How to terminate thread using condition returned by wx.CallAfter()?
|
<p>I am very new to wxPython and also not familiar with thread concept. I would appreciate a lot if anyone could provide info sources or suggestion to my question. </p>
<p>I had created a GUI using wxpython to allow users run my script with inputs. Since one step takes 20 min to run so I plan to create a Progress Dialog to show users progress and allow them to abort it. I had tested this using the sample code below. </p>
<p>However, I couldn't stop WorkThread even though I clicked the Stop Button in Progress Dialog. I tried
1. make if statement using return value from pb.sendMessage()
2. create the ProgressDialog object when WorkThread starts and call ProgressDialog.abort
but none of them work. I wonder if there's conceptual mistakes implementing code like this to achieve what I want to do? Or if this can work with correction? Any hint would be appreciated!!</p>

pod spec lint fails with 400

<p>I followed all the steps from <a href="https://guides.cocoapods.org/making/using-pod-lib-create" rel="nofollow noreferrer">https://guides.cocoapods.org/making/using-pod-lib-create</a> to make my openSource library available on cocoapds.
At the end of the steps before publishing run <code>pod lib lint</code> command and it passed the test:</p>

<p><strong>EDIT 1:</strong></p>
<p>It turns out i didn't create a tag at my Github repo. I created tag with the version <code>0.1.0</code> and run <code>pod spec lint SHMultipleSelect.podspec</code> command again. Now it's giving me another error:</p>

Loop breaks after certain amount of iteration

<p>I've a job to do some migration on wordpress sites, although I don't think wordpress has anything to do with my problem.
So I'm getting a set of data from a table (id, value) which is serialized. </p>
<p>I want to put the serialized data into arrays, according to the function. The algorithm doing everything fine for the first 86 records.</p>
<p>If I run the algorithm on just 86 records I get all the right data instantly. But when I run it 87 or more times its just goes into loading. Doesn't matter how long the max execution time limit is it's still gonna reach it apparently. </p>
<p>I checked the 87th record if theres something odd with it, but nothing i can see. Is there any idea what could couse this?</p>
<p>Here's the code:</p>
<pre><code>global $wpdb;
$houses_built_years = $wpdb->get_results('SELECT post_id, meta_value FROM bp100_postmeta WHERE meta_key = "epites_eve"');
foreach ($houses_built_years as $house_built_years) {
if ($house_built_years->meta_value) {
$years = unserialize($house_built_years->meta_value);
} else {
continue;
}
$build = array(array());
$series = 0; $year = 0;
while (count($years)) {
if ($build[$series][$year] && (min($years) - $build[$series][$year] == 1)) {
$year++;
$build[$series][$year] = min($years);
unset($years[array_search(min($years), $years)]);
} else if ($build[$series][$year]) {
$year = 0;
$series++;
$build[$series][$year] = min($years);
unset($years[array_search(min($years), $years)]);
} else {
$build[$series][$year] = min($years);
unset($years[array_search(min($years), $years)]);
}
}
$repeater = array();
foreach ($build as $series) {
if (count($series) > 1) {
$repeater[] = $series[0] . ' - ' . $series[count($series) - 1];
} else {
$repeater[] = $series[0];
}
}
}
</code></pre>
<p>Here's some example of records (algoithm breaking at id = 30517):</p>

The problems is when I draw a circle with all those buttons included in the file it's never a smooth circle it's full of corners like hexagon shape but when I exclude buttons may be leaving in one or two, it draws a perfect smooth circle. I have tried to split the file into three so I've included them using but still same result. Can someone please enlighten me what am I do wrong.</p>

Need help writing a function for summary_table(dplyr::group_by
|
<p>I am trying to create a function that will minimize the number of times I will have to calculate all of the stats individually (Min, Median, Max, Mean, SD, and NAs). I have included the first two pieces of this large list, and how the list is being used. </p>
<pre><code> list("Child Age" =
list("Min" = ~ min(.data$ChildAge,na_rm = TRUE),
"Median" = ~ median(.data$ChildAge,na_rm = TRUE),
"Mean &plusmn; SD" = ~ qwraps2::mean_sd(.data$ChildAge,na_rm = TRUE),
"Max" = ~ max(.data$ChildAge,na_rm = TRUE),
"NA (Not factored in analysis)" = ~ percent(sum(is.na(.data$ChildAge)) /length(.data$ChildAge))),
"Child Gender" =
list("Girl" = ~ qwraps2::n_perc(.data$ChildGender == "Girl", na_rm = TRUE),
"Boy" = ~ qwraps2::n_perc(.data$ChildGender == "Boy", na_rm = TRUE))
......
by_clinic_demographic <- summary_table(dplyr::group_by(df, Clinic), demographic_summary)
by_clinic_demographic
</code></pre>
<p>I have tried to design a function that will work:</p>
<pre><code>analysis_func <- function(x=df$StudyID) {
list1 <- list("Min" = min(x,na.rm = TRUE),
"Median" = median(x,na.rm = TRUE),
"Mean &plusmn; SD" = qwraps2::mean_sd(x,na_rm = TRUE),
"Max" = max(x,na.rm = TRUE),
"NA (Not factored in analysis)" = percent(sum(is.na(x)) /length(x)))
#str(list1)
return(list1)
}
</code></pre>
<p>When I then go to call this function in a new list:</p>
<pre><code>assessment_summary <-
list("Mother Age" = analysis_func(.data$MotherAge),,
</code></pre>
<p>I get the error: <strong>Error: <code>x</code> must be a formula</strong></p>
<p>When I add ~ after the = sign, so for example:</p>
<pre><code>"Min" = ~ min(x,na.rm = TRUE)
</code></pre>
<p>I then get the error: <strong>Error in FUN(X[[i]], ...) : only defined on a data frame with all numeric variables</strong></p>
<p>Here is a simplified version to highlight the issue that I am having:</p>
<pre><code>analysis_func <- function(x=df$StudyID) {
list1 <- list("Min" = ~ min(x,na.rm = TRUE),
"Median" = ~ median(x,na.rm = TRUE),
"Mean &plusmn; SD" = ~ qwraps2::mean_sd(x,na_rm = TRUE),
"Max" = ~ max(x,na.rm = TRUE),
"NA (Not factored in analysis)" = ~ percent(sum(is.na(x)) /length(x)))
return(list1)
}
test_summary <-
list("Scores" = analysis_func(.data$StudyID))
# test_stack <- summary_table(dplyr::group_by(dataframe, s), test_summary)
# test_stack
n = c(2, 3, 5, 4,10,12,rep(10,4))
s = c(rep("aa",5),rep("bb",5))
dataframe <- data.frame (n,s)
test_summary2 <-
list("Scores" =
list("Min" = ~ min(.data$n,na_rm = TRUE),
"Median" = ~ median(.data$n,na_rm = TRUE),
"Mean &plusmn; SD" = ~ qwraps2::mean_sd(.data$n,na_rm = TRUE),

how to retrieve XML data using XPath which has a default namespace in Java?
|
<p>I've come across and problem that I've looked up on stack overflow but none of the solutions seems to solve the problem for me.</p>
<p>I'm retrieving XML data from Yahoo and it comes back as below (truncated for brevity's sake).</p>
<pre><code><?xml version="1.0" encoding="UTF-8" standalone="no"?>
<fantasy_content xmlns="http://fantasysports.yahooapis.com/fantasy/v2/base.rng" xmlns:yahoo="http://www.yahooapis.com/v1/base.rng" copyright="Data provided by Yahoo! and STATS, LLC" refresh_rate="31" time="55.814027786255ms" xml:lang="en-US" yahoo:uri="http://fantasysports.yahooapis.com/fantasy/v2/league/328.l.108462/settings">
<league>
<league_key>328.l.108462</league_key>
<league_id>108462</league_id>
<draft_status>postdraft</draft_status>
</league>
</fantasy_content>
</code></pre>
<p>I've been having a problem getting XPath to retrieve any elements so I've written a unit test to try to resolve it and it looks like:</p>
<pre><code> final File file = new File("league-settings.xml");
javax.xml.parsers.DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
dbFactory.setNamespaceAware(true);
javax.xml.parsers.DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
org.w3c.dom.Document doc = dBuilder.parse(file);
javax.xml.xpath.XPath xPath = XPathFactory.newInstance().newXPath();
xPath.setNamespaceContext(new YahooNamespaceContext());
final String expression = "yfs:league";
final XPathExpression expr = xPath.compile(expression);
Object nodes = expr.evaluate(doc, XPathConstants.NODESET);
assert(nodes instanceof NodeList);
NodeList leagueNodes = (NodeList)nodes;
int leaguesLength = leagueNodes.getLength();
assertEquals(leaguesLength, 1);
</code></pre>
<p>The YahooNamespaceContext class I created to map the namespaces looks as follows:</p>
<pre><code>public class YahooNamespaceContext implements NamespaceContext {
public static final String YAHOO_NS = "http://www.yahooapis.com/v1/base.rng";
public static final String DEFAULT_NS = "http://fantasysports.yahooapis.com/fantasy/v2/base.rng";
public static final String YAHOO_PREFIX = "yahoo";
public static final String DEFAULT_PREFIX = "yfs";
private final Map<String, String> namespaceMap = new HashMap<String, String>();
public YahooNamespaceContext() {
namespaceMap.put(DEFAULT_PREFIX, DEFAULT_NS);
namespaceMap.put(YAHOO_PREFIX, YAHOO_NS);
}
public String getNamespaceURI(String prefix) {
return namespaceMap.get(prefix);
}
public String getPrefix(String uri) {
throw new UnsupportedOperationException();
}
public Iterator<String> getPrefixes(String uri) {
throw new UnsupportedOperationException();
}
}
</code></pre>
<p>Any help with people with more experience with XML namespaces or debugging tips into Xpath compilation/evaluation would be appreciated.</p>

SQL Server : Group By records not on the same day
|
<p>I have a set of tables where we used to maintain transaction histories of bank account.</p>
<p>We have applied grouping on the transaction and get the grouped transactions. This worked fine for normal accounts. I used this query to analyze the users regular transactions which happens on pattern like every week or fortnightly or monthly and it is used to to find the users Salary credit, and living expenses.</p>
<p>When the transactions are based on joint account and if a patterned transaction happens on the same day with same description, the query sums up which is wrong.</p>
<p>Ex:</p>
<p>Husband & Wife works on the same company and gets Salary on 1000 & 500 respectively. The grouping should group 1000 separately and 500 separately. The transaction amount can differ because he or she could get variable pay. Because of this issue, it is calculate pattern wrong. Say if the its fortnightly, it calculates as weekly. Can someone shed some idea to fix this issue.</p>
<p>The requirement is, if a group occurs twice in the same day, it should group them separately.</p>
<p>SCHEMA</p>
<pre><code>1. CustomerBankAccountTransactions

I read something about this and it said to reduce the batch size. How to reduce it?
Is it because the .tif file is around 100 MB?

Scope 'session' is not active for the current thread while accessing Spring session bean inside RxJava thread
|
<p>I'm getting an exception while trying to access a Spring session scoped bean inside a thread of rxjava Schedulers.io()</p>
<pre><code>Caused by: java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.
</code></pre>
<p>Here is my scoped bean</p>
<pre><code>@Component
@Scope(value = WebApplicationContext.SCOPE_SESSION, proxyMode = ScopedProxyMode.TARGET_CLASS)
@Getter
@Setter
public class SearchSession {
List<String> results;
}
</code></pre>
<p>And my controller</p>
<pre><code>@Controller
@AllArgsConstructor(onConstructor=@__(@Autowired))
@Slf4j
public class SearchController {
private SearchService searchService;
private SearchSession searchSession;
@GetMapping("/search")
public DeferredResult<ModelAndView> getResults() {
DeferredResult<ModelAndView> deferredResult = new DeferredResult<>();
searchService.search("param1", "param2")
.map(results -> {
searchSession.setResults(results);
return results;
)
.subscribeOn(Schedulers.io())
.subscribe(
results -> {
ModelAndView view = new ModelAndView("search");
view.addObject("results", results);
deferredResult.setResult(view);
);
return deferredResult;
}
}
</code></pre>
<p>I tried to define a class which extends RequestContextListener and set parameter inheritable to true when calling RequestContextHolder.setRequestAttributes to allow inheritance between the thread which initially handle the request and the RxJava thread but it didn't work.</p>
<pre><code>public class InheritableRequestContextListener extends RequestContextListener {
private static final String REQUEST_ATTRIBUTES_ATTRIBUTE =
InheritableRequestContextListener.class.getName() + ".REQUEST_ATTRIBUTES";
@Override
public void requestInitialized(ServletRequestEvent requestEvent) {
if (!(requestEvent.getServletRequest() instanceof HttpServletRequest)) {
throw new IllegalArgumentException(
"Request is not an HttpServletRequest: " + requestEvent.getServletRequest());
}
HttpServletRequest request = (HttpServletRequest) requestEvent.getServletRequest();
ServletRequestAttributes attributes = new ServletRequestAttributes(request);
request.setAttribute(REQUEST_ATTRIBUTES_ATTRIBUTE, attributes);
LocaleContextHolder.setLocale(request.getLocale());
RequestContextHolder.setRequestAttributes(attributes, true);
}
}
</code></pre>
<p>I also tried to create a custom RxJava scheduler managed by Spring but it didn't work.</p>
<pre><code>@Bean
public Scheduler scheduler() {
final ThreadFactory threadFactory = new ThreadFactoryBuilder()
.setNameFormat("SearchThread-%d")
.setDaemon(true)
.build();
return Schedulers.from(Executors.newFixedThreadPool(10, threadFactory));
}
</code></pre>
<p>Do you have any idea on how could I access my Spring session scoped bean inside RxJava thread ?</p>

ConnectionResetError when trying to send PUT request
|
<p>I'm trying to upload a file using a PUT REST Api, but I get a <code>ConnectionResetError</code>. I've tried using <code>urllib.request.Request()</code> with <code>urllib.request.urlopen()</code>, as well as <code>requests.put()</code>.</p>
<p>It works correctly when I'm using cURL:</p>
<pre><code>$ curl -X PUT http://localhost:5000/root.bar/test/1.0/jre -H 'Content-Type: application/java-archive' -H 'Content-Name: bfg-1.12.16.jar' -H 'Authorization: Basic cm9vdDphbHBpbmU=' -d @C:/Users/niklas/Desktop/bfg-1.12.16.jar
</code></pre>
<p>The important portion of the code:</p>
<pre><code>headers = {'Content-Type': args.mime, 'Content-Name': args.name}
if args.auth:
headers['Authorization'] = build_basicauth(username, password)
url = args.apiurl.rstrip('/') + '/{}/{}/{}/{}'.format(*parts)
if not urllib.parse.urlparse(url).scheme:
url = 'https://' + url
if args.test:
command = ['curl', '-X', 'PUT', url]
for key, value in headers.items():
command += ['-H', '{}: {}'.format(key, value)]
command += ['-d', '@' + args.file.name]
print('$', ' '.join(map(shlex.quote, command)))
return 0
response = requests.put(url, data=args.file, headers=headers)
print(response)
</code></pre>
<p><strong>What am I missing that cURL is doing?</strong></p>
<p>(PS: I've also tried sending <code>bytes</code> instead of a file-like object using <code>requests.put()</code> by passing <code>data=args.file.read()</code> instead)</p>
<hr>
<p>The full traceback:</p>

having issues calling a method in java
|
<p>a simple question but i litterally can not remember, basically i want to run java methods in an certain order, i did have it working perfectly, but i have had to add something to the start and now it will not run in order </p>
<p>Basically before was this code, </p>
<pre><code>@PostConstruct
public void init() {
//System.out.println(destinationPDF);
//System.out.println(destination);
// Get the username from the login page, this is used to create a folder for each user
System.out.println("called get username");
username = FacesContext.getCurrentInstance().getExternalContext().getRemoteUser();
}
public void File() {
File theFile = new File(destination + username); // will create a sub folder for each user (currently does not work, below hopefully is a solution)
theFile.mkdirs();
System.out.println("Completed File");
}
</code></pre>
<p>it would run and automatically call the next required method, it would call them in this order :</p>
<pre><code>INFO: buttonToUploadText invoked
INFO: called get username
INFO: called handle file
INFO: Completed Creation of folder
INFO: Now in copying of file proccess
INFO: Completed Creation of folder for copy of PDF
INFO: End of copying file creation
INFO: Called CopyFile
INFO: New file created!
INFO: Copying is now happening
</code></pre>
<p>But i have added a new method, that calls variables from a file :</p>
<pre><code>@PostConstruct
public void loadProp() {
System.out.println("Loading properties");
InputStream in = this.getClass().getClassLoader().getResourceAsStream("config.properties"); //points to a properties file, this will load up destinations instead of having to declare them here
try {
configProp.load(in);
System.out.println(configProp.getProperty("destinationPDF"));
System.out.println(configProp.getProperty("destination"));
System.out.println(configProp.getProperty("fileList"));
} catch (IOException e) {
e.printStackTrace();
}
}
</code></pre>
<p>This now must run first when it is triggered in order to declare variables, however now it will now run public void int() once complete instead it skips a lot and runs public void handleFileUpload</p>
<p>so what is the best way of calling public void init() from public void loadProp() {</p>
<p>Edit 2:</p>
<pre><code> private Properties configProp = new Properties();
public void loadProp() {
System.out.println("Loading properties");
InputStream in = this.getClass().getClassLoader().getResourceAsStream("config.properties"); //points to a properties file, this will load up destinations instead of having to declare them here
try {
configProp.load(in);
System.out.println(configProp.getProperty("destinationPDF"));
System.out.println(configProp.getProperty("destination"));
System.out.println(configProp.getProperty("fileList"));
} catch (IOException e) {
e.printStackTrace();
}
}
private String destinationPDF = configProp.getProperty("destinationPDF");
public String destination = configProp.getProperty("destination");
private String username;
//public static String destination = "D:/Documents/NetBeansProjects/printing~subversion/fileupload/uploaded/"; // main location for uploads//TORNADO ONLY //"D:/My Documents/NetBeansProjects/printing~subversion/fileupload/uploaded/"; // USE ON PREDATOR ONLY
public static String NewDestination;
public static String UploadedfileName;
public static String CompletefileName;
//
//Strings for file copy
//
//private String destinationPDF = "D:/Documents/NetBeansProjects/printing~subversion/fileupload/web/resources/pdf/"; //USE ON TORNADO//"D:/My Documents/NetBeansProjects/printing~subversion/fileupload/web/resources/pdf/";//USE ON PREDATOR
private String NewdestinationPDF;
public static String PdfLocationViewable;
//
@PostConstruct
public void init() {
FileUploadController.loadProp();
//System.out.println(destinationPDF);
//System.out.println(destination);
// Get the username from the login page, this is used to create a folder for each user
System.out.println("called get username");
username = FacesContext.getCurrentInstance().getExternalContext().getRemoteUser();
}

stuck at reading credentials from txt file correctly
|
<p>I am stuck at reading credentials from txt file. what am I doing wrong?</p>

Spring form validate : Whitelabel Error Page

<pre><code> @RequestMapping(method = RequestMethod.GET, value = "/add")

<p>I make spring form like above the code. And it works well like above the picture.</p>
<pre><code>@RequestMapping(method = RequestMethod.GET, value = "/{id}/admin/update")
public ModelAndView update(Model model,

<p>Otherwise, above the code does not work well. It's validator works well and it update the contents. But it generate <code>Whitelabel Error Page</code> when validator works.</p>
<p>I don't know why it generate <code>Whitelabel Error Page</code>.</p>

Why in bootstrap 4.1 left aside menu icon to dropdown items is not on valid place?
|
<p>I have a left aside menu with submenus in laravel 5.7 / blade/ Bootstrap 4.1 app and if some element of submenu is opened
I want to keep open parent menu item. I tried to keep it ny current control name as :</p>
<pre><code><?php $manage_storage= ($current_controller_name == 'ClientsController'); ?>
<div class="sidebar-header">
@if(isset($app_name))<h3>{{ $app_name }}</h3>@endif
</div>
<ul class="list-unstyled components">
<li>
<a href="#users_submenu" data-toggle="collapse" aria-expanded="false" class="dropdown-toggle">Manage Users</a>
<ul class="collapse list-unstyled" id="users_submenu">
<li>
<a href="#">Manage Departments</a>
</li>
<li>
<a href="#">Manage Users</a>
</li>
</ul>
</li>
<li>
<a href="#manage_storage_submenu" data-toggle="@if($manage_storage) dropdown @else collapse @endif" aria-expanded="@if($manage_storage) true @else false @endif" class="@if($manage_storage) @else dropdown-toggle @endif">Manage Storage</a>
<ul class="collapse list-unstyled @if($manage_storage) show @endif" id="manage_storage_submenu">
<li class=" @if($current_controller_name == 'ClientsController') active @endif ">
<a href="{{ url('admin/clients') }}">Manage Clients</a>
</li>
<li>
<a href="#">Manage Locations</a>
</li>
<li class=" @if($current_controller_name == 'WarehousesController') active @endif ">
<a href="{{ url('admin/warehouses') }}" >Manage Warehouses</a>
</li>
</ul>
</li>
</code></pre>
<p>So if clients page is opened, then Manage Storage menu must be opened.</p>
<p>But it does not work as I expected:
Please, open :
<a href="http://demo2.nilov-sergey-demo-apps.tk/admin/warehouses/2/edit" rel="nofollow noreferrer">http://demo2.nilov-sergey-demo-apps.tk/admin/warehouses/2/edit</a>
It is under credentials admin@demo.com 111111</p>
<p>look at <a href="http://demo2.nilov-sergey-demo-apps.tk/admin/dashboard" rel="nofollow noreferrer">http://demo2.nilov-sergey-demo-apps.tk/admin/dashboard</a> and <a href="http://demo2.nilov-sergey-demo-apps.tk/admin/clients" rel="nofollow noreferrer">http://demo2.nilov-sergey-demo-apps.tk/admin/clients</a> pages
for the first page (when Manage Storage is not opened) icon to dropdown submenu items is in other place of the page:
on the second page( when Manage Storage is opened ) I do not see the icon to dropdown submenu items.</p>
<p>How to fix it ?</p>
<p><strong>UPDATED BLOCK # 1</strong>
Setting </p>
<pre><code><li style="position: relative;">
</code></pre>
<p>Icon is on its proper place, but “Manage Storage” is not clickable.
I tried and did not find any difference with “Manage Users” menu item, which has no php code in itself and works ok.
What is wrong?</p>
<p><strong>UPDATED BLOCK # 2:</strong>
I checked my html generated code under <a href="https://validator.w3.org" rel="nofollow noreferrer">https://validator.w3.org</a>
and got error :</p>
<pre><code>Error: Bad value false for attribute aria-expanded on element a.
From line 96, column 4; to line 96, column 112
ive;">↩ <a href="#manage_storage_submenu" data-toggle=" collapse " aria-expanded=" false " class=" dropdown-toggle "><span
</code></pre>
<p>I think that the error is called by space in aria-expanded= definition, as I had blade source :</p>
<pre><code> <a href="#manage_storage_submenu" data-toggle="@if($manage_storage) dropdown @else collapse @endif" aria-expanded="@if($manage_storage) true @else false @endif" class="@if(!$manage_storage) dropdown-toggle @endif"><span style="text-decoration: underline">Manage Storage</span></a>
</code></pre>
<p>But if I remove space in aria-expanded= definition I got blade syntax error. Could it raise my problems? Which is the valid way here?</p>
<p>Thanks!</p>

How can I limit interstitial ad opening?
|
<p>I am a newbie in the developing section, recently I'm trying to edit the source code of the web view application. But the problem is every time of "backpress" interstitial ad appears. Which is huge disturbing. Tried to change back press code but after doing that ads totally diseapred. Now I'm confused that how can I solve this problem. Because if a web view app show ads every back press, probably google will not approve it on play store even if accepts then people will not use this app.</p>
<p>I've tried to limit but cannot understand, please help me.
If this is possible the ad shows only one time of back press or at least a limited backpress.</p>
<p>Thanks in advance <3 <3</p>

Emit variable not passing array from child to parent?
|
<p>I am trying to pass an array of tags from the child component to the parent component using emit. The emit is registering and firing the method in the parent component, but when I log the argument that I passed via emit it returns undefined. I am not sure what I am doing wrong because I have passed objects via emit before. </p>
<p>I have tried trying to convert the array to an object, passing it as the this value of the same name without storing it as a variable within the method itself. </p>

RecyclerView showing actually deleted items
|
<h3>Problem</h3>
<p>I am writing an android application that has to handle a variable amount of elements in a RecyclerView. When I add an element, some data gets saved into a configuration file along with an UUID.</p>
<p>Either when the application starts or when the element gets created or removed by the user during runtime, the RecyclerView gets updated and shows all currently existing elements.</p>
<p>Each of these elements has a button to remove it and its additional data from the configuration. When I press this button, the elements data successfully gets removed from the configuration and it turns invisible leading the RecyclerView only to show the remaining elements.</p>
<p>However, when I try to insert a new element, it doesn't get shown but rather the element that has been removed previously during this session.</p>
<h3>Tries</h3>
<p>I have been looking for a solution for a while now.
First of all, I startet reading the documentation over and over again, thinking that I missed something. I also viewed some online examples on how to remove an item from a RecyclerView properly but I can't get it working.</p>
<h3>Code</h3>
<pre><code>package com.rappee.protectiveparking.ui
import android.support.v7.widget.RecyclerView
import android.view.LayoutInflater
import android.view.ViewGroup
import com.rappee.protectiveparking.R
import com.rappee.protectiveparking.core.Resources
import java.util.*
class ScrollerAdapter : RecyclerView.Adapter< ConsoleViewHolder >() ,
DragItemTouchHelperAdapter {
private var stockpile: Queue< String > = LinkedList< String >()
private var holder: MutableList< ConsoleViewHolder > = ArrayList()
fun push( identification: String ) {
this.stockpile.add( identification )
this.notifyItemInserted( this.itemCount - 1 )
}
fun remove( position: Int ) {
this.holder.removeAt( position )
this.notifyItemRemoved( position )
}
override fun onCreateViewHolder( parent: ViewGroup , type: Int ): ConsoleViewHolder {
val view: ConsoleViewHolder = ConsoleViewHolder( LayoutInflater.from( parent.context ).inflate( R.layout.console , parent , false ) , this.stockpile.poll() )
this.holder.add( view )
return view
}
override fun onBindViewHolder( holder: ConsoleViewHolder , position: Int ) {
return
}
override fun getItemCount(): Int {
return this.holder.size + this.stockpile.size
}
override fun onItemMove( from: Int , to: Int ): Boolean {
Collections.swap( this.holder , to , from )
for ( i in 0 until this.holder.size ) {
Resources.CONFIGURATION.push( "${this.holder.get( i ).identification}.${Resources.KEY_POSITION}" , "$i" )
}
this.notifyItemMoved( from , to )
return true
}
}
</code></pre>
<h3>Behaviour</h3>
<p>When I try to insert a new element, I actually put the UUID into 'stockpile' and call 'notifyItemInserted', so that 'onCreateViewHolder' gets activated. When this happens, I fetch the foremost UUID from 'stockpile' in form of a String to give it to the constructor of 'ConsoleViewHolder' as a parameter.
Only when this method gets called, an actual View gets pushed into the RecyclerView ( not my decision! ).</p>
<p>However, when I insert a new UUID and update the RecyclerView after an item got deleted, this method doesn't get called so that no new View can be shown.
The only thing that changes is that the previously deleted View pops back up.</p>
<p><strong>MY QUESTION: How can I fix this behaviour of my RecyclerView showing deleted items instead of newly pushed ones?</strong></p>

Combine two select statments to fetch data from DB
|
<p>I am little bit confuse about the problem and I dont know how to respolve this.
So the problem is following. I have two <code>Models</code>(<strong>ReportElement, ReportDefinition</strong>) and one <code>ViewModel</code> (<strong>ReportElementDefinitionVM</strong>) </p>
<p><strong>ReportDefinition Model</strong></p>
<pre><code>public partial class IzvjestajDefinicija
{
public IzvjestajDefinicija()

public virtual ICollection<IzvjestajElementi> IzvjestajElementi { get; set; }
public virtual ICollection<IzvjestajiGenerisani> IzvjestajiGenerisani { get; set; }
}
</code></pre>
<p><strong>ReportElement Model</strong></p>
<pre><code>public partial class IzvjestajElementi
{
public int IzvjestajElementiId { get; set; }
public int? IzvjestajDefinicijaId { get; set; }

public string KorisnikUnosa { get; set; }
public string KorisnikAzurirao { get; set; }
public virtual IzvjestajDefinicija IzvjestajDefinicija { get; set; }
}
</code></pre>
<p>And ReportElementDefinitionVM</p>
<pre><code>public class GenerisaniIzvjestajiVM
{
public int IzvjestajiGenerisaniId { get; set; }
public int? IzvjestajDefinicijaId { get; set; }
public int? IzvjestajXsdshemaiId { get; set; }
public string ShemaXSD { get; set; }
public string KratkiNazivDefinicijeI { get; set; }

public string NazivXmlfajla { get; set; }
public string Elementi { get; set; }
public string ElementiVrijednosti { get; set; }
}
</code></pre>
<p>And right now I have one <code>Select</code> statment which take elemnt from <code>ReportDefinition</code> and <code>ReportElementDefinitionVM</code> </p>
<pre><code> public ListaSveVM UcitajIzvjestaj()
{
var listaFromDb = _context.IzvjestajDefinicija.Where(x => x.Status == 1).ToList().OrderByDescending(x => x.IzvjestajDefinicijaId);
var listaM = new List<GenerisaniIzvjestajiVM>();
var data = _context.IzvjestajDefinicija.Where(x => x.Status == 1).OrderByDescending(x => x.IzvjestajDefinicijaId)
.Select(i => new GenerisaniIzvjestajiVM()

}).ToList();
var lista = "";
lista = JsonConvert.SerializeObject(data, Newtonsoft.Json.Formatting.None);
var listaVM = new ListaSveVM();
listaVM.sve = lista;
return listaVM;
}
</code></pre>
<p>And Right now, I want to take two property from ReportElement which is (Element,ElementValue) to be display in my <code>View</code> and so far I create something like this: </p>
<pre><code> var elementi = _context.IzvjestajElementi.Where(x => x.Status == 1).OrderBy(x => x.IzvjestajDefinicijaId)
.Select(i => new GenerisaniIzvjestajiVM()
{
Elementi = i.Element,
ElementiVrijednosti = i.ElementVrijednosti
}).ToList();
</code></pre>
<p>And when I pass <code>elementi</code> to I get error</p>
<p><code>lista = JsonConvert.SerializeObject(data, Newtonsoft.Json.Formatting.None);</code></p>
<pre><code>Severity Code Description Project File Line Suppression State
Error CS1503 Argument 2: cannot convert from 'System.Collections.Generic.List<IZ.Model.VM.GenerisaniIzvjestajiVM>' to 'Newtonsoft.Json.JsonConverter'
</code></pre>
<p>And I also try to create another ViewModel to combine all data from those two models, but I can not fetch data.
Sorry for long post, but problem is very complicated and I describe problem as better as I can.
Does anyone know how to solve this problem I would be very thankful. </p>
<p><strong>Update</strong></p>
<p><strong>IzvjestajElementi.cs</strong></p>
<pre><code>using System;

</code></pre>
<p>I get error</p>
<p>Error CS1503 Argument 2: cannot convert from 'System.Collections.Generic.List' to 'Newtonsoft.Json.Formatting'</p>
<p>I need something like this </p>

How to merge REST call results in Angular app more efficiently
|
<p>I have an Angular SPA running on a SharePoint 2013 page. In the code, I'm using $q to pull data from 10 different SharePoint lists using REST and then merging them into one JSON object for use in a grid. The code runs and outputs the intended merged data but it's leaky and crashes the browser after a while. </p>
<p>Here's the code in the service:</p>
<pre><code>factory.getGridInfo = function() {
var deferred = $q.defer();
var list_1a = CRUDFactory.getListItems("ListA", "column1,column2,column3");
var list_1b = CRUDFactory.getListItems("ListB", "column1,column2,column3");
var list_2a = CRUDFactory.getListItems("ListC", "column4");
var list_2b = CRUDFactory.getListItems("ListD", "column4");
var list_3a = CRUDFactory.getListItems("ListE", "column5");
var list_3b = CRUDFactory.getListItems("ListF", "column5");
var list_4a = CRUDFactory.getListItems("ListG", "column6");
var list_4b = CRUDFactory.getListItems("ListH", "column6");
var list_5a = CRUDFactory.getListItems("ListI", "column7");
var list_5b = CRUDFactory.getListItems("ListJ", "column7");
$q.all([list_1a, list_1b, list_2a, list_2b, list_3a, list_3b, list_4a, list_4b, list_5a, list_5b])
.then(function(results){
var results_1a = results[0].data.d.results;
var results_1b = results[1].data.d.results;
var results_2a = results[2].data.d.results;
var results_2b = results[3].data.d.results;
var results_3a = results[4].data.d.results;
var results_3b = results[5].data.d.results;
var results_4a = results[6].data.d.results;
var results_4b = results[7].data.d.results;
var results_5a = results[8].data.d.results;
var results_5b = results[9].data.d.results;
var combined_1 = results_1a.concat(results_1b);
var combined_2 = results_2a.concat(results_2b);
var combined_3 = results_3a.concat(results_3b);
var combined_4 = results_4a.concat(results_4b);
var combined_5 = results_5a.concat(results_5b);
for(var i = 0; i < combined_1.length; i++){
var currObj = combined_1[i];
currObj["column4"] = combined_2[i].column4;
currObj["column5"] = combined_3[i].column5;
currObj["column6"] = combined_4[i].column6;
currObj["column7"] = combined_5[i].column7;
factory.newObjectArray[i] = currObj;
}
deferred.resolve(factory.newObjectArray);
},
function (error) {
deferred.reject(error);
});
return deferred.promise;
};
</code></pre>
<p>Here's the REST call in CRUDFactory:</p>
<pre><code>factory.getListItems = function (listName, columns){
var webUrl = _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/getByTitle('"+listName+"')/items?$select="+columns+"&$top=5000";
var options = {
headers: { "Accept": "application/json; odata=verbose" },
method: 'GET',
url: webUrl
};
return $http(options);
};
</code></pre>
<p>And then here's the controller bit:</p>
<pre><code>$scope.refreshGridData = function(){
$scope.hideLoadingGif = false;
$scope.GridData = "";
GlobalFactory.getGridInfo()
.then(function(){
$scope.GridData = GlobalFactory.newObjectArray;
$scope.hideLoadingGif = true;
});
};
</code></pre>
<p><strong>UPDATE 1:</strong> Per request, Here's the HTML (just a simple div that we're using angular-ui-grid on)</p>
<pre><code><div ui-grid="GridOptions" class="grid" ui-grid-selection ui-grid-exporter ui-grid-save-state></div>
</code></pre>
<p>This code starts by declaring some get calls and then uses $q.all to iterate over the calls and get the data. It then stores the results and merges them down to 5 total arrays. Then, because my list structure is proper and static, I'm able to iterate over one of the merged arrays and pull data from the other arrays into one master array that I'm assigning to factory.newObjectArray, which I'm declaring as a global in my service and using as my grid data source.</p>
<p>The code runs and doesn't kick any errors up but the issue is with (I believe) the "getGridInfo" function. If I don't comment out any of the REST calls, the browser uses 45 MB of data that doesn't get picked up by GC which is then compounded for each click until the session is ended or crashes. If I comment out all the calls but one, my page only uses 18.4 MB of memory, which is high but I can live with it. </p>
<p>So what's the deal? Do I need to destroy something somewhere? If so, what and how? Or does this relate back to the REST function I'm using?</p>
<p><strong>UPDATE 2:</strong> The return result that the grid is using (the factory.newObjectArray) contains a total of 5,450 items and each item has about 80 properties after the merge. The code above is simplified and shows the pulling of a couple columns per list, but in actuality, I'm pulling 5-10 columns per list.</p>

outer join two anonymous types and reference a single property in the join query?
|
<p>Given:</p>
<pre><code>var memberships = context.Memberships.OrderBy("it.CreateDate").ToList();
var monthlyCounts = from m in memberships
where m.CreateDate >= today.AddDays(-365) && m.CreateDate <= today
group m by m.CreateDate.Month
into g
select new
{
MemberCount = g.Count(m => m.UserId != null),
MembershipDate = g.Key,
};
</code></pre>
<p>I'm trying to join that with a list of months:</p>
<pre><code> var months = Enumerable.Range(0, (d1.Year - d0.Year) * 12 + (d1.Month - d0.Month + 1))
.Select(m => new DateTime(d0.Year, d0.Month, 1).AddMonths(m).Month);
</code></pre>
<p>This is what I came up with:</p>
<pre><code>var cumlativeCounts = from d in months
join m in monthlyCounts on d equals m.MembershipDate into ms
from m in ms.DefaultIfEmpty()
select new
{
Month = d,
Count = m.MemberCount
};
</code></pre>
<p>Problem is I get an 'Object Reference not Set to an Instance of an Object' Exception, presumably on m.MemberCount</p>
<p>When I just use Count = m then I get all the properties from the monthlyCounts anonymous type, which is not exactly what I want. </p>
<p>Is there another way to outer join two anonymous types and reference a single property in the join query? </p>
<p>Thanks in advance.</p>

<p>Can you find out where I made mistake in class style script?</p>
<p>And why the GUI layout of these two codes look so differently? I tried to debug in class style script but failed.(the buttons location is different)</p>

<p>But I'm getting duplicates in the 'projects' array (if I'm having the same project with a different product, it will show twice instead of having a single project with 2 products in the products array</p>
<p>Will appreciate your help with finding the right pipeline stages to manipulate my results are expected</p>

Unclickable context menu inside content editable
|
<p>I have a little issue with my context menu inside a content editable. I think it's a style issue but i can't figure out what it's causing it. Here is the thing, my context menu is showing where he is suposed to, with the value he is suposed to have. But it seems like it is only a block for him and not a list of P element Inside my DIV element.</p>
<p><a href="https://i.stack.imgur.com/XoJf2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/XoJf2.png" alt="enter image description here"></a></p>
<p>As you can see we can't click on the element Inside the context Menu.</p>
<p>My CSS : </p>
<pre><code>.ctxmenu
{
display: block;
position: absolute;
height: auto;
padding: 0px;
margin: 0;
margin-left: 0.5em;
margin-top: 0.5em;
border: 1px solid black;
background: #F8F8F8;
z-index: 11;
overflow: visible;
}
.ctxline
{
display: block;
margin: 0px;
padding: 0px 0px 0px 3px;
border: 1px solid #F8F8F8;
overflow: visible;
}
.ctxline:hover
{
border: 1px solid #BBB;
background-color: #F0F0F0;
background-repeat: repeat-x;
}
</code></pre>
<p>The content editable CSS :</p>
<pre><code>.rootClass

<p>the HTML : </p>

<p>Or if you know any properties that might end up doing this, my cowerker may have hide some CSS on other place (they did not use a CSS file to put all style inside ...).</p>

AltBeacon ignores pdu type of my beacon packages
|
<p>I'm using AltBeacon library to work with my beacons (provided by Shenzhen Minew Technologies Co., Ltd.).
I use following</p>
<pre><code>beaconManager.getBeaconParsers().add(new BeaconParser().
setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));
</code></pre>
<p>to set layout. In my logcat I see RSSI values coming from my beacons like:</p>
<pre><code>06-21 01:50:27.091 13496-13507/com.example.tkobilov.minewtestapp D/BluetoothAdapter﹕ onScanResult() - Device=CD:A6:29:2F:08:26 RSSI=-73

06-21 01:50:27.508 13496-13582/com.example.tkobilov.minewtestapp D/BluetoothAdapter﹕ onScanResult() - Device=D3:EB:21:87:9D:7E RSSI=-59
</code></pre>
<p>However in</p>
<pre><code>protected Beacon fromScanData(byte[] bytesToProcess, int rssi, BluetoothDevice device, Beacon beacon) {
BleAdvertisement advert = new BleAdvertisement(bytesToProcess);
Pdu pduToParse = null;
for (Pdu pdu: advert.getPdus()) {
if (pdu.getType() == Pdu.GATT_SERVICE_UUID_PDU_TYPE ||
pdu.getType() == Pdu.MANUFACTURER_DATA_PDU_TYPE) {
pduToParse = pdu;
if (LogManager.isVerboseLoggingEnabled()) {
LogManager.d(TAG, "Processing pdu type %02X: %s with startIndex: %d, endIndex: %d", pdu.getType(), bytesToHex(bytesToProcess), pdu.getStartIndex(), pdu.getEndIndex());
}
break;
}
else {
if (LogManager.isVerboseLoggingEnabled()) {
LogManager.d(TAG, "Ignoring pdu type %02X", pdu.getType());
}
}
</code></pre>
<p>I every time come to "Ignoring pdu type...".
I checked bytesToProcess array. Every time it has just 1st and 2nd nonzero values. Other values are zero. BeaconCFG application recommended by Minew founds these beacons without any problems but I need AltBeacon for my project. What might be the reason of this? </p>

Im trying to create a space dodge game and I'm having a few issues
|
<p>Basically I'm trying to have it so that when the ship touches the meteor it plays an explode animation. I'm using colour detection for this as when i used <code>player.colliderect(name)</code> it was really inaccurate and began the animation when it was far away from the asteroid. So im using colour detection now in hopes that it'll work better and be more accurate. This is the code i tried making for that (i know its commented out):</p>
<pre class="lang-py prettyprint-override"><code># pixel_colour = screen.get_at(player.pos) #collision with colour makes ship explode
# red = pixel_colour[0]
# blue = pixel_colour[1]
# green = pixel_colour[2]
# if red and green and blue != 0:
# print("oof")
# gameover()
</code></pre>
<p>Here is the <code>gameover()</code> subroutine:</p>
<pre class="lang-py prettyprint-override"><code>def gameover(): #ship exploding animation
player.image = 'explode.png'
clock.schedule_unique(game_over, 0.3)
def game_over():
player.image = 'explode1.png'
clock.schedule_unique(overgame, 0.3)
def overgame():
player.image = 'explode2.png'
vel = 0 #stop the ship from moving (doesnt work)
</code></pre>
<p>it says "screen" doesn't have the attribute "get_at" so i tried it with "surface" instead of "screen" and it said that "surface is not defined" I really dont know what to do with it...
Also i tried to make the player stop being able to move when they get a game over (as seen inside the second bit of code when i make <code>vel</code> 0 it says "vel is not defined" and "vel is used before assignment") Heres my full code so you know what im doing :D</p>
<pre class="lang-py prettyprint-override"><code>import pgzrun
import pygame
import random
WIDTH = 850
HEIGHT = 425
#sprites
player = Actor('ship.png')
player.pos = 100, 56

</code></pre>
<p>also i have experimented with wrapping (as you can see on the line that goes <code>if player.left > WIDTH: player.right = 0</code>) i would like this to be the same with the other sides as well. But im trying to work this out at the moment so if you don't talk about this then its fine because im sure i can figure it out haha :D</p>
<p>so the code is working perfectly fine but i would like to get these things working as its the core of the game. Thanks if you can help :D</p>

REST api returning json but configured as XML?
|
<p>I'm trying to get an XML response from my server but for some reason it still returns JSON. Maybe I'm misunderstanding what setAccept and setContentType are? At the moment I'm thinking that the get request is in XML but the client is only accepting / expecting json? </p>
<p>I've tried setting headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON)); to XML instead but it ends up giving me an error "Cannot find representation". I also took out JSON from the consumes = "" but it stopped working when i did that too.</p>

Run-time error '1004' in a If else statement program
|
<p>I am trying to use two cells to determine which value to return back. The goal is to read in cell Z3 to determine which height to use, then cell AA3 to determine which Class to use based off the value the height provided. Once the class is found i would like it to print to cell AB3 then repeat for the next row and so on.</p>
<p>I am currently getting a Run Time error 1004. I am not sure what is causing this I looked it up and said it could be cause by an empty variable but I am not seeing it. Any help would be great thanks!</p>
<p>This is for a small project at work I am not great at VBA and just wanted to try and make a task easier and not take as long. </p>

Spring: JUnit tests with session scope: Unsatisfied dependency expressed through field 'sessionTestBean'

<p>Thread 2 : Load all Requirement</p>
<p>and run parallel but i think is not supported parallel request. Because when i fetch requirement it takes <strong>40 second (for 30 requirements)</strong> but fetch both parallel taking <strong>1 minute 15 second</strong> for only requirements .</p>

Calculate Dice Roll from Text Field
|
<p>QUESTION:
How can I read the string "d6+2-d4" so that each d# will randomly generate a number within the parameter of the dice roll?</p>
<p>CLARIFIER:
I want to read a string and have it so when a d# appears, it will randomly generate a number such as to simulate a dice roll. Then, add up all the rolls and numbers to get a total. Much like how Roll20 does with their /roll command for an example. <code>If !clarifying {lstThen.add("look at the Roll20 and play with the /roll command to understand it")} else if !understandStill {lstThen.add("I do not know what to say, someone else could try explaining it better...")}</code></p>
<p>Info:
I was making a Java program for Dungeons and Dragons, only to find that I have come across a problem in figuring out how to calculate the user input: I do not know how to evaluate a string such as this.</p>
<p>I theorize that I may need Java's <code>eval</code> at the end. I do know what I want to happen/have a theory on how to execute (this is more so <strong>PseudoCode</strong> than Java):</p>
<pre><code>Random rand = new Random();
int i = 0;
String toEval;
String char;
String roll = txtField.getText();
while (i<roll.length) {
check if character at i position is a d, then highlight the numbers
after d until it comes to a special character/!aNumber
// so if d was found before 100, it will then highlight 100 and stop
// if the character is a symbol or the end of the string
if d appears {
char = rand.nextInt(#);
i + #'s of places;
// so when i++ occurs, it will move past whatever d# was in case
// d# was something like d100, d12, or d5291
} else {
char = roll.length[i];
}
toEval = toEval + char;
i++;
}
perform evaluation method on toEval to get a resulting number
list.add(roll + " = " + evaluated toEval);
</code></pre>
<p>EDIT:
With weston's help, I have honed in on what is likely needed, using a splitter with an array, it can detect certain symbols and add it into a list. However, it is my fault for not clarifying on what else was needed. The pseudocode above doesn't helpfully so this is what else I need to figure out.</p>
<pre><code>roll.split("(+-/*^)");
</code></pre>
<p>As this part is what is also tripping me up. Should I make splits where there are numbers too? So an equation like:</p>
<pre><code>String[] numbers = roll.split("(+-/*^)");
String[] symbols = roll.split("1234567890d")
// Rough idea for long way
loop statement {
loop to check for parentheses {
set operation to be done first
}
if symbol {
loop for symbol check {
perform operations
}}} // ending this since it looks like a bad way to do it...
// Better idea, originally thought up today (5/11/15)
int val[];
int re = 1;
loop {
if (list[i].containsIgnoreCase(d)) {
val[]=list[i].splitIgnoreCase("d");
list[i] = 0;
while (re <= val[0]) {
list[i] = list[i] + (rand.nextInt(val[1]) + 1);
re++;
}
}
}
// then create a string out of list[]/numbers[] and put together with
// symbols[] and use Java's evaluator for the String
</code></pre>
<p>wenton had it, it just seemed like it wasn't doing it for me (until I realised I wasn't specific on what I wanted) so basically to update, the string I want evaluated is (I know it's a little unorthodox, but it's to make a point; I also hope this clarifies even further of what is needed to make it work):</p>
<p><strong>(3d12^d2-2)+d4(2*d4/d2)</strong></p>
<p>From reading this, you may see the spots that I do not know how to perform very well... But that is why I am asking all you lovely, smart programmers out there! I hope I asked this clearly enough and thank you for your time :3</p>

12 month moving average from Java array
|
<p>i have tried to use this code to calculate 12 month moving average. i have the data below the third column is the value i would like to calculate the average on .<br>
the problem with this code is that it outputs the moving average as the values converted to double</p>
<pre><code>//a is an object of the larger class
//x is the collection of values to be averaged
public int bars = 1;
double[] movavg = new double[x.length - bars]; //
int k = 0;
try {
for (int i = a.bars - 1; i < a.x.length - 1; i++) // for each bar
{
a.movavg[a.k] = 0.0;
for (int j = 0; j < a.bars; j++) // sum over 'bars' previous input values
{
a.movavg[a.k] += a.x[i - j];
}
double k = a.movavg[a.k++] /= a.bars; // divide by number of bars

<p>Not thing happens! The file I want to read doesn't appear. The only thing appears just a 'true' response.
Look like my XXE payload isn't working. I have try a lot but it still doesn't work, nothing happens, just only that simple response.
Is there any hacker know how to exploit it, help me, please, I will thank you so much!

API Gateway error (ValidationException: ExpressionAttributeValues must not be empty) when trying to update DynamoDB entry
|
<p>I am new to AWS and am trying to set up the back end for my buddy's website. I am able to 'get' entries from my database (called 'isThrowingTable') but am unable to 'put' updates into it. I run a Request Body as seen in the picture/code below and I get a response body (error) as seen in the pic/code (see the lambda function line 28 to see how that response is created, I added stuff to debug it)</p>

<p>As you can see in the error message, params.Key and params.ExpressionAttributeValues are not set and I'm not sure why. In the print out of event.body you can see dataName (the id of the item in the database) and updatedInfo are present but trying to grab it results in 'undefined'. I am hoping for a fix and also to learn why this is happening.</p>

HtmlUnit form submit since button does not have a direct hyperlink
|
<p>I have a button on a page but there is no hyperlink in the button. So I need to submit the form to go to the next page.</p>
<p>HtmlUnit is not waiting till the next page loads. So the <code>nextPage</code> variable is having the current page instead of the next page (intermittently it works if page loads quick enough though). How to resolve this?</p>
<p>Html Page:</p>
<pre><code> <form action="/webapp/NewPage.jsp" id="idForm01" accept-charset="UNKNOWN" onsubmit="return false;"
name="frmNewPageForm" method="post" enctype="application/x-www-form-urlencoded">
<input name="attribute1" type="HIDDEN" value="1">
<input id="attribute2" value="EDIT_ATTRIBUTE2" name="functionalAttribute" type="hidden">
</form>
<table id="idTablePageDetails" class="formTable">
<tbody>
<tr class="formHeaderRow">
<td colspan="4" nowrap="">
Page Details
<a onclick="onClick_newPageButton();return false;" id="newPageButton" title="New Page" href="#" class="smallButton">

if ( document.frmNewPageForm.onsubmit != null ) { document.frmNewPageForm.onsubmit(); }document.frmNewPageForm.submit(); }}
// -->
</script>
</table>
</code></pre>
<p>Code I am using to get the next page:</p>
<pre><code>HtmlPage nextPage = (HtmlPage) page.executeJavaScript("document.frmNewPageForm.onsubmit()").getNewPage(); // from onsubmit

Update one Pmw control using value from another within the same class
|
<p>I am writing a Pmw (<a href="http://pmw.sourceforge.net" rel="nofollow">http://pmw.sourceforge.net</a>) plugin for PyMOL (<a href="http://sourceforge.net/projects/pymol/" rel="nofollow">http://sourceforge.net/projects/pymol/</a>), but I just cannot update the value of a <code>Pmw.ComboBox</code> using changes made to a <code>Pmw.RadioSelect</code> control.</p>
<p>The error I keep getting is:</p>
<pre><code> File "/Users/x/.pymol/plugins/mymixer.py", line 82, in sdqRadioChanged
self.scheme_listing._list.setlist(scList)
<type 'exceptions.AttributeError'>: MyMixer instance has no attribute 'scheme_listing'
</code></pre>
<p>This appears to be a mistake in scope, but I have no idea how to re-architect the entire plugin to be able to access the <code>scheme_listing</code> attribute of a <code>MyMixer</code> instance. Similar examples for python/Pmw/tkinter, on the web, appear to work fine (or so it appears to me with my limited understanding of python GUI programming).</p>
<p>Attached below is a MWE that runs (and fails) from within PyMOL (shows up in the menu under Plugins > MyMixer). Note: If you run this on OSX, make sure you are running PyMOLX11Hybrid.app</p>

<p>No this thread suggest to replace the <code>annotationProcessor</code> in my <code>gradle.build</code> with <code>kapt</code>.
This seemed to do the trick, but then I get another error during comiling for which I've already openend a question <a href="https://stackoverflow.com/questions/72434420/using-kotlin-ubyte-for-room-entity-not-working">Using kotlin.UByte for Room Entity not working</a></p>

componentWillUnmount works after switching to another page
|
<p>I have two pages and two components LibraryPageFilters.tsx (url: /courses) and UserVideoCreatePage.tsx (url: /ugc/courses/${course.id}).
In component LibraryPageFilters.tsx</p>
<pre><code>useEffect(() => {
console.log(course.id)
if (course.id) {
console.log(544)
dispatch(push(`/ugc/courses/${course.id}`));
}
}, [course]);
</code></pre>
<p>i have a check that if course.id present in the store, then we make a redirect.
In component UserVideoCreatePage.tsx</p>
<pre><code> useEffect(() => {
return () => {
console.log(333344444)
dispatch(courseDelete());
};
}, []);
</code></pre>
<p>i am deleting a course from the store when componentUnmount.</p>
<p><a href="https://i.stack.imgur.com/H4e5A.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/H4e5A.png" alt="enter image description here" /></a></p>
<p>why does unmount happen after a redirect? as a result, I am redirected back. Because the course is not removed from the store at the moment of unmount, and the check (if (course.id)) shows that the course is in the store and a redirect occurs back (dispatch(push(<code>/ugc/courses/${course.id}</code>)))</p>

react-select doesn't re-render when updating the state

<p>I'm trying to set a multi filter that includes react-select.
it works properly only when another part of the filter is activated (typing in the input for example).</p>
<p>Tried console.logging inside the service, nothing happens when adding to the multi select, but only when i use the other types of filters.</p>
<p>Filter component :</p>
<pre><code>import React from 'react';
import Select from 'react-select'
const options =[

CABasicAnimation only works with layers created in the same method
|
<p>I need to animate different CATextLayers depending on some conditions. This is why I wrote a method that accepts the layer and animates it. Here it is:</p>
<pre><code>- (void) animateText:(CATextLayer*) text withColor: (CGColorRef) color andDuration: (NSTimeInterval) duration
{
CABasicAnimation *colorAnimation = [CABasicAnimation
animationWithKeyPath:@"foregroundColor"];
colorAnimation.duration = duration;
colorAnimation.fillMode = kCAFillModeForwards;
colorAnimation.removedOnCompletion = NO;
colorAnimation.fromValue = (id)[UIColor redColor].CGColor;
colorAnimation.toValue = (id)[UIColor blackColor].CGColor;
colorAnimation.timingFunction = [CAMediaTimingFunction
functionWithName:kCAMediaTimingFunctionLinear];
[text addAnimation:colorAnimation
forKey:@"colorAnimation"];
</code></pre>
<p>"text" is a CATextLayer created, initialized and added to sublayers in some other method.
The problem is this code does not make the "text" layer animate.</p>
<p>(Please, don't pay attention that the method receives the color. I have temporarily put red and black for testing.)</p>
<p>I started testing. If I create a layer within this method and then try to animate this newly created method, it works ok.
If I copy-paste the code to the method where all layers are created and try to animate one of them - it works fine too.</p>
<p>But I need to animate different layers at different moments, so I see this function as essential.</p>
<p>Please, explain me what I am doing wrong.
Thank you in advance.</p>
<p>UPDATED:
Here's how the layers are created and placed onto UIView</p>
<pre><code>//creating 110 text layers
CGFloat leftPoint = 0;
CGFloat topPoint = 0;
for (int i=0; i<11; ++i)
{
for (int j=0; j<10; ++j)
{
CATextLayer *label = [[CATextLayer alloc] init];
[label setString:[_labels objectAtIndex:j+(i*10)]]; // _labels contains letters to display
[label setFrame:CGRectMake(leftPoint, topPoint, _labelWidth, _labelHeight)]; // _labelWidth and _labelHeight are valid numbers
[label setAlignmentMode:kCAAlignmentCenter];
[label setForegroundColor:_textColor]; // _textColor is a CGColorRef type
[label setFont:(__bridge CFTypeRef)(_font.fontName)]; // font is UIFont type
[label setFontSize:[_font pointSize]];
[_textViews addObject:label]; // saving to internal array variable
[[self layer] addSublayer:label];
leftPoint += _labelWidth;
}
leftPoint = 0;
topPoint += _labelHeight;
}
</code></pre>
<p>If I place a code like this in the same method where I do animating, it works.
And it stops working when I pass the layer in the method like this:</p>
<pre><code>for (int i = 0; i<labelsToHighlight.count; ++i) // labelsToHighlight is an array containing indexes of the CATextLayers which I need to animate
{
NSUInteger index = [[labelsToHighlight objectAtIndex:i] intValue];
[self animateText:[_textViews objectAtIndex:index] withColor: _highlightedTextColor andDuration:_redrawAnimationDuration];
}
</code></pre>

move the x and y of multiple div's on mouse x, y in js
|
<p>my goal is to make a webpage where multiple div's with text etc. within, moves on mouse x and y. It should looks like a parallax effect on mouse x and y. All the parallax plugins that i came across are image based so they don't work with the div's.
I wrote a little js myself but the div's are jumping all over the page, no css can keep em' in place. Maybe someone with more js experience knows how I can solve this. below the code. hope toe hear from you all.</p>
<p>HTML:</p>

<p>Now, I have three columns: "Date", "Cart.Serial" and "Message".

The result data should then be put in another data frame so I can work with it as sample and extract means and other descriptive statistics.</p>
<p>Thanks.</p>

Scala XML processing is skipping a value
|
<p>I am trying to develop a rest api in scala that grabs the xml of a couple of rss feeds and then displays them in json. So far I can display them as text, which is fine, but I can't get the author to show up. I am creating a list of the articles (where Article is a case class), and searching the xml to provide the values for the Article class.</p>
<pre><code><item>

<p>This is an example of the xml I am parsing. Here is the code I am using to parse it:</p>

<p>All of the other values are being processed correctly. Author is the only value that is not showing up. When I call the api to show the articles, this is what I get:</p>

Recursive PHP function writing to external array
|
<p>Two questions here really; why is this happening? And what can be done about it?</p>
<p>Sorry the question's so long but most of it is just <code>print_r</code> output!</p>
<p>Basically, I start with a flat array of tags (<code>$tags</code>) each with an <code>id</code> (array index), <code>name</code> and <code>parent_id</code>. I then recursively iterate over <code>$tags</code> and nest all child tags within their parent. (see below)</p>
<p>It works! (see below for output). But the problem I'm having is that my flat array of tags is being written to from within the function that does the nesting/recursion. (see below)</p>
<p>Flat array of tags:</p>
<pre><code>Array
(
[1] => stdClass Object
(
[name] => instruments
[parent_id] => 0
)
[2] => stdClass Object
(
[name] => strings
[parent_id] => 1
)
[3] => stdClass Object
(
[name] => violin
[parent_id] => 2
)
[4] => stdClass Object
(
[name] => cello
[parent_id] => 2
)
[5] => stdClass Object
(
[name] => woodwind
[parent_id] => 1
)
[6] => stdClass Object
(
[name] => flute
[parent_id] => 5
)
)
</code></pre>
<p>This is the recursively called function to nest the child tags. The problem is inside the <code>if</code>: I assign <code>$tag</code> to <code>$tree[$i]</code> and then add the <code>children</code> property to it. This results in the <code>children</code> property being added to <code>$tag</code>. This is what I want to stop happening.</p>
<pre><code>public function tags_to_tree($tags, $parent_id = 0)
{
$tree = array();
foreach($tags as $i => $tag)
{
// add this tag node and all children (depth-first recursive)
if(intval($parent_id) === intval($tag->parent_id))
{
$tree[$i] = $tag;
$tree[$i]->children = $this->tags_to_tree($tags, $i);
}
}
return $tree;
}
</code></pre>
<p>Nested tags output:</p>
<pre><code>Array
(
[1] => stdClass Object
(
[name] => instruments
[parent_id] => 0
[children] => Array
(
[2] => stdClass Object
(
[name] => strings
[parent_id] => 1
[children] => Array
(
[3] => stdClass Object
(
[name] => violin
[parent_id] => 2
)
[4] => stdClass Object
(
[name] => cello
[parent_id] => 2
)
)
)
[5] => stdClass Object
(
[name] => woodwind
[parent_id] => 1
[children] => Array
(
[6] => stdClass Object
(
[name] => flute
[parent_id] => 5
)
)
)
)
)
)
</code></pre>
<p>What can I do differently when adding the <code>children</code> property to <code>$tree[$i]</code>, or when assigning <code>$tag</code> to <code>$tree[$i]</code> to stop this from happening?</p>
<p>Thanks!</p>

Javascript 2d for loop doesn't iterate through the final value of the outer loop
|
<p>I have a for loop that behaves differently depending on what type of input it has. The logic that changes its behavior can't effect the problem that I am having. Here is my code, then I will explain the problem.</p>
<pre><code>propagateForward(input)
{
for(let i = 0; i < input.length; i++)
{
this.NN[0][i] = input[i];
}
for(let i = 0; i < this.NN.length-1; i++)
{
//The problem occurs between the next two console.logs when the neural network is not
//the Actor agent, but is instead the critic agent. In the console "outside" will print
//and "inside" won't print. Whereas they both should print.
if(i == this.NN.length-2 && !this.isActor) console.log("outside");
for(let j = 0; j < this.NN[i+1].length-1; j++)
{
if(i == this.NN.length-2 && !this.isActor) console.log("inside");
var weightsSum = 0;
for(let r = 0; r < this.NN[i].length; r++)
{
if(r == this.NN[i].length-1 && i != 0)
{
weightsSum += this.NN[i][r];
}
else
{
var NodeVal = this.NN[i][r];
weightsSum += this.weights[i][r][j] * NodeVal;
}
}
if(i == this.NN.length-2)
{
if(!this.isActor) console.log(weightsSum);
this.NN[i+1][j] = weightsSum;
}
else
{
if(this.isActor) this.NN[i+1][j] = tanh(weightsSum);
else
{
this.NN[i+1][j] = ReLU(weightsSum);
}
}
}
}
if(this.isActor)
{
this.NN[this.NN.length-1] = softMax(this.NN[this.NN.length-1]);
}
return this.NN[this.NN.length-1];
}
</code></pre>
<p>It is the propagate forward for a neural network. This question is related to my bug with the for loop and not have anything to do with NN. I need to calculate the last layer of the Critic neural network, but 'i' will not loop to i = 2 which is the last possible idx inside of the inner loop. I have console log on the outside. When I run the program it only detects i = 2 on the outside loop, but can't access it on the inside loop. Thus the console of my program reads:</p>
<pre><code>outside
outside
outside
outside
outside
outside
outside
outside
outside
outside
...
</code></pre>
<p>I want it to say outside and inside.</p>
<p>The only thing in between the two points where I am printing the same information from and getting different results is the declaration of the inner for loop. It works fine when the boolean this.isActor = true (It calculates the actor network just fine). The boolean this.isActor is the only difference between when it works and doesn't work. Neither of the console.log lines where I am testing are being affected by any if statements.</p>
<p>Given that this.NN.length = 4
Question: Why is the inner for loop not able to access i = 2, but the outer for loop can access i = 2?</p>

R Interp functions returns 0s/one value for z variable
|
<p>I am trying to replicate Cesar's solution from here in order to create an interpolation of two CTD transects:
<a href="https://stackoverflow.com/questions/54726853/how-to-interpolate-data-between-sparse-points-to-make-a-contour-plot-in-r-plot">How to interpolate data between sparse points to make a contour plot in R & plotly</a></p>
<p>However, after running the interpolation, the z values of my list objects consist almost exclusively of the value -230 and my resulting plot does not contain any 'color' values and cuts away most of my depths.</p>
<p>My data is as follows:</p>
<p>I have two data frames (df1 & df2) with a subset from df for each transect which look like this</p>
<pre><code>> str(df1)
'data.frame': 120 obs. of 5 variables:
$ Station : int 13 13 13 13 13 13 13 13 13 13 ...
$ x : num 35.5 35.5 35.5 35.5 35.5 ...
$ y : num -39.5 -39.5 -39.5 -39.5 -39.5 ...
$ z : num -758 -758 -595 -595 -506 ...
$ Salinity: num 34.4 34.4 34.5 34.5 34.6 ...
</code></pre>
<p>When running the interpolation as suggested by Cesar like this</p>
<pre><code>z1 <- interp(df1$x, df1$y, df1$z, extrap = TRUE, duplicate = "mean") #interp z layer 1 with spline interp
ifelse(anyNA(z1$z) == TRUE, z1$z[is.na(z1$z)] <- mean(z1$z, na.rm = TRUE), NA) #fill na cells with mean value
</code></pre>
<p>and the interpolation of my Salinity 'color' like this</p>
<pre><code>c1 <- interp(df1$x, df1$y, df1$Salinity, extrap = F, linear = F, duplicate = "mean") #interp co2 layer 1 with spline interp
ifelse(anyNA(c1$z) == TRUE, c1$z[is.na(c1$z)] <- mean(c1$z, na.rm = TRUE), NA) #fill na cells with mean value
</code></pre>
<p>my resulting z1$z looks like this (only around -230 value)</p>
<pre><code>z1$z
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [,11] [,12] [,13] [,14]
[1,] -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318
[2,] -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318
[3,] -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318 -230.7318
</code></pre>
<p>and the resulting c1$z like this (only 0s)</p>
<pre><code>c1$z
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [,11] [,12] [,13] [,14] [,15] [,16] [,17] [,18] [,19] [,20] [,21] [,22] [,23] [,24] [,25] [,26]
[1,] 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

[3,] 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
</code></pre>
<p>My resulting plot (same code as Cesar from link above) then looks like this without any Salinity data and everything clustered around -230 depth:
<a href="https://i.stack.imgur.com/FvdBj.png" rel="nofollow noreferrer">Plot_ly interpolated plot</a></p>
<p>Any help to work out where I have gone wrong would be appreciated. I hope I added enough detail as I am completely new to stackoverflow. Thanks in advance!</p>

Ajax call twice cause duplicate message

<p>I am developing an app using q-municate as base. As given in readme document I copied credentials (App ID, Authorization key, Authorization secret) into my Q-municate project code in Consts.java</p>
<p>I refracted the package name from <code>com.quickblox.qmunicate</code> to <code>com.quickblox.TestingApp</code>
I also changed the package name in AndroidManifest file except <code><uses-permission android:name="com.quickblox.qmunicate.permission.C2D_MESSAGE" /></code> , <code><category android:name="com.quickblox.qmunicate" /></code> </p>

<p>I have to close application and reopen to go to Login page. And problem continues.</p>
<p>What is going wrong?
Any one who developed app using qmunicate and published on google play store please tell what is wrong and what else need to be changed.</p>
<p>Can any one tell before starting modification of qmunicate app, apart from App ID, Authorization key, Authorization secret what else need to be changed?</p>

TypeError: cannot read property of length undefined? - React Carousel
|
<p>Following this tutorial <a href="https://www.youtube.com/watch?v=l1MYfu5YWHc&list=PLVwSdwIkTF50m5Fnd-_vSIrT8mvtfeZxe&index=8" rel="nofollow noreferrer">here</a> exactly because I want to use this carousel on my website.</p>
<p>However I get the error "TypeError: cannot read property of undefined", even though the code is exactly same as tutorial and the tutorial instructor never encounters this error.</p>
<ol>
<li>How do I solve this?</li>
<li>Why do I get this error and the tutorial instructor did not? finding it hard to understand how this happens - the video is only from December 2020</li>
</ol>
<p>Thanks in advance.</p>
<p>Code below:</p>
<pre><code>import React, {useState} from 'react';
import styled from 'styled-components'
import { CarouselData } from '../Data/CarouselData';
import {FaArrowAltCircleRight, FaArrowAltCircleLeft} from 'react-icons/fa';
export const Carousel = ({slides}) => {
const [current, setCurrent] = useState(0);
const length = slides.length;
const nextSlide = () => {
setCurrent(current === length -1 ? 0 : current + 1)
}
const prevSlide = () => {
setCurrent(current === length -1 ? 0 : current + 1);
}
console.log(current);
if (!Array.isArray(slides) || slides.length <= 0){
return null;
}
return (

</code></pre>
<p>I'm using Rails 5.2.5 with ruby 2.3.3 for now.
The error stacktrace isn't telling me anything significant at least nothing that I can determine.</p>
<p>Could I kindly get some pointers as to where can a good place to look be?</p>
<p>Edit: I linked to a post that has an answer to this. Basically if this error happens a good way is to look at the gems to see if there is a specific gem that needs to be upgraded.</p>

"Http 401 Unauthorized" when login through webdriver running browser
|
<p>In the concern website, (<a href="https://zoom.us/signin" rel="nofollow noreferrer">https://zoom.us/signin</a>) when I login in manually through browser, opened with geckodriver webdriver :</p>
<pre><code>browser = webdriver.Firefox() #(Just an example, real code at the end of the answer)
</code></pre>
<p>It first prompts for captcha (which isn't asked for when login through normal browser on same website). Please note that I entered the link manually too. Then, after solving the captcha, it gives me the following error :</p>
<pre><code>error: Http 401 Unauthorized
</code></pre>
<p>And I couldn't login at all, even though I did everything manually, which points out that it is somehow detecting that I'm using webdrive (please note that I'm NOT using headless Firefox).</p>
<p>Now, regarding my findings:</p>
<p>I used inspect element and tried to find what triggers when I click the sign in button.</p>
<p>and, functions from only two files are trigger :</p>
<p><code>login.min.js</code>, and <code>all.min.js</code></p>
<p>I fetched the login.min.js and arranged it in readable form, here it is <a href="https://pastebin.com/SMFt1stC" rel="nofollow noreferrer">https://pastebin.com/SMFt1stC</a></p>
<p>all.min.js is mix of common library, here's the link:
<a href="https://st1.zoom.us/static/5.1.1662/js/all.min.js" rel="nofollow noreferrer">https://st1.zoom.us/static/5.1.1662/js/all.min.js</a></p>
<p>One of the function on <code>login.min.js</code> that gets triggered on clicking sign in is this :</p>
<pre><code>var c = $("#login-form");
.....
.....
l.on("click", function() {
c.find("span.help-block").remove();
c.find("div.has-error").removeClass("has-error");
var t = c.valid();
if (!t) {
c.find("div.has-error input").length && c.find("div.has-error input").eq(0).trigger("focus");
return
}
if (signinNeedCaptcha && newCaptcha.isReCaptcha) {
l.disableBtn();
window.setTimeout(function() { l.enableBtn() }, 3000);

<p>From here, I can clearly see what gets trigger after I click sign in.</p>
<p>I entered it in console manually, that did a HTTP POST request, and it returned with same "Http 401 Unauthorized" error, which made me think what exactly is making it fail.</p>
<p>In short, I want to know how exactly the site finds out that I'm using webdrive, so that I can mitigate it.</p>
<p>To find this out, will I have to read every single JavaScript in the webpage myself to actually figure it out, or am I missing something obvious, or it isn't possible to figure out how they might be detecting browser as the code that might be doing it is in the backend? I'm new to web development so can't really figure that out.</p>
<p>This is how I'm starting the webdriver through Python Selenium:

Trying to take EmployeeID & EName from dropdown to be used in a query to display table

Adding data to table on registration

Inject / Navigate RibbonTabItems depending on selected / loaded module
|
<p>I have got following problem:</p>
<p>There is a Ribbon-region in the Shell, let´s call it the "ShellRibbonRegion". There is also a task button region "ShellTaskButtonRegion" (<a href="http://www.codeproject.com/Articles/165370/Creating-View-Switching-Applications-with-Prism-4" rel="nofollow">similar to Creating View-Switching Applications with Prism 4</a>).</p>
<p>There are e.g. three modules. Each module has a different number of RibbonTabItems. Module 1 has one RibbonTabItem, module 2 four and module 3 one.</p>
<p>The goal is now to add the RibbonTabItems to the "ShellRibbonRegion" after the "TaskButton" of a module is clicked. I already have written a custom RegionAdapter, but the problem is either only one RibbonTabItem (SingleActiveRegion) is shown or all (AllActiveRegion) RibbonTabItems from all modules.</p>

<p>The desired behaviour is following:</p>

Creating javascript objects using jQuery's each() method
|
<p>Im curious about what might be a larger question than I think. </p>
<p>I am using the following code to listen for 'keyup' on a group of text input fields. If the user stops typing for a given amount of time, I send the data to a controller using AJAX. </p>
<p>I decided to try my hand at OOP in javascript to accomplish this. This is because I want a new instance of the timer method for each input field. (To be absolutely clear, Im very new to OOP in javascript so this might be dreadful. Let me know.)</p>
<p>Here is the main class with its methods:</p>
<pre><code> function FieldListener(entity){
t = this;
t.typingTimer; // Timer identifier
t.doneTypingInterval = 1000; // Time in ms. e.g.; 5000 = 5secs
t.entity = entity;
entity.bind("keyup", function(){t.setTimer();});
}
FieldListener.prototype.setTimer = function(){
t = this;
// User is still typing, so clear the timer.
clearTimeout(t.typingTimer);
// Get the field name, e.g.; 'username'
t.entityType = t.entity.attr("name");
// If the value is empty, set it to a single space.
if(!(t.val = t.entity.val())){
t.val = ' ';
}
t.noticeSpan = t.entity.siblings("span");
// Display 'waiting' notice to user.
t.noticeSpan.html('...')
t.typingTimer = setTimeout(function(){t.doneTyping();},t.doneTypingInterval);
}
FieldListener.prototype.doneTyping = function(){
// Encode for passing to ajax route.
t = this;
valueType = encodeURIComponent(t.entityType);
value = encodeURIComponent(t.val);
$.ajax({
url: '/check/'+valueType+'/'+value,
type: 'GET',
processData: false
})
.done(function(validationMessage){
t.noticeSpan.html(validationMessage);
})
.fail(function(){
t.noticeSpan.html("Something went wrong. Please try again.");
});
}
</code></pre>
<p>So from here I'd like to be able to create an object of the FieldListener class for every input field.</p>
<p>I know I can do it easily if I have an id for each like so:</p>
<pre><code> var fieldListener = new FieldListener($("#someFieldID"));
</code></pre>
<p>But I'd like to iterate over every field with a given class name. Something close to this perhaps?:</p>
<pre><code> i = 0;
$(".info-field").each(function(){
i = new FieldListener($(this));
});
</code></pre>
<p>But that doesn't work (and doesn't look very nice).</p>
<p>Any thoughts? (Im also curious about critiques/improvements to the class/methods code as well.)</p>
<p>edit: As per @ChrisHerring's question: The issue is that it seems to create the object but only for the last element in the each() method. So the span associated with the last input field with the class '.info-field' displays the validationMessage returned from AJAX regardless of which field I am typing in. </p>
<p>UPDATE:</p>
<p>It seems like something is wrong with the creation of new objects. For example, if, rather than iterating through the each() method, I simply follow one class initiation with another, like so:</p>
<pre><code> var fieldListener1 = new FieldListener($("#someFieldID"));
var fieldListener2 = new FieldListener($("#someOtherFieldID"));
</code></pre>
<p>that fieldListener2 overwrites variables being saved when initiating fieldListener1. This means that when I type into the input field with id "#someFieldID", it behaves as if I am typing into the input field with id "#someOtherFieldID". Thoughts?</p>
<p>UPDATE #2 (solved for now):</p>
<p>It seems that I have solved the issue for now. I needed to add 'var' before 't = this;' in the FieldListener class. Any comments/critiques are still welcome of course. ;)</p>

Grails: Hibernate and Data migrations
|
<p>I have a domain class that is for a customer. I have had to change to domain class recently because we were gathering a billing address and a shipping address, but were only recording one zip code value. So I thought what a simple fix. Change zipcode to billzipcode and then create a new field for shipzipcode. I ran dbm-gorm-diff to create the change log and then ran dbm-update to execute the changes I've made. Everything to this point works swimmingly. But then I go to debug the app to see that the changes to datasource were ok. However, now when I try to save a new customer record it get this error:</p>
<pre><code> NULL not allowed for column "ZIPCODE"; SQL statement:

how to make a axe throw and return sistem in unity
|
<p>guys,</p>
<p>so, i'm trying to make a game similar to the god of war in the unit, but i don't know how to make the ax return dynamically, eustou trying to make it come back without problems, but i still couldn't get a satisfactory result, i'm using an Animation to make the ax rotates and when it gets close enough to the player, the script deactivates the Animator and a Quaternion.Slerp Corrects the rotation of the ax, This is the code:</p>
<pre><code>using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class AxeController : MonoBehaviour {
// The axe object
public Rigidbody axe;
// Amount of force to apply when throwing
public float throwForce = 50;
// the target; which is the player's hand.
public Transform target;
// The middle point between the axe and the player's hand, to give it a curve
public Transform curve_point;
public Transform hand;
// Last position of the axe before returning it, to use in the Bezier Quadratic Curve formula
private Vector3 old_pos;
// Is the axe returning? To update the calculations in the Update method
private bool isReturning = false;
// Timer to link to the Bezier formual, Beginnning = 0, End = 1
public float time = 0.0f;
public float RotationSpeed;
public float MinDistance;
public float Distance;
public bool hasAxe = true;
public bool debounce = true;
public float gunDelay;
[Range (-10,10)]
public float TimeReduction;
[Range (0.1f , 100)]
public float VelocidadeDeAjuste;
// Update is called once per frame
void Update () {
Distance = Vector3.Distance(target.position, axe.transform.position);
// When the user/player hits the mouse left button
if (Input.GetButtonUp("Fire1") && hasAxe == true && debounce == true)
{
ThrowAxe();
debounce = false;
Invoke("debouncer" , gunDelay);
}
// When the user/player hits the mouse right button
if (Input.GetButtonUp("Fire1") && hasAxe == false && debounce == true)
{
ReturnAxe();
debounce = false;
Invoke("debouncer" , gunDelay);
}
// If the axe is returning
if(isReturning){
// Returning calcs
// Check if we haven't reached the end point, where time = 1
if(time < 1.0f){
// Update its position by using the Bezier formula based on the current time
axe.position = getBQCPoint(time, old_pos, curve_point.position, target.position);
// Reset its rotation (from current to the targets rotation) with 50 units/s
if (Distance > MinDistance) {
//axe.transform.localEulerAngles += Vector3.forward * Time.deltaTime;
Debug.Log("Nao Esta Distancia");
}
if (Distance <= MinDistance) {

}
else
{
axe.GetComponent<Animator>().enabled = true;
}
// Increase our timer, if you want the axe to return faster, then increase "time" more
// With something like:
// time += Timde.deltaTime * 2;
// It will return as twice as fast
time += Time.deltaTime/TimeReduction;
}else{
// Otherwise, if it is 1 or more, we reached the target so reset
ResetAxe();
}
}
}
// Throw axe
void ThrowAxe(){
// The axe isn't returning
isReturning = false;

DHCP Issue on home network
|
<p>I have an issue on my home office network - I'm not a networking expert in any way but I have a home network with a Samba NAS and an internal webserver for testing websites (my main role).
The PlusNet router is putting out DHCP in the range 192.168.1.100-199. Servers are fixed IP.
Client machines are picking up DHCP in the range 192.168.10.100- 200 with a default gateway of 192.168.10.1 - no devices on the network have this IP address and I cannot work out where this device is.</p>

Encoding does not switch when trying to read json file
|
<p>I have a json file <code>file.json</code> encoded KOI8-R.</p>
<p>Boost Json only works in UTF-8 encoding, so I'm converting the file from KOI8-R to UTF-8:</p>
<pre><code>boost::property_tree::ptree tree;
std::locale loc = boost::locale::generator().generate(ru_RU.UTF-8);
std::ifstream ifs("file.json", std::ios::binary);
ifs.imbue(loc)
boost::property_tree::read_json(ifs, tree);
</code></pre>
<p>However, the file cannot be read .. What am I doing wrong?</p>
<p><strong>UPDATE:</strong></p>
<p>I made up a JSON file "test.txt":</p>
<pre><code>{
"соплодие": "лысеющий",
"обсчитавший": "перегнавший",
"кариозный": "отдёргивающийся",
"суверенен": "носившийся",
"рецидивизм": "поляризуются"
}
</code></pre>
<p>And saved it in koi8-r.</p>
<p>I have a code:</p>
<pre><code>#include <boost/property_tree/ptree.hpp>
#include <boost/property_tree/json_parser.hpp>
int main() {
boost::property_tree::ptree pt;
boost::property_tree::read_json("test.txt", pt);
}
</code></pre>
<p>Compiled, ran and got the following error:</p>
<pre><code>terminate called after throwing an instance of 'boost::wrapexcept<boost::property_tree::json_parser::json_parser_error>'
what(): test.txt(2): invalid code sequence
Aborted (core dumped)
</code></pre>
<p>Then I use boost locale:</p>
<pre><code>#include <boost/property_tree/ptree.hpp>
#include <boost/property_tree/json_parser.hpp>
#include <boost/locale/generator.hpp>
#include <boost/locale/encoding.hpp>
int main() {
std::locale loc = boost::locale::generator().generate("ru_RU.utf8");
std::ifstream ifs("test.txt", std::ios::binary);
ifs.imbue(loc);
boost::property_tree::ptree pt;
boost::property_tree::read_json(ifs, pt);
}
</code></pre>
<p>Compiled (<code>g++ main.cpp -lboost_locale</code>), ran and got the following error:</p>
<pre><code>terminate called after throwing an instance of 'boost::wrapexcept<boost::property_tree::json_parser::json_parser_error>'

How to use LabelBinarizer to one hot encode both train and test correctly
|
<p>Suppose I have a train set like this:</p>
<pre><code>Name | day
------------
First | 0
Second | 1
Third | 1
Forth | 2
</code></pre>
<p>And a test set that does not contain all these names or days. Like so:</p>
<pre><code>Name | day
------------
First | 2
Second | 1
Forth | 0
</code></pre>
<p>I have the following code to transform these columns in encoded features:</p>
<pre><code>features_to_encode = ['Name', 'day']
label_final = pd.DataFrame()
for feature in features_to_encode:
label_campaign = LabelBinarizer()
label_results = label_campaign.fit_transform(df[feature])
label_results = pd.DataFrame(label_results, columns=label_campaign.classes_)
label_final = pd.concat([label_final, label_results], axis=1)
df_encoded = label_final.join(df)
</code></pre>
<p>To produce the following output on train (<strong>this works fine</strong>):</p>
<pre><code>First | Second | Third | Forth | 0 | 1 | 2 |
-----------------------------------------------
1 | 0 | 0 | 0 | 1 | 0 | 0 |
0 | 1 | 0 | 0 | 0 | 1 | 0 |
0 | 0 | 1 | 0 | 0 | 1 | 0 |
0 | 0 | 0 | 1 | 0 | 0 | 1 |
</code></pre>
<p>However, when I run this on test data (new data), I get <strong>mismatching features if the test data does not contain exactly all the same Names and days as train data</strong>. So if I run similar code on this test sample, I would get:</p>
<pre><code>First | Second | Forth | 0 | 1 | 2 |
--------------------------------------
1 | 0 | 0 | 0 | 0 | 1 |
0 | 1 | 0 | 0 | 1 | 0 |
0 | 0 | 1 | 1 | 0 | 0 |
</code></pre>
<p>What can I do to preserve the same transformation from train data and apply it correctly to test data, resulting in this <strong>desired output</strong>:</p>
<pre><code>First | Second | Third | Forth | 0 | 1 | 2 |
-----------------------------------------------
1 | 0 | 0 | 0 | 0 | 0 | 1 |
0 | 1 | 0 | 0 | 0 | 1 | 0 |
0 | 0 | 0 | 1 | 1 | 0 | 0 |
</code></pre>
<p>I have already tried adding a dict to catch the fit_transform results, but I am not sure if this works or what to do with it afterwards:</p>
<pre><code>features_to_encode = ['Name', 'day']
label_final = pd.DataFrame()
labels = {}--------------------------------------------------------------------> TRIED THIS
for feature in features_to_encode:
label_campaign = LabelBinarizer()
label_results = label_campaign.fit_transform(df[feature])
labels[feature] = label_results--------------------------------------------> WITH THIS
label_results = pd.DataFrame(label_results, columns=label_campaign.classes_)
label_final = pd.concat([label_final, label_results], axis=1)
df_encoded = label_final.join(df)
</code></pre>
<p>Any help is appreciated. Thanks =)</p>

Missing on data with Group by and Sum

<p>I tried using group by, but only got the first amount record for each table:</p>
<pre><code>Select A.Order_Number, A.Amount, B.Amount
From Table_A as A
Left Join (Select Order_Number, Amount From Table_B) as B
On A.Order_Number = B.Order_Number
Group By A.Order_Number
Invoice_ID | Amount_Table_A | Amount_Table_B |
01 | 80 | 20 |
</code></pre>
<p>I tried adding the sum() clause to each amount attribute in the select statement and got the sum of each repeated record:</p>
<pre><code>Select A.Order_Number, sum(A.Amount), sum(B.Amount)
From Table_A as A
Left Join (Select Order_Number, Amount From Table_B) as B
On A.Order_Number = B.Order_Number
Group By A.Order_Number
Invoice_ID | Amount_Table_A | Amount_Table_B |
01 | 2400 | 800 |
</code></pre>
<p>how may I modify this query to show the real value?? Expected value is:</p>
<pre><code> Invoice_ID | Amount_Table_A | Amount_Table_B |
01 | 200 | 200 |
</code></pre>
<p>Please keep in mind that this is an over simplified data set. The real table has over a million records and I need to make sure that the Invoice_ID adds up to the same total in both tables.</p>
<p>Thank you so much!!!</p>

Flutter error in Android Studio (Windows): Unrecognized option: --add-opens
|
<p>I have been working on a Flutter application that I've successfully run on both an Android emulator and a physical device during the past couple of weeks. Somehow and all of a sudden, I'm unable to run it in debug mode.
I tried several answers found in SO but they all seem to be hacks that don't really fix the issue.</p>
<h3>The Error</h3>
<p>When I tried to run the application, an error is thrown from Gradle daemon because it could not create a JVM as seen in the screenshot below...</p>
<p><a href="https://i.stack.imgur.com/yn31p.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/yn31p.png" alt="enter image description here" /></a></p>
<pre><code>Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Unrecognized option: --add-opens
</code></pre>
<h3>Possible cause???</h3>
<p>I remember I upgraded the Gradle Plugin to I-don't-know-what-version, I wasn't really paying attention to it (my bad) but I kept on working without any issues. Then, I upgrade Flutter to version 2.2.2, that's when the issue started to creeping in (Maybe).</p>
<h3>Supporting Info</h3>
<p>OS: Windows Server 2016 Standard (x64)<br />

javascript get value of Mongo field already rendered - Meteor
|
<p><em>Hey everyone, thank you very much for your help. Question is edited per suggestions in the comments.</em></p>
<p>I'm new to Mongo and Meteor.</p>
<p>I have a collection "posts" with a field "slug".</p>
<p>The "post" template is populating correctly with each post's values. Slug value is always something like "my-great-post".</p>
<p>I need to get the text value for the _id's slug, which will be different each time the template is accessed, encode it, write a string, and spit the string back out into the template. </p>
<p><strong>Things tried</strong></p>
<ul>
<li><p>can't return a value for "this.slug" or "this.data.slug" in either template helpers or onRendered, even though collection is defined and correctly populating spacebars values in the template</p></li>
<li><p>"this" returns "[object Object]" to console.log</p></li>
<li><p>app crashes when I try to javascript encode and deliver a string from the helper, probably I don't fully understand helper syntax from the documentation</p></li>

How to dispatch Redux action without "onClick"?

How to write an aspect to cater to different objects and method arguments
|
<p>I am looking to write an Aspect which can be used to mock data depending on some value passed in the method. This mock will replace the actual REST call. If the value doesn't match, go back to the actual method and make the call to the REST endpoint.</p>
<p>I already have an aspect written that works in production but is very messy and had to implement multiple different methods in there to accommodate the need to return different objects and handle different method arguments. Is there a way I could generalise this so that I could have like a single method to perform the work and able to use if for future cases where I do not have to worry about object types and method signatures.</p>
<p>Current implementation as follows. How could I amend this to work as a single method which can cater to future methods and response types without having to change my Aspect? </p>
<p>To clarify I have the following 3 methods which I want to mock by using Aspect. as you can see I have a custom annotation that takes in a name. None of the method's arguments line up. </p>
<pre><code>@MyMock(name = "ABC")
public AResponse getAResponse(ARequest aRequest){
// make a REST call
}
@MyMock(name = "DEF")
public BResponse getBResponse(String fruit, BRequest bRequest){
// make a REST call
}
@MyMock(name = "GHJ")
public CResponse getCResponse(String vehicle, CRequest cRequest, int id){
// make a REST call
}
</code></pre>
<p>The Aspect Class currently is as follows. I use the name value in the annotation to determine which method to call and which value type to return. As you can see this is not very scalable. I need to write a new method and logic every single time I implement new mocks. </p>
<pre><code>@Around("@annotation(myMock)")
public Object getMockedData(ProceedingJoinPoint pjp, MyMock myMock) throws Throwable {
String servName = performMocking.name();
Object[] methodArguments = pjp.getArgs();
MethodSignature signature = (MethodSignature) pjp.getSignature();
Class returnType = signature.getReturnType();
switch (myMock.name()) {
case "ABC":
getA(methodArguments[0]);
break;
case "DEF":
getB(methodArguments[0]);
break;
case "GHJ":
getC(methodArguments[2]);
break;
}
return pjp.proceed(methodArguments);
}
private AResponse getA(ARequest aRequest){
// I use methodArguments[0] (which is aRequest) to decide what value to return as a mock response here.
// There is a getName value in that object which I use to reference
}
private BResponse getB(BRequest bRequest){
// I use methodArguments[0] (which is a String) to decide what value to return as a mock response here.
}
private CResponse getC(CRequest cRequest){
// I use methodArguments[2] (which is an int) to decide what value to return as a mock response here.
}
</code></pre>
<p>All the above get methods makes a call to an external JSON file to fetch the mock data. The files content as follows. If the keys match, a mock response would be given else go back to making actual REST call. </p>
<pre><code>{
"ABC": {
"enabled": "true",
"responses": [
{
"a_name": "{some valid json response matching the AResponse Object structure}"
}
]
},
"DEF": {
"enabled": "true",
"responses": [
{
"d_name": "{some valid json response matching the BResponse Object structure}"

"enabled": "true",

Group books and get count for each of their ratings
|
<p>I have a Rating model with a book and rating value to it. I would like to get all the ratings count (ratings vary from 1 to 5) for each book in the database.</p>
<p>My schema simply looks like - </p>
<pre><code> {
"_id": ObjectId("57e112312a52fe257e5d1d5c"),
"book": ObjectId("57e111142a52fe257e5d1d42"),
"rating": 4
}
{
"_id": ObjectId("57e7a002420d22d6106a4715"),
"book": ObjectId("57e111142a52fe257e5d1d42"),
"rating": 5
}
{
"_id": ObjectId("57e7a4cd98bfdb5a11962d54"),
"book": ObjectId("57e111142a52fe257e5d17676"),
"rating": 5
}
{
"_id": ObjectId("57e7a4cd98bfdb5a11962d54"),
"book": ObjectId("57e111142a52fe257e5d17676"),
"rating": 1
}
</code></pre>
<p>Currently, i have only been able to get to this point where i can get the no of ratings for each book but it doesn't specify exactly the rating value count.</p>
<p>This is my current query - </p>
<pre><code> db.ratings.aggregate([
{$match: {book: {$in: [ObjectId("57e111142a52fe257e5d1d42"), ObjectId('57e6bef7cad79fa38555c643')]}}},
{$group: {_id: {book: "$book", value: "$value"} } },
{$group: {_id: "$_id.book", total: {$sum: 1}}},
])
</code></pre>
<p>The output is this - </p>
<pre><code> {
"result": [
{
"_id": ObjectId("57e6bef7cad79fa38555c643"),
"total": 2
},
{
"_id": ObjectId("57e111142a52fe257e5d1d42"),
"total": 2
}
],
"ok": 1
}
</code></pre>
<p>However, i want to club all the documents and get a result with the count of ratings for each value of the <code>rating</code> field, something like below. The whole point is that i just want the count of ratings for each value for each book.</p>
<pre><code> {
result: [
{
_id: "57e111142a52fe257e5d17676",
5_star_ratings: 1,
4_star_ratings: 3,
3_star_ratings: 4,
2_star_ratings: 1,
1_star_ratings: 0,
},
{
_id: "57e111142a52fe257e5d1d42",
5_star_ratings: 10,
4_star_ratings: 13,
3_star_ratings: 7,
2_star_ratings: 8,
1_star_ratings: 19,
}

UIView.animate not executed in PHPhotoLibrary.shared().performChanges
|
<p>I have been working on the following code for the entire day now and simply cannot find the problem. I would like to save a video and upon completion make certain buttons or spinners (dis-)appear. All the buttons are setup in the <code>viewDidLoad</code> and so to say exist (they're optionals, therefore also the optional chaining). My problem is the animations in the <code>if</code> clause are never executed. Only sometimes if I place breakpoints before every line of code, it works which really makes me wonder (btw: the breakpoints don't indicate anything unusual). Further, if I replace the code of the <code>if success2 == true</code> with the code of the <code>else</code> (<code>if success2 == false</code>), it works (after the alert pops up). I pretty much quadruple-checked my code and just cannot find what I am doing wrong. Has anyone an idea as to what could be the problem and how it could be solved? </p>
<p>Sorry for the huge block of code:</p>
<pre><code>PHPhotoLibrary.shared().performChanges({
if let assetChangeRequest = PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: url) {
let assetCollectionChangeRequest = PHAssetCollectionChangeRequest(for: albumAssetCollection)
let enumeration: NSArray = [assetChangeRequest.placeholderForCreatedAsset!]
assetCollectionChangeRequest?.addAssets(enumeration)
}
}, completionHandler: { (success2: Bool, error2: Error?) in
if success2 == true {
// prompt that the video has been saved
UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 1, initialSpringVelocity: 1, options: .curveEaseOut, animations: {
if let checkButton = self.checkButton, let saveSpinner = self.saveSpinner, let resetButton = self.resetButton {
saveSpinner.alpha = 0
checkButton.alpha = 1
resetButton.alpha = 1
}
}) { (completed: Bool) in
if completed == true {
if let saveSpinner = self.saveSpinner {
saveSpinner.stopAnimating()
self.timeLimitReached = false
self.changeClipsCount()
}
UIView.animate(withDuration: 0.5, delay: 3, usingSpringWithDamping: 1, initialSpringVelocity: 1, options: .curveEaseOut, animations: {
if let checkButton = self.checkButton, let saveButton = self.saveButton {
checkButton.alpha = 0
saveButton.alpha = 1
}
}) { (completed: Bool) in }
}
}
} else {
// prompt that the video has not been saved
let alertController = UIAlertController(title: "Something failed!", message: "The video could not be saved.", preferredStyle: .alert)
let okAction = UIAlertAction(title: "OK", style: .default, handler: nil)
alertController.addAction(okAction)
self.present(alertController, animated: true, completion: {
UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 1, initialSpringVelocity: 1, options: .curveEaseOut, animations: {
if let saveButton = self.saveButton, let saveSpinner = self.saveSpinner {
saveButton.alpha = 1
saveSpinner.alpha = 0
}
}) { (completed: Bool) in
if let saveSpinner = self.saveSpinner {
saveSpinner.stopAnimating()
self.timeLimitReached = false
}
}
})
}

Bound checking for empty arrays --- behavior of various compilers
|
<p><strong>Update</strong> 20210914: Absoft support confirms that the behavior of <code>af95</code> / <code>af90</code> described below is unintended and indeed a bug. Absoft developers will work to resolve it. The other compilers act correctly in this regard. Thank @Vladimir F for the answer, comments, and suggestions.</p>
<hr />
<p>I have the impression that Fortran is cool with arrays of size 0. However, with Absoft Pro 21.0, I encountered a (strange) error involving such arrays. In contrast, <code>gfortran</code>, <code>ifort</code>, <code>nagfor</code>, <code>pgfortran</code>, <code>sunf95</code>, and <code>g95</code> are all happy with the same piece of code.</p>
<p>Below is a minimal working example.</p>
<pre><code>! testempty.f90
!!!!!! A module that offends AF90/AF95 !!!!!!!!!!!!!!!!!!!!!!!!
module empty_mod
implicit none
private
public :: foo
contains
subroutine foo(n)
implicit none
integer, intent(in) :: n
integer :: a(0)
integer :: b(n - 1)
call bar(a) ! AF90/AF95 is happy with this line.
call bar(b) ! AF90/AF95 is angry with this line.
end subroutine foo
subroutine bar(x)
implicit none
integer, intent(out) :: x(:)
x = 1 ! BAR(B) annoys AF90/AF95 regardless of this line.
end subroutine bar
end module empty_mod
!!!!!! Module ends !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!! Main program !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
program testempty
use empty_mod, only : foo
implicit none
call foo(2) ! AF90/AF95 is happy with this line.
call foo(1) ! AF90/AF95 is angry with this line.
write (*, *) 'Succeed!' ! Declare victory when arriving here.
end program testempty
!!!!!! Main program ends !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
</code></pre>
<p>Name this piece of code as <code>testempty.f90</code>. Then run</p>
<pre><code>$ af95 -no-pie -et -Rb -g -O0 -o atest testempty.f90
$ ./atest
</code></pre>
<p>This is what happened on my machine (Ubuntu 20.04, linux 5.4.0-77-generic, x86_64):</p>
<pre><code>./atest
? FORTRAN Runtime Error:
? Subscript 1 is out of range for dimension 1 for array

</code></pre>
<p>So <code>af95</code> was annoyed by <code>call bar(b)</code>. With <code>af90</code>, the result was the same.</p>
<p>I tested the same code using <code>gfortran</code>, <code>ifort</code>, <code>nagfor</code>, <code>pgfortran</code>, <code>sunf95</code>, and <code>g95</code>. All of them were quite happy with the code even though I imposed bound checking explicitly. Below is the <code>Makefile</code> for the tests.</p>

<p><strong>Questions:</strong></p>
<ol>
<li>Is the behavior of <code>af95</code>/<code>af90</code> standard-conforming?</li>
<li>Does my code contain anything that violates the Fortran standards?</li>
<li>In general, is it considered dangerous to involve empty arrays in Fortran code? Sometimes they are inevitable given the fact the data sizes are often undecidable before runtime.</li>
</ol>
<p>By "standards", I mean 2003, 2008, and 2018.</p>
<p>Thank you very much for any comments or criticism.</p>
<p>(The same question is posed on <a href="https://fortran-lang.discourse.group/t/bound-checking-for-empty-arrays-behavior-of-various-compilers/1828" rel="nofollow noreferrer">Fortran Discourse</a>, and I hope it does not violate the rules here.)</p>

Uploading text file dictionary to python dictionary is not working

<p>now I need to open product.txt file and read the content back into a dictionary in python. This is one of many codes i tried.</p>
<pre><code>def uploadProductDir():

<p>but i am getting this error</p>
<blockquote>
<p>Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)</p>
</blockquote>
<p>how could I upload a text file containing dictionary data format above in python so that i can iterate through the dictionary. This was a python json dictionary that i mistakenly saved to a .txt instead of .json file. Now I want to import from the .txt file back in python so that i can work with the data.</p>

Duplicate navigation property cannot be used due to single relationship error
|
<p>I am trying to solve a relatively simple setup but am wondering if there is a better way to set this relation one. </p>
<p>I have a User class that is the starting point for all other relationships. Every other class unless specific conditions are met has a 1-to-many relationship to the User class (e.g. MenuItems is just one of them, there are other classes with the same relationship).</p>
<p>I have a MenuItem class that has has the UserId as the foreign key. I also want to track the user that last updated the item. But if I add the <code>LastUpdatedById</code> and <code>LastUpdatedBy</code> properties, EF core will throw an error due to the navigation property <code>User</code> participating in more than one relationship. </p>
<p>The whole point I was trying to solve this was when fetching the items, to include the <code>Created</code> and <code>LastUpdatedBy</code> properties so that I can easily access the user name + id. <strong><em>Is there a way to solve this or is the only option to make this a many-to-many relationship? If so, what would be the best method to accomplish that?</em></strong></p>
<p>The simplest option would be to make the properties string values and just update them during relevant CRUD operations but I wanted this to be a little more dynamic.</p>
<pre><code>public class User
{
[Key]
public Guid Id { get; set; }
[Required]
public string Name { get; set; }
[Required]
public DateTime Created { get; set; }
public ICollection<MenuItem> MenuItems { get; set; }
}
public class MenuItem
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
public ItemType Type { get; set; }
[Required]
public DateTime Created { get; set; }
public int? ParentMenuItemId { get; set; }
public MenuItem ParentMenuItem { get; set; }
public ICollection<MenuItem> ChildMenuItems { get; set; }
[Required]
public Guid UserId { get; set; }
[Required]
public User CreatedBy { get; set; }
[Required]
public Guid LastUpdatedById { get; set; }
[Required]
public User LastUpdatedBy { get; set; }
}
</code></pre>
<hr>
<p>Thanks to David for my solution. I ended up going a slightly different route based on his answer:</p>
<p>I created below 2 properties and deleted the original collection of MenuItem from User. </p>
<pre><code>public ICollection<MenuItem> UpdatedMenuItems { get; set; }
public ICollection<MenuItem> CreatedMenuItems { get; set; }
</code></pre>
<p>I also used fluent API to explicitly define the relationship to make it fully defined.</p>
<pre><code>modelBuilder.Entity<MenuItem>()
.HasOne(x => x.CreatedBy)
.WithMany(x => x.CreatedMenuItems)
.HasForeignKey(x => x.UserId)
.OnDelete(DeleteBehavior.Cascade);
modelBuilder.Entity<MenuItem>()
.HasOne(x => x.LastUpdatedBy)
.WithMany(x => x.UpdatedMenuItems)
.HasForeignKey(p => p.LastUpdatedById)
.OnDelete(DeleteBehavior.Restrict);

Error in creating a virtual machine in using vagrant

It seems that there are no syntax errors or something missing.
If somebody has had the same problem can you please share with me the solution?

App freezes when a tableViewController is opened
|
<p>First want to know how can I debug where the issue is, what is stalling the main thread indefinitely. I read somewhere that as soon as my app freezes, i should pause it and see the threads and i'll able to see what is taking up so long. I did that but I cant identify the cause.
<a href="https://i.stack.imgur.com/J0Yhq.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/J0Yhq.png" alt="Screenshot of threads in frozen app state"></a></p>
<p>Secondly, I should also mention my scenario because the freeze is always reproducible. I open a <code>tableViewController</code>on tap of a <code>UILabel</code> (through <code>TapGestureRecongniser</code>). The user can select multiple cells in the <code>tableViewController</code> and the <code>UILabel</code> reflects the values, user selected in <code>tableViewController</code>. I have a central ContentManager which handles the content of the app. The <code>tableViewController</code> changes a list in the <code>ContentManager</code> and <code>UILabel</code> fetches that list to update it self. Everything is working fine till here. If I open the <code>TableViewController</code> again, the app freezes. This only happens if the user has changed the selected cells. If user opens <code>tableViewController</code> but does not change any cell's selected state and presses back, app does not freezes on opening it again. This is code of my <code>tableViewController</code></p>

Remove a node from the following XML.
|
<p>This is the xml I got as an output from the <code>WriteXmlString()</code> of <code>Infragistics ultrawebtree</code>. I am using this to create another <code>Infragistics ultrawebtree</code> with the same structure. But here I don't want the <code><Url>something.aspx..</Url></code>. I want that to be like this <code><Url><\Url></code>. So how I can able to remove. This I get as a String. So I used <code>Regex.Replace()</code>. But it will work for certain conditions,but for some case it will destruct the xml by deleting some xml tags and xml became not valid due to missing of tags.
I used this expression <code><Url>\S*</Url></code> to avoid the contents of Url. Any help will be very helpful. Thanks in advance.</p>

<p>I'm sure this is something really easy, but I've been at it for a few days and tried many different things, including many attempts of resizing.</p>
<p>So why does the last element skip down to the next level, but only at different zooms? When I resize it to fit one zoom level, it looks completely different in another. Is there a way to get this to always fill the 954px #bar element no matter the zoom?</p>

Python - write to CSV from multiple JSON files
|
<p>I have been trying and failing all day to write multiple JSON files I am pulling from the nys.gov website on COVID data to one (or more) CSV files.</p>
<p>I can successfully concatenate the JSON files but have not been able to but them together in a format I can utilize to make graphs. I know the issue is somewhere in my for loop but after many attempts I have not found a successful method of either appending the data into one csv or creating multiple csv files I can then work with in pandas. Here is my code, currently it seems it is iterating through the loops and dumping the final json into my csv...</p>
<pre><code>import csv
import datetime
import json

one_day = datetime.datetime.today() - datetime.timedelta(days=1)

<p>I'm probably somewhere between beginner and intermediate with python so please forgive any poor coding practices. Thanks in advance.</p>
