Very good talk, incorporated the idea of supplementing PHP for all of those non-web tasks.
Hopefully Matej will now be less affraid of English to speak more often (he had really interesting subjects up to now)!
One small suggestion: bit less text on the slides and break those long bullet point lists into multiple slides (or remove some of them).
Nice, short and to the point. Makes a good case for trying out Go. Matej has good speaking skills and a very decent grasp of English.
My only complaint would be the slides. Sometimes they contain exact sentences being spoken. It might be better to have less text on slides. Also, the white on black color scheme has poor visibility.
Really good talk in general. Surprisingly,a noob speaker (especially doing it in English) with lot of confidence and no visible nervousness or stage fright.
Good overview of how they moved from 5.3 to 5.6, covering why and how they did it and why should we all migrate to 5.6.
While it became obvious after Q&A that there is no major code changing/overhauling needed it would be really great to put it into the presentation itself.
