HP kills WebOS devices :’-(

In addition, HP reported that it plans to announce that it will discontinue operations for webOS devices, specifically the TouchPad and webOS phones. HP will continue to explore options to optimize the value of webOS software going forward.

WebOS IMHO was the best smartphone OS there was, which never got the marketing push or hardware it deserved.

Tiny 3D Printer for home

at the Vienna University of Technology, a printing device has now been developed, which is much smaller, lighter and cheaper than ordinary 3D-printers. With this kind of printer, everyone could produce small, taylor-made 3D-objects at home, using building plans from the internet – and this could save money for expensive custom-built spare parts.

It’s also cheap to make the printer, making it a viable home unit.

Ultrafast quantum computer closer: Ten billion bits of entanglement achieved in silicon

Scientists from Oxford University have made a significant step towards an ultrafast quantum computer by successfully generating 10 billion bits of quantum entanglement in silicon for the first time — entanglement is the key ingredient that promises to make quantum computers far more powerful than conventional computing devices.

Probability microcips

The electrical signals inside Lyric’s chips represent probabilities, instead of 1s and 0s. While the transistors of conventional chips are arranged into components called digital NAND gates, which can be used to implement all possible digital logic functions, those in a probability processor make building blocks known as Bayesian NAND gates. Bayesian probability is a field of mathematics named after the eighteenth century English statistician Thomas Bayes, who developed the early ideas on which it is based.

Whereas a conventional NAND gate outputs a “1” if neither of its inputs match, the output of a Bayesian NAND gate represents the odds that the two input probabilities match. This makes it possible to perform calculations that use probabilities as their input and output.

Why computers suck at maths

This article explores why computers can’t do floating point maths, which is what makes Excel and all those online calculators such lousy mathematicians – basically because computers are binary, they can’t calculate anything after a decimal point, so the workaround is to put the number including the decimal point in a register of a certain size (say 32 bits) and reserve a few parts of the register for the decimal. Should the number you need to calculate become too big for the register, you run into trouble with rounding errors, which can compound. It then shows how nasty compound errors can become by citing the example of why a Patriot missle battery missed a Scud attack, resulting in the deaths of 24 people.

Fixing stuff goes faster with AR

Using Augmented Reality goggles, powered on an Android platform, marines are able to maintain their vehicles 46% faster than using a laptop with technical manuals.

The AR system provides label names to each object, shows a 3D model of the tool you need and gives instructions for specifica tasks overlaid on the camera view of what you are looking at.

Evolving swarm intelligence in robots

The Lausanne university in Switserland has moved from the software to the reality: they’ve managed to get robots to evolve and learn behaviours, as well as the behaviour to decieve and cooperate through communication (flashing lights) and movement. It’ s a very interesting experiment, showing that robots are getting smarter every day and are now showing some very very lifelike traits.

Melting memory chips in mass production : Nature News

Samsung Electronics announced this week that it has begun mass production of a new kind of memory chip that stores information by melting and freezing tiny crystals. Known as phase-change memory (PCM)

Unlike conventional memory, which involves moving electrons around a chip, PCM data would literally be frozen in place, even when the machine is off. That means these devices could switch on nearly instantaneously.

South Africa’s Telkom: faster internet via carrier pigeon

A South African IT firm sent a carrier pigeon 50 miles with a datacard attached to it’s leg. The pigeon was faster than the internet, which after 2 hours had only completed 4% of the transfer. This was in protest at the sucky internet connection available through Telkom.

DataSlide reinvents hard drive

DataSlide’s Hard Rectangular Drive (HRD) does not use read-write heads moving across the recording surface of a spinning hard disk drive (HDD). Instead an ultra-thin, 2-dimensional array of 64 read-write heads, operating in parallel, is positioned above an piezo-electric-driven oscillating rectangular recording surface, and delivers 160,000 random IOPS with a 500MB/sec transfer rate.

Ice air con system aims for cool on the cheap

The idea is to use cheap off-peak energy at night to freeze a tank of water or “distributed energy storage system” then use that great block of ice to cool your data centre in the daytime. Refrigerant would circulate from the tank to the Data Aire equipment eliminating the need to run the energy-intensive compressor and condenser during peak daytime hours.

Apparently this can save up to 45% on energy requirements for the cooling.

Pre Recovery Tool Leaks Out, Including webOS Root Image(!)

It’s only been a few days since the Palm Pre was released, but one of the biggest breakthroughs for the outside-the-system developer community may have just been made.

With this, people can probably tell how the OS hooks into the hardware, which will allow them to hook in themselves – something Palm itself has been loathe to share with their userbase.
