Wind River Linux and the Yocto Project…Sowing the seeds of change

By Davide Ricci The year was 1998, I was walking through the aisles of a book store on campus at the Politecnico of Milano and a box of software caught my eye. It looked unconventional, sort of "homemade" and on its cover was an image of a man with a red hat. It was Red Hat 5.2, and the box…

Testing Manycore Scaling with Simics

By Jakob Engblom A few years ago, I did a Simics demo where I tested the scalability of a multithreaded program as the target hardware went from two to four to eight cores. Unfortunately, I could not take it beyond that point, since the hardware platform that I used simply did not allow for more than eight cores. Now, with…

The Role of Tools in Improving Embedded Software Security / Part 2: Security Improvement and the Software Development Lifecycle

By Bill Graham In many of my previous posts, I’ve discussed Wind River's 5+1 step improvement framework for embedded device security. By design, it’s meant to complement the software development lifecycle (SDLC) that our customers are using – the stages or phases how they define them and the processes they follow. It’s important for a discussion on tools to put them in…

MSL: How Big Is It?

By Mike Deliman I’ve been asked here and there “Just how big is this MSL thing?” It’s a question I can give several answers to, depending on what the asker means.  In physical terms, you could ride on it.  Here is a good example…in this photo of a worker and MSL, you can see the cruise shell is large enough to…

The Yocto Project: What It Is and What It Isn’t

What exactly is the Yocto Project? Is it a Linux distribution?  How…

All Your Mars are Belong to US!

By Mike Deliman It's time to celebrate. We have returned to Mars with the most complex roving robotic laboratory ever sent to another planet. We have demonstrated and proved the Sky Crane concept, which opens doors onto other worlds that we have never had before. We can successfully deliver 1 metric ton to the surface of Mars.This is an achievement…

Complexity

By Mike Deliman This afternoon I watched the press conferences for Mars Science Laboratory “Curiosity” that were hosted by NASA/JPL from Pasadena, Ca.  These conferences were broadcast over NASA-TV, both on the cable/satellite channels and over the web.  If you haven’t seen the Seven Minutes Video I encourage you to watch it. Various scientists, directors and managers of the project…
