Support lessons learned

It’s been quiet around here for the last while. I’ve been spending my time and energy on some side projects that don’t really pertain directly to the art of programming. They do, however, have a degree of interaction with a programming community….and that’s where it all goes sour.

I’ve had two run-ins with this programming community over the last few months. Both times it has been related to support. I’ve been playing around with creating things for a flight simulator (www.flightgear.org to be precise). One thing that I have been working on was the modeling of an aircraft flight and autopilot systems. Again, I hoped that some of the elements of programming a simulated computer system would possibly lead to some greater development enlightenment, but the ultimate desire was to have a great simulation of this specific aircraft.

In just the last couple of weeks I ran into a problem with the graphics functionality of the software. I’m still not sure what it is. FlightGear is open source so I could dive into the codebase and figure out what is going on. I have absolutely zero desire to look at a bunch of C++ graphics code though. Since this feature is a fundamental framework support piece for what I am trying to do what I really want is for it to just work or a fix to be made. My mentality is that of yours and my mother; I don’t care how sausage is made, I just want to eat it.

With that in mind I log a defect with all of the details that the project asks for in a defect entry….and then I wait. A few weeks, and nightly builds, later I update to the latest build and the problem still persists. So I update my defect. I’m already thinking about my options for moving to another flight sim, but finally someone responds to the defect.

Lesson 1: The longer you wait to respond to defects, the more likely the defect reporter is to go find another tool/system to replace the problem system.

The first response to the defect is request for me to turn some stuff, which I vaguely recognize the meaning of, on and off. So I go looking in menu items, the project wiki and other things to see if I can figure out how to trigger these changes. Nothing. I’m stumped so I report back as such.

Lesson 2: No matter how close you are to walking away, communication is always helpful.

The next messages follow a similar pattern but also include statements like “see the wiki”, but don’t include links or specific topics that I should be referring to. So, again, I stumble around looking for the mysterious piece of information that is supposedly included in the wiki. I find nothing related to that topic. I end up digging around and eventually finding something that works the same as I was originally told to use.

Lesson 3: If your support technique is to send people to documentation to help gather debugging information, that documentation had better be both comprehensive and complete.

I’m told to increase the logging verbosity and “send the console output to a file”. I get the verbosity jacked up without any problem but I cannot get the output into a file. After a fair bit of research I find out that sending the output to a file isn’t supported in Windows for this application. Well isn’t that just nice.

Lesson 4: If you know you’re going to be supporting different platforms/environments you need to be 100% sure that your support tools and techniques work equally well for all of them.

I have been told that I should reconfigure my hardware to ensure a known baseline. My hardware is not abnormal. In fact, it is using up to date drivers and out of the box configurations.

Lesson 5: Asking for hardware configuration changes makes you look like you’re flailing and unprofessional.

So after 2 weeks, and about 6-8 hours of effort, I’m absolutely no closer to a solution that I was before.

Lesson 6: If it takes the user more than a few minutes to start the process of gathering debug information for you, then it is you (the project/developer/team) that has failed, not the user.

Before anyone says “Oh, it’s open source so you could just go fix it yourself” everyone needs to start remembering one thing; You’d never do this on a project for your employer. If you did you’d probably not be long for employment with them. So why is it any different in OSS

Lesson 7: An OSS codebase is not justification to throw good development and/or support practices out the window.

How come you don't end your blogs with "I'm the Igloo Coder" anymore?

It's hard to remember to when you only blog a few times a year.
