Concurrent Collections in C#
Tags: csharp
Published: 2024-01-12 14:24:26

C# Concurrent Collections in C# provide a powerful and efficient way to manage concurrent access to data structures in a multi-threaded environment. These collections are specifically designed to handle scenarios where multiple threads access and modify the same collection simultaneously.

One of the most commonly used concurrent collections is the ConcurrentDictionary. It allows multiple threads to add, remove, and update key-value pairs without the need for manual locking or synchronization mechanisms. This greatly simplifies the development process, as developers don't have to worry about race conditions or deadlocks.

Another useful concurrent collection is the ConcurrentBag. This collection is ideal for scenarios where you need to store a dynamically-sized collection of items that can be accessed by multiple threads simultaneously. The ConcurrentBag allows for efficient thread-safe addition and removal of items, making it perfect for tasks such as producer-consumer scenarios or parallel processing.

C# Concurrent Collections achieve their thread-safety by utilizing fine-grained locks and algorithms optimized for concurrent access. Under the hood, these collections use advanced techniques like lock-free programming and atomic operations to ensure that multiple threads can safely access and modify the collection without causing data corruption or inconsistency.

In addition to ConcurrentDictionary and ConcurrentBag, there are several other concurrent collections available in C# such as ConcurrentQueue and ConcurrentStack, each designed to address specific concurrency scenarios.

Overall, C# Concurrent Collections provide a reliable and efficient solution for managing concurrent access to data structures. They offer great performance and scalability, making them essential tools for developing multi-threaded applications in C#. Whether you're building a highly parallel application or simply need to handle multiple threads accessing the same data, these collections will simplify your code and ensure data integrity and consistency.

EXCEL - 8


LOOKUP AND REFERENCE FUNCTIONS. :- 

Function :- 

Row  -  It will return the row index as per the cell reference.
Rows - It returns the no.of rows in a ( range ).
Column - It returns the column index of the reference column.
Columns :- it will count and return the column number.

QUICK RECAP :- 

Filter - It takes input as a range and a multiple condition and gives output as a table.
 Important :- It doesn't take wildcards.

=FILTER(range, include, [if_empty])

It takes input as range and condition → condition should return boolean output so that it can give output a result.


Isnumber :- It will find out that anything in a number is numeric or not.

=ISBLANK(cell)



Filter function
Takes different arguments in Google sheets and Excel.

Multiple condition :- 

=filter(B2:B16,(B2:B16=B2)+(C2:C16=C3))
(*)  AND function 
(+)   OR   function 




Sort :- 

It gives output in a dynamic format. It sorts the data in ascending and descending order.
Sortby :- It sorts it but takes different parameters.
=SORT(range, [sort_index], [sort_order], [by_col])




Unique :- Give us unique values within a column.


LOOKUP FORMULA

HLOOKUP :- Help us to find in a horizontal format.
=HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])



Match :- it helps us to get the exact position of the cell.
=MATCH(lookup_value, lookup_array, [match_type])



Xmatch :- It is more flexible than the match function.
=XMATCH(lookup_value, lookup_array, [if_not_found], [match_mode], [search_mode])



Index :- It helps us to get the value at a particular position.
=INDEX(range, row_num, col_num)


VLOOKUP :- Helps us to get them in a vertical format. Right to left look up.
=VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])


XLOOKUP :- Both horizontal & vertical 
=XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found], [match_mode], [search_mode])




Index-match ( formula mix up is better than lookup)
=INDEX(return_range, MATCH(lookup_value, lookup_range1, 0), MATCH(lookup_value2, lookup_range2, 0))



Wild card is necessary to try to learn and use it. = ‘ * ’

How do you use your VSCode profile?
Tags: vscode, microsoft, ide, editor
Published: 2024-01-12 14:03:32

I've been using [VScode profiles](https://code.visualstudio.com/docs/editor/profiles) for a while, but I fee like my profiles are turnung into a mess. 

I started by just making a python profile. Then I made a profile from that one named data science. Then I made one with markdown tools and cspell for writing blog posts and note taking. Then I made one for rust. And one for writing django projects. Plus theres the built in default one.

The problems I'm now getting are that I wonder why my editor in data science view isn't type checking the way I expected it to, and it's because I tweaked those settings in Python, not Data Science. and I've found a great tool that I've added to my Django profile that helps with lots of python things, but I can only add it upwards to my default profile, not my python profile or the data science one, without having to switch it in, refind and install it, then switch back to what I was doing.

So the question is: Have you found a way to manage your profiles that you are happy with? 

I feel the problem is that the profile is a 'leaky abstraction'. It allows a lot of customisability to do what I've done, but that ends up with a muddle of profiles split by language OR task. 

I feel like a neat solution is to adopt profiles of

- default
- python
- rust
- R

OR 

- web development
- data science
- writing

CodeScene’s [latest whitepaper, Refactoring vs Refuctoring](https://codescene.com/hubfs/whitepapers/Refactoring-vs-Refuctoring-Advancing-the-state-of-AI-automated-code-improvements.pdf), has some interesting findings, quotes, and improvements for AI / LLM assisted coding.

Findings:
---------

1. LLM’s refactorings only correct 37% of the time
2. Using their fact checking, it can be increased to 98%

I’ve seen the tech press focus either #1 only to imply “see, told you LLM’s are harmful” or #2 only to imply “see, LMM’s are the best, you’re missing out”.

However, I’m intrigued by finding #3 which is hinted it a few times, but not explicitly called out:

3\. LLM’s are good for writing new code and helping you with idea’s.

When writing documentation, or a new test/new code, I specifically would turn Copilot off in VSCode because it was either way off base, or wrote documentation in some strange style; both were annoying. I gave up asking ChatGPT for help after 3 tries, even after learning a few prompt variations; the code was so bad and didn’t work, or just way off base. I’m unclear what new code they, the researchers, think these LMM’s are good at.

Quotes:
-------

- GPT 4 did give better results, but was slower and more expensive, negating the benefits
- regarding Copilot and CodeWhisperer “It’s safe to assume that a human developer shipping code which breaks 60-80% of the time would be asked to look for new challenges. Promptly.”
- “AI-assistant like Copilot or CodeWhisperer can be useful as the starting point for new code, serving as an inspiration and a coach” <– I have had the opposite reaction.
- “CodeScene’s fact-checking model is able to validate the proposed code changes, and reject 98% of the incorrect refactorings.” <– pretty amazing
- Their summary is compelling, mainly that aiming this at fighting technical debt has pays large dividends, not just in money but everyone happiness, so automating this is pretty compelling.

Your Good Code vs My Good Code
------------------------------

Their secret sauce has a few positive caveats to ’em. Their CodeScene tool which defines “good code” immediately sounds like ESLint. The problem with ESLint is that the “rules” are “a particular developer’s preference”. And this is why code is Art, not Engineering; we all have our own preferences and interpretations.

However, teams *\_do\_* end up convening on a common set of rules. That means the LLM could be coerced, configured, or even trained on “our version of good code” so uniquely useful to the team.
DOM is easy: Just make it work like an Array 👍

Modifying DOM elements without a framework can be tedious. The method names are long, and simple common tasks are split into tiny steps.

Wouldn't it be nice if the DOM was a bit more like an Array? Just push a new element, call `sort` or even `reduce` all the values into one.

-----

As part of a larger project, which I'm writing a longer post about at the moment, I built this convenient little helper that works well enough on its own that I want to write a separate little post about it.

[`domLense`](https://github.com/DarkWiiPlayer/skooma-js/blob/main/domLense.js?ts=3) is a module of less than 100 lines that lets you pretend a DOM element is actually an array. You can index it, `push` and `pop` values, loop it with `forEach` and even `map`, `reduce`, etc. it to get new values.

The way it works is simple: You tell the module how to get the interesting data from an element, and how to deposit different data back to it. Optionally, you define how new elements should be created.

```js
const transforms = {
   get(li) { return li.innerText },
   set(li, text) { li.innerText = text },
   new() { return document.createElement("li") }
}
```

In this case, our "interesting data" is just the text content of a bunch of `<li>` elements.

All that's left now is to call `domLense` on an unsuspecting list element, and we'll be able to treat it just like an array:

```js
const listElement = document.createElement("ol")
const list = domLense(listElement, transforms)

list.push("First item on the list")
list.push("Another item on the list")
list.reverse()
console.log(list.map(text => `* ${text}`).join("\n"))
```

I've prepared a small [codepen demo](https://codepen.io/darkwiiplayer/pen/MWxbKGv) to play around with this.

{% codepen https://codepen.io/darkwiiplayer/pen/MWxbKGv %}

The way this works isn't really that complicated. The helper simply creates a proxy that redirects integer indices to the element's child list applying the provided transformations. For any other keys, it tries looking them up in `Array.prototype`.
Guia de Instalação do Apache Maven
Tags: braziliandevs, java, maven
Published: 2024-01-12 13:41:03

## Introdução:

O Apache Maven é uma ferramenta de gerenciamento e entendimento de projetos de software. Ele centraliza e padroniza a construção do código e a gestão de dependências, facilitando a vida dos desenvolvedores. Este artigo visa fornecer um guia passo a passo para instalar o Apache Maven em seu sistema.

## Pré-Requisitos:

**Java Development Kit (JDK):** O Maven requer que o JDK esteja instalado no sistema. Verifique se você tem o JDK instalado e atualizado.

**Passo 1: Download do Apache Maven**

1. Acesse o site oficial do Maven: [Apache Maven](https://maven.apache.org/archetype/download.cgi).
2. Baixe a versão mais recente do Maven. Você encontrará opções para diferentes sistemas operacionais. Escolha a que corresponde ao seu sistema.

**Passo 2: Instalação**

## Para Usuários de Windows:

1. Extraia o arquivo baixado em um diretório de sua escolha (por exemplo, `C:\apache-maven`).
2. Adicione o caminho do diretório bin (ex: `C:\apache-maven\bin`) ao `PATH`do sistema. Isso permite que você execute o Maven de qualquer local no prompt de comando.
3. Verifique a instalação abrindo o prompt de comando e digitando `mvn -v`. Isso deve mostrar a versão do Maven e do Java.

## Para Usuários de Linux/Mac:

1. Extraia o arquivo baixado em um diretório, como `/usr/local/apache-maven`.
2. Adicione o diretório bin do Maven ao PATH. Você pode fazer isso adicionando uma linha ao seu arquivo `.bashrc` ou .`bash_profile`: `export PATH=/usr/local/apache-maven/bin:$PATH`.
3. Para verificar a instalação, abra o terminal e digite ` mvn -v `.

## Passo 3: Configuração (Opcional)

Você pode configurar o Maven de acordo com suas necessidades editando o arquivo `settings.xml`, localizado em `apache-maven/conf`.
Este arquivo permite definir configurações de proxy, servidores e outras preferências de compilação.

## Conclusão:

Com o Maven instalado, você está pronto para iniciar ou continuar seus projetos de software com uma ferramenta poderosa e eficiente de automação de build. Lembre-se de sempre verificar a documentação oficial para obter informações mais detalhadas e atualizadas.

What Makes Users Click? - KAWWARD
Tags: design, ux, ui
Published: 2024-01-12 13:33:44

Ever wondered why some websites make you click every button while others leave you bored and hitting the backspace? It's all about web design magic, where designers use sneaky tricks to guide you around and make you take action. Let's lift the curtain and see what makes the click-o-meter tick!

## 1. Color Power!

Colors are like superhero costumes for websites. Red is like a bold captain, urging you to click the "Buy Now" button. Blue is a calm teacher, guiding you through long articles. Designers use color palettes to create moods and lead you where they want.

## 2. Eye-Catching Hierarchy

Imagine a website like a crowded playground. Your eyes are drawn to the biggest kid (the headline) and the ones with the coolest toys (the bright buttons). Designers use size, contrast, and white space to make important things stand out, like a map leading you to the treasure (the call to action).

## 3. Tiny Twinkle, Big Fun!

Ever noticed how buttons wiggle when you hover over them? Those are microinteractions, like little winks from the website. They make things feel alive and fun, encouraging you to explore and click around. It's like the website is saying, "Hey, touch me, I'm not boring!"

## 4. Story Time!

People love stories, and websites can tell them too! With pictures, words, and even videos, designers weave narratives that make you care about the website's message. When you connect with the story, you're more likely to click, swipe, or buy something. It's like being invited on an adventure!

## 5. Forms? No Drama!

Filling out forms can be a nightmare, but designers can make it painless. Short forms, clear labels, and helpful error messages make things smooth and easy. The faster you zip through the form, the quicker you get to the good stuff, like that free ebook download!

## Bonus Tip: Button Buzzwords!

Words like "**free**," "**exclusive**," and "**limited time**" are like tiny magnets for your mouse. Designers use them on buttons to create a sense of urgency and make you click before it's too late. It's like the website whispering, "Don't miss out!"

Remember, web design is like a friendly conversation. By understanding these tricks, you can create websites that are both beautiful and persuasive. So next time you visit a click-magnet website, take a moment to appreciate the invisible magic at work!

What is hoisting in javaScript?
Tags: hoisting, javascript, frontend, webdev
Published: 2024-01-12 13:24:04

Hoisting Basically when we run JavaScript code than it's do every global variable and function go in the top. its called hoisting.
**Variable hoisting: **

console.log(x); // undefined
var x = 5;
console.log(x); // 5

**Functional Hoisting: **
sayHello();

function sayHello() {
  console.log("Hello, World!");
}
**Note:** 
var and let/const declarations. let and const are block-scoped and are hoisted but not initialized until their actual declaration in the code, resulting in a "temporal dead zone" if you try to access them before the declaration.

Like
console.log(a); 
let a = 10;

Show This error: VM156:1 Uncaught ReferenceError: a is not defined at <anonymous>:1:13
