Red Hat Strips Down For Docker 33

Posted by timothy
from the wearing-or-not-wearing-dockers dept.
angry tapir writes Reacting to the surging popularity of the Docker virtualization technology, Red Hat has customized a version of its Linux distribution to run Docker containers. The Red Hat Enterprise Linux 7 Atomic Host strips away all the utilities residing in the stock distribution of Red Hat Enterprise Linux (RHEL) that aren't needed to run Docker containers. Removing unneeded components saves on storage space, and reduces the time needed for updating and booting up. It also provides fewer potential entry points for attackers. (Product page is here.)

from the a-challenger-appears dept.
MojoKid writes: NVIDIA held an event in San Francisco last night at GDC, where the company unveiled a new Android TV streamer, game console, and supercomputer, as NVIDIA's Jen Hsun Huang calls it, all wrapped up in a single, ultra-slim device called NVIDIA SHIELD. The SHIELD console is powered by the NVIDIA Tegra X1 SoC with 3GB of RAM, 16GB of storage, Gig-E and 802.11ac 2x2 MIMO WiFi. It's also 4K Ultra-HD Ready with 4K playback and capture up to 60 fps (VP9, H265, H264) with encode/decode with full hardware processing. The company claims the console provides twice the performance of an Xbox 360. NVIDIA demo'ed the device with Android TV, streaming music and HD movies and browsing social media. The device can stream games from a GeForce powered PC to your television or from NVIDIA's GRID cloud gaming service, just like previous NVIDIA SHIELD devices. Native Android games will also run on the SHIELD console. NVIDIA's plan is to offer a wide array of native Android titles in the SHIELD store, as well as leverage the company's relationships with game developers to bring top titles to GRID. The device was shown playing Gearbox's Borderlands The Pre-Sequel, Doom 3 BFG Edition, Metal Gear Solid V, the Unreal Engine 4 Infiltrator demo and yes, even Crysis 3.

Google Backs Off Default Encryption on New Android Lollilop Devices 119

Posted by Soulskill
from the give-the-people-what-the-government-wants dept.
An anonymous reader writes: Although Google announced in September 2014 that Android 5.0 Lollipop would require full-disk encryption by default in new cell phones, Ars Technica has found otherwise in recently-released 2nd-gen Moto E and Galaxy S6. It turns out, according to the latest version of the Android Compatibility Definition document (PDF), full-disk encryption is currently only "very strongly recommended" in anticipation of mandatory encryption requirements in the future. The moral of the story is: don't be lazy — check that your full-disk encryption is actually enabled.

Police Could Charge Data Center Operators In the Largest Child Porn Bust Ever 199

from the enforcing-due-diligence dept.
sarahnaomi sends this report from Motherboard: Canadian police say they've uncovered a massive online file sharing network for exploitative material that could involve up to 7,500 users in nearly 100 countries worldwide. But unlike past investigations into the distribution of child porn, which typically involve targeting suspects individually, police have instead seized over 1.2 petabytes of data ... from a data center responsible for storing the material, and may even attempt to lay criminal charges against its operators, too.

"What we are alleging is occurring is that there are individuals and organizations that are profiting from the storage and the exchange of child sexual exploitation material," Scott Tod, Deputy Commissioner of the Ontario Provincial Police (OPP), told Motherboard at a conference late last month, after speaking to a crowd of defense specialists. "They store it and they provide a secure website that you can log into, much like people do with illegal online gaming sites."

New Seagate Shingled Hard Drive Teardown 93

Posted by Soulskill
from the made-out-of-actual-shingles dept.
New submitter Peter Desnoyers writes: Shingled Magnetic Recording (SMR) drives are starting to hit the market, promising larger drives without heroic (and expensive) measures such as helium fill, but at a cost — data can no longer be over-written in place, requiring SSD-like algorithms to handle random writes.

At the USENIX File and Storage Technologies conference in February, researchers from Northeastern University (disclaimer — I'm one of them) dissected shingled drive performance both figuratively and literally, using both micro-benchmarks and a window cut in the drive to uncover the secrets of Seagate's first line of publicly-available SMR drives.

TL;DR: It's a pretty good desktop drive — with write cache enabled (the default for non-server setups) and an intermittent workload it performs quite well, handling bursts of random writes (up to a few tens of GB total) far faster than a conventional drive — but only if it has long powered-on idle periods for garbage collection. Reads and large writes run at about the same speed as on a conventional drive, and at $280 it costs less than a pair of decent 4TB drives. For heavily-loaded server applications, though, you might want to wait for the next generation. Here are a couple videos (in 16x slow motion) showing the drive in action — sequential read after deliberately fragmenting the drive, and a few thousand random writes.

Ask Slashdot: How Does One Verify Hard Drive Firmware? 323

Posted by Soulskill
from the very-carefully dept.
An anonymous reader writes: In light of recent revelations from Kaspersky Labs about the Equation Group and persistent hard drive malware, I was curious about how easy it might be to verify my own system's drives to see if they were infected. I have no real reason to think they would be, but I was dismayed by the total lack of tools to independently verify such a thing. For instance, Seagate's firmware download pages provide files with no external hash, something Linux distributions do for all of their packages. Neither do they seem to provide a utility to read off the current firmware from a drive and verify its integrity.

Are there any utilities to do such a thing? Why don't these companies provide verification software to users? Has anyone compiled and posted a public list of known-good firmware hashes for the major hard drive vendors and models? This seems to be a critical hole in PC security. I did contact Seagate support asking for hashes of their latest firmware; I got a response stating, "...If you download the firmware directly from our website there is no risk on the file be tampered with." (Their phrasing, not mine.) Methinks somebody hasn't been keeping up with world events lately.

Under US Pressure, PayPal Stops Working With Mega 136

Posted by Soulskill
from the you-wouldn't-download-a-car dept.
New submitter seoras sends news that PayPal is now refusing to handle payments for Mega, Kim Dotcom's cloud storage service. A report (PDF) issued in September of last year claimed Mega and other "cyberlocker" sites made a great deal of illicit money off piracy. Mega disputes this, of course, and says the report caused U.S. Senator Patrick Leahy to pressure credit card companies to stop working with Mega. Those companies then pressured PayPal to stop as well. The hosting company claims, "MEGA provided extensive statistics and other evidence showing that MEGA’s business is legitimate and legally compliant. After discussions that appeared to satisfy PayPal’s queries, MEGA authorised PayPal to share that material with Visa and MasterCard. Eventually PayPal made a non-negotiable decision to immediately terminate services to MEGA."

An anonymous reader writes: Smartflash LLC has won a patent lawsuit against Apple over DRM and technology relating to the storage of downloaded songs, games, and videos on iTunes. Apple must now pay $532.9 million in damages. An Apple spokesperson did not hesitate to imply Smartflash is a patent troll: "Smartflash makes no products, has no employees, creates no jobs, has no U.S. presence, and is exploiting our patent system to seek royalties for technology Apple invented. We refused to pay off this company for the ideas our employees spent years innovating and unfortunately we have been left with no choice but to take this fight up through the court system." The trial happened in the same court that decided Apple owed VirnetX $368 million over FaceTime-related patents back in 2012.

Apple To Invest $2B Building Green Data Centers In Ireland and Denmark 82

Posted by samzenpus
from the going-green dept.
stephendavion writes Amid deeper investigations into how Apple may be using its operations in Ireland as a means for tax avoidance on tens of billions of dollars in profit, the iPhone maker has announced that it will spend nearly $2 billion (€1.7 billion) to develop two new 100% renewable energy data centers in Europe. The centers — which will use wind power and other green fuel sources — will be located in Athenry, Ireland, and Viborg, Denmark. Apple said that they will power services such as apps in the App Store, Siri and iMessage. Both locations will run on 100 percent renewable energy and Apple said they will have the 'lowest environmental impact' of its data centers thus far. It will also be following in the footsteps of companies like Facebook, which has also built sustainable data center operations out in Europe.

jones_supa (887896) writes "Canonical, through John Zannos, VP Cloud Alliances, has proudly announced that the first ever Microsoft Azure hosted service will be powered by Ubuntu Linux. This piece of news comes from the Strata + Hadoop World Conference, which takes place this week in California. The fact of the matter is that the news came from Microsoft who announced the preview of Azure HDInsight (an Apache Hadoop-based hosted service) on Ubuntu clusters yesterday at the said event. This is definitely great news for Canonical, as their operating system is getting recognized for being extremely reliable when handling Big Data. Ubuntu is now the leading cloud and scale-out Linux-based operating system."

Samsung's Portable SSD T1 Tested 105

Posted by samzenpus
from the where-the-rubber-hits-the-road dept.
MojoKid writes The bulk of today's high-capacity external storage devices still rely on mechanical hard disk drives with spinning media and other delicate parts. Solid state drives are much faster and less susceptible to damage from vibration, of course. That being the case, Samsung saw an opportunity to capitalize on a market segment that hasn't seen enough development it seems--external SSDs. There are already external storage devices that use full-sized SSDs, but Samsung's new Portable SSD T1 is more akin to a thumb drive, only a little wider and typically much faster. Utilizing Samsung's 3D Vertical NAND (V-NAND) technology and a SuperSpeed USB 3.0 interface, the Portable SSD T1 redlines at up to 450MB/s when reading or writing data sequentially, claims Samsung. For random read and write activities, Samsung rates the drive at up to 8,000 IOPS and 21,000 IOPS, respectively. Pricing is more in-line with high-performance standalone SSDs, with this 1TB model reviewed here arriving at about $579. In testing, the drive did live up to its performance and bandwidth claims as well.

Storing Data In Synthetic Fossils 36

Posted by Soulskill
from the worked-for-the-dinosaurs dept.
Bismillah tips news of research from ETH Zurich which brings the possibility of extremely long-term data storage. The scientists encoded data in DNA, a young but established technique that has a major problem: accuracy. "[E]ven a short period of time presents a problem in terms of the margin of error, as mistakes occur in the writing and reading of the DNA. Over the longer term, DNA can change significantly as it reacts chemically with the environment, thus presenting an obstacle to long-term storage." To get around this issue, they encapsulated the DNA within tiny silica spheres, a process roughly comparable to the fossilization of bones (abstract). The researchers say data can be preserved this way for over a million years.

Vint Cerf Warns Against 'Digital Dark Age' 166

from the strangely-silent-on-digital-bronze-age dept.
An anonymous reader writes: Vint Cerf, speaking at the American Association for the Advancement of Science, said we need better methods for preserving everything we do on computers. It's not just about finding better storage media — it's about recording all the aspects of modern software and operating systems so future generations can figure out how it all worked. Cerf says, "The solution is to take an X-ray snapshot of the content and the application and the operating system together, with a description of the machine that it runs on, and preserve that for long periods of time. And that digital snapshot will recreate the past in the future." Cerf is also pushing for better data preservation standards: "The key here is when you move those bits from one place to another, that you still know how to unpack them to correctly interpret the different parts. That is all achievable if we standardize the descriptions."

Ask Slashdot: With Whom Do You Entrust Your Long Term Data? 178

Posted by Soulskill
from the in-cloud-we-trust dept.
jppiiroinen writes: F-Secure, a company based in Finland, has sold its cloud storage business to a U.S. company (Synchronoss Technologies, Inc) speculated to have ties to the NSA. In previous, public announcements, they used arguments equivalent to, "trust us, your data will be safe." Now, it's likely F-Secure simply realized that competing against the big players, such as Google and Dropbox, didn't make much sense.

But it makes me wonder: Whom do you trust with your data? And who really owns it? What about in 3-6 years from now? How should I make sure that I retain access to today's data 20 years from now? Is storing things locally even a reasonable option for most people? I have a lot of floppies and old IDE disks from the 90s around here, but no means to access them, and some of the CDs and DVDs has gone bad as well.

IT Vision Technology (ITVT) CEO Jochen Klipfel says: 'We developed a solution that reduces the oxygen content in the air, so that even matches go outIt took us two years'. ITVT have the European Air Force among its customers, so security is an even higher priority than in the average DC build; the refurbished bunker has walls 11 feet thick and the central complex is buried twenty feet under the earth.

Proposed Disk Array With 99.999% Availablity For 4 Years, Sans Maintenance 258

Posted by timothy
from the with-enough-disks-all-rooms-are-full dept.
Thorfinn.au writes with this paper from four researchers (Jehan-François Pâris, Ahmed Amer, Darrell D. E. Long, and Thomas Schwarz, S. J.), with an interesting approach to long-term, fault-tolerant storage: As the prices of magnetic storage continue to decrease, the cost of replacing failed disks becomes increasingly dominated by the cost of the service call itself. We propose to eliminate these calls by building disk arrays that contain enough spare disks to operate without any human intervention during their whole lifetime. To evaluate the feasibility of this approach, we have simulated the behaviour of two-dimensional disk arrays with N parity disks and N(N – 1)/2 data disks under realistic failure and repair assumptions. Our conclusion is that having N(N + 1)/2 spare disks is more than enough to achieve a 99.999 percent probability of not losing data over four years. We observe that the same objectives cannot be reached with RAID level 6 organizations and would require RAID stripes that could tolerate triple disk failures.

Why Coding Is Not the New Literacy 212

Posted by Soulskill
from the pants-are-the-new-shirts dept.
An anonymous reader writes: There has been a furious effort over the past few years to bring the teaching of programming into the core academic curricula. Enthusiasts have been quick to take up the motto: "Coding is the new literacy!" But long-time developer Chris Granger argues that this is not the case: "When we say that coding is the new literacy, we're arguing that wielding a pencil and paper is the old one. Coding, like writing, is a mechanical act. All we've done is upgrade the storage medium. ... Reading and writing gave us external and distributable storage. Coding gives us external and distributable computation. It allows us to offload the thinking we have to do in order to execute some process. To achieve this, it seems like all we need is to show people how to give the computer instructions, but that's teaching people how to put words on the page. We need the equivalent of composition, the skill that allows us to think about how things are computed."

He further suggests that if anything, the "new" literacy should be modeling — the ability to create a representation of a system that can be explored or used. "Defining a system or process requires breaking it down into pieces and defining those, which can then be broken down further. It is a process that helps acknowledge and remove ambiguity and it is the most important aspect of teaching people to model. In breaking parts down we can take something overwhelmingly complex and frame it in terms that we understand and actions we know how to do."

Data Encryption On the Rise In the Cloud and Mobile 83

Posted by Soulskill
from the setting-a-standard dept.
dkatana writes: Overall, demand for encryption is growing. Cloud encryption services provider CipherCloud recently received a $50 million investment by Deutsche Telekom, which the company said positions it for "explosive growth" this year. The services are designed to allow corporations to benefit from the cost savings and elasticity of cloud-based data storage, while ensuring that sensitive information is protected.

Now, both Apple and Google are providing full encryption as a default option on their mobile operating systems with an encryption scheme they are not able to break themselves, since they don't hold the necessary keys.

Some corporations have gone as far as turning to "zero-knowledge" services, usually located in countries such as Switzerland. These services pledge that they have no means to unlock the information once the customer has entered the unique encryption keys. This zero-knowledge approach is welcomed by users, who are reassured that their information is impossible to retrieve — at least theoretically — without their knowledge and the keys.
