Cisco Express Forwarding. An awesome cool feature that was added to Cisco routers about 8 or 9 years ago. Reduces the CPU utilization of the router when making forwarding decisions (Layer 3 IP routing) through the use of cached destination information and adjacency tables to quickly determine the Layer 2 next hop without having to discover it for each packet. Best improvements of speed come when dCEF (Distributed CEF) is running on individual line cards on 7500 series routers, so each card can make layer 3 switching decisions without having to hit the central CPU. It is like magic pixie-dust nitro fuel for routers, and like all twitchy high-performance systems, sometimes things go really wrong. CEF was buggy when released and was often been the source of really weird bugs and middle of the night "gotcha" issues.

Orbital was a UK based techno-music band, and one of my first exposures to electronica. I think I got their first album (self-titled, but otherwise known at the "green" album) in the mid-90s, with classics like "Belfast" and "Chime". I have found their music to be a little more polished than other early techno. I always wanted to see them play live, but since they broke up in 2004, that is unlikely now.

Open Shortest Path First, a network routing protocol that uses Dijkstra's algorithm to compute the best path between two points. It is pretty much the de-facto network routing protocol standard for interior gateway routing. Despite the fact that I have been using OSPF since 1995 or so, I still feel that I barely know anything about it. But I seem to know more than most people.

This icon is a screen capture from the title page to the PLATO/NovaNET classic game called "avatar", which was originally created in 1978. The game was a multi-user "dungeon and dragons" type monster killing and treasure quest sort of game. It was better than anything else available for years.
Imagine a game with 100+ concurrent users from all around the country interacting in real time in a virtual world environment (limited 3D wire frame dungeon) with text chatting, and a game design that featured hundreds of monsters and treasure types, and that required player cooperation and skill to kill the big monsters... now imagine that using 1978 level technology. The whole PLATO system was remarkable and was far ahead of its time. It was a richly interactive mainframe timesharing system (CDC Cyber mainframes originally) that used 512x512 pixel resolution monochrome gas plasma displays (and later color on PCs), had very low latency, featuring email, groupware, and real time chat.
I spent many thousands of hours (yes, thousands) playing this game during the late 80s and early 90s. I had dozens of friends who played the game with me, and we were the biggest group of players in the game (many maximum level characters with maximum possible equipment). It literally was my life for a while, and it seemed right as my default user picture. I don't regret that time, and I know now that I can never get involved in World of Warcraft or similar MMORPGs, or I would quickly become homeless.

This is a quote from Chef from the South Park episode "Cartman Gets an Anal Probe". It just seemed amusing. Despite the fact that I think South Park is amazingly funny, I almost never get a chance to see it. The icon was created using xach's LISP based SignBot (http://wigflip.com/signbot/) website. I use this icon rarely. It is supposed to be for posts that are funny.
Moon
A generic moon picture I found. When I feel stressed out or overwhelmed by petty events in life, I like to look up at the moon and the stars and think about how none of this earthbound stuff really matters, and that the universe will go on long after I am gone. I use this icon when I am feeling stressed or reflective upon life.
