A little bit too concise IMO. E.g. it doesn't really explain where the normal equations come from and it mentions eigenspaces without ever defining them.

What are some others?

I did make sure to check before posting. Good point about the signed integer overflow, though!

I used GCC and checked that it wasn't optimized out (which actually surprised me!)

Very cool idea - but unless I'm missing something, this seems very slow. I just wrote a simple loop in C++ to sum up 0 to 2^30. With a single thread without any optimizations it ru…

A couple details worth noting: - `repr` often outputs valid source code that evaluates to the object, including in the post's example: running `datetime.datetime(2023, 7, 20, 15, 3…

Do you have a source for that? I thought it was closer to 5pJ/byte.

I enjoyed the easter eggs!

(Yeah, I was not a TA then -- I took it under Paxos in Spring 2014 but only TA'd it after the switch to Raft)

As someone who TA'd 6.824 (Distributed Systems) twice, I 100% agree. It's easier to halfway understand Raft than to halfway understand Paxos, but implementing a consensus algorithm…

This sounds like you're describing energy-based models, not diffusion models.

I think you misread slightly. > All of these algorithms take constant time, i.e., time independent of the input coefficients for any particular (n, c). This means that once you hav…

Oh, good point, I didn't read what you wrote carefully enough.

Actually, the illegal memory access would be undefined behavior, so it's fine for the compiler to assume that it's living in a world where the segfault never happens. Thus, it can …

The center core is new, but the side boosters are both recycled. See https://en.m.wikipedia.org/wiki/List_of_Falcon_9_and_Falcon_...

I enjoy MealSquares: http://mealsquares.com . A bit expensive, but fulfills many of the same objectives.

The very same airport, in fact. They accidentally turned off auto-throttle and took far too long to react to the falling airspeed.

I think you mixed up m/s and km/s. The speed of light is 300,000,000 m/s, so 30,000 m/s is only .0001c. At 1g, it actually takes a month to reach .1c. (Still, your point stands.)

Wow, can I read more about the circum-planetary superconductor idea somewhere? I thought this sort of thing wouldn't work because superconductors lose superconductivity once curren…

To get the key ideas behind many of these topics, you could try reading Evan Chen's Infinitely Large Napkin: http://www.mit.edu/~evanchen/napkin.html

I believe you use timing differences, not parallax (it takes ~40 ms for gravitational waves to travel through Earth).

Wasn't TSX only enabled on Xeons to begin with?

That's assuming that they're independent, though, which is certainly false. I'm curious by how much.
