• "As serious intellectuals often do, we spent hours discussing these questions, what data we would want to collect to answer them, and even how we might go about collecting it. It sounded like a fun project, so I wrote a program that takes video captures of our Mario Kart 64 sessions and picks out when each race starts, which character is in each box on the screen, the rank of each player as the race progresses, and finally when the race finishes. Then I built a web client that lets us upload videos, record who played which character in each race, and browse the aggregated stats. The result is called Kartlytics, and now contains videos of over 230 races from over the last year and change." Yes, it's a plug for manta, but it's also a nifty piece of engineering.
  • "Termshows are purely text based. This makes them ideal for demoing instructions (as the user can copy-paste), making fail-safe "live-coding" sessions (plain text is very scalable), and sharing all your l33t terminal hacks." Really lovely: record terminal activity, upload it to a URL, share it with others, dead simple. And the client playback is all javascript. Lovely.
  • "Python has one. Ruby has one. Clojure has one. Now PHP has one too. Boris is PHP's missing REPL (read-eval-print loop), allowing developers to experiment with PHP code in the terminal in an interactive manner. If you make a mistake, it doesn't matter, Boris will report the error and stand to attention for further input." I use PHP increasingly little, but the lack of a REPL drives me insane. This looks… useful, at the very least.

  • "jq is like sed for JSON data – you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text." Sounds super-useful.
