The trouble is, many developers have invested themselves in one technology or another (PHP, Java, Cold Fusion, ASP…) prior to the breakout of Ruby on Rails. Switching programming languages is not something most developers want to do.
We have been primarily a PHP shop since 1999. So, I was delighted to come across PHP on Trax recently. Turns out one of the principal developers in a FreshBooks customer (he wrote us a note shortly after we could Trax).
Check it out, and if you can, spread the word and/or get involved with building up the technology – it’s open source.
