Ask Slashdot: Where Can I Find Good Replacement Batteries? 131

An anonymous reader writes: I have an old phone with a battery that barely works anymore. My current phone's battery is mediocre — I can put up with it, but I've been thinking about getting a new one. My four-year-old ThinkPad holds less of a charge than I'd like, and less than it did when I bought it. In all these cases, the only thing holding me back from buying a new battery is that I'm not sure where to find a good one. Searching for my phone's battery on Amazon (or any major online retailer) yields a dozen results, all fairly cheap. But which are reliable? They all seem to have varying reviews, ranging from "Perfect official factory replacement!" to "Garbage knock-off, worse than the battery I replaced." Part numbers don't seem to help, as the knock-offs replicate those pretty well. I ask you, Slashdot: where can I find a good replacement battery?

Submission + - Google Wants To Test Driverless Cars in a Simulation (theguardian.com)

An anonymous reader writes: Google has been testing its autonomous vehicles on U.S. roads for a while now. In fact, they're required to, by law. "California's regulations stipulate autonomous vehicles must be tested under "controlled conditions" that mimic real-world driving as closely as possible. Usually, that has meant a private test track or temporarily closed public road." It's easy enough to test a few prototypes, but whenever autonomous cars start being produced by manufacturers, it'll become a lot more complicated. Now, Google is lobbying to change that law to allow testing via computer simulation. Safety director Ron Medford said, "Computer simulations are actually more valuable, as they allow manufacturers to test their software under far more conditions and stresses than could possibly be achieved on a test track." Google spokeswoman Katelin Jabbari said, "In a few hours, we can test thousands upon thousands of scenarios which in terms of driving all over again might take decades." Shee adds that simulator data can also easily provide information on how human behavior creeps into driving. "It's not just about the physics of avoiding a crash. It's also about the emotional expectation of passengers and other drivers." For example, when one of Google's computer-controlled cars is cut off, the software brakes harder than it needs to, because this makes the passengers feel safer. Critics say relying heavily on simulation data is flawed because it doesn't take into account how other cars react to the computer's driving.

Finding an ISIS Training Camp Using Google Earth 134

An anonymous reader writes: Terrorist organization ISIS has been in the news a lot lately for their hostile activities in Iraq and Syria. They've also been very active online, posting propaganda and photos on various social networking sites to try to recruit more members. Frequently, they'll have pictures of themselves in nondescript locations — but even carefully selected images give clues to a real location. Citizen journalists at Bellingcat analyzed a group of these photos, comparing buildings and bridges in the background to images from Google Earth. With very little to go on, they were able to pinpoint the location of a terrorist training camp.

Submission + - U.S. University Restricts Network Access to Social Media, Political Content 1

onproton writes: Northern Illinois University recently began restricting student access to webpages that contain "illegal or unethical" content which, according to University policy, includes resources used for "political activities...and the organization or participation in meetings, rallies and demonstrations." A student raised concerns after attempting to access the Wikipedia page for Westboro Baptist Church, and receiving a filter message informing him that his access of this page would likely violate the University's Acceptable Use Policy, along with a warning that "all violations would be reviewed." This has lead to questions about whether some policies that restrict student access to information are in the best interest of the primary goal of education.

Researchers Hack Gmail With 92 Percent Success Rate 87

A reader sends this report from CNET: Researchers at the University of California Riverside Bourns College of Engineering and the University of Michigan have identified a weakness they believe to exist across Android, Windows, and iOS operating systems that could allow malicious apps to obtain personal information. Although it was tested only on an Android phone, the team believes that the method could be used across all three operating systems because all three share a similar feature: all apps can access a mobile device's shared memory. "The assumption has always been that these apps can't interfere with each other easily," said Zhiyun Qian, an associate professor at UC Riverside. "We show that assumption is not correct and one app can in fact significantly impact another and result in harmful consequences for the user." To demonstrate the method of attack, first a user must download an app that appears benign, such as a wallpaper, but actually contains malicious code. Once installed, the researchers can use it to access the shared memory statistics of any process (PDF), which doesn't require any special privileges.

A Better Way To Make Mind-Controlled Prosthetic Limbs 28

the_newsbeagle writes: To make a brain-machine interface, you need a way to capture neurons' electric signals. The most precise and most invasive way uses implants that are stuck in the gray matter. The least precise and least invasive way uses EEG sensors stuck to the scalp. But researchers at Johns Hopkins University say there's a third way that gets the best of both worlds, which is not too invasive and fairly precise. They use ECoG systems, in which a mesh of electrodes is placed under the skull, draped over the surface of the cortex.

They're testing their systems on epilepsy patients, who have these ECoG systems inserted anyway while they're waiting for surgery (the electrodes record the source of their seizures). The researchers are capturing these patients' movement commands from their brains, and using them to control robotic limbs. Someday such a system could be used by amputees to control their prosthetic limbs.

Apple CarPlay Rollout Delayed By Some Carmakers 76

Lucas123 writes: Some car makers are delaying the implementation of Apple's CarPlay iPhone interface for vehicle infotainment systems. The delays, which are prompting manufacturers such as Mercedes, Volvo and Honda to push their announcement from 2014 to 2015, appear to be related to a few snags in the integration process or in choosing which model cars should have the middleware. At the same time, many of the automakers rolling out CarPlay are also implementing Android Auto, which will provide a vehicle head unit user interface for Android smartphones. Analysts believe the addition of Android Auto earlier this year may also be causing delays because manufacturers want to be able to announce availability of both platforms in their new model vehicles.

A Movie of Triton Made From Voyager 2's Fly-by 25 Years Ago 34

schwit1 writes: Using restored images taken by Voyager 2 when it flew past Neptune's moon Triton 25 years ago, scientists have produced a new map and flyby movie of the moon. "The new Triton map has a resolution of 1,970 feet (600 meters) per pixel. The colors have been enhanced to bring out contrast but are a close approximation to Triton's natural colors. Voyager's "eyes" saw in colors slightly different from human eyes, and this map was produced using orange, green and blue filter images. ... Although Triton is a moon of a planet and Pluto is a dwarf planet, Triton serves as a preview of sorts for the upcoming Pluto encounter. Although both bodies originated in the outer solar system, Triton was captured by Neptune and has undergone a radically different thermal history than Pluto. Tidal heating has likely melted the interior of Triton, producing the volcanoes, fractures and other geological features that Voyager saw on that bitterly cold, icy surface. Pluto is unlikely to be a copy of Triton, but some of the same types of features may be present." Dr. Paul Schenk provides provides further information on his blog, and the movie can be viewed here.

Students From States With Faster Internet Tend To Have Higher Test Scores 175

An anonymous reader sends word of correlation found between higher internet speeds and higher test scores. Quoting: The numbers—first crunched by the Internet provider comparison site HSI — show a distinct trend between faster Internet and higher ACT test scores. On the high end, Massachusetts scores big with an average Internet speed of 13.1Mbps, and an average ACT test score of 24.1. Mississippi, on the other hand, has an average speed of just 7.6Mbps and an average score of 18.9.

In between those two states, the other 48 fall in a positive correlation that, while not perfect, is quite undeniable. According to HSI's Edwin Ivanauskas, the correlation is stronger than that between household income and test scores, which have long been considered to be firmly connected to each other. The ACT scores were gathered from ACT.org, which has the official rankings and averages for the 2013 test, and the speed ratings were taken from Internet analytics firm Akamai's latest report.

According to IHS, adoption of Android Auto is expected to slightly outpace CarPlay with an annual growth rate of 179% compared to 165%. In 2020, for example, 40 million cars will roll off assembly lines with Android Auto versus 37 million with CarPlay.

Researchers Made a Fake Social Network To Infiltrate China's Internet Censors 49

Jason Koebler writes: In order to get inside China's notorious internet filter, Harvard researcher Gary King created his own fake social network to gain access to the programs used to censor content, so he could reverse-engineer the system. "From inside China, we created our own social media website, purchased a URL, rented server space, contracted with one of the most popular software platforms in China used to create these sites, submitted, automatically reviewed, posted, and censored our own submissions," King wrote in a study published in Science. "We had complete access to the software; we were even able to get their recommendations on how to conduct censorship on our own site in compliance with government standards."

33 Months In Prison For Recording a Movie In a Theater 465

An anonymous reader writes: Philip Danks used a camcorder to record Fast & Furious 6 in a U.K. cinema. Later, he shared it via bittorrent and allegedly sold physical copies. Now, he's been sentenced to 33 months in prison for his actions. "In Court it was claimed that Danks' uploading of Fast 6 resulted in more than 700,000 downloads, costing Universal Pictures and the wider industry millions of pounds in losses." Danks was originally told police weren't going to take any action against him, but he unwisely continued to share the movie files after his initial detainment with authorities.
