Have you ever wanted to see the health of your network in a graph? To see when your ISP goes offline? Have you wanted to see when the remote office in Possom Trot has had its router go down? PingGraph is your answer.

MultiHash builds MD5 hashes of single files, sets of files, directories, or entire drives. These hash values are published by some software vendors so you can verify that your downloads match their calculated hash values. This guarantees the integrity of the download and assures that nobody has modified the files.
So now you can not only verify the MD5 hash values of other software providers, you can create your own, or verify whether two directories are exact duplicates.

GPSMonitor is freeware, meant to be downloaded and run without any need to pull out that battle-worn credit card.
