Open Source OCR That Makes Searchable PDFs 133

An anonymous reader writes "In my job all of our multifunction copiers scan to PDF but many of our users want and expect those PDFs to be text searchable. I looked around for software that would create text searchable pdfs but most are very expensive and I couldn't find any that were open source (free). I did find some open source packages like CuneiForm and Exactimage that could in theory do the job, but they were hard to install and difficult to set up and use over a network. Then I stumbled upon WatchOCR. This is a Live CD distro that can easily create a server on your network that provides an OCR service using watched folders. Now all my scanners scan to a watched folder, WatchOCR picks up those files and OCRs them, and then spits them out into another folder. It uses CuneiForm and ExactImage but it is all configured and ready to deploy. It can even be remotely managed via the Web interface. Hope this proves helpful to someone else who has this same situation."

Boeing Shows Off First Commercial Spacecraft 114

coondoggie writes "Boeing today released the first public glimpse of the commercial spacecraft it is working on under an $18 million contract with NASA. Boeing's Crew Space Transportation (CST)-100 can hold seven crew and will be bigger than Apollo but smaller than NASA's Orion, and be able to launch on a variety of different rockets, including Atlas, Delta and Falcon.The company envisions the spacecraft supporting the International Space Station and future Bigelow Aerospace Orbital Space Complex systems. Bigelow is building what it calls 'expandable habitats,' that which are inflatable spacecraft would act as large, less costly space stations."

NASA Creates First Global Forest Map Using Lasers 55

MikeCapone writes "Scientists, using three NASA satellites, have created a first-of-its-kind map that details the height of the world's forests. The data was collected from NASA's ICESat, Terra and Aqua satellites. The latter two satellites are responsible for most of NASA's Gulf spill imagery. The data collected will help scientists understand how the world's forests both store and process carbon. While there are many local and regional canopy maps, this is the very first global map using a uniform method for measure."

World's Smallest Superconductor Discovered 72

arcticstoat writes "One of the barriers to the development of nanoscale electronics has potentially been eliminated, as scientists have discovered the world's smallest superconductor. Made up of four pairs of molecules, and measuring just 0.87nm, the superconductor could potentially be used as a nanoscale interconnect in electronic devices, but without the heat and power dissipation problems associated with standard metal conductors."

Visual Studio 2010 Forces Tab Indenting 390

An anonymous reader writes "For years, Microsoft has allowed Visual Studio users to define arbitrary tab widths, often to the dismay of those viewing the resultant code in other editors. With VS 2010, it appears that they have taken the next step of forcing tab width to be the same as the indent size in code. Two-space tabs anyone?"

Submission + - Contributors Leaving Wikipedia in Record Numbers

Hugh Pickens writes: "CNET reports that the volunteers who create Wikipedia's pages, check facts and adapt the site are abandoning Wikipedia in unprecedented numbers with tens of thousands of editors going “dead” — no longer actively contributing and updating the site — a trend many experts believe could threaten Wikipedia’s future. In the first three months of 2009 the English-language version of Wikipedia suffered a net loss of 49,000 contributors, compared with a loss of about 4,900 during the same period in 2008. “If you don’t have enough people to take care of the project it could vanish quickly," says Felipe Ortega at the Universidad Rey Juan Carlos in Madrid who created a computer system to analyze the editing history of more than three million active Wikipedia contributors in ten different languages. "We’re not in that situation yet. But eventually, if the negative trends follow, we could be in that situation.” Contributors are becoming disenchanted with the process of adding to the site which is becoming increasingly difficult says Andrew Dalby, author of The World and Wikipedia: How We are Editing Reality and a regular editor of the site. “There is an increase of bureaucracy and rules. Wikipedia grew because of the lack of rules. That has been forgotten. The rules are regarded as irritating and useless by many contributors.” Arguments over various articles have also taken their toll. "Many people are getting burnt out when they have to debate about the contents of certain articles again and again," adds Ortega."

Submission + - Amazing Software Turns Cheap Webcam Into Instant 3 (wired.com)

tugfoigel writes: It is called ProFORMA, or Probabilistic Feature-based On-line Rapid Model Acquisition, but it is way cooler than it sounds. The software, written by a team headed by Qi Pan, a student at the Department of Engineering at Cambridge University in England, turns a regular, cheap webcam into a 3D scanner.

Normally, scanning in 3D requires purpose-made gear and time. ProFORMA lets you rotate any object in front of the camera and it scans it in real time, building a fully 3D texture mapped model as fast as you can turn an object. Even more impressive is what happens after the scan: The camera continues to track the object in space and matches its movement instantly with the on-screen model.

Submission + - Diamonds Deliver Speed Boost To Quantum Computers (gizmag.com)

ElectricSteve writes: Scientists at UC Santa Barbara have made important advances in the field of spintronics by demonstrating the ability to electrically manipulate, at room temperatures, the quantum states of electrons trapped in the atomic structural defects of diamond crystals. Despite previous indications to the contrary, such quantum states can be manipulated very quickly, even at gigahertz frequencies, paving the way to significantly faster quantum computing.

Submission + - DroboPro 8-Bay In-depth: Hardware RAID at its Best 1

Vigile writes: Everyone seems to love Drobo storage products, especially the new additions to their line, but some remain hesitant to move to an external solution using a non-standard RAID level. PC Perspective's destroyer of SSD's took a crack at the DroboPro, doing his best to trip it up, and exploring all of its features in detail. As it turns out the DroboPro got the better of the tester and was able to survive all sorts of simulated destruction including yanking out the power cord during streaming writes to the unit. The unfortunate part is that the DroboPro is limited to iSCSI, Firewire, USB and eSATA connections for a steep $1495 retail price.

Major IE8 Flaw Makes "Safe" Sites Unsafe 83

After this weekend's report of a dangerous flaw in IE (which Microsoft confirmed today), intrudere points out an exclusive report in The Register on a new hole in IE8 that could allow an attacker to pull off cross-site scripting attacks on Web sites that ought, by rights, to be safe from XSS. This is according to two anonymous sources, who told El Reg that Microsoft had been notified of the vulnerability a few months ago.

New Theory of Gravity Decouples Space & Time 575

eldavojohn writes "Petr Horava, a physicist at the University of California in Berkeley, has a new theory about gravity and spacetime. At high energies, it actually snips any ties between space and time, yet at low energies devolves to equivalence with the theory of General Relativity, which binds them together. The theory is gaining popularity with physicists because it fits some observations better than Einstein's or Newton's solutions. It better predicts the movement of the planets (in an idealized case) and has a potential to create the illusion of dark matter. Another physicist calculated that under Horava Gravity, our universe would experience not a Big Bang but a Big Bounce — and the new theory reproduces the ripples from such an event in a way that matches measurements of the cosmic microwave background."
