March 10, 2003 was just another day when you’re working in tech. At least, that’s what I thought until things started to pile up.

The Morning Commute

I woke up early as usual, and my wife asked if I could pick her up from the airport on my way into work. The plane landed right at 7:15 AM, and I made it just in time with a few minutes to spare. But by “sparing,” I mean I had to sit through an hour of the guy who was driving us home swearing at every car that tried to pass him.

The Morning Debug

Arriving early is always a good idea when you’re dealing with servers, but today it was a little too early. When I got into the office, I found my team already in a huddle around our server room. The new Xen hypervisor we had just deployed on some of our production machines wasn’t quite living up to expectations.

I remember feeling a bit self-deprecating when I saw them. I mean, it was only day one and I couldn’t get the hypervisor to work as smoothly as I’d hoped. But I kept my cool and started investigating why some VMs were consistently failing to boot.

After a few fruitless attempts with the standard command line tools and a quick peek at the logs (which seemed mostly empty), I decided it was time for some good old strace. It turns out that one of our startup scripts had an issue with path resolution. A simple symlink problem, but it took me longer than it should have.

The Lunch Break

Lunchtime came and went like any other day. We headed over to the usual sandwich joint down the street, and I couldn’t help but think about how much easier things would be if I could just grab a quick slice of pizza instead. But then again, who knew what kind of security risks an Italian place might have compared to my office kitchen?

As we were eating, one of our developers mentioned that they had been testing the new Firefox and was blown away by its performance. It made me realize how quickly technologies evolve. I still remember the first time I saw Netscape back in ‘95; it felt like magic at the time.

The Afternoon Hack

After lunch, my team and I continued to work on getting Xen working properly. We decided to take a more systemic approach by setting up some basic monitoring tools. At that point, Nagios was still a relatively new kid on the block, but we figured it would be worth giving it a shot.

We spent the afternoon configuring hosts, services, and alerts. It’s funny how things like nagios.cfg can quickly turn into a tangled mess of dependencies if you’re not careful. By the time we were done, we had a basic setup that could notify us whenever something went wrong with our servers.

The Evening Reflection

By 5:30 PM, I was finally able to call it quits for the day. As I walked out of the office and back towards my car, I couldn’t help but think about how much things had changed since the days when sysadmins just managed physical machines. Now we were dealing with virtualization, distributed systems, and even early forms of cloud computing.

But as someone who’s been in tech for a while now, I realize that this is what makes it so exciting. The field is always evolving, and you’re constantly learning new tools and techniques to solve problems. Today was just another day, but every single one of them has shaped my career and given me valuable insights.

So here’s to March 10, 2003 - the day I spent debugging Xen hypervisors while dreaming about a better sandwich place down the street.
