I disagree with this blogpost in its entirety. Lockfiles are neither unnecessary, nor are they complicated. The argument presented against lockfiles boils down to a misrepresentation. I also dislike the presentation using the godawful yellow color and the stupid websocket gadget in the footer.

The entire point of lockfiles is to let the user decide when the version resolution algorithm should execute and when it shouldn't. That's all they do and they do it exactly as promised.

OMG is it full of yellow. And there I was wondering how one might manage a modem or a mailqueue without a lock file: these are not your father's lockfiles[1]
