Ultra-low-sulfur diesel became mandated in 2006 as the only type that was legal to sell for road use. That requires extra refining to remove the naturally-occuring sulfur from the fuel which is why the cost went up.

The answer is pretty obviously AV1 if you care about delivering content to actual end-users, unless you expect them to be severely bandwidth constrained such that the ~30% improved efficiency makes a noticeable difference. AV2 is still no

Why shouldn't they get 6 MHz? My PBS station broadcasts 4 subchannels: the main PBS channel, PBS Kids, a channel with programming about our local region (which airs live coverage of our state legislature when it's in session), and

Only the asymmetric portion of the cryptography (which is only used in the handshake) will need to use PQC algorithms. Symmetric crypto algorithms (AES/ChaCha20/SHA-*), which are used after the handshake, are not as badly affected

Post-quantum algorithms tend to be slower than existing elliptic curve algorithms and require more data to be exchanged to provide equivalent security against attacks run on non-quantum computers.

Along similar lines, Mozilla recently updated their recommended server-side TLS configuration to enable the X25519MLKEM768 post-quantum key exchange now that it's making it into actually-deployed software versions: https://

Users care about quality, even if the people buying the software do not. You can't just say "well the market doesn't care about quality" when the market incentives are broken for a paricular type of software. When the

Every generation of the production Nissan Leaf has used lithium batteries. AFAIK no modern (~post-2000) mass-produced (>10k units sold) EV has ever used NiMH or lead-acid batteries. Edit: Checking Wikipedia to verify my information, I fo

Yeah, AV1 is primarily based on what Google was working on for their own successor to VP9, what would have been VP10, with technology contributions from Mozilla/Xiph's Daala and Cisco's Thor codecs.

Seriously. Also less and less software is supporting 7. Importantly, Firefox ESR 115 is the last modern browser to support Windows 7 and it's entering EOL after this month[1]; Chrome dropped Windows 7 support in 2023[2]. [1] https:&#x

There is a port of Mbed TLS to Classic MacOS[1] which has TLS 1.2 enabled but per the README.md probably not the right cihper suites (it only has AES-CBC ciphers enabled by default) to connect to servers configured per the widely-used Mozil

The D language basically does that. You can write D programs that evaluate D code at compile time to generate strings of new D code which you can then basically compile-time eval into your code as needed. Combined with the extremely powerfu

That's C++11 syntax. Before then you'd have to manually initialize them in every constructor, with a hand-written default constructor as a minimum: struct test { int my_int; int *my_ptr; test

It enables shorter traces between the CPU and memory chips which allows for higher speeds compared to the traditional SO-DIMM form factor. And the compression is physical (the socket works like modern LGA CPU sockets).
