PHP (Hypertext Preprocessor) is a popular server-side scripting language designed for web development. It allows developers to create dynamic and interactive web applications. Unlike HTML, which is static, PHP enables web pages to change based on user input, database queries, and other conditions.

MySQL Naming Conventions

What is MySQL?

MySQL is a freely available open source Relational Database Management System (RDBMS) that uses Structured Query Language (SQL). SQL is the most popular language for adding, accessing and managing content in a database. It is most noted for its quick processing, proven reliability, ease and flexibility of use.

What is a naming convention?

In computer programming, a naming convention is a set of rules for choosing the character sequence to be used for identifiers that denote variables, types, functions, and other entities in source code and documentation.

General rules — Naming conventions

Using lowercase will help speed typing, avoid mistakes as MYSQL is case sensitive.

Space replaced with Underscore — Using space between words is not advised.

Numbers are not for names — While naming, it is essential that it contains only Alpha English alphabets.

Valid Names — Names should be descriptive of the elements. i.e. — Self-explanatory and not more than 64 characters.

No prefixes allowed.

Database name convention

Name can be singular or plural but as the database represents a single database it should be singular.

Avoid prefix if possible.

MySQL table name

Lowercase table name

MySQL is usually hosted in a Linux server which is case-sensitive hence to stay on the safe side use lowercase. Many PHP or similar programming frameworks, auto-detect or auto-generate class-based table names and most of them expect lowercase names.

Table name in singular

The table is made up of fields and rows filled with various forms of data, similarly the table name could be plural but the table itself is a single entity hence it is odd and confusing. Hence use names like User, Comment.

Prefixed table name

The table usually has the database or project name. sometimes some tables may exist under the same name in the database to avoid replacing this, you can use prefixes. Essentially, names should be meaningful and self-explanatory. If you can’t avoid prefix you can fix it using php class.

Field names

Use all above cases which include lowercase, no space, no numbers, and avoid prefix.

Choose short names no-longer than two words.

Field names should be easy and understandable

Primary key can be id or table name_id or it can be a self-explanatory name.

Avoid using reserve words as field name. i.e. — Pre-defined words or Keywords. You can add prefix to these names to make it understandable like user_name, signup_date.

Avoid using column with same name as table name. This can cause confusion while writing query.

Avoid abbreviated, concatenated, or acronym-based names.

Do define a foreign key on database schema.

Foreign key column must have a table name with their primary key.

e.g. blog_id represents foreign key id from table blog.

Avoid semantically — meaningful primary key names. A classic design mistake is creating a table with primary key that has actual meaning like ‘name’ as primary key. In this case if someone changes their name then the relationship with the other tables will be affected and the name can be repetitive losing its uniqueness.

Conclusion

Make your table and database names simple yet understandable by both database designers and programmers. It should things that might cause confusion, issues with linking tables to one another. And finally, it should be readable for programming language or the framework that is implemented.

#Playstation7 #framework #BasicArchitecture #RawCode #RawScript #Opensource #DigitalConsole

To build a new gaming console’s digital framework from the ground up, you would need to integrate several programming languages and technologies to manage different aspects of the system. Below is an outline of the code and language choices required for various parts of the framework, focusing on languages like C++, Python, JavaScript, CSS, MySQL, and Perl for different functionalities.

1. System Architecture Design (Low-level)

• Language: C/C++, Assembly

• Purpose: To program the low-level system components such as CPU, GPU, and memory management.

• Example Code (C++) – Low-Level Hardware Interaction:

#include <iostream>

int main() {

// Initialize hardware (simplified example)

std::cout << "Initializing CPU...\n";

// Set up memory management

std::cout << "Allocating memory for GPU...\n";

// Example: Allocating memory for gaming graphics

int* graphicsMemory = new int[1024]; // Allocate 1KB for demo purposes

std::cout << "Memory allocated for GPU graphics rendering.\n";

// Simulate starting the game engine

std::cout << "Starting game engine...\n";

delete[] graphicsMemory; // Clean up

return 0;

}

2. Operating System Development

• Languages: C, C++, Python (for utilities)

• Purpose: Developing the kernel and OS for hardware abstraction and user-space processes.

• Kernel Code Example (C) – Implementing a simple syscall:

#include <stdio.h>

#include <unistd.h>

int main() {

// Example of invoking a custom system call

syscall(0); // System call 0 - usually reserved for read in UNIX-like systems

printf("System call executed\n");

return 0;

}

3. Software Development Kit (SDK)

• Languages: C++, Python (for tooling), Vulkan or DirectX (for graphics APIs)

• Purpose: Provide libraries and tools for developers to create games.

• Example SDK Code (Vulkan API with C++):

#include <vulkan/vulkan.h>

VkInstance instance;

void initVulkan() {

VkApplicationInfo appInfo = {};

appInfo.sType = VK_STRUCTURE_TYPE_APPLICATION_INFO;

appInfo.pApplicationName = "GameApp";

appInfo.applicationVersion = VK_MAKE_VERSION(1, 0, 0);

appInfo.pEngineName = "GameEngine";

appInfo.engineVersion = VK_MAKE_VERSION(1, 0, 0);

appInfo.apiVersion = VK_API_VERSION_1_0;

VkInstanceCreateInfo createInfo = {};

createInfo.sType = VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO;

createInfo.pApplicationInfo = &appInfo;

vkCreateInstance(&createInfo, nullptr, &instance);

std::cout << "Vulkan SDK Initialized\n";

}

4. User Interface (UI) Development

• Languages: JavaScript, HTML, CSS (for UI), Python (backend)

• Purpose: Front-end interface design for the user experience and dashboard.

• Example UI Code (HTML/CSS/JavaScript):

<!DOCTYPE html>

<html>

<head>

<title>Console Dashboard</title>

<style>

body { font-family: Arial, sans-serif; background-color: #282c34; color: white; }

.menu { display: flex; justify-content: center; margin-top: 50px; }

.menu button { padding: 15px 30px; margin: 10px; background-color: #61dafb; border: none; cursor: pointer; }

</style>

</head>

<body>

<div class="menu">

<button onclick="startGame()">Start Game</button>

<button onclick="openStore()">Store</button>

</div>

<script>

function startGame() {

alert("Starting Game...");

}

function openStore() {

alert("Opening Store...");

}

</script>

</body>

</html>

5. Digital Store Integration

• Languages: Python (backend), MySQL (database), JavaScript (frontend)

• Purpose: A backend system for purchasing and managing digital game licenses.

• Example Backend Code (Python with MySQL):

import mysql.connector

def connect_db():

db = mysql.connector.connect(

host="localhost",

user="admin",

password="password",

database="game_store"

)

return db

def fetch_games():

db = connect_db()

cursor = db.cursor()

cursor.execute("SELECT * FROM games")

games = cursor.fetchall()

for game in games:

print(f"Game ID: {game[0]}, Name: {game[1]}, Price: {game[2]}")

db.close()

fetch_games()

6. Security Framework Implementation

• Languages: C++, Python, Perl (for system scripts)

• Purpose: Ensure data integrity, authentication, and encryption.

• Example Code (Python – Encrypting User Data):

from cryptography.fernet import Fernet

# Generate a key for encryption

key = Fernet.generate_key()

cipher_suite = Fernet(key)

# Encrypt sensitive user information (e.g., account password)

password = b"SuperSecretPassword"

encrypted_password = cipher_suite.encrypt(password)

print(f"Encrypted Password: {encrypted_password}")

# Decrypting the password

decrypted_password = cipher_suite.decrypt(encrypted_password)

print(f"Decrypted Password: {decrypted_password}")

7. Testing and Quality Assurance

• Languages: Python (for automated tests), Jest (for JavaScript testing)

• Purpose: Unit testing, integration testing, and debugging.

• Example Unit Test (Python using unittest):

import unittest

def add(a, b):

return a + b

class TestGameFramework(unittest.TestCase):

def test_add(self):

self.assertEqual(add(10, 20), 30)

if __name__ == '__main__':

unittest.main()

8. Order of Implementation

• Phase 1: Focus on core system architecture (low-level C/C++) and OS development.

• Phase 2: Develop SDK and start building the basic framework for UI and input management.

• Phase 3: Work on backend systems like the digital store and integrate with front-end UI.

• Phase 4: Begin rigorous testing and debugging using automated test suites.

This comprehensive approach gives you a detailed idea of how each component can be built using a combination of these languages and technologies. Each section is modular, allowing teams to work on different aspects of the console simultaneously.

This structures the ground for other advantages which make it such a prominent choice for business software development. From websites to e-commerce solutions, from glossy new businesses to firmly established businesses, PHP is chosen solely or partially as the programming language for IT projects for the number of handy reasons.

PHP Open-source Nature Saves Budget:

The most great thing that successes developers’ and IT decision-makers’ dependability for PHP is that it is unreservedly accessible. PHP requires no download or permitting charges. It is open-source and is conveyed under the General Public License.

Added to apparent spending reserve funds, it additionally brings about a huge and dynamic universal community. This prompts constant upgrades in its functionality and in the noteworthy pool of assets and facilities. There are many PHP-based solutions whose viability has just been tried, so one doesn’t have to put assets in rehashing the wheel.

However, to be targeted it ought to be referenced that this fundamental preferred position of PHP can once in a while become the principle danger for the venture. Effortlessness and availability fundamentally bring down the edge of vocation section, which at times prompts diminished quality. In this way, the decision of an expert group with demonstrated mastery is an issue.

PHP consumes Less Time for Development:

PHP is a partially object-oriented language. It makes code reusability conceivable. Reusable PHP segments spare much time and exertion in the process of development. There are loads of PHP structures, as Symfony, CodeIgniter, Laravel, Joomla, WordPress, and so on. Every one of them conveys its own functionality and offers quick and secure development in explicit fields.

PHP was intentionally enhanced for making different web applications rapidly. It has such worked in capacities as getting to the GET and POST and working with HTML and URLs.

Since PHP is an implanted language, it effectively addresses joining issues. Despite the fact that it is normally prescribed to utilize it with HTML, PHP is effectively incorporated with JavaScript, WML, XML, and other programming languages. There are no issues with program presentation since every one of the contents is accumulated on the server-side.

Tasks regularly experience functionality changes sooner or later. With PHP, because of its dynamic nature, it is conceivable to execute them independently of the phase of development and without time-misfortune.

PHP-based Services are Easily Scalable and Well-documented:

As far as ROI, organizations often win when the IT arrangement is worked in iterations. It permits propelling various modules of the software logically and making essential corrections over the span of the development. With PHP, it is conceivable to create and bolster versatile IT anticipates and ceaselessly produce numerous pages with different settings.

PHP code is described by straightforwardness and phenomenal documentation. In this way, it sets aside less effort to comprehend in detail what is happening in the code — obviously, when it is elegantly composed.

LibreNMS provides the ability to automatically add devices on your network using Auto Discovery feature. All discovery methods run when discovery runs (every 6 hours by default and within 5 minutes for new devices Login to LibreNMS as the librenms user, and navigate to./opt/librenms This should be the home folder of librenms user. $  cd /opt/librenms The first thing to do though is add the required configuration options to config.php. Add SNMP Details To add devices automatically, LibreNMS needs to know your snmp details, examples of SNMP v1, v2c and v3 are below: // v1 or v2c $config['snmp']['community'][] = "my_custom_community"; $config['snmp']['community'][] = "another_community"; // v3 $config['snmp']['v3'][0]['authlevel'] = 'authPriv'; $config['snmp']['v3'][0]['authname'] = 'my_username'; $config['snmp']['v3'][0]['authpass'] = 'my_password'; $config['snmp']['v3'][0]['authalgo'] = 'MD5'; $config['snmp']['v3'][0]['cryptopass'] = 'my_crypto'; $config['snmp']['v3'][0]['cryptoalgo'] = 'AES'; These details will be attempted when adding devices, you can specify any mixture of these. Define you subnets to be scanned using: $config['nets'][] = '192.168.0.0/24'; $config['nets'][] = '172.20.4.0/23'; You can also run a manual SNMP Scan, the syntax is: $ ./snmp-scan.py [-h] [-r NETWORK] [-t THREADS] [-l] [-v] Example: $ ./snmp-scan.py 10.245.2.2 Scanning IPs: * Scanned 1 IPs: 1 known devices, added 0 devices, failed to add 0 devices Runtime: 0.39 seconds This device should appear under Devices > All Devices > Server on LibreNMS admin dashboard. Give it like 5 minutes to collect Server facts and start creating graphs, Logs and host events will start to appear as well.

LINUX MEMORY MONITOR FREE

Monit is a free open-source utility for proactively monitoring and managing system processes, applications, files, directories, and filesystems. To display the memory map of process ID, use the following command. You need to add PID along with pmap command to display the memory map of the given process. The pmap command is used to display the memory map of a process. pmap - Display the memory map of a process To display all information about CPU that mpstat can display, type $ mpstat -A 15. It shows reports for each available processor, starting with processor 0. Mpstat command is used to display processor-related statistics. mpstat - Display processor related statistics To display the network counter using sar, use the following command. To display the swap status, use the '-S- command along with sar command. Similarly, to display CPU average load, use the '-q' option with sar command. To display I/O device status, use the '-d' option along with sar command. Use -A option along with sar command to display detailed information about the I/O Devices, CPU, Memory, and Network statistics. On CentOS/RHEL/Fedora/Rocky Linux and AlmaLinux You can install the package using the following command. The SAR package is not found by default in the Linux system, but you can install the Sysstat package as SAR is part of sysstat. Aside from real-time system monitoring, SAR may also gather performance data in the background on an ongoing basis and analyze it to look for bottlenecking issues. System Activity Report (SAR) is a real-time system monitoring tool.
