iFixit tore apart Apple's iPhone XS and iPhone XS Max, revealing very similar insides to last year's iPhone X. Engadget reports the findings: One of the most interesting features is the battery on the XS. The iPhone XS sports a slightly downgraded battery from the iPhone X, a 10.13 Wh battery (2,659 mAh at 3.81 V) versus 10.35 Wh (2716 mAh at 3.81 V). But a new configuration might more than make up for it: Apple is using a brand-new L-shaped single-cell battery instead of two separate batteries. However, the XS Max still sports two batteries. Some other tweaks include a new, Apple-branded power management chip and a new antenna line on the bottom of the phone. The camera bump is also slightly taller, meaning your iPhone X case might not fit on your XS, if you plan on upgrading. The Verge also notes that "there's no evidence that the teardown team could find of any improved water or dust resistance, despite the improved IP68 ratings on the iPhone XS and XS Max."

iFixit tore apart the new 2018 MacBook Pro keyboard to see how well the silicone membrane works to protect the butterfly mechanism from dust and debris. After showering a 2017 and 2018 MacBook Pro in dust particles, the repair site found the newer generation holds up surprisingly well. 9to5Mac reports: As shown in the photo, the blue paint particles coat the outside of the keycaps and the edges of the membrane, but the silicon covers stop most of the particles from getting into the key mechanism -- which is what causes the sticky key issues on the previous models. However, the silicon covers have to have holes in them to allow the keycap clips to attach. Naturally, dust can and will get through these holes over time. iFixit placed some sand particles into the "danger zones" of the keycaps, and confirmed the keys will break/become-unreliable when that happens, just like the second-generation butterfly keys. The non-cocooned 2017 keyboard was "almost immediately flooded" in the particles, unsurprisingly. Clearly, the 2018 model is greatly improved in regard to reliability, but it remains to be seen just how much better it is in real-world use. Over time, you only need a couple specks of dust to get in the keycaps and the keys will get stuck. It's just the chances of dust getting in are greatly reduced with the 2018 models.

According to a new survey from Common Sense Media and SurveyMonkey, 47% of parents worry their child is addicted to their mobile device. By comparison, only 32% of parents say they're addicted themselves. USA Today reports: Half of parents also say they are at least somewhat concerned about how mobile devices will affect their kids' mental health. Nearly one in five say they're "extremely" or "very" concerned. According to the survey, 89% of parents believe it's up to them to curb their children's smartphone usage. The survey conducted between Jan. 25 and Jan. 29 included a sample of 4,201 adults, including 1,024 parents with children under age 18. Data was weighted to reflect the demographic composition of the U.S. for adults over 18, based on Census data. Many devices and services feature parental controls, but some parents may not be aware they exist. The Common Sense-SurveyMonkey survey found 22% of parents did not know YouTube -- which has faced scrutiny over how easy it is for kids to find inappropriate videos -- offered parental controls. Also, 37% have not used the controls before. Among parents surveyed who say their kids watch YouTube videos, 62% said their kids have seen inappropriate videos on the site. Most, or 81%, said it's the parents' job to prevent kids from seeing these videos.

theodp writes: Computer Science Teacher Alfred Thompson wonders how other high school CS teachers use textbooks. "It's not a conversation I hear much about," he writes. Indeed, many teachers apparently don't rely on CS textbooks much at all. In fact, the highly-touted new AP Computer Science Principles (AP CSP) course does not require a CS textbook for students (sample College Board AP CSP syllabus), albeit to the chagrin of some. Some of the bigger providers of AP CSP curriculum -- e.g., BJC and Code.org, both of whom partner with Microsoft TEALS -- don't require a traditional CS textbook. But with teachers being recruited to teach Computer Science even if they don't have a CS background, should students learning CS have a textbook? Or is the high AP exam pass rate enjoyed by AP CSP students proof that no-more-books works?

America's largest ISP just rolled out a new service that allows small and medium-sized business owners "to oversee their organization" with continuous video surveillance footage that's stored in the cloud -- allowing them to "improve efficiency." An anonymous reader quotes the Philadelphia Inquirer: Inventory is disappearing. Workplace productivity is off. He said/she said office politics are driving people crazy. Who you gonna call...? Comcast Business hopes it will be the one, with the "SmartOffice" surveillance offering formally launched this week in Philadelphia and across "70 percent of our national [internet] service footprint," said Christian Nascimento, executive director of premise services for the Comcast division. Putting a "Smart Cities" (rather than "Big Brother is watching you") spin on "the growing trend for...connected devices across the private and public sectors," the SmartOffice solution "can provide video surveillance to organizations that want to monitor their locations more closely," Nascimento said...
The surveillance cameras are equipped with zoom lenses, night-vision, motion detection, and wide-angle lenses, while an app allows remote access to the footage from smartphones and tablets (though the footage can also be downloaded, or stored online for up to a month). Last year Comcast was heavily involved in an effort to provide Detroit's police department with real-time video feeds from over 120 local businesses, which the mayor said wouldn't have been successful "Without the complete video technology system Comcast provides."

Jason Koebler (3528235) writes "The cybersecurity bill making its way through the Senate right now is so broad that it could allow ISPs to classify Netflix as a "cyber threat," which would allow them to throttle the streaming service's delivery to customers. "A 'threat,' according to the bill, is anything that makes information unavailable or less available. So, high-bandwidth uses of some types of information make other types of information that go along the same pipe less available," Greg Nojeim, a lawyer with the Center for Democracy and Technology, said. "A company could, as a cybersecurity countermeasure, slow down Netflix in order to make other data going across its pipes more available to users.""

Taco Cowboy writes "Perhaps it's not much, but China has released a panoramic view of the moonscape where their lander has landed. They 'stitched' up some 60 photos taken by 3 cameras on the Chang'e 3 lander, taken from 3 different angles — Vertical, 15 degrees up, and 15 degrees down. From the picture, there is a significant sized crater is seen, several meters wide, off to the left of Yutu, the (jade rabbit) moon rover, and located only about 10 meters away from the Chang'e-3 lander."

jfruhlinger writes "In a political environment that's become very strongly defined by partisan lines, the SOPA debate has offered an unexpected ray of hope: the two main Congressional opponents of the bill are Ron Wyden, an Oregon Senator deemed a 'hardcore liberal' and Darrell Issa, a California Representative who is one of the Obama Administration's fiercest critics. (There are both Ds and Rs in favor of the bill, too.)" (Read more below.) In the technical rather than political world, opposition seems easier to find: Trailrunner7 writes "A group of engineers, networking specialists, security experts and other specialists deeply involved with the Internet's development and growth have sent a letter to lawmakers criticizing the highly controversial SOPA and PIPA bills and imploring them not to pass the legislation, which they say would stifle innovation and 'threaten engineers who build Internet systems or offer services that are not readily and automatically compliant with censorship actions by the U.S. government.' The letter is signed by a long list of Internet pioneers and other respected figures, including Steve Bellovin, Paul Vixie, Vint Cerf, Jon Callas, Tony Li, Robert W. Taylor, Esther Dyson and Fred Baker, among many others. Both SOPA and PIPA have been criticized heavily by technologists, privacy advocates and security experts who say that not only would the proposed bills make it difficult for companies to create innovative new technologies, but they also would likely not even accomplish the goals their authors' had in mind, namely preventing copyright infringement and content piracy."
