Wolfram launches CDF, a new document format

Wolfram today rolled out its Computable Document Format, which is designed to turn documents into interactive applications.

The goal is to turn "lifeless documents" into ones that bring data to life, show the data behind assumptions and illustrate concepts. Conrad Wolfram, strategic director of Wolfram, said the CDF effort has now reached the point where the company can open it up to developers, publishers, and other interested parties.

Wolfram is still working out the business model behind CDF, but publishers have reportedly shown "great interest." For now, CDF is delivered via a free player that can bring infographics, journals, and math lessons to life. It's not a stretch to see how a magazine like Popular Science could publish in the CDF format.

The rub is that Wolfram needs adoption and there's already a dominant document format in Adobe's PDF. One big challenge would be figuring out the interplay between CDF and PDF. Would someone want to embed a CDF document into a PDF? Conrad Wolfram said that "the CDF format will be open" with the goal of becoming a public standard.

For now, Wolfram needs developers on board. CDF has reached the point where a developer with the know-how to author an XML document can bring publications to life. Indeed, the use cases for CDF revolve around journal articles, knowledge apps, textbooks, infographics, and presentations and reports.

Hasselblad's 200-megapixel camera: $45,000

The new top-end model from medium-format camera maker Hasselblad is now on the market, and it's not cheap: the 200-megapixel H4D-200MS will set you back 32,000 euros, or about $45,000.

The camera actually uses a sensor with a mere 50 megapixels, but with Hasselblad's multishot technology combines six shots into one. That means moving subjects such as fashion models need not apply. But a lot of this very high-end photography involves static subjects such as jewelry, watches, cars, and paintings for reproduction.

Hasselblad announced the H4D-200MS last September at the Photokina show. At the time, the … Read more

Fix random lengthy pauses in OS X by correcting bad blocks

If you find your Mac is running slowly, generally there are a few things you can do, including running a general maintenance routine, deleting unneeded files to keep at least 10 percent of your boot drive free, increasing the installed RAM, and quitting unused applications (both foreground and background) that you may have installed. In addition to this, one possible cause of slowdowns is if your hard drive contains undetected bad blocks, and forcing the system to remap them can result in things running smoothly again.

Hard disks are "block-based" storage systems, meaning that their writing surfaces are … Read more

DIY Lego large-format cam actually works

Sure, you've built houses and perhaps even the Death Star with Lego bricks before, but how about a 4x5 large-format film camera that actually works?

It took Birmingham, Ala., photographer Cary Norton more than a year to achieve what seemed like an impossible task. He painstakingly assembled the Legotron, Mark I using a 127mm F4.7 lens that he bought on eBay for $40 and an unknown number of Lego bricks. The camera measures approximately 7 inches by 6.5 inches by 7 inches.

He says that the focal range is limited to roughly 3 feet from about 1.5 feet, which makes it ideal for portrait photography. He's now working on the Mark II, which he hopes will be able to focus to infinity and has plans for a pinhole version, too. Norton has already shot four dreamy-looking photos with this beauty, which can be viewed on his blog, alongside photos of the entire process.

Large-format cameras are typically used by professional photographers and landscape artists, some of whom include Ansel Adams and Russell Wong.

If a 4x5 film camera is too expensive, you know what to do.
