It's good that you include "shameless plug" in these posts to clarify, but it would be much much clearer if you included more explicit phrasing along the lines of "I only post to HN to plug my project called SaferCPlusPl

I’ve longed for something similar in writing JavascriptCore bindings. Something lighter weight than swig but which still has an IR for describing the full API surface for codegen plugins would be immensely useful.

I talked about this a little bit in the meetup talk I linked and I intend to write a bit more about this, but I'll try to summarize. There are kind of three prongs here: First, using criterion.rs does a ton for giving us more stable me

I use this word the way we did when I worked as a PC technician and help desker, where there's a lot of automation but then we sneak a bit of manual labor in to make it actually useful. Like how user accounts would be maintained in the

I currently do something pretty similar by using the perf subsystem in the Linux kernel to track the behavior of each benchmark function. In my early measurements I found concurrent benchmarking to introduce unacceptable noise even with thi

Each benchmark result is only compared against values from running on literally the same machine, actually. I agree that good results here would be extremely difficult to produce on virtualized infra, so I rented a few cheap dedicated serve

I think this is an interesting exploration because I really enjoyed the description of profiling and improving performance, but I came away feeling exactly the opposite of the title. I think it's really cool that JS optimization can pr

> No. If your language cannot call into a dynamic library using a well-defined C ABI for your platform, then it is already failing to speak a standard protocol. This also involves a marshalling cost at the ABI boundary, which may be lowe

I'd wager that using C prevents large classes of errors that would be common place in assembly. That said, colloquial history seems to say that there were plenty of languages which did a better job at that than C.

By default rust doesn't allow out of bounds indexing (indexing and iteration are checked, although bounds checks are often optimized out), you have to explicitly write unsafe code to read off the end of an array or vector.

Anything involving asynchronous operations has historically been painful with Django. I know that new versions are improving on this, but I think for now it's limited to web sockets.

Nitpick: GC is technically optional in Rust, because you can stick pretty much anything in a reference-counted box or an atomically-reference-counted box (Rc<T> or Arc<T>). It's not the default by any means though.

Only responding to one element of your comment -- but I think that Rust's safety features are over-marketed in my experience. The safety Rust offers is only part of a package that provides high-performance high-level abstractions over

I get the impression that this is a purposeful misunderstanding, mostly for kicks and giggles. Maybe I'm wrong? But it certainly seemed tongue in cheek to me, aimed at bringing a fresh perspective to a work that's already been p
