HIRING SBC/Linux Engineer — Create Lightweight OS Image that Boots into Fullscreen App

I’m looking for an experienced SBC/Linux integration engineer to create a minimal, stable Linux image for a Raspberry Pi / RK3588-class board that boots directly into a fullscreen application (Godot).

This is essentially a custom kiosk-mode SBC environment, not a full OS build.

Environment must be locked down to kiosk mode no desktop, no browser, no shell access, no user-initiated application switching.

⸻

What I Need

A lightweight Linux image that:
• boots directly into a single fullscreen app (via systemd)
• auto-restarts the app on crash/freeze
• is optimized for GPU/CPU performance on low-power ARM boards
• locks to a 1280×800 display
• supports audio output
• includes simple brightness + volume controls
• is stable under long-duration runtime (3–6+ hours)
• includes basic logging + crash output
• supports a simple USB update method (drop-in app file replacement)



Target Hardware
• Raspberry Pi 4/5, or
• RK3588-based SBC

(Plan on testing functionality on the above hardware prior to delivery.)



Requirements

You should have experience with at least one of:
• building kiosk-mode systems
• Raspberry Pi OS / Debian / Ubuntu / DietPi / Armbian customization
• systemd service creation
• GPU driver configuration on ARM
• kiosk environments (digital signage, arcade cabinets, etc.)
• optimizing thermal / power behavior on SBCs
• headless or minimal-desktop Linux images



Deliverables
• bootable .img file
• systemd service(s) for auto-launch + auto-restart
• GPU/CPU tuning (governor, throttling behavior)
• resolution + display config
• audio config
• brightness/volume noscripts
• instructions for app updates
• debugging/logging notes



Nice to Have
• experience with Godot export pipelines
• experience with KMS/DRM configuration
• experience with ARM GPU quirks (Mali/Broadcom)

Canonical ips bypassing wireguard tunnel - Mint

Hello gentlemen, good morning.

I'm using WireGuard to connect to another device and use its internet connection to access the internet from that country.
I configured WireGuard to capture all traffic and send it to this peer; however, I don’t know why some Canonical requests are bypassing the WG interface.
Any ideas?

Opensource app: Pro Audio Config

A professional audio configuration tool for Linux systems, made in Rust + GTK3. Still in WIP. MIT licensed.

Provides a simple graphical interface to manage PipeWire and ALSA audio settings. Finally, an easy way to configure sample rates, bit depths, and buffer sizes without digging through config files. More will come further. - Github repo link

After 10 years of using Fedora and other Linux distributions, I realized we're still missing a fundamental tool: a simple, graphical way to configure professional audio settings. In 2025, manually editing configuration files shouldn't be the only option for adjusting basic audio parameters.

A reflection from a Linux fan.

I wanted to post this in Linuxsucks sub but it got rejected (idk quite why). So ill try here so its not wasted.

Hi, i'm from a third world country.
My machine is a Laptop HP Pavilion TS 10. You can search its specs online. I'm glad I have linux bc this laptop comes with windows 8.1 and ITS A NIGHTMARE. Opening a right-click menu sometimes could take minutes. Opening a browser? Death. Seriously it was bad.

I can even edit video in my laptop with Kdenlive! And I can have a browser with several tabs open at the same time! (Though, I edit in a 480p video resolution that its borderline unacceptable for today standards, but its better than nothing, in windows I could not have done nothing, and my last video was still well received). My distro is Debian 13.

Performance its the only thing (according to my user needs) where Linux beats the SHIT OUT of Windows. For a lot of other features its worse and outdated to today standards (though Mint has done a great work for making you use the terminal less, but it is still not perfect).

Microsoft has put a standard of the knowledge you need for using your computer, and that standard is not going to dissapear. We cant really expect a lot of people to use the terminal when they would need a video tutorial and/or get help from the 'tech-savvy' member of their family for something that could be solved with gui in windows. Is that because they are dumb? NO! Its because nobody is born knowing everything.

Like imagine you are a newbie and your distro comes with openbox and you need to configure its hotkeys. You search on internet and your solution is in editing the rc.xml. A text file. with a LOT of text within. And kinda hard to read...

Linux is not only for programmers, I know, but in this situation you would need to be familiar with certain aspects of programming logic in order to edit this file without having done it before. Knowing that the shit that haves this weird <> symbols are "open and close tags". The computer needs then bc thats how it can differentiate between one option and another. Also, be sure that you write those tags respecting uppercase and lowercase bc the computer is not a human, letters are actually numbers and 'a' is a different number than 'A'. AND the closing tag needs the '/' symbol bc if not you are NESTING another tag.

???

And I say this as a Linux lover. This is not a problem for me bc I am (not beating the 'Linux is for programmers' allegations) a programmer and on top on that I am a tech enthusiast. I also from some time ago I have fallen in love with its philosophy, so I am not moving from Linux. But for a non-nerd user, I think we still have things to do.

A lot of people can learn, sure. But we can't really ask a lot of people to do it, bc again, Microsoft has put a big standard for user experience.

So, if a Linux dev is reading this: please consider making a GUI for your utility. I think tha could be a grain of sand for making Linux more comfortable.

And sorry if I come off as a bit smug or smth. My english expression abilities may not be the best, and I assure you my intention is not hating or creating animosity.

HP/DELL disable HEVC on some of their laptops

Dell and HP are apparently shipping (some) laptops with HEVC hardware decoding disabled - see the writeup in Ars.

These models are mentioned:

HP ProBook 460 G11
HP ProBook 465 G11
HP EliteBook 665 G11
Dell 16 Plus 2-in-1

It's not clear how this is done. I would hope software, but both these companies have disabled stuff in hardware before.

Can anyone with (access to) one of these confirm if HEVC hardware playback works in Linux?

Built a tiny high-performance telemetry/log tailing agent in Zig (epoll + inotify). Feedback & contributors welcome

I’ve been hacking on a little side-project called zail — a lightweight telemetry agent written in Zig that watches directories recursively and streams out newly appended log data in real time.

Think of it like a minimal “tail-F”, but built properly on top of epoll + inotify, no polling, and stable file identity tracking (inode + dev_id). It’s designed for setups where you want something fast, predictable, and low-CPU to collect logs or feed them into other systems.

# Why I’m posting

I’m looking for early contributors, reviewers, and anyone who enjoys hacking on:

epoll / inotify internals
log rotation logic
output sinks (JSON, TCP/UDP, HTTP, Redis, etc.)
async worker pipelines
structured log parsing
general Zig code quality improvements

The codebase is small, easy to navigate, and friendly for new Zig/system-level contributors.

# Repo

If you like low-level Linux stuff or just want a fun project to tinker with, I’d love your thoughts or contributions!
