I’ll probably be posting from some of the sessions as I go. Long posts will be on this blog, short things and ‘overheards’ will be on my Twitter.
If you’re here, […]
As a follow-up to yesterday’s post about Matt Williams’s presentation on Ruby and Arduino, here are some videos, slides, and notes from the ORUG site.
You absolutely must check this out. The field of robotics is going to play such a massive role in all of our lives over the next few years, and this is […]
Just got back from this month’s ORUG, where Matthew Williams gave a presentation on using Ruby to control an Arduino. Matt is a very natural speaker, and the presentation was great. He even demoed a bartending robot he built, which should be featured on Make very soon.
I took notes during the presentation, and they are […]
