HotHardware have a liquid cooler lineup. The kits we're looking at today are a far cry from the water coolers enthusiasts have been building for years. DIY water coolers typically involve separate reservoirs and external pumps. The systems we've tested contain significantly less fluid and use small pumps directly integrated into the cooling block. Integrated all-in-one kits may not offer the theoretical performance of a high-end home-built system, but they're vastly easier to install and require virtually no maintenance.

New Zealand seismic stations recorded a strange event recently - a Foo Fighters concert. Two seismic stations in the Auckland GeoNet seismic network recorded the ground literally rocking to the Foo Fighters gig at Western Springs on Tuesday night. The Herne Bay -HBAZ and Eden Park -EPAZ (with IESE-Auckland Uni) stations are 1.5 and 2km from Western Springs respectively and recorded a strong low frequency signal associated with the Foo Fighters gig.

Google's Galaxy Nexus phone is now officially available in Australia, with info here, here and here. Telstra however is not the first company to offer the Nexus in Australia. Online retailers Kogan and Mobicity already have been shipping the Nexus, having sourced their stock independently of Samsung Australia. Both began taking orders for the device last month. Discussion continues in this long thread.

There's a new supercomputer which uses flash memory instead of arrays of hard drives. Naturally, it's named "Gordon". More importantly, Gordon is now at the top in terms of how many I/O (input/output) operations it can do per second, which is a critical measure for doing data-intensive computing, such as sifting through huge datasets just to find a sliver of meaningful information. In recent validation tests, Gordon achieved an unprecedented 36 million IOPS (input/output operations per second), making it the most powerful supercomputer ever commissioned by the NSF for doing I/O and breaking the previous (2010) record of only 4.2 million IOPS.

Also enjoying some big numbers is this camera setup from MIT. We have built an imaging solution that allows us to visualize propagation of light. The effective exposure time of each frame is two trillionths of a second and the resultant visualization depicts the movement of light at roughly half a trillion frames per second. Direct recording of reflected or scattered light at such a frame rate with sufficient brightness is nearly impossible. We use an indirect 'stroboscopic' method that records millions of repeated measurements by careful scanning in time and viewpoints. Then we rearrange the data to create a 'movie' of a nanosecond long event.

HP meanwhile explain the limits of batteries. So, with venture capital and the other usual suspects turning their attention to, among other things, batteries, a peanut-sized power pack will soon run your car and permanently energize your tablet. Right? Wrong. Badly wrong. While there's a lot of progress to make, the physical limits are clear.

An Austrian man has asked Facebook for all the info they have on him, and got back more than he expected, thanks OhSmeg. After a wait, the 24 year-old law student got what he was seeking: a CD with all his data stored on it - 1,222 files in all. The collection of PDF format documents was roughly the length Leo Tolstoy's War and Peace but told a more mundane story: a record of Schrems' years-long relationship with the world's largest social network.

HWSecrets want to get you up to speed on the status of PCI-E 3.0. So it is no surprise that when PCI-E Gen 3 was announced, it caught the eye of enthusiasts who have an insatiable demand for speed. At eight Giga Transfers per second (8 GT/s) bit rate, the bandwidth was doubled for PCI-E 3.0, making it the natural evolution from the long-in-the-tooth 2.0 standard. It also became a race for marketing departments to see who could implement this technology first as a way to grab this high-end, influential market.
