Facebook speeds PHP by crafting a PHP virtual machine

Facebook speeds PHP by crafting a PHP virtual machine

Social networking giant Facebook has taken another step at making the PHP Web programming language run more quickly. The company has developed a PHP Virtual Machine that it says can execute the language as much as nine times as quickly as running PHP natively on large systems.

“Our goal is to make PHP run really, really quickly,” said Joel Pobar, a Facebook engineering manager. Facebook has been using the virtual machine, called the HipHop Virtual Machine (HHVM), across all of its servers since earlier this year.

Pobar discussed the virtual machine at the O’Reilly Open Source Conference (OSCON) being held this week in Portland, Oregon.

Shares its development tools

HHVM is not Facebook’s first foray into customizing PHP for faster use. PHP is aninterpreted language, meaning that the source code is executed by the processor directly. Generally speaking, programs written in interpreted languages such as PHP tend not to run as quickly as languages, such as C or C++, that have been compiled beforehand into machine language byte code. Facebook has remained loyal to PHP because it is widely understood by many of the Web programmers who work for the company.

To keep up with the insatiable user demand, however, Facebook originally devised a compiler, called HipHop, that would translate PHP code into C++, so it then it could be compiled ahead of time for faster performance.

While Facebook enjoyed considerable performance gains of this first version of HipHop for several years, it sought other ways to speed the delivery of the dynamically created Web pages to its billion or so users. “Our performance strategy for that was going to tap out,” Pobar admitted.

HHVM is the next step for Facebook. Under development for about three years, HHVM actually works on the same principle as the Java Virtual Machine (JVM). HHVM has a just-in-time (JIT) compiler that converts the human readable source code into machine-readable byte code when it is needed. (The previous HipHop, renamed HPHPc, has now been retired within Facebook.)

This JIT approach allows the virtual machine to “make smarter decisions at runtime,” Pobar said. For instance, if a call is made to the MySQL database to read a row of data, the HHVM can, on the fly, figure out what type of data it is, such as an integer or a string. It then can generate or call code on the fly that would be best suited for handling this particular type of data.

With the old HipHop, “the best it can do is analyze the entire Facebook codebase, reason about it and then specialize code based on its reasoning. But it can’t get all of the reasoning right. There are parts of the code base that you can not simply infer about or reason about,” Pobar said.

Virtual system speedier

Pobar estimated that HHVM is about twice as fast as HPHPc was, and about nine times as fast as running straight PHP.

Facebook has posted the code for HHVM on GitHub, with the hopes that others will use it to speed their PHP websites as well.

HHVM is optimized for handling very large, and heavily used, PHP codebases. Pobar reckoned that using HHVM for standard sized websites, such as one hosting a WordPress blog, would gain only about a fivefold performance improvement.

“If you take some PHP and run it in on HipHop, the CPU execution time [may] not be the limiting factor for performance. Chances are [the system is] spending too much time talking to the database or spending too time talking to [the] memcache” caching layer, Pobar said.

Facebook offers the dummy’s guide to mobile advertising

Facebook offers the dummy’s guide to mobile advertising

Facebook Inc’s mobile advertising success offers a ray of hope for Internet companies trying to make money within the confines of the smartphone’s small screen.

The social network’s 75 percent surge in mobile ad revenue in a span of just three months not only doused skepticism on Wall Street and Madison Avenue about Facebook’s business prospects, some say it could serve as a how-to guide for other Web companies navigating a world where the phone and tablet have fast become the screens of choice.

Facebook’s “Newsfeed” ads, which inject marketing messages straight into a user’s content stream and are tailored for mobile devices, were the stars behind the social network’s stunning numbers on Wednesday.

“You’re going to see a lot of companies transitioning and trying to emulate this model because it’s working so well. That’s why last night was a true watershed moment,” said Ben Schachter, an analyst at Macquarie Research.

Internet company executives have long been concerned that mobile advertising is inherently less lucrative than traditional desktop PC advertising, due to the smartphone’s limited screen size and possible consumer resistance to a flood of ads on their devices.

Companies from Google Inc and Yahoo Inc to upstarts such as Snapchat are searching for the right formula to monetize mobile services. While Google has developed a mobile ad business generating an estimated $10 billion a year in revenue, it remains much smaller and less lucrative than Google’s desktop search advertising. Analysts expect Google to generate $60 billion in annual revenue this year.

That wholesale exploration of “native ads” – or marketing messages intended to blend with a users’ personal content, rather than stand out as an ad – has met with varying success.

Twitter, which pioneered the concept of the in-stream ad even before Facebook, may also be well-positioned to benefit from mobile ads. “Sponsored” messages now pop up abruptly in the middle of streams of tweets, but analysts say the frequency is much lower on Facebook newsfeeds.

More than half of the privately held company’s revenue will come from mobile ads this year, reckons Clark Fredricksen, at industry research firm eMarketer.

Some are just getting into the game. This week, LinkedIn Corp, the network for business professionals, rolled out in-stream ads on mobile and PC versions of its service. Yahoo has experimented with similar types of ads, and acquired blogging hub Tumblr for $1.1 billion in May, in part to jumpstart efforts at developing new formats.

But it’s Facebook, which a year ago had zero mobile revenue, that has most aggressively promoted its mobile advertising business to Madison Avenue – with seeming success.

“Compared to other companies, nobody has come right out and said mobile is our sole focus now,” said Angela Steele, CEO of Ansible, part of advertising holding company IPG. “Facebook put all their eggs in one basket.”

FOLLOWING SUIT

One longstanding question has been how much tolerance consumers have for ads that disrupt their stream of content. Facebook said it has steadily increased the number of ads in the news stream without noticing a drop in user satisfaction.

Facebook Chief Executive Mark Zuckerberg said on Wednesday that, on average, ads now account for 5 percent or one in 20 “stories” in the newsfeed. That ratio could now provide a baseline for calculating success, prompting other Web companies to raise the frequency of ads in their streams.

“It wouldn’t surprise me if other companies would look at that and follow suit,” said Ansible’s Steele.

Hussein Fazal, the CEO of AdParlor, which manages advertising campaigns on Facebook, guesses that the social network must have gradually opened the spigot, gauging user reaction and adjusting the stream all the while.

They seemed to have hit on the right formula, but it’s one that differs across platforms, he said.

“The reason Facebook can do it is, the rest of the content that’s there is so engaging that you don’t mind one out of every 20 ads,” he said. “If you have a newsfeed that’s not so engaging, and you keep seeing ads, then it doesn’t work.”

Plus, the more ads in the stream, the less users will click on them, which can dampen ad prices, he added.

Facebook’s seeming success on mobile devices contrasts with Google’s more gradual improvement in that area. The No. 1 Internet search engine has gradually managed to narrow declines in its overall ad rates from the mobile effect, but last quarter they reversed and went down again, disappointing investors.

Google has avoided news stream ads entirely in its Google+ social network. Instead, its mix of mobile search ads, video ads and innovative formats such as “click-to-call” have delivered what RBC Capital Markets analyst Mark Mahaney estimates is a $10 billion annualized run rate for its mobile business, about four times as much as Facebook.

But mobile has driven down the average cost of Google ads, and some industry watchers consider the transition a long-term threat to the search giant. But other analysts say recent changes to the way it sells ads to marketers, blurring the distinction between the mobile and PC, could help bolster rates.

Stopping Google Latitude Service on August 9th

Stopping Google Latitude Service on August 9th

The world’s largest search engine company, Google will soon be officially shut down one of his services. The services that will be closed is Google Latitude which is a location sharing application.

Closure is made after a company based in Mountain View did a massive change on Google Maps. In addition, this application also has a very low popularity. Google Latitude consumption levels far below other applications such as Foursquare or Facebook. Not only that, Latitude also less popular than the location-sharing service owned by Google.

Google Latitude itself is a location sharing application that is integrated with Google Maps. This feature allows for automatic location tracking, check in at a place it can also be set automatically or manually.

In the latest update Google Maps on Android, this feature is not found anymore. Selian it, Google also removed the existence of Google Latitude app available on iOS and has officially retire the Latitude API. So third-party applications that use these APIs will not work, unless using a sharing site owned by Google.

Facebook Hashtags Not Catching on With Consumers

Facebook Hashtags Not Catching on With Consumers

While using hashtags in Facebook posts might be a fun tactic for brands trying to engage consumers, it doesn’t appear to be paying off, a new study finds.
Research from social media analytics firm Simply Measured revealed that while 20 percent of Facebook posts among top brands now include hashtags (which give users a way to group messages of similar content), there is no evidence that hashtags are influencing engagement.

The study shows that posts with hashtags —a new feature added with in the last several months — perform as well as those without, suggesting that people are not yet discovering brand posts by their tags.

Overall, the study shows nearly all of the companies in the Interbrand 100 — which ranks businesses based on financial status — now have a Facebook fan page, with 60 percent posting something at least once a day.

[No, Really, Facebook Makes Employees More Productive]

The research revealed that visual content is by far the primary driver for engagement on Facebook. Photos posted by top brands average more than 9,400 engagements, which includes likes, comments and shares, per post, while video posts average more than 2,500.

When it comes to text posts, brands must walk a fine line. Analysis of more than 500 status updates from the top brands shows that the longer a status update is, the less engagement it typically receives. However, if a status update is too short — less than 50 characters — it may not be long enough to capture viewers’ attention or provide the necessary context to drive the number of likes, shares and comments a brand would like.

“For most brands, Facebook is no longer just a network; it has become the hub of their social marketing efforts and one of the most effective ways to engage with fans,” said Adam Schoenfeld, CEO of Simply Measured. “This latest research once again proves that knowing your audience, understanding your content assets and measuring your efforts are extremely important to develop the social strategies that will work best for you.”

Businesses that limit Facebook fans from writing on their page might want to reconsider their strategy. The research shows that nearly 30 percent of top brands do not allow users to post on their wall. For those brands, user engagement on their page is limited to likes, comments and shares, resulting in 15 percent less engagement than brands that do allow user posts.

When it comes to drawing the most Facebook fans, no one does it better than Facebook itself. The social media giant claims the top spot with 93 million fans, followed by Coca-Cola and MTV.

Microsoft Denies Spying Issues Skype

Microsoft Denies Spying Issues Skype

CALIFORNIA – Microsoft has denied allegations that the government says it gave the United States (U.S.) direct access to a number of Microsoft products, including SkyDrive, Outlook.com, Skype, for the U.S. government (U.S.).

Reported by Read Write, Tuesday (16/07/2013), the software giant’s rebuttal to respond to a report in The Guardian, which has channeled suspect Skype user data into the monitoring program PRISM National Security Agency (NSA) since 2011.

Microsoft confirmed the company has clear principles in responding to government demands for user information related to law enforcement and national security issues. Perusahana consumers insist only provide data in response to legal process and only permitaan adhere to certain accounts or identification.

“We appreciate our commitment to the user and in accordance with applicable law very seriously, so we provide only to respond to consumer data due process. To be clear, Microsoft does not give the government direct access to SkyDrive, Outlook.com, Skype, or Microsoft products the other, “explains Microsoft.

In the end, Microsoft said, when companies update product liability law, may in some circumstances have to retain the ability to provide information in response to requests by law enforcement or national security.

“That’s why, we argue that additional transparency will help everyone understand and debate the important issues,” said Microsoft.

Maxthon Partners with AMD to Offer Web Browser Optimized for Next Generation APU Chips

Maxthon Partners with AMD to Offer Web Browser Optimized for Next Generation APU Chips

Maxthon, a cloud-based browser, today released a new version of its Windows browser that uses a revolutionary new microprocessor from Advanced Micro Devices (AMD), significantly reducing power consumption while offering superior video performance. AMD’s new Accelerated Processing Unit (APU) leverages new technology to make transactions between the graphics processing unit (GPU) and the central processing unit (CPU) faster and more energy-efficient than ever before.

“New chip architecture like AMD’s APU product is a clear signpost to where we believe the Web technology is heading: more happening in the chip and the browser serving as more of an open standards operating system,” said Jeff Chen, founder and CEO of Maxthon. “We’re proud to collaborate with AMD on such an exciting step forward.”

The GPU handles the processing of rich media including graphics and video, while the CPU manages the heavy lifting of analytical and logic-based functions. Until now, communicating across these two units has depended on a serial data connection that processes millions of functions per second, often resulting in a sluggish and power-consuming Web experience.

The partnership allows Maxthon to optimize the Windows browser for lightning-quick interaction between the APU to speed up video and graphics rendering, particularly using HTML5 standards for which Maxthon is the global leader in support. Among other things, the Maxthon Cloud browser is using OpenCL for lightning quick HTML5 video post processing to offer richer, faster video.

“In the near future what we now know as TV will be mediated through a Web browser optimized for innovative technology like AMD’s APU processors,” said Karl Mattson, vice president of Maxthon International. “Among other things, that means the electronic ‘hearth’ of the TV in the family room will be freed to be available to any device connected to the Web running a browser like Maxthon.”

Q&A: Microsoft Talks Changes to SkyDrive in Windows 8.1

Q&A: Microsoft Talks Changes to SkyDrive in Windows 8.1

When was the last time you had to delete a bunch of photos or apps on your mobile device to clear out space? With the massive amount of data generated every day, it’s easy to exhaust all the available storage on your phone or tablet.

And this problem is only getting worse. Industry trends suggest that device storage capacities are growing at 25 percent per year, but the amount of data being produced is increasing even faster — by around 50 percent a year, according to Microsoft. The software giant is looking to address this problem with SkyDrive, which will be updated in Windows 8.1 with the goal of giving you access to your files at all times, without taking up all your available storage or Internet bandwidth.

The updated service utilizes what Microsoft refers to as “placeholder files,” which look and feel like normal folders and files with one major change — you don’t download the full file until you access it. The placeholder file contains just a thumbnail image and some basic properties, making it significantly smaller than its actual size. This means that 100GB of files in SkyDrive will use up less than 5GB of storage on the hard drive of your Windows 8.1 device, Mona Akmal.

“I have a Pictures folder in SkyDrive that’s 5.6GB in size but it’s only taking up 185MB on the local disk,” Akmal wrote.

Another major change to SkyDrive in Windows 8.1 deals with offline access to files. With the SkyDrive app, you’ll now be able to mark any folders or files you want remain available when you lose Internet connectivity.

Any edits you make to a file while offline will automatically be synced back up to SkyDrive when you regain a connection. For added convenience, all the files you open or edit on your device will automatically be marked for offline access.

As a reminder, new SkyDrive users get 7GB of storage for free. After that, an additional 20GB costs $10 per year, while 50GB will set you back $25 a year, and 100GB costs $50 a year.

We sat down with Angus Logan, group product marketing manager for SkyDrive (pictured below), last week to get the scoop on the most important changes to the online storage service in Windows 8.1.
