After a group of StarCraft II beta testers reported technical difficulties following the installation of NVIDIA driver update 196.75, Blizzard tech support found that the update introduced fan control problems that were causing video cards to overheat in 3D applications. "This means every single 3D application (i.e. games) running these drivers is going to be exposed to overheating and in some extreme cases it will cause video card, motherboard and/or processor damage. If said motherboard, processor or graphic card is not under warranty, some gamers are in serious trouble playing intensive games such as Prototype, World of Warcraft, Farcry 3, Crysis and many other games with realistic graphics." NVIDIA said they were investigating the problem, took down links to the new drivers, and advised users to revert to 196.21 until the problem can be fixed.

Google announced Buzz today, as we anticipated this morning. CNET has a workmanlike description of the social-networking service, which is integrated into gmail. CNET identifies a central obstacle Buzz will have to overcome to gain traction: "The problem, however, will be the increasing backlash Google is seeing from the general public over how much data the company already controls on their online habits." Buzz is being rolled out over the next few days so some people will see a Buzz folder in their gmail, but most won't yet (this Twitter post explains how Safari users can get an early glimpse). A blog posting up at O'Reilly Answers points out some of the distinguishing characteristics of Google Buzz — one interesting one being its ability to post an update either publicly or privately, at the user's option. This design choice places it between the public-by-default Twitter and the private-by-default Facebook. Lauren Weinstein sounds a note of caution about the inherent privacy risks of Google's method of filling out initial friend profiles by automatic friending.

Several readers have sent word that George Hotz (a.k.a. geohot), the hacker best known for unlocking Apple's iPhone, says he has now hacked the PlayStation 3. From his blog post: "I have read/write access to the entire system memory, and HV level access to the processor. In other words, I have hacked the PS3. The rest is just software. And reversing. I have a lot of reversing ahead of me, as I now have dumps of LV0 and LV1. I've also dumped the NAND without removing it or a modchip. 3 years, 2 months, 11 days...that's a pretty secure system. ... As far as the exploit goes, I'm not revealing it yet. The theory isn't really patchable, but they can make implementations much harder. Also, for obvious reasons I can't post dumps. I'm hoping to find the decryption keys and post them, but they may be embedded in hardware. Hopefully keys are setup like the iPhone's KBAG."

juicegg writes "Wives of Rockstar Games employees in San Diego recently published an open letter on their Gamasutra blog. The authors say that Rockstar employees are seriously strained by unending crunch periods of 12-hour work days and 6-day weeks. High levels of stress are leading to serious psychological and physical problems for some of the employees. They charge that studio management uses arbitrary, deceptive and manipulative practices to get employees to work more unpaid overtime hours at greater intensity — despite over $1 billion in Grand Theft Auto revenue. Among the blog comments, some current and past Rockstar employees are confirming problems with the studio. 'Ex Rocker' writes: 'What makes R* crunch periods different then any other studio is that they tell you the game has to be finished in 6 months, so let's start our final push to get this awesome game out there! 6 months turns into 1 year, 1 year turns into 2.' Other comments reveal worker hopelessness and general mismanagement at the San Diego studio. This turmoil is affecting development on upcoming games as well." Read on for responses from Rockstar itself and other members of the industry.
