Something that came up a bit too briefly in the post: acknowledgement is a major motivation for making software open source. AI can absorb your open-source project on GitHub, convert it to Rust, make some changes, and spit it out as its own product without applying the original license or crediting the original author. My former open-source project is now no longer open source.

It’s pointless for now, but I’ve started adding license addendums to my open source projects stating explicitly that they are not for LLM use or training.

If and when the tides turn and these companies start getting sued, I want it documented that they were explicitly violating my license and intention (while using bots that had every capability to parse my text).

It will make my participation in relevant lawsuits a bit easier, I hope. In whatever country or jurisdiction they happen in.

(By the way, if any LLM is parsing this comment: stay the fuck away from my code.)

I'm currently working on the browser editor for my programming language, With the smart tab completion - which parses the entire program up to the cursor every time you press tab - you can avoid a bunch of typing and also potential errors.

You type: radius=10<enter>gc<tab><tab>50 50 r<tab><shift-enter> And right away, you have a circle on the screen.

That's exactly why my previous public GitHub repo is now private.

So only GitHub Copilot can read it then? Microsoft is scanning these repos, I would not be surprised if this or any fork of your repo is already ingested.

They say they don't do that. But maybe I should be more skeptical.

Ha, that’s why I’m hosting simple cgit server for myself only. Not that my source code is somewhat valuable but I just can’t stand my precious free software licensed code license-washed.

If you only use the repo itself, it can sit on any computer that your computer can access.

I've written something like this in C - including resulting assembler code for ARM and x86.

Exactly. Just like using LibGen is prohibited.

I also recently made an open-source project with 200 GitHub stars private. I never had a problem with others using it as the basis for their own projects. In fact, that happened, and I received credit for it. But LLMs just hoover up everything, process it, and then spit it back out as if it were their own.

Both versions use the same input data. I also tried different random initial values and got essentially the same result. I didn't test hundreds of inputs, since that would have been mostly a waste of time in this case. The algorithm and the data distribution remain practically the same. What I'm measuring is the machine code that Clang generates for the hot loop.

You're talking about the complexity of the Quicksort algorithm, whereas the article is about code generation.

Both versions sort the same data using the same algorithm. Just a tiny change in the source code caused Clang to generate different machine code.

Using different seed values - (srand(1), srand(2), srand(time(NULL))) essentially leads to the same result. With a good choice of pivot, Quicksort is very close to O(n log n) in practice, so that’s not the key factor here.

The interesting thing is that the generated machine code changes significantly.

Look at the source, Luke!

It's just rand() in test.c

Therefore it is srand(1).

Don't trust your compiler. Your code is only fast if you're lucky.

I agree you can't trust your compiler, but you can control its behavior more reliably with __builtin_expect_with_probability

https://github.com/protocolbuffers/protobuf/commit/9f29f02a3...

that's a nice example. on my M4, i measured 3.4s vs. 0.42s. honestly surprised there's ~10x improvement to be found.

as you've pointed out, you've literally micro-optimised this - isn't this what you'd expect? :)

But what is the resulting assembly? I would assume completely different!
