I've put quite a bit of work into my i3 set up recently and I'm curious if the people here are interested in that kind of thing.

I'd be interested in looking through configs to get ideas, and sharing screenshots and such.

Here is what my desktop looks like right now. Let me know what you think.

I still mainly use Windows, although I've dual-booted Linux a few times and I have Linux Mint on an old laptop right now. One thing I've never understood about Linux is all the different distributions - their different reputations and why they have them. What is the mechanical difference between using one distribution of Linux and another? Or are the differences usually not mechanical?

For example, Ubuntu and Debian seem to be large families, meaning that a lot of other distributions are based on them (using packages built for them in their package managers at least) as well as being popular distros on their own. But what's different between the two of them, and between each and the other distros based on them? (and what's similar? I gather they all use the Linux kernel at least!)

I also know that people are quite opinionated on their choice of distro, I wondered what reasons people had for their choice. What things are easier or harder for you in your distro of choice? Is it mainly day-to-day tasks that are important or more how the OS works underneath? How much difference does your preferred distro make?

For myself, I've only used Kubuntu (though not much) and Linux Mint, which was mainly for UI reasons, and particularly for the latter, ease of use for someone used to Windows (at least that was what I found years ago when I first looked into it).

Though I doubt I'll ever fully move away from Windows I would like / need to have access to a Linux OS, so maybe this will help me to know what is important to look for. But I also hope it'll be a useful and interesting discussion topic. Also, there are some previous discussions on the latter question so I'd be more interested in learning about the main topic.

also, please do add more tags

I've got a crappy Chromebook running GalliumOS (Xubuntu) and Chromium is slow as molasses. I tried a few other browsers like Otter and Falkon. They're alright for most sites -- not Tildes, but this seems consistent with QT5 browsers.

Anyway, outside of text browsers, anybody have any light weight browser suggestions?

My Linux desktop is having a bit of difficulty with bad sectors. Lately I've had to boot into recovery and run an fsck a few times to try to fix a problem where the OS drops into read-only mode at the drop of a hat. Today I tried copying some files from one directory to another and got the following error message:
cp: error reading "foo/bar": Input/output error

I've just booted into a live USB and run fsck /dev/sda1 -c and it fixed a load of bad sectors, but the above error message is still happening.

A bit of googling tells me that this is down to bad sectors on the SSD, and I'm not really sure what that means. Is anybody able to enlighten me? And as a follow-up question, would reformatting the hard drive resolve the problem, or are there any other things I can try to fix it?

Since I took so long to reply to Tips to use NixOS on a server? by @simao, I decided to create a new topic to share my configs. Hopefully this is informative for anyone looking to do similar things - I'll also gladly take critiques, since my setup is probably not perfect.

First, I will share the output of 'lsblk' on my VPS:

NAME      MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
vda       253:0    0   180G  0 disk  
├─vda1    253:1    0   512M  0 part  /boot
└─vda2    253:2    0 179.5G  0 part  
  └─crypt 254:0    0 179.5G  0 crypt 

That is, I use an unencrypted /boot partition, vda1, with GRUB 2 to prompt for a passphrase during boot, to unlock the LUKS encrypted vda2. I prefer to use ZFS as my file system for the encrypted drive, and LUKS rather than ZFS encryption. This is an MBR drive, since that's what my VPS provider uses, though UEFI would look the same. The particular way I do this also requires access through the provider's tools, and not ssh or similar. The hardware-configuration.nix file reflects this:

# Do not modify this file!  It was generated by ‘nixos-generate-config’
# and may be overwritten by future invocations.  Please make changes
# to /etc/nixos/configuration.nix instead.

Edit: Also, the provider I use is ExtraVM, who has been excellent.

I see some people using NixOs on their servers. I would like to try it out to self host some services and learn about NixOs.

I use hetzner and they have an NixOs iso available so I can just use that to install NixOs. But how do people manage remote instances of NixOs? They would just use ansible or something like it, to run nix on the host, or is there a better way?

Thanks

Sorry if this is a silly question, but I keep running into situations where a small CLI or GUI tool that could be handed a single file and hand me back an encrypted version would be useful. I've done some googling, but all I typically turn up is blogspam about random Windows-only tools that seem to be of dubious quality.

Anyone know of a good tool for this type of thing?

I'm trying to package Elmer for use with NixOS, and could use some help from any experienced Nix users. My current attempt is located here. There is some junk left around in that file from my experimenting, but it's at least a start. There are also a few lines of error included in the comment here.

Any help is appreciated!

I don't wanna get into a heated discussion, so let me make something very clear: for a regular user, video editing on Linux is probably fine.

That is just not my use case.

I'm used to a degree of freedom, choice, and stability that, right now, Linux does not provide in that area.

I'm a film major who has worked as a professional video editor for many years and editing video on anything that is not nearly as good, reliable and precise as Adobe Premiere feels like torture.

But even being very flexible regarding features and requirements, after trying all the regular suggestions, as professional tools, and with all the respect I can muster, they are just unusable for me.

I need a reliable program in which I can throw any format without worrying about constant crashes, but Linux options are all either extremely limited, unstable or both! Before anyone asks: I tried multiple programs, in different versions and installation methods, on entirely different hardware and unaffiliated distributions.

Kdenlive resembles professional-grade software but constantly crashes at the simplest operations. DaVinci Resolve seems like a good bet but is a nightmare just to install and equally crashy when/if I'm able to do so (last time I had to manually edit the install script following the instructions of some random forum post. This did not cause a good impression. And audio didn't work), and I'm not willing to use something so finicky if Linux doesn't get primary support.

Besides, Blackmagic Design only provides a few pieces of the puzzle. Professional video editing requires a whole stack of integrated software. Both Windows and Mac OS have this, Linux has not.

There's also the issue of GPU acceleration.

I'm not saying FOSS developers owe me anything, nor that they have done a bad job with programs like OpenShot, Pitivi, Blender, whatever. I'm just saying that, regrettably, I'll probably have to install put Windows on dual-boot on my machine in the next few days.

Hey everyone, just watching a very interesting history of Terry A Davis (creator of TempleOS) and around the 30 minute mark there is a list of questions Terry asked to God and the answers he believed he received. I took a look online but was unable to find anything. I don't suppose anyone out there has a link? I'd be very interested to read it. Thanks in advance.

EDIT: I'm also interested in any links to the art he created (hymns, visual art etc).

I'm interested in C or Go, but i'm open to ideas.

I have plenty of sh scripts i created to integrate my tools and system, so i have some experience and i don't want a scripting language like python.

My first plan is to learn the basics of the language and rewrite some of those scripts.

I think my first pick will be a script that uses ffmpeg to convert my flac files to mp3 or opus. I use sndconv -opus/-mp3 and it checks if there are flac files in the folder (i only have full albums), converts and puts in a folder named "$artist - $album".

My long term goal is to make a cli/tui music player like cmus.

UPDATE: i'm having plenty of success with Go right now. I just wrote a basic version of my music conversion script. It's just converting a music i pass as argument to mp3, but i'll keep working on it and adding functionality just to dip my toes in Go. It seems like a good language and i'm having fun!

Thanks for all the answers!

EDIT: SOLVED

It looks like it was much simple than I thought and someone solved it on Reddit already. I won't delete, just leave the link if someone is interested.

Runtime Environment

Issue

Sometimes I use "whereis" (aliased for "wh", but it doesn't make any difference...) for my own scripts.

I usually copy their paths manually (using tmux) and paste to the command line resulting in something like this:

nvim /home/my_username/my_scripts_folder/my_script

Could I make that into a single command?

Thanks in advance!

I know there are similar products I could buy in the US that would give me this experience, but I'm not in the US and I don't have much money.

In the old days, my father had some kind of machine that was not a proper laptop and not a proper typewriter. It opened instantly to a text editor. As far as I remember, there was no noticeable boot time. It had a keyboard and an entry for a floppy disk. You typed your stuff, saved it to the floppy disk, probably to send via email or to print in another machine. I loved that machine.

I love these little gadgets that do one thing and one thing only. And, as someone with severe ADHD, they're often a necessity. If my Kindle had Youtube I would never read a book. If my PS4 had Emacs I would never play a game. The list goes on, but the principle is this: a lot of things are useful to me precisely because of what they cannot do.

And that is why I wanna recreate my father's crazy computer-typewriter.

Because I know how to use the command line, it really needs to be in total lockdown: I open it up, it shows a very simple text editor (with a few handy features that make it works even more like a typewriter) that I cannot configure, tinker or alter in any way. It's focused on writing (not editing) literature because that's what I need and other kinds of writing require an internet connection.

It would save and back up automatically (like a typewriter) to one or more drives at your choice.

There would need to be a few options because of different screen sizes, the number of screens etc, with an interface to make it easier.

So the idea is an ultra-minimal, kiosk-mode Linux distribution that can either go on a flash drive or be installed on an old laptop. No package management, no internet connection, no access to the command line, no configuration files, no distractions whatsoever. I wanna forget I'm even using Linux. I wanna recreate my father's typewriter/computer that he never let me touch.

How do I do this?

I currently use MX-Linux, which is a great distribution but does require me to reinstall it from time to time. It also comes with all the good/bad Debian legacy, and sometimes things can get really fucked up (okay, I admit it: MX IS NOT PERFECT. But nothing is, okay? Settle down.)

My new Linux Distribution doesn't need to have all the new bells and whistles, but it needs to be able to stay reasonably current with new packages and innovations. I don't mind some manual work, but I also don't wanna spend my days maintaining the system.

This distro is supposed to be a tool to work with, not a hobby to be pimped, riced or whatever. I will occasionally play and edit videos on it (don't worry, it's all AMD, thank you advice for the Tildes ;)

I use the i3wm window manager (not the gaps fork), so native support is a must and current versions are preferable (MX's version is from 2016. 2016!). If there's not a current version of Emacs, I'll compile my own. The same is true for Neovim, dmenu, rofi and the suckless terminal.

Configurations on text files do not scare me, but I don't wanna spend all my time scripting stuff. I don't mind compiling stuff either so Gentoo and other source-based distributions are valid options (as long as they allow me to work on stuff instead of working on the distribution...). That said, I have no preference whatsoever between binary and source-based.

Unstable distributions like Arch and even Manjaro are a no-no. I need my computer to work 99.99% of the time, like a fucking refrigerator. That said, I would like some newer packages and tools such as Gimp, Inkscape and a video editor like Kdenlive. Maybe flatpak is an option? I was never able to get it to work properly.

I'm also open to crazy things like Nix, but only if it'll make my life easier: I have no philosophies on the mater.

Any suggestions?
