Because modern web is bloatware. Too much javascript, CSS, ads and cookie popups. A phone's hardware and internet speeds are generally not as fast as a desktop. So, it takes much longer to render on a phone.

Also, a lot websites nowadays deliberately make their mobile web experience shitty (cough ** reddit cough) to force their users to install their app.

Zram is basically a compressed swap device located in your ram. You can check the usage by running zramctl.

I would recommend setting mem_limit to 10 GB or disk_size to 40GB and algorithm to lz4.

Zram usually has a very high compression ratio - around 4:1 for lz4 and 6:1 for zstd. You can set zram to 40-50 GB. It will still use less than 1/2 of your ram.

Zram has an option to write poorly compressible data to the disk instead of storing it in the ram. I would split the swap partition - 3 GB for zram writeback and rest for ordinary swap.

I was using flakes. I gave the reason why it's data intensive. If a core dependency like glibc is updated, it's hash will change and all packages that depend on it need to be rebuilt and rehashed. It'll download all packages again even though there's minimal change.

Interesting! Any reason for this choice instead of doing everything through nix?

[–] 7ai 1 points 1 year ago

That's quite convincing :) I've been meaning to try gentoo for many years actually. I'll install it soon and report back!

Haha yeah. Flatpak is pretty much like having 2 linux systems on your machine at once. And of course it can be worse sometimes.

[–] 7ai 1 points 1 year ago (2 children)

Nix has a great potential as a replacement for flatpak actually as it is source based. You can guarantee what you are installing is based on which source code by compiling yourself.

Flatpak and the others are packaged by upstream. A developer can put malware in a package and upload it to flathub. That's why it needs permission management, sandboxing etc to minimize the risk.

Yep. I used the Xfce iso.

Thank you that makes sense. When I get my hands on a more powerful machine and have less data constraints, I'll try Nixos again. I do miss it sometimes 😆

A laptop with 8 GB of ram and 6 cores. I have only one machine that I use for work. That's the main issueI. Need to find a free weekend to compile and try out gentoo 😅

 

I hopped from arch (2010-2019) to Nixos (2019-2023). I had my issues with it but being a functional programmer, I really liked the declarative style of configuring your OS. That was until last week. I decided to try out void Linux (musl). I'm happy with it so far.

Why did I switch?

  1. Nix is extremely slow and data intensive (compared to xbps). I mean sometimes 100-1000x or more. I know it is not a fair comparison because nix is doing much more. Even for small tweaks or dependency / toolchain update it'll download/rebuild all packages. This would mean 3-10GB (or more) download on Nixos for something that is a few KB or MB on xbps.

  2. Everything is noticeably slower. My system used way more CPU and Ram even during idle. CPU was at 1-3% during idle and my battery life was 2 to 3.5h. Xfce idle ram usage was 1.5 GB on Nixos. On Void it's around 0.5GB. I easily get 5-7h of battery life for my normal usage. It is 10h-12h if I am reading an ebook.

Nix disables a lot of compiler optimisations apparently for reproducibility. Maybe this is the reason?

  1. Just a lot of random bugs. Firefox would sometimes leak memory and hang. I have only 8 GB of ram. WiFi reconnecting all the time randomly. No such issues so far with void.

  2. Of course the abstractions and the language have a learning curve. It's harder for a beginner to package or do something which is not already exposed as an option. (This wasn't a big issue for me most of the time.)

For now, I'll enjoy the speed and simplicity of void. It has less packages compared to nix but I have flatpak if needed. So far, I had to install only Android studio with it.

My verdict is to use Nixos for servers and shared dev environments. For desktop it's probably not suitable for most.
