Nope, it was'nt about JRE vs JDK. Feel free to add an addendum to my comment, prefacing your's with :

ILXO

It is indeed! We can always use extra hands - right now one of the big issues facing us is finding office space before June 18. Another is setting up a trac instance on a server somewhere for keeping track of projects and tasks. And then there are general projects and software development and teaching and the like, and some work on the low-cost laptop act advocacy effort that needs to be researched and done... what sorts of things are you interested in?

Thanks for adding the section on the OLPC Chicago page - one correction I made, though, is that we aren't an official OLPC effort; we're also an independent grassroots group. Mchua 15:35, 27 May 2008 (EDT)

testing new Asteroids

I'd be interested in trying out the new versions. warning -- my week-old laptop pretty much defines my Linux experience. I've spent most of my time on WinTel boxes. But, n00bs generating error-messages are a great test, especially if they dump some of that data back into the wiki....

Question: acceleration/deceleration seemed very sloooow. Is this normal, or one of the playability changes? In other verisons I'm more used to scooting around, then having to brake furiously. ah, it's probably the "sluggish" response you mentioned on the Asteroids page, right?

porting BASIC games to python

>The sort of grab bag that was in 'What to do after you've hit return'. Math and logic games, simulation games.

You might want to check out some of the old books that used to be everywhere; I've got a copy of Tim Hartnells 'Second giant Book of Computer Games" on my work desk. Not work related, I'm sure, but an inspiration.... of sorts.

Online, we can find BASIC Computer Games Edited by David H. Ahl, published 1978

A few more (or repeats?) at http://www.dunnington.u-net.com/public/basicgames/

and more, possibly, withing the Creative Computing Archives

>IIRC someone has started something similar with translating some Commodore 64 BASIC programs to Python.

Mentioned at the bottom of the Pippy page

Re: Implode bug

Thanks for the report! It looks like some APIs changed in the new version of Sugar. I'll see if I can get it fixed later this week. —Joe 04:12, 14 July 2008 (UTC)
