This week Purism began shipping its mass-produced Librem 5 phone to customers, according to announcement from the company: The Librem 5 is a one-of-a-kind general-purpose computer in a phone form-factor that Purism has designed and built from scratch following a successful crowdfunding campaign that raised over $2.2 million. Both the hardware and software design is focused on respecting the end user's freedom and giving them control over their privacy and security.

The Librem 5 doesn't run Android nor iOS but instead runs the same PureOS operating system as Purism's laptops and mini PC.

The Librem 5 has unique hardware features including a user-removable cellular modem, WiFi card, and battery. Like with Librem laptops, the Librem 5 also features external hardware kill switches that cut power to the cellular modem, WiFi/Bluetooth, and front and back cameras and microphone so that the user can control when these devices are in use. All hardware switches can also be triggered together to enable "lockdown mode" which also disables the GPS, accelerometer and all other sensors...

Another unique feature of the Librem 5 is convergence: the ability to connect the Librem 5 to a monitor or laptop dock and use it as a desktop computer running the same full-sized desktop applications as on Librem laptops. When in a phone form-factor, applications behave much like "responsive websites" and change their appearance for the smaller screen. This allows you to use the Librem 5 as a phone, a desktop, or a laptop with the same applications and same files.
Their announcement notes their work on software making desktop applications "adaptive" to phone form factors, adding "This suite of software has now become the most popular software stack to use on other handheld Linux hardware." And they close with an appreciative comment from Purism's founder and CEO Todd Weaver:

"Shipping the Librem 5 has been an immense multi-year developmental effort. It is the culmination of people's desire to see an alternative to Android and iOS and fund it, coupled with dedication from a team of experts addressing hardware, kernel, operating system, and applications that has turned a lofty near-impossible goal into reality. We have built a strong foundation and with the continued support of customers, the community, and developers, we will continue to deliver revolutionary products like the Librem 5 running PureOS."

Nintendo has discontinued its 3DS handheld after about 76 million sales over a nine-and-a-half year period. The BBC reports: A notice on the Japanese firm's site says "manufacturing of the Nintendo 3DS family of systems has ended." The device had the ability to trick the human eye into seeing 3D images like those in some cinema screenings -- but without special glasses. However, its launch received a lukewarm reception and it only gained popularity later. The console's demise has long been expected. Last year, the company said it no longer planned to make any new first-party games for the system. It means the original Nintendo DS retains the title of being the bestselling mobile console. And the Nintendo Switch -- a hybrid handheld-and-home machine -- is the current focus of Nintendo's efforts.

Nintendo is going back to the beginning with a modern version of its original Game & Watch handheld that's been revamped with a full-color LCD. It can play Super Mario Bros. in honor of the franchise's 35th anniversary. The new handled was announced during a surprise Nintendo Direct showcase. From a report: In addition to Super Mario Bros., the handheld can also play Super Mario Bros: The Lost Levels (released in Japan as Super Mario Bros. 2) and an updated version of Game & Watch: Ball that stars Mario (instead of Mr. Game & Watch). [...] The Game & Watch: Super Mario Bros. handheld will be released on November 13th in "limited production" for $49.99.

swell shares the findings from a small pilot study that suggests a few minutes of looking into a deep red light could have a dramatic effect on preventing eyesight decline as we age. CNN reports: Researchers recruited 12 men and 12 women, whose ages ranged from 28 to 72. Each participant was given a small handheld flashlight that emitted a red light with a wavelength of 670 nanometers. That wavelength is toward the long end of the visible spectrum, and just short of an infrared wavelength, which tends to be invisible to the human eye. They spent three minutes each day looking into the light over a period of two weeks. The lights work on both cones and rods in the eye. Cones are photo receptor cells that detect color and work best in well-lit situations. Rods, which are much more plentiful, are retina cells that specialize in helping us see in dim light, according to the American Academy of Ophthalmology.

Researchers measured the cone function in subjects' eyes by having them identify colored letters with low contrast. And they measured their eyes' rod sensitivity by asking them to detect light signals in the dark. There was a 14% improvement in the ability to see colors, or cone color contrast sensitivity, for the entire two dozen participants. Improvement, however, was most significant in study participants over age 40. For those ages, cone color contrast sensitivity rose by 20% over the course of the study. That age bracket also saw significant increases in rod threshold, which corresponds to the ability to see in low light. Study participants under 40 also experienced some improvement, but didn't see the same jump as older subjects. Younger eyes haven't declined as much as older eyes.

Texas Instruments' $100 calculators have been required in classrooms for more than twenty years, as students and teachers still struggle to afford them. From a report: Texas Instruments released its first graphing calculator, the TI-81, to the public in 1990. Designed for use in pre-algebra and algebra courses, it was superseded by other Texas Instruments models with varying shades of complexity but these calculators remained virtually untouched aesthetically. Today, Texas Instruments still sells a dozen or so different calculator models intended for different kinds of students, ranging from the TI-73 and TI-73 Explorer for middle school classes to the TI-Nspire CX and TI-Nspire CX CAS ($149), an almost smartphone-like calculator with more processing power. But the most popular calculators, teachers tell me, include the TI-83 Plus ($94), launched in 1999; the TI-84 Plus ($118), launched in 2004; the very similar TI-84 Plus Silver Edition, also launched in 2004; and the TI-89 Titanium ($128).

Thompson (anecdote in the story), like many teachers, works in a district where it's a financial impossibility to ask students and their parents to shell out $100 for a new calculator. (Graphing calculators of any brand are recommended at Thompson's school, and they are essential for the curriculum.) So the onus falls on him and other teachers, who rely on their teacher salaries -- Thompson makes $62,000 a year -- to fill in the gaps. At first, Thompson bought cheaper calculators: four-function, $3 calculators. This, he quickly realized, would be insufficient. "A lot of students were angry and actually left the class and went to the classroom of the more experienced teacher next to me and asked to borrow her calculators," he told me. The bulky, rectangular Texas Instruments calculators act more like mini-handheld computers than basic calculators, plotting graphs and solving complex functions. Seeing expressions, formulas, and graphs on-screen is integral for students in geometry, calculus, physics, statistics, business, and finance classes. They provide students access to more advanced features, letting them do all the calculations of a scientific calculator, as well as graph equations and make function tables. Giving a child a four-function calculator -- allowing for only addition, subtraction, multiplication, and division -- would leave them woefully underprepared for the requirements of more advanced math and science classes.

Ever wondered what would manifest if you mixed 1990s nostalgia with a clever name and some futuristic hacking tech? The answer is the Pwnagotchi: a DIY, open source gadget for hacking Wi-Fi that gets smarter the more networks it gets exposed to using machine learning. From a report: It also has an adorable interface that reflects different "moods" depending on what it's doing, and echoes the Tamagotchi digital pets of the 90s. The idea is for its user to take it around the city and "feed" it with Wi-Fi handshakes, the process that allows phones or laptops to communicate with other wireless devices like a router or a smart TV. In theory, these handshakes can then be cracked to reveal the Wi-Fi network's password, which would be useful if the Pwnagotchi user wanted to hack into the Wi-Fi network at a later time. Hackers, of course, love it. The software for the Pwnagotchi was publicly released on September 19. Barely a month later, and with little promotion other than on Twitter, there's already an enthusiastic community of hundreds of security researchers and hackers all over the world who are playing with it, modding it, writing plugins to improve it, and helping each other out on a Slack channel.

Analogue is set to announce a new Game Boy clone. From a report: Analogue, known for their FPGA (Field Programmable Gate Array)-based hardware clones of the NES, SNES, and Sega Genesis/Megadrive, will be launching a handheld addition to their lineup called the "Analogue Pocket." The unit will be compatible with the entire library of Game Boy and Game Boy Color games, as well as Sega's Game Gear, SNK's Neo Geo Pocket Colour, and Atari's Lynx -- essentially bringing every 90's handheld under one hardware roof, without software emulation. The unit will also feature a 3.5" LTPS LCD at 1600 x 1440 resolution (615ppi), and USB-C charging port. Further reading: Game Boy has turned Game Man, just in time for the original device's 30th birthday.

Nintendo has confirmed the much-rumored Nintendo Switch Lite, revealing that the new slimmed down console -- available in gray, yellow, and turquoise -- will launch on September 20 for $199.99. From a report: The device, which first came to light last year, is $100 less expensive than its predecessor and, as such, it does lack a number of key features compared to its bigger brother. For example, the Nintendo Switch Lite only offers a single "handheld" game-play mode, compared to the additional "TV" and "tabletop" modes of the Nintendo Switch. While this raises questions about the use of "switch" in the device's name given that it doesn't actually switch between modes, it also means that compatible games are limited to those that support handheld mode in the Nintendo Switch Library. However, gamers will be able to buy separate Joy-Con controllers (and a device to charge them) to use wirelessly with other games that don't support handheld mode.

What we have not yet grasped is the way the tiny machines in front of us are remolding our skeletons, possibly altering not just the behaviors we exhibit but the bodies we inhabit. From a report: New research in biomechanics suggests that young people are developing hornlike spikes at the back of their skulls -- bone spurs caused by the forward tilt of the head, which shifts weight from the spine to the muscles at the back of the head, causing bone growth in the connecting tendons and ligaments. The weight transfer that causes the buildup can be compared to the way the skin thickens into a callus as a response to pressure or abrasion.

The result is a hook or hornlike feature jutting out from the skull, just above the neck. In academic papers, a pair of researchers at the University of the Sunshine Coast in Queensland, Australia, argues that the prevalence of the bone growth in younger adults points to shifting body posture brought about by the use of modern technology. They say smartphones and other handheld devices are contorting the human form, requiring users to bend their heads forward to make sense of what's happening on the miniature screens. Counter point: The absurd story about smartphones causing kids to sprout horns.

dryriver writes: If you had asked someone doing 3D graphics seriously back in 2000 what 3D technology will look like two decades away in 2019, they might have said: "Most internet websites will have realtime 3D content embedded or will be completely in 3D. 3D Games will look as good as movies or reality. Everyone will have a cheap handheld 3D scanner to capture 3D models with. High-end VR headsets, gloves, bodysuits and haptics devices will be sold in electronics stores. Still and video cameras will be able to capture true holographic 3D images and video of the real world. TVs and broadcast TV content will be in holographic 3D. 3D stuff you create on a PC will be realtime -- no more waiting for images to slowly render thanks to really advanced new 3D hardware. 3D content creation software will be incredibly advanced and fast to work with in 2019. Many new types of 3D input devices will be available that make working in 3D a snap."

Except of course that that in the real 2019, none of this has come true at all, and the entire 3D field has been stagnating very, very badly since around 2010. It almost seems like a small army of 3D technology geniuses pushed and pushed 3D software and hardware hard during the 80s, 90s, 2000s, then retired or dropped off the face of the earth completely around 10 years ago. Why is this? Are consumers only interested in Facebook, YouTube, cartoony PlayStation graphics and smartphones anymore? Are we never going to see another major 3D technology innovation push again?

Veteran software developer firm Panic, which has made its name through high-end Mac software as well as titles such as Firewatch, is expanding its work in games and moving in a very unexpected direction. This week, Panic unveiled Playdate, a tiny, yellow Game Boy-like device with a black-and-white screen, a few chunky buttons, and... a hand crank for controlling quirky games. From a report: Playdate is adorable and exciting and fun and technically impressive. They're making their own hardware (in conjunction with Swedish device makers Teenage Engineering). They wrote their own OS (there's no Linux). It has a high resolution 400 x 240 black and white display with no backlighting. It has a crank. It's going to cost only $149 -- $149! -- and that includes a "season" of 12 games from an amazing roster of beloved video game creators, delivered every Monday for 12 weeks. The idea of a new upstart, a company the size of Panic -- with only software experience at that -- jumping into the hardware game with a brand new platform harkens back to the '80s and '90s. But even back then, a company like, say, General Magic or Palm, was VC-backed and aspired to be a titan. To be the next Atari or Commodore or Apple.

In today's world all the new computing devices and platforms come from huge companies. Apple of course. All the well-known Android handset makers building off an OS provided by Google. Sony. Nintendo. Panic is almost cheating in a way because they're tiny. The Playdate platform isn't competing with the state of the art. It's not a retro platform, per se, but while it has an obviously nostalgic charm it is competing only on its own terms. Its only goal is to be fun. And aspects of Playdate are utterly modern: Wi-Fi, Bluetooth, apps and software updates delivered over-the-air. They're taking advantage of an aspect of today's world that is brand new -- the Asian supply chain, the cheapness of Asian manufacturing, the cheapness of CPU and GPU cycles that allows things like Raspberry Pi to cost just $35.

Facebook accidentally shipped "tens of thousands" of virtual reality (VR) controllers with bizarre hidden messages, including "Big Brother is Watching" and "The Masons Were Here," reports BusinessInsider. From the report: Nate Mitchell, the cofounder of Facebook-owned VR organisation Oculus, wrote on Twitter on Friday that the company inadvertently printed some unusual messages inside its Touch controllers, handheld devices for playing games and navigating inside VR. These messages were intended only for prototypes, he said -- but a mistake meant they were included in regular production devices. "Unfortunately, some 'easter egg' labels meant for prototypes accidentally made it onto the internal hardware for tens of thousands of Touch controllers," the tech executive wrote.

Version 6.50 of the PlayStation 4's firmware now allows you to remotely play your PS4 games from an iPhone or iPad. "To access it, you'll need to download the Remote Play app for your iOS device, and then pair it with your console," reports The Verge. "Compatible games can then be played over Wi-Fi using the on-screen buttons." From the report: Announced back in 2013, Remote Play originally let you stream games from a PS4 console to the handheld PlayStation Vita, but later in 2016, Sony released Remote Play apps for both Windows and Mac. Although Sony has yet to announce a broader Android version of the service, the existence of an Android version of the app that's exclusive to Sony Xperia phones suggests there aren't any technical barriers. Bringing the functionality to iOS is a huge expansion for Remote Play, although it's a shame that you're not officially able to pair a DualShock 4 controller with the app via Bluetooth for a more authentic experience (although some users have reported being able to get the controller working via a sneaky workaround). If you're prepared to use a non-Sony controller, then you'll be happy to know that MacStories is reporting that other MFi gamepads (such as the SteelSeries Nimbus) work just fine with the iOS app. Other limitations with the functionality are that you'll need an iPhone 7 or 6th-generation iPad or later to use it, and it's also only available over Wi-Fi. You can't use Remote Play from another location over a mobile network.

PS4 version 6.50 also adds the ability for you to remap the X and O buttons on the controller.

Sony has officially ended production of its PS Vita games console. The handheld console has been gradually phased out over the past few years -- and this weekend Sony announced it would be discontinuing the Vita's final two models. Polygon reports: Sony stopped regularly publicizing individual platform sales in its investor reports in 2013, so there are no official numbers for how the PS Vita sold over its seven-year lifespan. Estimates by third parties have placed it somewhere in the range of 10-15 million units.

Sony itself stopped making games for the Vita in 2015, and in 2018 ended the production of physical media games for the device. February was also the last month that the PlayStation Plus subscription service gave out games for the platform. The original PlayStation Vita (PCH-1000) launched in Japan on Dec. 17, 2011, and in North America on Feb. 15, 2012. A revised slimline model (PCH-2000) followed in 2013 and 2014.

An anonymous reader quotes a report from Ars Technica: A man attending this week's CES show in Las Vegas says that a lidar sensor from startup AEye has permanently damaged the sensor on his $1,998 Sony camera. Earlier this week, roboticist and entrepreneur Jit Ray Chowdhury snapped photos of a car at CES with AEye's lidar units on top. He discovered that every subsequent picture he took was marred by two bright purple spots, with horizontal and vertical lines emanating from them. "I noticed that all my pictures were having that spot," he told Ars by phone on Thursday evening. "I covered up the camera with the lens cap and the spots are there -- it's burned into the sensor." In an email to Ars Technica, AEye CEO Luis Dussan confirmed that AEye's lidars can cause damage to camera sensors -- though he stressed that they pose no danger to human eyes. "Cameras are up to 1000x more sensitive to lasers than eyeballs," Dussan wrote. "Occasionally, this can cause thermal damage to a camera's focal plane array." Chowdhury says that AEye has offered to buy him a new camera. The potential issue is that self-driving cars also rely on conventional cameras. "So if those lidars are not camera-safe, it won't just create a headache for people snapping pictures with handheld camera," reports Ars. "Lidar sensors could also damage the cameras on other self-driving cars."

"It's worth noting that companies like Alphabet's Waymo and GM's Cruise have been testing dozens of vehicles with lidar on public streets for more than a year," adds Ars. "People have taken many pictures of these cars, and as far as we know none of them have suffered camera damage. So most lidars being tested in public today do not seem to pose a significant risk to cameras."

According to a Navy Inspector General report, U.S. military troops used two Android apps that contained severe vulnerabilities in live combat scenarios. "The two apps are named KILSWITCH (Kinetic Integrated Low-Cost Software Integrated Tactical Combat Handheld) and APASS (Android Precision Assault Strike Suite)," reports ZDNet. From the report: Both apps work by showing satellite imagery of surroundings, including objectives, mission goals, nearby enemy and friendly forces. The two apps work as a modern-day replacement for radios and paper maps and allow troops to use a real-time messaging client to coordinate with other military branches, and even call in air-strike support with a few simple screen taps, according to a DARPA press release and accompanying YouTube video. The apps have been under development since 2012 and starting 2015, they have been made generally available to all U.S. troops via a public app store managed by the National Geospatial-Intelligence Agency. But according to a Navy Inspector General report from March that was made public today, both apps contained vulnerabilities that could have allowed enemy forces access to troops' information.

The heavily redacted report doesn't detail the nature of the two vulnerabilities, but it does point out that the Navy had failed to control the distribution of these two applications, and later failed to act in warning troops of the danger they were in for almost a year. The report says that the two apps, KILSWITCH and APASS, were never meant or approved to be deployed in live combat zones. But the two apps, because of their flashy features and easier to use interface, became wildly popular among U.S. troops, but also other military branches, including foreign allied forces.

An anonymous reader quotes a report from The Verge: The Federal Communications Commission (FCC) paved the way for improved GPS and location accuracy today, approving an order that will allow U.S. phones to access a European satellite system. The order allows non-federal consumer devices to access the European Union's version of GPS, which is also known as Galileo. The system is available globally, and it officially went live in 2016. By opening up access, devices that can retrieve a signal from both Galileo and the U.S. GPS system will see improved timing estimates and location reliability. The iPhone 8 was the first Apple product to support it. Other phone models from Huawei and Samsung support the system, too. "Since the debut of the first consumer handheld GPS device in 1989, consumers and industry in the United States have relied on the U.S. GPS to support satellite-based positioning, navigation, and timing services that are integral to everyday applications ranging from driving directions to precision farming," the FCC said in a release. Now, the U.S. system will be able to commingle with the European one, making the way for better reliability, range, and accuracy.

According to a recently published paper by Microsoft Research team, the company could be looking to launch physical controllers for mobile devices. From a report: The research paper documents some of the popular solutions to gaming via a touch screen, while hailing the Nintendo Switch and PlayStation Portable (PSP) for circumventing touch-based control limitations with full joysticks and buttons. From the paper [PDF]: As smartphones and tablets have become pervasive, so has mobile gaming. Not surprisingly, popular games for these platforms are focused on touchscreen-based interaction. However, many types of game are less well-suited to mobile devices. Despite systems like AdaptControl which can adapt to the 'drift' typically occurring when using virtual on-screen controls, touchbased emulations of traditional gaming controls like Dpads, buttons and joysticks are often unsatisfactory.

Mobile gaming devices like the Sony PlayStation Portable and Nintendo's DS and Switch are dedicated mobile gaming platforms which overcome these limitations via physical controls. The success of the Switch is testament to the value of mobile gaming with physical controls. A number of cheaper products allow a smartphone to be clipped into or onto a modified handheld gaming controller; these include the ION iCade mobile, the GameCase, the GameVice and products from Moga. However, the fixed form of these accessories means they are bulky and inflexible.

theodp writes: In an obituary of sorts for the standard probability tables that were once ubiquitous in introductory statistics textbooks, Rick Wicklin writes: "In my first probability and statistics course, I constantly referenced the 23 statistical tables (which occupied 44 pages!) in the appendix of my undergraduate textbook. Any time I needed to compute a probability or test a hypothesis, I would flip to a table of probabilities for the normal, t, chi-square, or F distribution and use it to compute a probability (area) or quantile (critical value). If the value I needed wasn't tabulated, I had to manually perform linear interpolation from two tabulated values. I had no choice: my calculator did not have support for these advanced functions. In contrast, kids today have it easy! When my son took AP statistics in high school, his handheld calculator (a TI-84, which costs about $100) could compute the PDF, CDF, and quantiles of all the important probability distributions. Consequently, his textbook did not include an appendix of statistical tables."

Recently the Palm Beach Post noted that 20% of the academic credit awarded at Florida Atlantic University is for online courses. So how can they stop cheaters? Where once it was enough for a professor to roam the aisles of a classroom, checking for cheat sheets and keeping an eye out for students signaling one another, proctoring today's tests often requires web cams and biometric IDs. A field of more than a dozen test-proctoring services has emerged in the past decade. Typically, the company gets some sort of visual on the test taker via a web cam and then asks the student to show the camera his or her ID. Other security layers can include software that recognizes faces or even keystroking patterns. The next step is to monitor the student during the test. In the online proctoring world, that is done in one of three ways:

* A remote but live proctor who watches in real time.
* A record-and-review method in which a proctor watches the testing session, but not in real time.
* An automated system, in which the software is programmed to spot abnormalities and flag them.
Honorlock -- one of the record-and-review outfits -- expected to proctor roughly 100,000 tests in the 2017-2018 school year, and promises schools that their solution also searches the web for copies of the test and automatically files takedown notices for any leaked copies, according to a link shared by Slashdot reader Presto Vivace. Besides filming students during tests, it also includes patented technology that "detects and prevents searching for test answers online from any secondary device." And it even verifies the identity of test takers using "any government issued" i.d. (like a driver's license or passport) or student ID which includes a photo.

One student complained on Reddit that "This seems crazy invasive and should probably be illegal," adding "is there anything passive aggressive you want me to say into the mic?" But what do Slashdot readers think? Should professors be remotely detecting searches on handheld devices, using photo IDs to verify identities -- and filming students taking tests?
