For those who might not know:
Pippy is akin to IDLE but designed to run with Sugar, the OLPC OS
developed for the XO, an esoteric piece of machinery that's a rarity
in the Lower48, not to mention elsewhere in the world.
I have a lending library with two of them.
I mostly won't lend them to anyone over 10-12 in age as when it comes
to One Laptop per Child, adults take a back seat.

Although Logo/LISP is a correct grouping by language family, Logo is a
far cry from a full implementation of LISP.
Also, J is significantly different from APL, just just in terms of
using ASCII instead of those non-Latin-1 operators, however once again
the family grouping is correct.
I have a paper on J at my website that the late Kenneth Iverson helped
me with, in terms of catching a few errors.
I favor J as my other language besides Python, buying into the premise
that we want a minimum of two languages for projecting around the
campfire (girl scouts or whatever -- boys too sometimes).

Good thing we have C++ though, with Python bindings ala Boost.

Good thing Alan failed to prevent C++. He'd probably never have come
up with C# either.
I enjoyed meeting Alan for 2.5 days, with plenty of breaks, well
treated by The Shuttleworth Foundation, me more as Guido's side kick.
I also came via having given a talk to London Knowledge Lab (LKL),
whereas Guido had recently been a guest of Goldman & Sachs I think it
was (adding a decimal type made Python more usable in the financial
world where the IEEE floating point standard isn't insufficient for
serious accounting work).
Some of the tidbits I learned about Alan:
prescient, as I mention in my blog. I also dig up this paragraph,
perhaps no longer as true as it once was (posted April13, 2007)?
Alan Kay of Smalltalk fame, friend of Seymour Papert of Logo, champion
of One Laptop per Child (OLPC) has become our new keynote speaker
(EuroPython by transmission) and provider of new hope to many a would
be Python learner. That's right, Alan has adopted Python as his new
pet language, or so he told us at the Shuttleworth Summit in London
last April, hosted by Mark (Shuttleworth) in hopes of taking what's
right about the CP4E dream, and adapting it for his home country of
South Africa where it became the Kusasa Project (kusasa.org).
(b) It was more the immersive environment than any specific
implementation that drew his focus and attention i.e. he wasn't
ideologically committed to Smalltalk above all languages or anything
