rsync (Everyone seems to like -z, but it is much slower for me)

Advanced SCSS

Or, 16 cool things you may not have known your stylesheets could do. I'd rather have kept it to a nice round number like 10, but they just kept coming. Sorry.

I've been using SCSS/SASS for most of my styling work since 2009, and I'm a huge fan of Compass (by the great @chriseppstein). It really helped many of us through the darkest cross-browser crap. Even though browsers are increasingly playing nice with CSS, another problem has become very topical: managing the complexity in stylesheets as our in-browser apps get larger and larger. SCSS is an indispensable tool for dealing with this.

This isn't an introduction to the language by a long shot; many things probably won't make sense unless you have some SCSS under your belt already. That said, if you're not yet comfy with the basics, check out the aweso

This is how I configured the deploy of my rails apps to AWS Elastic Beanstalk through CircleCI 1.0.

If you are using the Circle CI 2.0, take a look at this article from ryansimms

On Project Settings > Environment Variables add this keys:

• AWS_ACCESS_KEY_ID
• AWS_SECRET_ACCESS_KEY
  The aws user must have the right permissions. This can be hard, maybe, this can help you.
