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?

what's a simple command or noscript that felt like a magic trick once you learned it?

We all have that moment where you discover a command or a one-liner that saves you from a ton of manual work and you wonder how you ever lived without it.

For me, it was learning about 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 cd - to jump back to the previous directory.

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 winecfg, on the Applications tab select Add Application, and browse trough users/yoursillyusername/AppData/Local/SumatraPDF select the SumatraPDF.exe file and open it.
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 Show in Folder, it opens with wine default and basic explorer.exe, i could not switch to Dolphin. So any help is welcome here.


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.

"Learn to code" to use Linux.

On the internet I often see people say they would like to try or use Linux, due to recent Microsoft shenanigans with AI, but they don't know "how to code" and that they would need to "learn to code" (whatever that means). Why is that? And what can be done to change the image of Linux for the average person?

I just contributed to Linux World FIRST TIMEEEEE HELLL JAAAAAA!~

There was some issue in Linux Mint Cinnamon, where if you have animations enabled inside your App menu they would cause some big stutter. And it was Mint-Y theme issue only.

Here is the video - https://streamable.com/8x8gld
At the start of the video you can see what I'm talking about, and then near the center I reloaded Cinnamon with the fix and I think you can clearly see the difference!

So I found a way how to fix it and just requested a pull to fix it here - https://github.com/linuxmint/mint-themes/pull/523 even thought it doesn't pulled to the main branch for now, I still enjoy it :3

wayscriber v0.8 – live screen annotation & screenshot overlay for Linux (KDE Wayland, GNOME, Hyprland…)


hey, i've been hacking for a while with Rust on a little zoomit-style overlay for linux, and i just pushed wayscriber v0.8 🙂 finally ready to share with folks outside Hyprland

https://github.com/devmobasa/wayscriber

GIF preview: https://wayscriber.com/demo.gif

It started as a very simple real-time annotation tool with only freehand and arrow/rectangle shape..

welp, several weeks fast forward, and I added bunch more features, and ended up with quite a codebase... all more than I planned for, mostly other people requesting ( but... I swear... all the features made sense!)


### what it does (in short)

- draw over anything: pen, straight lines, rectangles, ellipses, arrows, multiline text, choose colors etc.
- use it as a whiteboard/blackboard or transparent overlay on top of your actual apps
- quickly hide / redact parts of the screen (nice for demos, support, recording)
- built‑in screenshot helpers (region, active window, fullscreen) to file or clipboard
- freeze screen mode so viewers see a paused frame while apps keep running
- runs either as a one-shot (wayscriber --active) or a small background daemon you toggle with a hotkey


it’s basically a live drawing / annotation layer for your screen. you hit a hotkey, screen fades, and you can scribble, highlight stuff, freeze screen, undo everything and redo everything, hide bits of the screen and grab quick screenshots.


---

### v0.8 focus: KDE Wayland + beyond

until v0.7 it was very hyprland‑focused, v0.8 tries to play nicer with the bigger players:

- KDE Plasma / KWin (Wayland) – uses layer‑shell, so the overlay actually sits on top like it should, and all works great
- GNOME – works via the xdg fallback; you can draw over windows and desktop, but can’t paint over the top bar (portal / compositor limits, not me crying about 47 failed tries to fix it… ok maybe a bit)
- still works on wlroots compositors like Hyprland, Sway, Wayfire, River, Niri etc.

real hardware i’ve tested on so far:

- Ubuntu 25.10 GNOME and KDE
- Fedora 43 KDE and GNOME
- Debian 13.2 KDE and GNOME
- Arch with Hyprland
- Niri was tested as well

if you get it running somewhere else, would love to hear.

---

### install (desktop stuff only, for now)

### Debian / Ubuntu (.deb):

wget -O wayscriber-amd64.deb \
  https://github.com/devmobasa/wayscriber/releases/latest/download/wayscriber-amd64.deb

sudo apt install ./wayscriber-amd64.deb

### Fedora/RHEL (.rpm)

wget -O wayscriber-x86_64.rpm \
  https://github.com/devmobasa/wayscriber/releases/latest/download/wayscriber-x86_64.rpm

sudo rpm -Uvh wayscriber-x86_64.rpm

### Arch (AUR):
yay -S wayscriber

or prebuilt
yay -S wayscriber-bin

on other distros you can build from source (needs a recent version of rust), and for best screenshot workflow you probably want wl-clipboard, grim and slurp installed.

### what i’d love feedback on

- KDE Wayland: does the overlay behave nicely on multi‑monitor / mixed‑DPI setups?
- GNOME: any weirdness besides the top bar no‑draw area? (that’s kinda expected sadly)
- other compositors i didn’t list above
- any horrible performance / latency issues on low end hardware



bug reports & feature requests very welcome, even small stuff like "this hotkey combo makes no sense"

Ram Upgrade

Hello everyone,

CachyOS x GNOME user here. I own a Ryzen 5 3500U with Vega 8 graphics laptop. Currently it's got 16GB of ram on it 2GBs of it is allocated for VRAM. I am mostly doing multitasking with lots of tabs and workspaces on and I am thinking of upgrading it to 40GB. Is it worth it?
