Did you guys see this video?: http://vimeo.com/53261709 Github uses MessagePack for their internal RPC protocol.

This actually seems like a great use case, going to read later, but I immediately thought of MongoDB BSON format.

Now facing this issue... By using 'adjtimex' command, you can clear the problematic INS bit.

At first, you can confirm the status flag like this.

    $ ./adjtimex --print | grep status
    status: 8209

8209's binary representation is like this. This surely have INS bit "100000000[1]0001" (5th LSB).

    $ ruby -e 'p 8209.to_s(2)'
    "10000000010001"

8193 is the value after the clearance of the INS big.

    $ ruby -e 'p 8193.to_s(2)'
    "10000000000001"

Then, let's set it as a current value. Please ensure your ntpd is not running.

    $ adjtimex --status 8193

fluentd's greatest advantage is, it's written in Ruby. So, it's really easy to write the plugin for any datastores.

This is HDFS (Hoop, the HDFS REST gateway) plugin.

And also, Cassandra plugin are now in under development.

You can see the user contributed plugin list here.

If you were going from logs -> hdfs, flume would be a much better chose imho

awesome slide!

Yep, we agree with your opinion CURRENTLY.

We're developing Hoop (REST API for HDFS) plugin, and also Stargate (REST API for HBase). It requires additional setup at the infra-side, but still very useful and performs well.

You can feed Twitter stream by writing in_twitter plugin. That will 30 lines of Ruby code :-)

This release includes transparent large page? This will hugely increase the performance of memory-consuming applications (c,f. Redis, HBase, MongoDB, etc.). I confirmed at RHEL6.

It's compiled from the same kernel source so it should have THP (I admit here that I've not verified this with CentOS 6). And yeah, THP is great.
