  • 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.

    Erythritol may impair cellular functions essential to maintaining brain blood vessel health, according to researchers at the University of Colorado Boulder. Findings suggest that erythritol increases oxidative stress, disrupts nitric oxide signaling, raises vasoconstrictive peptide production, and d...

  • 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).

  • 𝗠𝗲𝗴𝗮𝘁𝗵𝗿𝗲𝗮𝗱 needs to be updated
  • 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.

  • Oh, I know. But imagine, if you will, if enough people collectively decided to vote 3rd party. It's a minority of Americans who even vote at all. If a third party received the majority of votes, they would have to be put in office -- hypothetically at least.

    This is a proposal for how we could potentially bypass the two-party system and set up a government that actually represents the will of the people.

    Six new beetle species have been discovered in South America by researchers at the University of Copenhagen. Among them is one with a distinctively shaped sexual organ that has led the researchers to name it after global beer powerhouse Carlsberg. According to the researchers, more attention urgentl...

    Six newly discovered beetle species include one with bottle-opener shaped genitalia

    Researchers often use the genitalia of insects to differentiate species, since they are a reliable signature of a species uniqueness. A newly discovered beetle has been found to have genitalia that look remarkably similar to a bottle opener.
