A couple of months ago, Opscode came out with a bunch of announcements, one of them being that they are going to support the Open Source Chef in addition to their own platform. I'd love to see more companies do this formally.

I won't lie, I'm a bit of a Gene Kim fanboy. David Nalley suggested, actually sort of insisted, that I read The Phoenix Project almost immediately after it came out. This turned out to be a Good Thing™.
In the last post I talked about our need for some improved testing tools, our choice of Spock as something to spike, and how mocking looks in Spock. As that blog got rather long, I saved the next installment for a separate post. Today I want to look at stubbing.

For years now, I’ve almost always had a server running at home. First it was an old desktop computer and then it was a QNAP NAS. The problem with the QNAP is that it is not fast at all and not as flexible as I would like it to be.
A little while back I wrote about "hacking yourself first" and detailed a bunch of different ways for developers to seek out risks in their own apps, hopefully before attackers find them first. I’m extremely enthusiastic about this approach and believe that developers need to hone cyber-offence skills...
