It all began when a young man named George Hotz began to work on the PlayStation 3, trying to gain access to the machine in a way that made Sony uncomfortable. In response, Sony removed the OtherOS functionality of the PlayStation 3 in a mandatory update, and the hacking community was not happy with this decision, resulting in a sort of cold war. PS3 hackers have once again gained the upper hand: Linux has been returned to the PlayStation 3.

From the BBC:

Sony has said it will resume some services on its PlayStation Network, which was shut after the theft of personal details of about 77m users.

The term "indie game" tends to elicit images of retro-styled platformers or art games. And that's what makes the upcoming mech game Hawken from Adhesive Games so impressive. Though it has only been in development for 10 months and is being created by a relatively small team, early footage of Hawken shows visuals that rival that of many AAA releases. Studio cofounder Christopher Lalli spoke with Ars about the importance of a strong art direction and how to "cheat" to make a game look better.

From the BBC:

Millions of gamers are unable to play online as the Playstation Network remains unavailable.

Users are seeing error messages stating the network is "undergoing maintenance" or is "suspended".

In Part 1 of our series, we detailed the hardware choices and benchmarked the various GPUs and CPUs used in the HPU4Science scientific computation cluster. The cluster is built in a master-worker configuration in which the master dispatches jobs to the workers, compiles and processes the results, and handles data storage. The master is equipped with a dual Intel XEON processor, a four-SSD RAID array for short-term storage, and an array of five 2TB hard drives for archival storage. The networking is a simple Gigabit Ethernet.
