No. The current WoT code is neither flow-based nor particularly related to the Advogato algorithm. It's purely alchemical, having neither a proper specification as to the problem being solved nor any sort of theoretical basis to believe it solves that unspecified problem. Retrieving trust lists for large numbers of nodes should scale fairly well, as long as the updates can be slow. IMHO the only real problem presented is startup for a new user (downloading a few tens of MiB of scores might take a little while). Specifically, I don't think the scaling problem is any different or worse than the scaling problem inherent in trying to retrieve messages from that many users. And, whether it's a problem or not, there are *vastly* more important things to worry about than what to do once we have 1M users -- like how to get that many users in the first place. That sort of scaling problem gets put in the "nice problems to have" category in my book.

[freenet-dev] responses to WoT/search questions
have you joined the freenet-dev mailing list? in future i'd like to have these discussions there so that other people can see it too. (03:53:26) lusha: hi, can i ask a question about WOT? (03:55:33) evanbd: No need to ask permission :) (03:56:12) lusha: is there any document for this? (03:56:32) lusha: i dont quite understand how they evaluate trust (i think) WoT uses a flow-based metric similar to advogato (www.advogato.org) - see the source code (plugin-WoT-staging), or ask p0s on IRC (xor on the mailing list) for specific details. atm the implementation requires retrieving trust scores for everyone on the network, which won't scale in the long run. (03:56:48) lusha: is this for darknet? (03:56:57) evanbd: No. (03:57:05) evanbd: WoT is unrelated to core routing, etc. (03:57:24) evanbd: WoT is purely for evaluating the users of messaging apps for whether or not they're spammers. darknet works on connections between *nodes*, ie. running instances of freenet. WoT works on virtual identities - whenever you make a new SSK (read about this on the wiki), the priv/pub keypair you generate gives you a cryptographic identity, which you can use as a pseudonym, or "virtual identity". these work on independent layers; darknet is on the node layer, WoT is on the application layer. so, eg. if you have the right keypair, you can update that virtual identity from any freenet node. every action done using the same identity can be inferred to be from the same person, but you don't know which freenet node they're running. (03:58:00) lusha: it is related to search, indexing, right? (03:58:15) evanbd: At present, no. Eventually, yes. (03:58:36) evanbd: Well, depending... (03:58:48) lusha: i know...because one of the project is to make search compatible with wot (03:58:52) evanbd: It's for messaging apps, filesharing apps, and other things with users. (03:59:07) lusha: actually, not search...but the scalable indexing approach (03:59:18) lusha: i am just not quite understand wot (03:59:30) evanbd: Well, IMHO that has "make search work" and "make distributed indexing work" as prerequisites, but others might disagree. (03:59:39) evanbd: What don't you understand? at the moment, the keyword search system works on the application layer. freenet (fred) itself has no conception of content semantics (impossible anyway since everything is encrypted) X ___ Devl mailing list Devl@freenetproject.org http://osprey.vm.bytemark.co.uk/cgi-bin/mailman/listinfo/devl

We are not aiming for a workflow containing a push. What (I think) we want to utilize is the workflow that is used by e.g. the Linux team and the Git team, where only a few persons have access to the official repository, pulling changes from various other people that are doing the “hard work.” In that workflow fast-forward commits are actually preferable because they do not cause a merge and are thus less likely to cause conflicts and grieve. :) > X Bombe signature.asc Description: This is a digitally signed message part. ___ Devl mailing list Devl@freenetproject.org http://osprey.vm.bytemark.co.uk/cgi-bin/mailman/listinfo/devl
[freenet-dev] GSoC 2010 --- developing a firefox plugin
No need to apologize, thanks for the feedback! I took a look at the idea list, and I'm very interested in implementing at least one (if not several, time permitting) of the client improvement ideas. My top priority would be improving the web interface generally and helping to improve the content filters. That is, I'd make improving the web interface my main goal, and if I have time I'd like to help contribute to at least one or two content filters. I feel that a clean, streamlined, bug-free interface is one of the most important things to have when trying to get users interested in a piece of software and keep them interested. It's also something that I believe would be well within my ability to help implement while still presenting a challenge and helping to further my programming abilities. I also feel like it would be a great way to get my feet wet in the Freenet project, and perhaps after GSoC it would allow me to move on try to contribute to other various parts of the Freenet code. My first question is what kind of languages and APIs I would need to work with to improve the web interface. Also, I noticed a link to a wiki article on an "fproxy" mockup.

As xor said, if you have any questions about the details of a transport plugins project, just ask here, or on #freenet on freenode. There is no point in asking for "further information" without telling us what you already know; otherwise we would waste our time by telling you things you know already, and/or things you can't yet understand. If you are starting completely from scratch, have a read of the GSoC ideas page on the new wiki. Learn the basics of how freenet works, and the subtopics needed to implement a transport plugin. Also, build and install freenet and have a quick browse through the source code. Additionally, on top of the project proposal, we recommend that applicants contribute a bugfix or a minor feature, to demonstrate a good coding ability. X

What I meant by weird was it'll look like this: -o---o o---o <- master \ / \ / \ / -o---o---o---o---o <- identicon which looks like master was pulled into identicon then branched off again.

[freenet-dev] A microblogging and/or real-time chat system of GSOC
I suggest you think of it more like Twitter than IRC. I believe that Twitter is a more natural match to the sort of protocol you need to use over Freenet. So, when you say something, anyone who is following you can see it. So can anyone who searches for any hashtags you used. You seem to have some misconceptions about how Freenet works. Have you installed Freenet and started using it yet? I also highly recommend you read some of the papers about Freenet and look around the wiki a bit. And ask questions if it's not clear! In short, there are two operations that the network supports: insert and fetch. Insert takes some data, and a key that will refer to it, and sends the data out onto the network. It is passed from node to node, and routed toward nodes with a location dependent on the key. Nodes along the route keep a copy of it. Fetching is similar: the fetch request takes a key, and the request is routed toward nodes with nearby locations, until a node is found that has a copy of the data (because it was also part of the insert path, or part of a previous successful fetch path). The data is then sent back to the requester, and nodes along the path keep a copy. The data isn't stored on the inserter's computer; it's stored on other computers on the network. For a microblogging app, each post will be inserted into the network, and anyone following you will fetch your posts. If you go offline, it doesn't matter: your posts are already inserted into the network, and therefore available for anyone to fetch. If your followers go offline, then they can just fetch your posts when they return. And you're right that p2p makes messaging somewhat awkward. But, if there's a central server, then you're dependent on them. If they decide to censor you, there's nothing you can do. So, I don't see an alternative that would meet Freenet's goals. However, I don't think it's as awkward as seem to think: the insert and fetch operations provided by Freenet, while somewhat awkward to use, are actually very powerful. Having the data persist in the cloud (mostly) independent of which computers are online is quite powerful. I'm not terribly familiar with UI technologies, so I can't say what's a good or bad idea for that, really. You should plan to have your program be a plugin for fred; I suggest you take a look at other plugins to get an idea for what that means.

[freenet-dev] A microblogging and/or real-time chat system of GSOC
Hi, Thank you for telling me so many things about the microblogging. I do not really sure whether I have understand all the things. I think what you mean is that the system is similar as chat room. If I input something, everyone who is my friend should see the comment and I can also chat with some one I want to. If I understand it correct, I think use JAVA RMI or Web Service may be a easy way to complete it. But I have three questions. First, if I need to embedd this system into the Freenet, I think it is very different as web application. I should use Swing instead of JSP, JSTL and CSS to complete the UI. Second, as it is a whole P2P system, it will work well when everyone is on line. But if I am off line, others cannot receive my provious comments. Third, if my friend off line, do I need to store my comments in my computer and send it when they on line? All the question is around the P2P method because I have no server to store the messages. I think P2P is not a good way to do message publish and menegement. Can you provide some hint about how to deal with these problem. Thank you for helping me.

What database you use? (I have MySQL and Oracle 10g > experience)? I'll let someone else speak to the gsoc issues; here's a brief summary of the technical problems. The first thing to realize about any sort of microblogging or chat application on Freenet is that it will be *very* different from a normal web app on the back end. (The UI end can and should be as similar as possible, though.) First, there is no central server to talk to. It's *completely* peer to peer. Second, there's a spam problem: globally writable namespaces don't work. And third, the raw operations Freenet provides (insert and fetch, but not update or directory listing equivalents) are somewhat awkward to work with. The combination of these is why I thought microblogging might be a better model than IRC for real time communication over Freenet. Each user publishes messages in an outbox, and polls the outboxes of users they wish to follow. That, a UI, and integration into the web of trust plugin (to provide a list of other non-spammer users) can provide the very basics of microblogging. After that, the important optimizations include ways to discover new messages faster than polling everything, and ways to search hashtags and usernames and such efficiently. That's where things get both interesting and hard. Freenet latency is high: expect 5-10 seconds one way, with modest changes to Freenet. Even though you could build either chat or microblogging on the same underlying framework, calling it microblogging does a better job of setting user expectations. I put some thought into what the protocol should look like with a goal of optimizing speed and searchability. I wrote some test code, but nothing of any significance. You can find my thoughts on the protocol on Freenet: freenet:u...@cf9ctasza8w2jafeqmiln49tfrpdz2q5m68m1m5r9w0 ,NQiPGX7tNcaXVRXljGJnFlKhnf0eozNQsb~NwmBAJ4k,AQACAAE/Fritter-site/2/ When writing a gsoc proposal, give some thought to what parts of the problem you want to tackle. It sounds like your experience and interests lie more in the direction of user interfaces. If that's correct, my suggestion would be to make that the focus of your proposal. For example, you could ignore the problems of protocol design (by using my proposal, for example -- I'm sure it could be improved, but it's probably good enough) and searching (by simply not implementing any). IMHO a well-written, easy to use interface is more important than hard features like search. Search support could be added later, once it has users.

As xor said, if you have any questions about the details of a transport plugins project, just ask here, or on #freenet on freenode. There is no point in asking for "further information" without telling us what you already know; otherwise we would waste our time by telling you things you know already, and/or things you can't yet understand. If you are starting completely from scratch, have a read of the GSoC ideas page on the new wiki. Learn the basics of how freenet works, and the subtopics needed to implement a transport plugin. Also, build and install freenet and have a quick browse through the source code. Additionally, on top of the project proposal, we recommend that applicants contribute a bugfix or a minor feature, to demonstrate a good coding ability.

What I meant by weird was it'll look like this: -o---o o---o <- master \ / \ / \ / -o---o---o---o---o <- identicon which looks like master was pulled into identicon then branched off again. Which is basically what has happened here without --no-ff. But it should really look like this: -o---o---o---o---o <- master / / / -o---o---o---o <- identicon If you are going to have a merge-and-push workflow then it makes sense to do this consistently, and generate a merge commit whenever you pull from a repo that you are not tracking.

[freenet-dev] git tree weirdness in WoT

I thought I had:
- used "git fetch git://bombe-repository-uri identicon" to get bombe's
identicon branch
- used "git merge identicon" to merge it to master
- used git fetch to get saces' branch (called saces aswell)
- used git cherrypick to cherrypick commits from saces' branch
My intention was to use the identicon branch directly from bombe instead of
importing it from saces own branch, for the sake of using it from where it
came from originally.
Unfortunately, this was my first complex git operation so it may very well be
screwed up
Can someone help us how to fix this? I don't know :(
And I would like to know how I should have done it because the same operations
have to be done for Freetalk... there are bombe and saces branches there
aswell...

No :(
Why does it? :(
