@cwebber@octodon.social why? it looks pretty dead
I've been playing around with the Surreal numbers and one thing that prompted is how to get to non-dyadic rationals from dyadic rationals. You can approach them by bouncing back and forth between dyadic rationals like this for 1/17:
- 1/8 ≈ 0.125 (target=0.058823529411764705)
- 1/16 ≈ 0.0625 (target=0.058823529411764705)
- 1/32 ≈ 0.03125 (target=0.058823529411764705)
+ 3/64 ≈ 0.046875 (target=0.058823529411764705)
+ 7/128 ≈ 0.0546875 (target=0.058823529411764705)
+ 15/256 ≈ 0.05859375 (target=0.058823529411764705)
This makes some cool little patterns based on whether you are adjust up or down. 1/17 is boring, but 1/13 is a bit fun: 000100111011000100111011

I usually ignore these videos on ars because I hate that they automatically play videos on mobile (very rude), but this is pretty interesting. I'd like to actually play the Blade Runner game, and I hardly even play video games anymore.

New NFT things: https://babysongbirdsnft.com , (on blue bird @BabySongbirds ).
Don't buy them: it infringes my moral right (https://davidrevoy.com/article864/) and they added CC-By compliance just now after fans noticed.

#TIL Back in 2005, John Gilmore and Zooko (both are well-known cypherpunks) told Linus Torvalds he should avoid using SHA-1 in git right now before it's too late, since it was already theoretically unsound. Linus completely rejected this suggestion. 
He said the attack is theoretical, and git's hash is not meant for security anyway - if you want to use git securely, you should only trust your local tree and never pull code from a public server.
This decision basically summarizes the upstream kernel community's historical attitude on security mitigations...
RT @bascule@twitter.com: 2005 John Gilmore vs Linus Torvalds on SHA1 "debate" in a nutshell https://www.metzdowd.com/pipermail/cryptography/2017-February/031623.html
RT @zooko@twitter.com: I, too, begged Linus not to use SHA1 and he (indirectly) mocked me for it. IIRC I suggested that they use Tiger-192 instead. If they had, it would still be working fine and would not require an upgrade.
https://arstechnica.com/science/2021/11/with-tonights-launch-nasa-starts-getting-serious-about-planetary-defense/ I'm sorry but "planetary defense" is just cool. I shouted "Heck, yeah!" out loud to no one when I heard about this program
@freemo It doesn't look like the per-post expiration made it, but a per-user setting did get merged https://github.com/mastodon/mastodon/pull/16529.
I just noticed today that mstdn.social has it already.

@galaxis idc about that so much. more annoyed that my 6 word random passphrases aren't allowed
@izaya funny, I'm just the opposite 😆
mostly kidding about you though. I attribute most perceived standoffishness to the communication medium.
@izaya ah, that's good. i thought it was intentional.

re: I don't know what I've been told..
You can also evaporate something (but only as long as you have something to evaporate). Surprisingly many spacecraft used evaporative cooling at least sometimes (Gemini had an evaporator that seemed to have been used at low flow continuously, Apollo LM was cooled purely by evaporation, Apollo CSM had an evaporator to allow higher heat rejection rates than by radiators alone and as the sole way to dispose of heat after the SM was gone, Shuttle had an evaporator to cover high heat load intervals and, I assume, to help in the case the payload doors won't open).
@Virtualface@mastodon.social 😆 I remember there was a solid week in which I was *very* into this style of dance. I tried it, but was too uncoordinated to really pull it off. I don't think my hips and knees could take it these days.

Q: If system programmers create a music genre, what would it be?
A: Dumpedcore.
@izaya is that a flesh napkin or something? it's vaguely upsetting
