Re: embedding evince

Hi, I'm afraid we don't have any written docs like that. If I had to do another activity that used the evince python bindings, I would first read Read's code and then see if the existing bindings in evince.def are enough. You can find some apidocs about that in the evince C sources. If you need to add bindings, see how evince.defs is done and send patches. Also, note that we are shipping a forked package of evince containing a few patches to evince itself, some work to put the evince code in a shared lib, plus the python bindings themselves. All this should be upstreamable, but nobody has found the time yet. If someone wanted to do such contribution, would be very welcome.

A short 8.3 in November this year to get in sync? Fedora releases in November and May. We could plan to release in late-November (just before Thanksgiving) and June. To sync up, I think a short 8.3 might be pushing it a bit; I'd suggest taking the 10 months between August and June and making two 5 month release cycles, so that we release in January (9.1, based on F10) and June (9.2, based on F11), and are then synced up for a regular November/June schedule. That's just my first shot at a proposal, though: there might be better ideas out there. In particular, the Fedora's November release date was specifically designed to avoid Thanksgiving and winter holidays in December. I'm a little concerned that (a) if we follow Fedora too closely it will be too hard to have Fedora making final release changes at the same time we are, but (b) if we lag too far then we'll be freezing at Thanksgiving and releasing at Christmas, which seems... suboptimal. As an alternative which avoids the Christmas trap, we could consider 3 releases a year, in June, October, and February. The June and October releases will be based on the Fedora May release, and the February release will be based on the Fedora November release. This gives us one tight integration in June where we're using the very latest Fedora bits, one free pass in October where we can worry about our own features and not track Fedora, and a leisurely February release with plenty of time to sync up with the changes Fedora's made since November. I think I slightly favor the regularity of the November/June schedule, with the understanding that our November schedule will be tighter (and with a sharper cliff on the other side) than the June schedule. We might be more aggressive about pruning unready features early for November, for example. Here's the historic data on Fedora release dates (note that the November/May schedule started around F7). http://fedoraproject.org/wiki/Releases/HistoricalSchedules If we had ambitious release engineers, we could plan to roll up joyride into Alpha, Beta, and Preview releases synchronized with Fedora as well, but I'd prefer we demonstrate that we can get our basic product out the door on schedule before worrying about other possible end-user products we might provide. --scott -- ( http://cscott.net/ ) ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: Olpc3 vs Joyride
While I would have no problem doing this, it is just worth noting that Csound for olpc (aka olpcsound) is built with different scons options, so making a spec for csound and olpcsound might be tricky. Yes it is a subset, but a special subset. In addition, I am not the maintainer of the csound packages in fedora. There are a number of issues that require attention in order to create an updated csound package (eg. 64bit systems built etc), which are not related to OLPC. Since my time is limited, resolving these would mean the olpc csound package would be delayed. My priority being getting the subset ready meant not diverging to maintain csound on Fedora, which of course can happen in the future. Also, I needed to be sponsored and so I wanted to keep things simple and tidy. I did not know there were people willing to take on the maintenance of csound for Fedora. If I knew I would probably not have troubled myself. I find it amazing that instead of offering support, people tend to criticize you for taking a thankless task onboard. I wish instead of just talking, they went out there and did the job; I am happy to pass on the maintenance of olpcsound, csound-olpc or whatever name you find more appropriate, to whoever is not happy and thinks he/she can make a better job of it.

In general, I think this is the fundamental weakness of the first draft: it mentions that a release consists of core OS + other stuff but really only talks about dates deadlines names for the core OS. I don't think the solution is expanding our scope so that OLPC is responsible for releasing every country's other stuff along with 8.2 at a single release date. I think the solution is to be more explicit about where the hand offs are, what the limits of our development/support are, and what processes are used to support local development. We should write into our release process when we gives bits to local translation, activity, and content teams, and when we need bits back from them, esp. for localization of reference activities and content (library-core, Write, Words) and for reference activities which are not maintained by OLPC (Tam Tam, Etoys, Squeak). There may be a separate release document that outlines the steps we will take to support a planned large-scale deployment, including basic QA of their activities + core OS image, converting it to an image suitable for Quanta and shepherding it through their QA process, QA of keyboards and manufacturing data on local SKUs, etc. This timetable is driven by the deployment, but we should set reasonable expectations for what steps are required, in what order, and how much time is needed for each. I'd also like to see quality expectations set, since the success and reputation of OLPC may depend on the success of these large-scale deployments. This is both technical (their release should work) and aesthetic (icons for local activities should conform to Sugar guidelines, the ordering should be logical, etc). For the bits of non-core OS other stuff we do, we should commit to a schedule. When is the first draft of the release notes available? Are the final versions of the reference activities synchronized with the core OS, or can/do they lag it by a week (or two, or three)? After how long does a release candidate become a release? What happens if there is a critical bug discovered in a not maintained here reference activity? Our biggest weakness to date is not knowing when we're done because the core OS is good enough but the other stuff isn't getting done. --scott -- ( http://cscott.net/ ) ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

My code is available at http://git.n0r.org/?p=pygame-nrp;a=summary and is currently pygame 1.8.1 with the addition of a camera module that supports v4l2 cameras that use MMAP and have pixelformats of RGB24, RGB444, YUYV, SBGGR8, or YUV420. Basic usage is as follows: import pygame from pygame import camera cam = camera.Camera(/dev/video0, (640, 480), RGB) # the third argument can be YUV or HSV too. cam.start() frame = cam.get_image() # the frame returned is a 24bit pygame Surface You can also do fun stuff like: http://eclecti.cc/bytes/living-pointillism-a-pygame-webcam-script or more practical stuff like having it track the centroid of a specific hue (green in this case): http://eclecti.cc/files/centroid.py My plans are to add functions like finding the largest connected component, optical flow, and other things useful for computer vision. Currently, performace is pretty poor on the XO; a combination of the Geode being slow and having to convert from 24bit to 16bit surfaces to display any captured frames. The XO is fast enough to capture and blit a 320x240 RGB frame at 30fps, but not at 640x480 or a frame being converted to HSV. I'm not sure how or if I'm going to be able to overcome those performance problems. I'd appreciate any comments, suggestions, or reality checks on improving performance or anything else, or any requests for vision functions to add. Also, I only have the camera in the XO, vivi, and a poorly supported USB webcam, so if anyone could test it on other webcams, that would be great.

Hola Carlos, man is man. You can install it with yum install man For ssh you can set the password using passwd (either for root or for the user). ifconfig is ifconfig, but on fedora, the /sbin directory is not on the ordinary user path, so you must use /sbin/ifconfig, or be root and use ifconfig.

my XO has difficulty with f9
Been running reasonably happily with f7 builds (primarily Joyride 2056). G1G1; Q2D16. When I couldn't stand sitting still any longer, I installed yesterday's Joyride (f9). Ran almost acceptably (needed manual intervention during boot). One problem I had was that my USB removable storage devices (except for my SD card) were not being recognized, neither by OFW nor by the system drivers. The insoluble problem was that when I installed a build (e.g., Joyride 2089), the first boot would work -- but thereafter every attempt at booting would stop somewhere. [If I used the 'check' key to get out of pretty boot, the booting process would always stop after the console message Starting anacron:. If I used manual intervention to get to the text console, after the Starting anacron: message there would be periodic msh0: link becomes ready messages, sometimes interspersed with messages complaining about bad checksums in the jffs2 filesystem -- but sooner or later the XO would just sit there.] My problem is that I do not know if I did something after the first boot to cause this situation, Nor do I know how to correct jffs2. Each time the XO would not allow me to boot, I re-flashed the entire nand. Eventually got tired of it - am now back to running f7 builds. mikus ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Samba's Talloc and mem pressure on the XS - tinkerers?
Opening post cross-posted to devel@ but please reply only to server-devel@ :-) Couple weeks ago we had Tridge @ 1CC and while jg and I cried about memory pressure on XO and XS, he suggested we try talloc, and monitor actual memory usage with the newfangled smaps. This is something I'm very keen on doing, but definitely haven't been able to work on yet. And it's orthogonal to everything else we arew doing. Some interesting things to tackle - Have a look at Apache's memory usage when serving something like moodle or mediawiki, using ps_mem.py - see how apache processes do _not_ release mem back to the OS mem pool after serving a page. (They will when they are reaped, but that's a different question...) - Compile talloc and run the nasty apache/php combo with LD_LIBRARY_PATH pointing to talloc - hopefully apache, php and the php extensions behave well and actually release memory after the page is served. - Compare performance (ab is good enough) of php execution when using talloc, vs using the normal glibc malloc+apache set to MaxRequestsPerChild 1 (reaping every child after serving the page). Bind with talloc might be another trick to play with, though perhaps that's a lost cause, and a clean cut to dnsmasq might be better.

Re: OLPC-Update + RPMs WAS:Re: OLPC XO Opera browser as Sugar activity
We separated out the activities so that we could push the testing and localization of activities out to the country. How many activities can they test? As many as they have people and time for. It is in the deployment guide (and starting to get good discussion from sales/deployment people) that a country must take responsibility for choosing, testing, and localizing activities and content. We will make the combined OS+Activities image for them, but our testing is limited to ensuring that the signed image loads and we'll do the equivalent of 10 minutes of testing (this is not exact, but meant to give you the idea that we won't spend days or even hours testing each customized image -- ideally this testing is automated so we can do 30 different country images in a day or in parallel). The country has to have done the testing to enusre proper operation of the activities and the correct language, etc.. OLPC's testing needs to be limited or there is no scalability. In the same way, we have set a precedent with Uruguay, that if they country wants to make changes to the code base that they need to send a developer to 1CC to learn how to work with our processes, our developers, our repositories, etc. and to make sure their features and bug fixes get in releases. And they have to do their own testing. If they do all that, then we will sign their builds, do the same '10 minute' test and be able to support them when they have to make more changes in the future. We won't fix their code, but we will encourage them to contribute as we do other developers. Note: for the G1G1 program OLPC has to choose the activities, ensure that the testing gets done (hopefully with community help), and take some responsibility for the activities that we ship.

Re: [Server-devel] Can't get XS to do nameserver/resolv.conf properly, unable to access URLs
Martin, I got the name serving (DNS client) working. Basically I had to grep my entire /etc for instances of random.xs.laptop.org and change that to the correct value for our ISP provider. It seems that service network restart doesn't re-read the updated /etc/resolv.conf, and so rebooting is required. One key change is creating /etc/sysconfig/olpc_net_config file. This file indicates that the system has already been booted before and not to over-write any IP configurations that are generated on the first boot with DHCP values for eth0. We have static IP, and specified BOOTPROTO=STATIC, but the XS image keeps over-writing what I had done previously, only to find out it did this because olpc_net_config never gets created. By manually creating, it stopcs these other actviities. Thanks Tony Pearson Senior Storage Consultant, IBM System Storage?

Bind with talloc might be another trick to play with, though perhaps that's a lost cause, and a clean cut to dnsmasq might be better.

I seem to be losing my memory - it was alloc_mmap. After this correction, let's go back to server-devel@ :-) Tridge says: no, I wasn't talking about talloc. Changing to talloc is an interesting project, but it is not trivial, and doesn't help at all with reducing memory usage (it aims to make programming in C less error prone). I was talking about alloc_mmap, which is a malloc replacement that has low overhead and agressively gives memory back to the OS. See http://samba.org/~tridge/junkcode/alloc_mmap/ Whether it will help with apache depends on the allocation patterns apache uses. I'm sure it will work with apache, but you won't know if it will reduce memory overheads without trying it. Also, I think apache uses its own pool allocator internally, which means you may need to graft alloc_mmap into apache rather than just using a LD_PRELOAD in order to get the most benefit.
