
const [state, setState] = React.useState(true);
const handleCloseOutsideClick = () => {
setState(false);
};
const handleCloseButtonClick = () => {
setState(false);
};
const renderModal = () => {
return (
<div className="modal-overlay" onClick={handleCloseOutsideClick}>
<div className="modal">
<ModalHeader onClose={handleCloseButtonClick} />
{children}
</div>
</div>
);
};
return state ? renderModal() : null;
};
const App = () => {
return (
<Modal>
<div>Modal Children</div>
</Modal>
);
};
ReactDOM.render(<App />, document.querySelector('#app'));
</code></pre>
<p>I tried a few things, initially I attempted to find a way to pass in a new header component containing a button. Then as I got into the code I realized what I was doing would lose the self contained functionality of the modal. My approach was along the lines of below but obviously the onClick would be an issue since invoking the close functionality is internal.</p>
<p>So I tried using cloneElement to add props within the component if the custom header was detected:</p>
<pre><code>// inside modal component
React.useEffect(() => {
React.Children.map(children, (child: React.ReactElement) => {
if (child && child.type === ModalHeader) {
setHederFound(true);
}
});
}, []);
// inside modal render:
<div className={modalClasses} onClick={stopPropagation}>
{!headerFound ? (
<ModalDefaultHeader onClose={handleCloseButtonClick} />
) : (
React.Children.map(children, (child: React.ReactElement) => {
if (child && child.type === ModalHeader) {
return React.cloneElement(child, {
onClose: handleCloseButtonClick,
});
}
})
)}
{children}
</div>;
</code></pre>
<p>Obviously that did not work because there's no onClick in the custom button. Anyways I am thinking that I am over complicating this. I just need a way to pass in a custom button while leaving the functionality internal to the modal. Any assistance would be appreciated.</p>
<p>Thanks in advance.</p>

Passing DateTime variable to controller causing an error
|
<p>I am building a small prediction feature into my application. Running into an issue which I cannot seem to understand. I am calculating some basic results and returning a Dictionary containing the 2 results. Thought this would be a good way to get back both results from one function instead of calling two. I have found some proposed solutions for this error such as converting the DateTime to a string but this did not work for me either. Would appreciate any insight into the cause of the error. Thanks in advance.</p>

notifyDataSetChanged() not updating RecyclerView Adapter
|
<p>I am working on a very simple implementation of a RecyclerView that displays data stored in a ViewModel. I am still very new to Android development and am trying to learn the fundamentals. In this situation, all the data to be stored in the ViewModel is stored in a simple list, later on I want to use Room to do this but right now I am struggling to get things working. Currently adding an item to the list only adds that item to the private member (_mainList) of the ViewModel, the public member (mainList) is unchanged, and this is the member passed into the adapter constructor call.</p>
<p>ViewModel:</p>
<pre><code>class ListViewModel : ViewModel() {
private val _mainList = mutableListOf<String>()
val mainList = _mainList.toList()
fun addMainListItem(item: String) {
_mainList.add(item)
}
}
</code></pre>
<p>Adapter:</p>
<pre><code>class MainAdapter(private var list: List<String>) :
RecyclerView.Adapter<MainAdapter.ViewHolder>() {
class ViewHolder(view: View) : RecyclerView.ViewHolder(view)
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
val view = LayoutInflater.from(parent.context).inflate(R.layout.list_item, parent, false)
return ViewHolder(view)
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
holder.itemView.list_item_text.text = list[position]
}
override fun getItemCount(): Int {
return list.size
}
}
</code></pre>
<p>Fragment that displays the list:</p>
<pre><code>class MainListFragment : Fragment() {
private val viewModel: ListViewModel by activityViewModels()
private var _binding: FragmentMainListBinding? = null
private val binding get() = _binding!!
lateinit var adapter: MainAdapter
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View {
_binding = FragmentMainListBinding.inflate(inflater, container, false)
val root: View = binding.root
return root
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
// Add click listener to floating action button
binding.fabMain.setOnClickListener {
addListItem()
}

How do I create a function that will return a value in a dictionary for each row within a data sheet using Python?

<p>I need to create a new column in my table for a state region that populates a region for every row of data (each having a state). How do I write a function to call upon a dictionary for each row item?</p>
<p>I have about 30,000 row items, and I believe a loop would take too long. I am certain there is some way to do this with dictionaries. I've tried using different methods to call this but cannot seem to get it to populate the correct data.</p>

Binding column width programmatically in UWP?
|
<p>I am trying to create columns that can be resized by the user during runtime just like in excel. However, I am creating fields dynamically and don't know how to bind the programmatically created column's width to the width of my column created in xaml.</p>
<p>Question: How can I bind column width programmatically rather than in the XAML?</p>
<p>cs:</p>
<pre><code>public sealed partial class WepPage : Page
{
static int i = 0;
Grid grid;
public WepPage()
{
this.InitializeComponent();
}
private void AddWepButton_Click(object sender, RoutedEventArgs e)
{
addWepStack();
}
private void addWepStack()
{
grid = new Grid();
grid.Name = ("ItemGrid" + i.ToString());
WepStackPanel.Children.Add(grid);
//create columns
ColumnDefinition col0 = new ColumnDefinition();
ColumnDefinition col1 = new ColumnDefinition();
ColumnDefinition col2 = new ColumnDefinition();
ColumnDefinition col3 = new ColumnDefinition();
ColumnDefinition col4 = new ColumnDefinition();
ColumnDefinition col5 = new ColumnDefinition();
// Set the width of each column
//HERE IS WHERE I WANT TO BIND THE COLUMN WIDTH TO THE WIDTH OF THE HEADERS
//SO THE USERS CAN CHANGE THE COLUMN WIDTH WHILE THE APPLICATION IS RUNNING.
// Add columns to grid
grid.ColumnDefinitions.Add(col0);
grid.ColumnDefinitions.Add(col1);
grid.ColumnDefinitions.Add(col2);
grid.ColumnDefinitions.Add(col3);
grid.ColumnDefinitions.Add(col4);
grid.ColumnDefinitions.Add(col5);
i++;

<p>I have a problem with android a <code>ViewPager</code> setup with <code>FragmentPagerAdapter</code> and <code>TabLayout</code> </p>

Getting the check changed event for a dynamically created Radio Group within a ListView
|
<p>We are working on a project where there is a questionnaire with dynamically created radio groups with radio buttons.At the bottom of the listview we have placed a button and we need the selected values from the radio buttons on clicking the button.<strong>The issue is how to get the selected Radio button values.Also i wanted to know in which class i can get the values in the main activity or in the Base Adapter class?</strong></p>
<p>We have done the following:</p>
<p>The main activity:</p>
<pre><code>submit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
for(m=0;m<question_list_array.size();m++)
{
View view= question_list.getChildAt(m);
RadioGroup radioGroup= (RadioGroup) view.findViewById(R.id.single_radiogroup);
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
for(int n=0;n<group.getChildCount();n++)
{
RadioButton rb= (RadioButton) group.getChildAt(n);
if (rb.getId() == checkedId) {
String result= rb.getText()+"";
Toast.makeText(MainActivity.this,result, Toast.LENGTH_LONG).show();
// do something with text
return;
}
}
}
});
}
}
});
</code></pre>
<p>But i am getting NPE at the following line:</p>
<pre><code>RadioGroup radioGroup= (RadioGroup) view.findViewById(R.id.single_radiogroup);
</code></pre>
<p>The adapter class:</p>
<pre><code>@Override
public View getView(int position, View convertView, ViewGroup parent) {
String question_type = question_list_array.get(position).getQuestion_type();
option_list = question_list_array.get(position).option_list;
number_of_options = option_list.size();
v_single=convertView;
if (v_single == null) {
v_single = inflater.inflate(R.layout.single_choice_layout, null);
sh = new SingleHolder();
sh.single_question_name = (TextView) v_single.findViewById(R.id.single_question_name);
sh.single_radiogroup = (RadioGroup) v_single.findViewById(R.id.single_radiogroup);
v_single.setTag(sh);
}
else
{
sh = (SingleHolder) v_single.getTag();
}
sh.single_radiogroup.clearCheck();
sh.single_radiogroup.removeAllViews();
sh.single_question_name.setText(question_list_array.get(position).getQuestion_name());
for (int j = 0; j < number_of_options; j++)
{
RadioButton rb = new RadioButton(context);
rb.setText(option_list.get(j).getOption_name());
sh.single_radiogroup.addView(rb);
}
v_final=v_single;
return v_final;
}
</code></pre>
<p>We dont have any issues with the Adapter as such.Please reply at the earliest.</p>

HTMLEditorExtender inside a repeater - buttons not rendering correctly
|
<p>I have a <code>HTMLEditorExtender</code> inside a repeater:</p>
<pre><code><asp:Repeater ID="rptEditItem" runat="server">
<HeaderTemplate>
<table border="0" style="width: 100%" class="DefaultText">
</HeaderTemplate>
<ItemTemplate>
<tr>
<td>
<div class="containerClass">
<asp:TextBox ID="txtEdit" runat="server" TextMode="MultiLine" Text='<%# Eval("DisplayText") %>' Height="300px" Width="600px"></asp:TextBox>
<asp:HtmlEditorExtender ID="HtmlEditorExtender1" DisplaySourceTab="true" TargetControlID="txtEdit" EnableSanitization="false" runat="server" >
</asp:HtmlEditorExtender>
</div>
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
</code></pre>
<p>However the buttons are rendeing without the icons. How can I resolve this?</p>
<p><img src="https://i.stack.imgur.com/f3UMv.png" alt="HTMLExtender Example"></p>
<p><strong>Edit</strong></p>
<p>I was able to work around this issue by placing another <code>HtmlEditorExtender</code> and <code>TextBox</code> outside the repeater and hide it with jquery.</p>
<pre><code><div id="hideme">
<asp:TextBox ID="txtEdit2" runat="server" TextMode="MultiLine" Height="0px" Width="0px"></asp:TextBox>
<asp:HtmlEditorExtender ID="HtmlEditorExtender1" DisplaySourceTab="false" TargetControlID="txtEdit2" EnableSanitization="false" runat="server">
</asp:HtmlEditorExtender>
</div>
</code></pre>
<p>Jquery:</p>
<pre><code><script type="text/javascript" src="Scripts/jquery-1.4.1.min.js"></script>
<script type="text/javascript">
function pageLoad() {
hideFalseEditor();
}
function hideFalseEditor(sender, args) {
$(document).ready(function () {
$('#hideme').hide();
});
}
</script>
</code></pre>
<p>This seems a bit odd, but works. Perhaps a better solution?</p>

How to pan and zoom svg file in shiny app

Processing touches on moving/ animating UiViews
|
<p>I currently have the problem that touches are not always identified correctly,
My goal is to have 3 gestures,The 3 gestures are</p>
<ol>
<li>A user can tap on a view and the tap gets recognised,</li>
<li>A user can double tap on a view and the double tap is recognised,</li>
<li>A user can move their finger on the screen and if a view is below it
a tab is recognised.</li>
</ol>
<p>However I have multiple views all animating constantly and they may overlap,
Currently I sort views by size and have the smallest views on top of larger views.
And I typically get an issue that UIViews are not recognised when tapping on them. In particular double taps, swiping seems to work fine most of the time however the whole experience is very inconsistent.</p>
<p>The current code I'm using to solve the problem is:</p>

How to add a word per minute calculator to a website using Javascript, html, or css?
|
<p>Iv'e been trying to complete a typing test website for some time and am stuck on how to add a word per minute counter. I have tried multiple ways but none of them work. What I want it do do is give the words per minute after the user types a prompt correctly.
Code is below:</p>
<p>HTML:</p>
<pre><code><!DOCTYPE html>

When using Google's Cloud Speech and sending Speech Contexts the returned transcriptions are not returning expected results

<p>We are having an issue where certain words added in the user's speech context are not being returned or prioritized. </p>
<p>When using phrase hints, the API will generally correctly transcribe the phrases or words supplied when uttered, however some words will not be transcribed no matter how you add them in phrase hints.</p>

<p>Separating the phrase hints and only sending one of them has no effect on the result.</p>

We can't do account linking using iOS's Google assistant app
|
<p>I want to realize account linking to Google account with Google Home.
On realizing this, our app's flow of account linking follow to
<a href="https://stackoverflow.com/questions/50931590/google-home-authorization-code-and-authentication-with-google-account/50932537#50932537">this page</a>.<br></p>
<p>It page shows this.</p>
<blockquote>
<ol start="6">
<li>...so we send back a message saying they need to visit our website to authorize us to access their Google services. We may require them to switch to a mobile device to do this part and even include a link to the login page.</li>
</ol>
</blockquote>
<p>At this part, we use <a href="https://developers.google.com/assistant/conversational/df-asdk/rich-responses" rel="nofollow noreferrer">GoogleHome's rich response</a> to send authentication link to user's mobile device.<br>
For example,</p>
<pre><code> payload: {
google: {
expectUserResponse: true,
richResponse: {

simpleResponse: {

}
},
{

}
}
],
}
}
]
}
}
}
</code></pre>
<p>We can do account linking using Android OS, but iOS can't do that due to 403 error.
We've investigated <a href="https://developers.googleblog.com/2016/08/modernizing-oauth-interactions-in-native-apps.html" rel="nofollow noreferrer">the cause</a>, it needs to use a specific browser to see google authentication page.</p>
<p><strong>How can I do account linking to avoid such problem?<br>
Or could you tell me another way to do account linking to Google account.</strong></p>
<p>Please excuse my poor English. Thank you.</p>

Regex Date and Time Delimitter and Sort
|
<p>My logs are getting stored in multiple Sun based unix servers.</p>
<p>So logs of Req1 might be in server1, Req2 and Req3 might be in server2 and then Req4 could be in server1 again. There is no proper sequence as it is stored based on what load balancer decides.</p>
<p>We use grep to get the data from all the servers. But problem is they are not sorted based on the time. What I want is to get the log file from all the servers as below but sort it based on the date and time.</p>
<p><strong>Edit</strong>
Here is example for the question.</p>
<pre><code>for (( i=1; i<=24; i++ )) do
echo 'server1' $logfile $i
grep abd12453 /var/logs/$i.log
echo 'server2' $logfile $i
ssh server2 "grep 'abd12453' /var/logs/$i.log"
done
</code></pre>
<p>where abd12453 is the user based on which the log will be extracted.</p>
<p>The above commands combines logs of all files of both server and print it. like below.</p>
<pre><code>server1 logfile1.log

What kind of CSS positioning can I use that isn't going to have (many) side effects?
|
<p>I'm currently building a website and and I can't find a CSS positioning method that works, meaning any CSS positioning element that doesn't make other HTML elements behave weirdly. Is there any CSS positioning methods that would position an HTML element precisely, accurately and not cause (many) issues with other elements? So far <code>float</code> and <code>position: absolute;</code> don't work well. Thanks!</p>
<p>Since apparently what I'm asking is unclear, I'm asking "What kind of positioning can I use that doesn't have any (or few) side effects?"</p>

Canvas returns blank image
|
<p>I have simply a button 'Create screenshot' and live stream 'rtsp-relay'. When that button is cliked it should take a snapshot or screenshot and show that under image, my problem is it shows blank image, i have tried to do this in two ways and both of them show blank image (live stream works fine).</p>
<p>code works fine with a simple drawing on a canvas:

passing values to bootstrap modal
|
<p>I am trying to pass values to my <code>modal</code> in html using <code>JQUERY</code>.</p>
<p>I have this:</p>
<pre><code><a class="dropdown-item" href="javascript:void(0);" data-toggle="modal" data-target="#clientStatus" data-clientCurrentStatus="inactive">Change Client Status</a>
<script>
$(function() {
$('#clientStatus').on('show.bs.modal', function(event) {
var button = $(event.relatedTarget); // Button that triggered the modal
var clientCurrentStatus = button.data('clientCurrentStatus'); // Extract info from data-* attributes
// If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
// Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
var modal = $(this);
modal.find('#clientCurrentStatus').val(clientCurrentStatus);
});
});
</script>
</code></pre>
<p>and what I am trying to do is inside <code>data-clientCurrentStatus</code> i am passing the value. and then inside my <code>modal</code> I have this:</p>
<pre><code><div class="modal fade" id="clientStatus" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabelLogout"
aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabelLogout">Update Client Status</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">&times;</span>
</button>
</div>
<div class="modal-body">
<p>Current Status:</p>
<input type="text" name="clientCurrentStatus" id="clientCurrentStatus">
</div>
<div class="modal-footer">
<button type="button" class="btn btn-outline-primary" data-dismiss="modal">Cancel</button>
<a href="/logout" class="btn btn-primary">Logout</a>
</div>
</div>
</div>
</div>
</code></pre>
<p>so as you can see, the <code>id</code> matches, and everything matches. I am not sure why it isn't working. I am importing the <code>jquery</code> tag like this:</p>
<pre><code><script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
</code></pre>
<p>but nothing is working. how can i fix this?</p>

create , publish vuejs component on npm using vue/cli version 4 and use it in typescript based class style vuejs project
|
<p>i am learning vuejs and i am using latest versions of it like vue/cli version 4.x.x and now i want to perform a task which is like:</p>
<ol>
<li><p>I need to create a simple header using vue/cli version 4.x.x which will take an array inside headers variable as a
props.</p>
</li>
<li><p>Now, i want to publish it over npm.</p>
</li>
<li><p>Next i will be creating another vue project which will be using typescript and as a class based style and use my npm package create in 2nd step in this project.</p>
</li>
</ol>
<p>i have followed several articles to complete this approach. link of which is mentioned below

<p>Even though i am able to create header and publish it over npm but i am unable to use that npm package at all it gives the error.</p>
<blockquote>

<p><a href="https://i.stack.imgur.com/FgfFm.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FgfFm.png" alt="enter image description here" /></a></p>
<p>Now its giving me an error that</p>
<blockquote>
<p>Could not find a declaration file for module 'header-bell'. 'd:/Alok/Work/References/interceptor-boilerplate/node_modules/header-bell/dist/headercomponent.umd.js' implicitly has an 'any' type.
Try <code>npm install @types/header-bell</code> if it exists or add a new declaration (.d.ts) file containing `declare module 'header-bell';</p>
</blockquote>
