blboo writes: Remember the Contiki operating system? A few years back it was used to run web servers and web browsers on really old home computers such as the Commodore 64 and the 8-bit Atari. Today Contiki has grown up and moved from being a cute hobby project to a serious embedded operating system used in research into networked embedded systems and wireless sensor networks. In fact, it has matured so much that Adam Dunkels, the author of Contiki, earlier today announced his PhD thesis on Contiki and its components; protothreads and the uIP embedded TCP/IP stack. It is an interesting direction for a niche hobby OS to take and probably quite different from what people expected Contiki to become when it first was released.
