DARwIn OP Open Source Robots

I am very intereted in the humanoid robots but really worried about the situation in the movie"I, Robot" would come true. I realise I might have think too much.

DARwIn OP is the New open source humanoid robot released in the United States Institute of Electrical and Electronics Engineers (IEEE) 2010 this week,it is 18 inches high and weighs 6 pounds.
DARwIn-OP is the fruit of collaboration among Dennis Hongs team of Virginia Tech, University of Pennsylvania, Purdue University and the Korean Robotis company. The Invention Team announced that both hardware and software of DARwIn-OP are open source, you can customize various parts of the robot body,select the desired parts, then assemble them.

10 pcs DARwIn-OP will be produced this week for research in the university, and it is sold at $12000.

An Open Source App Rietveld Code Review Tool

Posted by Guido van Rossum, Software Engineer

My first project as a Google engineer was an internal web app for code review. According to Wikipedia, code review is "systematic examination (often as peer review) of computer source code intended to find and fix mistakes overlooked in the initial development phase, improving both the overall quality of software and the developers skills." Not an exciting topic, perhaps, but the internal web app, which I code-named Mondrian after one of my favorite Dutch painters, was an overnight success among Google engineers (who evidently value software quality and skills development :-). I even gave a public presentation about it: you can watch the video on YouTube.

Ive always hoped that we could release Mondrian as open source, but so far it hasnt happened: due to its popularity inside Google, it became more and more tied to proprietary Google infrastructure like Bigtable, and it remained limited to Perforce, the commercial revision control system most used at Google.

Fortunately, now that I work on the Google App Engine team, Ive been able to write a new web app that incorporates many ideas (and even some code!) from Mondrian, and release it as open source. The Python open source community has been trying out Rietveld for the past few days, and has already been using it to do code reviews for Python (as well as providing valuable feedback in the form of bug reports and feature requests). Of course, the tool is not language-specific: you can use it for code reviews for any language!

To learn more about Rietveld, try it out, or take a look at the code, check out the article on Google Code!
