Repost a meme that lets us get to know you better:

A meme featuring a conversation between two Wojack figures labeled “normal people with a Time Machine.” One figure says to the other, “Hello. I’m your granddaughter.” The other replies, “Really? Incredible!” Lower on the meme, a bearded Wojack in a black hoody addresses two mammoths and a mastodon. Their conversation is labeled “me with a Time Machine.” The bearded figure says, “More apes like me will try to migrate north via the isthmus of Suez. You cannot defend against their spears in the daylight. But they are vulnerable while they sleep. Come night, follow the glow of fire and smell of smoke.” The elephants respond, “grateful proboscidean noises.”

stackoverflow.com/questions/22... this includes a rundown of the glibc algorithm that seems to do really well generally, it seems like maybe this has more or less been settled over the last couple years?

How does C compute sin() and other math functions?

I've been poring through .NET disassemblies and the GCC source code, but can't seem to find anywhere the actual implementation of sin() and other math functions... they always seem to be referencing

something I am learning about you is that you are a long video watcher of considerable taste. this is I think the fourth roughly hour long video I've seen you link to and they all seem super interesting

I feel like the issue we're converging to is "what if your number is too big to stick into physically plausible computers" at which point I have completely lost track of the question of efficiency

I took three CS courses. the third one was a systems course and that was what convinced me not to do a minor lol

it seems like the large input problem is really a problem that arises for almost any function with irrational period and has very little to go with sin. and then somehow even with small inputs there's purportedly no good algorithm for computing sin

is there some sort of remedial wonkism school we can send these people to? these are the most illiterate posts I've ever seen on this site. "public schools are basically the same as a childlessness tax" i stg

K. Chen @tznkai.bsky.social · 7h

Something I've found is that people respond to this idea very differently depending on if you put any effort into hiding you're doing this. Broadly speaking, childless people are fine paying taxes for public schools and not fine paying a childlessness tax even though they're basically the same thing

William B. Fuckley @opinionhaver.bsky.social · 8h

My most controversial take on this is probably that while I think reproductive freedom should be sacrosanct, I don’t really have any problem with additional taxes on (high income) childless people. Someone gotta pay into the pensions!

you ever feel like we're living in a golden age of grift? not just in the sense that grifters are more successful than ever but in the sense that the level of grifting talent is unprecedented. every week someone takes the game to a new level

i think we should sacrifice white women who live in new jersey and have 3 or more kids. the majority of the country is not going to die on the hill those people's rights. it’s long-horizon strategy

from now on I'm just going to truncate the taylor series for sin at the first term. sin(x) = 0 for all x. this approximation

- is efficient to compute
- has bounded error
- has excellent analytic properties
- has very high accuracy for small values, which occur frequently in applications

wait what

There is no standard algorithm for calculating sine and cosine. IEEE 754, the most widely used standard for the specification of reliable floating-point computation, does not address calculating trigonometric functions such as sine. The reason is that no efficient algorithm is known for computing sine and cosine with a specified accuracy, especially for large inputs.[53]

calibrating financial flows to reward or punish people for having children is a very popular concept in the far right. it's been discussed, and it fucking sucks! direct money to make children's lives better. that, not family structure engineering, is where you have a moral and societal imperative

"person becomes in favor of social control once they would no longer actually be subject to it" is a pretty well worn pattern

This South Side Weekly report on the Chicago building raid is well worth reading. Most striking to me are the indications of collusion between federal authorities and the building owner and management to effect a mass eviction at the blighted property. southsideweekly.com/federal-agen...
