If teachers/users could make a group or curriculum of projects on the site, we could rank from the refs to projects. I tried to rank a few project, but it's quite hard to do. There are to many things to consider. I'm not a teacher, so for me to rank appropriateness of a project for a classroom situation is not really realistic Karl > > I hope that teachers who encourage their students to upload projects > will *only* allow sharing if their student provides an "About" flap, > or some intro/explanation of the Etoy and some instruction on where to > start, the aim of the project, etc. The most beautiful simulation of > something will fall completely flat with someone if they have no real > idea of what they are looking at or what the script they are playing > with is meant to do.

by Timothy Falconer 09 Jun '10

09 Jun '10

Hi everyone, As before, we'll be having a software meet on the IRC freenode channel #etoys at 19:00 GMT (3pm ET, 12 PT). You can also attend by clicking "chat" on squeakland.org. It might be helpful to watch the two preview videos here: http://squeakland.org/resources/audioVisual/ Also, have a look at the current Etoys 4 roadmap: http://tracker.squeakland.org/browse/SQ?report=com.atlassian.jira.plugin.sy… Take care, Tim

popups in project-info
by Scott Wallace 31 May '10

31 May '10

Hi, Tim, and all, Attached is a fileout providing changes to the project-info dialog as requested for the benefit of the "showcase" on Squeakland.org. Basically, the "project info" dialog now contains three "enumerated" items, "Subject", "Age", and "Region". These three are all governed by pop-ups (in local language) rather than by type-ins. The results are included in the project manifest. Important notes: (1) It is essential that this be filed in to an image updated at least through update 2246PolygonFix-kfr. If filed in to an earlier image, subsequently loading updates will clobber some of the changes provided here. (2) Yoshiki is also modifying code in the EToyProjectDetailsMorph area in this same time-frame, so integration is likely to be necessary before our two fileouts are published. (3) There are a few obvious rough edges which someone may wish to tweak, though I don't know of any show-stoppers. For example, this has always been an English-only dialog, but now that the field names are localized, there may be layout issues in some languages (once translations are available.) Also, for the pop-up fields, if they've never been set they show as blank, whereas once they've been set to "(none)" (equivalent to blank) they show the text "(none)". Probably we should always show "(none)" when values for these three popups have not been supplied. Also, since some of the fields are now type-in and some are pop-ups, perhaps some UI convention (slight color difference?) should be used to hint at whether a field functions as a type-in or a pop-up. (4) This turned out to involve quite a bit of code, most of it written with a fever and at very late hours. So there's the distinct possibility of errors. I did test it briefly and it seemed to work as I expected. HOWEVER: it really needs verification by someone else. (5) The Preamble (please read if planning to test or use): -=------ Change Set: projectInfoPopUps-sw Date: 8 August 2009 Author: Scott Wallace Changes to the project-info dialog, in support of new data desired for the 'showcase' on squeakland.org: - 'Sub-Category' removed. - Subject, Age, and Region are added as pop-ups. - Choices for Subject, Age, Region popups, and corresponding codes, obtainable from web-site. - Project manifest now includes Age, Subject (category,) and Region info. The codes are strings of numbers, e.g. '554' as a Subject code means 'Language Arts' (look in #defaultAgeTriplets, #defaultSubjectTriplets, #defaultRegionTriplets on class-side of EToyProjectDetailsMorph.) - Names of fields are presented to the user in localized form. - Choices for values of pop-up fields are presented to the user in localized form. Notes: - There is support provided for obtaining up-to-date lists of the subject, age, and region alternatives from the web site (see EToyProjectDetailsMorph class updateTripletsFromWebSite) but it is not actually called at this point, out of concern for potential for long delay if connection to web site is slow. - The *region* codes are at present *not* obtained from the web-site (even when the user explicitly calls #updateTripletsFromWebSite,) but rather a 'fake' set of regions, basically the continents, is provided. This is probably temporary. We have no reasonable way to confront the user with a pop-up showing 250 choices. However, as per Tim's request, I have made it a point to include Antarctica in the region list. (Tim: look at method #defaultRegionTriplets for the current point of departure, if you want to adopt that, temporarily at least, on the web site. And/or of course change any defaults as needed. ----------- Cheers, -- Scott

By mutual agreement among Bert, Yoshiki, and me, we decided to push the latest fixes embodied in SQ-88, SQ-154, and SQ-257 to the etoys4.0 update stream today. This will make it easier for more people to test, and we still have time before squeakfest/brasil to fix any issues that may arise. Cheers, -- Scott

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

The only fix after the 4.0 release is this so far: https://dev.laptop.org/ticket/9709 The new 4.0.2337 rpm should work both on an "old" XO and on the new XO-1.5. In particular the folks who got a 1.5 beta machine: Please test, and report back! Upgrade your machine to the latest firmware and OS, then install the Etoys rpm and XO bundle. Even saying all is fine is good, otherwise I'll have to assume nobody is testing. Thanks! - Bert -
