🚀 Behold the revolutionary concept of "netstrings"—an idea so groundbreaking that it involves...wait for it...encoding strings with their length! 🎉 Because apparently, the world desperately needed yet another way to tell computers how long a string is. 🤣 Next up: #DJB reinvents the wheel, now with more roundness! 🔄

FFmpeg 9.1's new AAC encoder

Anyone else out there noticing that newer tv series shows on physical bluray discs are pre-encoded already to h264, and the quality is bad? Most bluray movies and older (pre-2024) bluray tv shows on discs were in the raw mpeg2video codecs and had the highest quality. I don't mind paying for my physical bluray media but if this is what the RIAA has in store for us then I'm out.

Why does the compiler understand ASCII by default?

The title is an assumption on it’s own, so feel free to correct it/me!

I was experimenting with sanitizing user input, specifically, I was trying to have a for loop remove (skip) certain input. Here is the code:

for (n = strlen(input) - 1; n >= 0; n--) { if (input[n] >= 0x30 && input[n] <= 0x39 || input[n] == ' ' || input[n] == '\t') { input[n] = 0x18; } }  

While the program does behave as I want it to, I don’t understand why it seemlingy by default understands that the various hex codes refer to the character encoding as per the ASCII table. I cated my tablet’s (Galaxy Tab A9+, Android, OneUI 7) filesystem encoding at /sys/fs/f2fs/dm-44/encoding, which yielded UTF-8. If I understand it correctly, the first 128 code points of Unicode are the same as ASCII’s. But according to this article on Wikipedia, there are no hexadecimal references in Unicode, only octal and decimal.

If the underlying filesystem uses UTF-8, and Unicode code points are not referred to by hex, how then does my compiler (Clang) understand what ASCII code points I’m referring to?

Is there some conversion going on under the hood that I am not aware of? I did find a libxml2/libxml/encoding.h, which contains comments about some conversion to and from UTF-8. Is this it? I can’t make head or tails of it because of my limited C knowledge…

In this essay, I investigate the ideas of Stuart Hall in light of my own. Hall and I have many commonalities in the operation of language, but my enterprise is broader and deeper, as his was ostensibly limited to media.

🧠 Interesting new work on #cortical #PopulationCoding: Revah, Wolf, Gutnick & Neef show that the #encoding performance of cortical #neurons is not determined by single-cell properties alone, but by a combination of #dendrite size, #synaptic noise statistics, ion channels, and population size.

After two weeks of wrangling, finally got the next batch of AV1 packages built for Arch into the repo. Should be back on the regular schedule of weekly releases unless something else rears its ugly head.

- Some packages require GCC 15 and absolutely hate GCC 16
- Zig 0.16 is not an option for a lot of stuff
- VapourSynth API v3 C headers are no longer included with the Arch Linux package, so had to grab those from the repo and get them to the right spot

Hey @gianni I was just chatting with @yawnbox about a wild range of tech things, and, since I am starting to host an Immich instance in my home, I am considering to convert all my emails to JPEG XL, and I was wondering if there is a way to do so without risking to lose any metadata.

I am happy to read any links you might have but I need them to be as simple as possible because encoding/decoding stuff confuses me a lot. Not my thing… This is why I found your article explaining how AV1 works in simple words absolutely illuminating! Anyway, I just want to save storage space.

Also, I am a big big fan of Aviator, and I have been following your work for a while. Thanks so much for all of it!

After a ton of compiling, the v2 release is official. Containers all work, the client works, and now I'm gonna relax and watch some YouTube videos. Releases are available on the website though I still need to update the docs with the new "installation" process (much simplified).

Releases: https://git.jamesthebard.net/jweatherly/sisyphus-client-golang/releases

#sisyphus #encoding #programming #golang

The long test is looking good for the `av1an`, `mkvmerge`, and `cleanup` modules, the Golang client is doing exactly what its supposed to which is a welcome change from yesterday. I need to do long tests on the `ffmpeg` and `handbrake` modules next, but I'll handle those tomorrow.

After that, I'll update documentation, release the `2.0.0` client, and deprecate the old client.

Lots of progress and a lots of pain. However, all of the Sisyphus modules have been implemented and I'm currently running a test across the `2.0.0b2` version. The most painful thing I fought was literally tailing a log file. Got lazy and brought in `hpcloud/tail` because it did what I needed it to, but what it _didn't_ do was work well for my application. After a day or two of battling it, I removed it and went with `bufio.NewReader`and a nice `context.CloseWith` setup and now it works every time.

Also added a `PostRun()` call to each module just to have a place to do basic module cleanup if needed.

Learned a ton on this one so far and while annoying at times: it's been pretty fun.

The Sisyphus client rewrite continues after a bit of a break. The `ffmpeg` module is mostly finished and should serve as a good template for `handbrake`, `av1an`, `mkvmerge`, and `cleanup` modules. Logging is progressing pretty well. The config has been expanded slightly and can now pull from TOML files on top of the standard environment variables.
