The CARB stack: Coffee + Angular + Rails + Bower

AngularJS is a great way to build modern web apps and this affects Rails programmers. The combination of both is an excellent choice: Build your single-page app in Angular and let it communicate via JSON with your Rails-API backend (btw, this is exactly what we did for palava). However, you might ask yourself, what the best way to combine Angular and Rails is. Should you use the JavaScript tools world (grunt, yoeman, etc.) or should you prefer the Ruby tools (thor, sprockets)?

The has_many_booleans Rails plugin

RubyBuntu -4- Make gedit better than any IDE ;)

You can, of course, use an IDE for coding – but reconsider it: After hours of initialization, it tries to do everything for you… Somewhere in the never ending menu jungle… And you need to click all the time… Stop! Focus on the gist! You want to write code!


RubyBuntu -1- Installing Ruby (and Rails) on ubuntu

Installing Ruby/Rails on ubuntu is not hard, but some little obstacles might be confusing.


Organise your code comments with rake notes:todo!

Lots of IDEs (e.g. Netbeans) and some editors (e.g. gedit with plugins) have a nice feature: They show comments, which start with something like TODO or FIXME. Those annotations are quickly written and they make it harder to forget some things you wanted to (or have to) do.

I have just discovered that Rails has this feature already built-in!
