74,437,772 | <p>In the background does the app still running even though I'm not currently on that tab, or when I move between tabs, the current tab I was, in is getting paused and after I open that tab again it makes a request to the server to get the newer changes from the database?</p>
<p>Edit: The problem which I currently have is:
I have an expiration timer where the reservation needs to be closed after 5 min if there is no activity, now if I open a new tab and come back after e.g. 10 min, the reservation sometimes is closed and it shows good on the front end and back end, sometimes the reservation will close on the backend but the front end will not be updated.</p>
<p>If I'm on that tab then everything works, but when I switch tabs and come back after some time I have a problem.</p>

74,437,776 | <p>If the data is to be removed, I find the element with findIndex and discard it as a null value in isInArray. If there is no such data, how do I add it to the empty element starting from the first element?

74,437,796 | <p><em>New to OOP and python</em>, I am <em>struggling enormously</em> to grasp what good <em>classes actually are for</em>. I tried to ask <em>help from a lecturer</em> who said "oh, then you should read about general methods to classes". <em>Been putting in a days work but get no where</em>.</p>
<p>I get it that a class allow you to collect an instance structure and methods to it, like this:</p>
<pre><code>class Items:
def __init__(self, item_id, item_name):
self.item_id = item_id
self.item_name = item_name
def show_list(self):
print(self.item_id, self.item_name)
idA = Items("idA", "A")
idA.show_list()
</code></pre>
<p><strong>But what is even the point</strong> of a class if there were not MANY instances you would classify? If I have a method within the class, I must hard code the actual instance to call the class for. What if you want a user to search and select an instance, to then do operations to (e.g. print, compute or whatever)??</p>
<p>I thought of doing it like this:</p>
<pre><code>class Items:
def __init__(self, item_id, item_name):
self.item_id = item_id
self.item_name = item_name
def show_list(self):
print(self.item_id, self.item_name)
idA = Items("idA", "A")
idB = Items("idB", "B")
select_item = input("enter item id")
select_item.show_list()
</code></pre>
<p>Replacing hard coded variable with input variable doesn't work, probably logically. I then played with the idea of doing it like this:</p>
<pre><code>class Items:
def __init__(self, item_id, item_name):
self.item_id = item_id
self.item_name = item_name
iL = [Items('idA', 'A'), Items('idB', 'B')]
selected_item = input("enter item id")
for selected_item in iL:
print(f'{selected_item.item_id} {selected_item.item_name}')
</code></pre>
<p>Now all are called thanks to making it a list instead of separate instances, but how do I actually apply code to filter and only use one instance in the list (dynamically, based on input)?</p>
<p>I would love the one who brought me sense to classes. You guys who work interactively with large data sets must do something what I today believe exist in another dimension.</p>
<p>See examples above^^</p>

74,437,826 | <p>The title might be quite vague, but here is the code: <a href="https://github.com/amorfis/why-no-implicit" rel="nofollow noreferrer">https://github.com/amorfis/why-no-implicit</a></p>
<p>So there is a tool to transform <code>Map[String, Any]</code> to a simple case class. The tests pass and this piece of code illustrates what it is all about:</p>
<pre><code> case class TargetData(
groupId: String,
validForAnalysis: Boolean,
applicationId: Int
)
val map = Map(
"groupId" -> "123456712345",
"applicationId" -> 31,
"validForAnalysis" -> true
)
val transformed: TargetData = MapDecoder.to[TargetData](map).transform
</code></pre>
<p>This code works. It nicely creates the case class instance when provided the simple <code>map</code></p>
<p>However, the <code>transform</code> method has to be called "outside" - just like in the example. When I try to move it to the <code>MapDecoder.to</code> method - the compiler complains about the missing implicit.</p>
<p>So I change the code in <code>MapDecoder.to</code> from this:</p>
<pre><code>def to[A](map: Map[String, Any]) = new MapDecoderH[A](map)
</code></pre>
<p>to this:</p>
<pre><code>def to[A](map: Map[String, Any]) = new MapDecoderH[A](map).transform
</code></pre>
<p>and it stops working. Why is that? Why the implicit is provided in one case but not in the other? All that changes is that I want to call the <code>transform</code> method in other place to have <code>MapDecoder.to</code> returning the case class not some transformer.</p>
<p>UPDATE:</p>
<p>What if I want to implement <code>to[A]</code> method inside an object I want to transform? Let's call it <code>DataFrame</code>, and I want this code to work:</p>
<pre><code>val df: DataFrame = ...
df.to[TargetData] // There is no apply called here
</code></pre>
<p>The problem is in such case there is nothing to pass to <code>apply</code>. It is also not feasible to call it with parens (<code>df.to[TargetData]()</code>) because then the compiler requires implicits in parens. Is it even possible to solve it without using macros?</p>

74,437,830 | <p>How do I end a program that reads an input line by line and it ends when there's a period (whitespace doesn't matter)?</p>
<p>For example:</p>
<pre><code>input = "HI
bye
."

<p>the program should end after it reaches the period.</p>
<p>I tried doing two things:</p>
<pre><code>if line == ".":
break
if "." in line:
break
</code></pre>
<p>but the first one doesn't consider whitespace, and the second one doesn't consider "." in numbers like <em>2.1</em>.</p>

74,437,910 | <p>Given the following list:</p>
<pre><code>dbset = [[{'id': '10556', 'nation': 'France', 'worth': '70'}], [{'id': '14808', 'nation': 'France', 'worth': '65'}], [{'id': '11446', 'nation': 'Ghana', 'worth': '69'}], [{'id': '11419', 'nation': 'France', 'worth': '69'}], [{'id': '11185', 'nation': 'Ghana', 'worth': '69'}], [{'id': '1527', 'nation': 'Ghana', 'worth': '64'}], [{'id': '12714', 'nation': 'Moldova', 'worth': '67'}], [{'id': '2855', 'nation': 'Moldova', 'worth': '63'}], [{'id': '9620', 'nation': 'Moldova', 'worth': '71'}]]
</code></pre>
<p>I know how to find all permutations of length 4 with:</p>
<pre><code>from itertools import permutations
perms = permutations(dbset,4)
</code></pre>
<p>Now comes the part where I struggle; I want the maximum times a nation is in the permutation to be equal to 2 and I also would like the total worth to be above 300.</p>
<p><strong>---Update---</strong></p>
<p>I managed to get this working for the limited sample with limited permutations. The sample size however, is a set with over 16000 records and the permutation size is 11. As of yet, I am still executing it for the first time with 2 criteria: avg worth = 80 and nation occurrence <= 5.</p>
<p>It's been running for over an hour now... any way to improve?</p>

<p>It will be used to feed:

<p><code>w</code> and <code>h</code> have to be both generators.</p>

74,438,095 | <p>I want to replace every string in and number in an object with an empty string of empty number.</p>

lala: "more strings",
d: "saaa"

<p>I can't think of an easy way to iterate over all the values in the object/array recursively. Is there a library (maybe lodash) that does this already?</p>

74,438,112 | <p>I been kinda stumped for a couple hours trying to figure out what to set as my default value on my createContext function. This is my code.</p>
<pre><code>// PetTypeProvider.tsx
import { useState, createContext, useContext } from 'react';
const PetTypeContext = createContext('');
const UpdatePetTypeContext = createContext((event:React.MouseEvent<HTMLElement>) => event);
export function usePetType() {
return useContext(PetTypeContext)
}
export function useUpdatePetType() {
return useContext(UpdatePetTypeContext)
}
interface PetTypeProviderProps {
children: JSX.Element|JSX.Element[];
}
export const PetTypeProvider: React.FC<PetTypeProviderProps> = ({children}) => {
const [petType, setPetType] = useState('Dogs');
const togglePet = (event:React.MouseEvent<HTMLElement>) => setPetType(event.currentTarget.innerText);
return (
<PetTypeContext.Provider value={petType}>
<UpdatePetTypeContext.Provider value={togglePet}>
{children}
</UpdatePetTypeContext.Provider>
</PetTypeContext.Provider>
);
};
</code></pre>
<p>On my <UpdatePetTypeContext.Provider> I set the value to my toggle function, which switches the pet type to which ever is selected.</p>
<pre><code> const togglePet = (event:React.MouseEvent<HTMLElement>) => setPetType(event.currentTarget.innerText);
</code></pre>
<p>TS compiler is yelling at me with this</p>
<pre><code>Type '(event: React.MouseEvent<HTMLElement>) => void' is not assignable to type '(event: React.MouseEvent<HTMLElement>) => React.MouseEvent<HTMLElement, MouseEvent>'.
Type 'void' is not assignable to type 'MouseEvent<HTMLElement, MouseEvent>'.ts(2322)
index.d.ts(329, 9): The expected type comes from property 'value' which is declared here on type 'IntrinsicAttributes & ProviderProps<(event: MouseEvent<HTMLElement, MouseEvent>) => MouseEvent<HTMLElement, MouseEvent>>'
</code></pre>
<p>Thanks for taking the time to read my issue</p>
<p>I have tried setting the to <code>const PetTypeContext = createContext(MouseEvent);</code> which didn't work. I honestly just need the correct default value and data type for TS and I am just lost. The code works, but TS compiler doesn't like it since no default value is given.</p>

74,438,203 | <p>I have a collection that pulls state data from an HRIS on a daily basis. We can use state data for all kinds of interesting things, like predictive analytics.</p>
<p>However, state change data grows boundlessly (currently, that's another piece of tech debt that we need to tackle). I would like to start however by creating a view that takes only the most recent record from the collection. So I have the following view creation code:</p>
<pre><code>db.rawEmployeeStatus.aggregate().match({dateOfStateCapture:
db.rawEmployeeStatus.find({})
.sort({$natural : -1})
.limit(1)
.toArray()[0]
.dateOfStateCapture})
.saveAsView("employeeStatusCurrentState",{dropIfExists:false})
</code></pre>
<p>However, the problem with this view, is that it gets most recent record <em>at the time the view is created</em>, then uses that data for the view. When ideally, the data in the view should always be populated from the most recent records in the collection.</p>

I am trying to write a new method to print out each element in the array I have created but my for loop is not recognising the existence of the array that has been created above it. It is giving me an error at the 'students.Length' part.</p>
<p>I'm sorry if this is a really stupid question because I feel like there's a very simple answer to this but I just can't understand why it's telling me the 'students' array doesn't exist?</p>

student.forename = fname;
student.surname = surname;
student.id_number = id_number;
student.averageGrade = 0.0F;
}
public static void Main(string[] args)
{
student_data[] students = new student_data[4];
populateStruct(out students[0], "Mark", "Anderson", 1);
populateStruct(out students[1], "Max", "Fisher", 2);
populateStruct(out students[2], "Tom", "Jones", 3);

74,438,283 | <p>I could not find a way to run a T-SQL Script using <a href="https://pypi.org/project/pyodbc/" rel="nofollow noreferrer">pyodbc</a> without having to change the script content.</p>
<p>Here's the simple SQL script file I'm trying to run:</p>
<pre><code>SET NOCOUNT ON
USE db_test
GO
CREATE OR ALTER FUNCTION usf_test()
RETURNS NVARCHAR(10)
BEGIN
DECLARE @var NVARCHAR(10)
SELECT @var = 'TEST'
RETURN @var
END

<p>and this is the python code I'm using:</p>
<pre><code>cursor.execute(file_content)
cursor.fetchall()
</code></pre>
<p>This is the error message: <code>pyodbc.ProgrammingError: ('42000', "[42000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Incorrect syntax near 'GO'. (102) (SQLExecDirectW)")</code> and yes, this runs with no errors directly on SSMS.</p>
<p>Is there a way to run a T-SQL script using pyodbc (or any other lib that supports SQL Server) in Python?</p>
<p>Notice I can't change the script content, so splitting it into multiple statements is not an option. I have to run the script just as it is on the file.</p>

74,438,284 | <p>A colleague wrote some Perl code (v5.30.0) that does all of this:</p>
<pre><code>#!/usr/bin/perl
use warnings;
use strict;
use Data::Dumper;
package main;
sub processScalarHash
{
my $bar = $_[0];
printf "A subroutine can access the scalar hash: \"%s\"\n", $bar->{'key3'};
}
# Build the "Scalar Hash":
my $scalarHash = {};
$scalarHash->{'key1'} = 'dog';
$scalarHash->{'key2'} = 'cat';
$scalarHash->{'key3'} = 'fish';
bless $scalarHash;
printf "I can examine the scalar hash:\n";
print Dumper(\$scalarHash);
printf "I can access the scalar hash: \"%s\"\n", $scalarHash->{'key1'};
my $tmpStr = 'key2';
printf "I can access the scalar hash: \"%s\"\n", $scalarHash->{$tmpStr};
processScalarHash($scalarHash);
</code></pre>
<p>Output is:</p>
<pre><code>me@ubuntu01$ ./ScalarHash.perl
I can examine the scalar hash:
$VAR1 = \bless( {
'key3' => 'fish',
'key1' => 'dog',
'key2' => 'cat'
}, 'main' );
I can access the scalar hash: "dog"
I can access the scalar hash: "cat"
A subroutine can access the scalar hash: "fish"
me@ubuntu01$
</code></pre>
<p>I'm just learning Perl myself, and what strikes me here is that I never see any documentation about referencing hashes with scalar ($) variables. With hash (%) and array (@) variables, yes, but never scalars ($)! I don't know why my colleague coded like this, but I have a sinking feeling that using "scalar hashes" is a very bad practice.</p>
<p>Asking as a Perl newbie: Is this bad coding? The last thing I want to do is perpetuate bad habits that could bite me later.</p>

<p>...this code works - I've run it and after the third call of next(), it returns bankrupt - but why? Surely when next() is called the third time, the loop will check the balance (which will still be 10 at that point), and then add -15 to the balance, and yield out -5...leaving the next iteration to yield bankrupt.</p>
<p>But thats obviously not the case, the balance seems to be updated with the yield value before the loop checks the current balance, but if that line of code is running first, then why is the loop running at all? wouldn't it just be yielding out the updated balance instantly?...so, which code is being run when?</p>

74,438,303 | <p>Hi I am trying to automatically save the customer on post without having to list it in the forms. It currently shows the drop down and saves correctly but if I remove customer from forms.py it doesn't save anymore.
views.py</p>
<pre><code> @login_required(login_url='login')
def createInfringer(request):
customer=request.user.customer
form = InfringerForm(customer=customer)
if request.method == 'POST':
form = InfringerForm(customer, request.POST)
if form.is_valid():
form.save()
return redirect('infringer-list')
context ={'form': form}
return render (request, 'base/infringement_form.html', context)
</code></pre>
<p>forms.py</p>
<pre><code> class InfringerForm(ModelForm):
def __init__(self, customer, *args, **kwargs):
super(InfringerForm,self).__init__(*args, **kwargs)
self.fields['customer'].queryset = Customer.objects.filter(name=customer)
self.fields['status'].queryset = Status.objects.filter(customer=customer)
class Meta:
model = Infringer
fields = ['name', 'brand_name','status','customer']
</code></pre>
<p>UPDATE
suggestion below was added but it still doesn't save customer.</p>

74,438,322 | <p>So - if I try to access a writeable within a +page.js then it just returns empty.</p>
<pre class="lang-js prettyprint-override"><code>import { isAuthenticated, user } from '../../authstore';
export const load = async ({ fetch }) => {
console.log ('doing load')
console.log('is auth = ', isAuthenticated)
if (! isAuthenticated) {
throw redirect(302, '/');
}
return {test:''};
}
</code></pre>
<p>As you can see, I'm adding this to a +page.js to check logged in status and if not, redirecting them to the root.</p>
<p>However - isAuthenticated isn't accessible. Is this because it's running on the server rather than the client?</p>

74,438,324 | <p>I'm working through 99 scheme problems and I have a solution for P16 (Drop every N'th element from a list.) using recursion, but I'm trying to practice more functional methods. Is there a clean way to filter by index in mit-scheme?</p>
<pre><code>(display (drop '(a b c d e f g h i j k) 3)))
=> (a b d e g h k)
</code></pre>
<p>In Python I could use enumerate:</p>
<pre><code>import string
lst = list(string.ascii_lowercase[:11])
fltr = filter(lambda item: (item[0]+1)%3, enumerate(lst))
mp = map(lambda item: item[1], fltr)
print(list(mp))
=> ['a', 'b', 'd', 'e', 'g', 'h', 'j', 'k']
</code></pre>
<p>or list comprehensions</p>
<pre><code>print([value for index, value in enumerate(lst) if (index+1)%3])
=> ['a', 'b', 'd', 'e', 'g', 'h', 'j', 'k']
</code></pre>
<p>Thanks!</p>

74,438,362 | <p>I'm trying to figure out what I need to do in order to have lib/graphql recognise the mutations I have made.</p>
<p>I have an issue.tsx (which is a form). It imports:</p>
<pre><code>import {
IssueInput,
useUpdateIssueMutation,
useAllIssuesQuery,
useCreateIssueMutation,
useDeleteIssueMutation,
Issue as IssueGQLType,
} from "lib/graphql"
</code></pre>
<p>Other than IssueInput and Issue, I'm getting errors in my terminal that say these queries and mutations are not exported members.</p>
<p>However when I try to load the issue page in local host, I get an error that says:</p>
<blockquote>
<p>error - GraphQLError [Object]: Syntax Error: Expected Name, found
. It points to the line where Issue is imported.</p>
</blockquote>
<p>I made all of these queries and mutations in my resolver as follows:</p>
<pre><code>import { Arg, Mutation, Query, Resolver } from "type-graphql"
import { Issue } from "./issue.model"
import { IssueService } from "./issue.service"
import { IssueInput } from "./inputs/create.input"
import { Inject, Service } from "typedi"
import { UseAuth } from "../shared/middleware/UseAuth"
import { Role } from "@generated"
@Service()
@Resolver(() => Issue)
export default class IssueResolver {
@Inject(() => IssueService)
issueService: IssueService
@Query(() => [Issue])
async allIssues() {
return await this.issueService.getAllIssues()
}
@Query(() => [Issue])
async futureRiskIssues() {
return await this.issueService.getFutureRiskIssues()
}
@Query(() => Issue)
async issue(@Arg("id") id: string) {
return await this.issueService.getIssue(id)
}
@UseAuth([Role.ADMIN])
@Mutation(() => Issue)
async createIssue(@Arg("data") data: IssueInput) {
return await this.issueService.createIssue(data)
}
@UseAuth([Role.ADMIN])
@Mutation(() => Issue)
async deleteIssue(@Arg("id") id: string) {
return await this.issueService.deleteIssue(id)
}
@UseAuth([Role.ADMIN])
@Mutation(() => Issue)
async updateIssue(@Arg("id") id: string, @Arg("data") data: IssueInput) {
return await this.issueService.updateIssue(id, data)
}
}
</code></pre>
<p>I can also see from my graphql.tsx file, that these functions are recognised as follows:</p>
<pre><code>export type Mutation = {
__typename?: 'Mutation';
createIssue: Issue;
createUser: User;
deleteIssue: Issue;
destroyAccount: Scalars['Boolean'];
forgotPassword: Scalars['Boolean'];
getBulkSignedS3UrlForPut?: Maybe<Array<SignedResponse>>;
getSignedS3UrlForPut?: Maybe<SignedResponse>;
login: AuthResponse;
register: AuthResponse;
resetPassword: Scalars['Boolean'];
updateIssue: Issue;
updateMe: User;
};
export type MutationCreateUserArgs = {
data: UserCreateInput;
};
export type MutationDeleteIssueArgs = {
id: Scalars['String'];
};
export type MutationUpdateIssueArgs = {
data: IssueInput;
id: Scalars['String'];
};
</code></pre>
<p>I have run the codegen several times and can't think of anything else to try to force these mutations and queries to be recognised. Can anyone see a way to trouble shoot this?</p>
<p>My codegen.yml has:</p>
<pre><code>schema: http://localhost:5555/graphql
documents:
- "src/components/**/*.{ts,tsx}"
- "src/lib/**/*.{ts,tsx}"
- "src/pages/**/*.{ts,tsx}"
overwrite: true
generates:
src/lib/graphql.tsx:
config:
withMutationFn: false
addDocBlocks: false
scalars:
DateTime: string
plugins:
- add:
content: "/* eslint-disable */"
- typescript
- typescript-operations
- typescript-react-apollo
</code></pre>
<p>When I look at the mutations available on the authentication objects (that are provided with the [boilerplate app][1] that I am trying to use), I can see that there are mutations and queries that are differently represented in the lib/graphql file. I just can't figure out how to force the ones I write to be included in this way:</p>
<pre><code>export function useLoginMutation(baseOptions?: Apollo.MutationHookOptions<LoginMutation, LoginMutationVariables>) {
const options = {...defaultOptions, ...baseOptions}
return Apollo.useMutation<LoginMutation, LoginMutationVariables>(LoginDocument, options);
}
</code></pre>
<p>Instead, I get all of these things, but none of them look like the above and I can't figure out which one to import into my front end form so that I can make an entry in the database. None of them look like the queries or mutations I defined in my resolver</p>
<pre><code>export type IssueInput = {
description: Scalars['String'];
issueGroup: Scalars['String'];
title: Scalars['String'];
};
export type IssueListRelationFilter = {
every?: InputMaybe<IssueWhereInput>;
none?: InputMaybe<IssueWhereInput>;
some?: InputMaybe<IssueWhereInput>;
};
export type IssueRelationFilter = {
is?: InputMaybe<IssueWhereInput>;
isNot?: InputMaybe<IssueWhereInput>;
};
export type IssueWhereInput = {
AND?: InputMaybe<Array<IssueWhereInput>>;
NOT?: InputMaybe<Array<IssueWhereInput>>;
OR?: InputMaybe<Array<IssueWhereInput>>;
createdAt?: InputMaybe<DateTimeFilter>;
description?: InputMaybe<StringFilter>;
id?: InputMaybe<UuidFilter>;
issueGroup?: InputMaybe<IssueGroupRelationFilter>;
issueGroupId?: InputMaybe<UuidFilter>;
subscribers?: InputMaybe<UserIssueListRelationFilter>;
title?: InputMaybe<StringFilter>;
updatedAt?: InputMaybe<DateTimeFilter>;
};
export type IssueWhereUniqueInput = {
id?: InputMaybe<Scalars['String']>;
};
</code></pre>
<p>I do have this record in my graphql.tsx file:</p>
<pre><code>export type Mutation = {
__typename?: 'Mutation';
createIssue: Issue;
createIssueGroup: IssueGroup;
createUser: User;
deleteIssue: Issue;
deleteIssueGroup: IssueGroup;
destroyAccount: Scalars['Boolean'];
forgotPassword: Scalars['Boolean'];
getBulkSignedS3UrlForPut?: Maybe<Array<SignedResponse>>;
getSignedS3UrlForPut?: Maybe<SignedResponse>;
login: AuthResponse;
register: AuthResponse;
resetPassword: Scalars['Boolean'];
updateIssue: Issue;
updateIssueGroup: IssueGroup;
updateMe: User;
};
</code></pre>
<p>but I can't say: createIssueMutation as an import in my issue.tsx where I'm trying to make a form to use to post to the database.

Is there a proper way of tackling this issue or do I just have to get creative with how I format my data?</p>

74,438,416 | <p>I am new to Java and was trying to write code that would tell you how much change you would receive for a given amount of money (in minimum number of coins). For example <strong>$0.31</strong> would give <strong>1 quarters, 0 dimes, 1 nickels, 1 pennies</strong>.</p>
<p>I got to a point where my code seemed to work. However, while most values work, specifically any multiple of 0.41 doesn't work (ex. 0.41, 0.82 ...). For example <strong>$0.41</strong> results in <strong>1 quarters,
1 dimes, 1 nickels, 0 pennies</strong>, which only adds up to $0.40.</p>
<p>Here is my code:</p>
<pre><code>import java.util.Scanner;
public class Cash {
public static void main(String[] args){
Scanner scanner_obj = new Scanner(System.in);
System.out.print("Enter Amount: $");
double amount = Double.parseDouble(scanner_obj.nextLine());
double[] change = calc_Change(amount);
System.out.println(change[0] + " Quarters");
System.out.println(change[1] + " Dimes");
System.out.println(change[2] + " Nickels");
System.out.println(change[3] + " Pennies");
System.out.println(check_Change(amount, change));
}
public static double[] calc_Change(double amount){
double[] change = {0, 0, 0, 0};
while (amount >= 0.25){amount -= 0.25; change[0] += 1;}
while (amount >= 0.10){amount -= 0.10; change[1] += 1;}
while (amount >= 0.05){amount -= 0.05; change[2] += 1;}
while (amount >= 0.01){amount -= 0.01; change[3] += 1;}
return change;
}
public static boolean check_Change(double amount, double[] change){
double total = change[0]*0.25 + change[1]*0.10 + change[2]*0.05 + change[3]*0.01;
System.out.println(amount + " vs " + total);
return (amount == total);
}
}
</code></pre>
<p>I was using the check_Change function to check my results.</p>
<p>I don't know why this doesn't work and why it is only certain numbers.</p>

74,438,566 | <p>I have a dataframe (df) that has three columns (user, vector, and group name), the vector column with multiple comma-separated values in each row.</p>
<pre><code>df = pd.DataFrame({'user': ['user_1', 'user_2', 'user_3', 'user_4', 'user_5', 'user_6'], 'vector': [[1, 0, 2, 0], [1, 8, 0, 2],[6, 2, 0, 0], [5, 0, 2, 2], [3, 8, 0, 0],[6, 0, 0, 2]], 'group': ['A', 'B', 'C', 'B', 'A', 'A']})
</code></pre>
<p>I would like to calculate for each group, the sum of dimensions in all rows divided by the total number of rows for this group.</p>
<p>For example:
For group, A is <code>[(1+3+6)/3, (0+8+0)/3, (2+0+0)/3, (0+0+2)/3] = [3.3, 2.6, 0.6, 0.6]</code>.</p>
<p><a href="https://i.stack.imgur.com/hC0Kx.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/hC0Kx.png" alt="enter image description here" /></a></p>
<p>For group, B is <code>[(1+5)/2, (8+0)/2, (0+2)/2, (2+2)/2] = [3,4,1,2].</code></p>
<p>For group, C is <code>[6, 2, 0, 0]</code></p>
<p>So, the expected result is an array:</p>
<pre><code>group A: [3.3, 2.6, 0.6, 0.6]
group B: [3,4,1,2]
group C: [6, 2, 0, 0]

74,438,649 | <p>Need to prevent the main image on the product page from lazy loading.</p>
<p>The main product image is loaded in 'woocommerce/single-product/product-image.php'</p>

<p>Inside the function above, there is:</p>
<pre><code>// Add `loading` attribute.
if ( wp_lazy_loading_enabled( 'img', 'wp_get_attachment_image' ) ) {
$default_attr['loading'] = wp_get_loading_attr_default( 'wp_get_attachment_image' );
}
$attr = wp_parse_args( $attr, $default_attr );
// If the default value of `lazy` for the `loading` attribute is overridden
// to omit the attribute for this image, ensure it is not included.
if ( array_key_exists( 'loading', $attr ) && ! $attr['loading'] ) {
unset( $attr['loading'] );

<p>So clearly it's possible to not lazy load it, but I just don't fully understand how I can do this?</p>

74,438,656 | <p>I'm working on a school assignment. I am writing a program that utilizes <code>union</code>s to convert a given IP address in "192.168.1.10" format into its 32-bit single value, two 16-bit values, and four 8-bit values.</p>
<p>I'm having trouble with implementing my <code>struct</code>s and <code>union</code>s appropriately, and am looking for insight on the subject. To my understanding, <code>union</code>s point to the same location as the referenced <code>struct</code>, but can look at specified pieces.</p>
<p>Any examples showing how a <code>struct</code> with four 8-bit values and a <code>union</code> can be used together would help. Also, any articles or books that might help me would also be appreciated.</p>
<p>Below is the assignment outline:</p>
<blockquote>
<p>Create a program that manages an IP address. Allow the user to enter the IP address as four 8 bit unsigned integer values (just use 4 sequential CIN statements). The program should output the IP address upon the users request as any of the following. As a single 32 bit unsigned integer value, or as four 8 bit unsigned integer values, or as 32 individual bit values which can be requested as a single bit by the user (by entering an integer 0 to 31). Or as all 32 bits assigned into 2 variable sized groups (host group and network group) and outputted as 2 unsigned integer values from 1 bit to 31 bits each.</p>
</blockquote>
<p>I was going to <code>cin</code> to <code>int pt1,pt2,pt3,pt4</code> and assign them to the <code>IP_Adress.pt1</code>, .... etc.</p>
<pre><code>struct IP_Adress {
unsigned int pt1 : 8;
unsigned int pt2 : 8;
unsigned int pt3 : 8;
unsigned int pt4 : 8;
};
</code></pre>
<p>I have not gotten anything to work appropriately yet. I think I am lacking a true understanding of the implementation of <code>union</code>s.</p>

<p>I want to compare the standard deviations of each column, so obviously I need to remove the NaNs. I want to do this column-wise though, so that I don't just remove all rows where one value is NaN because I'll lose a lot of data. What's the best way to do this? I have a lot of columns, otherwise I would just make a numpy array representing each column.</p>

74,438,687 | <p>I'm trying to add a button to a customization screen in Acumatica that will run a small JavaScript function when clicked.</p>
<p>I am able to type the function inside a <strong>JavaScript control</strong>, which will be called from the button's <strong>Click</strong> or <strong>MouseDown</strong> events. I can also directly type the function into any of these 2 button events, without the need of the JavaScript control.</p>
<p>Using a basic <code>alert("test");</code> for testing, I can confirm the code runs, with any of the 2 methods I described above.</p>
<h3>The problem:</h3>
<p>Clicking on the button doesn't run the code. Instead, the message pops up right after the screen loads, and it actually does it 2 times, so it seems the function runs automatically twice on screen load.</p>
<ul>
<li>Is this possibly a bug? or am I doing something wrong?</li>
<li>Is there a "correct" way or a specific set of steps to follow in order to include JavaScript code into a Customization Screen?</li>
</ul>
<p><em><strong>Notes:</strong></em></p>
<ul>
<li><em>Currently testing on Acumatica 2022 R1.</em></li>
<li><em>I have tested this prior to and after publishing the screen, getting the same results.</em></li>
</ul>

74,438,689 | <p>I was just wondering if anyone can help me with this problem.</p>
<p>I have two tables - Table 1 & Table 2.</p>
<p>What I'm trying to do is to find 2 timestamps before and after 'date' from Table 1, so everything highlighted in pink in Table 2.</p>
<p>How can I do this in Microsoft SQL Server? ideally without using CTE. Unfortunately, CTE is not supported by Tableau.</p>
<p>Thank you in advance.</p>

74,438,697 | <p>I have an array that looks like this:</p>
<pre class="lang-js prettyprint-override"><code>const arr = [
{
parent: 'A',
children: ['B'],
},
{
parent: 'B',
children: ['C'],
},
{
parent: 'C',
children: ['D']
}];
</code></pre>
<p>and I want to create a function that will take this array and result in the following object:</p>
<pre class="lang-js prettyprint-override"><code>const result = {
parent: 'A',
children: [{
parent: 'B',
children: [{
parent: 'C',
children: [{
parent: 'D',
children: []
}]
}]
}]
};
</code></pre>
<p>so the result type would look like:</p>
<pre class="lang-js prettyprint-override"><code>type Result = {
parent: string;
children: Result[];
};
</code></pre>
<p>What I've tried so far:</p>
<pre class="lang-js prettyprint-override"><code>type TInput = {
parent: string;
children: string[];
};
type Result = {
parent: string;
children: Result[];
};
// can assume we know initial parent is 'A'
const fn = (parent: string, inputArr: TInput[]) => {
const result: TResult[] = [];
let newParent: string[] = [];
while (newParent.length !== 0) {
const index = inputArr.findIndex(
(input) => input.parent === parent
);
result.push({
parent: inputArr[index].parent,
children: [], // need to populate on next pass?
});
newParent = inputArr[index].children;
}
return result;
};
</code></pre>
<p>I don't know how many objects will be in the input array, but can assume first object is known to be initial parent/child ('A' in the example). Any help much appreciated.
Thanks</p>

<p>This solution is for <a href="https://leetcode.com/problems/group-anagrams/" rel="nofollow noreferrer">Group Anagrams</a> on Leetcode. I'm just using XCode to practice writing out all the code needed, instead of using what Leetcode gives.</p>
<p>My issue comes when calling and trying to print the <code>groupAna()</code> function in class <code>Solution</code>. I believe the error is telling me what I want to print isn't something you can print, but I have no idea if that's entirely correct.</p>
<p>I'm ultimately trying to print each string inside its respective <code>vector</code>. What's commented out was a workaround that gives me what I want, but it doesn't show each word in a <code>vector</code>, so how can I tell if it's in the <code>vector</code> it's suppose to be in, other than it being in the correct order?</p>
<p>Output is <code>bat tan nat eat tea ate</code></p>

74,438,797 | <p>So i'am working around an exercise that should be a very basic and easy function</p>
<p>Whish takes as argument a string and a list and should return None if there string is not in the list and return some list where the string has been removed from the list. This is an 2015 exam set i am practising and using List. functions is not allowed</p>
<p>So far i've managed to come up with this</p>
<pre><code>let rec fromShelf bs ls =
match ls with
|[] -> None
|h::tl when h=bs -> Some tl
|h::tl -> Some (h::Option.get(fromShelf bs tl))
</code></pre>
<p>However this loop will run forever in case the string is not in the list and i'am suppose to preserve the list while iterating so i am really stuck.. would appreciate any help or hints.</p>

74,438,823 | <p>I am unable to get a connection working using <a href="https://github.com/aws-samples/cloud9-to-power-vscode-blog/blob/main/scripts/ssm-proxy.sh" rel="nofollow noreferrer">this ssm-proxy.sh script</a> to remote connect to AWS Cloud9 from Visual Studio Code. I am following <a href="https://aws.amazon.com/blogs/architecture/field-notes-use-aws-cloud9-to-power-your-visual-studio-code-ide/" rel="nofollow noreferrer">this article</a> on how to use AWS Cloud9 to power my Visual Studio Code IDE. I am able to connect by SSH but not when invoking the proxy script.</p>
<p>This works:</p>
<pre><code>Host test1
HostName xx.xxx.xxx.xx
User ec2-user
IdentityFile ~/.ssh/vscloud9
</code></pre>
<p>However, this doesn't:</p>
<pre><code>Host cloud9
IdentityFile ~/.ssh/vscloud9
User ec2-user
HostName i-xxxxxxxxxxxxx
ProxyCommand sh -c "~/.ssh/ssm-proxy.sh %h %p"
</code></pre>
<p>Using the AWS CLI I have configured the default named profile with an access key and secret and output of json. Despite it being bad practice, the access key and secret is for the root user so permissions are not causing an issue. This is then detailed in ssm-proxy.sh:</p>
<pre><code>AWS_PROFILE='default'
AWS_REGION='eu-west-2'
MAX_ITERATION=5
SLEEP_DURATION=5
</code></pre>
<p>SSH from anywhere is enabled in security groups.</p>
<p>Since plain SSH works with the vscloud9 key, the key pair isn't the issue. I am thinking that the problem is either the AWS profile or the ssm-proxy.sh script itself.</p>
<p>I am using the Remote - SSH VSCode extension.</p>
<p>I need to get this working so I'm wondering if anyone has any idea why this wouldn't work?</p>

74,438,840 | <p>The Excel formula XMATCH has a third argument that returns a value if the value being tested is EITHER greater OR less than the list of values. I need it to return a numeric value in all cases - Less than the minimum (7 in the example below), within the values (1-7 in the example) or greater than the maximum (1 in the example) .</p>
<p>Example

74,438,879 | <p>I have an iframe that changes src pages when the page would normally switch to another page so that my main JS file can continue running in the background. For the first page, the one defined in the HTML src for the Iframe, I can access the inner document just fine by using iframe.contentDocument.</p>
<p>However, when I change the src, the contentDocument does not change with it, and I cannot access the Iframe's document in the JS at all.</p>
<p>So is there any way to access the new document of an Iframe after changing its source in JS? Or is there an easier alternative for the way I am doing things?
Thanks.</p>
<p>How I've tried:</p>
<pre><code>iframe.src = "pages/home/home.html"
innerDoc = iframe.contentDocument || iframe.contentWindow.document
</code></pre>
<p>and the innerDoc does not change from the original page.
I've even tried making an entirely new Iframe that never had the original page as its src</p>
<pre><code>document.body.removeChild(iframe)
let i = document.createElement('iframe')
i.src='pages/home/home.html'
document.body.appendChild(i)
innerDoc = i.contentDocument || i.contentWindow.document
</code></pre>
<p>This just makes innerDoc an empty HTML document with an empty head and body.</p>

74,438,887 | <p>I need to parse the line similar to the:</p>
<pre><code>'''Object{identifier='d6e461c5-fd55-42cb-b3e8-40072670fd0f', name='some_name2', identifier='d6e461c5-fd55-42cb-b3e8-40072670fd0f', name='some_name3', value=value_without_quotes}'''
</code></pre>
<p>The line is much longer, but the pattern is the same.</p>
<p>Basically, I need a list (or dict) with key, value. Something like:</p>
<pre><code>["'identifier', ''d6e461c5-fd55-42cb-b3e8-40072670fd0f''", "'name', ''some_name2''", "'identifier', ''d6e461c5-fd55-42cb-b3e8-40072670fd0f''", "'name', ''some_name3''", "'value', 'value_without_quotes'"]
</code></pre>
<p>I ended up with the following regular expression:</p>
<pre><code>r'Object{(+?)=(+?)}'
</code></pre>
<p>It works only if I need the only one object. I'm expecting something like</p>
<pre><code>((+?)=(+?),)+
</code></pre>
<p>to be worked, but it's not.
For example,</p>
<pre><code>re.match(r'Object{((.+?)=(.+?),?)+}', line3).groups()
</code></pre>
<p>Gives me:</p>
<pre><code>("some_name3', value=value_without_quotes", "some_name3', value", 'value_without_quotes')
</code></pre>
<p>As you can see 'value=value_without_quotes' appeared. r'Object{(([^=]+?)=(.+?),?)+}' doesn't work also.</p>
<p>So the question is how to repeat the above in sequence? The thing is that I don't if the value contains quotes, symbols or digits.</p>
<p>Thank you</p>

74,438,906 | <p>I have a dataset where I would like to remove all rows where the date is 4/1/2022 within a column in my dataset. The Date column is datetime64ns</p>
<p><strong>Data</strong></p>
<pre><code>ID Date
AA 1/1/2022

<p><strong>Desired</strong></p>

<p><strong>Doing</strong></p>
<pre><code> new = df[df['Date'].str.contains('4/1/2022')==False]
</code></pre>
<p>However, this is not a string, it is datetime. This is not removing the rows at all. I am still researching. Any suggestion is appreciated.</p>

74,438,930 | <p>I am very very new to Swift programming and I am growing to dislike it very much. I am not grasping it aa easily as other languages.</p>
<p>I have a project I am working on and I cannot figure out what is wrong or why its isn't working.</p>
<p>In one view, I have a table view that has a cell. I am using an array to store all the values that I want to be stored in the corresponding elements in the table view.</p>
<p>When the user clicks on an individual cell in the table view, it will bring them to another view displaying other elements of the movie (runtime, image, director and year).</p>
<p>I have a template that I am using to code this and I think I have done everything correctly, but when I run the app, nothing shows.</p>
<p>I just want the table cells to show on startup, when I run the app. I can even troubleshoot myself if I can just have the table cells show.</p>
<p>Since I am so new to this language and XCode, I am having trouble navigating the IDE to find my issues. On top of much I am already struggling with Swift.</p>
<p>I could really use the help, if possible!</p>
<p>Here is all the code I have done:</p>
<pre><code> import UIKit
class ViewController: UIViewController,
UITableViewDelegate,
UITableViewDataSource {
let movieList = ["Step Brothers", "Pulp Fiction", "Ali", "Harry Potter"]
let yearList = ["2008", "1994", "2001", "2001"]
let images = ["step_brothers", "pulp_fiction", "ali", "harry_potter3"]
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return movieList.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let tempCell: TableViewCell = tableView.dequeueReusableCell(withIdentifier:
"cell") as! TableViewCell
tempCell.movieTitleLabel.text = movieList[indexPath.row]
tempCell.movieYearLabel.text = yearList[indexPath.row]
tempCell.movieImage.image = UIImage(named: images[indexPath.row] + ".jpeg")
return tempCell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let detailVC:MovieDetailViewController = self.storyboard?.instantiateViewController(withIdentifier: "MovieDetailViewController") as! MovieDetailViewController
// assign the values to the local variable declared in ProductDetailViewController Class
detailVC.movieImage = UIImage(named: images[indexPath.row] + ".jpeg")!
// make it navigate to ProductDetailViewController
self.navigationController?.pushViewController(detailVC, animated: true)
}
}
</code></pre>
<p>This is for the individual cell in the table view:</p>
<pre><code>import UIKit
class TableViewCell: UITableViewCell {
@IBOutlet weak var movieTitleLabel: UILabel!
@IBOutlet weak var movieYearLabel: UILabel!
@IBOutlet weak var movieImage: UIImageView!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
</code></pre>
<p>This is the MovieDetailViewController:</p>
<pre><code>class MovieDetailViewController: UIViewController {
@IBOutlet weak var movieDetailImage: UIImageView!
@IBOutlet weak var runtimeLabel: UILabel!
@IBOutlet weak var yearDetailLabel: UILabel!
@IBOutlet weak var directorDetailLabel: UILabel!
var runtime: String! // holds the product name
var year: String! // holds the price
var movieImage: UIImage! // holds the product image
var director: String!
override func viewDidLoad() {
super.viewDidLoad()
movieDetailImage.image = movieImage
runtimeLabel.text = runtime
yearDetailLabel.text = year
directorDetailLabel.text = director
// Do any additional setup after loading the view.
}
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// Get the new view controller using segue.destination.
// Pass the selected object to the new view controller.
}
*/
}
</code></pre>
<p>This is the error shown in the terminal, but there are no actual errors in the code:</p>
<p><code>2022-11-14 17:39:28.232645-0500 Exercise01[25678:1217794] [Storyboard] Unable to find method -[(null) TableViewCell] 2022-11-14 17:39:28.259975-0500 Exercise01[25678:1217794] [Assert] UINavigationBar decoded as unlocked for UINavigationController, or navigationBar delegate set up incorrectly.

<p>I can throw in the AppDelegate and SceneDelegate if you need it, just let me know.</p>
<p>Thank you everyone, again! I greatly appreciate the help!</p>

d('key') = arr

74,438,995 | <p>I installed successfully Odoo 16 on Ubuntu 22. (Yenthe script) When I run Odoo directly with the IP address on port 8069 everything functions. But when I run it with a domain name with a server block several things happen: The initial website generation gets stuck in an endless loop. After letting it run for a long time when I refresh the screen the website is created but I cannot edit it. I can click on the frontend editor button in the top left area but the edit mode does not appear. The editible area changes into dark grey with a large circle circling endlessly.
When I alternate the same app wit the Ip number it works without a problem.</p>
<p>I am using cloudflare.</p>
<p>First I suspected the server block but I have been using suggested variations but no changes. The error log does not show obvious errors.</p>
<p>Does anyone out there have a similar experience? Are there solutions?</p>

74,439,008 | <p>I was working with VS Code and everything was fine, now out of nowhere there is a problem with the intellisense caused by Omnisharp in my opinion. I'm with Macbook Air M1 (2020) with Ventura 13.0.1, also I'm with the latest .Net SDK 6.0.402. The intellisense is not working at all, I reinstalled the C# extension from Microsoft, but it didn't fix the problem. What can cause this issue ?!</p>

74,439,019 | <p>I have a dataframe with rows as dictionaries as below:</p>
<pre><code>Col1 A B
{'A': 1, 'B': 23} apple carrot
{'A': 3, 'B': 35} banana spinach
</code></pre>
<p>I want to expand Col1 such that the dataframe looks like this:</p>
<pre><code>Col1.A Col2.B A B
1 23 apple carrot
3 35 banana spinach
</code></pre>
<p>How can I do this using pandas in python? Please let me know if there is any other way as well.</p>
<p>I tried using pd.explode but the new column names are being duplicated. How to avoid this?</p>

<p>On every page on my website, I have one common.js file for stuff that is always needed on every single page. And then I have one js file specifically for that page.</p>
<p>My problem is that variables declared in the common.js file needs to be accessed in the second js file as well, but I am running into some issues because the script is not waiting for the data variable to be declared, and it is not allowed to use await in the top level of the script.</p>
<pre><code>// common.js
let data;
async function get_data() {
data = await fetch('/get-data').then(res => res.json())
console.log(data) // works!!!
}
get_data();
console.log(data) // does not work!!!
</code></pre>
<pre><code>// homepage.js
console.log(data) // does not work!!!
</code></pre>
<p>So what I am asking is how can I make the two <code>console.log(data)</code> calls that aren't working, work!</p>

74,439,102 | <p>I don't speak Russian, so I'm having trouble validating whether the months are correctly spelled, etc. To be honest, I'm not fully sure that my input is in Russian (Russian is the language detected by Google translate)</p>
<p>I have some code in Kotlin which does a best-effort to parse dates specified in various formats and languages. I'm struggling with parsing Russian dates, however. Here's the relevant part of my code:</p>
<pre class="lang-kotlin prettyprint-override"><code>sequenceOf(
"ru-RU", // Russian
"sr", // Serbian
).forEach {
val format = DateTimeFormatter.ofPattern("d MMM. yyyy")
.withLocale(Locale.forLanguageTag(it))
try {
return listOf(LocalDate.parse(dateString, format))
} catch (e: Exception) {
//Ignore and move on
}
}
</code></pre>
<p>This code correctly parses <code>"27 апр. 2018"</code> and <code>"24 мая. 2013"</code>, but fails on <code>"28 фев. 2019"</code>.</p>
<p>What's special about <code>"28 фев. 2019"</code> and/or how can I parse this value correctly?</p>
<p>If you provide answers in Java, I can translate it to Kotlin fairly easily.</p>
<hr />
<p><strong>EDIT</strong>: Here's an SSCCE in Kotlin:</p>
<pre class="lang-kotlin prettyprint-override"><code>import java.time.LocalDate
import java.time.format.DateTimeFormatter
import java.util.*
println("System.getProperty - " + System.getProperty("java.version"));
println("Runtime.version - " + Runtime.version());
val dateString = "28 фев. 2019"
sequenceOf(
"ru-RU", // Russian
"sr", // Serbian
).forEach {
val format = DateTimeFormatter.ofPattern("d MMM. yyyy")
.withLocale(Locale.forLanguageTag(it))
try {
println("Parse successful - " + LocalDate.parse(dateString, format))
} catch (e: Exception) {
println("Parse failed - " + e)
}
}
</code></pre>
<p>Output on my system:</p>
<pre><code>System.getProperty - 17.0.4.1
Runtime.version - 17.0.4.1+7-b469.62
Parse failed - java.time.format.DateTimeParseException: Text '28 фев. 2019' could not be parsed at index 3
Parse failed - java.time.format.DateTimeParseException: Text '28 фев. 2019' could not be parsed at index 3
</code></pre>

74,439,175 | <p><strong>Situation:</strong></p>
<p>C++ app developed with Visual Studio 2022 dies in Release mode only when debugger is detached. Now, while I may know the typical scenarios where this might be happening the code base is too immense for me to do any per-line code reviews. So, I set Windbg as post-mortem debugger in hopes of finding where it dies.</p>
<p>Now, shed some light onto me, please.</p>
<p><strong>Question</strong>:</p>
<p>How do I see the exact reason why a fatal exception was thrown? Any way to browse through the recent exceptions?</p>
<p><strong>Discussion</strong></p>
<p>The funny thing in my case is that, this multi-threaded app, after the exception is caught by WinDbg launching in post-mortem mode.. the app continues to run.... I need to pause execution.. so I wonder what throws the exception.. and why does the app continue code execution after it was caught by WindDBG (without WindDBG set as post-mortem debugger and thus without it catching the exception - the app simply dies).</p>
<p><strong>Update:</strong></p>
<p>The only suspicious thing I am shown by WinDbg right after it is invoked is:</p>
<blockquote>
<p>WARNING: Continuing a non-continuable exception</p>

74,439,197 | <p>I have this dict that was provided by ansible_facts</p>
<pre class="lang-yaml prettyprint-override"><code> ansible_facts.lvm.lvs:
lv-something-1:
size_g: '70.00'
vg: blockchains
lv-something2-2:
size_g: '45.00'
vg: blockchains
lv-something3-3:
size_g: '250.00'
vg: blockchains
lv-something4-4:
size_g: '4610.00'
vg: blockchains
lv-something5-5:
size_g: '500.00'
vg: blockchains
lv-something6-6:
size_g: '25.00'
vg: blockchains
lvthinpool:
size_g: '10666.11'
vg: blockchains
</code></pre>
<p>First, I tried a lot to remove the <code>thinpool</code> item, but I was not successful, I tried to convert this dict to a list, tried to use <code>reject, rejectattr</code>, but they give just the names.. like this
I even tried to create two lists and make a concat but no success, lol</p>
<pre class="lang-yaml prettyprint-override"><code> ansible_facts.lvm.lvs | reject('search', 'thinpool'):
- lv-something-1
- lv-something2-2
- lv-something3-3
- lv-something4-4
- lv-something5-5
- lv-something6-6
</code></pre>
<p>but I wanna catch the size of my volumes.. I wanna just remove <code>lvthinpool</code> to the dict, there is a way? and after that I will catch all size_g and I'll add up all your value</p>
<p>my dict expect output is:</p>
<pre class="lang-yaml prettyprint-override"><code> ansible_facts.lvm.lvs:
lv-something-1:
size_g: '70.00'
vg: blockchains
lv-something2-2:
size_g: '45.00'
vg: blockchains
lv-something3-3:
size_g: '250.00'
vg: blockchains
lv-something4-4:
size_g: '4610.00'
vg: blockchains
lv-something5-5:
size_g: '500.00'
vg: blockchains
lv-something6-6:
size_g: '25.00'
vg: blockchains
</code></pre>
<p>I've be tried to use set_fact to convert this dict to a list and manipulate date with <code>reject</code> or <code>rejectattr</code>, then create two dict, and tried to union these values.. I've be tried to put the content to a file and delete it using regex with the <code>linefile</code> module</p>

74,439,199 | <p>I have made a list of all number from 0 to 500 and then I am looking for all number that end with a certain integer. The thing is I don't under stand how its working.</p>
<p>I am new to coding so don't know what to expect here or how it is working.</p>
<pre><code>x = 0
y = []
while x <= 500:
y.append(x)
x = x + 1
a = 0
b = []
c = 0
# if i remove c from this or change c from 0 to 1 or any other number it just appends with that value
# but if c is as i have it, it some how appends the list with the values i am pulling with my if statment
while a <= 500:
if int(repr(y[a])[-1]) == 0:
b.append(c)
a = a + 1
c = c + 1
print(len(b))
print(b)

<p>This results in a index out of range, -1. I understand why this is,that is not the issue, but when I tweak it by having the control of the for loop be i<msg.length()-1, it works but does not print the last letter. I also tried changing i to start at 1, but that cut off the first letter. Just not sure how to get the whole message with no error. Thanks!</p>

<p>I still want the bottom navigation bar to remain the same length, but I want to add some padding in the container to the left to shift the cards over to the right a bit. I have the following code in my <code>MainActivity.kt</code> right now:</p>
<pre><code>WindowCompat.setDecorFitsSystemWindows(window, false)
ViewCompat.setOnApplyWindowInsetsListener(binding.root) { view, windowInsets ->
val insets = windowInsets.getInsets(WindowInsetsCompat.Type.systemBars())
view.updateLayoutParams<ViewGroup.MarginLayoutParams> {
topMargin = insets.top
}
binding.bottomNavigationView.updatePadding(bottom = insets.bottom)
WindowInsetsCompat.CONSUMED
}

<p>My <code>activity_main.xml</code> is composed of a <code>ConstraintLayout</code> that encloses two elements: <code>BottomNavigationView</code> and <code>FragmentContainerView</code>.</p>

74,439,263 | <p>So i am trying to build this website and as i go on i decided to use a bootstrap carousel, i already had a dropdown button in the navbar and a collapse menu when on smaller viewports and it all worked fine, but when i was implementing the carousel it had a delay between images. It was almost like a white page between them and i wasnt sure if my website was simply slow or if it was a feature of the carousel but since the other features worked fine then i doubted it was the website speed problem, also it has almost no code whatsoever.
So i had a bunch of script codes for bootstrap css and js and i decided to delete them all and put simply the 2 that are on the official bootstrap website and since then not just the carousel problem persists (the huge delay between images with a blank white space) and also the other features stoped working. Can someone help me implement bootstrap correctly?</p>
<p>heres the full code:</p>

74,439,269 | <p>I'm working in Google Sheets and am trying to find a more elegant way to return a value if a number in a referenced cell falls between two other values in the table. For example:</p>
<p><a href="https://i.stack.imgur.com/0cQlN.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/0cQlN.jpg" alt="Min Max and Return Values" /></a></p>
<p>In this case elsewhere I would like to show the return value based on the value from another cell. Such as:</p>
<p><a href="https://i.stack.imgur.com/YbODa.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/YbODa.jpg" alt="Example Data" /></a></p>
<p>I could do a long IF statement but would prefer something that I can expand more readily if we update the columns.</p>

74,439,284 | <p>I have a nested list that has certain elements with an [x] at the beginning. I want the function to remove those elements and move them to the last list in <code>list1</code> (at index 2). But it should remove the [x] from it before placing it in the last list. It should also count how many were removed from each list.</p>
<p>For example:</p>
<pre class="lang-py prettyprint-override"><code>list1 = [['[x]homework', '[x]eat','stretch'], ['[x]final', 'school'], ['sleep','midterm']
# After:
list1 = [['stretch'], ['school'], ['sleep','midterm', 'homework', 'eat', 'final']]
# Output:
# 2 removed from 1st list
# 1 removed from 2nd list

74,439,314 | <p>I need to check when a new process with a new visible main window handle is started (as the mouse hook of my app is lost on some applications and is restored only on a short internal restart).</p>
<p>I have tried to use <code>EnumWindows</code> and <code>EnumDesktopWindows</code> but those give me many many windows and child windows I do not need. I only need the visible main window handles. Therefore (and to find out if they are belonging to a new process) I decided to directly check the processes within an own update-check-thread. But this approach (as well as to permanently check EnumWindows) is extremely cpu consuming (1-3 % at Ryzen 5600X) and in my opinion, completely overblown.</p>
<p>Therefore I'd like to know if there is any other, slick approach to find out whenever any new process is started or window is opened to only execute the check when it is necessary.</p>

74,439,329 | <p>Basically I just want to change nested dictionaries but in my code I change multiple sublevel dictionaries at once.</p>
<p>So I have a nested dictionary which looks this way</p>
<pre><code>d1 = {'a': {0: [1,2], 1: [1,2]}, 'b': {0: [1,2], 1: [1,2]}}
</code></pre>
<p>Then I want to add an entry</p>
<pre><code>d1['a'][2] = [2,2]
</code></pre>
<p>And then I get what I want</p>
<pre><code>{'a': {0: [1, 2], 1: [1, 2], 2: [2, 2]}, 'b': {0: [1, 2], 1: [1, 2]}}
</code></pre>
<p>But when I want to create my dictionary like this (and I need it that way, because my dict has to have different lengths and so on)</p>
<pre><code>d2 = dict.fromkeys(['a','b'], dict.fromkeys([0,1], [1,2]))
</code></pre>
<p>I will get</p>
<pre><code>{'a': {0: [1, 2], 1: [1, 2], 2: [2, 2]}, 'b': {0: [1, 2], 1: [1, 2], 2: [2, 2]}}
</code></pre>
<p>so it will add the new dictionary entry to both lower level dictionaries. Why does it do this and how can I prevent this? I tried now a lot of stuff but I cant manage to solve this... Maybe you can help?</p>

74,439,336 | <p>I have a service that subscribes to an observable field of a dependency in the constructor. I am trying to write unit tests for this service, and in doing so, am trying to ignore the subscription to that observable. In other words, for some of these tests, I never want to emit a value, as I'm testing an unrelated function. How can I create a mock/spy of my service that simply does nothing with that observable?</p>
<p><strong>Service</strong></p>
<pre><code>export class MyService {
constructor(private authService: AuthService) {
this.authService.configure();
this.authService.events.subscribe(async (event) => {
await this.authService.refreshToken();
});
}
</code></pre>
<p><strong>AuthService dependency</strong></p>
<p>This is a snippet of the 3rd party service that my service depends on.</p>
<pre><code>export declare class AuthService implements OnDestroy {
events: Observable<Event>;
// ... other fields/functions
}
</code></pre>
<p><strong>Spec</strong></p>
<pre><code>describe('MyService', () => {
let authServiceSpy: jasmine.SpyObj<AuthService>;
beforeEach(() => {
authServiceSpy = jasmine.createSpyObj<AuthService>(
['configure', 'refreshToken'],
{
get events() { return defer(() => Promise.resolve(new Event('some_event'))); }
}
);
TestBed.configureTestingModule({});
});
it('should create service and configure authService', () => {
const myService = new myService(authServiceSpy);
expect(myService).toBeTruthy();
expect(authServiceSpy.configure).toHaveBeenCalledOnce();
});
});
</code></pre>
<p>Whenever I run this test, the expectation is met but it also runs the callback in the observable subscription, and I haven't mocked the <code>refreshToken</code> call (and don't want to have to).</p>

74,439,423 | <p>I've seen a lot of times code like this:</p>
<pre class="lang-scala prettyprint-override"><code>...
val aString: String = someFunctionDataReturnsAString()
...
if (someCondition) Some(aString)
else
...
</code></pre>
<p>Is it right to create a new <code>Option</code> using <code>Some(aString)</code>?
What if for some reason turns out the value of <code>aString</code> is <code>null</code>?
Wouldn't be good replacing the <code>if</code> sentence with:</p>
<pre class="lang-scala prettyprint-override"><code>if (someCondition) Option(aString)
</code></pre>
<p>Because:</p>
<pre class="lang-scala prettyprint-override"><code>val a = Some("hello")
val b: String = null
val c = Some(b)
val d = Option(b)
println(a)
println(c)
println(d)
</code></pre>
<p>Will print in the console:</p>
<pre><code>Some(hello)
Some(null)
None
</code></pre>
<p>Looks like a better idea to use <code>Option</code> when passing a string as parameter, so in case the string is <code>null</code> the value of the <code>Option</code> will be <code>None</code>.</p>
<p>I've seen code to be reviewed and I think with cases like this a comment should be added asking for replacing <code>Some(aString)</code> with <code>Option(aString)</code>.</p>

<p>This script only allows you to calculate an approximate date, as it does not take into account the exact number of days in each month or leap years.
I would like her to calculate the exact date of birth but I have no idea how to do that, I've racked my brains and searched the internet but nothing.
Any light?</p>

74,439,443 | <p>I am trying to upload a CSV file to my database in laravel. But my CSV file is pretty big, I almost have 500 million rows that I want to import. (I am using Maatwebsite to do this)</p>
<p>And when I try to import it I am getting:</p>
<pre><code>Maximum execution time of 300 seconds exceeded
</code></pre>
<p>As you can see I already changed the "max_input_time" in the php.init file. 300 seconds would be enough because datagrip takes only 3 minutes. And even if it would take longer in laravel there has to be another way than increasing the "max_input_time"</p>
<p>this is the code that's converting the data in a model and evantually putting it in de database:</p>
<pre><code>public function model(array $row)
{
return new DutchPostalcode([
'postalcode' => $row['PostcodeID'],
'street' => $row['Straat'],
'place' => $row['Plaats'],
'government' => $row['Gemeente'],
'province' => $row['Provincie'],
'latitude' => $row['Latitude'],
'longtitude' => $row['Longitude'],
]);
}
</code></pre>
<p>this is my controller:</p>
<pre><code>public function writeDutchPostalCodes(){
Excel::import(new DutchPostalcodes, 'C:\Users\Moeme\Documents\Projects\ahmo apps\Apps\freshness\Freshness - be\FreshnessBE\resources\postalcodes\postcodetabel_1.csv');
}
</code></pre>

<p>Is it possible to make it so the blue box only adds to the counter the first time it is pressed and then not again after that while still retaining the ability to press the boxes to make them visible/invisible?</p>

74,439,490 | <p>I'm new to Haskell and I'm currently trying to solve a little problem.</p>
<p>I want to create a function <code>occurrences</code> that is defined as such:</p>
<pre><code>occurrences:: Int -> String -> [[(Char, Int)]]
</code></pre>
<p>The function accepts an Int and String as its parameters; where Int represents the number of occurrence lists to be printed. The number of occurrences for each character should be sorted in descending order.</p>
<p>For example, <code>occurrences 2 'hi'</code> should return <code>[[('h', 1), ('i', 1)], [('h', 1), ('i', 1)]]</code> and <code>occurrences 3 'foo'</code> would return <code>[[('o', 2), ('f', 1)], [('o', 2), ('f', 1)], [('o', 2), ('f', 1)]]</code></p>
<p>So far I've added the below as part of my implementation for the occurrences function.</p>
<pre><code>occurrences str = map (\x -> [(head x, length x)]) $ group $ sort str
</code></pre>
<p>But this just prints <code>[[('h',1)],[('i',1)]]</code> rather than <code>[[('h', 1), ('i', 1)]]</code> and I'm not sure how to return <code>n</code> number of lists according to the input as I'm new to Haskell.</p>
<p>Can I get help on this please?</p>

74,439,491 | <p>I have a sample dataframe:</p>
<pre><code>| ID | SampleColumn1| SampleColumn2 | SampleColumn3 |
|:-- |:------------:| ------------ :| ------------ |
| 1 |sample Apple | sample Cherry |sample Lime |
| 2 |sample Cherry | sample lemon | sample Grape |
</code></pre>
<p>I would like to create a new DataFrame based off of this initial dataframe. Should one of several values in a list [Apple, Lime, Cherry] be in any of the columns for a row, it would appear as a 1 in the new dataframe for its column. In this case, the output should be:</p>
<pre><code>| ID | Apple | Lime | Cherry |
| 1 | 1 | 1 | 1 |
| 2 | 0 | 0 | 1 |
</code></pre>
<p>Currently I have tried in going about in using the find function for a string, transforming a series into a string for each row then using an if condition if the value has returned and equals the column name of the new dataframe. I am getting a logic error in this regard.</p>

<p>I tried all these and it's working fine. But I still want to see P1, P2 , ...etc instead of 1, 2,3.</p>
<p>Note: I call P1,P2, ...etc genrate names; maybe there is a better way to call this, but I just make it simple for better understanding</p>
<pre><code>expected results will be

74,439,568 | <p>I have been doing a bit of brushing up on my Linear Algebra basics and figured a fun way to do so would be with code. I am trying to create a function that performs Vector addition given two vectors of different lengths. For example if we have two vectors v1 = 0, 7, 3 and v2 = 1, 2, 4 our sum would be 1, 9, 7. My end goal is to be able to create a function that accepts n number of vectors of any numeric type and perform traditional vector addition on them.</p>
<p>So far I am able to naively do so by just traversing the first vector and adding each element to the corresponding element of second vector.</p>
<pre><code>int main() {
// create vectors
std::vector<int> v1 = {0, 7, 3, 4};
std::vector<int> v2 = {1, 2, 4, 1, 6};
int i = 0;
// iterate over v1 adding to the corresponding element in v2
for (i; i < v1.size(); i++) {
int sum = v1[i] + v2[i];
printf("sum - %d\n", sum);
}
return 0;
}
</code></pre>
<p>What would the logic look like to add the elements of two vectors of different sizes?</p>

74,439,569 | <p>I'm trying to build a quick and simple webpage to test an HTTP Requests service that I'm building, and Flask seems to be making it way harder than it should be. All I want is to display any incoming HTTP Requests on the page, and then return the received payload to the service that called the webpage.</p>
<p>Copying the Flask tutorial (plus the code for collecting HTTP requests) left me with this <code>app.py</code> file:</p>
<pre class="lang-py prettyprint-override"><code>from flask import Flask, request, abort, jsonify, render_template, Response, stream_with_context, url_for, redirect
app = Flask(__name__, template_folder = '')
responses = []
@app.route('/')
def index():
return render_template('index.html', resps = responses)
@app.route('/request', methods = ['GET', 'POST'])
def add_message():
print("Request dictionary: {}".format(request.json))
responses.append(request.json)
return redirect('')
app.run(host = '0.0.0.0', port = 81, debug = True)
</code></pre>
<p>I understand that <code>request.json</code> does not actually display all of the incoming data, but that is <a href="https://stackoverflow.com/questions/10434599/get-the-data-received-in-a-flask-request">easily solvable</a> assuming that the dynamic display of requests is at all possible.</p>
<p>And here's my <code>index.html</code>:</p>
<pre class="lang-html prettyprint-override"><code><!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Flask Response Test Page</title>
</head>
<body>
Web App with Python Flask!<br><br>
<label id="value_lable">
{% for resp in resps %}
{{ resp }}<br>
{% endfor %}
</label>
</body>
</html>
</code></pre>
<p>My service that sends Python requests is really simple and works great. Basically, users type in the endpoint, payload, and output variable, and my service will send the request to <code>endpoint</code> and store the response in <code>variable</code>. I know it works because I can reload my Flask test page and it will show the list of received requests, and my service is printing out the input JSON as the request response. This code runs inside a Docker container so I am using <code>http://host.docker.internal:81/request</code> as my endpoint for the purposes of this test as per <a href="https://stackoverflow.com/a/72188215/8705841">this answer</a>.</p>
<pre class="lang-py prettyprint-override"><code>import requests
class JSONGETRequest():
def on_start(self, executive):
# dict.get() returns None if the dict doesn't have the requested key
endpoint = self.node.data.get("url")
payload = self.node.data.get("payload")
variable = self.node.data.get("variable")
out = requests.get(endpoint, json = payload, headers = {"User-Agent": ""}).json()
executive.set_context(variable, out)
executive.next(self.node, "output_1")
</code></pre>
<h1>TL;DR:</h1>
<p>I've tried a <em>bunch</em> of different answers posted on StackOverflow that are related to this question and none of them worked. Everything after this is the various things I tried already.</p>
<hr />
<p>I attempted to use this page (<a href="https://stackoverflow.com/questions/40963401/flask-dynamic-data-update-without-reload-page">Flask Dynamic data update without reload page</a>) but that uses a button to force the page to reload, and I cannot find anything that indicates AJAX can activate/run a function whenever the page receives a Request. The vast majority of questions I've found relating to "flask update page data without refresh" all use a button but I really just want a streamed output of the requests as they come in.</p>
<p>Edit: Based on NoCommandLine's comment I was able to fix my implementation of this answer, but it still fails to update the page in real-time, and requires a page reload in order to update the displayed data.
I tried to use <a href="https://stackoverflow.com/a/64974111/8705841">this answer</a> ~~but got the error <code>werkzeug.routing.exceptions.BuildError: Could not build url for endpoint 'request'. Did you mean 'static' instead?</code> when using~~ with the following code:</p>
<pre class="lang-py prettyprint-override"><code>@app.route('/requests', methods = ['GET', 'POST'])
def add_message():
print("Request dictionary: {}".format(request.json))
responses.append(request.json)
def inner():
# simulate a long process to watch
for i in responses:
# this value should be inserted into an HTML template
yield i + '<br/>\n'
return Response(inner(), mimetype = 'text/html')
</code></pre>
<pre class="lang-html prettyprint-override"><code><!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Flask Response Test Page</title>
</head>
<body>
Web App with Python Flask!<br><br>
<div>
<!-- url_for() is based off of the target method name, not the page name-->
<iframe frameborder="0"
onresize="noresize"
src="{{ url_for('add_message')}}"
style='background: transparent; width: 100%; height:100%;'>
</iframe>
</div>
</body>
</html>
</code></pre>
<p>~~Which honestly makes no sense since the <code>request</code> page <em>should</em> exist since I created the <code>@app.route('/request')</code>- it fails with both <code>url_for('request')</code> and <code>url_for('/request')</code>.~~</p>
<hr />
<p>Supposedly there is "quite a few tutorials" on how to use AJAX but not a single on that I've found that even <em>MENTIONS</em> HTTP requests.</p>
<p>How is there not a website or service that already does this? Just take in any incoming requests and print them out. There's no reason this should be this hard.</p>
<hr />
<p>I tried using <code>@app.after_request</code> but it seems to be useless. And for some reason <code>render_template</code> is just a completely useless function that does absolutely nothing helpful:</p>
<pre class="lang-py prettyprint-override"><code>@app.route('/request', methods = ['GET', 'POST'])
def add_message():
print("Request dictionary: {}".format(request.json))
responses.append(request.json)
return request.json
@app.after_request
def update(response):
render_template('index.html', resps = responses)
return response
</code></pre>
<p><a href="https://stackoverflow.com/questions/55763277/flask-how-to-automatically-render-template-when-receiving-post-request">This question</a> is basically a duplicate but has no (useful) answers.</p>
