I want to get a script to: a) check if a number within the user defined range is prime or not b) print the result of a check c) print amount of numbers checked and how many of these numbers were primes d) print the last prime number

Here is what I have so far:

I'm trying to automate network diagrams and I'm having trouble getting rid of the label of the cloud shape. When I try to get rid of the -Label parameter, the cloud will not be drawn. I know that I can manually delete the label but is there a way to draw the cloud without using the -Label parameter? I've provided my code down below:

I have this Problem where Xcode can not Preview my Kotlin KMM App.

I created the App in Android Studio according to Kotlin. The Android App works and the iOS App aswell.

But the problem is im new to iOS development and Xcode. As far as I know I need Xcode to work on my iOS UI.

But as soon as I open the iOS App in Xcode, it says that the Scheme can not Build the Preview.

Here you can see the Error-Details

I already googled but couldn't find a proper solution.

The only thing I found out is that this often happens when the Project is not built correct.

Here's a Picture of my Structure: Xcode Project Structure

I hope for a quick solution because this kills the fun for me atm.

Working on a tutorial atm that involves react material-ui tables that also has a search input textfield. What I am trying to add to it, is a button that will reset the table report but also clear the search input textfield.

It is the clearing of the search textfield that I am having trouble with.

They are using this code as a separate component library called Controls.input:

import React from 'react' import { TextField } from '@material-ui/core';

Hello great people of SO!

I hope you all have a good day and have a good health

Note: I'm not good at SQL

Sorry for bad english, but I will try my best to explain my issue

I'm using Laravel v8.x for my app, and after setting up model relationships, events, queues, etc, now I'm working for SQL

ATM, I have 2 Models,

• User
• Post

Relationships:

• User hasMany Post
• User belongsToMany User (Block)
• User belongsToMany User (Follow)
• Post belongsTo User

Database: 5 record for User 2 record for Block 3 records for Post

Table: (Using faker)

users

I have a text file that I am trying to extract data from using regular expressions, here is a sample of the text file :

I have a relatively simple case where:

1. My program will be receiving updates via Websockets, and will be using these updates to update it's local state. These updates will be very small (usually < 1-1000 bytes JSON so < 1ms to de-serialize) but will be very frequent (up to ~1000/s).
2. At the same time, the program will be reading/evaluating from this local state and outputs its results.
3. Both of these tasks should run in parallel and will run for the duration for the program, i.e. never stop.
4. Local state size is relatively small, so memory usage isn't a big concern.

The tricky part is that updates need to happen "atomically", so that it does not read from a local state that has for example, written only half of an update. The state is not constrained to using primitives and could contain arbitrary classes AFAICT atm, so I cannot solve it by something simple like using Interlocked atomic operations. I plan on running each task on its own thread, so a total of two threads in this case.

To achieve this goal I thought to use a double buffer technique, where:

1. It keeps two copies of the state so one can be read from while the other is being written to.
2. The threads could communicate which copy they are using by using a lock. i.e. Writer thread locks copy when writing to it; reader thread requests access to lock after it's done with current copy; writer thread sees that reader thread is using it so it switches to other copy.
3. Writing thread keeps track of state updates it's done on the current copy so when it switches to the other copy it can "catch up".

That's the general gist of the idea, but the actual implementation will be a bit different of course.

I've tried to lookup whether this is a common solution but couldn't really find much info, so it's got me wondering things like:

1. Is it viable, or am I missing something?
2. Is there a better approach?
3. Is it a common solution? If so what's it commonly referred to as?
4. (bonus) Is there a good resource I could read up on for topics related to this?

Pretty much I feel I've run into a dead-end where I cannot find (because I don't know what to search for) much more resources and info to see if this approach is "good". I plan on writing this in .NET C#, but I assume the techniques and solutions could translate to any language. All insights appreciated.

I am new to JavaScript and D3.js and atm trying to create an Angular App with a stacked bar chart visualisation of the number of different test results 'OK', 'NOK' and 'Aborted' of each day as a stacked bar in the y-axis and the dates as the x-axis.

My data.csv looks like this:
