Converter NOW: Unit Converter (version 4.2.0): A simple, immediate and fast unit converter!

Or build it from source code!

Progressive web app (link)

I wrote and mantain Converter NOW (https://github.com/ferraridamiano/ConverterNOW). It is a multiplatform (Android, Linux, Windows and Web) unit and currency converter. It is built to be easy to use, it doesn't require any special permission (just internet to update the exchange rates) and it doesn't contain any form of tracking. The android version is available to both play store and f-droid.

Few days ago I released the first stable relase of units_converter. It is a unit converter package written in dart that has 100% test coverage (this is very important with this kind of libraries, it does one thing and it has to do it well). It also has a permissive license. This package is used in Converter NOW, a multiplatform (android, web, windows, linux) unit converter app written in Flutter.

Obviously as an interpreted language, it's never going to be as fast as something like C, Rust, or Go. Traditionally the ruby maintainers have not designed or optimized for pure speed, but that is changing, and the language is definitely faster these days compared to a decade ago.

If you like the ruby syntax/language but want the speed of a compiled language, it's also worth checking out Crystal[^1]. It's mostly ruby-like in syntax, style, and developer ergonomics.[^2] Although it's an entirely different language. Also a tiny community.

Crystal is a nice language that's not only simple to read and write but performs very well too. And the documentation is amazing as well.

Ruby is a super fun scripting language. I much prefer it to python when I need something with a little more "ooomph" than bash. It's just...nice...to write in. Ruby performance has come a long way in the last decade as well. There's libraries for pretty much everything.

My modern programming toolkit is basically golang + ruby + bash and I am never left wanting.

I do find Crystal (https://crystal-lang.org/) really interesting and am hoping it has its own "ruby on rails" moment that helps the language reach a tipping point in popularity. All the beauty of ruby with all of the speed of Go (and then some, it often compares favorably to languages like rust in benchmarks).
