[Etoys] New tiles for sound volume
by Tetsuya HAYASHI 18 Jan '07

18 Jan '07

Hi, all, I add some new tiles for sound volume, 'loudness', 'balance', 'left volume', and 'right volume'. Each morph has its own these values, and it would provide pseudo stereo sound effect. This changeset is here, http://magicbasket.jp/Etoys/uploads/3/SoundVolumeEnh-tetha.cs.gz and the exapmle project is the below link (it includes changeset already, so you can taste it quickly without 'file in', download and load only this one). http://magicbasket.jp/Etoys/uploads/3/SoundVolumeEx.pr.gz I would like to know how it works on the OLPC machine. Any sugestions or advices would be much appreciated. Have fun, -- Tetsuya HAYASHI, tetha(a)mac.com, tetha(a)st.rim.or.jp

[Etoys] Examples need to be updated
by Yoshiki Ohshima 17 Jan '07

17 Jan '07

Hello, This week, another software "freeze" for B2 machine is supposed to happen. Thanks to everybody contributed and gave moral support, Etoys part is basically in pretty good shape. The developers' practice we learned from B1 machine is that they reflash the entire disk image very often, as there is no official system update mechanism for OLPC yet. This means that the software "deadline" isn't really a "dead" line. Everyday, people reflash the disk image with whatever we would like to put. A difference of B2 machine is that it will be produced in bigger quantity, and some of them are going to non-developers. These non-developers wouldn't update the disk image, but they shouldn't care the detail so much either, hopefully. If our Etoys is functioning as much as it is doing now, these non-developers users will be fine, too. Anyway, again, we are basically in good shape. However, we need to update the examples. Because we change fonts, all projects we would like to carry forward to B2 from B1 should be revisited and updated. To help this process, I published a change set that automatically updates scriptors and watchers. However, there are some need for human intervention; the scriptors will become bigger so they may overlap, buttons or other widgets such as RecordingControlMorph won't get updated, etc., etc. Also, it would be nice to have some more examples for Diego's Video stuff, WorldStethoscope and new sound features, times repeat, and Scott's event roll, etc. If you have any suggestions, please send us project files. Thank you! -- Yoshiki

(¿It's > this the proper place?) My wife and I have quite and extensive collection of fairy tales, folklore, and similar from different countries and cultures, and this is an intriguing idea to me. I will have to take a look at his work and see what I could come up with... I have been trying to learn Smalltalk (although I am not too far along yet...) so this could be a good project.

[Etoys] Update on OLPC Etoys
by Yoshiki Ohshima 11 Jan '07

11 Jan '07

Hello, We haven't reporting our progress so much to general OLPC dev community, but of course the Etoys team has been good progress since the B1 release. A few highlights are: * Video interface. You can manipulate, rotate, move and etc. the movie stream (taking a still frame is something a kid can program in visual programming interface). * World Stethoscope. There is a little piece of hardware that converts input from various sensors into sound frequency. You can plug that to B1 machine, and use the input as the program element in Etoys. (Or, any simple microphone works, too, if the input is sound.) * Various improvements including the visual appearance such as fonts. There are still some items on the trac, but these are actually solved by yesterday. Early tomorrow, Bert in Germany wiil make up RPM files to be included to the build images. (Then, I'll close these items on trac.) -- Yoshiki

[Etoys] BookMorph buttons
by karl 09 Jan '07

09 Jan '07

The BookMorph buttons got a little better with the color fix that got added, but I think the buttons should conform more to the other buttons in the image. The book menu button being a dot is just a example of how it should not be. Karl

[Etoys] Navigator flap undo button font fix

07 Jan '07

This fixes a issue with the navigator undo button font. You have to reinstall the flaps for change to take effect.

The file dialog you get when you try to open a MPEG file is not using the fontsize changes. Karl

[Etoys] Attempt to interactive geometry in SqueakLand-OLPC
by Hilaire Fernandes 06 Jan '07

06 Jan '07

Hello all, I have installed and played a bit with my DrGeoII package[1] within SqueakLand-OLPC image. DrGeoII is about interactive geometry within Squeak, it is a major rewrite of an C++/GTK+ application[2]. Loading the specific version 72[3] in SqueakLand-OLPC is no problem. From a workspace, executing "DrGApp new" open a new sketch ready for manipulation. So far the compatibility is quite good. It is not surprising as DrGeoII was written with Squeak3.8. I have tested the Etoys scripting over geometric point of DrGeoII and it works ok. The interface is still in French, but this can be changed easily. However I have noted the accented characters in the DrGeoII messages are not good. I am not sure but I think the characters in DrGeoII are UTF-8, and those characters were inputed from a Squeak3.8 image. I don't understand why it is becoming incompatible. Any idea? Another point I am curious about is how responsive is DrGeoII within a OLPC. On my AMD1000Mhz machine it is very smooth and interactive but it may be different story with the OLPC and Geode CPU (as long as Geode integrates a FPU it should be just fine) If someone with an OLPC unit could load it[3] and report it there I would be very interested.

[Etoys] world stethoscope on B1 machine
by Yoshiki Ohshima 06 Jan '07

06 Jan '07

I tested World Stethoscope on the B1 machine. It works pretty good, given that the hardware is still in beta. It seems that the noise level is somewhat high so tht actual input sometimes doesn't pick up the actual input, but that happens only when, for example, the input to the light sensor is too weak, etc. The viewer's readouts don't update themselves that often (we set #stepTime smaller), but if you use the readout from WS in a script and tick it, it does follow the input with relatively low latency. Just FYI. -- Yoshiki

[Etoys] update 1163
by Yoshiki Ohshima 03 Jan '07

03 Jan '07

Hello and Happy New Year! It is time to get back to work. As a start, I made up new images and uploaded them to the tinlizzie.org server. Among other things, We've decided to experiment with TrueType fonts a bit more. For that purpose, we pre-load Komika font to the image. To be up to date, there are two ways: 1. Download http://pedroreina.net/apostrophiclab/0141-KomikaText/komtext_tt.zip and extract the .ttf files in it to the directory where .image resides. And, then, choose "update code from server". 2. Download: http://tinlizzie.org/olpc/etoys-2.0-1161.zip and/or http://tinlizzie.org/olpc/etoys-dev-2.0-1161.zip and keep code update with "update code from server". Update #1161 is the one that loads the fonts. I thought I made it so that if you don't have the .ttf files in the directory, the update process stops... But it doesn't work in that way. Even if you don't have the font files, the update process keeps going. Please be sure that you will have Komika fonts in your image to fetch further updates. I still haven't gotten to the point where I can integrate the Pango stuff I'm working on. After it happens, hopefully we can dump these fonts in image and use Pango for rendering text. Thank you! -- Yoshiki
