Today I learnt that dmesg has a -T argument, which makes it output human friendly timestamps. Another of the 'if only I'd known it earlier'.

Blogged: Adding a new language to Emacs: http://t.co/QRvLbZmqzs
Found some outdated elisp on stackoverflow and fixed it, but saw it had been copy-pasted on assorted repos. Code has a half-life sometimes.
Between functions, macros and blocks, I really enjoy lisps in the CL tradition (CL, elisp, others?). If I want to express something, I can.
Interesting JVM JIT example where the author rewrites code to help the optimiser: http://t.co/9sNIe7d59l (ideally we'd have the reverse!)
Implementing indentation correctly, in any editor, is hard. Here's an Emacs maintainer's summary of the process: https://github.com/emacs-mirror/emacs/blob/51e7e463e93708a0e40688f91200e9e9869ec662/lisp/emacs-lisp/smie.el#L61
The Genius website has an interesting design reminiscent of traditional hypertext. E.g. http://t.co/6dM8XY8syw
The Rust community continues to impress. Rustdoc has gained the ability for users to do Hoogle-style search by type! https://github.com/rust-lang/rust/pull/23289
It would be really interesting to add FIX/TIDY/FEAT to commit messages. You could then look at which lines change for fixes vs features.
Looked at a online community today with discussions going back to before 2001. Not many sites last that long!
Vim has a cute feature that when you undo, it tells you how old the change was that you're undoing. Is there an Emacs equivalent?
Undeployed code is almost always a liability. Deploy early and often.
Emacs' hexl-mode is smart enough to ignore line breaks in the ASCII display. Impressive! http://t.co/cLvuQFTb4R
Emacs feature of the day: `M-x calc' supports a dizzying range of arithmetic with arbitrary precision, and keybindings like M-/ work too!
A healthy server setup is one where you can restart a box without fear. It often takes work to reach that point sadly.
What are the disadvantages of open source projects growing? Are there diseconomies of scale?
TinyCC is so fast at compiling that you *can boot Linux from source*. Extraordinary! http://t.co/DQ8ueLPR2b
Fascinating rust compiler deep-dive on the steps necessary to implement incremental compilation: https://github.com/rust-lang/rfcs/pull/594
Excellent example of using ghp-import to generate a gh-pages branch with your HTML docs: http://t.co/40un66gbMB
