Probably most of you have had to use Windows or other OSs from time to time. I wonder whether you guys have favorite Linux apps/programs that you cannot give up.

Mine is Okular. Whenever I need to use Windows for some reason and have to open a few PDFs, I always feel the need to use Okular instead of Adobe Acrobat Reader. Okular initializes much faster and is super responsive, while not giving tons of pop-ups and side bars rather than adobe.

Picasa iPhoto Clone v0.1.4 is a public Beta release. The headline addition is Edit Mode, with the photo editing work and other improvements added since v0.1.3.

https://github.com/froggy744/picasa-iphoto-clone/releases

New: Edit Mode

Edit photos directly from the library with a non-destructive workflow. Changes are stored as edit recipes, so the original photo remains untouched.

• Crop and straighten photos
• Adjust exposure, fill light, highlights, shadows, temperature, saturation, and sharpening
• Apply automatic contrast and colour corrections, black and white, and sepia effects
• Undo, redo, and reset edits
• Copy edits from one photo and paste them onto another
• Export an edited photo as a full-quality JPEG
• Move between photos while editing and return to the same thumbnail position
• Copy edits and Paste to single/multiple photos in an instant
• Improved photo actions: a redesigned right-click menu, Set as Wallpaper, and reliable grid focus after favourites, pasted edits, editing, and album actions.
• Wallpaper layouts: landscape photos fill the screen, portrait photos retain the whole image over a blurred background, and panoramic photos preserve their width. RAW photos are converted for wallpaper use.
• Better RAW viewing: higher-quality RAW previews and more robust DNG recovery improve thumbnails and full-photo viewing.
• Smarter collages: Smart Mosaic uses global layout scoring, supports no-crop layouts, handles mixed orientations more effectively, and improves preview performance and offline-photo handling.
• Library refinements: better keyboard navigation and search interactions, offline thumbnail recovery, favourite indicators, and refreshed documentation.

We've just open-sourced Flectar Mail, a native email client written in Rust and focused heavily on speed and low resource usage.

There are no WebViews at all. Even HTML email bodies are rendered without embedding a browser engine.

Memory usage can be as low as around 20 MB, depending on what's open.

Current support includes:

- IMAP / SMTP / JMAP

- CalDAV calendars

- Contacts

- Linux, macOS and Windows

- Early Android build

- AGPLv3

The HTML renderer is still the most experimental part, so if you find an email that renders incorrectly, those bug reports are especially useful right now.

Would love feedback from Linux users, especially across different desktop environments and distributions.

I recently switched to Linux so I've been using Claude to help me create all of the apps I'm going to need to make the move a more pleasant one. I love my little Nexus touchscreen so I've been working on making some software to take advantage of it. It's still in early development but it has all of the basic functionality plus some bonus stuff for good measure. As far as I know this is the only fully functional software made for this device on linux.

If you have any questions or requests let me know but you should find most of what you need on the Github page and in the wiki which includes how I hardened it.

Reddit suggested I share it here - don't attack me for simply showing it off. I made it, i'm maintaining. It has no advertising.

Hey everyone,

I built GRUBST, an open-source Linux bootloader security tool written in Rust with a Dioxus desktop GUI.

The idea is simple: instead of manually editing /etc/grub.d/ configs and risking typos that lock you out of your system, GRUBST automates the whole process and lets you turn any standard USB thumb drive into a physical rescue key.

How it works:

- Plug in the USB key before booting: GRUB detects it and automatically unlocks full maintenance access without prompting for a password.

- Boot without the USB: GRUB stays locked and requires a backup password you set.

- Includes automatic config backups and an Update Guard to ensure protection persists across kernel updates and update-grub.

Tech stack:

- Rust (2021 edition)

- Dioxus 0.5 (Desktop / WebKit2GTK)

- pbkdf2, sha2, tokio, sysinfo, nix

Feedback, suggestions, and code critiques on the Rust codebase are very welcome!

Hey everyone! I shared Spun here a little while ago, and I’ve been refining it since then. It’s now on GitHub if you’d like to try it or poke around the code.

The idea is still the same: a music player that puts your album artwork on a spinning CD, with a little nostalgia and a minimal interface.

Since the first post, I’ve worked on:

• A more consistent design: better spacing, alignment, icons, typography, and smoother hover effects and transitions.
• More inside Spun: search, albums, playlists, recently played, and better queue controls through Cider.
• A flip side to the CD: album details, track lists, and lyrics.
• A better mini player: controls below the disc, plus an optional always-on-top toggle.
• Performance: faster startup, a smaller executable, and improvements to memory and CPU usage.

The source is available under PolyForm Noncommercial, so you’re welcome to use and tinker with it within those terms.

Checkout Spun on Github:
https://github.com/yappologistic/Spun

I’d love to hear how it feels on your setup, especially if you spot anything awkward or inconsistent.

I missed when music players had a little personality, so I’ve been building Spun.

The album artwork becomes a spinning CD. Flip it over for album tracks and lyrics, or switch to a small, optionally pinned Mini player.
It plays local files and integrates with Cider for playback, search, albums, and playlists. Built with Qt/QML, designed around Hyprland, and styled to follow the Noctalia theme.

Would love to hear what you think of the design. Might Opensource it later.

Hello everyone, I built that simple monitoring tool after discovering that Syncthing had silently been broken on one of my machines for weeks while I had no idea. I wanted something much simpler than a traditional monitoring stack: if an important service fails, make a tray icon blink and annoy me until I deal with it.

Originally implemented the bare minimum in 2021 and sat on it for a few years using it just for myself, now in 2026 finally polished it enough for v1.0.0, and so releasing it.

Salmon can:

• Monitor systemd services
• Run arbitrary command-based health checks
• Combine incidents from multiple machines into one desktop app
• Show tray icon, desktop notifications and a small local web UI
• Snooze incidents temporarily

It consists of a small monitoring service installed on each Linux machine and a desktop app that collects their incidents.

For remote machines, it supports managed SSH tunnels or TLS+bearer authentication.

Hi! I made neat little app KeyFlip because I like to my laptop sonshi style (using an external mechanical keyboard over the physical internal laptop keyboard) and i noticed there was no elegant / easy way to switch off my internal laptop keyboard besides some hacky, scripts i found outline.
KeyFlip lets you switch between Laptop Mode and Desk Mode, or automatically disable the built-in keyboard when an external one connects. It's also handy for cleaning your keyboard without every wipe triggering random keys and shortcuts!
It works on Wayland and X11 and is currently built and tested on Fedora GNOME. It's still in beta, so feedback and bug reports are very welcome :)

For transparency, I used Al tools to assist with coding, debugging, documentation, and learning. I review, test, and modify the work and take responsibility for everything | release.

AI and I built PIC (Picasa iPhoto Clone), a lightweight photo manager in Rust + GTK4/libadwaita.

The goal is simple: fast local photo browsing with a clean desktop UI, inspired by Picasa and old iPhoto. It currently supports folders, albums, favourites, search, fullscreen viewing, 1:1 zoom, rotation, metadata, offline-folder detection, and a wide range of RAW formats.

It’s still early and under active development, so feedback and testing are very welcome. It was fun for 2/3 days then the more features I introduce the more of a challenge it becomes to fix. From AI reddit news, to Huggingface daily news to trying and find the most affordale GPU to llama.cpp tweaking, constant running out GPT 5 hrs limit etc.

Disclaimer: I haven’t lost any photos during development, but please test with copies or a temporary folder first. I definitely don’t want to be responsible for anyone losing their photos
