LaserMotive Finds Success In Space Elevator Competition 258

Bucc5062 writes "LaserMotive has achieved the first step towards the creation of a working space elevator by qualifying for the $900,000 prize in a contest sponsored by NASA. To achieve this first level, LaserMotive needed to propel a platform up a cable dangling from a helicopter at over 2 m/s. They hit a top speed of 4.13 m/s. The next level of qualification will be to achieve a climb speed greater then 5 m/s. LaserMotive beamed roughly 400 watts of laser power to a moving target at a distance of 1 kilometer, as part of the vertical laser alignment procedure. The target was a retro-reflective board a little larger than 1 meter on a side. The contest will continue for another two days with at least two other teams challenging for the prize. To win the Power Beaming competition, the LaserMotive system uses a high-power laser array to shine ultra-intense infrared light onto high-efficiency solar cells, converting the light into electric power which then drives a motor. 'Our system will track the vehicle as it climbs, compensating for motion due to wind and other changes. Building on our experience from last year’s competition, we are designing an improved system able to capture the full $2,000,000 prize.'"

Sony Demo'ing 360 Degree 3-D Tabletop Display 102

JoshuaInNippon writes "Sony announced via a Japanese press release that they will be showing off a prototype of a tabletop 360 degree 3-D display that can be seen in any direction without special glasses at the Digital Content Expo 2009 in Tokyo, from October 22-25. The device is quite small, at just over 10 inches tall and 5 inches in diameter. The display, using LEDs, currently supports an image that is 96 pixels wide by 128 pixels tall, with 24-bit full color. Sony also says it could have a number of applications, such as a digital sign, a digital frame, a medical display, or a virtual pet. Looking at the product image, who else wants to bet on the latter?)"

Comment But what about netloc absolutes? (Score 1) 620

Okay, so noone uses them, but TBL's own RFC in section C.1 demonstrates the use of an initial double-forward-slash meaning change the netloc without changing the protocol. This could be useful if you're dealing with resources that have the same mapping on multiple protocols (like http and https). I know it's a corner case, but it is still technically a documented use case...

The LHC, the Higgs Boson, and Fate 691

Reader Maximum Prophet sends a piece from the NY Times by the usually reliable Dennis Overbye reporting on a "crazy" theory being worked up by a pair of "otherwise distinguished physicists": that the Large Hadron Collider's difficulties may be due to the universe's reluctance to produce a Higgs boson. Maximum Prophet adds, "This happened to the Superconducting Super Collider in the science fiction story Einstein's Bridge. Now Holger Bech Nielsen, of the Niels Bohr Institute in Copenhagen, and Masao Ninomiya of the Yukawa Institute for Theoretical Physics in Kyoto, Japan, are theorizing that it's happening in real life." "I'm talking about the notion that the troubled collider is being sabotaged by its own future. A pair of otherwise distinguished physicists have suggested that the hypothesized Higgs boson, which physicists hope to produce with the collider, might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one, like a time traveler who goes back in time to kill his grandfather."

Submission + - How to monitor a MySQL server in real time?

oliderid writes: I have almost finished a web application that should support more than 100 queries per second some tables having more than 500.000 rows. Well I'm not used to this kind of load. I did my best to apply the best practices I could find over the web, reduce the queries to the database to the minimum, indexing, etc. but I'd like to have a GPL tool to monitor this database in real-time and see clearly how often a query is done, redundant ones, be sure that my mental is respected "One query per "page", processing time, etc. See when the server is about to be overloaded. The server is remote, Linux (redhat or ubuntu). There is no Xwindow, so I can monitor it through SSH/shell or through a web application. Any idea? Thx!

Image Recognition Neural Networks, Open Sourced 98

sevarac writes "The latest release of Java Neural Network Framework Neuroph v2.3 comes with ready-to-use image recognition support. It provides GUI tool for training multi layer perceptrons for image recognition, and an easy-to-use API to deploy these neural networks in end-user applications. This image recognition approach has been successfully used by DotA AutoScript tool, and now it is released as open source. With this Java library basic image recognition can be performed in just few lines of code. The developers have published a howto article and an online demo which can be used to train image recognition neural networks online."

LG Presents Solar Powered E-Book 139

MikeChino writes "At first glance, e-readers offer a great set of benefits over paper-bound books – they’re light, versatile, and a great alternative to lugging around a tote full of dead tree tomes on your next trip. However these new reading mediums have one glaring fault — can you imagine the frustration of running out of juice mid-sentence and halfway through Infinite Jest? LG's new solar e-book aims to address this issue by harnessing the sun's rays to power its display. The device features a 10 centimeter wide thin-film photovoltaic panel that can power the reader for a full day's worth of reading after 4-5 hours spent sitting in the sun."

Gigantic Air Gun To Blast Cargo Into Orbit 384

Hugh Pickens writes: "The New Scientist reports that with a hat tip to Jules Verne's From the Earth to the Moon , physicist John Hunter has outlined the design of a gigantic gun that could slash the cost of putting cargo into orbit. At the Space Investment Summit in Boston last week, Hunter described the design for a 1.1-kilometer-long gun that he says could launch 450-kilogram payloads at 6 kilometers per second. A small rocket engine would then boost the projectile into low-Earth orbit. The gun would cost $500 million to build, says Hunter, but individual launch costs would be lower than current methods. 'We think it's at least a factor of 10 cheaper than anything else,' Hunter says. The gun is based on the SHARP (Super High Altitude Research Project) light gas gun Hunter helped to build in the 1990s while at the Lawrence Livermore National Laboratory (LLNL) in California. With a barrel 47 meters long, it used compressed hydrogen gas to fire projectiles weighing a few kilograms at speeds of up to 3 kilometers per second."

Swarm — a New Approach To Distributed Computation 80

An anonymous reader writes "Ian Clarke, creator of Freenet, has been working on a new open source project called Swarm. The concept is to allow a computer program to be distributed across multiple computers in a manner almost completely transparent to the programmer. The system observes the program executing and figures out how the workload should be distributed for maximum efficiency. Swarm is implemented in Scala. Its at an early-prototype stage, and Ian has created a good 36 minute video explaining the concept and the current implementation."

An Electron Microscope For Your Home? 125

CuteSteveJobs writes "Could microscopy be in for a new golden age? Wired previewed the desktop-sized Hitachi TM-1000 Electron Microscope a while back. Light microscopes can magnify up to 400X (1,000X at lower quality) — just enough to see bacteria as shapes — but this one offers 20X to 10,000X, giving some amazing pictures. Unlike traditional electron microscopes, this one plugs into a domestic power socket and specimens don't need any special preparation; it's point-and-shoot, much like your typical digital camera. So easy a grade-schooler could use it, and earlier this year that's what happened: The kids at Iwanuma Elementary School in Miyagi, Japan got their own electron microscope. At $60,000, you'll have to give up on the BMW, but the hope is with economy of scale (so far 1,000 have sold) and miniaturization, the price will continue to drop. The only bad news? It runs XP."

London Stock Exchange Rejects .NET For Open Source 498

ChiefMonkeyGrinder writes "This summer, the London Stock Exchange decided to move away from its Microsoft .Net-based trading platform, TradElect. Instead, they'll be using the GNU/Linux-based MillenniumIT system. The switch is a pretty savage indictment of the costs of a complex .Net system. The GNU/Linux-based software is also faster, and offers several other major benefits. The details provide some fascinating insights into the world of very high performance — and very expensive — enterprise systems. ... [R]ather than being just any old deal that Microsoft happened to lose, this really is something of a total rout, and in an extremely demanding and high-profile sector. Enterprise wins for GNU/Linux don't come much better than this."

Submission + - Do you feed forward or back? (infoq.com)

Whispers_in_the_dark writes: "An InfoQ article describes the relative benefits of providing both feedback and feedforward criticism. It suggests that in many cases, utilizing feedforward to gather managerial and user input is more productive than feedback as it defuses much of the emotional charge. Additionally, it also encourages future thinking over post mortem analysis which could help shorten the meetings surrounding such events."

Ah, but can you turn up a bit more power in a matter of minutes not days?

One tricky part with managing the hosted hardware is figuring out how much you need. The beauty of cloud is that you don't need that calculation to produce a highly robust website. You _do_ need to still calculate and estimate costs, but if one uses reasonable worst cases one ends up with a model that's very close to normal hosting in price.

The difference is the disaster recovery, not the price (which you have to build into your software stack too!)
