Pardon my ignorance, but doesn't a byte-by-byte output recreation of the C++ code in Rust defeat the whole purpose of using Rust? For one, would it be idiomatic Rust anymore? Also, if there's a (non-memory related) vulnerability in the C++ code, would it be possible for that to be introduced in Rust too?

The impression I get from the article is not that the compiled code of each implementation produces the same object code, but that when the implementations are run with the same inputs, they produce exactly the same output — that is, the same JS VM bytecode.

That matches my understanding too.

If they had developed a technique to get a modern C++ compiler and rustc to generate exactly the same output for any program (even a trivial one) I think that would be huge news and I would love to see all the linker hacking that would involve.

> I guess more anti-hype, where Rust was the hype Yeah that is the thing I struggle with. I am really happy for people falling in love with Rust. It is a amazing language when used for the right use case. The problem is that had my Rust adventures a few years ago and I am over the hype cycle and able to see both the advantages and disadvantages. Plus being generally older and hopefully wiser I don't tie my identity t…

I have literally never heard this, in ~decade of working with Rust. I think you may be taking some random mailing list discussions a little too seriously

It depends. I migrated a 20k loc c++ project to rust via AI recently and I would say it did so pretty well. There is no unsafe or raw pointer usage. It did add Rc > wasn't very difficult, but keeping the code structure identical at first allowed us to continue to work on the c++ code while the rust port was ongoing and keep the rust port aligned without needing to implement the features twice. I would say modern c++…

I can't stress out how much important this sentence is. I would even remove the "familiar with rust" part.

Anyone who still thinks it's good to use C/CPP on modern hardware where Rust support is available and good: please print the sentence above and post it all over your place.

I still don’t buy this “safer more modern” mentality. Modern C++ pretty much solves the safety issues. People need to learn how to use tools properly. If you ask me, Go is a better Rust. Rust is an ugly version of C++ with longer compile times and a band of zealous missionaries. I mean the keywords mut and fn very annoying to read just get rid of them or spell the f*n thing function.

If C++ died for services under Unix and medium sized indie games (such as I2PD, or Cataclysm DDA and its forks) and these where rewritten in Go the maintenance would be far greater in these projects. A GC, a much better cross compatibility and your code for sure could probably be compiled in 10 years. Also CDDA:Bn wouldn't damn need a > 40h long build using 1.5 GB of RAM under an n270 netbook. Ditto with Nchat, FFS,…

As for Go minimalism can anybody explain why logcli is so big https://github.com/grafana/loki/releases just to download logs from kubernetes?

I'm looking forward to RAM production increasing, and getting to a point where every high-end PC (workstation & gaming) has a dedicated NPU next to the GPU.

Wasting electricity to "generate tens of thousands of lines of useless code" at will? Why is that in any way a desirable future?

Wait until you find out about video games.

Any terminal tool like Claude Code or Codex (I assume OpenCode too, but I haven't tried) can do it, by using as a prompt pretty much exactly what you wrote, and if it still wants to edit, just don't approve the tool calls. One problem I've noticed is that both claude models and gpt-codex variants make absolutely deranged tool calls (like `cat > foo...EOF` pattern to create a file, or sed to read a couple lines), so i…

No, not necessarily. It's the ratio and for most basic research the numerator of the fraction is also approaching zero.

Yes, necessarily. Basic research is currently useless in the same way building something that hasn’t been built is currently useless.
