I resent retail music now. I don't want to hear rock music from my teens at home depot. I don't want to hear christmas music before thanksgiving at target. If physical retail were actually humanized, it would play whatever the employees want to listen to.

I think this incident reflects badly on the broader institutions currently covering AI and the environment. I should absolutely not have been the first person to notice this. From the end of the post:

In case people want to know what those funky hashes are in Nix thingies, those are the raw binary hashes converted to base64.
So, for instance, if you are using the experimental blake3 support, you can do
b3sum --raw file.tar.zst | base64 | head --bytes=-1 | sed 's/^/blake3-/'
#nixos

I just remembered about “David’s Sling” by Marc Stiegler. It was written in 1988. When I read it, probably a decade later, the political setting was embarrassingly obsolete and the tech was ridiculously speculative. But now I’ll bet they are both juuust right.

if you for some reason think this is useful:
1) why. why would you use this and not something like ChaCha20Poly1305.
2) this is an exceedingly bad toy impl written by someone with no cryptography training. there seems to be better constructions of BLAKE3 AEADs than.... this bullshit

keyed blake3 XOF is basically a stream cipher, keyed blake3 is literally a MAC, I can make an AEAD out of this, so I did just that gist.github.com/vgskye/6253a...

I like this essay. Global namespaces are attractive to software engineers and businesspeople, but not because they are good for users. We need instead to work for the opposite goal: to increase the user’s illegibility.

There’s an idea that is widespread among software engineers that goes: “Sure BLAKE3 is faster in software, but CPU makers put dedicated hardware for SHA256 into their CPUs so SHA256 is faster than, or at least as fast as, BLAKE3 practice.”.
This argument is mostly mistaken. …
