[ANN] Collaborative Curved Space Explorer in Croquet
by Nikolay Suslov 14 Dec '09

14 Dec '09

Hello, Happy to announce, that the first version of Collaborative Curved Space Explorer - CCSE SDK 1.0a is out! Collaborative Curved Space Explorer (CCSE) - is viewed to be in future the full-featured multi-user toolbox for exploring the structure of curved spaces in 3D (based on Croquet <http://www.opencroquet.org/>) with real-time rendering in curved spaces. Jeff Weeks originally developed (and continue developing now) the application Curved Spaces<http://geometrygames.org/CurvedSpaces/index.html>for exploring and rendering curved spaces in real-time using C language.CCSEis actually the port of it main part into Smalltalk and Croquet. Thus it allows to run complex time-based simulations and achieve a very deep level of collaborative interactions. More information and screen-shots here: http://nsuslovi.blogspot.com/2009/12/collaborative-curved-space-explorer-v1… Croquet Source code: http://jabberwocky.croquetproject.org:8889/CCurvedSpaceExplorer.html Open Cobalt support: http://croquet-src-01.oit.duke.edu:8886/CurvedSpacesInCobalt,html Ready-to-try distributions with CCSE included: 1. Krestianstvo (on russian)<http://www.krestianstvo.ru/sdk/Krestianstvo1.0a.zip> 2. Open Croquet 1.0.25 SDK <http://www.krestianstvo.ru/sdk/CCSE/CroquetSDK1.0.25-CCSE.zip> 3. Open Cobalt R26 alpha SDK<http://www.krestianstvo.ru/sdk/CCSE/opencobalt-1.0alpha1rc26-ccse.zip> Happy exploring! Thanks, Nikolay Suslov

The Squeakland Tally Contest (win an RC plane with video)
by Timothy Falconer 08 Dec '09

08 Dec '09

Hi everyone, As we prepare for our two month Etoys publicity drive (starting November 1st), I'd like to make things a little more interesting. Let's have a contest. The winner gets a brand-new HobbyZone Super Cub LP with a lightweight Fly Cam One attachable video camera, shipped anywhere (that's legal) in the world. I'm personally donating both. The plane is very fun, and very easy to fly. Also, if you win, you'll be able to do this: http://www.youtube.com/watch?v=iiNxzXixlOc Here are the rules: 1. you must be 18 years or older to enter the contest, or have the signature of a guardian or parent. Proof will be required upon winning. 2. you must guess three tally totals as they will appear at midnight, New Year's Eve, as the Times Square ball drops in New York City. The tally totals are: a. Squeakers (number of people that have signed the squeaker list) b. Accounts (number of people that have signed up for a showcase account) c. Projects (number of publicly visible projects on the Showcase) see: http://squeakland.org/tally 3. Lowest score wins. To determine it, subtract your guesses from the corresponding new year's value for each total, then add the absolute value of the each difference. Example: squeakers ... joe's guess (5000) ... new year's value (4500) ... abs diff (500) accounts ... joe's guess (3000) ... new year's value (3500) ... abs diff (500) projects ... joes guess (1000) ... new year's value (7000) ... abs diff (6000) score = 7000 4. These bonuses will apply: a. subtract 500 from your score if you're the last publicly visible project in 2009 b. subtract 300 from your score if you're from the top NON-USA country in the list at new year's b. subtract 200 from your score if you're at the PURPLE level at new year's d. subtract 100 from your score if you're at the BLUE level at new year's see: http://squeakland.org/showcase/ranking.jsp 5. Initial guesses need to be emailed to me before November 1st starts (midnight) in New York. 6. You'll be allowed three "mulligans" before December 1st where you can change any one of your guesses (one per mulligan). 7. Each mulligan will enact a 100 point penalty, which will be added to your final score. 8. Any obvious attempts at cheating will disqualify you. (Adding Squeakers or accounts yourself, reposting duplicate projects, etc.) 9. Disputes will be decided by me. I'll try to be as fair as possible, though I suspect some will see things differently. My plane, my call. 10. The winner will hopefully agree to send some fly-by video of a "Squeak if you love Etoys" sign, that we'll send, which we'll later use on the Squeakland website. Anyway, I hope this remains friendly and fun. The trick, of course, is making good guesses. A few hints . . . * we currently average about 300 web visitors a day, some new, some returning. We've peaked at 6000 web visitors in a single day. * the peak was because of a magazine article. We *will* be seeking multiple magazine articles and other forms of publicity during this time. * the addition of multiple languages on the website will greatly increase our possible audience * we will have "tell a friend" functionality to allow for some social networking, including facebook, twitter, and blog buttons for individual projects * schools will create multiple accounts, usually in one shot (I just now saw 14 accounts from the same school create accounts). So ask yourself . . . How many people do you think like Etoys in the world? How many can we reach before the end of the year? How many new people will we reach before the end of the year? How many will create accounts, or share projects? I've already made my three guesses (though I can't win), which will remain private like everyone else's. All will be revealed on New Year's Day. Have fun! Tim -- Timothy Falconer Squeakland Foundation http://squeakland.org 610-797-3100 -- "Intelligence is what you use when you don't know what to do." ... piaget

Generating list of tiles
by Bert Freudenberg 08 Dec '09

Here's the scripts I used to create the list of tiles from their help texts. One outputs HTML that I copied to FLOSS Manuals, the other generates a list suitable for a database that Tim might use to provide translated online-help on the website. - Bert -

---------- Forwarded message ---------- From: Gerald Ardito <gerald.ardito(a)gmail.com> Date: Sun, Dec 6, 2009 at 6:31 PM Subject: [IAEP] Sharing EToys projects To: iaep <iaep(a)lists.sugarlabs.org>, olpc-open <olpc-open(a)lists.laptop.org>, "server-devel(a)lists.laptop.org" <Server-devel(a)lists.laptop.org> Hello. I am working with 140 5th grade students who are using XOs (mostly) and netbooks with SOAS. About 50 of them are using Etoys to create projects. I am trying to find a way to share them with their teachers and each other. When I try to upload them to a Moodle course and them download them, the downloaded files can't be read by EToys. Any ideas? Thanks. Gerald _______________________________________________ IAEP -- It's An Education Project (not a laptop project!)

squeak if you like etoys button
by Timothy Falconer 07 Dec '09

07 Dec '09

Hi folks, Try adding this to your favorite webpage: <iframe style="border: none" src="http://squeakland.org/squeakers/squeakerButton.jsp " width="270" height="143"></iframe> We'll be promoting this, along with it's static cousin at: http://squeakland.immuexa.net/linking/ Want to make sure the flash button (the first one) works on many browsers & websites before going public with it. And yes, I know Flash doesn't work in various places. I'm asking to test this button in the places where Flash works (aka, anywhere you can see a YouTube video). Thanks, Tim -- Timothy Falconer Squeakland Foundation http://squeakland.org 610-797-3100 -- "Intelligence is what you use when you don't know what to do." ... piaget

French teachers start using EToys to teach technology in school
by Séverin Lemaignan 07 Dec '09

07 Dec '09

Hello everyone, I drop you a short mail just to report on last Saturday training session that we've been organizing with the French Planete Sciences association for technology teachers from the region of Toulouse. About 15 of them attended, including people from the Teachers college of Tarbes. We were using a special Squeak image based on EToys 4 with extensions to control external electronic boards (including the Arduino board). People had very positive comment on their experience with Etoys and its possible connections with the "real world", especially since robotics is now part of the official curriculum in high-schools in France. Details (in French) and a couple of pictures here: http://www.planete-sciences.org/robot/boiteabots/index.php?option=com_conte… Cheers, Séverin

FFI bug
by Ricardo Moran 07 Dec '09

07 Dec '09

Hi guys I found a bug in the FFI installation of the etoys image. ByteArray>>#structAt:length: throws #externalCallFailed (the method has category nil, which I think is wrong also). I replaced it with a more recent version from the FFI package found in Universes and now is working: ByteArray>>structAt: byteOffset length: length "Return a structure of the given length starting at the indicated byte offset." | value | value := ByteArray new: length. 1 to: length do:[:i| value unsignedByteAt: i put: (self unsignedByteAt: byteOffset+i-1)]. ^value Cheers!
