Amazon Is Making a ‘Lord of the Rings’ Prequel Series

Amazon is making a Lord of the Rings prequel TV series for its Amazon Instant streaming service. The show, which already carries a multi-season commitment, will “explore new storylines preceding J.R.R. Tolkien’s The Fellowship of the Ring.” TechCrunch reports: It’s possible the new series will mine the ponderous but rich Silmarillion for material, as fan fiction writers and lore aficionados have done for decades. The exploits of the Elf-Lords of old would make for a stirring epic, while many would thrill at the possibility of seeing Moria at the height of its grandeur. So much depends on the quality of the adaptation, though. Amazon has been pretty good about its Originals, but this will be an undertaking far beyond the scope of anything its studios and partners have yet attempted. Amazon is partnering with New Line Cinema, which of course was the film company behind the much-loved trilogy that began in 2001, and the Tolkien Estate, as well as HarperCollins for some reason. The deal also “includes a potential additional spin-off series, ” presumably if it’s popular enough. Read more of this story at Slashdot.

Linux Has a USB Driver Security Problem

Catalin Cimpanu, reporting for BleepingComputer: USB drivers included in the Linux kernel are rife with security flaws that in some cases can be exploited to run untrusted code and take over users’ computers. The vast majority of these vulnerabilities came to light on Monday, when Google security expert Andrey Konovalov informed the Linux community of 14 vulnerabilities he found in the Linux kernel USB subsystem. “All of them can be triggered with a crafted malicious USB device in case an attacker has physical access to the machine, ” Konovalov said. The 14 flaws are actually part of a larger list of 79 flaws Konovalov found in Linux kernel USB drivers during the past months. Not all of these 79 vulnerabilities have been reported, let alone patched. Most are simple DoS (Denial of Service) bugs that freeze or restart the OS, but some allow attackers to elevate privileges and execute malicious code. Read more of this story at Slashdot.

Jellyfish-inspired e-skin glows when it’s in ‘pain’

Artificial skin stands to have a variety uses, with potential applications in everything from robots to prosthetics. And in recent years, researchers have been able to instill sensory perception, like touch and pressure, into artificial skin. However, while those sorts of senses will be incredibly important in engineered skin, they’ve so far been rather limited. For example, while current versions can be quite sensitive to light touch, they don’t fare so well with high pressures that could cause damage. So researchers at the Huazhong University of Science and Technology in China set out to fix that problem and they drew their inspiration from jellyfish. The Atolla jellyfish can sense pressure in its surroundings and emits bright flashes of light when attacked. To mimic that and combine visual signals with pressure sensing, the researchers placed small silver wires within a stretchy material, which was able to produce electrical signals when light pressure was applied to it. In between two layers of that material, the researchers added an additional layer, which was embedded with phosphors — particles that can luminesce — that lit up when strong pressure was applied. As increasing amounts of pressure were applied to the layered electronic skin , the phosphors lit up more and more and overall the skin was able to register a much wider range of pressure than other versions have been able to achieve. In the image below, you can see the phosphors light up when a transparent “W”-shaped slab is pressed into the activated electronic skin. The high pressures registered by the phosphors are around the levels that become painful to humans, meaning the luminescent material can play the role of pain sensors found in real human skin and create a visual representation of “pain.” Further, the full range of pressure that this skin can sense more closely matches what real human skin can feel. And as the researchers point out, this capability makes this particular electronic skin a promising potential component to human-machine interfaces and intelligent robots . The work was recently published in ACS Applied Materials and Interfaces . Image: American Chemical Society Source: ACS Applied Materials and Interfaces

Samsung Made a Bitcoin Mining Rig Out of 40 Old Galaxy S5s

An anonymous reader quotes a report from Motherboard: Samsung is starting a new “Upcycling” initiative that is designed to turn old smartphones and turn them into something brand new. Behold, for example, this bitcoin mining rig, made out of 40 old Galaxy S5 devices, which runs on a new operating system Samsung has developed for its upcycling initiative. Samsung premiered this rig, and a bunch of other cool uses for old phones, at its recent developer’s conference in San Francisco. Upcycling involves repurposing old devices instead of breaking them down for parts of reselling them. The people at Samsung’s C-Lab — an engineering team dedicated to creative projects — showed off old Galaxy phones and assorted tablets stripped of Android software and repurposed into a variety of different objects. The team hooked 40 old Galaxy S5’s together to make a bitcoin mining rig, repurposed an old Galaxy tablet into a ubuntu-powered laptop, used a Galaxy S3 to monitor a fishtank, and programed an old phone with facial recognition software to guard the entrance of a house in the form of an owl. Samsung declined to answer specific questions about the bitcoin mining rig, but an information sheet at the developer’s conference noted that eight galaxy S5 devices can mine at a greater power efficiency than a standard desktop computer (not that too many people are mining bitcoin on their desktops these days).

Bloodhound preps for land speed record with 200MPH test run

It’s finally happened. Nine years after the Bloodhound project was announced at London’s Science Museum , the supersonic car has completed its first test runs. At a closed-off airstrip near Newquay airport, Cornwall, the monstrous vehicle roared across the tarmac at roughly 200 MPH. That figure is a long way off the team’s ultimate goal of 763 MPH, however, and a new world land speed record. Eventually, the team hopes to crack 1, 000 MPH at the dusty Kalahari desert in South Africa. Before then, however, the team had to prove that the car was more than vapourware and broken promises. Today, the car relied on a Eurojet EJ200 jet engine for thrust. That on its own could take the car to 650 MPH. The final configuration will also have a rocket system provided by Nordic aerospace company Nammo. For the initial record attempt, the Bloodhound will use a single monopropellant rocket which can produce around 40kN of thrust. It will then be swapped out for a hybrid rocket system that, combined with the jet engine, can carry the car to 1, 000 MPH. In total, the vehicle will produce 212kN of thrust, which is eight times the power output of a Formula 1 starting grid. To install the rocket system, however, Bloodhound needs cash. Funding has always been a problem for the team in Bristol, which relies on sponsorship and fan donations to operate. The trial runs in Cornwall, then, serve two purposes; they’re a vital form of testing, giving the team valuable data and insight into the practicalities of running the vehicle. They are, though, also a marketing tool which the team hopes will attract the interest and, ultimately, the cash of a deep-pocketed investor. Without extra funding, the team will have to delay its record attempt in late 2018. Bloodhound is driven by Andy Green, an RAF pilot who set the previous world land speed record with the Thrust SSC in 1997. He’ll be piloting the vehicle both for the initial land speed record (the team hopes to hit about 800 MPH) and the 1, 000 MPH attempt. Bloodhound is a complicated and intimidating car to operate, measuring 13.4 meters and weighing roughly seven and a half tonnes. In Cornwall, however, Green seemed unfazed —excited even — as he clambered into the cockpit. We’re not surprised; he’s waited as long as the public to finally push the accelerator pedal. Here’s hoping it won’t be quite as long before we see Bloodhound run again.

2 Million IoT Devices Enslaved By Fast-Growing BotNet

An anonymous reader writes: Since mid-September, a new IoT botnet has grown to massive proportions. Codenamed IoT_reaper, researchers estimate its current size at nearly two million infected devices. According to researchers, the botnet is mainly made up of IP-based security cameras, routers, network-attached storage (NAS) devices, network video recorders (NVRs), and digital video recorders (DVRs), primarily from vendors such as Netgear, D-Link, Linksys, GoAhead, JAWS, Vacron, AVTECH, MicroTik, TP-Link, and Synology. The botnet reuses some Mirai source code, but it’s unique in its own right. Unlike Mirai, which relied on scanning for devices with weak or default passwords, this botnet was put together using exploits for unpatched vulnerabilities. The botnet’s author is still struggling to control his botnet, as researchers spotted over two million infected devices sitting in the botnet’s C&C servers’ queue, waiting to be processed. As of now, the botnet has not been used in live DDoS attacks, but the capability is in there. Today is the one-year anniversary of the Dyn DDoS attack, the article points out, adding that “This week both the FBI and Europol warned about the dangers of leaving Internet of Things devices exposed online.” Read more of this story at Slashdot.

Discovery of 50km Cave Raises Hopes For Human Colonisation of Moon

New submitter Zorro shares a report: Scientists have fantasised for centuries about humans colonising the moon. That day may have drawn a little closer after Japan’s space agency said it had discovered an enormous cave beneath the lunar surface that could be turned into an exploration base for astronauts. The discovery, by Japan’s Selenological and Engineering Explorer (Selene) probe, comes as several countries vie to follow the US in sending manned missions to the moon. Using a radar sounder system that can examine underground structures, the orbiter initially found an opening 50 metres wide and 50 metres deep, prompting speculation that there could be a larger hollow. This week scientists at the Japan Aerospace Exploration Agency (Jaxa) confirmed the presence of a cave after examining the hole using radio waves. The chasm, 50km (31 miles) long and 100 metres wide, appears to be structurally sound and its rocks may contain ice or water deposits that could be turned into fuel, according to data sent back by the orbiter, nicknamed Kaguya after the moon princess in a Japanese fairytale. Jaxa believes the cave, located from a few dozen metres to 200 metres beneath an area of volcanic domes known as the Marius Hills on the moon’s near side, is a lava tube created during volcanic activity about 3.5bn years ago.

First Floating Wind Farm Delivers Electricity

The world’s first floating offshore wind farm began delivering electricity to the Scottish grid today. “The 30MW installation, situated 25km (15.5mi) from Peterhead in Aberdeenshire, Scotland, will demonstrate that offshore wind energy can be harvested in deep waters, miles away from land, where installing giant turbines was once impractical or impossible, ” reports Ars Technica. “At peak capacity, the wind farm will produce enough electricity to power 20, 000 Scottish homes.” From the report: The installation, called Hywind Scotland, is also interesting because it was built by Statoil, a Norwegian mega-corporation known for offshore oil drilling. Statoil has pursued offshore wind projects in recent years, using the companyâ(TM)s experience building and managing infrastructure in difficult open sea conditions to its advantage. Hywind Scotland began producing power in September, and today it starts delivering electricity to the Scottish grid. Now, all that’s left is for Statoil and its partner company Masdar to install a 1MWh lithium-ion battery, charmingly called âoeBatwind, â on shore. Batwind will help the offshore system regulate power delivery and optimize output. After a number of small demonstration projects, the five 6MW turbines are the first commercial turbines to lack a firm attachment to the seafloor. They’re held in place using three giant suction anchors, which are commonly used in offshore oil drilling. Essentially, an enormous, empty, upside-down âoebucketâ is placed on the seafloor, and air is sucked out of the bucket, which forces the bucket downward, further into the seafloor sediment. The report mentions a 2013 video that shows how offshore wind farms work. Read more of this story at Slashdot.
