Linux on Reddit

Hey everyone, I recently got selected for the Linux Foundation LiFT Scholarship, and honestly, I wasn't expecting it at all. My background is mostly full-stack web development. I've been contributing to open source for a while, which is probably the main reason I got selected. The funny part is that when I applied, I didn't have a clear plan, I just thought, "why not?" and now I've actually been accepted. The problem is that I don't really know how to make the most of this opportunity. My current stack is centered around web development, and while I enjoy building products, I've been getting increasingly curious about infrastructure, cloud, containers, deployment, automation, and the whole DevOps/cloud-native side of things. I don't have much hands-on experience there yet. I'm trying to figure out: Which Linux Foundation courses provide the highest ROI? Should I focus on Linux fundamentals first (LFCS path)? Is Kubernetes worth learning at this stage, or is it overhyped for someone coming from full-stack? Would you recommend a DevOps/cloud-native path, or should I double down on backend/system design instead? If you've received the LiFT Scholarship before, what courses did you take and how did they impact your career? My goal isn't to collect certifications. I'd rather use the scholarship to learn skills that will genuinely make me a better engineer and help me contribute more effectively to open source projects. I'd especially love to hear from people who started as web developers and later moved into DevOps, platform engineering, cloud engineering, or SRE roles. Thanks! 🙏 submitted by /u/Content-Medium-7956 [link] [comments]

If like me you've had issues with migrating to wayland because it doesn't let you alter gamma values on the fly, hopefully this script I made will help. It will generate simple ICC profiles you can use to correct the gamma, using the same syntax as xrandr does. Disclaimer: This was written with Claude AI. It's a simple one shot script, so calm down, it does the job. https://github.com/BaconCatBug/Make-Gamma-ICC submitted by /u/BaconCatBug [link] [comments]

Hey there! This sub has become quite difficult to follow - every few hours, there's the next post for "I built a TUI for X", which translates to "I vibecoded an ncurses interface for a bash two-liner". Unfortunately, this also means that the important content gets lost in a stream of meaningless posts. What I'd like to ask for: - a rule for mandatory AI disclosure - an entry barrier for software packages; a task easily solved in <20 lines of shell code should not qualify as a distinct contribution Let me know what you think. submitted by /u/First_Result_1166 [link] [comments]

It took me around a week to install Linux From Scratch 4.1, and I finally did it! I used Debian 3.0 as the host OS (obviously on VirtualBox, I don't have access to any old PCs from the 2000s to run it on) to resolve any possible problems when compiling 20+ year old packages (which were really hard to get, I had to use the Wayback Machine and Debian/Slackware archives to get the correct packages... Before I discovered a dedicated internet archive page with all the required packages) I'm absolutely happy with the result. At least the system boots up without crashing submitted by /u/Lolscope_from_2020 [link] [comments]

Disclaimer: as a developer, I'm not very happy about how LLMs are changing the way we develop things, but I also believe it's one of the best things happened to Linux, probably on the long run, and here is why. I made a post years ago about me trying to switch to Linux fully, I tried multiple times and it was very hard for me to ditch windows due to the software I use for my work and for gaming, but Linux Desktop kept getting better and better over those years. A year ago, I burned the ships and switched fully to Fedora with no dual booting either, and I have never been happier with my PC, since then I was able to replace all the software I use for something that works on Linux. Except one thing that was merely cosmetic, but annoyed me very much because I love it, and it was really expensive xD, my Kraken elite 360 CPU cooler. While NZXT CAM is a horrible software TBH, but it was the only way to manage the screen on this hardware, I have tried this library: https://github.com/liquidctl/liquidctl it works, but it basically just uploads a GIF to the pump screen, I needed to show temps or pc stats, as well, CAM software used to basically render any web page with stats overlay, and I wanted that. ------------------------------------------------------------------------------------------------------------ So I used Claude to develop a quick software to manage the screen load gifs and other features using a simple GUI, the problem is, based on the github library, I wasn't able to achieve crisp steaming from the PC, it used double buckets to upload images then swap, which gave me 5 fps at best, and the github library litterly listed my device as "broken" so I decided to reverse engineer how CAM does it, sadly, it doesn't run on Linux, I used Winboat to install CAM on Linux, and gave the USB to my docker and it detected the kraken pump, but it needed GPU to render, which I couldn't do with docker (no GPU passthrough) I almost gave up at this point, because it was too much work to install windows just to capture how CAM streams the video, then I found a library that has USB over IP, I had another machine with windows installed at home, I installed NZXT on it and forwarded the USB of my kraken over the network to the windows machine, and the pump appeared in CAM ! Next I captured the traffic going through the USB IP on my PC using wire shark and I had a full dump for how cam streams videos to the pump I gave the dump to Claude code and it reversed the sequence of calls done and added it to the software, next thing I know, I have a full crisp stream of a full headless chrome page streamed to the pump screen Now I have a full software, with custom dashboard (any html would work really), GIF loops, uploading videos, running web pages, anything really! ------------------------------------------------------------------------------------------------------------ that's why I mentioned in the beginning that LLMs are a really great push for Linux, I think a lot of devs can now close the gaps of needed software that wasn't feasible on Linux or not worth it, this crazy ride I had would have taken me a month to complete at least, and I finished in 1~2 days, and I think some one who knows what he is doing (I have never dealt with drivers before) would have finished faster Running our website inside the pump screen by URL only: https://imgur.com/kjR3Kdr here is the github for the program I made: https://github.com/KhalloufHassan/kraken-elite-screen-manager submitted by /u/khallouf_hassan [link] [comments]

Comparison of epoll and io_uring in Linux. Explanation of my opinion why io_uring should be used in new projects with asynchronous I/O. It's giving a huge performance boost in comparison to epoll. I'll be happy to discuss any questions about the security and compatibility of io_uring, tell your opinion about that topics. :) submitted by /u/Sibexico [link] [comments]

This month I found physical CDs of Red Flag Linux 2.0 and 3.0 on Chinese marketplaces (lost media cds, I posted about them earlier and I think many people already saw it). This time I went further and want to properly write everything about them ​ Some notes on both versions: Version 3.0 feels more like a server build than a desktop, most applications don't work, there's only 1 game (which corrupts the UI when launched) and Paint is broken Version 2.0 is extremely difficult to install and boot, it took me around 1.5-2 hours to get it running and fix all errors. Without a tutorial it's going to be very painful. That's also why I didn't bother porting it to Apple TV. Its the more complete system by far, all games work (Snake, Billiards, PacMan, Tetris and more), there's a file manager, text editor, support for any screen resolution, and basically everything you'd expect from a desktop (everything that 3.0 is missing) ​ I may dig deeper into both systems in the future, but one thing I can already confirm that both versions idle at around 40 MB of RAM ​ The discs I have differ slightly from the ones preserved on archive.org, mine are a bit newer builds. But that felt like a boring answer so I ported version 3.0 to apple tv gen 1 ​ This method should now work for almost any early Linux distro built on kernel ~2.4.7 running on Apple TV hardware (e.g. old builds of Red Hat 32-bit) This took me around 10-15 hours ​ What was required: Hybrid MBR to bridge the gap between GPT (Apple TV) and MBR-only Linux 2.4.7 Direct kernel hex patching at binary offset 0x1FC to fix hardcoded root partition paths x86 assembly utilities to force IRQ 10 assignment for the ICH7M USB controller, since 2001-2002 drivers had no knowledge of its existence (I don't know assembly so Claude Sonnet was my copilot here) ​ Because the utilities are already baked into the image you can swap in your own ISO, patch IRQ = 10 and older Linux distros should boot fine. Both original ISOs (~1 GB each) + the Apple TV image (~5 GB) and an automated bash installer script are available for download on my preservation page: https://errordanofficial.github.io/redflaglinux/ ​ The website exists ONLY for preservation purposes, the ISOs and install tutorials are there because without them getting any of this running is nearly impossible submitted by /u/Error_Dan [link] [comments]

Tauon is a cross-platform desktop music player, primarily made for Linux. Now I know what you're thinking, yet another vibe coded slop music player to add to the pile. Hear me out, its actually been in development for over 10 years. We have a small but dedicated user base. You probably just never heard of it because I suck at marketing. Since I last made a post on Reddit we've added support for milkdrop visualisations (very cool), Jellyfin support, more UI customisation and improved theming support. If you're in the market for a new music player then check it out!
