GRUB broken? I wrote a noscript to quickly reinstall it (UEFI + BTRFS/EXT4 support)

Hey folks 👋

I often ran into messy GRUB reinstall situations on UEFI systems with BTRFS or EXT4. Since reinstalling GRUB manually every time was tedious, I made a simple Bash noscript that automates the process.



🔹 Works with UEFI boot

🔹 Handles BTRFS and EXT4 layouts

🔹 Cross-distro friendly (tested on Debian, Ubuntu, Arch)

What's happening with Nix OS? Why introduce unrelated politics in Software Maintainance?

https://www.youtube.com/watch?v=rFouWH7J6fs

I have seen this video about Nix OS project Maintainers banning people based on their personal political biases. This kind of behaviour is not good for an open source software.

Doesn't matter what your personal political or religious believes are, I really don't think we need to let that affect our open source projects. These projects are for everyone, you shouldn't discriminate based on your personal biasis.

What do you guys think of this?

Applying Android’s Zygote model to backend service deployment

Hi, this post may not be directly related to Linux, but I think many people here are active in backend and cloud engineering. I originally shared this idea on r/Backend but didn’t get much insight, so I’m posting it here to get broader feedback.

The thing is while digging into Android internals, I came across Zygote. In Android, Zygote initializes the ART runtime and preloads common frameworks/libraries. When an app is launched, Zygote forks, applies isolation (namespaces, cgroups, seccomp, SELinux), and the child process starts almost instantly since it inherits the initialized runtime and class structures.

Why not apply a similar approach to backend infrastructure.

Imagine a cluster node where a parent process initializes the JVM via JNI_CreateJavaVM and preloads commonly used frameworks/libraries (e.g., JDK classes, Spring Boot, gRPC, Kafka client).
This parent never calls main()—it’s sterile, holding only the initialized runtime and class metadata (klass structures, method tables, constant pools, vtables).So the Parent heap is mainly polluted by the parased class metadata and structures of these frameworks and libraries.
When a service/pod needs to start, the parent forks. The child inherits the initialized runtime state, class metadata, and pre-parsed framework bytecode. It only needs to load its own business logic .jar and configs, then set up networking (sockets, DB connections, etc.). No repeated parsing or verification of framework classes. Cold-start latency drops, since only service-specific code is loaded at runtime.

Fork semantics make this efficient:

1.Shared runtime .text +frameworks/libraries bytecodes+parsed class metadata of these stay read-only and shared across children.

2.Copy-on-write applies when say the child's JIT modifies class structures of these shared framework libraries such as method tables or other mutable structures.

3.Each child can then be mounted onto different namespace and also other Linux primitives such as cgroups, seccomp can be applied to provide container like isolation.

->The parent per node acts as a warm pool of pre-initialized JVM state.

For large-scale self owned systems (Uber, Meta) you could even do multi-level forking. For example, a top-level parent initializes runtime + common libraries/framework's Then, multiple sub-parents forked from top-level preload service-specific frameworks and bussiness logic (e.g., Uber’s ride-matching or fare calculation). Scaling would then fork directly from the sub-parent, giving instances both the global runtime state and the service-specific state spining up almost instantly.

Chromium HDR is Awesome

So recently in the AUR I saw they released a Chromium version which supports HDR. Installed and mind was blown away. The HDR is so good and so freaking bright on my 600 nits OLED laptop. Eyeballs melting lol. I was also pleased to see that it also supports HDR photos, AVIF HDR looks nice. I just wish there was JPEG-XL support 😐

Can't believe we're in this timeline where you can watch YouTube HDR videos on Linux. Even Firefox supports YouTube HDR lol (Not photos yet as Chrome does though). What a good time to be alive! I wish there was Widevine L1 support to really tie everything together, but alas, we can't have all the good things haha.

To anyone who wants to try this:
1) Install google-chrome-dev 141.0.7367 from AUR, this is the version which has HDR support.
2) Install KDE 6.4.4+, which is the version that supports HDR. Might need to enable unstable repo in Pacman (and maybe switch back to stable after the installation to keep things.. well.. stable)
3) In chrome://flags, enable Vulkan, enable Default ANGLE Vulkan, enable Vulkan from ANGLE, set Force Color Profile to HDR10

That's it, YouTube HDR should now be working. My favorite YouTube HDR test videos:
1) https://www.youtube.com/watch?v=jci_nhleoXA (this will scorch your retinas, in a good way of course)
2) https://www.youtube.com/watch?v=CQT1qcAax2A (looks nice too)

To test HDR photos use these:

Gnome + Wayland is making linux more user friendly.

And thats why the main distros do ship this combination. I finally do get it. You install Debian, Ubuntu or Fedora and everything just perfectly works. Minimal tweaking but you have perfect fractional scaling, perfect external monitor support with different scaling, apps and theme looks beautiful, hdr support and apps are consistent. People that oppose this way and goes against, i dont really know what to say...

Kudos to all developers for making linux literally an alternative for day to day computing.

Is there any university that use Linux with libreoffice or onlyoffice instead of Windows and Microsoft Office?

I know there are many governmental organisations that are switching from Windows and MS Office to Linux and Libreoffice following concerns about telemetry in Windows and Microsoft software. But I wonder if there is any university you know that use Linux and libreoffice by default instead of Microsoft office?

Bitnami just killed off their free Docker images and I'm scrambling

I've been using Bitnami images for years in my homelab setup, mostly for stuff like PostgreSQL and Redis because they were straightforward and kept up with security patches without much hassle. Now Broadcom decides to pull the plug on the free tier and shove everything behind a paywall? It's frustrating as hell, especially since a lot of my deployments rely on these pulls not failing out of nowhere. I've got a couple of weeks to fix this before things start breaking. Anyone got solid alternatives for these? I'm looking at official images but worried about the CVE counts spiking. What's everyone switching to?

Ubuntu Studio for music production?

I found an old laptop that I wanna transform into a portable workstation for creative works. I found Ubuntu Studio as a lighter weight OS geared towards creativity, and with my minimal Linux experience, is it worthwhile? Does anyone have experience using it with music software like audio workstations? Do I have to do a lot of tricky stuff to get it to work? And how does compatibility fare? Thanks.

Over 10 years of using Linux, and I think I'm done

Not in the way of "I'm done with Linux", oh no no. It's just...



I think in the life of every Linux person (or maybe it appeals to other hobbies/passions) there comes a time, when you're just simply DONE. Done reinstalling the system every couple of weeks. Done finding the best, newest trend there is. Done spending hours and hours troubleshooting and fixing issues with your extremely customized setup. Done scouring the forums and Reddit looking for answers on why this absolute newest, bleeding edge RC kernel is causing you problems. Just DONE.

I've been distrohopping since I can remember. I had a brief year of using Arch (but not really, I was hopping between all Arch-based distros), then about a year or two using Fedora, but still trying out everything new that was coming out. I was in awe with all the new and shiny.

But now I'm in my 30s. I don't have time, nor headspace to wonder if my system will boot today, if the update won't break anything, if this new kernel won't cause me some weird, unexplainable issues. My OS has to boot and get out of my way. It's my terminal to the work, not my work.

So here I am. Writing this on Waterfox (basically Firefox ESR) from Linux Mint 22.1 with LTS kernel, installed on absolutely ridiculously powerful gaming machine. Do I care if I don't get new bells and whistles that come with newer kernels, newer DE versions, newer Firefox releases? No. I absolutely do not. I value the fact, that in about a year of having this Mint installation, I have NEVER had to reinstall it or fix anything. It just works. I feel no incentive to change anything here. I even use the default theming.

So, what's your story? Am I the only one, who came up to this mindset? Or maybe there are more of us? I leave the comments to you.

Switching to Linux - A comprehensive guide

I’ve been seeing a lot of people wanting to switch to GNU/Linux(shortly just Linux) recently, owing to various reasons including Windows 10 EOL, forced integration of AI tools, screenshot spying, bloatware, etc. and I thought I’d make a comprehensive guide based on my experience.

Please feel free to correct me when I’m mistaken and add inputs/suggestions.
Hope it helps.

Been using Linux for 20 years, this is my story.

I pick a mainstream distro that “just works”, then I forget about it and just use my computer.

I might revisit my decision in 4 or 5 years if my system needs a wiping or the OS reached EoL and/or has trouble updating to the latest version… or maybe not.

The end.
