<p>I am trying to deploy my react application on netlify. It is working fine on my desktop and even <code>npm run build</code> is properly working. The material ui packages that I am using are also working fine on my desktop but when I am deploying on netlify the build fails. This is the error log</p>

<p>I can't able to use flexWrap property inside the ScrollView container.</p>
<p>My code looks like this</p>
<pre><code>function Home({ navigation }) {
return (
<View style={styles.container}>
<ScrollView style={styles.scrollContainer}>
<LayoutButton
navigation={navigation}
title={"go to setting"}
path="Setting"
/>
<LayoutButton
navigation={navigation}
title={"go to setting"}
path="Setting"
/>
<LayoutButton
navigation={navigation}
title={"go to setting"}
path="Setting"
/>
<LayoutButton
navigation={navigation}
title={"go to setting"}
path="Setting"
/>
</ScrollView>
<StatusBar style="auto" />
</View>
);
}
</code></pre>
<p>and styles for this is</p>
<pre><code>const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: "#fff",
alignItems: "center",
justifyContent: "center",
flexWrap: "wrap",
},
scrollContainer: {
backgroundColor: "#B7C3F3",
width: "100%",
flexWrap: "wrap",
},
});

<p>I have a master-detail page in blazor wasm: a left panel with a list of items, and a right panel with the selected item.</p>
<p>An example (ascii generated <a href="https://asciiflow.com/#/share/eJyrVspLzE1VssorzcnRUcpJrEwtUrJSqo5RqohRsrI0M9GJUaoEsowsDIGsktSKEiAnRkkBAnwdg0NcgxRwABfXEEdPn5iYvEdT9gxdBHG%2FQmZJaq6CIYr%2FQMJEAoQ52CVpZA7Y0Ub4zKEQkezuR9Mmko%2FIsw8SCLS1g95%2Boq99dE4jkGRrjC5JujnYJQfMnIEJRxOK3Y1DcsDMGboI6H4gQvNXRklJQbGVvn55ebleakVibkFOql5yfq4%2BKPb0jWKUapVqAUgyQu8%3D" rel="nofollow noreferrer">here</a>), with item 2 selected:</p>
<pre><code> MASTER DETAIL
+--------------------+----------------------------------------+
| item 1 | |
| | |
| | item 2 |
+--------------------+ |
|░░░░░░░░░░░░░░░░░░░░| |
|░item 2░░░░░░░░░░░░░| |
|░░░░░░░░░░░░░░░░░░░░| |
|░░░░░░░░░░░░░░░░░░░░| |
+--------------------+ |
| item 3 | |
| | |
| | |
+--------------------+ |
| item 4 | |
| | |
| | |
+--------------------+----------------------------------------+
https://www.example.com/items/2
</code></pre>
<p>URLs:</p>
<ul>
<li><code>/items</code> for page showing items without a selection</li>
<li><code>/items/2</code> for page showing items with item 2 selected</li>
</ul>
<p>I managed to do all that, using this approach:</p>
<ul>
<li><code>MyLayout.razor</code> has a <code><Master /></code> component (left), and a <code><Detail Id=_selectedId /></code> component (right)</li>
<li>When an item is clicked in the master component (left), it raises an event with the <code>Id</code></li>
<li>The layout handles that event, and passes the id to the detail component (right)</li>
<li>The detail component (right) shows the new item</li>
</ul>
<p>I also want the browser's location updated from <code>/items</code> to <code>/items/2</code>, so I used: <code>NavigationManager.NavigateTo("/items/" + id)</code>. <strong>But that reloads all components</strong>.</p>
<p>Workarounds:</p>
<ul>
<li>I haven't found a way to update the browser location without reloading the page (though I could do that in javascript). Even if that were possible, I'm not sure that's a good way to do it.</li>
<li>I could use a query string parameter instead, <code>/items?id=10</code>, then the <code>NavigationManager</code> would (I think) avoid the rerendering - but I can't use this approach, it must be part of the URI.</li>
</ul>
<p>What is the recommended way to handle master-detail navigation in blazor?</p>

<p>I am learning the backend in node. I am trying to execute the following piece of code
`</p>
<pre><code>const axios= require('axios')
async function getData(){
const resp = await axios.get('https://jsonplaceholder.typicode.com/todos/1')
console.log('hello',resp.data)
}
getData()
</code></pre>
<p>I am getting output like this:
<a href="https://i.stack.imgur.com/0V1fG.png" rel="nofollow noreferrer">My output</a></p>
<p>The expected output is: <a href="https://i.stack.imgur.com/lQDpE.png" rel="nofollow noreferrer">expected output</a></p>
<p>I tried running code with <code>node index.js</code> and with extension <code>code runner</code>. The output is the same, even on replit I am getting the same result.
Can someone explain, what am i doing wrong?</p>

<p>I have a list of integers like this</p>
<pre><code>numbers = [1, 5, 7, 19, 22, 55]
</code></pre>
<p>I want to have a function that takes this as input and gives me a list of paired tuples that should contain the numbers as <code>(1,5), (5,7), (7,19)</code> and so on.</p>
<p>Kindly suggest.</p>
<p>I have tried using for loops. Didn't get expected output.</p>

<p>I'm creating an app with firebase as a database. After sending data to firebase, app screen should pop out for that I had bloclistener on the screen but after sending the data to firestore database, nothing is happening, flow is stopped after coming to loaded state in bloc file why? check my code so that you will know. I can see my data in firebase but it is not popping out because flow is not coming to listener.</p>
<pre><code> state:
class SampletestInitial extends SampletestState {
@override
List<Object> get props => [];
}
class SampletestLoaded extends SampletestState {
SampletestLoaded();
@override
List<Object> get props => [];
}
class SampletestError extends SampletestState {
final error;
SampletestError({required this.error});
@override
List<Object> get props => [error];
}
bloc:
class SampletestBloc extends Bloc<SampletestEvent, SampletestState> {
SampletestBloc() : super(SampletestInitial()) {
on<SampletestPostData>((event, emit) async {
emit(SampletestInitial());
try {
await Repo().sampleTesting(event.des);
emit(SampletestLoaded());
} catch (e) {
emit(SampletestError(error: e.toString()));
print(e);
}
});
}
}
Repo: ---- Firebase post data
Future<void> sampleTesting(String des) async {
final docTicket = FirebaseFirestore.instance.collection('sample').doc();
final json = {'Same': des};
await docTicket.set(json);
}
TicketScreen:
//After clicking the button ---
BlocProvider<SampletestBloc>.value(
value: BlocProvider.of<SampletestBloc>(context, listen: false)
..add(SampletestPostData(description.text)),
child: BlocListener<SampletestBloc, SampletestState>(
listener: (context, state) {
if (state is SampletestLoaded) {
Navigator.pop(context);
print("Popped out");
}
},
),
);

<p>I have two programs.
1:</p>
<pre><code>#include <iostream>
using namespace std;
int main () {
do {
cout<<"Hello world";
char yn='y';
} while (yn=='y' || yn=='Y');
return 0;
}
</code></pre>
<p>2:</p>
<pre><code>#include <iostream>
using namespace std;
int main () {
char yn='y';
do {
cout<<"Hello world";
} while (yn=='y' || yn=='Y');
return 0;
}
</code></pre>
<p>First program is showing error like this:</p>
<pre class="lang-none prettyprint-override"><code>comparison between pointer and integer ('double (*)(int, double)' and 'char')
} while (yn=='y' || yn=='Y');
</code></pre>
<p>I think both programs are same but still first program is showing error.</p>

<p>I have a dataframe that looks like that:</p>
<pre><code> col1
0 10
1 5
2 8
3 12
4 13
5 6
6 9
7 11
8 10
9 3
10 21
11 18
12 14
13 16
14 30
15 45
16 31
17 40
18 38
</code></pre>
<p>For each cell in 'col1' I calculate a range of values:</p>
<pre><code>df['df_min'] = df.col1 - df.col1 * 0.2
df['df_max'] = df.col1 + df.col1 * 0.2
</code></pre>
<p>For each cell there's a range, I would like to count how many cells in 'col1' in the past xx cells (3 in this example) are within that range, but without a loop as it takes a very long time with my actual model.</p>
<p>I'm trying to achieve this result:</p>
<pre><code> col1 df_min df_max counter
0 10 8.0 12.0 -1
1 5 4.0 6.0 -1
2 8 6.4 9.6 -1
3 12 9.6 14.4 1
4 13 10.4 15.6 1
5 6 4.8 7.2 0
6 9 7.2 10.8 0
7 11 8.8 13.2 2
8 10 8.0 12.0 2
9 3 2.4 3.6 0
10 21 16.8 25.2 0
11 18 14.4 21.6 1
12 14 11.2 16.8 0
13 16 12.8 19.2 2
14 30 24.0 36.0 0
15 45 36.0 54.0 0
16 31 24.8 37.2 1
17 40 32.0 48.0 1
18 38 30.4 45.6 3
</code></pre>
<p>Here's the (messy) code that I could come up with, but I'd really like a faster solution, if possible. Any help would be gladly appreciated.</p>
<pre><code>df = pd.DataFrame({"col1":[10, 5, 8, 12, 13, 6, 9, 11, 10, 3, 21, 18, 14, 16, 30, 45, 31, 40, 38]})
back = 3 # numbers of cells to check back
df['df_min'] = df.col1 - df.col1 * 0.2
df['df_max'] = df.col1 + df.col1 * 0.2
l = []
for window in df.col1.rolling(window=back+1, center=False, closed='right'):
if window.empty:
pass
else:
a = window.iloc[-1]
range_min = a - a * 0.2
range_max = a + a * 0.2
c = 0
if len(window) == back+1:
for b in window:
if (b >= range_min and b <= range_max):
c += 1
c = c-1 # substract 1 because window includes the tested value which is always true
l.append(c)
df1 = pd.DataFrame(l, columns=['counter'])
df = df.join(df1)
print(df)

<p>Take these two list of strings for example.</p>
<pre><code>names = ['Jack', 'Steve', 'Marc', 'Xavier', 'Bob']
names_copy = ['Steve', 'Marc', 'Xavier', 'Bob', 'Jack']
</code></pre>
<p>Essentially I'm trying to find a way to sort <code>names_copy</code> in the same way that <code>names</code> is sorted.</p>
<p>So, a sorted version of <code>names_copy</code> would result in <code>['Jack', 'Steve', 'Marc', 'Xavier', 'Bob']</code></p>
<blockquote>
<p>NOTE: in my program, names_copy is being created with a map, so I cannot use <code>.sort()</code>, <code>sorted()</code> works however.</p>
</blockquote>
<p>I understand the sorted() function takes in a key parameter indicating the sort order, but I'm not too sure how to use it here.</p>

<p>I know already upload answer to this same question but I try them they are not working for me because there is also some some update in selenium code too.
<strong>Getting this Error</strong> <code>selenium.common.exceptions.ElementClickInterceptedException: Message: element click intercepted: Element <div class="up-typeahead-fake" data-test="up-c-typeahead-input-fake">...</div> is not clickable at point (838, 0). Other element would receive the click: <div class="up-modal-header">...</div> </code>, When trying to send my searching keyword in this input with labeled "Skills Search"

<p>I have an array like:</p>
<pre><code>arr = ["100 abc", "ad", "5 star", "orange"];
</code></pre>
<p>I want to sort firstly strings with no numbers at the beginning and then strings with numbers add at the end, omit numbers and sort strings by name alphabetically.</p>
<p>Expected output:</p>
<pre><code>ad, orange, 100 abc, 5 star.
</code></pre>
<p>How can I do that in TypeScript/Angular?</p>

<p>I'm trying to create a custom iterator over a string's characters, with the difference that it "splits" the string into two iterators. Which one is then used in its own <code>next()</code> depends on custom logic.</p>
<pre class="lang-rs prettyprint-override"><code>struct WrappingIter<I> {
iter_1: I,
iter_2: I,
// ...
}
impl<I> WrappingIter<I>
where
I: Iterator,
{
pub fn new(string: &str, start_idx: usize) -> Self {
Self {
iter_1: string[start_idx..].chars(),
iter_2: string[..start_idx].chars(),
// ...
}
}
}
</code></pre>
<p>That gives me this error (for both assignments):</p>
<pre><code> 1 error[E0308]: mismatched types
--> src/lib.rs:38:25
|
29 | impl<I> WrappingIter<I>
| - this type parameter
...
38 | iter_1: string[start_idx..].chars(),
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected type parameter `I`, found struct `Chars`
|
= note: expected type parameter `I`
found struct `Chars<'_>`
</code></pre>
<p>I can't tell why. <a href="https://doc.rust-lang.org/std/str/struct.Chars.html#impl-Iterator-for-Chars%3C%27a%3E" rel="nofollow noreferrer"><code>std::str::Chars</code> implements the <code>Iterator</code> trait</a>, so my logic was that I could directly assign it to <code>WrappingIter</code>'s members. Need I perhaps perform some sort of cast?</p>

<p>I'm cleaning some text data and I've come across a problem associated with removing newline text. For this data, there are not merely <code>\n</code> strings in the text, but <code>\n\n</code> strings, as well as numbered newlines such as: <code>\n2</code> and <code>\n\n2</code>. The latter are my problem. How does one remove this using regex?</p>
<p>I'm working in R. Here is some sample text and what I've used, so far:</p>
<pre><code>#string
string <- "There is a square in the apartment. \n\n4Great laughs, which I hear from the other room. 4 laughs. Several. 9 times ten.\n2"
#code attempt
gsub("[\r\\n0-9]", '', string)
</code></pre>
<p>The problem with this regex code is that it removes numbers and matches with the letter <code>n</code>.</p>
<p>I would like to have the following output:</p>
<pre><code>"There is a square in the apartment. Great laughs, which I hear from the other room. 4 laughs. Several. 9 times ten."
</code></pre>
<p>I'm using <a href="https://regexr.com/" rel="nofollow noreferrer">regexr</a> for reference.</p>

<p>I have a bit complicated PowerQuery query which has many steps. Within these steps I have a date, team and conditions as below (not actual data)</p>
<p><a href="https://i.stack.imgur.com/0UOdJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/0UOdJ.png" alt="enter image description here" /></a></p>
<p>So the challenge is that I want to count the Pass number for each team for each day and then create another count for Pass and Fail and then it will be used in so many calculations which I can handle later.</p>
<p>I have tried many options, like for example grouping, but it was so confusing because as I mentioned before, the query has so many columns and calculations now. I could successfully solve the issue by creating DAX measure, but the issue here that I need to calculate the average outcome which is not possible to because I couldn't also average the measure of the outcome. So I have no other option but to make the countif though PowerQuery.</p>
<p>Appreciate your help and ideas.</p>
<p>Raw data as text is <a href="https://docs.google.com/spreadsheets/d/17LIy4nhdZutfq6xUCf7QL_alSkAVR9yF45BfvKIdk0c/edit#gid=0" rel="nofollow noreferrer">here in google sheets</a></p>

<p>It's really expensive to transfer whole model from server to client specially when loading lists. The solution is to ignore empty, null or default values which can be refilled in client side. Consider a <code>Customer</code> model like this:</p>
<pre><code>export class Customer {
customerId: number = 0;
ncode: string = 'some default text';
name: string = '';
age: int = 20;
isActive: boolean = false;
birthday: Date | null = null;
// And much more fields ...
}
</code></pre>
<p>We have same model in server side and the server will ignore null and default fields in serialization. For example, this is a customer sent from server:</p>
<pre><code>"{'customerId':1234}"
</code></pre>
<p>What happens is that the object created by angular http get, is a <code>Customer</code> with only <code>customerId</code> field! All other fields are undefined.
Is there any solution to fix it globally with no third party library to force angular to value missing fields with their default values?</p>
<p>Update:
Here is the request code:</p>
<pre><code>export class CustomerComponent implements OnInit {
constructor(private http: HttpClient) { }
ngOnInit(): void {
this.http.get<Customer>('/api/getCustomer').subscribe((response) => {
console.log(response); // {'customerId':12345}
});
}
}
</code></pre>
<p>Update 2:
As I thought there may be a global solution, I made a simple example. But we have a generic function to handle all api requests, which is generic and returns <code><T>(<any>response)</code></p>
<pre><code>public request<T>(api: string, method: string = 'GET', formData: any): Observable<T>{
return new Observable((observer: Observer<T>) => {
header = new HttpHeaders({/*...*/});
this.http.request<T>(new HttpRequest(method, api, JSON.stringify(formData), {headers: header}))
.subscribe({next: (response) => {
observer.next(<T>(<any>response)); // <= This line must be changed I think
}});
}
}
</code></pre>

<p>I am new in java. I am trying convert simple java app with terminal output to a app with a GUI or UI. I have seen small java applications with little window , like calculator or currency converter.</p>
<p>This is the program I am trying to convert to a GUI app
<a href="https://github.com/Abhinav-26/Employee-Management-System/blob/master/EmployManagementSystem.java" rel="nofollow noreferrer">https://github.com/Abhinav-26/Employee-Management-System/blob/master/EmployManagementSystem.java</a></p>
<p>I have tried to run this app. I am getting the out put in a terminal. (image 1)<a href="https://i.stack.imgur.com/qh0MH.png" rel="nofollow noreferrer">terminal output</a></p>
<p>I need a UI to this simple app , like image 2 - <a href="https://i.stack.imgur.com/bUB2J.png" rel="nofollow noreferrer">example of ui</a></p>
<p>I am expecting to get a simple java app with UI , like in picture 2. Is there a way to edit existing app ? What should I google / lookup ?</p>

<p>I have example data as follows:</p>
<pre><code>library(data.table)
datA <- fread("ID somevar
NA 4
NA 3
2 5")
datB <- fread("ID somevar
7 4
NA 3
NA 5")
dat_list <- list(datA, datB)
</code></pre>
<p>In dat_list I would like to replace all <code>NA</code>'s in the <code>ID</code> column with a new <code>ID</code>-number.</p>
<p>I would like this number to be unique and start at <code>100</code>. I thought of something like this:</p>
<pre><code>for (i in seq_along(dat_list)){
temp <- dat_list[[i]]
count_of_seq <- sum(is.na(temp$ID))
sequence_dat <- seq(100, 100+count_of_seq)
temp <- setDT(temp)[is.na(ID), ID:=sequence_dat[i]]
}
</code></pre>
<p>But this does not work because, it uses only one number of the sequence for each list:</p>
<p><a href="https://i.stack.imgur.com/bB5M1.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bB5M1.png" alt="enter image description here" /></a></p>
<p>How should I do this properly?</p>
<p>Desired output:</p>
<pre><code>library(data.table)
datA <- fread("ID somevar
100 4
101 3
2 5")
datB <- fread("ID somevar
7 4
102 3
103 5")
dat_list <- list(datA, datB)
</code></pre>

<p>I have 2 objects where I want the second one to be in the same order as the first one.</p>
<p>Ex:</p>
<pre><code>const obj1 = [
{ key: 1, id: 1, name: "John" },
{ key: 2, id: 2, name: "Ann" },
{ key: 3, id: 3, name: "Kate" }
];
const obj2 = [
{ key: 2, id: 2, name: "Ann" },
{ key: 1, id: 1, name: "John" },
{ key: 3, id: 3, name: "Kate" }
];
</code></pre>
<p>The purpose is to have <code>obj2</code> in same order as <code>obj1</code>, but only sort with keys. I'm trying to make an helper function which will pass 3 argument:</p>
<pre><code>function helper(obj1, obj2, key) {
// return new object with sorted array do not modify existing
}
</code></pre>
<p>I can sort one of this, but cant combine 2object together</p>

<p>I have written algorithm that solves the pluszle game matrix.
Input is numpy array.</p>
<p>Now I want to recognize the digits of matrix from screenshot.
<a href="https://i.stack.imgur.com/WUmc7.jpg" rel="nofollow noreferrer">there are different levels, this is hard one</a></p>
<p><a href="https://i.stack.imgur.com/s6z4G.png" rel="nofollow noreferrer">this is easy one</a></p>
<p>the output of recognition should be numpy array</p>
<pre><code>array([[6, 2, 4, 2],
[7, 8, 9, 7],
[1, 2, 4, 4],
[7, 2, 4, 0]])
</code></pre>
<p>I have tried to feed last image to tesseract</p>
<pre><code>from PIL import Image
import pytesseract
pytesseract.pytesseract.tesseract_cmd = r'C:\Program Files\Tesseract-OCR\tesseract.exe'
print(pytesseract.image_to_string(Image.open('C:/Users/79017/screen_plus.jpg')))
</code></pre>
<p>The output is unacceptable</p>
<pre><code>LEVEL 4
(}00:03 M0
J] —.°—@—@©
</code></pre>
<p>I think that I should use contours from opencv, because the font is always the same. maybe I should save contours for every digit, than save every countour that exist on screenshot than somehow make matrix from coordinates of every digit-contour. But I have no idea how to do it.</p>

<p>I would appreciate some help understanding the output of a small educational program I put together. I am new to OpenCV and don't have much C++ experience.</p>
<p>The goal of the script is to perform the following:</p>
<ul>
<li>Load an image</li>
<li>Perform DFT on the image</li>
<li>Apply a circular binary mask to the spectrum, where the radius of the circle can be increased by hitting a key on the keyboard (essentially applying a very crude filter to the image)</li>
<li>Display the result of the inverse transform of the spectrum after the mask was applied</li>
</ul>
<hr />
<p>I have the basic functionality working: I can load the image, perform DFT, view the output image and increase the radius of the circle (advancing through a for-loop with the circle radius following <code>i</code>), and see the result of the inverse transform of the modified spectrum.</p>
<p>However I do not understand why the output is showing a vertically flipped copy of the input superimposed on the image (see example below with <code>Lena.png</code>). This is not my intended result. When I <code>imshow()</code> the inverse DFT result <em>without</em> applying the mask, I get a normal, non-doubled image. But after applying the mask, the IDFT output looks like this:</p>
<p><a href="https://i.stack.imgur.com/FBUrx.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FBUrx.png" alt="Output when normal "Lena.png" is given as input image" /></a></p>
<p><strong>I am not looking for a quick solution: I would really appreciate if someone more experienced could ask leading questions to help me understand this result so that I can try to fix it myself.</strong></p>

<p><strong>Linux bash</strong>: why the two shell script as follow had different result?</p>

<p>I found something in my search, which I don't understand. The goal is to read out the angle of a pointer in a pressure gauge. In my research, I found this example:</p>
<p><a href="https://circuits-ninja.pl/reading-an-indication-from-an-analog-pressure-gauge-using-the-esp32-cam-module-with-an-ov2640-and-opencv-camera/" rel="nofollow noreferrer">https://circuits-ninja.pl/reading-an-indication-from-an-analog-pressure-gauge-using-the-esp32-cam-module-with-an-ov2640-and-opencv-camera/</a></p>
<p>He's calculating the degree as follows:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code># Finding angle using the arc tan of y/x
res = np.arctan(np.divide(float(y_angle), float(x_angle)))
#Converting to degrees
res = np.rad2deg(res)
if x_angle > 0 and y_angle > 0: #in quadrant I
final_angle = 270 - res
if x_angle < 0 and y_angle > 0: #in quadrant II
final_angle = 90 - res
if x_angle < 0 and y_angle < 0: #in quadrant III
final_angle = 90 - res
if x_angle > 0 and y_angle < 0: #in quadrant IV
final_angle = 270 - res</code></pre>
</div>
</div>
</p>
<p>I understand the reason of using quadrants in this case, but what i don't understand is why does he calculate 270 - res
if x_angle and y_angle > 0 and also calculate 270 - res if x_angle > 0 and y_angle < 0.
He's using the same formula for two different quadrants?</p>
<p>Thanks in forward</p>

<p>I'm trying to reverse a string. I use the solution of <a href="https://stackoverflow.com/questions/27996430/reversing-a-string-in-rust">this post</a> and it works.</p>
<p>But I would like to try with bytes instead of grapheme clusters as shown below:</p>
<pre class="lang-rust prettyprint-override"><code>pub fn reverse2(input: &str) -> String {
let s: String = input
.as_bytes()
.iter()
.rev()
.collect();
return s;
}
</code></pre>
<p>Unfortunately, I can't run the function <code>collect()</code> after <code>rev()</code>. I don't know which method to use. How would you do it ?</p>

<p>I have the following vector called <code>input</code>:</p>
<pre><code>input <- c(1,2,1,NA,3,2,NA,1,5,6,NA,2,2)
[1] 1 2 1 NA 3 2 NA 1 5 6 NA 2 2
</code></pre>
<p>I would like to split this vector into multiple vectors by each NA. So the desired output should look like this:</p>
<pre><code>> output
[[1]]
[1] 1 2 1
[[2]]
[1] 3 2
[[3]]
[1] 1 5 6
[[4]]
[1] 2 2
</code></pre>
<p>As you can see every time a <code>NA</code> appears, it splits into a new vector. So I was wondering if anyone knows how to split a vector by each <code>NA</code> into multiple vectors?</p>

<p>I have a txt file that updates with new data every few seconds. It is stored and generated locally on a raspberry pi, which will also act as the server.</p>
<p>I want its contents to be added to and html code for displaying.</p>
<p>It should update without manual reloading of the page.</p>
<p>Is there a way to do this? Maybe with AJAX, PHP, or something along those lines?</p>
<p>Don't have to find/write any code for me, as I understand that it would be rather time consuming. just point me in the right direction so I can learn how to do it.</p>

<p>i need to truncate portions of a string that are found between a regex pattern.</p>
<ul>
<li>if a portion length is <code><=</code> to the given padding, leave the portion as it is.</li>
<li>the starting portion should be truncated from the left.</li>
<li>the ending portion should be truncated from the right.</li>
<li>the portions in between should be truncated in the middle.</li>
<li>if no pattern found, leave the string untouched</li>
</ul>
<p>code:</p>
<pre class="lang-js prettyprint-override"><code>// note that the 'x' characters below could be any characters, even spaces or line breaks.
const str = 'xxxxx<mark>foo</mark>xx<mark>bar</mark>xxxxxxxxx<mark>baz</mark>xxxxxxxx'
const truncateBetweenPattern = (str, pattern, padding=0, sep='...') => {
// code
}
const pattern = '(<mark>.+</mark>)' // (not sure if this is valid)
const result = truncateBetweenPattern(str, pattern, 3)
</code></pre>
<p>output:</p>
<pre class="lang-js prettyprint-override"><code>result === '...xxx<mark>foo</mark>xx<mark>bar</mark>xxx...xxx<mark>baz</mark>xxx...'
</code></pre>

<p>I'm trying to run a python file that imports a module using other modules in the grandparent folder. The file structure is:</p>
<pre><code>directory_0
|
directory_1
| |
| directory_2
| |
| __init__.py (define the method A and import another method B from file_2.py)
| |
| file_1.py
|
directory_3
|
file_2.py (define the method B)
</code></pre>
<p>I want to run <code>file_1.py</code> that <em>imports method A</em> defined in <code>__init__.py</code>, and <code>__init__.py</code> it <em>imports method B from file_2.py</em>.
I'm currently at <code>/directory_0/directory_1/directory_2</code> to run the command <code>python file_1.py</code>. It throws <code>ModuleNotFoundError: No module named directory_3.file_2</code>
How to make it run? and which path should I go to run this script (file_1.py).</p>

<p><a href="https://stackoverflow.com/a/7486111/17273668">https://stackoverflow.com/a/7486111/17273668</a> ; from what I have seen here to make a class "static" , we have to make it final with private constructor and static fields and methods.</p>
<p>Is there any difference between making the constructor private and making the class abstract?</p>

<p>I use fetch() to print labels. There are some scenario when I need to loop through the data and print multiple labels. The printing it's working fine, but after the first loop the script stop running.</p>
<p>I use async function in order to slow down a printing.</p>
<pre><code>async function printing() {
for (let w = 0; w < print_labels.length; w++) {
const label = `data of the label`
fetch('http://111.111.1.111:9100', {
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
},
body: label
})
console.log(`${w}. label printed.`)
await sleep(2000);
}
};
printing()
</code></pre>
<p>Ho can I cancel/stop the fetch() function? Or maybe any other solution how to use fetch() post in for loop?</p>

<p>I just finished implementing a working Python code for the Dijkstra-Pathfinding algorithm. I am applying this algorithm to a graph with edges, which I have written as a list of tuples:</p>
<pre><code>graph = Graph([
("a", "b", 2),("a", "c", 5),
("a", "d", 2),("b", "c", 3),
("b", "e", 1),("c", "e", 1),
("c", "h", 1),("c", "f", 1),
("c", "d", 3),("d", "g", 2),
("e", "i", 7),("f", "h", 3),
("f", "g", 2),("h", "i", 1)])
</code></pre>
<p>I don't want to leave it like that and rather fill the graph using a for-loop, but this is exactly where I fail.</p>
<p>I have tried writing</p>
<pre><code>graph.append(("i", "j", "4"))
</code></pre>
<p>And several other variants using the append function but it just keeps giving me errors.
I am aware that this isn't a for-loop, I am simply trying to add one edge for now.</p>
<p>This is how I defined my add_edge function:</p>
<pre><code>Edge = namedtuple('Edge', 'start, end, cost')
def add_edge(start, end, cost):
return Edge(start, end, cost)
</code></pre>

<p>I'm writing a programme that converts complex numbers.
Right now I'm having problems with this piece of code:</p>
<pre><code>import numpy
complexnr = 1+1j
mod= numpy.absolute(complexnr)
print(mod)
</code></pre>
<p>The output of this code is:</p>
<pre><code>1.4142135623730951
</code></pre>
<p>I would like to get √2 as the output.</p>
<p>I have been advised to use the sympy module but I have had no luck with this either. What would be the easiest way to get this result?</p>
<p>EDIT</p>
<pre><code>input_list = ["Enter your complex number (a+bi): ", \
"Degrees or radians?", \
"To how many decimal places do you want to round the argument?"]
output = multenterbox(text, title, input_list)
algebraline = output[0]
choice = output[1]
round2 = int(output[2])
#converting complex number to a suitable form for numpy
if "i" in algebraline:
j = algebraline.replace("i","j")
indeks = algebraline.index("i")
list = []
for element in algebraline:
list.append(element)
if "i" in algebraline and algebraline[indeks-1]=="+" or algebraline[indeks-1]=="-":
list.insert(indeks, 1)
x = "".join(str(e) for e in list)
j = x.replace("i","j")
arv = eval(j)
elif "i" not in algebraline:
arv = eval(algebraline)
#let's find the module
a = int(list[0])
b = int(list[2])
module = sqrt(a**2+b**2)
</code></pre>
<p>this method works well when the complex number is 1+i for example, however when i try to insert sqrt(3)-1i, the list looks like this ['s', 'q', 'r', 't', '(', '3', ')', '-', 1, 'i'] and my programme won't work. Same problem occurs when b is a root (for example 1-sqrt(3)i). What can be done to make it work for square roots as well? (I need numpy later on to calculate angles, that's why converting 'i' into 'j' is important)</p>

<p>I have a dataframe such as :</p>
<pre><code>Names1 Gene_name Status
SP1 GENE1 0
SP1 GENE1 1
SP1 GENE1 1
SP1 GENE1 2
SP1 GENE1 2
SP1 GENE2 0
SP3 GENE2 0
SP1 GENE2 1
SP2 GENE2 2
SP4 GENE3 1
SP4 GENE3 2
SP5 GENE3 0
SP5 GENE3 0
</code></pre>
<p>Then I would like to fill a new dataframe where each <code>Gene_name</code> is a column, and each <code>Names</code> is a row :</p>
<pre><code>Names GENE1 GENE2 GENE3
SP1
SP2
SP3
SP4
SP5
</code></pre>
<p>and fill cells <code>Values</code> depending on the <code>Satus</code> for each <code>Names</code> groups</p>
<ul>
<li>if only 0 > value = 0</li>
<li>if only 1 > value = 1</li>
<li>if both 0 & 1 > value = 0-1</li>
<li>if both 0 & 2 > value = 0-2</li>
<li>if both 1 & 2 > value = 1-2</li>
<li>if both 0 & 1 & 2 > value = 0-1-2</li>
</ul>
<p>So for example <code>GENE1</code> in <code>SP1</code> both present a 0,1 and 2 status, so I fill <code>0-1-2</code> within the cell:</p>
<pre><code>Names GENE1 GENE2 GENE3
SP1 0-1-2
SP2
SP3
SP4
SP5
</code></pre>
<p>then, <code>SP2,SP3,SP4 and SP5</code> do not have value for the <code>GENE1</code>, so I put <code>NA</code> :</p>
<pre><code>Names GENE1 GENE2 GENE3
SP1 0-1-2
SP2 NA
SP3 NA
SP4 NA
SP5 NA
</code></pre>
<hr />
<p>Then for the <code>GENE2:</code></p>
<p><code>GENE2</code> in <code>SP1</code> both present a 0 and 1 status, so I fill <code>0-1</code> within the cell:</p>
<pre><code>Names GENE1 GENE2 GENE3
SP1 0-1-2 0-1
SP2 NA
SP3 NA
SP4 NA
SP5 NA
</code></pre>
<p><code>GENE2</code> in <code>SP2</code> present only a value 2 status, so I fill <code>2</code> within the cell:</p>
<pre><code>Names GENE1 GENE2 GENE3
SP1 0-1-2 0-1
SP2 NA 2
SP3 NA
SP4 NA
SP5 NA
</code></pre>
<p><code>GENE2</code> in <code>SP3</code> present only a value 0 status, so I fill <code>0</code> within the cell:</p>
<pre><code>Names GENE1 GENE2 GENE3
SP1 0-1-2 0-1
SP2 NA 2
SP3 NA 0
SP4 NA
SP5 NA
</code></pre>
<p>and the other Names have no <code>GENE2</code> values, so I put <code>NA</code>:</p>
<pre><code>Names GENE1 GENE2 GENE3
SP1 0-1-2 0-1
SP2 NA 2
SP3 NA 0
SP4 NA NA
SP5 NA NA
</code></pre>
<p>and so on...
At the end I should get a full dataframe such as :</p>
<pre><code>Names GENE1 GENE2 GENE3
SP1 0-1-2 0-1 NA
SP2 NA 2 NA
SP3 NA 0 NA

<p>Let's say I have a list of ints called <code>List<int> List1 = new() {1,2,3,4}</code> and <code>List<int> List2 = new() {2,3,4}</code>.</p>
<p>I need to check if List2 has everything List1 has. Keep in mind that list lengths may vary.</p>
<p>I have no idea on how to make it. Searching on the internet didnt really help.</p>

<p><br />
I want to filter and get the results of each index that</p>
<p>it's name starts with <code>"abc"</code> and the state is <code>"DISABLED"</code>.</p>
<p>My file looks like this:</p>
<pre class="lang-json prettyprint-override"><code>➜ ~ cat test.json | head
{
"Rules": [
{
"Name": "abcd",
"Arn": "arn:aws:events:eu-west-2:XXXXXX:rule/abcd",
"State": "ENABLED",
"ScheduleExpression": "rate(6 hours)",
"EventBusName": "default"
},
{

"Arn": "arn:aws:events:eu-west-2:XXXXXX:rule/abcxxx",
"State": "DISABLED",
"ScheduleExpression": "rate(12 hours)",
"EventBusName": "default"
}
]
}
</code></pre>
<p>I tried to use this command:</p>
<pre class="lang-bash prettyprint-override"><code>cat test.json | jq -r '.[] | .[] | select(.Name | startswith("abc"))'
</code></pre>
<p>And it's giving me whatever starts with <code>"abc"</code> which is good but I want it to be also<br />
<code>.State == "DISABLED"</code> and I want the output to be regular and not JSON.<br />
(I need to get the names of whatever starts with <code>abc</code> and it's state is <code>DISABLED</code> into a file)</p>

<p>Faced a problem. On the site, i need to generate such a number of certain lines (via document.write("Welcome to my page") ) that the user will tell through the dialog box, when dialog box opening on the page. All this happens through <script> ... </script>. I tried it in different ways, but nothing works. Help me, please.</p>
<pre><code> confirm("Specify how many times to repeat?');
var run() = promt("How many times? {value}')
function run(){
let value = document.getElementById('count').value
if(confirm(Run block ${value} times?)) {
while(value < 0){
document.write(Welcome to my page!<br>')}
}
}
</code></pre>
<p>A friend suggested this, but it doesn't work either.</p>
<pre><code> let res = prompt('How many times?',1)
if(!res || isNaN(Number(res)) || res < 0) {
alert('Invalid quantity entered')
location.reload()
return
}
res = Math.round(Number(res))
while (res > 0){
document.write(`Welcome to my page!<br>')}
res--

<p>What is the default ARIA role of a <code>div</code> or <code>span</code> in HTML? Or, in other words, what is the ARIA role of non-interactive elements and the elements that don't have a specific ARIA role assigned to them? Is it <code>none</code> or <code>presentation</code>? Or is it not defined? And if it is, do they have any different meaning than <code>none</code> or <code>presentation</code>?</p>

<p>I'm trying to make a class in Delphi that handles files. I have a property that returns the size of the file and another one that returns the position of the file. I don't know if any error can happen with these calls. Should I raise an exception?</p>
<p>My code is:</p>
<pre><code>function TFile.GetSize: Int64;
var
FileSizeHi, FileSizeLo: Cardinal;
begin
FileSizeLo := GetFileSize(FHandle, @FileSizeHi);
if (FileSizeLo = INVALID_FILE_SIZE) and (GetLastError = NO_ERROR) then
Result := $FFFFFFFF
else
Result := FileSizeLo or Int64(FileSizeHi) shl 32;
end;
function TFile.GetPosition: Int64;
var
FilePosHi, FilePosLo: Cardinal;
begin
FilePosHi := 0;
FilePosLo := 0;
FilePosLo := SetFilePointer(FHandle, FilePosLo, @FilePosHi, FILE_CURRENT);
if (FilePosLo = INVALID_SET_FILE_POINTER) and (GetLastError = NO_ERROR) then
Result := $FFFFFFFF
else
Result := FilePosLo or Int64(FilePosHi) shl 32;
end;
</code></pre>
<p>I don't know what error could happen when I call GetFileSize or SetFilePointer (without moving the file pointer).</p>

<p>In cpp, <br />
I know <code>&</code> is used to get the address<br />
and <code>::</code> is used to get the member of class,<br />
but, what's the usage of <code>&::</code> ?</p>
<p>Here is the example of the function <code>connect</code> of qt5:</p>
<pre><code>QtWidgetsApplication2::QtWidgetsApplication2(QWidget *parent)
: QMainWindow(parent)
{
ui.setupUi(this);
connect(ui.pushButton_select, &QPushButton::clicked,this,&::QtWidgetsApplication2::select_file);
}
void QtWidgetsApplication2::select_file()
{
file_path = QFileDialog::getOpenFileName(NULL, QStringLiteral("选择文件"), "D:", QStringLiteral("音频文件(*wav)"));
}
</code></pre>
<p>what's the meaning of <code>&::</code> in this line :</p>
<blockquote>
<p>connect(ui.pushButton_select, &QPushButton::clicked,this,<strong>&::QtWidgetsApplication2::select_file</strong>);</p>
</blockquote>
<p>why not <code>&QtWidgetsApplication2::select_file</code>?</p>

<p>I ran into a problem with Redshift. I'm generating a sequence of dates and want to embed it in a table to work with the range. But Redshift only supports generation on the leader node. It is not possible to insert the data on the nodes. Nowhere in the documentation have I found information on how to insert the generated sequences into tables. Maybe someone has encountered such a problem and can share their experience in solving it?
My sequence:</p>
<pre><code>SELECT date '2019-12-31' + INTERVAL AS date_range
FROM generate_series(1, (date '2041-01-01' - date '2020-01-01')) INTERVAL;
</code></pre>
<p>My query:</p>
<pre><code>CREATE TABLE public.date_sequence AS (
SELECT date '2019-12-31' + INTERVAL AS date_range
FROM generate_series(1, (date '2041-01-01' - date '2020-01-01')) INTERVAL
);
</code></pre>
<p>I also tried inserting data from cte. Insert data into a temporary table. The result is the same:
ERROR: Specified types or functions (one per INFO message) not supported on Redshift tables.</p>

<p>Is there a neat way to simplify this if statement?
I need n to be >= 2 and <= 100 and value to increase by one for every seventh step (except the first one which should be between 2 and 7 and last one which should be between 98 and 100).</p>
<pre><code>if n >= 2 and n <= 7:
value = 1
elif n > 7 and n <= 14:
value = 2
elif n > 14 and n <= 21:
value = 3
elif n > 21 and n <= 28:
value = 4
elif n > 28 and n <= 35:
value = 5
elif n > 35 and n <= 42:
value = 6
elif n > 42 and n <= 49:
value = 7
elif n > 49 and n <= 56:
value = 8
elif n > 56 and n <= 63:
value = 9
elif n > 63 and n <= 70:
value = 10
elif n > 70 and n <= 77:
value = 11
elif n > 77 and n <= 84:
value = 12
elif n > 84 and n <= 91:
value = 13
elif n > 91 and n <= 98:
value = 14
elif n > 98 and n <= 100:
value = 15
</code></pre>
<p>EDIT:
Furthermore I'm having trouble finding the smallest number possible from the following question:</p>
<hr />
<p>Matchsticks are ideal tools to represent numbers. A common way to represent the ten decimal digits with matchsticks is the following:</p>
<p><a href="https://i.stack.imgur.com/7PkZJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7PkZJ.png" alt="enter image description here" /></a></p>
<p>This is identical to how numbers are displayed on an ordinary alarm clock. With a given number of matchsticks you can generate a wide range of numbers. We are wondering what the smallest and largest numbers are that can be created by using all your matchsticks.</p>
<p><em>Input:</em></p>
<p>On the first line one positive number: the number of testcases, at most 100. After that per testcase:</p>
<p>One line with an integer n (2 <= n <= 100): the number of matchsticks you have.</p>
<p><em>Output:</em></p>
<p>Per testcase:</p>
<p>One line with the smallest and largest numbers you can create, separated by a single space. Both numbers should be positive and contain no leading zeroes.</p>
<hr />
<p>I've tried multiple different ways to try to solve this problem, I'm currently trying to:</p>
<ol>
<li>find the minimal number of digits (value) for the smallest number:</li>
</ol>
<p>#Swifty</p>
<pre><code>def values(n):
if 2 <= n <= 100:
value = (n + 6) // 7
minimum(n, value)
</code></pre>
<ol start="2">
<li>now i want to send value to a function minimum() which should generate all the different combinations of numbers that are the length of value. I want to store all these numbers in a list and then take min() to get the smallest one. I'm not getting this part to work, and would appreciate some inspiration.</li>
</ol>
<p>Something to remember is that the number can't start with a 0.</p>

<p>I'm building my first app using RTK query.
I need to set my authorization token in my headers. It is stored in a cookie, but they can't be accessed from the apiSlice, which means I need to store the token in my states which I'd have access to when setting my headers.</p>
<p>I get the token from my cookies when the app first starts, but I'm failing to understand how do I store it in my state, now that I use RTK query? I'm not making any API call, I already have the data. How do I store it in my slice?</p>

<p>I'm building a Formula1 race simulator in python and I'm trying to make a overtake function, basically, i've all the drivers stored in a list and once one of the drivers surpasses the other I need to invert their position in the list</p>
<pre><code>['hamilton','vertsappen','perez','sainz']
['hamilton','perez','verstappen','sainz']
</code></pre>
<p>is there any way to do so?</p>
<p>since now I have tried to store the original positions in a temporary variable but I keep finding myself with duplicates in the list</p>
<p>original temporary variables</p>
<pre><code>overtaken temp = Valteri Bottas
overtaker temp = Nicholas Latifi
</code></pre>
<p>after the inverting</p>
<pre><code>overtaken temp = Valteri Bottas
overtaker temp = Valteri Bottas
</code></pre>

<p>I tried to create several maps and saved as png files. In cycle I got all mapes per <code>year</code>. I want to add which year on the map, and I tried <code>title=i</code> and <code>fig.update_layout(title_text=i, title_x=0.5)</code>, but it does not work.</p>
<pre><code>import plotly.express as px
import pandas as pd
year = [1980,1981,1983]
lat = [60.572959, 60.321403, 56.990280]
lon = [40.572759, 41.321203, 36.990299]
dataframe = pd.DataFrame(list(zip(year,lat,lon)),
columns =['year', 'lat', 'lon'])
for idx, i in enumerate(sorted(dataframe['year'].unique())):
#for x in range(1980,2022):
sp = sp1[sp1['year']==i]
fig = px.scatter_mapbox(dataframe, lat='lat', lon="lon",

<p>I have a nested list like:</p>
<pre><code>[["bla","blabla","x=17"],["bla","x=13","z=13","blabla"],["x=27","blabla","bla","y=24"]]
</code></pre>
<p>I need to have this sorted by x (from least to most) as (other strings should stay where they are):</p>
<pre><code>[["bla","x=13","z=13","blabla"],["bla","blabla","x=17"],["x=27","blabla","bla","y=24"]]
</code></pre>
<p>and also from most to least:</p>
<pre><code>[["x=27","blabla","bla","y=24"],["bla","blabla","x=17"],["bla","x=13","z=13","blabla"]]
</code></pre>
<p>I think I have to use key=lambda but I just couldn't figure out how to do it. Searched through the web and this website but I just can't do it.</p>

<p>Fair Warning: I'm a student trying to build an app for our research.</p>
<p>So I'm Trying to build an app where the user Defines the amount of Q/A he/she wants, then the app will ask for the user to put different Q/A until it reaches the an equal amount where it will then open up a new page to make the user answer those Q/A.</p>
<p>The Problem is that the Loop fails to repeat at the stated amount by user making the app not being able to store let's say 10 Q/A to the JShared / Shared Preference.</p>
<p>Here's the loop code:</p>
<pre><code>package com.prgr.quizards.canary;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
import androidx.appcompat.widget.AppCompatButton;
import com.google.android.material.textfield.TextInputEditText;
import com.google.gson.Gson;
import java.util.HashMap;
import java.util.Objects;
public class question extends Activity {
private HashMap<String, Object> map = new HashMap<>();
private TextView text;
private EditText inop;
private TextInputEditText ans;
private AppCompatButton btn;
private SharedPreferences jshared2;
private SharedPreferences jshared;
@Override
protected void onCreate(Bundle _savedInstanceState) {
super.onCreate(_savedInstanceState);
setContentView(R.layout.activity_question);
initializedata();
AppCompatButton btn2 = findViewById(R.id.button3);
btn = findViewById(R.id.button);
btn2.setOnClickListener(v -> gotoback());
btn.setOnClickListener(view -> logicg());
}
public void gotoback(){
Intent intent = new Intent(question.this, activity_home_screen.class);
startActivity(intent);
}
private void initializedata(){
jshared = getSharedPreferences("j", Activity.MODE_PRIVATE);
jshared2 = getSharedPreferences("j2", Activity.MODE_PRIVATE);
inop = findViewById(R.id.inop);
ans = findViewById(R.id.ans);
text = findViewById(R.id.text1);
}
private void logicg() {
String mount = jshared.getString("amount", "");
int amounts = Integer.parseInt(mount);
for (int i = 1; i < amounts; i++) {
//String shite = Integer.toString(qloop);
//Toast.makeText(getApplicationContext(), shite, Toast.LENGTH_SHORT).show();
if (i == amounts) {
Intent intent = new Intent(question.this, answerscrn.class);
startActivity(intent);
} else{
map = new HashMap<>();
map.put("answer", Objects.requireNonNull(ans.getText()).toString());
map.put("question", inop.getText().toString());
jshared2.edit().putString("data", new Gson().toJson(map)).commit();
}
}
}
}
</code></pre>
<p>I tried to do a <code>for loop + if else</code> inside the for loop and that only returns the error of <code>Condition 'i == amounts' is always 'false'</code> what i expect is for it to loop till it reaches the same number stated by the <code>amounts</code> (which is the user defined value) to open up a new page using intent.</p>

<p>I have an array of objects with some car data inside :</p>
<pre><code>const cars = [
{
"id": 1,
"car_make": "Lincoln",
"car_model": "Navigator",
"car_year": 2009,
"data": {
"rating": 4.9,
"engines": [3, 4, 5, 6]
}
},
{
"id": 2,
"car_make": "Mazda",
"car_model": "Miata MX-5",
"car_year": 2001,
"data": {
"rating": 4.1,
"engines": [1, 2]
}
},]
</code></pre>
<p>Next I need to sum all the engines numbers inside the data object in car: So I made the next function but everytime I try to console the array it remains unchanged.</p>
<pre><code>cars.forEach(car => {
car.data.engines.reduce((a,b) => a+b,0)
})
console.log(cars);
</code></pre>

<p>I want to loop through all objects(merge requests) in this JSON and create a new array with the merge_user.name.</p>
<pre><code>console.log(merge_requests[0].merge_user.name);
console.log(merge_requests[1].merge_user.name);
</code></pre>
<p>The logs above return both the correct values. However, I cannot loop through the JSON to create a new array from the data like this:</p>
<pre><code> const arrTest = [];
for(var i = 0; i < Object.keys(merge_requests).length; i++)
{
var mergeUserName = merge_requests[i].merge_user.name;
arrTest.push(mergeUserName);
}
console.log(arrTest);
}
</code></pre>
<p>The code above leads to the following error: <code>Uncaught (in promise) TypeError: resultData[i].merge_user is null</code></p>
<p>Here is a picture:
<a href="https://i.stack.imgur.com/p5SaZ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/p5SaZ.png" alt="enter image description here" /></a></p>
<p>I am currently learning JS coming from R. I have huge problems working with JSON instead of dataframes and I cannot find any documentation to learn from. I would appreciated any advice/ sources.</p>

<p>I wrote a code like this:</p>
<pre><code>Age: <input type="text" id="age">
</code></pre>
<p>And JavaScript:</p>
<pre><code><script>
function validateForm() {
let age = document.getElementById("age").value;
if (age) // is number?
}
</script>
</code></pre>
<p>I want the input to give an error if the value entered is a letter, I will only accept numbers. How can I tell if the entered value is not a number?</p>

<p>I have tried changing a bunch of things in the CSS with classes and id's, but nothing seems to make it so that both images will be on the far side of the screen (logo on the far left and profile on the far right).</p>
<p>Tried lots of different things like <code>text-align</code> and different <code>justify-contents</code> but nothing appears to work.</p>
<p>Here is the code:</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-css lang-css prettyprint-override"><code>.top-nav {

.top-nav div {

<p>I am calling rest api which expects nonce header. The nonce must be unique timestamp and every consecutive call should have <em>timestamp > previous one</em>. My goal is to launch 10 go routines and from each one do a call to the web api. Since we do not have control over the routine execution order we might end up doing a webapi call with a <em>nonce < previous one</em>. I do not have control over the api implementation.</p>
<p>I have stripped down my code to something very simple which illustrate the problem:</p>
<pre><code>package main
import (
"fmt"
"time"
)
func main() {
count := 10
results := make(chan string, count)
for i := 0; i < 10; i++ {
go someWork(results)
// Enabling the following line would give the
// expected outcome but does look like a hack to me.
// time.Sleep(time.Millisecond)
}
for i := 0; i < count; i++ {
fmt.Println(<-results)
}
}
func someWork(done chan string) {
// prepare http request, do http request, send to done chan the result
done <- time.Now().Format("15:04:05.00000")
}
</code></pre>
<p>From the output you can see how we have timestamps which are not chronologically ordered:</p>
<pre><code>13:18:26.98549
13:18:26.98560
13:18:26.98561
13:18:26.98553
13:18:26.98556
13:18:26.98556
13:18:26.98557
13:18:26.98558
13:18:26.98559
13:18:26.98555
</code></pre>
<p>What would be the idiomatic way to achieve the expected outcome without adding the <em>sleep</em> line?</p>
<p>Thanks!</p>

<p>I'm running Python 3.9.2 on a Raspberry Pi and I've written a script that will read water temperatures from my boiler and write them to a CSV file. However, each data item in the output file appears on a new line.</p>
<p>Here's my code:</p>
<pre><code>from subprocess import check_output
import csv
header = ['Flow', 'Return']
cmd = ["/usr/bin/ebusctl", "read", "-f"]
data = [
[float(check_output([*cmd, "FlowTemp", "temp"]))],
[float(check_output([*cmd, "ReturnTemp", "temp"]))]
]
with open('sandbox.csv', 'w', encoding='utf8', newline='') as f:
writer = csv.writer(f)
writer.writerow(header)
writer.writerows(data)
</code></pre>
<p>And here's the content of sandbox.csv:</p>
<pre class="lang-none prettyprint-override"><code>Flow,Return
57.19
43.12
</code></pre>
<p>How could I fix this?</p>

<p>I know there a bazillion question like this, but I couldn't find a good answer.
I'm compiling a source with preprocessor tokens defined in CFLAGS:</p>
<p>-D X=string1 -D Y=string2</p>
<p>I'm trying to create a string literal in my header file that combines these two values and use it in my sources like:</p>
<pre><code>printf("%s", COMBINED);
</code></pre>
<p>But this doesn't work:</p>
<pre><code> #define _COMBINED(x, y) x ## y
#define COMBINED _COMBINED(X, Y)
</code></pre>
<p>Thanks</p>

<p>I have a function below that returns a random INTERVAL between a range of hours, which appears to be working fine but is currently limited to hours only.</p>
<p>I would would like to expand this functionality to also support returning a random INTERVAL for days, minutes by passing in a literal (ie 'DAY', 'MINUTE' or 'SECOND')</p>
<p>For example if I call random_interval (1,4, 'DAY') I would get something like this +000000002 11:24:43.000000000 or if i call random_interval (20,40, 'MINUTE') I would get something like
+000000000 00:24:44.000000000</p>
<p>Thanks in advance to all who answer and for your time and expertise.</p>
<pre><code>
CREATE OR REPLACE FUNCTION random_interval(

<p>Hello I have a dataframe such as :</p>
<pre><code>Species COL1 COL2 COL3 COL4 COL5

SP2 1-2 2 0 1 0
SP3 0-1 1 2 0 1-2
</code></pre>
<p>and I would like to add new columns to count for each row the number of specific unique values such as :</p>
<pre><code>Species COL1 COL2 COL3 COL4 COL5 count_0 count_1-2 count_0-1-2 count_1 count_2
SP1 0 0 0 1-2 0-1-2 3 1 1 0 0
SP2 1-2 2 0 1 0 2 1 0 1 1
SP3 0-1 1 2 0 1-2 1 1 0 2 1
</code></pre>
<p>Does someone have na idea please ?</p>

<p>I'm trying to upload some files, but when I upload a file that already exists in the path, it overwrites the existing file. I'm trying to get the files renamed if a file with same name exists in the path, such that if file.pdf gets uploaded, it gets renamed file(1).pdf if there is an existing file that goes by file.pdf.</p>
<p><code>Code</code></p>
<pre><code>public async Task OnInputFile(InputFileChangeEventArgs e)
{
selectedFiles = e.GetMultipleFiles();
Message = $"{selectedFiles.Count} file(s) selected";
this.StateHasChanged();
foreach (var file in selectedFiles)
{
Stream stream = file.OpenReadStream(maxAllowedSize: 10_000_000);
var path = Path.Combine(Directory.GetCurrentDirectory(), "FilePath", file.Name);
FileStream fs = File.Create(path);
await stream.CopyToAsync(fs);
fs.Close();
stream.Close();
}
Message = $"{selectedFiles.Count} file(s) uploaded on server";
this.StateHasChanged();
}
</code></pre>
<p>Can anyone help me resolve this problem?</p>

<p>I got some error but I couldnt fix it. I want to add a new city with a country name but country id (if exists) will not change in database(it wont add with a new id).</p>
<p>Here is my City class;</p>
<pre><code> [Table("Cities")]
public class City
{
[Key]
public int Id { get; set; }
[Required]
[StringLength(30)]
public string Name { get; set; }
[ForeignKey("Countries")]
public int CountryId { get; set; }
public Country Country { get; set; }
}
</code></pre>
<p>And here is my Country class;</p>
<pre><code>[Table("Countries")]
public class Country
{
[Key]
public int Id { get; set; }
[Required]
[StringLength(30)]
public string Name { get; set; }
public ICollection<City> Cities { get; set; }
}
</code></pre>
<p>I used CQRS and Mediator design patterns.</p>
<p>This is my Create Command;</p>
<pre><code> public class CreateCityCommand : IRequest<City>
{
public City City { get; set; }
}
</code></pre>
<p>This is my Create Command Handler;</p>
<pre><code>public class CreateCityCommandHandler : IRequestHandler<CreateCityCommand, City>

public CreateCityCommandHandler(EssoContext context)
{
_context = context;
}
public async Task<City> Handle(CreateCityCommand request, CancellationToken cancellationToken)
{
var check = await _context.City.FirstOrDefaultAsync(c => c.Name == request.City.Name);
if (check != null)
{
throw new InvalidOperationException("You cannot add the same value!!!");
}
_context.City.Add(request.City);
await _context.SaveChangesAsync();
return request.City;
}
}
</code></pre>
<p>And here is my controller;</p>
<pre><code>[HttpPost("Create")]
public async Task<ActionResult<City>> PostCity([FromBody] City city)
{
try
{
var command = new CreateCityCommand() { City = city };
var result = await _mediator.Send(command);
return Ok(result);
}
catch(Exception ex)

}
}

<p><a href="https://i.stack.imgur.com/jDumY.jpg" rel="nofollow noreferrer">This is swagger output (seeing countries)</a></p>
<p>Every city has a country, and each country may have many cities. That's why i used CountryId and property (as FK) in City class. In country class, i defined collection(list) of cities. But I dont know what is the problem. Thanks for help...</p>

<p>I want to make a wavy text animation why when the script I made the animation doesn't run. I use mark aiming to mark 1 sentence, that's why I don't use span.</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>// Wrap every letter in a span

textWrapper2.innerHTML = textWrapper2.textContent.replace(/\S/g, "<mark class='letters2'>$&</mark>");

.timeline({
loop: true
})
.add({
targets: ".ml7 .letters2",
translateY: ["1.1em", 0],

<p>What I want to do is to create string stream , and output stream, giving the buffer of string stream to output stream, so that it will output data to the string stream. Everything seems fine, but when I try to add data to buffer of the string stream it overrides the previous data. My question is why? and how can achieve a result, such that it does not override but simply adds to the string stream. Here is my code below:</p>
<pre><code>#include <iostream>
#include <iomanip>
#include <string>
#include <sstream>
using namespace std;
int main ()
{
stringstream s1("hello I am string stream");
streambuf *s1_bfr = s1.rdbuf();
ostream my_stream (s1_bfr);
my_stream <<"hey"<<endl;
cout <<s1.rdbuf()<<endl; //gives the result : " hey o I am string stream"( seems to me overriden)
return 0;
}
</code></pre>

<p>I would like to count the number of color changes in a network using a function.</p>
<p>A change would be <code>"red"</code> to <code>"green"</code> (from <code>a</code> to <code>b</code> in the example)</p>
<p>Overlaps (e.g., <code>"green"</code> to <code>"green"</code> and <code>"orange"</code>, from <code>c</code> to <code>c1</code> in the example) should not count as a change.</p>
<p>Example data:</p>
<pre><code>library(tidyverse)
network <- tibble(
from=c("a","b","c","c"),
to= c("b","c","c1","c2"))
colors <- list(
a=list("red"),
b=list("red"),
c=list("green"),
c1=list("green","orange"),
c2=list("blue","black")
)
</code></pre>
<p>The correct output of the function would be 2 (from <code>b</code> to <code>c</code> and <code>c</code> to <code>c2</code>) in this example.</p>

<p>I have a MSSQL database table <code>Events</code>. I am worried that performance could be improved.</p>
<pre><code>EventId LocationId Start End Quantity Price Currency
1 4 2022-08-31 22:00:00.0000000 +02:00 2022-08-31 23:00:00.0000000 +02:00 7.50000 2.0 EUR
2 2 2022-04-04 19:00:00.0000000 +01:00 2022-04-04 20:00:00.0000000 +01:00 1.50000 7.5 EUR
3 2 2022-04-04 19:00:00.0000000 +01:00 2022-04-04 20:00:00.0000000 +01:00 4.00000 8.2 EUR
</code></pre>
<p>I already have the following index:</p>
<pre><code>CREATE NONCLUSTERED INDEX [IDX__Events__Location_Start_End] on [Events]
(
[LocationId] asc,
[Start] asc,
[End] asc
)
</code></pre>
<p>But Azure suggests that I create this index (medium impact):</p>
<pre><code>CREATE NONCLUSTERED INDEX [IDX__Events__Location_End] ON [dbo].[Events] ([LocationId], [End]) INCLUDE ([Currency], [Price], [Quantity], [Start]) WITH (ONLINE = ON)
</code></pre>
<p>Hint: I do a lot of queries where I select Events greater than a start time and less than an end time.</p>
<p>Why is this extra index useful? Should I change my first index instead?</p>
<p><strong>EDIT</strong>:</p>
<p>I run this code (EF Core) very often:</p>
<pre><code>var relevantEvents = await _events.Where($@"
[{nameof(Events.LocationId)}] = @locationId
and [{nameof(Events.End)}] > @start
and [{nameof(Events.Start)}] < @end
", args);
</code></pre>
<p>Besides that, I upsert to the table often as well.</p>

<p>Probably a dumb question but I'm using toTimestamp(now()) to retrieve the timestamp. Is there any way to offset the now() by my specified timeframe.</p>
<p>What I have now:</p>
<pre><code>> print(session.execute('SELECT toTimestamp(now()) FROM system.local').one())
2022-12-04 12:12:47.011000
</code></pre>
<p>My goal:</p>
<pre><code>> print(session.execute('SELECT toTimestamp(now() - 1h) FROM system.local').one())
2022-12-04 11:12:47.011000

<p>Update, I have created a signal file like this, so for example if an employer has created a shift, the admin will get an email notification like this:</p>
<pre><code>from django.db.models.signals import post_save
from django.dispatch import receiver
from .models import Shift
from django.core.mail import send_mail
@receiver(post_save, sender=Shift)
def send_mail_to_user(sender, instance, created, **kwargs):
if created:
send_mail(
'A new shift has been created by employer xxx',
'Here is the message.',
'from@example.com',
['to@example.com'],
fail_silently=False,
)
</code></pre>
<p>Original post:</p>
<p>Hi, I 'm trying to add signals when an employer or admin/staff has created a shift. Currently I have a view like this, I 'm wondering how should I modify it so I can have a post-save signal?</p>
<pre><code>@login_required
@admin_staff_employer_required
def createShift(request):
user=request.user
employer=Employer.objects.all()
form = CreateShiftForm()
if request.method == 'POST':
form = CreateShiftForm(request.POST)
if form.is_valid():
form.save()
messages.success(request, "The shift has been created")
return redirect('/shifts')
else:
messages.error(request,"Please correct your input field and try again")
context = {'form':form}
return render(request, 'create_shift.html', context)
</code></pre>
<p>Thanks for your help!</p>

<p>I'm currently training on codewars, and today was multiples of 3 and 5.
I tried with a casual solution using reduce + ternary, and it worked.</p>
<p>I then tried to solve it with recusrive function.
Instructions are as follow :</p>
<p>If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.</p>
<p>Finish the solution so that it returns the sum of all the multiples of 3 or 5 below the number passed in. Additionally, if the number is negative, return 0 (for languages that do have them).</p>
<p>Link is here</p>
<p><a href="https://www.codewars.com/kata/514b92a657cdc65150000006" rel="nofollow noreferrer">https://www.codewars.com/kata/514b92a657cdc65150000006</a></p>
<p>Here is my solution :</p>
<pre><code>let res = 0
function solution(n){
if(n - 1 <= 0) {
return 0
}
if((n - 1) % 3 > 0) {
if((n - 1) % 5 > 0) {
return solution(n - 1, res)
} else {
res += n - 1
solution(n - 1, res)
}
} else {
res += n - 1
solution(n - 1, res)
}
return res
}
</code></pre>
<p>It works on my computer but fails on codewars attemps, giving extravagant results, such as solution(6) = 9283 whereas on my computer 8 (correct answer)</p>
<p>Also, I got the maximum call stack exceeded on codewars for 9513, but not on my computer.</p>
<p>Ideas anyone ?</p>

<p>This is the code I came up with so far. The goal is to generate a table 10x10 just like in the image <a href="https://i.stack.imgur.com/7yQ4s.jpg" rel="nofollow noreferrer">what i need</a></p>
<p>The problem that I can't seem to understand is why it doesn't generate zeros and the last number 27 and just throws everything together.</p>
<pre class="lang-java prettyprint-override"><code>public class Main {
public static void main(String[] args) {
int values[][] = new int[10][10];
int n = 1;
for (int i=0; i<=9; i++) {
for (int j=9-i; j>=7-i; j--){
if (j >=0){
values[i][j] = n++;
}
System.out.printf(values[i][j] + " ");
}
System.out.println();
}
}
}
</code></pre>
<p>I would appreciate any suggestions, thanks!</p>
<p>What is see/get -- > <a href="https://i.stack.imgur.com/WxvrK.jpg" rel="nofollow noreferrer">what i see/ error</a></p>

<p>I have the following code</p>
<pre class="lang-py prettyprint-override"><code>(Pdb) set(range(2, 2)).issubset(set(range(10, 95)))
True
</code></pre>
<p>and I don't understand why it's returning <code>True</code>. <code>issubset</code> is supposed to check if a set contains all the items of another set, but <code>2</code> can't be contained in a range from <code>10</code> to <code>95</code>.</p>
<p>Am I misunderstanding Python's doc? Or is that a bug?</p>

<p>I am trying to set the <code>defaultValue</code> for on the <code><Select /></code> component from react-select package.</p>
<p>However, when I do set the default value, using a react hook (useState), it does not render the default values.</p>
<p>If I was to hard code the array, it renders he default values fine.</p>
<p><strong>What I have so far</strong></p>
<p><a href="https://codesandbox.io/s/codesandboxer-example-forked-2e3unk?file=/example.tsx:0-608" rel="nofollow noreferrer">https://codesandbox.io/s/codesandboxer-example-forked-2e3unk?file=/example.tsx:0-608</a></p>
<pre><code>import React, { useEffect, useState } from "react";
import Select from "react-select";
export default function AnimatedMulti() {
const [values, setValues] = useState([]);
const [defaultValues, setDefaultValues] = useState([]);
useEffect(() => {
const data = [
{ value: 1, label: "Label 1" },
{ value: 2, label: "Label 2" },
{ value: 3, label: "Label 3" }
];
setValues(data);
setDefaultValues([data[0], data[1]]);
}, []);
return (
<Select

<p><a href="https://i.stack.imgur.com/bMbmv.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bMbmv.png" alt="enter image description here" /></a></p>
<p><strong>Expectation</strong></p>
<p>I am expecting the select component to render <strong>two</strong> default values, however nothing has been rendered.</p>
<p><strong>Question</strong></p>
<p>How can I load the default values using react hook <code>useState</code>?</p>

<p>I need to check if 24 hours have passed between two dates. If 24 hours have passed, I will update the data in my room database, if not, I will not. How can I do that. I thought about keeping a date with shared preferences and comparing that date with the current date, but I don't know how to do that.</p>

<p>I have 2 scripts one on player :</p>
<pre><code>using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerPositionCorrection : MonoBehaviour
{
Transform _playerTransform;
public float _xAxys;
public float _newXAxys;
public GameObject _changerPlayerPosition;
private void Start()
{
_playerTransform = GetComponent<Transform>();
}
private void OnTriggerEnter(Collider other)
{
if (other.tag == "ChangePlayerPosition")
{
float _newXAxys = this.GetComponent<ChangePositionOn>()._newPostion;
}
}
private void LateUpdate()
{
if (transform.position.z != 0)
{
transform.position = new Vector3(_xAxys, _playerTransform.position.y, _playerTransform.position.z);
}
}
</code></pre>
<p>and second on object :</p>
<pre><code>public class ChangePositionOn : MonoBehaviour
{
public float _newPostion = 5;
void Start()
{
}
// Update is called once per frame
void Update()
{
}
}
</code></pre>
<p>I using Unity 2022.1.19f1 and C#.</p>
<p>Thank you for your healp,
Michal</p>
<p>I would like to have several object in my game and when player will collide with them change location on x axis.</p>
<p>Unfortunately every time i have this error message:</p>
<pre><code>NullReferenceException: Object reference not set to an instance of an object
PlayerPositionCorrection.OnTriggerEnter (UnityEngine.Collider other) (at Assets/Scripts/PlayerPositionCorrection.cs:23)
</code></pre>

<p>Below is the problem I found on the internet.</p>
<pre><code>int main()
{
int a[4] = { 10, 21, 32, 43};
int *p = a + 3;
++*--p;
++*p--;
p[2] += p[1];
for (int i = 0; i < 4; ++i)
printf("%d - %d\t", a[i]);
return 0;
}
</code></pre>
<p>//What will be the output?</p>
<p>answer : 10 21 34 77</p>
<p>I understood a lot of things, but the only thing I'm stuck on:</p>
<p>What is the difference between <code>(++*--p)</code> and <code>(++*p--)</code> ?</p>
<p>Shouldn't these two give the same result? Because <code>(*p--)</code> and <code>(*--p)</code> give the same result in the compiler. The compiler I use is Code::Blocks</p>
