We are now seeing a seismic shift and increase in the significance of social network data for marketing and brand analysis. The next wave of social network exploitation promises to allow companies to narrowly target consumers and leads to predict market trends, and to more actively influence consumer behavior.

In this month's column, Guy Harrison writes about Docker, an open source project based on Linux containers that is showing rapid adoption. "Unlike virtual machines, Docker containers do not have to include a copy of the guest OS - each Docker container essentially shares the same copy of the underlying OS," explains Harrison. "This allows Docker containers to be much smaller, which, in turn, allows them to be more easily deployed, provides for greater density (more containers per host) and permits faster initialization."

Competitive differentiation in the mobile space depends only peripherally on the hardware - all modern smartphones have similar processing, display and networking capabilities. And, while some are notably superior in terms of a niche capability - cameras, for instance - it's the software, rather than the hardware, that separates the platforms.

The "Internet of Things" (IoT) is shifting from aspirational buzzword to a concrete and lucrative market. New-generation computing devices require new types of operating systems and networks. While many have been initially based on some variation of the Linux OS and connect using existing Wi-Fi and Bluetooth wireless protocols, new operating systems and networking protocols are emerging.

Ironically, although the thin client advocates were right about many things - the success of browser-based applications, in particular - they were dead wrong about the diminishing role of the OS. More than ever, the OS is the source of competitive differentiation between various platforms, and a clear focus of innovation for the foreseeable future.

New devices promise to open up ways for us to improve our mental functioning and perhaps to further revolutionize social networking and big data. A world in which Facebook "likes" are generated automatically might not be far off, and mining the big data generated from our own brains has some amazing - though sometimes creepy - implications.

Two new approaches to application quality have emerged: "risk-based testing" - pioneered in particular by Rex Black - and "exploratory testing" - as evangelized by James Bach and others. Neither claim to eradicate issues of application quality, which most likely will continue as long as software coding involves human beings. However, along with automation of the more routine tests, these techniques form the basis for higher quality application software.

We've seen a lot of progress in the nearly 50 years between 1965 and 2013: the modern smartphone and the World Wide Web, in particular,have been transformative. However, it's probably true that our current world would not astonish a time traveler from 1965 as much as 1965 would have surprised a visitor from 1915. Where are the jetpacks, flying cars, colonies on Mars? However, it does look like we are finallygoing to see one of the long-awaited benefits of the future: the self-driving car.

Like many of my generation, my early visions of the future were influenced by films like "2001: A Space Odyssey" and the original "Star Trek" TV series. In each of these, humans interact with computers using conversational English, posing complex questions and getting intelligent relevant responses. So, you can imagine how primed someone like me is to hear that Google has been explicitly trying to create that Star Trek computer. At the Google IO conference in San Francisco in May, Amit Singhal, Google senior vice president, spoke of his early childhood experiences watching "Star Trek," and his dreams of one day building that computer.

Computer games have been front-runners in many important developments in the IT industry, including digital distribution, cloud storage, user driven design, and crowd sourcing. So it's not surprising that game developers are in a leading position when it comes to big data analytics and machine learning. Online games have the ability to monitor all aspects of player behavior, so, just as Google is able to refine your search results by analyzing your previous searches and comparing them to the billions of searches done every day, online game companies are able to modify game behavior to ensure a more optimal game experience by observing what works - and what doesn't - in the gamer's world.

Google's dominance of internet search has been uncontested for more than 12 years now. Before Google, search engines such as AltaVista indexed web pages and allowed for keyword search with an interface and functionality superficially similar to that provided by Google. However, these first-generation search engines provided relatively poor ordering of results. Because an internet search would return pages ranked by the number of times a term appeared on the website, unpopular or irrelevant sites would be just as likely to achieve top rank as popular sites.

Coverage of Windows 8 has understandably focused on the revolutionary Metro interface. Many believe that this new interface, while fine for tablets and phones, is a step backwards for desktop productivity. By forcing users to switch between two modes of operation - desktop and Metro, Windows 8 diminishes productivity and imposes steep learning curve on new users. The Metro interface itself supports only very limited multi-tasking, so, serious work often must be done in the traditional Windows desktop. Microsoft implicitly acknowledges these limitations by providing the latest version of Microsoft Office, not in Metro format, but as traditional "desktop" applications.

Five years ago, Radio Frequency ID (RFID) seemed posed to revolutionize commerce. Way back in 2003, Wal-Mart announced that it would be requiring that RFID tags - so called "electronic barcodes" - be attached to virtually all merchandise. Many- myself included - became convinced that the Wal-Mart directive would be the tipping point leading to universal adoption of RFID tabs in consumer goods and elsewhere.

The first computer program I ever wrote (in 1979, if you must know) was in the statistical package SPSS (Statistical Package for the Social Sciences), and the second computer platform I used was SAS (Statistical Analysis System). Both of these systems are still around today—SPSS was acquired by IBM as part of its BI portfolio, and SAS is now the world's largest privately held software company. The longevity of these platforms—they have essentially outlived almost all contemporary software packages—speaks to the perennial importance of data analysis to computing.

Seriously chronic geeks like me usually were raised on a strong diet of science fiction that shaped our expectations of the future. Reading Heinlein and Asimov as a boy led me to expect flying cars and robot servants. Reading William Gibson and other "cyberpunk" authors as a young man led me to expect heads-up virtual reality glasses and neural interfaces. Flying cars and robot companions don't seem to be coming anytime soon, but we are definitely approaching a world in which virtual - or at least augmented - reality headsets and brain control interfaces become mainstream.

Websites such as MySpace, Facebook, and LinkedIn have brought social networking and the concept of online community to a huge cross-section of our society. Penetration and usage of these platforms may vary depending on demographic (age and geography, in particular), but no one can debate the impact of Facebook and Twitter on both everyday life and on society in general.

Knowing how your customers feel about your products is arguably as important as actual sales data but often much harder to determine. Traditionally, companies have used surveys, focus groups, customer visits, and similar active sampling techniques to perform this sort of market research. Opposition or lack of faith in market research takes a number of forms. Henry Ford once said, "If I had asked people what they wanted, they would have said faster horses," while Steve Jobs said, "People don't know what they want until you show it to them." The real problem with market research is more pragmatic: It's difficult and expensive to find out what people think.

My 20-year-old daughter recently remarked that Facebook isn't as cool as it used to be. Sure, everyone has to be on Facebook, but that very ubiquity removes its mystique. The recently released Google+ is clearly targeted at Facebook and adds some features - particularly "Circles" - that are not available on Facebook. Facebook dominance may be indisputable today, but it is not guaranteed for all time. If I were Mark Zuckerberg, I would fear losing my cool status more than anything else.

The term "machine learning" evokes visions of massive super computers that eventually turn on and enslave humanity - think SkyNet from Terminator or HAL from 2001: A Space Odyssey. But the truth is that machine learning algorithms are common in web applications that we use every day and have a growing relevance to enterprise applications.

One of the funniest moments in the classic Star Trek motion pictures is the scene when the engineer "Scotty" - who has traveled back in time to the 1980s with his comrades - attempts to use a computer. "Computer!" he exclaims, attempting to initiate a dialogue with the PC. Embarrassed, a contemporary engineer hands him a mouse. "Aha," says Scotty who then holds the mouse to his mouth only to again exclaim, "Computer!" The idea that computers in the future would be able to understand human speech was common a few decades ago. Speech generation and recognition is so fundamental to the human experience that we tend to underestimate the incredible complexity of human information processing that makes it possible.

When computers first started to infringe on everyday life, science fiction authors and society in general had high expectations for "intelligent" systems. Isaac Asimov's "I, Robot" series from the 1940s portrayed robots with completely human intelligence and personality, and, in the 1968 movie "2001: A Space Odyssey," the onboard computer HAL (Heuristically programmed ALgorithmic computer) had a sufficiently human personality to suffer a paranoid break and attempt to murder the crew!

The NoSQL acronym suggests it's the SQL language that is the key difference between traditional relational and newer non-relational data stores. However, an equally significant divergence is in the NoSQL consistency and transaction models. Indeed, some have suggested that NoSQL databases would be better described as "NoACID" databases - since they avoid the "ACID" transactions of the relational world.

Oracle CEO Larry Ellison has been notoriously critical of cloud computing - or at least of the way in which the term "cloud" has been applied. He often has expressed his frustration when "cloud" is applied to long established patterns such as software as a service (SaaS), especially when this is done by Salesforce.com. While there's widespread agreement that "cloud" has become a faddish, over-hyped and often abused term, some have speculated that Ellison's obvious frustration has been fueled by Oracle's inability to fully engage in the cloud computing excitement prior to the conclusion of the Sun acquisition.

The promises of public cloud computing - pay as you go, infinite scale and outsourced administration - are compelling. However, for most enterprises, security, geography and risk mitigation concerns make private cloud platforms more desirable. Enterprise customers like the idea of on-demand provisioning, but are often unwilling to take the performance, security and risk drawbacks of moving applications to remote hardware that is not under their direct control.

In biology, we are taught that survival favors diversity. Organisms that reproduce without variation die out during periods of rapid change, while organisms that show variation in feature tend to survive and adapt. Likewise, ecosystems consisting of relatively few homogenous species thrive only when conditions stay static. Does IT diversity create a competitive advantage in the business application ecosystem? Predictably, large vendors with vertically integrated stacks argue that mixing software components is a Bad Thing. These vendors claim that reducing the diversity in the application stack leads to better efficiency and maintainability.

Although VMware continues to hold the majority share of the commercial virtualization market, other virtualization technologies are increasingly significant, though not necessarily as high profile. Operating system virtualization-sometimes called partial virtualization-allows an operating system such as Solaris to run multiple partitions, each of which appears to contain a distinct running instance of the same operating system. However, these technologies cannot be used to host different operating system versions, making them less appealing to enterprises seeking to consolidate workloads using virtualization.

Until recently, IT professionals have been conditioned to regard response time, or throughput, as the ultimate measure of application performance. It's as though we were building automobiles and only concerned with faster cars and bigger trucks. Yet, just as the automotive industry has come under increasing pressure to develop more fuel-efficient vehicles, so has the IT industry been challenged to reduce the power drain associated with today's data centers.

Spreadsheets, which have long been a disruptive force to enterprise IT, to some extent are the "killer" applications that helped drive the adoption of personal computers (PCs) in the enterprise. Spreadsheet products such as Lotus 1,2,3 - and early versions of Excel on the Mac - saw rapid adoption by business users. Inevitably, these users pushed the boundaries of the spreadsheet model, using spreadsheets as databases, and even to develop simple business applications. In the late 1980s, it was typical to see corporate IT rolling out massively expensive mainframe-based solutions, while departmental users got their real work done on spreadsheets running on cheap PCs.

In 1995, Netscape founder Marc Andreessen famously claimed that applications of the future would run within a web browser, relegating the role of the operating system - Windows, in particular - to "a poorly debugged set of device drivers." Fifteen years later, we can see that although rich applications such as Microsoft Office are still dominant, the web browser has become a platform that can deliver almost any conceivable type of business or consumer application.

Google's first "secret sauce" for web search was the innovative PageRank link analysis algorithm which successfully identifies the most relevant pages matching a search term. Google's superior search results were a huge factor in their early success. However, Google could never have achieved their current market dominance without an ability to reliably and quickly return those results. From the beginning, Google needed to handle volumes of data that exceeded the capabilities of existing commercial technologies. Instead, Google leveraged clusters of inexpensive commodity hardware, and created their own software frameworks to sift and index the data. Over time, these techniques evolved into the MapReduce algorithm. MapReduce allows data stored on a distributed file system - such as the Google File System (GFS) - to be processed in parallel by hundreds of thousands of inexpensive computers. Using MapReduce, Google is able to process more than a petabyte (one million GB) of new web data every hour.

When a company like Microsoft talks about the future of computing, you can expect a fair bit of self-serving market positioning - public software companies need to be careful to sell a vision of the future that doesn't jeopardize today's revenue streams. But, when a company like Microsoft releases a new version of its fundamental development framework - .NET, in this case - you can see more clearly the company's technical vision for the future of computing.

There's an old but clever internet parody describing the "Built-in Orderly Organized Knowledge device (BOOK)."

Though satirical, the article makes excellent points: the printed book is indeed an information technology device, arguably the oldest in widespread use today

The idea of "virtual" reality—immersive computer simulations almost indistinguishable from reality—has been a mainstay of modern "cyberpunk" science fiction since the early 1980s, popularized in movies such as The Thirteenth Floor and The Matrix. Typically, a virtual reality environment produces computer simulated sensory inputs which include at least sight and sound, and, perhaps, touch, taste and smell. These inputs are presented to the user through goggles, earphones and gloves or—in the true cyberpunk sci-fi—via direct brain interfaces.

Predictive Analytics - sometimes referred to as Predictive Data Mining - is a branch of Business Intelligence that attempts to use historical data to make predictions about future events. At its simplest, predictive analytics utilizes statistical techniques, such as correlation and regression, which many of us have encountered in college or even high school. Correlation analysis determines if there is a statistically significant relationship between two variables. For instance, height and age are highly correlated, while IQ and height are very weakly correlated. Regression attempts to find an equation between the two or more variables, so that you can predict one from the other.

Both open source software ( OSS) and cloud computing continue to experience strong interest and growth despite the economic downturn. Clearly, both provide the promise of reduced operating and software licensing costs. For instance, corporations looking to reduce the cost incurred by Microsoft Office licensing are looking more closely at the open source OpenOffice alternative, or at Google's online application suite, Google Apps. There's understandable resistance to moving from the rich experience offered by Microsoft to these lower-cost alternatives, but resistance has a way of disappearing in the face of financial imperatives.
