Good list. A few more for me: * Implementation/header pairs in C++ * Language REPLs (e.g., Python) * Quick calculations in Calc while coding * Checking dates on the calendar * Magit status * Diff buffers (esp

It was fun to try to golf this a bit with Z3Py. I'm not an expert at writing for Z3, so it might be possible to do better, but here is a solution in 7 lines: import z3 res = [("bbababbabb", 7), ("baaababaaa&qu

Having implemented DDA code a bunch of times, I find it easiest to think about it in lazy functional terms: it's like a takeWhile on a merge (or union) of infinite ordered streams of ray t-values. In other words, decompose the problem

I find that building and testing my code with -Ofast and -ffast-math from the beginning helps to avoid a lot of the issues with them. Any new code that breaks with them on probably wasn't particularly stable anyway and should be retho

Yes, not so much because I'm trying to anthropomorphize it or interact with it like a human, but because I view such things as conversational signals that may influence the direction of the model. - "Please" = Call to action

Oddly, trying to occasionally place on the Advent of Code global leaderboard was the thing that got me most fluent in Python as its own language. Before that, I tended to write Python in a much more imperative style, since C++ is my main la

In graphics, we also often try to avoid any kind of rejection sampling because it wrecks importance sampling.

I was going to mention the Shirley and Chiu mapping. A copy of the original paper can be found here and is nice and easy to read, with pseudocode: https://web.archive.org/web/20190223095317id_/http://pdfs

The funny thing is, in my neck of Seattle (the city this post is complaining about), I've seen some of the harsh white LEDs that went in switched over to a warmer color. I remember being quite shocked when I pulled into a city-owned p

Neat! I remember contributing the expression parser code for the Knoll et. al 2009 work that you cited in your SIGGRAPH paper. That just rewrote a single user-friendly expression into nested function calls to our IA library in GLSL, witho

As I understand it, that's how the original MMX got started. It was largely reusing the x87 ALU, but breaking the carry chains at the obvious points.

Yep, I've taken several three-week vacations and it's never been a problem. The main thing is just giving plenty of advance notice (and reminding people as it gets close) so my manager can schedule around it, and making sure proj

The big ones for me with log/printf debugging are: - I can get a good idea of the temporal behavior of the program, and I can just scroll up to see earlier state, rather than having to restart the program in the debugger. (I know that

Came here to say exactly this. I've noticed that when I'm standing at my desk, I'm much more likely to start walking around the room, go look out the window, or go pet the cat while thinking something through.

Anecdotally, my cat's definitely know the word "Greenies" for their favorite treats. Fairly recently, I was calling one who was napping to let her know I was about to dispense them. She woke up, lifted her head, perked her e

Crazy thought: something like BorgBackup. If only 20% of the content gets changed, the rolling hash that Borg does to chunk files could identify the 80% common parts and then with its deduplication it would store just a single compressed co

That was the first alternative that I thought of. Experimenting with this: int sign_extend(int val_11b) { struct { int v : 11; } t = { val_11b }; return t.v; } in Compiler Explorer produces pretty much the same

Historically, Pixar's RenderMan defaulted to a 2x2 Gaussian filter [1], and from what I can see, that hasn't changed [2]. Essentially it uses a truncated isotropic (non-separable) Gaussian defined by exp(-2.0 * (x*x + y*y)) with a
