I have. In fact, some of my hand rolled stuff is actually _provably_ faster and more secure then even heavily battletested and widely used "industry standard" solutions. This is mainly due to them passing an exhaustive barrage of

Yep. Sorry for the spam, but look at this, compiling "yazi" from source (ie a relatively simple TUI file manager) 676 dependencies: Downloaded by_address v1.2.1 Downloaded block-buffer v0.12.1 Downloaded block-padding v0.4

Due to reflection, technically. Will correct it make it clearer, in order to compile this you need a C++23 compiler (gcc).

Little something I've been working on. To my knowledge this is the only(?) compression codec using Hopf-fibration quotient coding in any way. It's lossy, guarantees fixed rate compression on any input, zero codebook (same as other

I've implemented the same thing for micron (more or less). One advice I'd give you is to _really_ take care regarding SysV/ELF ABI conventions, there's tons of undocumented stuff in there and it's really easy to mes

But the point is that it's garbage because of the low quality of the information, and not necessarily because an LLM made it. I do agree that most people don't know how to prompt.

It's actually insanely difficult to get LLMs not to produce comments. Even with explicit "NEVER LEAVE ANY COMMENTS WHATSOEVER", they still do, across basically all providers.
135.
by rfgplk 2mo ago
Prune the comments? Instruct the LLM to print less comments (this one is genuinely hard though). What's really happening is that you don't have a strong enough review process (or a code standards process) to offset this. The one i

It's an ego issue for most people. For one, part of it comes from genuine intimidation or fear, the notion that a machine can be smarter than you, or at least produce answers that are more knowledgeable than you could. But I think the

Is there any reason why you only target sse2 for simd acceleration? You're leaving a lot of performance on the table.

I've been fighting against the AI detractors for quite a while now but they refuse to see the light. The reason you're seeing AI everywhere is simply because LLM augmented workflows give you _obscene_ efficiency boosts. You need 5

Maybe the person writing the report isn't an expert in this domain or doesn't have the time to commit to it? From my point of view as long as the information is accurate and reproducible, it's valuable.

Why is it unreadable? I actually find LLM bug reports/breakdowns to be far more detailed and concise that classical human written ones. If you read the linked repo it clearly goes it depth where the bug was found, how to reproduce it (

Nice article. There a few issues with your code however from a cursory glance; your dtor seems to allow for spurious/double frees due to custom deleter support (you wanna check up on that), you also seem to use seq_cst far too much eve

C++ is actually obscenely complex, I don't deny that. Just mastering object lifetime rules is crazy difficult due to all the edge cases, but it comes with the territory.

But isn't this a problem with all code? Looking at a Rust function signature how can you be sure that it does what it says it does? Or python?

The standard library implements really do suck (in some cases), but this should be separated from C++ (the language). Even the standard splits the language grammar from the standard library cleanly.
