I made some visualizations to better understand and explain isogeny-based , the SIDH protocol and its claw-attack 😄

No zombies, no purges, no half naked cannibal people in funny cars with skulls and bones... What a shitty apocalypse!

"What was the first concert you attended? What was the name of your first love? What is your favourite holiday destination?"

The Canadian Revenue Agency's new "security" questions are indistinguishable from dating questions. Do they want my taxes or my love?

overall impressions of using windows for the first time in... well, let's just say a long time:

sure you can boot up a game in it, but the game will crash at critical points. everything is really locked down, and in order to do anything remotely hackerish you will end up with a folder of weird EXEs that you feel nervous running because you can't view the source, and they're from weird places on the internet with a lot of ads.

there are adverts everywhere in the operating system's display, and... it feels kind of... 'cheap' - like microsoft doesn't care about windows. it just looks and sounds cheap.

by contrast linux, BSD, and free desktop environments look really glossy, or matte, and seem really responsive

OH! yes, on the topic of responsive: windows will just lock up for no reason sometimes. and there's nothing you can do about it.

i think the one things i like best about windows is the metallic grinding noise you get when it crashes and diplays a BSOD

i will routinely yell YAY IT'S BROKEN when that happens.

overall score: annoying/10

#2281 "Coronavirus Research" 

"Also, reading 500 coronavirus papers in a row and not sleeping? Probably not great for you either, but I haven't found any studies confirming that yet. I'll keep looking."

Someone in (the IRC channel) just taught me that zip also unzips:

If

xy = zip(x, y)

then

x, y = zip(*xy)

(It breaks if xy is empty, so just check for that beforehand)

Very curious that the effective response to a global crisis is to stop all the shitty parts of capitalism as quickly as possible. Suspend rents, interest, loans, provide people with healthcare, and the ability to get food. The host body is in trouble and the parasite ceases

Challenge for applied category theory: build a ronavirus, so that the world can be sane again.

#2274 "Stargazing 3" 

If we can destroy enough of the lights in our region, we may see more comets, but that's a risk we'll have to take.

I mean, theoretically, this algorithm is the best one as of today to find graph isomorphisms. However, in practice, nobody uses it because there is no implementation anywhere and world+dog use VFS2.

Do you happen to know, by any ultra-rare chance, any implementation of this algorithm? "Graph Isomorphism in Quasipolynomial Time" arxiv.org/abs/1512.03547

I don't know why I have this obsession of trying to work on a problem until I intimately understand it.

I do this with math too. I don't really have to know the proofs of every result I use, but I can't help trying to at least wanting to know why something is true, even if it's just in broad strokes. I won't stop until I get it.

This ends up wasting a lot of time as I absorb details that aren't really important.
