How to Run MEGA VPN on Ubuntu Using wg-quick (The Fastest Method)

If you are a Linux user with a premium MEGA account, you might have noticed there is no official, standalone desktop app for MEGA VPN on Linux. However, because MEGA builds its network on the lightning-fast WireGuard protocol, you don’t need a bulky app.

You can launch your VPN directly from the terminal in seconds.

While many tutorials suggest complex setups using NetworkManager or moving system files around, the absolute fastest way to connect is by using the native wg-quick tool. Here is a step-by-step, human-tested guide to getting MEGA VPN running on Ubuntu with zero fluff.

Prerequisites: Install WireGuard

Before grabbing your configuration file, you need the standard WireGuard tools installed on your system. Open your Ubuntu terminal (Ctrl+Alt+T) and run:

Ref: https://www.wireguard.com/install/ 

 sudo apt update  
 sudo apt install wireguard openresolv -y  

Note: We include openresolv here because it automatically manages your DNS settings when the VPN switches on, preventing any accidental DNS leaks.

You Probably Don't Need Obsidian: Here's When You Shouldn't Use It

When Not to Use Obsidian: Why You May Not Need a Second Brain

Obsidian is one of the most powerful note-taking and knowledge-management applications available today. It can help you connect ideas, build a personal knowledge base, organize research, and create what productivity enthusiasts often call a “second brain.”

But there is a question that gets surprisingly little attention:

When should you NOT use Obsidian?

After spending considerable time exploring Obsidian tutorials, workflows, plugins, backlinks, graph views, and various “second brain” systems, I came to a fairly simple realization:

Obsidian is not automatically useful just because it is powerful.

In fact, for some people, using Obsidian can introduce more friction than value.

You may not need a second brain. You may simply need to think, decide, and get things done.

What Is Obsidian Actually For?

Obsidian is a local-first Markdown-based knowledge-management and note-taking application. One of its defining features is the ability to link notes together, allowing you to create a network of interconnected ideas.

This makes Obsidian particularly attractive to people who:

• Think through writing

• Conduct extensive research

• Write articles, books, or academic papers

• Need to retain large amounts of information

• Frequently revisit old ideas

• Want to connect concepts across different areas

• Enjoy building personal knowledge systems

For these users, Obsidian can be incredibly useful.

But there is an important distinction:

A powerful tool is not necessarily the right tool for everyone.

[SOLVED] - Install phpMyAdmin & LAMP on Ubuntu 20.04 Desktop

Install phpMyAdmin & Linux, Apache, MySQL/MariaDB & PHP [LAMP] on Ubuntu 20.04 desktop.

Below you will find the instructions that I myself have tried and successfully implemented on my system.

 1. Install Apache Web Server

 sudo apt update  
 sudo apt install apache2  

2. Install MariaDB

 sudo apt install mariadb-server  
 sudo apt install mariadb-client  

After that, run the commands below to secure the MariaDB server by creating a root password, disallowing remote root access removing anonymous, and more.

 sudo mysql_secure_installation  

 If you've just installed MariaDB, and haven't set the root password yet, you should just press enter here.  
 Enter current password for root (enter for none): PRESS ENTER  
 Switch to unix_socket authentication [Y/n] n  
 Change the root password? [Y/n] n  
 Remove anonymous users? [Y/n] y  
 Disallow root login remotely? [Y/n] y  
 Remove test database and access to it? [Y/n] y  
 Reload privilege tables now? [Y/n] y  
 All done!  

3. Install PHP

 sudo apt install php7.4 php7.4-common php7.4-mysql php7.4-gmp php7.4-curl php7.4-intl php7.4-mbstring php7.4-xmlrpc php7.4-gd php7.4-xml php7.4-cli php7.4-zip  

4. Install phpMyAdmin

 sudo apt install phpmyadmin  

When prompted to choose the web server, select apache2 and continue.

   

When prompted again to allow web config-common to install a database and configure select Yes and press ENTER.

Then type and confirm a password.

After installing phpMyAdmin, open your web browser and browse to the server hostname or IP address followed by /phpmyadmin.

 http://localhost/phpmyadmin  

If you encounter the following error implement the solution below to resolve the issue:

ERROR: mysqli_real_connect(): (HY000/1698): Access denied for user 'root'@'localhost'

Open your terminal and run the following commands:

 sudo mysql -u root  

 use mysql;  
 update user set plugin='' where User='root';  
 flush privileges;  
 \q  

Now the LAMP cum phpMyAdmin should be working for you.
