[LEGAL-303] ASF, RocksDB, and Facebook's BSD+patent grant licensing
Facebook's licensing includes a "nuclear option" if a user acts in a way interpreted by Facebook as competing with them; the ASF has marked the license as "Category-X", and may not be included in Apache projects as a result. Looks like RocksDB are going to relicense as dual GPLv2/ASL2 to clear this up, but React.js has not shown any plans to do so yet

FelixGV/tehuti
Felix says:

'Like I said, I'd like to move it to a more general / non-personal repo in the future, but haven't had the time yet. Anyway, you can still browse the code there for now. It is not a big code base so not that hard to wrap one's mind around it.

It is Apache licensed and both Kafka and Voldemort are using it so I would say it is pretty self-contained (although Kafka has not moved to Tehuti proper, it is essentially the same code they're using, minus a few small fixes missing that we added).

Tehuti is a bit lower level than CodaHale (i.e.: you need to choose exactly which stats you want to measure and the boundaries of your histograms), but this is the type of stuff you would build a wrapper for and then re-use within your code base. For example: the Voldemort RequestCounter class.'

Haywire
kellabyte's hack in progress -- 'an asynchronous HTTP server framework written in C. The goal of Haywire is to learn how to create a server with a minimal feature set that can handle a high rate of requests and connections with as low of latency and resource usage as possible. Haywire uses the event loop based libuv platform layer that node.js is built on top of (also written in C). libuv abstracts IOCP on Windows and epoll/kqueue/event ports/etc. on Unix systems to provide efficient asynchronous I/O on all supported platforms.'

Outperforms libevent handily, it seems. Apache-licensed.

fauxflake
an easily embeddable, decentralized, k-ordered unique ID generator. It can use the same encoded ID format as Twitter's Snowflake or Boundary's Flake implementations as well as any other customized encoding without too much effort. The fauxflake-core module has no external dependencies and is meant to be about as light as possible while still delivering useful functionality. Essentially, if you want to be able to generate a unique identifier across your infrastructure with reasonable assurances about collisions, then you might find this useful.


From the same guy as the excellent Guava Retrier library; java, ASL2-licensed open source.
