[Etoys] How to cut a segment in 5 equals parts...
by Hilaire Fernandes 18 Jan '08

...without measure It can be done using the central symmetry. This video shows it in the DrGeo2 interactive geometry canvas: http://squeak.ofset.org/drgeo/5parts.ogg The Undo/redo stack is used to replay the construction. The figure is loaded from a DrGeo1.1 xml file. Hilaire -- http://blog.ofset.org/hilaire Smalltalkers do: [:it | All with: Class, (And love: it)]

[Etoys] Project loading trouble
by Karl 14 Jan '08

14 Jan '08

The kind people at OLPC sent me a XO and the last week has been busy getting familiar with the system. Anyway, I updated it to the latest dev build (1525) and can no longer load projects into the Etoys image. Anybody else experiencing this ? Karl

[Etoys] publishing Etoys projects as individual activities?
by Bryan Berry 11 Jan '08

11 Jan '08

Hey guys, The developers in Nepal have put together some really cool activities. http://olenepal.org/activities/epaati_bundle1.zip Ties Stuij also put together a nice little Etoy for Nepal in just a few days http://stuij.se/etoys/MoneyBrother.008.pr I talked w/ Walter the other day about Squeak activities and he spoke about the need to put individual Squeak activities into individual bundles. That makes sense to me. At the same time I really like the tabbed interface that the OLE Nepal team came up. Please take a look. Would it be possible to keep the individual Squeak activities and particular image files separate but relate them? that way we could still have cute interfaces that are easy to follow but not gigantic squeak image files. Also, is there a project space for E-paati on dev.laptop.org yet? I saw the hosting request that Luke submitted 2 weeks ago but I don't see it on http://dev.laptop.org/git

[Etoys] Slightly familiar with Squeak, confused by EToys & OLPC, Please give ne some pointers!
by Thomas Porter 08 Jan '08

08 Jan '08

Hello! I just got my OLPC a few days ago and am having a great deal of fun exploring it. EToys (or Squeak at least) is one of the more familiar areas in the OLPC to me, but I have some real conceptual difficulties: 1. I understand Squeak uses images, so that when I 'save & quit' from a squeak session, I am saving my current state in the images file. 2. I don't know much about EToys, but I assume there is some way to export projects so they can be shared with other EToys users in a way that is perhaps like filing in changesets or installing packages from SqueakMap?? 3. If I understand OLPC setup properly, the EToys image is read only, hence the instructions in http://wiki.laptop.org/go/Smalltalk_Development_on_XO to copy the image & changes files to a location where they can be updated. This is only needed for developers, or people who want access to the full set of Squeak tools like the class browser, etc. 4. If I understand the OLPC even a little bit, Activity state is saved in the datastore, and Activities can be resumed. My basic question: How do the ideas of a. Squeak images being read only, b. EToys projects, and, c. OLPC Activities fit together? - If I make changes to a Squeak image that would require a 'save', would I be correct to assume that stopping and resuming my EToys activity will NOT save these changes, but would be like starting my Squeak session over? - If I have multiple EToys Activities listed in my Journal, do these represent different Squeak sessions or states, and is each independant of the others and independantly resumeable?? To me this would involve saving a set of image and change data somewhere for each activity, or at least deltas against the original image & changes. Please correct me if I am wrong, but aren't change sets just for code changes, or can they save what I would call IDE state like the presence and position of workspaces, transcript windows, class browsers, etc.?? - Assuming I only have the Read Only EToys images and change files, f I start working on a new project in EToys, or even make a change as minor as changing the speed of the little car, are these changes saved when I stop the EToys Activity, and if so, how? I apologize in advance for these newbie questions, but I'm really missing some connections here and have not found a lot on the laptop.org wiki about the details of how EToys is implemented on the OLPC and how it interacts with the sugar environment. Thanks for all the hard work on the OLPC, I think EToys really stands out as one of the coolest apps on the OLPC. Tom Porter
