Re: [amibroker] Re: Study Charting dare I say bugs..., AmiBroker Email List Archive

Hello,

For correctness sake: AB is NOT one man band.
There is Marcin doing 99% of support tasks. Plus I do outsource
bookkeeping and some other "side" tasks.

What is one-man is AmiBroker core development.
And it will stay that way for various reasons, with main reason
being that adding 2 more developers for core development
would SLOW DOWN the development and the quality
would go down hill, no matter how good these developers are.
These are facts of life. I was working in various developer teams
in the past starting from 3 people ending at 40 developers
and adding developers only adds problems. The only
way to work in a team in efficient way is to have *separate* programs
to develop (they can communicate between each other).
Sligthly less efficient (but still OK) is to have plugin approach
with well defined interface. The plugin approach is already implemented in AB.

Programming is NOT equivalent to homebuilding.
Programming is rather like composing music. At least for me.
Did you see lots of music written by more than one composer?
(even if many people appear on the "credits", usually the core idea is the work
of one man).

Best regards,
Tomasz Janeczko
