74,412,333 | <p>I have a canvas and when i click on it, it draws a line.</p>
<p>Line is a function:</p>
<pre><code>const line = (x1, y1, x2, y2) => {
return (
<line id="lineD" x1={x1} y1={y1} x2={x2} y2={y2} style={{ stroke: "black", strokeWidth: 3, strokeLinecap: "round" }}></line>
)
}
</code></pre>
<p>It works fine, except when I scale the canvas. When I do so, I change a <code>scale</code> state.</p>
<p>So I want line attributes to be like this: <code>x1={x1 * scale}</code>, but it only sets it once.</p>
<p>This is how I add lines, (content is another state):</p>
<pre><code>content.push(line(100, 100, 200, 200))
</code></pre>
<p>(these are just random numbers)<br />
And svg is: <code><svg>{content}</svg></code></p>

74,412,342 | <p>For example, I have table</p>
<pre><code>id;name
1;John
2;Mary
3;Cat
4;Cheng
</code></pre>
<p>I want selection to stop right after 3;Cat and still have as much rows in it as exist berore 3;Cat
I think this could be described with such a query</p>
<p><code>SELECT * FROM table WHERE condition ORDER BY id LIMIT name = 'Cat'</code></p>
<p>but of course there is no such a construction <strong>LIMIT name='Cat'</strong> in SQL.
Maybe something else fits?</p>
<p>Currently Im using extensive select, but it requires enormous 1200 rows to be sure that it has at least one record expected.</p>

74,412,345 | <p>I'm trying to create a function in python that from a list of strings will return me a dict where the key(index) shows the most repetitive character for each index between all the strings. for example a list1 = ['one', 'two', 'twin', 'who'] should return index 0=t index 1=w index 2=o index 3=n in fact the most frequent character at the index 1 between all the string is 'w'.
I found a solution but if I have lists with thousands of strings inside it will require too much time to perform. I would like to know if you can give me some help to decrease the time of execution.</p>
<p>Here is what I tried to do but seems too slow to perform with lists of thousands strings inside</p>
<pre><code>list1 = ['one', 'two', 'twin', 'who']
width = len(max(list1, key=len))
chars = {}
for i, item in enumerate(zip(*[s.ljust(width) for s in list1])):
set1 = set(item)
if ' ' in set1:
set1.remove(' ')
chars[i] = max(set1, key=item.count)
print(chars)
</code></pre>

74,412,363 | <p>I have a list(string): []</p>
<p>I need to multiply every two elements and than sum up the results</p>
<p>So for the list:[0,1,2,3,4]</p>
<p>I need to get the result: 105.</p>
<p>(0+1)×(1+2)×(2+3)×(3+4)=105</p>
<p>How do I do that?</p>
<p>I tried to write this code:</p>
<pre class="lang-py prettyprint-override"><code>Lst3= [0,1,2,3,4]
multiply=0
sum=0
count=1
for i in lst3:
multiply= i*lst3[i+1]
sum= sum+multiply
count=count+1
print (sum)

74,412,364 | <p>I have made this login form from my basic HTML CSS and JavaScript knowledge. There is a Remember me button in this login form I have created and now I have to give it a functionality.
I want to click OK button and then it should:
Create a cookie if Remember Me is set and save Student Id and Name.
I am using Visual Studio Code.
Here is my HTML + JavaScript Code:</p>

</html>
</code></pre>
<p><strong>CSS Code:-</strong></p>
<pre><code>form{

74,412,421 | <p>Consider microservices architecture, where you need to expose functionality to manage simple configuration shared with different microservices. Configuration is not changing often, but still, I would like to see changes whenever I ask for any value.
Using REST microservice seems easy, but it is adding latency.
Alternative could be RPC over messaging (i.e. RabbitMQ), but interface becomes more complicated.</p>
<p>What communication are you using for internal, simple services and what are pros and cons?
Any examples?</p>
<p>I tried with REST API, but it means a lot of "slow" requests, which add a latency to overall requests.</p>

74,412,498 | <p>How can you write a function f that takes another function g as an argument, but where function g has arguments that change dynamically depending on what happens in function f?</p>
<p>A pseudocode example would be:</p>
<pre><code>def function(another_function(parameters)): # another function passed as an argument, with parameters
for i in range(10):
print(another_function(i))
</code></pre>
<p>So when i iterates, function f is called with a new argument i every time. How could that be implemented?</p>
<p>I found one can use *args as a parameter, but did not see how it could be implemented.</p>
<p>Cheers</p>

<input type="submit" onClick={submit} id='mdg' value="GO!" disabled></input>
</div>
</div>
</form>

<p>After this code the page refreshes and I also use e.preventDefault function to stop it because I same issue before but it doesn't worked</p>
<p>function with preventDefault:</p>
<pre><code>const submit = (event) => {
event.preventDefault();
fetch('http://localhost:3001/quizInfo',{
method: 'POST',
mode: 'cors',
cache: 'no-cache',

74,412,546 | <p>I'm using a ReorderableListView builder in combination with a Bottom App Bar with a FAB.
I set extendBody because I want the FAB notch to be transparent when scrolling up/down the list. However with a ReorderableListView I cannot scroll down to the last list item because the list item is hidden behind the Bottom App Bar.</p>
<p>Here's a demonstration:</p>
<p><a href="https://i.stack.imgur.com/h5Vxf.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/h5Vxf.png" alt="enter image description here" /></a></p>
<p>This is not the case with a regular ListView as you can see in the code example below and on this picture right here. This would be my intended behaviour because the last list item is fully visible:</p>
<p><a href="https://i.stack.imgur.com/o8V5H.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/o8V5H.png" alt="enter image description here" /></a></p>
<p>Important: It's not a solution to just set extendBody to false because there would be no transparent notch when scrolling. The scrolling behaviour itself is correct for ReorderableListView and ListView and looks like this when scrolling:</p>
<p><a href="https://i.stack.imgur.com/8Wkwc.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8Wkwc.png" alt="enter image description here" /></a></p>
<p>Is there a way to access the last list element with a Reorderable List View similar than with a List View?</p>
<p>Here's a code example with both versions:</p>
<pre><code>import 'package:flutter/material.dart';
void main() {
runApp(SO());
}
class SO extends StatelessWidget {
List<String> myList = ["a", "b", "c", "d", "e", "f", "g", "h"];
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Builder(
builder: (context) => Scaffold(
extendBody: true,
appBar: AppBar(),
body:
// CANNOT scroll up to the last element
ReorderableListView.builder(
itemCount: myList.length,
itemBuilder: (BuildContext context, int index) {
return Container(
key: ValueKey(myList[index]),
height: 150,
color: Colors.green,
child: Center(child: Text('Entry ${myList[index]}')),
);
},
onReorder: (oldIndex, newIndex){
if (newIndex > oldIndex) newIndex --;
final item = myList.removeAt(oldIndex);
myList.insert(newIndex, item);
},
),
/*
// CAN scroll up to the last element
ListView.builder(itemCount: myList.length,
itemBuilder: (BuildContext context, int index) {
return Container(
key: ValueKey(myList[index]),
height: 150,
color: Colors.green,
child: Center(child: Text('Entry ${myList[index]}')),
);
},
),
*/
floatingActionButtonLocation: FloatingActionButtonLocation.centerDocked,
floatingActionButton: FloatingActionButton(
onPressed: () {},
),
bottomNavigationBar: BottomAppBar(
shape: const CircularNotchedRectangle(),
notchMargin: 18,
color: Colors.blue,

74,412,579 | <p>I investigate boguszpawlowski Compose Calendar and I cannot find a way to track state changes of the component, because there are no callback for it.
For example I need to get events only for current month (send a request) and after it I should show them in calendar. When user switch month I should send a request again.
Author in description suggest using state hoisting for it.</p>
<blockquote>
<p>In case you need to react to the state changes, or change the state from the outside of the composable, you need to hoist the state out of the Calendar composable:</p>
</blockquote>
<pre><code> @Composable
fun MainScreen() {
val calendarState = rememberCalendarState()
StaticCalendar(calendarState = calendarState)
// now you can manipulate the state from scope of this composable
calendarState.monthState.currentMonth = MonthYear.of(2020, 5)
}
</code></pre>
<p>I understand how to change current of initial month, but I do not know how to listen event when user swipe calendar or click the button to change month.
How can I do it?</p>

const callbacks = this.onBeforeCloseCallbacks.map((cb) => new Promise(res => res(cb())));
const timeout = new Promise((res) => setTimeout(res, TIMEOUT_DURATION));
await Promise.race([Promise.all(callbacks), timeout]).then((value) => {
// Currently returns Promise.all(callbacks) right away
console.log(value)
});
await this.pluginEngine.close();
}
}
</code></pre>
<p>These are my tests</p>
<pre><code>it('Should still close the plugin when timing out', async () => {
// Arrange
const cleanupMock = jest.fn();
const cb1 = jest.fn().mockReturnValue(async () => new Promise(resolve => setTimeout(() => resolve(console.log('cb1')), 3000)));
const cleanupMock2 = jest.fn();
const cb2 = jest.fn().mockReturnValue(async () => new Promise(resolve => setTimeout(() => resolve(console.log('cb2')), 11000)));
const placementCloseService = new PlacementCloseService(integrationMock, pluginInterface);
// Act
// onBeforeClose is registering callbacks that needs to be run before close
placementCloseService.onBeforeClose(cb1);
placementCloseService.onBeforeClose(cb2);
await placementCloseService.close();
// Assert
expect(cleanupMock).toBeCalled();
expect(cleanupMock2).not.toBeCalled();
expect(pluginInterface.context.close).toBeCalled();
});
</code></pre>
<p>My current solution is returning <code>Promise.all(callbacks)</code> even if it hasn't called expected callbacks to run yet. What I expect to happen is that it passes through my <code>timeout</code> instead since it has a timer of 4000 and the last closeCallback has a timer of 5000.</p>
<p>What am I doing wrong?</p>

74,412,625 | <p>I have algorithm that uses iterators, but there is a problem with transforming values, when we need more than single source value.
All transform iterators just get some one arg and transforms it. (see <a href="https://stackoverflow.com/questions/11424565/how-can-i-write-an-iterator-wrapper-that-combines-groups-of-sequential-values-fr">similar question from the past</a>)
Code example:</p>
<pre><code>template<typename ForwardIt>
double some_algorithm(ForwardIt begin, ForwardIt end) {
double result = 0;
for (auto it = begin; it != end; ++it) {
double t = *it;
/*
do some calculations..
*/
result += t;
}
return result;
}
int main() {
{
std::vector<double> distances{ 1, 2, 3, 4 };
double t = some_algorithm(distances.begin(), distances.end());
std::cout << t << std::endl;
/* works great */
}
{
/* lets now work with vector of points.. */
std::vector<double> points{ 1, 2, 4, 7, 11 };
/* convert to distances.. */
std::vector<double> distances;
distances.resize(points.size() - 1);
for (size_t i = 0; i + 1 < points.size(); ++i)
distances[i] = points[i + 1] - points[i];
/* invoke algorithm */
double t = some_algorithm(distances.begin(), distances.end());
std::cout << t << std::endl;
}
}
</code></pre>
<p>Is there a way (especialy using std) to create such an iterator wrapper to avoid explicitly generating distances value?
It could be fine to perform something like this:</p>
<pre><code>template<typename BaseIterator, typename TransformOperator>
struct GenericTransformIterator {
GenericTransformIterator(BaseIterator it, TransformOperator op) : it(it), op(op) {}
auto operator*() {
return op(it);
}
GenericTransformIterator& operator++() {
++it;
return *this;
}
BaseIterator it;
TransformOperator op;
friend bool operator!=(GenericTransformIterator a, GenericTransformIterator b) {
return a.it != b.it;
}
};
</code></pre>
<p>and use like:</p>
<pre><code>{
/* lets now work with vector of points.. */
std::vector<double> points{ 1, 2, 4, 7, 11 };
/* use generic transform iterator.. */
/* invoke algorithm */
auto distance_op = [](auto it) {
auto next_it = it;
++next_it;
return *next_it - *it;
};
double t = some_algorithm(
generic_transform_iterator(points.begin(), distance_op),
generic_transform_iterator(points.end() -1 , distance_op));
std::cout << t << std::endl;
}
</code></pre>
<p>So general idea is that transform function is not invoked on underlying object, but on iterator (or at least has some index value, then lambda can capture whole container and access via index).</p>
<p>I used to use boost which has lot of various iterator wrapping class.
But since cpp20 and ranges I'm curious if there is a way to use something existing from std:: rather than writing own wrappers.</p>

74,412,630 | <p>I am looking for an elegant way to check if a given index is inside a numpy array (for example for BFS algorithms on a grid).</p>
<p>The following code does what I want:</p>
<pre><code>import numpy as np
def isValid(np_shape: tuple, index: tuple):
if min(index) < 0:
return False
for ind,sh in zip(index,np_shape):
if ind >= sh:
return False
return True
arr = np.zeros((3,5))
print(isValid(arr.shape,(0,0))) # True
print(isValid(arr.shape,(2,4))) # True
print(isValid(arr.shape,(4,4))) # False
</code></pre>
<p>But I'd prefer something build-in or more elegant than writing my own function including python for-loops (yikes)</p>

399 19.9 -0.865213 9.9 0.994372 7093.579
</code></pre>
<p>And a <code>test_df</code> with scatter points:</p>
<pre><code> x y
0 -6.2 0.360801
1 6.4 -3.655422
2 -17.6 -6065.659700

97 -13.3 1.857445
98 -3.8 -0.008831
99 -13.2 1.294064
</code></pre>
<p>I want to find the deviation(distance) between all the scatter points and the 4 functions when the x-value is the same on both data frames.</p>
<p>There are some scatter points with same x-value and different y-value.</p>
<p><strong>Edit:</strong> A quick example:</p>
<p>Starting with column <code>y1</code> from <code>func_df</code>:</p>
<p>1st value is x = -20.0 , y1 = -0.839071.</p>
<p>I want the program to search if there a row in which x = -20.0 in <code>test_df</code> and if so, then find the difference between the y-value of that row and the y-value of <code>func_df</code>, which is -0.839071.</p>
<p>Imagine that in <code>test_df</code> there is a row with x = -20, y = -1. Then what I want is <code>abs(-1 - 0.839071)</code>.
I used <code>abs()</code> because the distance has to be a positive value</p>
<p>This was for the row 0 of column y1. I need it for all rows and also for y2, y3 and y4 of <code>func_df</code>.</p>
<hr />
<p>I tried something like this:</p>
<pre><code>if test_df.x.equals(func.x):
result_df = func.iloc[:, 1:5].apply(lambda cell: cell - test_df.y[cell.index])
</code></pre>
<p>But honestly was a shot in the dark, no idea what I'm doing.</p>

74,412,744 | <p>I've created a new swiftui project in Xcode 14.1 on a MacBook Air M1</p>

'FirebaseFirestoreSwift'<br />
'GoogleMLKit/Translate', '3.2.0'</p>

74,412,790 | <p>When I apply COUNTIF to a range that contains calculations, I get an error message.
To avoid that, can I also narrow the range only to certain columns?</p>
<p>For example, instead of <code>=COUNTIF($A$1:E;F1)</code> something like <code>=COUNTIF($A$1:A AND $C$1:C AND $E$1:E;F1)</code></p>
<p>So that certain columns like B and D in my example are not included in the range?</p>

74,412,804 | <p>I have been struggling on this for a while without prevail. I am trying to run a test script with</p>
<pre><code>import numpy as np
array1 = np.array([1,2,3])
</code></pre>
<p>However, I get the error "No module named 'numpy'". The same goes for Tensorflow.
But trying "pip install numpy" on terminal gives "Requirement already satisfied: numpy in /usr/local/lib/python3.9/site-packages (1.23.4)".</p>
<p>And when I move the script to another directory, in which I already have ran Numpy in, it runs without error. Why does the Numpy module (also Tensorflow) work in that directory, but not in the new one I created?</p>
<p>Tried to uninstall and install Numpy in Terminal</p>

{ "name" => "John", "hobby" => "tennis", "food" => "pizza" },
{ "name" => "Joseph", "hobby" => "tennis", "food" => "burgers" },
{ "name" => "Lauren", "hobby" => "board games", "food" => "salads" }
{ "name" => "Amir", "hobby" => "cycling", "food" => "burgers" },
{ "name" => "Mary", "hobby" => "tennis", "food" => "salads" },
{ "name" => "Karen", "hobby" => "board games", "food" => "pie" },
{ "name" => "Will", "hobby" => "cycling", "food" => "pizza" },
]
</code></pre>
<p>I need to write a program that will take in user input - either "hobby" or "food" and will then puts out a list of people grouped under subheadings for each hobby or food.</p>
<p>e.g. user inputs 'hobby' and a list is puts'ed to the console similar to the below:</p>
<p>tennis
John
Joseph
Mary
board games
Lauren
Karen
cycling
Amir
Will</p>
<p>So far I have got as far as being able to generate a new array that has the hobbies and the names, however they are seperate and I'm not sure if it's the best way of going around getting the category name with a list of people underneath... also there are a few nil values being pulled out too e.g. below:</p>
<pre><code> puts "Enter what category to search"
category = gets.chomp
grouped_data = people.group_by { |x| x[category] }
new_array = []
grouped_data.each { |n| new_array.push n[0] }
grouped_data.flatten.flatten.each { |n| new_array.push n["name"] }
p new_array
</code></pre>
<p>With input "hobby" gives me an array:</p>
<pre><code> ["tennis", "board games", "cycling", nil, "John", "Joseph", "Mary", nil, "Lauren", "Karen", nil, "Amir", "Will"]
</code></pre>
<p>Am I on the right track? Is there another avenue worth exploring?</p>
<p>Thanks! Hope this has been laid out alright as it's first time posting on SA.</p>

74,412,815 | <p>I'm trying to iterate over a list and change its values with a "for in" loop:</p>
<pre><code>example_string = "This is a string."
for char in example_string :
char = 'r'
example_list = list(example_string)
for char in example_list:
char = 'r'
</code></pre>
<p>The string object is not modified by the iteration.</p>
<p>Does the "for in" iteration in Python returns another variable and not the actual list/string element?</p>
<p>I tried doing it with lists. I expected that the items in the list or string would get changed by the assignment.</p>

<p>My application is mainly based on spring boot micro services. Currently it uses OAuth with password grant_type which is deprecated in the latest spring security authorization server release. For receiving JWT token, it stores client id and client secret in React JS frontend which is not secure and not recommended. Users need to register to access certain resources and application maintains login credentials in mysql DB</p>
<p>I am trying to upgrade spring security and want 'account service' to act as authorization server to issue JWT tokens.</p>
<ol>
<li>Am I correct in my understanding that I need to use authorization_code grand type with PKCE?</li>
<li>If I use PKCE then I do not need users to provide passwords while registering, is that correct? Storing only username/email should suffice because users just need to pass client ID and code_challenge to get authorization code?</li>
</ol>

74,413,028 | <p>I am building a web application with a login form and stripe subscription functionality.</p>

<p>When I was using the above middleware to receive <code>stripe webhook secret</code> the server could not receive it.</p>

<pre><code>app.use(express.raw({ type: "application/json" }));
app.use(express.json());
</code></pre>
<p>But now I am unable to receive form JSON data.</p>
<p>Here is my stripe logic:</p>
<pre><code>export const postStripeWebhook = async (req: ExtendedRequest, res: Response) => {
let data;
let eventType;
let event = req.body;
const webhookSecret = "web hook secret provided by stripe";
if (webhookSecret) {
let signature = req.headers["stripe-signature"];
try {
event = stripe.webhooks.constructEvent(req.body, signature , webhookSecret);
} catch (err) {
console.log(`⚠️ Webhook signature verification failed.`); //This part is throwing the error
return res.sendStatus(400);
}
data = event.data;
eventType = event.type;
} else {
data = req.body.data;
eventType = req.body.type;
}
let subscription;
switch (eventType) {
// Here webhook events are managed
}
res.sendStatus(200);
};
</code></pre>
<p>Here is the index.js code:</p>
<pre><code>
app.use(express.raw({ type: "application/json" }));
app.use(express.json());
app.use(express.static("public"));
app.use(express.urlencoded({ extended: true }));
app.use(cors());
app.post("/webhooks", postStripeWebhook);
</code></pre>
<p>Updated code-------------------------</p>
<p>index.js:</p>
<pre><code>app.use(express.json());
app.use(express.static("public"));
app.use(express.urlencoded({ extended: true }));
app.use(cors());
app.post("/webhooks", postStripeWebhook);
</code></pre>
<p>Middleware code:</p>
<pre><code>export const postStripeWebhook = async (req: ExtendedRequest, res: Response) => {
let data;
let eventType;
let event = req.body;
const webhookSecret = "web hook secret provided by stripe";
if (webhookSecret) {
let signature = req.headers["stripe-signature"];
try {
event = stripe.webhooks.constructEvent(JSON.stringify(req.body), signature , webhookSecret); //updated this line
} catch (err) {
console.log(`⚠️ Webhook signature verification failed.`); //This part is throwing the error
return res.sendStatus(400);
}
data = event.data;
eventType = event.type;
} else {
data = req.body.data;
eventType = req.body.type;
}
let subscription;
switch (eventType) {
// Here webhook events are managed
}
res.sendStatus(200);
};
</code></pre>
<p>I updated the code but still, but the problem persists.</p>
<p>Please guide me on how to modify my middleware to receive both types of data.</p>

74,413,034 | <p>So, I have a ball and some obstacles, which disallow the ball to move to the target. Ball is shotting bullets and after each shot I'm checking if the ball can reach the target. I need the ball to stay on starting position until the path is clear. Unfortunately, even if some obsacles are on the way, the ball keeps moving until countering them.</p>
<p>That's what I've tried to do:
`</p>
<pre><code> private void TryReachTheTarget()
{
if (NavMesh.CalculatePath(_agent.transform.position, _target.position, NavMesh.AllArea s, _path) && _path.status == NavMeshPathStatus.PathComplete)
{
_agent.SetPath(_path);
}
}

74,413,043 | <p>I have a websocket server that sends an object containing some hashes every 15 seconds. When the client receives a hash, I want to check with my current hash. If they differ, I want to make a call to an API to fetch new data.</p>
<p>The socket is working and sending the hash correctly. If the data updates on the server I get a different hash. My problem is that the hash variable I use to store the current hash is not updated correctly.</p>
<p>I have disabled the socket listening in my component, just to make sure that that is not the problem. Instead I have added a <code>setInterval</code> to mimik the socket update.</p>
<p>This is my code (socked code disabled but left as a comment):</p>
<pre><code>import { useCallback, useEffect, useState } from "react";
import { useAuth, useSocket } from "../utils/hooks";
const Admin = () => {
const [ questionLists, setQuestionLists ] = useState<QuestionListModel[]>([]);
const { user } = useAuth();
const { socket } = useSocket();
const [ hash, setHash ] = useState<Hash>({questionList: ""});
const fetchHash = useCallback(async () => {
setHash({questionList: "sdhfubvwuedfhvfeuvyqhwvfeuq"});
}, []);
const fetchQuestionLists = useCallback(async () => {
console.log("fetching new question lists");
const response: ApiResponse | boolean = await getQuestionLists(user?.token);
if (typeof response !== "boolean" && response.data) {
setQuestionLists(response.data);
}
}, [hash]);
useEffect(() => {
fetchHash();
fetchQuestionLists();
}, []);
const update = useCallback((newHash: Hash) => {
console.log("called update");
let shouldUpdate = false;
let originalHash = { ...hash };
let updatedHash = { ...newHash };
console.log("new: ", newHash);
console.log("stored: ", originalHash);
if (hash.questionList !== newHash.questionList) {
console.log("was not equal");
updatedHash = { ...updatedHash, questionList: newHash.questionList}
shouldUpdate = true;
}
if (shouldUpdate) {
console.log("trying to set new hash: ", updatedHash);
setHash(updatedHash);
fetchQuestionLists();
}
}, [hash]);
/*useEffect(() => {
socket?.on('aHash', (fetchedHash) => update(fetchedHash));
}, []);*/
useEffect(() => {
setInterval(() => {
update({questionList: "sdhfubvwuedfhvfeuvyqhwvfeuq"});
}, 15000)
}, []);
return (
<>
... Things here later ...
</>
);
};
export default Admin;
</code></pre>
<p>After the initial render, and waiting two interval cycles, this is what I see in the console:</p>
<pre><code>fetching new question lists
called update
new: {questionList: 'sdhfubvwuedfhvfeuvyqhwvfeuq'}
stored: {questionList: ''}
was not equal
trying to set new hash: {questionList: 'sdhfubvwuedfhvfeuvyqhwvfeuq'}
fetching new question lists
called update
new: {questionList: 'sdhfubvwuedfhvfeuvyqhwvfeuq'}
stored: {questionList: ''}
was not equal
trying to set new hash: {questionList: 'sdhfubvwuedfhvfeuvyqhwvfeuq'}
fetching new question lists
</code></pre>
<p>You can see that <code>stored</code> is empty. That leads me to believe that <code>setHash(updatedHash);</code> never runs for some reason. Why is that?</p>

74,413,126 | <p>I would like to write a bash script for transferring multiple directories from a Raspberry Pi to my laptop using scp command. But my code only work on one laptop (MacBook Pro 2016), but it failed on another laptop (MacBook Pro 2020), which is quite strange.</p>
<p>What I would like to execute is some command like:</p>
<pre><code>scp -rp pi@192.168.0.163:/home/pi/Documents/data/{directory1,directory2,directory3} .
</code></pre>
<p>This command work well when I directly execute it in terminal, on both of the laptop. But when I put it into a bash script:</p>
<pre><code>#!/bin/bash
scp -rp "pi@192.168.0.163:/home/pi/Documents/data/{directory1,directory2,directory3}" "."
</code></pre>
<p>it shows error <code>scp: /home/pi/Documents/data/{directory1,directory2,directory3}: No such file or directory</code> on my MacBook Pro 2020, but it works well on my MacBook Pro 2016.</p>
<p>I have checked the bash version on both laptop, but it seems like they don't have too much difference</p>
<blockquote>
<p>MacBook Pro 2016: GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin21)<br />
MacBook Pro 2020: GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin22)</p>
</blockquote>
<p>Can anyone help me?</p>
<p>-------------------------------- Below are updates --------------------------------</p>
<p>Seem like I didn't explain my problem very well.</p>
<p>My actual situation is a litter more complicated. I am working on a bash script which takes multiple directory as parameter for doing scp from my Raspberry Pi remote. My script.sh is like:</p>
<pre><code>#!/bin/bash
while getopts "hu:" option; do
case $option in
h) # display Help
Help
exit;;
u)
user_list+=("$OPTARG");;
\?) # incorrect option
echo "Error: Invalid option"
exit;;
esac
done
RASPBERRYPI_DATA_PATH="/home/pi/Documents/data"
RASPBERRYPI_ADDR=$1
RASPBERRYPI_USER_NAME="pi"
scp -rp ${RASPBERRYPI_USER_NAME}@${RASPBERRYPI_ADDR}:${RASPBERRYPI_DATA_PATH}/{${user_list[@]// /,}} .
</code></pre>
<p>I execute the script in this way:</p>
<pre><code>./script.sh -u "directory1 directory2" 192.168.0.163
</code></pre>
<p>It shows error: <code>scp: /home/pi/Documents/data/{directory1,directory2}: No such file or directory</code> on my MacBook Pro 2020, but it works well on my MacBook Pro 2016.</p>
<p>I am a novice in bash development. I think I am having some mistake on grammar. But the script works well on my old MacBook Pro, which is quite strange.</p>
<p>Thank you very much for helping me.</p>

74,413,176 | <p>I have a string containing placeholders which I want replace with other strings, but I would also like to split the string whenever I encounter a placeholder.</p>
<p>So, by splitting I mean that</p>
<pre><code>"This {0} is an example {1} with a placeholder"
</code></pre>
<p>should become:</p>
<pre><code>parts[0] -> "This"
parts[1] -> "{0}"
parts[2] -> "is an example"
parts[3] -> "{1}"
parts[4] -> "with a placeholder"
</code></pre>
<p>and then the next step would be to replace the placeholders (this part is simple):</p>
<pre><code>parts[0] -> "This"
parts[1] -> value[0]
parts[2] -> "is an example"
parts[3] -> value[1]
parts[4] -> "with a placeholder"
</code></pre>
<p>I know how to match and replace the placeholders (e.g. <code>({\d+})</code>), but no clue how to tell regex to "match non placeholders" and "match placeholders" at the same time.</p>
<p>My idea was something like: <code>(?!{\d+})+ | ({\d+})</code> but it's not working. I am doing this in JavaScript if Regex flavor is important.</p>
<p>If I can also replace the placeholders with a value in one step it would be neat, but I can also do this after I split.</p>

I tried to search online but I only find references to the url_launcher package which, from what I understand, allows you to open the email app and automatically write to someone, but I don't want this, I just want to open the email app and leave it on the main screen.</p>

74,413,330 | <p>The following code presents a way to add two traces to a Plotly figure:</p>
<pre class="lang-py prettyprint-override"><code>import plotly.graph_objs as go
fig = go.Figure()
fig.add_trace(go.Scatter(
x = [0, 1, 2, 3], y = [1, 2, 3, 4],
mode = 'lines+markers',
name = "Trace 0",
))
fig.add_trace(go.Scatter(
x = [5,6,7,8], y = [1, 2, 3, 4],
mode = 'lines+markers',
name = "Trace 1",

fig.show()
</code></pre>
<p>Which looks like this:
<a href="https://i.stack.imgur.com/2eseR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2eseR.png" alt="enter image description here" /></a></p>
<p>Is it possible to merge these two traces into a single one such that they appear under the same title in the legend and share the same visual properties (i.e, color, markers, etc)? More over, merging these traces should enable toggling the visibility when clicking the title in the legend.</p>

74,413,427 | <p>I have been following all of the tutorials for using <strong>docker compose</strong> with regards to <strong>azure</strong> and have been running into a problem with regards to volumes.</p>
<p>My docker compose file looks like this :</p>
<pre><code>version: '3.7'
services:
app-server:
build:
context: .
dockerfile: Dockerfile
ports:
- "8080:8080"
depends_on:
- db
environment:
SPRING_DATASOURCE_URL: jdbc:mysql://db:3306/shapeshop?useSSL=false&serverTimezone=UTC&useLegacyDatetimeCode=false
SPRING_DATASOURCE_USERNAME: root
SPRING_DATASOURCE_PASSWORD: root
SERVER_PORT: 8080
networks:
- backend
db:
image: mysql:5.7
ports:
- "3306:3306"
restart: always
environment:
MYSQL_DATABASE: shapeshop
MYSQL_USER: admin
MYSQL_PASSWORD: admin
MYSQL_ROOT_PASSWORD: root
volumes:
- "db-data:/var/lib/mysql"
networks:
- backend
volumes:
db-data:
driver: azure_file
driver_opts:
share_name: shapeshopfileshare
storage_account_name: shapeshopstorageaccount
networks:
backend:
</code></pre>
<p>In the above YML file I am defining the <strong>volume</strong> for the mysql container (db) to point to azure artifacts. The tutorials state that I should use "azure_file" as a driver and then create a file share and a storage account.</p>
<p>I created both of these (shapeshopfileshare and shapeshopstorageaccount):</p>
<p><a href="https://i.stack.imgur.com/Se5GP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Se5GP.png" alt="enter image description here" /></a></p>
<p>Now if I log into "az" CLI like so :</p>
<pre><code>az login
</code></pre>
<p>I see my subscription "<strong>shapeShopResourceGroup</strong>"</p>
<pre><code> {
"id": "/subscriptions/8cdb50cb-ede8-4eac-80df-55afadf861cd/resourceGroups/shapeShopResourceGroup",
"location": "eastus",
"managedBy": null,
"name": "shapeShopResourceGroup",
"properties": {
"provisioningState": "Succeeded"
},
"tags": null,
"type": "Microsoft.Resources/resourceGroups"
},
</code></pre>
<p>I am also using the "aci" context :</p>
<p><a href="https://i.stack.imgur.com/IRrUn.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/IRrUn.png" alt="enter image description here" /></a></p>
<p>However when I do <strong>docker compose up</strong> I get this error :</p>
<blockquote>
<p>error: The storage account named <strong>shapeshopstorageaccount</strong> is already
taken.</p>
</blockquote>
<p>This is really frustrating to me because, yes, <strong>shapeshopstorageaccount</strong> DOES EXIST! I created it for ME!</p>
<p>So then, I think somehow my <strong>context</strong> does not associate properly with my <strong>subscription</strong>. So to check I type in :</p>
<pre><code>az storage account list
</code></pre>
<p>...and my <strong>shapeshopstorageaccount</strong> is listed in the returned JSON. So it <em>seems</em> like the association between my storage account and subscription exists.</p>
<p>Why is azure (or docker-compose) not associating the declared volume in my YML file with the azure storage that I created??</p>

74,413,505 | <p>I want to do strict matching on a text file so that it only returns the patterns I have anded. So for example in a file:</p>
<pre><code>xyz
xy
yx
zyx
</code></pre>
<p>I want to run a command similar to:</p>
<pre><code>awk '/x/ && /y/' filename.txt
</code></pre>
<p>and I would like it to return only the lines.</p>
<pre><code>yx
xy
</code></pre>
<p>and ignore the others because although they do contain an x and a y, they also have a z so they are ignored.</p>
<p>Is this possible in awk?</p>

74,413,601 | <p>So I've a 2D-array looking like this:</p>
<pre><code>[[1 0]
[2 0]
[3 0]
[4 0]
...
</code></pre>
<p>and I want to save it to a csvfile, I know that I must use to_csv to do so.</p>
<p>So I tried doing :
np.savetxt("file.csv",array,delimiter=',',fmt='%d,%d'), %d is to store data as int not as the default format
But my csv file only contains the first column and not the column of zero.</p>

74,413,649 | <p>I have a dictionary:
where 0 and 1 are two index and the other numbers inside the two dictionaries are the frequency of each word in a previous list of strings</p>
<p>letter_positions={0: {'l': 1, 'y': 2, 'm': 1, 'r': 2}, 1: {'t': 2, 'e': 1, 'n': 1, 's': 3}}</p>
<p>I get that by a function that return a dictionary with the most frequent character of a string by index.</p>
<p>Now I'm using this function to get the most frequent character for each index:</p>
<pre><code>final_dict = {}
for idx, counts in letter_positions.items():
most_popular = max(counts.items(), key=lambda v: v[1])
final_dict[idx] = most_popular[0][0]
</code></pre>
<p>The problem is that in the index 0 of the dictionary the most frequent characters are 'y' and 'r', my code return me 'y' in the final_dict dictionary, but I want to get the lowest alphabetic character 'r'.</p>
<p>How can I edit my code or what do I have to add here</p>
<pre><code> most_popular = max(counts.items(), key=lambda v: v[1])
</code></pre>
<p>to perform my need? thanks</p>

74,413,742 | <p>I am trying to filter an array of objects based on user input.</p>
<p>I wish filter based on the values of certain keys within the object. However, not all the objects have all keys inside them. This means when I check it throws an error.</p>
<p>How do I ignore if a particular object does not have one of the keys inside it and continues to output the matching objects?</p>
<p>Here is some sample data.</p>
<pre><code>const data = [
{
name: "John Miller",
age: 33,
location: "Chicago",
address: '1 help street'
},
{
name: "Jane Doe",
age: 78,
address: '1 help me please lane'
},
{
name: "Jamie Stevens",
location: "San Diego",
age: 32
}
]
</code></pre>
<p>The second object does not have 'location' as a key and the third object does not have 'address' as a key.</p>
<pre><code>const handleSearch = (query) => {
const keys = ['name', 'location', 'address']
const filter = data.filter((row) => (
keys.some((key) => (row[key].toLowerCase().includes(query))
)))
setFilteredData(filter)
}
</code></pre>
<p>Thank you,</p>

74,413,762 | <p>I have this problem where I am asked to multiply BX by 42 without using any <code>mul</code> or <code>div</code> instructions, presumably by using <code>shl</code> or <code>shr</code>. It is also required to do it in 5 lines.</p>
<p>How do you do such a thing ?</p>
<p>I didn't try anything, but the above requirement was to multiply BX by 32 in 1 line, so I just used <code>SHL BX, 5</code>.</p>

74,413,770 | <p>I'm dealing with a csv that repeats its headers name within each rows:</p>
<pre><code>player: John Doe ; level: 45 ; last_login: 7854414174 ; coins: 7600
player: Anckx Uj ; level: 471 ; last_login: 7854418847 ; coins: 684111
</code></pre>
<p>I'd like to know how I can only select the values when importing it using pandas so that the output looks like this:</p>
<pre><code>Player level last_login coins
John Doe 45 7854414174 7600
Anckx Uj 471 7854418847 684111
</code></pre>
<p>I tried adding the header parameter as I thought it would filter out the repeating in the rows, without success.</p>
<ul>
<li><code>import pandas as pd df = pd.read_csv('base.txt', sep=';', header=None, names=['player', 'level', 'last_login', 'coins']</code>
returns me exactly the same thing as the csv (without the delimiter)</li>
</ul>
<p>*Any help would be appreciated</p>

74,413,793 | <p>Is there any data types of nothing available in javascript? I mean like not the null or undefined or 'empty string' but pure nothing. For example, i want to print a variable to console; <code>console.log(variable)</code> it should prints nothing. Is there something like that? Because i needed in do operations in array. Like <code>[x === true ? "Script": `!this should be nothing not empty string but nothing!`]</code> if i print that array i want to see just empty array not null or undefined in that array.</p>

e.g:
input: <code>Why little Dora herself came crying loud</code>
output:</p>
<pre><code>a **
e ****
i **
o **
u *
zero (mentions how many times "the" was used)

<p>I couldn't get to find how to put (*) as in times that letter was used in the sentence but I could just take them out as numbers.</p>

74,413,867 | <p>I would like to iterate over a html collection return by the getElementByClassName function.
I would like to use the setAttribute method to add "table-info" to the class attribute of the elements within the collection.</p>
<p>My problem is that not all elements are modified, to be specific, only the 1st element of the collection does not change its class. It is especially confusing for me that if I hardcode the for-loop, the result I wanted is still not achieved.

74,413,875 | <p>I'm trying to fetch from a table on another sheet, the IDs that have 2 values in common.</p>

<p>I was trying with this formula but it's not working. Even if it would, I think it would probably retrieve the 1st match, not all matches but it was a start, I guess.</p>
<pre><code>=ArrayFormula(VLOOKUP($A$2:$A" "&$B$2:$B,{'To be fetched'!$A$2:$A&" "&'To be fetched'!$C$2:$C,'To be fetched'!$D$2:$D},3,false))

74,413,924 | <p>I have a data like this:</p>
<pre class="lang-js prettyprint-override"><code>[
{
id: "1",
parent: null
},
{
id: "2",
parent: null
},
{
id: "3",
parent: "1"
},
{
id: "4",
parent: "3"
},
]
</code></pre>
<p>And I want to convert it to a tree with a specific maximum depth. There are a few ways to convert an array to a tree, for example <a href="https://www.npmjs.com/package/performant-array-to-tree" rel="nofollow noreferrer">this package</a> but the problem is they go all the way trough and create a deeply nested tree:</p>
<pre class="lang-js prettyprint-override"><code>[
{
data: { id: "1", parent: null },
children: [
{
data: { id: "3", parent: "1" }
children: [
{
id: "4", parent: "3"
}
]
}
]
},
{
data: { id: "2", parent: null }
}
]
</code></pre>
<p>I don't want the depth of the tree be more than a specific amount, let say 1:</p>
<pre class="lang-js prettyprint-override"><code>[
{
data: { id: "1", parent: null },
children: [
{
data: { id: "3", parent: "1" }
},
{
data: { id: "4", parent: "3" }
}
]
},
{
data: { id: "2", parent: null }
}
]
</code></pre>
<p>One way is to first create the deeply nested object and then flatten the parts that I don't want to be nested, but it might change the order of items + it's inefficient. I've had a couple of tries to create an algorithm myself but I'm not generally good at these type of stuff. I would appreciate some help. Idea, example, anything could be useful.</p>

74,413,926 | <p>I am looking for a way to make <code>split(A, B, L)</code> to exhaustively enumerate a B-elements list L such that sum of L's elements equals to A.</p>
<h3>Example</h3>
<pre><code>?- split(s(s(s(s(0)))), s(s(s(0))), L) % splitting 3 to 4 natural numbers
L = [0, 0, 0, s(s(s(0)))];
L = [0, 0, s(0), s(s(0))];
L = [0, 0, s(s(0)), s(0)];
L = [0, 0, s(s(s(0))), 0];
...
L = [s(0), 0, 0, s(s(0))];
...
L = [s(s(s(0))), 0, 0, 0];
false.
</code></pre>
<p>My idea was to extend a list from smaller ones; for example, if <code>split(3, B, [e1, e2, e3])</code> is true, <code>split(4, B+a, [a, e1, e2, e3])</code> is also true (the inline code is not accurate; I used to convey my idea).</p>
<p>Thus I wrote a code as follows.</p>
<pre><code>split(0, 0, []).
split(s(0), B, [B]).
split(s(A), X, [Y|L]) :- split(A, B, L), add(Y, B, X).
</code></pre>
<p>Where</p>
<pre><code>add(0, B, B).
add(s(A), B, s(C)) :- add(A, B, C).
</code></pre>
<p>However, when I run this code, the program doesn't stop and fails.<br />
How should I fix it? Any advices would help.</p>

if row["GovKeepSecure", "BankKeepSecure", OtherKeepSecure] == ["Yes", "Yes", "No"]:

df["Secure"] = df.apply(lambda row: secure(row), axis=1)

74,414,001 | <p>Consider i have a list of lists like below</p>
<pre><code>mylist = [(1, "Laprovitola", "Italy")]
</code></pre>
<p>Imagine i have 1000 sublists. I'd like to make a format of</p>
<pre><code> mydict = [{
"ID": "1",
"Name": "Laprovitola",
"CountryOfResidence": "Italy"}
]
</code></pre>
<p>etc...
The dict should have 8 values in total ID name country and more.
any solution on this?</p>
<p>I have tried the previous solution but have not worked on my hard-coded Dict.</p>

74,414,003 | <p>I have a dataframe with two columns called df['job_title'], df['job_industry_category'], I have a dictonary_of_jobs where there's for every job_title appended a value that's a list of every job category where the job title appears,
as follows:</p>
<pre><code>dictonary_of_jobs =
{'Tax Accountant' : ['Health', 'Financial Services', 'Property', 'IT'],
'Office Assistant': ['Financial Services', 'Property', 'Manufacturing']}
data = [['Tax Accountant', np.nan], ['Office Assistant', np.nan], ['Tax Accountant', np.nan]]
df = pd.DataFrame(data, columns=['job_title', 'job_category'])
</code></pre>
<p>I would like to choose randomly a job category from dictonary and replace that value in my dataframe, where df['job_industry_category'] all consists of Nan values, but nothing's changed.
I tried the .replace method and .at method,
Why is that?</p>
<pre><code>for w,z in zip(df['job_title'], df['job_industry_category']):
for x,y in dictonary_of_jobs.items():
if w == x:
#df.at[z,'job_category'] = random.choice(y)
df['job_title'].replace(z, random.choice(y))
</code></pre>
<p>I expected to have a value from dictonary, but nothing happened.</p>

74,414,013 | <p>I have dictionaries within a list like this:</p>
<pre><code>[{'market': 'singapore', 'abbreviation': 'sg', 'indexId': 'STI', 'indexName': 'STRAITS TIMES INDEX'}, {'market': 'thailand', 'abbreviation': 'th', 'indexId': 'SET100', 'indexName': 'SET100 INDEX'}, {'market': 'turkey', 'abbreviation': 'tr', 'indexId': 'XUTEK', 'indexName': 'BIST TEKNOLOJI'}, {'market': 'thailand', 'abbreviation': 'th', 'indexId': 'SET50', 'indexName': 'SET50 INDEX'}]

74,414,045 | <p>I'm reasonably new to Kotlin and android as a whole. I'm trying to figure out a way to take input through an EditText and add it to an array by pressing a button to accept the values but I can't seem to figure it out. I have been trialing many options and nothing seems to work for me. Below I have pasted my current code. Any Help would be very appreciated because i'm stuck at the moment. Thanks in advance!</p>
<pre><code>class MainActivity2 : AppCompatActivity() {
private lateinit var addnumber: EditText
private lateinit var storednumber: TextView
private lateinit var output: TextView
private lateinit var addbutton: Button
private lateinit var clearbutton: Button
private lateinit var averagebutton: Button
private lateinit var minmaxbutton: Button
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main2)
storednumber = findViewById(R.id.stored_tv)
output = findViewById(R.id.answer2_tv)
addbutton = findViewById(R.id.addNum_btn)
clearbutton = findViewById(R.id.clear_btn)
averagebutton = findViewById(R.id.average_btn)
minmaxbutton = findViewById(R.id.minMax_btn)
addbutton.setOnClickListener {
val ed = findViewById<View>(R.id.et_addNum) as EditText
var text = ed.text.toString()
val arr =
IntArray(text!!.length / 2) //Assuming no spaces and user is using one comma between numbers
var i = 0
while (text != null && text.length > 0) {
arr[i] = text.substring(0, 1).toInt()
text = text.substring(text.indexOf(",") + 1)
i++
}
}
}
