Hi! Working on my project I faced a problem: I needed to concatenated audio snippets(local or remote) to get final audio output and to play it to customer. I've decided to make the solution flexible and reusable, and as result I got something similar to ERB, based on ruby DSL: https://github.com/TMXCredit/audio_glue

Thanks!

Rails validation with Themis

greyblake — Wed, 21 Aug 2013 07:14:39 +0800

We've open sourced Themis: https://github.com/TMXCredit/themis It's a library which makes validation in rails a little bit more flexible(e.g. you need to apply different validations on a model graph depending on context).

And here is article how to use it: http://greyblake.com/blog/2013/08/19/validation-in-rails-with-themis/ Also I showed in article alternative approaches to solve similar problems.

Thanks, and sorry for English. One day I'll speak Chinese, I promise! :-)
