IBM's OS/2 operating system is heading rapidly for the end of its standard support lifetime at Deceber 31, 2006. IBM is urging customers to transition to the WebSphere platform. I take a stroll down memory lane through OS/2, Desqview, the BBS and FidoNet community, Windows NT 3.1, and SLIP/PPP dialup accounts.

TCP port 25 considered harmful?

Mailing lists are a great resource, even in this Latter-Day Dispensation of Search Engines and Web Forums. While web forums have their place, there's nothing like being able to carry on an extended conversation in the comfort of your own Inbox. I was inspired by a drive-by comment on a recent thread I participated in to take a step back and examine the practice of port-blocking TCP 25, which is the port used by the Simple Mail Transfer Protocol (SMTP).
