Java Thread: Real world Application Example

I was asked a question in an interview, where i have list available in the main method and and i was told there is some operation to be performed on each item in the list, how would i achieve this using threads concept.
Consider the following scenario:
I have a list of integers. I need to print all the values from the list. Can it be done using threads concept where i have multiple threads running on each item in the list and where each thread is used to print out a value rather than one thread printing all the values? I am not trying to modify any value in the list.

Pyomo error: No value for uninitialized NumericValue object

I'm a very new Pyomo user. I have been trying to find examples similar to my problem but I couldn't find any that were neither too easy or too difficult. It appears I have a problem initializing a variable but I can't figure out how to fix it. Here's my code:
`# Import of the pyomo module

Transform a blurhash to grayscale

Does anyone have an idea of how we can implement an efficient algorithm (js/ts) that given a blurhash string returns the equivalent (even of reduced quality) but in grayscale?


I need it because I use blurhashes as image holders, but in a part of my application I need to display images in black and white. Thanks in advance

---



EDIT


I managed to arrive at a code like this. the problem is that the blurhashes seem stretched and deformed compared to the originals
const WIDTH = 30;
const ASPECT_RATIO = validationConfig.media.profilePicture.aspectRatio;
const HEIGHT = Math.floor(WIDTH / ASPECT_RATIO);

export function convertBlurhashToGreyscale(blurhash: string) {

const pixels = decode(blurhash, WIDTH, HEIGHT);

for (let i = 0; i < pixels.length; i += 4) {
const grayValue = Math.round(
(pixels[i] + pixels[i + 1] + pixels[i + 2]) / 3
);

pixels[i] = grayValue;
pixels[i + 1] = grayValue;
pixels[i + 2] = grayValue;
pixels[i + 3] = 255; // Imposta l'opacità a 255
}

const newHeight = Math.floor(WIDTH / ASPECT_RATIO);
return encode(pixels, WIDTH, newHeight, 4, 3);

Laravel Breeze with PrimeVue

I just finished creating a Laravel Breeze equivalent starter kit using PrimeVue and PrimeFlex, the inspiration was to have a starter kit that would provide a larger selection of Vue components out of the box. Feedback is welcomed and appreciated!

I'm considering abstracting this into a composer package, but decided to see if there was any interest in the idea first. Perhaps a PrimeReact version as well?

add values to the array object key by clicking the button with this value react

I have three buttons that when clicked I want to add a value to a selected field that is added dynamically:
const [Fields, setFields] = useState([
{ value: null, current: true },
{ value: null, current: false }
]);



value - is the key I want to add values to when the button is clicked


current - these keys store the state of the selected field when the field is clicked on
const [Fields, setFields] = useState([
{ value: null, current: true },
{ value: null, current: false }
]);

const GetSymbol = (event) => {
const symbol = event.currentTarget.dataset.value;
return symbol;
}
const InsertSymbol = (curField) => {
curField = GetSymbol;
return curField;
}

GetSymbol(event)} data-value="A">A
GetSymbol(event)} data-value="B">B
GetSymbol(event)} data-value="C">C

{Fields.map((field, i) => {
return (

{
setFields((oldArr) => {
let newArr = oldArr.map((item, index) => {
return {
...item,
current: index === i ? true : false,
};
});
return newArr;
});
}}
>
InsertSymbol(field.value)


);
})}



if the key current is true in the current field, then you must populate the values in field.value for that field.


I.e. If you click on A and B buttons, the value of field.value will be AB.
In my code, the functions GetSymbol and InsertSymbol are incorrect.


Please help me with this!

What's a better solution to tackle this problem - export / clone and restore for complex nested relations

You'll have to excuse the confusing title, I was trying to come up with a way to describe the many components to this challenge I'm trying to iterate on and come up with a better solution then the existing one.

Allow me to summarize. Our company provides an architecture design tool that, to simplify, allows customers to create projects, which contain architectures, which contain elements, interfaces, which contain requirements, tests, which contain.. etc etc. Lots and lots of nested relations. A project, after a few months usage, can easily contain thousands of records spanning two dozen tables, representing one-to-one, one-to-many and many-to-many relationships.

Currently all tables use an auto-increment numerical ids.. your standard stuff. Most tables also contain a project_id table which itself is just an integer.

Enter feature #1. The ability to export your project with all of its nested relations. This was simply enough.. we just load our project and recursively load all of its relationships, and then we just dump that whole thing as an array to a json file. This saves a full copy of the project with all of its relations represented by the values of thousands of primary keys at the time of export. Easy.

Enter feature #2. The ability to clone the above extremely complex project. Currently, we export the above, and then we have this complex script that iterates over every level of relation from the json dump and creates a new copy of everything. As it's doing this, it's storing all the reference primary ids from the json dump, and creating a relation map of sorts that it then uses to re-attach all the relations but using the new ids that are being created thanks to the auto-increment ids of the new copies.

Read that again if you must.. this one is a bit of a nightmare, this is not a piece of code I am happy with right now and is the constant source of issues. Before I describe what I think is a better way.. let's talk about the last feature.

Enter feature #3, the ability to restore a previous import (you can also think of these imports as a versioning system but not just for a single model but for a huge project). When you restore a project, you're overwriting the existing project and you must end up with the full working project with its thousand nested relations.

In a way, both cloning and restoring results in the same project state, but in the former case you end up with two projects where the cloned project will of likely diverge from the original, and in the case of restoring you still only have just the one project. I haven't done the restore feature yet.

Keeping in mind that the same database houses hundreds of these complex projects.. and each table having tens of thousands of records with different numerical ids that belong to different projects.

So restoring a project with the current system.. for example taking a project which at the time of export had 1000 nested records and now the current project has 3000, but after restoring we need to be back to 1000 (as an example).. this operation is quite a tricky one when using auto incrementing ids.

So voila.. this is the problem I'm currently facing. And I was just thinking aloud tonight of how to do this in a much better way.. and I'd love to hear all your thoughts about it before I talk about my new idea.

Really appreciate your thoughts actually : ) I don't come to Reddit often for coding problems but this one is a bigger task that's been on my mind a lot.

Oh and btw of course I'm using Laravel 10 here.

The first thought I had is that this could be dealt with with a NoSQL approach. But I kind of dread NoSQL and no way do i want to suggest that we move away from MySQL to something like Mongo at this time so we must stick to using a relational DB. I also don't want to use a different DB for each project. I am already dealing with 40+tables and having hundreds of dbs to manage would be a big nope.

The second thought I had is: use composite primary keys everywhere. Each project has a unique hash for a primary key and then everything else that is attached to it has a primary key that makes use of the project's unique key. Ignoring the pains and caveats that come with using composite primary keys.. this appears to make everything waaaaay easier. The export feature is the same as before. Cloning just involves creating a new project hash and then replacing it everywhere before inserting every records as is.. no need to relink things it just works and we just need to change one key.

And same for restoring.. we just wipe absolutely every record that contains the project key that's being restored and then we just restore the dump as-is.

Am I missing something or is this a waaay better solution?

The caveats with composite keys is that it can be less performant when making queries and it requires a lot of refactoring. Sometimes dependencies don't play well with composite keys.

I can't really think of another approach at the moment. What do you think about the composite key approach?

if you read this far.. I hope you're finding this mildly interesting! Thank you for making it this far and thanks a lot should you decide to share your wisdom developer to developer ;-)

Kind regards! submitted by /u/spar_x

Question regarding arrays and sequences in Java

I'm not sure on how to write this out in java code: "If the function is not null and the current index is less than the size, then the function array must agree with the field at the current index." It's listed as number six under wellFormed(). I just don't understand on how to check that the function array doesn't agree with the field at the current index, so i can throw a report. Thank you for the help !


This is the code that's relevant:




*
import java.util.function.Consumer;

/**

A Robot implemented with a dynamic array data structure

and providing "Sequence" capabilities. This is a homework assignment

inspired by Main: "Data Structures and Other Objects in Java" Chapter 3

(Sequence ADT). */



*
public class DynamicArrayPartSeq implements Robot, Cloneable { private static final int INITIAL_CAPACITY = 1;

// Data structure: Do not add or subtract from this: private String[] functions; private Part[] parts; private int size; private String function; private int currentIndex;

private static Consumer reporter = (s) -> System.out.println ("Invariant error: "+ s);

private boolean report(String error) { reporter.accept(error); return false; }

private boolean wellFormed() { // XXX: The invariant should be adjusted: no holes allowed // and it needs to check currentIndex and function

// 1. The "functions" and "parts" arrays must not be null.
// TODO
if (functions == null) {
return report("functions cant be null");
}
if (parts == null) {
return report("parts cant be null");
}

// 2. The "functions" and "parts" arrays are always the same length.
// TODO
if (functions.length != parts.length) {
return report ("functions and parts arrays should always bt the same length");
}

// 3. The size cannot be negative or greater than the length of the arrays.
// TODO
if (size < 0) {
return report ("size cant be negative");
}
if (size > functions.length) {
return report ("size can't be greater than functions length");
}
if (size > parts.length) {
return report ("size can't be greater than parts length");
}

// 4. None of the first “size” elements of either array can be null. (ie. no holes)
// TODO
if (size == 0) {
return report("first 'size' elements of either array cant be null");
}

// 5. The current index cannot be negative or greater than the size.
// TODO
if (currentIndex < 0) {
return report ("index cant be negative");
}
if (currentIndex > size) {
return report ("index cant be greater than the size");
}

// 6. If the function is not null and the current index is less than the size, then the
// function array must agree with the field at the current index.
// TODO
if (function != null && currentIndex < size) {

}

// If no problems discovered, return true
return true; }







I wrote out the first if regarding to check that the function isn't null and the current index is less than size. The second comment "function array must agree with the field at the current index" is throwing me off. I tried writing it as a second if statement inside the first, but I'm unsure on what to insert as the conditions.

A simple statistic tool for Laravel apps

Hi folks,

a problem that I often face, when using analytic tools like Google Analytics oder Fathom Analytics is that they mostly show you data like visits, views, and page impressions. Everything beyond that, you need to integrate manually. That's why I started working on SimpleStats; it gives you KPIs like Reg, DAU, ARPU, ROI and much more out of the box, with a very simple installation!

The tool is not yet ready to launch and I don't know if anybody is interested in such a thing, but all tools I found out there, seem far to complicated to setup for me.

🚀 All you will need to do to get SimpleStats up and running is: Install a composer package, adjust the config to your needs, create an account, and add the token to your env file. Congrats, you're ready to analyze your campaigns and users!

📈 Here are a few of the KPIs that the tool provides: Registrations, Daily Active Users, New Active Paying Users, Average Revenue per User, Paying User, Revenue and much more. Everything filterable by date and UTMs!

🌟 Since the statistics tool and the composer client package are tailored precisely to Laravel, they can collect very interesting and important data without any additional complexity for you as the integrator of the package.

💻 Even though the composer client package is dedicated to Laravel, the API basically works with every client! So if you'd like to use the tool, even if you're not using Laravel, just trigger the API requests manually.

📍 Since the tool by default collects UTMs and Referrers for you and connects it with your users and their payments, it's super easy to see which of your marketing activities leads to revenue. You can simply analyze the ROI of your campaigns from the dashboard!

🛡️ We are fully committed to privacy compliance! No cookies are required or stored, ensuring your data remains confidential. You can rely on SimpleStats to respect your privacy and guarantee that your data will never be shared.

🏢 Collaborate by creating a team, inviting your co-workers to your projects, and assigning permissions to them. Each team is separated by tenancy, ensuring highly secure and robust data integration!

🎁 There will always be a free plan! If your business grows, you can support us with by subscribing. We would love to help you analyzing your campaigns. No need to enter credit card information at the registration.

Function is not running as expected [duplicate]

Why insertMany does not create ObjectIds in mongoose?

Currently I'm developing an APP using Node.JS and MongoDB. I'm trying to insert multiple documents with predefined _id s and some ObjectId arrays.
When I use insertMany all documents _id fields are strings instead of ObjectId. However when I use create and pass an array it works fine but instead of one query it performs separate query for each item of the array.


As it is obvious as the array grows it would be critical problem.


How can I use insertMany with the fields of type ObjectId instead of string?

Numbers with either comma or dot as separator : handle in front or back ?

Hi

My app is used by users that are either using comma or dot as a decimal separator.

The laravel backend is expecting a DOT as a number separator, because of "number" rule in form requests, and because of mysql.

The frontend is a Vue SPA app.

I've tried to change the validator rule so numbers are both accepted as "dot" or "comma" serapated, but then the DB complains about comma numbers !

So, I was wondering what should be the best practice : should the frontend ensure that numbers containing comma are replaced with dots before sending the SAVE call, or should it be handled on backend ? submitted by /u/Napo7

Laravel Pulse monitor multiple domains

Hello all,

Is Laravel Pulse able to track multiple domains ? I am running Pulse on a Laravel application and this works nice. Seeing slow queries and exceptions (glad not to many :D ).

However I have multiple Laravel applications, can those application report to a single Pulse installation so that I can see all errors / slow queries etc in a single dashoard ? This gives me a single entry for overviewing issues. Or are there other tools that can archive this.

I know that Sentry etc excists, but as above projects are "hobby" projects, I prefer something free / selfhosted on the server. That's why I like Pulse :) submitted by /u/Noaber

Unrecognized options while configuring newlib

I'm trying to build newlib with the ARM option "mno-unaligned-access. I downloaded and built the GNU ARM toolchain from the gcc-arm-none-eabi-10.3-2021.10-src.tar.bz2 package on ARM's website. Then I navigated to the newlib directory and attempted to rebuild newlib with "mno-unaligned-access" but I'm getting an unrecognized error when configuring:

Is there anything I could do to rebuild newlib with the ARM option specified? Do I new to rebuild the GCC toolchain with "arm-none-eabi" specified as the target?

Is this proper semantic html?

I'm making a component for a website where I need to make a checklist with the different W3C guidelines. I currently use a form as a parent element with an article and different details/summary elements inside but I feel like this is not correct semantic HTML. Outside of the component I already use a and so I'm not worried about that. I just feel like I'm using the and elements wrong.

{#each principe.richtlijnen as richtlijn}


Richtlijn {richtlijn.index}


{richtlijn.titel}



{#each richtlijn.succescriteria as succescriterium}




Criteria {succescriterium.index} ({succescriterium.niveau})


{succescriterium.titel}



e.id === succescriterium.id)}
/>


{@html richtlijn.uitleg.html}

{/each}

{/each}




This is the current live link for the component:
https://dry-checklist-vervoerregio.vercel.app/ (It's the only component live because it's a school project).


Can anyone help me make my HTML more semantic?

Dive into the Streamlined Directory Structure in Laravel 11

---



We think you’ll love the fresh skeleton you start with in a Laravel 11 app that is coming out next week! Newcomers will appreciate the minimalism, and experienced developers upgrading will not experience breaking changes in how a typical Laravel application is structured.


If you want to follow along and experiment, you can create a Laravel 10 and Laravel 11 project side by side. We used the following commands to do so:
# Update the installer
composer global update laravel/installer -W

cd path/to/projects

# Create a Laravel 10 app
laravel new laravel-10-app -n --git --pest

# Crate a Laravel 11 app
laravel new laravel-11-app --dev -n --git --pest



On the surface, the project directory structure looks identical:





However, if you start diving into the subdirectories, the file count has dropped from a fresh Laravel 11 installation by ~ 69 files:
# Fresh Laravel v10 app
$ find . -type f -not -path "./vendor/*" | wc -l
=> 217

# Fresh Laravel v11 app (as of 01/29/2024)
$ find . -type f -not -path "./vendor/*" | wc -l
=> 148



Let's review the most significant updates and see how they compare to a Laravel 10 application so you can be ready for the changes coming to fresh Laravel 11 apps.


The app Directory




The app directory has been slimmed down tremendously, moving the nine middleware that ships with Laravel into the framework and out of the project. Typically, these middleware are not heavily customized, and Laravel 11 will provide other methods to customize built-in middleware and add your own middleware.



The app directory in a fresh Laravel 11 app


Middleware changes are done through the bootstrap/app.php file, which is, according to Taylor Otwell, a “lean routes-esque style file for configuring Laravel” that looks like the following:
return Application::configure(basePath: dirname(__DIR__))
->withProviders()
->withRouting(
web: __DIR__.'/../routes/web.php',
// api: __DIR__.'/../routes/api.php',
commands: __DIR__.'/../routes/console.php',
// channels: __DIR__.'/../routes/channels.php',
health: '/up',
)
->withMiddleware(function (Middleware $middleware) {
//
})
->withExceptions(function (Exceptions $exceptions) {
//
})->create();



You could add an application middleware by adding something like the following in the withMiddeware() closure:
$middleware->web(append: \App\Http\Middleware\ExampleMiddleware::class);



The Kernel.php files are no longer in the Laravel project, and these are handled through the framework bootstrap/app.php file.


You might have also noticed that the Controllers directory only includes one Controller class that doesn’t extend from anything. It’s up to you how you’d like to extend your controllers (or not), but it provides a default abstract Controller class.


The config Directory




The biggest shock for you might be the updated config directory, which has…nothing inside of it (other than the .gitkeep file). You will, however, notice that many more configuration options exist in the .env.example file.





If you want to publish any given configuration file from the framework to customize it, you can do so via the config:publish command:
# config/database.php
php artisan config:publish database

# config/logging.php
php artisan config:publish logging

# Or publish all of them
php artisan config:publish



You are free to only extend the configuration values you care about, and they will be merged with the framework’s defaults so you don’t have to keep all published configuration options in a given file.


Suppose you want to look up configuration values in the framework-shipped configuration. In that case, you can use the Artisan config:showcommand, publish the config, or look it up in the config/logging.php file within the Laravel vendor folder:
php artisan config:show logging

cat vendor/laravel/framework/config/logging.php



The database Directory




The database directory is roughly the same. However, you’ll notice that the migration filenames are prefixed in a way that does not represent a given date but keeps them in order as needed. The create_personal_access_tokens.php migration file is no longer in the project. Personal access tokens are only required if you build an API, which we will cover in the routes directory changes.



Also, the database.sqlite file will be installed by default unless you pick a different database option when creating a new Laravel project.


The routes Directory




The routes directory was also slimmed down only to include the web.php and the console.php routes files. If you want to create an API or use the broadcasting functionality, you can install them via artisan:
php artisan install:api
php artisan install:broadcasting



Those commands will bring in the required migrations, JavaScript, and configuration files. What’s nice about this is that applications that don’t need broadcasting or API routes don’t have to worry about these unnecessary files being in the project.



Laravel 11 routes directory


The test Directory




The test/ directory no longer includes the CreatesApplication trait in Laravel 11 projects. If you upgrade your Laravel 10 project, you can remove this trait, as it’s now provided as part of the base TestCase from the framework.





In a Laravel 10 project, the only thing included in the base TestCase class in Laravel 10 is the CreatesApplication trait, which bootstraps the application when creating a fresh application as part of the setup before each test. You can safely remove this trait (and its usage) once you upgrade existing apps to Laravel 11.

Linker Error: how to work with clang library?

I am currently working on a C++ project involving the Clang library for code tokenization. After installing the Clang library using apt-get install, I proceeded to set up my project's CMakeLists.txt for building.

Return cells that contain numbers with recurring digits

I have a large dump of data containing in which column A has TOTAL AMOUNTS. In column B, I'd like Excel to simply say "yes" or "no" if the cell contains a number that has any digit recurring 4 times or more consecutively.
For example: if a cell contains the number 38,353.03 this would bring "no"
For example: if a cell contains the number 3,404,444 this would bring "yes"


I tried a formula using LOOKUP(SUMPRODUCT(LARGE(FREQUENCY(--MID(
but that was a disaster


so I'm at a loss

Imcremental data import in Power BI Desktop table

In my Power BI desktop model, I have a fact table with 10 million rows.
Every day, I need to add (import) 600,000 new rows to this fact table inside Power BI desktop from SQL server data warehouse.
My concern is how can I incrementally import these new data and add it to the already existing one in my Power BI Desktop model.
Simply refresh data will read every day all the 10 million rows which will be time consuming.


I tried to modify the M code of the fact table to get new rows after a specific date but this solution completely erase the already 10 million rows of the fact table in Power BI Desktop.


Below my M code
let
Source = Sql.Database("10.Xx.Xx.Xx", "MY_DB"),
dbo_fact_table = Source{[Schema="dbo",Item="fact_table"]}[Data],
filteredRows = Table.SelectRows(dbo_fact_table, each [date] >= StartDate)

in
filteredRows
