kahunak writes to alert us that GIMPS has announced that the 45th and 46th Mersenne primes have been confirmed. The EFF's $100,000 award, for the first prime over 10 million digits in length, will probably be claimed. (We discussed no. 45 when it was announced.)

pfleming alerts us to developments in Arizona on a subject we have frequently discussed (e.g. FL, MN, NJ): efforts in DUI cases to obtain source code to devices that analyze blood alcohol levels. On Friday a Pima County Superior Court judge ruled that the software that powers the Intoxilyzer 8000 must be revealed to defense lawyers. "Defense attorneys representing more than 20 people arrested on felony DUI charges agreed to consolidate their cases into one and to argue it before [Judge] Bernini ... The source codes are crucial because the Intoxilyzer 8000 sometimes gives 'weird' or inexplicable results ... Six other states have been battling CMI [maker of the Intoxilyzer] over the source code — Minnesota, Florida, Louisiana, Massachusetts, Tennessee and New Jersey... CMI has currently racked up over $1.2 million in fines in a civil contempt order for not disclosing the source code in Florida."

Gamasutra sat down with Jonathan Blow, creator of the successful independent game Braid. He talks about going through the three-year-plus development cycle as a one-man team, and how his concept of the game changed as he worked on it. He also discusses what he feels is the difference between "natural rewards" and "artificial rewards." "... for the most part, when you're playing Tetris, you're enjoying it because you enjoy fitting the blocks together. Whereas when you play World of Warcraft — and what I'm about to say is a generalization, since different players enjoy different things, obviously — a lot of the appeal of playing World of Warcraft is not in the core gameplay mechanic, because it's boring, a lot of the time. ... I think what keeps them in there is, at first, the level ding, because it's very addictive to get that. 'Okay, I've got more gold. Whatever.' And eventually, they've made this huge time investment and they've got a character there and they know what that level ding feels like and the next one is pretty far off, but they can get there! And it's not any better, because this is like number 67. It's got to be better than 66!"

An anonymous reader writes "Chrome is open source, and there's clearly still some work to be done on it. In this article, Neil McAllister decided to take a peek under Chrome's hood and view it through the eyes of the developers who will improve and maintain it in the coming years. It seems Google's open source browser currently has much to offer prospective hackers — provided they use Windows. Quoting: 'The Chromium site explains how to download the source code for Linux, Mac OS X, or Windows. Unfortunately, if you're eagerly awaiting a Mac version of Chrome, you shouldn't hold your breath. As the Mac OS X area of the Chromium developer site explains, "Right now, the Mac build is a work in progress that is much closer to the start than the finish." In fact, according to the latest status report, the Chrome developers have yet to get even the browser core running under Mac OS X. Rendering actual Web pages is still a long way off, to say nothing of a usable Aqua GUI. Then again, the Linux version is in arguably even worse shape.'"

holden writes "According to a blog post, AideRSS has moved from closed to open beta. I've been using AideRSS over the past few weeks to filter my RSS feeds (including Slashdot and Reddit) and I've been quite impressed. They talk a bit about how the filtering system works, which apparently tracks a mixture of things, from pick-up in other blogs, to some clustering technology."
