Extending the life of your data center

This year marks the 10th anniversary of the 1,200-square-foot data center at the Franklin W. Olin College of Engineering -- that means the facility has been operating three years longer than CIO and vice president of operations Joanne Kossuth had originally planned. Now, even though the school needs a facility with more capacity and better connectivity, Kossuth has been forced to back-burner the issue because of the iffy economic times.

Four questions for Dan Bricklin, VisiCalc inventor

Dan Bricklin first came up with the idea of an electronic spreadsheet while he was at Harvard Business School in 1978. He later joined forces with Bob Frankston and Dan Fylstra to publish the now-legendary VisiCalc in 1979. Bricklin, currently president of software developer Software Garden Inc., recently spoke with Computerworld about the intent of VisiCalc and how the spreadsheet has evolved.

Moving to the cloud: Big savings, but plan ahead

Some might say that San Diego-based <a href="http://www.amylin.com/">Amylin Pharmaceuticals</a> was pushed into the cloud. The 23-year-old company's data center had been running at 100% capacity and IT executives feared inevitable performance problems, but the company was reluctant to build another site due to the poor economic climate.

Planning for virtualization? Beware of server overload

Want a four-day workweek? IT is key

As oil prices continue to fluctuate, the economy flounders and the pressure is on to slow global warming, both public- and private-sector organizations are turning to alternative work schedules such as telecommuting, flex time and four-day workweeks to ease the pain to their bottom lines, their employees' wallets and the environment.

Six hours to hack the FBI (and other pen-testing adventures)

It takes a lot to shock Chris Goggans; he's been a pen (penetration) tester since 1991, getting paid to break into a wide variety of networks. But he says nothing was as egregious as security lapses in both infrastructure design and patch management at a civilian government agency -- holes that let him hack his way through to a major FBI crime database within a mere six hours.

Utility storage: Ready for a long haul?

First will come virtualization, then utility storage. That's long been the vision of how enterprise storage will evolve as IT grows increasingly dynamic and on-demand becomes business as usual.

Can your network handle HD video?

Consider this: In the week following September 11, 2001, your users were glued to their television sets tracking breaking news. If an event of similar proportions happened today, they would expect the enterprise network to be able to handle not only real-time video feeds but also high-definition videoconferences and surveillance, as well as instant access to social-networking tools.

Beware videoconferencing pitfalls

With the rise in adoption and availability of enterprise videoconferencing systems comes a warning from IT pioneers: Thinking this technology is simply plug-and-play will lead to disaster.
