  • Harness disruption or become obsolete: Forrester

    Five years ago, Nokia dominated the smartphone market. How quickly things change. But before you sit back and think, ‘that won’t happen to me’, take a look at the competitive environment in which your company operates. Daunting, isn’t it?

  • Curtains for MySpace?

    Things just keep getting worse for MySpace. The former social networking hub recently announced it would cut nearly half of its global workforce as part of a restructuring effort.   As many as five hundred MySpace employees worldwide will soon be looking for work as the site continues to redefine itself from a social network to an entertainment content site with social networking features.

  • Is there a replacement for Facebook?

    Facebook claims to have more than 400 million active users. In fact, according to Web analytics firm Alexa, only Google is a more popular site. So, with all that going for it, why are so many users unhappy, with one poll showing that more than half of Facebook users are thinking about leaving?

    Every time the economy turns downward, IT shops take a hit.

  • IBM CIO adjusts to his 'first pure-technology job'

    IBM CIO Mark Hennessy took on his current role in July, after 25 years of holding sales, marketing, and general management positions at Big Blue. In his "first pure-technology job," Hennessy is responsible for the technology needs of 372,000 employees worldwide, along with eight million square feet of data centers and thousands of servers and applications.

  • What If Yoda Ran IBM?

    The big vendors beat down the doors of large companies to get business, but a small-company CIO gets the brush-off. He wonders how to harness the powers of the Force, and get some big-company expertise to help the little guy.

  • How SOA could change the way you buy electricity

    What if IT could be used to eliminate the US West Coast's notorious rolling blackouts or huge regional power outages like those experienced by the Northeast and Midwest in 2003?

  • Can IBM save OpenOffice.org from itself?

    OpenOffice.org's biggest foe may be Microsoft Office, but critics say the open-source organization has, from its inception, also been one of its application suite's own worst enemies -- a victim of a development culture that differs radically from the open-source norm. Observers now wonder if IBM's entry into OpenOffice.org can make the necessary changes.

  • Unified communications: Here at last?

    While Todd Sharp is driving down the highway between Charlotte and Atlanta, a new sales order triggers a lookup for the customer phone number and salesperson (that would be Todd) assigned to it. The system then polls Siemens OpenScape UC (unified communications) software and checks Todd's presence status, discovering that he's working remotely and available only on his cell. OpenScape kicks off a VoIP call to Todd's cell phone and, using a text-to-speech engine, reads the sales order over the phone. It then prompts Todd to press 1 to autodial the customer. Minutes after the order arrived, Todd is thanking the customer from his car.

  • If these walls could talk

    Technopundits have predicted the arrival of "smart spaces" for years. Your car sends a message to a robot in your kitchen, so it can have your martini ready when you arrive home in the evening. A software agent on your LAN knows not to interrupt you with a phone call -- unless it's from your boss -- because you're working on a presentation for a meeting later that day.

  • Modernizing mainframe code

    By some estimates, the total value of the applications residing on mainframes today exceeds US$1 trillion. Most of that code was written over the past 40 years in Cobol, with some assembler, PL/1 and 4GL thrown into the mix. Unfortunately, those programs don't play well with today's distributed systems, and the amount of legacy code at companies such as Sabre Holdings in Texas, makes a rewrite a huge undertaking. "We're bound by our software and its lack of portability," Sabre Vice President Alan Walker says of the 40,000 programs still running on IBM Transaction Processing Facility (TPF), Agilent Modular Power System and other mainframe systems.

  • IBM's Business Insights Workbench smarter search

    Eight years ago, there were plenty of tools to search and analyze structured data, and even a few to go after unstructured information such as free-form text. But the two kinds of tools were not integrated, according to Jeffrey Kreulen, senior manager of service-oriented technologies at IBM's Almaden Research Center in San Jose. And the most sophisticated analytic tools used esoteric mathematical techniques that pretty much kept them out of the hands of nontechnical users.

  • Morphing the mainframe

    As distributed systems take on more mainframe-like qualities, the future of big iron hinges on its ability to adapt to the distributed computing revolution without being consumed by it.
