Re: [IAEP] New and revised chapters of "Make Your Own Sugar Activities!" ready for review, feedback
Sean, I appreciate the support, but I don't think what I have written is going to be anything like a finished product by February 3. A homepage link to the OLPC content on Floss Manuals might be appropriate, since there are some finished manuals there and the book might appear on that page in a couple of months. I wanted to add a chapter on Collaboration and another on Debugging before I considered it front-page-worthy. As for press releases and the like I don't know that one guy writing a manual in his spare time is going to impress anyone. A finished book (and I think the book needs more than the two chapters I mentioned to be considered finished) or a whole team of people working on a book would be a different story. Making more Activities available, and especially convincing teachers and children to try and write Activities is definitely my goal, and I hope that when we have a more finished product that as many people as possible get to know about it.

Re: [IAEP] New and revised chapters of "Make Your Own Sugar Activities!" ready for review, feedback
I consider this to be a fabulous initiative. Growing the Activity ecosystem is very important for Sugar and OLPC and a handbook has been a missing link. I will speak with Christian about a homepage link and I even think we should do a callout in our next press release, tentatively scheduled for February 3, the day OLPC France will present the OLPC project (and myself Sugar) to France's largest corporate foundations at L'Atelier (http://www.atelier.fr/usages/3/07012010/one-laptop-per-child-ordinateur-veritable-revolution-pedagogique-39192-.html) Thanks.

Re: [IAEP] New and revised chapters of "Make Your Own Sugar Activities!" ready for review, feedback
Aleksey, I tried out your new speech.py last night and it checked out OK. I've put this code in the book and in Git. I will probably add an example of how to use espeak word splitting before the book is published. Right now I need to work on learning collaboration so I can teach it to others, but I'll come back to this chapter soon. I don't know if I'm going to mention GroupThink in this book or not. I want to create some simple collaboration examples, explain them, then see how I feel about adding more content. GroupThink doesn't look like something for a beginner's book. Maybe when this book is out the door some more qualified person will do an advanced book covering all the stuff I could not.

Re: [IAEP] New and revised chapters of "Make Your Own Sugar Activities!" ready for review, feedback
Aleksey, I did consider mentioning the word tracking feature you put in your example. However, when I tried your example with actual book text rather than letting it speak the source code of the program it seemed to actually skip speaking some of the words. The markup version was more robust. The machine I used for that test was running Fedora 10, and it may be that in 11 or 12 it would work better. I have another box running 11 and I could try it there. I do have your examples in the Git project for the book so readers could discover them on their own. I could see word tracking being useful in the core Read Activity. Actually highlighting text in place in PDF documents and scanned page images is not as simple as what I'm doing with plain text, but perhaps in Read you could have the spoken words appear in a text crawl at the top of the screen. Right now I want to work on collaboration examples but I may revisit this chapter and add something on word tracking.

Re: [IAEP] New and revised chapters of "Make Your Own Sugar Activities!" ready for review, feedback
Aleksey, Thanks for your feedback. I'll check out your new code when I get home. Offhand I can't tell what you changed, but I'll make sure to test everything before I update the chapter. I was hoping that speech.py could be a file that new developers could drop into their Activities without fully understanding it. Your work has made speech easy to add to an Activity, so maybe after the book is out we'll start seeing more Activities that use it.

and also, could be useful to mention words tracking feature of espeak,
like
http://wiki.sugarlabs.org/go/Activity_Team/gst-plugins-espeak#Simple_TTS_example
Yes, some espeak versions(at least old ones) could miss some words but
its getting better(I didn't check last espeak version but at least
espeak developers are working on track improvements) and in case of
simple tts usage, just reusing espeak native feature would be more
useful than coding marking stuff.

[IAEP] New and revised chapters of "Make Your Own Sugar Activities!" ready for review, feedback
I just finished writing another chapter of the book, this one on adding Text to Speech to your Activities. I've also made various additions and corrections to the rest of it. If you want to check out what I have a PDF created with OBJAVI! is available here: http://objavi.flossmanuals.net/books/ActivitiesGuideSugar-en-2010.01.21-18.33.56.pdf I'm going to start working on code samples for a Collaboration chapter next, and I want to do a chapter on debugging Sugar Activities after that. I think Walter had developed some code to let you run Sugar Activities outside of the Sugar environment and that would be a good fit for the debugging chapter. For collaboration I'm going to try to put together a sort of half-finished game called "Battle Royale Tic Tac Toe". I'll also write about file sharing as used by Read Etexts. Once I have this material added I think I'll have enough to make it worth putting on the front page of the site. That won't mean it's finished, but enough of it will be that the book could be considered complete. I welcome collaborators as well as editors on this. There are many topics you could put in a book like this that I'm not qualified to write. I'm up to 87 pages now. James Simmons ___ IAEP -- It's An Education Project (not a laptop project!)
