VxWorks MILS 2.0 at DSEi 2009

By Paul ParkinsonI am looking forward to Defence Systems and Equipment International (DSEi), the world's largest fully integrated international defence exhibition, which is being held in London from 8-11th September 2009. In preparation for the event, I've been setting up some Wind River VxWorks MILS 2.0 demos on a Curtiss-Wright VPX6-185 board. VxWorks MILS is Wind River's implementation of the Multiple…

Over about the last 70 years we've learned an incredible amount about the formation of planets.…

Quit bugging me: surprise NaN!

Well, I don't think we have anything to worry there.Continue…

Happy Birthday

By Mike DelimanFourty Years Ago, the product was called Multix. The inventors were directed to stop their efforts and the project was a failure. Through a chain of decisions they changed the world, created their own company, and released an operating system that's been with us ever since. Happy Birthday to UNIX, and thank you Ken Thompson and Dennis Ritchie…
