During the summer I started a difficult but important journey to reorganize my life. The first step was organizing my daily tasks. I was successful, but becoming productive again has created new issues. When you change from trying to do everything to doing what’s most important, you need to decide what important means. Figuring this out for myself has proven difficult. I still don’t have all the a...

One of the best things about working in the software business is the high rate of change. Not only do we work with machines that radically change in capability every few years, but new techniques and technologies are constantly appearing on the scene. It is a fascinating new frontier that never gets dull. One of the worst things about working in the software business is the high rate of change. If...

I’ve been fortunate to take some serious down time during the summer. After working pretty much non-stop for ten years, things have piled up. I took some time to rest, then got to work on some personal projects that have been neglected far too long. What I’ve learned, however, is that it takes more than time to get things done. After about a month, pretty much all I’d achieved was completing a cou...

Or: The Most Impressive T-SQL Script I’ve Ever Written I was recently working on a new application. After three months in the field, users were starting to complain about performance issues. We had done some limited performance tuning for the first release, and more as part of the second release, but new issues were popping up as more data got entered into the system. We could have continued fixin...

For the last ten years, if you had asked, I would have told you with some conviction that a “critical path” is a kind of test script that tests the essential functionality of a system. If the app passes it’s critical path test, I would have said, it may not delight users, but it’s unlikely that they’ll storm your basement with torches and pitchforks. It came up at work during a discussion about in...

I’ve taken a big step in my career. I’ve become a software consultant. The decision to leave my job of three and a half years wasn’t an easy one. I was working with some fantastic people, building the best software we could, but at the end of the day I wasn’t learning. The work was challenging, but the challenges were mostly non-technical. In this business, if you’re not moving forward you may as ...

I was conducting technical interviews recently for a senior developer position. I like to talk about a bunch of things, but there is one question I particularly enjoy asking each candidate. Write an implementation for this: 1234int Average(int a, int b){} It’s a great question because it’s a simple problem, and anyone that comes through the door should know the formula without having to...

We did one of our monthly releases at work this week. Releases can be stressful and frustrating, and take a lot of methodical preparation to get right. It can be thankless work too; the only time a user notices a release is when it goes badly. We do our releases early on a week day to minimize impact, so if anything does go wrong, there’s not many bodies around to help out. It’s not much fun, but ...

I’m working on the code that parses VCalendar data so that it can be processed. I’m copying the data I care about into a simple data structure that can represent a calendar request in any format. Any logic that interacts with calendar requests would use this internal structure. I want it to be simple, only having the stuff that I need, but I don’t want to completely re-invent the wheel either, so ...

My company runs a 24/7 site with a substantial number of users and connections to partner systems all over the world. We do what we can to make the system fault tolerant, but problems can still appear at any time of day or night. Ideally we would have a technical support team that’s staffed around the clock, but that not in the cards for now. We used to have a system where anyone that could f...
