Talk about people as alumni not as ex-employees. That's a cultural choice you can make. - @jenniferdary — Chris Coyier (@chriscoyier) May 2, 2014 This tweet (and thanks to Chris Coyier for tweeting this line from Jennifer Dary’s talk at Convergese 2014) really hits home for me. There are lots of reasons people leave companies. Not all of them are bad. Some of them have to do with the company and some of them have to do with the individual.

I type a lot of Docker commands every day. As a result I’ve made a habit of creating Bash functions and aliases that I find useful and adding them to my .bash_profile.1 Getting the IP address My first useful alias, dip, is a short-cut to the docker inspect command that allows you to inspect a container. One of the command’s features is using the --format flag to select a subset of the inspection data.

I am pleased to announce that The Logstash Book has been extensively updated to reflect the changes in the Logstash 1.4.0 release. There is a lot of new content, deprecations and updates to reflect the changes in Logstash including new installation methods, changes to the configuration language and a variety of plugins. It also includes a bunch of updates from awesome folks who have submitted errata and pointed out issues. Please keep this up - it really helps me!

Creating a Docker Dockerfile to build an application is pretty easy. But what if you already have a large collection of Puppet modules (or Chef cookbooks) that you want to use to build your applications? We’re going to see how easy it is to make use of those modules inside a Dockerfile.1 We’re first going to build a image that has Docker apps with Puppet installed. We’ll also add Tim Sharpe’s very cool Librarian-Puppet to the image.

Some of you are aware that Venmo was recently acquired by PayPal. I decided after a lot of soul searching that this wasn’t a move I was interested in making. Sadly as a result I am moving on from my role as VP of Engineering at Venmo. At the same time I’ve been talking to the team at Docker Inc about their roadmap and plans as part of my work on The Docker Book.
