Reminder: AI "generated" code is 100% plagiarized. You must not accept code of unknown provenance into your code base. Doing so opens you up to potential copyright infringement lawsuits. Nobody needs a repeat of the SCO vs IBM lawsuit over ownership of Unix.
Accepting AI-assisted code is just legally untenable. That's black and white, there's nothing to debate. Projects that accept it are idiots and should be shunned.

hm, this makes me think of setting up some servers in local libraries. And maybe automatically issue accounts when people sign up for a library card. I wonder who to talk to to organize such a thing.
The local library probably has better internet service than most homes. They already give free wifi access to card holders. I wonder if it makes sense to set them up as email & messaging providers too.

yes and no. Adobe's proprietary RTMP streaming protocol also includes commands for pause/rewind/seek so you can skip around in a stream, much like controlling a VCR. It also controls its transmit rate to match the bitrate of the media. (So even if you have a very fast connection, you receive the data of e.g. a 2 hour video in ~2 hours.)
But "streaming services" that just use HTTP - yeah, they're exactly that, a download without a Save option.

your generic statement "closed source software isn't a black box" is generally false. You could have just said "iOS isn't a black box".

2025-12-06 09:04:37 UTC

- reply

You keep repeating "closed source software is not a black box" but in most cases that simply isn't true. Proprietary software companies go to great lengths to impede attempts to reverse engineer their binaries. One of the reasons proprietary apps are so bloated is because their code has been processed by an obfuscator, which replaces simple instructions with long sequences of mathematically equivalent code that takes thousands more instructions.

2025-12-06 08:56:25 UTC

- reply

the compiled output of proprietary code is often obfuscated to prevent reverse engineering. E.g. Adobe binaries are intentionally obfuscated. Saying closed source code can still be reviewed drastically misrepresents the difference in difficulty.

This Open Source Mobile Comm project appears to be an open source impl of a 3G network's backend software. But they're not using the standard 3GPP protocols, they're using their own home-grown stuff instead.
Looks like a toy, using SQLite3 as its HLR storage. Real 3G/4G networks use LDAP, lots of OpenLDAP in particular because nothing else scales enough, efficiently enough.

switching automobiles to full EVs would remove the majority of oil consumption. So yes, a change of technology will have far more impact than a change of lifestyle. Yes, reducing automobile use and emphasizing mass transit will be even better, but those transit projects will take multiple years.

most coal is burned to generate electricity. A transition to solar+wind and other renewables would take a huge chunk out of our CO2 emissions. Rooftop solar could be a big part of that, and I suppose that's more an individual choice right now but it could be made systemic by policy. But once the decision's been made, you can go on living same as before. Better usually, because less of your income will be spent on power. https://ourworldindata.org/grapher/co2-by-source

by the way, fyi, a Twitter engineer wrote an #LMDB backend for #git back in 2015. https://lore.kernel.org/git/[email protected]/
"The [LMDB] backend runs git for-each-ref about 30% faster than the files
backend with fully-packed refs on a repo with ~120k refs. It's also
about 4x faster than using fully-unpacked refs. "

SQL is too heavyweight for the simple things most apps need to do with storage. SQLite is no different, spends too much time in parsing & interpreting queries.

Funny that this is "Intel's response" when they spent so many years leading and defining the market.

a watt-hour is literally watts * hours. A 500Wh battery can deliver a sustained 500W of power output for 1 hour.
How much energy you need in battery storage depends on much power your motor can draw and how much time you need at full draw. Running at less than max wattage should give you longer runtime, as well.

PS: if you read that paper and came away thinking "wow, mmap is really bad" instead of "wow, these authors never proved their paper's thesis; they have no fucking idea what they're talking about" then your critical thinking skills need work.
The same is especially true of the morons who peer-reviewed the paper. Well, they were obviously their intellectual peers, anyway.
