  • Teach this to your manager: At the beginning of a task, uncertainty is highest. Under no circumstances should you give an estimate in ‘man-hours’. Even days is too precise. The first estimate should be in months or years (of course depending on the size of the project). Then, as your insight into the project grows, you refine that to months, then weeks, later days. A vague estimate with a lower and a higher bound is way more useful to your manager than a ridiculously ‘precise’ but highly speculative number.

    This lesson was brought to you by either “Code Complete 2” or “Rapid Development” by Steve McConnel, and by my former manager who wanted projects estimated in minutes.





  • Let’s say “you wouldn’t have noticed there was a problem if there was no mismatch”. But then a few years later that max length gets dropped or increased and suddenly your password, which has always worked, isn’t accepted anymore, because now you’re pasting 2 extra characters.

    I was also not talking about password fields, exclusively. Pasting stuff like customer identifiers or zipcodes into maxlength’d fields also begs for surprises, especially when you can’t see the whole input when you’re done with it.
