Mac OS 10.9’s Mail App — Infinity Times Your Spam

An anonymous reader writes “Email service FastMail.fm has an blog post about an interesting bug they’re dealing with related to the new Mail.app in Mac OS 10.9 Mavericks. After finding a user who had 71 messages in his Junk Mail folder that were somehow responsible for over a million entries in the index file, they decided to investigate. ‘This morning I checked again, there were nearly a million messages again, so I enabled telemetry on the account … [Mail.app] copying all the email from the Junk Folder back into the Junk Folder again!. This is legal IMAP, so our server proceeds to create a new copy of each message in the folder. It then expunges the old copies of the messages, but it’s happening so often that the current UID on that folder is up to over 3 million. It was just over 2 million a few days ago when I first emailed the user to alert them to the situation, so it’s grown by another million since. The only way I can think this escaped QA was that they used a server which (like gmail) automatically suppresses duplicates for all their testing, because this is a massively bad problem.’ The actual emails added up to about 2MB of actual disk usage, but the bug generated an additional 2GB of data on top of that.” Read more of this story at Slashdot.

AMD’s Radeon R9 290X Launched, Faster Than GeForce GTX 780 For Roughly $100 Less

MojoKid writes “AMD has launched their new top-end Radeon R9 290X graphics card today. The new flagship wasn’t ready in time for AMD’s recent October 8th launch of midrange product, but their top of the line model, based on the GPU codenamed Hawaii, is ready now. The R9 290 series GPU (Hawaii) is comprised of up to 44 compute units with a total of 2, 816 IEEE-2008 compliant shaders. The GPU has four geometry processors (2x the Radeon HD 7970) and can output 64 pixels per clock. The Radeon R9 290X features 2816 Stream Processors and an engine clock of up to 1GHz. The card’s 4GB of GDDR5 memory is accessed by the GPU via a wide 512-bit interface and the R290X requires a pair of supplemental PCIe power connectors—one 6-pin and one 8-pin. Save for some minimum frame rate and frame latency issues, the new Radeon R9 290X’s performance is impressive overall. AMD still has some obvious driver tuning and optimization to do, but frame rates across the board were very good. And though it wasn’t a clean sweep for the Radeon R9 290X versus NVIDIA’s flagship GeForce GTX 780 or GeForce GTX Titan cards, AMD’s new GPU traded victories depending on the game or application being used, which is to say the cards performed similarly.” Read more of this story at Slashdot.

DARPA Issues $2mil Cyber Grand Challenge

First time accepted submitter Papa Fett writes “DARPA announced the Cyber Grand Challenge (CGC)–the first-ever tournament for fully automatic network defense systems. International teams will compete to build systems that reason about software flaws, formulate patches and deploy them on a network in real time. Teams would be scored against each other based on how capably their systems can protect hosts, scan the network for vulnerabilities, and maintain the correct function of software. The winning team would receive a cash prize of $2 million , with second place earning $1 million and third place taking home $750, 000.” Read more of this story at Slashdot.

Exoplanet Count Peaks 1,000

astroengine writes “The first 1, 000 exoplanets to be confirmed have been added to the Europe-based Extrasolar Planets Encyclopaedia. For the last few weeks, astronomers (and the science media) have been waiting with bated breath as the confirmed exoplanet count tallied closer and closer to the 1, 000 mark. Then, with the help of the Super Wide Angle Search for Planets (SuperWASP) collaboration, the number jumped from 999 to 1, 010 overnight. All of the 11 worlds are classified as ‘hot-Jupiters’ with orbital periods between 1 day and 9 days.” Read more of this story at Slashdot.

A Look Inside the 8K Theater Technology At the Newly Renovated Fiske Planetarium

An anonymous reader writes “Sky gazers at CU-Boulder’s Fiske Planetarium are getting better, clearer and deeper views. And not just of astronomy anymore. The planetarium has been upgraded, transforming it into a digital IMAX-like theater that’s open to the public every Saturday and Sunday with a variety of programs including shows for children. ‘Fiske’s refurbished video system projects ultra high-definition pictures at 8, 000 by 8, 000 pixels in size, giving audience members a crystal-clear 360-degree view on the dome’s 65-foot screen. “The size and quality is the equivalent of 40 Blu-ray players projecting 40 sections of one video image at once, ” said [Doug Duncan, director of Fiske]. This gallery of images shows a behind-the-scenes look at the Planetarium’s brand new 8k Fulldome projection system. ‘ In addition to space odysseys and laser shows — longtime favorites of audiences — movies are now part of the Fiske lineup. ‘Just like at an IMAX theater, we can take you near a black hole, through the Grand Canyon, under the ocean, or up to a super volcano, ‘ said Duncan. “The sky is no longer the limit.'” Read more of this story at Slashdot.

Simple Bug Exposed Verizon Users’ SMS Histories

Trailrunner7 writes “A security researcher discovered a simple vulnerability in Verizon Wireless’s Web-based customer portal that enabled anyone who knows a subscriber’s phone number to download that user’s SMS message history, including the numbers of the people he communicated with. The vulnerability, which has been resolved now, resulted from a failure of the Verizon Web app to check that a number entered into the app actually belonged to the user who was entering it. After entering the number, a user could then download a spreadsheet file of the SMS activity on a target account. Cody Collier, the researcher who discovered the vulnerability, said he decided right away to report it to Verizon because he is a Verizon customer and didn’t want others to have access to his account information. ‘I am a Verizon Wireless customer myself, so upon finding this, I immediately looked for a way to contact Verizon. I wouldn’t want my account information to exposed in such way, ‘ Collier said via email.” Read more of this story at Slashdot.

Biological Clock Discovered That Measures Ages of Most Human Tissues

starr802 writes “A biological clock capable of determining how old different human tissues and cells are has been discovered by a team of researchers from the University of California Los Angeles (abstract). ‘To fight aging, we first need an objective way of measuring it. Pinpointing a set of biomarkers that keeps time throughout the body has been a four-year challenge, ‘ Steve Horvath, a professor of human genetics at the David Geffen School of Medicine at UCLA and of biostatistics at the UCLA Fielding School of Public Health said in a statement. ‘My goal in inventing this clock is to help scientists improve their understanding of what speeds up and slows down the human aging process.'” Read more of this story at Slashdot.

British NHS May Soon No Longer Offer Free Care

An anonymous reader writes “Coinciding with challenges in the rollout of the U.S. Affordable Care Act are challenges for NHS. The Independent reports, ‘A National Health Service free at the point of use will soon be “unsustainable, ” if the political parties do not come forward with radical plans for change before the 2015 election, top health officials have warned. Stagnant health spending combined with ever rising costs and demand mean the NHS is facing “the most challenging period in its 65-year existence, ” the NHS Confederation said … In a frank assessment of the dangers faced by the health service, senior officials at the confederation say that the two years following the next general election will be pivotal in deciding whether the NHS can continue to provide free health care for all patients. “Treasury funding for the service will be at best level in real terms, ” they write. “Given that demand continues to rise, drugs cost more, and NHS inflation is higher than general inflation, the NHS is facing a funding gap estimated at up to £30bn by 2020.”‘ From The Guardian: ‘Our rose-tinted view of the NHS has to change.’ More at the Independent, Mirror, and Telegraph.” Read more of this story at Slashdot.

Snapchat Search Warrants Emphasize Data Vulnerability

Nerval’s Lobster writes “This year’s revelations about NSA surveillance have upended the idea that our data—any of it—is truly secure from prying eyes. That uncertainty has sparked the rise of several businesses with a simple proposition: you can send whatever you want via their online service (text, images, video), and that data will vaporize within seconds of the recipient opening it up. One of the most popular of those services is Snapchat, which allows users to take “Snaps” (i.e., videos or photos) that self-destruct a few seconds after the recipient opens them; that data also disappears from the company’s servers. But is ‘disappearing’ data truly secure from prying eyes? Earlier this week, Snapchat admitted to a loophole in its schema that leaves Snaps open to viewing by law enforcement — provided the latter shows up at the company’s front door with a warrant. Until a recipient opens a Snap, it’s stored in the company’s datacenter. In theory, law enforcement could request that Snapchat send it an unopened Snap. ‘If we receive a search warrant from law enforcement for the contents of Snaps and those Snaps are still on our servers, ‘ read an Oct. 14 posting on Snapchat’s corporate blog, ‘a federal law called the Electronic Communications Privacy Act (ECPA) obliges us to produce the Snaps to the requesting law enforcement agency.’ Law-enforcement entities have hit Snapchat with ‘about a dozen’ search warrants for unopened Snaps since May 2013. ‘Law enforcement requests sometimes require us to preserve Snaps for a time, like when law enforcement is determining whether to issue a search warrant for Snaps, ‘ the blog continued. That surveillance could also go beyond unopened Snaps: Snapchat ‘Stories, ‘ or a cluster of Snaps, live on the company’s servers for up to 24 hours and can be viewed multiple times, which broadens the window for law enforcement to poke its way in.” Read more of this story at Slashdot.

Ethernet’s 400-Gigabit Challenge Is a Good Problem To Have

alphadogg writes “As it embarks on what’s likely to be a long journey to its next big increase in speed, Ethernet is in some ways a victim of its own success. Years ago, birthing a new generation of Ethernet was relatively straightforward: Enterprises wanted faster LANs, vendors figured out ways to achieve that throughput and hashed out a standard, and IT shops bought the speed boost with their next computers and switches. Now it’s more complicated, with carriers, Web 2.0 giants, cloud providers, and enterprises all looking for different speeds and interfaces, some more urgently than others. … That’s what the IEEE 802.3 400Gbps Study Group faces as it tries to write the next chapter in Ethernet’s history. … ‘You have a lot of different people coming in to the study group, ‘ said John D’Ambrosia, the group’s chair, in an interview at the Ethernet Alliance’s Technology Exploration Forum in Santa Clara, California, on Tuesday. That can make it harder to reach consensus, with 75 percent approval required to ratify a standard, he said.” Read more of this story at Slashdot.
