Does the GeForce GTX 970 have a memory allocation bug ? (update 3)
For a week or two now in our forums there have been allegations that users of the GeForce GTX 970 have a darn hard time addressing and filling the last 10% of their graphics memory. The 4 GB card seems to run into issues addressing the last 400 to 600 MB of memory, which is significant.Read more

Aliens vs. Predator Demo Patched
Unprecedented demand for Aliens vs. Predator following the release of the cross-platform demo yesterday morning brought to light matchmaking issues on the PC platform resulting in players having to wait to join games, or even not find games at all. We're pleased to say later in the day the issue was corrected and a small patch to the PC executable next time you launch it from Steam will have you finding and playing games using Quick Match as it was intended.
While this issue did not affect the Xbox 360, we are, with SEGA's assistance investigating reports of a similar nature on the PlayStation 3 and working flat out on a solution. The full game features the ability to browse for and create games but for the purposes of simplicity the demo was limited to matchmaking, alongside the ability to set up groups with friends which mitigated yesterday's issues for many. We're really sorry that this issue tainted a day in which we saw many people get hands on with AvP for the first time and we're hugely gratified by the positive feedback to the game.
Gigabyte GA-H57M-USB3 motherboard review
Gigabyte GA-H57M-USB3 motherboard review
In the wake of the Intel Clarkdale series of processors (Core i3 500 & Core i5 600 series) we have seen a lot of H55 chipset based motherboards out there. H55 is a chipset for your average mainstream entry level motherboards series, there is in fact a small step up .. it's based on the H57 chipset and will bring some more features to the table. Gigabyte was one of the first out there to ship out one of their H57 based motherboards. The Gigabyte H57 series offers a little more in the form of RAID support while it also packs a little more punch which we'll look at in this review of course. A more interesting feature on this GA-H57M-USB3 motherboard is that it also contains USB 3.0 through an onboard NEC uPD720200 host controller and very excessive display connection options like DVI, HDMI and DisplayPort.

Teens: Blogging and Twittering is for old people
Blogging, on the other hand, may become more and more of a side issue. In fact, among all the content creating activities the decline in blogging among teens and young adults is striking as it looks like the youth may be exchanging "macro-blogging" for microblogging with status updates. Since 2006 blogging among teens has dropped from 28% to 14% and among young adults (aged 18 to 29) by 24% to 15%. Some 11% of those aged 30 and over now maintain a personal blog, and 14% of them maintain a personal website.
They don't really like to use Twitter, though. While 19% of adult internet users use Twitter or similar services to post short status updates and view those of others, only.

Intel Launch Six-Core but 8-Core Chips as well
Well, if you had any doubt that multi-core processors would not be the future, think again. Loads of rumors and details already hit the web regarding both Intel's and AMD's six core processors. But as it seems now, Intel is also planning to release an 8-core processor.
That's right, eight cores which hyper-threaded show sixteen of these cute and lovely CPU load boxes in the task manager ;)
Of course the 8-core part will be introduced in the server (Xeon) segment first. It will be a 45-nm 8-core chip known as "Nehalem-EX." This actually was mentioned a year ago already, but now Intel says it has already shipped the chip to system makers, who should be shipping to customers this quarter. Unfortunately there are no other details on this SKU.
Meanwhile AMD is planning a six-core chip for single and dual-socket servers, and a dual-die version with up to 12 cores called "Magny-Cours" for two and four-socket servers, both likely under the Opteron name.
Well, let me have the 6-core version first please :)

Hitachi working on technology for 10TB HDDs
Hitachi reseach and development is working on a new storage technology that is expected to increase storage density to 2.5 terabit per square inch. That's five times the capacity of the densest hard drives of today and thus could lead towards 10 TB HDDs. To achieve this density, Hitachi is developing a thermally-assisted recording method that heats up the media with a 20nm laser beam while the magnetic head is writing the smaller bits of data.
In thermally-assisted recording, magnetic grains can be made smaller while still resisting thermal fluctuations at room temperature. As the name suggests, thermally-assisted recording uses a laser to heat up the media while the magnetic head is writing the smaller bits of data. This enables the use of media that is magnetically stable at room temperature with the very small magnetic grains required for high-density storage.
Alas there is no concrete information on when the technology will be commercially available, and even if it is expensive they will have to find a successor to perpendicular magnetic recording, which according to the same source will have a hard time reaching even 1 terabit per square inch.
