River (getriver.com): Keep a programming journal.
View pictures.markdown

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

Problem solving high memory usage with node.js, websockets, socket.io, and redis.
View problem-solving.md

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: https://github.com/LearnBoost/socket.io/issues/1040 https://github.com/LearnBoost/socket.io/issues/463

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

# you can make a text file of request times (in ms, one number per line) and import it here, or you can use a probability distribution to simulate request times (see below where setting req_durations_in_ms)
# rq = read.table("~/Downloads/request_times.txt", header=FALSE)$V1
# argument notes:
# parallel_router_count is only relevant if router_mode is set to "intelligent"
# choice_of_two, power_of_two, and unicorn_workers_per_dyno are only relevant if router_mode is set to "naive"
# you can only select one of choice_of_two, power_of_two, and unicorn_workers_per_dyno

Facebook Perl source code from 2005. When browsing around thefacebook.com in 2005 the server spit out some server-side source code rather than running it. I believe this was for their old graph feature that let you visualize the graph between all your friends. The filename is `mygraph.svgz` and contains some gems such as a commented out "zuck" d…
