Talk video: Building Crystal in Crystal

I gave a rather spontaneous talk at the July edition of the Ruby User Group Berlin (which I organize). One of the speakers cancelled so I took it upon myself to do a replacement talk. As this was the morning of the user group I had little time. So, what do you do? I skipped my lunch break and then used the one hour I had to prepare the talk you can see embedded below. The talk is mainly about crystal, an interesting compiled programming language where the language is implemented in itself. So what better way to learn crystal than adding new functionality to crystal?

You can see me giving speaker tips, while breaking them! And then trying to do an unprepared live coding session, which fails (duuuhh surprise!). It was good fun either way, many people enjoyed the talk. Also here is the correct implementation of drop_while in crystal.

If you are interested, the other talks from the RUG::B are also online on vimeo. You can learn about Enumerator, Smalltalk and then lots of things during the lightning talks!


Video: Shoes talk at JRubyConf 2013

Finally the video of my talk at JRubyConf 2013 in Berlin is online. It was my first full length talk at a conference, I gave it almost a year ago – some difficulties with the video material and getting it online caused this delay. Nonetheless it is finally here! The talk was titled “Shoes – the Ruby Way to GUI applications” and now  you can go ahead and watch it or you can watch all the other amazing talks.

While that is a bit old, some of the information isn’t up to date anymore. Most importantly about what still needs to be implemented as we made tremendous progress so far. We have a preview release and are happily looking into the future 🙂
