The article is about Six Ways To Write More Comprehensible Code. It makes size points:
- Comment well and often.
- Use sensible names not obscure constants.
- Use variables with descriptive names.
- Do error checking.
- "Premature optimization is the root of all evil." - Donald Knuth
- Don't be too clever.
The article is a nice little bit about writing better code. Personally I rate number 5 very highly, in fact I should write an article about writing better code from my point of view.
