Containers, Now and Then

Posted on July 1, 2016

I'm excited to announce that Cuddletech is now 100% Docker Powered. This is particularly exciting for me because it comes after being hosted on containers for the previous 10 years of its life. To celebrate it seems like a good time to reflect on how containers have evolved over the last decade. For those not familiar with Cuddletech, since 1999 it has been my personal website dedicated to all things Solaris (and Enlightenment, and my ...

Welcome to the Age of E-Operations Management

Posted on November 12, 2015

DevOps has often been criticized for drawing too strongly from manufacturing metaphors.  SRE, DevOps, NoOps, we quibble over words.   What is DevOps?  We scratch at definitions to explain it.  I think the time has come for the confusion to end and for us all to accept the reality: we have entered a new age, the information age.  e-Commerce, e-Government, everything has changed as we've evolved with the coming of the internet.  We ...

What exactly is value?

Posted on May 12, 2014

In the LEAN and DevOps worlds we're obsessed with the idea of providing value. But what is value really? Some times we use a word so much that it is drained of any practical meaning and becomes more of an abstract idea. It may not be too much of a stretch to say that the word "value" ceases to really contain any value. Webster defines "value" as: "a fair return or equivalent in goods, services, or money for something exchanged" "the ...

Reflections on 25 Years of LEAN

Posted on March 17, 2014

Gemba Academy has posted an extremely interesting series of videos entitled: Reflections on 25 Years of LEAN.

SmartOS & Vagrant

Posted on August 7, 2013

There are many challenges associated with building applications in the cloud. One of the most challenging is that the cloud properly exploited is inherently transient. This means that your development environment must also be transient, such that you never depend on unfounded assumptions. Once upon a time you would routinely re-install your OS to ensure you weren't mistakenly assuming something were present. Moving development to a VM with a ...

Why SysAdmin’s Can’t Code

Posted on May 12, 2013

Most systems administrators are quick, perhaps too quick, to tell you "I'm not a coder."  Oddly, this admission normally comes after boasting about how many programming languages they know or have used.  Why is this?  Can this be changed?  Here is my 5 step plan on how any SA can become an honest to goodness programmer. Step 1: Find a problem you care about solving, for yourself SysAdmin's don't actually use tools, they study them. ...

Big Data is the hotness, there is no doubt about it.  Every year its just gotten bigger and bigger and shows no sign of slowing.  There is a lot out there about big data, but despite the hype, there isn't a lot of good technical content for those who want to get started.  The lack of technical how-to info is made worse by the fact that many Hadoop projects have moved their documentation around over time and Google searches commonly point to ...

Writing a Better SOP

Posted on September 25, 2012

Within an ops team you should have 3 primary types of governance enablers: controls, policies and processes. A control is a guiding principle, which is implemented as a one or more policies (which are just rules), which are in turn standardized in a set of procedures. Its important to have all 3, because controls are very vague, policies are often general and broad in nature, which means to provide consistent quality results we require ...

DevOps LA on Aug 27th

Posted on August 18, 2012

I've been invited to speak at  DevOps LA on Monday, Aug 27th.  The title I've chosen is "The DevOps Transformation" but it will not be the talk I gave at LISA. Partly because I've already given that talk, and partly because I only have a 20-30 minute speaking slot.  I'll be looking beyond those fundamental principles and considering some new material, including work flow, routing, and conversion with the LEAN world at large.  I will not ...

Konsidering Kanban

Posted on June 4, 2012

Kanban has become an increasingly popular "agile" technique which is consider as similar to Scrum and Extreme Programming.  David Anderson created the agile form of Kanban from his experience in Japan.  In his book he tells the story of his visit to the Imperial Palace Gardens where there is no admission cost, but the flow of visitors is constrained by a stack of kanban (cards), people can enter until the kanban are exhausted, then as people ...
