Re: [Wiki-gang] [Testing] Activity Set for 9.1.0
To clarify - the default image used in manufacturing contains Activities
(the same ones shipped with G1G1 this year), right?
My understanding is that (the image we ship) = (software release) +
(customization key), so Chris's statement that our software releases
don't ship with Activities is correct, but Greg's statement about
starting Activity selection early for 9.1.0 makes perfect sense.

Hi Chris,
When this release is done we will update the default image used in
manufacturing.
All of our deployments except one currently take the default image. Many
change it (usually adding more than subtracting) after they get the XOs
in country but they start with our factory image.
We will also offer people an option to clean install with a set of
activities like we did in 8.2.
Let me know if that's not clear or you need more info.

Hi Greg,
Hi All, Learning from the last release, I want to start activity

Our software releases don't ship with activities, so I don't understand
what's being selected here. We didn't choose a set of activities to
ship with 8.2.0; we chose a set of activities to ship on a G1G1 image.
Each deployment creates its own conjunction of {XO release+Activities},
with G1G1 being one such deployment when it's running.
Could you elaborate on what the list of chosen activities would mean
this time around?
Thanks,

This says nothing about the functionality of the Home screen. Experience has indicated that people (particularly kids) more often than not would prefer to resume the last thing they worked on, which led us to the proposed bi-modal home view. * it would solve Pablo's problem (this works today, resuming an already opened journal entry just switches to that activity) It solves his problem /if/ his problem was simply attempted prevention of accidental duplicate instances. If, on the other hand, his problem involved a technical constraint which prevents two instances from running simultaneously, it does not. We need to hear more about the root issue. * no more unwanted Journal entries (one would be reused all-over) This isn't quite the right idea. We wish to give preference to continuing work, but that's certainly not the same thing as saying that there is just one instance. No entries are reused. Instead, the most recent instance is simply shown by default, adjacent to a number of older instance, as well as a new instance. In any case, I think the better solution to reducing unwanted entries is to encourage naming, and provide a don't keep option in the naming prompt upon closing a previously unnamed unkept activity. * creating a new Journal entry would be an explicit action (need UI for that) Right. The current proposal is to provide the alternate functionality (start new) in the contextual menu (or by holding alt while clicking). That last item is the only problem I can see - in the activity one would need a start new entry button, just having this as optional menu item in the home view is not enough. The semantics would be just like the keep a copy button now, but also reset the activity to a blank slate. Hmmm, I'm not sure about this. I think it's important for the instance model to maintain that launching the most recent instance does indeed resume that specific instance. I think the in-place new document breaks this idea, harkening back to the old model of applications and files. If the upcoming datastore work focused on versioning as much as legacy file support, we would not even need that button (though it might still be convenient to have). Older instances would then readily be available in the Journal and could be resumed from there. Exactly. This is small part of the reason we didn't implement this yet, too. Versions would make it less problematic if a child resumed a recent activity, actually wanting a new document, and then destructively edited it. - Eben - Bert - ___ Sugar-devel mailing list [EMAIL PROTECTED] http://lists.sugarlabs.org/listinfo/sugar-devel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: Way to tell if it is an XO
Hey Michael! I will give you guys some background info on the project The goal of the proyect is to provide some way of communication beteween the children who have an XO and their parents and family. Since most of the parents don't have a computer nor internet access, we determined telephone is the best way to reach them. Some of them don't have cellphones either, but line telephones, most of them do. My partner on this project and I work for a company that does text to speech and SMS2 to Phone Call services, so we are going to use the infrastructure for this project. So we are developing a simple client app for Sugar and the xo, in order to let children write a message and send it to their parents. The message will be translated to speech and, and the parents will recieve it in a phone call on their home line or mobile device. The message will be sent using web services and the transport will be SOAP over HTTP although the goal of the project was to base the authentication system on XMPP and also transport SOAP over xmpp. But for the prototype we aren't going to use XMPP. We plan to offer this service just for the children and the security and authentication concerns are not to let anybody else use the service. The only threat or attacks to the service is someone pretending to be a children with an XO to send messages since it is not free of charge for everyone, that's why we tought of WSS to probe authenticity, integrity and also that the message was originated by the sender. There is no threat on the XO's end to my knowledge since it is a one way only communication system ( Actually we did a reaserch for University and came up with XMPP using Jabber server to be the best way to achieve bidirectional communication) but this is a far bigger project because we need Jabber servers and authentication schemes to be used globbally here in Uruguay and that is far from happening I think.) Finnally, this project is only a prototype and it will be very difficult to deploy nation wide since there are commercial issues to settle. Anyways, hope I have been clear and thanks everyone for the support.

Ed is the release manager and its up to him in the end. Action item - Ed to set a date for start of Trac scrub. He will tell us that date by Friday 12/12. - General There were some complaints that we don't have a plan or that we are spending too much time talking about stuff instead of working. There were also complaints that we don't reach consensus on a subject before moving to the next one. There was no consensus on the agenda but people wanted to make the meeting longer so that everyone's opinion could be heard. Just noting that for the record. My proposed agenda is below.

Re: [PATCH] cafe_nand: remove busy-wait loop
So, the transfer rate dropped from about 9.6mb/sec to about 5.3mb/sec. I was afraid of this. Flash is pretty fast, and there's almost no parallelism available in it (e.g. you can't queue up a bunch of reads to occur when the data rotates under the heads, or start a seek early). Thus it's mostly worth sitting and waiting for the chip to finish, rather than making the CPU try to do something else. It all happens at chip speeds -- and OLPC designed the CaFE chip to run as fast as the flash chips and memory bus can run (because the Geode's native flash support, for some reason, didn't go that fast). [Note, however, that the Marvell spec for the chip doesn't give ANY speed specs. It does say it might be possible to run its PCI bus at 66 MHz rather than 33 -- which do we do?] I really think we need to separate the effects of filesystem compression from the effects of Flash storage. Other reports show systems being able to do many thousands of transactions per second to SSD (flash-based disks), but we don't come anywhere close to that. Why don't we? Nobody knows. There is a trivial way to make an uncompressed NAND image. Take an existing build's tar image, extract it to a directory, use the same mkfs.jffs2 command from the standard build log, but add --compression-mode none to build an uncompressed image. Burning that into NAND will let you test uncompressed reads. That will give you best-case reads, too, since all the data for a given file will be contiguous. Perhaps there is some sysfs knob that will also let you turn off compressed writes. It's unfortunate that there's no block device way to access Flash chips in Linux without using a filesystem at all. It's much easier to measure and tune I/O performance without a filesystem first, then see what (filesystem or driver) optimizations are required to make a particular filesystem fast on that device. John PS: During the long delay while the CaFe is erasing a block, it can do reads from other blocks (but not this one); do we do these in parallel? ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: Wine activity
That's awesome work! I was able to install Wine and use it, including firefox and a win32 application I had previously build using mingw32 under Linux on another PC and uploaded to a webserver, and then downloaded using firefox inside wine. However, I did notice the following oddities: 1. When I later resumed the activity from the journal, the wallpaper was gone and nothing worked, although the start-menu items for firefox were still there. 2. It was not clear to me how to save wine's state to the journal. 3. At some point the usual 'leave full-screen mode' icon appeared in the upper-right corner, but clicking it seemed to have no effect other than to make it disappear, i.e. no sugar UI appeared and the desktop size did not change. 4. Wine crashed when I used Firefox's download manager to open the location of a downloaded file (winefile appeared briefly, then the whole activity crashed.) I have no idea why yet, but perhaps there is some information left in a log file somewhere I will find. On the bright side, this means it's fairly trivial to run at least some windows-only software on the OLPC now, which is great when there's not yet a Sugar or Linux version. -Ben On Tue, Dec 9, 2008 at 12:02 PM, Vincent Povirk [EMAIL PROTECTED] wrote: The Wine activity has advanced to the point where I think it's ready for testing by actual users.

Hi, I've been playing around with this a bit, and I still can't figure out the xol files. When I download http://wiki.laptop.org/images/2/28/Yay-Bee-See-9.xol In Browse, it does get saved to the Journal, and when I start the xol file from the Journal it launches Browse with the main HTML file from the collection, and a subsequently launched vanilla Browse includes yay-bee-see in the images section of the Library. However, even after I keep both the .xol file and the Browse session, rebooting the machine causes yay-bee-see to disappear from the images section of the Library (and the kept Browse session to show a File Not Found message) until I open the .xol file again.

Re: [Sugar-devel] Wacom Bamboo with XO?
Wade Brainerd wrote: The only catch is that the drawing output lags the tablet strokes by quite a bit. My guess is that the event processing cannot keep up with the data rate. I seem to remember that there was a driver configuration related to that which might be used to throttle down the fire hydrant. The mouse events go at a higher priority than the expose events, so the screen update waits until you stop moving if it gets behind. But, at the end your entire stroke should appear. I would be concerned about reducing the update rate, it might lead to less accurate drawing. It is true that reducing the update rate would lower the pen position resolution of lines...but the Bamboo tablet has a linear resolution of 2400+ lines per inch which is about 12X the XO pixel resolution and 24X your 2X reduced drawing canvas. As a result, even with skipping pen deltas of 24 or less the pen output events will still be at the finest drawing precision. This is not even including the fact that the brush is more than a single pixel wide typically. If you add an entry under the first wacom Xinput entry in your xorg-dcon.conf file like: Option Suppress 60 you'll get much better drawing response with the existing infrastructure. I tried 10-72 and to keep up with faster sketching or larger brushes, the rate needs to be at 50 or greater. After the above edit and a 3-finger-salute to restart the X server on the XO, Colors! basically worked well with the tablet. There is a command line configuration program (xsetwacom) that could be used to configure Wacom tablet settings without editing the xorg-dcon.conf file. I don't know if a restart of X would then be required. It might be possible to base a control panel interface calling the underlying utility per Tomeu Vizoso's previous mention in this thread. To improve beyond the Suppress technique will require improved event handling optimization in colors.py. My guess is that the best approach will be to encapsulate tablet specific handling at a lower level for efficiency. I've got some optimizations planned to the C module which should make it better, and I think there are some bottenecks in the X server that slow things down and could be fixed, but my recommendation for now is to draw slower :) Cool! BTW, Colors! version 11 did not appear to have the photo snap capability. Was that removed? See Nirav's response. I'm also planning to add Paste support so you can just snap the photo in Record (or whatever) and paste it into the Reference image, then paint over that. I tried the earlier photo snap and it was awkward to toggle the underlying photo image. It would be more helpful if the photo could be drawn over as if on tracing paper.

If it were to be extended a bit at the top then the Frame would be easier to get to from the tablet only. Maybe one of the Wacom buttons could be assigned to the Frame key event? Can this be done in xorg-dcon.conf? I've got an old serial Intuos that I'll try to get configured this weekend. I'll let you know how it goes... If we get this working, maybe Amazon could add a People who bought this item [the XO], also bought this [Wacom Bamboo]... :-) Great! Thanks again for the feedback, I'll try to release a new version before long with these suggestions. Cheers, Wade ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

New F series firmware release
I've just cut the first release of the F series firmware. New cool nifty OFW feature like NANDblaster, USB cdrom support, and other goodness. But the primary reason is the restructured EC code. Paul Fox did a ton of work re-organizing the EC code and cleaning up lots of cruft plus getting the system working under Wine. Many thanks to him. The only new EC feature is a quick blink before power off. New suspend code turns off the WLAN LEDs so it was really hard to tell if you had just suspended or if you were off. Now if you want to power off just press and hold the power button until you see several quick blinks and then the LED will go dark. You are now powered off. But since lots of code was moved around and various header files merged I expect to find some fallout. Hopefully its not too bad. -- Richard Smith [EMAIL PROTECTED] One Laptop Per Child ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: [Server-devel] Amateurish Workaround to Get Bonding to Work With eth1

I am starting to agree -- we are either seeing an issue with timing _or_ a configuration issue. Perhaps our config for eth1 is broken. It'd be strange since I tested it quite a bit in the run up to the release, but it's also true that I was making subtle changes to the very same configs. Good news is: I can repro the problem on a machine I have here. Could you try adding HOTPLUG=yes to the ifcfg-eth1 file I spotted exactly the same difference and tested it -- does not seem to work. Hope to get to the bottom of it.

On Wed, Dec 10, 2008 at 6:09 PM, Martin Langhoff I spotted exactly the same difference and tested it -- does not seem to work. Hope to get to the bottom of it. Alright, fixed. Credit to Anna and Jerry for narrowing down on the issue. The actual problem is laughably simple -- late in the dev cycle of 0.5 a typo sneaked in. A minor edit of ifcfg-eth1 fixes it, see: http://dev.laptop.org/git?p=projects/xs-config;a=commitdiff;h=acd64ab3d2342fbda08a944e31878db6b3b563f2 In any case, you can grab the rpm with the fix from http://xs-dev.laptop.org/xsrepos/testing/olpc/9/i386/xs-config-0.5.7.g11aaacf-1.noarch.rpm or perform yum --enablerepo=olpcxstesting install xs-config thanks everyone -- specially Anna -- for you help and patience. cheers, martin -- [EMAIL PROTECTED] [EMAIL PROTECTED] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
Re: [Server-devel] XS 0.5 Second Attempt at eth1
2008/12/5 Reuben K. Caron [EMAIL PROTECTED]: After doing a clean install 4 times and dhcpd not starting Thanks for the dedication and the report - I managed to repro the issue as you describe below. ... When I cd /etc/sysconfig/olpc-scripts ./domain_config xs5.org It creates the xs_domain_name file in /etc/sysconfig/olpc-scripts/ that's the wrong landing place, as you recognised. The current working directory should not affect us. The patch is here: http://dev.laptop.org/git?p=projects/xs-config;a=commitdiff;h=ae030b75d85fa46962134424667dfa6fb7eba5cf and there's an xs-config 0.5.8-biglonghash.rpm on its way to the xs-dev server. Not quite in the same league as the bonding issue, but a good thing to spot and fix. cheers, m -- [EMAIL PROTECTED] [EMAIL PROTECTED] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
