Wrong. Gadget is primarily intended to reduce the bandwidth consumed by Gabble under the load generated by Sugar. >So what does gadget do? Think of it as a server-side keyword search engine which you can query for lists of matching people and activities. The purported bandwidth reduction comes from sending each client only what it asks for instead of everything, which is what the shared roster hack does. >Is there a new client side UI for electing groups? Who chooses, the kids or >the teachers? etc. Guillaume filed https://dev.laptop.org/ticket/7711 eight months ago but the absence of comments in that ticket and the current paucity of results in http://dev.sugarlabs.org/search?q=gadget suggests to me that the Sugar folks have completely ignored the necessary UI work in favor of more pressing issues. Regards, Michael --------------------------- To understand how Gadget works, read http://wiki.laptop.org/go/XMPP_Component_Protocol and skim the contents of http://dev.laptop.org/git/projects/gadget/tree/gadget paying particular attention to the automated tests. Then, if you're feeling brave, read the Gabble source code: http://git.collabora.co.uk/?p=telepathy-gabble.git;a=tree;hb=master paying particular attention to the files whose names contain 'olpc'. _______________________________________________ Server-devel mailing list Serverfirstname.lastname@example.org http://lists.laptop.org/listinfo/server-devel
