<p><a href="https://pl.kotl.in/UelOEOTdS?theme=darcula" rel="nofollow noreferrer">this snippet</a> will print <code>[4, 4, 4, 4, 4]</code></p>

<p>If I used <code>4; 6; 7; 9; 10</code>, the list will print</p>
<pre><code>[10, 10, 10, 10, 10]

<p>if anyone care to help, <a href="https://pl.kotl.in/2f47xTqsJ?theme=darcula" rel="nofollow noreferrer">this snippet</a> below it just doesn't work</p>
<pre><code>fun main() {

74,163,952 | <p>I'm using UIKit <strong>not SwiftUI</strong>. I found solutions which all in SwiftUI but not solved my problem.</p>
<p>I have a @Published object like:
<code>@Published var searchText = ""</code></p>
<p>I'm using that @Published object for search functionality like in following function. Also, I'm trying to reach that function outside of corresponding class which is <code>final class MainViewModel</code></p>
<pre><code>final class MainViewModel {
@Published var searchText = ""
//subscribes to the searchText 'Publisher'
func searchTextManipulation(searchText: String) {
$searchText
.debounce(for: .seconds(1.0), scheduler: RunLoop.main)
.removeDuplicates()
.sink { [weak self] (text) in //(text) is always empty string ""
...
</code></pre>
<p>I want to use that function parameter <code>searchText: String</code> as <code>$searchText</code> to search with text come from another screen something like:</p>
<pre><code>final class MainViewController {
let viewModel = MainViewModel()
@Published var searchText = ""
override func viewDidLoad() {
viewModel.searchTextManipulation($searchText: searchText) //but it's not possible.
}
}
</code></pre>
<p>Can you show me a workaround for solving that crucial part?</p>

74,163,958 | <p>In R, I'm trying to average a subset of a column based on selecting a certain value (ID) in another column. Consider the example of choosing an ID among 100 IDs, perhaps the ID number being 5. Then, I want to average a subset of values in another column that corresponds to the ID number that is 5. Then, I want to do the same thing for the rest of the IDs. What should this function be?</p>

74,163,982 | <p>I have a rule using files named with a series of numbers from <code>01</code>, <code>02</code>, <code>03</code> ... until <code>12</code> in their file name, and I would need to format them in <code>1</code>, <code>2</code>, <code>3</code>... <code>12</code> for the next step in the analysis.</p>
<p>I am sure there is a way to do this with either f-strings or <code>.format()</code>, but I am not sure how to do it within one rule where I also specify the number series with a list.</p>
<p>How do I get there?</p>
<p>A minimal example (not working):</p>
<pre><code>numbers = ["01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", "12"]
starting_folder = "project/temp"
rule rename_files:
input: f"{starting_folder}/file.{{numbers}}.ext"
output: f"{starting_folder}/file.{{{numbers}}:01d}_new.ext"
shell: "ln -s {input} {output}"
</code></pre>
<p>E.g. I would like to get <code>project/temp/file.1_new.ext</code> as the output file path.</p>

<p>Previously, I've tried setting <code>overflow: hidden;</code> but in some browsers/os it didn't let JavaScript scroll. I've tried setting <code>overflow: auto;</code> and hiding the scrollbar and then in JavaScript listening for <code>wheel</code> events and calling <code>preventDefault()</code> but that did nothing.

74,164,038 | <p>So here's something I don't understand : Every single time you include something in c, you have to do <code>#include "dir/subdir/file.h"</code>. Since the <code>.c</code> file is in the <strong>exact</strong> same place, why do I also have to do <code>gcc main.c dir/subdir/file.c -o main</code> ?</p>
<p>It doesn't seem to make sense, every single other language I've used (arguably not that many, but still, several) was able to make sense of imports on its own. Am I missing something ? Is there a way to tell gcc to "just find them yourself" ?</p>

74,164,048 | <p>I'm currently trying to set up a webdriver, and I just realised the reason it's not working is because I can't get the path to work. Currently, I'm trying basic code:</p>
<pre><code>file = "D:\\"
if os.path.exists(file):
print(True)
else:
print(False)
</code></pre>
<p>And the answer is "False". Now, I do have a D:/ drive on my computer.</p>
<p>I tried r"D:", "D:\", "D:/", basically everything I could find in other articles. Has anybody else ever encountered this?</p>

74,164,066 | <p>I have a string that starts "{{ABC..." and which will also contain a closing brace pair. The problem is that it may also contain nested open/close brace pairs, and may contain further brace pairs after the matching closing pair. E.g. this is possible:</p>
<pre><code> {{ABC foo bar {{baz}} {{fred}} foo2}} other text {{other brace pair}}
</code></pre>
<p>In this case I would want the string up to "foo2}}. I can see how to do this by writing my own recursive function call, but is there a way to match this in a single pass?</p>

74,164,086 | <p>Good morning friends, good ... what happens is this: I tried to make a logic so that the setLoaded changes the value of my progress bar, and when the value of it reaches 100, it shows the Modal. But nothing is happening. I wanted when I pressed the play button my ProgressBar to start loading its value, and when I clicked the pause button the value of it would stop at the value it was. Will someone help me please? I've worked very hard, I'm getting discouraged
I want activate this through Play button (touchable opacity)</p>

<p>Since, I want to use Security annotations to secure my end points I have set the security configuration as following:</p>
<pre><code>@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(
prePostEnabled = true,
securedEnabled = true,
jsr250Enabled = true)
public class SecurityConfig {
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http
.cors()
.and().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and().authorizeRequests()
.anyRequest().permitAll()
.and().oauth2ResourceServer().jwt();
http.csrf().disable();
return http.build();
}
</code></pre>
<p>Finally, in order to protect my endpoints I have used annotations like following:</p>
<pre><code>@RestController
public class TestControllers {
// Public endpoint
@GetMapping("/welcome")
public ResponseEntity<String> welcome() {
return ResponseEntity.status(HttpStatus.OK).body("Welcome to the unprotected endpoint");
}
// @RolesAllowed("clientApp1User")
// @Secured("clientApp1User")
@PreAuthorize("hasAuthority('clientApp1User')")
@GetMapping("/clientApp1User")
public ResponseEntity<String> clientApp1User() {
return ResponseEntity.status(HttpStatus.OK).body("clientApp1User protected endpoint sends its regards");
}
@PreAuthorize("hasAuthority('SCOPE_email')")
@GetMapping("/testScope")
public ResponseEntity<String> testScope() {
return ResponseEntity.status(HttpStatus.OK).body("testScope protected endpoint sends its regards");
}
}
</code></pre>
<p>The problem that I face is that the endpoint, which is protected with @RolesAllowed("clientApp1User") or @Secured("clientApp1User") or @PreAuthorize("hasAuthority('clientApp1User')") returns 403 forbidden, when it's called with a valid access token.</p>
<p>On the other hand endpoints with annotations like @PreAuthorize("hasAuthority('SCOPE_email')") or @PreAuthorize("hasAuthority('SCOPE_profile')") return 200 Ok.</p>
<p>I believe spring boot can not accurately parse the JWT token and only excepts values in scope claim with the prefix <SCOPE_> and as an authority.</p>
<p>Can any one help me to fix the problem and use the <strong>RolesAllowed/Secured/PreAuthorize</strong> annotations to secure the endpoint with <strong>declared roles in realm_access and resource_access claims</strong>?</p>

<p>C failing makes sense and has a good error message. B feels like it should work, Foo and all it's contents should be complete and defined at that point in the file. Basically my question is: do I report a clang bug that B should work, or a feature request for a better error message? If Foo is truly not complete by virtue of being a member of an incomplete type, then I should think the error message should be similar to that of C.</p>
<p><em>Edit:</em></p>
<p>I just upgraded clang to the bleeding edge (<code>16.0.0-++20221021052626+7dd2f4bc009d-1~exp1~20221021172738.418</code>) and got the same result.</p>

74,164,199 | <p>I'm having some trouble figuring out a problem in my code. Basically, I have a contract that represents games using structs. I store some details there like the gameId, required buyin to play, etc. But I also want to store player addresses that interact with that specific game: (in an array in the game struct, preferably).</p>
<p>I try to append them to the array on initialization but that doesn't work - I assume due to the static length of the array. I've read online about incrementing the length of the players array as they are not dynamic, but honestly I'm not sure how to implement that in this case.</p>
<p>Here is my code for the Game struct:</p>
<pre><code>struct Game {
address host; // Establishes host function access
uint gameId; // Allows different games to be played concurrently
uint buyinRequirement; // To establish minimum buyin amount for a game
uint etherWithdrawalReqs; // Tracks # of ether in total from requests. If >/< than contract balance, throws error
uint gamePot; // Tracks how much ether is in the game's pot
uint8 tableWithdrawalReqs; // Tracks how many players have requested a withdrawal
uint8 playerCount; // Tracks # of of players in a game
uint8 verifiedWithdrawalReqs; // Tracks # of verifs that withdrawal requests are valid
bool endedBuyin; // Host function to end buyin stage
address[] playerList; // Stores player addresses
}
</code></pre>
<p>Here is my attempt to initialize the struct:</p>
<pre><code>function initializeGame(string memory name, uint buyinReq) public payable {
idToGame[gameNumber] = Game(msg.sender, gameNumber, buyinReq, 0, 0, 0, 0, 0, false, playerList.push(msg.sender));
games.push(idToGame[gameNumber]);
}
</code></pre>
<p>This is the error I get:</p>
<pre><code> DeclarationError: Undeclared identifier.
--> contracts/YourContract.sol:104:93:
|
104 | idToGame[gameNumber] = Game(msg.sender, gameNumber, buyinReq, 0, 0, 0, 0, 0, false, playerList.push(msg.sender));
| ^^^^^^^^^^
Error HH600: Compilation failed
</code></pre>
<p>Ultimately, I just need to track addresses tied to a specific game so I can render those addresses to the front end with some other information. If there is an easier way to do this and I'm just overlooking something due to tunnel vision, I'm all ears for alternative solutions.</p>
<h2>Edit</h2>
<p>Shout out to 7Ony for the response!</p>
<p>Here is my code now:</p>
<pre><code>function initializeGame(string memory name, uint buyinReq) public payable isNotInGame {
require(initFee == .001 ether, "In order to prevent spam games that never resolve, each game initialization will cost ether.");
playerInfo[msg.sender] = Player(name, gameNumber, 0, 0, false, false, false, false, true);
address[] memory add;
idToGame[gameNumber] = Game(msg.sender, gameNumber, buyinReq, 0, 0, 0, 0, 0, false, true, add);
idToGame[gameNumber].playerList.push(msg.sender);
games.push(idToGame[gameNumber]);
incGameNumber();
addFeesPending();
}
</code></pre>
<p>There are no errors when I compile this code, however when I attempt to render the Game to my front end via ethersjs, it's like the array was never created:</p>
<pre><code>0x59D101AD9DdeA84C0e11DA137000Dd91A0b20c79,1,1000000000000000000,0,1000000000000000000,0,1,0,false,true (cuts off the playerList array, which should be the very last element)
</code></pre>
<p>Console-logged output:</p>
<p><a href="https://i.stack.imgur.com/TS1J2.png" rel="nofollow noreferrer">Console-logged image of Game struct</a></p>
<p>Am I doing something wrong here?</p>
<h2>Edit 2</h2>
<p>Alright, here is my getter function:</p>
<pre><code>function getPlayers(uint inputId) external returns (address[] memory playerList) {
playerList = games[inputId].playerList;
}
</code></pre>
<p>As a reminder, playerList is the array I have located inside the Game struct and games holds those structs. As of now, this is what it looks like getPlayers is returning:</p>
<pre><code> {"type":2,"chainId":31337,"nonce":32,"maxPriorityFeePerGas":{"type":"BigNumber","hex":"0x59682f00"},"maxFeePerGas":{"type":"BigNumber","hex":"0x59b61d36"},"gasPrice":null,"gasLimit":{"type":"BigNumber","hex":"0x6f8c"},"to":"0x9fE46736679d2D9a65F0992F2272dE9f3c7fa6e0","value":{"type":"BigNumber","hex":"0x00"},"data":"0x460e20490000000000000000000000000000000000000000000000000000000000000000","accessList":[],"hash":"0x221b93ed95fdc65e07a340a8e099e0b8e3600a0b34538825462d7dbbff400a89","v":0,"r":"0xbb258e1b11ed29ea57b12c6336f73572f4bf7c7ad13415dc6af19895ff628b54","s":"0x0e09991ebb19abdc6359f847b35e74d3358d8d43460f9d5b55289d77f2745a5d","from":"0x59D101AD9DdeA84C0e11DA137000Dd91A0b20c79","confirmations":0}
</code></pre>
<p>In this instance, I had it so there should be both the account address of <code>0x59D101AD9DdeA84C0e11DA137000Dd91A0b20c79</code> and <code>0xd8098C8D6D474a8C7aA3eFa076C1695DcBc6DD4F</code> in the playerList, but neither show up.</p>
<p>Unless I am not seeing something that you are, the getter I retrofitted over from the previous question does not seem to be outputting what I expected it to.</p>

74,164,209 | <p>How to get RedisInsight working with <code>PersistentVolumeClaim</code>s?</p>
<p>I installed RedisInsight following the <a href="https://docs.redis.com/latest/ri/installing/install-k8s/" rel="nofollow noreferrer">docs</a> and the Pod starts normally and is available via the created Service, if the <code>deployment.yaml</code> uses <code>emptyDir</code>. Therefore, my question differs from <a href="https://stackoverflow.com/questions/62714925/redisinsights-with-persistent-volume-in-kubernetes">redisinsights-with-persistent-volume-in-kubernetes</a>, where the Service was the issue.</p>
<p>However, if I add a <code>peristentVolumeClaim</code> the Pod starts and data is added to the mounted directory (i.e., it is an nfs share, with mod 777 and user/group 1001:1001 ownership), but RedisInsight is not accessible anymore (local on the Pod and externally via the Service).</p>
<p>I used the similar <code>yaml</code> files for other deployments and there they worked as expected.</p>
<p>The RedisInsight logs are empty.</p>

74,164,219 | <p>I need to express that a reference to a certain type parameter can be converted to a reference to another one.</p>
<p>Example:</p>
<pre class="lang-rust prettyprint-override"><code>trait TestTrait {}
struct TestStruct {}
impl TestTrait for TestStruct {}
fn test<Trait: ?Sized, Type>(object: &Type) -> &Trait
where ...
{
object
}
fn call_test()
{
let object = TestStruct{};
let t = test::<dyn TestTrait, TestStruct>(&object);
}
</code></pre>
<p>What do I need to put in the where clause?</p>
<p>EDIT: I don't want to be implementing From, AsRef, etc. I've considered those.</p>

74,164,264 | <p>As per the Riverpod documentation, asynchronously we use ref.read such as inside a function and for synchronous code, we use ref.watch such as inside the build method.</p>
<p>Once I press a button, the function with ref.read will fire up and it will be for only one time. Here, I should use ref.watch as it is now inside build method and with onPressed it will be ref.read</p>
<p>Case 1:</p>
<pre><code>// Bad practice
// Documentation says, "DON'T use ref.read inside the build method".
final counterProvider = StateProvider((ref) => 0);
Widget build(BuildContext context, WidgetRef ref) {
StateController counter = ref.read(counterProvider.notifier);
return ElevatedButton(
onPressed: () => counter.state++,
child: const Text('button'),
);
}
</code></pre>
<p>Case 2:</p>
<pre><code>// Good Practice
ElevatedButton(
onPressed: () => ref.read(counterProvider.notifier).state++,
child: const Text('button'),
),
</code></pre>
<p>Case 3:</p>
<pre><code>// Good Practice
Widget build(BuildContext context, WidgetRef ref) {
StateController counter = ref.watch(counterProvider.notifier);
return ElevatedButton(
onPressed: () => counter.state++,
child: const Text('button'),
);
}
</code></pre>
<p>In all 3 cases, code remains asynchronous since it is called only when the button is pressed then why is case1 bad and case 3 good practice?</p>

74,164,300 | <p>So I'm doing something stupid in my class solution because I am expecting a number but I get a zero. The code is as follows:</p>
<pre><code>class Spel
{
private int _nummer1;
public int Nummer1
{
get { return _nummer1; }
set { _nummer1 = value; }
}
private int _nummer2;
public int Nummer2
{
get { return _nummer2; }
set { _nummer2 = value; }
}
private int _nummer3;
public int Nummer3
{
get { return _nummer3; }
set { _nummer3 = value; }
}
private int _punten;
public int Punten
{
get { return _punten; }
set { _punten = value; bepaal(); }
}
public void bepaal()
{
Random rnd = new Random();
_nummer1 = rnd.Next(1, 4);
_nummer2 = rnd.Next(1, 4);
_nummer3 = rnd.Next(1, 4);
if (_nummer1 == _nummer2 && _nummer2 == _nummer3 && _nummer1 == _nummer3)
{
_punten = 10;
}
else if (_nummer1 == _nummer2 && _nummer2 == _nummer3)
{
_punten = 5;
}
else if (_nummer1 == _nummer2 && _nummer1 == _nummer3)
{
_punten = 5;
}
else if (_nummer2 == _nummer3 && _nummer1 == _nummer3)
{
_punten = 5;
}
}
</code></pre>
<p>I think the fault is in the area where I give the 'nummer' a random number.
Here is the code where I call the class with a controller:</p>
<pre><code>public class Controller
{
private Spel spl = new Spel();
public int getNummer1()
{
return spl.Nummer1;
}
</code></pre>
<p>In the next code I'm using the controller to bring up the class:</p>
<pre><code>private void button1_Click(object sender, EventArgs e)
{
teller++;
label1.Text = spl.getNummer1().ToString();
....
</code></pre>
<p>I don't know where the fault is so, can someone help me?</p>

74,164,316 | <p>I wanted a function to control and change a vector in rust. Here is a simplified version:</p>
<pre class="lang-rust prettyprint-override"><code>fn foo(vec: &mut Vec<i32>) {
for (i, element) in vec.iter().enumerate() {
// Some checks here
vec[(*element) as usize] = i as i32;
}
}
fn main() {
let mut bar: Vec<i32> = vec![1, 0, 2];
foo(&mut bar);
}
</code></pre>
<p>This code does not compile because there is both an immutable and a mutable borrow of <code>vec</code> in <code>foo</code>. I tried getting around this by copying <code>vec</code> to a separate copy, which didn't work and also wouldn't have been very pretty. What is the correct way to do this?</p>

74,164,386 | <h2>Issue:</h2>
<p>I created a web app in Flutter and deployed to the web using GitHub Pages. It worked on the first release (the page was functional, all content worked), and then I made some updates and attempted to redeploy and the web page now shows up blank. The screen is white. No content is displayed, and it only shows the generic title and favicon.</p>
<p>I am able to view the page normally when I run directly from Android Studio using Chrome. It is only when I deploy to the GitHub Pages that the screen is blank.</p>
<p>My process:</p>
<ul>
<li>Released using <code>flutter build web</code> command and also tried <code>flutter build web --release</code> and other combinations</li>
<li>Moving code from Android Studio to GitHub Pages by uploading the contents of the build > web folder to the main branch</li>
</ul>
<h2>What I have tried:</h2>
<p>Every combination of modifying removing the line that has been suggested in similar questions.</p>
<ul>
<li>Removing <code><base href=...></code></li>
<li><code><base href="/"></code></li>
<li><code><base href="./"></code></li>
<li><code><base href="/homepage/"></code></li>
<li>Removing and replacing the entire GitHub repo</li>
<li>Building using <code>flutter build web --web-renderer html</code></li>
<li>Removing all complex code from the app itself, leaving just a banner</li>

74,164,407 | <p>I have a line of code that should be spitting out the phrase "Testing 1"</p>
<p>Instead it's spitting out the letter "h".
The exact line of code is in reference to the link tag with in the UL/LI.</p>
<p>My goal is to have the link tag link to individual blogs however using the blog name which is currently referred to as more_blogs_title I am not sure why it is pulling an "h" in I can't find any issues within that line of code at the moment so looking for some help.</p>
<p>Thanks :)</p>

74,164,414 | <p>I have a <code>LazyColumn</code> with nested <code>LazyRows</code> (similar to Netflix or Spotify home page feed). In short, the issue I'm having is that when the content of the page changes, the scrolling positions of the nested LazyRows are not reset.</p>
<p>For example, user scrolls down the home page, scrolls the 3rd horizontal sections to see the 5th item, refreshes the home page, the new page content is loaded. But the 3rd horizontal section still shows the 5th instead of resetting to the initial position.</p>
<p>In terms of code, here's some snippets:</p>
<p>In HomeScreen composable:</p>
<pre><code> Scaffold {
when (val viewState = viewModel.stateFlow.collectAsState().value) {
is ViewState.Success -> {
Box {
with(viewState.data) {
LazyColumn {
itemsIndexed(sections) { index, section ->
LazyRow{}
//etc.
}
}
}
}
}
</code></pre>
<p>In the HomeViewModel, when user refreshes home screen this function is called:</p>
<pre><code>private val _stateFlow = MutableStateFlow<ViewState<HomePage>>(ViewState.Loading)
val stateFlow: StateFlow<ViewState<HomePage>>
get() = _stateFlow
fun loadHomeScreen() {
viewModelScope.launch {
repository.getHomePage()
.collect {
_stateFlow.tryEmit(it)
}
}
}
</code></pre>
<p>Now I have managed to add extra code to scrolls the home page's LazyColumn to the top of the screen when user refreshes the home screen. However, I still don't know what's the best way to do that for the nested LazyRows. I do not want to keep a reference to their <code>LazyListState</code> as that solution does not scale well. However, I am confused on why the scrolling position is not being reset when new state is emitted and new LazyRows are displayed. Is that a bug in Compose? Or am I missing something?</p>

74,164,460 | <p>please, I'm learning React with my simple TODO App. Everything now works OK. No errors or warnings (or issues in browser). But please, can you see the <code>console.log('PING!')</code>?</p>
<p>I'm using for list of tasks this loop:</p>
<pre class="lang-js prettyprint-override"><code><ul>
{tasks.map((task, index) => {
console.log('PING!');
return (
<Task id={task.id} name={task.name} isFinished={task.isFinished} key={index}
onActionButtonClick={handleActionButtonClick}/>
);
})}
</ul>
</code></pre>
<p><code>console.log()</code> it's just for show the problem. <code>handleActionButtonClick</code> is used to passing arguments from child <code>Task</code>.</p>
<p>But If I type the first task and hit enter (submit form). Everything is OK. I got <strong>PING!</strong> message once. But then it's called after every type new character. I'm using <code>onChange</code> event in <code><input></code>. Look here:</p>
<pre class="lang-js prettyprint-override"><code><input
id="newTaskInput"
type="text"
onChange={handleChange}
value={newTask}
placeholder="Add new task here..."
autoFocus
/>
</code></pre>
<p><code>handleChange</code> functions looks like here:</p>
<pre class="lang-js prettyprint-override"><code>const handleChange = (e) => {
if (e.target.value.length === 1) {
e.target.value = e.target.value.toUpperCase();
}
setNewTask(e.target.value);
};
</code></pre>
<p>This is called aways when I'm typing a new task (after the first one). Look on the screenshot please:</p>
<p><a href="https://i.stack.imgur.com/6zQPJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/6zQPJ.png" alt="enter image description here" /></a></p>
<p>You can see the first <strong>PING!</strong> was called after submit <code>Butter</code> item. But then I'm typing a new item called <code>Milk</code> and you can see 4x <strong>PING!</strong> message in console. But I'm just setting the state called <code>setNewTask</code> which is <code>useState</code>. Look at the definition:</p>
<pre class="lang-js prettyprint-override"><code>function App() {
const [newTask, setNewTask] = useState('');
const [tasks, setTasks] = useState([]);
const [editTaskId, setEditTaskId] = useState();
// other code
}
export default App;
</code></pre>
<p>I will be glad if someone can explain me why is <code>map</code> function is called everytime after the first submit and how to avoid it. Thanks to any advice</p>
<p>For better understand my logic here is whole code please:</p>
<pre class="lang-js prettyprint-override"><code>import React, { useState } from 'react';
import Task from './components/Task';
import Header from './components/Header';
function App() {
const [newTask, setNewTask] = useState('');
const [tasks, setTasks] = useState([]);
const [editTaskId, setEditTaskId] = useState();
const handleChange = (e) => {
if (e.target.value.length === 1) {
e.target.value = e.target.value.toUpperCase();
}
setNewTask(e.target.value);
};
const handleSubmit = (e) => {
e.preventDefault();
if (editTaskId > 0) {
//editing exisitng task
let newTasksArray = [...tasks];
let newTask = newTasksArray[editTaskId];
newTask.name = newTask;
setTasks(newTasksArray);
} else {
//creating new task
setTasks([
{
id: [...tasks].length === 0 ? 0 : Math.max(...tasks.map((task) => task.id)) + 1,
name: newTask,
isFinished: false,
},
...tasks,
]);
}
setNewTask('');
};
const handleActionButtonClick = (buttonValues) => {
switch (buttonValues.type) {
case 'edit':
tasks.map((task) => {
if (task.id === buttonValues.id) {
setNewTask(task.name);
setEditTaskId(task.id);
return;
}
});
break;
case 'delete':
setTasks(tasks.filter((task) => task.id !== buttonValues.id));
break;
default:
//TODO: We shoudn't reverse array. Instead of that we shoud find a right id in a array and change value
console.log(buttonValues.id);
let newTasksArray = [...tasks].reverse();
let newTask = newTasksArray[buttonValues.id];
//if task if already finished we can return state
if (newTask.isFinished) newTask.isFinished = false;
else newTask.isFinished = true;
setTasks(newTasksArray.reverse());
}
};
return (
<>
<Header />
<div className="container">

console.log('PING!');
return (

74,164,494 | <p>I'm new to RXJS and would to know if what I am doing is best practice. I have an API whihc returns a list of countries. I need to use this list in several different components. I have an external api that returns this, it can be very slow.</p>
<p>I have a service to call this API. In the constructor of this service I kick off the HTTP request which then passes the list to a BehaviorSubject. I need to use the unedited list in one component this subscribes the BehaviorSubject. Another component will use selected values from the list and I am using the getCountryById function to do this and return a single value in a string</p>
<p>Should I be using AsyncSubject to do this and is it bad practice to use this.CountriesSubject.value in my getCountryById function, should I also be using a BehaviorSubject.subscribe in there as well?</p>
<p>All of this does need to happen in the service</p>
<p>Thanks for your time :-)</p>
<pre><code> export class CountryListService implements OnDestroy {
private baseUrl = 'api/countries/';
private CountriesSubject = new BehaviorSubject<country[]>([]);
Countries$: Observable<Country[]> = this.CountriesSubject.asObservable();
constructor(private http: HttpClient) {
this.getCountries();
}
getCountries() {
console.log('=======fetching Countries from API');
this.http.get<any>(this.baseUrl + 'Countries').subscribe((data) => this.CountriesSubject.next(data?.countries));
}
getCountryById(id: any[]) {
if (!this.CountriesSubject.value) {
return undefined;
}
const country = this.CountriesSubject.value.find((f) => {
//Logic in here to get a country by and return its name
});
return country?.name;
}
ngOnDestroy() {
this.CountriesSubject.complete();
}
}

74,164,507 | <p>Hi guys I'm new to JavaScript. I'm trying to get the Date and Time in a non-editable textbox in this format:
(e.g. 7 October
2022 Friday 10:47). The content is the current date or todayβs date which will change every
day.</p>
<p>Currently these are my codes:</p>
<pre><code>function getDate()
{
const date = new Date();
const months = [ "January",
"February",
"March",
"April",
"May",
"June",
"July",
"August",
"September",
"October",
"November",
"December" ];
const days = [ "Monday",
"Tuesday",
"Wednesday",
"Thursday",
"Friday",
"Saturday"
"Sunday" ];
document.getElementById("dateandtime").value = months[(date.getMonth()+1)] + (date.getFullYear()) + days[(date.getDay())] + (date.getHours()) + ':' +(date.getMinutes());
}
</code></pre>
<pre><code> Current Date and Time:
<br/>
<input type = "text" id = "dateandtime" name = "dateandtime" onload="getDate()" readonly>
<br/><br/>
</code></pre>
<p>However, when I run it, nothing is displayed in my textbox.</p>
<p>Any idea why that is the case?</p>

74,164,521 | <p>The question says to write a function that takes a string of braces, and determines if the order of the braces is valid. It should return true if the string is valid, and false if it's invalid.</p>
<p>All input strings will be nonempty, and will only consist of parentheses, brackets and curly braces: ()[]{}.</p>
<p>The tests should give these:</p>
<pre><code>"(){}[]" => True
"([{}])" => True
"(}" => False
"[(])" => False
"[({})](]" => False
</code></pre>
<p>The code I've written is:</p>
<pre><code>def validBraces(braces)
revBraces = braces.reverse
arr = []
i = -1
loop do
i += 1
if braces[i] == "(" && revBraces[i] == ")"
arr << 1
else
arr << 0
end
if braces[i] == ")" && revBraces[i] == "("
arr << 1
else
arr << 0
end
if braces[i] == "{" && revBraces[i] == "}"
arr << 1
else
arr << 0
end
if braces[i] == "}" && revBraces[i] == "{"
arr << 1
else
arr << 0
end
if braces[i] == "[" && revBraces[i] == "]"
arr << 1
else
arr << 0
end
if braces[i] == "]" && revBraces[i] == "["
arr << 1
else
arr << 0
end
break if i <= braces.length
end
if arr.include? 0
puts false
else
puts true
end
end

74,164,546 | <p>So I have a dataframe structured like:</p>

2020-01-01 Low 34.5
2020-01-01 High 36.5
2020-01-01 Open 23.5
2020-01-02 Low 32.5

<p>I am trying to create another frame, where for every date there is a new 'Volume' column which is the High-low for that specific date. The frame is not keyed on the dates so it needs to be joined and then values in different columns added together? Not sure exactly how to do this. I'm trying to get the final result to look like this:</p>
<pre><code>Date Volume
2020-01-01 2.00
2020-01-02 6.45

74,164,563 | <p>I'm an absolute beginner - like I'm Today-years-old with this.</p>
<p>So I'm mucking about with a silly little piece of code to try and help me understand If statements:</p>
<pre><code>print ('How many sausages have you eaten today?')
userInput = ('>5' or '<5')
if userInput input == int ('> 5'):
print ('Whoa! Slow down Fatty!')
elif userInput input == ('< 5'):
print ('Ok, but better call it a day now')
</code></pre>
<p>I'm trying to alter the printed message based on how many sausages the user inputs - e.g. above 5 or below 5.
I know that I'm doing something (probably many things) wrong.
Can anyone help to tidy this up?</p>

74,164,603 | <h1>Objective</h1>
<ul>
<li>Display a 3D <strong>Sphere</strong> graph structure based on input edges & nodes using VTK for visualisation. As for example shown in <a href="https://epfl-lts2.github.io/gspbox-html/doc/graphs/gsp_sphere.html" rel="nofollow noreferrer">https://epfl-lts2.github.io/gspbox-html/doc/graphs/gsp_sphere.html</a></li>

<p><a href="https://i.stack.imgur.com/r6Bta.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/r6Bta.png" alt="enter image description here" /></a></p>
<h1>State of work</h1>
<ul>
<li>Input data as given factor</li>
<li>NetworkX for position calculation</li>
<li>Handover to VTK methods for 3D visualisation</li>
</ul>
<h1>Problem</h1>
<p>3 years ago, I had achieved the visualisation as shown above. Unfortunately, I did a little bit of too much cleaning and I just realized, that I dont have these methods anymore. It is somehow a force-directed graph on a sphere surface. Maybe similar to the "strong gravity" parameter in the 2D forceatlas. I have not found any 3D implementation of this yet.</p>
<p>I tried again with the following algorithms, but none of them has produced this layout, neither have parameter tuning of these algorithms (or did I miss an important one?):</p>
<ul>
<li>NetworkX: Spherical, Spring, Shell, Kamada Kawaii, Fruchterman-Reingold (the 2D fruchterman-reingold in Gephi looks like it could come close to the target in a 3D version, yet gephi does not support 3D or did I oversee something?)</li>
<li>ForceAtlas2</li>
<li>Gephi (the 2D fruchterman-reingold looks like a circle, but this is not available in 3D, nor does the 3D Force Atlas produce valid Z-Coordinates (they are within a range of +1e-4 and -1e-4)</li>
</ul>
<p>Researching for "spherical graph layout" has not brought me to any progress (only to this view which seems very similar <a href="https://observablehq.com/@fil/3d-graph-on-sphere" rel="nofollow noreferrer">https://observablehq.com/@fil/3d-graph-on-sphere</a> ).</p>
<p>How can I achieve this spherical layout using python (or a third party which provides a positioning information)</p>
<p><strong>Update:</strong> I made some progress and found the keywords non-euclidean, hyperbolic and spherical force-directed algorithms, however still not achieved anything yet. Or Non-Euclidean Riemann Embeddings (<a href="https://www2.cs.arizona.edu/%7Ekobourov/riemann_embedders.pdf" rel="nofollow noreferrer">https://www2.cs.arizona.edu/~kobourov/riemann_embedders.pdf</a>)</p>

74,164,604 | <p>I am trying to search and replace certain words in my .xml file and replace it with another, but I struggle a bit.</p>
<p>I have been using this code so far:</p>
<pre><code>import xml.etree.ElementTree as ET
with open('Rom1.xml', encoding="utf8") as f:
tree = ET.parse(f)
#root = tree.find('ExportedObjects')
root = tree.getroot()
for elem in root.iter():
try:
elem.text = elem.text.replace('Rom1', 'Rom2')
except AttributeError:
pass
</code></pre>
<p><a href="https://i.stack.imgur.com/rdPUC.png" rel="nofollow noreferrer">Rom1.xml</a> this is a snapshot from the XML file showing the structure</p>
<p>The XML file is pretty big but it contains the string 'Rom1' 41 times and I would like to replace all of them.</p>
<p>I know a simple search and replace in text editor does the job, but I want to automate this since I will do it for several hundered of files.</p>
<p>Any help is appriciated :)</p>

74,164,643 | <p>In C, you can use the <code>static</code> keyword to make global variables and functions private to the file in which they're defined. The compiler won't export these symbols, and thus the linker will not allow other modules to use these definitions.</p>
<p>However, I'm struggling to figure out how to restrict a struct definition such that it doesn't get added as an exported symbol that could accidentally be used by another module during the linking process. I would like to restrict this to the only file in which its defined.</p>
<p>Here are my attempts thus far which I've been struggling with.</p>
<pre><code>// structure that is visible to other modules
struct PrivateStruct
{
int hello;
int there;
};
// this seems to throw an error
static struct PrivateStruct
{
int hello;
int there;
};
// i would ideally like to also wrap in the struct in a typedef, but this definitely doesn't work.
typedef static struct PrivateStruct
{
int hello;
int there;
} PrivateStruct;
</code></pre>
<p>Edit: I realize if I just define this struct in the .c file, others won't know about it. But won't it still technically be an exported symbol by the compiler? It would be nice to prevent this behavior.</p>

74,164,647 | <p>I've bound an enum to a combobox in WPF using a method a friend showed me instead of everything I've found online. What I need to do is convert the selected item from the dropdown back to an enum because I'm using it to set a property. I'm new to WPF and C# so I'm not even sure I'm properly asking the question, therefor not finding the answer I need.</p>
<pre><code> private void cmbInputPath_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
FM.InputPath = cmbInputPath.SelectedItem;
}
</code></pre>
<p>Here is the property that uses the enum.</p>
<pre><code>public Input InputPath
{
set
{
switch (value)
{
case Input.DIPLEXER:
SetSwitchPosition(SWC3.CurrentPosition, SWC3.P7);
break;

74,164,650 | <p>So, I saw a related 'topic' question on here, but it is using a different method.</p>
<p>Further, I understand there are more efficient algorithms out there such as Mid-point/Bresenham's.</p>
<p>Yet, at least thus far in my discovery, perhaps 'simple and traditional' is best for my needed end-point application.</p>
<p>Thus I put together this tiny Python app to experiment. I needed to at least ensure that descending radii of a circle described this way would cover the area. Again, I fully understand there would be much easier ways to make a circle, and a fill--</p>
<p>But that is not really what I'm after. I just need to determine a list of all the (x,y) pixel points, in the end, that describe it.</p>
<p>However, at first, this is of course much easier to see 'visually'.</p>
<p>So, from my simple code:</p>
<pre><code>from PIL import Image
import math
import numpy as np
img = Image.new('RGB', (800, 800), color = (255, 255, 255))
x = 400
y = 400
#r = 300
for r in range(0, 300, 1):
for i in np.arange(0, 361, 0.1):
angle = i
x1 = math.trunc(r * math.cos(angle * math.pi / 180))
y1 = math.trunc(r * math.sin(angle * math.pi / 180))
#print ("(" + str(x + x1) + "," + str(y + y1) + ")")
img.putpixel((x + x1, y + y1), (0, 0, 0, 255))
img.show()
</code></pre>
<p>I guess I am a little confused as to how/why I am blanking out in these four points, one in each quadrant, almost exactly like a square:</p>
<p><a href="https://i.stack.imgur.com/xragJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xragJ.png" alt="enter image description here" /></a></p>
<p>Anyone have a guess 'what gives ?'</p>

74,164,719 | <p>What's the best way I can get a list of BSD names of all USB devices (and maybe including internal Mac drives) without using a <b>diskutil</b> CLI wrapper?</p>
<p>I <b>don't want</b> to use any <b>wrappers</b> that interact with the CLI interface, as this way of interacting is quite <b>slow</b> and <b>unreliable</b>:</p>
<p><a href="https://i.stack.imgur.com/JMcB8.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/JMcB8.jpg" alt="" /></a></p>

<p>What is the best way to implement the solution for my problem?<br />
Use the data from <b>IOReg</b>?<br />
If yes, how can I get a list of BSD names of connected devices using it?</p>
<p>Here is an example what I want to get:</p>
<pre><code>["disk0", "disk0s1", "disk0s2", "disk0s3", "disk1", "disk1s1", "disk1s2", "disk1s3", "disk1s4", "disk2", "disk2s1", "disk2s2", "disk3", "disk3s1", "disk3s1s1", "disk3s2", "disk3s3", "disk3s4", "disk3s5", "disk3s6", "disk4", "disk4s1", "disk4s2", "disk5", "disk5s1", "disk5s2", "disk6", "disk6s1", "disk6s2", "disk10", "disk10s1", "disk10s2", "disk11", "disk11s1"]
</code></pre>
<p>At the moment, I have the following:</p>
<pre><code>static func getMountedBSDNames() -> [String] {
guard let session = DASessionCreate(nil) else { return [] }
guard let mountedVolumeURLs = FileManager.default.mountedVolumeURLs(includingResourceValuesForKeys: nil) else { return [] }

BSDNames.append(
String(cString: BSDName)
)
}
}
return BSDNames
}

<p>But in this case, <b>only mounted</b> are returning.<br />
I want there to have even those, that were <b>ejected</b></p>

This is the traceback.</p>

<p>Edit2:
These are the warnings which I Kind of find confusing?</p>
<blockquote>
<p>Line 6 : Name "Image" already defined (possibly by an import)</p>
<p>Line 6 : Unused ImageTk imported from PIL
It looks like the imported module or variable is not used.</p>

<a href="https://i.stack.imgur.com/ofEur.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ofEur.png" alt="enter image description here" /></a></p>
<p>I've just started to code in python and coded a calculator (its unfinished atm) it works fine except for the fact that "none" keeps popping up in the output. Here is my code.</p>
<pre><code>num1 = float(input(print("Enter the first value ")))
num2 = float(input(print("Enter the second value ")))
operator = input("Enter the operator you want to calculate with;+,-,* ")
sum = num1+num2
product = num1*num2
difference = num1-num2
if operator == "+":
print(sum)
elif operator=="*":
print(product)
else:
print(difference)
</code></pre>
<p>Output:</p>
<pre><code>None 1
Enter the second value
None 2
Enter the operator you want to calculate with;+,-,*
3.0
</code></pre>
<p>Any fixes available for this? I've seen another query with the same issue but different code so I didn't understand that a bit.</p>

74,164,859 | <p>I have this table <code>Test</code>:</p>
<pre><code>ID - int primary key not null,
CODE - nvarchar(max),
NAME - nvarchar(max)
</code></pre>
<p>It has clustered index on <code>ID</code>.</p>
<p>But in an execution plan, the search uses <code>ID</code> and <code>CODE</code> columns.</p>
<p>How can I add non-clustered index to the table? When I try, I get an error:</p>
<blockquote>
<p>Column code in table Test is of a type that is invalid for use as a key column in an index</p>
</blockquote>
<p>Could you recommend what actions must be done?</p>
<p>I need to add the index for the query fast processing.</p>
<p>There is already clustered index which is not effective in query processing.</p>
<p>In SSMS, for creating NON-CLUSTERED INDEX - the only option was to add <code>ID</code> as key column and then to add CODE as <code>Include</code> in the index. But it means that table will have both CLUSTERED INDEX on ID column and NON-CLUSTERED INDEX on ID with CODE include. Is that right?</p>
<p>What is the best practice:</p>
<ul>
<li>If table can have both clustered and non-clustered indexes basing on same id key column?</li>
<li>How should you do for fixing the problem?</li>

74,164,893 | <p>I have been trying to solve this problem for more than a week, but finally I am forced to ask for help.</p>
<p>I am just implementing a search filter in Vue 2, using Vuetify, but something is going wrong</p>
<p>This is how the search filter looks:</p>
<pre><code> <v-text-field v-model="search" label="Look for name..."></v-text-field>
</code></pre>
<p>I have a variable called search in the component data that is two-binding with the text-field v-model</p>
<p>Secondly, I have an array of items:</p>
<pre><code>items: [
{
default: true,
name: 'Text 1',
},
{
default: false,
name: 'Text 2',
},
{
default: false,
name: 'Text 3',
},
{
default: false,
name: 'Text 4',
},
],
</code></pre>
<p>I render the list in a div using v-for</p>
<pre><code><div v-for="(item, index) in filteredItems">
<div style="display: flex">
<input
type="radio"
:checked="item.default"
@click="changeDefault(item, index)"
/>
<h1>{{ item.name }}</h1>
</div>
</div>
</code></pre>
<p>This is how the component looks:
<a href="https://i.stack.imgur.com/mYRvX.png" rel="nofollow noreferrer">List and search filter rendered</a></p>
<p>How the filter works? Here is the code</p>
<pre><code>filteredItems() {
if (this.search) {
return this.items.filter((item) => {
return item.name.toLowerCase().match(this.search);
});
} else {
return this.items;
}
},
</code></pre>
<p>As you can see in the rendered list, items have a radio button which can be selected. When some of them are clicked, we call a function called <em>changeDefault</em> whose code is this (just get the default true item and set it to false, and the new one to true)</p>
<pre><code>changeDefault(item, index) {
let indexOfDefaultTrue = this.items.findIndex((item) => item.default === true);
this.items[indexOfDefaultTrue].default = false;
this.items[index].default = true;
},
</code></pre>
<p>All seems to be working, but the issue is that, if i search for Text 2 (for instance) and click the radio button, it turns to active, but when i clear the filter, it seems like nothing happened
It only happens if i use the search method, if i click an item on the initial list, radio button changes properly.
<a href="https://i.stack.imgur.com/vxYaY.png" rel="nofollow noreferrer">Text 2 search</a>
<a href="https://i.stack.imgur.com/iGkRa.png" rel="nofollow noreferrer">After i clear the search</a></p>
<p>It looks like the list didnt render the new items or something like that? Im big stucked.
Thank you very much, i wish someone can help me!</p>

74,164,953 | <p>Given the following code:</p>

#include <cstddef>

template<std::size_t N>
struct StringWrapper {

// This here to motivate not using StringWrapper as non-type template argument

// variadic template, thus putting std::source_location at the end is not an option
template<std::size_t N, class... Args>
void log(StringWrapper<N> format_string, Args&&... args);
int main()
{
log(StringWrapper{ "This {}, explicitly instantiating, but deducing the parameter" }, "works");
log("This {}, could not match 'StringWrapper<N>' against 'const char *'", "fails");
}
</code></pre>
<p>What could be a possible workaround to this issue that would not require a change on the callsite?</p>
<p>One possibility is to use a <code>std::string_view</code>, however that would not give me access to <code>N</code> as a constant expression in the implementation of <code>log</code> and is thus not an option in my case.</p>
<p>Another possibility is to directly take a <code>const char (&)[N]</code>, however then I am losing the <code>std::source_location</code> which is not an option either.</p>
<p>I understand why overload resolution would favor a function that takes a <code>const char*</code> over a function that takes a <code>const char (&)[N]</code>, however I do not understand why 'StringWrapper' is not even attempted to match against 'const char (&)[N]' however.</p>

<p>The code above works but we are concerned about performance on much larger arrays of objects in our react application. Also not sure if mutating the array inside of a <code>forEach()</code> is considered a bad practice in React, perhaps it is better to create a new array somehow with <code>.map()</code>. Any recommendations on the best way to replace <code>undefined</code> with <code>0</code>?</p>

</StudentBreakdown>
</code></pre>
<p>My code is iterating through the studentinfo.xml file and inputting the information into a <code>pandas</code> dataframe(df1) per the columns I've mapped the tags to.</p>
<p>Below is a sample of my code:</p>
<pre><code>import pandas as pd
from bs4 import BeautifulSoup
with open('studentinfo.xml', 'r') as f:
file = f.read()
def parse_xml(file):
soup = BeautifulSoup(file, 'xml')
df1 = pd.DataFrame(columns=['StudentName', 'Age', 'Hair', 'Eyes', 'Grade', 'Teacher', 'Dorm'])
all_items = soup.find_all('info')
items_length = len(all_items)
for index, info in enumerate(all_items):
StudentName = info.find('<name>').text
Age = info.find('<age>').text
Hair = info.find('<hair>').text
Eyes = info.find('<eyes>').text
Grade = info.find('<grade>').text
Teacher = info.find('<teacher>').text
Dorm = info.find('<dorm>').text
row = {
'StudentName': StudentName,
'Age': Age,
'Hair': Hair,
'Eyes': Eyes,
'Grade': Grade,
'Teacher': Teacher,
'Dorm': Dorm
}
df1 = df1.append(row, ingore_index=True)
print(f'Appending row %s of %s' %(index+1, items_length))
return df1
</code></pre>
<p>When I try to run the code I get this error:
'AttributeError: 'NoneType' object has no attribute 'text''
Which my conclusion as to why I was getting this error was because not every StudentScreening has the same child tags being used.</p>
<p>What condition can be added to my code that says:
" As I am looping through, If an element tag is not present, input null in the dataframe and continue to enumerate over the file"
??????</p>

74,165,123 | <p>I have a web service that returns an SseEmiter, i am using it to program a loading bar but...Well, the method to receive it is this:</p>
<pre><code>static async synchronize(component: Vue) {
let xhr = new XMLHttpRequest();
xhr.open('PATCH', 'myUrl.com');
xhr.responseType = "text"
xhr.setRequestHeader('Authorization', 'mySessionToken')
xhr.setRequestHeader("Content-Type", "text/event-stream")
xhr.onload = function () {
if (this.status >= 200 && this.status < 300) {
resolve(xhr.response)
} else {
reject({status: this.status, statusText: xhr.statusText})
}
}
xhr.onerror = function () {reject({status: this.status, statusText: xhr.statusText})}
xhr.onreadystatechange = function() {if (xhr.readyState == XMLHttpRequest.DONE) { alert(xhr.responseText) }}
xhr.onprogress = function(onEvent) {
console.log(xhr.response)
}
xhr.send()
}
</code></pre>
<p>Right now this works, but...The <code>xhr.response</code> data returns this as a string.</p>
<pre><code>data:"{ hello: '1' }"
data:"{ hello: '2' }"
data:"{ hello: '3' }"
data:"{ hello: '4' }"
data:"{ hello: '5' }"
data:"{ hello: '6' }"
data:"{ hello: '7' }"
data:"{ hello: '8' }"
data:"{ hello: '9' }"
data:"{ hello: '10' }"
data:"{ hello: '11' }"
data:"{ hello: '12' }"
data:"{ hello: '13' }"
data:"{ hello: '14' }"
data:"{ hello: '15' }"
data:"{ hello: '16' }"
data:"{ hello: '17' }"
data:"{ hello: '18' }"
data:"{ hello: '19' }"
//And so on until it reach 100.
</code></pre>
<p>This doesn't seem like a problem, but what happens is that on each emitted event, the entire state history is returned, getting larger with each value:</p>
<p><a href="https://i.stack.imgur.com/FCcyu.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FCcyu.png" alt="enter image description here" /></a></p>
<p>In short, is there any way to get ONLY the last value of such response? <code>Json.parse()</code> is throwing errors, probably because the response is not formatted as json.</p>
<p>I could share some code of the web service where the SseEmitter comes from, but i don't think it's necessary to resolve this. Thanks for any help!</p>

74,165,151 | <p>Let's say I have following python code:</p>
<pre><code>import numpy as np
import matplotlib.pyplot as plt
fig=plt.figure()
ax=plt.axes(projection='3d')
x=y=np.linspace(1,10,100)
X,Y=np.meshgrid(x,y)
Z=np.sin(X)**3+np.cos(Y)**3
ax.plot_surface(X,Y,Z)
plt.show()
</code></pre>
<p>How do I calculate from this code the gradient and plot it? I am also confused in what numpy.gradient() function exaclty returns.</p>
<p>I have here the graph of the function.

74,165,156 | <p>So I want to change many arrays in a similar way but I'm wondering if instead of doing something like this</p>

attack1[0] = attacks[i];
attack1[1] = Convert.ToString(atdmg[i]);

attack1[3] = Convert.ToString(ataccur[i]);
attack1[4] = Convert.ToString(atmul[i]);

if (i == 1)

attack2[0] = attacks[i];
attack2[1] = Convert.ToString(atdmg[i]);
attack2[2] = ateffect[i];
attack2[3] = Convert.ToString(ataccur[i]);
attack2[4] = Convert.ToString(atmul[i]);

attack3[0] = attacks[i];

attack3[2] = ateffect[i];
attack3[3] = Convert.ToString(ataccur[i]);
attack3[4] = Convert.ToString(atmul[i]);

if (i == 3)
{
attack4[0] = attacks[i];
attack4[1] = Convert.ToString(atdmg[i]);
attack4[2] = ateffect[i];
attack4[3] = Convert.ToString(ataccur[i]);
attack4[4] = Convert.ToString(atmul[i]);
}

</code></pre>
<p>I could do something like this</p>
<pre><code>for (int i = 0; i < 4; i++)
{
attacki[0] = attacks[i];
attacki[1] = Convert.ToString(atdmg[i]);
attacki[2] = ateffect[i];
attacki[3] = Convert.ToString(ataccur[i]);
attacki[4] = Convert.ToString(atmul[i]);
}
</code></pre>
<p>so that I don't have to type each one. The point of the code is to put information from other arrays into other arrays to simplify printing information in the long run</p>

74,165,197 | <p>recently I was forced to migrate from VPS hosting I had. I was away from home when I was asked to perform backups before the end of lease, so I had no time to backup all of the data in a way that backup should've been performed and that left me with all of my VPS data packed into a single .tar.gz.</p>
<p>Almost everything went smooth, the last thing that gives me nightmares is restoring my previous Gitlab-CE data.</p>
<p>This time I went with the dockerized version of Gitlab-CE. (gitlab/gitlab-ce:12.4.0-ce.0)</p>
<p>To be sure that I am not using wrong version during this process, I extracted which version I had installed from one of license files found in the backup.</p>
<p>I have confirmed that this image works without my data being mounted to volumes, but whenever I've tried to mount volumes recovered from backup:</p>
<blockquote>
<p>/home/gitlab/logs:/var/log/gitlab</p>
<p>/home/gitlab/data:/var/opt/gitlab</p>
<p>/home/gitlab/config:/etc/gitlab</p>
</blockquote>
<p>I was stuck with a fatal error regarding postgres db:</p>
<blockquote>
<p>[execute] psql: FATAL: database locale is incompatible with operating system</p>
<p>DETAIL: The database was initialized with LC_COLLATE "en_US.UTF-8", which is not recognized by setlocale().</p>
<p>HINT: Recreate the database with another locale or install the missing locale.</p>
</blockquote>
<p>I have tried setting ENV variables <strong>LANG, LANGUAGE, LC_ALL</strong> to different values without any luck.</p>
<p>I was not able to find solution on the internet so far, I wish I could've made a backup properly.</p>
<p>My wish is to restore old repositories (and if possible user accounts) from old installation I have stored.</p>
<p>Anything that could lead me into possible solution is very much appreciated!</p>
<p><em>This is my first question on stack so please forgive me if it is formed improperly, or is being asked in a wrong section.</em></p>

74,165,310 | <p>edit: meant 'null termination' wherever 'padding' is used.</p>
<p>I am using the following function to compare a string (in this case the argv[1]) to an array of accepted arguments.</p>
<pre><code>const char *ARGS_HELP[] = {"-h", "--help", "-help", "help", NULL};
const char *ARGS_BUILD[] = {"-b", "--build", NULL};
int strcmp_array(char *a, const char *b[])
{
//printf("a = \"%s\" b[0] = \"%s\" b[1] = \"%s\" b[2] = \"%s\" b[3] = \"%s\" b[4] = \"%s\" b[5] = \"%s\" b[6] = \"%s\ \n",a,b[0],b[1],b[2],b[3],b[4],b[5],b[6]);
int len = 0;
while (b[len] != NULL)
{
len++;
}
for (int i = 0; i < len; i++)
{
//printf("Comparing \"%s\" to \"%s\"\n",a,b[i]);
if (strcmp(a, b[i]) == 0)
{
return 0;
}
}
return 1;
}
int main(int argc, char *argv[])
{
if (argc == 1 || strcmp_array(argv[1], ARGS_HELP) == 0)
{
printf("%s", HELP_PAGE);
return 0;
}
}
</code></pre>
<p>I noticed that when I ran my program with "--build" as argv[1], it would still trigger the help page. I wondered why since ARGS_HELP and ARGS_BUILD are two separate const char arrays.
I noticed strcmp_array was looping through all the possible combinations. This is because I had not inserted NULL at the ends of each array to signify its end. Who can explain why this happens, why doesn't the compiler automatically insert a NULL character at the end of the const char arrays?</p>
<p>With padding</p>
<pre><code>const char *ARGS_HELP[] = {"-h", "--help", "-help", "help", NULL};
const char *ARGS_BUILD[] = {"-b", "--build", NULL};
a = "--build" b[0] = "-h" b[1] = "--help" b[2] = "-help" b[3] = "help" b[4] = "(null)" b[5] = "(null)" b[6] = "-b"
</code></pre>
<p>Without null padding</p>
<pre><code>const char *ARGS_HELP[] = {"-h", "--help", "-help", "help"};
const char *ARGS_BUILD[] = {"-b", "--build"};
a = "--build" b[0] = "-h" b[1] = "--help" b[2] = "-help" b[3] = "help" b[4] = "-b" b[5] = "--build"
</code></pre>
<p>I should always pad my char arrays with NULL from now on?</p>
<p>I am not a computer scientist. I am relatively new to C.</p>

74,165,313 | <p>I want to create <code>ori.same.maf.barcodes</code> variable to store the strings of <code>ori.maf.barcode</code> if the substrings before fourth "-" character matches the strings in <code>sub.same.barcodes</code>.</p>
<p>How <code>sub.same.barcodes</code> and <code>ori.maf.barcode</code> were generated. <code>sub.maf.barcode</code> is the subset of the <code>ori.maf.barcode$Tumor_Sample_Barcode</code>. The <code>sub.same.barcodes</code> is the intersect of <code>sub.maf.barcode</code> and <code>sub.met.barcode</code>. Now, I want to match <code>sub.same.barcodes</code> back to <code>ori.maf.barcode</code>.</p>
<pre><code>ori.maf.barcode <- maf@clinical.data
sub.maf.barcode <- gsub("^([^-]*-[^-]*-[^-]*-[^-]*).*", "\\1", ori.maf.barcode$Tumor_Sample_Barcode) # Remove the dashes and keep only the first 4
sub.same.barcodes <- intersect(sub.maf.barcode, sub.met.barcode)
</code></pre>
<p>Attempt:</p>
<pre><code>ori.same.maf.barcodes <- ori.maf.barcode %in% sub.same.barcodes
</code></pre>
<p>But my code returns "FALSE" instead of a character vector.</p>
<p><code>dput(ori.maf.barcode[1:20])</code></p>

74,165,352 | <p>my problem is that the heading "greeting" influences the position of my navigation bar.<br />
I want it to stay at the top right corner of the screen but the heading moves it down a bit, which is inconvenient.<br />

74,165,449 | <p>Referencing the snippet below, I would like to be able to call <code>f</code> only with an object having a single property. Typescript should complain about additional properties, even when set to <code>undefined</code>.</p>
<pre class="lang-js prettyprint-override"><code>interface A {
a: number;
b?: never;
}
interface B {
a?: never;
b: number;
}
const f = (arg: A | B) => {};
// OK
f({ a: 0 });
// Error: Type 'number' is not assignable to type 'undefined'.
f({ a: 0, b: 0 });
// OK, but I would like to have an error
f({ a: 0, b: undefined });
</code></pre>
<p>In my case <code>f</code> is a <a href="https://beta.reactjs.org/apis/react/useReducer#dispatch" rel="nofollow noreferrer">useReducer dispatcher</a> which if called with <code>{ a: 0, b: undefined }</code> would set the property <code>b</code> of my component state to <code>undefined</code>, while if called with <code>{ a: 0 }</code> would leave the property <code>b</code> alone.</p>
<p>There is no reason why I would ever dispatch an <code>{ a: 0, b: undefined }</code> action, but still, is there a way to have TypeScript covering my shoulders?</p>

74,165,500 | <p>I have various implementations of a <code>partial class DeviceServices</code> to provide platform specific implementations of certain device or OS specific features for Android, iOS and so on. My app is targeting API level 33.0 and the minimum version is API level 21.0.</p>
<p>Some APIs are specific to certain Android versions and higher, so I want to make sure that they only get called on the supported version. However, I always receive the following warning (and similar ones depending on the API being used):</p>
<p><em><strong>warning CA1416: This call site is reachable on: 'Android' 21.0 and
later. 'WindowInsets.Type.SystemBars()' is only supported on:
'android' 30.0 and later.</strong></em></p>
<p>The following code to hide and show the system bars works on all my devices and the emulators that I have tried so far, but I am concerned about earlier Android versions. I still receive the warning above with it despite checking for the correct target API version:</p>
<pre class="lang-cs prettyprint-override"><code>static partial class DeviceServices
{
private static Activity _activity;
public static void SetActivity(Activity activity)
{
_activity = activity;
}
public static partial void HideSystemControls()
{
#if ANDROID30_0_OR_GREATER
if (Build.VERSION.SdkInt >= BuildVersionCodes.R) //R == API level 30.0
{
_activity?.Window?.InsetsController?.Hide(WindowInsets.Type.SystemBars());
}
#endif
}
public static partial void ShowSystemControls()
{
#if ANDROID30_0_OR_GREATER
if (Build.VERSION.SdkInt >= BuildVersionCodes.R) //R == API level 30.0
{
_activity?.Window?.InsetsController?.Show(WindowInsets.Type.SystemBars());
}
#endif
}
}
</code></pre>
<p>So, what is the correct way to do this? I'm not sure how to proceed. I've used platform-specific APIs plenty of times and never had any problems with it before, but this warning concerns me. I had a look at the support article about this warning already, too, but I didn't find it very helpful: <a href="https://learn.microsoft.com/en-us/dotnet/fundamentals/code-analysis/quality-rules/ca1416" rel="nofollow noreferrer">https://learn.microsoft.com/en-us/dotnet/fundamentals/code-analysis/quality-rules/ca1416</a>. I also don't want to suppress the warnings. Maybe I am missing something here or can I simply ignore the warning in this case?</p>
<p><strong>Update:</strong></p>
<p>I am using Visual Studio 2022 17.4 Preview 2.1 and .NET 7.0 RC1.</p>
<p>I have also tried calling the APIs directly from within the <code>MainActivity</code>, but keep receiving the same warnings after a rebuild.</p>
<p><strong>Update 2:</strong></p>
<p><a href="https://github.com/ewerspej/maui-samples" rel="nofollow noreferrer">Here is a sample repository</a> where the problem can be reproduced, just uncomment the following code block in the <em>MainActivity.cs</em> file:</p>
<pre class="lang-cs prettyprint-override"><code> protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
//#if ANDROID30_0_OR_GREATER
// if (Build.VERSION.SdkInt >= BuildVersionCodes.R) //R == API level 30.0
// {
// Window?.InsetsController?.Hide(WindowInsets.Type.SystemBars());
// }
//#endif
}
</code></pre>

74,165,517 | <p>I'm going to have about 7 states for my screen and want to navigate them in specific order using BottomNavigationBar with two items, of which first goes "back" and second one forth. Problem is, there's a default index for BottomNavigationBar, which is 0, and the first option is always higlighted. Is there a way to make it no highlighted, or maybe another widget that looks like BottomNavigationBar, that fits better with what I'm trying to do? I use BottomNavigationBar in my app already for other screen, and would like to maintain the similar look.</p>

<p>I have this right now (in Vue) which sorts an array of numbers from high to low, as it should.</p>
<p>What I instead need is a sorting function which does not look at negative numbers differently from positive numbers.</p>
<p>This is the output I would like (high to low):
[-531, 245, -195, 54, -12]</p>
<p>I'm getting:
[245, 54, -12, -195, -513]</p>

74,165,606 | <p>I'm trying to clone a specific branch (the "dev" branch) of a GitHub repository. With the git command I can run something like</p>
<pre><code>git clone --branch dev https://github.com/user/repo
</code></pre>
<p>What's the equivalent of this in <code>gh</code> (GitHub CLI)? I can't find it in the docs</p>

74,165,627 | <p>I'm trying to create settings page from json. But first i'm checking if creating is working on static array:</p>
<pre><code>import 'package:flutter/material.dart';
import 'package:settings_ui/settings_ui.dart';
class _SettingsScreenState extends State<SettingsScreen> {
bool lockInBackground = true;
@override
void initState() {
super.initState();
}
@override
Widget build(BuildContext context) {
var tilearray = [{'name':'settings no 1'},{'name':'settings no 2'},{'name':'settings no 3'}];
List<SettingsTile> tiles = [];
log('{$tilearray}');
tiles.add( SettingsTile.switchTile(
initialValue: lockInBackground,
onToggle: (bool value) {
setState(() {
lockInBackground = value;
});
},
leading: Icon(Icons.phonelink_lock),
title: Text('settings no 0')));
tilearray.map((item) => log('test{$item.name}'));
tilearray.map((item) => tiles.add( SettingsTile.switchTile(
initialValue: lockInBackground,
onToggle: (bool value) {
setState(() {
lockInBackground = value;
});
},
leading: Icon(Icons.phonelink_lock),
//title: Text(item['name']!))));
title: Text('debug item'))));
log('{$tiles}');
return Scaffold(
appBar: AppBar(title: Text('Settings UI')),
body: SettingsList(
sections: [
SettingsSection(
title: Text('First Section'),
tiles: tiles,
)
]
)
);
}
}
</code></pre>
<p>But the result is only one SettingsTile (Setting no 0)...</p>
<p>The comment I add to check if there's a problem with array item, but no. It looks like tilearray is empty.</p>
<p>It is strange that <code>tilearray.map((item) => log('test{$item.name}'));</code> is empty too</p>

74,165,629 | <p>In my Kubernetes cluster, I have a ConfigMap object containing the address of my Postgres pod. It was created with the following YAML:</p>
<pre><code>apiVersion: v1
kind: ConfigMap
metadata:
name: postgres-configmap
data:
database_url: postgres-service
</code></pre>
<p>Now I reference this value in one of my Deployment's configuration:</p>
<pre><code>env:
- name: DB_ADDRESS
valueFrom:
configMapKeyRef:
name: postgres-configmap
key: database_url
</code></pre>
<p>This deployment is a Spring Boot application that intends to communicate with the database. Thus it reads the database's URL from the DB_ADDRESS environment variable. (ignore the default values, those are used only during development)</p>
<pre><code>datasource:
url: ${DB_ADDRESS:jdbc:postgresql://localhost:5432/users}
username: ${POSTGRES_USER:postgres}
password: ${POSTGRES_PASSWORD:mysecretpassword}
</code></pre>
<p>So, according to the logs, the problem is that the address has to have the <code>jdbc:postgresql://</code> prefix. Either in the ConfigMap's YAML or in the application.yml I would need to concatenate the prefix protocol string with the variable. Any idea how to do it in yml or suggestion of some other workaround?</p>

74,165,636 | <p>I'm trying to map a lambda function to variable that can be a float, int, or list.</p>
<p><strong>Test #1</strong>, this works:</p>
<pre><code>val = [0.1]
test = list(map(lambda x: max(x, 1 - x), val))
</code></pre>
<p><strong>Test #2</strong>, this throws <code>TypeError: 'float' object is not iterable</code>:</p>
<pre><code>val = 0.1
test = list(map(lambda x: max(x, 1 - x), val))
</code></pre>
<p>I tried to solve it with <code>list(val)</code> (that is, <code>list(map(lambda x: max(x, 1 - x), list(val)))</code>), but it throws the same error.</p>
<p><strong>How can I get it to work in both Test #1 and Test #2?</strong> Python 3.7</p>

74,165,651 | <p>I want to position a div at the center of the screen. The issue is when the div is small, from left 45% looks fine but when the div is longer(ie more width), I need to make it from left 30%</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
