I recently bought a Wipy development board to try MicroPython as a friend of mine is a big fan, and I whet a TI CC3200 (ARM Cortex-M4+wifi) development board even if I prefer to develop it in C.

Here is just a snippet allowing to ground or set to 3.3V GP4 in order to connect to home WLAN or set the card as an access point. Great for on-the-go development!

I lost a few couples of minutes trying to figure out where and how rss2mail is storing its configuration files, as I did not find in the documentation.

I recently bought an SSD for my old Apple computer. I updated the system from Snow Leopard to Yosemite as some applications required a newer system.

I recently discussed with some friends about sensors to record jump heights and hang time when kitesurfing. They are really expensive and requires to wear a phone in a waterproof case.
