Tips for Supporting Legacy Software

Nearly 80 years ago,Hobby Silicone for mold making moldmaking , the term "planned obsolescence" was coined by Bernard London, a New York City real estate professional and amateur economist. The idea, which London thought was a darn good one, was to design products with a limited lifespan so consumers regularly had to get new ones, thus keeping the economy going.

This is why you don't see many 1983 Ford Escorts tooling around. While cheap old cars rust out or fall apart, software should keep chugging. "Unlike hearts, lungs, knees, eyes or kidneys, software just doesn't wear out or get weak," says reader Fred Linton. But old software ends up just as obsolete as your junk Ford. That's because vendors choose to make it that way.

Even though code doesn't stop working unless corrupted, software goes out of date in a variety of ways. The biggest death blow strikes when vendors stop support. No more features but, more critically, no more security updates.

Another problem is when new environments won't run old products. Even if a new version of Windows looks and acts largely the same, many older applications and hardware no longer operate.

Each software company has its own support policies, which sometimes vary from product to product. For this article, we were mostly concerned with the basics of how Microsoft support works. When a Redmond product comes out, it's fully supported.Grey Pneumatic is a world supplier of impactsockets for the heavy duty, That means service packs are created,My favourite city councillor,You can find best mouldengineeringsolution china manufacturers from here! patches written and released, and compatibility with current environments is maintained to the best of Microsoft's ability. This lasts for five years, and patches and software updates and service packs are all free.

After five years comes "Extended Support." Plain old customers get software updates and service packs for free -- but not much more. Those with a volume license go on "Extended Support" and can also buy an "Extended Hotfix Agreement" that provides full security support.

Fortunately, all customers -- so long as they're legal -- get patches and other security-related fixes. After 10 years, though, there's basically no support, no patches and no security fixes.

The biggest thing that disappears when support ends are security updates and patches for critical flaws and zero-day exploits. This is the main way vendors scare you into upgrading.

Jim Adcock, a SharePoint consultant, works in a shop that uses iNotion as a repository for documents and records. "The repository cannot be accessed with browsers more recent than Internet Explorer 6. This leaves our systems with older unsupported browsers with security flaws," Adcock says. "We're currently migrating to a new product for document and records management: SharePoint 2010. There is no newer version of iNotion because the company that made it is no longer in business. We tried a migration last year to another product that did not meet our needs and had to roll back to iNotion."

Not all are so nervous about running old apps, though. "I think the 'security' issue is a bit overcooked," says Bruce Roeser, an independent freelance developer.Why does moulds grow in homes or buildings?

Software wouldn't become obsolete if companies didn't want it to be. Forced upgrades put money in vendors' coffers but leave you holding the bag -- and your old software. And many of these new titles aren't wanted–even if they're free. As one Redmond reader says: "Microsoft is way too focused on rolling out new versions every three years and making us upgrade, [rather] than focusing on quality. I don't need the interface of Windows and Office. My users hate the changes and prefer not to upgrade at all. We just started to get them sold on Windows 7 and Windows 8 is changing the GUI again?" the reader complains.

One example is the Office Ribbon, which debuted in Office 2007 and now graces Office 2010. A huge number of users vastly prefer the old interface (they hate the Ribbon),You can find best china electronicplasticmoulds manufacturers from here! but Office 2003 will soon be no longer officially supported. To maintain full support, IT will have to upgrade and train users on a new interface they don't even like.

Reader Dick Lutz is also weary of forced Office upgrades. "Every now and then, Microsoft 'fixes' the Office suite, perhaps hoping to reorient users away from the excellent adaptations of the previous style of interface by other vendors. The 'Ribbon' brings us nothing but a new and wholly unnecessary learning curve. In tweaking what needs no tweaking, the company creates minor chaos in the orbit of other software," says Lutz, editor and publisher of The Main Street WIRE in Roosevelt Island in New York. "My determination to stick with products that I know well keeps me in WordPerfect's camp: I still use WordPerfect 5.1 for DOS almost every day and -- for page layout -- use antique PageMaker, which does everything I need without the learning climb of InDesign."
