74,252,049 | <p>I am trying to run a Fyne app on a VM. I have attempted it on VirtualBox and Azure. After running the app, I get the following error:</p>
<pre><code> Cause:APIUnavailable: WGL: The driver does not appear to support OpenGL
At: fyne.io/fyne/v2@v2.2.3/internal/driver/glfw/driver.go:148
</code></pre>
<p><a href="https://i.stack.imgur.com/tAKRY.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/tAKRY.png" alt="enter image description here" /></a></p>
<p>I was able to solve this in VM by enabling <strong>3D acceleration</strong>. But I am not able to do the same in Azure.</p>
<p><a href="https://i.stack.imgur.com/4PSgp.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4PSgp.png" alt="enter image description here" /></a></p>
<p>One option is to select the template which supports GPU. There are special VM series like the N-series VMs which support GPU. But just to run a Fyne app, I don't want to pay for a GPU VM.</p>
<p>Another option is to use the GPU pass-through feature. But I am not able to find any documentation on how to do this.</p>
<p>Is there any other way to solve this?</p>

74,252,061 | <p>I have a problem with some Android Phone with an error :
java.io.FileNotFoundException: /storage/emulated/0/Download/Joueurs.xlsx: open failed: EACCES (Permission denied)
I looked at solutions given by Stackoverflow. I changed my code and manifest but always had the same error. We have a problem with a Galaxy S21. In the parameter of it, it's not possible to change the permission setting to change the multimédia file to all files.
It seems difficult to test this problem with the simulator<br />
Have you an idea to solve this error
Thank you very much for your help</p>
<p>Best regards</p>
<p>Georges</p>

74,252,124 | <p>I'm creating a library app where users input data into a <code>form</code> and the values they enter are displayed in its own <code>div</code>.</p>
<p>I have this <code>array</code></p>
<pre><code>let myLibrary = [
{
title: "The Once and Future King",
author: "White",
pages: 654,
},
{
title: "The Hobbit",
author: "Tolkien",
pages: 304,
},
];
</code></pre>
<p>which is automatically displaying each <code>object</code> (for testing purposes) on my page thanks to this <code>forEach()</code></p>
<pre><code>myLibrary.forEach((book) => {
const bookContent = document.getElementById("content");
const addBook = document.createElement("div");
addBook.className = "book";
bookContent.appendChild(addBook);
addBook.innerHTML = `
<div class="title">
<p class="bookTitle">
<span>${book.title}</span>
</p>
</div>
<div class="body">
<p>
Author: <span>${book.author}</span>
</p>
<p>
Pages: <span>${book.pages}</span>
</p>
</div>`;
});
</code></pre>
<p>The <code>forEach</code> makes it so every <code>object</code> inside my <code>array</code> is displayed in its own 280x365 pixel <code>div</code> and the book title, author and page count is displayed in it's own <code>p</code> element. I'm also using <code>flex</code> for organization.</p>
<p>I also have a <code>form</code> which users can input a new book title, author and page number to add to their growing book collection.</p>
<pre><code>const form = document.getElementById("form");
form.addEventListener("submit", updateLibrary);
function updateLibrary(event) {
event.preventDefault();
const title = document.getElementById("title").value;
const author = document.getElementById("author").value;
const pages = document.getElementById("pages").value;
const book = {
title: title,
author: author,
pages: parseInt(pages),
};
myLibrary.push(book);
console.log(myLibrary);
}
</code></pre>
<p>When I fill the form out, everything appears to work perfectly. I have <code>console.log</code> in my <code>updateLibrary</code> function and I notice the <code>object</code> is being pushed into the <code>array</code> like I want it to. But every time I hit the <code>submit</code> button, a new <code>div</code> isn't being created for the new book. I'm guessing this has to do with my <code>forEach</code> not triggering the new <code>object</code> but I can't find a way to fix this.</p>
<p>How can I better write my code so a new <code>div</code> is also being created with the new <code>object</code> every time I submit the <code>form</code>?</p>
<p><em>What I've tried</em></p>
<p>I've tried rearranging my code so the <code>forEach</code> is below the <code>array</code>, so the <code>updateLibrary</code> function is above and below the <code>forEach</code>.</p>
<p>I've also tried putting the <code>forEach</code> inside the <code>updateLibrary</code> function. That did make it work but it gave me an even worse bug.</p>

74,252,237 | <p>We have a table having around 10 million records and we are trying to update some columns using the id(primary key) in the where clause.</p>
<pre><code>UPDATE table_name SET column1=1, column2=0,column3='2022-10-30' WHERE id IN(1,2,3,4,5,6,7,......etc);
</code></pre>
<p>Scenario 1: when there are 3000 or fewer ids in the IN clause and if I try for EXPLAIN, then the 'possible_keys' and 'key' show the PRIMARY, and the query gets executed very fast.</p>
<p>Scenario 2: when there are 3000 or more ids(up to 30K) in the IN clause and if I try for EXPLAIN, then the 'possible_keys' shows NULL and the 'key' shows the PRIMARY and the query runs forever. If I use FORCE INDEX(PRIMARY) then the 'possible_keys' and the 'key' shows the PRIMARY and the query gets executed very fast.</p>
<p>Scenario 3: when there are more than 30k ids in the IN clause and even if I use FORCE INDEX(PRIMARY), the 'possible_keys' shows NULL, and the 'key' shows the PRIMARY and the query runs forever.</p>
<p>I believe the optimizer is going for a full table scan instead of an index scan. Can we make any change such that the optimizer goes for an index scan instead of a table scan? Please suggest if there are any parameter changes required to overcome this issue.</p>

74,252,277 | <p>Assuming I have the following module <strong>signature</strong> and <strong>implementation</strong> in the same file named <code>monoids.ml</code>:</p>
<pre class="lang-ml prettyprint-override"><code>module type MonoidADT = sig
type 'a monoid
(* . . . *)
end
module Monoid : MonoidADT = struct
type 'a monoid = Monoid of ('a list) * ('a -> 'a -> 'a) * ('a)
(* . . . *)
end
</code></pre>
<p>How am I supposed to use a constructor, of the type defined in the implementation, in an other file (module)? Is it directly accesible or should I create something like a factory function with <code>'a monoid</code> as return type?</p>
<p>What I tried to do is simply open the module and call its constructor as I would do inside the module, but of course it doesn't work and gives me <code>Unbound constructor Monoid</code> error:</p>
<pre class="lang-ml prettyprint-override"><code>open Monoids.Monoid;;
let boolean_monoid = Monoid ([true; false], ( || ), false);;

74,252,349 | <p>I am fairly new to programming, so I hope you can help me.</p>
<p>I want to check if a input string is a palindrome. The palindrome-checker is case-insensitive.</p>
<p>Here is what I got so far:</p>
<pre><code># input word
word = input("Enter a word: ")
# make it case-INsensitive
word = word.lower()
# we also need the length of word to iterate over its range
length_word = int(len(word))
### use a for-loop
for letter in range(len(word)):
if word[-length_word] == word[-1]:
print(word, "is a palindrome.")
# if it doesn't match, its not a palindrome, print message
else:
print(word, "is not a palindrome.")
</code></pre>
<p>What bothers me is that it prints the phrase "is a palindrome." everytime. How can I fix it so it will only print it once if the word is a palindrome?</p>
<p>Thank you so much in advance!</p>

<p>this is the controller im using to pass the json to model class</p>
<pre><code>class user_controller extends GetxController {

Future<void> getUserData() async {

userList.add(User.fromJson(response.body));
} else {}
}
}
</code></pre>
<p>but I pass the response like this it generates an error</p>
<p>List' is not a subtype of type 'Map<String, dynamic>'</p>
<p>I change the class like this<code> User.fromJson(List<dynamic> json)</code> like that way I can pass the data like this <code>id =json[0]["id"] </code></p>
<p>but it only pass the id of first element of the list</p>
<p>How Can I pass all the data? this list has 5 map object I want to display all this data on a listview using this model</p>

74,252,418 | <p>I use this regex to mark whole sentences ending in period, question mark or exclamation mark - it works so far.</p>
<pre><code>[A-Z][^.!?]*[.?!]
</code></pre>
<p>But there are two problems:</p>
<ol>
<li>if there is a number followed by a period in the sentence.</li>
<li>if there is an abbreviation with a period in the sentence.</li>
</ol>
<p>Then the sentence is extracted incorrectly.
Example:</p>
<blockquote>
<ol>
<li>Sentence Example: "Er kam am 1. November."</li>
</ol>
</blockquote>
<blockquote>
<ol start="2">
<li>Sentence Example: "Dr. Schiwago."</li>
</ol>
</blockquote>
<p>The first sentence then becomes two sentences because a period follows the number.
The second sentence then also becomes two sentences because the abbreviation ends in a period.</p>
<p>How can I adjust the regex so that both problems do not occur?</p>
<p>So in the first sentence, whenever a period follows a number, this should not be seen as the end of the sentence, but the regex continues to the next period.</p>
<p>In the second sentence, for example, a minimum size of 4 characters would ensure that the abbreviation is not seen as a complete sentence.</p>

<p>I know there are a lot of pragmatic ways to achieve this. But I want to know, specifically, why this won't work. This piece of code</p>
<pre class="lang-cs prettyprint-override"><code> messageStore?.Clear();
foreach (var x in Errors.Errors)

FieldIdentifier f = new FieldIdentifier(cmd, x.Identifier);
messageStore.Add(f, x.ErrorMessage);
}
editContext.NotifyValidationStateChanged();
</code></pre>
<p>works all the time in other EditForms.</p>
<p>UPDATE: There was a typo in the code. It's been deleted(Errors=new())</p>
<p>ValidationSummary works</p>
<p>I've tried with a variable so the lambda won't capture i. It makes no difference</p>
<pre class="lang-cs prettyprint-override"><code>for (int i = 0; i < Errors.Rows; i++)
{
var j=i;
<ValidationMessage For="()=>cmd.Users[j].Name" />
}

74,252,503 | <p>I want to change an image when the user hovers over a certain text. I found this question on stackoverflow (<a href="https://stackoverflow.com/questions/28398273/change-image-on-hover-javascript">Change Image On Hover Javascript</a>), but here the image is changed when the user hovers the image not the text. So I tried to adapt the code of the answer, so that the image is cahnged on texthover (I just put the "onmouseover" and "onmouseout" into the h1 instead of the img).</p>
<p>This is the code of the answer which changes the image when the user hovers the image:</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><img
onmouseover="this.src='images/Logo white transparent.png'"
onmouseout="this.src='images/Logo black transparent.png'"
height="100px"
src="images/Logo black transparent.png"
/></code></pre>
</div>
</div>
</p>
<p>And this is the code I tried in order to change the image when the text is hovered:</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><img

</code></pre>
<p>In my global git config I did not add any user/email config.</p>
<p>Each repository contains the correct user and email.</p>
<p>When I try to push, it says that <code>first-user</code> doesn't have permission.</p>
<pre><code>ERROR: Permission to user/repo.git denied to first-user.
fatal: Could not read from remote repository.
</code></pre>
<p>I believe to have read somewhere that git uses the ssh key it sees, so maybe it is seeing the first key and taking that.</p>
<p>Doing <code>git config --list --show-origin --show-scope</code> in the repo folder, I get:</p>
<pre><code>global file:/home/user/.gitconfig core.autocrlf=input
local file:.git/config user.name=Second
local file:.git/config user.email=mail@second.com
</code></pre>
<p>Nowhere is there any setup for the first user.</p>
<p>Doing <code>git remote -v</code> returns:</p>
<pre><code>origin git@github.com-second-user:user/repo.git (fetch)
origin git@github.com-second-user:user/repo.git (push)
</code></pre>
<p><strong>Relevant note:</strong></p>
<p>Doing <code>ssh -T github.com-second-user</code> returns <em>Hi <strong>first-user</strong>!, You've successfully authenticated...</em></p>
<p><strong>Note</strong>: this error happens both using the git cli, and also using git via the phpStorm UI.</p>
<p>How can I force it to use the second key for the second user?</p>
<p>Thanks!</p>

74,252,521 | <p>I'm using Springboot and JPA to create two tables sharing the same primary key.</p>
<p>For the first table I write:</p>
<pre><code>public class UserAccount implements Serializable
{
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@OneToOne(mappedBy ="user", cascade = {CascadeType.REMOVE, CascadeType.MERGE,
CascadeType.REFRESH}, fetch=FetchType.LAZY)
@PrimaryKeyJoinColumn
private UserLogin login;
}
</code></pre>
<p>For the second table I write:</p>
<pre><code>public class UserLogin implements Serializable
{
@Id
private Long user_id;
@OneToOne(cascade = {CascadeType.MERGE, CascadeType.REFRESH},
fetch=FetchType.LAZY)
@MapsId("user_id")
@JoinColumn(name = "user_id", referencedColumnName = "id")
@Setter(AccessLevel.NONE)
private UserAccount user;
public void setUser(UserAccount user)
{
this.user = user;
this.user_id = user.getId();
}
}
</code></pre>
<p>Other stuff are omitted for conciseness. The code works because I manually set the id of UserLogin by writing the statement</p>
<pre><code>this.user_id = user.getId();
</code></pre>
<p>otherwise I get the error:</p>
<blockquote>
<p>Hibernate error: ids for this class must be manually assigned before calling save():</p>
</blockquote>
<p>I guess that the ids can be manually managed but I cannot get the right configuration.</p>
<p>UPDATE:
I found the solution thanks (see the accepted answer). Now I just would get rid of the findById() when setting the user login.</p>
<pre><code>//these methods are defined within a dedicated @Service
@Transactional
public void createLoginInfo(UserAccount user)
{
UserLogin userlogin=new UserLogin();
this.addLoginToUser(userlogin,user);
loginService.save(userlogin);
}
@Transactional
public void addLoginToUser(UserLogin login, UserAccount account)
{
//whit this commented line works
//UserAccount acc= this.findById(account.getId());
login.setUser(account);
account.setLogin(login);
}
//In a transactional test method I first create the user then I call
userService.save(theuser);
userService.createLoginInfo(theuser);

74,252,524 | <p>I have created an ASP.NET Core Web API app that connects to a SQL Server database. I have a table in which I need to use SQL Server always encryption.</p>
<p>I'm creating a column master key with the following T-SQL:</p>
<pre><code> CREATE COLUMN MASTER KEY [MyCMK]
WITH
(
KEY_STORE_PROVIDER_NAME = N'MSSQL_CERTIFICATE_STORE',
KEY_PATH = N'CurrentUser/my/2DB1E2F1BE5E2A640FB1626895DB174D1A3176DD'
);
</code></pre>
<p>and then a column encryption key using this column master key as follows:</p>
<pre><code> CREATE COLUMN ENCRYPTION KEY [MyCEK]
WITH VALUES
(
COLUMN_MASTER_KEY = [MyCMK],
ALGORITHM = 'RSA_OAEP',
ENCRYPTED_VALUE = 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
);
</code></pre>
<p>Then I create my table using TSQL which has 2 encrypted columns:</p>
<pre><code>CREATE TABLE [Appraisal].[Answer]
(
[Id] [uniqueidentifier] NOT NULL,
[AppraisalId] [uniqueidentifier] NOT NULL,
[QuestionId] [uniqueidentifier] NOT NULL,
[AppraiserId] [uniqueidentifier] NOT NULL,
[AppraisedId] [uniqueidentifier] NOT NULL,
[InteractionGroupId] [uniqueidentifier] NOT NULL,
[Point] [int] ENCRYPTED WITH (
COLUMN_ENCRYPTION_KEY = MyCEK,
ENCRYPTION_TYPE = RANDOMIZED,
ALGORITHM = 'AEAD_AES_256_CBC_HMAC_SHA_256'),
[Comment] [nvarchar](1024) COLLATE Latin1_General_BIN2 ENCRYPTED WITH (COLUMN_ENCRYPTION_KEY = MyCEK,
ENCRYPTION_TYPE = DETERMINISTIC,
ALGORITHM = 'AEAD_AES_256_CBC_HMAC_SHA_256'),
[CreateDateTime] [datetime] NOT NULL
)
</code></pre>
<p>Then in order to install my certificate on any machine which will host my app I export SQL Server Always Encrypted certificate using windows certification manager to my application root folder and try to install it using this code:</p>
<pre><code>X509Certificate2 cert = new X509Certificate2("MyExportedCertificate.pfx", "MyPassword",
X509KeyStorageFlags.Exportable | X509KeyStorageFlags.PersistKeySet);
X509Store store = new X509Store(StoreName.My);
</code></pre>
<p>I run the app and everything works fine. the X509Certificate2 class installs my certificate and my app can encrypt/decrypt the data.</p>
<p>then I create a docker file using Visual Studio> Add Item> Docker Support and add this line of code to copy my "*.pfx" file to my app's root folder:</p>
<pre><code>FROM mcr.microsoft.com/dotnet/aspnet:6.0-alpine3.16-amd64 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443
COPY ["Api/MyExportedCertificate.pfx", ""]
</code></pre>
<ul>
<li>rest of the docker file contents are omitted for clarity.</li>
</ul>
<p>then I edit my docker-compose file to add my sql server image:</p>
<pre><code>services:
api:
image: ali-api
container_name: web_api_application
ports:
- "5000:80"
environment:
- ASPNETCORE_ENVIRONMENT=Production
sqldb:
image: mcr.microsoft.com/mssql/server:2019-latest
environment:
- SA_PASSWORD=Qwerty*2607548
- ACCEPT_EULA=Y
ports:
- "1440:1433"
container_name: sqldb
</code></pre>
<p>and finally I build my app:</p>
<pre><code>docker build -t ali-api -f Api/Dockerfile .
docker-compose up
</code></pre>
<p>my app starts working and I can access my swagger page.</p>
<p><a href="https://i.stack.imgur.com/RwLPx.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RwLPx.png" alt="enter image description here" /></a></p>
<p>I can see that CMK and CEK are both generated too.</p>
<p><a href="https://i.stack.imgur.com/fN3Wk.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/fN3Wk.png" alt="enter image description here" /></a></p>
<p>And also my always encryption is done as well:</p>
<p><a href="https://i.stack.imgur.com/wFyIk.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wFyIk.png" alt="enter image description here" /></a></p>
<p>But it seems that my license is not installed, because when I want to insert a data to my encrypted table columns I get the error:</p>
<blockquote>
<p>An error occurred while saving the entity changes. See the inner exception for details. Failed to decrypt a column encryption key using key store provider: 'MSSQL_CERTIFICATE_STORE'. The last 10 bytes of the encrypted column encryption key are: '51-29-CD-17-1C-E2-6E-13-A4-45'. Operation is not supported on this platform.</p>
</blockquote>
<p>what am I doing wrong?</p>
<p>how can I import this certificate in linux?(docker)</p>
<p>how can I install this certificate in linux?(docker)</p>
<p>.pfx file is located in my app's root folder. how can I install this .pfx file in linux?</p>
<p><a href="https://i.stack.imgur.com/duds9.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/duds9.png" alt="enter image description here" /></a></p>

<pre><code>df = pd.DataFrame([["a", "b", "c"], ["d", "e", "f"],["g", "h", "i"]])
</code></pre>
<p>How do I get the column index of "c" in row 0?</p>
<p>I know there are ways to get the column index if there are column labels, but I can't find ways to return the column index just based on the cell value, if searching a particular row.</p>

74,252,598 | <p>I'm trying to make a page with a horizontal scrolled image gallery using flex grid.</p>
<p>The gallery should be centered on the page with bars on the sides. To accomplish this, I have created a css grid with areas <code>'mainleft maincenter mainright'</code>. It shuld look something like this:
<a href="https://i.stack.imgur.com/Xt0K3.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Xt0K3.png" alt="Horizontal image gallery" /></a></p>
<p>The problem is the page is not responsive. So, if I do not set <code>max-width</code> of the gallery the site looks like this:
<a href="https://i.stack.imgur.com/Gws3Y.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Gws3Y.png" alt="Horizontal image gallery" /></a></p>
<p>The gallery overflows the entire page. Setting <code>max-width</code> to 100% do not work. Setting <code>max-widt</code> to something like 700px works but then the page is not responsive anymore.</p>
<p>Code for the page:</p>
<pre><code><!DOCTYPE html>

74,252,649 | <p>I'm really new to the world of python, and especially dictionaries, so it is very likely that the answer to my question is quite simple, but I really can't figure it out...</p>
<p>My problem is, that I can't seem to figure out how to access one specific list element at a certain position when I have a dictionary that has a list as it's values.</p>
<p>More specifically I have the following list:</p>
<pre><code>my_books = {'Eragon': [2007,'Paolin'], 'Harry Potter': [1992,'Rowling'], 'Obscura': [2017, 'Canon'], 'Many Wonders': [1964,'Meyers'], 'Never': [2001, 'McKey']}
</code></pre>
<p>What I now want to achieve is that it returns me the value at list position 1 and the title of the book (the key) in a very simple, alphabetically sorted table.</p>
<p>Output required:</p>
<pre><code>Canon Obscura
McKey Never
Meyers Many Wonders
Paolin Eragon
Rowling Harry Potter
</code></pre>
<p>What I can't seem to figure out is how to only print the list element at position 1, instead of the whole list.</p>
<p>My code:</p>
<pre><code>for book in my_books:
print(my_books[book], ' ', book)
</code></pre>
<p>My output:</p>
<pre><code>[2007,'Paolin'] Eragon
[1992,'Rowling'] Harry Potter
[2017, 'Canon'] Obscura
[1964,'Meyers'] Many Wonders
[2001, 'McKey'] Never
</code></pre>
<p>Anyways, if any one of you could help me out here I would greatly appreciate it!</p>

74,252,668 | <p>currently I'm trying the following setup:</p>
<p>I have:</p>
<ul>
<li>one cluster</li>
<li>one Ingress Controller</li>
<li>one url (myapp.onazure.com)</li>
<li>two namespaces for two applications default and default-test</li>
<li>two deployments, ingress objects, services for the namespaces</li>
</ul>
<p>I can easily reach my app from the default namespace with path based routing '/' as a prefix rule
Now i have tried to configure the second namespace and following rule: /testing to hit another service</p>
<p>Unfortunately i get an HTTP404 when i try to hit the following URL myapp.onazure.com/testing/openapi.json</p>
<p>What did I miss?</p>

<p>Maybe I am missing a rewrite target to simply '/' in the testing namespace ingress?</p>

74,252,691 | <p>I am trying to implement an interface of the shape of</p>
<pre><code>type someUnion = "foo" | "bar";
interface RecursiveInterface {
a: number;
b: Array<number>;
[key in someUnion]?: RecursiveInterface;
}

<p>to describe objects like</p>
<pre><code>const someObject: RecursiveInterface = {

foo: {
a: 0,
b: [2,6],
bar: {
a: 8,
b: 7

</code></pre>
<p>However this leads to the error <code>A mapped type may not declare properties or methods.</code></p>
<p>Suggesting that the following is viable</p>
<pre><code>type mappedType = {
[key in someUnion]?: RecursiveInterface;
}
</code></pre>
<p>which throws no errors, but as the initial error suggests, does not allow additional properties.</p>
<p>Extending the initial interface with the mappedType appears to work though, as in</p>
<pre><code>interface RecursiveInterface extends mappedType {
a: number;
b: Array<number>
}
</code></pre>
<p>Now my question is, <strong>is this the correct way to define the desired interface or is there a more concise option, that does not require extending the interface with an additional mapped type?</strong></p>

74,252,734 | <p>I'm trying to make an automation program to scrape part of a website. But this website is made out of javascript, and the part of the website I want to scrape is in a shadow dom.</p>
<p>So I figured out that I should use selenium to go to that website and use this code to access elements in shadow dom</p>
<pre><code>def expand_shadow_element(element):
shadow_root = driver.execute_script('return arguments[0].shadowRoot', element)
return shadow_root
</code></pre>
<p>and use</p>
<pre><code>driver.page_source
</code></pre>
<p>to get the HTML of that website. But this code doesn't show me elements that are inside the shadow dom.</p>
<p>I've tried combining those two and tried</p>
<pre><code>root1 = driver.find_element(By. CSS_SELECTOR, "path1")
shadow_root = expand_shadow_element(root1)
html = shadow_root.page_source
</code></pre>
<p>but I got</p>
<pre><code>AttributeError: 'ShadowRoot' object has no attribute 'page_source'
</code></pre>
<p>for a response. So I think that I need to use BeautifulSoup to scrape data from that page, but I can't figure out how to combine BeautifulSoup and Selenium to scrape data from a shadow dom.</p>
<hr/>
<p>P.S. If the part I want to scrape is</p>
<pre><code><h3>apple</h3>
<p>1$</p>
<p>red</p>
</code></pre>
<p>I want to scrape that code exactly, not</p>
<pre><code>apple
1$
red
</code></pre>

74,252,737 | <p>I have a database of a the employees of a company that looks like this:</p>
<pre><code>{
_id: 7698,
name: 'Blake',
job: 'manager',
manager: 7839,
hired: ISODate("1981-05-01T00:00:00.000Z"),
salary: 2850,
department: {name: 'Sales', location: 'Chicago'},
missions: [
{company: 'Mac Donald', location: 'Chicago'},
{company: 'IBM', location: 'Chicago'}
]
}
</code></pre>
<p>I have an exercise in which I need to write the MongoDb command that returns all them employees who did all their missions in Chicago. I struggle with the all because I cannot find a way to check that all the locations of the missions array are equal to 'Chicago'.</p>
<p>I was thinking about doing it in two time: first find the total number of missions the employee has and then compare it to the number of mission he has in Chicago (that how I would do in SQL I guess). But I cannot found the number of mission the employee did in Chicago. Here is what I tried:</p>
<pre><code>db.employees.aggregate([
{
$match: { "missions": { $exists: true } }
},
{
$project: {
name: 1,
nbMissionsChicago: {
$sum: {
$cond: [
{
$eq: [{
$getField: {
field: { $literal: "$location" },
input: "$missions"
}
}, "Chicago"]
}, 1, 0
]
}
}
}
}
])
</code></pre>
<p>Here is the result :</p>
<pre><code>{ _id: 7698, name: 'Blake', nbMissionsChicago: 0 }
{ _id: 7782, name: 'Clark', nbMissionsChicago: 0 }
{ _id: 8000, name: 'Smith', nbMissionsChicago: 0 }
{ _id: 7902, name: 'Ford', nbMissionsChicago: 0 }
{ _id: 7499, name: 'Allen', nbMissionsChicago: 0 }
{ _id: 7654, name: 'Martin', nbMissionsChicago: 0 }
{ _id: 7900, name: 'James', nbMissionsChicago: 0 }
{ _id: 7369, name: 'Smith', nbMissionsChicago: 0 }
</code></pre>
<p>First of all, is there a better method to check that all the locations of the missions array respect the condition? And why does this commands returns only 0 ?</p>
<p>Thanks!</p>

74,252,741 | <p>A question dawned on me lately: Why bother having the <strong>scope resolution operator</strong> (<code>::</code>) when the usage of the <strong>dot operator</strong> (<code>.</code>) doesn't clash with the former?</p>
<p>Like,</p>
<pre><code>namespace my_module
{
const int insane_constant = 69;
int some_threshold = 100;
}
</code></pre>
<p>In order to access <code>some_threshold</code>, one would write <code>my_module::some_threshold</code>. But the thing is the left hand side of <code>::</code> must be a namespace or a class, as far as I know, while that of the <code>.</code> can never be a namespace or a class. Moreover, the order of <code>::</code> is higher than <code>.</code>, which is really pointless in my opinion. Why make 2 distinct operators, both of which cannot be overloaded, with use cases can be covered with just one? I'm having a hard time finding any satisfying answer, so any clue on this matter is much appriciated.</p>

74,252,828 | <p>I'm trying to add an image to a navbar, and I have countless issues regardless of the approach I take. The image "exits" the container when it is too big, the image isn't aligned in the center - vertically or horizontally, the image changes how the navbar looks depending on the size...</p>
<p>I just want an image that fits either at the end or just somewhere in my navbar, and moves with the other elements if I resize the page. (i.e. stays to the right of the other tags).</p>
<p>I have this code as part of the freecodecamp challenge of making a product landing page, and I'm trying to make a navbar, with the logo within the navbar. I wanted it at the right but I've since given up I just want it in it.</p>
<p>I've tried the W3School tutorials, tried using Flexbox (example in the code here) and a bunch of different things. The problem is that the image isn't "in the container." I can always modify its size and it will either exit the navbar, modify the navbar size... countless issues.</p>
<p>Here is the html & CSS:</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>html {
box-sizing: border-box;
}
nav {
display: flex;
flex-direction: row;
justify-content: space-evenly;
align-items: center;
background-color: rgba(0, 0, 0, 0.8);
height: 30px;
width: 100%;
}
li {
display: inline;
}
ul {
list-style-type: none;
padding: 0;
margin: 0;
}
a {
text-decoration: none;
color: white;
}
img {
display: inline;
width: 20px;
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code><header id="header">
<img id="header-img">
<nav id="nav-bar">
<ul>
<li><a class="nav-link" href="#Running">Push Farther. Run Wilder.</a></li>
<li><a class="nav-link" href="#Hiking">Above. Beyond. And Back Again.</a></li>
<li><a class="nav-link" href="#Diving">Groundbreaking, even in the sea.</a></li>
</ul>
<img src="https://cdn.freebiesupply.com/logos/large/2x/apple1-logo-png-transparent.png"></img>
</nav>
</header></code></pre>
</div>
</div>
</p>
<p>These are the issues that happen:</p>
<p>In this image I used height for the img, and a height occurs ON TOP of the navbar, plus the logo exits the navbar instead of being capped or something.</p>
<p><a href="https://i.stack.imgur.com/l75D1.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/l75D1.png" alt="enter image description here" /></a></p>
<p>With no size attribute, the logo becomes huge and all navbar related images disappear.
<a href="https://i.stack.imgur.com/ZrPcn.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ZrPcn.png" alt="enter image description here" /></a></p>
<p>And then without flexbox, getting the image to be in the navbar, properly sized, and aligned never happened.</p>
<p>Just not sure how to fix this, what I'm misunderstanding of CSS.. I've spent so long on this thing.</p>
<p>Thanks a lot for any help!</p>
<p>Edit:</p>
<p>For the fixes I've been shown, this error occurs:
<a href="https://i.stack.imgur.com/3j2m4.png" rel="nofollow noreferrer">enter image description here</a></p>
<p>As you can see, there is white space above the navbar. I gave the logo a red border so the whitespace is more visible and maybe it helps someone understand the problem.</p>

74,252,865 | <p>EDIT: found the answer thanks to James Brown, there was a problem in the way I formatted the command:</p>
<pre><code>awk -F"," '{ if ($2*$3 > 0.5) print }'
</code></pre>
<p>is working.</p>
<p>I've got a file like this:</p>
<pre><code>1000,0.5,1
2000,0.5,3
4000,1,3
5000,0.2,1
</code></pre>
<p>I need to multiply $2 and $3 for each line and check if the result is superior to 0.5.
I read that the -gt operator cannot handle floating-point numbers and that awk could do it.</p>
<p>Here's the best I could come up with:</p>
<pre><code>cat awk.txt | awk -F"," '{ if ("$2"*"$3" > "0,5") print "$line"}'
</code></pre>
<p>Of course, it doesn't work, but it doesn't return any error...</p>
<p>Expected result:</p>
<pre><code>5000,0.2,1
</code></pre>
<p>Can you point me in the right direction?</p>
<p>Thank you very much</p>

74,252,868 | <p>Assume I have a function that is defined for two float values, and this function is rather complex that is not easy to be modified. Now I have two same 2D arrays, say $X_{n \times m}, Y_{n \times m}$, I need to carry out the function on each element on the 2D array $x_{ij}, y_{ij}$. How can I speed this work with respect to the two for loops?</p>
<p>The following is the general code, in which the function has been simplified to be a summation:</p>
<pre><code>def func(x, y):
return x + y
X = np.random.rand(100, 100)
Y = np.random.rand(100, 100)
Z = np.zeros((100, 100))
for i in range(100):
for j in range(100):
z = func(X[i, j], Y[i, j])
Z[i, j] = z

74,252,978 | <p>I have a BiqQuery table (Table A) that has around 1,000 records containing an ID and 15 datapoints that range between 0 - 100. Imagine its like a top-trumps card but with 15 attributes. Here's an example:</p>
<pre><code>Record_ID = 0001
Size = 56
Height = 34
Width = 23
Weight = 78
Color = 42
Volume = 8
Density = 77
Smell = 23
Touch = 67
Hearing = 52
Power = 87
Sensitivity = 3
Strength = 78
Endurance = 45
Reliability = 87
</code></pre>
<p>And I have a separate table (Table B) that has exactly the same schema with around 5,000 different records</p>
<p>I need to take each Record_ID from Table A and then somehow rank the records in Table B that most closely match across all attributes. If I were just trying to rank records based on a single attribute such as Size then this would be really easy but I don't know where to start when I'm trying to find the closest matches and rankings across all attributes.</p>
<p>Is there any kind of model or approach that might help me achieve this? I have been reading up on clustering and K-means nearest neighbor but these don't seem to help.</p>

74,253,018 | <h1>The problem</h1>
<p>e.g.</p>
<p>list1 = ["a", "c", "b", "a", "b", "c", "a", "c", "b"]</p>
<p>list2 = ["a", "c", "a", "b"]</p>
<h2>Possibilities:</h2>
<h3>1.</h3>
<p>list1 = [<strong>"a"</strong>, <strong>"c"</strong>, "b", <strong>"a"</strong>, <strong>"b"</strong>, "c", "a", "c", "b"]</p>
<p>list2 = ["a", "c", "a", "b"]</p>
<p>those are indexes: [1, 2, 4, 5</p>
<h3>2.</h3>
<p>list1 = [<strong>"a"</strong>, <strong>"c"</strong>, "b", <strong>"a"</strong>, "b", "c", "a", "c", <strong>"b"</strong>]</p>
<p>list2 = ["a", "c", "a", "b"]</p>
<p>those are indexes: [1, 2, 4, 9]</p>
<h3>3.</h3>
<p>list1 = [<strong>"a"</strong>, <strong>"c"</strong>, "b", "a", "b", "c", <strong>"a"</strong>, "c", <strong>"b"</strong>]</p>
<p>list2 = ["a", "c", "a", "b"]</p>
<p>those are indexes: [1, 2, 7, 9]</p>
<h3>4.</h3>
<p>list1 = [<strong>"a"</strong>, "c", "b", "a", "b", <strong>"c"</strong>, <strong>"a"</strong>, "c", <strong>"b"</strong>]</p>
<p>list2 = ["a", "c", "a", "b"]</p>
<p>those are indexes: [1, 6, 7, 9]</p>
<h3>5.</h3>
<p>list1 = ["a", "c", "b", <strong>"a"</strong>, "b", <strong>"c"</strong>, <strong>"a"</strong>, "c", <strong>"b"</strong>]</p>
<p>list2 = ["a", "c", "a", "b"]</p>
<p>those are indexes: [4, 6, 7, 9]</p>
<h1>Output</h1>
<p>The output should be an array of indexes never used</p>
<p>for that above example it would be
[2, 8]
(because it never appears in the indexes)</p>
<p>I tried a whole amount of solutions and all I could do is determine whether list2 is a subsequence of list1 or not</p>

74,253,059 | <p>so I am trying to find the number of samples that are labelled with the phrase 'PaperB' in a very larger data frame in R, I have used the following:</p>
<p><code>df[grep("PaperB", names(df))]</code></p>
<p>but this has given me all the columns labelled with Tissue B and their values, rather than the total amount of PaperB samples, how could i change this to just get the total amount?</p>

74,253,077 | <p>I'm writing a program which will create 4 lists with words in them. A user is prompted to answer how many words they'd like to print from list A, how many from list B, how many from list C, D etc. and the program randomly chooses those words and prints them out.</p>
<p>I've got the shell out ready, the lists are made up, and the user input prompts are done, I can't figure out how to connect these two together. I can print out random values from a list using random.choice() but the amount that I specify. Not the number of words the user specifies.</p>
<p>The code is something like this:</p>
<pre><code>def lists():
animal = ["cat", "dog", "horse", "cow", "rabbit"]
furnishings = ["couch", "table", "chair", "lamp", "bed"]
vehicle = ["mazda", "toyota", "ford", "cadillac", "honda"]
shade = ["red", "blue", "black", "green", "purple"]
def inputFunction():
animals = input("how many animals would you like to print? ")
furniture = input("how many furniture pieces would you like to print? ")
cars = input("how many cars would like to use? ")
colors = input("how many colors? ")
def main():
</code></pre>
<p>***please note this is not the entire code but an oversimplified version of it to illustrate what I mean ***</p>
<p>The output I want is something along the lines of:</p>
<p>how many animals would you like to print? 2
how many furniture pieces would you like to print? 3
how many cars would like to use? 1
how many colors? 5</p>
<p>cat horse table lamp bed toyota red blue black green purple.</p>

74,253,083 | <p>Following the first answer to <a href="https://stackoverflow.com/questions/25153153/initializing-array-of-variable-size-inside-a-class">this question</a>, I ran into an issue with overriding variables. This is the code I wrote to find the root of the problem:</p>
<pre class="lang-cpp prettyprint-override"><code>#include <iostream>
using namespace std;
class foo
{
private:
int *bar;
int l;
public:
foo(int bar);
~foo();
void print_bar() {
cout << "bar = {"; for (int i = 0; i < l; i++) {cout << + bar[i] << ", ";} cout << "}" << endl;
}
};
foo::foo(int l) {
this->l = l;
cout << "Creating with length " << l << endl;
bar = new int[l];
cout << "{"; for (int i = 0; i < l; i++) {cout << + bar[i] << ", ";} cout << "}" << endl;
for(size_t i = 0; i < l; ++i) {bar[i] = 0;}
cout << "Created with bar = {"; for (int i = 0; i < l; i++) {cout << + bar[i] << ", ";} cout << "}" << endl;
}
foo::~foo() {
cout << "Deleted with bar = {"; for (int i = 0; i < l; i++) {cout << + bar[i] << ", ";} cout << "}" << endl;
delete[] bar;
}
int main() {
foo a = foo(1);
a = foo(2);
a.print_bar();
return 0;
}
</code></pre>
<p>This outputs:</p>
<pre><code>Creating with length 1
{0, }
Created with bar = {0, }
Creating with length 2
{0, 0, }
Created with bar = {0, 0, }
Deleted with bar = {0, 0, }
bar = {1431655787, 5, }
Deleted with bar = {1431655787, 5, }
</code></pre>
<p>Instead of what I expected:</p>
<pre><code>Creating with length 1
{0, }
Created with bar = {0, }
Creating with length 2
{0, 0, }
Created with bar = {0, 0, }
Deleted with bar = {0, }
bar = {0, 0, }
Deleted with bar = {0, 0, }
</code></pre>
<p>How can I avoid this, or is there a better way to have a class with a variable length array as a parameter?</p>
<p><em>(Please keep in mind when answering that I'm very new to c++.)</em></p>

74,253,160 | <p>I have a type that looks like this:</p>
<pre class="lang-js prettyprint-override"><code>type Config = {
endpoints: [
{name: "abc", created: false},
{name: "xyz", created: true},

</code></pre>
<p>I have a function that transforms this type into the following:</p>
<pre class="lang-js prettyprint-override"><code>type Instance = {
abc: {name: "abc", created: false},
xyz: {name: "xyz", created: false},
}
</code></pre>
<p>I wrote the following transformation type</p>
<pre class="lang-js prettyprint-override"><code>type IntersectOf<U extends any> = (U extends unknown ? (k: U) => void : never) extends ((k: infer I) => void) ? I : never;
type Transform<T extends Config, K extends (keyof T)[] = (keyof T)[]> = IntersectOf<{
[key in keyof K]:
K[key] extends keyof T['endpoints']
// here it says "name" can't be used as index of `T["endpoints"][K[key]]`
? Record<T['endpoints'][K[key]]['name'], T['endpoints'][K[key]]>
: never;
}[number]>;
type Instance = Transform<Config>;
</code></pre>
<p>I also tried adding a number type guard, and the error goes away but <code>Instance</code> becomes <code>unknown</code>. Here is the <code>Transform</code> type with number typeguard:</p>
<pre class="lang-js prettyprint-override"><code>type Trasnform<T extends Config, K extends (keyof T)[] = (keyof T)[]> = IntersectOf<{

<p>and don't know how to stop such a macro at the end of the document (break the loop) without using a</p>

<p>It wouldn't be a problem, but the macro sometimes stops at the end-of-paragraph characters, interpreting them as the end of the document.
[EDIT]
Ok-ActiveDocument.Range.Characters.Last
Still returns empty - that's why it stops. I should not use this.</p>

74,253,411 | <p>I have a data frame with 70k rows and two columns. Col1 contains bill of materials name and customer, Col2 contains a part number (which is a part of the BOM).</p>

<p>When searching for Cust1, I want to see in column3 if the part number is purchased exclusively for that customer. Something like this:</p>
<pre><code> Col1 Col2 Col3

8 ROW, Cust3 1005 false
9 HON, Cust3 1005 false

<p>I already tried to extract duplicates with df.duplicated and to evaluate the customer name with str.contains, but without satisfying result. Is there a smart solution that I don't know?
I am new to python and getting nowhere with this problem.</p>

df1 has multiple columns ("x", "y" , "z"), with possible values 0,1, or NA. df2 has two columns: "a" and "b". The values of column "b" include the column names of df1 (although some values in df2$a may be present as columns in df1).</p>
<pre><code>x <- c(1, 1, NA, NA, 0)
y <- c(0, 1, 1, NA, NA)
z <- c(1, 1, 0, 1, 1)
df1 <- data.frame(x, y, z)
a <- c( "Green", "Green", "Green", "Red", "Red", "Blue", "Blue", "Yellow")
b <- c( "w", "x", "y", "x", "z", "w" , "y", "z" )
df2 <- data.frame(a, b)
</code></pre>
<p>The new columns to be created in df1 should be named as the values of column df2$a. The value of each new column (i.e df1$Green) should be "1" when</p>
<ul>
<li>the values of df2$a and df2$b are matched (example: df2$a = "Green" matches df2$b = "w", "x" and "y"), and</li>
<li>the corresponding column in df1 (df1$x and df$y) equals "1".</li>
</ul>
<p>The new_df1 should be:</p>

x y z Green Red Blue Yellow

74,253,468 | <p>Mapstruct always generate mappers that use a default empty constructor and setters to construct an object.</p>
<p>I need mapstruct to construct objects using parameterized constructor instead.</p>

<pre><code>@Mapper(componentModel = "spring")
public interface FlightMapper {
FlightBooking flightBookingPostRequestDtoToFlightBooking(FlightBookingPostRequestDto flightBookingDto);
}
</code></pre>
<p>The implementation that mapstruct generates uses the default constructor without parameters:</p>
<pre><code>public FlightBooking flightBookingPostRequestDtoToFlightBooking(FlightBookingPostRequestDto flightBookingDto) {
if ( flightBookingDto == null ) {
return null;
}
FlightBooking flightBooking = new FlightBooking();
flightBooking.setFlight_booking_id( flightBookingDto.getBooking_id() );
return flightBooking;
}
</code></pre>
<p>But I need this implementation with a parameterized constructor instead:</p>
<pre><code>public FlightBooking flightBookingPostRequestDtoToFlightBooking(FlightBookingPostRequestDto flightBookingDto) {
if ( flightBookingDto == null ) {
return null;
}
FlightBooking flightBooking = new FlightBooking(flightBookingDto.getBooking_id());
return flightBooking;
}

const [store, dispatch] = Store();
return (
<div>
<span>counter from OtherComponent.js:{store.counter}</span>
</div>
);
};
export default OtherComponent.js;
</code></pre>
<p>So basically like in Redux, create a one Store where you store everything. In AnyComponent.js we have button who increase counter by 1 so we can see that value of store.counter in AnyComponent.js and OtherComponent.js.<br/>
Please anyone tell me if anything is wrong with this code?<br/>
Will try to upload this to GitHub later.<br/></p>
<p>I looked in web and did not found anything what is similar to this so please let me know what you think.</p>

74,253,559 | <p>I am converting python 2.7 to python 3.9 with pandas 1.1.5 currently. The below code working in python 2.7 but caused an error when it is in 3.9 (or due to upgrading pandas as well)</p>
<pre><code>agent = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36'

<p>The error as below
<code>TypeError: int() argument must be a string, a bytes-like object or a number, not '_NoValueType'</code>
in line <code>data = pd.DataFrame(data['quoteResponse']['result'])</code>. Why the error occurred and how to fix.</p>

74,253,563 | <p>Considering the following code :</p>
<pre><code>switch(checkState) {
case 0: pixel.addEventListener('mouseover', addColor);
console.log("test");
break;
case 1: pixel.removeEventListener('mouseover', addColor);
console.log("test2");
break;
}
</code></pre>
<p>The function containing this switch statement is called on other event, and should either add listeners if checkState === 0, or remove them if checkState === 1. But listeners aren't removed on checkState === 1, despite "test2" showing in the console.</p>
<p>I made sure that :</p>
<ul>
<li>addColor is a declared function (so both addEvent and removeEvent reference the same function) ;</li>
<li>both handlers refer the same DOM elements ;</li>
<li>Not using the .bind method.</li>
</ul>
<p>I also dug into <a href="https://stackoverflow.com/questions/10444077/javascript-removeeventlistener-not-working">this topic</a> but unfortunately didn't find the solution.</p>
<p>Here is a <a href="https://replit.com/@hirono9730/ValidBoringRadius#script.js" rel="nofollow noreferrer">replit</a>.</p>

74,253,737 | <p>I have millions of < 20 char strings, and I want to compress each of them <em>individually</em>.</p>
<p>Using <code>zlib</code> or <code>lz4</code> on each string individually doesn't work: the output is bigger than the input:</p>

<p>Is there a way in Python (maybe with zlib or lz4?) to use a <strong>dictionary-based compression</strong>, with a custom dictionary size (for example 64 KB or 1 MB) <strong>that would allow compression of very short strings <em>individually</em></strong>?</p>
<pre><code>inputs = [b"hello world", b"foo bar", b"HELLO foo bar world", b"bar foo 1234", b"12345 barfoo"]
D = DictionaryCompressor(dictionary_size=1_000_000)
for s in inputs:
D.update(s)
# now the dictionary is ready
for s in inputs:
print(D.compress(s))

74,253,787 | <p>I am developing a search engine for a website; now it's working fine and responding to input search keywords with no issues in its interaction with the (Django-based) local web server. The problem (well there are actually two, but I'm presenting only one here) is with the datalist. When I select an option from the list, although it goes into the search input field, nothing happens until I click the submit button.</p>
<p>I have written an event listener for each option, but I'm clearly missing something (important). Here's my minimal working 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-js lang-js prettyprint-override"><code> const searchForm = document.getElementById('search-form');
const enter = document.getElementById('enter');
let options = document.querySelectorAll(".option");
options.forEach((item, index) => {
item.addEventListener("click", () => {
return searchForm.action;
})
})</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code><form id="search-form" action ="{% url 'search' %}" method='POST'>
{% csrf_token %}
<input id="enter" type="search" list="options" name="query" />
<datalist id="options">
<option class="option" value="Happy">
<option class="option" value="Puzzled">
</datalist>
<button id="go" type="submit"><strong>&#x1F50E;&#xFE0E;</strong></button>
<button id="reset" type="reset"><strong>X</strong></button>
</form></code></pre>
</div>
</div>
</p>
<p>Maybe the event should be something else; I've tried "keydown" and clicking twice but nothing has worked.</p>

74,253,871 | <p>I am supposed to solve this problem in as low time complexity as possible, but let me be more specific.</p>
<p>You are given a sorted array of integers that contains duplicates.</p>
<p>Unique quadruple is a set of four indexes. Elements from the array under those indexes have to sum to a given value X. For example:</p>
<ol>
<li><p>Given an array [10, 20, 30, 40] and X = 100, there is only one quadruple:
(0, 1, 2, 3).</p>
</li>
<li><p>Given an array [0, 0, 0, 0, 0] and X = 0, there are 5 quadruples:
(0, 1, 2, 3),
(0, 1, 2, 4),
(0, 1, 3, 4),
(0, 2, 3, 4),
(1, 2, 3, 4).</p>
</li>
</ol>
<p>On the Internet there are plenty of N^3 solutions, but those are for unique quadruples in terms on values, not indexes. In those solutions, example number 1 would still give only one quadruple: (10, 20, 30, 40), but example number 2 gives only one quadruple (0, 0, 0, 0), not five of them.</p>
<p>I couldn't find a O(N^3) solution that would solve my problem instead of the other one. I can easily write a program that solves it in O(N^3logN) time. I also heard that the lower complexity bound for this problem is allegedly not known. Is there a O(N^3) solution known though?</p>
<p>Solutions known to me:</p>
<ol>
<li><p>Obvious naive approach O(N^4):</p>
<pre class="lang-cpp prettyprint-override"><code>int solution(int arr[], int arrSize, int X){
int counter = 0;
for(int i=0; i<arrSize-3; ++i)
for(int j=i+1; j<arrSize-2; ++j)
for(int k=j+1; k<arrSize-1; ++k)
for(int l=k+1; l<arrSize; ++l)
if(arr[i] + arr[j] + arr[k] + arr[l] == X)
++counter;
return counter;
}
</code></pre>
</li>
<li><p>Approach using triplets and binary search O(N^3logN):</p>
<pre class="lang-cpp prettyprint-override"><code>int solution(int arr[], int arrSize, int X){
int counter = 0;
for(int i=0; i<arrSize-3; ++i)
for(int j=i+1; j<arrSize-2; ++j)
for(int k=j+1; k<arrSize-1; ++k){
int subX = X - arr[i] - arr[j] - arr[k];
int first = binFirst(subX, arr, k+1, arrSize);
// Binary search that returns the position of the first
// occurrence of subX in arr in range [k+1, arrSize)
// or -1 if not found
int last = binLast(subX, arr, k+1, arrSize);
// Binary search that returns the position of the last
// occurrence of subX in arr in range [k+1, arrSize)
// or -1 if not found
if(first != -1)
counter += last - first + 1;
return counter;
</code></pre>
</li>
</ol>
<p>Naturally, the above algorithm could be improved by counting all duplicates of arr[i], arr[j], arr[k], but as far as I can tell, it does not lower the actual O(N^3logN) complexity.</p>

74,253,875 | <p>Im trying to make an Star Pattern Generator in Flutter. I pass Data from type int in a callback function from the child widget: Textfield Widget to the parent Widget CustomBarWidget and after to the Toplevel parent Widget RootPage.</p>
<p>At the Textfield I got an Error at the Line:</p>
<pre><code>onChanged: widget.onChange,
</code></pre>
<p>The Error says: The argument type 'dynamic Function(int)' can't be assigned to the parameter type void Function(String)?</p>
<p>Here is the Full Code:</p>
<p>RootPage:</p>
<pre><code>class RootPage extends StatefulWidget {
const RootPage({super.key});
@override
State<RootPage> createState() => _RootPageState();
}
class _RootPageState extends State<RootPage> {
int data = 5;
void getData(int newNumb) {
setState(() {
data = newNumb;
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: CustomBarWidget(sendData: getData),
body: StarTriangleWidget(data: data),
);
}
}
</code></pre>
<p>CustomBarWidget:</p>
<pre><code>class CustomBarWidget extends StatefulWidget implements PreferredSizeWidget {
const CustomBarWidget({super.key, this.sendData});
final sendData;
@override
Size get preferredSize => const Size.fromHeight(70.0);
@override
State<CustomBarWidget> createState() => _CustomBarWidgetState();
}
class _CustomBarWidgetState extends State<CustomBarWidget> {
int data = 0;
@override
Widget build(BuildContext context) {
return AppBar(
backgroundColor: Colors.transparent,
elevation: 0,
title: Row(
children: <Widget>[
TextfielWidget(onChange: (val) {
widget.sendData(val);
}),
ElevatedButton(
onPressed: () {
debugPrint("click");
},
style: ElevatedButton.styleFrom(
padding:
const EdgeInsets.symmetric(horizontal: 40.0, vertical: 15.0),
shape: const StadiumBorder(),
),
child: const Text(
"Enter",
style: TextStyle(color: Colors.white, fontSize: 18),
),
),
],
),
);
}
}
</code></pre>
<p>textfieldWidget:</p>
<pre><code>class TextfielWidget extends StatefulWidget {
final Function(int) onChange;
const TextfielWidget({super.key, required this.onChange});
@override
State<TextfielWidget> createState() => _TextfielWidgetState();
}
class _TextfielWidgetState extends State<TextfielWidget> {
@override
Widget build(BuildContext context) {
return Flexible(
child: TextField(
onChanged: widget.onChange,
keyboardType: TextInputType.number,
decoration: const InputDecoration(
border: OutlineInputBorder(),
labelText: 'Enter Number',
)
)
);
}
}
</code></pre>
<p>Where can I change the type of "void Function(String)?"?
I can't find the Problem, is the Problem the Textfield itself?</p>
<p>Thank you for help</p>

74,253,903 | <p>I am working with R and I have a series x at quarterly frequency and for which I want to extract the mean over the four quarters in 2012 and store that value in all rows of a newly created column. I have this kind of dataset</p>
<pre><code>date durabl services
2011-10-01 56.7 37.1
2012-01-01 68.1 90.6
2012-04-01 34.1 29.1
2012-07-01 22.56 34.12
2012-10-01 44.89 66.8
</code></pre>
<p>And I want to get to this</p>
<pre><code>date durabl services base_durabl base_services
2011-10-01 56.7 37.1 42.4125 55.155
2012-01-01 68.1 90.6 42.4125 55.155
2012-04-01 34.1 29.1 42.4125 55.155
2012-07-01 22.56 34.12 42.4125 55.155
2012-10-01 44.89 66.8 42.4125 55.155
</code></pre>
<p>I tried using dplyr</p>
<pre><code>df %>% group_by(year(date)) %>% filter(year(date)==2012) %>% mutate(base_durabl= mean(durabl),base_services=mean(services))
</code></pre>
<p>or with summarise but of course I just get a smaller tibble.</p>

74,253,946 | <p>I will start this by saying I have read all of the posts I have found on here regarding this issue and have troubleshot all of the solutions suggested, and none have worked. I have also tried all of the suggestions from the AWS and MySQL websites themselves to no avail. I believe the issue is a Security issue, but I'm not sure where the issue is. All of these were set to Public. So far I have done the following:
MySQL side:
-Installed Visual Studio 2019 toggled so that it can use the MySQL for Visual Studio in case I need it (Currently, my plan is to use Eclipse as my IDE, but this is my first time interfacing with MySQL in Java and I'm not sure if I will be able to use the Connector directly with Eclipse or if I will need this)
-I installed 8.0.31, but rolled it back believing it may have been an issue with 8.0.31 being newer than 8.0.30 and seeing there is no documentation saying this version is compatible with RDS in Amazon's documentation
-Installed 8.0.30 as both Developer and Custom (installed MySQL Server, MySQL Workbench, MySQL for Visual Studio, MySQL Shell, Connector/J)</p>
<p>From RDS I have done the following:
-Created 3 different Databases, 2 using the "Standard" mode, 1 using the "Easy" mode. The 2 using the "Standard" mode were toggled with one using an EC2 and one not using an EC2.
-For all 3 Databases, I went in and Edited the Inbound Rules to add a rule of "All traffic" and "Anywhere-IPv4". I'm aware this is actually a security risk, but this is for a school project and I'm literally trying to connect to the Database. Currently, I'm the only person who needs to connect to the Database and when I can actually do it, I will limit it to my IP Address.</p>
<p>I have tried connecting from the Workbench itself and also from the Command Prompt, but I cannot find any more suggestions for what can be the issue. I have also changed the name of the Masteruser (to "root" and "root user") and simplified the Masterpassword. This is for a school project so no confidential information is in it. I have literally spent an entire day trying to solve this issue and have no idea what else it could be unless it is the admin as I am not the Admin. I have seen a suggestion to make sure the Subnet for the Internet Gateway is active, but I haven't seen information on how to actually verify this, so if this is likely the issue, information on how to check this would be very useful.</p>

74,253,949 | <p>How to finish the forever when another component has finished in uvm?
There is 2 components first component_a just send transaction from uvm_tlm_analysis_fifo.
and other component_b keep polling the received transaction.
I want if component_a has finished then component_b also finished.</p>
<p>But currently component_b never stop because it is along with forever statement.</p>
<p>How do I finish the another component's process? component_b never stop.</p>
<pre><code>class basic_test extends uvm_test;
..
task run_phase(uvm_phase phase);
phase.raise_objection(this); // raise an objection
#500;
phase.drop_objection(this); // drop an objection
endtask: run_phase
endclass
class component_a extends uvm_component;
transaction trans;
...
uvm_analysis_port#(transaction) analysis_port;
...
virtual task run_phase(uvm_phase phase);
for(int a=0; a<10; a++) begin
trans = transaction::type_id::create("trans");
if (!trans.randomize())
`uvm_fatal("RNDERR", "Randomization of trans failed");
analysis_port.write(trans);
`uvm_info(get_type_name(), "Trans Sending....",UVM_LOW)
end
endtask
endclass
class component_b extends uvm_component;
...
virtual task run_phase(uvm_phase phase);
...
forever begin
`uvm_info(get_type_name(), $sformatf(" FIFO used: %0d", analy_fifo.used()), UVM_LOW)
if(analy_fifo.is_empty()) begin
`uvm_info(get_type_name(), "FIFO is Empty!!!!!",UVM_LOW)
end
else begin
analy_fifo.get(trans);
`uvm_info(get_type_name(),$sformatf(" Printing receive trans, \n ",trans.sprint()),UVM_LOW)
end
end
endtask
endclass
</code></pre>
<p>I expected that component_b working as background but I only get the printg as below</p>
<pre><code>UVM_INFO component_b.sv(55) @ 0: uvm_test_top.env.comp_b [component_b] FIFO is Empty!!!!!
UVM_INFO component_b.sv(52) @ 0: uvm_test_top.env.comp_b [component_b] FIFO used: 0
UVM_INFO component_b.sv(55) @ 0: uvm_test_top.env.comp_b [component_b] FIFO is Empty!!!!!
UVM_INFO component_b.sv(52) @ 0: uvm_test_top.env.comp_b [component_b] FIFO used: 0
...
</code></pre>
<p>There is no time consume by test and component_a has no chance to work.</p>

74,253,980 | <p>I have an array of pointers, <code>componentArray</code>, but I'm struggling to figure out the syntax to both render them in <code>ParentComponent</code></p>
<pre class="lang-js prettyprint-override"><code>
function Component1() {
return(
<h1>Hello from Component 1</h1>
);
}
function Component2() {
return(
<h1>Hello from Component 2</h1>
);
}
export const componentObject = [{
name: "Component1",
pointer: Component1
}, {
name: "Component2",
pointer: Component2
}];
function ParentComponent(props) {
return (
<div>
{Object.entries(componentObject).map((ChildComponent) => (
<span>{ChildComponent[1]() DOESNOTWORKPROP="Test"}</span>
))}
</div>
);
};
</code></pre>
<p>The above will work if you remove <code>DOESNOTWKRPROP="TEST"</code>, but will not work when trying to add props to the children.</p>

74,254,066 | <p>I have a table where I have students name, their ID and a bit to signify whether or not they passed a certain subject. Ultimately, I would like to group by all the subjects in 1 report / query where individuals have passed.
I couldnt figure out how to script this so I just did a <code>select *</code> and elected to try in crystal reports.</p>
<p>This is my Data.</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th style="text-align: left;">ID</th>
<th style="text-align: center;">Name</th>
<th style="text-align: center;">passMath</th>
<th style="text-align: center;">passScience</th>
<th style="text-align: center;">passFrench</th>
</tr>
</thead>
<tbody>
<tr>
<td style="text-align: left;">1</td>
<td style="text-align: center;">Peter</td>
<td style="text-align: center;">1</td>
<td style="text-align: center;">0</td>
<td style="text-align: center;">1</td>
</tr>
<tr>
<td style="text-align: left;">2</td>
<td style="text-align: center;">John</td>
<td style="text-align: center;">1</td>
<td style="text-align: center;">1</td>
<td style="text-align: center;">1</td>
</tr>
<tr>
<td style="text-align: left;">3</td>
<td style="text-align: center;">Kacy</td>
<td style="text-align: center;">0</td>
<td style="text-align: center;">1</td>
<td style="text-align: center;">1</td>
</tr>
</tbody>
</table>
</div>
<p>And this is the expected results, or what I am ultimately trying to show in a report. Basically, in my crystal report, I'll have a secion<br />
<strong>Math</strong></p>
<p>Peter</p>
<p><strong>Science</strong></p>
<p>John</p>
<p>Kacy</p>
<p><strong>French</strong></p>
<p>Peter</p>
<p>John</p>
<p>Kacy</p>
<p><strong>What have I tried</strong></p>
<p>Now, I haven't figured out how to do this in a query, so what I did is, following the answer from this link I tried to <a href="https://stackoverflow.com/questions/64811666/add-a-conditional-row-in-crystal-report">conditionally render a section</a>.</p>
<p>My issue is, this sort of works but the results it's returning is.</p>
<p><strong>passMath</strong></p>
<p>Peter</p>
<p>passScience</p>
<p>John</p>
<p><strong>passMath</strong></p>
<p>John</p>
<p>Basically, instead of grouping everyone who passed math together, it's giving them their separate row. So John and Peter both create a section titled "passMath" where I want them to be grouped together. What I did in crystal report was to create a section>section expert and add <code>{usp_student.passMath}= false</code> to the formula area where I expect it to suppress all records that didnt pass Math. So far it works 50% And I would like it to group them all.</p>
<p>Appreciate if I could get help with this query or a way to fix the crystal report.</p>
