It's probably those same engineers that use Dropbox instead of getting an FTP account, mounting it locally with curlftpfs, and then using SVN or CVS on the mounted filesystem.
This still boils down to calories in/out though. Metabolism goes under the 'out' column. It fluctuates, sure, but it's just as much an 'out' variable as exercise is.
I implemented something like this on a site visited almost exclusively by developers, assuming that developers must have amongst the highest adblock usage, and that my real visitor numbers according to GA would be much higher.
I saw a boost of about 7-8%. Remember, most adblockers (like Adblock Plus) don't block Google Analytics. uBlock and Ghostery are probably the 2 main GA adblockers, but as a % of adblockers as a whole they're not that large.
I'm convinced the problem with these keyboards isn't always debris under the keys. I've noticed it's often E and R, the keys right above the heatpipe system, which suggests that heat could be warping or damaging the contacts. This is even worse.
I'd love to get something other than a MacBook, but the trackpad compensates for every other flaw. It's also nice that there's no air vent on the bottom.
MacBook Air, the new MacBook for Pros.
