If you're exporting assets for a game, and the swap would be significant, shouldn't it really be generating big or little endian depending on the target? Many audio engines do this, using e.g. RIFX on big endian targets and RIFF o

I guess because the implementations aren't intending to support a lot of different input codecs, so there's no benefits to the flexibility of AIFF/AIFC. Also avoids having to deal with an 80-bit extended precision float just

Looks like this fixes the issue raised in the last discussion [1] by no longer re-quantizing the decoder state at the start of every frame. I still think it's not worth the extra complexity over a simpler fixed set of second order line

For model checking Alloy might be a better example, it directly builds SAT instances (through the Kodkod constraint solver) that are then solved with a SAT solver. I don't think the standard TLA+ checker (TLC) uses SAT explicitly, thou

Given how large the frames are in QOA, it doesn't seem like too much overhead to have the full history and weights stored per frame (if seeking to any frame is required).

This bit > What makes QOA work is 1) a reasonably good predictor and 2) storing the scalefactor for a bunch of samples explicitly instead of guessing the right one from context, like ADPCM does. suggests a comparison with DVI/IMA AD

Looks like it might work up to 16 MB? # If you have more than 2MB flash, you need to change the flash size by adding -DFLASH_SIZE_MB={one of 2,4,8,16} here. 2MB might be a minimum, as the standard bootcode needs 1MB + 4KB. See my boo

The example that comes to my mind is that Square hired Iranian-American Apple II expert Nasir Gebelli to program their Famicom games.

I haven't tested but I would guess it's a whole lot faster to compute but will end up sending much more data, given that it only works via exact chunks. A big part of binary patching is finding the largest possible chunks, even if

I used to use the W alias whenever I noticed myself doing it on a new setup, but I haven't had to do it recently. I suspect my "slow on the shift" issue was due in part to the lousy keyboards I used to use.

Yeah I have one like that (Oxo brand), the sieve seems to work better for me.

A public key signature works by encrypting the hash with the private key, to verify you decrypt the hash with the pubic key and check it against your own hash of the payload. Edit: No argument with your second point, just pointing out the m

Neat idea. I'm imagining something like an FPGA or MPPA [1], where you program an interconnect (pipes) between dozens of available cores (processes), which can be configured to do one of a few hardcoded types of stream processing (comm
