Sucking Less Every Year A trail of thought that had been on my mind for a while

Quoting directly from the post

I've often thought that sucking less every year is how humble programmers improve. You should be unhappy with code you wrote a year ago. If you aren't, that means either A) you haven't learned anything in a year, B) your code can't be improved, or C) you never revisit old code. All of these are the kiss of death for software developers.

1. How often does this happen or not happen to you?
2. How long before you see an actual improvement in your coding ? month, year?
3. Do you ever revisit Your old code?
4. How often does your old code plague you? or how often do you have to deal with your technical debt.

It is definitely very painful to fix old bugs n dirty code that we may have done to quickly meet a deadline and those quick fixes ,some cases we may have to rewrite most of the application/code. No arguments about that.

Some of the developers i had come across argued that they were already at the evolved stage where their coding doesn't need improvement or cant get improved anymore.

• Does this happen?
• If so how many years into coding on a particular language does one expect this to happen?
