I just realized a nice anecdotal metric due to some CodeAssitor work I did today.
I noticed when I sat down to work on some regular expression stuff for CA that it was ~1:30 in the afternoon, for some flakey reason, my brain made a mental timestamp. When I finished the feature I was working on I noticed that the time wasy ~5:30.
What's interesting is I completed one whole feature (or at least got the feature from 0 to code complete... which means there hasn't been extensive testing), and quite literally nothing else (no washing breaks, no coffee reheats, no email checking, nothing but code.
The day previous I worked on adding the 0-1 quantifier (?) to Scintilla's basic Regular expression code (RESearch.cxx), and got that feature code complete... unfortunately I didn't notice the time and I was very distracted watching the Chilean miners get free (CHI-CHI-CH LEI-LEI-LEI!), and was doing numerous other things.
Anyway... So I sit down in front of my computer to work on some CodeAssistor stuff and notice the time is 1:34. I check the Scintilla Mailing list to see someone had posted a reply to my ? quantifier work, and someone had. Here is Philippe's email:

Yes, if it works... For this, you should:
- Fix indentation...
- Add documentation of the new operator in the documentation at the start of the file.
The semantic of the operator isn't clear. From a quick glance at the code, it looks like
it is used in place of * with the meaning of 0 or 1 occurrence of the previous token, not
as a modifier to make an operator non-greedy, right?
The latter would be more useful, but it much harder (if possible) to inject in the current
engine. The former can still be useful, though...

1) added the lazy operator functionality
2) did up the spacing how he wanted + documentation
Anyways, it was 5:27 when I finished.
The most interesting part of this endeavor is that you can see just exactly what I accomplished during those 4 hours.
Anyways, I thought this was an interesting piece of data. Especially because I wasn't planning on timing myself, so I didn't change my work effort at all.
Note: its 5:44 as I finish this blog.
