New activity: Speak
Hi everyone, I made a new activity called Speak. It is a talking face for the XO laptop. Anything you type will be spoken aloud using the XO's speech synthesizer, espeak. You can adjust the accent, rate and pitch of the voice as well as the shape of the eyes and mouth. This is a great way to experiment with the speech synthesizer, learn to type or just have fun making a funny face for your XO. I hope you like it. http://wiki.laptop.org/go/Speak Thanks to Arjun Sarwal, Hemant Goyal and Bernardo Innocenti for their advice while making this. Also, if anyone has experience or ideas on how to get access to espeak's per-phoneme timing data from python, please let me know. -josh ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Joyride as alternate boot
What's the recommended best practice for alternating between stable and unstable builds (Update.1 and Joyride)? We can have two builds installed at the same time, and the O game key toggles between both. But how do I tell olpc-update to update the other build? I can boot into Joyride, and update to Update.1, which makes Joyride the alternative boot, right? But this would not actually patch the Update.1 to the new Update.1, but the old Joyride to Update.1. Not sure I'm making myself clear, but essentially I want a cheap way (i.e. minimizing network traffic) to toggle between two build streams, updating each one separately ... - Bert - ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

auto screen rotation
I just installed 679 and one new feature is that switching to tablet mode rotates the screen to one click from normal and lifting the screen rotates to normal. these positions are absolute, no matter hat the user selects. this means that when I switch to tablut mode and put the screen back in landscape mode I'm left with the mouse pointer in the middle of the screen, I lift thescreen enough to reach the mousepad and flick the mouse to the right edge, then lose the screen and it rotates on me (and when I totate it three more clicks to get it back the mouse is back in the middle of the text I am trying to read) twwo thing here 1.why is it going to portrit mode? I can see some justaficaton for either landscape mode (depending on if you want the direction gamepad under your left or roght thumb and the extra space for the handle to the top or bottom) but I don't see any nice way to use both of the gamepad controls in portrit mode. (I do use portrit mode sometimes to make reading tall, narrow ccolumns easier, but it's hardly my default) 2. this is overriding what the user is explicitly setting, why, and how can a user change this default?

Oh, and to answer your questions: do the lid close switches show up to the system as keypresses? Sort of, yes; they show up on their own Linux input device. To see all of the input devices hooked up this way, you can: cat /proc/bus/input/devices However, HAL claims ownership of the ebook switch devic; the correct way to query it is to ask HAL. To get the current value of the ebook sensor, you can run lshal and look at the button.state_value value in the OLPC ebook switch section. To monitor the value in real-time, you would watch the messages coming out of HAL's dbus interface.

Controlling the Glide/Pressure sensor
I have a student who's interested in doing a term project on the UI for the track sensor. I've put together this quick summary. Deadline looms for starting the project, so if people have don't do that or we've already done that feedback, please speak up ASAP. Background: * XO has two different devices, resistive glide-sensor and pressure-sensitive tablet o Both of these are currently showing up as core pointer events in X AFAIK o Changes between pressure and glide-sensor activity have the potential to cause jumps of the cursor (absolute versus relative mode) * There is currently no UI to map the pressure-sensitive tablet's area into a particular area on the screen (nor, AFAIK an API to accomplish the mapping) o Use case: use the entire drawing area to draw into a small area of a drawing in Paint * Activities currently do not have control over the mapping of the area o Use case: in a penmanship course, collect samples of the child's letters in special widget areas within a test, focusing a new area should remap the pen to that area Trackpad UI Design Requirements: * API for configuring the resistive/pressure sensor allowing control of all the major features o Note that there will likely be some X11 hacking here, to get the pointer mapping working * Standard UI controls for redirecting input areas o Standard GTK UI for positioning, and scaling o Standard GTK widget for e.g. handwritten text entry, provide access as a bitmap (or a series of strokes optional) + Allow for capturing all data (full resolution) or just scaled data as configuration option o Intuitive (HIG-compliant) standard mechanisms for controlling the various configuration parameters o A 6 year old should be able to figure out how to direct their drawings, written text and the like into the desired areas o Standard feedback on where the tablet area is bounded on screen when drawing with the tablet * System level (possibly on Sugar's Frame) trigger to bring up the control mechanisms (optional) o Most pen-aware applications will likely use internal logic and the API to determine position and the like, but a general trigger to the functionality should be useful for non-pen-aware activities * Paint Controls o Work with Paint's authors to provide intuitive controls to make using the pen/tablet intuitive within the context of paint Obviously we would need to find a machine to work on to make the project feasible. I'll see if we can repurpose one that's local to the task. Discussions welcome, Mike -- Mike C.

Is there a dial widget in Sugar? I don't think GTK offers one (I never found it), although writing one in C seems easy (but how to include in the XO builds?). In addition, is there a reference for GUI components in Sugar, above and beyond the ones provided by GTK?

Re: Controlling the Glide/Pressure sensor
We put a lot of thought into how this might work for the Paint activity in particular, which seems like it would be a prime example for it's use in an arbitrarily large space. Special care was taken to minimize the extent to which one would have to switch between stylus and finger while drawing. Naturally, designs for activities like chat, or handwriting, etc. may not depend on the ability to adjust the location of the mapped input region on screen. http://wiki.laptop.org/go/Draw#Tablet_Support - Eben On Jan 10, 2008 11:04 AM, Bert Freudenberg [EMAIL PROTECTED] wrote: On Jan 10, 2008, at 16:46 , Mike C.

Re: New activity: Speak
Hi Josh - This is pretty fantastic. I've enjoyed playing around with it. One simple change that I think would add a lot is some color. More specifically, the XO uses a two-tone (stroke fill) color scheme as a form of visual identity. It would be great to fill the entire background in the child's chosen fill color, and perhaps render the mouth in the stroke color, to emphasize the identity of each child's XO. There is an API for obtaining these colors. Another nice touch would be to make the eyes follow the carat while typing, instead of remaining focused on the mouse (since, one would assume, use of mouse and keyboard are mutually exclusive), as though he were anticipating what he was about to say. Finally, a subtle but wonderfully effective technique that a professor of mine often used for characters with eyes is to periodically return the pupils to the center of the eyeball. This creates a sort of dialogue between the character and the child, as it appears that the he is interested both in the movement of the cursor and in the individual moving it. - Eben On Jan 10, 2008 4:27 AM, Joshua Minor [EMAIL PROTECTED] wrote: Hi everyone, I made a new activity called Speak.

Re: mesh portal discovery
IP addresses are going to change; that's a fact of life. I know nothing about routing, but if a participant's IP address is about to change, perhaps the change should be broadcast over the network, so that Telepathy knows who to handoff the connection to. To re-ground this discussion, if two mesh portals appear on the network, at different IP addresses, a laptop can continue to use the old one for its existing connections, yet switch its primary address to a new (better) one for new connections. IPv6 includes host-based tools for making IP address changes easier. In particular, it requires the kernel to be able to process several global IP addresses for a given hardware interface. The latest is marked preferred, the rest are marked deprecated. When creating new connections, it normally uses the preferred address. But communication over all of the addresses continues to work (as long as the network outside the kernel has connectivity at that address). Linux implements all of this for IPv6. I don't know if the Linux kernel can do the same for IPv4, but it would be a natural extension. Some applications care what IP address they are using; bind (DNS) in particular watches for interfaces to go up or down, or to change.

Update.1 680 does not work for me
Downloaded build 680 two hours ago. Installed it (together with ROM Q2D08) on my G1G1, going by the directions on the wiki Autoreinstallation page. On boot, the Home screen comes up __without__ the Journal. None of the Activities will start (presumably because they need the Journal).

Another nice touch would be to make the eyes follow the carat while typing, instead of remaining focused on the mouse Two great ideas. Adding color will be super easy. I can make a toggle between black/white and the user's colors. Is there a kid- friendly sugar or gtk color picker, like the box-of-crayons one on the Mac? That would let them play with the colors too. I'll see if I can get access to the carat location easily. Finally, a subtle but wonderfully effective technique that a professor of mine often used for characters with eyes is to periodically return the pupils to the center of the eyeball. This creates a sort of dialogue between the character and the child, as it appears that the he is interested both in the movement of the cursor and in the individual moving it. Neat!

Re: mesh portal discovery
On Thu, 10 Jan 2008, John Gilmore wrote: IP addresses are going to change; that's a fact of life. I know nothing about routing, but if a participant's IP address is about to change, perhaps the change should be broadcast over the network, so that Telepathy knows who to handoff the connection to. To re-ground this discussion, if two mesh portals appear on the network, at different IP addresses, a laptop can continue to use the old one for its existing connections, yet switch its primary address to a new (better) one for new connections. why is it that the laptop needs to switch IP addresses? is it that the new portal won't talk to the old IP address? or is it that outbound traffic could go out either portal, but inbound traffic would still go to the old portal and make more hops over the radio then is nessasary? or something else? IPv6 includes host-based tools for making IP address changes easier. In particular, it requires the kernel to be able to process several global IP addresses for a given hardware interface. The latest is marked preferred, the rest are marked deprecated. When creating new connections, it normally uses the preferred address. But communication over all of the addresses continues to work (as long as the network outside the kernel has connectivity at that address). Linux implements all of this for IPv6. I don't know if the Linux kernel can do the same for IPv4, but it would be a natural extension. Some applications care what IP address they are using; bind (DNS) in particular watches for interfaces to go up or down, or to change. If Telepathy wants to do the same, yet there is no low-overhead way to do it, then another natural extension would be to extend inotify (or raw sockets, or some other kernel mechanism) to report such changes. This would avoid polling for them. but is it really the right thing to try and do this on the laptops (in the OS and all the software), or should we do it in the portal boxes instead? As long as the previous mesh portal continues to work for a short while, there should be no need for nonstandard mechanisms to let applications know that the IP address is *about* to change. Instead they will naturally find out after it *does* change. this gets back to my question about exactly why the change is a problem.

Marvell microkernel replacement
I see on http://dev.laptop.org/ticket/46 that there is a plan for replacing the proprietary microkernel in the Marvell wireless firmware with something Free so that, as I understand it, the OLPC XO can be the first computer to be delivered running only Free Software. In private conversation with Richard Stallman, he told me that this is the only obstacle to him supporting the project fully. I see rather sporadic activity on the bug, but Walter has just said that we can reopen this with Marvell in bug 429.

Re: [sugar] New activity: Speak
Since you're writing out the wave file, it would be nice to be able to convert existing online material to stored waves that can be retrieved at a later date to provide podcast like capability for listening while performing some other duty that would not allow you to be hands on. Perhaps a way to paste in content and store rather than have the final result be short-lived.

Do you support this? Speak calls the espeak command line tool to query the available languages as well as to generate the audio, so any new or changed voices in espeak will show up in Speak automatically. It does filter out the Mbrola voices because they don't actually produce sound. I plan to experiment with calling espeak via their API but I will make sure to avoid any limitation on the set of languages. Can this or the Screen Reader project be adapted to reading content, such as the children's picturebooks provided in the Library? (We would presumably need a text file to go with each document.) I think that it would be a great boost for child and adult literacy both if little children could sit on their parents' or grandparents laps and have the XO read them both a story. XO is the new Teddy Ruxpin :) I was thinking of adding a toolbar tab to allow for some sort of game/ story/lesson modes. It would be cool if someone could write a plugin/ extension for a guessing game, story reader, spelling game (ala TalknType) or something like that. I have also considered wrapping Speak into a reusable component so other activities could add a talking face easily. I'm not sure of the best way to do this. In that same vein, would anybody be interested in creating a karaoke activity? Same-language captioning of Bollywood musicals is claimed to be the most effective literacy measure in India. That would be awesome! Also, if anyone has experience or ideas on how to get access to espeak's per-phoneme timing data from python, please let me know. -josh Do you want to do that while running, or would a precomputed table meet your needs? I would like to get callbacks for each phoneme while the voice is playing, so that I can shape the mouth correctly for each one. If done well, this could be a nice visual cue to help understand the voice. I would also have to rework how espeak is wired up to gstreamer. Right now I have espeak write out a wav file and then I play that back via the gst module. I wasn't able to get them piped together in a reliable way. Specifically when I run espeak --stdout and then attach that to a gst pipeline that starts with an fdsrc, it only works once. I was not able to restart or rebuild a new pipeline to speak another sentence. -josh ___ Sugar mailing list [EMAIL PROTECTED] http://lists.laptop.org/listinfo/sugar ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
[OLPC devel] su/sudo or not to sudo/su (was PATCH: add --loginpause to mingetty)
Bernardo, FYI, I just recently updated from build 650 (G1G1 factory build) to Update.1675. Noticed a different behavior for accessing *root account* and functions. I used to be able to open Terminal (or Ctrl-Alt-Neighborhood) and the following at the unix/bash prompt. $ su - or $ su -l But now, after the update, those don't seem to work. But I did discover the alternative method.. $ sudo command I typically like the solution of $ sudo bash for several root level commands. QUESTION: Which direction is OLPC/XO Laptop headed for doing updates and installation of software ? One could also, limit the programs which can be run under 'sudo', as another solution.
