Matt Pharr recently released an early version of PBRTv4, which has been rewritten extensively to make heavy use of Optix and the GPU. Given that he previously wrote a series on rendering Moana using PBRTv3, I wonder if v4 could be used as a

Is it possible to "read out" whatever logic the FPGA was previously programmed with? If the speculation that it came from the Bing accelerator is correct, you might end up with some interesting code...

You can do very well with just Google Colab. If you prefer local compute, the higher-end NVIDIA gaming cards (GeForce series) will do pretty well.

I've taught OS three times using xv6 and like it a lot. It's very small, which is great. You can print out the entire source code (and there's a makefile target that will produce a printable PDF) and read through it and actua

Were you able to MITM the api.apple-cloudkit.com connection? I tried with MITMProxy but ran into a client error, which made me think they were doing cert pinning. If you did get it to work could you paste the logs somewhere?

Hmm, I thought cryptarch was just crypt + arch with the arch part meaning “leader” (i.e. this sense https://www.etymonline.com/word/arch- ), not archaeologist. Is there something about this in the Quantum Thief trilogy

Just one, and that's roughly the right ballpark.

If I remember right, after the leaks the faux-sophisticated take was "well of course , everyone knew this was going on, are you naive?".

One odd bit of trivia: the Windows system call mechanism supports up to four different tables. The first two are what you'll usually see - the first is the basic kernel services, and the second is for Win32k, the graphical subsystem. T

Well, fuzzification is implemented as a compiler pass, so I feel like this is asking whether it's better to invest time writing better software or using -O3. In principle you wouldn't need to spend developer resources on it.

It's semi-common (or was, in the 80s) for couples who didn't want to change either of their names to instead give their kids a hyphenated name with both the mother's and the father's name. So my mother's maiden name

This has always been a funny "secret" to me since I have a hyphenated last name – gee, my last name is "Dolan-Gavitt", I'll give you two guesses what my mother's maiden name is.

Yes, I do think that it learned a model of PHP and JavaScript syntax. 40GB of text data is a lot , and PHP syntax is a lot simpler than English grammar, which it learns quite well. See also the example in the paper of accidentally learning

Yeah, the dataset was 40GB of text from pages linked from Reddit, so I imagine it was quite hard to clean it to just English text. They also noted in their paper that it "accidentally" learned to translate English into French, e
