Multiple readers have written to let us know that an experiment at the upcoming Hackers on Planet Earth (HOPE) conference will use RFID to track the movements of at least 1,500 registrants for the duration of the conference. Those movements will be transmitted onto screens which "show in real-time where people go, with whom they associate, for how long and how often." The system will also be used for games which involve manipulation of the available data. Meanwhile, researchers at the Georgia Institute of Technology have developed a method for testing large quantities of RFID tags, which may serve to greatly speed distribution.

Apro+im points out a NYTimes report which states that Microsoft and the OLPC project have officially agreed to put Windows XP on the XO laptop. While Microsoft has been working toward this for some time, analysts began to think a deal was more likely after Walter Bender resigned from the project and was replaced by Charles Kane. Former OLPC security developer Ivan Krstic had a lot to say about Windows on the XO as well. From the Times: "Windows will add a bit to the price of the machines, about $3, the licensing fee Microsoft charges to some developing nations under a program called Unlimited Potential. For those nations that want dual-boot models, running both Windows and Linux, the extra hardware required will add another $7 or so to the cost of the machines, Mr. Negroponte said. The project's agreement with Microsoft involves no payment by the software giant, and Microsoft will not join One Laptop Per Child's board. 'We've stayed very pure,' Mr. Negroponte said.

Anonymous writes "With the releases of Fedora 9, Hardy Heron and OpenSuSE 11 so close together, it's looking more than ever like an evolution to a common interface for major Linux distributions. Here's a compilation of screen shots and descriptions that make it appear to be the case. Would this be a good thing or a bad thing?" There are plenty of other options out there, of course, even considering only Linux distros that are based on Gnome and KDE, and plenty of wilder (or at least less common) desktops to choose from besides.
