Jonathan Corbet presented a informative presentation about the recent linux kernel work. It was held at the 11′th realtime Linux workshop, and offers some insides and statements not always presented in the normal press, like from 2.6.27 -> 2.6.31++ rough timeframe (October 9, 2008 to September 18, 2009) 48,000 changesets was merged by 2,500 developers and 400 employers. This result is that the kernel grew by 2.5 million lines, or better 140 changesets merged per day and 7267 lines of code added every day. But he also depicts some major functionality added by each version and why it’s needed. paired with some funny pictures a nice walk through. The other papers from the conference are also a good read, take a look at them by yourself

TUD presented EASY-A and achieved a record in transmission. They claim its very energy efficient in that the emitter and receiver only need one bit resolution for transmission. The signals use 4GHz bandwith and it took 6.4 seconds for 8 Gigabyte.
one have to admit, that they (still) used cable for transmission, but they’ve designed/created the demonstrator using the concept of their 60 GHz wireless transmission. They estimate about 5 years before this could be used in commercial products.
