nearly tearful success story
by Randy Heiland 26 Oct '05

26 Oct '05

I just wanted to report another successful introduction of Squeak/eToys to a young group of children here in Indianapolis. I began a new Squeak workshop (for 6-8 year old girls) at an after-school community center last night and came away once again rejuvenated about seeing children excited to do something creative on a computer. I say it was a "nearly tearful success" simply because their computer lab was very small so the girls had to triple-up on each computer and take turns and, well, not everyone got as much as they would have liked which generated some sadness. It was just the beginning of this particular workshop and we got no further than the basics, but I can tell that the girls were already very excited about using eToys and I look forward to our remaining sessions. I don't believe the Squeak/eToys developers hear it often enough, so, again, thanks for this remarkable piece of software. --Randy

Re: [Squeakland] Copying from one project to another?
by Mark Engelberg 25 Oct '05

Sounds like there's lots of good options, but I'm particularly curious to know more about the last option, because it makes me realize that I don't have a complete mental model of how projects "link" to one another, or are loaded when one is already resident in memory. Okay, let's say I'm working in a project (we'll call it Project A), and I realize that I want to get a copy of a car that I used in another project (we'll call it Project B). So naturally, I did a find project, and called up Project B. But then I was inside of Project B, trying to look for a way to get the object out of Project B and into Project A. Eventually, I clicked on "Prev Project" and found myself back in Project A. Interestingly, I discovered a little window depicting Project B in the upper-left corner of Project A. To me, this indicated that Project B had in some sense been loaded "inside of" Project A, rather than as a completely separate entity. If I were to save Project A at this point, would Project B be saved as well, or would it only save a "link" from Project A to Project B? Anyway, next I tried to try drag the car out of the little image of Project B, into Project A, but none of the objects were clickable. So, it sounds like you're saying that there's no way to drag something "out" of a link between projects (without using an intermediary like buffer or supplies), but you CAN drop something into a link. If that's the case, I'm guessing I would have had to do something like this: I'm in Project A, and realize I want something from Project B. I do a "find" to summon up Project B. The I do a "find" to summon up Project A, so that I have a link back to Project A. Then, I drop the object through the link to project A. Then, I go through to project A, and delete the link to Project B, and publish to save. Does that sound right? --Mark Engelberg On 10/25/05, Scott Wallace <scott.wallace(a)squeakland.org> wrote: > Hi, Mark, > > Here are a few options for copying objects from project to project: > > (1) Drag the object into the Supplies bin.

One more question
by Mark Engelberg 21 Oct '05

21 Oct '05

Okay, let's say I'm building a script to draw a square. I drag over a forward and turn tile to an empty script, and set the values accordingly. Now I want to make a copy of those tiles. How do I do this? I tried various ways, but whenever I tried to duplicate a tile, I got a strange error message. --Mark

Slowing down scripts?
by Mark Engelberg 20 Oct '05

20 Oct '05

Is there any way to step through a script, or slow it down? All the actions in a script appear to happen simultaneously. My son would really like to see the car actually draw its "forward 85", then honk, then turn, and so on... --Mark

Getting started
by Mark Engelberg 20 Oct '05

20 Oct '05

I have no previous experience with Smalltalk, but I am an experienced programmer with experience in a large number of programming languages. I discovered Squeakland a few weeks ago, and became convinced that this would be a fun programming activity for my kids. However, I know nothing about Smalltalk, so... I purchased the Powerful Ideas book, and the Bots book. I read everything on Squeakland, and also tried to follow some of the tutorials on the main squeak website. I must admit, there's a lot I'm confused about. Let me list some of my confusions in a stream-of-consciousness way, and maybe you all can jump in with suggestions. 1. Where's the documentation? Maybe it's because Squeak is intended to be an rapidly-evolving language, but the documentation seems very spotty. And that's a shame, because educational value depends a great deal on the quality of documentation. The "Powerful Ideas" book gives detailed steps for completing each of its projects, but it's obvious that this only scratches the surface of what eToys can do. And I can't figure out where to look to find out everything it CAN do. And as the teacher, I really want to know more before I begin. Inevitably, my children will ask in the middle of a project, "But what if I want to ____, how do I do that?" So where is there a more thorough treatment of the full scope of what is possible in eToys? 2. Publishing vs. saving. The first excursion in "Powerful Ideas" talks about publishing one's project. When publishing, the only location Squeak offered for publishing was one called %USERNAME%. What's up with that? It asks whether I want to include all changes? Do I? If I don't include all changes, what is being included? After making some changes, it seems reasonable to want to "publish" it again to make sure a copy is saved. Do I publish with the same name/info, or do I need to give it a new name? If I do publish with the same name, is it possible to recover the previous edition? I also noticed that buried deep within the world menu (which isn't readily accessible in the plug-in), there is a way to "save" or "save and then quit". How does this differ from publishing? Which is the recommended procedure? 3. Etoys vs. Bots. How do others perceive the way that these two environments mesh with one another? It seems to me that Etoys is accessible to pre-typers because of its drag-and-drop style of programming, while Bots goes more in depth into programming concepts. Am I interpreting these two curricula correctly? Is the recommended path to use Etoys followed by Bots? 4. Tweak vs. Squeak. Which one should I be using? 5. After the car curriculum, then what? Is anyone actively developing other Etoys project ideas? 6. Ball dropping movie. I don't have any mechanism for capturing digital video of this. Any chance someone can post the movie used in the book to the website, so we can do the associated project? 7. And what about Alice? I've heard this mentioned as yet another environment within Squeak. How does this fit into the spectrum of Etoys, Bots, and straight squeak programming? Thanks so much, Mark Engelberg

strange behavior - publishing proj w/ siblings
by Randy Heiland 20 Oct '05

20 Oct '05

Hi gang, I've got a strange situation - which is actually kind of time-crucial since it's part of a contribution I'm making to the upcoming Supercomputing 2005 Education Program. In the little module that I'm contributing, I'm introducing Squeak to some of the teachers participating in the Program and, well, I've got a problem with a project involving siblings. Basically, the problem involves scripts getting changed whenever I 'publish' the project. I've quickly documented the situation and made the project available (in its quirky state, after being published) here: http://poincare.uits.iupui.edu/~heiland/squeak/darts/ If one of you Squeak gurus could take a look sometime and offer advice, I'd appreciate it! --Randy
