If you're running a lean Windows build like tiny11, or something simply corrupted your installation, you might run into errors like these when trying to launch a game:

JetBrains Toolbox is the official manager for installing and updating IDEs like IntelliJ IDEA, PyCharm, CLion, and others.
It makes life a lot easier — but installation can be confusing the first time.
For example, I used to download the .tar.gz, extract it into Downloads, run it, and later delete the folder — which, of course, broke everything because the app could no longer find its binary.

Here’s a simple and direct guide to properly install Toolbox on Linux Mint (and it works the same for Ubuntu/Debian in general).

The Common Problem​

How many times have you gone through this frustrating situation?

1. You enable WiFi debugging on your device
2. You scan the QR code (or enter the pairing code) in Android Studio
3. It works for a while — until you restart the device or switch networks
4. Then you lose the connection and have to repeat the entire process
5. Or sometimes the QR code simply refuses to work

Wi-Fi debugging in Android Studio, when properly configured, offers a smoother and more productive development experience.
The key is understanding the difference between pairing and debugging ports, and using the adb pair command to create a persistent trust link between your device and your computer.

Following this guide, you’ll never need to scan QR codes again or deal with unstable connections.
The command-line pairing process is faster, more reliable, and gives you full control over the connection.

Context​

So, I was trying to install Battlefield 2042 and found out that the latest update requires Secure Boot to be enabled.
No big deal — I use dual boot (Zorin OS for work, Windows 10 for gaming), so I jumped into my X99 Qiyida D4 BIOS and enabled Secure Boot.

The result?
Linux completely refused to boot and instead displayed this lovely message:

“Invalid signature detected. Check Secure Boot policy in Setup”

Great. Here we go again...

Hey there! 👋
Today I’m going to teach you (or at least try) how to add a theme to GRUB, so every time you boot your PC or switch operating systems, you don’t have to stare at that ugly default screen anymore.
Let’s turn this:

After​

After almost 10 months without posting anything useful, I’m finally back — and this time, I’m going to show you how to make your terminal much more productive (and honestly, prettier).
Let’s get straight to the point — here’s what we’re going to cover:

• Installing Hyper.js
• Configuring the Catppuccin Theme
• Installing Zsh
• Installing Oh My Zsh
• Installing ZInit
• Installing the Fira Code Font
• Installing Spaceship
• Preview
• Useful Links

For reference, I used Zorin OS Core (fresh install) while writing this tutorial.

Before we begin, I should mention that I’m still a beginner in Android development — and yes, I still code on my phone! So it won’t be possible to show examples using Android Studio.

Hello, Android developers! 👋
Today we’re going to understand what fragments are and how they can transform the way we design interfaces in Android applications.

Data structures are a fundamental concept in building algorithms and programming languages, as they are responsible for organizing and manipulating data more efficiently in the computer's memory — which can lead to the optimization of processes and operations.
