Premium Mathematica software free on budget Raspberry Pi

Wolfram Research is giving away its Mathematica software for use on the diminutive, $25 Raspberry Pi computers -- and debuting a brand-new programming language.

Wolfram Research's Mathematica is available for free on Raspberry Pi machines.

Not since Steve Jobs' Next computers did Wolfram Research offer Mathematica, its premium mathematics, processing, and analysis software, for free.

The Next was an expensive, higher-end workstation. This time around, Wolfram is giving away Mathematica for computers at the opposite end of the spectrum: the diminutive, $25 Raspberry Pi.

It's a nice horse to hitch your cart to. Two million Raspberry Pi machines have been sold so far, and they're popular in the educational circles that Wolfram also targets.

Wolfram Research founder and Chief Executive Stephen Wolfram said Thursday that Mathematica is now available for Raspberry Pi computers and will ship with future models. In addition, the company also is including the first public prototype version of a new product, Wolfram Language.

"I'm a great believer in the importance of programming as a central component of education. And I'm excited that with the Wolfram Language I think we finally have a powerful programming language worthy of the next generation," Wolfram said. "We've got a language that's not mostly concerned with the details of computers, but is instead about being able to understand and create things on the basis of huge amounts of built-in computational ability and knowledge."

Those grand aspirations, to be sure, but they're nothing compared to how Wolfram introduced the Wolfram Language last week: "If we're forming a kind of global brain with all our interconnected computers and devices, then the Wolfram Language is the natural language for it."

Raspberry Pi machines -- naked circuit boards that run a version of Linux from an SD Card -- are geared for the hardware hacker crowd that's bubbling up in high-tech circles. They are of course not very powerful: Wolfram warns that Mathematica's graphical interface can be "sluggish." But the command-line interface is snappy, he said, and the machine is still vastly faster than those on which Mathematica got its start 25 years.

Mathematica is ordinarily expensive -- even the home version costs more than 10 times a Raspberry Pi, and the professional version is something like two orders of magnitude more costly than the tiny computer. But giving it away could make sense: Comparatively feeble Raspberry Pi machines are hardly likely to cut into sales of Mathematica on the workstations and laptops that paying customers use. And exposing students to new software and programming tools is a time-honored strategy to cultivate the next generation of customers.

How Leap Motion tracks what it can't see

We're not at "Minority Report" quite yet, but the latest Leap Motion upgrade and its new Freeform software have brought us one step closer to the dream of next-gen computing.

The new software upgrade to Leap Motion, which will be pushed to all devices in the coming months, makes the device's tracking even more precise to allow for unprecedented movement.

Leap Motion, makers of the matchbox-sized motion tracker that launched back in July, has gone even further in its efforts to make interacting with computers in open space as accurate and powerful as possible. An upcoming software upgrade announced Wednesday will allow any Leap Motion device to perform far more precise tracking by viewing one's hand as a whole object without needing to see its every move, allowing for new and more accurate forms of interaction.

The upgrade, which has been in the works for about a year and marks the first substantial overhaul to the device's software, is going out to all 85,000 developers in Leap's open-source community shortly and making its way to all Leap devices in the coming months, said CEO Michael Buckwald. "It takes the incredible tracking in our current generation of Leap and takes it the next level by being able to track things even when the device can't see them," he said.

"The way our tracking works now is what you see is what you get," said CTO David Holz. The upgrade, Holz explained, will let Leap track the hand as a general object now, allowing for actions like pinching, crossing fingers, moving one hand over another, and hand-to-hand interactions like brushing and tapping fingers on one another.

While those more precise movements sound arbitrary on the surface, the added accuracy to the Leap Motion tracking opens up an entirely new level of depth to hand movement that developers can utilize for new inputs or increased functionality.

"This makes it easier for developers to build even better physical experiences. It's about bringing everything closer to that original vision: how to bring the incredible power of hands and fingers to computers and make that interface disappear into the background," Buckwald added. "It's about making it as close to reality as possible."

"A lot of these improvements are important, but you don't necessarily notice them until you're used to the first," Holz said, noting how consumers are now conditioned to smartphone upgrades. "Otherwise they would never release a new phone. They would just wait until they had one that was infinitely fast."

And much in the same vein, Buckwald said, of Elon Musk's demo of spacecraft part building with Leap Motion in August, the company is also releasing for free a creation software tool called Freeform that allows users to experiment with geometric creation and manipulation. Like playing with clay on a pottery wheel, the app lets users distort any number of premade objects -- as well as import their own -- with a slew of tools and variables like object material to create digital sculptures and even 3D-printable objects.

"There are already apps for the very high end, like the SpaceX video using Siemens software with a Leap," Buckwald said. Freeform is intended to be somewhere between those professional-grade applications and one's that everyday consumers will find accessible.
