ideas for a modular database


we've had great success building modular database stuff on top of leveldb with node, but as I have learnt more about databases it's become apparent to me that the idea of a modular database would be better implemented at a slightly lower level.

Level db provides a sorted key:value store, which, because of the sorted property, many things can be implemented on top of. For example, for replication, or for consistent materialized views, we often need a write ahead log. This can easily be implemented via a batch write to level, and writing the log into a section of the leveldb key space which is treated as append only.

Response to Nodejitsu NPM Trademark

I've known people at nodejitsu for years, since before the company even existed. I still consider many of them friends. That said, somebody over there has lost their mind.

Trademarks are an important part of open source. They protect the integrity of the trust that is built by any project. A classic example of why this is the case is Firefox. Suppose that a malware producer takes the Firefox codebase, which is free and open source, packages up their malware with it and then releases it as "Firefox". Then they buy search advertising and suddenly their bad and malicious version of Firefox is the first result on search engines across the web. This is clearly a bad thing for Firefox and open source everywhere, but what can Mozilla do to protect their community of users?

They can't enforce a software license since the use is permitted under the Mozilla Public License. They can, however, enforce on these hypothetical bad actors using their trademark on the word "Fi
