[sugar] Activity updates in joyride (was Re: TurtleArt-18)
Actually, there currently is *no way* to update the wiki with the latest version of any G1G1 activity *without* affecting the pegged version. I repeatedly pinged the OLPC list but everyone seems to busy to fix the wiki (and some of the relevant pages pages are locked). The page that 8.2 laptops are updating from is http://wiki.laptop.org/go/Activities/G1G1/8.2 As you can see this incorrectly points to the *latest* version of each activity in the G1G1 set. It should point to the *8.2* version of each activity.

I did update the link in w.l.o/go/Activities/All but I actually was hoping for some testing on this rather major intervention before it became the defacto version for G1G1.2.

Sorry about the type re 16, 18. The source is http://dev.laptop.org/pub/sugar/sources/TurtleArt/TurtleArt-18.tar.bz2 Regarding the PO files, I actually sent Sayamindu a PO file for a Turtle Art entry in Pootle last night (attached here) along with translations for Spanish, French, Turkish, Mongolian, and Finnish.

If you have any interest in this, I'd be willing to take a shot at hand-editing a PO file that could server this purpose.

Hi, I mistakenly CC'ed rather than BCC'ing in an earlier message in this thread. If you'd kindly edit out the @gallaudet.edu addresses, I'd appreciate it, as none of the folks on that list are at all technical, and wouldn't know Sugar from Salt. ;-) And the likelihood of them signing up for a mailing list, spending time on a wiki or cranking up IRC is next to nil. (I CC'ed them specifically to show that there was, once again, some interest in this technology for deaf students, as they have periodically hinted that they might try to get something going in deaf schools in Costa Rica.)

Sayamindu Dasgupta wrote: On Sun, Nov 23, 2008 at 10:44 PM, Daniel Drake [EMAIL PROTECTED] wrote: Hi, As we all know, latest joyride can't launch activities. Chris Ball pointed out that disabling rainbow solves the issue. The problem is that the sugar module imports try to read the XO nickname, colours, etc, information which is now stored in gconf. But, gconf is a per-user thing, everyone has their own store. Rainbow launches activities as different users, so with the default behaviour we cannot expect activities to be able to access sugar's configuration. Potential workaround: set ORBIT_SOCKETDIR=/tmp/orbit-olpc in rainbow, and loosen permissions on /tmp/orbit-olpc/* This works, but causes gconf to complain loudly that /tmp/orbit-olpc is not owned by the current user (i.e. the one running the activity) Tomeu raised the point that GConf2-dbus would solve this, as it provides a per-session-bus settings repository, rather than a per-user one. Rainbow already shares the session bus between olpc user and activities. We actually shipped GConf2-dbus in 8.1, but dropped it for 8.2 because at the time, nobody could offer an explanation of why we might need or want it. Switching back to GConf2-dbus does raise some questions though: - It looks like a dead project. Not updated since 2.16.0. Do we want to be burdened with it? miraculously, it compiles and works fine after a BuildRequires tweak: http://koji.fedoraproject.org/koji/taskinfo?taskID=946380 - This still raises questions about our security model, IMO. Rainbow prevents activities from messing with 'the rest of the system.' But if we let activities access gconf, they can screw up any application that stores information there (e.g. sugar). - and the above point raises the possibility of a per-activity gconf store, with associated gconf daemon, but this adds about 2mb memory usage per activity... IIRC, the reason we wanted Gconf Dbus was that we wanted to avoid the dependency on Orbit and the rest of the stuff that it pulls in. Is there any reason to do otherwise at the moment ? I think upstream GNOMe has also plans to switch to GConf Dbus[1], but I'm not sure when. The maemo guys seem to be using GConf Dbus as well. Thanks, Sayamindu [1] http://projects.gnome.org/gconf/plans.html We use gconf-dbus as well in sugar-jhbuild to be able to run several instances (SUGAR_PROFILE=sayamindu2 sugar-emulator) Best, Simon ___ Sugar mailing list Sugar@lists.laptop.org http://lists.laptop.org/listinfo/sugar

[sugar] Finding cursors. Ripples in a puddle?
Does anyone else recall recurring debates about cursor size and the effect on one's ability to visually discover the location of a cursor? Yes, there are tradeoffs between simply making cursors larger (easier to discover location) or making cursors smaller (easier to place precisely, eclipses fewer pixels)...especially when the pointing devices are other than by directly touching the display screen. Such is the case with the present XO laptops. To sidestep those debates, I imagine a different way -- one in which cursors could be of any size, color, shape, etc. -- and yet still draw my eye quickly to the locus of the current cursor. VISION: Each time my finger tip lands on the touch pad I see a circular wavefront (on the display, of course) briefly emanating from the point of the cursor. The wave gently fades as it grows and dissipates. Thus, it appears as if the screen is overlaid with a clear puddle and I have lightly touched its surface. The effect could be simulated with a simple ring; probably a simpler and cheaper computation than a wave effect. A bitblt series would do. Like ripples in a puddle, the visual effect and conceptual metaphor would seem to draw on nearly universal human experience from early childhood. Of course, the HCI labs around the world could experiment with such effects (if not already) to understand the human factors and optimize the man-machine interface. Meanwhile, it seems worth trying, pragmatically. ;-) Cheers, -Ken Ritchie (Atlanta) ___ Sugar mailing list Sugar@lists.laptop.org http://lists.laptop.org/listinfo/sugar
