Interesting discussion so far about vi/emacs vs IJ/Ecl/NB. There were
lots of arguments concerning the PERSONAL productivity of a single
programmer.
For my part, i personally stick to IJ, i used that since 2001 (with a
1-year intermezzo in Eclipse) and has since not disappointed me.
Previously i did not object if someone else used notepad/vi/emacs until
I experienced working with them in a team:
The problem i see is you have to look at the productivity not only of a
single programmer but rather the combined productivity of a whole team.
Some anecdotes supporting this:
In one of my teams we had a single programmer insisting on using vi
only. He was coding javascript with proclaimed 3 years of experience.
After his checkins I opened IJ and saw 2 yellow and 3 red markings.
Without knowing javascript i knew this was wrong and ideed those were
errors, popping up in some corner-cases. Also some html tags were broken
(like <div><span></div></span>) which would be trivial to detect and fix
with a decent editor.
In other situations a 10-person team coding Java everyone wrote
auto-generated hashCode/equals methods, everyone was used to it. Except
the "hardcore" guy wrote them by himself leading to bugs and furthermore
he was dragging everyone down, because everyone had to re-check his
manually written methods for errors, while they could rely on most
auto-generated ones being correct.
Also the practical method of keeping final immutable fields public
rather than private with a getter becomes unhandy if you cannot rely on
the fact that everyone in the team can trivially apply "encapsulate
fields" as a refactoring.
Convulated Naming conventions become obsolete if the IDE renders
different types in different colors. (members, local variables,
interface impl etc..).
The same holds true for many other "modern" coding techniques which rely
on good IDE support.
my conclusion: In a team a single person not using top-notch tools can
potentially harm the productivity of everyone.
