cfrs··on I Stored a Website in a Favicon
That reminded me of Inigo's "real pixel coding" https://www.youtube.com/watch?v=FvS_DG8yIqQ

A 256b intro coded by placing pixels in photoshop and saving into an exe.

cfrs··on Web3 doesn’t care about privacy
That's a great video addressing many problems of crypto, like

- questionable economy models of NFT games

cfrs··on Media blackout after key witness against Assange admits lying
I doubt there are many Russians who trust current government, I live in Russia and can't recall anyone. Even kids today are mostly opposite to government due to huge information campaigns. Those who deny Soviets crime are mostly misinformed, like US citizens believing in little green men.

cfrs··on Telegram gets 3M new signups during Facebook apps’ outage

cfrs··on What if AI is a failed dream?
Interesting links, though blaming AI does not "solve the problems of today" seems naive. It does.

P.S. Funny that google suggests to search for "what can't we do without AI" instead of "what can’t we do without AI" ;)

cfrs··on TempleOS is applying to Y Combinator. Partners desired, send an email
TempleOS features HolyC: "In other operating systems, I hated learning one language for command line scripts and another for programming. With TempleOS, the command line feeds right into the HolyC compiler, line by line, and it places code into memory it MAlloc()s. The compiler is paused at the command line, waiting for input. Naturally, you #include a program to load it into memory and, usually, start it. During the boot process, many files get compiled before you have access to the command line. (Don't worry, booting takes only a couple of seconds.) All the header declarations for the operating system are compiled and are available for use in your programs without needing to #include them. Everything is truly compiled to native x86_64 machine code, nothing is interpreted and there is no byte code."
