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.

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

I'm worried about Flathub packaging and reviewing
I'm a huge fan of Atomic (immutable) distros. I love the way it's more build in layers. Like your OS is basically an image, that can be pushed towards any device pretty easily, and reverting that image is pretty easy.
On the desktop I use Fedora Kinoite, and used Silveblue, Aeon and uBlue as alternatives. I'm pretty comfortable in using Flatpaks instead of installing packages, and for CLI stuff it's mostly Podman to run containers.
However their is something that makes me feel worried. A lot of packages on Flathub are community supported, instead of the actual developer(s) providing the build. This means you'll end up in the same situation as using a traditional package provided by the distro. I'm already seeing people dropping maintenance because of lack of interest, difficulties to break the sandbox when needed (IDE tools for example) and depencies that never get updated (even developers is using different ones).
It makes me think if Flatpaks are really the answer. I love the idea of them, but I always compared them to Docker images but for usage with a GUI. But when you look more closely, they are pretty much the same as any other distro package (or worse when they break the sandbox to make it work). I know it's offers SDKs and other integration, but I'm worried Flatpak doesn't offer anything useful for developers right now? Why aren't developers picking up Flatpaks?
I would really like to see some different approach, especially on Flathub. If it's not maintained by the developers, why not list the people that actually do? Why don't show any information on Flathub of the actual dep tree? Why not provide easy version control, multiple channels (like F-Droid on Android), etc. it's all possible, but it seems very pushed away. For the manifest, I have to go to another tab, and lookup the GitHub repo for it. Many things like SDKs aren't even listed.
I know an user needs to have an easy approach, but it feels way less intuitive compared to other tooling.
Yes I'm overreacting, but Flatpaks aren't apps you'll find in the Apple App Store. They are 90% unofficial at the moment, meaning the original developer doesn't give any support in most cases. It makes me feel no one is adopting them, while everyone is creating their own container images. I know it's different tech, but I don't understand it.

Calling on whatsapp finally on linux?
Whatsapp has migrated its windows client from a native client to a webview wrapper, but this version of whatsapp web does support calling unlike the browser whatsapp web.
Since the new client is web based shouldn't it be easy to port to linux or run using wine so that Linux users can finally have calling on whatsapp?

rsync -avP for large transfers. Going from a blind cp that could silently fail for hours to seeing the progress and file list in real-time was a game-changer.A close second is

App development for linux
Hi folks, hope all are well..
I have flirted with linux for years now, running mint on an older laptop and trying to get into it on desktop, then falling back to the dark side (Win) to play games, c++ development and some apps that just womt run - eventually just reverting away from linux as i found myself booting win all the time (dual boot is lame - too easy to just give up)
Thanks to valve gaming is better than ever (and still improving), ms going the other direction and recent events makimg me run linux only and take the bull by the horns (but ms behaviour is off topic).
I wanted you to have an idea where i come from and why i ask this question. I learned the basics of c++ from books and i learned Win32 from help files, internet dev sites and example code. Then i started learning sdl (and it seems sdl2 at the same time) - now their going sdl3 and im out of date again, oh lordy..i have struggled over the years being both student and tutor not knowing enough to be tutor
Now i find myself on linux with no win32, no commom controls for gui and a big heap of libraries out there, glade, gtk, gtkmm, qt and many more. Im not a tutor and im confused. Many say qt, but many talk of licencing issues.
What im looking to do is create a window (maybe sdl2, maybe have to learn sdl3?) and attach controls: text, edit, buttons, tabs, lists, etc.. specifically im looking to have tabs (loke tabs in firefox, but permanant with edit, buttons and lists within them).
Admittedly, ive not actually coded that much lately and a tad rusty, plus ive landed in a place where the tools i know dont exist - at least in a way i know..
Ive looked for forums and while ive found a few, theyre either general linux topics, deep development (kernel, etc) or distro level aimed at using a particular distro (i chose to install pop os after problems with fedora). Nothing that seems to suit whay im trying to do.
Is there a logical place to get help with creating gui apps on linux (with controls?) or swim the murky waters till you learn or drown? Is 'r linux' even a good place to start for advice?
I thank im advance for any that took the time to actually read this and for any advice that may be given as atm im really quite stuck.. maybe im too out of date with what i think i know - computers and development move on so fast..

SumatraPDF Reader on Linux (Basic Guide)
I've decided to make this guide due to one of my saddest "let go" from ditching Microsoft Windows, the Sumatra PDF Reader.
Before reading please keep in mind two things:
1. I'm a new Linux user (been using for almost a year) so any mistake that seems silly may come from that;
2. English is not my primary language, so any corrections are welcome, i won't feel offended in any way.
Sumatra PDF has been a part of my life for many years now, i use it on my work pc (Windows), and have used on my personal pc (while i still used windows) as well. Switching to Linux made me realize that Sumatra has no equal to this date (for my specific use). I liked Okular but the right click functions of Sumatra for zooming and panning a document, is, in my opinion, unmatched.
So here is how i managed to use Sumatra on Linux in a way that satisfy my needs and takes advantage of most of Sumatra features.
# System used:
OS: Fedora Linux 42 (KDE Plasma Desktop Edition) x8664
Kernel: Linux 6.17.8-200.fc42.x8664
Shell: bash 5.2.37
Display (BOE0C29): 1920x1080 @ 144 Hz (as 1536x864) in 16" Built-in
DE: KDE Plasma 6.5.2
WM: KWin (Wayland)
WM Theme: plastik
Theme: Windows (BreezeDark) Qt, Breeze GTK3/4
Icons: breeze-dark Qt, breeze-dark GTK3/4
Font: Noto Sans (10pt) Qt, Noto Sans (10pt) GTK3/4
Cursor: breeze (18px)
Terminal: konsole 25.8.3
# Installation:
1. Download the latest Sumatra installer (haven't tried the portable or pre-release versions)
2. Install the .exe installer using wine (in my case i just double clicked the .exe installer from my download folder)
You should now be able to open and use it! And get frustrated for not seeing the tabs (although they are there and can be switched using crtl+tab). Don't worry we'll fix that.
# Configuring it to display the tabs:
1. Open
2. Now on the Applications tab select the SumatraPDF.exe and switch to the Graphics tab. Uncheck the "Allow the window manager to decorate the windows".
Sumatra displaying tabs and the noscript bar on Linux.
# Tips:
You can also set a Special Window Setting to hide the noscript bar.
# Any tips are welcome:
When right clicking a tab and choosing
I hope this guide finds you well and make you feel as welcome as i felt with the guides i've encountered when switching OS.

linux always has the most random quality of life features that you would never get in windows
I just discovered that my 15 y.o laptop with AntiX linux uses the scroll lock led on my laptop as a language switch indicator, when the secondary language is being used it lights up
It also makes my wifi led blink depending on how much bandwidth is being used
Windows never did either of those, all it did is its 50 minute updates and take 2 minutes to boot ON AN SSD while antix took 7 seconds
how does a distro like antiX which is supposed to be barebones have this out of the box?

My decade+ year old gaming PC's second lease on life

According to anaconda-ks.cfg I set my system up Mid July 2025. It's done the majority of what I need.
Every time I need something new I spend a little time looking for the best way to go about things.
I expect this to be a long process as new needs pop up. I keep some google docs on useful commands and the setups, configs, installs I've done so I don't need to reinvent the wheel if I ever crash or start fresh.
Free yourselves. Use old hardware. Avoid being tracked.
