Inspiration is perishable

July 8th, 2009

I am following the 37signals blog ever since I kinda randomly stumbled upon their Getting Real book. If you never heard about them, definitely check out the book, is a very common sense approach to managing product development in the age of Internets. On this post I was really touched by one remark: Inspiration is perishable. The ideas you have can linger in your head for a long time, but the inspiration for it fades quickly. So don’t postpone it, by the time you get to it you’ll only deliver a pale image of the original idea. Do it when you’re pumped up and thrilled by it.

I reckon I’m a procrastinator deLuxe, but I have to agree. I know the difference between working at 2 am. and not feeling a bit tired when I’m excited about my work on one hand, and the damp feeling of exhaustion that drags you to watch some stupid TV show at 6 pm because I’m bored with the current project on the other hand.

Things I know now: blogging can get you into a email ponzi scheme

I got tagged by Adam Machanic. Although my blog looks like a DBA blog, I am a pure breed developer, so here is what I know now:

You can’t fix what you can’t measure

Successful projects dedicate quite a large amount of resources to instrumentation, profiling and monitoring. Anywhere between 5 and 10% of the used resources should be an acceptable margin to run code that generates logs, reports performance counters, monitors responsiveness, aggregates and consolidates run time data. I cannot stress the importance of properly instrumenting your code to support this. It has been said before that any optimization or troubleshooting should start from measurements, not from guesswork. Your duty is to put those measurements in place, expose information your users can rely on in order to make informed decisions. Don’t cut corners and eat your dog food: use the instrumentation you added to troubleshoot problems, don’t fire up a debugger and start stepping through the sources. If you cannot figure out the cause of a problem from the tracing and logs, your customers won’t be able to do it either. Nor will you be able to troubleshoot on site at a customer deployment.
