Facebook Goes DRAM

Facebook has come up with a data cache which runs on flash memory instead of DRAM. Dubbed McDipper it saves money while still delivering higher performance than disk.

The system is a Facebook-built implementation of the popular memcached key-value store the only difference is that runs on flash memory rather than pricier DRAM. Memcached is the open-source key-value store that caches frequently accessed data in memory so applications can access and serve it faster than if it were stored on hard disks.

Facebook runs thousands of memcached servers to power its various applications. The only downside is that it is expensive. McDipper can handle working sets that had very large footprints but moderate to low request rates. It provides up to 20 times the capacity per server and still supports tens of thousands of operations per second.

According to Gigaom, Facebook has deployed McDipper for a handful of these workloads. This has reduced the total number of deployed servers in some pools by as much as 90 per cent while still delivering more than 90 per cent of get responses with sub-millisecond latencies.

Toshiba To Offer A 20-megapixel Image Chip

Toshiba is gearing up for to offer a 20-megapixel image sensor for digital cameras that it says will be the highest resolution of its kind.

The Tokyo-based firm said the new chips will be able to support capturing 30 frames per second at full resolution. They will also be able to shoot video at 60 frames per second at 1080P or 100 frames at 720P.

Toshiba said it will begin shipping samples of the new CMOS chips in January, with mass production to begin in August of 300,000 units monthly. Toshiba is best known in components for its NAND flash memory, which it develops with partner SanDisk, but is also a major manufacturer of LSI and other semiconductors.

Digital point-and-shoot cameras are steadily falling in price, squeezed between brutal competition among manufacturers and the increasing threat of smartphones and mobile devices. While the number of pixels a camera can capture is not always a direct measure of the overall quality of its images, it is a key selling point to consumers.

The image resolution of top-end smartphones now often meets or exceed that of digital cameras. The Nokia 808 PureView launched earlier this year has a 41-megapixel image sensor.

The Japanese manufacturer said it has increased the amount of information pixels in the new chip can store compared to its previous generation of CMOS, producing better overall images. It has also reduces the size of pixels – the new 20-megapixel version has individual pixels that measure 1.2 micrometers, down from 1.34 micrometers in its 16-megapixel product.

Baidu Heads To The Cloud

China’s largest search engine Baidu said on Monday that they would provide 30GB of free cloud storage to Android devices built with certain Qualcomm chips, in what’s the latest move by the company to build a presence in the country’s mobile services sector.

Baidu’s limited-time offer applies in China to two of Qualcomm’s latest chips, the Snapdragon S4 MSM 8×25 processor, and the Snapdragon S4 MSM 8x25Q processor. Users activating Baidu’s cloud service will receive 15GB of free cloud storage over the device’s lifetime, and an additional 15GB of storage free for one year.

As of Monday phones containing the chips, from Chinese manufacturers including Lenovo and Huawei, will ship with the free Baidu cloud storage enabled as a result of the partnership with Qualcomm.

Baidu is offering the free storage after the company in September declared China’s mobile Internet space as its next major focus, and announced a $1.6 billion investment to build a new cloud computing center.

Adobe Gives Up On Windows XP

Adobe said today that the current CS6 version of Photoshop will be the last one to support the operating system.

Adobe Product Manager Tom Hogarty said in a blog post that the Photoshop team would like to provide advanced notice that Photoshop CS6 (13.0) will be the last major version of Photoshop to support Windows XP. He said that modern performance-sensitive software requires modern hardware graphics interfaces that Windows XP lacks, in particular a way to tap into the power of GPUs. By only working on newer operating systems and hardware Adobe can bring in significantly better performance.

Photoshop CS6 already demonstrates that relying on a modern operating system, graphics cards/GPUs and graphics drivers can lead to substantial improvements in 3D, Blur Gallery and Lighting Effect features not available to Windows XP customers, he said.

Adobe hopes that by providing this information early it will help you understand our current decisions around operating system support and where we we’re headed with future releases of Photoshop. It is hard to see how any serious user of Adobe products could be using an XP machine anyway. The move away from XP started with CS 5 which only ran on Vista.

Google Acquires Instagram’s Rival

Google Inc said it purchased Instagram rival Nik Software, which makes award-winning photo editing application Snapseed, for an undisclosed amount.

Google and Facebook Inc are locked in a battle for social network followers that has increasingly shifted to mobile applications, such as photo editing.

While not as famous as Instagram, available for free on Apple’s mobile devices, Snapseed has won a following for its editing prowess among photographers, despite a $4.99 price tag.

Nik Software says Snapseed has more than 9 million users while Instagram says it has more than 100 million.

“We want to help our users create photos they absolutely love, and in our experience Nik does this better than anyone,” Vic Gundotra, Google’s senior vice president, engineering, said on a Google+ post.

Facebook this year bought Instagram, which made an app for users to add filters and effects to pictures taken on their smartphones, for a cool $1 billion.

“Google’s playing chase up in social,” BGC Partners analyst Colin Gillis said. “It’s yet another tuck in they have done, trying to boost their Google+ offering.”

Snapseed won Apple Inc’s “iPad App Of The Year” award in 2011 for its multitouch photo editing interface.

“We’ve always aspired to share our passion for photography with everyone, and with Google’s support we hope to be able to help many millions more people create awesome pictures,” Nik Software said on its Website.

Google’s Gundotra also said that Google+ had hit over 400 million users this week and had just crossed 100 million

Google Tweaks It’s Search Engine

Google is changing the way it handles searches in the United States to give users quick access to answers without leaving the page, the company said.

The new search process is based on what Google calls the “knowledge graph” — meaning that it tries to pinpoint faster the context surrounding its users’ keyword searches.

“Over the years, as search has improved, people expect more,” said Amit Singhal, vice president of engineering at Google and the head of search, in an interview. “We see this as the next big improvement in search relevance.”

The redesign, which for now affects only U.S.-based English language users, is gradually being rolled starting Wednesday on desktop, mobile and tablet platforms. Google plans to eventually expand the new search features outside the U.S., Singhal said, without specifying when.

Many of the results will carry more graphical elements, compared to standard lists of search results, such as maps and pictures of related results, often in separate pop-ups. The idea is to let users easily discover what related material interests them and click through to it, Singhal said.

Galaxy Nexus 4G LTE Finally On Sale

Verizon Wireless finally announced that the Samsung Galaxy Nexus smartphone running Android 4.0 on its 4G LTE network will be available on Thursday in stores and online for $299.99 with a two-year agreement.

The announcement, which came late Wednesday, arrived after days of speculation that the phone was being delayed over a dispute between the carrier and Google over the Google Wallet application, which doesn’t work on Verizon’s version.

During the period many expected Verizon to release the Galaxy Nexus, problems with the carrier’s LTE network arose for nearly two days, pushing LTE users to Verizon’s slower 3G service.

But Verizon never admitted there was any delay in releasing the device and pointed out that it had never given an official release date until Wednesday.

Verizon will carry a 4G LTE version that supports download speeds of up to 12Mbps. Online sales were set to start at 1 a.m. ET Thursday.

The new device has many features putting it at the top of the market for competing smartphones, including one of the highest prices: $299.99. Many rivals are priced at $200 or $250 on other U.S. carriers.

Websites ‘Leaking’ User Info To Other Firms

Many top websites share their visitors’ names, usernames or other personal information with their partners without alerting users and, in some cases, without knowing they’re doing it, according to a new study from Stanford University.

Many websites “leak” usernames to third-party advertising networks by including usernames in URLs that the ad networks can see in referrer headers, said the study, released Tuesday by Stanford Law School’s Center for Internet and Society. While there’s a debate in legal circles whether usernames are personal information, there’s a growing consensus among computer scientists that Web-based companies can use usernames to identify their owners, said Jonathan Mayer, a Stanford graduate student who led the study.

“The vast majority of usernames are unique,” he said. “Given the prevalence of social networking, often times, once you have a username for a social network, you then also have a person’s real name, possibly a photo, possibly more.”

Other websites share first names, email addresses and other information with advertising or other partners, Mayer said at a privacy conference in Washington. Those identifiers “get associated not just with what you’re doing right now, but get associated with what you’ve done in the past, and what Web browsing activity you may have in the future,” he said.

RIM To Launch Music Service

BlackBerry maker Research In Motion is making plans to roll out its own music streaming service that will work across its mobile devices, according to people familiar with the plans.

The new service is likely part of an attempt by RIM to improve its BlackBerry Messenger service as it competes with the mobile media platform strengths of rival Apple Inc and Google Inc’s Android.

RIM is in late-stage negotiations with major labels, including Vivendi SA’s Universal Music Group, Sony Corp’s Sony Music, Warner Music Group and EMI Group. The new service is expected to be announced by Labor Day in the United States, September 5.

RIM has been enhancing its BlackBerry Messenger offering, popularly known as BBM, since announcing its “social platform” at last September’s DevCon event where it unveiled the PlayBook tablet computer.

A RIM spokeswoman declined comment on the report but said BBM is one of the largest mobile social networks in the world.

RIM’s BlackBerry smartphones have been hit by a sharply declining market share in the United States, even as the company has expanded sales in other parts of the world, partly because of BBM’s popularity.

Analyst Matthew Thornton at Avian Securities said he doubted the music service would attract new users but might help the company keep its existing BlackBerry customers interested.

“I just don’t think trying to replicate Apple is really going to change their situation near term,” he said.

“For RIM it’s going to be the new OS 7 product first and foremost … and then it’s about QNX and making that transition.”

RIM has just launched an updated operating system on three new touchscreen devices intended to catch up with the technical specifications of Android and other rivals. The company plans to launch the first BlackBerrys using the QNX software, used on its PlayBook tablet, early next year.

Does Linkedin Share User Data?

Linkedin has upset many of its 100 million users by opting them into a programme that reveals their personal details to advertisers without telling anyone about it.

Linkedin changed its privacy policy to allow it to display the names and pictures of users with ads. The system works by showing friends and colleagues who’ve followed a brand name, effectively making them an unwitting salesperson for that brand, since people are more likely to click such advertisements on the basis that it looks like someone they know is recommending them. In reality, the other person has no idea that their photo and name are being used to sell things.

It’s a clever approach to advertising, but an absolutely abyssmal approach to privacy, as Linkedin has decided to automatically opt-in all of its users without informing them of the change.

Users can opt out if they want, but the option is buried in the Settings page, a ploy similar to that used by Facebook to hide its privacy settings. The big problem here is that if users don’t know that their name and photo are being used in this way, then how can they opt out of it?

Linkedin could face legal trouble for this decision. Digital Trends reports it is likely that Linkedin broke Dutch privacy law, which requires user consent for employing user images with advertisements. It could also be brought up before the European Commission and the UK Information Commissioner’s Office (ICO).
