I forget where I found this, so if anyone wants to claim attribution, let me know and I'll add a line here. If put into /etc/profile.d/serial-console.sh, the following will auto size a serial terminal windows size and create a function for manually adjusting later. Since I access RPIs and BBBs via the serial console, their tty names are already listed in the case statement; add others if your system is different. rsz helps when you later reconnect and minicom or screen is in a different sized window...

    rsz() {
        if [[ -t 0 && $# -eq 0 ]];then
                local IFS='[;' escape geometry x y
                echo -ne '\e7\e[r\e[999;999H\e[6n\e8'
                read -sd R escape geometry
                x=${geometry##*;} y=${geometry%%;*}
                if [[ ${COLUMNS} -eq ${x} && ${LINES} -eq ${y} ]];then

echo "${TERM} ${x}x${y}"

Installation of NixOS with encrypted root

These are my notes on instaling NixOS 16.03 on a Lenovo ThinkPad X1 Carbon (4th generation) with an encrypted root file system using UEFI.

Most of this is scrambled from the following pages:

• Encrypted Root on NixOS - Nix Wiki
• Installing NixOS - Chris Martin
• Linux administration and use - Earl Douglas
• Installing NixOS on a ThinkPad W540 with encrypted root - Bluish Coder

Adaptive Streaming has become the neccessity for streaming video and audio. Unfortantely, as of this post, there isn't a whole lot of tutorials that accumulate all of the steps to get this working. Hopefully this post achieves that. This post focuses on using Amazon Web Services (AWS) to transcode for HLS and DASH and be the Content Delivery Network (CDN) that delivers the stream to your web page. We'll be using Video.js for the HTML5 player as well as javascript support libaries to make Video.js work with HLS and DASH.

So Here's what you need:

• An AWS Account
• Video.js
• videojs-contrib-hls.min.js
• dash.all.min.js
• videojs-dash.min.js

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore (except for perhaps a few exceptional occasions). ]

---

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.
