I've been working in the computer industry since 1977. For the first 6 years of my career, I worked as a field engineer which is basically a computer mechanic. In those days I serviced Honeywell and GE mainframe computers followed by a short stint working on DEC PDP-11 minicomputers. I only lasted 8 months maintaining DEC PDP-11 computers because they were so simple compared with mainframes that they weren't very challenging. Most of the service calls involved fixing the peripheral equipment such as line printers, disk drives, magnetic tape drives, card readers/punches, paper tape reader/punches, and a variety of terminals. The calls I enjoyed most were those which involved a computer which crashed or which failed to boot since those offered hours of debugging fun.
After having a DEC PDP-11 fall on me (it's a long story) in late 1982, I decided to make the switch from computer hardware to software since it seemed safer. It wasn't a huge change since I had been filling my idle hours working night shifts figuring out how to write machine language programs via the maintenance panel switches (see image below). After the long hours of figuring out the data patterns to write to memory via CPU maintenance panel switches, it was easy to use switch to using an assembler for generating the executable code for me.

Since then I've mostly worked on systems software in both assembly language and C. I've occasionally worked on networking protocols. There have also been a couple strange forays into other areas of the industry like 9.5 years working on the software which runs on cable TV set-top boxes. The technology was interesting and I loved the company but I really missed systems programming.
In 1990 I discovered that I have a strong preference for Unix and Unix like operating systems when I took a job which gave me a Sun workstation to use. Unix made me so much more productive that I couldn't bear the thought of not having access to it. Since then I've tried to only take jobs which satisfied that itch. Whenever I've been stuck using Windows somewhere, I've usually installed Cygwin to give myself access to a Unix style development environment. The exception is my current job which has given me a Windows laptop too locked down to be able to install Cygwin. Fortunately, I have multiple Linux servers at my disposal as well.
Since 1994 I've been working mostly at startup companies. Several have been bought by larger companies which inevitably leads to unpleasant changes in company culture which I haven't enjoyed. For example, in 1996 I took a job at a startup which developed ISDN modems shortly after it had been bought by U.S. Robotics. USR managed to preserve the small company feel of our office but that disappeared when USR was bought by 3Com a couple years after I joined. It was a shame since I really enjoyed the great group of people I worked with there but 3Com's changes made it clear that they would eventually shut down that remote office which they did about a year after I left.
One of my favorite projects at USR was an ADSL modem which connected to a Windows PC via USB. We were developing that device in late 1997. Windows 95 only supported USB via a USB support package and it really didn't work that well. Windows 98 and later Windows 2000 fixed many of Windows' problems with USB but we had to do full drivers before the USB interface was documented in the Windows DDK. This was during the early days of USB so the USB communications device class didn't exist yet. I spent many hours with a USB analyzer verifying that we had the protocol correct. USB has remained one of my favorite technologies to work on ever since.
After leaving USR, I took a job at an optical networking startup called Ocular Networks. That was another great group of people to work with until Tellabs bought the company. I enjoyed the team I worked with so much that we started meeting for regular happy hours at the Old Dominion Brew Pub once a week after work. After I left Tellabs, I didn't want to lose contact with my friends, so I started a mailing list to continue our regular happy hours.
Old Dominion Brew Pub was a wonderful place to meet. They had great good, interesting beer, and a pleasant atmosphere. Unfortunately, Old Dominion sold their brewery and brew pub around 2008 and the new owner moved their brewing operations up to Delaware. That left our happy hour group a number of places to meet for happy hours, none of which seemed to last more than a few months. We wandered from place to place until the Fairfax Dogfish Head Alehouse opened in 2009. We continued meeting there until the pandemic made it hard to do in-person meetings. After that, we changed our happy hours to virtual ones, meeting via video chats. Unfortunately, between the slowdown caused by the pandemic and a landlord who kept raising the rent, DFHA ended up having to close their Fairfax location in 2023.
