All creators and developers on the web require at least one of the tools offered on dnsstuff.com.

If a site appears to have gone down, your email address isn’t working, dnsstuff.com is the ultimate way to figure-out at what level the problem exists. It is also extremely useful for researching information on sites.

When you’re sending an email with an attachment, do you zip the attachment?
Have you ever sent a document to someone only to find out that the document the recieved, won’t open, or doesn’t look right?

Email itself is very prone to having it’s attachments corrupted. By zipping a document, not only do you shrink the size of the document to be sent, but you are also encasing it in a way that prevents tampering with the data itself.

By shrinking the size of the document you are lessing the chance of corruption by sheer ratio.

Kismet is a tool for wireless sniffing (just viewing what’s already passing through the air). And KisMAC is the OSX version. Best part about KisMAC is the Apple Airport Extreme card drivers for both Active and Passive support. Active, meaning you can see but can’t collect, and passive meaning you can see and collect.
So if your on OSX and you want to see the wireless in your area and collectively watch what’s be sent around, getting KisMAC is a good starting place.
