Yesterday evening, I was supposed to fly to New Jersey for an all day meeting today. The weather was a little overcast, and there had been a few showers earlier, so I didn’t think there were going to be too many problems. When I fly to NJ, I always take the 7:45 out of Columbus,…
(… or how to shed 25 thousand NFSOPS per second off your filer in 3 easy steps) So, we did a large upgrade of the environment over the weekend. It mostly went ok, despite some dramatic schedule slips. We still fit inside the overall window; it just didn’t end up as short as we wanted…

In my efforts to generate an SA skills matrix, I’ve discovered that we haven’t managed to quantify what we do in categories in a clear and consistent manner.

Today’s “Ohio LinuxFest”:http://www.ohiolinux.org/ was quite an interesting event. Doug and I were the only two LOPSA members working the booth, although a few local-ish members stopped by to say “hi”. Because of that, the only time either of us got out from the booth was to stretch our legs, and when I served on the…
Stephen Potter and I are meeting lots of new potential members here . At least one new member has already signed up. Since they don’t have official networking, I’m logged in via GPRS. Many people haven’t heard of LOPSA, so raising awareness is part of our target. The event looks to be a big success….
