Ever had an officer pass up your clunker to snag a flashier vehicle? Well, there's now some data showing which vehicles accumulate the most tickets. According to a study by Insurance.com, drivers of the Subaru WRX, Pontiac GTO, and Scion FR-S get a higher percentage of tickets than drivers of any other cars. At the bottom of the list, we see vehicles such as the Ford Ecosport, the Land Rover LR4, and Chevy Sportvan. They have a widget that will let you see data on your own make/model, if you're curious.

00_NOP writes: Children in the U.K. have been taught in metric measures in school since (at least) 1972, but yesterday British Prime Minister David Cameron suggested that they should actually be taught in Imperial measures (which are still in use officially to measure road distances and speeds, but not really anywhere else). Is this because he hasn't a clue about science or because he is catering to a particular political base?

An anonymous reader writes: Contrary to what we were sometimes taught in high school physics, the Earth's gravity is not constant. It actually shows slight variations on different parts of the Earth's surface, and the variations correlate with the density of the material on that surface. The European Space Agency has been measuring gravity for four years, mapping these variations and recording the changes those variations have undergone. Its data indicates "a significant decrease [in gravity] in the region of Antarctica where land ice is melting fastest. Further analysis is, of course, planned so that the whole of Antarctica can be taken into account and "the clearest picture yet of the pace of global warming" can be determined on that continent.

wabrandsma sends this article from New Scientist: Hong Kong's mass protest is networked. Activists are relying on a free app that can send messages without any cellphone connection. Since the pro-democracy protests turned ugly over the weekend, many worry that the Chinese government would block local phone networks. In response, activists have turned to the FireChat app to send supportive messages and share the latest news. On Sunday alone, the app was downloaded more than 100,000 times in Hong Kong, its developers said. FireChat relies on "mesh networking," a technique that allows data to zip directly from one phone to another via Wi-Fi or Bluetooth. Ordinarily, if two people want to communicate this way, they need to be fairly close together. But as more people join in, the network grows and messages can travel further. Mesh networks can be useful for people who are caught in natural disasters or, like those in Hong Kong, protesting under tricky conditions. FireChat came in handy for protesters in Taiwan and Iraq this year."

Today the Federal Communications Commission eliminated its sport blackout rules, which prevented cable and satellite television providers from showing sporting events that were blacked out on a local station. It's common practice in the NFL to black out football games locally if the stadium didn't sell enough tickets. The ruling now removes government protections for the NFL's policies (the NFL can continue to black out local broadcasts). The FCC's decision is based on "significant changes" to the industry over the 40 years since the rules were adopted. Television has replaced ticket sales as the primary source of revenue, and the NFL is incredibly popular. They also don't think there's any chance the NFL will move its games to pay-per-view.

Today at a press conference in San Francisco, Microsoft announced the new version of their flagship operating system, called Windows 10. (Yes, t-e-n. I don't know.) With the new version of the operating system, they'll be unifying the application platform for all devices: desktops, laptops, consoles, tablets, and phones. As early leaks showed, the Start Menu is back — it's a hybrid of old and new, combining a list of applications with a small group of resizable tiles that can include widgets. Metro-style apps can now each operate inside their own window (video). There's a new, multiple-desktop feature, which power users have been demanding for years, and also a feature that lets users easily grab objects from one desktop and transfer it to another. The command line is even getting some love. The Technical Preview builds for desktops and laptops will be available tomorrow through the Windows Insider Program. They're requesting feedback from customers. Windows 10 will launch in late 2015.

jfruh writes While Windows-based tablets haven't exactly set the world on fire, Microsoft hasn't given up on them, and its hardware partners haven't either. HP has announced a series of Windows tablets, with the 7-inch low-end model, the Stream 7, priced at $99. The Stream brand is also being used for low-priced laptops intended to compete with Chromebooks (which HP also sells). All are running Intel chips and full Windows, not Windows RT.

An anonymous reader writes Matchstick and Mozilla today announced their open-source take on the Chromecast: a $25 Firefox OS-powered HDMI dongle. The streaming Internet and media stick will be available first through Kickstarter, in the hopes to drive down the price tag. Jack Chang, Matchstick General Manager in the US, described the device to me as "essentially an open Chromecast." He explained that while the MSRP is $25 (Google's Chromecast retails for $35), the Kickstarter campaign is offering a regular price of $18, and an early bird price of $12.

Czech37 writes Facebook may be among the world's most well-known tech companies, but it's not renowned for being at the forefront of open source. In reality, they have over 200 open source projects on GitHub and they've recently partnered with Google, Dropbox, and Twitter (among others) to create the TODO group, an organization committed to furthering the open source cause. In an interview with Opensource.com, Facebook's James Pearce talks about the progress the company has made in rebooting their open source approach and what's on the horizon for the social media network.
