It's an open source project either:

What I do is, essentially, the following: every day at around 0-1 am (before I go to sleep) I set a timer so that it would fire at 7-8 pm (that's when I would get home). This allows me to force myself from browsing unnecessary sites (facebook, twitter, HN, reddit etc.) that would otherwise distract me from doing meaningful work.

As for the other devices, not long ago I would have twitter, facebook, VK, and a few others social media apps on my iPhone. I deleted everything except twitter which I check rarely (<= 10m a day). Deleting the facebook app contributed greatly to my smartphone's battery life either.

which was inspired by this paper:

which google made available for all in form of it's cloud datastore:

"We believe it is better to have application programmers deal with performance problems due to overuse of transactions as bottlenecks arise, rather than always coding around the lack of transactions." [1]
