It's interesting to note that a big reason ( ) dominate in Lisp here is that pg adopts the FP habit of short var names. If anything this is probably just a measure of the tendency to use long vs short name - mainstream OO practice encourages the former. It would be interesting to rerun the heatmap for Lisp with a typical CLOS program. I think you'll find that ( ) no longer dominate.

EDIT: And in fact here's a heatmap of core.logic (1K LOC) which is fairly OO-ish in its design - http://twitpic.com/6hwj88. ( ) are strong but do not dominate everything.

UPDATE: And here's a 1.4K LOC Clojure program, core.match http://twitpic.com/6hwo8w/full. ( ) again do not dominate.

Interesting to note the difference between C and C++ with regards to the '*' and '&' keys. I know there is a lot of raw pointer and address usage in C, but I'm surprised at how little these keys show up in C++. It's good to see that people are taking advantage of smart pointers ;) (It's subtle though, so I could be reading too much into it).

Seems odd that are said to be used more in C than in C++ (templates).

The title is misleading. They just extracted character frequencies from source files which fail to capture 'Delete', 'Shift', 'Ctrl', 'Alt', etc keys. Even has Paul Graham name at the end, as if 'Look, this is totally legit!'

Well, Ctrl and Alt aren't related to the programming language (more the editor or OS) and neither is Delete.

Shift is, but that could have (should have IMO) been extracted from the character frequencies in the source files...

It's common to typedef the templated types you use.

ex:

typedef std::tr1::smart_ptr MyClassPtr;

it'd be interesting to see these heatmaps in some sort of normalized way. for example, 'e' is the most common letter in english, so its the most commonly used letter in these programming languages. it'd be very interesting to see, for example, this heatmap with the intensities divided by each letter's frequency of use in the English language, or across a large set of data including a lot of different programming lang…

Except for Lisp, of course, where ( and ) are more common than e.

This is not true. See my other comment on this thread. Dominance of ( ) only reflects a particular coder's naming convention.

Lisp: http://dl.dropbox.com/u/2196687/lisp-keystrokes.png

My experience with Lisp is minimal, and I'm a Vim guy, so I may be totally wrong about this, but...

Doen't nearly all serious Lisp developers use Emacs? And doesn't Emacs have piles of shortcuts for wrapping/unwrapping/manipulating s-expressions? I'd imagine that the resulting number of parens is wildly different than the number originally typed.

Can any experienced Lispers comment on this? Where can I find a cheat sheet of such shortcuts?

Earlier quoted context omitted.

For this reason, I think it would have been more interesting to ignore the alphabet keys and just heatmap the rest.

But then you lose the impact of the entire set of reserved words. At the point of ignoring the entire alphabet, you're looking at developer preferences for spacing and operators. Might be a nice sidebar to the existing heat maps.

What would a programming language look like if it was optimized so its reserved keywords used mostly home row letters (and, in Unix tradition, preferably alternated left/right hands) and operators without shifting? This would be tough, since the home row only has one vowel: a.
