Securing Your Laptop

The plug-in Yoggie Gatekeeper Pico promises to supersede standard antivirus and antispam software, but it's not for everyone

2 min read

I’m a paranoid computer user. The first thing I do with a PC is install a full suite of ”anti-” software programs—antivirus, antispy, antispam, you name it. I even leave Microsoft Vista’s ”Annoy me constantly” mode turned on. So when I got a browser virus anyway, I lost my faith in my software security shields.

Just in time, along came the Yoggie Gatekeeper Pico. It’s a USB stick that bills itself as a replacement for all the security software we ordinarily run under Windows, designed with laptops in mind. All network traffic, wired or wireless, goes through the Pico before any Windows software sees it. And because the Pico is itself a complete computer, running Linux on an Intel XScale processor, it promises to bump up performance by supplanting the security software that now sucks cycles from your laptop’s central processing unit.

It’s hard to learn, but your code will produce fewer nasty surprises

A plate of spaghetti made from code
Shira Inbar

You’d expectthe longest and most costly phase in the lifecycle of a software product to be the initial development of the system, when all those great features are first imagined and then created. In fact, the hardest part comes later, during the maintenance phase. That’s when programmers pay the price for the shortcuts they took during development.

So why did they take shortcuts? Maybe they didn’t realize that they were cutting any corners. Only when their code was deployed and exercised by a lot of users did its hidden flaws come to light. And maybe the developers were rushed. Time-to-market pressures would almost guarantee that their software will contain more bugs than it would otherwise.
