FOSS Advent Calendar - Door 13: Screen-Mirroring & Recording with scrcpy
Today’s tool is scrcpy, a powerful open-source utility that lets you mirror and control your Android device from your PC via ADB (Android Debug Bridge) over USB or Wi‑Fi.
With scrcpy, you can see your phone screen on your desktop and control it directly from your PC using your mouse and keyboard. You can also record screencasts from the mirrored session, perfect for tutorials, capturing gameplay, or streaming mobile apps, all without installing anything on your phone.
CLI-friendly and lightweight, scrcpy gives you full PC-based control over your device: navigate, type, launch apps, or record everything from your desktop. No bloated software, no intrusive permissions.

As a developer, which part of your workflow would scrcpy improve the most? Testing, debugging, or presenting your app?

"The just command runner is a Rust-based utility that just does one thing and does it well: it reads recipes from a text file (aptly called a "justfile"), and runs the commands from an invoked recipe."
FOSS Advent Calendar - Door 12: Plotting Like a Pro with Gnuplot
"Reports of my death have been greatly exaggerated."
This quote fits perfectly for Gnuplot, a classic FOSS plotting engine that’s still alive, powerful, and incredibly useful for creating beautiful scientific and mathematical visuals directly from the command line.
Gnuplot can generate 2D and 3D plots, animate datasets, visualize functions, and export to nearly any format you might need: PNG, SVG, PDF, EPS, and more. And one of its greatest strengths?
You don’t need a whole Python stack, dozens of libraries, or virtual environments just to make a graph. Gnuplot runs instantly, scriptable, lightweight, and beautifully minimal.
Whether you’re analyzing experimental results, visualizing parametric curves, or just plotting a weird math idea you had at 2 AM (we’ve all been there), Gnuplot gets it done fast and clean.
Pro tip: try rendering a dramatic 3D surface plot or a festive math figure, like a parametric Christmas tree. Gnuplot makes it surprisingly easy to turn equations into art.
Link: https://sourceforge.net/p/gnuplot/gnuplot-main/ci/master/tree/
What’s a plot you’d LOVE to generate with Gnuplot, serious or purely nerdy?

FOSS Advent Calendar - Door 10: Using Your Phone as a Microphone with Audiosource
Today we explore Audiosource, a nifty FOSS tool that lets you use your Android phone as a microphone for your computer.
Audiosource works via ADB (Android Debug Bridge), streaming audio from your device over USB or Wi-Fi directly to your Linux system. This is perfect if you want a quick wireless mic, don’t have a dedicated microphone, or just love tinkering with FOSS tools.
Everything runs from the command line, giving you full control and total nerdy satisfaction. Plug in your phone, run the command, and your device becomes a fully functional mic!
Pro tip: try combining it with recording or streaming software, or even some AI audio processing, the possibilities are endless.

FOSS Advent Calendar - Door 9: 3D Rendering with POV-Ray
Today we explore POV-Ray, a powerful FOSS tool for creating stunning 3D graphics.
POV-Ray stands for Persistence of Vision Raytracer. It allows you to describe complex 3D scenes in a text-based scene description language and render them into high-quality images. You can create anything from simple geometric shapes to intricate molecular structures or artistic compositions.
It’s perfect for nerds, FOSS enthusiasts, or anyone who wants to combine programming and art to produce beautiful visuals. POV-Ray works entirely via the command line, so you can automate renders, tweak parameters, and experiment endlessly with light, textures, and camera angles.
Pro tip: try rendering a molecule, a futuristic scene, or a holiday-themed object in 4K resolution, the results are mesmerizing!
For this example, I have rendered the HIV Protease Inhibitor from the RCSB PDB entry 1HVR (Rational design of potent, bioavailable, nonpeptide cyclic ureas as HIV protease inhibitors).

I may have needed to introduce a sibling to the CLI only two weeks after installing Fedora Linux. An update was forcibly terminated. (powered off the laptop).
I had the chance to be Linux tech support over the phone, and have an update completed via chroot.
While this did not solve the problem in full, it was fun to know that I could have gotten that far over the phone. Also I learned that `lsblk -f` give a detailed look at the filesystem.
Oh joy, another riveting tale of web devs forgetting that not everyone worships at the altar of #JavaScript. 😴🔥 Just what we needed: a command-line #challenge that ironically requires more clicks than key commands. 🖱️⌨️ Turns out, the real challenge is enduring the irony! 😂✌️

FOSS Advent Calendar - Door 7: Enhancing Images with Real-ESRGAN
Today we explore Real-ESRGAN, a powerful FOSS tool for upscaling and improving image quality.
The name stands for Enhanced Super-Resolution Generative Adversarial Networks, highlighting the AI-powered approach behind the magic.
Real-ESRGAN can take a low-resolution or slightly blurry image and enhance it, adding details that make it look sharper and more natural. It works via the command line, where you provide an input image and get an upscaled output image. You can instantly compare the results in your favorite image viewer, like EOG.
It’s perfect for nerds, FOSS enthusiasts, or anyone who wants to improve images without relying on commercial software.
Pro tip: try upscaling an old screenshot or a tiny meme, the results are often hilarious and impressive at the same time!

As a WordPress website administrator, having a WAF is due diligence. However, as an admin, it's more common to perform actions that trigger a firewall block. When that happens, the last thing you want is to call your web host and spend the next hour escalating your case to regain access. Here's a quick way to bypass your firewall through the WP-CLI.
