Good question. Neither is the right one. In a XS driven net, both are
equal. In a XS-on-the-internet situation, the public XS may decide
to not offer backup service. Of the 3 (moodle/webapps, xmpp, backup),
backup is the most burdensome on the server.
So I think there is a (very marginal) advantage to using the jabber
server. But the most important hting is that 0.82.x and master use the
same, so whatever you do, both should use the same...
Our registration URL is REGISTER_URL = 'http://schoolserver:8080/',
wouldn't the right Domain than be 'schoolserver'? Since the cookie is
about the registration with the schoolserver this makes most sense to me
(the jabber server could be somewhere else).
(The right fix is to have a 'schoolserver fqdn' entry in the
profile... but that's for the next Sugar dev cycle I guess...)

Is that the only thing that could go wrong? My thinking has been: if

showstopper.
- what bothers me a bit is that you don't get an error when the database
does not exist - sqlite creates a new one actually - so we might return as
well on 'if not os.path.exists(os.path.join(_profile_path,
'cookies.sqlite'))'
Well, all the calls in the try block are sqlite3 ones - if they fail -
we catch it. If something else goes wrong - we want to fail and not hide ;p
The DB does not exist on the first use of Browse. Actually, it does
not get created until the first website sets the first cookie, AFAICS.
That means that on the first use of Browse the user goes to the XS and
doesn't get autenticated. So if the DB doesn't exist, _we want to
create it_. It's not a failure, it's success.
Ok, sounds good.
- the method could even be a function as it does not interact at all with
the class itself, not sure what is nicer
I'd prefer a function, but it's not my codebase, so follow the style... :-)
Done.
BTW: Is there a spec you used for the cookie format? I find field
descriptions like expires - you name it expiry.

Re: etextRead activity and espeak
Tony, I have some good news on TTS with Read Etexts. It turns out that speech-dispatcher is available through yum update, and it does work on the XO. If you follow the instructions at http://wiki.laptop.org/go/Read_Etexts#Using_Text_to_Speech you should be able to get Read Etexts to do TTS with working highlighting. Now the bad news: 1). You're going to have to adjust the Rate using the Speech toolbar tab down so that highlighting can keep up with speech. 2). Read Etexts does not pause between paragraphs and may not pause between sentences. I *really* need to fix this. 3). My test environment for developing Read Etexts does not have TTS working properly yet. It worked when I was using Xubuntu, but I cleared that off and replaced it with Fedora 10, which unlike the XO uses pulse audio. You can configure speech-dispatcher to use pulse-audio, and it will seem to work, but not for long. That's been my experience so far, anyway. Without a robust TTS test environment I'm not going to be able to improve on what I have for awhile. I haven't given up yet. 4). You need to start the speech-dispatcher service using the Terminal before you can use TTS. I know damned well that there is a way to start this when the XO boots up, but I don't know how to do it. Perhaps one of the others on the mailing list can suggest something. My wife is impressed that kids in Nepal might be using an Activity I wrote, and after seeing my demo of it she agreed the kids deserved better. So she may tolerate more hours of basement hacking than she normally does. I hope you'll try out Read Etexts with speech-dispatcher installed and let me know what you think.

I was lead to believe a few months ago that two instances of Sugar on the same network would find each other and be able to share even without a jabber server between them. I couldn't get that to work then and it doesn't work now. In any case, I have two machines running Fedora 10 and I want them to be able to collaborate.

I've started a long term measurement test using the ACR guage inside the battery. I'll check it on Monday. Based on a long term (44 hour) test I've measured that the average draw of the XO when powered off is 1.64 mA. Although this seems to match my previous measurement it actually does not. This is a measurement of the battery voltage rail. So 1.64 mA * 6.68V = 11mW. I was expecting a number half of that. The previous measurement was on the suspend 3.3V rail which would be 5.3mW so there's 5.7mW unaccounted for.

This is the problem with your understanding. A shared activity is _initiated_ by one user, but this user does not _own_ the shared activity. The user who initially shared the activity can turn off his computer, and the other users can still continue to share with each other. You can see this with the Chat activity, for example. Sharing can only continue without the initiator if the sharing code for a specific activity supports it. If you are writing an activity, you must figure out how to handle the case where the initiator leaves. If you cannot support continued sharing after that point, then you may wish to notify the user that the instance is no longer shared. However, it is better to design your networking code so that sharing can continue. - --Ben -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.9 (GNU/Linux) iEYEARECAAYFAkmZ3rYACgkQUJT6e6HFtqTrxQCfRyxdcBovZMnozHecOu32jIph 28IAn0L6e3332NVba4oFJgg4/vHHdzl1 =mt9d -END PGP SIGNATURE- ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

One could try adding wlan-reset to /boot/olpc.fth, thus ensuring that the wireless module is not carrying over any state from the firmware. In the normal case of booting from NAND (or USB or SD), OFW doesn't even turn on the wireless module. This is easy to confirm - just observe that the wireless led doesn't turn on until well into the OS startup. I'm quite sure that the OS wireless code doesn't extract the wireless firmware image from OFW - it could in theory do so, but I'm sure that it doesn't - it gets it from the filesystem. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

The user who initially shared the activity can turn off his computer, and the other users can still continue to share with each other. You can see this with the Chat activity, for example. I'm missing a key idea. Some activities have persistent data, say a document. Another example would be the high score database for a game. That data has to live somewhere and/or somebody has to own it. You can put it on a server, or one of the users can act as the server, perhaps the one who initiates the shared activity. I think another example that was discussed recently was viewing a batch of slides. One proposal was that the other users only loaded the page they were interested in. I think that leaves the initiating user acting as the server. Are there two types of sharing, one with persistent data and another without? -- These are my opinions, not necessarily my employer's.

You can modify the text in /etc/init.d/diskspace{check,recover}.
It is not localized past English and Spanish, because it runs before
almost anything else on the system.
I think you might end up finding that it runs before the Unicode
environment has started, which would stop you from printing Nepali.
(You can move it later in the boot sequence to work around this,
but as you do so you're increasing the chance that something else
will break due to no disk space before the script gets to run.)

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hal Murray wrote: This is the problem with your understanding. A shared activity is _initiated_ by one user, but this user does not _own_ the shared activity. The user who initially shared the activity can turn off his computer, and the other users can still continue to share with each other. You can see this with the Chat activity, for example. I'm missing a key idea. Some activities have persistent data, say a document. Another example would be the high score database for a game. I'm not sure what you mean by persistent, but I believe I understand your overall point. Many activity implementations work internally by designating one of the participants as a super-node or server, and then using that machine as a central point for maintaining canonical copies of data and synchronizing communications. A good example of a current Activity written in this way is Write, in which the main copy of the document is kept on the server, which is also the machine on which the instance was initiated. In the current Sugar design, an Activity like Write that behaves in this way is considered broken. That is, the Sugar UI presents an abstraction in which all nodes of an Activity are equal, and in principle sharing continues regardless of who leaves. This is deliberate, because that's the desired behavior. Sugar was designed with an eye toward sharing on a mesh network, where all network links are unreliable, and sharing must degrade minimally in the face of connection failures. In the case of Write, the authors are attempting to reach this point by writing code to elect a new super-node if the current one leaves the shared session. I believe that code has not yet been released. The last time I checked, if the initiator of a Write session left the shared session, the remaining users would still be nominally sharing according to Sugar, but no data would actually be transferred between them. It's possible that Sugar should grow some UI to indicate if a single group member is a keystone, and sharing will break if the connection to that user drops. That is, however, a fairly ugly thing to try to communicate to a user, and given a choice we would rather make it unnecessary. Personally, I've been working on writing a communications library called Groupthink that ensures that all state is correctly replicated across all activity instances. Any Activity that can be written using Groupthink will automatically be immune to the loss of any single member. - --Ben -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.9 (GNU/Linux) iEYEARECAAYFAkmaQuoACgkQUJT6e6HFtqTcjQCePlhnRJiX7uI7eeQPZTG7Ih5w 0BUAn0+f1YQNHI0yQ/PBDTPb2TX+dgjp =Lk5L -END PGP SIGNATURE- ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
