[Etoys] remedy for lingering cursors and halos
by Scott Wallace 14 Nov '06

14 Nov '06

Hi, all, Hopefully recent etoys/olpc 2.0 updates have reduced the incidence of unwanted halos and cursors hanging around on the screen after a playback of an event-recorded sequence. But in case you encounter such artifacts, they can be annoyingly difficult to get rid of, so it's useful to know that when you do a "restore display" (found in the world menu,) or, equivalently, type cmd-r when the desktop has keyboard focus, all halos and all cursors associated with "replay hands" are eliminated. Cheers, -- Scott

[Etoys] progress in event-recording framework
by Scott Wallace 13 Nov '06

13 Nov '06

Hi, Alan, and all, Lots of progress to report on the event-recording framework in etoys/ olpc2.0; here are some highlights: (1) Voiceover can now be added to an existing recording. Hit the "Record Voiceover" button; the event sequence will be played back (minus any existing sound) and the recorder will record and attach your new audio content. (As before, to record voice at the same time that you make the original event recording, set the "record voice" checkbox in the Options menu before recording.) (2) When you hit the "Publish", you're now offered three kinds of playback-triggering buttons. In addition to the purely "button-like" thumbnail of the past, you can now obtain buttons that appear as scaled-down pictures of the recording. In the "Hint" variant, a 0.3 reduction of the initial scene is presented, overlaid with the word "HINT". A click on one of these brings up, and automatically *plays* and then *dismisses*, the recorded sequence represented; at the end of playback, the playback-space shrinks back down to a 0.5 reduction of the *final* scene in the recording, all as per your suggestions for tutorial scenarios on 28 October. (3) The various playback-inducing buttons now all allow you (via their red-halo menus) to specify whether or not you want auto-start and/or auto-dismiss of the playback. (4) I finally solved the graphics-property-sheet-placement problem. It should now be possible to construct tutorials featuring use of property sheets, with much greater confidence that the property- sheets will appear in the same relative position on the replay. (5) If you try to dismiss an event-recording-framework which has been recorded but never published, you're now warned and given a chance to change your mind. (6) From a playback-inducing button, you can now "re-open" a full recording framework. This allows re-recording of the sound track even if the original event-recording framework is gone. Cheers, -- Scott PS -- two small notes: (a) Sound recording within all variants of the EventRecorder is still broken on the Mac, pending VM fixes. If you use a sufficiently old Mac VM, (i.e. before 3.8.6b4), voice recording on a Mac will work okay, but I'm not certain what other things might be adversely affected by using an old VM. In any case, these issues afaik "only" affect use on the Mac. (b) "Old" event-framework recordings [i.e. those created before this week's improvements] cannot have after-the-fact voiceover added -- sorry, but the hooks are lacking.

[Etoys] Welcome project fills up trash
by Bert Freudenberg 12 Nov '06

Hi Alan, when letting your Welcome project run for a while, in each iteration a new copy of the painted car is added to the trash. If someone would let run this for a longer period, which is not unreasonable for demo purposes, we might run out of memory ... - Bert -

[Etoys] Build 168
by Yoshiki Ohshima 12 Nov '06

12 Nov '06

As of now, the latest disk image available online is "build 168". To have X server start, I need to replace a config file from older version (which is understandable as they seem to be preparing for the deployment with actual display). And, the boot precess fails sometimes (such as saying "Resetting OLPC Wireless" and hang). But if it boots up, eToys runs as expected. eToys doesn't interfere other apps sound playback (but other appls interfere eToys sound playback.) As long as they work out the low-level stuff right, the eToys part is are fine. -- Yoshiki They changed the artwork of buttons in TamTam from grayscale to full-color. Nobody seems to be interested in "freezing" and stabilize software...

[Etoys] Sound Recording on Mac
by Yoshiki Ohshima 09 Nov '06

09 Nov '06

Hello, Has anybody tried sound recording and playback on Mac lately? Scott reported that it is broken in Squeak 3.9 7067 (and OLPC etoys image) on 3.8.12beta4U.app VM. What happens is that if you record your voice with a SoundRecorderMorph or EventRecorderMorph (with the voiceControl enabled) and play the recorded sound back, you get incorrect sound. Here is what Scott described: -------------------------------------- (a) The sound-in-event-recorder bug *does* occur [in 3.9 7067]. But it's slightly different: although the speed of playback is nearly doubled, as in OLPC, the *pitch* does not change. So it is not a Donald Duck sound. (b) Also, the same bug now (i.e. in 3.9) also occurs in the vanilla SoundRecorderMorph! (In the OLPC/Mac image, the vanilla SoundRecorderMorph produces good playback on the Mac -- it's only the use of sound within an EventRecorderMorph that's problematical. In the 3.9/Mac image *every* SoundRecorderMorph use has this problem. But again, the overly-fast playback occurs *without* a pitch rise.) So evidently 3.9 went "final" with the SoundRecorder completely broken on the Mac. -------------------------------------- Can anybody confirm this? Since the same code works on Windows (and presumably on Linux), we kind of suspected a bug in the Mac VM causes the 'stereo' value or sampling rate set incorrectly... Does anybody has an idea? -- Yoshiki

[Etoys] updates
by Yoshiki Ohshima 09 Nov '06

09 Nov '06

We were re-prioritizing the items to work on in coming a few months for the "B-Test2 machine". Most of the team members are working on rather large chunk of task in my previous "Next Steps" email and follow-ups, so we haven't pushed so much changes, but are making some progress. In the mean time, I published a change that addresses the BookMorph issues reporte by Milan. ... As some of you may be aware of, I'm looking at the Craig's authors list (http://www.netjam.org/squeak/contributors/) and figuring out who are these unidentified guys. During this displacement activity, I came across this update for 2.8 alpha: --------------- 2096BooklikeMorph-bf -- Bert Freudenberg & Karl Ramberg -- 7 May 2000 Karl: Makes the Page Controls in BookMorphs pick up a mouseMove so the BookMorph is easier to move around! Bert: Yep, that's nice! But why is it slower than grabbing the book itself? Oh, you're handling #mouseStillDown instead of #mouseDown ... I'll attach a fixed changeset." --------------- Apparently, I just did something these guys did 6 and half years ago^^; As usual, any comments and suggestions are welcome. Thank you! -- Yoshiki

[Etoys] Squeak OLPC2.0 image and update stream
by Scott Wallace 07 Nov '06

07 Nov '06

Hi, all, The version of etoys/squeak for the olpc that we have been developing these past few months is called "OLPC1.0". That version will continue to embody the official image for the etoys submission to the b1 build. Although this is now essentially frozen, critical bugs may continue to be fixed as time permits, so people will want to keep, and continue to load updates into, their OLPC1.0 Squeak images. For our ongoing work, looking forward toward b2 and beyond, we've now established a separate image and attendant update stream, called "OLPC2.0". You can get a 2.0 image either by evolving a copy of an existing 1.0 image or by loading a fresh 2.0 image from a server. (1) Evolve any up-to-date OLPC1.0 image (update level 1102 or greater) into an OLPC2.0 image by installing the attached fileout, then loading updates, then saving the image. A copy of this fileout can also be downloaded from: http://tinlizzie.org/olpc/jumpToTwoPointOh-sw.cs.gz (2) Alternatively, there are pre-built OLPC2.0 images available for both the plug-in and the development versions on the tinlizzie server. You can find them here: http://tinlizzie.org/olpc/OLPCPlugin-1111.zip -- plug-in version of OLPC2.0 image http://tinlizzie.org/olpc/OLPC-Squeak-1111.zip -- development version of OLPC2.0 image Cheers, -- Scott NOTE: On the same tinlizzie server (http://tinlizzie.org/olpc/) can also be found up-to-date copies of OLPC1.0 images, which are currently at update level 1108: http://tinlizzie.org/olpc/OLPCPlugin-1108.zip -- plug-in version of OLPC1.0 image http://tinlizzie.org/olpc/OLPC-Squeak-1108.zip -- development version of OLPC1.0 image

[Etoys] Camera (was Re: [Trac #175] Squeak/Etoys needs packaging)

Well, there is "VideoFlow", which looks interesting, but requires a plugin that might not have been ported to Linux yet: http://minnow.cc.gatech.edu/squeak/2411 And I just received some old bits from Tim Rowledge which once formed a Video4Linux plugin. How would I access the camera? And until I get a b-test, could this be simulated by a USB camera? - Bert -
