TIL in sh, you can press C-w to delete previous word and C-u to delete the whole line.

I stole this technique from Lawrence Block's outstanding Telling Lies for Fun and Profit, a book about writing fiction. He suggests drafting a story the "natural" way, with the first chapter introducing the hero and the second getting the action going, then swapping the two chapters.

Brilliant!

Various tricks to mess with webpages - actually quite useful! For example, have you thought of modifying the state of the program using a conditional breakpoint?

Bash tip: put cleanup code in a function called finish and register it with trap finish EXIT.

I agree. Every screenshot I took is a snapshot of memory of what I was currently doing on my computer.

A tool to quickly find the CRF setting needed for achieving target VMAF score.

A great way of managing system level dotfiles. TL;DR:

alias dotfiles='git --git-dir=/home/mx/.dotfiles --work-tree=/'
dotfiles config --local status.showUntrackedFiles no

Then managing the files would be simple basic git operations. No symlinking, installation, synchronization, etc.

Alternatively, it's also sensible to set the worktree to $HOME.

A lot of Linux command line tips and tricks.

A lot of useful emacs debugging tools (built-in). With those I saved a lot of time to troubleshoot and fix various problems.

In addition, don't forget that there are edebug and trace-function which can also come in handy.

This trick has greatly increased the browser usability on my phone.

Emacs has a lot of little known built-in features that can cover a lot of use cases provided by packages. This article presented some of them. Really nice to learn about them.

Also read the sequel, "More batteries included with emacs" (https://karthinks.com/software/more-batteries-included-with-emacs/).

A bunch of quite useful tricks. Some I already used and other's are new. Here are the headings:

1. Forward Yubikey Agent
2. Reuse connections
3. SSH straight into tmux
4. Alias commonly used hosts
5. Do not add testing stuff to ~/.ssh/known_hosts
6. Make connections last longer
7. Canonicalize hostnames
8. Yubikey and GitHub, without touching it every time

I find it quite helpful to create a persistent connection to github. It greatly reduces my connection latency for pushing and pulling.

You could harden a Linux server by killing the init process. That would cause a kernel panic, and prevent new processes running (e.g. shells). Existing processes like Web servers would continue to function, so you could put this at the end of the boot script :)

I never thought that is possible! Kind of stupidily funny and brilliant at the same time.

A bunch of nice tricks to use browsers' web debugger console and console.log() faimilies.
