Nvidia DX11 Ocean technology demo
The demo shows a real-time simulated ocean under twilight lighting condition. To obtain good looking wave crests, a rather large height field has to be employed. With Microsoft's newly introduced DirectX Compute Shader we can efficiently perform FFT on GPU, thus greatly improving the performance and image quality.
The water surface is mainly modeled after Jerry Tessendorf's statistic method described in the paper "Simulating Ocean Water", which is one of the most popular techniques used for water effect in todays games. Although the algorithm itself is capable of producing visually impressive result from a presumed statistic model (Phillips spectrum), previous implementations are often limited to a relatively small height field, e.g. 64x64 or 128x128, due to the slow FFT code path on CPU. For example, the demo shown here executes three 512x512 Fourier transforms on a per frame basis. On a GTX280, the transforms can be finished within 2 milliseconds.

ESWC is dead, company enters liquidation
The result was that Games-Services has now entered liquidation, in other words ceased all business operation by using its assets to discharge its liabilities (its debts). Matthieu Dallon sent out a release in March stating that the ESWC organisers were "facing a serious cash flow crisis."
Games-Services made it official after posting an announcement earlier today on their website confirming the cease of all activities.
"Games-Services SA ceases all activities. Its liquidation has been pronounced by the Commercial Court of Paris March 30, 2009. In consequence, all the employees and managers have been relieved from their duties and laid off April 2nd, by the adjudication.
The process of liquidation, which is starting this week, will notably organize the potential trade-in or resale of the company

ASUS Radeon HD 4890 with voltage tweak options
Aah see, now this is intresting. ASUS has introduced its overclocked Radeon HD 4890 series, the EAH4890 TOP with 900MHz core and 1GB GDDR5 memory clocked at 4000MHz, versus a 850MHz core and 3900MHz memory on the default cards.
This EAH4890 graphics cards come with Voltage Tweak technology and enables users to push the GPU voltage from 1.312V to 1.4V, and overclock the card to 950MHz core and 4600MHz memory. According to ASUS, this will result in a 15 percent performance boost in 3DMark Vantage over default Radeon HD 4890 cards.

Virus-built battery built by MIT
The new virus-produced batteries have the same energy capacity and power performance as state-of-the-art rechargeable batteries being considered to power plug-in hybrid cars, and they could also be used to power a range of personal electronic devices, said Angela Belcher, the MIT materials scientist who led the research team.
The new batteries, described in the April 2 online edition of Science, could be manufactured with a cheap and environmentally benign process: The synthesis takes place at and below room temperature and requires no harmful organic solvents, and the materials that go into the battery are non-toxic.
In a traditional lithium-ion battery, lithium ions flow between a negatively charged anode, usually graphite, and the positively charged cathode, usually cobalt oxide or lithium iron phosphate. Three years ago, an MIT team led by Belcher reported that it had engineered viruses that could build an anode by coating themselves with cobalt oxide and gold and self-assembling to form a nanowire.

Daily deals April 5 2009
It's a slow weekend news wise, so I figured to make a daily deals session. For this edition I want to focus on input devices like keyboards and mouse's.
- Wacom Bamboo Digitizing Tablet - Have you ever worked with a digitizing mouse pen ? Quite incredible, VERY precise in say photoshop and what not. Have a peek, spotted for $69.00 just have a peek really.
- Microsoft Natural Ergonomic Keyboard 4000 - A great product, very sturdy, very efficient. I have a couple of these myself. I found one for $23.99 which hinestly is a bargain as they typically sell at 4- to 50 bucks.
- Logitech G15 Keyboard - such a classis. What else needs to be said ? I found an address selling them at $69.99
- Logitech Illuminated Keyboard - classy, stylish .. Logitech = expensive though. You can pick it up for $73.24
- Razer Arctosa Silver Edition Gaming Keyboard - Gamers unite .. ehm well still, a lovely set of keys, selling at $43.42
- Logitech diNovo Edge Keyboard - probably the best looking set of keys available on the web, though the lack of numeric keys still confuse me. But what a style. The cheapest I could find was $139.90
Overclocking the Radeon HD 4890
This week the Radeon HD 4890 was released and as our reference article showed, it has a lot of overclocking potential, really it has a lot of headroom there which could results in 10% better performance on average. Typically overclocking can be managed really well through the Catalyst Control Center, however .. the control center always has certain restriction as in 'how much' you can actually overclock.
In this article we'll show you how you can overclock the easy way, with the help of Rivatuner, followed with a couple of performance results as well.

France Close To Passing Tough Anti-P2P Law
France's National Assembly (the lower house of France's Parliament) is close to passing an anti-P2P law which it was discussing for several weeks, already. This law (if passed) would punish illegal file sharers after receiving multiple warnings by cutting off their Internet access, ranging from one month up to one year.
HADOPI, the "High Authority" created by the law, would "receive and evaluate complaints made by rightsholders about online file-sharing of copyrighted works. It will then issue warnings to ISPs, which are required to pass them along to the customer account in question.""HADOPI will also maintain a blacklist, and sanctioned users will not be able to sign up for service with any Internet provider in the country during their time on the list. ISPs who refuse to promptly disconnect subscribers face a
IBM Close to Buying Sun Microsystems for 7 Billion
Apparently, the talks between International Business Machines Corporation (IBM) and Sun Microsystems, Inc., which were going on during the last few weeks, are in their finalizing stages. Reportedly, I.B.M. is offering $9.50 a share which would value Sun at close to $7 billion.
Sun is well known for its Java technology platform, the Solaris Operating System, the MySQL database management system, Sun StorageTek storage solutions, the UltraSPARC processor, and for being one of the largest sellers of servers.
There could be quite a few far-reaching consequences because of this acquisition:
"I.B.M.'s acquisition of Sun would disrupt that long partnership with Oracle. I.B.M. could also undercut Oracle by more actively promoting the free MySQL software, which has become the most popular database software with Internet companies.
Hardware inherited from Sun could present antitrust concerns. I.B.M. faces an antitrust complaint from T3 Technologies over its dominance in the mainframe market. By buying Sun, I.B.M. would gain close to total control over robotic tape storage devices used to file data on mainframes.
Sun has a sales and technology partnership with Fujitsu for the sale of Unix servers. If I.B.M. buys Sun, Fujitsu and Hewlett-Packard will be the combined company's only major competitors in the Unix market, a possible concern for regulators here and in Europe. Sun faces a patent infringement lawsuit from the storage maker NetApp and has countersued. NetApp has a sales pact with I.B.M."
As an early result, shares of I.B.M. rose more than 3 percent on Thursday, to $100.82, while Sun's shares rose more than 2 percent, to $8.21. [via New York Times]

ATI Radeon HD 4890 shipments over 50,000
It was a good hard launch for ATI yesterday. As it seems ATI has shipped over 50,000 units of its 1.36 TeraFLOPs monster, the Radeon HD 4890 graphics card. Several retailers have already sold cards to anxious fans ahead of today's launch date.
The cards themselves should sell for no more than $250 at stock speeds, although we expect prices to drop slightly in a month's time. Some partners have also said that mail-in rebates for $20 will be available.
