The nalgebra crate provides a wide set of mathematical primitives for linear algebra, computer physics, graphic engines etc. I'm not going to dive deep into the underlying math, there are a lot of tutorials and courses, some of them specifically targeted at the programmers. My goal for today is just a brief showcase of what we can do in Rust with nalgebra.

Writing the Postgres article reminded me of one more cool thing in PostgreSQL - native support for the UUID type. The popular web framework Django will soon get a UUID field, Rails already support it. So what's the big deal?

The image crate is a library under development (well, not unlike the rest of the Rust ecosystem before 1.0) to read, manipulate and write images. It is part of the effort to develop an open source game engine in pure Rust - Piston, but of course the image crate can be used on its own.

At the moment image supports reading and writing JPG and PNG images, while a few other formats are read-only (GIF, TIFF, WEBP).

Yes, I'm biased. PostgreSQL is my favorite SQL database and the upcoming 9.4 release makes me even more excited. There is already a pure Rust driver for PostgreSQL - the postgres crate which will be the subject of today's article.

τ (tau) is one of the most important mathematical constants (if not the most important), relating circle's circumference to it's radius. See the tau manifesto for the long explanation if you're still an unbeliever. Can we use it in Rust? Of course, there's a crate for that!
