you can’t see the majority of starlinks with the naked eye, what you’re seeing is either some other constellation or freshly launches starlinks that are still orbit raising. once starlinks are at altitude they actively manage their reflecti

My ex coworkers at spacex are pretty damn motivated to get to mars, many of them despite all the Musking happening. I wouldn’t bet against them.

Yeah I’ve wanted to build this for ages (and have tried a couple times). The use case is festivals/sporting events and other places where permanent infrastructure doesn’t really exist. The hard part is keeping messages small if you wan

Wild. I was in my 4th/5th years of college during the pandemic and had an internship writing mission planning tooling for lucy. Felt like either two weeks or ten years, coding on the couch while we were pretty sure the world was ending

Don’t do this, it makes it a huge pain to test bar(). When you write the initial code to figure out bar, just throw that code in a unit test so you can run it any time. Stop throwing tests away!

The target market is the same as normal mining, you probably mine platinum. The cost probably only closes with either starship or mining fuel in space.

In what languages is n % 2 -1 for negative odd numbers? Edit: apparently JS, java, and C all do this. That’s horrifying

An algorithm is “a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer” How does a giant pile of linear algebra not meet that definition?

Musk owns 79% of voting shares of spacex (but yes, only 42% of equity). I guess it depends on your definition of “owns”, but its not unreasonable to say he owns spacex.

What? Carbonaceous chondrites (the toyota corolla of asteroids) are like .1ppm gold, whereas Earth’s crust is ~0.005ppm https://pubs.usgs.gov/circ/1968/0603/report.pdf

It wouldn’t surprise me at all if early heat seeking missiles used just a PID controller, since a big part of what makes PID attractive is the ability to implement it with electrical components. Take a pair of IR photodiodes and wire them s

The idea is that, because of the risk of a technological explosion, any sentient species is a threat. I don’t really buy the idea though - cooperation has been the strongest strength of humanity and is one of our greatest evolutionary edges

This is the biggest storm since 2003! We hit a G5 on the SWPC geomagnetic storm reading, and my team had to power down components on our satellites to keep them safe!

There isn’t really a “why”, other than the need to match observed reality. We know from observations that light moves at a constant speed, even when the observer is moving near the speed of light, and we know that this observation is true r

“People underestimate how nasty America is. We’d be better off building colonies in the Sahara than in America.” Radiation on the surface of mars is only ~2.5x the radiation in the ISS. There’s no air there, either. Perchlorates suck for hu
