It doesn't look correct to me. Here's my understanding: The task of this function is to create a new offscreen memory allocation of a certain size. The function goes through the list of existing allocations, looking at each entry. It calculates how much free space there is inbetween one entry in the list, and the next one. If there is enough free space, the new allocation can be inserted at this point. Otherwise, we have to carry on iterating through the list. In that specific section of code, gap is computed, in 2 stages, to be the amount of bytes inbetween the list entry currently being examined and the next one. if (ptr-next == NULL) gap = pGeode-offscreenSize + pGeode-offscreenStart; else gap = ptr-next-offset; This is the first step. It is setting the gap variable to the absolute address where the next allocation starts. In the first branch, we have reached the end of the list, therefore our upper bound is the top of the offscreen memory. In the 2nd branch, there is a following member in the list, so our upper bound is the address of where that memory allocation starts. And the offset variable is always absolute, so this is the correct calculation for the upper bound. As the 2nd stage of the calclation, the lower bound is considered (the end of the allocation currently being examined) to produce a final value of gap that represents the number of bytes inbetween the 2 consecutive list entries: gap = gap - (ptr-offset + ptr-size); To me, everything looks correct before your patch.

To simply transfering the data to/from the drives would require two drives reading continuously all the time at each end to read the data being received and two drives writing continuously to write the data being sent now, this isn't taking into account the horrible latency in this network connection ;-) but it means that if there is much of any transportation the data can be moved around to make it available. this won't work for interactive services, but it will work for e-mail, data requests, etc. now this is obviously overkill and beyond what is reasonable to try and implement for one data link in the wilderness, but this sort of thing is being done today, in first-world countries to move large scientific datasets around. 20 drives cost ~$4k, shipping them 2nd day will cost ~$200/shipment so shipping this 15 times in a month is ~$3k and result in ~2Gb/sec in bandwidth. you won't get 2Gb/sec in connectivity for this price (assuming that you can get it to your location in the first place) David Lang cheers, Sameer Even wireless service is beyond the reach of rural villages without massive government help, not likely to come about where it is needed most.

Brief testing of OS10 (F11 for XO-1)
Hi, A few observations running OS10 on XO1.0 with latest XO1 firmware: 1) After about 10 minutes (did not measure time exactly) , all input from keyboard and keypad stops. Interestingly, mouse plugged into USB still works. I assume this is because of the Power saving (first of the 2 options) is on. But: 2) By default, Power saving first checkbox is on. But it does not persist when set to off. 3) Interestingly, recording sound in Etoys works (freezes on OS43 and higher on XO1.5, see https://dev.laptop.org/ticket/9724). milan ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Actually I think the hands are all doing a very good job. It's the head that needs attention. One thing does interest me however. the comment it plans to open the architecture of the device to allow any other PC maker to take over the project. Is this in the realms of possibility for the XO-1/1.5? Specifically, would OLPC allow a 3rd party to manufacture a system with their own motherboard using the XO-1 case, battery and screen. Perhaps with a colour change to make it distinctive as another product. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: [Server-devel] Various / PDF resources in Moodle
Martin, Regarding pushing activities, I agree that putting them on the XS to allow the users to manage themselves is the best way. If a teacher wants to make sure that all have it installed, they can always create a folder with the activity uploaded to make it unambiguous. A Todays files folder would be useful, with the teacher directing children to it using sharing Bookmarks (Browse), so they have only to join the shared activity and then click on the Bookmark - 2 clicks to the resources for the lesson. 3 questions, (1) what happens if the version on the XS is different (higher or lower) than a version one already on the XO? Do you get duplicates or does the latest downloaded/run version preside? (2) how can one upload an activity to a folder on the XS from an XO? (3) What is the location on the XS of site files and course files, in case I want to load stuff manually? Here is a combined report on several related non-critical issues. Firstly, I took note of your suggestion and updated my four XOs (2 B4s and 2 C1s) using 802/2QE41 and the latest version of the activities. I upgraded all of them using the same memory stick using the fresh install method (four game keys on boot). So they should have been identical software wise. I discovered two issues in this process. (1) It's difficult to know which are the latest stable versions of activities as the OLPC and Sugar activities pages differ (unless I missed the small print). Sugar has more advanced versions. However, I noted that you referred to Browse 102 which is the current version on the OLPC wiki for that activity. I decided to use the OLPC wiki Activities page for all the G1G1 core activities and the Sugar site latest versions for the rest. I have yet to test them all but all seem OK so far. SO, I am using Browse 102 and Read 56. (2) At risk of seeming to make a fuss out of nothing, this issue has the potential to cause a lot of confusion and time wasting. After noticing some activities and collections failed to start or appear, I suspected that some of the downloads were incomplete. This was confirmed when I looked at the shell screen that appears at the stage when activities are installed one by one. If there are errors, the activity is shown with an exclamation mark rather than a plus sign. I found several of the files were not installing properly. This I found to be because they were incomplete. The downloads had terminated partway through, however with no indication of anything amiss. I used a download manager and re-downloaded the ones that had failed to install. True enough, they now all installed and I can see all the collections, for instance. The issue here is that in countries where there is unreliable connectivity (slow with outages, as is the case here in Solomons) this will be something people will experience. Can the downloads be provided in a more reliable way so that one knows that one has got the full file? Or otherwise recommend people to use download managers. Now to the other issues. (A) PDFs uploaded to Moodle folders always open in the Rainbow-Daemon dialogue when you left click on the links. If you go to hyperlinks on HTML pages either in my local public folders or out on the net, a PDF file always opens in the Browse version of PDF reader when you left click on it. In all my tests it is fully reproducable using both B4 and C1s. I would prefer them to open in Read activity, which has but it's not a huge problem, they are very similar. One can also Keep and then open from the Journal. But why the rainbow-daemon window? Thanks!

[...] Were these downloads done with Browse on an XO, with Software update on an XO, or on another system? A partial HTTP download normally occurs if a connection is interrupted. HTTP has a feature to support resuming from the point of interrupt. I'm not sure if Browse or Software update are doing this. HTTP has a feature for detecting partial downloads, but the client side (Browse, Software update, etc) has to choose to use it. The HTTP header sent by the server contains a total length value that can be checked against what is received. Both of these features may not work if the internet service provider fails to take the care to support them. -- James Cameron http://quozl.linux.org.au/ ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
