The code I announced yesterday is now in the v60-plus-tweaks branch. The master branch (non-fast-forward) is now the Record git tree from activities.sugarlabs.org, with my v60 rework placed on top of it. i.e. working towards a patch series that can be applied to SL upstream. It's working fine but has a regression over v66 - v66 supports systems without Xv, this one does not. (not a release blocker, IMO, but might not be too much effort to add this again) Current plans of Record on http://git.sugarlabs.org/projects/record: Since there are window related glitches on metacity (0.86+) and coding gst on python level is fragile (if make this precess smooth i.e. w/o just reset everything on every mode switch) in such not trivial case like Record. I was planing to code current master as less as possible and switch to camerabin and new UI w/ gtk.Window less design. Unfortunately I found that camerabin (w/ some proposed to upstream patches) can smooth work on XO-1 only in 176x144 mode, but in such resolution camera view region is less then usual which makes this mode useless. So, since most of users have XO-1 (I suppose) and coding two phases vide encoding (one encoded vide + wav and wav encoding in second phase) sounds pretty uncommon in not XO-1 case (and also for camerabin upstream) I postponed new Record coding. If there is an intention to have dev.l.o branch on git.sl.o, I can add new user to commiters list to merge/reset master to dev.l.o code. In this case we just need someone who will maintain it and also git.sl.o code is targeting to not only XO users and maybe Xv less issue could be a problem for someone (but not sure that many people will be affected). -- Aleksey ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Where are you reading that displaylink requires a separate keyboard and mouse? libdlo supports the chip and the protocol not any specific device. While not immediately usefull overall I think this is a +1 since I've received several requests via the support gang list on how to make the USB VGA adapter work. Many have tried and seems everyone but the original has failed. USB projectors are listed as products that might be useful (if the have the currently spported chip or when other chips are added) All the the requests for a USB video were so they could hook it up to a projector for training classes. The possibility of USB projector support seems very worthwhile. If none of the projectors are supported yet then there's not much point in adding it to the build but if someone gets a projector working then we certainly should support it. -- Richard A.

I believe it is clunky to have children create their own networks..Who designates who creates the network? Why do I have to join that network? Why can't I make my own network and have them join me, etc.. All of this is aside from the technical limitations of which channel does my network get created on. Does the user specify channels 1, 6, or 11 when creating the network, or does the channel randomly get set? If randomly set, how do we avoid channel overlaps and interference. To ease all of this and maintain a similar UI, what if we: -Create three faux Mesh Channel # icons in the Network view -When the child wants to join a mesh network they will select one of the networks -Upon selection: the XO will: 1. Scan to see if that ad-hoc network already exists and 2. if it does not exist the XO will create the network allowing other children to join it. The one pitfall of this idea, and I'm not sure how much of an issue this would be, is also the pitfall of ad-hoc networks...when the initiator of the ad-hoc network leaves the network fails. When the network has a respective name it is a bit more obvious when that person has left and the reason why the network has failed, this would not be the case given the anonymity of a Mesh Network #. A more long term solution to this problem may be for the XO to sense the loss of the initiator and recreate the network. In this case, the first XO to sense the loss of the network after some period of time would check if another XO has already setup the network, if not the XO would create the network or join the new one if it already exists. Aside from the one pitfall, I think it would be really beneficial to maintain the same UI and appearance of functionality.

Re: Alternative to Create a new wireless network
* Do we agree to have three icons, one for each available channel? I have written this before -- I do NOT believe that three dumb icons are more intuitive to use than one intelligent icon. The only advantage to three icons is that a new network can be launched with a single click (after having navigated around to find *which* icon to click), whereas an intelligent single icon requires two actions - a hover to call out the palette, then a click on an entry within that palette. To me, the greatest drawback to the existing icon(s) is that they do not show the channel. If you have three icons, for heaven's sake draw them with static symbols (1, 6, 11) to show where a connection would be attempted. If only a single icon is used, it should at all times show a dynamic symbol representing the channel to which the radio is currently tuned (a different channel would be selected via the palette). I think that even very young children would quickly learn which channel to use in which physical location. I fail to see how presenting three icons (which are indistinguishable from each other) helps communication. I vote for one, intelligent, icon. mikus ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: Hulahop browser screen width XO1.0 vs XO1.5
No, I don't think it is a widget, gtk problem -- since I could change the
CSS to correct the problem.
I wrote a javascript fragment:
document.write('width:' + window.screen.width + height: +
window.screen.height);
On XO1.0 I got a response: width:840 height:634 and on XO1.5 I got
width:1200 height:900
If this is a known situation, and it is desired for some good reason, I'm
sure people like me can live with it. Otherwise I think the rendering
engine on 1.0 and 1.5 should come up with similar defaults -- and
considering our installed base-- it should be compatible 800x600.
Persuant to Seth's suggestion, I've discovered that it is possible to write
CSS using percentages rather than absolute pixel dimensions, and circumvent
haveing to make a decision in javascript based upon reported screen
dimension, and load separate CSS pages.
Somebody has cleaned up the webview widget. I'm having to work around a
problem in build 802 that is fixed in F11 -- In the earlier build the widget
controled it's own visibility by doing 'self.web_view.get_toplevel().hide()'
which made it much more difficult to incorporate in at activity that wanted
to use other widgets as well.

The icons should look the same on all laptops, and should not look at all like the XO-1 mesh icons. * Naming: do we agree to name the networks 'Mesh Network [channel name]' even though they are no mesh networks but in order to keep 'backwards compatibility'? No. I'd prefer we lose the word Mesh for these icons. I suggest the word Our or My instead of Mesh. * I do not save the connection to the nm-config file and don't mark them to autoconnect, so we do not autoconnect when starting Sugar. I think, as an ad-hoc network is not a persistent configuration this makes sense. Yes, certainly. * Should we add an icon for 'mesh-network-connected' to better represent the mesh network we are currently connected to? I don't understand this question, sorry. Oh, maybe you mean that the icons should indicate connection status. Yes! In the same way that access point icons are changed; parentheses either side. * Connection sharing: So far the connections created are 'link-local' connections. What is the plan for sharing an internet connection over an adhoc network? As the XO has only one network device, i guess this is not a common scenario. No opinion. * Remove the 'Create Network' ability of the wireless frame device palette: As we have the default ad-hoc networks we may not need the ability to create adhoc networks anymore. It may be more confusing then of any help, what do others think? Yes, remove it. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

This does not happen on the XO1 802 build. Bug? Feature. A six-year old child called me on the phone a few days ago to get this fixed. I'd lent him an XO-1.5 to play with, but had neglected necessary training. Check that you haven't restarted a journal entry by accident. It's easy to do ... look at the activity ring, and if the Physics icon is monochrome then clicking it will start a new empty instance. If the icon is your XO colours, then it means that clicking it will resume the top journal entry saved by that activity. You may also right-click on the activity ring icon and select the monochrome Start entry in the menu. Or, in Blueberry alone, I think you can use Alt or some other keyboard modifier.

[Server-devel] make-server-delegations output and importing to XS
Hi Martin, We're working on the antitheft stage where the private signing server generates delegations and sends them to the internet-accessible antitheft server. We can work with the scripts that are already in bios-crypto but we're a bit confused by their design. Perhaps we are missing something, or maybe we're just encountering a disconnect being the first project to be doing this. The make-server-delegations script handles all laptops for all schools, but is written in a model where all output data goes in 1 directory, separated by school, where the school name is embedded in the output filename. But the XS expects something quite different -- if you're putting these on USB, it expects one-directory-per-school (where directory name = school name), and within that directory it looks for very specific names (e.g. d-lease.sig) which do not embed the name of the school. And if you're going to be setting up an internet-based sync service instead of using USB, the same structure makes sense, since each school just rsyncs an entire directory and then passes it to xs-activation-import. While it's not hard to write a script to take the make-server-delegations output and put it in the form expected by the XS, we're wondering why this is necessary. Surely every deployment is going to need to do this. We're also a little unsure of the design -- it maintains 1 open file handle per school. Thats 400 here, or presumably thousands if we're talking a bigger deployment. I propose a different design: make-server-delegations works for 1 school, with 1 key, to produce a single file full of delegations. The input file is: SN1,UUID1 SN2,UUID2 and the output goes to stdout. (designed to be redirected to a file) That way, the user gets much more control over the output structure. Here, we'd run it one time for every school we want to process. Thinking on an ongoing basis, it also means that it's much easier to only generate delegations for the schools where the lists of laptops have changed. You can store md5sums of the one-file-per-school laptop lists and only re-run that school through the delegation generator if it has changed since yesterday. Thoughts?

Re: [Server-devel] make-server-delegations output and importing to XS
I propose a different design: Works for me as long as you also craft a script that handles the run from a whole CSV file. In other words, the main workflow starts with a single 3-field CSV file exported from an inventory system...

You can store md5sums of the one-file-per-school laptop lists and only re-run that school through the delegation generator if it has changed since yesterday. Yep, that'd be a nice optimisation. The base scripts pre-date my involvement, and have a horrible approach. I was in a rush and followed the style, which has ended up not so pretty. A rethink/rewrite is welcome now, before these become popular. I am also thinking of splitting them off into a olpc-bios-crypto-utils. Makes no sense to carry (and build!) the slow-moving bios-crypto stuff with our fast-moving glue scripts. Did the lib ever get packaged as libtomcrypt-audited as was discussed in fedora-devel? m -- mar...@laptop.org -- 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

Just curious though, whats the justification behind this? is there an existing project that runs in this way? The single file model just doesn't seem so scalable.
