Everyone jumping up about "enshitification". I tried to enable this feature on QEMU and it broke my VMs because the secure memory system was board-line hopelessly broken/non-functional.

Did anyone even use this feature?

Yes it is dishonest to remove features but from perspective AMD disabled a feature that never worked in the first place. The feature never should've been advertised as enabled.

GStreamer is just a different front end to ffmpeg.

ffmpeg's core functionality (encode, decode, streams, pipes, channels) are all implemented in `libav` which gstreamer links against.

Add to the list that martian dust contains a massive amount of carcinogens meaning any air/dust lock has to be an ISO-6 clean room.

Sure it is a "solved" problem but all the solutions are very heavy.

It makes no difference at all.

Edit: Opus prior to the context nerf it worked more often than not. Current Opus 4.7 is practically unusable.

> What it gives me in Swift, most closely resembles stuff that enthusiastic newer folks would do, and want to show off.

The same is true for rust-lang. Code that will immediately clone/re-allocate anything passed by reference and collect everything to the heap that is passed by `Iterator`/`IntoIterator`.

It is a massive performance anti-pattern and the hallmark of somebody "struggling" with the borrow checker. Naturally a lot of 1st & 2nd 'I just learned rust' projects lean on it. Which is totally fine for humans, you're learning. But with LLMs that pattern is now burned into their eigenvectors with the heat of a billion hours of H100 training time.

It has gotten to a point that all code I generate with Opus or Codex if there as iterator or reference in the argument, I start a fresh context, with a sort of `remove unnecessary clones, collections, and copies from the following code: {{code}}`

This is because LLMs don't actually understand language, they're just a "which word fragment comes next machine".

    Instruction: don't think about ${term}

Now `${term}` is in the LLMs context window. Then the attention system will amply the logits related to `${term}` based on how often `${term}` appeared in chat. This is just how text gets transformed into numbers for the LLM to process. Relational structure of transformers will similarly amplify tokens related to `${term}` single that is what training is about, you said `fruit`, so `apple`, `orange`, `pear`, etc. all become more likely to get spat out.

The negation of a term (do not under any circumstances do X) generally does not work unless they've received extensive training & fining tuning to ensure a specific "Do not generate X" will influence every single down stream weight (multiple times), which they often do for writing style & specific (illegal) terms. So for drafting emails or chatting, works fine.

But when you start getting into advanced technical concepts & profession specific jargon, not at all.

> Or is it restricted to 0/1/2 by the shell?

It is not. You can use any arbitrary numbers provided they're initialized properly. These values are just file descriptors.

For Example -> https://gist.github.com/valarauca/71b99af82ccbb156e0601c5df8...

I've used (see: example) to handle applications that just dump pointless noise into stdout/stderr, which is only useful when the binary crashes/fails. Provided the error is marked by a non-zero return code, this will then correctly display the stdout/stderr (provided there is <64KiB of it).

> Commodity hardware and software will continue to drop in price.

The software is free (citation: Cuda, nvcc, llvm, olama/llama cpp, linux, etc)

The hardware is *not* getting cheaper (unless we're talking a 5+ year time) as most manufacturers are signaling the current shortages will continue ~24 months.

docs.kernel.org is generated from in tree readmes, docs, type/struct/function definitions. Making it a lot easier to read/browse documentation that would (previously) require grepping the source code to find.

I realize the site also hosts some fairly out-of-date articles, there is room for improvement. Those hand written articles start with an author & timestamp, so they're easy to filter.

Setting up `apt` to pull from a different repo (to say install firefox.dpkg instead of snap) requires like 3-4 commands which are easily searchable.

I'd had effectively zero issues avoid snaps.

Given the chronostrife will occur in around 40_000 years (give or take 2_000) I somewhat doubt that </humor>

linux core utils have supported this since 2018 (coreutils 8.3), amusingly it is the same release that added `cp --reflink`. AFAIK I know you have to opt out by having `POSIX_CORRECT=1` or `POSIX_ME_HARDER=1` or `--pedantic` set in your environment. [1]

freebsd core utils have supported this since 2008

MacOS has basically always supported this.

Buddy, I have 24Tb HDDs in my pool today.

If anything the opposite has occurred. HDD scaling has largely flattened. Going from 1986 -> 2014, HDD size increased by 10x every 5.3 years [1]. If anything we should have 100Tb+ drives if scaling kept going. I say this not as a but there have been directly implications for ZFS.

All this data stuck behind an interface who's speed is (realistically after a file system & kernel involved) hard limited to 200MiB/s-300MiB/s. Recovery times sky rocket. As you simply cannot re-build parity/copy data. The whole reason stuff like draid [2] were created is so larger pools can recover in less than a day by doing sequential parity & hot-spairs loaded 1/N of each drives data ahead of time.
