Hello all,
 
I feel the need to shed some "light of reality" on the takeover discussion.
Many people have put forth their ideas as to how a bug fix might be made to the
MacApp 3.0.1 code base by an external developer.  More than one person has
suggested that these fixes could be easy and relatively localized for "easy
testing".  Within the last day or two somebody has actually recommended a "by
sight" verification of bug fixes.
 
Now let me speak from a point of experience.  We (the MacApp SQA team) learned
something very important during the MacApp development process: changing any
MacApp code can have some unexpected side effects.  We did let an alpha release
of MacApp go to our internal source code management group (the last stop before
sending a release out) *once* with a last minute "by sight" bug fix in it.
Three engineers looked at the fix and "ok'd" it.  That fix resulted in a new
crashing bug that developers would have found rather quickly.  The lesson
learned - we always did a full testing cycle for each release of MacApp after
*every* bug fix was in.  A full testing cycle is an 8 person-week job.
 
I say all of this not in the attempt to derail or undermine the takeover
discussion but to let people know just what is involved in a "simple" or not so
simple bug fix to MacApp.
