    Driver support will always potentially be an issue unless you buy laptops that are built for Linux, or are well vetted. This is because Microsoft has near total market control and Linux support is usually reverse engineered later if the drivers source is never shared.

    Same thing for gaming – gaming support on Linux is mostly a bunch of ad hock hacks, because those games were never made to run on Linux in the first place.

    So, if you want to commit to Linux, make it an informed choice. You will need to make some sacrifices. Or you could always just dip your toes and only use Linux for running a server or hosting a website.








  • here we go:

    dedup:

    #!/usr/bin/awk -f
    !x[$0]++
    

    this removes duplicate lines, preserving line order

    iter:

    #!/usr/bin/bash
    if [[ "${@}" =~ /$ ]]; then
        xargs -rd '\n' -I {} "${@}"{}
    else
        xargs -rd '\n' -I {} "${@}" {}
    fi
    

    This executes a command for each line. It can also be used to compare two directories, ie:

    du -sh * > sizes; ls | iter du -sh ../kittens/ > sizes2
    

    fadeout:

    #!/bin/bash
    # I use this to fade out layered brown noise that I play at a volume of 130%
    # This takes about 2 minutes to run, and the volume is at zero several seconds before it's done.
    # ################
    # DBUS_SESSION_BUS_ADDRESS is needed so that playerctl can find the dbus to use MPRIS so it can control mpv
    export DBUS_SESSION_BUS_ADDRESS="unix:path=/run/user/1000/bus"
    # ################
    for i in {130..0}
    do
        volume=$(echo "scale=3;$i/100" | bc)
        sleep 2.3
        playerctl --player=mpv volume $volume
    done
    

    lbn:

    #!/bin/bash
    #lbn_pid=$(cat ~/.local/state/lbn.pid)
    if pgrep -fl layered_brown
    then
    	pkill -f layered_brown
    else
    	export DBUS_SESSION_BUS_ADDRESS="unix:path=/run/user/1000/bus"
    	mpv -ao pulse ~/layered_brown_noise.mp3 >>lbn.log 2>&1 &
    	sleep 3
    	playerctl -p mpv volume 1.3 >>lbn.log 2>&1 &
    fi
    

    This plays “layered brown noise” by crysknife. It’s a great sleep aid.

    here are some aliases:

    alias m='mpc random off; mpc clear'
    alias mpcc='ncmpcpp'
    alias thesaurus='dict -d moby-thesaurus'
    alias wtf='dict -d vera'
    alias tvplayer='mpv -fs --geometry=768x1366+1366+0'
    

  • Not exactly sure, but playing with setting up your own VPN will give you an idea of it.

    Essentially, the VPN is run on a remote server. When you connect to the VPN, your traffic gets masqueraded out through the remote server, and replies get natted back to you. If you tried setting up a webserver on your computer and then accessing the webserver on the VPN server IP, it wouldn’t work, because the request coming in to the VPN server port would by default just reach the VPN server at that port.

    This is where port forwarding comes in – if the VPN server allows you to port forward, you can set port X on the VPN server to go to port Y on your router (which would likely also have to port forward on your router to get to your computer).




  • Port forwarding allows you to seed without revealing your IP address. If you seed on a VPN and you don’t have port forwarding, your IP is revealed to those you seed to.

    Edit – I was wrong. You can technically seed securely behind a VPN connection, but since you can’t be connected to directly behind a vpn without port forwarding, you would only be able to seed to ppl who port forward, or who can be connected to directly. You would only be able to leech from everyone else.

    If everyone torrented like this (behind a VPN without port forwarding), all torrents would grind to a halt; nobody would be able to seed.
