For me, it started Wednesday with the Python Language Summit, an at-least annual, sometimes biannual get together of the developers of several major Python implementations, including CPython (the reference interpreter), PyPy, Jython and IronPython. Even with a full day, there were still a lot of interesting topics we didn’t get to and will be thrashing out on the mailing lists as usual. However, good progress was made on a few of the more controversial items, and there are definitely exciting developments in store for Python 3.4 (due in early 2014, probably shortly after PyCon in Montreal if past history is anything to go by).
Thursday was a real eye-opener for me. While I did have to duck out at one point for a meeting with a couple of the other CPython developers, I spent most of it helping out at the second of the Young Coders tutorials run by Katie Cunningham and Barbara Shaurette. These tutorials were conducted using Raspberry Pis with rented peripherals, and the kids attending received both the Pi they were using as well as a couple of introductory programming books.
