00:48:44 <fizzie> int-e: Added TikZ support to the "images-to-embed-in-Markdown" utility I've got in the AoC repo so that I can spend far too much time fiddling with illustrations like https://0x0.st/o52y.png
00:50:21 <FireFly> nice
00:50:25 <fizzie> Also plotted the day 20 benchmark results in a neat plot [ https://0x0.st/o52t.png ] and made a diagram to illustrate the day 15 coordinate transformation [ https://0x0.st/o52v.png ].
00:50:36 <fizzie> Think I might have LaTeX withdrawal or something.

09:30:59 <int-e> fizzie: Btw, belated realization: For yesterday's part 1, I should've just copied the input to a Haskell file, replaced : by = and / by `div` and finally added `main = print root`
09:35:19 <int-e> And then https://hackage.haskell.org/package/simple-reflect-0.3.3 for part 2.
09:35:55 <int-e> (that's enough to produce an expression that can be fed into a CAS)
09:36:20 <int-e> that would've been really fast, had I thought of it :)

10:44:00 <int-e> Also... poor programmer here tried to write branch-less code, should've used `if` instead. https://github.com/Neptune-Crypto/twenty-first/pull/70#issuecomment-1362677843
10:44:26 <int-e> (ultimately that may be a shortcoming in LLVM)
10:46:46 <int-e> (The code they wrote was `let (r, c) = xh.overflowing_sub(b); r.wrapping_sub(0u32.wrapping_sub(c as u32) as u64)`; I rewrite the second instructions as `if c { r.wrapping_sub(0xFFFFFFFF) } else { r }`
11:29:14 -!- wib_jonas has joined.
11:30:26 <wib_jonas> int-e: er, so that's not in a context where the code should be constant time to avoid side channel attacks, and that's why the programmer used branchless code?
11:30:58 <int-e> wib_jonas: I dunno, I think at this point they just want it to be fast.
11:31:41 <int-e> But that's a guess, it's just as well possible that you're right.
11:32:19 <wib_jonas> it's some cryptography stuff, and most of cryptography wants to be constant time unless it's a cryptanalytic attack
11:34:45 <int-e> They're sword_smith on this server and they're in #crypto; you could ask ;-)
11:34:50 <wib_jonas> as far as I understand, in theory you basically can't make anything constant time on normal consumer processors and consumer operating systems, but in practice all the symmetric crypto is trivial to make constant-time as long as you just use constant-time comparisons when you compare digests, while public key cryptography is hard to make constant
11:34:50 <wib_jonas> time and designing primitives that can reasonably be implemented constant time is a significant part of the dark art of cryptography
11:38:01 <int-e> Actually... AIUI the context is zero-knowledge proofs; I don't think constant time is a requirement for that.
11:40:01 <wib_jonas> what? it's not zero-knowledge if you're leaking timing information
11:40:54 <int-e> oh, non-interactive zero-knowledge proofs, I should say
11:41:19 <int-e> The fact that those exist is absolutely mindboggling to me.
12:38:08 -!- tromp has quit (Quit: My iMac has gone to sleep. ZZZzzz…).
12:43:18 <FireFly> I need to read up on how they work, but I recently learned about zero-knowledge VMs and RISC zero, which definitely boggles the mind
