## Crate of the Week

<!-- COTW goes here -->
This week's crate is [float8](https://crates.io/crates/float8), an 8-bit float implementation.

llogiq is still pleased with his choice, but increasingly unhappy about the lack of suggestions.

[Please submit your suggestions and votes for next week][submit_crate]!

# Quote of the Week

<!-- QOTW goes here -->
> I'm the wrong side of 45. I have zero interest in wasting any time that I might have left writing C from scratch. Writing Rust is pure joy. I can go from an idea to a working, tested, robust, published and packaged implementation in the time it would take me to even begin the first few lines of a C version. The tooling is beautiful, makes programming fun, and the end result usually outperforms the equivalent C. Once it builds I know it will run perfectly on all of the platforms I care about, and I don't have to go around manually testing on them to find all of the various platform and compiler quirks that will break it.
