I just posted on the Harry’s engingeering blog about a mock gateway for Authorize.net payment APIs for use in Rspec unit tests and development Rails environments. We found that this sped up our test run at least 2X compared to using the Authorized.net sandbox server.
I just released (as part of my work at Harry’s) an autoscaler for Heroku that uses Google Analytics realtime data to scale a Heroku app up or down.
More info in my post on the Harry’s engineering blog.
Having finished my PhD, Alex and I have moved to South Africa for a year to volunteer with a fantastic organization that supports community-based care of HIV/AIDS affected children. I’m intending to keep Ultrahigh around for posting geeky stuff, but we have also started a new blog about our travels and work in Africa. It’s called Live Free or Braai Hard and you can find it at http://africa.potatoriot.com.
