02/10/2021 (things i learned)

• fell asleep reading indonesia rupiah wikiepdia lol

• omg algebra is for a bunch of NERDS... "In group theory, a Dedekind group is a group G such that every subgroup of G is normal. All abelian groups are Dedekind groups. A non-abelian Dedekind group is called a Hamiltonian group."

• oh, actually nvm that was quite understandable, except now i see why the hate for the term "normal".. oh it's not so bad actually..: In other words, a subgroup N {\displaystyle N} N of the group G {\displaystyle G} G is normal in G {\displaystyle G} G if and only if g n g − 1 ∈ N {\displaystyle gng^{-1}\in N} {\displaystyle gng^{-1}\in N} for all g ∈ G {\displaystyle g\in G} g\in G and n ∈ N . {\displaystyle n\in N.} {\displaystyle n\in N.}

• holy shitttt, if only people made lean exercises for basic things in a pedagogical manner... like i learned so much about quotients when kbuzz wrote the substraction definition of integers. I'd probably have so much fun learning algebra then

• huh i feel sad getting ghosted by the lean puzzle game maker now :( the one based off the colonizer book, godel escher bach GEB

• holy shit the technical coolness of these whatsapp groups are amazing, they crash whatsapp, have a 7 day long video that's <20kB, lag the phone like crazy

• huh google still really sucks at filtering, probably no safe search by default. ecosia filters graphic images quite well, not perfect tho, but they're terrible at filtering links, where google is much
