Networking Fact of the Day

The default starting port in UNIX traceroute is 33434. This comes from 32768 (2^15, or the max value of a signed 16-bit integer) + 666 (the mark of Satan).

Dijkstra's algorithm. It picks the unvisited vertex with the lowest-distance, calculates the distance through it to each unvisited neighbor, and updates the neighbor's distance if smaller. Mark visited (set to red) when done with neighbors.

All the Best to Boston
