<p>I want to change the text of a button using the onclick property, but the value of the parameter 'text' it's appearing when i load the page. Also when i click the button it's text changes to 'undefined'.</p>
<p>That's the code (I starded with Javascript like a week ago so it's probably really bad):</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-js lang-js prettyprint-override"><code>function changeText(text) {
let btn = document.querySelector('button#btn')
btn.innerHTML = text
}
changeText('new text')</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code><button id="btn" onclick="changeText()"></button></code></pre>
</div>
</div>
</p>

<p>My problem: I have a known root node that I'm starting with and a specific other target node that I'm trying to find the shortest path to. I'm trying to write Python code to implement the <a href="https://www.geeksforgeeks.org/iterative-deepening-searchids-iterative-deepening-depth-first-searchiddfs/" rel="nofollow noreferrer">Iterative Deepening Breadth-First Search</a> algo, up to some max depth (say, 5 vertices).</p>
<p>However, there are two features that (I believe) make this problem unlike virtually all the other SO questions and/or online tutorials I've been able to find so far:</p>
<ol>
<li><p><strong>I do not yet know the structure of the tree at all</strong>: all I know is that both the root and target nodes exist, as do many other unknown nodes. The root and target nodes could be separated by one vertice, by 5, by 10, etc. Also, the tree is not binary: any node can have none, one, or many sibling nodes.</p>
</li>
<li><p>When I successfully find a path from the root node to the target node, I need to return the shortest path between them. (Most of the solutions I've seen involve returning the <strong>entire</strong> traversal order required to locate a node, which I don't need.)</p>
</li>
</ol>
<p>How would I go about implementing this? My immediate thought was to try some form of recursion, but that seems much better-suited to Depth-First Search.</p>
<p>TLDR: In the example tree below (apologies for ugly design), I want to traverse it from Root to Target in alphabetical order. (This should result in the algorithm skipping the letters K and L, since it will have found the Target node immediately after J.) I want the function to return:</p>
<p><code>[Root, B, E, H, Target]</code></p>

<p>I've wrote the following implementation of a Barrier using atomics only:</p>
<pre class="lang-rust prettyprint-override"><code>use std::sync::atomic::{AtomicUsize, Ordering};
pub struct Barrier {
pub done: AtomicUsize,
pub tids: usize,
}
impl Barrier {
pub fn new(tids: usize) -> Barrier {
Barrier {
done: AtomicUsize::new(0),
tids,
}
}
pub fn wait(&self) {
let done = self.done.fetch_add(1, Ordering::SeqCst);
if done + 1 == self.tids {
self.done.store(0, Ordering::SeqCst);
} else {
while self.done.load(Ordering::SeqCst) != 0 {}
}
}
}
</code></pre>
<p>It doesn't work as expected. For example,</p>
<pre><code>// inside threads loop
barrier.wait();
println!("a");
barrier.wait();
println!("b");
</code></pre>
<p>Intuitively, it should work, since, once <code>.wait()</code> is called, it will hang on the <code>while</code> loop, breaking free from it after all the threads have called <code>.wait()</code>, and resetting the counter for the next <code>.wait()</code>. Instead, eventually it will hang. Below is an usage example:</p>
<pre class="lang-rust prettyprint-override"><code>fn main() {
println!("Hello, world!");
let barrier = &Barrier::new(10);
std::thread::scope(|s| {
for tid in 0 .. 10 {
s.spawn(move || {
loop {
barrier.wait();
println!("{} a", tid);
barrier.wait();
println!("{} b", tid);
}
});
}
});
}
</code></pre>

<p>I'm implementing a Laravel API + React SPA with Sanctum authentication.</p>
<p>With Sanctum, before requesting the actual login route, you need to send a request to /sanctum/csrf-cookie 'to initialize csrf protection'.</p>
<p>Currently I have this RTK Query api:</p>
<pre><code>import { createApi, fetchBaseQuery } from "@reduxjs/toolkit/query/react";
import { API_HOST } from "./config";
export const authApi = createApi({
reducerPath: "authApi",
baseQuery: fetchBaseQuery({
baseUrl: `${API_HOST}`,
}),
endpoints: (builder) => ({
initCsrf: builder.mutation<void, void>({
query() {
return {
url: "sanctum/csrf-cookie",
credentials: "include",
headers: {
"X-Requested-With": "XMLHttpRequest",
"Content-Type": "application/json",
Accept: "application/json",
},
};
},
}),
loginUser: builder.mutation<{ access_token: string; status: string }, { username: string; password: string }>({
query(data) {
return {
url: "login",
method: "POST",
body: data,
credentials: "include",
headers: {
"X-Requested-With": "XMLHttpRequest",
"Content-Type": "application/json",
Accept: "application/json",
},
};
},
async onQueryStarted(args, { dispatch, queryFulfilled }) {
try {
await queryFulfilled;
} catch (err) {
console.error(err);
}
},
}),
logoutUser: builder.mutation<void, void>({
query() {
return {
url: "logout",
credentials: "include",
};
},
}),
}),
});
export const { useLoginUserMutation, useLogoutUserMutation, useInitCsrfMutation } = authApi;
</code></pre>
<p>Then in my login page, when the user clicks the login button, I call:</p>
<pre><code>const onSubmitHandler: SubmitHandler<LoginInput> = (values) => {
initCsrf()
.then(() => {
loginUser(values);
})
.catch((err) => {
console.error(err);
});
};
</code></pre>
<p>The first request is working and sets the cookie but the second returns with a 419 CSRF Token mismatch exception.</p>
<p>Examining the requests, the login request contains the XSRF-TOKEN cookie with the token that I got in the first request so it should work ok.</p>
<p>This worked before with Axios using the same structure (first request to establish the cookie and the second including the cookie).</p>

<p>Haven't program for a while, but I have this game project where I need to randomized who will be player 1 and player 2 and I need to use a user-defined function because it will be part of a bigger function. Player 1 and 2 should reflect whaat will be printed above. How can I improve my code? I also cannot use global variables.</p>
<pre><code>#include<stdio.h>
int randomColor(int nRandom, int nRed, int nBlue)
{
srand(time(NULL));
nRandom = (rand()%2);
switch (nRandom)
{
case 0:
nRed = 1;
nBlue = 2;
printf("\n\n\tPlayer %d = Red\n", nRed);
printf("\tPlayer %d = Blue\n", nBlue);
break;
case 1:
nRed = 2;
nBlue = 1;
printf("\n\n\tPlayer %d = Blue\n", nRed);
printf("\tPlayer %d = Red\n", nBlue);
break;
}
}
int main()
{
int nRandom, nRed, nBlue;
randomColor(nRandom, nRed, nBlue);
printf("\nPlayer %d (R) turn", nRed);
printf("\nPlayer %d (B) turn", nBlue);
}
</code></pre>

<p>I want to create a Java UDF in a snowflake worksheet in order to query GeoIp2 library and get the ISO code of a given IP. I have '@AWS_CSV_STAGE/lib/geoip2-2.8.0.jar','@AWS_CSV_STAGE/geodata/GeoLite2-City.mmdb'
already staged. How can i direct the function handler to the method that creates the Database Reader as explained here in the documentation for Java:
<a href="https://dev.maxmind.com/geoip/geolocate-an-ip/databases?lang=en#1-install-the-geoip2-client-library" rel="nofollow noreferrer">https://dev.maxmind.com/geoip/geolocate-an-ip/databases?lang=en#1-install-the-geoip2-client-library</a>
in general how can i achieve this whole thing below in my udf?</p>
<pre><code>File database = new File("/path/to/maxmind-database.mmdb")
DatabaseReader reader = new DatabaseReader.Builder(database).build();
InetAddress ipAddress = InetAddress.getByName("128.101.101.101");
CityResponse response = reader.city(ipAddress);
Country country = response.getCountry();
</code></pre>
<p>so far i wrote this but of course it's not working:
anyway i couldn't find much material about how to tackle this kind of problem.</p>
<pre><code>CREATE OR REPLACE FUNCTION GEO()
returns varchar not null
language java
imports = ('@AWS_CSV_STAGE/lib/geoip2-2.8.0.jar','@AWS_CSV_STAGE/geodata/GeoLite2-City.mmdb')
handler = 'DatabaseReader.Builder';
SELECT GEO();
</code></pre>
<p>basically what i want to achieve is to call the UDF on a column of ip address table and get the country code in another column for each ip address.</p>

<p>I've tried to do it using something like:</p>
<pre><code>=UNIQUE(query(J2:L,"select J, K, MAX(L) where K matches 'Pending' or K matches 'Finished' group by J, K, L"))
</code></pre>
<p>but it doesn't get the unique values, as the expected result shows:</p>

<p>This code is supposed to provide contrasting fg and bg color codes, However there's a bug:</p>
<pre class="lang-js prettyprint-override"><code>function randomColorPair() {
const bg = '#' + Math.floor(Math.random() * 16777215).toString(16);
let fg = '#' + Math.floor(Math.random() * 16777215).toString(16);
while (Math.abs(parseInt(bg.substring(1), 16) - parseInt(fg.substring(1), 16)) < 0x777777) {
fg = '#' + Math.floor(Math.random() * 16777215).toString(16);
}
return [bg, fg];
}
console.log(randomColorPair());
console.log(randomColorPair());
console.log(randomColorPair());
console.log(randomColorPair());
console.log(randomColorPair());
console.log(randomColorPair());
console.log(randomColorPair());
console.log(randomColorPair());
console.log(randomColorPair());
console.log(randomColorPair());
console.log(randomColorPair());
console.log(randomColorPair());
console.log(randomColorPair());
</code></pre>
<p>So this function works great, except occassionaly either the bg or fg will only be 4 or 5 characters. Something buggy but it needs to always be six characters for a hex color code.</p>

<p>I have a calculation someting like the following:</p>
<pre class="lang-clj prettyprint-override"><code>;; for sake of simplicity we use round numbers
(def data [{:a 1} {:a 10} {:a 100}])
(reduce - 0.0 (map :a data))
</code></pre>
<p>And it evaluates to <code>-111.0</code>. I want to do the transformation with a transducer to speed it up a bit by preventing unnecessary allocations:</p>
<pre><code>(transduce (map :a) - 0.0 data)
</code></pre>
<p>However, the signum of the result changed to positive! Apparently it does not matter if I use <code>+</code> or <code>-</code> as the reducer in the expression, as the form will evaluate to <code>+111.0</code> in both cases.</p>
<p>This is surprising to me, why did the introduction of <code>transduce</code> change the semantics, what am I missing here?</p>
<p>(the strange behaviour happens with <code>*</code> and <code>/</code> too!)</p>

<p>I am currently looking at something similar to <code>df</code> what I would like to be able to do is produce soemthing that looks like <code>df2</code>. Where the specified column values are compared next to eachother, the number of specific occurences are counted, and the count is places into a new column in a new dataframe.</p>
<p>For example: in <code>df</code> the combination 1, 5, and 9 occur 3 times.</p>
<pre><code>df <- data.frame( col1 = c(1,2,3,4,1,2,3,4,1),
col2 = c(5,6,7,8,5,6,7,8,5),
col3 = c(9,10,11,12,9,10,11,13,9))
</code></pre>
<pre><code>df2 <- data.frame( col1 = c(1,2,3,4,4),
col2 = c(5,6,7,8,8),
col3 = c(9,10,11,12,13),
count = c(3,2,2,1,1))
</code></pre>
<p>I tried using dplyr</p>
<pre><code>df2 <- df %>%
distinct(col1,col2, col3) %>%
group_by(col3) %>%
summarize("count" = n())
</code></pre>
<p>with no success</p>

<p>I am python newbie and have read countless answers here and in other sources, on how to create folders if they do not exist and move files there. However, still I cannot bring it to work.</p>
<p>So what I want to do is the following:
Keep my downloads folder clean. I want to run the script, it is supposed to move all files to matching extension name folders. If the folder already exists, it does not have to create it.</p>
<p>Problems: I want to be able to run the script as often as I want while keeping the newly created folders there. However, then the whole os.listdir part does not work because folders have no file extensions. I tried to solve this by leaving out folders but it does not work as well.</p>
<p>I would appreciate any help!</p>
<pre><code>from os import scandir
import os
import shutil
basepath = r"C:\Users\me\Downloads\test"
for entry in scandir(basepath):
if entry.is_dir():
continue
files = os.listdir(r"C:\Users\me\Downloads\test")
ext = [f.rsplit(".")[1] for f in files]
ext_final = set(ext)
try:
[os.makedirs(e) for e in ext_final]
except:
print("Folder already exists!")
for file in files:
for e in ext_final:
if file.rsplit(".")[1]==e:
shutil.move(file,e)
</code></pre>

<p>Let's say I have an array of variables:</p>
<pre><code>let fruits = [apple, orange, banana];
</code></pre>
<p>These variables target specific DOM elements</p>
<pre><code>apple = document.getElementById("apple");
orange = document.getElementById("orange");
banana = document.getElementById("banana");
</code></pre>
<p>I also happen to have another set of variables that basically have "Rot" added to them</p>
<pre><code>appleRot = document.getElementById("appleRot");
orangeRot = document.getElementById("appleRot");
bananaRot = document.getElementById("appleRot");
</code></pre>
<p>Is it possible to loop through the existing array and add "Rot" to each element so they target the other set of existing variables?</p>
<pre><code>let fruits = [apple, orange, banana];
let fruitsRot = fruits.map((x) => x + "Rot");
</code></pre>
<p>is something like this possible without the result being a string but an array of elements that happen to target the second set of variables?</p>

<p>I have an api with details of a farm and I want to show them in different components using an id. Like the data is used in many components and I want to use Context API to display the data in the components.</p>
<p>So here is the code that fetches the data</p>
<pre><code>let navigate = useNavigate();
const [farm, setFarm] = useState('');
const { username } = useParams();
const { farmId } = useParams();
const [isLoading, setIsLoading] = useState(true);
const user = React.useContext(UserContext);
useEffect(() => {
let isMounted = true;
axios.get(`/api/farm/${username}/${farmId}`).then(res => {
if (isMounted) {
if (res.data.status === 200) {
setFarm(res.data.farm);
setIsLoading(false);
console.warn(res.data.farm)
}
else if (res.data.status === 404) {
navigate('/');
toast.error(res.data.message, "error");
}
}
});
return () => {
isMounted = false
};
}, []);
</code></pre>
<p>The username is okay because I will use the user context to get the user details.
Now, how do Use this from a context into the components, because I have tried, and it is not working.</p>

<p>This script is applied to a button on the worksheet.</p>
<p>The question is: how do I make every comma typed in this spreadsheet be converted into another sign, like <code>#</code> before generating the <code>.CSV</code> file in the folder?</p>
<p>I would also like to know if instead of generating 1 file in the folder it is possible to generate 2 files, each with a name.</p>

<p>I have a project management application built with React and GraphQL for which the Github repo can be found <a href="https://github.com/jevoncochran/managr" rel="nofollow noreferrer">here</a>. One of the functionalities allows for deleting a project.</p>
<p><a href="https://i.stack.imgur.com/l0Sl2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/l0Sl2.png" alt="enter image description here" /></a></p>
<p>I am trying to update the cache when I delete an individual project.</p>
<pre><code>const [deleteProject] = useMutation(DELETE_PROJECT, {
variables: { id: projectId },
update(cache, { data: { deleteProject } }) {
const { projects } = cache.readQuery({ query: GET_PROJECTS });
cache.writeQuery({
query: GET_PROJECTS,
data: {
projects: projects.filter(
(project) => project.id !== deleteProject.id
),
},
});
},
onCompleted: () => navigate("/"),
});
</code></pre>
<p>However, when I attempt to do so, I am getting the following error: <code>Error: Cannot destructure property 'projects' of 'cache.readQuery(...)' as it is null</code></p>
<p>Can someone help me figure out what's going on? This is what the getProjects query looks like:</p>
<pre><code>const GET_PROJECTS = gql`
query getProjects {
projects {
id
name
description
status
}
}
`;
</code></pre>
<p>Here is the root query:</p>
<pre><code>const RootQuery = new GraphQLObjectType({
name: "RootQueryType",
fields: {
projects: {
type: new GraphQLList(ProjectType),
resolve(parent, args) {
return Project.find();
},
},
project: {
type: ProjectType,
args: { id: { type: GraphQLID } },
resolve(parent, args) {
return Project.findById(args.id);
},
},
clients: {
type: new GraphQLList(ClientType),
resolve(parent, args) {
return Client.find();
},
},
client: {
type: ClientType,
args: { id: { type: GraphQLID } },
resolve(parent, args) {
return Client.findById(args.id);
},
},
},
});
</code></pre>

<p>While developing my personal portfolio using Next.js, I ran into an error where the prop "children" was not working. I am using tsx.</p>
<p>Layout.tsx</p>
<pre><code>import styles from "./layout.module.css";
export default function Layout({ children, ...props }) {
return (
<>
<main className={styles.main} {...props}>{children}</main>
</>
);
}
</code></pre>
<p>I tried using other props, defining the props, like I was from tutorials online, but none of them worked. ;(</p>

<p>Instead of images, I want to place colors in those spots.</p>
<p><a href="https://jsfiddle.net/rza8v51x/" rel="nofollow noreferrer">https://jsfiddle.net/rza8v51x/</a></p>
<p>The images are set in a grid layout, and I want to remove them and add colors.</p>
<p>In place of the images I want to add colors in those spots.</p>
<p>That is all I am trying to do in the code.</p>
<p>Replace the images with colors.</p>
<p>How would this be done?</p>

<p>req.body returns undefined.
Here is my code.</p>
<pre><code>const express = require('express');
const app = express();
const courses = [
{ id: 1, name: 'course1'},
{ id: 2, name: 'course2'},
{ id: 3, name: 'course3'},
];
app.use(express.json());
app.get('/api/courses', (req, res) => {
res.send(courses);
});
app.post('/api/courses', (req, res) =>{
const course = {
id: courses.length + 1,
name: req.body.name
};
courses.push(course)
res.send(course)
});
const port = process.env.PORT || 3000
app.listen(port, () => console.log(`Listening on port ${port}...`))
</code></pre>
<p>Using postman to post an object, for example</p>
<pre><code>{
"name" : "newCourse"
}
</code></pre>
<p>will return only id, not returning both the expected id and name. Console.log(course.name) returns undefined.
This code is from a tutorial by Programming with Mosh <a href="https://www.youtube.com/watch?v=pKd0Rpw7O48" rel="nofollow noreferrer">https://www.youtube.com/watch?v=pKd0Rpw7O48</a> Time: 33 min
I'm a beginner in node and express, any clue and explaination on why this doesn't work as it did in the tutorial?</p>

<p>I want to enter an item into the entry box press a button and add the item to the list changing the list permanently, however I cannot seem to make a permanent change to the list. The program always returns "[]" and never the updated list. Is there a way I can do this?</p>
<p>I have tested and there are no issues involving extracting text from the entry box and adding It to the list. The only problem is making the change permanent.</p>
<p>here is the code:</p>
<pre><code>from tkinter import *
window = Tk()
names = []
ent = Entry(window)
ent.pack()
def change():
names.append(ent.get())
btn = Button (window, command = change )
btn.pack()
print(names)
window.mainloop()
</code></pre>
<p>why is the response always "[]" and not the updated list</p>

<p>I want to merge df1 and df2, by pulling in only the numerics from df2 into df1? This would be a nested (Lookup(xlookup) in excel, but Im having difficulty working this in r? Any info would be much appreciated.</p>
<pre><code>df1 <- data.frame(Names = c("A","B","C","D","E"),
Rank = c("R1","R3","R4","R2","R5"),
Time_in_rank = c(2,4.25,3,1.5,5))
df2 <- data.frame(Time_in_rank =c(0,1,2,3,4),
R1 =c(20000,25000,30000,35000,40000),
R2 =c(45000,50000,55000,60000,65000),
R3 =c(70000,75000,80000,85000,90000),
R4 =c(95000,96000,97000,98000,100000),
R5 =c(105000,107000,109000,111000,112000))
Desired output
Names Time_in_rank Rank Salary
A 2 R1 30000
B 4.25 R3 90000
C 3 R4 98000
</code></pre>

<p>Short backstory: I am trying to create a <code>Readable</code> stream based on data chunks that are emitted back to my server from the client side with WebSockets. Here's a class I've created to "simulate" that behavior:</p>
<pre class="lang-js prettyprint-override"><code>class DataEmitter extends EventEmitter {
constructor() {
super();
const data = ['foo', 'bar', 'baz', 'hello', 'world', 'abc', '123'];
// Every second, emit an event with a chunk of data
const interval = setInterval(() => {
this.emit('chunk', data.splice(0, 1)[0]);
// Once there are no more items, emit an event
// notifying that that is the case
if (!data.length) {
this.emit('done');
clearInterval(interval);
}
}, 1e3);
}
}
</code></pre>
<p>In this post, the <code>dataEmitter</code> in question will have been created like this.</p>
<pre class="lang-js prettyprint-override"><code>// Our data is being emitted through events in chunks from some place.
// This is just to simulate that. We cannot change the flow - only listen
// for the events and do something with the chunks.
const dataEmitter = new DataEmitter();
</code></pre>
<p>Right, so I initially tried this:</p>
<pre class="lang-js prettyprint-override"><code>const readable = new Readable();
dataEmitter.on('chunk', (data) => {
readable.push(data);
});
dataEmitter.once('done', () => {
readable.push(null);
});
</code></pre>
<p>But that results in this error:</p>
<pre><code>Error [ERR_METHOD_NOT_IMPLEMENTED]: The _read() method is not implemented
</code></pre>
<p>So I did this, implementing <code>read()</code> as an empty function:</p>
<pre class="lang-js prettyprint-override"><code>const readable = new Readable({
read() {},
});
dataEmitter.on('chunk', (data) => {
readable.push(data);
});
dataEmitter.once('done', () => {
readable.push(null);
});
</code></pre>
<p>And it works when piping into a write stream, or sending the stream to my test API server. The resulting <code>.txt</code> file looks exactly as it should:</p>
<pre><code>foobarbazhelloworldabc123
</code></pre>
<p>However, I feel like there's something quite wrong and hacky with my solution. I attempted to put the listener registration logic (<code>.on('chunk', ...)</code> and <code>.once('done', ...)</code>) within the <code>read()</code> implementation; however, <code>read()</code> seems to get called multiple times, and that results in the listeners being registered multiple times.</p>
<p>The Node.js documentation says <a href="https://nodejs.org/api/stream.html#readable_readsize" rel="nofollow noreferrer">this</a> about the <code>_read()</code> method:</p>
<blockquote>
<p>When readable._read() is called, if data is available from the resource, the implementation should begin pushing that data into the read queue using the this.push(dataChunk) method. _read() will be called again after each call to this.push(dataChunk) once the stream is ready to accept more data. _read() may continue reading from the resource and pushing data until readable.push() returns false. Only when _read() is called again after it has stopped should it resume pushing additional data into the queue.</p>
</blockquote>
<p>After dissecting this, it seems that the consumer of the stream calls upon <code>.read()</code> when it's ready to read more data. And when it is called, data should be pushed into the stream. But, if it is not called, the stream should not have data pushed into it until the method is called again (???). So wait, does the consumer call <code>.read()</code> when it is ready for more data, or does it call it after each time <code>.push()</code> is called? Or both?? The docs seem to contradict themselves.</p>
<p>Implementing <code>.read()</code> on <code>Readable</code> is straightforward when you've got a basic resource to stream, but what would be the proper way of implementing it in this case?</p>
<p>And also, would someone be able to explain in better terms what the <code>.read()</code> method is on a deeper level, and how it should be implemented?</p>
<p>Thanks!</p>
<p><strong>Response to the answer:</strong></p>
<p>I did try registering the listeners within the <code>read()</code> implementation, but because it is called multiple times by the consumer, it registers the listeners multiple times.</p>
<p>Observing this code:</p>
<pre class="lang-js prettyprint-override"><code>const readable = new Readable({
read() {
console.log('called');
dataEmitter.on('chunk', (data) => {
readable.push(data);
});
dataEmitter.once('done', () => {
readable.push(null);
});
},
});
readable.pipe(createWriteStream('./data.txt'));
</code></pre>
<p>The resulting file looks like this:</p>
<pre><code>foobarbarbazbazbazhellohellohellohelloworldworldworldworldworldabcabcabcabcabcabc123123123123123123123
</code></pre>
<p>Which makes sense, because the listeners are being registered multiple times.</p>

<p>Hello, I am trying to use map() to map the products array to its corresponding prices but the function returns undefined</p>
<p>I have tried using the debugger to step through the code and there are values stored in the output variable as it iterates through the array but in the end it returns undefined.
I am only new to programming and i cant see why this happens.
Thanks alot</p>

<p>I have a feeling this question already exists, just can't find it.
Is there a way to take a 2d array with x rows and 2 columns and merge multiple values into one row based on it having the same element in the first column?</p>
<pre><code>[['Needs Work', 'Joe'], ['Needs Work', 'Jill'], ['Needs Work', 'Jack'], ['Complete', 'Sean'], ['Complete', 'Joe'], ['Not Started', 'Laura'], ['Needs Work', 'Jack']]
</code></pre>
<p>So that it looks like this</p>
<pre><code>[ [ 'Needs Work', 'Joe,Jill,Jack,Jack' ],
[ 'Complete', 'Sean,Joe' ],
[ 'Not Started', 'Laura' ] ]
</code></pre>

<p>i'm working on react native expo project, i'm trying to build custom ProgressBar, I have state call step if the step increase by 1 then the width value of the view has to increase, if the step decreases then the width value of the view has to decrease, so if the value increase or decrease it seems the view has some animation on it</p>
<pre><code>const ProgressBar =({step , requset}) =>{
const [ steps , setSteps ]= useState(0);
const [accessToken, setAccessToken] = useState(null);
const [ width , setWidth ] = useState(50);
useEffect( ()=> {
const getToken = async ()=>{
const accessToken = await token.get();
setAccessToken(accessToken)}
getToken();
accessToken ?
requset == 1 ? setSteps(6) : setSteps(7)
: setSteps(3)
})
useEffect (()=>{
const newWidth = (step*50);
setWidth(newWidth);
})
return(
<View style={{flexDirection:'row',}} >
<View style={styles.progressBar}>
<Animated.View
onLayout = {e =>{
const newWidth = e.nativeEvent.layout.width;
setWidth(newWidth);
}}
style ={ [styles.progress,{width: width}]}
/>
</View>
<Text style={styles.progressText}>{steps}/{step}</Text>
</View>
)}
</code></pre>
<p>How can I make a mathematical statement that calculates the amount of width increases depend on Total steps?</p>

<p>I'm a beginner with React and I have been coding a project for one of the courses in uni. However, I have been now struggling for quite some time with following error: Uncaught RangeError: Maximum call stack size exceeded. I have tried to find a solution with no luck.</p>
<p>Here is my code for the React component that causes the error:</p>
<p>`</p>
<pre class="lang-js prettyprint-override"><code>import { Container } from "react-bootstrap"
import { useParams } from "react-router"
import apiService from "../services/apiService"
import { useEffect, useState } from "react"
import Spinner from 'react-bootstrap/Spinner';
const GOOGLE_API_KEY = process.env.REACT_APP_GOOGLE_API_KEY
export const TreeProfile = (props) => {
const [tree, setTree] = useState({})
const [fetching, setFetching] = useState(true)
const [zoom, setZoom] = useState("12")
const [location, setLocation] = useState({latitude: "", longitude: ""})
let { id } = useParams()
const handleZoomChange2 = (event) => {
console.log(event.target.value)
setZoom(event.target.value)
}
console.log("Called TreeProfile")
useEffect(() => {
console.log("id", id)
apiService.getOne(id).then(t => {
console.log("data", t)
setTree(t)
setLocation({latitude: t.location.latitude, longitude: t.location.longitude})
setFetching(false)
})
}, [])
return (

</div>
<button type="button" className="btn btn-primary" >Add update</button>
</Container>
)
}
</code></pre>
<p>`</p>
<p>The error happens every time I try to update the zoom level by sliding the slider, which calls handleZoomChange2 function that sets the state. I have other component in different route with the same functionality and it works fine. However, this one for some reason causes the error constantly.</p>
<p>The apiService fetches the data with axios from the backend, which in turn fetches the data from MongoDB.</p>
<p>I tried to update zoom level by sliding the slider input, which calls on handleZoomChange2 setting a new state to the zoom. However, the code throws an error Maximum call stack size exceeded. Please, help!</p>
<p>Error:</p>

<p>I have recyclerView and after click of card I would like to replace fragments in activity. The problem is I have no access to activity. Here is my code in adapter:</p>
<pre><code>override fun onBindViewHolder(holder: ViewHolder, position: Int) {
val itemsViewModel = mList[position]
holder.tagImage.setImageResource(itemsViewModel.tagImage)
holder.tagName.text = itemsViewModel.tagName
holder.tagDescription.text = itemsViewModel.tagDescription
holder.itemView.setOnClickListener {
Log.d(InTorry.TAG, itemsViewModel.tagName)
val fragment = ProductsFragment()
val transaction = activity?.supportFragmentManager?.beginTransaction()
transaction?.replace(R.id.homeFragmentsContainer, fragment)
//transaction?.disallowAddToBackStack()
transaction?.commit()
}
}
</code></pre>
<p>The above replace code works in fragment but in adapter there is "activity?" error.</p>
<p>Kind Regards</p>
<p>Jack</p>

<p>I have a spreadsheet in Excel that kinda looks like this:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th style="text-align: left;">SubjectID</th>
<th style="text-align: left;">ValidQuestions</th>
<th style="text-align: left;">Name</th>
</tr>
</thead>
<tbody>
<tr>
<td style="text-align: left;">XXX000</td>
<td style="text-align: left;">10</td>
<td style="text-align: left;">Python</td>
</tr>
<tr>
<td style="text-align: left;">CCC111 / TTT222</td>
<td style="text-align: left;">9</td>
<td style="text-align: left;">Data Structure</td>
</tr>
</tbody>
</table>
</div>
<p>.
.
The first column represents the ID code that identifies a certain subject. The second one is the number of valid questions that can be used in a exam. The third one is the name of the subject.</p>
<p>I have another tab that kind looks like this:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>SubjectID</th>
<th>ValidQuestions</th>
</tr>
</thead>
<tbody>
<tr>
<td>XXX000</td>
<td></td>
</tr>
<tr>
<td>CCC111</td>
<td></td>
</tr>
</tbody>
</table>
</div>
<p>But this time, the SubjectId column contains only one value that is not separated by a slash and the ValidQuestions column is empty. I need to fill the second one with values from the first tab. I tried to use VLOOKUP but it's not working. I would appreciate help.</p>

<p>I have to create a JS program that changes the title of a page either every 30 seconds or when the user leaves the page. It depends on the word passed in parameter. I call "linear" the function that allows to change the title every 30 seconds and leaving the one that allows it when the user leaves the page.</p>
<p>The leaving function works well but the linear function executes only the first cell of the message array to display. I tried several alternatives but nothing works, could someone explain my error?
Here is the code</p>
<pre><code>var titles = ["MyTitle","AlsoMyTitle","MyThirdTitle","TheFourth"];
var timeLaps = 1000; // time in miliseconds
var i = 0;
var ogTitle = document.title;
function mainTitle() {
document.title = ogTitle;
}
function newTitle() {
document.title = 'Come Back!';
}
function leaving() {
window.onblur = newTitle;
window.onfocus = mainTitle;
}
function linear(){
if (i == 4) {
i = 0;
}
document.title = titleArray[i];
i++;
}
function main(animType) {
if(animType === "leaving") {
leaving();
} else if (animType === "linear") {
setInterval(() => {
changeTitle('linear')
}, timeLaps);
}
}
main('linear');
</code></pre>
<p>Have a good day!</p>

<p>I am trying to create an xlsx file in the browser and find <a href="https://github.com/exceljs/exceljs" rel="nofollow noreferrer">https://github.com/exceljs/exceljs</a> very powerful. However, I can't find a way how to save my xlsx object to a file. Probably I need to use Buffer, but how to generate a file from it?</p>
<pre><code>const buffer = await workbook.xlsx.writeBuffer();
</code></pre>
<p>This library can generate files in the browser <a href="https://docs.sheetjs.com/docs/" rel="nofollow noreferrer">https://docs.sheetjs.com/docs/</a> but it is not good at building complex fields.</p>

<p>I am following a tutorial which introduced the global JSON object to stringify objects, in the tutorial they mention that this JSON object and it's methods is provided by the browser. I've also looked at the MDN page for JSON and they list it as a standard built in object.</p>
<p>I'm trying to understand if an object such as this is the same as the Date or Math objects and is built into Javascript or is it something extra that is provided by browsers implementing it?</p>

<p>I have following table in Pandas:</p>
<pre><code>index | project | category | period | update | amount
0 | 100130 | labour | 202201 | 202203 | 1000
1 | 100130 | labour | 202202 | 202203 | 1000
2 | 100130 | labour | 202203 | 202203 | 1000
3 | 100130 | labour | 202204 | 202203 | 1000
4 | 100130 | labour | 202205 | 202203 | 1000
</code></pre>
<p>And my final goal is to get table grouped by project and category with summary of amount column but only from month of update until now.
So for example above I will get summary from 202203 until 202205 which is 3000 for project 100130 and category labour.</p>
<p>As a first step I tried following condition:</p>
<pre><code>for index, row in table.iterrows():
if row["period"] < row["update"]
row["amount"] = 0
</code></pre>
<p>But:</p>
<ol>
<li>this iteration is not working</li>
<li>is there some simple and not so time consuming way how to do it? As my table has over 60.000 rows, so iteration not so good idea probably.</li>
</ol>

<p>I am trying to create a date identifier using only if statements and a switch statement that can determine whether an inputted date is valid, what season the date is in and finally whether it is a leap year. I tried to get the component parts working independently first and got two of them working then tried them all together but I still can't get my switch statement working. I want my switch statement to show the season by checking both the day and month to see what season we are in but I'm not sure how to do that. Here is my code:</p>
<pre><code>/* Switch statement to determine season for day and month */
// Using it with a "m" on it's own works, how do I get it working for specific days?
switch (m)
{
case 12:
case 1:
case 2:
if ((m == 12 && d >=21) || (m == 1) || (m == 2) || (m == 3 && m < 21))
printf("The season is Winter.\n");
break;
case 3:
case 4:
case 5:
if ((m == 3 && d >= 21) || (m == 4) || (m == 5) || (m == 6 && d < 21))
printf("The season is Spring.\n");
break;
case 6:
case 7:
case 8:
if ((m == 6 && d >= 21) || (m == 7) || (m == 8) | (m == 9 && d < 21))
printf("The season is Summer.\n");
break;
case 9:
case 10:
case 11:
if ((m == 9 && d >= 21) || (m == 10) || (m == 11) || (m == 12 && d < 21))
printf("The season is Autumn.\n");
default:
break;
}
}
</code></pre>
<p>I tried getting the code working for each part independently, but I'm still unsure about my switch statement. How can I get it working for days as well as months? Is there a way to do it still with a switch statement?</p>
<p>Example Output:</p>
<pre class="lang-none prettyprint-override"><code>20/06/2022 = Spring
21/06/2022 = Summer
</code></pre>

<p>I have some custom jQuery that disappears after paginating. I couldn't figure out how to keep it loaded so I figured I would try to reload it after click but thats not working either.</p>
<p>here is what i was trying to get it to run:</p>
<pre><code>$(document).ready(function() {
$('.pagination>li>a').live("click", function(){
</code></pre>
<p>any ideas how to make this work?</p>
<p>what I would really like is to keep the custom jQuery while paginating, since there could potentially be 2 separate paginations on any given page (displaying notes and activities).</p>

<p>I'm doing some multiple regEX replacements in powershell on a large number of files and would like to only write the file if any replacements were actually made.</p>
<p>For example if I do:</p>
<pre><code>($_ | Get-Content-Raw) -Replace 'MAKEUPS', 'Makeup' -Replace '_MAKEUP', 'Makeup' -Replace 'Make up', 'Makeup' -Replace 'Make-up', 'Makeup' -Replace '"SELF:/', '"' |
Out-File $_.FullName -encoding ASCII
</code></pre>
<p>I only want to write the file if it found anything to replace. Is this possible, maybe with a count or boolean operation?</p>
<p>I did think maybe to check the length of the string before and after but was hoping for a more elegant solution, so I thought I'd ask the experts!</p>

<p>I was trying to find the time complexity of this nested loop</p>
<pre><code>for (i = 1; i <= n; i++) {
for (j = 1; j <= n; j++) {
n--;
x++;
}
}
</code></pre>
<p>If there wasn't a <code>n--</code> it would be <code>n*n</code> , O(n<sup>2</sup>) right?</p>
<p>But what if <code>n</code> reduces every time second loop runs?</p>
<p>What's the time complexity and big O of this nested loop?</p>
<p>If I consider n = 5, x equals 4, the second loop runs 4 time</p>

<p>i would like to set a df value between two values x_lim(0,2) to True.</p>
<p>I would like to get a df that looks like this:</p>
<pre><code>x | y | z
0 | 7 | True
1 | 3 | True
2 | 4 | True
3 | 8 | False
</code></pre>
<p>i tried :</p>
<pre><code>def set_label(df, x_lim, y_lim, variable):
for index, row in df.iterrows():
for i in range(x_lim[0],x_lim[1]):
df['Label'] = variable.get()
print(df)
</code></pre>
<p>could anyone help me to solve this problem ?</p>

<p>im trying to write a function that returns the length of the longest run of repetition in a given list</p>
<p>Here is my code:
`</p>
<pre><code>def longest_repetition(a):
longest = 0
j = 0
run2 = 0
while j <= len(a)-1:
for i in a:
run = a.count(a[j] == i)
if run == 1:
run2 += 1
if run2 > longest:
longest = run2
j += 1
run2 = 0
return longest
print(longest_repetition([4,1,2,4,7,9,4]))
print(longest_repetition([5,3,5,6,9,4,4,4,4]))
3
0
</code></pre>
<p>`</p>
<p>The first test function works fine, but the second test function is not counting at all and I'm not sure why. Any insight is much appreciated</p>
<p>Edit: Just noticed that the question I was given and the expected results are not consistent. So what I'm basically trying to do is find the most repeated element in a list and the output would be the number of times it is repeated. That said, the output for the second test function should be 4 because the element '4' is repeated four times (elements are not required to be in one run as implied in my original question)</p>

Then I used a for loop to iterate through the list and print the letters not in the list</p>

<p>Hello I know that I have the code right. I want to destroy the material when my player goes on them. I don't know why I can't destroy them. I have put only to my materials box collider with X= 1 Y=1 Z=1.I don't understand why I can't destroy them. The material I gave it also as a tag. Instead of my player destroy those material he pass through them..I have a <code>RigidBody</code> on the player.</p>
<pre><code>void OnCollisionEnter ( Collision collision )
{
if ( collision.gameObject.tag == "material" )
{
Destroy ( collision.gameObject );
}
}
</code></pre>

<p>I want the if statement working after the 30 seconds but that isn't the case right now. I heard people recommend threading but that's just way too complicated for me.</p>
<pre><code>import os
import time
print('your computer will be shutdown if you dont play my game or if you lose it')
shutdown = input("What is 12 times 13? you have 30 seconds.")
time.sleep(30)
if shutdown == '156':
exit()
elif shutdown == '':
print('you didnt even try') and os.system("shutdown /s /t 1")
else:
os.system("shutdown /s /t 1")
</code></pre>
<p>I tried threading already but that is really complicated and I'm expecting to print you didn't even try and shutdown after the 30 seconds if you didn't input anything</p>

<p>Until now, I have used <a href="https://doc.rust-lang.org/std/fs/fn.read_to_string.html" rel="nofollow noreferrer"><code>std::fs::read_to_string</code></a> and then <a href="https://doc.rust-lang.org/std/string/struct.String.html#method.lines" rel="nofollow noreferrer"><code>String.lines</code></a>'s <a href="https://doc.rust-lang.org/std/str/struct.Lines.html" rel="nofollow noreferrer"><code>std::str::Lines</code></a> (which is an <code>Iterator<Item = &str></code>) to read a file "line by line". This obviously reads the whole file into memory, which is not ideal.</p>
<p>So, there's <a href="https://doc.rust-lang.org/std/io/trait.BufRead.html#method.lines" rel="nofollow noreferrer"><code>BufRead.lines()</code></a> to read a file truly line by line. This returns <a href="https://doc.rust-lang.org/std/io/struct.Lines.html" rel="nofollow noreferrer"><code>std::io::Lines</code></a> (which is an <code>Iterator<Item = Result<String>></code>).</p>
<p>How do I convert from one iterator type to the other without <code>collect</code>ing first?</p>

<p>Is there a way I can call a function in the return section of React? kind of like how in JS I can just call a function by <code>functionName()</code> ?</p>
<p><strong>WHAT EXACTLY AM I TRYING TO ACCOMPLISH?</strong>
What I am wanting to do in this bakery game is when the player hits $5, the "Purchase Easy Bake Oven" pops up and it will cost them $25 to purchase (At this time I do not necessarily care about the math mathing, I just care for functionality). Once the player decides to purchase, this section disappears and is replaced with "Easy bake Oven" With a button that says $5 where at this point, every time the button is clicked my total increases by 5.</p>
<p><strong>WHAT HAVE I TRIED?</strong>
I feel like this should be done with an onClick event to switch from <code>const [showEZBake, setShowEZBake] = useState(false)</code> to <code>useState(True)</code>. I currently have a Turnary (or whatever you call it), but I feel like this is incorrect because I need to change the state as stated before. I have also attempted to create an if statement inside of a function where I would add an h1 element, but that did not work. Even if it did, my main issue would still be there and that is how to call a function inside of a return.</p>
<p><strong>SUMMARY:</strong>
I want the "Purchase Oven" text and $5 button to be replaced with Oven and $2 button AFTER the button was clicked.</p>

<p>I am trying to learn pattern matching with regex, the course is through coursera and hasn't been updated since python 3 came out so the instructors code is not working correctly.</p>
<p>Here's what I have so far:</p>
<pre><code># example Wiki data
wiki= """There are several Buddhist universities in the United States. Some of these have existed for decades and are accredited. Others are relatively new and are either in the process of being accredited or else have no formal accreditation. The list includes:
• Dhammakaya Open University – located in Azusa, California,
• Dharmakirti College – located in Tucson, Arizona
• Dharma Realm Buddhist University – located in Ukiah, California
• Ewam Buddhist Institute – located in Arlee, Montana
• Naropa University - located in Boulder, Colorado
• Institute of Buddhist Studies – located in Berkeley, California
• Maitripa College – located in Portland, Oregon
• Soka University of America – located in Aliso Viejo, California
• University of the West – located in Rosemead, California
• Won Institute of Graduate Studies – located in Glenside, Pennsylvania"""
pattern=re.compile(
r'(?P<title>.*)' # the university title
r'(-\ located\ in\ )' #an indicator of the location
r'(?P<city>\w*)' # city the university is in
r'(,\ )' #seperator for the state
r'(?P<state>\w.*)') #the state the city is in)
for item in re.finditer(pattern, wiki, re.VERBOSE):
print(item.groupdict())
</code></pre>
<p>Output:</p>
<pre><code>Traceback (most recent call last):
File "/Users/r..., line 194, in <module>
for item in re.finditer(pattern, wiki, re.VERBOSE):
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/re/__init__.py", line 223, in finditer
return _compile(pattern, flags).finditer(string)
^^^^^^^^^^^^^^^^^^^^^^^^
File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/re/__init__.py", line 282, in _compile
raise ValueError(
ValueError: cannot process flags argument with a compiled pattern
</code></pre>
<p>I only want a dictionary with the university name, the city and the state. If I run it without re.VERBOSE, only one school shows up and none of the rest are there.
I am somewhat new to python and don't know what to do about these errors</p>

<p>I have the following timelines :</p>
<pre><code>
7 a.m --------------------- 12 a.m. 2 am .................. 10 a.m
10-------11 3------5
closed closed
</code></pre>
<pre><code>the output should be the non-intersecting time ranges:
7-10 a.m, 11 -12 a.m, 2-3 p.m, 5-10 p.m
</code></pre>
<p>I tried to minus and subtract method for Ranges but didn't work
A tricky part could be the following case</p>
<pre><code>
7 a.m --------------------- 12 a.m. 2 am .................. 10 a.m
10----------------------------------------5
closed
</code></pre>
<pre><code>the output should be the non-intersecting time ranges:
7-10 a.m, 5-10 p.m
</code></pre>
<p>Any Idea for kotlin implementation?</p>

<p>Assume I have a list of values, for example:</p>
<pre><code>limits = [10, 6, 3, 5, 1]
</code></pre>
<p>For every item in <code>limits</code>, I need to generate a random number less than or equal to the item. However, the catch is that the sum of elements in the new random list must be equal to a specified total.</p>
<p>For example if <code>total = 10</code>, then one possible random list is:</p>
<pre><code>random_list = [2, 1, 3, 4, 0]
</code></pre>
<p>where you see <code>random_list</code> has same length as <code>limits</code>, every element in <code>random_list</code> is less than or equal to the corresponding element in <code>limits</code>, and <code>sum(random_list) = total</code>.</p>
<p>How to generate such a list? I am open (and prefer) to use numpy, scipy, or pandas.</p>

<p>New-ish to R and I feel like this has a simple solution, but I can't figure it out.</p>
<p>I have 59 excel files that I want to combine. However, 4 of the columns have a mix of dates and <code>NA</code>'s (depending on if the study animal is a migrant or not) so R won't let me combine them because some are numeric and some are character. I was hoping to read all of the excel files into R, convert those 4 columns in each file to <code>as.character</code>, and then merge them all. I figured a loop could do this.</p>
<p>Anything I find online has me typing out the name for each read file, which I don't really want to do for 59 files. And once I do have them read into R and those columns converted, can I merge them from R easily? Sorry if this is simple, but I'm not sure what to do that would make this easier.</p>

<p>I am testing keycloak for learning purposes. I am testing the client credentials flow token endpoint to return a jwt for rest api use.</p>
<p>The endpoint returns an <code>access_token</code> and a <code>refresh_token</code> (refresh token is disabled by default unless I enable it in console for the client). I can call the same token endpoint with a refresh token generated from the first client credentials call but it still requires a client secret.</p>
<p>Is it not possible to regenerate an access token in the client credentials flow with just a refresh token?</p>
<p>If not why would I ever bother to pass a <code>grant_type</code> of <code>refresh_token</code> - wouldn't I just call the client_credential flow again since they both require a client secret? I have to guess the answer will be that refresh tokens don't make sense to be used with client_credential flows?</p>
<p>token parameters:</p>

<p>I designed the scrollable cards. The cards are only for mobile screens. The current issue is that more data gets encapsulated inside the scrollable wrapper as the content grows. No matter how long the content is, I want the div's height to increase. Is there a fix for this design that makes the card's height rise in proportion to its contents?</p>
<p>The <code>read more</code> functionality is implemented, but I didn't add it to the snippet. By default, all the content will be the same. But on <code>read more</code>, the content can vary. So, I want the design to be fixed so <code>read more</code> content does not affect the card.</p>
<p>By default:</p>
<p><a href="https://i.stack.imgur.com/AN6NJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/AN6NJ.png" alt="enter image description here" /></a></p>
<p>On clicking read more/content increases:</p>

<p>Im trying to get this code for image browsing then cropping the browsed image working:</p>
<p>This is the supposed code to be working:</p>
<pre><code>import "./styles.css";
import React, { useState } from "react";
import ReactCrop from 'react-image-crop';
import 'react-image-crop/dist/ReactCrop.css'
export default function App() {
const [src, selectFile] = useState(null);
const onImageChange = (event) => {
selectFile(URL.createObjectURL(event.target.files[0]));
};
const [image, setImage] = useState(null);
const [crop, setCrop] = useState({ aspect: 16 / 9 });
const [result, setResult] = useState(null);
function getCroppedImg(){
const canvas = document.createElement('canvas');
const scaleX = image.naturalWidth / image.width;
const scaleY = image.naturalHeight / image.height;
canvas.width = crop.width;
canvas.height = crop.height;
const ctx = canvas.getContext('2d');
ctx.drawImage
(
image,
crop.x * scaleX,
crop.y * scaleY,
crop.width * scaleX,
crop.height * scaleY,
0,
0,
crop.width,
crop.height,
);
const base64Image = canvas.toDataURL('image/jpeg');
setResult(base64Image)
}
return (
<div className="container">
<div className='row'>
<div className='col-6'>
<input type="file" accept ='image/*' onChange={onImageChange}/>
</div>
{src && <div className='col-6'>
<ReactCrop src={src} onImageLoaded={setImage} crop={crop} onChange={setCrop} />
<button className='btn btn-danger' onClick={getCroppedImg} > Crop Image </button>
</div>}
{result && <div className='col-6'> <img src={result} alt='Cropped Image' className='img-fluid' />
</div>}
</div>
</div>
);
}
</code></pre>
<p>You can use this sandbox link to immediately test and debug the code and see the error,
<a href="https://codesandbox.io/s/stoic-hooks-l5gfrz" rel="nofollow noreferrer">code testing in sandbox</a></p>
<p>This full code is not mainly mine, I have been following this tutorial on youtube as im trying to get it working to learn and use it on my main project, But i cannot get it working as in there this error, which is not actually in the tutorial as im not even missing any line of code so i cannot understand why this error happening, appreicated to make me understand why it happened.
this is the yt link: <a href="https://www.youtube.com/watch?v=KbPRpBdBN6w&t=351s" rel="nofollow noreferrer">yt tutorial code</a></p>
<p>Also to add, When i try to browse the image in the current code it doesn't work so I actually tried to fix it by adding this line</p>
<pre><code><img src={src} />
</code></pre>
<p>under the it actually started to work for showing the image, but the cropping functionality is not working.</p>

<p>The code here only shows how many words they are, how do i ignore the words that are the same?
For example, "A long long time ago, I
can still remember", would return 8 instead of 9.</p>
<p>I want it to be a method which takes one parameter s of
type String and returns an int value. And im only allowed to use the bacics, so no hash keys and advance stuff.</p>
<pre><code> public static int mostCommonLetter(String s){
int wordCount = 0;
boolean word = false;
int endOfLine = s.length() - 1;
for (int i = 0; i < s.length(); i++) {
if (Character.isLetter(s.charAt(i)) && i != endOfLine) {
word = true;
} else if (!Character.isLetter(s.charAt(i)) && word) {
wordCount++;
word = false;
} else if (Character.isLetter(s.charAt(i)) && i == endOfLine) {
wordCount++;
}
}
return wordCount;
}
}
</code></pre>
<p>How do i ignore the words that are the same?</p>

<p>So, I'm supposed to write a function <code>normpdf(x , avg, std)</code> that returns the Gaussian probability density function of <code>x</code> for a normal distribution with mean <code>avg</code> and standard deviation <code>std</code>, with <code>avg = 0</code> and <code>std = 1</code>.</p>
<p>This is what I got so far, but when I click run, I get this message:</p>
<pre class="lang-py prettyprint-override"><code>Input In [95]
return pdf
^
SyntaxError: invalid syntax
</code></pre>
<p>I'm confused on what I did wrong on that part.</p>
<pre class="lang-py prettyprint-override"><code>import numpy as np
import math
def normpdf(x, avg=0, std=1) :
# normal distribution eq
exponent = math.exp(-0.5 * ((x - avg) / std) ** 2)
pdf = (1 / (std * math.sqrt(2 * math.pi)) * exponent)
return pdf
# set x values
x = np.linspace(1, 50)
normpdf(x, avg, std)
</code></pre>
<p>I added the parenthesis here and <code>math.sqrt</code>:</p>
<pre class="lang-py prettyprint-override"><code>pdf = (1 / (std * math.sqrt(2 * math.pi)) * exponent)

<p>I have a input object</p>
<pre><code> @Getter
class Txn {
private String hash;
private String withdrawId;
private String depositId;
private Integer amount;
private String date;
}
</code></pre>
<p>and the output object is</p>
<pre><code> @Builder
@Getter
class UserTxn {
private String hash;
private String walletId;
private String txnType;
private Integer amount;
}
</code></pre>
<p>In the <strong>Txn</strong> object transfers the <strong>amount</strong> from the <strong>withdrawId -> depositId</strong>.</p>
<p>what I am doing is I am <strong>adding</strong> all the <strong>transactions</strong> (Txn objects) in a single amount <strong>grouped by hash</strong>.</p>
<p>but for that I have to make <strong>two streams for groupingby</strong> withdrawId and second or for depositId and then the <strong>third stream for merging</strong> them</p>
<p>grouping by withdrawId</p>
<pre><code>var withdrawStream = txnList.stream().collect(Collectors.groupingBy(Txn::getHash, LinkedHashMap::new,
Collectors.groupingBy(Txn::getWithdrawId, LinkedHashMap::new, Collectors.toList())))
.entrySet().stream().flatMap(hashEntrySet -> hashEntrySet.getValue().entrySet().stream()
.map(withdrawEntrySet ->
UserTxn.builder()
.hash(hashEntrySet.getKey())
.walletId(withdrawEntrySet.getKey())
.txnType("WITHDRAW")
.amount(withdrawEntrySet.getValue().stream().map(Txn::getAmount).reduce(0, Integer::sum))
.build()
));
</code></pre>
<p>grouping by depositId</p>
<pre><code>var depositStream = txnList.stream().collect(Collectors.groupingBy(Txn::getHash, LinkedHashMap::new,
Collectors.groupingBy(Txn::getDepositId, LinkedHashMap::new, Collectors.toList())))
.entrySet().stream().flatMap(hashEntrySet -> hashEntrySet.getValue().entrySet().stream()
.map(withdrawEntrySet ->
UserTxn.builder()
.hash(hashEntrySet.getKey())
.walletId(withdrawEntrySet.getKey())
.txnType("DEPOSIT")
.amount(withdrawEntrySet.getValue().stream().map(Txn::getAmount).reduce(0, Integer::sum))
.build()
));
</code></pre>
<p>then merging them again, using deposites - withdraws</p>
<pre><code>var res = Stream.concat(withdrawStream, depositStream).collect(Collectors.groupingBy(UserTxn::getHash, LinkedHashMap::new,
Collectors.groupingBy(UserTxn::getWalletId, LinkedHashMap::new, Collectors.toList())))
.entrySet().stream().flatMap(hashEntrySet -> hashEntrySet.getValue().entrySet().stream()
.map(withdrawEntrySet -> {
var depositAmount = withdrawEntrySet.getValue().stream().filter(userTxn -> userTxn.txnType.equals("DEPOSIT")).map(UserTxn::getAmount).reduce(0, Integer::sum);
var withdrawAmount = withdrawEntrySet.getValue().stream().filter(userTxn -> userTxn.txnType.equals("WITHDRAW")).map(UserTxn::getAmount).reduce(0, Integer::sum);
var totalAmount = depositAmount-withdrawAmount;
return UserTxn.builder()
.hash(hashEntrySet.getKey())
.walletId(withdrawEntrySet.getKey())
.txnType(totalAmount > 0 ? "DEPOSIT": "WITHDRAW")
.amount(totalAmount)
.build();
}
));
</code></pre>
<p>My question is, How can I do this in one stream.
Like by somehow groupingBy withdrawId and depositId is one grouping.</p>
<p>something like</p>
<pre><code>res = txnList.stream()
.collect(Collectors.groupingBy(Txn::getHash,
LinkedHashMap::new,
Collectors.groupingBy(Txn::getWithdrawId && Txn::getDepositId,
LinkedHashMap::new, Collectors.toList())))
.entrySet().stream().flatMap(hashEntrySet -> hashEntrySet.getValue().entrySet().stream()
.map(walletEntrySet ->
{
var totalAmount = walletEntrySet.getValue().stream().map(
txn -> Objects.equals(txn.getDepositId(), walletEntrySet.getKey())
? txn.getAmount() : (-txn.getAmount())).reduce(0, Integer::sum);
return UserTxn.builder()
.hash(hashEntrySet.getKey())
.walletId(walletEntrySet.getKey())
.txnType("WITHDRAW")
.amount(totalAmount)
.build();
}
));
</code></pre>

</code></pre>
<p>But to my mild surprise the numbers don't change. Maybe because the <code>A value is trying to be set on a copy of a slice from a DataFrame</code> warning is triggered in the same run. I've also tried with <code>df.mask()</code> and <code>df.where()</code>. But to no avail. I'm clearly failing at something very basic here, but I'd really like to know how to do this properly. There are similarly sounding questions such as <a href="https://stackoverflow.com/questions/28017807/performing-calculations-on-subset-of-data-frame-subset-in-python">Performing calculations on subset of data frame subset in Python</a>, but the suggested solutions here are pointing towards <code>df.groupby()</code>, and I don't think this necessarily is the right approach here.</p>
<p>Thank you for any suggestions!</p>
<p>Here's a fully reproducible dataset:</p>
<pre><code>import pandas as pd
df = pd.DataFrame({
'famid': [1, 1, 1, 2, 2, 2, 3, 3, 3],
'birth': [1, 2, 3, 1, 2, 3, 1, 2, 3],
'ht_one': [2.8, 2.9, 2.2, 2, 1.8, 1.9, 2.2, 2.3, 2.1],
'ht_two': [3.4, 3.8, 2.9, 3.2, 2.8, 2.4, 3.3, 3.4, 2.9]
})
df = pd.wide_to_long(df, stubnames='ht', i=['famid', 'birth'], j='age',
sep='_', suffix=r'\w+')
df.reset_index(inplace = True)
</code></pre>

<p>I would like to know how to add code in my action listener that would make the row I select or press on with my mouse change from the color red to the color white. I have tried getRowSelected() and tried to use the index but that ultimately only changes the row color when it is selected and it goes back to red. I have also attempted to user Renderer which is a newer concept to me but didn't know how to implement it the right way. Any help or guidance would be appreciated.</p>
<p>Tried getRowSelected() but the row color change was only temporary and went back to red once it was unselected. Tried Renderer but didn't know how to fully implement it as it is a new concept to me.</p>

<p>I mapped the countries in select. When I reset the select the placeholder is still the country name, but the value is reset to undefined.</p>
<pre><code>const countries = [
{ label: 'France', value: 'FR' },
{ label: 'Germany', value: 'DE' },
];
</code></pre>
<pre><code>const defaultValues = {
country: undefined,
};
</code></pre>
<pre><code>const Select: FC<Props> = ({
options,
onSelect,
placeholder = 'Select option',
...props
}) => {
const handleSelect = useCallback(
(ev) => {
const { value } = ev.target;
const select = value ? options.find((opt) => opt.value === value) : null;
onSelect(select);
},
[options]
);
return (
<ChakraSelect
onChange={handleSelect}
placeholder={placeholder}
{...props}
>
{options?.map((opt) => (
<option key={opt.label} value={opt.value}>
{opt.label}
</option>
))}
</ChakraSelect>
);
};
export default Select;
</code></pre>
<pre><code><FormControl isInvalid={errors.country}>
<Controller

</code></pre>
<p>Reset using react-hook-form:</p>
<pre><code>reset({...defaultValues});

<p>Here is the result after reset, value: undefined, but the placeholder is still the country name:

<p>I've been trying to get shell from this function but nothing seems to work<br>
so what's happening here is that I have a variable of size 32 bytes and I'm trying to copy 600bytes to it<br>
what I don't understand is, where my shell code will be executed is it inside the 32bytes or in the 600 - 32 bytes.<br>
I can't give the whole working code as this is just a disassembly code from ghidra.</p>
<p>Any help what should I do?<br> Thanks in advance.</p>
<pre class="lang-c prettyprint-override"><code>void foo(void *param)
{
undefined varialbe [32];
memcpy(variable, param, 600);
return;
}
</code></pre>
<p>this is the shellcode I tried</p>
<pre class="lang-bash prettyprint-override"><code>\x31\xc0\x50\x68\x2f\x63\x61\x74\x68\x2f\x62\x69\x6e\x89\xe3\x50\x68\x2e\x74\x78\x74\x68\x66\x6c\x61\x67\x89\xe1\x50\x51\x53\x89\xe1\x31\xc0\x83\xc0\x0b\xcd\x80
</code></pre>
<p>I was expecting that I will get a shell on the system if I just input the above shell code. but all I get for not is segfaults.</p>
<p>I'm new to binary exploitations. so sorry if this is a stupid question and sorry for my english.</p>

<p>I have been trying to make a "hidden text" website of sorts.</p>
<p>I have managed to code a circular <code>div</code> that follows my mouse cursor and inverts every text underneath it using <code>background-filter</code> in CSS and Javascript:</p>
<pre><code>let circle = document.getElementById('circle');
const onMouseMove = (e) => {
circle.style.left = e.pageX + 'px';
circle.style.top = e.pageY + 'px';
}
document.addEventListener('mousemove', onMouseMove);
</code></pre>
<p>The CSS for the #circle element is:</p>
<pre><code>#circle {
position: absolute;
transform: translate(-50%,-50%);
height: 80px;
width: 80px;
border-radius: 50%;
box-shadow: 0px 0px 40px 10px white;
pointer-events: none;
backdrop-filter: invert(100%);
z-index: 100;
}
</code></pre>
<p>I have tried setting the text opacity to 5% and then setting <code>backdrop-filter: opacity(100%)</code> but that didn't work, unfortunately. How should I go about achieving this? I am open to any and all libraries and willing to follow any tutorial. Accessibility is not an issue at the moment as this is just an experiment for myself.</p>

<p>I'd like to create a query scope for my model called <code>Ticket</code>. This <code>Ticket</code> <strong>hasMany</strong> replies (Model: <code>Reply</code>). And each reply can have a status (Enum <code>Status</code>).</p>
<p>Now I'd like to create a scope on the <code>Ticket</code> model, which should filter all tickets having more than 2 replies in the status <code>UNREAD</code>.</p>
<p>This is my first attempt:</p>
<pre class="lang-php prettyprint-override"><code>public function scopeEscalatedTickets(Builder $query): Builder
{
return $query->has('replies', function (Builder $q){
$q->whereNot('status', Status::READ);
});
}
</code></pre>
<p>But now I'm stuck: How can I create the count-condition so this takes into account that I just want the tickets having more than 2 replies which do not have the <code>Status::READ</code>?</p>
<p>My second thought about using something like</p>
<pre class="lang-php prettyprint-override"><code>->withCount('replies')->having('replies_count', '>', 2)
</code></pre>
<p>does not work too, and inspecting the SQL-query I at least found out that <code>withCount</code> really just counts all the related items and ignores other conditions.</p>
<p>Thanks for your help :-)</p>

<p>I'm consuming some k8s objects with typescript and my json looks like this:</p>
<pre><code>{
"startTime": "2022-12-01T19:15:58Z",
"taskRuns": {
"task1": {
"pipelineTaskName": "task1Ref",
"status": {
"completionTime": "2022-12-01T19:17:27Z",
"conditions": [
{
"lastTransitionTime": "2022-12-01T19:17:27Z",
"message": "",
"reason": "TaskRunImagePullFailed",
"status": "False",
"type": "Succeeded"
}
]}},
"task2":{same fields as task1},
"task3": {same}
}}
</code></pre>
<p>I also have an array with the TaskRun names which looks like the following:</p>
<pre><code>["task1","task2",....]
</code></pre>
<p>The relevant interface for the object above looks like:</p>
<pre><code>export interface PipelineRunStatus {
startTime: string;
taskRuns: Truns;
}
export interface Truns {
[key: string]: TaskRun;
}
export interface TaskRUn {<fields from above>}
</code></pre>
<p>I'm trying to match the array elements to the variable task keys in a taskrun and extract information with the code below:</p>
<pre><code> type taskRunKey = keyof typeof currentRun.Status.taskRuns
//taskRuns is my string array
taskRuns.map((taskRunName: string) => {
console.log(taskRunName)
if (currentRun?.Status?.taskRuns?.hasOwnProperty(taskRunName as taskRunKey))
console.log(currentRun.Status?.taskRuns[taskRunName as status?.conditions[0])
else {
console.log(currentRun?.Status?.taskRuns)
console.log(currentRun?.Status)
}
</code></pre>
<p>but this prints</p>
<pre><code>task1
undefined
Object { TaskRuns: {… task1:{..the object above...}}}
task2
undefined
Object { TaskRuns: {… pretty much the object above...}}
</code></pre>
<p>etc</p>
<p>In short: the code above always ends up in the "else" branch of the statement despite the fact that there is an object property with the correct name that matches.
Can someone please explain what am I missing?</p>

<p>I am trying to get all users that have a certain <strong>listId</strong> in their contactLists object. My firebase <strong>realtime</strong> database structure is as follows:</p>
<pre><code>user:
john:
contactLists:
-NIOsvb: true,
</code></pre>
<p>I have other users in the DB and I want to get all that have -NIOsvb in their contactLists object.
This is the approach I tried (listId is passed as a parameter):</p>
<pre><code>const snapshot = await get(query(ref(db, "users"), orderByChild("contactLists"), equalTo(listId)))
</code></pre>
<p>I expected to get all the user objects that have this id in their contactLists. However, the value of snapshot is null. Any suggestions would be appreciated, as I don't have a lot of experience with Firebase functions.</p>

In cell B1 I have how many actually rows with data I have.
i.e The sheet is called Raw Data and if B1=100 I need range B2:E102 copied into sheet Master
The value in B1 is dynamic, depending on data in another sheet).
Could someone please help me with this?

<p>I have an input array which contains various domains:</p>
<pre class="lang-js prettyprint-override"><code>var sites = ["site2.com", "site2.com", "site3.com"];
</code></pre>
<p>I need to check, whether certain string <code>domainName</code> matches one of these sites. I used
<code>indexOf</code> which worked fine, however problem occured when certain <code>domainName</code> was shown with subpage, e.g.
<code>subpage.site1.com</code>.
I tried to use <code>some</code> method with RegExp testing instead:</p>
<pre class="lang-js prettyprint-override"><code>if(sites.some(function(rx) { return rx.test(domainName); })
</code></pre>
<p>however the first problem was that I needed to change <code>""</code> for every element to <code>"\\"</code> to make it work with RegExp:</p>
<pre class="lang-js prettyprint-override"><code>var sites = [/site1.com/, /site2.com/, /site3.com/];
</code></pre>
<p>while I want to keep array with quotation marks for end-user.</p>
<p>Second problem was that it returns <code>true</code> for in cases where compared <code>domainName</code> is not in array, but partially its name contains is part of element in array, for example <code>anothersite1.com</code> with <code>site1.com</code>. It's rare case but happens.</p>
<p>I can modify my input array with RegExp will start and end with <code>^$</code> escape characters, but it will complicate it even more, especially that I will need to also add <code>([a-z0-9]+[.])</code> to match subpages.</p>
<p>I tried to use <code>replace</code> to change <code>"foo"</code> to <code>\foo\</code>, but I was unable since quation marks defines array elements. Also I tried to use <code>replace</code> with <code>concat</code> to merge string with escape characters to achieve element looking like RegExp formula from <code>site1.com</code> to <code>^([a-z0-9]+[.])*site1\.com$</code> but got issues with escaping characters.</p>
<p>Is there a simpler way to achieve this goal?</p>

<p>If I understand correctly, value initialization <code>T obj {};</code> uses the user-define constructor while default initialization <code>T obj;</code> either uses the user-define constructor or leaves <code>obj</code> uninitialized (i.e. undefined).</p>
<p>Since having uninitialized values is in general bad style, should we always prefer value initialization over default initialization? Is there any scenario where default initialization is actually better than value initialization?</p>

<p>If my understanding is correct, the following declarations should both call the copy constructor of <code>T</code> which takes type of <code>x</code> as a parameter.</p>
<pre><code>T t = x;
T t(x);
</code></pre>
<p>But when I do the same for <code>std::unique_ptr<int></code> I get an error with the first declaration, while the second compiles and does what is expected.</p>
<pre><code>std::unique_ptr<int> x = new int();
std::unique_ptr<int> x (new int());
</code></pre>
<p>Is there a difference in the two syntax for calling the copy constructor?</p>

<p>Say I have a list of files with mixed suffixes, e.g. .cpp and .c, and I want to make a list where each .cpp and each .c extension is changed to .o. I realize I could sequentially process my list multiple times, one for each extension of interest. But is there a way to use a variable substitution to do it in one step?</p>

<p>I am using the <a href="https://platform.uno/" rel="nofollow noreferrer">Uno Platform</a> and trying to create a <a href="https://gallery.platform.uno/" rel="nofollow noreferrer">Material Card</a> through C#. I have been able to find a number of examples of a Card created in XAML but nothing in C#.</p>
<p>My current code is below to create a Card and add it to a Grid. I know I need to do something with adding a HeaderContentTemplate and SubHeaderContentTemplate but I am sure exactly what needs to be done.</p>
<pre><code>Card myCard = new Card();
myCard.HeaderContent = "test";
myCard.SubHeaderContent = "test";
Grid.SetRow(myCard, k);
Grid.SetColumn(myCard, l);
myGrid.Children.Add(myCard);
</code></pre>
<p>Any help would be greatly appreciated. Thank you.</p>

<p>I have a component that calls a method which in the background computes a heavy calculation with a map function (not fetching anything), and I'm looking to insert a callback function in there to update the DOM with the loading percentage of the computation with every iteration of the map function.</p>
<p>Basically, I'm trying to update the DOM with the loadingPercentage variable in the following code. Console.log statement outputs the correct percentages.</p>
<p>`</p>
<pre><code> useEffect(() => {
const frames: AnimationFrame[] = getAnimationFrames(
(loadingPercentage: number) => {
console.log(loadingPercentage);
// Here's the part I'm trying to insert something to update the DOM
}
);
setFrames(frames.map((frame) => frame.analysis));
setBoards(frames.map((frame) => frame.board));
}, []);
</code></pre>
<p>`</p>
<p>I'm trying to get the percentage on the DOM as follows:</p>
<pre><code><div>{loadingPercentage}</div>
//Not updating at all...
</code></pre>
<p>In case it could be useful, the heavy computation I mentioned in this case is <strong>getAnimationFrames()</strong> which is located in a non-react typescript file as such:</p>
<pre><code>export const getAnimationFrames = (
loading?: Function,
pgn: string = defaultPgn
) => {
const history = getHistoryFromPgn(pgn);
const totalMoves = history.length;
let loadingPercentage = 0;
let moveNo = 0;
const animationFrames: AnimationFrame[] = history.map((move) => {
const animationFrame = getAnimationFrame(move);
moveNo++;
loadingPercentage = (moveNo * 100) / totalMoves;
if (loading) {
**loading(loadingPercentage);**
}
return animationFrame;
});
return animationFrames;
};
</code></pre>
<p>What I tried:</p>
<ol>
<li><p>Making a state variable like const [loadingPercentage, setLoadingPercentage] = useState(0) and add it as a dependency to the useEffect hook but the getAnimationFrames function must be called only once so that didn't make a lot of sense.</p>
</li>
<li><p>Removing the getAnimationFrames function, and instead of using a loop I tried to get useEffect to behave like a loop by adding getAnimationFrame in the useEffect function to push the frames to an array with each component load, with the loadingPercentage as a dependency of useEffect. This seemed like it almost worked but eventually it started giving too many renders error.</p>
</li>
<li><p>Tried const loadingPercentage = useRef(0);, and updated loadingPercentage.current with loadingPercentage value at every iteration. This did not update the DOM as expected.</p>
</li>
<li><p>Tried abandoning React all together and did document.getElementById('loadingDiv').innerText = loadingPercentage. Seems like this is very easy to do with Vanilla JS, but cannot get it to work in React.</p>
</li>
</ol>
<p>Let me know if you have any ideas.</p>
<p>Thank you!</p>

<p>Can someone help me to set stop loss = 100 pips to this strategy? I have no idea how to do it</p>
<pre><code>//@version=5
strategy("MovingAvg2Line Cross", overlay=true)
fastLength = input(9)
slowLength = input(18)
price = close
mafast = ta.sma(price, fastLength)
maslow = ta.sma(price, slowLength)
if (ta.crossover(mafast, maslow))
strategy.entry("MA2CrossLE", strategy.long, comment="MA2CrossLE")
if (ta.crossunder(mafast, maslow))
strategy.entry("MA2CrossSE", strategy.short, comment="MA2CrossSE")
//plot(strategy.equity, title="equity", color=color.red, linewidth=2, style=plot.style_areabr)
</code></pre>
<p>If someone can write for me code of stop loss i would be grateful</p>

<p>Suppose I have <code>ABC</code> in cell <code>A1</code> and <code>XaA</code> in cell B1. Taking into account upper and lower case I would like to recognize that <code>A</code> is indeed in common. How can I do this using Excel or Google Sheets function?</p>
<p>Thank you</p>
<p>I used <code>=INDEX(FLATTEN(FILTER(FLATTEN(FILTER(REGEXEXTRACT(TO_TEXT(E1), REPT("(.)", LEN(E1))),REGEXEXTRACT(TO_TEXT(E1), REPT("(.)", LEN(E1)))<>"")), FLATTEN(FILTER(REGEXEXTRACT(TO_TEXT(E1), REPT("(.)", LEN(E1))),REGEXEXTRACT(TO_TEXT(E1), REPT("(.)", LEN(E1)))<>""))<>"")&""&TRANSPOSE(FILTER(FLATTEN(FILTER(REGEXEXTRACT(TO_TEXT(E2), REPT("(.)", LEN(E2))),REGEXEXTRACT(TO_TEXT(E2), REPT("(.)", LEN(E2)))<>"")), FLATTEN(FILTER(REGEXEXTRACT(TO_TEXT(E2), REPT("(.)", LEN(E2))),REGEXEXTRACT(TO_TEXT(E2), REPT("(.)", LEN(E2)))<>""))<>""))))</code> formula but clearly I am not moving in the right direction.</p>

<p>I'm new using the boost::multiprecision library and tried to use it combination with boost::math::interpolators::cardinal_cubic_b_spline however I can't compile the program.</p>
<p>The example code is</p>
<pre><code>#include <boost/math/interpolators/cardinal_cubic_b_spline.hpp>
#include <iostream>
#include <boost/multiprecision/gmp.hpp>
using boost::multiprecision::mpf_float_50;
int main() {
std::vector<mpf_float_50> v(10);
mpf_float_50 step(0.01);
for (size_t i = 0; i < v.size(); ++i) {
v.at(i) = sin(i*step);
}
mpf_float_50 leftPoint(0.0);
boost::math::interpolators::cardinal_cubic_b_spline<mpf_float_50> spline(v.begin(), v.end(), leftPoint, step);
mpf_float_50 x(3.1);
mpf_float_50 tmpVal = spline(x);
std::cout << tmpVal << std::endl;
return 0;
}
</code></pre>
<p>When change the type of variables to boost::multiprecision::cpp_bin_float_50 the program is working. Also, boost::multiprecision::mpf_float_50 is working in all other examples I have tried.</p>
<p>The error I get is:</p>
<pre><code>/home/..../main.cpp:19:31: required from here
/usr/include/boost/math/interpolators/detail/cardinal_cubic_b_spline_detail.hpp:50:10: error: conversion from ‘expression<boost::multiprecision::detail::function,boost::multiprecision::detail::abs_funct<boost::multiprecision::backends::gmp_float<50> >,boost::multiprecision::detail::expression<boost::multiprecision::detail::subtract_immediates, boost::multiprecision::number<boost::multiprecision::backends::gmp_float<50> >, long unsigned int, void, void>,[...],[...]>’ to non-scalar type ‘expression<boost::multiprecision::detail::subtract_immediates,boost::multiprecision::number<boost::multiprecision::backends::gmp_float<50> >,long unsigned int,[...],[...]>’ requested
</code></pre>
<p>The same error appeared for cpp_dec_float_50, mpfr_float_50 etc. I'm not sure what I'm doing wrong.</p>

<p>I am looking for a harsher version of <code>[[nodiscard]]</code> that throws an fatal error instead of a warning when a return value is ignored. So for example:</p>
<pre><code>[[harshnodiscard]] int getSize() { return 0; }
</code></pre>
<p>Any code that ignores the return value of <code>getSize</code> should not compile.</p>
<p>Is there any functionality for this?</p>

<p>I tried reinstalling and resetting my settings, no luck.</p>

<p>In Rust Polars(might apply to python pandas as well) assigning values in a new column with a complex logic involving values of other columns can be achieved in two ways. The <a href="https://stackoverflow.com/questions/70968749/pandas-replace-equivalent-in-python-polars">default</a> way is using a nested <a href="https://docs.rs/polars/latest/polars/prelude/struct.When.html" rel="nofollow noreferrer">WhenThen</a> expression. Another way to achieve same thing is with LeftJoin. Naturally I would expect When Then to be much faster than Join, but it is not the case. In this example, When Then is <strong>6 times slower</strong> than Join. Is that actually expected? Am I using When Then wrong?</p>
<p>In this example the goal is to assign weights/multipliers column based on three other columns: <em>country</em>, <em>city</em> and <em>bucket</em>.</p>
<pre class="lang-rust prettyprint-override"><code>use std::collections::HashMap;

<p>The result is surprising to me: <code>Left Join took: 561.26ms</code> vs <code>Chained When Then: 3.22s</code></p>
<p>Thoughts?</p>
<h2>UPDATE</h2>
<p>This does not make much difference. Nested WhenThen is still over 3s</p>
<pre class="lang-rust prettyprint-override"><code>// Test with nested When Then
let now = Instant::now();
let r1 = frame.clone().with_column(
when(col("country").eq(lit("UK")).and(col("city").eq(lit("London"))))
.then(rf_rw_map(col("bucket"),weight_map,NULL.lit()))
.otherwise(NULL.lit())
)
.collect().unwrap();
let elapsed = now.elapsed();
println!("Chained When Then: {:.2?}", elapsed);

<p>am writing this algorithm that takes strings from a text file and appends them to an array. if the strings are in continuous line ex.</p>
<pre><code>ABCD
EFG
HIJK
LMNOP
</code></pre>
<p>then they would be appended into the same array until it reaches a blank line at which point it stops and starts appending the next number of continuous arrays to a different array.</p>
<p>In my head a for loop is the way to go as i have the number of lines but i am just not sure how to check if a line has ANY TYPE of text or not (Not looking for any substrings just checking if the line itself contains anything).</p>

<p>I'm trying to create a search error for my ecommerce website. When a user inputs a search that is not in the database, it should return the search error page. Though it seems my else clause isn't working.</p>
<p>I tried putting the else clause in the search.html page, but it keeps giving me errors and it seems when I try to fix the errors, nothing really happens, it stays the same. I expect the search_error.html page to appear when the user inputs a product name that is not in the database. Though I keep getting for example, when I type "hello," the page appears with "Search results for hello." But it should result the search_error.html page. I also tried currently a else clause in my views.py, but it shows the same thing. I think my else clause isn't working and I don't know why.</p>
<p>My views.py:</p>
<pre><code>def search(request):
if 'searched' in request.GET:
searched = request.GET['searched']
products = Product.objects.filter(title__icontains=searched)
return render(request, 'epharmacyweb/search.html', {'searched': searched, 'products': products})
else:
return render(request, 'epharmacyweb/search_error.html')
def search_error(request):
return render(request, 'epharmacyweb/search_error.html')
</code></pre>
<p>My urls.py under URLPatterns:</p>
<pre><code>path('search/', views.search, name='search'),
path('search_error/', views.search_error, name='search_error'),
</code></pre>
<p>My search.html page:</p>
<pre><code>{% if searched %}
<div class="pb-3 h3">Search Results for {{ searched }}</div>
<div class="row row-cols-1 row-cols-sm-2 row-cols-md-5 g-3">
{% for product in products %}
<div class="col">
<div class="card shadow-sm">
<img class="img-fluid" alt="Responsive image" src="{{ product.image.url }}">
<div class="card-body">
<p class="card-text">
<a class="text-dark text-decoration-none" href="{{ product.get_absolute_url }}">{{ product.title }}</a>
</p>
<div class="d-flex justify-content-between align-items-center">
<small class="text-muted"></small>
</div>
</div>
</div>
</div>
{% endfor %}
</div>
<br></br>
{% else %}
<h1>You haven't searched anything yet...</h1>
{% endif %}
</code></pre>
