every time I Google "-ize vs -ise", "-or vs -our", etc., I am like "I should make an Anki deck with some basic rules" — time passes, and then I am punctually reminded of that fantastic idea when I Google "-ize vs -ise", "-or vs -our", etc. again — Ad infinitum

you're born a bee, how to you learn to do that coordinated attack? (it's a question I wonder about animals in general, how does an ant learn to be an ant?)https://twitter.com/TheBrandonMorse/status/1257668293370040321 …

that is handy specially if you create new applications often — I do to check stuff, investigate Rails issues, etc.

another executable decoration, this one wraps the `rails` command — after `rails new` you're right in the application folder and with an editor launched rails() { if command rails "$@"; then [[ $1 == "new" ]] && cd "$2" && code -n . fi }

Sincerely, let’s be honest, when the Black Gate of Mordor starts to open, how many in the army are thinking “THE FUCK I’m doing here”

And there are more, they are constructed, their arithmetic defined, the properties demonstrated, etc. It is in this context that you have to watch the video, Conway discovered (as he puts it) the surreal numbers, which have infinite and infinitessimals at all levels you can think

Reals have two traditional constructions: Dedekind cuts, and equivalence classes of Cauchy sequences (I saw this one in full detail in my 1st year) — Cantor defined the ordinal numbers in Set Theory, which are the naturals and a huge amount of different, ordered infinities

In modern math, numbers are not taken for granted, the naturals are defined in Set Theory as 0 = ∅, 1 = {∅}, 2 = {∅, {∅}}, and so on — Integers are defined by an equivalence relation on ℕ × ℕ — Rationals by an equivalence relation on ℤ × ℤ \ {0}

wonder about the spontaneous inner thoughts of Physicists in a Yoga class or spiritual setting in which they are told about “energies”

shell functions take precendence over executables, so the command you copy from the website () gets effectively decorated — also, a shell function is able to change the CWD, you can't do that in a script because it runs in a different process

I've copied the destination directory of @exercism_io exercises more times than I'll admit, enough! exercism() { local bin="/usr/local/bin/exercism" if [[ $1 == "download" ]]; then cd "$("$bin" "$@" 2>&1 | tail -n1)" else "$bin" "$@" fi }
