Today’s Google Doodle — in most of the world, at least — celebrates the 200th anniversary of George Boole’s birth. We all have a lot to thanks Boole for, as he created the mathematics that underpins the logical operations of computing.
Boolean algebra, as its become known, is the branch of mathematics that operates on values of true or false — usually written as 1 or 0 —to process logical statements. In turn, it’s possible to create complex conditional operations based on so-called logic gates which allow computers to make sense of concepts like OR and AND.
The Doodle itself shows how the output of several logical operations depending on whether values of x and y are true or false. When the x and y appear in the small ‘g’, the other letters light up their output becomes true. So, when’ x and y’ is true, the big ‘G’ lights up. If you’re wondering what XOR means, that’s the ‘exclusive or’—it’s only true when one of its inputs is true, but not when both are.
Boole himself was an English mathematician, who became the first professor of mathematics at Queen’s College, Cork. His research dug deep into differential equations and, most memorably, symbolic logic.

Apple has quietly released a new iOS app that allows users to map out the interior spaces of a building using just an iPhone.
Update: The app requires a special, registered account in order to be used. It’s unclear who will be able to obtain such a thing.
The app’s description reads:
“By dropping ‘points’ on a map within the Survey App, you indicate your position within the venue as you walk through. As you do so, the indoor Survey App measures the radio frequency (RF) signal data and combines it with an iPhone’s sensor data. The end result is indoor positioning without the need to install special hardware.”
Apple bought the start-up wifiSLAM two years ago, and with it the company’s ability to analyze and track RF signals from Wi-Fi access points to maps and determine a user’s location. It seems like at least some of that expertise has crept into Indoor Survey.
Apple’s been experimenting with a series of indoor positioning technologies over the past few years, testing its iBeacons in retail stores and inviting retailers to to submit indoor maps of large, successful stores for use in Apple Maps. Using Indoor Survey to crowdsource indoor maps may finally make them a more common addition to the world of digital navigation.

Nokia Networks has announced that it’s going to test out pCell, the new cellular data system created by Steve Perlman which embraces large quantities of mobile devices to actually speed up data provision.
Perlman is the brains behind the like of QuickTime, WebTV and OnLive, and he reckons the pCell technology, which is being commercialized by his Artemis Networks company, could transform the way we slurp up data on the move. Earlier this year, we explained how it works:
Where existing cellular networks have to be spaced out to avoid interference, leaving dead zones between them and slow speeds on the edges of each cell tower’s domain, pCell claims to actually take advantage of interference by intelligently overlapping wireless signals, creating localized pockets of signal right at your smartphone’s antenna. As each phone broadcasts its location, the pCell network figures out what combination of signals the pCell antennas need to transmit in order to add up to a stable connection. What’s more, it can apparently do that trick for loads of phones simultaneously, giving each of them a full speed data connection instead of one connection that gets throttled as the network gets crowded.
Speaking to Re/code, Nokia Networks’ Chief Technology Officer Hossein Moiin explained that he’s “seen the demo … in a very controlled environment, but it seems to work… What we’re doing next is demonstrating that it does work. I’m not 100 percent sold, but I’m a believer.”
The tests, scheduled to take place sometime next year, will trial the technology in congested areas, like indoor stadia, airports and perhaps even downtown city districts.
In theory, users shouldn’t notice what’s happening, other than a potential speed bump: Nokia will simply integrate the pCell technology into its systems, but users don’t have to do anything, as the whole thing runs on existing LTE infrastructure. If you want to know the ins and out of how it all works, there is a 99-page white paper explaining it.
As Re/code notes, many in the wireless industry remain skeptical as to whether pCell will actually work in the wild. Earlier this year, Dish announced that it wanted to use the technology, but the collaboration with Nokia Networks ushers in the first series of real tests. We might not have to wait much longer before we find out if Perlman’s claims are accurate.

Drone manufacturer DJI and Canonical, the corporate entity behind the Ubuntu Linux distribution, today announced the launch of Manifold, a small embedded computer that’s optimized for building applications for drones.
The Manifold only fits on top of DJI’s Matrice 100 platform, so don’t expect to put this one on your phantom drone. The $3,300 Matrice 100 is essentially DJI’s flying developer platform, with the ability to carry hardware like the Manifold and customizable sensors.
Inside, the Manifold features a quad-core ARM Cortex A-15 processor and an NVIDIA Kepler-based GPU. The GPU is obviously not there to render graphics, but to make use of its image processing and parallel computing power.
This, DJI argues, will enable “new artificial intelligence applications such as computer vision and deep learning.” The computer also features standard USB and Ethernet ports for attaching infrared cameras, atmospheric research devices, surveying equipment, and other sensors. There’s also an HDMI port for connecting monitors.
“With the Manifold, we are entering a new era of smarter, faster and more powerful aerial platforms. Manifold opens up for aerial and ground technology to intelligently work together to solve complex problems,” said Michael Perry, DJI’s director of strategic partnerships, in a statement today. “We are excited to see what applications our developer community will come up with for this new platform.”
Given the partnership with Canonical, it’s no surprise that the computer will run Ubuntu (in this case, the 14.04 Long Term Support version).
