Corning invented a particular kind of borosilicate glass about a hundred years ago and called it PYREX™. They left the consumer goods market about twenty years ago, divesting the brand. Nowadays that name might refer to either borosilicate

Cook County MN is a little over 3000 square miles, half of which is water, and has a population a little over 5000 people. I own a patch of forest there. It has gigabit fiber service. The local power company is a co-op because none of the u

This particular situation had to do with `&'static str`s baked into the program repeatedly getting compiled into `Regex`es at runtime. It wasn't possible to precompile these `Regex`es due to `serde` architectural limitations.

`Box::leak()` gets you a `&'static` at runtime. No raw pointers and no `unsafe`, but also no way to free the memory (because `&'static`). This is a technique I've used in anger: https://github.com/AS20

I'd like to add a few asterisks: Magnetic coupling removes issues with potentials _up to the dielectric breakdown voltage_. Ethernet magnetics are considered high potential components, and even the entry level options will isolate at l

Yep. There's a ton of data dependencies, where e.g. you can't begin decoding the next bit until you've finished decoding the current bit. It's all about progressive decoding so there's multiple passes over each grou

I can't speak to the general case, but there's no `libc` compatibility cruft in my app. None of my dependencies try to talk to the operating system, and the Rust I wrote in this project uses `js-sys` and `web-sys` directly. If you

Absolutely a fair criticism. As a followup, I've found that the Terraform AWS provider needs information that boto doesn't – specifically, it needs region-specific details which can only be found in the documentation. They have a
