I'm a statistic also. Moved back to Austin, Texas where quality of life is much better and people are laid back.

Twitter open sourced Zipkin, their distributed tracing system based on the Dapper paper: http://twitter.github.com/zipkin/

To this date, one of my favorite sites out there is the Lotus Notes sucks site: http://lotusnotessucks.4t.com/

Love the error messages: http://lotusnotessucks.4t.com/lnEx70.html

Have they heard of Bitbucket? Gitoroius?

Gitblit? http://gitblit.com/

I think open source has changed a bit with the rise of the GitHub era. IMHO, I think @mikeal did a good post regarding this change "Apache considered harmful" http://www.mikealrogers.com/posts/apache-considered-harmful....

Even in the old days, it's easier to fork than work with upstream. I think these days it's just easier share those forks with services like GitHub. It should help spread ideas and improved solutions IMHO so downstream consumers actually benefit.

In Twitter's case, they are planning to do what works for them at the moment: "While we initially focused on the challenging goal of making Memcached work extremely well within the Twitter infrastructure, we look forward to sharing our code and ideas with the Memcached community in the long term."

Just to clarify things since I helped write the initial blog post about twemcache... in our original post, we had an error regarding the slab calcification problem we mentioned, this problem ONLY applied to our v1.4.4 fork of memcached. After speaking with the upstream maintainers, we learned that recent memcached versions have addressed some of these problems. These are the type of conversations we want to have.

At the time we adopted memcached, that's the version we went with and made sure it worked well in our production environment as we scaled as a company. We also open sourced twemproxy [https://github.com/twitter/twemproxy] which is a lightweight proxy for memcached which has worked well for us in combination with twemcache and may work well for others too.

We just want to reiterate that twemcache has worked well for our unique environment and any teams evaluating memcached should try all their try all their options, just like any other piece of software you adopt in your stack.

One of the reasons of open sourcing our work was to share our ideas with the memcached community to see what worked well for us and help everyone. For example, this is also how we treat our work with our MySQL fork [https://github.com/twitter/mysql] which we maintain in the open and have signed an OCA with Oracle to help get work pushed upstream so everyone benefits in the long run.

They also announced twemproxy (a fast, light-weight proxy for memcached) which was quietly open sourced before: https://github.com/twitter/twemproxy

It's mostly semantic versioning under the covers: http://semver.org/

Here's the official announcement from Twitter Engineering:

Nice, Austin is a great city.

It's a utility gem that helps power the Twitter Translation Center: http://translate.twttr.com/

It may not be for everyone but hopefully some people may find it useful.

At the moment it only supports Apache Pig.

It's also on Github for comment: https://github.com/twitter/innovators-patent-agreement

There's some of us who work on JGit (http://eclipse.org/jgit/) which is used by many folks to get cross-platform Git support. The .NET community took things a step further by cross-compiling to C# via NGit (https://github.com/mono/ngit) to get solid Git support.

Stepping back, it's a bit crazy to see these two different communities working together :)

Please note that this is a demo (outdated too) and not really authorized by the project itself. It's unfortunate that some folks feel a need to put something up so quickly.

If you want to look at the current status of 2.0 and help test the release, please look at the 2.0-wip branch: https://github.com/twitter/bootstrap/tree/2.0-wip

The team expects to release something in a few weeks.

You look at this presentation which talks about JGit at Google, if you skip the first few slides...

https://docs.google.com/present/edit?id=0ATM14GNiXaXfZGZkeHp...

This is an old email... there's been many improvements to both JGit, Java/JVM and other areas of interest.

Shawn and I gave a presentation at the Googleplex not so long ago about JGit [1]. In particular, you may be interested in the 'JGit at Google' section.

There are some cases where JGit is faster than CGit, but the benefits of JGit are that it's easy to embed. There are projects like gitblit and other IDEs that use the library. On top of that, you have crazy folks like NGit [2] who cross compile the library using Sharpen so it can be used by the .NET community...
