But it may be premature to declare CAPTCHA technology dead (Photo: Maen Zayyad/Shutterstoc...

San Francisco-based artificial intelligence startup Vicarious has announced that it has developed software algorithms which can solve CAPTCHAs up to 90 percent of the time. Though CAPTCHAs are any automated test which differentiates between humans and computers, they often take the form of strings of partly distorted letters and numbers which many websites use to check that a visitor is human, the idea being that a computer cannot read the disguised text while a human (hopefully) can. It’s this type of CAPTCHA that Vicarious’s algorithms are designed to beat, and the high success rate renders the current standard of text-based CAPTCHAs ineffective, the company claims.  Read More

Before there were iPads, there were Macs. That's true historically, and it's also true at today's Apple event in San Francisco. Before unveiling its new iPad and iPad mini, Apple ran through some updates to its traditional PC line, including new 4th gen. Intel Core-powered MacBook Pros, as well as that redesigned Mac Pro that the company previewed back in June.  Read More

Gizmag compares the features and specs of the Microsoft Surface 2 (left) and Surface Pro 2

The Microsoft Surface has been, by just about any measure, a commercial flop. When your company writes off US$900 million in unsold stock, well, that writing is on the wall. But that doesn't mean the first-generation Surface and Surface Pro haven't made some customers very happy. If you're part of that, ahem, "elite" group, or think you might be sometime soon, do you spring for the Surface 2 or the Surface Pro 2? Join Gizmag, as we compare Microsoft's second round of hybrid tablets.  Read More

What weighs 5 tons and has less computing power than your watch? A pioneering piece of computing history call "Flossie," the last operating ICT 1301 mainframe. The National Museum of Computing recently took delivery of the dismantled computer, which needed three moving vans to bring it to the museum’s storage facility in Milton Keynes, UK.  Read More

Useful Chrome extensions for useful people

It's the world's most used web browser, but how many users are using extensions to get the most out of Google Chrome? (Probably very many. That's just the sort of annoying question journalists like to ask by way of an introduction.) Here are some of my favorites, not geared towards any particular profession, which I think could prove useful to my fellow generalist web users out there in the world. There are no gimmicks; no bossy extensions telling you what or what not to do; merely usefulness, hopefully.  Read More

Undetectable hardware Trojans could subvert cryptographic security (Image: Shutterstock)

Researchers have shown that it is possible to compromise the functioning of a cryptographic chip without changing its physical layout. Based on altering the distribution of dopants in a few components on the chip during fabrication, this method represents a big challenge for cyber-security as it is nearly impossible to detect with any currently practical detection scheme.  Read More

Terrafab generates 3D-printable models from geographical data

Here's a bit of fun. Terrafab is a web app that uses a simple, familiar map interface with which visitors can select their favorite piece of Norway to 3D print at home (or order a print of, if they're yet to take the home-3D printing plunge).  Read More
