Introduction to Kafka

Kafka acts as a kind of write-ahead log (WAL) that records messages to a persistent store (disk) and allows subscribers to read and apply these changes to their own stores in a system appropriate time-frame.

Terminology:

Producers send messages to brokers
Consumers read messages from brokers
Messages are sent to a topic

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

My setup and configuration for Gmail/Google Apps

Making Gerrit and LDAP speak in tongues together via SSL

If you're an experienced Java developer or container/AS user, you'll probably want to just skip this, since it involves just some Java tools and standards techniques.
If you, however, like me, have only scratched the surface of the ceremony of the Java world (no troll intended), then you can probably find this useful, since I couldn't find proper documentation about this but had to assembly it together from various sources.

I started to configure a Gerrit instance on our company's server to start putting a bit of order in the mess that is our structure by now. Since the instance is private, I didn't want to enable OpenID authentication, nor I wanted to set it in development mode (aka everyone's invited). Having to choose between offloading authentication to an HTTP proxy and setting up an LDAP backend, I opted for the latter. Also, to complicate things further, I have not only enabled SSL support on the LDAP server, but I required _strict client c

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	configurations {
	apt
	}

	dependencies {
	compile 'com.squareup.dagger:dagger:1.1.0'
	apt 'com.squareup.dagger:dagger-compiler:1.1.0'
	}
