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.

Disclaimer: Please follow this guide being aware of the fact that I'm not an expert regarding the things outlined below, however I made my best attempt. A few people in IRC confirmed it worked for them and the results looked acceptable.

Attention: After following all the steps run gdk-pixbuf-query-loaders --update-cache as root, this prevents various gdk-related bugs that have been reported in the last few hours. Symptoms are varied, and for Cinnamon the DE fails to start entirely while for XFCE the icon theme seemingly can't be changed anymore etc.

Check the gist's comments for any further tips and instructions, especially if you are running into problems!

# Converts a mysqldump file into a Sqlite 3 compatible file. It also extracts the MySQL `KEY xxxxx` from the
# CREATE block and create them in separate commands _after_ all the INSERTs.

# Awk is choosen because it's fast and portable. You can use gawk, original awk or even the lightning fast mawk.
# The mysqldump file is traversed only once.

# Usage: $ ./mysql2sqlite mysqldump-opts db-name | sqlite3 database.sqlite
# Example: $ ./mysql2sqlite --no-data -u root -pMySecretPassWord myDbase | sqlite3 database.sqlite

STC Micro 8051 Microcontroller Notes

Quick Notes

The critical few things you need to know about it are:

1. They are 1T (single clock cycle) 8051 compatible MCUs (but some instructions may take as many as 5 or 6 clock cycles to complete) and most are capable of operating at up to 35MHz. Check the markings on your part. If it says something like "28I", then it means that your part has been rated to operate at up to 28MHz. Note that rather than use nice round numbers like 12MHz, which is possible, it is more customary to use specific operating frequencies that facilitate the generation of a lower error UART baud rate. I.e., 11.0592MHz, than would otherwise be possible.
2. They have a built-in bootloader that emits a magic number, then listens on UART0 (RxD, TxD) on bootup. The ISP programmer uses this.
3. There are two main HEX file download tools, the manufacturer's own STCISP which is an all singing and dancing development support tool (it has pinout information, timer configuration and code generation t
