would you really rather choose safe things like. restaurant. or. chocolate. or. idk. whatever

@marcsh @fermatslibrary yes all good mate

@usrbinishan @fermatslibrary F_ck, my bad. Damn Yes, you have to check if its _in_ the sphere, otherwise you get 8 bunched up parts of the sphere

The way to correctly generate a random point on the surface of a unit sphere is not to pick uniform distributions θ in [0,2π) and φ in [0,π), but instead choose u and v from uniform distributions on [0,1). Then φ = cos⁻¹(2v-1) θ = 2πu

@marcsh @fermatslibrary @marcsh did you mean to say if distance <= 1 normalize, and reject all others? that one is correctly uniform and is the standard way you'd apply rejection sampling.

@marcsh @fermatslibrary imagine a cube with a sphere in it. now consider one face of the cube and one of the corners. the center of the face will get projected onto 1 spot on the sphere. but every point on the ray from the center to the corner that is outside the sphere goes to 1 spot on the sphere.

@hackclub @NASA fire

Next week, we are hosting an online AMA (ask-me-anything) session with Jared Isaacman, the head of @NASA! If you are a teenager, sign up on hack.club/isaacman and get a chance to ask him a question!

@adic_inf 😵‍💫

@pronounced_kyle @tkexpress11 currently around 10%

@tkexpress11 Astranis was like 30-40% interns at various times

thoughts on hiring interns?

@cis_female a story

who i texted over the last three years

@augmentaltech cool

MouthPad is a touchpad you drive with your tongue. Now available across the US.

@NASASpaceflight huh

T-0 Abort. SpaceX Falcon 9 B1082-23 scrubs the launch of Starlink Group 17-39 from SLC-4E, Vandenberg.

@exsponged why no run

I am going insane not being able to run

It’s been 95 degrees all week

@IsaacKing314 earlier one

My partner asked me to pick her up from the airport at "midnight on Monday". I requested clarification, but received none. The airport is an hour away. The deadline approaches.

@__alpoge__ 😵‍💫

hello there the jacobian conjecture is false thanx to my close friend akhil for asking about it and my other close friend fable for working during the world cup final ((1+xy)^3 z + y^2 (1+xy) (4+3xy), y + 3 x (1+xy)^2 z + 3 x y^2 (4+3xy), 2 x - 3 x^2 y - x^3 z): \C^3\to \C^3, has jacobian determinant -2, and sends (0, 0, -1/4), (1, -3/2, 13/2), and (-1, 3/2, 13/2) to (-1/4, 0, 0)

@astro_Pettit wow

Scanning electron microscope look at the hopper crystals I grew on ISS. These are potassium chloride crystals exhibiting a relatively rare "scroll" morphology with step-like structures under weightless conditions.

@DonaldPMitchell _what_

The craziest thing about this fabrication is the two transistors are made on separate wafers and then positioned and stacked to atomic precision. It seems impossible.

IBM transistor. Conductors 15 atoms thick.

@SapphoSys wtf lol

TIL macOS supports up to 30 notification actions

@Lubchansky woah

DID YOU KNOW IF YOU FIND A HORSESHOE CRAB THATS BEEN TAGGED BY THE FISH AND WILDLIFE SERVICE AND SUBMIT THE LOCATION YOU SAW IT USING THE FORM ON FWS DOT GOV SLASH CRABTAG THEY SEND YOU A BEAUTIFUL CRAB PIN

@grandsurvival_ dumpling story. alcatraz

things to do in sf? will be visiting for a few days

@Appyg99 aw :/

It’s funny how when your pet dies, you lose a part of your core habits. You don’t care about the vet anymore, you never see your cat-sitter again and you stop buying extra litter or food at a random grocery run. The worst part is you lose your polite excuse to avoid staying out late. No cat to feed!
