In this interesting ELC video, Grant Likely, a Linux kernel engineer and maintainer of the Linux Device Tree, describes his journey into embedded hardware. Sometimes the best tutorials come not from experts, but from proficient newcomers who are up to date on the latest entry-level technologies and can remember what it’s like to be a […]

Okay, this program is free (beer), but not Free (speech). I wouldn't normally include a freeware application in a "Non-Linux FOSS" piece, because quite frankly, it isn't FOSS. But, I decided to break the rules a bit here because I realized how often I use a freeware program when I'm on OS X that I couldn't imagine doing without.

Looking back at 10 years of Hadoop, project co-founder and Cloudera Chief Architect Doug Cutting can see two primary factors in the success of open source big data technology: a heap of luck and the Apache Foundation’s unique support. Cutting delivered a keynote at the Apache Big Data conference in Vancouver in May. In that talk, he said Hadoop was the right technology at the right time, but the reason it was able to capitalize on that position was the work from the Apache community.
