AI-Assisted Fake Porn Is Here and We’re All Screwed

New submitter samleecole shares a report from Motherboard: There’s a video of Gal Gadot having sex with her stepbrother on the internet. But it’s not really Gadot’s body, and it’s barely her own face. It’s an approximation, face-swapped to look like she’s performing in an existing incest-themed porn video. The video was created with a machine learning algorithm, using easily accessible materials and open-source code that anyone with a working knowledge of deep learning algorithms could put together. It’s not going to fool anyone who looks closely. Sometimes the face doesn’t track correctly and there’s an uncanny valley effect at play, but at a glance it seems believable. It’s especially striking considering that it’s allegedly the work of one person — a Redditor who goes by the name ‘deepfakes’ — not a big special effects studio that can digitally recreate a young Princess Leia in Rouge One using CGI. Instead, deepfakes uses open-source machine learning tools like TensorFlow, which Google makes freely available to researchers, graduate students, and anyone with an interest in machine learning. Anyone could do it, and that should make everyone nervous. Read more of this story at Slashdot.

AMD Quietly Made Some Radeon RX 560 Graphics Cards Worse

Brad Chacos: When the Radeon RX 560 launched in April it was the only RX 500-series card with a meaningful under-the-hood tech boost compared to the RX 400-series. The graphics processor in the older RX 460 cards packed 14 compute units and 896 stream processors; the upgraded Radeon RX 560 bumped that to 16 CUs and 1, 024 SPs. Now, some — but not all — of the Radeon RX 560s you’ll find online have specs that match the older 460 cards, and sometimes run at lower clock speeds to boot. AMD’s Radeon RX 560 page was also quietly altered to include the new configurations at some point, Heise.de discovered. The last snapshot of the page by the Internet Archive’s Wayback Machine occurred on July 7 and only lists the full-fat 16 CU version of the card, so the introduction of the nerfed 896 SP model likely occurred some time after that. Sifting through all of the available Radeon RX 560s on Newegg this morning reveals a fairly even split between the two configurations, all of which are being sold under the same RX 560 name. In a statement, AMD acknowledged the existence of 14 Compute Unit (896 stream processors) and 16 Compute Unit (1024 stream processor) versions of the Radeon RX 560. “We introduced the 14CU version this summer to provide AIBs and the market with more RX 500 series options. It’s come to our attention that on certain AIB and etail websites there’s no clear delineation between the two variants. We’re taking immediate steps to remedy this: we’re working with all AIB and channel partners to make sure the product descriptions and names clarify the CU count, so that gamers and consumers know exactly what they’re buying. We apologize for the confusion this may have caused.” Read more of this story at Slashdot.

‘Watershed’ Medical Trial Proves Type 2 Diabetes Can Be Reversed

dryriver writes: For those suffering from type 2 diabetes, there is good news. Nearly half of the participants in a watershed trial of a new diabetes treatment were able to reverse their affliction. The method is quite simple — an all liquid diet that causes participants to lose a lot of weight, followed by a carefully controlled diet of real solid foods. Four times a day, a sachet of powder is stirred in water to make a soup or shake. They contain about 200 calories, but also the right balance of nutrients. If the patient can keep away from other foods long enough, there is a chance of reversing type 2 diabetes completely. Prof Roy Taylor, from Newcastle University, told the BBC: “It’s a real watershed moment. Before we started this line of work, doctors and specialists regarded type 2 as irreversible. But if we grasp the nettle and get people out of their dangerous state (being overweight), they can get remission of diabetes.” However, doctors are not calling this a cure. If the weight goes back on, then the diabetes will return. The trial only looked at people diagnosed with diabetes in the last six years. Doctors believe — but do not know with absolute certainty yet — that in people who have had the affliction much longer than that, there may be too much permanent damage to make remission possible. The trial results have been published in the Lancet medical journal. Read more of this story at Slashdot.

Man Hacks Jail Computer Network To Get Inmate Released Early

An anonymous reader writes: A Michigan man pleaded guilty last week to hacking the computer network of the Washtenaw County Jail, where he modified inmate records in an attempt to have an inmate released early. To breach the jail’s network, the attacker used only spear-phishing emails and telephone social engineering. The man called jail employees and posed as local IT staffers, tricking some into accessing a website, and downloading and installing malware under the guise of a jail system upgrade. Once the man (Konrads Voits) had access to this data, investigators said he accessed the XJail system, searched and accessed the records of several inmates, and modified at least one entry “in an effort to get that inmate released early.” Jail employees noticed the modification right away and alerted the FBI. The man as arrested a month later and is now awaiting sentencing (maximum 10 years and a fine of up to $250, 000). Read more of this story at Slashdot.

Voyager 1 Fires Up Thrusters After 37 Years

If you tried to start a car that’s been sitting in a garage for decades, you might not expect the engine to respond. But a set of thrusters aboard the Voyager 1 spacecraft successfully fired up Wednesday after 37 years without use. NASA announces: Voyager 1, NASA’s farthest and fastest spacecraft, is the only human-made object in interstellar space, the environment between the stars. The spacecraft, which has been flying for 40 years, relies on small devices called thrusters to orient itself so it can communicate with Earth. These thrusters fire in tiny pulses, or “puffs, ” lasting mere milliseconds, to subtly rotate the spacecraft so that its antenna points at our planet. Now, the Voyager team is able to use a set of four backup thrusters, dormant since 1980. “With these thrusters that are still functional after 37 years without use, we will be able to extend the life of the Voyager 1 spacecraft by two to three years, ” said Suzanne Dodd, project manager for Voyager at NASA’s Jet Propulsion Laboratory, Pasadena, California.

Two Technologists Create Black Metal Album Using An AI

An anonymous reader quotes a report from The Outline: Coditany of Timeness” is a convincing lo-fi black metal album, complete with atmospheric interludes, tremolo guitar, frantic blast beats and screeching vocals. But the record, which you can listen to on Bandcamp, wasn’t created by musicians. Instead, it was generated by two musical technologists using a deep learning software that ingests a musical album, processes it, and spits out an imitation of its style. To create Coditany, the software broke “Diotima, ” a 2011 album by a New York black metal band called Krallice, into small segments of audio. Then they fed each segment through a neural network — a type of artificial intelligence modeled loosely on a biological brain — and asked it to guess what the waveform of the next individual sample of audio would be. If the guess was right, the network would strengthen the paths of the neural network that led to the correct answer, similar to the way electrical connections between neurons in our brain strengthen as we learn new skills.

Every iPhone X Is Not Created Equal

According to a PC Magazine report that uses data from Cellular Insights, the Qualcomm-powered iPhone X has better LTE performance than the Intel-powered model. From the report: There are three iPhone X models sold globally. Using lab equipment, Cellular Insights tested two of them: the Qualcomm-powered A1865, sold by Sprint, Verizon, and U.S. Cellular and in Australia, China, and India; and the Intel-powered A1901, sold by most other global carriers including AT&T and T-Mobile. (The third model, A1902, is only sold in Japan.) Here in the U.S., we anticipate that the SIM-free model sold directly by Apple will be the A1865, as that’s the model that supports all four U.S. carriers. For this test, Cellular Insights looked at performance on LTE Band 4, which is used by every major U.S. carrier except Sprint, as well as in Canada and parts of Latin America. Cellular Insights attenuated an LTE signal from a strong -85dBm until the modems showed no performance. While both modems started out with 195Mbps of download throughput on a 20MHz carrier, the Qualcomm difference appeared quickly, as the Intel modem dropped to 169Mbps at -87dBm. The Qualcomm modem took an additional -6dBm of attenuation to get to that speed. Most consumers will feel the difference in very weak signal conditions, where every dBm of signal matters, so we zoomed in on that in the chart below. At very weak signal strength, below -120dBm, the Qualcomm modem got speeds on average 67 percent faster than the Intel modem. The Intel modem finally died at -129dBm and the Qualcomm modem died at -130dBm, so we didn’t find a lot of difference in when the modems finally gave out. Read more of this story at Slashdot.

Sensitive Personal Information of 246,000 DHS Employees Found on Home Computer

The sensitive personal information of 246, 000 Department of Homeland Security employees was found on the home computer server of a DHS employee in May, according to documents obtained by USA TODAY. From the report: Also discovered on the server was a copy of 159, 000 case files from the inspector general’s investigative case management system, which suspects in an ongoing criminal investigation intended to market and sell, according to a report sent by DHS Inspector General John Roth on Nov. 24 to key members of Congress. The information included names, Social Security numbers and dates of birth, the report said. The inspector general’s acting chief information security officer reported the breach to DHS officials on May 11, while IG agents reviewed the details. Acting DHS Secretary Elaine Duke decided on Aug. 21 to notify affected employees who were employed at the department through the end of 2014 about the breach. Read more of this story at Slashdot.

A Stable Plasma Ring Has Been Created In Open Air For the First Time Ever

New submitter mrcoder83 shares a report from Futurism: Engineers from the California Institute of Technology (Caltech) have been able to create a stable plasma ring without a container. According to the Caltech press release, it’s “essentially capturing lightning in a bottle, but without the bottle.” This remarkable feat was achieved using only a stream of water and a crystal plate, made from either quartz and lithium niobate. The union of these tools induced a type of contact electrification known as the triboelectric effect. The researchers blasted the crystal plate with an 85-micron-diameter jet of water (narrower than a human hair) from a specially designed nozzle. The water hit the crystal plate with a pressure of 632.7 kilograms of force per centimeter (9, 000 pounds per square inch), generating an impact velocity of around 305 meters per second (1, 000 feet per second) — as fast as a bullet from a handgun. Plasma was formed as a result of the creation of an electric charge when the water hit the crystal surface. The flow of electrons from the point of contact ionizes the molecules and atoms in the gas area surrounding the water’s surface, forming a donut-shaped glowing plasma that’s dozens of microns in diameter. Caltech posted a video of the plasma ring on their YouTube channel. Read more of this story at Slashdot.
