Laura Thompson has a quick post to her blog explaining one simple fact that all developers (or really anyone even loosely related to computing systems) should remember - all systems suck.

I’ve been thinking a lot about this idea lately. I’ve spent a lot of years as an engineer and consultant fixing other people’s systems that suck, writing my own systems that suck, and working on legacy systems, that, well, suck. Don’t let anyone fool you. All systems suck, to a greater or lesser extent

She presents her "slightly jaded" points of view about legacy systems, current systems and ones yet to be built nothing that, no matter how impressive and well-planned out they are, they'll still suck (some maybe just a bit less than others).

Here’s the punchline: sucking is like scaling. You just have to keep on top of it, keep fixing and refactoring and improving and rewriting as you go. Sometimes you can manage the suck in a linear fashion with bug fixes and refactoring, and sometimes you need a phase change where you re-do parts or all of the system to recover from suckiness.
