The recovering programmer
The 1969 diagram that became the Internet
On the Recovering Programmer blog, he has a recent entry:
Write Code Like You Just Learned How to Program
http://prog21.dadgum.com/87.html
That entry recently helped save me from going off and wasting a few hours in a few situations at work and on some hobby projects: sometimes you can hard code something and then fix it later when it’s a problem, instead of implementing everything perfect ‘the right way’ to prevent problems, especially when you’ll have to implement it from scratch again anyway, if the idea even works!
