Synaptics builds a fingerprint reader right into its trackpads

Consider the trackpad. The ones in Windows laptops are rarely (if ever) their best feature, but they nevertheless remain ubiquitous. Synaptics is one of the biggest names in trackpads, and today it announced a new one called the ” SecurePad ” that integrates a fingerprint reader into the trackpad itself rather than as a separate component. The SecurePad will have a small, 4mm by 10mm sensor on the trackpad’s surface that can scan a “fingertip placed at any angle on the sensor.” Said sensor will be available in a variety of different Synaptics trackpads, including the TouchPad , ClickPad , and ForcePad , and those trackpads will all be available in a variety of sizes. LED lights will provide feedback and allow the sensor to be used in dark environments. Fingerprint data traveling between the sensor and the “host processor” is encrypted to prevent the information from being accessed by other apps (Apple uses a similar sort of encryption with TouchID , and it prevents user apps from accessing fingerprint data in transit). We’ve contacted Synaptics to see if storing and reading fingerprints securely requires a separate chip to be installed in laptops that use the SecurePad and to get more detail on how this encryption works—we’ll update this article if we receive a response.

Bizarre Yelp lawsuit over alleged fake reviews to finally move ahead

A judge in San Diego, California,  ruled Tuesday against a local bankruptcy lawyer who had attempted to put a stop to Yelp’s lawsuit against him. Specifically, Julian McMillan asked the court more than six months ago to issue an anti-SLAPP ruling. A ” SLAPP ,” or strategic lawsuit against public participation, is a type of lawsuit meant to stifle speech—one where one party employs tactics against a smaller target by drawing out the suit in terms of time and money and intimidating the defendant. Yelp sued McMillan in August 2013. The  lawsuit , filed in San Francisco, alleges breach of contract, intentional interference with contract, unfair competition, and false advertising.

A silk casing enables long-lasting, implantable Wi-Fi medical devices

Not the silk casing discussed. Flickr user: CameliaTWU For a variety of medical reasons, it’s useful to implant devices inside the body. These devices may be needed to help regulate the cardiovascular system, or they can release drugs inside the body. Unfortunately, they’re also problematic. Once such a device has served its function, it must be removed, which necessitates another surgery. Plus, the presence can lead to complications such as infection, inflammation, and pain. To address some of these problems, scientists have developed new kinds of circuitry that can safely dissolve in the body. While these water-soluble devices don’t need to be removed, they come with a new problem—they dissolve too quickly for many purposes. So a group of researchers have now reported that they’ve developed a new way to control how long the devices last. The researchers propose that dissolving devices could be encased in a material made from silk protein and magnesium. The advantage of this approach comes from a property of the silk: its crystallinity. Different preparations of silk dissolve in water at different rates depending on their crystallinities. Altering this property allows researchers to choose among a range of dissolution times from only a few minutes up to a few weeks. This gives more control over the duration of the device, which is important, since different medical situations require devices that can last vastly different times.

Samsung 850 EVO SSD takes its storage into the third dimension

Things have advanced quite a bit since our last thoroughly in-depth look at how solid state disks work, and Samsung has been one of the biggest companies leading the charge toward faster, denser solid state drives. Its 840 EVO was the first consumer SSD to use TLC NAND—that’s triple-level cell NAND, which can store three bits per memory cell instead of one or two. Now, Samsung’s newest consumer SSD takes NAND density a step further, stacking the memory cells on top of each other in a complex sandwich. The 850 EVO, formally announced this morning , uses 32-layer TLC “V-NAND,” where the “V” stands for “vertical.” As we discussed previously at the 2013 Consumer Electronics Show, Samsung is the only SSD manufacturer that makes ” the whole widget “—it’s the only vertically integrated OEM that builds every part of the SSDs it sells, including the NAND that actually holds the data. This gives the company a distinct advantage over other SSD manufacturers—most of whom source their NAND from Samsung. The 850 EVO is set to be released in four capacities: 120GB, 250GB, 500GB, and 1TB. These are all decimal measurements, not binary—so that “1TB” is properly one trillion bytes, not 1024GB (there are official IEC units for binary measurements, but I’ll eat glass before I start saying ” tebibyte “). The quoted numbers on Samsung’s site look pretty good for a consumer-level drive: max sequential read speeds of 540MB/s, max sequential write speeds of 520MB/s, and relatively high IOPS across a variety of read and write regimes.

Linux Mint 17.1 review—less change is good change

The Linux Mint team recently released Linux Mint 17.1—a somewhat minor but still welcome upgrade to the Ubuntu-based ecosystem. And while Linux Mint 17.1 arrives as it usually does (a few weeks after the release of a new version of Ubuntu), version 17.1 is not based on Ubuntu’s latest effort, 14.10. Instead, this edition of Mint remains tied to the last Long Term Support (LTS) release, Ubuntu 14.04 . This marks the first time Linux Mint has not used the newest version of Ubuntu for a release. But if you paid attention to the curious approach of Linux Mint 17.0, you’ll know that was the plan all along. These days, Mint will not be changing its Ubuntu base again until the next LTS release—Ubuntu 16.04—arrives in 2016. And at first glance, it might seem like a bad thing. After all, Mint is missing out on whatever new stuff is in Ubuntu 14.10 (in this case it’s not much, but 15.04 will have plenty of changes). However, Mint 17.1 is in fact a very good sign for fans of the distro’s own tools, like its homegrown Cinnamon desktop. By relying on a consistent LTS release, Mint developers can more or less ignore the base system. Instead of spending all their time and effort making sure whatever Ubuntu has changed works with Mint, they can focus on what makes the ecosystem great—namely, its two primary desktops, MATE and Cinnamon.

AT&T still throttles “unlimited data”—even when network not congested

A while back, we reported that AT&T had stopped throttling unlimited data users except in cases when the network is congested. We were wrong. AT&T did change its policy to stop the automatic throttling of many unlimited data plans, but the company’s older, more draconian throttling policy still applies to customers with unlimited LTE data. AT&T told Ars the policy will be changed for all customers sometime in 2015, but it did not say whether that will happen closer to the beginning of the year or the end of the year. Here’s how it works: Customers who have 3G or non-LTE 4G phones and “ legacy unlimited data plans ” are throttled for the remainder of the billing period after they exceed 3GB of data in a month, but only “at times and in areas that are experiencing network congestion.” 4G and LTE are practically synonymous these days, but AT&T also applies the 4G label to its HSPA network technology.

Police officer fired for refusing to turn on body cam

The idea of putting body-worn cameras on police officers has spread since protests and unrest following the shooting of an unarmed teenager in Ferguson, Missouri. Earlier this week, the Obama administration proposed federal funding to get 50,000 more officers equipped with the cameras. The increased use of cameras makes a few policy questions around them more pressing. One such question: what happens when a police officer fails—or straight-up refuses—to turn on the body camera? The issue was highlighted in today’s Wall Street Journal , which features a story about a New Mexico police officer who “was fired for allegedly not following an order to record and upload all contacts with citizens,” according to the Albuquerque Police Department and the officer’s lawyer.

Android 5.0.1 released; fixes inadvertent factory reset bug

It seems like every big software release is quickly followed up by a bug fix update, and it looks like that’s what Google has just pushed out to AOSP and the Nexus image page . Android 5.0.1 is the latest version of Lollipop, and is now available for select devices. On the factory images page, there are downloads for the Wi-Fi Nexus 9 , Wi-Fi Nexus 7 (2013) , and the Nexus 10 , and we’re expecting updates for the rest of the Nexus devices soon. Google hasn’t said anything official about the update, but Peter Kiddier, an intrepid commenter  over at Android Police , has picked out the new commits from the source code. The major showstopper looks to be this bug , which, in some instances, could cause stray input on the lock screen to erase everything on the device. Read 5 remaining paragraphs | Comments

Netflix accused of creating fast lanes “at the expense of competitors”

Ajit Pai of the Federal Communications Commission today accused Netflix of “secur[ing] ‘fast lanes’ for its own content” at the expense of competitors and deploying proprietary caching systems in order to force Internet service providers to use nonstandard equipment. Pai, one of two Republican commissioners on the five-member commission, made the accusations in a letter to Netflix CEO Reed Hastings . The letter describes Netflix’s support for regulating ISPs as utilities in order to prevent them from charging content providers for “fast lanes” and then accuses Netflix of creating fast lanes for itself. Pai’s letter cites a TechCrunch article from May that quotes Hastings’ support for “strong net neutrality,” but it provides no sources for any of the accusations he made against Netflix. It reads as follows: Dear Mr. Hastings, Netflix has been one of the principal advocates for subjecting Internet service providers (ISPs) to public utility regulation under Title II of the Communications Act, arguing that this step is necessary to prevent the development of so-called “fast lanes” on the Internet. “The basic argument,” you have said, “is that we’re big believers in the free and open Internet.” For this reason, I was surprised to learn of allegations that Netflix has been working to effectively secure “fast lanes” for its own content on ISPs’ networks at the expense of its competitors. Recent press articles report that Netflix, our nation’s largest streaming video provider, has chosen not to participate in efforts to develop open standards for streaming video. Moreover, I understand that Netflix has taken—or at least tested—measures that undermine aspects of open standards for streaming video. Specifically, I understand that Netflix has at times changed its streaming protocols where open caching is used, which impedes open caching software from correctly identifying and caching Netflix traffic. Because Netflix traffic constitutes such a substantial percentage of streaming video traffic, measures like this threaten the viability of open standards. In other words, if standards collectively agreed upon by much of the industry cannot identify and correctly route Netflix traffic, those standards ultimately are unlikely to be of much benefit to digital video consumers. Some have suggested that Netflix has taken these actions because the company is currently installing its own proprietary caching appliances throughout ISPs’ networks as part of its Open Connect program. If ISPs were to install open caching appliances throughout their networks, all video content providers—including Netflix—could compete on a level playing field. If, however, ISPs were to install Netflix’s proprietary caching appliance instead, Netflix’s videos would run the equivalent of a 100-yard dash while its competitors’ videos would have to run a marathon. Because these allegations raise an apparent conflict with Netflix’s advocacy for strong net neutrality regulations, I thought that it was important to give you a chance to respond to them directly. I look forward to receiving a response to this letter by Tuesday, December 16. Sincerely, Ajit Pai Filling in the gaps Netflix declined to comment when contacted by Ars.

FBI seizes 20 boxes of documents on LAUSD iPad program

On Monday morning, the FBI seized 20 boxes of documents pertaining to a $1.3 billion iPad program from the Los Angeles Unified School District (LAUSD), according to the Los Angeles Times . The program, which was intended to give iPads to every student, teacher, and campus administrator of the nation’s second-largest school district, has met with many catastrophic difficulties, and this latest federal investigation led the new superintendent of the school system to shelve the project indefinitely on Tuesday. The program first hit a bump in the road back in 2013 when a number of students “hacked” the iPads —which is to say they deleted profile information that designated the user as a student, thus letting the student browse the Internet unencumbered by the filter restrictions enforced by the school district. At the same time, many teachers reported that they felt ill-equipped to use and teach with the iPads. In October, the LAUSD Superintendent John Deasy resigned amid allegations of malfeasance , although he claimed no wrongdoing. Deasy drew attention after the disclosure of his ties to Apple and curriculum-provider Pearson. On Tuesday, Deasy told the Los Angeles Times that he had had no contact with the FBI, nor did he know what the investigation was about. Ars contacted the FBI for more details about the investigation, but a spokesperson said she could not comment. Read 2 remaining paragraphs | Comments
