Civil Construction Wipes Out Internet Connectivity Across Africa

An anonymous reader writes: Submarine cable operator Seacom has announced that civil construction activity was the cause of widespread outages which left large parts of Africa without internet connectivity yesterday. According to the firm, its Northern Trans-Egypt cable was damaged between Cairo and Alexandria, and the Southern Trans-Egypt route was also disrupted outside of Cairo. Adding to the interruption, Seacom’s backup route, the West Africa Cable System (WACS), was also down at the same time, leaving most African countries without connectivity.

Samsung Begins Mass Production of World’s Fastest DRAM

MojoKid writes: Late last year marked the introduction of High Bandwidth Memory (HBM) DRAM courtesy of AMD’s Fury family of graphics cards, each of which sports 4GB of HBM. HBM allows these new AMD GPUs to tout an impressive 512GB/sec of memory bandwidth, but it’s also just the first iteration of the new memory technology. Samsung has just announced that it has begun mass production of HBM2. Samsung’s 4GB HBM2 package is built on a 20 nanometer process. Each package contains four 8-gigabit core dies built on top of a buffer die. Each 4GB HMB2 package is capable of delivering 256GB/sec of bandwidth, which is twice that of first generation HBM DRAM. In the example of NVIDIA’s next gen GPU technology, code named Pascal, the new GPU will utilize HBM2 for its frame buffer memory. High-end consumer-grade Pascal boards will ship with 16GB of HBM2 memory (in four, 4GB packages), offering effective memory bandwidth of 1TB/sec (256GB/sec from each HMB2 package). Samsung is also reportedly readying 8GB HBM2 memory packages this year. Read more of this story at Slashdot.

Serious Linux Kernel Vulnerability Patched

msm1267 writes: A patch for a critical Linux kernel flaw, present in the code since 2012, is expected to be pushed out today. The vulnerability affects versions 3.8 and higher, said researchers at startup Perception Point who discovered the vulnerability. The flaw also extends to two-thirds of Android devices, the company added. An attacker would require local access to exploit the vulnerability on a Linux server. A malicious mobile app would get the job done on an Android device. The vulnerability is a reference leak that lives in the keyring facility built into the various flavors of Linux. The keyring encrypts and stores login information, encryption keys and certificates, and makes them available to applications. Here’s Perception Point’s explanation of the problem.

Much more than Mario Kart: The history of kart racers

No video game genre divides and unifies us like the kart racer. For every Mario Kart there are a dozen by-the-numbers cash-ins, and even that hallowed series receives regular criticism as too derivative. But while we all breathe a collective sigh of disappointment with each kid-friendly license that predictably goes the generic kart-racing route, it’s hard not to get excited by that rare entry that feels fresh and new. A great kart racer is a joyous thing. It’s accessible yet deep, fun yet primed for oh-so-serious competition between friends, and full of colorful, wacky charm. It is a game for everyone. So in keeping with the spirit of the genre—and as the latest edition in our gaming genre history series that includes  city builders , graphic adventures , and simulation games —it’s time to ride through the ups and downs of kart racing. (Before we start, a quick note: I’ve omitted go-kart racing sims such as Open Kart and Michael Schumacher Racing World Kart because they are essentially conventional racing games and not what we normally think of as kart racers.)

US government announces $4 billion self-driving car program

Turns out we’re way closer to our self-driving car future than most of us expected. US Department of Transportation Secretary Anthony Foxx announced at the Detroit Auto Show (pdf) Thursday that the Obama administration will have a national blueprint for autonomous vehicle standards by July. What’s more the administration is earmarking $4 billion of the 2017 budget to create a decade-long program that will support and accelerate development of the technology. “We are on the cusp of a new era in automotive technology with enormous potential to save lives, reduce greenhouse gas emissions, and transform mobility for the American people, ” Secretary Foxx said in a statement. Currently, each state has individual laws regarding the burgeoning technology. This forces automakers and early adopters like Google to juggle multiple sets of rules and regulations, depending on where in the country the technology is being built. For example, California recently decided that a human “driver” be present at all times should something go wrong. This program should reduce the number of hoops companies have to jump through by creating an overarching, national-level development framework.

Yahoo releases massive 13.5TB web-browsing data set to researchers

Yahoo’s business may be struggling , but millions of people still visit its site to read the news every day. That gives the company unique insights into browsing and reading habits, and today the company has released a huge swath of that data. The “Yahoo News Feed dataset” incorporates anonymous browsing habits of 20 million users between February and May of 2015 across a variety of Yahoo properties, including its home page, main news site, Yahoo Sports, Yahoo Finance, Yahoo Movies and Yahoo Real Estate. All told, the data set is a whopping 13.5TB and covers 110 billion unique interaction “events.” Yahoo calls it the “largest machine learning dataset” ever publicly released, and we’re inclined to believe them — there aren’t very many companies who could accumulate this much browsing data. It’s a huge amount of data, but fortunately you don’t need to worry about advertisers mining it to make more targeted ads. Yahoo is specifically releasing it only to the academic research community to help people build more effective recommendation algorithms. As noted by the MIT Technology Review , the data set includes includes headlines that Yahoo’s personalization algorithms show to visitors, a summary of the article, and which specific articles people click. There’s also some demographic data for about 7 million users that includes age, gender and location — but it’s all been anonymized. Improving recommendation algorithms is particularly relevant right now, as some of the biggest web properties rely on good recommendation engines to engage with their user. Netflix, Amazon, Google, Apple and Facebook (just to name a few) all rely on serving their users relevant recommendations to keep them engaged with their products and services. Yes, it’s a way for those companies to make more money, but it also generally makes for a better user experience — as long as those recommendations are good. Yahoo’s huge data release will probably go a long way towards meeting that goal. [Image credit: Noah Berger/Bloomberg via Getty Images] Source: Yahoo (Businesswire)

EU Companies Can Monitor Employees’ Private Conversations While At Work

An anonymous reader writes: A recent ruling of the European Court of Human Rights has granted EU companies the right to monitor and log private conversations that employees have at work while using the employer’s devices. The ruling came after a Romanian was fired for using Yahoo Messenger back in 2007, while at work, to have private conversations with his girlfriend. He argued that his employer was breaking his right for privacy and correspondence. Both Romanian and European courts disagreed. Read more of this story at Slashdot.

Verizon Accused of Helping Spammers By Routing Millions of Stolen IP Addresses

An anonymous reader writes: Spamhaus, an international non-profit organization that hunts down spammers, is accusing Verizon of indifference and facilitation of cybercrime because it failed for the past six months to take down stolen IP routes hosted on its network from where spam emails originated. Spamhaus detected over 4 million IP addresses, mainly stolen from China and Korea, and routed on Verizon’s servers with forged paperwork. Spamhaus says, “For a start, it seems very strange that a large US-based ISP can be so easily convinced by abusers to route huge IP address blocks assigned to entities in the Asian-Pacific area. Such blocks are not something that can go unnoticed in the noise of everyday activity. They are very anomalous, and should call for an immediate accurate verification of the customer. Internal vetting processes at large ISPs should easily catch situations so far from normality.” Read more of this story at Slashdot.

Graphene Flakes Facilitate Neuromorphic Chips

An anonymous reader writes: One of the hot areas of semiconductor research right now is the creation of so-called neuromorphic chips — processors whose transistors are networked in such a way to imitate how neurons interact. “One way of building such transistors is to construct them of lasers that rely on an encoding approach called “spiking.” Depending on the input, the laser will either provide a brief spike in its output of photons or not respond at all. Instead of using the on or off state of the transistor to represent the 1s and 0s of digital data, these neural transistors rely on the time intervals between spikes.” Now, research published in Nature Scientific Reports has shown how to stabilize these laser spikes, so that they’re responsive at picosecond intervals. “The team achieved this by placing a tiny piece of graphene inside a semiconductor laser. The graphene acts as a ‘saturable absorber, ‘ soaking up photons and then emitting them in a quick burst. Graphene, it turns out, makes a good saturable absorber because it can take up and release a lot of photons extremely fast, and it works at any wavelength; so lasers emitting different colors could be used simultaneously, without interfering with each other—speeding processing.” Read more of this story at Slashdot.

Trend Micro Flaw Could Have Allowed Attacker To Steal All Passwords

itwbennett writes: Trend Micro has released an automatic update fixing the problems in its antivirus product that Google security engineer Tavis Ormandy discovered could allow “anyone on the internet [to] steal all of your passwords completely silently, as well as execute arbitrary code with zero user interaction.” The password manager in Trend’s antivirus product is written in JavaScript and opens up multiple HTTP remote procedure call ports to handle API requests, Ormandy wrote. Ormandy says it took him 30 seconds to find one that would accept remote code. He also found an API that allowed him to access passwords stored in the manager. This is just the latest in a string of serious vulnerabilities that have been found in antivirus products in the last seven months. Read more of this story at Slashdot.
