Using Memory<T> and Unsafe Code for Memory Manipulation
Tags: csharp, programming
Published: 2023-09-23 03:31:53

C# provides the `Memory<T>` struct, representing a chunk of memory, allowing you to work efficiently with arrays and spans. Combining `Memory<T>` with unsafe code will enable you to perform low-level memory manipulation operations for performance-critical scenarios.

Below is an example that demonstrates copying data using `Memory<T>` and unsafe code. In this example, `Memory<T>` represents source and target arrays, and unsafe code is employed to perform a memory copy operation between the arrays. The fixed statement pins the arrays in memory to avoid them being moved by the garbage collector during unsafe operations.

While this technique can lead to performance improvements, it comes with risks and should be used cautiously. Unsafe code can introduce memory-related bugs and security vulnerabilities if not handled correctly. Understand the pitfalls thoroughly and consider using safer alternatives when possible.

```csharp
using System;

public class Program
{
    public static void Main()
    {
        int[] sourceArray = { 1, 2, 3, 4, 5 };
        int[] targetArray = new int[sourceArray.Length];

        var sourceMemory = new Memory<int>(sourceArray);
        var targetMemory = new Memory<int>(targetArray);

        CopyMemory(sourceMemory, targetMemory);

        Console.WriteLine(string.Join(", ", targetArray));
    }

    public static unsafe void CopyMemory(Memory<int> source, Memory<int> target)
    {
        fixed (int* srcPtr = source.Span)
        fixed (int* tgtPtr = target.Span)
        {
            int* src = srcPtr;
            int* tgt = tgtPtr;

            for (int i = 0; i < source.Length; i++)
            {
                *tgt++ = *src++;
            }
        }
    }
}
```
Using yield for Deferred Execution
Tags: csharp, programming
Published: 2023-09-23 03:29:15

C# provides the yield keyword, which can be used to create iterator methods. These methods produce a sequence of values lazily, allowing for deferred execution. This can be particularly useful when working with large data sets or when you want to avoid loading everything into memory at once.

In the below example, `GetNumbers()` is an iterator method that yields a sequence of squared numbers. The key here is that the values are generated one by one as you iterate through the sequence, and they're not all calculated and stored in memory at once.

The `yield` keyword allows you to maintain the state of the iterator between iterations and offers a clean way to implement custom iterators without explicitly managing state variables.

This approach is beneficial for scenarios where loading or calculating all the values at once is memory-intensive or time-consuming. It's a powerful technique to create more memory-efficient and responsive code.

Remember that while the yield keyword can be a great tool, it's important to understand how it works, as it can have implications on resource management and potential side effects when used in certain ways.

```csharp
using System;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        foreach (var number in GetNumbers())
        {
            Console.WriteLine(number);
        }
    }

    public static IEnumerable<int> GetNumbers()
    {
        for (int i = 0; i < 10; i++)
        {
            yield return i * i;
        }
    }
}
```
Enhancing the Til-Tool

Published: 2023-09-23 03:26:48

The Til-Tool, a command-line utility for converting .txt files to HTML, underwent significant improvements with the addition of Markdown support. This article delves into the enhancements made to the tool and highlights the challenges faced during the development process.

The primary goal was to enable the Til-Tool to process Markdown files, transforming them into HTML documents. This feature allows users to convert Markdown content effortlessly, widening the tool's scope and utility.

The journey was not without hurdles. Issues like handling Markdown-to-HTML conversion, supporting various file extensions, and managing user input posed challenges. Ensuring a seamless user experience while handling different scenarios was pivotal.

By implementing robust file parsing and conversion logic, refining user input handling, and enhancing overall usability, these obstacles were effectively tackled.

The Til-Tool's evolution through the incorporation of Markdown support demonstrates the commitment to enhancing user experiences and addressing real-world needs.
Getting Better At GitHub
Published: 2023-09-23 01:18:49

## Great opportunity to Work on a different project 
This week's task for my open source course was about working on a project other than mine, and the goal was to get better with some of GitHub features like: creating issues, forking, cloning and pull requests. So I asked one of my classmates who had written his text to html converter program in Python, if I could add markdown to html support to his [project](https://github.com/Namatuzio/tiller). After getting his approval, I forked his project and created an [issue](https://github.com/Namatuzio/tiller/issues/14) explaining what I was going to contribute.

## The process

1. I went over the code base to understand the overall structure of the program so that I could make my contribution by making the least amount of changes to the original logic.
2. After understanding the structure, I decided to add markdown support so that the program would accept .md files in addition to .txt files. After testing every scenario that I could think of I committed the changes to my branch.
3. I decided to add Heading1(\#) to \<h1\> feature for the markdown to HTML conversions. Again, after testing everything to make sure what I added  worked and didn't change the existing functionalities I committed my code.
4. I made changes to the documentation and sample examples to reflect the new feature added to the project and committed them.
5. Created a detailed [Pull Request](https://github.com/Namatuzio/tiller/pull/15) reflecting the changes that I had made.
6. Received feedback from the project owner and made some small modifications based on that.
7. The project owner accepted the updated Pull Request and merged it to his project.

## Learnings

- This was a great opportunity to get some practice using Python, which is something that I wanted to get my hands on.
- I didn't know that a Pull Request can be linked to an issue in a GitHub repo, so that was interesting!
- I learned that I am more focused and put more care into working on someone else's project.

## What I would do differently

One thing that I will do different in future when contributing to someone else's project is to go over the planning stages of my contribution with them, if that is a possibility.

## Problems

The only thing, which was not really a problem, was getting used to Python's syntax and learning about the tools that the language offers.

## Pull Requests to my project

I received [Pull Requests](https://github.com/Amir-Helali/Txt2StaticHtml/pull/4) to my own project. The process and the communication was very smooth and similar to what I did, because it was from the owner of the project that I contributed to. We went over the changes after the initial Pull Request and I requested some adjustments in my feedback, which were made in the updated PR.
Perl Weekly Challenge #235 - Splicing and Dicing
Tags: perl, perlweeklychallenge
Published: 2023-09-23 00:16:03

Hi everybody, we've got another two challenges this week, so let's dive into them!

#### Remove One

The goal is to see if there's any one number that can be removed to make the set sorted in increasing order. Here's the code:

    #!/usr/bin/perl
    use v5.36;

    my $success = 0;
    REMOVAL: for my $removal (0 .. $#ARGV) {
        my @modified = @ARGV;
        splice(@modified, $removal, 1);
        for my $scan (1 .. $#modified) {
            if($modified[$scan] <= $modified[$scan - 1]) {
                next REMOVAL;
            }
        }
        $success = 1;
        last;
    }

    say ($success ? 'true' : 'false');

We have a labelled outer loop for the numbers we choose to remove. $removal is set to the index of each number we attempt to remove, then we copy the array, remove that number, and scan the result to make sure they all are increasing. If they don't, we skip this number and move on.

If we succeed, we set our flag and exit the loops and print the result.

#### Duplicate Ones

The next one is an array shifting challenge. We want to insert a duplicate of each 0, shifting everything to the right, and popping off the list to keep the length the same.

Here's the code:

    #!/usr/bin/perl
    use v5.36;

    my @ints = @ARGV;
    for(my $i = 0; $i <= $#ints; $i++) {
        if($ints[$i] == 0) {
            splice(@ints, $i, 0, 0);
            pop(@ints);
            $i++;
        }
    }

    say('(', join(', ', @ints), ')');

This one's also really quite simple. We scan the array, use splice to insert a 0, pop the last number off the end of the array, and skip over the 0 we just inserted. It's that simple!

Both of this week's solutions make use of splice() to insert and remove array elements, something I haven't used a lot before.

Stay tuned for next week's challenge, which should come out Monday!
Singleton Connection with Transactions in MongoDB
Tags: javascript, tutorial, programming, node
Published: 2023-09-23 00:05:47

I was looking at some patterns on how to use MongoDB Transactions but I want it to be a common wrapper and should be simple enough for nodejs beginners (like me) to understand. I saw some functions accepting another, function with multiple parameters, as a parameter, but you need to take care of `overloading` cases.

Thinking of a simple solution, why not just wrap all arguments into a single variable like a `map`.  This may not work for others but certainly works on our case.

First, I need to make sure that I only have 1 DB Connection always. Hence I created a `Singleton` class.

```
const mongoose = require('mongoose');
...
...

// Define Singleton DB Connection Class
class Connection {
  constructor() {
    if (!Connection.instance) {
      mongoose.connect(config.mongoose.url, config.mongoose.options);
      this.conn = mongoose.connection;
      this.conn.on('error', () => logger.error.bind(console, 'connection error'));
      this.conn.on('open', () => logger.info(`Connected to MongoDB ${config.mongoose.url} for Transaction...`));
    }
  }
}

module.exports = new Connection();
```
I will use this class in every part of my systems and it will ensure that I won't be having multiple cases of DB connection.

Now to create a transaction wrapper, I do this. This is a self-managed transaction meaning I dont need to call commit and rollback. But if you want to manually handle each commit and rollback, you may do so here as well.

```
const db = require('./connection');

const withTransaction = async (fn) => async (map) => {
  const session = await db.conn.startSession();
  await session.withTransaction(fn(map), { session });
  session.endSession();
};

module.exports = withTransaction;
```

To call do something like this:
```
async function saveFunction(map) {
  //.. implementation
  const { var1, var2 } = map;
  // use the var1, var2 here ....
  // call mongodb CRUD here 
}

// service call
const save = async (map) => {
  withTransaction(saveFunction(map));
};
```

Hoping to get some comments so that I can improve this wrapper in the future.
I Built A SaaS Directory That Uses AI To Recommend Tools
Tags: watercooler, showdev, community
Published: 2023-09-22 23:25:21

So I've always wanted to randomly build a tool directory for some reason.

They're usually pretty light in terms of tech requirements, and it's something completely different compared to what I've done with past projects.

I was sick a few weeks ago and decided to use my downtime to work on one. 

There are a lot of these types of directories out there, so I wanted to try and figure out how to make mine stand out a little more.

**What better way to do it than with AI? LOL**

A problem I've heard and noticed when it comes to these directories is that there's simply too much to sift through. I've come across the same problem myself.

So I decided to sprinkle in a little AI. Basically, you describe a problem you're having and we'll recommend some tools that we think could help in some way or another.

![findcool.tools ToolFinder Ai](https://media.giphy.com/media/v1.Y2lkPTc5MGI3NjExbGp5cHZrbHdkcGc5OW1za3pkMDh4c2JnN3lpZDJjbm9lMG12bHR6aSZlcD12MV9pbnRlcm5hbF9naWZfYnlfaWQmY3Q9Zw/aJZiluAHlVmz6hvZhQ/giphy.gif)

The majority of tools are submitted by the community. They usually come from places like Twitter or Reddit. Then I manually review them to ensure everything looks good before pushing to the site, which is [findcool.tools](https://findcool.tools)

Even though this was just a fun random project I wanted to start, I decided to launch it on Product Hunt. Much to my surprise, we received #3 Product of the Day.

![findcool.tools product hunt award badge](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/kzjwitb7a4ro6dt2rzli.png)

Since then, I've been putting a little more time into it. We're almost at 150 tools submitted and over 150 [newsletter](https://findcooltools.beehiiv.com/) subscribers.

**Here's the tech stack I'm using for anyone interested:**

- Astro for the frontend
- Google Sheets for my database
- Google Forms for new tool submissions

Told you I was keeping the tech stack light... haha

All in all, this is turning into a fun project and I just wanted to spread the word that if you have a random idea, pursue it. You never know what will come out of it.

Thanks for taking the time to read this. You can find me over on [Twitter/X](https://twitter.com/johnwritescode_)

Have a tool you think would be a good fit for [findcool.tools?](https://findcool.tools) You can [submit it here](https://findcool.tools/tools).

APIOLOGY a PHP API light framework
Tags: api, php, backend, docker
Published: 2023-09-22 23:03:35

Just released a php api framework, to make things easy in order to handle backend requests in any host using php.

It can be found [here](https://github.com/m4r4v/apiology)

What I loved about it is the way it can handle http headers, including Origin, Methods and Authorization.

At the moment it just have BasicAuth and ApiKey available.

The versioning works great, no need to reinvent the wheel. To create a version is as easy as the following:

- Add version name and status to settings
- Create a folder with the Version Number i.e: v2
- Copy resources.php from v1 folder and paste it inside the new version folder.
- Use a Namespace according to the version i.e.: Apiology\Api\Resources\V2

for testing purposes, it has instruction on how to run a docker container, instructions and be read [here](https://github.com/m4r4v/apiology#readme)

Love to have a review about it and improvements are always welcome.

Thanks

What is JavaScript(and what can you do with it)
Tags: javascript, beginners, programming, webdev
Published: 2023-09-22 22:33:52

## What is JavaScript

JavaScript is one of the most popular and widely used programming languages in the world right now. It is growing faster than any other programming language and big companies like Netflix, Walmart, and PayPal build entire applications around JavaScript. 

And here is the average salary of a JavaScript developer in the United States. That is $72,000 per year according to glassdoor.com. 

So, it is a great opportunity to get a good job out of learning JavaScript. You can work as a front-end developer, a back-end developer or a full stack developer who knows both the front end and the back end.

[For the Full eBook, you can get it here](https://karlgusta.gumroad.com/l/edtbb)

Now the second question.

## What can you do with JavaScript

For a long time, JavaScript was only used in browsers to build interactive web pages. Some developers refer to JavaScript as a toy language. But those days are gone because of huge community support and investments by large companies like Facebook and Google.

This days, you can build full-blown web or mobile apps, as well as real time networking applications like chat and video streaming services, command-line tools, or even games. Here is an example:

![A JavaScript game](https://user-images.githubusercontent.com/33565767/228169522-7f5a15ac-3606-474f-8a57-43b1c6c84988.png 'A JavaScript game')

Happy Coding!
