Hi Jamal -- well thanks for the compliment -- but I thought your interpreter
was a well chosen project, in which you took what was already out there and
apparently got it working with features useful for blind developers. I
haven't seen the code or tried it out as yet, but given your track record
I'm sure it is a good piece of work. I mention the selection of project and
selection of code base as I in times past made the mistake of diving into
something without first checking or considering what was already out there.
So that shows you have business sense as well as tech savvy.

Thanks, Laura -- with your background, that's particularly meaningful!
