33rd Degree ConferenceKraków, 7 April, 2011

The following presentation is intended for informational purposes only.

There’s no part of it that you should consider either a guideline, viable option or production-ready set of

instructions that could solve your problem

If you use any concepts of what you see here it is entirely up to you to make sure it works for you.

AgendaThe no-brainers

PHP – the dynamic language for massesWhy would you even care?How to integrate with PHP code

Ruby – the new waveWhat’s Ruby really good at?How to integrate with Ruby code
