Open source and diagramming survey
Dear open source contributors, I am Eunyoung Chung, a Masters student working with Dr. Jensen at Oregon State University. We are currently doing a research project in collaboration with Dr. Truong and Ph.D student Koji Yatani at University of Toronto. Our goal is to understand how contributors communicate and collaborate in Open Source Software (OSS) projects, including diagramming practices. We are seeking volunteers for a quick survey on this topic. Any person who is actively working on a OSS project is eligible. The survey takes approximately 10-15 minutes, and the 5 volunteers will be picked to receive a $30 Amazon gift certificate. Your participation is anonymous (unless you consent to have us contact you) Here is the survey address. https://secure.engr.oregonstate.edu/limesurvey/58564/lang-en We really appreciate your help! ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

[...] Sorry, perhaps I didn't explain myself adequately. One of the uses of the laptop is in teaching of electronics and control systems. The current model has an analog input on the microphone socket, but digital outputs require the addition of external USB devices [1]. If there is a way to switch the 5V supply to individual USB ports, and if that was exposed in software ... and it is $0.15, then the question isn't really what power will it save but rather does the potential use justify the cost? The USB ports could then be used as switchable 5V sources, with the current driving external devices directly, with the data leads of the USB cable disconnected. I don't know of anyone who plans to teach electronics and control systems though. -- [1] the analog input can be used as a digital output with additional circuitry that detects the switching of the bias voltage, but that is quite complex for a student to comprehend. -- James Cameronmailto:qu...@us.netrek.org http://quozl.netrek.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

from Peru, sugar in DEBIAN
My name is Sdenka from Puno Peru, since one month we are using Debian at Glorioso San Carlos High School in PERU. We installed the sugar and 10 activities including in Debian packages, then added ETOYS, SCRATCH AND LOGOTURTLE. I need the other activities' source code to compilate in Debian to use and test them with teenagers students this year. Our goal is testing and then use Debian in elementary school which didn't receive LAPTOP XO, but like to use the wonderful activities FOR EDUCATION.

Re: XO Camera
Hi Jon, [Sorry for the slow response, I am losing the battle with my inbox in a spectacular way...] I've been playing with rawhide on the XO this morning now that I've finally got it booting of the SD easily and regularly. It seems the camera doesn't work either in the record app or in cheese. Looking at the dmesg output it looks like the sensor isn't supported in the rawhide kernel. Is there a kernel patch that needs to go upstream for support for this as well? dmesg output: ov7670 0-0042: chip found @ 0x84 (cafe_ccic) cafe1000-ccic :00:0c.2: Unsupported sensor type 0x14cafe1000-ccic: probe of :00:0c.2 failed with error -22 This support should be already upstream. I'd try building the module reverted to Linus cd257a6f4dd, in case one of the recent commits to ov7670/cafe_ccic broke detection. Jon, any ideas what this might be? Which kernel are you running? The kernel is the rawhide variant 2.6.29.1 from about a week ago. Hans Verkuil (CCed) made a lot of changes for 2.6.30; I meant to try them out, but, in the time I had available, I never did succeed in getting a contemporary system running on my XO. So there is a lot of untested code in that driver in 2.6.30; given the nature of the changes, a detection failure seems like a likely problem. OK, not sure whether the rawhide kernel has pulled any .30 changes in but its always possible. I hope not. To be honest, I can't imagine them doing that. The fact that it's seeing something at 0x84 is a little suspicious. Hans has an XO now; I'm not sure how far he's gotten in trying things out. I did have a power plug converter for US - EU power sockets, but it was apparently made by people who never actually seen an EU power socket since it didn't fit. So I need to get myself a proper converter first before I can try and test 2.6.30 on it :-( Regards, Hans Cool. Thanks for the update.

The XO-1 has hardware-accelerated XVideo, including YUV-RGB and scaling. Are you talking about hardware acceleration for the internal stages of video decoding, a la XvMC? Tests on a 1.0 GHz C7-M (the processor in XO-1.5) indicate that software-only rendering should be fast enough to play DVD-resolution video and audio. --Ben signature.asc Description: OpenPGP digital signature ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
