<p>I find myself doing this a lot, and I assume there is a short hand way to make this faster. Yet in my research about shorthand and ternary operations, I can't quite seem to wrap my head around how to do it.</p>
<pre><code>// below variable only be impactful if it's SET, not Null, and === important value.
$verbose_instructively_named_variable = $other_variable. "_modifier";
if(isset($verbose_instructively_named_variable) && $verbose_instructively_named_variable !== null && $verbose_instructively_named_variable === "key_text_modifier"):
// Now do important thing here;
endif;
</code></pre>
<p>I am a beginning programmer obviously, but find myself attracted to longer variable names so when I revisit things later it flows linearly for me. So I find myself wanting to do the below all the time, and am frustrated I can't.</p>
<pre><code>if(isset($verbose_instructively_named_variable) && !==null && === "key_text_modifier"):
// Now do important stuff;
endif;
</code></pre>
<p>I know this is a PHP question, but I find myself wanting this form of chained logic in javascript also. Am I missing a basic step of some kind?</p>
<p>Is there an altogether different way to test ONE variable for multiple conditions quickly and efficiently?</p>
<p>I have tried combinations of things found in similar questions. Like the in_array solution provided in this answer: <a href="https://stackoverflow.com/questions/16345833/in-php-is-there-a-short-way-to-compare-a-variable-to-multiple-values">In PHP, is there a short way to compare a variable to multiple values?</a></p>
<p>As well as things like the below standard shortcut/shorthand.</p>
<pre><code>$result = $initial ?: 'default';
</code></pre>
<p>But what I want often is something more like this.</p>
<pre><code>$result = ($initial !==null && !=="bad" && !in_array($initial,$record_set_from_mysql_query) ? $initial : 'default');
</code></pre>
<p>And keep in mind the main reason I don't like and don't want to do this:</p>
<pre><code>$result = ($initial !==null && $initial !=="bad" $initial !=="even_worse" ? $initial : 'default');
</code></pre>
<p>Is because "$initial" maybe named something like $always_make_this_value_green_when_blue_present or something otherwise cumbersome to type repeatedly and it makes the code hard to read later with multi-line parameters in the functions etc.</p>
<p>Presently my best work around for this is to do this.</p>
<pre><code>$a = $long_verbose_instructively_named_variable;
$result = $a !== null && $a !== "bad" && $a !== "even_worse" ? $a : 'default';
</code></pre>
<p>But this means in a function with a half dozen little small if/else checks I end up with a, aa, aaa, a_4, a_5 variables all over the place and it just gets cumbersome.</p>

<p>I have simple class like that;</p>
<pre><code>class Foo {
constructor() {
this.datas = {}
}
set(key, data) {
return this.datas[key] = data
}
get(key) {
return this.datas[key]
}
}
module.exports = Foo
</code></pre>
<p>I am adding some data to <code>datas</code> veriable first. But when I call same class in the next time, veriable is not saving like that;</p>
<pre><code>const foo1 = Foo()
foo1.set('a',[1,2,3])
const foo2 = Foo()
var aData = foo2.get('a')
console.log(aData)
</code></pre>
<p>But data not getting. How can I fix it?</p>

<p>I'm trying to decode a JSON string in swift but having some weird issues accessing the properties once decoded.</p>
<p>This is the contents of the JSON file that I retrieve from a locally stored JSON file</p>
<pre class="lang-json prettyprint-override"><code>[
{
"word": "a",
"usage": [
{
"partOfSpeech": "determiner"
}
]
}
]
</code></pre>
<p>And this is the code to access the properties of the JSON file</p>
<pre class="lang-swift prettyprint-override"><code>struct WordDictionary : Codable {
var word: String
var usage: [Usage]
}
struct Usage: Codable {
var partOfSpeech: String
}
if let url = Bundle.main.url(forResource: FILE_NAME, withExtension: "json") {
do {
let data = try Data(contentsOf: url)
let decoder = JSONDecoder()
let jsonData = try decoder.decode([WordDictionary].self, from: data)
print(jsonData[0].word) //Outputs "a"
print(jsonData[0].usage) //Outputs "[MyApp.AppDelegate.(unknown context at $102a37f00).(unknown context at $102a38038).Usage(partOfSpeech: "determiner")]"
} catch {
print("error:\(error)")
}
}
</code></pre>
<p>As you can see, when I try to <code>print(jsonData[0].usage)</code> I get a series of unknown data messages before I get the “Usage” property. When I print this line I just want to see <code>determiner</code>, I’m not sure what the preamble about the “unknown context” is all about.</p>
<p>I’m also running this code in <code>didFinishLaunchingWithOptions</code> function of the <code>AppDelegate</code>.</p>
<p>I’m not sure what I’m missing. I've been trying to find a solution for a few days now and trying different approaches but still can’t get the desired output, any help would be appreciated.</p>

<p>I am trying to have 9 columns per row using <code>row-cols-*</code>, but it doesn't work with more than 6:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code><script src="https://cdn.jsdelivr.net/npm/bootstrap@5.2.3/dist/js/bootstrap.bundle.min.js"></script>

<p>How can I use more than 6? I need 9 in my case. I thought I could have up to 12.</p>

<p>I am in the process of creating a web application for a genealogy project. I want each person I add onto the database to have a unique id, based on the first 3 characters of their surname (let's call it, for the purpose of explaining, 'surname-string'), concatenated with an autoincrement (which starts from 00001 for each unique 'surname-string').</p>
<p>For example - a person's surname is "Smith". The surname-string will be SMI and due to the fact that they are the first surname-string "SMI" the full reference will be SMI00001. Another person's surname is Black, making their surname-string BLA, and because they are the first one with the surname-string BLA, their reference will be BLA00001. A third person's surname is also Smith - they are the second person with the SMI surname-string, so their reference should be SMI00002.</p>
<p>This unique id will be used in the persons URL, to be searched by and create relationships between people in the database.</p>
<p>I have no clue how to approach this logically.</p>
<p>I have not tried anything yet. It goes way over my head!</p>

<p>I am trying to write a multi-threaded program to produce a vector of <code>N*NumPerThread</code> uniform random integers, where <code>N</code> is the return value of <code>std::thread::hardware_concurrency()</code> and <code>NumPerThread</code> is the amount of random numbers I want each thread to generate.</p>
<p>I created a multi-threaded version:</p>
<pre><code>#include <iostream>
#include <thread>
#include <vector>
#include <random>
#include <chrono>
using Clock = std::chrono::high_resolution_clock;
namespace Vars
{
const unsigned int N = std::thread::hardware_concurrency(); //number of threads on device
const unsigned int NumPerThread = 5e5; //number of random numbers to generate per thread
std::vector<int> RandNums(NumPerThread*N);
std::random_device rd;
std::mt19937 gen(rd());
std::uniform_int_distribution<> dis(1, 1000);
int sz = 0;
}
using namespace Vars;
void AddN(int start)
{
static std::mutex mtx;
std::lock_guard<std::mutex> lock(mtx);
for (unsigned int i=start; i<start+NumPerThread; i++)
{
RandNums[i] = dis(gen);
++sz;
}
}
int main()
{
auto start_time = Clock::now();
std::vector<std::thread> threads;
threads.reserve(N);
for (unsigned int i=0; i<N; i++)
{
threads.emplace_back(std::move(std::thread(AddN, i*NumPerThread)));
}
for (auto &i: threads)
{
i.join();
}
auto end_time = Clock::now();
std::cout << "\nTime difference = "
<< std::chrono::duration<double, std::nano>(end_time - start_time).count() << " nanoseconds\n";
std::cout << "size = " << sz << '\n';
}
</code></pre>
<p>and a single-threaded version</p>
<pre><code>#include <iostream>
#include <thread>
#include <vector>
#include <random>
#include <chrono>
using Clock = std::chrono::high_resolution_clock;
namespace Vars
{
const unsigned int N = std::thread::hardware_concurrency(); //number of threads on device
const unsigned int NumPerThread = 5e5; //number of random numbers to generate per thread
std::vector<int> RandNums(NumPerThread*N);
std::random_device rd;
std::mt19937 gen(rd());
std::uniform_int_distribution<> dis(1, 1000);
int sz = 0;
}
using namespace Vars;
void AddN()
{
for (unsigned int i=0; i<NumPerThread*N; i++)
{
RandNums[i] = dis(gen);
++sz;
}
}
int main()
{
auto start_time = Clock::now();
AddN();
auto end_time = Clock::now();
std::cout << "\nTime difference = "
<< std::chrono::duration<double, std::nano>(end_time - start_time).count() << " nanoseconds\n";
std::cout << "size = " << sz << '\n';
}
</code></pre>
<p>The execution times are more or less the same. I am assuming there is a problem with the multi-threaded version?</p>
<p>P.S. I looked at all of the other similar questions here, I don't see how they directly apply to this task...</p>

<p>If I have a dataframe `</p>
<pre><code>A Variant&Price Qty
AAC 7:124|25: 443 1
AAD 35:|35: 1
AAS 32:98|3:40 1
AAG 2: |25: 1
AAC 25:443|26:344 1
</code></pre>
<p>and I want to get variant which has one of its values is below 7</p>
<pre><code>A Variant&Price Qty
AAC 7:124|25: 443 1
AAS 32:9|3:40 1
AAG 2: |25: 1
</code></pre>
<p>Note that first digit is the variant, as well as the third digit (variant always before <code>:</code>)
I can apply this code,</p>
<pre><code>split_df = df['Variant&Price'].str.split(':|\|', expand=True)
print(df[split_df.iloc[:, [0,2]].astype(int).min(axis=1) <= 7])
</code></pre>
<p>But what if I want to get, instead of 7, it is now range from 2 to 7. I ve tried <code>>=2 & <=7</code> but not working</p>

<p>Inside one JS file I saw:</p>
<pre><code>Math.round(timeEngine.timeLeft, 10)
</code></pre>
<p>I've checked many documentations (some are mentioned here) and all mention that this function takes one argument, so what the second argument (10) is referring to?</p>

<p>Here's the code that I attempted</p>
<pre><code>public String isPalindrome(String s) {
String trimmed = s.replaceAll("[^A-Za-z0-9]", "");
String reversed = "";
int len = trimmed.length();
for (int i = len - 1; i >= 0; i--) {
char[] allChars = trimmed.toCharArray();
reversed += allChars[i];
}
if (trimmed.equalsIgnoreCase(reversed)) {
return "true";
} else {
return "false";
}
}
</code></pre>
<p>Sample Input 1
A man, a plan, a canal: Panama</p>
<p>Sample Output 1
true</p>
<p>Explanation 1
The given string is palindrome when considering only alphanumeric characters.</p>
<p>Sample Input 2
race a car</p>
<p>Sample Output 2
false</p>
<p>Explanation 2
The given string is not a palindrome when considering alphanumeric characters.</p>

<p>I want to merge two arrays.
I want to get arr1 data based on arr2 structure, how should I do it?</p>
<p>I tried using 3 forEach, but it doesn't work.</p>
<pre><code>const arr1 = [{id:'1', List:[{name:'a', title:'a title'}, {name:'b', title:'b title'}]}, {id:'2', List:[{name:'c', title:'c title'}, {name:'d', title:'d title'}]}];
const arr2 = [{id:'1', name:'a'}, {id:'1', name:'b'}, {id:'2', name:'c'}];
</code></pre>
<p>I want the result below</p>
<pre><code>newArr = [{id:'1', List:[{name:'a', title:'a title'}, {name:'b', title:'b title'}]}, {id:'2', List:[{name:'c', title:'c title'}]}]

<p>The calculator should take inputs like (23>3) or (a>9) and prints if it's true or false. My main difficulty is doing it for letters. I only managed to do it for numbers. I don't know how to define the <code>scanf</code> to accept a letter. When a letter is compared to a number, I need to compare the letters' ASCII values. So, if I do <code>a>9</code> it actually checks if <code>97>9</code> (97 is the ASCII value of 'a').</p>
<pre><code>#include <stdio.h>
int main() {
int num1, num2;
char operator;
printf("Please write your logical statement:");
scanf("%d %c %d", &num1, &operator, &num2);
if (operator=='>')
{
if (num1>num2)
{
printf("True");
}
else
{
printf("false");
}
}
else if (operator =='<')
{
if (num1<num2)
{
printf("True");
}
else
{
printf("false");
}
}
else if (operator == '=')
{
if (num1==num2)
{
printf("True");
}
else
{
printf("False");
}
}
}
</code></pre>
<p>How do I modify it to also accept characters?</p>

<p>I am using a Stanford STANZA pipeline on some (italian) text.</p>
<p>Problem I'm grappling with is that I need data from BOTH the Token and Word objects.</p>
<p>While I'm able to access one or the other separately I'm not wrapping my head on how to get data from both in a single loop over the Document -> Sentence</p>
<p>Specifically I need both some Word data (such as lemma, upos and head) but I also need to know the corresponding start and end position, which in my understanding I can find in the token.start_char and token.end_char.</p>
<p>Here's my code to test what I've achieved:</p>
<pre><code>import stanza
IN_TXT = '''Il paziente Rossi e' stato ricoverato presso il nostro reparto a seguito di accesso
al pronto soccorso con diagnosi sospetta di aneurisma aorta
addominale sottorenale. In data 12/11/2022 e' stato sottoposto ad asportazione dell'aneurisma
con anastomosi aorto aortica con protesi in dacron da 20mm. Paziente dimesso in data odierna in
condizioni stabili.'''
stanza.download('it', verbose=False)
it_nlp = stanza.Pipeline('it', processors='tokenize,lemma,pos,depparse,ner',
verbose=False, use_gpu=False)
it_doc = it_nlp(IN_TXT)
# iterate through the Token objects
T = 0
for token in it_doc.iter_tokens():
T += 1
token_id = 'T' + str((T))
token_start = token.start_char
token_end = token.end_char
token_text = token.text
print(f"{token_id}\t{token_start} {token_end} {token_text}")
# iterate through Word objects
print(*[f'word: {word.text}\t\t\tupos: {word.upos}\txpos: {word.xpos}\tfeats: {word.feats if word.feats else "_"}' for sent in it_doc.sentences for word in sent.words], sep='\n')
</code></pre>
<p>Here is the documentation of these objects: <a href="https://stanfordnlp.github.io/stanza/data_objects.html" rel="nofollow noreferrer">https://stanfordnlp.github.io/stanza/data_objects.html</a></p>

<p>I'm trying to clear values in the sheets that are present in a workbook. I have a list of all possible (valid) sheets, but I won't know which sheet is currently present in the workbook. So, I need to get the worksheets' name, see if it's valid and then clear its contents. Here's what I have so far:</p>
<pre><code>Sub testclear()
Dim validsheets() As Variant, sheetstoclear() As Variant
Dim i as Integer, j As Integer, k As Integer, m as Integer
validsheets() = Array ("Sheet1", "Sheet2", "Sheet3", "Sheet4", "Sheet5")
For i = 1 To Worksheets.count
For j = LBound(validsheets) to UBound(validsheets)
If Worksheets(i).Name = validsheets(J) Then
sheetstoclear(k) = Worksheets(i).Name
k = k +1
End If
Next j
Next i
For m = LBound(sheetstoclear) to UBound(sheetstoclear)
Sheets(sheetstoclear(m+1)).Cells.clear
Next m
End Sub
</code></pre>
<p>If I execute the above code, I get the following error -</p>
<pre><code>Run-time error'9':
Subscript out of range
</code></pre>

<p>I want to call a component and render it once on button click. So if I pressed the button again it would render however does not constantly try and re render itself.</p>
<p>At the moment, I am passing a function to the component and calling at the end of the useEffect. However this seems to not render anything.</p>
<p>Here is what I have in my App.js</p>
<pre><code>function App() {
const [open, setOpen] = React.useState(false);
const [dataFormat, setDataFormat] = React.useState("");
const openData = () => {
setOpen(true);
};
const closeData = () =>{
setOpen(false);
}
const changeDataFormat = (selectedOption) => {
console.log(selectedOption);
setDataFormat(selectedOption);
};
return (
<main className="App">
<h1>Film Management</h1>
<SelectDataFormat changeDataFormat={changeDataFormat} />
<button onClick={openData}>Show Films</button>
<table border="1">
<thead>
<tr>
<th>Title</th>
<th>Year</th>
<th>Director</th>
<th>Stars</th>
<th>Review</th>
</tr>
</thead>
<tbody>{open && <FilmTableRows closeData={closeData} dataFormat={dataFormat} />}</tbody>
</table>
</main>
);
}
</code></pre>
<p>And this is the component I want to render</p>
<pre><code>
function FilmTableRows(props) {
const convert = require("xml-js");
const dataFormat = props.dataFormat;
const [filmList, setFilmList] = useState([]);

.then((res) => {

})
.catch((err) => {});

<p>I would like to be able to call class prototype methods using bracket notation, so that the method name can be decided at run time:</p>
<pre class="lang-js prettyprint-override"><code>classInstance['methodName'](arg);
</code></pre>
<p>I am failing to do this properly with TypeScript:</p>
<pre class="lang-js prettyprint-override"><code>class Foo {
readonly ro: string = '';
constructor() {}
fn(s: number) { console.log(s); }
}
const foo = new Foo();
const methods = ['fn'];
foo['fn'](0)
// Type 'undefined' cannot be used as an index type.
foo[methods[0]](1);
// This expression is not callable.
// Not all constituents of type 'string | ((s: number) => void)' are callable.
// Type 'string' has no call signatures.
foo[methods[0] as keyof Foo](1);
</code></pre>
<p>The above example is in the <a href="https://www.typescriptlang.org/play?noUncheckedIndexedAccess=true&noPropertyAccessFromIndexSignature=false#code/MYGwhgzhAEBiD29oG8BQ1oCcCmYAm8AdiAJ5bwBc0EALpgJaEDm0AvNAOQcDc60wRWpgCuwGvEwAKAJQoAvnwBmhSRCqFhAWwBG2TLOT9B8ENgB0IeE1XTu0BQtQDCtaIsRtohbAHc4iGV5nV01sGgALeDwYdgBtDmUOAF1eVHd4eMSkyQAGaVRUAHpC6AAVEgAHbE5hQjxsRUZsPA5+MEJCeBpoXWhhCGboSCHCaEZ6gA9oGkrzNMRY0IioiFicpOyARlsC4rLw+hhsCYqcKHoiMZhO7uAwEHBtUzMikoA5LqGHoxcaehphNhCDQYPBFNNZpwhIwWAAfaCSVTqLS6fRsAB80AAbvB6HhpK0wDg2g8wE85ntylUoXQYa1wsNOiSQNR6ExCGAAWcXulFmFItE1kkhjAANbYEhg-zwLa2IA" rel="nofollow noreferrer">TS Playground</a>.</p>
<p>I think that I have a reasonable understanding of what the errors mean and why the string literal in <code>foo['fn'](0)</code> does not produce an error. However, I don't understand how to prevent the errors. I thought that I might be able to use <a href="https://www.typescriptlang.org/docs/handbook/utility-types.html#extracttype-union" rel="nofollow noreferrer">Extract</a> to build a type comprising of Function, but I've failed to do that.</p>
<p>How can I produce a list of typed method names over which my code can iterate? And better, is it possible for the class to export such a list so that users of the class can easily access them?</p>
<p><strong>Background Information</strong></p>
<p>I have a <a href="https://playwright.dev/" rel="nofollow noreferrer">Playwright</a> test that needs to iterate over a list of methods from a <a href="https://playwright.dev/docs/pom" rel="nofollow noreferrer">Page Object Model</a>, producing a screenshot for each.</p>

<p>Julia REPL tells me that the output of</p>
<pre><code>'c'+2
</code></pre>
<p>is <code>'e': ASCII/Unicode U+0065 (category Ll: Letter, lowercase)</code>
but that the output of</p>
<pre><code>'c'+2-'a'
</code></pre>
<p>is <code>4</code>.</p>
<p>I'm fine with the fact that Chars are identified as numbers via their ASCII code. But I'm confused about the type inference here: why is the first output a char and the second an integer?</p>

<p>I have sales data that gives me dates in a bad format. Every new sale gets automatically added to the sheet. Looks like this:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Column A</th>
<th>Column B</th>
<th>Column C</th>
</tr>
</thead>
<tbody>
<tr>
<td>Order 1</td>
<td>2022-12-02T02:09:37Z</td>
<td>$1025.19</td>
</tr>
<tr>
<td>Order 2</td>
<td>2022-12-02T01:25:15Z</td>
<td>$873.65</td>
</tr>
</tbody>
</table>
</div>
<p>This will continue on for all sales. Now the date format is UTC for whatever reason and I can't adjust that, so within this formula I have to subtract 6 hours to get it to central time. I'm trying to create an auto-updating chart that shows an average day for 7 days, so I'm trying to do a sumif formula.</p>
<p>Here's what I have on Sheet2:</p>
<pre><code>=sumif(Sheet1!C:C,index(split((index(split(Sheet1!B:B,"T"),1)+index(split(left(Sheet1!B:B,19),"T"),2))-0.25,"."),1),A1)
</code></pre>
<p>Where A1 is a single date. Testing this with one date and not the range shows that it does match. When I do the range, the total comes to 0, even though multiple different dates should match. What am I doing wrong?</p>

<p>Have this so far, and essentially want to get there is something wrong with the position of <code>last_odd</code> as the compiler says the pop index is out of range?</p>
<pre><code>def remove_last_odd(numbers):
has_odd = False
last_odd = 0
for num in range(len(numbers)):
if numbers[num] % 2 == 1:
has_odd = True
last_odd = numbers[num]
if has_odd:
numbers.pop(last_odd)
numbers = [1, 7, 2, 34, 8, 7, 2, 5, 14, 22, 93, 48, 76, 15, 6]

<p>I need to write a JavaScript program where it validates input.</p>
<p>Requirement:</p>
<ul>
<li>Input will have a specific prefix. (eg: --NAME--)</li>
<li>After this prefix, there can be any characters. (eg:
--NAME--any-name_wit#-any*_special_char@#$%)</li>
<li>Minimum length of total input (or length of suffix) should be 50 (for example)</li>
</ul>
<p>I was able to write regex for the first two points, but I couldn't include the final point.
here is what I have tried for the first two points.</p>
<pre><code>input.match(^--NAME--(.*)$)
</code></pre>

<p>I think I remember something like this from python, maybe it was the walrus operator? idk.</p>
<p>but is there a way to set an attribute while returning the value? something like this:</p>
<pre><code>class Foo {
late String foo;
Foo();
String setFoo() => foo := 'foo';
}
f = Foo();
x = f.setFoo();
print(x);
// 'foo'
</code></pre>

<p>I know similar questions exist.</p>
<p>I've gone through most of them but, so far, none of the solutions worked.</p>
<p>Here is the context:</p>
<p>Operating system: <strong>macOS Ventura 13.0.1</strong> (Intel processor)</p>
<p>Here are some commands output:</p>
<pre><code>$ ruby -v
ruby 2.7.5p203 (2021-11-24 revision f69aeb8314) [x86_64-darwin22]
$ which ruby
/Users/..../.rbenv/shims/ruby
$ bundler -v
Bundler version 2.3.26
$ which bundler
/Users/..../.rbenv/shims/bundler
</code></pre>
<p>My <strong>~/.bash_profile</strong> and <strong>~/.zshrc</strong> contain:</p>
<pre><code>export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
export PATH="$HOME/.rbenv/shims:$PATH"
eval "$(rbenv init -)"
</code></pre>
<p>I know nothing about <strong>ruby</strong>, I'm using <code>rbenv</code> to manage <strong>ruby</strong> versions.</p>
<p>I've done a similar setup on another macOS system but for some reason, on this system, nothing I have tried works.</p>
<p>Any helps is appreciated.</p>
<p>Thanks.</p>

<p>I am running WSL2 and trying to get Git Credential Manager (GCM) set up so that I don't have to always copy-paste my Github Personal Access Token into my terminal. Once I added the credential manager I was unable to access my remote repositories, this is what my <code>.gitconfig</code> looks like:</p>
<pre><code> 1 [user]
1 email = myemail@gmail.com
2 name = Name
3 [credential]
4 helper = /mnt/c/Program\\ Files/Git/mingw64/libexec/git-core/git-credential-wincred.exe
</code></pre>
<p>Now when I do a <code>git pull</code> on the remote repository Git is telling me that it cannot be found. It's not clear to me why GCM is blocking me now, but would you have any recommendations for next steps?</p>

<p>I was wondering regarding Kubernetes HPA custom metrics HPA how it is calculated with targetAverageValue.
If for example I’m using the metric that scales pods based on the number of nginx request then each pod now have is own specific metric and I was wondering if it takes each pod and check regarding its value or if it takes all of their metrics and divide this by the number of the pods?</p>

<p>I'm using MudBlazor component library. In order to show loading on form buttons, the <a href="https://mudblazor.com/components/button#loading-button" rel="nofollow noreferrer">documentation</a> guides like this:</p>
<pre><code><MudButton Disabled="@_processing" OnClick="ProcessSomething" Variant="Variant.Filled" Color="Color.Primary">
@if (_processing)
{
<MudProgressCircular Class="ms-n1" Size="Size.Small" Indeterminate="true"/>
<MudText Class="ms-2">Processing</MudText>
}
else
{
<MudText>Click me</MudText>
}
</MudButton>
</code></pre>
<p>Now since I'm doing this a lot, I wanted to wrap this logic inside another component.</p>
<p>The following component does not do the job:</p>
<pre><code>@inherits MudButton
@code {
bool _loading;
[Parameter]
public bool Loading
{
get => _loading;
set
{
_loading = value;
Disabled = value;
}
}
[Parameter]
public new RenderFragment ChildContent
{
get => base.ChildContent;
set => base.ChildContent = ExtendContent(value);
}
private RenderFragment ExtendContent(RenderFragment baseContent) => __builder =>
{
if (Loading)
{
<MudProgressCircular Class="ms-n2" Size="Size.Small" Indeterminate="true" />
}
@baseContent
};
}
</code></pre>
<p>I get this error:</p>
<blockquote>
<p>The type '<my_component>' declares more than one parameter matching
the name 'childcontent'. Parameter names are case-insensitive and must
be unique.</p>
</blockquote>

<p>AI also wrote a model like this:</p>
<pre><code>List <School> schools = [];
List<School> allSchools() {
return schools;
}
class School {
String city;
String districty;
String name;
School({required this.city, required this.name, required this.districty});
}
</code></pre>
<p>How can I export data from JSON to list? So I want to pass it like this:</p>
<pre><code>List <School> schools = [
School(city: "ISTANBUL", districty: "Kagithane", name: "Kagithane anadolu lisesi"),
School(city: "ISTANBUL", districty: "Sisli", name: "Aziz Sancar anadolu lisesi"),
School(city: "IZMIR", districty: "ADALAR", name: "Kemal Sunal anadolu lisesi"),
School(city: "ISTANBUL", districty: "BAGCILAR", name: "Bagcilar Fen lisesi"),
School(city: "ISTANBUL", districty: "Kagithane", name: "Kagithane Meslek lisesi")
];

<p>I appreciate your help in advance, thanks.</p>

<p>Note, if it is single element I can extract but I need to extract all of them together.</p>
<p>Hi I am trying to extract the text and link from a list of items from a page using Selenium and Java. I am able to extract all link text but facing issue to figure out the link text. The html code looks like below:</p>
<pre><code><div class="col-12">
<a href="/category/agricultural-products-service">
<img src="/assets/images/icon/1.jpg" alt="icon" class="img-fluid category_icon">
<h5 class="category_title">Agricultural </h5>
</a>
</div>
<div class="col-12">
<a href="/category/products-service">
<img src="/assets/images/icon/7.jpg" alt="icon" class="img-fluid category_icon">
<h5 class="category_title">Products</h5>
</a>
</div>
</code></pre>
<p>Using <code>h5</code> I can extract all the elements but I need to extract all href of those elements</p>

<p>I am trying to control the input I took from a form with joi validation. The function <code>validateCampgrount</code> is a middleware to check it but when I try to write the next function it says next is not defined.*</p>

<pre><code>const validateCampground = (req, res, next) => {
const { error } = campgroundSchema.validate(req.body);

throw new ExpressError(msg, 400);

next();

<p>I had given a technical interview in which I have been asked to find intersection point of n link list.
I could come up to find intersection point of 2 link list but couldn't extend it.
Could someone help me reach the algorithm</p>
<p>I tried to call the function to find integration point of 2 link list for every pair, but that didn't work.</p>

<p>This is a follow up on <a href="https://stackoverflow.com/questions/74667477/no-user-defined-conversion-when-using-standard-variants-and-visitor-pattern/74667677#74667677">No user defined conversion when using standard variants and visitor pattern</a></p>
<p>I need to implement a <strong>templated version</strong> of the <a href="https://en.wikipedia.org/wiki/Visitor_pattern" rel="nofollow noreferrer">visitor pattern</a> as shown below, however it looks like the <code>accept</code> function has to be virtual which is not possible. Could you please help me?</p>
<pre><code>#include <variant>
#include <iostream>
class Visitable //I need this to be non-templated (no template for Visitable!!): Otherwise I could use CRTP to solve this issue.
{
public:
virtual ~Visitable() = default;

visitable.accept(&visitor);
//I want to be doing this:
Visitable* doubleV = new DoubleVisitable();
doubleV->accept(&visitor);
delete doubleV;
return 1;
}
</code></pre>
<p>The code is here <a href="https://godbolt.org/z/4e4K54dbv" rel="nofollow noreferrer">Link</a>. Could you please help me make this not throw but collapses to the right child class <code>DoubleVisitable</code> or <code>StringVisitable</code>. It looks like I need virtual templated member function which is not possible as mentioned here <a href="https://stackoverflow.com/questions/2354210/can-a-class-member-function-template-be-virtual">Can a class member function template be virtual?</a></p>

<p>I want to use a python script to call it in the <strong>pam_exec</strong> module.</p>
<p>The <a href="https://stackoverflow.com/questions/53820496/using-my-own-python-script-to-authenticate-into-my-computer">first answer</a> in this question says that I can't use a python script and a PAM module together.</p>
<blockquote>
<p>First off - you cannot use python code as a PAM module, it has to be compiled code that satisfies certain interface requirements. See here for more info.</p>
</blockquote>
<p><a href="https://man7.org/linux/man-pages/man8/pam_exec.8.html" rel="nofollow noreferrer">Here</a> we are clearly given to understand that pam_exec is a PAM module.</p>
<blockquote>
<p>pam_exec - PAM module which calls an external command</p>
</blockquote>
<p>So is it possible to use python or not? (This also applies to my <a href="https://stackoverflow.com/questions/74668478/how-do-i-get-variables-from-a-python-script-that-are-visible-in-the-sh-script">previous question.</a>)</p>

<p>I have a script running that reformats borders on a variable range on the active sheet.
I would like to have it cycle through other sheets in the same workbook, without those changes being visible to the user (ie - the GUI of the current screen stays as the only thing visible while the script runs).</p>
<p>Currently each sheet is displayed as it loops and performs the reformat. How can I keep the initial sheet visible, and have the script run in the background? Obviously it is the use of ".setActiveSheet" and ".getActiveSheet" causing this.</p>
<p>Still pretty new at all this, so any suggestions to otherwise cleanup/condense/speed up greatly appreciated.</p>
<pre><code>function allBorders(){
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var ss = SpreadsheetApp.getActiveSheet();
var sheetname = ss.getSheetName();
var range;
var headrows = 3;
var lr = ss.getLastRow() //last row with data
var lc = ss.getLastColumn()
var mr = ss.getMaxRows() //max possible rows
var ns = SpreadsheetApp.getActiveSpreadsheet().getNumSheets()
Logger.log("Number of sheets: "+ns)
for (var i = 0; i < ns; i++){
Logger.log("i value: "+i)
spreadsheet.setActiveSheet(spreadsheet.getSheets()[i]);
sheetname = spreadsheet.getSheetName();
Logger.log("Sheetname: "+sheetname)
switch(sheetname){
case "Openings":
ss = SpreadsheetApp.getActiveSheet();
headrows = 6;
lr = ss.getLastRow() //last row with data
lc = ss.getLastColumn()
mr = ss.getMaxRows() //max possible rows
break;
case "My Trips":
ss = SpreadsheetApp.getActiveSheet();
headrows = 6;
lr = ss.getLastRow() //last row with data
lc = ss.getLastColumn()
mr = ss.getMaxRows() //max possible rows
break;
case "All_Trips":
ss = SpreadsheetApp.getActiveSheet();
headrows = 6;
lr = ss.getLastRow() //last row with data
lc = ss.getLastColumn()
mr = ss.getMaxRows() //max possible rows
break;
default:
break;
}
range = ss.getRange((1+headrows),1,mr,lc) //clear all rows below header
range.setBorder(false,false,false,false,false,false);
range = ss.getRange((1+headrows),1,(lr-headrows),lc) //border active rows
range.setBorder(true, true, true, true, true, true);

<p>Please I am trying to plot a scatter plot as shown in the attached image.</p>
<p>I have tried the below code but it is not working. This is in python by the way.</p>
<pre><code>hours = [n / 3600 for n in seconds]
fig, ax = plt.subplots(figsize=(8, 6))
## Your code here
ax.plot(hours, fish_counts, marker="x")
ax.set_xlabel("Hours since low tide")
ax.set_ylabel("Jellyfish entering bay over 15 minutes")
ax.legend()[![enter image description here][1]][1]
</code></pre>
<p>Attached image is how the output should look. Thank you.

<p>I'm trying to add a custom field in Word (in the shape { CUSTOM_FIELD } ) that uses the current page number and outputs its text representation (12 => twelve), but in multiple exotic (not supported) languages, which is why the built-in English variant (page * cardtext) isn't sufficient.</p>
<p>The VBA code won't be a problem, but I need to know how to create a custom field.</p>
<p>The field would be added to the footer template, before 100s of pages would be added programmatically.</p>
<p>I tried using a custom DocProperty, but wasn't able to find a way to integrate the needed behavior. Another linked answer seems to be using the existing { PAGE } field, which wouldn't help, as I need to insert the new field (once only) into the footer template.</p>

<p>I have a data file that consists of a calorie count.
the calorie count it separated by each elf that owns it and how many calories are in each fruit.
so this represents 3 elves</p>
<pre><code>4323
4004
4070
1780
5899
1912
2796
5743
3008
1703
4870
5048
2485
1204
30180
33734
19662
</code></pre>
<p>all the numbers next to each other are the same elf. the separated ones are seperate.</p>
<p>i tried to detect the double line break like so</p>
<pre><code>import java.util.*;
import java.io.*;
public class Main
{
public static void main(String [] args) throws FileNotFoundException
{
int[] elf = new int[100000];
int cnt = 0;
Scanner input = new Scanner(new File("Elf.dat"));
while(input.hasNext())
{
elf[cnt] += input.nextInt();
if (input.next().equals("\n\n"));
{
cnt++;
}
}
int big = elf[0];
for (int lcv = 0; lcv < elf.length; lcv++)
{
if (big < elf[lcv])
{
big = elf[lcv];
}
}
System.out.println(big);
}
}
</code></pre>
<p>I'm trying this to detect the double line break</p>
<pre><code>if (input.next().equals("\n\n"));
</code></pre>
<p>but its giving me errors. how would i detect it</p>

<p>I have a function that prints the first multiples of a number (n) starting with zero and stopping at num_multiples, but it keeps printing out one too many multiples. I'm hoping someone can explain what I'm doing wrong so I can understand recursion a bit more.</p>
<pre><code>def print_first_multiples(n, num_multiples):
if num_multiples < 0:
return
else:
print_first_multiples(n, num_multiples - 1)
print(n * num_multiples, end=' ')
</code></pre>
<p>for example, passing 5 as n and 10 as num_multiples, it should print:
<code>0 5 10 15 20 25 30 35 40 45</code></p>
<p>but is instead printing an extra "50" at the end.</p>

<p>I have a component where-in I need to fetch some data and render it. The component gets rendered initially. The problem I'm facing is when the handler function <code>switchDocumentType</code> is called after clicking the button for a particular type, the whole component gets unmounted/un-rendered.</p>
<p>While debugging on my own I found this happens after <code>setDocumentType</code> is run inside event handler function.
What is wrong in the below code snippet that could possibly cause this issue? I can see the <code>useEffect</code> is not going in infinite-loop as well.</p>
<p>Code snippet:</p>
<pre class="lang-js prettyprint-override"><code>import * as React from 'react';
const MyComponent = (props) => {
const [documentType, setDocumentType] = React.useState('alpha');
const [documentData, setDocumentData] = React.useState('');
const types = ['alpha', 'beta', 'gamma'];
React.useEffect(() => {
myDataFetch('https://example.com/foo/?bar=123').then(async (response) => {
const data = await response.json();
setDocumentData(data.terms); // html string
const myDiv = document.getElementById('spacial-div');
myDiv.innerHTML = data; // need to render raw HTML inside a div
});
}, [documentType]);
const switchDocumentType = (type) => {
setDocumentType(type);
// send some analytics events
};
const convertToPDF = () => {
// uses documentData to generate PDF
};
return (
<div className="container-div">
{types.map((type) => {
return (
<button key={type} onClick={(type) => switchDocumentType(type)}>
{type}
</button>
);
})}
<div id="special-div" />
</div>
);
};
export default MyComponent;
</code></pre>

<p>I am implementing a simple arithmetic calculation on a server which includes add, sub, mul and Div, for the simplicity purposes no other operations are being done and also no parentheses "()" to change the precedence. The input I will have for the client is something like "1-2.1+3.6*5+10/2"(no dot product, 2.1 or 3.6 is a floating number). I have created a function to send the operands and operators but at a time I can send udp message of 1 computation in the format of (num1,op,num2)</p>
<pre><code>import struct
import socket
ip = "127.0.0.1"
port = 11200
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, 0) #creating socket
print("Do Ctrl+c to exit the program !!")
def sendRecv( num1, op, num2):
#sending udp message with num1,op and num
#receiving udp message with the result as res
res = s.recieve()
return res
sendRecv(in1, in_op, in2)
</code></pre>
<p>I was able to split the operators and operands using the regular split and separated them like</p>
<p>str = ['1', '-', '2.1', '+', '3.6', '*', '5', '+', '10', '/', '2']</p>
<p>since the multiplication and the division takes precedence over addition and subtraction (3.6, *, 5) should be sent first followed by the division, I am trying to write a while loop with while(len(str>0)), I am trying to understand how I can send multiplication first, store the intermediate result in the list itself and do a recurring function till all the computations are sent through message. I am not allowed to perform ny operation on client side, I can only send values to "SendRecv()". Any suggestions or ideas on how to proceed will be helpful.</p>
<p>Thanks in advance</p>

<p>I am wondering whether there is a difference in performance between these two if-statements:</p>
<pre class="lang-cs prettyprint-override"><code>if(myObject != null && myObject.someBoolean)
{
// do something
}
if (myObject?.someBoolean ?? false)
{
// do something
}
</code></pre>
<p>If there is a difference in performance, in favor of which approach and why?</p>
<p><strong>Edit:</strong>
This is not a bottleneck in my application, I am not trying to over-optimize, I am simply curious.</p>

<p>I am trying to use the fold operation on a range returned by <code>byLine()</code>. I want the lambda which is passed to fold to be a multi-line function. I have searched google and read the documentation, but cannot find a description as to what the signature of the function should be. I surmize that one of the pair is the accumulated sum and one is the current element. This is what I have but it will not build</p>
<pre><code>
auto sum = File( fileName, "r" )
.byLine
.fold!( (a, b)
{
auto len = b.length;
return a + len;
});
</code></pre>
<p>The error I get back from dmd is:</p>
<pre><code>main.d(22): Error: no property `fold` for `(File(null, null)).this(fileName, "r").byLine(Flag.no, '\n')` of type `std.stdio.File.ByLineImpl!(char, char)`
</code></pre>
<p>So my question is two fold:</p>
<ol>
<li>Is my use of fold in this case valid?</li>
<li>How do I pass a curley brace lambda to fold?</li>
</ol>
<p>I have tried searching google and reading the dlang documentation for fold. All documentation uses the shortcut lambda syntax <code>(a, b) => a + b</code>.</p>

<p>I have this kind of code</p>
<pre><code>typedef struct {
int x;
int y;
} Test;
Test* getTest(int *length) {
Test *toReturn = malloc(sizeof(Test));
// Some operations with realloc
return toReturn;
}
void printTest(Test *arrTest, int length) {
for(int i = 0; i < length; i++) {
// Some operations
}
}
int main() {
int testlength = 0;
Test *myTest = getTest(&testlength);
printTest(myTest, testLength) // Gives random numbers
}
</code></pre>
<p>Don't know why it gives random numbers, when I'm in the main tho (the whole code) it does not give these kinds of errors</p>

<p>in my C99-programme I want to use pseudo-random numbers between 0 an 1.
Unfortunatly, my programme always generates a first number that is almost identical. It just steps up ever so slightly every time I rerun my programme.</p>
<p>This is the relevant part of my programme:</p>
<pre><code>srand(time(NULL));
for(int i = 0; i < 10; i++){
float a = (float)rand()/RAND_MAX;
printf("%f\n",a);
</code></pre>
<p>And here are the results of two Iterations with a time difference of below 10 seconds:</p>
<pre><code>0.717103
0.357464
0.903628
0.271930
0.327478
0.917489
0.231215
0.026307
0.135259
0.290941
0.717221
0.330531
0.237708
0.151682
0.318986
0.201876
0.936884
0.209277
0.324705
0.311334
</code></pre>
<p>I tried to generate completely different numbers no matter how many I computed before, but the first is alway close to the same.</p>

<p>I wish to create a custom calculator where the user defines two parameters and a function using a GUI and when they click on calculate it executes their user defined function passing the two parameters.</p>
<pre class="lang-py prettyprint-override"><code>argument1 = IntSlider( … )
argument2 = IntSlider( … )
userDefinedFunction = TextArea( … )
calculateButton = Button ( … )
calculateButton.on_click(userDefinedFunction)
</code></pre>
<p>So that let’s say somebody defines :</p>
<ol>
<li><code>argument1 = 3</code></li>
<li><code>argument2 = 4</code></li>
<li><code>userDefinedFunction = def udf(arg1,arg2): return arg1**2 + arg2**2</code></li>
</ol>
<p>Would return 25 as <code>3*3 + 4*4 = 25</code>.</p>

<p>so i'm taking a python class right now and am struggling with dictionaries at the moment. my assignment is simple, i have to create a fucntion "letter_positions" which will return a dictionary of all positions of a letter in a string.</p>
<p>for example</p>
<pre><code>positions = letter_positions("fifteen e's, seven f's, four g's, six h's, eight i's, four n's, five o's, six r's, eighteen s's, eight t's, four u's, three v's, two w's, three x's")
positions['e']
</code></pre>
<p>should return</p>
<pre><code>{4, 5, 8, 14, 16, 43, 67, 83, 88, 89, 97, 121, 122, 141, 142}
</code></pre>
<p>so i'm pretty much done with the assignment but i'm running into the issue that i have all values (positions) assigned to the keys (letters) as a list.</p>
<p>here's my code:</p>
<pre><code>def letter_positions(n):
answer = {}
n = n.lower()
x = 0
for letter in n:
if letter.isalpha():
if letter not in answer:
answer[letter] = []
answer[letter].append(x)
x += 1
return answer
</code></pre>
<p>so instead of getting a dictionary of positions i'm getting a list of positions.</p>
<pre><code>positions = letter_positions("fifteen e's, seven f's, four g's, six h's, eight i's, four n's, five o's, six r's, eighteen s's, eight t's, four u's, three v's, two w's, three x's")
positions['e']
</code></pre>
<p>returns</p>
<pre><code>
[4, 5, 8, 14, 16, 43, 67, 83, 88, 89, 97, 121, 122, 141, 142]
</code></pre>
<p>is there any way for me to simply change the list into a dictionary or am i approaching this in a completely wrong way?</p>

<p>why this is not working?? anything else i need to doo??? (note: i don't want to call any <code>boot</code> method from <code>model</code>). in models its working fine with <code>booted</code> method</p>
<pre class="lang-php prettyprint-override"><code>// route
Route::get('/tests', function () {

'name' => Str::random(6)
]);

<p>I have a dataset like below:</p>

</code></pre>
<p>These are separate lines. Now, I want to group the data in a <code>set of 3 rows</code> and find the intersecting character in those lines. For example, <code>r</code> is the common character in the first group and <code>Z</code> is the typical character in the second group. So, below is my code:</p>
<pre><code>lines = []
for i in range(len(data.splitlines())):
lines.append(data[i])
for j in lines:
new_line = [k for k in j[i] if k in j[i + 1]]
print(new_line)
</code></pre>
<p>It gives me a string index out-of-range error.</p>
<pre><code>new_line = [k for k in j[i] if k in j[i + 1]]
IndexError: string index out of range

<p>I have a scenario where I have a git branch (b), based off of develop.</p>
<p>I then made changes to branch (b) and pushed to remote (b)</p>
<p>Some other developer made a PR and had their code merged into develop.</p>
<p>I then pull the changes from remote/develop and rebased my local branch (b) onto develop</p>
<p>I then make more changes to my local branch (b)</p>
<p>When I commit and push my changes, I get a rejected error:
[! [rejected] feature/b-> feature/b (non-fast-forward)
error: failed to push some refs to 'gitlab'
hint: Updates were rejected because the tip of your current branch is behind]</p>
<p>What I normally tend to do is to do a --force push</p>
<p>But I'm wondering if this is the right approach?</p>

<p>I want to build a program that takes the amount of rainfall each day for 7 days and then output the total and average rainfall for those days.</p>
<p>Initially, I've created a while loop to take the input:</p>
<pre class="lang-py prettyprint-override"><code>rainfall = 0
rain = []
counter = 1
while counter < 8:
rain.append(rainfall)
rainfall = float(input("Enter the rainfall of day {0}: ".format(counter)))
counter += 1
print(rain)
</code></pre>
<p>But the output that is generated is not what I expected:</p>
<pre class="lang-py prettyprint-override"><code>[0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0]
</code></pre>
<p>It will enter a 0 as first value and then omit the last input (here the input is 1 to 7 as an example)</p>

<p>I have simple istream_view and then I am trying to use ranges::copy on result.</p>
<pre><code>auto t = ranges::istream_view<int>(is);
ranges::copy(t, std::back_inserter(v));
</code></pre>
<p><a href="https://godbolt.org/z/1ro9x3nh1" rel="nofollow noreferrer">Live example on godbolt</a></p>
<p>GCC does everything ok, clang fails with error:</p>
<pre><code>error: no matching function for call to object of type 'const std::ranges::__copy_fn'
ranges::copy(t, std::back_inserter(v));
</code></pre>
<p>Probably it is because istream_view is moveonly view.</p>
<p>How to argue in this case who is right?</p>
<p>Standard C++20 [range.istream.overview] have similar example:</p>
<pre><code>auto ints = istringstream{"0 1 2 3 4"};
ranges::copy(ranges::istream_view<int>(ints), ostream_iterator<int>{cout, "-"});
</code></pre>
<p>Which also fails in clang (and this is definitely a bug but I am not sure that reason is the same for both compile-time errors).</p>

<p>I am working on a homework problem which is similar to this post:-
<a href="https://stackoverflow.com/questions/5859519/quickest-algorithm-to-find-at-most-n-2-1-liars-in-n-people">Quickest algorithm to find at most (n/2)-1 liars in n people</a></p>
<p>The problem is given below:-
This problem is couched in terms of liars and truth tellers, but it has real applications in identifying which components of a complex system are good (functioning correctly) and which are faulty. Assume we have a community of n people and we know an integer number t < n/2, which has the property that most t of the n people are liars. This does not say that there actually are t liars, but only that there are at most t liars.</p>
<p>The difference in my case is that the truth-tellers are always truthful and correct and a liar always speaks a lie.</p>
<p>We will identify the liars in the community by successively picking pairs of people, (X, Y) say, and asking X: Is Y a liar?. The response is either “yes” or “no";</p>
<p>What is the optimum algorithm(minimum number of steps) to find all the liars?</p>

<p>I'm trying to get common characters from two separate vectors.</p>
<p>Example:</p>
<pre><code>x <- c("abcde")
y <- c("efghi")
df <- data.frame(x, y)
</code></pre>
<p>Desired output</p>
<pre><code> x y z
abcde efghi e
lmnop uvmxw m
</code></pre>
<p>I've tried something like this, but it is a bad result:</p>
<pre><code>df |> mutate(m = unique(x, y))
</code></pre>
<p>If there are multiple matches, returning a list would work great.</p>

<p><em><a href="https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=d69eee7953a6392d12c81a77a21cf15a" rel="nofollow noreferrer">Playground</a></em></p>
<p>I have the following type definition:</p>
<pre class="lang-rust prettyprint-override"><code>pub struct UTF8Chars {
bytes: Peekable<Box<dyn Iterator<Item = u8>>>,
}
</code></pre>
<p>Now I'm wondering how to actually create an instance of this struct.</p>
<p>I've tried <em>(and yes, this is inside a trait implementation if that is an important detail)</em>:</p>
<pre class="lang-rust prettyprint-override"><code>impl<'a> ToUTF8Chars for &'a str {
fn utf8_chars(self) -> UTF8Chars {
let bytes = Box::new(self.bytes()).peekable();
UTF8Chars { bytes }
}
}
</code></pre>
<p>That gives me the error:</p>
<pre><code>expected struct `Peekable<Box<(dyn Iterator<Item = u8> + 'static)>>`
found struct `Peekable<Box<std::str::Bytes<'_>>>`
</code></pre>
<p>Forgive me if I try weird things, but I haven't gotten the hang of this intricate trait stuff yet. For all I know, rust-analyzer was telling me that <code>Bytes</code> in fact an <code>impl Iterator<Item = u8></code>. So, next thing I tried was casting it first:</p>
<pre class="lang-rust prettyprint-override"><code>let bytes = Box::new(self.bytes()) as Box<dyn Iterator<Item = u8>>;
UTF8Chars { bytes: bytes.peekable() }
</code></pre>
<p>That sort of works, but now the lifetime checker is complaining:</p>
<pre><code>impl<'a> ToUTF8Chars for &'a str {
-- lifetime `'a` defined here
fn utf8_chars(self) -> UTF8Chars {
let bytes = Box::new(self.bytes()) as Box<dyn Iterator<Item = u8>>;
^^^^^^^^^^^^^^^^^^^^^^ cast requires that `'a` must outlive `'static`
</code></pre>
<p>I'm not exactly sure what is going out of scope here... as far as I know, I own the result from <code>.bytes()</code> (I also tried with an additional <code>.clone()</code> in case that assumption was incorrect), I own the <code>Box</code>, the <code>Box</code> is passed to <code>Peekable</code>, and finally <code>Peekable</code> is passed to <code>UTF8Chars</code>. What <em>exactly</em> is the issue here? Why do I somehow need to outlive <code>static</code>...?</p>
<p>I found this issue that seems similar, sadly no answer: <a href="https://stackoverflow.com/questions/59551656/peekable-of-an-iterator-in-struct">Peekable of an Iterator in struct</a>.</p>
<h3>Why I want to do this?</h3>
<p>Well, mainly because I don't really care, or am unable to care what exactly the underlying data is. I just need to know that I can <code>.peek()</code>, and <code>.next()</code>, etc. This is, because sometimes I want to assign different things to <code>self.bytes</code>. For example, <code>Chain<...></code>, or <code>Copied<...></code> instead of a simple <code>vec::IntoIter<...></code>.</p>
<p>If there is an alternative approach to this, I'm happy to hear about it.</p>

<p>And I create dict 'a' with this block of code:</p>
<pre><code>a = {}
b=[]
for _, contents in tr.items():
b.clear()
for ind, val in enumerate(contents):
if np.isnan(val):
b.append(ind)
continue
else:
pass
print(_)
print(b)
a[_] = b
print(a)
</code></pre>
<p>Which gives me this output:</p>
<pre><code>7128
[3, 4, 5, 7, 8, 9]
{7128: [3, 4, 5, 7, 8, 9]}
8719
[7, 8, 9]
{7128: [7, 8, 9], 8719: [7, 8, 9]}
14051
[3, 4, 5, 6, 7, 8, 9]
{7128: [3, 4, 5, 6, 7, 8, 9], 8719: [3, 4, 5, 6, 7, 8, 9], 14051: [3, 4, 5, 6, 7, 8, 9]}
14636
[3, 4, 5, 6, 7, 8, 9]
{7128: [3, 4, 5, 6, 7, 8, 9], 8719: [3, 4, 5, 6, 7, 8, 9], 14051: [3, 4, 5, 6, 7, 8, 9],
14636: [3, 4, 5, 6, 7, 8, 9]}
</code></pre>
<p>What I expect dict 'a' to look like is this:</p>
<pre><code>{7128: [3, 4, 5, 7, 8, 9]
8719: [7, 8, 9]
14051: [3, 4, 5, 6, 7, 8, 9]
14636: [3, 4, 5, 6, 7, 8, 9]}
</code></pre>
<p>What I am doing wrong? Why is <code>a[_] = b</code> overwriting all the previous keys when <code>print(_)</code> is verifying that _ is always the next column label?</p>

<p>I want to scrape the tweets of a specific account on Twitter via SB but it is not working for me</p>
<p>this is my code :</p>
<pre><code> import facebook as fb
from bs4 import BeautifulSoup as bs
import requests
myUrl = requests.get('https://twitter.com/search?q=(from%3AAlMosahf)&src=typed_query&f=live')
source = myUrl.content
soup = bs(source, 'html.parser')
twi = soup.find_all('div', {'data-testid':'tweetText'})
myTW = twi[1].text
print(myTW)
</code></pre>
<p>The result is "list index out of range" .. because "twi" is empty</p>

<p>I installed the latest nodejs 19.2.0 on my windows 11 OS rather than the recommended for most users 18.12.1
<code>npx create-react-app my-first-app</code> works just fine, it creates all the files and folders without any errors, shows happy hacking message as well, recommends to use <code>npm start</code> command. I go inside <code>my-first-app</code> folder, go <code>npm start</code> and I get a module not found error...like this picture
<a href="https://i.stack.imgur.com/Y1tci.png" rel="nofollow noreferrer">Error Message Screenshot</a></p>
<p>In youtube tutorials, there is no any error in their pc. <code>npm start</code> runs just as easily as <code>npx create-react-app <anyappname></code>.</p>

<p>I have 4 inputs in my panel; when user clicks <code>cancel</code> I need to revert to the original values before they're modified. Is there a Vuetify or Vue.js way to achieve this? or do I have to manage it using JS by storing all values in a tmp variable?</p>

<p>I'm not very good in English or in R but hopefully I can manage to explain the problem</p>
<p>I have a dataset where there is one column with years, from 1952 to 2007. I want to recode and reorganize it so that the first year is number 0, the next year nr. 1 and so on...</p>
<p>Can anyone help me?</p>
<p>I have tried recode(), arrange (),</p>

<p>Here is an example of some of the information in the text file:</p>
<pre><code>Ticker : Ticker representing the company | Company: Name | Title: Position of trader | Trade Type: Buy or sell | Value: Monetary value
Ticker : AKUS | Company: Akouos, Inc. | Title: 10% | Trade Type: P - Purchase | Value: +$374,908,350
Ticker : HHC | Company: Howard Hughes Corp | Title: Dir, 10% | Trade Type: P - Purchase | Value: +$109,214,243
</code></pre>
<p>Where each time it says ticker, it's a new line. Is there a way to pull out specific information and set it to a dictionary? For example, would I be able to get a dictionary filled with all the tickers, all the positions and all of the monetary values?</p>

<p>I have a socket server which creates unix socket and then reads data from this unix socket. Then I have another long-process application and I want to redirect stdout of this process to my unix socket. I tried this command to test</p>
<pre><code>ping 127.0.0.1 > /tmp/unixsockettest.sock
</code></pre>
<p>But I get <code>-bash: /tmp/unixsockettest.sock: No such device or address</code>. Is it possible to redirect application output to unix socket?</p>

<p>I am a bit confused about the use of <code>srcset</code> attribute in the HTML <code>img</code> tag. I read several tutorials on the Web but I think stuff doesn't work as these tutorial report. First of all, let's start with an easy example:</p>
<pre><code><img src="assets/img/software-developer.jpeg" alt="Some Stuff" srcset="assets/img/software-developer-300.jpeg 300w, assets/img/software-developer.jpeg 450w">
</code></pre>
<p>I have two images:</p>
<ul>
<li><code>assets/img/software-developer.jpeg</code> 450x450 pixels</li>
<li><code>assets/img/software-developer-300.jpeg</code> 300x300 pixels</li>
</ul>
<p>Now I use Chrome Developer Tools for tests, but whatever screen size I select I always see that <code>assets/img/software-developer.jpeg</code> is downloaded. I can see it in the Developer Tools Properties tab looking at the property <code>currentSrc</code>.</p>
<p><strong>Can anyone help me to understand why?</strong> I want that:</p>
<ul>
<li>for screen with size >= 450px then <code>assets/img/software-developer.jpeg</code> is downloaded</li>
<li>for screen with size < 450px then <code>assets/img/software-developer-300.jpeg</code> is downloaded</li>
</ul>
<p>Another thing that it's not clear to me is: <strong>what happens with screen size < 300px?</strong></p>
<p>If the image with lowest width is <code>assets/img/software-developer-300.jpeg</code> that is 300x300 pixels, how I can modify the code to let it resize (become smaller in this case) to fit the viewport?</p>
<p>For example, Developer Tools by defaul has Galaxy Fold device that has a width of 280 pixel. In this case, both the images don't fit the screen size: <strong>how I can define my srcset to let it resize in this situation?</strong></p>
<p>Web is full of information about this stuff, at a first read things are a bit confusing so I decided to start with small tests. The first tests I decided to work on is with <code>srcset</code> and check if the image downloaded is the one expected. It seems the tag doesn't work as expected. I know that I am missing something, hoping someone here can help to clarify.</p>

<p>My project is using Spring and I wanted to test with Mockito but I have a NullPointerException that I can't solve...
Isn't MockBean supposed to inject in my TeacherService ?
I have tried to put @Autowired in front of MockMvc but it's worse...</p>
<p>I want to test my Controller by adding a new Teacher :</p>
<p>This is my test :</p>
<pre><code>@ExtendWith(MockitoExtension.class)
@ExtendWith(SpringExtension.class)
@AutoConfigureMockMvc
public class TeacherControllerMockTest {
private MockMvc mvc;
@InjectMocks
private TeacherForm teacherForm;
@MockBean
private TeacherService teacherService;
@Captor
ArgumentCaptor<Teacher> teacherCaptor;
@Test
void addTeacherPostNonExistingTeacher() throws Exception {
when(teacherService.findById(teacherForm.getId())).thenReturn(null);
//il y aura un teacherService.saveTeacher(t) : mais par defaut ça ne le fera pas
this.mvc.perform(post("/addTeacher")
.param("firstName", "Anne-Marie")
.param("lastName", "Kermarrec")
)
.andExpect(status().is3xxRedirection())
.andReturn();
//teacherController.addTeacher(teacherForm);
verify(teacherService, atLeastOnce()).saveTeacher(teacherCaptor.capture());
Teacher capturedTeacher = teacherCaptor.getValue();
assertEquals("Kermarrec", capturedTeacher.getLastName());
}
</code></pre>
<p>This is my Controller :</p>
<pre><code>@PostMapping(value = { "/addTeacher"})
public String addTeacher(@ModelAttribute("TeacherForm") TeacherForm teacherForm) {
Teacher t;
if(teacherService.findById(teacherForm.getId()).isPresent()){
// teacher already existing : update
t = teacherService.findById(teacherForm.getId()).get();
t.setFirstName(teacherForm.getFirstName());
t.setLastName(teacherForm.getLastName());
} else {
// teacher not existing : create
t=new Teacher(teacherForm.getFirstName(), teacherForm.getLastName(), terManagerService.getTERManager());
}
teacherService.saveTeacher(t);
return "redirect:/listTeachers";
}
</code></pre>
<p>And the error :</p>
<pre><code>java.lang.NullPointerException: Cannot invoke "org.springframework.test.web.servlet.MockMvc.perform(org.springframework.test.web.servlet.RequestBuilder)" because "this.mvc" is null

//I have add this line because I got thie.teacherService is null
this.teacherService = new TeacherService();

<p>I got a problem with this.teacherRepository is null (teacherRepository is an interface), it is used when I'm calling teacherService.findById</p>

<p>I am trying to make an tracker app in witch I an user can create a group and when clicked on "show on map" it would show all of members position. I have made group info page in witch there is a Add members button. When clicked it takes the user to a new page. In that new page he searches for an different user witch he wants to add. When clicked on search icon under the TextFormField there is an ListTile. When tapped on that ListTile searched user should be added to that group and the searcher should be redirected back to group info page.</p>
<p>I am stuck at the part in which I try to add users to an existing group but I get an error:</p>

<p>So I'm writing a simple C program that essentially creates a 2D array and allows the user to input values into the 2D array. Then other functions find the smallest and largest value within that array, as well as their position in the array. When I print the matrix in the function, it prints correctly as it should. However, whenever I print it in main as a test or try to access it in my other functions, my array goes from 1, 2, 3, 4, etc. to 1, 1, 1, 1. I used the same function in a previous code I wrote, and it worked just fine, so I'm kind of stumped. Also, I'm not allowed to modify main, I just put a simple loop to print the array there as a test. This is my first time posting here, so I apologize if my formatting is wrong. Any help would be greatly appreciated.</p>
<p>Here is my code:</p>
<pre><code>#include <stdio.h>
#define ROWS 4
#define COLS 3
void generateMtx(int mtx[ROWS][COLS])
{
for (int i = 0; i < ROWS; i++)
{
for (int j = 0; j < COLS; j++)
{
printf("Enter row %d, column %d: ", i, j);
scanf("%d", &mtx[i][j]);
}
}
//Test print in function
for (int i = 0; i < ROWS; i++)
{
for (int j = 0; j < COLS; j++)
{
printf("%d ", mtx[i][j]);
}
printf("\n");
}
}
int matrixSmallest(int arr[ROWS][COLS])
{
int smallest = arr[0][0];
for (int i = 0; i < ROWS; i++)
{
for (int j = 0; j < COLS; j++)
{
if (smallest > arr[i][j])
{
smallest = arr[i][j];
}
}
}
return smallest;
}
int matrixLargest(int arr[ROWS][COLS])
{
int largest = arr[0][0];
for (int i = 0; i < ROWS; i++)
{
for (int j = 0; j < COLS; j++)
{
if (largest < arr[i][j])
{
largest = arr[i][j];
}
}
}
return largest;
}
int elementPosition(int arr[ROWS][COLS], int num, int pos[2])
{
for (int i = 0; i < ROWS; i++)
{
for (int j = 0; j < COLS; j++)
{
if (arr[i][j] = num)
{
pos[0] = i;
pos[1] = j;
}
}
}
return pos[2];
}
int main()
{
int mtx[ROWS][COLS];
generateMtx(mtx);
int smallest = matrixSmallest(mtx);
int smallPosition[2] = {-1, -1};
elementPosition(mtx, smallest, smallPosition);
int largest = matrixLargest(mtx);
int largePosition[2] = {-1, -1};
elementPosition(mtx, largest, largePosition);
printf("Largest element: %d\n", largest);
printf(" found at row %d, column %d\n", largePosition[0], largePosition[1]);
printf("Smallest element: %d\n", smallest);
printf(" found at row %d, column %d\n", smallPosition[0], smallPosition[1]);
//Test print in main
//Can't modify main
for (int i = 0; i < ROWS; i++)
{
for (int j = 0; j < COLS; j++)
{
printf("%d ", mtx[i][j]);
}
printf("\n");
}
return 0;
}

<p>I've got XML files that contain HTML snippets. I'm trying to write a Python script that opens such an XML file, searches for the elements containing the HTML, renames the classes, and then writes back the new XML file to file.
Here's an XML example:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<question_categories>
<question_category id="18883">
<name>templates</name>
<questions>
<question id="1419226">
<parent>0</parent>
<name>_template_master</name>
<questiontext>
&lt;div class=&quot;wrapper&quot;&gt;
&lt;div class=&quot;wrapper element&quot;&gt;
&lt;span&gt;Exercise 1&lt;/span&gt;
&lt;/div&gt;
&lt;/div&gt;
</questiontext>
</question>
<question id="1419238">
<parent>0</parent>
<name>_template_singleDropDown</name>
<questiontext>
&lt;div class=&quot;wrapper&quot;&gt;
&lt;div class=&quot;element wrapper&quot;&gt;
&lt;span&gt;Exercise 2&lt;/span&gt;
&lt;/div&gt;
&lt;/div&gt;
</questiontext>
</question>
</questions>
</question_category>
</question_categories>
</code></pre>
<p>The element containing the HTML is <code><questiontext></code>, the HTML class to be renamed is <code>wrapper</code>, and the new class name should be <code>prefixed-wrapper</code>.</p>
<p>I succeeded to loop through the XML, extracting the HTML and also to rename the class, but I don't know how to put everything together, so at the end I get an XML file with the renamed class names.
This is my code so far:</p>
<pre><code>from bs4 import BeautifulSoup
with open('dummy_short.xml', 'r') as f:
file = f.read()
soup_xml = BeautifulSoup(file, 'xml')
for questiontext in soup_xml.find_all('questiontext'):
for singleclass in BeautifulSoup(questiontext.text, 'html.parser').find_all(class_='wrapper'):
pos = singleclass.attrs['class'].index('wrapper')
singleclass.attrs['class'][pos] = 'prefixed-wrapper'
print(soup_xml)
</code></pre>
<p>Unfortunately, when printing soup_xml at the end, the contents are unchanged, i.e. the class names aren't renamed.</p>
<p><strong>EDIT:</strong> Since one and the same class name can occur in very different and complex contexts (for example along with other classes, i.e. <code>class="xxx yyy wrapper zzz"</code>), a static match isn't working. And instead of using complicated and non-comprehensible regexes, I have to use a parser like beautifulsoup (because they are made exactly for this purpose!).</p>

<p>I have a form in Excel and I need to return data from a table in access. When executing an instruction like the image it returns the error "Data Type Mismatch in Criterion Expression". I already reviewed the data types in the table and still could not resolve. What could be happening?</p>
<pre><code> Sub pesquisar()
Set rs = New ADODB.Recordset
conectdb
rs.Open "SELECT * FROM TbApolice WHERE Contrato='" & UserForm.txt_certificado.Value & "'", db, adOpenKeyset, adLockReadOnly
If UserForm.txt_certificado.Value <> "" Then
UserForm.txt_nome = rs!Nome
UserForm.txt_cpf = rs!CPF
UserForm.txt_iniciovigencia = rs!Inicio_vigencia
UserForm.txt_fimvigencia = rs!Fim_de_vigencia
UserForm.txt_premio = rs!Premio
Else
MsgBox "Segurado não localizado", vbInformation, "LOCALIZAR"
End If
If Not rs Is Nothing Then
rs.Close
Set rs = Nothing
End If
fechadb
End Sub
</code></pre>
<p>I've already made some attempts to point break and debug the code, in addition to validating all fields and data types, but I didn't get any results.</p>

<p>I'm trying to create custom function in WordPress with ACF, and use it as a shortcode.</p>
<p>What I want to do is quite simple:</p>
<ul>
<li>Get a field from ACF</li>
<li>Check if the text is "not found" or something else</li>
<li>If it's something else, I'll show an H2 and a sentence with field content.</li>
<li>If its "not found" I don't want to show anything</li>
</ul>
<p>I tried various code, here's my last one:</p>
<pre><code>// write a shortcode that creates a text if the field is not "not found"
function show_alliance() {
$alliance = get_field('field_6383d4b46deed');
if ($alliance !='not found'): {
return '<h2>TITLE</h2><p>This is... '. $alliance .' </p>';
}
else: {
return '';}
}
add_shortcode('alliance', 'show_alliance')
</code></pre>
<p>By WordPress always comes up with errors when I save my snippet. I can't find a way to make it work.</p>
<p>(I use Code Snippets in WordPress)</p>
<p>Any ideas?
(I'm sure it's very simple...)</p>
<p>--</p>
<p>Tried different syntax, but WordPress never validates the code snippet.</p>
<p>Last one is:</p>
<p>`L’extrait de code que vous essayez d’enregistrer a produit une erreur fatale à la ligne 11 :</p>
<p>syntax error, unexpected '}'`</p>
<p>When I delete the } to put it a the end it tells me that I should not have it there...</p>

<p>I'm working a project for school in T-SQL.</p>
<p>I have an Advisors table that is fully set up. I'm trying to update the Student table so that each StudentID is associated with an AdvisorID (referencing the Advisors table). The Student table is fully set up, minus the AdvisorID column. Both tables have Name_Full, Name_First, and Name_Last for every Advisor and Student in the respective tables.</p>
<p>I'm trying to find all students that have a Name_Last starting with 'R'. I know for a fact that there is at least one student that qualifies since there is a student with a Name_Last = 'Ramos'.</p>
<p>I tried searching for every student with a Name_Last starting with the letter 'R' using the following code.</p>
<pre><code>SELECT Name_Last
FROM Student
WHERE Name_Last IN ('R%')
</code></pre>
<p>This query returns nothing. I've tried using '=' and 'LIKE' instead of 'IN' and those did not work either. I've tried using 'CONTAINS' which also didn't work. I tried:</p>
<pre><code>WHERE CHARINDEX('R', Name_Last) = 1
</code></pre>
<p>This did not work either.
Once I get this working, I'd like to be able to copy it into a WHERE clause using BETWEEN, as I want to assign an AdvisorID to students within certain ranges.</p>

<p>I am working on Reactjs and using nextjs, Right now i am trying to get value
of "textarea" and "dropdown/select", but i am getting empty result,How can i do this ?
I tried with following code</p>
<pre><code> const msgChange = (e) => {
const value = e.target.value;
setState({
...state,
[e.target.msg]: value
});
};
const countryChange = (e) => {
const value = e.target.value;
setState({
...state,
[e.target.country]: value
});
};
const handleSubmit = (e) => {
var msg = state.msg;
alert('msg is '+msg);
}
<form className='row' onSubmit={handleSubmit}>
<select className="form-select" aria-label="Default select example" onChange={countryChange} name="country">
<option selected>Country</option>
<option value="abc">abc</option>
<option value="xyz">xyz</option>
</select>
<textarea onChange={msgChange} name="msgs"></textarea>

<p>I want to make multiple calls for which I have to wait for the answer, and afterwards I want to group all responses in an array. I've not succeeded to do this.</p>
<p>The <code>res</code> constant in code below still retains the array of promises, not their results. I have no idea what else to try. No other stackoverflow answers have been helpful.</p>
<p>What I've tried:</p>
<pre><code>const getProjectData = async (projectID) => await callAPI(`/projects/${projectID}`);
const solve = async () => {
const projects = [];
currentUserProjectIDs.forEach((project) => {
projects.push(getProjectData(project));
});
console.log("projects", projects);
const res = await Promise.all(projects);
console.log("solve res", res);
return res;
};
const res = await solve();
console.log("res", res);
</code></pre>
<p>Below is the result of the last console log:</p>
<pre><code>
res [
Response {
size: 0,
timeout: 0,
[Symbol(Body internals)]: { body: [PassThrough], disturbed: false, error: null },
[Symbol(Response internals)]: {
url: 'http://localhost:4000/projects/1',
status: 200,
statusText: 'OK',
headers: [Headers],
counter: 0
}
},
Response {
size: 0,
timeout: 0,
[Symbol(Body internals)]: { body: [PassThrough], disturbed: false, error: null },
[Symbol(Response internals)]: {
url: 'http://localhost:4000/projects/4',
status: 200,
statusText: 'OK',
headers: [Headers],
counter: 0
}
}
]
</code></pre>
<p><code>callAPI</code> function:</p>
<pre><code>export const callAPI = async (path, body, method = "GET") => {
const config = {
method: method,
headers: {
"Content-Type": "application/json",
},
};
if (body) {
config.body = JSON.stringify(body);
}
const URL = `${process.env.HOST}${path}`;
return await fetch(URL, config);
};
</code></pre>
<p>EDIT:
I have tried another way, but still unsuccessful. In the code below, the console.log inside the second <code>.then()</code> logs the correct data, but the returned <code>prj</code> is still an empty array...</p>
<pre><code>const solve = async () => {
const projects = [];
currentUserProjectIDs.map((p) => {
callAPI(`/projects/${p}`)
.then((r) => {
return r.json();
})
.then((a) => {
console.log("a", a);
projects.push(a);
return a;
});
});
return projects;
};
const prj = await solve();
console.log("prj", prj);
</code></pre>

<p>``
hi everyone, I want to take color as input and then change the color of text according to it but it's not working can anybody help me.</p>
<pre><code>import React, {useState} from 'react'
export default function Textform(props) {
//this is function
const newColor =()=>{
const x = document.getElementById("mybox")
let newc =color;
if(x.style.color==="black"){
x.style.color = setcolor(newc)
}
else{
x.style.color = "black"
}
}
const changeColor =(event)=>{
setcolor(event.target.value);
}
const onChange =(event)=>{
setText(event.target.value);
}
const [text, setText] = useState("");
const [color, setcolor] = useState("")
return (
<>
//text area input
<div className="mb-3">
<textarea className="form-control" value={text} onChange={onChange} placeholder="Enter text " name="" id="mybox" rows="8"></textarea>
</div>
//our color choice input
<div className="mb-3">
<textarea className="form-control" value={color} onChange={changeColor} placeholder="Enter your color choice" name="" id="mybox" rows="3"></textarea>
</div>
//this is my button
<button className="btn btn-primary mx-1" onClick={newColor}> Change Color</button>
</>
)
}
</code></pre>
<p>I tried to create a text Area which take text as input and another text Area which take color as input and then created a button. when we press the button, it will change the color of text as per our choice.
but I am going wrong in implementing this logic.</p>

<p>Innocent React question here.</p>
<p>I have a <code>useEffect</code> method that closes a modal on the <code>escape</code> keypress, that is duplicated a few times in my code, that looks like this:</p>
<pre><code>const [shouldShowModal, setShouldShowModal] = useProfileModal();
useEffect(() => {
const closeModalOnEscape = (e: KeyboardEvent | any): void => {
if (e.key === "Escape") setShouldShowModal(false);
};
document.addEventListener("keydown", closeModalOnEscape);
return () => {
document.removeEventListener("keydown", closeModalOnEscape);
};
}, [setShouldShowModal]);
</code></pre>
<p>Is there a way I can define the <code>useEffect</code> piece to use across multiple components?</p>

<p>Take this vector:</p>
<pre><code>std::vector<int> v = {1, 2, 3, 4, 5};
</code></pre>
<p>Let's say I want to remove some elements of a vector at some arbitrary indices: 0, 1, and 3. It's tedious to have to write something like this:</p>
<pre><code>v.erase(v.begin());
v.erase(v.begin());
v.erase(v.begin() + 1);
</code></pre>
<p>Is there any standard function that takes in an arbitrary number of indices to erase from a vector? Something like this: <code>v.erase(0, 1, 3);</code></p>

<p>What's happening:<br>
<a href="https://i.stack.imgur.com/mdtyX.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mdtyX.gif" alt="enter image description here" /></a></p>
<p>Everytime I add value to height.. the 'top-most' area is causing to mess-up the y.position of the gameObject.</p>
<p>The <strong>GOAL</strong> is: <br>
<a href="https://i.stack.imgur.com/X8Fqv.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/X8Fqv.gif" alt="enter image description here" /></a></p>
<br>
How to achieve this kind of approach/behavior via script that makes the 'top-most' area stay?
<p><strong>Thank you in advance. Best regards.</strong></p>

<p>Django admin site used to have a form to change the password for a user that wasn't the logged in user. You would look at the user's update page, and by the password field, there was a change password link. You would click it, and it would take you to a different page for changing the password. I used to take advantage of that page to allow changing of a user's password, without having to open the admin. In Django 4, it seems to now be missing. In fact, I can't figure out how one would change a user's password other than their own, without writing my own view.</p>
<p>I have 2 questions:</p>
<ol>
<li>Is there a way in the admin site now to change a different user's password?</li>
<li>If this view is gone, what is now the best way for a superuser to have a view that can change passwords for a user?</li>
</ol>
<p><strong>Edit:</strong>
This is what I see. There is no link to change the password where there used to be.

<p>I want a gray overlay above all children except for the <code>selected</code> one. Given the following structure:</p>
<pre><code><div class="parent">
<!-- I have this subparent which is absolute. I cannot remove it... -->
<div class="subParent1">
<div class="subParent2">
<!-- This child I want to be above the OVERLAY, aka not greyed out -->
<div class="child selected">child</div>
<div class="child">child</div>
<div class="child">child</div>
</div>
</div>
<!-- This component is underneat subParent in the tree structure -->
<div class="grayOverlay"></div>
</div>
</code></pre>
<p><a href="https://jsfiddle.net/xyfb3e2h/2/" rel="nofollow noreferrer">Here's an exact fiddle</a>. Maybe, I could use a pseudo-element instead?</p>
<p>PS: I updated the children to be a bit more nested to align with my actual code.</p>

<p>I have table Buyer</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>BuyId</th>
<th>QuantityOrdered</th>
<th>dateordered</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>10</td>
<td>2021-11-04</td>
</tr>
<tr>
<td>1</td>
<td>20</td>
<td>2022-01-22</td>

<tr>
<td>2</td>
<td>50</td>

</table>
</div>
<p>I need to select all BuyId's who consecutively had higher QuantityOrder in each new record</p>
<ul>
<li>buyid=1 had first order with quantity=10, second order with quantity=20</li>
<li>buyid=2 had first order with quantity=50, second order with quantity=60</li>
</ul>
<p>So BuyId=1 and 2 would enter the results, while 3 and 4 would be filtered out because they had only one order or they did not have orders with consecutively higher quantities ordered</p>
<p>I tried with this, and I'm aware that this query gives me only buyid's who have more than one order, but I am missing the rule where I have to filter results out by quantity increased with each new order</p>
<pre><code>select buyid, count(*) as ordered
from buyer
group by buyid
having count(*) >1
</code></pre>
<p>How would I write out that rule in a query, to select only BuyId's who had multiple orders, and in each new order they ordered higher quantities than in previous orders?</p>

<p>I looked through so many tutorials and it's still not working for me. I have a database that looks like this:
<a href="https://i.stack.imgur.com/QdXeB.png" rel="nofollow noreferrer">databaseImage</a>
Note that the actual row does not match up with the id. I would like to delete from the actual row rather than using the id.</p>
<p>I have the following function:</p>
<pre><code>`fun deleteDBData(TABLE_NAME:String, rowID : Int) {
val db = this.writableDatabase
db.delete(TABLE_NAME, "$ID_COL=$rowID", null)
}`
</code></pre>
<p>This however, deletes using the number in the id column rather than the actual row. So with this function, if I tell it to delete rowID = 4, it will delete row 1 rather than row 4. How do I get sqlite to delete row 4?</p>

<p>I have to write a program that has a <strong>constructor without parameters</strong>. I created another short program as an example to show what I do not understand.
So I have a class with the main-method:</p>
<pre><code>public class Dog {
public static void main(String[] args) {
CharacteristicsOfTheDog Dog1 = new CharacteristicsOfTheDog(20, 40);
System.out.println(Dog1.toString());
}
}
</code></pre>
<p>Now implemented another class:</p>
<pre><code>public class CharacteristicsOfTheDog {
int size = 0;
int kilogram = 0;
public CharacteristicsOfTheDog(/*int size, int kilogram*/) {
// this.size = size;
// this.kilogram = kilogram;
}
public double getSize() {
return size;
}
public double getKilogram() {
return kilogram;
}
public String toString() {
return "The Dog is " + getSize() + " cm and " + getKilogram() + " kg";
}
}
</code></pre>
<p>In the class "CharacteristicsOfTheDog" in "public CharacteristicsOfTheDog()" I removed the parameters by commenting them out. So the Problem is: if I remove the parameters the program does not work:/ but my task is to do this without the parameters (as far as I understood). Can someone help me please?</p>

tweets_df.drop(tweet_index , inplace=True)
print(tweets_df)

<p>Edit: Also, fuzzy, case-insensitive matching with stemming would be preferred when searching the 'text' for countries and regions.</p>
<p>Ex) If the text contained 'Ukrainian', 'british', 'engliSH', etc... then it would not be deleted</p>

<p>I got tasked with writing a Python script that would output the longest chain of consecutive words of the same length from a sentence. For example, if the input is "To be or not to be", the output should be "To, be, or".</p>
<pre><code>text = input("Enter text: ")
words = text.replace(",", " ").replace(".", " ").split()
x = 0
same = []
same.append(words[x])
for i in words:
if len(words[x]) == len(words[x+1]):
same.append(words[x+1])
x += 1
elif len(words[x]) != len(words[x+1]):
same = []
x += 1
else:
print("No consecutive words of the same length")
print(words)
print("Longest chain of words with similar length: ", same)
</code></pre>
<p>In order to turn the string input into a list of words and to get rid of any punctuation, I used the replace() and split() methods. The first word of this list would then get appended to a new list called "same", which would hold the words with the same length. A for-loop would then compare the lengths of the words one by one, and either append them to this list if their lengths match, or clear the list if they don't.</p>
<pre><code>if len(words[x]) == len(words[x+1]):
~~~~~^^^^^
IndexError: list index out of range
</code></pre>
<p>This is the problem I keep getting, and I just can't understand why the index is out of range.</p>
<p>I will be very grateful for any help with solving this issue and fixing the program. Thank you in advance.</p>

<pre><code>def paren(s, cnt=0):
if s == '':
return True
if s[0] == '(':
return paren(s[1:], cnt + 1)
elif s[0] == ')':
return paren(s[1:], cnt - 1)
return cnt == 0
</code></pre>
<p>So this code works for all cases if there is the same number of "(" and ")".
But for example it doesn't work for "))(( ".
how can I modify the code for this to work that for every opening bracket there is a closing one, then it returns True.</p>
