Hi there.

We are Dangerous Techniques Limited.
We build things on the Internet.

The things we build are generally web applications. We prefer to build using Ruby on Rails and JavaScript and run production systems on Ubuntu Linux, but we're flexible and have experience in lots of other technology too.

If you've got a project that you need some help with, we'd love to talk to you.


We like to write about the things we learn, when we can:

  • Mobile Device Web Site Testing? Try Dynamic DNS — How to use a dynamic DNS service to provide a consistent hostname for mobile devices to access your development machine over the local network. We give a worked example using Ubuntu Linux, but the general approach could be used on other systems too.
