We ran across a very creative use of Pingdom monitoring the other day. Most people use Pingdom to monitor the status of websites and servers, but Eric Nagel uses our monitoring service to keep track of the temperature in his outdoor hot tub (complete with rubber ducky).

How does he do it? He uses a wireless temperature sensor (seen bottom right in the picture below) that he checks the status of via his own server. A small script generates an online status page that contains either “OK” or “Too cold.” This status page is monitored with Pingdom, so Eric will get an alert via SMS if his hot tub is too cold.

Nifty, isn’t it? To see exactly how he set things up, head over to Eric’s blog.

It’s official. You can monitor ANYTHING with Pingdom.

(If you’re using the Pingdom monitoring service in unusual ways, don’t hesitate to let us know. We love this kind of stuff! Who knows, we may even write a blog post about it…)

Unless you’ve been hiding under a rock lately, you’ll know that last week Apple announced the iPad, its new tablet device. Reactions have been a mixed bag, and a storm of discussion has swept through the blogosphere about various features the iPad should or shouldn’t have had.

One of the main complaints so far has been the iPad’s lack of multitasking. (To be precise, multitasking is a bit of a misnomer here; the iPhone OS has multitasking. What people really mean is only allowing one app at a time to run.)

The tech industry is littered with billionaires. We all enjoy a good income, but some clearly have earned more than others. Much, much more. The question is, how much money do the really big names in tech actually have?

To find out, we went through the Forbes 400, a list of the wealthiest Americans, and filtered out the people who work within the tech field, or more specifically: IT.

So here they are, the 20 richest Americans in tech today.
