FWIW, the editor they use, at least on the web, seems to be https://github.com/quilljs/quill . I'm guessing Slack implemented something a-la https://github.com/patleeman/quill-markdown-shortcut

You don't really need much math for SICP. You can learn a few random pieces of math from SICP, and without background that will be harder and you might feel like you're missing out, but these are just examples; you can just tru

My recommendations are not exactly what you ask but what I suspect you'll enjoy if you're asking this. (1) "Understanding Computation" by Tom Stuart. Not "fundamental" as a deep textbook, but very approachable

Same here about volume 1 — I only have it because my father got it somewhere but neither of us read it much, it's just collecting dust. However I'm now buying & progressing through volume 4 which Knuth is gradually releasing,

That would be Rakuv רקוב, just Raku doesn't have any meaning in Hebrew. It does sound similar when pronounced though. (Hebrew word formation is from 3-consonant roots, not concatenation, so removing a letter doesn't give a relat

Similar tip: don't start a command from `rm -rf ...`, type `rm /foo/bar/` first only when finished append ` -rf` at the end. Similarly `git push ... -f` etc.

`keep-header` is a superb gem of do-one-thing composability.

Comments are great for human-edited config files, but not a clear win for an stdout/in format. The trouble is, comments are normally defined as having no effect, not part of the data model. But iff the comments contain useful informati

No experience with them in python, but look also for PEG grammars. They are significantly simpler than the traditional tower of lexer + ambiguous limited lookahead grammar. Plus the memoized Packrat algorithm allows throwing in functions w

However, one side reflective/white one absorbing black is possible. I guess the weight of extra paint is not attractive, compared to attitude control which you need anyway. EDIT: this matters because full 180° reflection is like &quo

Very nice! Reminds me of Markdeep diagrams [1]. The examples are almost identical, so I'm curious if one of them should give credit to the other? Or was there a shared ancestor? Either way, the core insight that it's OK to map

I think "Name it and they will come" is now a pretty good quotable name for the Naming / storytelling Solution.

eqn (part of troff) from 1974, predating TeX, had a very decent syntax! It's not as complete as TeX, and the layout quality is worse, and I wouldn't want to touch the rest of troff syntax. So not really practical, but good inspir

Indeed. But (not sure if that's what GP meant just guessing) it's sad that tons of middleboxes that peeked too much inside packets effectively broke "end-to-end" goals, so now it's impractical to deploy any new pro

TAOUP had a chapter "a tale of 5 editors" discussing emacs, vi, and more, and does point out emacs is an outlier (and outsider) to many unix principles. It does quote Doug McIlroy speaking against it (but also against vi?). It at

In the hashing department: - Zobrist hashing. It's completely incredible that such a trivial scheme is a near-perfect hash for sets. That's before you even consider the useful ability to compute hashes of related sets with added

rsync was indeed a dramatic "this should not be possible" feat. But the way it uses rolling hashes is not the simplest possible. One side sends hashes of fixed-size chunks, the other scans input for rolling hash matches, which on

Yep; it's one-dimentional variant of Error Diffusion (which itself is a notably beautiful dithering algorithm), where "input" = slope of line and output is quantized dy=0 or dy=1. Dithering also appears in audio. The old PC

I had the same gut reaction when I heard the PEP even exists. But now I actually read the PEP, it's very well written and makes a reasonably good case that in specific scenarios it will be an improvement. (My second gut reaction was

Alt+. is a bash (libreadline really) key. In fish Alt+Up does something similar, but repeated presses iterates over all words of all commands rather than last words of bash commands. A big improvement is you can type some chars first and t

History file may be read & updated simultaneously my multiple processes. Is that sufficiently safe from corruption with SQLite? (honest question, no FUD implied. same risks apply to alternatives too.)
