Problem: My Node.js processes (drones on Nodejitsu) are repeatedly growing in memory until they crash and get restarted. They are multiple processes responding to websockets connections over socket.io, using socket.io's Redis store to broker messages across connections and broadcast messages.

Conclusion: that socket.io's Redis store's memory usage likely either grows indefinitely, or is just way too high. We also isolated semi-frequent reconnects to the redis client on the part of each node.js process, though this looks unrelated to the overall memory problem.

Possibly related: socketio/socket.io#1040 socketio/socket.io#463

One of my favorite past times is to look at the notebooks of famous scientists. Da Vinci's notebook is well known, but there plenty others. Worshipping Da Vinci like no other, I bought a Think/Create/Record journal, used it mostly to keep jot down random thoughts and take notes. This was great in the beginning, but the conformity of lines drove me nuts. Only moleskines made blank notebooks, so I had to buy one.

At the same time I started a freelance project. The project itself is irrelevant, but suffice to say it was very complex and spanned several months. It seemed like a perfect opportunity to use the moleskine. Looking back, all my entries fell under few categories:

• Todo
• Question
• Thought
• Bug
• Feature
