Linux From Scratch - great way to learn about linux

Hello,

I am using Linux for 16 years or so. Part of my job has to do with Linux servers.
But I always wanted to finish a LFS-10-systemd and today I did it. Covid and snow gave me the time :-)
My first try was 14 years or so ago and I didn't finish it. But even then, it had teached me a lot.

What is Linux From Scratch? It is a book, not a distro. It describes step by step, how to build a Linux system. If you follow this book and everything goes right, you will have a running Linux in the end.

To my mind, it is a good way to get a feeling for Linux, you get your hands on every package, that is more or less necessary. It can be a bit boring, but if you are completely new to Linux you can learn so much about the core elements. If you get really hooked, you can dive deeper with BLFS, Beyond Linux From Scratch.
If you are not new, it can still teaches you a lot. Most of us use a distro, use some commands and we are good. LFS can give you a new perspective on Linux.
LFS will not become my daily driver, I will stuck to Debian, but I will revisit it from time to time.

To me LFS is a good way for the curious.

Error proofing for shell noscripts: shellproof

shellcheck is an util that checks shell programs for common mistakes.

So I got this simple idea: what if we combined the debugging of shellcheck with that of running the code itself, so everything is checked quickly together?

I called it shellproof. It does a quite simple thing: it runs a shell program only if it is mistake free, otherwise it lists those mistakes.

So debugging a program just takes:

shellproof [programPath\]

Best lightweight Linux distro for a newb.

I've just about had enough of Windows 10's constant forced updates, and this has driven me to consider Linux for the first time. I have two low-spec laptops that currently run Win10 that I'd like to switch to Linux if I can. I'm aware there are any different varieties of Linux out there to pick from, but I'd prefer to run a lightweight version that can run on a potato system.

Any advice and tips appreciated.

Distro recommendations for an all time Windows user?

Been using Windows forever and now I want to see how the Linux side of things are, plus to avoid all that MS-Telemetry thing that's going on with Win10. Recently tried Elementary OS Hera and got my laptop's touchpad working after a bit of tinkering in the BIOS but found out there aren't many gestures. Any distro where I can get a similar feel of the touchpad gestures? Heard that Elementary OS 6 is gonna come out with better 1:1 gesture support but until that arrives, what are my options?

Windows is behaving like over-possessive partner in Dual boot

I am using Linux and Windows both in dual boot. I don’t know why, my windows gets a problem with its BCD every once in a month and I need to reinstall this irritating operating system again only because I need to use Adobe Softwares occasionally. Anyone else facing the same issue? I badly need to get rid of this BCD corruption frequently. My machine is an Asus X570 ZD with Windows pre-installed.

Alternatives to dialog with more control on colors and more modern looking?

Working on a project where we need to improve ux of an installer. We are using dialog right now but would love to better match company colors and make it look a bit more modern.

Can anyone suggest an alternative?

How to properly use databases in my application from a superuser account?

What is the best method to incorporate databases in my application? I am using a superuser account to run the application. While I can run the application from this, I don't want to give it superuser privileges to all the databases in the system. What's the standard? Am I supposed to create a new standard user while setting it up and assign a database to it?

Media center

I'm trying to redo my media center. It once was a window 7 machine, for almost 10 years. However it is my last machine to be transferred to Linux. For one reason my sound card it has a brand new one. A sound blaster, any idea what distro will accept it without drama, I have had very little luck.

Is it normal to have a bin folder in your home directory?

Here comes a weird question. I've been using Linux for more than 8 years and I always create a bin dir in home. That's where I keep all my executable files, DRM free software etc. I don't remember why am I doing this, is this normal?

Linux on a Samsung Galaxy Book 10.6

Hi all!
I have a Samsung Galaxy Book 10.6 ... tried Ubuntu 20.04 on the machine and didn't had wifi, the touch wasn't working and the keyboard was buggy (when I detached and attached again stopped working).

Should I try another distro? o what should I do?

​

PS: I'm a noob on Linux. I was trying to use WSL2 for windows .... but I prefer to have a real Linux machine.

Some nifty stuff ffmpeg can do

# play a video
ffplay output.mp4

# play audio only
ffplay -nodisp output.mp4

# audio streaming of a youtube video
youtube-dl https://www.youtube.com/watch?v=dQw4w9WgXcQ -f bestaudio -o - | ffplay - -nodisp

WAYLAND USERS, LOOK AWAY!

# record screen and save as video
ffmpeg -f x11grab -i :0.0 -f pulse -i 0 output.mp4

# record part of the screen as gif for 5 with seconds
# with 800x600 resolution, 0 x-offset and 30 the y-offset
ffmpeg -f x11grab -framerate 10 -video_size 800x600 -i :0.0+0,30 -t 5 output.gif

# take a screenshot and save as png
ffmpeg -f x11grab -i :0 -t 1 -f mjpeg output.png

Note: the last three commands obviously requires X11, and ffplay may require installing ffmpeg-full on some distros (which is only 2 MiB if ffmpeg is already installed, at least on NixOs)

To be honest, I'm still reading ffmpeg's man page and I don't understand these commands much myself, I just shamelessly copied them from various websites. It all started this morning when I wanted to record the screen using peek (gif screen recorder) which didn't work due to some missing GTK dependency, did some Google-fu and now I'm uninstalling peek in addition to mpv, scrot and kazam (which IMO only serve as wrappers for ffmpeg) ... I can say that things escalated quickly.
