I'll give you the Eye of Sauron example. I admit I haven't read the books, and I've seen the films once or maybe twice. For the other examples you mention: As ximeng mentioned, "ocean depth" here should refer to sea

They're certainly meant to be entertaining. I really don't think they're meant purely as jokes, though. And which are the trick questions with trivial answers? I can't recall seeing any of those. Any question that is poo

And I'd like to plug my favorite twitter account, Wolfram|Alpha Can't: https://mobile.twitter.com/wacnt/ It's a collection of queries that an AI could answer in theory, but are (probably) far beyond curr

I wrote something very similar some years back: https://github.com/zwegner/prethon/ I can't remember if I saw Cog first, and wrote a different version that fit my needs better, or if I only found Cog afterwar

While I agree with you, I will note that even set union in Python is not commutative. a | b should equal b | a in the sense of __eq__, but the actual objects in the result set depend on the order of the arguments (and in the opposite way fr

It actually would've been during my time at Intel working on the graphics stack for Larrabee, in the 2010-2011 timeframe--vcompressd was part of LRBNI. I was mainly doing infrastructure/compiler/optimization type work, and no

Wow, not bad! I'm looking forward to the writeup. I'm still thinking about this one. It seems that ~.5 cycles/byte is slower than it should be. There's 6 pext->kmovq->vpaddb chains, where the pexts and kmovqs are a

Hi there! Thanks for the nice writeup and successfully nerd-sniping me! :) You can absolutely use the code. Good tip on the SDE too. I had heard of it but didn't realize it was so lightweight, dynamically patching the binary to emulate

Oh sweet! That's an awesome instruction. I'd imagine that would be useful for lots of things. I believe I've seen vcompressd before, but totally forgot about it. Unfortunately it looks like the byte-wise version is part of AV

Hmm, interesting idea. The main problem I see is that PEXT can only move bits from within an 64-bit operand, so we can't operate on the 512-bit vectors anymore, AFAICT. We'd have to split the loop up into 8-byte chunks instead, an

by zwegner 8y ago
Interesting, I started out thinking along these lines, but once I figured out I could use PEXT, I just went with that. I think this approach needs some tweaks, though. Mainly that the vpermb at the end is the inverse of what we want--the by

Awesome, thanks! I'll play around a bit with the algorithms and see if I come up with anything neat. I'll email you if I do.

Ah, just figured it out. I accidentally deleted this line: len = 64 - __builtin_popcountll(mask); So the destination pointer never got updated. Mental debugging is kind of annoying :) Thanks!

by zwegner 8y ago
OK, I got nerd-sniped here. You can actually construct the indices for the shuffle fairly easily with PEXT. Basically, you have 6 64-bit masks, each corresponding to a different bit of the index of each byte in the 64-byte vector. So for ma

That's a real nice track, thanks for that. Admittedly, in the music I posted there's definitely roots in dubstep, neuro hop, glitch, etc. So it's not necessarily a "new" genre, and those tracks could have feasibly b

Thanks for these recommendations. I already really like Yussef Kamaal, and from a short sampling these other artists will definitely make it into my rotation. I feel I should also point out that Coltrane went much further than the sort of j

There's really quite a lot, if you know where to look. One particular genre I enjoy is experimental bass music, that tends to emphasize extremely detailed sound design and production. Every song will generally sound completely differen

Interesting, thanks for the actual-lawyer perspective! So is it that ToSes are less legally binding than copyright law? Or is there special meaning behind " can't grant that right"? Seems like a clear abuse of GitHub's

First off, when did "blockchain" become an uncountable noun? "blockchains" or "blockchain technology" sounds much more natural. Anyways, I wish more people in the media would differentiate between the Merkel tr

Saw this page linked from slatestarcodex.com, and was immediately nerd-sniped. I read through the entire history and was amazed by the depth and variety of all the different queries, some of them quite amusing. Pretty mind-opening to think
