The "slightly less" would be 5:4 as is common on 1280x1024 screens. However, on the XO the screen can be rotated so you get a 3:4 ratio. And e.g. the Classmate Tablet rotates automatically, too, so it's (close to) 10:16 if you hold it upright. - Bert - ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

I am aware of that issue but I am referring a different one.
for whatever reason a canvas pixel is not equivalent to a css pixel so
the following methods of specifying canvas dimensions are not
equivalent:
#mycanvas {
width: 200;
height: 200;
}

Re: [Sugar-devel] SarynPaint: a Java program packaged for the OLPC
If you have a URL for the project I might look at it to see if I could make a Python version, giving credit to the original author of course. If you've been following this mailing list you know there are frequent discussions about what should be included in the supporting environment for Sugar. We've had discussions about WebKit, QT, as well as Java. WebKit was opposed by some because it does the same thing as Gecko, but it we included it Read could support EPub files, which would be a huge win for the platform even if we used it for nothing else. As for QT, apparently there is a lot of educational software already written that uses QT. Neither of these justifications exists for Java, plus Java requires 75 meg for the runtime which is a lot of disk space for the XO although it might be tolerable elsewhere. I once wrote a program to do standards checking on COBOL code. I wrote the first version in Turbo C, then rewrote it in COBOL because it needed to run on a mainframe and that was the language the mainframe needed it to be in. I actually liked the COBOL version better, for reasons that would be hard to explain. IBM did offer a C compiler for the mainframe, but nobody wanted it, not even me. COBOL was the right answer.

[Sugar-devel] What operating system should I put on the donated computers for SoaS at the GPA
Anurag a CS student at BU, my husband, a CS grad from MIT and I, a techie never give upper, are going to be working on Monday to take the pile of computers in my house and prepare them for installing in the GPA school on Weds. We will be wiping all the hard disks and putting on something else. Can I put install some version of the boothelper on the hard drive so when it boots off of the hard drive it automatically looks for a USB? I think this would be preferred especially for older computers that don't let us set the bios for USB boot preference. Perhaps with newer computers we should install Sugar locally and make it the "Room 33" user so that guests can get access with out a stick. Thoughts? help? Got a good answer?

A boot menu could allow this. Will require at least some config file investigation/changes. Also, I understand the the current beta for SoaS 2 has a method to install to a hard drive and it would be best to remain compatible with that. Unfortunately, I know nothing about how it works. > Got a good answer? Put it here for future > deployments: https://answers.launchpad.net/soas/+question/81627 > We will also use this for tracking what I do and documenting results. The floppy boot helper (using kexec-loader) that I've been working on with you does the initial boot via syslinux. Respinning it to boot from a hard drive is therefore theoretically easy as syslinux can be used on hard drivers as well as floppies. However, how to create an easy to use UI to get it installed to the hard drive isn't immediately obvious to me. Alternatively, the current CD helper uses isolinux for it's initial boot which is part of the same suite of programs as syslinux. Syslinux can used more or less as a drop in replacement for isolinux. Therefore the CD helper method could also be theoretically respun, but with identical install issues as the floppy helper. Bill Bogstad Technical notes: A fundamental difference between the CD helper and the Floppy helper is that the CD helper actually contains the SoaS kernel and ramdisk and only points to the Flash drive to get the root and /home filesystems. The floppy helper actually reads the SoaS kernel/ramdisk off of the USB stick at boot time. As a result, I believe that the floppy helper is less likely to need to be respun for new releases of SoaS. OTOH, the floppy helper makes no use of the BIOS to read/find the SoaS and if the floppy helper doesn't have a driver for hardware you want to boot from the BIOS doesn't help. ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

I mean that if there is agreement about mission statement of proposed feature(i.e. w/o any technical details of implementation) it will be much easier to find consensus with particular implementation.

You should be able to use any "switch" with as many ports as you have computers. For example: 5 ports: http://www.microcenter.com/single_product_results.phtml?product_id=0257750 8 ports: http://www.microcenter.com/single_product_results.phtml?product_id=0294506 16 ports: http://www.microcenter.com/single_product_results.phtml?product_id=0282106 (The Microcenter in Cambridge happens to be my usual place to buy this sort of electronics.) All you should need is a switch like that, and one standard ethernet cable for each computer.

Re: [Sugar-devel] What operating system should I put on the donated computers for SoaS at the GPA
Our short term goal is to on Monday prep 5-10 computer to put into the GPA classrooms on Weds. So we don't need super simple or something we never have to upgrade, we will have lots of access to these computers. Also we don't need computers to be both boot-helpers and have a Guest Sugar system on them. They can be one or the other. This week is about what we can do this week. Hopefully this experience will lead us to a super simple installation that we can use for donated computers and put it into kids homes without having to worry about how we will upgrade them. Thanks!

It is hard for me to believe that the problem is with the choice of switch. Switches are commodities; they're interchangeable and virtually identical in functionality. Your earlier description suggests that your laptops are not configured for local collaboration at all. In particular, it's possible that Avahi is not running. Whether the Avahi daemon is initiated by default, and how to start it, varies between distributions, so I can't advise you on that without knowing more about your configuration. --Ben signature.asc Description: OpenPGP digital signature ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

I can probably find a way to generate and install a hard disk boot helper for SoaS by Monday. Whether it is based on the current CD or floppy helper will depend on on which is easier to do. I know nothing about guest Sugar systems and wouldn't even attempt to meet that kind of deadline.

The same sticks collaborate locally at the GPA. Note that not seeing anyone in the neighborhood, and seeing people but not having all shared activities work all the time are probably two different bugs. We do sometimes have trouble with seeing activities at the GPA, but we always see the other people. Thanks!

Caroline Meeks wrote: > The same sticks collaborate locally at the GPA. That's certainly very strange. I still think it's more likely to be a software problem than a hardware problem. The only relevant difference I can think of between GPA and a switch like this is that at GPA, there's a DHCP server handing out addresses. On a simple switch with no internet connection, the computers have to adopt link-local IP addresses (169.*). One possibility is that, in the absence of a DHCP server, the computers are not correctly acquiring link-local addresses. Bill can confirm this on Monday, I guess, by looking at the IP addresses shown in ifconfig in the no-internet configuration. > Note that not seeing anyone in the neighborhood, and seeing people but not > having all shared activities work all the time are probably two different > bugs.

Even a crossover cable between two machines would be enough to test the system. My current best diagnosis is that the dhcpcd on Strawberry has somehow been configured without zeroconf, so it does not acquire a link-local address and bring up the interface in the absence of a DHCP server. I freely admit, though, that this diagnosis doesn't make a lot of sense, because Fedora has generally embraced zeroconf and Avahi, and there's no reason Strawberry should be different from stock Fedora in this regard. signature.asc Description: OpenPGP digital signature ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

In general, being "on the same segment" as another user means that you can communicate directly with that user. "Directly" is used here in the Internet Protocol sense: A and B are on the same segment if the total number of hops between them is 1. In this specific case, "on the same segment" is used to mean "can communicate via IP multicast". On most LANs, routers are not configured to propagate multicast messages between segments, so the local collaboration (which uses multicast) can only work within one segment. If you configure your routers to propagate multicast messages between segments, then link-local collaboration will work over the whole LAN... until you have so many users that the required bandwidth exceeds the network capacity. signature.asc Description: OpenPGP digital signature ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

[Sugar-devel] Sugarcamp Bolzano 2009
It looks like it is time to plan another SugarCamp[1]. This time we have an invitation to spend the 7th to the 12th of November in Bolzano, Italy. It looks like six completely free days to work together on Sugar! The coolest part of this camp is the fact that we are collocating with the GnomeHackfest. It looks like .86 is going to ship on or about September 18th. That leaves us with three weeks to think of new things which are needed for 0.88. and then 6 whole days to work. Because we have six days, the time pressure is much less than it was in Paris. But it would be great if we could continue the same level of productivity. Let's handle the scheduling similar to Paris. The entire week spent in one to four hour breakout sessions and work sessions. Put your ideas down under topics on the wiki page and when we get to Bolzano we can figure out how to schedule things. As always, the main goal is to make Sugar great. david 1. http://wiki.sugarlabs.org/go/Marketing_Team/Events/Sugarcamp_Bolzano_2009 ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel
