FeedTree 0.7.0 has been released to the wild. Shortly, it is a peer-to-peer network for distributing feed, RSS and Atom, to all subscribers instantly. In contrast, new feeds will be pushed to a set of subscribers and they will then push to other subscribers in tree fashion. Instead of developing full-featured feed reader for FeedTree, just a proxy, ftproxy, has been developed.

Technically, FeedTree relies on a peer-to-peer overlay network namely Pastry and Scribe protocol running on top of that. I don’t know much about Pastry. All I know is just it is implemented in Java. I don’t hate Java and I don’t like Java too. It is too big for me to run a Java application on my laptop just to read feed faster than ever.

According to the official AllPeers blog, the alpha version has been distributed to a handful of eponymous testers. The development team is actively testing issues relating to scalability. They also make a little promise to release private beta version in a matter of weeks. I would like to be a beta tester also.

AllPeers is a free extension which combines the strength of Firefox and the efficiency of BitTorrent to transform your favorite browser into a media sharing powerhouse.

Good luck, Google! I stand by you.

What is going on if all open source, low-level database engine owned by a big vendor? This is the time! We don’t need to think about that anymore. Last year, Oracle previously acquired InnoBase which is a part of MySQL for providing transactional process. As of today, Oracle has just acquired SleepyCat Software. That means Berkeley DB is now a property of Oracle. Who’s next? This action might change open source world. Even BTQueue, some parts of BTQueue rely on BDB.
