Re: [Sugar-devel] Porting Sugar on Android (Ice cream sandwich)
Yes, Prof. Nagarjunaji, I have heard of your device and was really keen on the opportunity to interact with you over it. Of course, I am not one for reinventing the wheel and hence, the possible steps plus I, too, am more in favor of the 2nd option. Though, interestingly, Peter Robinson's suggestion makes a lot of sense of having a Fedora when, anyway, there is Linux under. I will definitely meet up with you in Mumbai when the opportunity comes forth. though touchscreen may have some advantages for some activities. Second, Sugar learning platform has plenty of activities to offer which are not available on Android currently. 1. Touchscreen opens up a lot of possibilities by way of creating more touchscreen conducive activities that are culture, locale specific. Enabling Touchscreen event for existing activities does not necessarily leverage the advantage of touch screen in enhancing the existing learning experience and to this regard, I am concerned about the complete picture of enabling a hand-held device to the optimum performance and therefore, this question. 2. Second you totally on the second.

Almost all the hardware on A10 chipset is working with the linux kernel without any binary blobs. We work in Mumbai. In case you are around the city, we can meet and discuss how we can work together. The reason why 1 is not considered for us an option is: what children need is not a desktop that is meant mainly for delivery of content to play multimedia files and do business communications. We would like the children to work, do activities using a workspace that can be used with a keyboard, though touchscreen may have some advantages for some activities.

Re: Video (panned fast) goes for a toss
Jon, So, if you use mencoder and encode it with some other video encoder like a wmv or mpeg4 and convert the .ogv file, it should work properly?

The fast panning is causing the video + audio encoding cpu utilization to be greater than the XO 1.75 can schedule. With the current 1.75 codecs the audio capture and encoding takes quite a bit by itself, and after you do a fast pan the theora encoder has to work much harder trying to match the encoded video with the audio trying to keep it in sync.

Re: Renaming the Telescope activity to Scope
Thanks, Gary. I must mention here that the Moon activity is one of my favorites. Having been an astronomy buff, I can understand what the modern sky does to the activity. At times, even Sirius is not visible where I live, where a couple of decades back I and my friends could spot Andromeda or so we believed :)! The polluted sky is probably more assertive here in Delhi ! The above project uses a mounting bracket that attaches the monocular firmly to the XO so it is easier to aim. Thanks for this very useful info, will try it if I can get hold of a monocular here. Thanks, Jv P.S. I have a collection of Moon test images I should really go upload to the wiki soon... Will look out for them!

Have a look at the learning resources pdf at: http://wiki.sugarlabs.org/go/Activities/Moon#Learning_Resources This covers research into a low cost monocular project that Telescope activity was originally aimed at. For Moon observing I have had fair success using a Brunton 10-30x21 monocular. It can be carefully held against the XO bezel over the camera, but that's quite hard work to keep everything still and pointed at the correct location ;) The above project uses a mounting bracket that attaches the monocular firmly to the XO so it is easier to aim. For imaging planets (e.g Jupiter/Saturn with moons) that monocular does not quite get enough light into the camera to show the moons, though I do have a light polluted sky here so you might manage better.

Re: Renaming the Telescope activity to Scope

Furthermore following controls and settings can be set in this mode: * Capture the image * Change camera settings like Exposure, Brightness, Contrast etc. * Delay while capturing the image * Digitally zoom the live image by 1X, 2X, 3X and 4X Please clarify as this looks like an impressive activity and I would like to use it in demos.

I could see Telescope and Microscope as two different activities in the future with different features. For eg, in the Telescope activity you could have: 1. Dark Frame Subtraction 2. High-Gain Noise Suppression 3. Enabling the camera's night-mode. 4. Crosshairs on the screen Right now, none of this exists, and I don't have the bandwidth to develop those features.

Thanks for your patience in response to my quite simple queries. About me, I have worked on Mac OS X about 7-8 years back with Objective C and am familiar with the Unix, BSD and Ubuntu environments but again from some time back.

Cool! Makes sense now. the USB mode switch utility might be used. How? I don't know yet, because I'm waiting to see your response to Jerry where he said Can you plug in your 3G dongle, copy /var/log/messages to a usbkey and post that please, need to see if your card is detected correctly. Please remember I am totally new to how Sugar and GNOME work together. I will catch up but right now, what I need to know is echo '0x16d8 0x6280' /sys/bus/usb-serial/drivers/option1/new_id is it in the Sugar Terminal activity or in GNome ? Let me de-emphasise this. This was just an example for illustration, I don't know yet if this will work for you, as I'm waiting to see your response to Jerry. Taking your question as general, if you were testing this method, it would be better to do it in the Sugar Terminal activity than in the GNOME Terminal application, because you would next use the Sugar Frame to check the result. Having to switch from GNOME to Sugar would be time consuming. However, system commands entered into a shell would be effective from either GNOME Terminal application or the Sugar Terminal activity, or from other methods such as the text virtual console or an SSH session. How Sugar and GNOME work together: Sugar and GNOME are desktop environments http://en.wikipedia.org/wiki/Desktop_environment and both are built on top of Linux operating system and kernel. GNOME also provides a middle level that Sugar uses. On the OLPC XO, you can switch between GNOME and Sugar desktop environments. add the product and vendor identifiers to the new_id sysfs file for the device driver Is the sysfs file the same as sysconfig file ?(in the attached file at the beginning of this mail thread) No, it is not the same. The sysfs is a tree of files beneath the /sys name, and is explained here: http://en.wikipedia.org/wiki/Sysfs In this thread context, sysfs is a method of controlling device drivers, in particular the device driver loaded when you connect the 3G USB modem. On the other hand, the SysConfig file on the USB storage endpoint of your 3G USB modem is a file provided by the manufacturer or wireless service provider.

There are many interfaces between Sugar and GNOME, and they would be costly to explain in detail ... so it depends on the reason for your question. For the configuration and connection of a 3G USB modem, the common software components are NetworkManager and the kernel. Both Sugar and GNOME depend on these. The recognition of USB modems is done by the kernel. Sending commands to initiate a connection is done by NetworkManager. GNOME and Sugar provide connection configuration details to NetworkManager.

Re: SD Card bug? XO 1.75 (Repeat post)
Hi Jerry, Is this a response to my question? If yes, mine is a XO 1.75 C2 and since I am new to Sugar and OLPC, I am not very good at the various versions. What I can tell you is that I have been through the Network Manager but it asks for details (like username, password etc) that are needed when I use the 3G dongle on a Windows box and which are not provided by the provider (India telecom provider - Airtel) I thought of using the wvdial to set it up but do you mean that I can plug in the dongle and it will plug and play? I did not want to try it because of the mishap with the SD card. Jv I can help you with this part, my 3G dongle is 100% working but on OLPC-AU images so there might be some small differences here.

SD Card bug? XO 1.75 (Repeat post)
Bug? A SD card, with a .Rpm file, crashes the XO whereas any external device should only be used as a booting device if there is a boot image in it or is this an assumption in XO? I re-flashed the XO but the Linux installation needs to be re-done.

Re: Best way to use SD card to increase XO-1 space
What is your problem in upgrading? Problem with your network bandwidth?

We do have upgrade plan but not anytime soon. Our educational software EPaath has grown to whooping 503 MB and thus we are desperately in need of some space. We would want to test one mini deployment with SD card. So I'm wondering what the best way would be to use SD card to increase XO-1 storage. My initial idea is to softlink /home/olpc/Activities to SD card. Any comment, suggestion, feedback?
