I confess I read it as Compact Disk. This made me curious enough to read the post, which I probably wouldn't have bothered to do otherwise. It was interesting though.

CI yes, CD no - in my mind CD is pretty much fixed to compact disc for eternity.

When I first read the title I thought "oh, Yahoo must have had some cool automatic system to burn CDs that is probably so old and pointless that they are opensourcing it now as part of their mothballing". I was fairly disappointed to see it's Yet Another CI Tool.

Haha, I had exactly this...

Not entirely obvious to me. I mean, we are talking about Yahoo! and I remember when I used to get those AOL CDs in the mail on a weekly basis.

When I read "CI/CD", I think "Corporate Identity / Corporate Design", which is just as confusing, if not more so... :-?

Obvious to me too, but people doing CI, even a basic implementation like compiling, are still a minority of developers.
