if you try and say that the entire world is wrong in how it writes
software, and only software specificly written for the Sugar environment
should be available to the children, you are doing them a great
it's fine to produce an alternate approach, but to bet-the-business on
that approach with no fallback is betting that you know better then the
rest of the world. it's possible that you are right, but not very likly.
however if you allow for compatibility you have a fallback.
many people have pointed out the limitations of the journal approach, and
problems with not naming activites and files. yes it's easier to get
started if you don't have to deal with confusing matters like directories,
but as more documents are created a flat namespace for them will get
overwelmed (be it a time-based journal, or a single layer home directory)
you are optimizing for the beginner so much that once they have used the
system for a short time it will no longer be suitable for them.
dom't make the training wheels for beginners so ridgid that the kids can't
remove them as they learn more.
As for your arguments about object oriented programming vs functional
programming, opject orientation has it's place, but there have been a lot
of evils foisted on us over the years under the banner of Object
Orientation. just becouse an idea has merit doesn't meant that any
implementation of that idea is automaticaly good.
