Submission + - Microsoft releases new OS attempt, Barrelfish (

Julie188 writes: "You've likely heard of Microsoft's next-gen operating system projects Midori and Singularity, but earlier this month researchers released a prototye for another OS, code-named Barrelfish. Barrelfish is an OS written specifically for multicore environments. It hopes to improve the performance of boxes with such chips by creating a network bus, if you will, between cores. Today such systems tend to share resources like memory. As demand increases, performance of the box decreases as shared resources don't scale well. Barrelfish instead passes messages between cores on its bus, and reportedly uses a database-like approach to keep track of the hardware available."

AMD Radeon HD 5870 Adds DX11, Multi-Monitor Gaming 195

Vigile writes "Few people will doubt that PC gaming is in need of a significant shot in the arm with the consistent encroachment of consoles and their dominating hold on developers. Today AMD is releasing the Radeon HD 5870 graphics card based on the Evergreen-series of GPUs first demonstrated in June. Besides offering best-in-class performance for a single-GPU graphics board, the new card is easily the most power efficient in terms of idle power consumption and performance per watt. Not only that, but AMD has introduced new features that could help keep PC gaming in the spotlight, including the first DirectX 11 implementation and a very impressive multi-monitor gaming technology, Eyefinity, which we discussed earlier this month. The review at PC Perspective includes the full gamut of gaming benchmarks in both single- and dual-GPU configurations as well as videos of Eyefinity running on three 30" displays."

Early Details On Courier, Microsoft's Take On a Tablet 175

rbanffy points out an article on Gizmodo about Courier, a tablet (or more accurately, a booklet) in development at Microsoft. "The dual 7-inch (or so) screens are multitouch, and designed for writing, flicking and drawing with a stylus, in addition to fingers. They're connected by a hinge that holds a single iPhone-esque home button. Statuses, like wireless signal and battery life, are displayed along the rim of one of the screens. On the back cover is a camera, and it might charge through an inductive pad, like the Palm Touchstone charging dock for Pre." A concept video shows off the ability to use the two different screens for separate purposes, like browsing the web or a photo album on the left and using the right as a notepad or workspace.

Submission + - First public sighting of Larrabee (

darien writes: "Intel has given the first public demo of Larrabee, its x86-based multi-core graphics system, at IDF in San Francisco. The demo showcased real-time ray traced reflections, but looked distinctly underwhelming compared to what's possible with current GPU technology — and no one was willing to talk about the technical details."

For those who do not feel comfortable going to the Project INDECT site here's an excerpt:

Project Description

Intelligent information system supporting observation, searching and detection for security of citizens in urban environment.

The main objectives of the INDECT project are:

  • to develop a platform for: the registration and exchange of operational data, acquisition of multimedia content, intelligent processing of all information and automatic detection of threats and recognition of abnormal behaviour or violence,
  • to develop the prototype of an integrated, network-centric system supporting the operational activities of police officers, providing techniques and tools for observation of various mobile objects,
  • to develop a new type of search engine combining direct search of images and video based on watermarked contents, and the storage of metadata in the form of digital watermarks,

The main expected results of the INDECT project are:

  • to realise a trial installation of the monitoring and surveillance system in various points of city agglomeration and demonstration of the prototype of the system with 15 node stations,
  • implementation of a distributed computer system that is capable of acquisition, storage and effective sharing on demand of the data as well as intelligent processing, construction of a family of prototypes of devices used for mobile object tracking,
  • construction of a search engine for fast detection of persons and documents based on watermarking technology and utilising comprehensive research on watermarking technology used for semantic search,
  • construction of agents assigned to continuous and automatic monitoring of public resources such as: web sites, discussion forums, UseNet groups, file servers, p2p networks as well as individual computer systems,
  • elaboration of Internet based intelligence gathering system, both active and passive, and demonstrating its efficiency in a measurable way.

Sinister indeed.

Submission + - SPAM: Court to scammer: Give up your house or go to jail 1

coondoggie writes: "Too many online scammers get away with what amounts to a wrist slap but a case if Las Vegas this week seems to be heading the right direction at least.

According to the Federal Trade Commission, a business opportunity scammer has been held in contempt for the second time by a federal court and ordered to turn over the title of his home in Las Vegas or face jail time.

The court found that the operator of the scam, Richard Neiswonger, failed to deliver marketable title to his home, in violation of a previous court order entering a $3.2 million judgment against him, the FTC stated. The FTC charged that the defendant deceived consumers with false promises that they could make a six-figure income by selling his "asset protection services" to those seeking to hide their assets from potential lawsuits or creditors.

Sorry for the latency of the reply. My comment Karma ran out. I looked at long lists of Angel Clubs, but when that's when my insecurities regarding the execution of of the business kicks in. I really need a business guy/partner to carry this forward. Someone that would be comfortable with this phase of the start-up. I have what I think is a solid business plan and a strong patent on a novel technology, but frankly, I'm not the business guy to carry it off.

I knew I should have been a programmer. As each year goes by my hardware skills become less-and-less useful, because they keep moving the equipment to remote locations and handing-over control to programmers or administrators (or lawyers).

Oh well. (signs up for college). Time to earn that second degree (and maybe score with the ladies for a change).

Nothing stops anyone from using the APIs, I'm talking about a working implementation.

OpenGL is supported on pretty much all available platforms and has a standard implementation on them: Windows has opengl32.dll, Linux has Mesa3d, and Apple also has a default implementation.

I guess the point I'm trying to make here that an API is worthless without an implementation: the library containing the actual functionality. What are you loading if you don't have a IHV implementation available? Nothing. Just like OpenGL, OpenCL will need a default, software, implementation supported on all platforms.

And I can promise you that Microsoft will not be jumping on this OpenCL bandwagon (providing a platform default software implementation) with their development Direct3D Compute Shaders and the fact that Microsoft is no longer a Khronos partner. If they do in the next version of Windows I'll be very pleasantly surprised.

Comment Re:GPUs are dying - the cycle continues (Score 1) 176

CPUs are infamously bad at processing floating point operations, this is the reason that dedicated GPUs were invented in the first place. A graphics processor like the GTX 285 has 240 stream processors that are manufactured for processing floating point numbers but really bad at integer operations. A CPU like a Core 2 Quad has four cores that are really good at integer operations but requires CPU extensions like SSE to do high performance floating point operations.

Both Intel and AMD are currently manufacturing CPU/GPU hybrids that would kind of balance both these worlds: Larrabee a GPU-like addon, AMD Fusion an on-chip solution. We'll see what kind of API hell they will bring.

Comment Re:Isn't there a fundamental problem... (Score 2, Interesting) 176

IMO, the fundamental problem with OpenCL is the same as with OpenAL, which is that Operating System vendors don't provide a standard implementation as is done with OpenGL.

(Bus) speed isn't an issue as creating a CPU or GPU context requires a specific creation flag, so one would know what the target platform is.

Just one word came to mind when I read the blurb on the CentOS front page: unprofessional. Seeing a message like that on the site of the developer of my operating system would scare the crap out of me. Commercial software packages go on hiatus sometimes, nobody knows why, but at least they (AFAIK) don't scare their user base away by making a very public announcement about an individual teammate.
