The advantages, complexity, and role of the merge sort algorithm in LAN management software
Published: 2023-07-10 03:37:42

In LAN management software, the merge sort algorithm is capable of efficiently and stably sorting large-scale data, supporting distributed processing and scalability, thereby enhancing the performance and efficiency of LAN management software. Through the merge sort algorithm, data in the LAN can be better organized and managed, providing more reliable and efficient network management services.

The merge sort algorithm has the following advantages in LAN management software:

Stability: The merge sort algorithm is a stable sorting algorithm that maintains the relative order of equal elements. Maintaining data stability is crucial for accurate data analysis and processing in LAN management software.
Efficiency: The merge sort algorithm has a time complexity of O(nlogn), making it perform well when dealing with large-scale data. In LAN management software, there is a need to process a large amount of device information, network traffic data, etc. The merge sort algorithm efficiently sorts this data.
Scalability: The merge sort algorithm has good scalability and can handle large-scale data. In LAN management software, the network size and data volume may continue to grow, requiring a sorting algorithm capable of handling large-scale data. The merge sort algorithm can handle the increasing data volume while maintaining good performance and efficiency.
The complexity of the merge sort algorithm in LAN management software is mainly reflected in the following aspects:

Time complexity: The merge sort algorithm has a time complexity of O(nlogn), where n is the size of the data to be sorted. When dealing with large-scale data, the algorithm’s runtime can be relatively long.
Space complexity: The merge sort algorithm requires additional space to store temporary data and result data, resulting in a space complexity of O(n). When processing large-scale data, a significant amount of memory space may be needed.
The role of the merge sort algorithm in LAN management software primarily lies in sorting and consolidating data:

Data sorting: LAN management software requires sorting of device information, network traffic data, etc., for better data analysis and processing. The merge sort algorithm efficiently and stably sorts this data, providing an ordered dataset.
Data consolidation: LAN management software often needs to consolidate data from different devices and different sources of network traffic. The merge sort algorithm can be used to merge multiple sorted lists or datasets, assisting in the consolidation and processing of data from various sources.
In summary, the merge sort algorithm has the advantages of stability and efficiency in LAN management software. It can sort and consolidate large-scale data, providing an ordered dataset to support data analysis and processing. However, the algorithm’s time complexity and space complexity need to be considered, as processing large-scale data may require more computational resources and memory space.

Installing PHP Unit
Tags: phpunit, php, tutorial
Published: 2023-07-10 03:00:00

Disclaimer: That's another of those posts where my main goal is to register for my future reference and avoid spending lots of time "googling" to remember. 

With some hope, this can somehow help someone else too!

## Install the PHPUnit library

For tests, I will use the PHPUnit library installed using Composer.

`composer require phpunit/phpunit`

## Create phpunit.xml

We can create with the command:

`vendor/bin/phpunit --generate-configuration`

## PHPUnit Code Coverage

PHP Code Coverage is a library that provides collection, processing, and rendering functionality for PHP code coverage information.
You can add this library as a local, per-project dependency to your project using Composer:

`composer require phpunit/php-code-coverage`

If you only need this library during development, for instance, to run your project's test suite, then you should add it as a development-time dependency:

`composer require --dev phpunit/php-code-coverage`

### XDebug

Xdebug is an extension for PHP and provides a range of features to improve the PHP development experience, one of them is to provide **Code Coverage Analysis** to show which parts of your code base are executed when running unit tests with PHPUnit.

It is necessaire to active Xdebug on your PHP. More details on [Xdebug](https://xdebug.org/) official documentation.

### Generate reports

`vendor\bin\phpunit --coverage-html < directory > `

## Documentation

PHPUnit documentation is available [here](https://docs.phpunit.de/en/10.0/index.html).

C++, Preprocessor directives: #define, #ifdef...
Tags: define, ifdef, macro, cpp
Published: 2023-07-10 02:12:48

Even though #define, #include, #ifdef, #ifndef, #endif.. are very common but when i try a hackerrank problem, the term "Preprocessor directives"  sound unfamiliar to me. So i just summarize about it here.
**Definition:** Preprocessor directives are lines included in the code of programs preceded by a hash sign (#). These lines are not program statements but directives for the preprocessor. The preprocessor examines the code before actual compilation of code begins and resolves all these directives before any code is actually generated by regular statements
Some types of preprocessor directives that I frequently use :
**Macro Definition**

```cpp
#define foreach(v,i) for(int i = 0; i< v.size();i++)
#define toStr(S) #S  // to string
#define getmax(a,b)  ((a) > (b)) ? (a): (b)
#define FUNCTION(name, operator) int name(int a, int b){if(a operator b)return a;else return b;}
FUNCTION(maximum, >)
FUNCTION(minimum, <)

void testFunc() {
    vector<int> iV = { 3,5,7,8,3,5,4 };
    foreach(iV, k) {
        cout << " " << iV[k];
    }
    cout << endl;
    int a = 9;
    int b = 52;
    int min_val = minimum(a, b);
    int max_val = getmax(a, b);
    cout << "Debug info : " << endl;
    cout << "  File : " << __FILE__ << endl;//predefined macro for debug
    cout<<"  Line : " << __LINE__ << endl;
    cout << endl;
    cout << toStr(Min Value = ) << min_val << endl;
    cout << toStr(Max Value = ) << max_val << endl;
}
```
**File Inclusion** : `#include "header.h"`

**Conditional Compilation**

```cpp
#define DEBUG 
void test_define() {
#ifdef DEBUG
    cout << "Debug mode enabled." << std::endl;
#else
    cout << " not define DEBUG " << endl;
#endif
#ifndef RELEASE
        cout << "Not in release mode." << std::endl;
#endif
}
```
There are others directives like :

```
#undef
#pragma startup
#pragma exit
...
```
but i never use except `#pragma once` to prevent multiple inclusions of the file

Build a Decentralized Reddit on DeSo and Get $1M in Funding
Tags: cryptocurrency, web3, blockchain, opensource
Published: 2023-07-10 00:22:19

My name is Ash, and I work for the cutting-edge [DeSo](https://www.deso.com/) Foundation, a custom-built layer-1 blockchain designed to scale decentralized social media applications to billions of users.

I'm sure everyone is aware of the Reddit API fiasco and also what's going on with social media today. 

Because of that, we're offering up to $1M in funding for a team interested in building a decentralized Reddit competitor on DeSo.

And that is from us personally. This project will likely get visibility in front of our investor network as well (a16z, Sequioa, Coinbase Ventures, and many more!), so it could potentially end up being more than $1M.

Here's more info:

We live in a world where only 3 - 5 corporations control what we see and do online. They also own our content and social graph, with no clear path to monetization.

It's time to change that and break free!

The best part about DeSo is that you don't need to know or learn solidity or Rust to start building. You can use your web2 skill set to build on DeSo, drastically reducing the development time of building a killer app.

If you're interested in learning more about DeSo and its tech stack, here are a few resources:

10 Python Code Habits You Must Avoid for Efficient Programming
Tags: python, development, datascience, ai
Published: 2023-07-09 23:57:28

Python has gained immense popularity among developers worldwide due to its readability and extensive range of libraries and frameworks. However, like any programming language, Python is not immune to mistakes and pitfalls.

In this article, we’re going to explore 10 examples of bad code habits in Python. These examples will showcase common writing errors, inefficient practices, and potential pitfalls that can cause problems and make your Python code less efficient. Whether you’re a coding newbie or a seasoned programmer, this article is packed with examples of what NOT to do when writing code in Python.

## 1. Mixing different naming conventions
Mixing different naming conventions to define different parts, such as using a camel case for functions and a Pascal case for variables makes the code inconsistent and harder to read.

```
def myFunction(num):
    MyVar = num/3.5
    return MyVar
```
It’s better to follow a consistent naming convention throughout the source code to improve code readability and maintainability. One of the most used and widely adopted conventions is snake_case where identifiers are written in lowercase with underscores separating different words.

```
def my_function(num):
    my_var = num/3.5
    return my_var
```
## 2. Ignoring code comments
Leaving incomplete or misleading comments, or not providing any documentation can impact the understandability of the code and create confusion among fellow developers.
```
import re
text = "abc@xyz.com for further information."+\
        "You can also give feedbacl at feedback@xyz.com"

emails = re.findall(r"[a-z0-9\.\-+_]+@[a-z0-9\.\-+_]+\.[a-z]+", text)
print (emails)
```
Clear comments and comprehensive documentation provide essential context and ensure smooth collaboration between developers. It also reduces the time and effort required for understanding the code. By documenting the code properly developers can ensure that future changes and updates can be implemented efficiently, which leads to a more robust and maintainable end product.

A Guide On How To Become A Front-End Developer
Tags: beginners, webdev
Published: 2023-07-09 23:25:29


   In this guide we will learn what front-end development is, the skills needed, and how to get into front-end development. 


**What is frontend development?**
 Frontend development is an aspect of software engineering that mostly deals with the user interface. Most frontend developers learn HTML, CSS, and Javascript, the three most important tools used in making websites, others might also learn frameworks such as tailwindcss, react js, angular bootstrap, and so on. Frontend developers also use tools such as Git and GitHub. Git is a version control system that works hand in hand with Github which is a hosting server site for managing and storing codes.
    In this how-to guide, we will learn what these tools are and where to learn them.
**What skills do front-end developers need**?
Front-end developers are much needed in our world today. The basic skills needed are as follows: 
**HTML(Hypertext Markup Language)**: This can be said as the basics of all websites. It is the building block of all websites which can perfectly be known as the skeleton of the sites. It deals with written words, their positions, etc.
**CSS(Cascading Stylesheet)**:
This is used to style up the website, it can be the background color of the site, the color of texts, images, font style, sizes, etc. It's used in making websites more beautiful. It's more like putting a skin/body on a skeleton. 
**JavaScript**: Javascript simply makes websites more interactive, it adds more functionality to sites. Deals with how sites behave such as the user clicking on a like button etc.

 **Steps of becoming a frontend developer**


**Step 1: Planning**
  Make a plan on how you want to get into front-end development, it can be by taking a course online, joining a boot camp, or going to a university to get a diploma or degree certificate. Online courses have become popular over the years and the following are some online courses to learn from are as follows:

- FreeCodeCamp
- Codecademy
- Web3
- Microverse
 
You can also self-learn this from youtube channels. Recommended ones are:
Simplilearn

- Super simple
- FreeCodeCamp
- CodewithMosh


**Step 2: Build Projects**
   Practice makes perfect. You can build projects to gain experience. These sites are my favorite for gaining experience in web development.

- Codewars
- Hackerank

**Step 3: Build Your Portfolio**
    Begin to build your portfolio by working on your favorite. Work on what you love the most, it could be working on your favorite project such as a restaurant site, movie site, to-do list, weather app, etc.

**Step 4:  Apply for jobs/internships**
   You can apply for jobs or internships to gain much more experience on the job. Make sure you go through some coding challenges.  I will recommend Leetcode interview challenges.

Hope this guide helped you to become the front-end developer you've dreamt of.
