Thanks for sharing! This will definitely be interesting to look at :)

Just to clarify, 5.85 ms and 11.8 ms are the data points of the baseline, so complexity is indeed linear there. The Elixir implementation, though, runs in 225.4 ms (39x slower) and 664 ms (56x slower). Thanks for pointing out the mistake in

I don't know exactly how the word breaking algorithm works under the hood, but the Rust library I am using seems to have linear complexity, so it should be possible to improve unicode_string (if someone is willing to dedicate the time)

I agree with both of you :). Sending an opaque binary blob and reassembling it at the other side would have been ideal... but with some of the third-party systems we integrate with it is not possible

Thanks! Hopefully we are safe then :)

Interesting, I wonder how they could make a case for that. Do you have any references? I have heard of developers independently reimplementing GPLed code, being careful not to read a single line of the original code to avoid any chance of t

It doesn't mention the JNI because I didn't use it (the Java implementation was from scratch and did not include native code)

Thanks for mentioning Postgres! I am actually pretty curious about the difference between MySQL and Postgres when it comes to their docs about the protocol. My superficial impression is that the Postgres docs are more thorough, leaving less

This is a writeup about one of the most interesting contracts I've done. The resulting implementation is (unfortunately) not open source, but I'm hoping it will be eventually!

I wrote this about three years ago, intrigued by optimization and solvers in general. The technology is interesting, but every time I try it out I end up with the impression that you need to deeply understand it in order to use it effective

You are right, this much more ambitious than I though! Here is more information about the project, for the curious: https://rust-gcc.github.io/

I think this is more of an attempt of making Rust compilable on platforms not supported by LLVM, not an attempt to replace the existing compiler. The GCC frontend, for instance, does not implement the borrow checker, so you should only use

Haha I have certainly thought about that possibility ;) You can do incredible things with little effort thanks to Rustler

Personally, I'm finding myself reaching for C# to solve most problems I come across. Rust is appealing to me on a more theoretical level (or when there is a domain where it truly shines, such as concurrency or C-like performance). IMO

Great to see people found my article interesting! I wrote it after I was asked by a company about the possibility of helping them by contributing to some open source Rust projects. During the conversation I tried to explain my involvement i

Just wanted to say thanks too. Back when I was at the university, your blog helped me discover programming languages are something you can actually design. I even ended up contributing to the Rust compiler, which was an incredible learning

Hi there! This is a totally off-topic comment, but since there is no way in HN to send private messages, I though I might as well reply to your most recent comment. I have been enjoying your comments about being a craftsman and working in a

3 days a week is definitely doable, at least as a contractor (source: that is what I am doing right now, and I even have the luck of being able to choose between two companies for my next engagement)
