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.
Cisco announced that they will aquire jabber Inc. Jabber which was the protocol name before it was adopted by the IETF as XMPP (extensible Messaging and Presence Protocol), is an open XML technology for real-time communication. Due to it’s open nature you find different (and many OSS) implementations for various clients and servers. I follow from time to time the progress of ejabberd, but it really depends what you have already in your environment established, so it worthwhile to take a look at metajacks article and the answers. the statement about being a memory hog seems to be much better with the recent versions. a worthwhile read about mcroblogging integration is again by Jack Moffit
impressive numbers demonstrated by Tervela, especially if you look at the latency achieved. Wonder which companies have them on the watchlist.
The entry page to the conference proceedings. If you’re interested in net measurement areas, it’s wortwhlie to have a look. Thorsten just send me the link to ufsdump. good papers, even I have some things to add about this. But unfortnunatly I have to postpone this. as a remark for my self, anonymous mem, dstat.
Take a look at the a presentation by Bob Metcalfe where ethernet its heading to from his perspective, the convergence between SONET and ethernet, the role of embedded devices and more about alien wavelength, missing mid span compatability. presented with a nice sense of humour
