The language selection specific should be fixed by Tails >= 0.11 (no language menu anymore in bootloader), the "Debian Live" confusing message is fixed in Tails >= 0.12 (custom Tails syslinux menu). > # Second issue: wifi and tor browser > The tor browser starts up before the wireless is configured. > The tor browser then reports a proxy error.

I'm a bit surprised, since a notification about the time being sync'd, and this operation being necessary for Tor to work properly, should be displayed quite early since Tails 0.10.1. > 8 of 8 waited patiently for something to happen on the screen.

Hmm... they were asked "to browse to their favorite site", and did not do anything once they were presented a web browser? I'm at a loss...

OK, this clarifies. So, this is a problem of our iceweasel not looking enough like "a" web browser, apparently. Oops. Probably check.tpo should be rephrased (s/your/this/, to start with) so that it's clearer That Thing is the web browser that's configured to use Tor. > 0 of 8 understood what the IP address message meant.

Another one I am very fond of is ZeroMQ, but I think we should not start worrying about supporting such advanced and scalable libraries at this time. This is the reason why I stated at the beginning of the requirements that we should "so we will look at it as if it were running only on one central machine". The scalability issues will be dealt with once we have properly defined the problem scope. Making the node communication rely on Zero(C|MQ) can be something that we integrate without having to require clients to change their behavior. I think the overall feeling from the responses is that going for something like an HTTP RESTful API is what we are looking for. HTTP is a well understood technology and I have quite some experience in designing and building RESTful APIs based on twisted (cyclone) and this is also what is used in other [1] projects [2] belonging [3] to the [4] Tor community [5]. Moreover by looking at how the reporting systems of other network measurements tools worked [5] we found that almost all of them used an HTTP API to collect reports [6][7][8][9]. I see this as an indication that such a strategy is the best practice. For the time being we should go for something simple like this and once we encounter major scalability/performance bottlenecks we can quantify them and figure out what the best path to a solution may be. If you were the developer of a censorship detection tool would you like to have to report to anything that is not a RESTful HTTPs API? - Art.

Oh, that would be very useful. Maybe we can come up with a template for all Tor tech reports. > Some of > the graphs are also very hard to read (dashed lines don't work very > well for plots that jump up and down a lot). Right. There's always the trade-off between using colored graphs which don't go well when printed and dashed/dotted lines which are at least equally useful on screen and on paper. I'm open to suggestions there. (Note that the graph sources are in a different Git repository than the LaTeX sources.) > I see that there is a git repository for the sources, can I just clone > it, make changes, and put the diffs somewhere? What would be most > convenient for you? I just committed the LaTeX sources of these reports very quickly to my new public tech-reports repository: https://gitweb.torproject.org/user/karsten/tech-reports.git If you can clone the branch and put yours somewhere from where I can pull, that would work best. git format-patch also works fine. Once reports are ready for "publication", I'll merge things into the official tech-reports.git repo. Thanks!

[tor-dev] [GSoC] Vidalia Report - Week 8
Last fortnight, I had got the add, remove and edit Hidden Service functionality working. I have been working on fixing a few UI issues - sizing, input sanity check and a browse button for selecting directory. I'm beginning work on the bandwidth scheduling plugin. I've been trying out the ways of doing it through relaybandwidthrate and will be starting on the UI.

If you are packaging/using Twisted, then yes, Ice is redundant (unless someone planned to differentiate "signaling" from "data" protocol, for example). >> It can optionally use TLS, interface definition for RPC and structures >> is written only once (each language binding then loads it and maps it to >> native object of its own as "usual" method calls or attributes). > >> Advanced features include asynchronous calls, at-most-once semantics (it >> can retry RPC call for methods that are marked "idempotent", i.e. whose >> multiple invocation is same as one invocation), persistence via Ice >> Freeze (might work for the file storage, not sure how big are your files, >> internally it's implemented on top of BerkeleyDB), forward/backward >> compatibility among versions of your API (up to a limit)... > > Becoming more convinced.

Unfortunately, there's no fallback in Ice for that (its firewall-evading also uses SSL/TLS which is not useful here). Maybe I misunderstood Arturo's requirement that said TLS or TorHS was considered for encrypted/authenticated transport.
