Lenovo has added three ThinkCentre desktop PCs to its stable of business devices this week. The three devices span the range of desktops, with the ThinkCentre E63z being an All-In-One, the ThinkCentre M53 being classified as a “tiny” desktop, and the ThinkCentre M79 offering the more traditional Small Form Factor (SFF) and Mini Tower models.

 

ThinkCentre M79 Mini Tower

The typical office PC is likely a Mini Tower or SFF desktop, and the ThinkCentre M79 is an AMD A-Series APU equipped desktop offering optional Solid State Drive (SSD) or Solid State Hybrid Drive (SSHD) storage options in the SFF or Mini Tower configurations. Many businesses have moved to dual-displays for their desktop workers, and the M79 supports that out of the box, but also offers an optional second DisplayPort connector for those that want to move up to three displays. As a business PC, it also employs the Trusted Platform Module (TPM) version 1.2 for enhanced security feature support such as Bitlocker. It also includes version 3.0 of the Lenovo Intelligent Cooling Engine which controls the desktop acoustics and temperatures.  Also of benefit to the business crowd, the M79 has a 15 month guaranteed hardware cycle to allow for an easier time managing system images. The ThinkCentre M79 is available now starting at $449.

The micro desktops from Lenovo have been around for a while, and the latest model to join the group is the ThinkCentre M53. Though larger than the NUC, the M53 is still extremely compact at 7.2” x 7.16” x 2.5” and can be vertically or horizontally arranged or can be mounted on the back of a monitor with VESA mounting holes on the underside of the device. The M53 shares accessories and power connectors with the other “tiny” computers from Lenovo which is always appreciated. The ThinkCentre M53 is available soon with a starting price of $439.

ThinkCentre E63z All-In-One

The final business aimed desktop is an all-in-one device called the ThinkCentre E63z. This unit features an integrated 19.5” display with optional touch, and an integrated camera and stereo speakers to allow for voice over IP and other collaboration software usage. Models equipped with the optional Core i3 CPU include an additional HDMI port, a card reader, and a Rapid Charge USB port for charging mobile devices. The E63z is available now starting at $479, with the Core i3 models available later this year.

We do not have a full list of specifications for these devices at this time, but those should be available on the Lenovo site when they devices are made for sale.

Much like the recent swathe of X99 motherboard previews we have seen, memory manufacturers are getting on board with showcasing their DDR4 memory modules to use with the Haswell-E platform. Unlike the CPUs from Intel, there is no formal NDA as such, allowing the media to report the design and specifications, although because real-world performance requires the CPU, no-one is able to post benchmark numbers.

The new DDR4 from G.Skill is the next DRAM module manufacturer to come out with an official press release, and following the previous high performance Ripjaws DDR3 range G.Skill will introduce its memory under the Ripjaws 4 moniker with a new heatspreader design.

G.Skill’s press release confirms the voltage ranges for DDR4, with 1.2 volts being standard on 2133 MHz to 2800 MHz kits, with the higher performance modules at ≥3000 MHz and above requiring 1.35V. The product line that G.Skill is aiming to release at launch is quite impressive with all the 1.2 volt modules in 16GB, 32GB and 64 GB kits. Due to the extra binning and higher tolerances of the more performance oriented kits, the DDR4-3000 C15 will be in 16GB or 32GB kits, DDR4-3000 C16 will be in a kit 32GB and the top line 3200 MHz C16 will be in a 16GB kit only.

G.Skill is reporting full XMP 2.0 support, and that this new module design matches the 40mm height of previous Ripjaws designs, allowing previous CPU coolers to be matched with this generation. As the modules are launched, the three colors G.Skill is pursuing are blue, red and black. I know G.Skill monitors our news, so if you really want another color in there, make a note in the comments.

Preorder pricing puts these modules at:

DDR4-2133 C15 4x4GB: $260
DDR4-2400 C15 4x4GB: $280 / £240
DDR4-2666 C15 4x4GB: $300 / £290
DDR4-3000 C15 4x4GB: $400 / £380

DDR4-2133 C15 4x8GB: $480
DDR4-2400 C15 4x8GB: $530 / £440
DDR4-2666 C15 4x8GB: $550 / £500

On Thursday, 25-year-old Philip Danks was sentenced to 33 months in jail by a Wolverhampton judge for pirating a copy of Fast and Furious 6. Danks bragged that he was the first person in the world to seed the illicit recording, which he recorded from the back of a local cinema in May 2013. His upload was downloaded around 700,000 times.

The court also ruled that Michael Bell, the boyfriend of Danks' sister, played a part in distributing the film. He was sentenced to 120 hours of community service.

The film's distributor, Universal Pictures, argued to the judge that Danks' upload cost the company about £2.5 million. Danks had also sold DVD copies of the movie for £1.50 each. He said his total profit from the scheme was about £1,000.

Censorship of the Internet in China is a heavily studied but little-understood process, driven by both private networks and government employees and having effects that are hard to measure. To better understand it, a group of researchers tested censors and filters by attempting to post over a thousand bits of content on various social networking sites. They found that there was an aggressive pre-filtering process that holds a high number of submissions for review before they're posted—and that the results are actually undermining China's censorship mission. The filters tend to hamstring pro-government content as often as they block anti-government writing.

Part of the authors' process involved setting up a social media site of their own within China to see what standards they would be subjected to and what tools they would have to use in order to comply with the country's censorship requirements. They found that sites have an option to install automated review tools with a broad range of filter criteria. Censorship technology is decentralized, they wrote, which is a technique for "[promoting] innovation" in China.

Most research that has been done on Chinese censorship is largely based on what posts exist on the Internet at one point and then do not at a later time, indicating that they were pulled by censors. While that behavior is easily observed, there is another layer to the censorship system whereby users' posts get held for review by censors before they're made public. This new study attempted to figure out what sort of posts would get held for review, what would eventually make it through, and what might escape suspicion at either the posting or review stage, only to be removed later.

A new iPhone screen size doesn't come along every day—the last one happened in 2012, when the iPhone 4S (left) was replaced by the iPhone 5 (right). Jacqui Cheng

We're just a few weeks out from the expected launch of Apple's next iPhone, which means the ever-noisy rumor mill is spinning even more quickly than usual. Rather than bombarding you continuously every time a blurry picture of a circuit board leaks, we're going to gather up the most relevant stuff for your perusal, applying a healthy amount of skepticism along the way. This week, the scuttlebutt is about the phone's larger screen, which may be its most obvious and most widely anticipated feature.

Finding resolution This is supposedly a close-up shot of the new iPhone's display panel. Feld & Volk

First up, we have some rumors from earlier this week on the screen's resolution—Apple will want to hold on to the "Retina" moniker it's been using for its screens since the iPhone 4, and that means maintaining or beating the 326 PPI density of its current screens. One report, based on a close-up photo of what is supposedly an iPhone display panel, claims a resolution of 1704×960. Another, based on a string found in the latest Xcode 6 beta, claims a resolution of 1472×828.

The new iPhone is rumored to come in two different screen sizes, one 4.7-inch and one 5.5-inch. At 4.7 inches, those rumored resolutions would come out to 416 PPI and 359 PPI, respectively. At 5.5 inches, they would come out to 356 PPI and 307 PPI. Assuming that we do get two different iPhones in two different sizes, it's theoretically possible for both resolutions to be correct: the higher resolution might belong to the 5.5-inch model, while the lower resolution could apply to the 4.7-inch model. At this point there's not a lot of proof one way or the other.

At Flash Memory Summit, Toshiba was showcasing their latest 15nm 128Gbit MLC NAND wafer that has been developed in partnership with SanDisk. I simply could not resist to calculate the die size as Toshiba/SanDisk has not published it and die size is always the basis of any semiconductor cost analysis. Unfortunately I was too busy running between meetings that I did not take a photo of the wafer, so I am borrowing the picture from Custom PC Review.

To estimate the die size, I used the same method as with Samsung's second generation V-NAND. Basically I just calculated the amount of dies in both X and Y axes of the wafer as that gives as an approximation of the die size since we know that the diameter of the wafer is 300mm. 

The 15nm node from Toshiba/SanDisk is extremely competitive. Its bit density is essentially equivalent to Samsung's V-NAND, so it is no wonder that Toshiba and SanDisk are betting heavily on their 15nm node before moving to 3D in early 2016. Compared to other 2D NAND dies, the 15nm node is a clear winner from bit density standpoint as Micron's 16nm MLC does not even come close.

Toshiba's and SanDisk's secret lies in two-sided sense amp and all bit line (ABL) architecture, which reduce the size of the peripheral circuits and sense amplifier, resulting in higher memory array efficiency. Based on my estimation, the array efficiency (i.e. how big portion of the die is dedicated to memory cells) is about 80%, which is typical for a 128Gbit capacity. Higher capacities tend to yield better array efficiency since the peripheral circuitry does not scale as well as the memory cells do, so increasing the die capacity is one of the key solutions in lowering the cost per gigabyte.

Since nobody has yet taken a cross-section of the 15nm die, it is hard to say for sure what Toshiba and SanDisk are doing to shrink the dimensions. There is no mention of high-K dielectrics, so that seems unlikely and if history is any guidance, then Toshiba/SanDisk is simply increasing the aspect ratio by making the floating gate taller to compensate for the smaller feature size and keep the overall floating gate volume similar. That also helps to maintain the gate coupling ratio because the control gate is still wrapped around the floating gate and with a taller floating gate the capacitance between the gates should remain sufficient despite the increasing proximity of the floating gates. 

The production of Toshiba/SanDisk 15nm NAND node is currently ramping up and SSDs based on the new node are expected in Q4'14.

Earlier this year, a weak earnings report and wave of store closures had us thinking about the long, slow decline of brick-and-mortar game retail. Today, things look a little brighter, with GameStop reporting healthy sales growth along with an incredible factoid about its centrality to the modern console software market.

"Our hardware and software market share continues to expand and is now at an all time high as we go into the critical holiday season," GameStop President Tony Bartel said during an earnings call. “We continue to sell over one half of all PS4 and Xbox One titles.”

Let that sink in for a second: a single chain of gaming stores sells more individual Xbox One and PS4 games than all the big box stores, retail websites, and direct digital downloads combined. That doesn't sound like a business that's on the verge of collapse. Total, year-over-year sales growth of 25 percent for the quarter, including a 16 percent increase in new software sales, also sounds pretty healthy for GameStop.

Los Angeles County Sheriff's Department

The tale of an iPhone stolen from a burglarized Southern California home sits at the intersection of Web culture and the swap meet.

A woman in the Los Angeles suburb of Santa Clarita reported to authorities that her home had been ransacked July 30, and among the missing items were cash and an iPhone. But in what appeared to be another episode of Thieves Gone Stupid, the victim's iCloud account was hit with pictures, including a selfie of a cute couple posing on a pillow.

The Los Angeles County Sheriff's Department released the selfie days ago, saying that the unidentified people in the image were persons of interest. The story, with the couple's picture, went viral. On Thursday, the whodunit got even stranger. The man in the photo told NBC Los Angeles that neither he nor his girlfriend committed the burglary.

At this year’s Computex, I had the opportunity to sit down with Mrs. Shalley Chen, ADATA’s President, to discuss the current trends in the memory and SSD business, as well as get an overview of ADATA’s future plans. Mrs. Chen has been with ADATA since the company was founded in 2001 and is also the wife of the founder, Simon Chen. Before stepping in as President in April this year, Mrs. Chen served as an Executive Vice President. Mrs. Chen also holds a degree in business management from the Ming Chuan University in Taiwan.

Before we get into the actual interview, I want to provide a brief overview of ADATA. The company generates over $1 billion in yearly revenue, which makes ADATA one of the largest memory companies in the world.  Over a half of the revenue comes from the APAC (Asia-Pacific) region, which is logical given ADATA’s Taiwanese roots and the size of the Asian market. The North and Latin America region ranks as the second largest revenue source with about 15% share in total revenue, followed by Europe and other smaller regions. In the interview Mrs. Chen hinted that Asia, Europe and especially Russia are potential future growth areas for ADATA since the memory and SSD markets are still in a developing stage, whereas in the US the markets are more mature.

ADATA has had an office in the US since 2002 and employs 41 people across two offices in Los Angeles and Miami. These are both sales and customer support offices with the LA office in charge of North America while the Miami office is responsible for Latin America. All R&D is done in Taiwan at ADATA HQ whereas production is split between ADATA’s owned factories in China and Taiwan. While in Taiwan I took advantage of the offer to visit ADATA’s headquarters and the Taiwanese factory, as well as take some images for another article. Ever since the company was founded, ADATA has been a memory centric company. Like many companies of a similar nature, the mission, as it stood from day one, is to become the global leading brand of memory products. Although the product portfolio has grown over the years to include newer products such as USB flash drives, external hard drives, SSDs, memory cards, and, more recently, mobile power banks - fundamentally ADATA is still a memory company. Over half of ADATA’s revenue is generated by DRAM sales, and market researches rank ADATA as the Number Two DRAM module supplier in the world.

Given the high competition in the memory and SSD business, the question I always put to the manufacturers is this: what differentiates you from all the other brands? There are a dozen consumer focused DRAM companies, and there is little room for innovation or differentiation in the industry. Mrs. Chen told me that ADATA’s best weapon against the competition starts from the diversity of the product portfolio to the close relations with both chip suppliers and distributors. Mrs. Chen was keen to point out that ADATA makes products for all three major markets (client, enterprise and industrial), giving ADATA several different revenue sources, and the percentage of revenues from enterprise and industrial is getting bigger and bigger. This directly implies that the enterprise and industrial segments are substantial to ADATA.

Big enterprise OEMs like Intel and Samsung are typically interested only in large enterprises that buy upwards of tens of thousands of units, which leaves the small to medium size enterprise market to OEMs like ADATA to fight for the rest of the market. For example, some of Samsung’s enterprise products are only available to large OEMs (like EMC, Dell etc.), which leaves a niche for OEMs like ADATA and other smaller OEMs to offer better support for small to medium size enterprises. This also lends a benefit to work directly with the OEM for any customization.

Like other fabless DRAM and SSD manufacturers, ADATA does not manufacture the chips they use – ADATA have to buys them from the likes of Micron and Samsung. I asked if ADATA has ever thought about moving to chip fabrication, but the answer was negative. The main reason is the cost of a fab, and investing billions of dollars is a large risk. If we look at the major semiconductor fabricators, most of them have been in the industry for decades, developing new technologies as the research progresses. As a result, it would be extremely difficult for a new player to gain any significant market share without innovation or a wide product portfolio and mountains of investment (it is worth noting that innovation can come from start-ups that have new technology but get acquired). Another point ADATA raised is that it has close relations with DRAM and NAND suppliers, and thus has no need for a chip fab. In the end, the DRAM module industry is all about managing inventory against cost and potential sales, so the competitive advantage lies in forecasting the demand and managing the inventory efficiently.

The same applies to SSD controller development. Even though controllers can be fabricated by a third party, the capital required for the development and manufacturing is still a large sum. ADATA raised STEC as an example, which took the path to design its own controller platform but got into serious financial trouble due to the cost of the development.  STEC ended up being acquired by Western Digital. ADATA does, however, have its own SSD firmware development team that has been in action since 2007. ADATA believes that the firmware team will play a key role to ensure competitiveness in the future. At this point in time, the team is mainly focusing on industrial SSD firmware development but there will be a change towards more unique firmware in the consumer side as well.

One of the big topics at Computex was the state of DDR4, and ADATA was heavily presenting its DDR4 portfolio at the show. Given ADATA’s position, the company wants to be the leader in DDR4 and will aim to push the new technology quite aggressively to both consumers and enterprises. ADATA is one of Intel’s six Haswell-E/X99 launch partners (the others are Micron, Samsung, Hynix, Kingston and Crucial), so there should be plenty of ADATA DDR4 available when the X99 platform launches later this year.

I asked ADATA whether the market for DDR4 will any different from current DDR3 from an OEM perspective. Mrs. Chen replied that DDR4 is different in the sense that right now DDR4 is mostly an enterprise product and will be sold through B2B marketing. The enterprise segment, due to the demand of more units per sale, also gets a greater benefit from DDR4, which is due to the lower voltage and higher frequency. The stereotypical scenario of hundreds of racks with each server equipped with eight to sixty-four DIMMs or more, lower power consumption on one module adds up and is thus always welcome. The speed should help enterprise workloads due to the tendency to be more often bound by memory performance than client workloads.

For the end-users, ADATA showed us there will be branded products at retail as well, but until the mainstream platform adopts DDR4, the enterprise segment will be the main market. In terms of production, ADATA believes that DDR4 will overtake DDR3 in H1’15 for the enterprise market, but the same will not happen in the consumer side until sometime in 2016.

All in all, there is a lot going on in both DRAM and SSD industries at the moment, so it will be interesting to see how the market reacts. We would like to thank Mrs. Chen and ADATA for their time giving us the opportunity to discuss the DRAM and SSD markets. As part of my visit to ADATA, I also met with ADATA’s DRAM and SSD directors to discuss their technology at a lower level. Keep your eyes peeled for that article in due course.

When a British Ars reader went to delete his Ashley Madison account, this is what he saw.

Earlier this week, Ars got an e-mail from a reader named Rob Plant. “I think most right-thinking people have been dismayed by the tactics of charging for picture take downs—what is worrying to me is that these practices now seem to have been taken up by more legitimate websites.”

Ars has long covered the scourge of “revenge porn,” in which seedy websites post revealing photos of unwilling people and then charge those victims a fee to take the photos down. But Plant was writing about a site called Ashley Madison, which markets itself as a dating website for married people to find accomplices in extra-marital affairs. (Its slogan is blunt: “Life is short. Have an affair.”) The website has been around since 2001, and although it's taken some guff for allegations that it populates its network with fake profiles of women, it still boasts 29 million users worldwide, most of whom are presumably not fake.

The way it works is this: Ashley Madison allows people to sign up for free with "Guest" accounts, which permit users to send and receive photos and “winks.” Guest accounts can also reply to messages sent by a member. To become a "Full Member," one must buy credits, as opposed to, say, paying a monthly subscription. Full Members can initiate messages and chats with their credits, and women can send messages “collect." After first contact (and guidelines of the Prime Directive permitting) messages between the two users are free.

Daniel Genkin et al.

Researchers from Tel Aviv University have demonstrated an attack against the GnuPG encryption software that enables them to retrieve decryption keys by touching exposed metal parts of laptop computers.

There are several ways of attacking encryption systems. At one end of the spectrum, there are flaws and weaknesses in the algorithms themselves that make it easier than it should be to figure out the key to decrypt something. At the other end, there are flaws and weaknesses in human flesh and bones that make it easier than it should be to force someone to offer up the key to decrypt something.

In the middle are a range of attacks that don't depend on flaws on the encryption algorithms but rather in the way they've been implemented. Encryption systems, both software and hardware, can leak information about the keys being used in all sorts of indirect ways, such as the performance of the system's cache, or the time taken to perform encryption and decryption operations. Attacks using these indirect information leaks are known collectively as side channel attacks.

Yoav F On a mobile application, users typically have a single choice to protect their privacy: install the application or not.

The binary choice has left most users ignoring permission warnings and sacrificing personal data. Most applications aggressively eavesdrop on their users, from monitoring their online habits through the device identifier to tracking their movements in the real world via location information.

Now, a research group at North Carolina State University hopes to give the average user a third option. Dubbed NativeWrap, the technology allows Web pages to be wrapped in code and make them appear as a mobile application, but with user-controlled privacy. Because many applications just add a user interface around a Web application, the user should have equivalent functionality for many wrapped apps, said William Enck, assistant professor in the department of computer science at North Carolina State University.

A parasite queen (left) and the queen of the ants it preys on. Note the two scale bars both represent one millimeter, indicating the parasites' relatively small size. University of Rochester

We tend to think of parasites as creatures that attach themselves to their hosts or worm their way inside, consuming the hosts' resources directly from their bodies. But there are other parasites that steal from their hosts simply by freeloading off them. The classic example is the cuckoo, which lays eggs in the nests of other birds, who then happily feed the cuckoo's offspring as if they were their own.

A successful strategy like that is hard for evolution to pass up. So it really wasn't a surprise to find out that there are also parasitic species of ants, ones that breed within the nests of other ants and raise their offspring using the resources provided by the hosts. Now, researchers have developed evidence that at least one of those species evolved within the nests that they now occupy.

The parasitic ant in question has the evocative name Mycocepurus castrator. It lives off the hard work of a related leaf-cutter ant named Mycocepurus goeldii. Although the host species is distributed widely within South America, M. castrator has a much narrower range—a single stand of eucalyptus trees conveniently located on the campus of Sao Paulo State University in Brazil.

An IP address used by staff at the US House of Representatives has been banned from editing Wikipedia for 30 days. It's the second such punishment for would-be anonymous House Internet users in less than a month.

The first ban was imposed for 10 days after a series of "disruptive" edits, including a change to the entry about the website Mediaite to describe it as a "sexist transphobic news and opinion blog."

Now the same IP address has been condemned by editors for making several controversial edits on articles related to transgender issues. Last night, a Wikipedia administrator imposed a month-long ban, with some editors asking for harsher measures.

Left: Google's prototype car. Right: the eventual final design. Google

Traditionally, Google's self-driving car prototypes have taken existing cars from manufacturers like Toyota and Lexus and bolted on the self-driving car components. This is less than ideal, since it limits the design possibilities of the car's "vision" system and includes (eventually) unnecessary components, like a steering wheel and pedals.

However, Google recently built a self-driving car of its own design, which had no human control system other than a "go" button. The California DMV has now thrown a speed bump in Google's car design, though, in the form of new testing regulations that require in-development self-driving cars to allow a driver to take “immediate physical control” if needed.

The new law means Google's self-designed car will need to have a steering wheel and gas and brake pedals while it is still under development. According to The Wall Street Journal, Google will comply with the law by building a "small, temporary steering wheel and pedal system that drivers can use during testing" into the prototype cars. The report says California officials are working on rules for cars without a steering wheel and pedals, but for now, a human control system is mandatory.

Beta users will also get a new build of iTunes 12. Andrew Cunningham

Apple has just released the first update to the OS X Yosemite Public Beta, about a month after the first beta shipped. If you skipped the first beta but would like to give this one a try, Apple's sign-up page still appears to be accepting new testers (the company said that it would close the program down after the first million sign-ups, a number that apparently hasn't been hit yet).

The build number of the new beta indicates that it's roughly the same as Yosemite Developer Beta 6, which was released earlier this week to registered iOS and OS X developers. The first public beta was more or less identical to Developer Beta 4.

In the space of those two developer betas, Apple has been working to squash out bugs and has further Yosemite-ized more traditional OS X components. The volume and brightness overlays have been changed to match the frosted translucent look used elsewhere in the OS, and Apple added a new batch of Yosemite-themed wallpapers. Additional application and System Preferences icons have also been redesigned to match Yosemite's simpler, "flatter" look.
