74,340,788 | <p>Blazor's <code>NavLink</code> component detects whether the link refers to the current page, and sets the <code>active</code> class.</p>
<p>It is customary to also set the <code>aria-current="page"</code> attribute, when it is part of a menu.</p>
<p>Can the component do that somehow? Or could I wrap it in a custom component that does this?</p>
<p>I can't find an extension point that easily allows for this: <a href="https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.components.routing.navlink?view=aspnetcore-6.0" rel="nofollow noreferrer">docs</a>, <a href="https://github.com/dotnet/aspnetcore/blob/ce78832442d91ca307ca8366bafdc9003ea46bc9/src/Components/Web/src/Routing/NavLink.cs" rel="nofollow noreferrer">source</a>.</p>

74,340,857 | <p>I am relatively new to javascript and am trying to get the last line of text in a a textarea on a key press. Is this possible? My code is below.</p>
<pre class="lang-js prettyprint-override"><code>
const textarea = document.getElementById('textarea');
textarea.addEventListener("keydown", (event) => {
if (event.code != 13) {
return "Enter key was not pressed"
}
else if(event.code === 13) {
//Do what my question is asking
}
});
</code></pre>
<p>I have tried to get the innerHTML property and the value property of the textarea but that returned the full contents of the textarea, not the last line which is what I need.</p>
<pre><code>const textarea = document.getElementById('textarea');
//First thing I tried
let content = textarea.innerHTML;
console.log(content);
//Second thing I tried
let content2 = textarea.value;
console.log(content2);

<pre><code>private string GenerateBarcode(string BarCode)

string generatebarcode = BarCode;
GeneratedBarcode barcode = BarcodeWriter.CreateBarcode(generatebarcode, BarcodeWriterEncoding.Code128);

string temp_inBase64 = Convert.ToBase64String(myArray);
return temp_inBase64;
}
</code></pre>
<p>And after this, I'm saving this BASE64 into my database.</p>
<p>Now, getting this into my Dataset, showing in tabular form.</p>
<p>At the RDLC level, I've tried:</p>
<ul>
<li>Drop an Image report control from toolbox.</li>
<li>Right click on the image and choose image properties</li>
<li>Set the image source to database</li>
<li>Set the MIME type to a suitable value, for example image/bmp.</li>
<li>Set use this field to the image value which you have,</li>
</ul>
<p>For example <code>=Fields!Code.Value</code>. The parameter type should be Text.</p>
<p>But it's not showing anything in the RDLC Report Viewer.</p>
<p>I've found many solutions on the internet but none of them seems works to me. Is there something that I missed?</p>
<p>I use Visual Studio 2019 Community, .NET Framework 4.7.2, <code>Microsoft.ReportViewer.WebForms</code> 15.0.0.0</p>
<p>Thanks.</p>

74,340,913 | <p>I am working on a project with a React front-end and a Laravel back-end. I am trying to set up my authentication system. I am utilizing SPA authentication using Sanctum. I am successfully utilizing the sanctum/csrf-cookie route, where the XSRF-Token cookie is given. When I then try to follow that up with a login, I get a 419 error, CSRF token mismatch. There is no XSRF-Token. What is interesting is that if I do a get request, as in the 'testing' route below, the XSRF cookie is present. However, when I do a post request, as in posting to the login route, the cookie is not present and I get a 419 error.</p>
<p>I am running this locally right now. The front-end is running at localhost:3000, with the back-end running at localhost:8888. Here are various relevant segments of code.</p>

74,340,962 | <p>I have a widget in my settings screen something like this:</p>
<pre><code>Widget autoplay()
{
return ChangeNotifierProvider<AutoplayToggle>(
create: (context) => AutoplayToggle(),
child: Consumer<AutoplayToggle>(
builder: (context, provider, child) {
return Container(
color: provider.isPause ? accent : primary,
width: 45,
child: Switch.adaptive(
value: isPause,
onChanged: (value) async {
setState(() {
isPause= value;
});
await UserPrefs.setAutoplay(isPause);
provider.toggleAutoplay();
},
),
);
},
),
),
}
</code></pre>
<p>and this is my class:</p>
<pre><code>class AutoplayToggle with ChangeNotifier{
bool isPause = false;
void toggleAutoplay()
{
isPause = !isPause;
print(isPause);
notifyListeners();
}
}
</code></pre>
<p>I printed couple of statements to debug and every time I toggle the switch the function is being called as the values will change from false to true, however, it is not notifying the change. Any idea on whats going wrong?</p>

74,340,992 | <p>Currently developing a REST API, with a suite of endpoint functions which update the "state" of a particular resource.</p>
<p>I am using POST to create the initial resource and then updating the state using PUT - Is PUT the correct method to be using?</p>
<p>The state updates are being logged in a journal, so to avoid someone updating the state with the same value multiple times, I wish to put some business logic in that avoid two repeat entries of the same state. If someone attempts to call the same function twice, lets say "CancelResource()" - should I return a 200 success on the second call, and just not make an update, or would it be better to send some sort of error response?</p>
<p>I was considering returning a 405 "method not allowed" but this feels a little <em>harsh</em>. I also don't know that 200 would be very useful for the client.</p>

74,340,996 | <p>I am trying to migrate my map here over to using getx state management. How do I convert the setstate() portion? I want to use a stateless widget. I have a separate view and controller.</p>
<p>This my MapPage code here. It is still a stateful widget as I could not figure out how to address the setstate portion in my getx LocationController. Basically I need to show the LoadScreen while the GoogleMap loads.</p>
<pre><code>class MapsPage2 extends StatelessWidget {
final GoogleMapController _googleMapController =
Get.put(GoogleMapController());
@override
Widget build(BuildContext context) {
return Scaffold(
body: Obx(
() => locationController.currentLatLng == null
? LoadScreen()
: Stack(
children: [
Container(
child: GoogleMap(
initialCameraPosition: CameraPosition(
//get user location
target: locationController.currentLatLng!,
zoom: 16),
minMaxZoomPreference: MinMaxZoomPreference(15.5, 19),
zoomGesturesEnabled: true,
cameraTargetBounds: CameraTargetBounds(
LatLngBounds(
northeast: LatLng(43.7970928, -79.3067414),
southwest: LatLng(43.592580, -79.483674),
),
),
),
),
],
),
));
}
}
</code></pre>
<p>How will I need to edit my location controller?</p>
<pre><code>class LocationController extends GetxController {
static LocationController instance = Get.find();
Position? myLocation;
Rx<Geolocator>? geolocator = Geolocator().obs;
LatLng? currentLatLng;
RxBool isLoading = false.obs;
@override
void onInit() async {
super.onInit();
getpermission();
}
getpermission() async {
bool serviceEnabled;
LocationPermission permission;
serviceEnabled = await Geolocator.isLocationServiceEnabled();
if (!serviceEnabled) {
await Geolocator.openLocationSettings();
return Future.error("location service is not enabled");
}
permission = await Geolocator.checkPermission();
if (permission == LocationPermission.denied) {
//do stuff here
permission = await Geolocator.requestPermission();
if (permission == LocationPermission.denied) {
//stuff
return Future.error("location permissions denied");
}
}
if (permission == LocationPermission.deniedForever) {
return Future.error("location permissions permanently denied");
}
myLocation = await Geolocator.getCurrentPosition(
desiredAccuracy: LocationAccuracy.high);
}
//next func here
}
</code></pre>
<p>And this is the error I am currently getting in terminal:</p>
<pre><code>The following message was thrown building Obx(has builder, dirty, state:
_ObxState#66e23):
[Get] the improper use of a GetX has been detected.
You should only use GetX or Obx for the specific widget that will be updated.
If you are seeing this error, you probably did not insert any observable variables
into
GetX/Obx
or insert them outside the scope that GetX considers suitable for an update
(example: GetX => HeavyWidget => variableObservable).
If you need to update a parent widget and a child widget, wrap each one in an
Obx/GetX.
The relevant error-causing widget was:
Obx

<ul>
<li>telnet private-ip 22 -> works fine</li>

<p>It works perfectly but I can't get how to set an own colour for every tab icon. I've tried all possible methods already <code>foregroundColor()</code>, <code>accentColor()</code>, <code>tint()</code> and so on... A nothing works. It changes a color of all tab icons or no one icon.</p>
<p>How to make it in <code>TabView</code>?</p>

74,341,093 | <p>I have a VideoPlayer component with crop functionality that's not working well after migration to functional over class component.</p>
<p>The VideoPlayer has a isVideoPlaying state (useState).
It also contains a function toggleOrChangeIsVideoPlaying:</p>
<pre><code>const togglePlayPauseVideo = (toPlay) => {
if (toPlay !== undefined) {
if (toPlay) {
playVideo()
} else {
pauseVideo()
}
} else {
if (!isVideoPlaying) {
playVideo()
} else {
pauseVideo()
}
}
}
</code></pre>
<p>It renders:</p>
<pre><code><div>
<Crop onPlayPauseVideo={togglePlayPauseVideo} ...restofTheProps>
<Video ...someProps />
</Crop>
</div>
</code></pre>
<p>Using useEffect & console.log() I verified that 'togglePlayPauseVideo' function is changing (and causing a bug), probably because VideoPlayer is re-rendered.</p>
<p>I've tried wrapping 'togglePlayPauseVideo' with useCallback. The problem is that it must have 'isVideoPlaying' state as a dependency (otherwise there's another bug), but when it does, it changes again more than it should.</p>
<p>Any ideas how to break this cycle?</p>
<p>BTW 1: 'isVideoPlaying' state is needed to keep track of the actual element state, that changes in playVideo() and pauseVideo() via ref.</p>
<p>BTW 2: VideoPlayer worked ok when it was a class component.</p>

74,341,130 | <p>I need a JavaScript function that allows to select only two divs out of several and insert them respectively into others. My code has 15 .item and 4 .item2. I'm developing an app that generates essay templates. The .item are keyword arguments that need to be included in a predicate structure (class .item2, which has 2 .main_place divs - it takes 2 arguments out of 15). I would like to create a function where the button to insert some .item in the .main_place is the .item itself, so that the user can define the order of presentation of arguments in the predicate based on what he selected.</p>
<pre><code><div class="item" id="arg1">first block</div>
<div class="item" id="arg2">second block</div>
<div class="item" id="arg3">third block</div>
<div class="item2">put the first block <div class="main_place">here</div> and the second one <div class="main_place">here</div>.</div>
</code></pre>
<p>I saw a solution here on stackoverflow (<a href="https://stackoverflow.com/questions/37347690/how-to-replace-div-with-another-div-in-javascript">How to replace div with another div in javascript?</a>), but it doesn't solve my problem. btw if I have to create a button, I would like the item div itself to be one</p>
<pre><code>function show(param_div_id) {
document.getElementById('main_place').innerHTML =
document.getElementById(param_div_id).innerHTML;
}

74,341,139 | <p>I have an image that I read in with <code>tifffile.imread</code> and it is turned into a 3D matrix, with the first dimension representing the Y coordinate, the second the X and the third the channel of the image (these images are not RGB and so there can be an arbitrary number of channels).</p>
<p>Each of these images has a label mask which is a 2D array that indicates the position of objects in the image. In the label mask, pixels that have a value of 0 do not belong to any object, pixels that have a value of 1 belong to the first object, pixels that have a value of 2 belong to the second object and so on.</p>
<p>What I would like to calculate is for each object and for each channel of the image I would like to know the mean, median, std, min and max of the channel. So, for example, I would like to know the mean, mediam std, min and max values of the first channel for pixels in object 10.</p>
<p>I have written code to do this but it is very slow (shown below) and I wondered if people had a better way or knew a package(s) that might be helpful i making this faster/doing this more efficiently. (Here the word 'stain' means the same as channel)</p>
<pre><code>sample = imread(input_img)
label_mask = np.load(input_mask)
n_stains = sample.shape[2]
n_labels = np.max(label_mask)
#Create empty dataframe to store intensity measurements
intensity_measurements = pd.DataFrame(columns = ['sample', 'label', 'stain', 'mean', 'median', 'std', 'min', 'max'])
for label in range(1, n_labels+1):
for stain in range(n_stains):
#Extract stain and label
stain_label = sample[:,:,stain][label_mask == label]
#Calculate intensity measurements
mean = np.mean(stain_label)
median = np.median(stain_label)
std = np.std(stain_label)
min = np.min(stain_label)
max = np.max(stain_label)
#Add intensity measurements to dataframe
intensity_measurements = intensity_measurements.append({'sample' : args.input_img, 'label': label, 'stain': stain, 'mean': mean, 'median': median, 'std': std, 'min': min, 'max': max}, ignore_index=True)

74,341,209 | <p>In Python, many statements can cause errors, but I would like to know what are the simplest statements that can cause an Error <strong>except</strong> for <code>NameError</code> and <code>SyntaxError</code> and their subclasses such as <code>IdentationError</code></p>
<p>Using the interactive Python shell, I have tried using single characters in statements but they are all <code>NameError</code>s or <code>SyntaxError</code>s, and I tried two characters, it is also the same, so I wonder if there are any possibilities to cause other types of errors by using 3 or fewer characters in Python. if this is impossible, then why so?</p>

74,341,211 | <p>When I'm working on a website, I check the changes on my browser (Google Chrome), and since usually the browser doesn't register the changes I make into the CSS file, I usually just work into an incognito window to avoid the hassle of deleting the cache manually. The downside is that I have to close it and open it often, and I have to log again in the app I'm working on every single time.
This is relatively quickly but it adds up over time when done hundreds of times.</p>
<p>There has to be a better way. What do most programers do?</p>

74,341,221 | <p>I am trying to use Pybind11 in a Cmake project. I'm using Cmake 3.23.0-rc2.</p>
<p>To include it, I can do the following:</p>
<p><code>find_package(pybind11 REQUIRED)</code></p>
<p>However, this does not work on my machine. So, I attempted to give find_package a hint as per the user guide:</p>
<pre><code>SET(pybind11_DIR, "C:/Users/tyler.shellberg/AppData/Local/Programs/Python/Python37/Lib/site-packages/pybind11")
</code></pre>
<p>That did not work either. The Cmake error suggested it may need to be the specific location of files like <code>pybind11Config.cmake</code>. So, I tried being more specific:</p>
<pre><code>SET(pybind11_DIR, "C:/Users/tyler.shellberg/AppData/Local/Programs/Python/Python37/Lib/site-packages/pybind11/share/cmake/pybind11")
</code></pre>
<p>That doesn't work either. I get the exact same error in Cmake:</p>
<pre><code>CMake Error at lib/(our project name)/CMakeLists.txt:30 (find_package):
By not providing "Findpybind11.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "pybind11",
but CMake did not find one.
Could not find a package configuration file provided by "pybind11" with any
of the following names:
pybind11Config.cmake
pybind11-config.cmake
Add the installation prefix of "pybind11" to CMAKE_PREFIX_PATH or set
"pybind11_DIR" to a directory containing one of the above files. If
"pybind11" provides a separate development package or SDK, be sure it has
been installed.
</code></pre>
<p>I double checked, Python itself is being found:</p>
<pre><code>Python_FOUND:TRUE
Python_VERSION:3.7.4
Python_Development_FOUND:TRUE
Python_LIBRARIES:C:/Users/tyler.shellberg/AppData/Local/Programs/Python/Python37/libs/python37.lib

</code></pre>
<p>(Though weirdly, include_dirs is empty)</p>
<p>What am I doing wrong?</p>

<p>But I want:</p>

2022-11-08
2022-11-09

74,341,259 | <p>I am testing a URL in flutter, but keep getting an error:</p>
<blockquote>
<p>Error: The argument type 'String' can't be assigned to the parameter type 'int'.
final loginUri = Uri.parse(Config.apiURL, Config.loginAPI);
^</p>
</blockquote>
<pre><code>class Config {
static const String appName = "appName";
static const String apiURL = http://127.0.0.1:8000/;
static const String loginAPI = "api/dj-rest-auth/login/";
}
class AuthService {
final loginUri = Uri.parse(Config.apiURL, Config.loginAPI);
</code></pre>
<p>The error is showing for <code>Config.loginAPI</code>
How do I fix this error knowing that they are both strings, not int related to them.</p>
<p>What is the reason for it and how to fix it?</p>

74,341,308 | <p>I was trying to make a <em>single</em> function that takes in a container and implicitly have it convert to a <code>boost::iterator_range</code> as I thought that was it's purpose, but it seems that I'm missing something.</p>
<p>Here's an example of what I was thinking:</p>
<pre class="lang-cpp prettyprint-override"><code>#include <boost/range/iterator_range.hpp>
#include <vector>
template<typename IT>
void fn_x(boost::iterator_range<IT>) {
}
void fn_y() {
std::vector<int> a(64);
fn_x(boost::make_iterator_range(a.begin(), a.end())); // Works
fn_x(a); // Doesn't
}
</code></pre>
<p><a href="https://godbolt.org/z/3T6MM3141" rel="nofollow noreferrer"><kbd>Demo</kbd></a></p>
<p>So how would I get <code>fn_x</code> to accept both a container and a range object, in the same function?</p>
<p>Sorry, forgot to mention that I'm using c++14.</p>

74,341,368 | <p>I'm trying to find the index range (start index and end index, spaces are omitted, and with indexing starting at 1 for human readability.) of each word in a string. What I thought was the best approach was doing a list of lists where each nested list contains the word and a list of the start and end index. From a sample string, I get the following list:</p>
<pre><code>text = "i have a list of lists that contain a word and there indices my method works except with repeated words like of or a or the or it"
</code></pre>
<p>yields:</p>
<pre><code>boundaries_list=[['i', [1, 1]], ['have', [3, 6]], ['a', [4, 4]], ['list', [10, 13]], ['of', [15, 16]], ['lists', [18, 22]], ['that', [24, 27]], ['contain', [29, 35]], ['a', [4, 4]], ['word', [39, 42]], ['and', [44, 46]], ['there', [48, 52]], ['indices', [54, 60]], ['my', [62, 63]], ['method', [65, 70]], ['works', [72, 76]], ['except', [78, 83]], ['with', [85, 88]], ['repeated', [90, 97]], ['words', [99, 103]], ['like', [105, 108]], ['of', [15, 16]], ['or', [40, 41]], ['a', [4, 4]], ['or', [40, 41]], ['the', [48, 50]], ['or', [40, 41]], ['it', [86, 87]]]
</code></pre>
<p>This works, but its not very readable. Would sure be nice to compile it into a dictionary. Dictionaries work, except for when you have more than one of the same key. For me, that means that the first occurrence of a repeated word will be the ONLY occurrence of that word to be incorporated into the dictionary, thus excluding the index range of any other occurrences of that repeated word.</p>
<p>To get around this I tried using <code>defaultdict</code>,on a list of dictionaries but this only gave me the first word's index range repeated by n amount of word occurrences.</p>
<p>For Example:</p>
<pre><code>for one_d in boundaries_list:
nested_list_to_nested_dict = dict({one_d[0]:one_d[1] })
new_list.append(nested_list_to_nested_dict)
res = defaultdict(list)
for d in new_list:
for k, v in d.items():
res[k].append(v)
print(res)
>>> defaultdict(<class 'list'>, {'i': [[1, 1]], 'have': [[3, 6]], 'a': [[4, 4], [4, 4], [4, 4]], 'list': [[10, 13]], 'of': [[15, 16], [15, 16]], 'lists': [[18, 22]], 'that': [[24, 27]], 'contain': [[29, 35]], 'word': [[39, 42]], 'and': [[44, 46]], 'there': [[48, 52]], 'indices': [[54, 60]], 'my': [[62, 63]], 'method': [[65, 70]], 'works': [[72, 76]], 'except': [[78, 83]], 'with': [[85, 88]], 'repeated': [[90, 97]], 'words': [[99, 103]], 'like': [[105, 108]], 'or': [[40, 41], [40, 41], [40, 41]], 'the': [[48, 50]], 'it': [[86, 87]]})
</code></pre>
<p>Any help is much appreciated.</p>

</code></pre>
<p>in the manifest, under the "application" tab, also in the "activity" tag.</p>
<p>What wrong am I doing?</p>
<p>I also tried this:</p>
<pre><code> val intent = Intent(Intent.ACTION_VIEW)
intent.data = Uri.parse(MyActivity::class.java.name)
intent.addFlags( Intent.FLAG_ACTIVITY_LAUNCH_ADJACENT or FLAG_ACTIVITY_NEW_TASK)
startActivity(intent)
</code></pre>
<p>didn't work.</p>
<p>Another related question I want to ask is, is FLAG_ACTIVITY_NEW_TASK required? what if I don't want to create a new task?</p>

74,341,464 | <p>Is it possible to produce a million records a second via kafka? How many servers should it take? Currently i am sending 7000 messages a second from a kafka producer and struggling to exceed this</p>
<p>I've noticed several sources say kafka can send millions of messages a second</p>
<p>I've created a job that uses @Autowired kafkaTemplate and makes a while loop that sends a short text string "asdf" I've set up linger to 1000ms and seeing messages group in sets of 7000. The producer , consumer broker, zookeeper are on the same machine and the broker and zookeeper and a very simple docker image with default configuration</p>
<p>I am maxing out around 7000 requests a second</p>
<p>application.props</p>
<pre><code>spring.kafka.bootstrap-servers=PLAINTEXT://localhost:9092,PLAINTEXT://localhost:9093
host.name=localhost
</code></pre>
<p>Job to make calls</p>
<pre><code>@Async

int i = 0;
System.out.println("start");
long startTime = System.currentTimeMillis();
while(i <= 1000000){
String message = "Test Message sadg sad-";
kafkaTemplate.send(TOPIC, message + i);
i++;
}
long endTime = System.currentTimeMillis();
System.out.println((endTime - startTime));
System.out.println("done");

<p>For hardware I have a 10900k with 64gb ram
5ghz clock speed
970 Evo single nvme disk
10 core 20 thread</p>
<p>All requests are from the same machine to the same machine</p>
<p>Is there a better way to organize / optimize the code to make a massive number of requests?
Theories:</p>
<ol>
<li>Multiple Threads?</li>
<li>Changing configurations of servers such as tomcat configs (receiving or sending side)?</li>
<li>Not use the kafkaTemplate that is autowired or creating multiple?</li>
<li>Modify Hardware to have multiple disks?</li>
<li>Not use a job for the producer?</li>
<li>Anything else anyone can think of to help?</li>
</ol>

74,341,471 | <p>This question is come from <a href="https://stackoverflow.com/questions/74334249/how-to-sum-an-array-for-each-id-and-create-new-array-in-react">how-to-sum-an-array-for-each-id-and-create-new-array-in-react</a>,OP needs to sum data by id</p>
<pre><code>const data = [{"id": "One", "number": 100},
{"id": "One", "number": 150},
{"id": "One", "number": 200},
{"id": "Two", "number": 50},
{"id": "Two", "number": 100},
{"id": "Three", "number": 10},
{"id": "Three", "number": 90}]
</code></pre>
<p>In order to do it,I just use a traditional way(check with <code>if</code>) to do it with <code>reduce()</code></p>
<pre><code>let result2 = data.reduce((a, v) => {
let obj = a.find(i => i.id == v.id);
if (obj) {
obj.number += v.number;
} else {
a.push(v);
}
return a;
}, [])
console.log(result2);
</code></pre>
<p>And I found another answer is more elegant(one-liner):</p>
<pre><code>let result3 = data.reduce((acc, {id, number}) => ({...acc, [id]: {id, number: acc[id] ? acc[id].number + number: number}}), {});
console.log(Object.values(result3));
</code></pre>
<p>The question is that when I ran the two methods seperately,I can got the expected result(<a href="https://jsfiddle.net/Lxa9h60o/" rel="nofollow noreferrer">jsfiddle1</a> and <a href="https://jsfiddle.net/kuzy6p9j/" rel="nofollow noreferrer">jsfiddle2</a>)</p>
<p><a href="https://i.stack.imgur.com/UIcg2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/UIcg2.png" alt="enter image description here" /></a></p>
<p>However,if I ran them together,the seconds result(from <code>result3</code>) is not as expected(<a href="https://jsfiddle.net/gs0edu6b/" rel="nofollow noreferrer">jsfiddle 3</a>)
<a href="https://i.stack.imgur.com/dvkZu.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/dvkZu.png" alt="enter image description here" /></a></p>
<p>I do not know why this happen,can anyone help me to analysis this?</p>
<p>Also,I want to know if there are a more elegant one-liner solution to do it.</p>
<p>Thanks in advance!</p>

74,341,479 | <p>I have an app where users can login / sign out and the functionality stopped working recently when I added a new SceneDelegate view and moved over the code from the AppDelegate. I'm not sure why it is not working but I suspect it has to do with using the shared delegate in my signOut function.</p>
<p>Something strange is happening, when I tap the sign out button nothing happens. However, when I close the app and open it again, I will be signed out.</p>
<p>Here is the code on my home screen for the sign out button:</p>
<pre><code>@IBAction func signOutButtonTapped(_ sender: Any) {
KeychainWrapper.standard.removeObject(forKey: "accessToken")
KeychainWrapper.standard.removeObject(forKey: "userID")
// send user to splash page
let signInPage = self.storyboard?.instantiateViewController(withIdentifier: "splashController") as! splashViewController
let appDelegate = UIApplication.shared.delegate
appDelegate?.window??.rootViewController = signInPage
}
</code></pre>
<p>This is the code from my SceneDelegate.swift file:</p>
<pre><code>class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
guard let _ = (scene as? UIWindowScene) else { return }
let accessToken: String? = KeychainWrapper.standard.string(forKey: "accessToken")
// If access token exists, skip login page
if accessToken != nil {
if let windowScene = scene as? UIWindowScene {
self.window = UIWindow(windowScene: windowScene)
let mainStoryboard:UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let vc = mainStoryboard.instantiateViewController(withIdentifier: "homeTabController") as! TabBarController
self.window!.rootViewController = vc
}
}
}
}

74,341,489 | <p>I see this term a lot, 'symbol', and after searching on google I still can't find a definition that makes sense to me.</p>
<p>For example in the manual of <code>ar</code> command on Linux, it's said :</p>
<blockquote>
<p>ar creates an index to the symbols defined in relocatable object modules in the archive when you specify the modifier s.</p>
</blockquote>
<p>Are function declarations / variable declarations / defines / structure declarations etc, symbols ? Or is a symbol a term for .o files ?</p>
<p>In this context, what is a symbol exactly ? Act like I'm a complete beginner who knows nothing when you form your answer please !</p>

74,341,595 | <p>I'm currently trying to automate a game called Lyrics Training (<a href="https://www.lyricstraining.com/" rel="nofollow noreferrer">https://www.lyricstraining.com/</a>) and I am able to get the words that are from the button through some other code but I am currently struggling with clicking the "button" because it is for some reason classified as a in the HTML code. I was wondering whether there was a way or a function that would allow me to click it so I could finish the automation? Thanks!</p>
<p>So far I have this code that would work if the button was an actual button:</p>
<pre><code>let firstChoice = document.getElementsByClassName("slot s1")[0];
let secondChoice = document.getElementsByClassName("slot s2")[0];
let thirdChoice = document.getElementsByClassName("slot s3")[0];
let fourthChoice = document.getElementsByClassName("slot s4")[0];
// the click function isn't working
for(let i = 0; i < click_order.length; i++){
let word = click_order[i];
if(firstChoice.innerHTML === word){
firstChoice.click();
}else if(secondChoice.innerHTML === word){
secondChoice.click();
}else if(thirdChoice.innerHTML === word){
thirdChoice.click();
}else if(fourthChoice.innerHTML === word){
fourthChoice.click();
}
}
</code></pre>
<p>This is how the "buttons" look like in the HTML code of the website:</p>
<p><a href="https://i.stack.imgur.com/F0cdm.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/F0cdm.png" alt="DIV Buttons" /></a></p>
<p>Any help would be appreciated! Thanks!</p>

Need help with syntax on a macro prompt so the default can be to select all members</p>

<p>If I wanted to hard code a value I could use this as a slicer</p>

<p>What is the syntax for creating a macro prompt with a default of all members?
i.e. instead of ?Location?<br />
Something like this:</p>
<pre><code>#Prompt('Location', 'token', '[all]')#

<p>or maybe like</p>

74,341,618 | <p>I'm using Oracle and SQL Developer. I have downloaded HR schema and need to do some queries with it. Now I'm working with table <code>Employees</code>. As an user I need to see the list of employees with lowest salary in each department. I need to provide different solutions by means of plain SQL and one of analytic functions. About analytic functions, I have used <code>RANK()</code>:</p>
<pre><code>SELECT *
FROM
(SELECT
employee_id,
first_name,
department_id,
salary,
RANK() OVER (PARTITION BY department_id
ORDER BY salary) result
FROM
employees)
WHERE
result = 1
AND department_id IS NOT NULL;
</code></pre>
<p>The result seems correct:</p>
<p><a href="https://i.stack.imgur.com/1JhKf.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1JhKf.png" alt="Result" /></a></p>
<p>but when I try to use plain SQL I actually get all employees with their salaries.</p>
<p>Here is my attempt with <code>GROUP BY</code>:</p>
<pre><code>SELECT
department_id, MIN(salary) AS "Lowest salary"
FROM
employees
GROUP BY
department_id;
</code></pre>
<p>This code seems good, but I need to also get columns <code>first_name</code> and <code>employee_id</code>.</p>
<p>I tried to do something like this:</p>
<pre><code>SELECT
employee_id,
first_name,
department_id,
MIN(salary) result
FROM
employees
GROUP BY
employee_id,
first_name,
department_id;
</code></pre>
<p>and this:</p>
<pre><code>SELECT
employee_id,
first_name,
salary,
departments.department_id
FROM
employees
LEFT OUTER JOIN
departments ON (employees.department_id = departments.department_id)
WHERE
employees.salary = (SELECT MIN(salary)
FROM departments
WHERE department_id = employees.department_id)
</code></pre>
<p>These seem wrong. How can I change or modify my queries to get the same result as when I'm using <code>RANK()</code> by means of plain SQL (two solutions at least)?</p>

74,341,632 | <p>I have a module that redirects console outputs to the Tkinter window, which I found here on StackOverflow. It works perfectly, however, I realized I also need to save the console output to a file. But everything I tried either doesn't work, breaks the module, or nothing happens.</p>
<p>EDIT: I need to modify the following module so it also SAVES THE CONSOLE OUTPUT to the .txt document. BUT preserving it's current functionality</p>
<p>Here is the code for the module:</p>
<pre><code># Code derived from Bryan Olson's source posted in this related Usenet discussion:
# https://groups.google.com/d/msg/comp.lang.python/HWPhLhXKUos/TpFeWxEE9nsJ
# https://groups.google.com/d/msg/comp.lang.python/HWPhLhXKUos/eEHYAl4dH9YJ
#
# See the comments and doc string below.
#
# Here's a module to show stderr output from console-less Python
# apps, and stay out of the way otherwise. I plan to make a ASPN
# recipe of it, but I thought I'd run it by this group first.
#
# To use it, import the module. That's it. Upon import it will
# assign sys.stderr.
#
# In the normal case, your code is perfect so nothing ever gets
# written to stderr, and the module won't do much of anything.
# Upon the first write to stderr, if any, the module will launch a
# new process, and that process will show the stderr output in a
# window. The window will live until dismissed; I hate, hate, hate
# those vanishing-consoles-with-critical-information.
#
# The code shows some arguably-cool tricks. To fit everthing in
# one file, the module runs the Python interpreter on itself; it
# uses the "if __name__ == '__main__'" idiom to behave radically
# differently upon import versus direct execution. It uses tkinter
# for the window, but that's in a new process; it does not import
# tkinter into your application.
#
# To try it out, save it to a file -- I call it "errorwindow.py" -
# - and import it into some subsequently-incorrect code. For
# example:
#

# martineau - Modified to use subprocess.Popen instead of the os.popen
# which has been deprecated since Py 2.6. Changed so it
# redirects both stdout and stderr. Added numerous
# comments, and also inserted double quotes around paths
# in case they have embedded space characters in them, as
# they did on my Windows system.
#
# Recently updated it to work in both Python 2 and Python 3.
"""
Import this module into graphical Python apps to provide a
sys.stderr. No functions to call, just import it. It uses
only facilities in the Python standard distribution.
If nothing is ever written to stderr, then the module just
sits there and stays out of your face. Upon write to stderr,
it launches a new process, piping it error stream. The new
process throws up a window showing the error messages.

74,341,704 | <p>I'm trying to create an Excel spreadsheet and populate it with data from Word, but I can't get VBA to follow through. It launches Excel, but then it errors out.</p>
<p>If I try early binding, such as with this code from the Microsoft Documentation, I get a Run-time error '13': Type mismatch on the <code>Set xlApp</code> line.</p>
<pre><code>Sub test()
Dim xlApp As Excel.Application
Dim xlBook As Excel.Workbook
Dim xlSheet As Excel.Worksheet
Set xlApp = CreateObject("Excel.Application")
Set xlBook = xlApp.Workbooks.Add
Set xlSheet = xlBook.Worksheets(1)
End Sub
</code></pre>
<p>If I try late binding, I get a Run-time error '438': Object doesn't support this property or method on the <code>Set xlBook</code> line</p>

Dim xlApp As Object
Dim xlBook As Object
Dim xlSheet As Object
Set xlApp = CreateObject("Excel.Application")
Set xlBook = xlApp.Workbooks.Add
Set xlSheet = xlBook.Worksheets(1)
End Sub
</code></pre>
<p>Many people throughout StackOverflow use variations of this successfully. I can't figure out why it doesn't work for me. One user on StackOverflow reported that the problem only persisted on their Mac. If it is a platform problem, is there a way to fix it so it will work on my Mac?</p>

74,341,767 | <p>I'm using the following versions:</p>
<ul>
<li>"@apollo/gateway": "^2.1.3"</li>
<li>"@apollo/server": "^4.0.0"</li>
<li>"graphql": "^16.6.0"</li>
</ul>
<p>I can't get a handle on the <code>req</code> object to extract the headers and forward them. The <code>buildService</code> code works to add headers to requests to downstream services, but the <code>context</code> on ApolloServer is consistently empty. I tried sync and async, request instead of req. I even tried grabbing them directly from <code>context.req.headers</code>, but that's null.</p>
<p>Anyone have any idea on how to accomplish this?</p>
<pre class="lang-js prettyprint-override"><code>const gateway = new ApolloGateway({
supergraphSdl: new IntrospectAndCompose({
subgraphs: [
{ name: "persons", url: process.env.PERSON_SERVER_URL },
],
}),
buildService({ url }) {
return new RemoteGraphQLDataSource({
url,
willSendRequest: ({ request, context }) => {
console.log(JSON.stringify(context));
// TRYING TO INJECT AUTH HEADERS HERE
}
});
}
});
const app = express();
const httpServer = http.createServer(app);
const server = new ApolloServer({
gateway,
context: ({ req }) => {
console.log(JSON.stringify(req));
// req IS NULL
},
plugins: [
ApolloServerPluginLandingPageDisabled(),
ApolloServerPluginDrainHttpServer({ httpServer })
]
});
await server.start();
const graphqlRoute = "/graphql";
app.use(
graphqlRoute,
bodyParser.json(),
expressMiddleware(server),
);
await new Promise((resolve) => httpServer.listen(process.env.PORT, "0.0.0.0", resolve));
console.log(` Server ready at ${JSON.stringify(httpServer.address())}`);
</code></pre>
<p>For what it's worth, I asked <a href="https://community.apollographql.com/t/federation-forward-headers-to-subgraphs/4917" rel="nofollow noreferrer">here</a>, as well. This feels like it should be a simple flag (especially for federation) to forward the Authorization header.</p>

Can someone explain to me why the first one fails and the second (more explicit works)?
After my understanding, <code>x0</code> and <code>x1</code> are both <code>1x2</code> arrays and it should be possible to extend them to <code>5x2</code>.</p>
<pre><code>n_a = 5;
n_b = 2;
x0 = [1, 2];
x1 = [11, 22];
% c = unifrnd(x0, x1, [n_a, n_b])
% Error using unifrnd
% Size information is inconsistent.
% c = unifrnd(x0, x1, [n_a, 1]) % also fails
c = unifrnd(ones(n_a, n_b) .* x0, ones(n_a, n_b) .* x1, [n_a, n_b])
% works

74,341,855 | <p>I'm trying to think of a way to make functions that determine the winner of an election by most votes, as well as a function that determines a winner-takes-all rule.</p>
<p>My code is as follows:</p>
<pre><code>_base_dict = {}
def add_state(name: str, votes: dict[str, int]) -> None:
global _base_dict
for name, votes in _base_dict.items():
_base_dict[name] += votes
def winner(college: dict[str, int]) -> str:
global _base_dict
rv = None
bigger_percentage = 0
for state, total_votes in college.items():
majority = total_votes // 2
for name, votes in _base_dict.items():
if votes[state] > majority:
percentage = votes[state] / float(total_votes)
if percentage > bigger_percentage:
bigger_percentage = percentage
rv = name
elif percentage == bigger_percentage:
rv = None
if rv is None:
return "No Winner"
return rv
def clear() -> None:
global _base_dict
_base_dict.clear()
_base_dict.update(_base_dict)
</code></pre>
<p>and on a test file, I am running the functions through this:</p>
<pre><code>import elections
college = {'Virginia': 13,
'Ohio': 18,
'Minnesota': 10,
'Alabama': 9,
'Maine': 4
}
print(elections.winner({}))
elections.add_state('Virginia', {
'Turing': 15,
'Lovelace': 20,
'Dijkstra': 10
})
elections.add_state('Ohio', {
'Turing': 1,
'Dijkstra': 15
})
elections.add_state('Alabama', {
'Turing': 10,
'Lovelace': 20,
'Dijkstra': 8
})
print(elections.winner(college))
elections.add_state('Minnesota', {
'Lovelace': 10,
'Dijkstra': 30,
})
elections.add_state('Florida', {
'Turing': 10,
'Lovelace': 30,
'Dijkstra': 15
})
print(elections.winner(college))
elections.clear()
elections.add_state('Maine', {
'Turing': 2,
'Dijkstra': 1,
'Lovelace': 5
})
print(elections.winner(college))
</code></pre>
<p>My desired output is:</p>
<pre><code>No Winner
Lovelace
Dijkstra
Lovelace
</code></pre>
<p>but I keep getting:</p>
<pre><code>No Winner
No Winner
No Winner
No Winner
</code></pre>
<p>I do not know what I am doing wrong. Any help is appreciated.
Edit: I prefer to use logic to solve this issue, though imports are also appreciated.</p>

74,341,887 | <p>I am trying to get a hold over understanding Applicative functors currently. And my understanding is falling short somewhere but I cannot pinpoint where.
Source from where I am trying to build an understanding <a href="https://www.cis.upenn.edu/%7Ecis1940/spring13/lectures.html" rel="nofollow noreferrer">CIS 194 UPenn</a> - <a href="https://www.cis.upenn.edu/%7Ecis1940/spring13/hw/10-applicative.pdf" rel="nofollow noreferrer">Homework 10</a></p>
<p>I am working with a custom data type and its Applicative instance which are as follows :</p>
<pre><code>-- A parser for a value of type a is a function which takes a String
-- represnting the input to be parsed, and succeeds or fails; if it
-- succeeds, it returns the parsed value along with the remainder of
-- the input.
newtype Parser a = Parser { runParser :: String -> Maybe (a, String) }
instance Functor Parser where
fmap :: (a -> b) -> Parser a -> Parser b
fmap fn parserA = Parser (fmap (first fn) . parseAFunc)
where parseAFunc = runParser parserA
appliedFunc p1 p2 str = case runParser p1 str of
Nothing -> Nothing
Just (f, str2) -> case runParser p2 str2 of
Nothing -> Nothing
Just (x, str3) -> Just (f x, str3)
instance Applicative Parser where
pure a = Parser (\s -> Just (a, s))
p1 <*> p2 = Parser (appliedFunc p1 p2)
-- For example, 'satisfy' takes a predicate on Char, and constructs a
-- parser which succeeds only if it sees a Char that satisfies the
-- predicate (which it then returns). If it encounters a Char that
-- does not satisfy the predicate (or an empty input), it fails.
satisfy :: (Char -> Bool) -> Parser Char
satisfy p = Parser f
where
f [] = Nothing -- fail on the empty input
f (x:xs) -- check if x satisfies the predicate
-- if so, return x along with the remainder
-- of the input (that is, xs)
| p x = Just (x, xs)
| otherwise = Nothing -- otherwise, fail
-- Using satisfy, we can define the parser 'char c' which expects to
-- see exactly the character c, and fails otherwise.
char :: Char -> Parser Char
char c = satisfy (== c)
-- Below is a parser for positive Ints which parses
-- the prefix of contiguous digits in a given String
-- as an Int
posUse :: Parser Int
posUse = Parser f
where
f xs
| null ns = Nothing
| otherwise = Just (read ns, rest)
where (ns, rest) = span isDigit xs
-- Below function takes a function and a pair and returns a pair
-- with the function applied to the first element of pair
first :: (a -> b) -> (a, c) -> (b, c)
first fn (x, y) = (fn x, y)
</code></pre>
<p>Using all the above setup, I am trying to construct some more complicated Parsers using simple Parsers defined above. So fmap has type <code>fmap :: Functor f => (a -> b) -> f a -> f b</code>. And as per my understanding currently, Applicative allows us to extend <code>fmap</code> to functions that take n-ary functions and n Functor parameters and return the resultant functor.</p>
<p><code>fmap</code> can be defined in terms of <code>pure</code> and <code><*></code> as :</p>
<pre><code>fmap1 :: Applicative f => (a -> b) -> f a -> f b
fmap1 f x = pure f <*> x
</code></pre>
<p>I understand why the above will work given that the implementations of <code>pure</code> and <code><*></code> are appropriate since the types nicely line up.</p>
<p>Extending this to <code>fmap2</code> aka <code>liftA2</code> :</p>
<pre><code>fmap2 :: Applicative f => (a -> b -> c) -> f a -> f b -> f c
fmap2 f x y = pure f <*> x <*> y
</code></pre>
<p>My understanding of why the above works is as follows :
<code>pure g</code> will have type <code>f (a -> b -> c)</code> And so therefore <code>pure g <*> x</code> will have type <code>f (b -> c)</code> since functions are curried. Then this type combined with the type type of y (<code>f b</code>) using <code><*></code> will finally give us the type of the result which is <code>f c</code> which is what we needed the type <code>fmap2</code> to be.</p>
<p>This understanding did not break down when I tried to construct a Parser out of 2 simple Parsers as follows :</p>
<pre><code>-- This Parser expects to see the characters ’a’ and ’b’ and returns them
-- as a pair.
abParser = liftA2 (\c1 c2 -> (c2 c1)) (char 'a') (char 'b')
</code></pre>
<p>The above works as expected.</p>
<p>But when I try to make the parser <code>intPair</code> which reads two integer values separated by a space and returns the integer values in a list using <code>liftA3</code> my understanding of lift is not working since I expect the following to work but the linter complains :</p>
<pre><code>intPair :: Parser [Int]
intPair = liftA3 (\x y z -> [z x]) posUse (char ' ') posUse
</code></pre>
<p>The above does not compile as the last argument needs to have the type <code>Parser (Int -> a)</code> (according to type inference) but I have passed <code>posUse</code> which has the type <code>Parser Int</code>.</p>
<p>TL;DR :
Sorry for the long description. If anyone does not want to go through it all (expecially the custom data type and its Applicative and Functor instance) -- please let me know if my understanding of why <code>fmap2</code> aka <code>liftA2</code> works is correct and how does that understanding extend to <code>liftA3</code> ?
The definition of <code>liftA3</code> seems to be something different than just an extension of the definition of <code>liftA2</code> using <code><*></code> and <code>pure</code>.</p>
<p>Edit 1 :
As stated above, the below line was being complained about by the linter</p>
<pre><code>intPair :: Parser [Int]
intPair = liftA3 (\x y z -> [z x]) posUse (char ' ') posUse
</code></pre>
<p>The linter expected the type for the last argument to be <code>Parser (Int -> a)</code>.
But after I defined an explicit function instead of passing a lambda, it worked as I expected to work.</p>
<pre><code>fnn :: Int -> Char -> Int -> [Int]
fnn arg1 arg2 arg3 = [arg1, arg3]
intPair = liftA3 fnn posUse (char ' ') posUse
</code></pre>
<p>It works as I expected.</p>

74,341,905 | <p>For this project I am working on, I have a list of strings of equal length (so the length may vary), and I only want the strings whose substrings can be found in a string that I have specified.</p>
<p>Will elaborate further, but the following is the expected result.</p>
<pre><code># list of strings
["aa", "ct", "ab", "ac", "bd", "ra", "db", "pq", "cb"]
# a subset of this list is not included in a new list because they do not contain a/b/c/d
# -> this list of strings
["aa", "ab", "ac", "bd", "db", "cb"]
# in other words, "ct", "ra", "pq" are excluded
</code></pre>
<p>However, when I print the new list of valid strings as shown below, every string except for "pq" is included. It seems to yield a similar result as using the any() function, which would be great if only it does what I want it to.</p>
<pre><code>list_of_strings = ["aa", "ct", "ab", "ac", "bd", "ra", "db", "pq", "cb"]
def isValidString(seq):
for substring in seq:
if substring in "abcd":
return True
valid_strings = []
for sequence in list_of_strings:
if isValidString(sequence):
valid_strings.append(sequence)
print(valid_strings)
# Output : ['aa', 'ct', 'ab', 'ac', 'bd', 'ra', 'db', 'cb']

The only problem is that now I have this unused "i" variable. Is there a way to write it without needing that variable, or should I not worry about it too much?</p>

74,342,135 | <p>can anyone help me how to convert this into loops :) hi newbie here in javaScript:) the output of this is a input form, i want all the value that typed into the form to be appear instantly by using keyup event thanks in advance :)</p>
<pre><code>let textarea = document.querySelectorAll('span')
let bns = document.querySelector('#bns');
let id = document.querySelector('#id');
let img = document.querySelector('#img');
let lg = document.querySelector('#lg');
textarea.forEach(function (item, index) {
item.classList.add('t'+ `${index}`)
//console.log(item)
})
let input = addEventListener('keyup', function(){
let strbns = bns.value;
let strid = id.value;
let strimg = img.value;
let strblg = lg.value;
document.querySelector('.t0').innerText = strbns
document.querySelector('.t1').innerText = strid
document.querySelector('.t2').innerText = strimg
document.querySelector('.t3').innerText = strblg
});

<p>output
<a href="https://i.stack.imgur.com/rmpGV.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/rmpGV.jpg" alt="enter image description here" /></a></p>
<p>i create variables to each input field and used the keyup event to print the out put to individual span. yes it works but its so repetitive and i thinks it is much better if it's convert it into for loops but i dont know how</p>

74,342,196 | <p>I am new to Gatling and Scala , I am trying to run the Gatling test example specified in the beginning parts of this video: <a href="https://www.youtube.com/watch?v=To7LJiK87Us" rel="nofollow noreferrer">https://www.youtube.com/watch?v=To7LJiK87Us</a>, but using Gradle wrapper.
I created a gradle project in IntelliJ idea and the build.gradle file is below</p>
<pre><code>buildscript {
repositories {
maven {
url '<url>'
credentials {
<><>
}
}
}
dependencies {
classpath "gradle.plugin.io.gatling.gradle:gatling-gradle-plugin:3.8.4"
}
}
apply plugin: "io.gatling.gradle"
apply plugin: 'scala'
repositories {
maven {
url '<>'
credentials {
<><>
}
}
mavenCentral()
}
dependencies {
implementation 'org.scala-lang:scala-library:2.12.4'
gatling 'org.scala-lang:scala-library:2.12.4'
gatling 'au.com.bytecode:opencsv:2.4'
gatling group: 'org.scalaj', name: 'scalaj-http_2.12', version: '2.3.0'
gatling group: 'org.json4s', name: 'json4s-native_2.12', version: '3.5.3'
}
compileGatlingScala {
scalaCompileOptions.additionalParameters = ["-feature"]
}
gatling {
simulations = {
// Enable ALL perf testing, regardless of current pass/fail state
include "**/simulation/*Simulation*.scala"
}
}
sourceSets.gatling.resources.srcDir('conf')
gatling {
logLevel = 'WARN' // logback root level
logHttp = 'ALL'
}
</code></pre>
<p>Note: I have a few extra dependencies here like 'opencsv' that I will be needing later for the actual performance testing.</p>
<p>And my LoadSimulation script is as below</p>
<pre><code>class LoadSimulation extends Simulation {
val scn = scenario("JSON")
.exec(
http("GET")
.get("http://jsonplaceholder.typicode.com/comments")
)
setUp(
scn.inject(atOnceUsers(1))
)
}
</code></pre>
<p>When I try to run the performance test using gradlew, it says "build successful', but I don't see a result in the reports folder under /build</p>
<pre><code>>gradlew gatlingRun-LoadSimulation
BUILD SUCCESSFUL in 1s
3 actionable tasks: 1 executed, 2 up-to-date
</code></pre>
<p>Could anyone please tell me what I am doing wrong? Is this not how I should be running it?</p>
<p><strong>EDIT</strong>
Updated to below dependencies as per answers below, still the same result, nothing in the /build/reports/gatling folder.</p>
<pre><code>dependencies {
implementation 'org.scala-lang:scala-library:2.13'
gatling 'org.scala-lang:scala-library:2.13'
gatling 'au.com.bytecode:opencsv:2.4'
gatling group: 'org.scalaj', name: 'scalaj-http_2.13', version: '2.4.2'
gatling group: 'org.json4s', name: 'json4s-native_2.13', version: '3.6.7'
}

74,342,249 | <p>I have encountered several problems relating to the arrow function and, after a simple google search or two, I fixed them.</p>
<p>Then I encountered this:</p>
<pre><code>this.projectiles = this.projectiles.filter(projectile =>projectile.markedForDeletion);
</code></pre>
<p>I got an error saying that "'arrow function syntax (=>)' is only available in ES6 which is not supported by this environment."
I did several google searches and still don't know how to fix it.</p>
<p>I tried to repace the arrow with this:</p>
<pre><code>this.projectiles = this.projectiles.filter(function(projectile) {});
</code></pre>
<p>But I need to input the</p>
<pre><code>!projectile.markedForDeletion
</code></pre>
<p>into the code, but I don't know where or how.</p>
<p>Can someone please help?</p>

74,342,265 | <p>I'm working on project where I have an an accordion with checkboxes. When the checkboxes have a value of true they go to my <code>trueItems</code> array. I have an array <code>filter</code> that I need to register the change of value to true when the button with <code>handleSubmit</code> is clicked. The issue that I'm having is with the final part. I'm struggling to figure out how to get the variables in <code>filter</code> to change to true. I've tried: <code>x => {setFilter({...filter, x,}), true</code> but that didn't do anything, and I've tried <code>x => {setFilter({...filter, x: true,}), </code>
but that didn't work either. I would really appreciate any help or advice on how to do this. Thank you!</p>
<pre><code>function handleSubmit () {
for (var items of trueItems){
for (var x in filter){
if(x === items.name) {
x => {
setFilter({
...filter,
x,
})
}}}}}
</code></pre>
<p>where filter is:</p>
<pre><code> const [filter, setFilter] = useState({
pescatarian: false,
vegan: false,
vegetarian: false,
...
});
</code></pre>
<p>and trueItems is:</p>
<pre><code>[{"name": " pescatarian", "value": true}...]

<pre><code>Got a `TypeError` when calling `Post.objects.create()`. This may be because you have a writable field on the serializer class that is not a valid argument to `Post.objects.create()`. You may need to make the field read-only, or override the PostSerializer.create() method to handle this correctly.
Original exception was:

74,342,476 | <p>My team was in trouble in push alarm with FCM token in flutter (especially ios),<br />
So we decided to push alarm to each user with topics.</p>
<p>I know that "One app instance can be subscribed to no more than 2000 topics." in
<a href="https://firebase.google.com/docs/cloud-messaging/android/topic-messaging" rel="nofollow noreferrer">Firebase Document</a></p>
<p>But i confused about "One app instance".
Is that mean each android or ios application user can subscribe 2000 topics?
or Each FCM Server can create up to 2000 topics?</p>
<p>I wonder about One app instance's meaning in "One app instance can be subscribed to no more than 2000 topics"</p>

<pre><code>public class PostRequest {
Context context;
MyApplication application;
public String post(){
KeyStore trustStore = KeyStore.getInstance("BKS");
InputStream trustStoreStream = application.getResources().openRawResource(R.raw.certificate);
}
}
</code></pre>
<p>I am getting the error, <code>Attempt to invoke virtual method getResources() on a null object reference. </code></p>
<p>I created a variable <code>Context context</code> to and used that <code>context.getResources().openRawResource(R.raw.certificate);</code> but still with no success. This is a library so I don't have MainActivity or any activity classes.</p>

74,342,550 | <p>I have several images that are 50x50, fit into a row of 6 columns (ie, 6 images to a row). However, on rendering each image is seemingly on its own individual row, so it looks like the images are stacked on top of another, instead of on a single row.</p>
<p>The code is simple:</p>
<pre><code><div class="container">
<div class="row">
<div class="col-xs-2">
<img style="height:50px;width:50px" src="https://www.seiu1000.org/sites/main/files/main-images/camera_lense_0.jpeg" />
</div>
<div class="col-xs-2">
<img style="height:50px;width:50px" src="https://www.seiu1000.org/sites/main/files/main-images/camera_lense_0.jpeg" />
</div>
<div class="col-xs-2">
<img style="height:50px;width:50px" src="https://www.seiu1000.org/sites/main/files/main-images/camera_lense_0.jpeg" />
</div>
<div class="col-xs-2">
<img style="height:50px;width:50px" src="https://www.seiu1000.org/sites/main/files/main-images/camera_lense_0.jpeg" />
</div>
<div class="col-xs-2">
<img style="height:50px;width:50px" src="https://www.seiu1000.org/sites/main/files/main-images/camera_lense_0.jpeg"/>
</div>
<div class="col-xs-2">
<img style="height:50px;width:50px" src="https://www.seiu1000.org/sites/main/files/main-images/camera_lense_0.jpeg" />
</div>
</div>
</div>
</code></pre>
<p>See live example: <a href="https://jsfiddle.net/sedf765k/" rel="nofollow noreferrer">https://jsfiddle.net/sedf765k/</a></p>
<p>The problem is confusing because there are 6 <code>col-xs-2</code> which add up to <code>12</code>, so they should perfectly be aligned in the row. Why is this happening, and how can I properly line them up in the row?</p>
<p><strong>Additionally</strong>, because the images are smaller than the row itself in most cases, is there a way to decrease the empty space between them and float them to the left nicely, so that it looks like each image is next to each other, like people standing in a line?</p>

74,342,624 | <p>It worked on .NET 6, but now when I migrated my .net maui project to .net 7 the problem starts occurring: I have MediaPicker placed to one xaml page of my project in order to capture a picture and store it at the app data directory. I can run Android emulator and get permission for camera, but it stopped working for storage. I deleted and re-created Android emulator device, I tried different Android versions like API 29, 33, but nothing works. I used to pop up Android permission dialog window automatically when it executes <code>CapturePhotoAsync</code>, now it does not, and even when explicitly request the permission it still does not show dialog window and retuns <code>Denied</code> immidiatelly</p>
<pre><code>// got PermissionStatus.Denied, no dialog window requesting permission pops up
PermissionStatus status = await Permissions.RequestAsync<Permissions.StorageWrite>();
</code></pre>
<p>If I ignore it and tries to store the picture it predictably raises the exception <code>Microsoft.Maui.ApplicationModel.PermissionException: 'StorageWrite permission was not granted: Denied'</code></p>
<p>Anyone can suggest what could be wrong and what can I try to get it resolved</p>
<p><strong>UPDATE</strong>: created min. project and uploaded it to the github: github.com/YMichurin/mauiStoragePermissions</p>

74,342,697 | <p><code>while [List]: </code> vs <code>while [List] is True</code>? What is the different?</p>
<p>For example I am doing this problem (heap and priority queues) <a href="https://leetcode.com/problems/find-k-pairs-with-smallest-sums/" rel="nofollow noreferrer">https://leetcode.com/problems/find-k-pairs-with-smallest-sums/</a> and here is a sample solution that I retrieved. I do not understand this line <code>while len(res) < k and heap:</code>. Why do I need <code>while heap:</code>? and Also when I tried <code>while ... heap is True</code>, the code no longer works.</p>
<pre><code>class Solution:
"""Returns List[List[int]]"""
def kSmallestPairs(self, nums1, nums2, k):
# nums1 and nums2 are both sorted list
res = []
if not nums1 or not nums2 or not k:
return res
heap = []
visited = set()
heapq.heappush(heap, (nums1[0] + nums2[0], 0, 0))
visited.add((0, 0))
while len(res) < k and heap:
_, i, j = heapq.heappop(heap)
res.append([nums1[i], nums2[j]])
if i + 1 < len(nums1) and (i + 1, j) not in visited:
heapq.heappush(heap, (nums1[i + 1] + nums2[j], i + 1, j))
visited.add((i + 1, j))
if j + 1 < len(nums2) and (i, j + 1) not in visited:
heapq.heappush(heap, (nums1[i] + nums2[j + 1], i, j + 1))
