The Shortest Path Problem in a Dynamic Network.

A method is needed by which efficient new network routes can rapidly be
calculated to route traffic away from problem paths and nodes. A
possible method is proposed.  I propose to call it the Wentrok heuristic.

The Rock And The Hard Place Of Homer

The well-known expression: 'between a rock and a hard place' almost certainly has its earliest origins in Homer's Odyssey. In that saga, Ulysses has to take his ship between Scylla and Charybdis, two rock-monsters which are a bow-shot apart. It is impossible to avoid both monsters - a course must be steered which leads to the least loss of life.

Using Encryption to Block Spam

Tackling the problem of spam is a problem in communication. If spam is noise as against wanted communications, then the spam problem is a signal to noise filtering problem. Unwanted emails, especially broadcast spam emails, consume about 80% of currently available bandwidth.  We need to filter out the 80% noise so as to increase the efficiency of the web in distributing the 20% of traffic that is the wanted signal.
