csmantle··on Show HN: Header-only GIF decoder in pure C – no malloc, easy to use
Probably it's better to mark every functions as static in a header-only library, not just those internal ones. But I think code bloat would still be an issue if we don't use LTO or other optims across compilation units.

edit: Yeah, defining *_IMPLEMENTATION appropriately would address these issues.

csmantle··on Brave blocks Microsoft Recall by default
A side note: there's a group policy "Allow Recall Enablement" that, it claims, when disabled "the Recall component will be in disabled state and the bits for Recall will be removed from the device".

csmantle··on Show HN: ggc – A terminal-based Git CLI written in Go
From the GIF in the repo I think it's somewhere between CLI and TUI -- it's interactive but does not try to draw windows/surfaces in the terminal. But the borderline is fuzzy, so yeah

Apollo won't ever make it to the Moon if the engineers were flooded with these bot replies XD
csmantle··on Where's Firefox going next?
No, thanks. After I finish my task on my browser, I would take a break offline rather than indulging into an endless stream of "You May Also Like". Actually, I would thank FF for not filling their homepage with these noises.
csmantle··on Where's Firefox going next?
I kind of prefer TST since it's tree style. The native vertical tabs is flat, but I would like to organize my tabs more hierarchically.
csmantle··on Hacking Coroutines into C
Yeah. Protothreads (with PT_TIMER extensions) is one of the classics libraries, and also was used in my own early embedded days. I was totally fascinated by its turning ergonomic function-like macros into state machines back then.
csmantle··on What every programmer should know about how CPUs work [video]
The Matt Godbolt behind godbolt.org? Wow.
csmantle··on Show HN: I made Logic gates using CSS if() function
If we can introduce delay in the circuit it would be trivial to build FFs from Boolean-complete gate sets, thus sequential elements with memory. But AFAIK CSS if() can't introduce delays.

Unfortunately the examples provided by OP only contain combinational circuits, which by def. have no memory.
csmantle··on I Spent My Weekends Building an AI Debugger That Understands Your Code
This is an very exciting idea -- combining current symexe engines and CFG/dataflow analyzers with LLMs is indeed a promising topic.

Can't wait to read the code!

csmantle··on Show HN: Meow – An Image File Format I made because PNGs and JPEGs suck for AI
This approach tries to combine pixels stream with metadata stream, but from my opinion that's not a very elegant solution.

Being consistent when perceived and being lossless in information are different things. https://github.com/Kuberwastaken/meow/blob/60339a764a2365c4a... shows that the library simply truncates the lower bits of the pixel, doing a lossy transformation to the carrier. This could lead to (at best) inconsistencies in later sample processing, or (at worst) the sample being pulled away far from the original location in the sample/embedding space.

Steganography is generally used to covertly carry information -- you try to keep your extra bits in-band with the carrier. That's why anti-piracies use that to carry identifiers, watermarks or so, without disrupting the perceived consistency/quality of the carrier.

Metadata, on the other hand, does not need to be transmitted covertly. They are public information can be included in the container format itself. Many image formats already have facilities for these out-of-band data streams. So I think it's reinventing the wheels, but in a crude and complicated way.

Definitely the `import this` for Rust -- a curated reminder of what Rust shouldn't be.
