I agree not much different. I started writing code for a living in the early 1990s. How I wrote code then was not much different from how I write code today: using a text editor, write a little, test a little, keep building up working code. I debug mostly with print statements and logs, which is how I've always done it.

I've never liked IDEs and still don't use them. Version control is much more widespread. My favorite was mercurial, but I'm now mostly using git as swiming against the current there doesn't seem to be worth it.
