I thought it’d be interesting to compare how many people admit to knowing ancient programming languages on their LinkedIn pages. This is in a contrast to my post on the popularity of hip JVM languages Scala and Clojure.
Ever wondered what Devops would look like when it would be invented by Coca Cola? Enjoy my Ignite session from Devopsdays Paris 2013.
A reduction in DevOps tickets not only drives IT efficiency, but also creates a cultural shift where teams look forward to rapidly achieving accomplishments. Business stakeholders operate in an agile environment where no change request is too small, and rapidly testing business ideas is the new normal.
As I’ve mentioned in a couple of previous posts I’ve been playing around with creating a Vagrant VM that I can use for my neo4j hacking which has involved a lot of messing around with installing apt packages.
In an earlier post I described networking modes in VirtualBox. Combining those modes you'll get some kind of swiss knife in realizing somehow exotic networking modes in your VMs.
SmartSVN, the popular cross-platform client for Apache Subversion, provides all the tools you need to manage your SVN projects out of the box, including a comprehensive Revision Graph.
Understand how IO Block sizes play a major role in Performance of an Amazon EBS
A very short summary of what OSGi provides, and why using it pays out.
One thing that I miss in GitHub is the ability to get e-mail notifications on each push/commit. There is an option to set an e-mail notification address in the repository settings, but you can only specify a single, global address, and only the administrator can do it.
The performance of a block storage device is commonly measured and quoted in a unit called IOPS, short for Input/Output Operations per Second (IOPS).
This episode, we delve into the always-squishy “DevOps culture” and take a closer look at the process of both asking and answering questions.
Inversion Of Control is one of the most common and widely used techniques for handling class dependencies in software development and could easily be the most important practice in unit testing.
What challenges can DevOps address in current organization environments, and how can it provide benefits to business and IT users?
After a bit of research, I discovered that the secret is to put the umask statement in my .bashrc file before the line that says [ -z "$PS1" ] && return as when Capistrano logs into the server, it doesn't have an interactive shell (and so $PS1isn't set.
We’re just back from Heroku’s Add-on Provider Summit in London where we were getting the skinny on Heroku’s upcoming addon provider roadmap!
The numerous benefits of unit testing have been well documented and extensively written about but surveys conducted by Typemock show that in many cases, unit testing is dropped after the first negative experience despite their financial and professional value and before its benefits become apparent.
We’ve all seen it. The application breaks on a developer’s laptop. It’s fixed by a configuration change such as adding a data source or changing a threshold or toggling something.
While Continuous Delivery has a well-defined value proposition and a seminal bookon how to implement a deployment pipeline, there is a dearth of information on how to transform an organisation for Continuous Delivery.
I’ve been working on a tutorial around thinking through problems in graphs using my football graph and I wanted to deploy it on a local vagrant VM as a stepping stone to deploying it in a live environment.
JUnit's "Theories" runner is an (mostly) undocumented experimental runner that allows you to run your @Test method (your @Theory) against all possible combinations of parameters (your @Datapoints) you can throw at it.
This article shows a simple example, a common caveat with the default runner, and how you can write your own data supplier to get better control over the values passed to each parameter of your @Theory
Today: Scaling at Pinterest, Netflix pushes HTML5 video, a new CoffeeScript learning tool, and an international collaborative effort to solve software challenges in space and on Earth.
As far as I can tell the reason for this is that bitbucket hasn’t been verified as a host by the VM and therefore the equivalent of the following happens when it tries to clone the repository.
A simple but flexible solution for Project configuration with Spring.
User Stories are simple in construction but there are complex issues to be resolved in their application. In this article we look at some of the issues involved, such as the authoring of Acceptance Criteria, how to handle defects and tasks, and whether or not User Stories are appropriate for the capture of Non Functional Requirements.
The lightning talk I gave at PyCon is now online. I talked for 4½ minutes on Toro, the package I wrote to provide locks, events, conditions, semaphores, and queues for Tornado.
