Debugging the freezer
For some time my freezer at home was behaving strangely. Going to alarm mode because of temperature rising, but then restarting normal freezing operations when setting super-freeze mode on the control panel. It was then working correctly for one or two days and then going to alarm mode again.
Weird... obviously not a mechanical problem because super-freeze quickly brought the temperature to -30°C. A malfunctioning relay? Let's open the beast.
No relay there. All electronics, and... a tiny fly, less that 2 millimeters long, that got burnt between a transistor and a LED pins on the control panel and was perturbating the temparature regulation.
I removed the dead body of the poor fly, put back together the freezer pieces, and there we go. The freezer has been freezing normally again for about one week now!
A nice reminder for us computer geeks of where software bugs come from!

Pheeew...for an instant I thought you were going to tell us that your freezer runs on Windows ;-)

So i would like to know if the "viral" invitations on joost does still exist, and if i can join the list ?
And if you could explain to me in simple few words (i comme from paris :o)the "joost" concept , that would be great.
Looking forward to your reply i remain with best regards.

Well here I thaught that computers only get bugs in them. LOL. Maybe you should see if there is some type of Anti-Bugware for your freezer to prevent it from happening again. Anyways I got a magazine today called Windows Vista the Official Magazine and there was an artical about joost.com. So I went to check it out as I am a real computer geek. But I could not get it. Ga-zooks. LOL. How do I go about getting this? I would like to give it a try. I like to check out new things. Especially when it deals with computers.

This is all very exciting, and what I have been waiting for a long time. My new machine with the big screen is just hungry for it too. But how do I get invited?
