Contiki released their newest version of the Contiki OS, 2.2.3. Contiki is an open source OS that is generally used to run very portable, networked embedded systems and wireless sensor networks. The typical RAM and ROM footprint of a Contiki configuration is two kilobytes and 40 kilobytes, respectively; if that’s not ‘highly portable,’ I don’t know what is. New features in 2.2.3 include checkpointing, which stores the complete execution state of a system in a single file; per-packet power profiling, which allows fine-grained breakdown of power consumption; announcements, which make neighbor and route announcements protocol-independent; and Deluge, a bulk data dissemination protocol. New ports to the Meshnetics ZigBit and Sentilla JCreate modules were also released.
