I've added colour to the minibuffer propmt in the excellent visual-regexp.el! https://github.com/benma/visual-regexp.el/pull/32

Scheme rather encourages you to write an interpreter. JS is the total opposite: the engineering effort is intimidating.
Amusingly, no docs are available yet for the ARMv8.2-A arch, but we can see its new features through LLVM patches! https://llvmweekly.org/issue/100
The GCC wiki has a scary list of all the arithmetic transformations that don't work in compliant floating point C: https://gcc.gnu.org/wiki/FloatingPointMath#Transformations
When programming python, I miss the ability to advise functions. Decorators are like around-advice, but often after-advice is sufficient.
If you ever force push with git, you should really use --force-with-lease to avoid accidental clobbering. If you use magit, it's automatic!

Emacs package of the day: emacs-rustfmt: https://github.com/fbergroth/emacs-rustfmt . Automatically formatting code on save is a revelation.

Having an interpreter and compiler allows interesting workflows. E.g elisp users can try in the interpreter then compile when they're happy.
Emacs command of the day: kmacro-name-last-macro. Concocted a great macro? Save your last macro as a named command for later use.
Achievement unlocked: created a segfault using only safe @rustlang code! https://github.com/rust-lang/rust/issues/30081
The problem with lots of small commits is they're less helpful for the reader. I try to squash rather than producing a 'twitter feed'.
