Thanks again for your proposal - I'm sorry it was not selected.

Well, for this project, it is simple: The coding mentor for the project,
Eli, is more interested in Python, so I suggest that the Font Editor
activity be written in Python.
But generally, I think that to decide if a new Activity should be in python
or js, it is wise to the end users must be kept in mind. It seem that the
majority of Sugar users are using the XO laptop, and today there are very
few users of Sugarizer (although no one really knows how many there are,
but it surely can not be over 10,000, whereas it seems to me personally
likely that there are still 10,000 active Sugar users.)
Mobile is going up up up right now, and at the moment, the Sugar community
has developed Sugarizer as a way to bring Sugar Activity designs to any
child who wants to learn with them... But it still in a relatively early
stage. So it is probably best to write a standalone web application for
kids, that can be packaged for Android, iOS and Sugar; Jamie's decision to
do this seems instructive.
Even for the world's children, per

You don't hear this term much any more, but when I was a boy (I'm 33 now)
then the term for a "desktop" before the 90s "wintel" era was a
"micro-computer." (In fact this is where the company name "Microsoft"
originates from; initially that company was called "Micro-soft" ;)
This name made sense in the 70s and 80s because back then, the
https://en.wikipedia.org/wiki/Minicomputer was as dominant and professional
and serious and productive as desktop/laptops are today; like the PCs in
the above graph, they ran a curve up from the mid 60s to the mid 70s, and
when were at their peak, the earliest micro-computers were kind of silly -
https://en.wikipedia.org/wiki/Apple_I is from 76, just look at it :)
But then mini-computers were in terminal decline, down to the late 90s when
less savvy people spent a lot of money bailing out their failing dot com
start up's crappy software by using their VC money to buy bigger
mini-computers ;) Meanwhile more savvy people built server farms out of GNU
servers on cheap commodity PC hardware; the reason Google's brand colors
are what they are is because the first server racks for those cheap PC
motherboards were made out of the similarly colourful lego bricks ;) And
now today, minicomputers are totally gone, I think - although mainframes
persist. Maybe someone here knows of minicomputers in use today? :D
Anyway. The point is that all desktops and laptops - from Windows on down -
are going away, and likely much faster than minicomputers went away. So I
don't think it makes much sense to invest too much in desktop systems, no
matter what language they are written in.
About 3 years ago I helped initiate an 'advanced' font editor project, that
started in Python, and then after a year of prototyping, was restarted in
still isn't really useful, and partly that's because so little existing
of 'foundational' parts themselves. We understood at the time we'd be
moving our starting position back, and today a lot of the foundational
parts needed for a web based font editor now exist :) At the time I
But in learning about the history of OLPC and Sugar, I have been quite
astonished to learn about Squeak and EToys. I think it would be exciting to
write a font editor in Squeak, and it seems Squeak is very capable of
running on any platform - even inside web browsers.
So, Mredul, since in a prior private email you said you won't be able to
contribute to the effort with out the GSOC funding, I do recommend spending
some time learning about Squeak. I think you'll get a lot of value out of

Yes, I agree, there should be a tool for adding points, a tool for moving
points, and a tool for removing points.

I agree, although the guidelines should not be square, like graph paper,
but rather based on horizontal alignments and on vertical 'cadence.'

(Paint is a raster graphics application, whereas fonts are vectors.)

Me too :)
