Technical Liabilities and not Technical Debt

My last – frustrated – post finished with this line: “banks are collecting technical debt the way they used to collect sub-prime” I’ve always disliked the tech debt metaphor, in part because the way it is generally used is different to Ward Cunningham original defined technical debt and in part because those using it often have a simplistic understanding of ...

Kubernetes: Spinning up a Neo4j 3.1 Causal Cluster

A couple of weeks ago I wrote a blog post explaining how I’d created a Neo4j causal cluster using docker containers directly and for my next pet project I wanted to use Kubernetes as an orchestration layer so that I could declaratively change the number of servers in my cluster. I’d never used Kubernetes before but I saw a presentation ...

Extending a LVM based file system

A file system running out of space doesn’t always have to be a major catastrophe. The problem could be quite easily resolved, if you happen to be running Linux and were foresighted enough to create your file system on a LVM volume. If you also happen to have extra storage space available, the file system could likely be extended in a ...

Evidence-based principles

A previous post tried to find objective correlations1, 2 between the number of times a method was updated and its structural properties. Given that the probability of a method’s being updated during a project’s lifetime depends entirely on whether that method partakes in the features arbitrarily desired by customers, it might have been guessed that such end-user whimsy would completely ...

Bash on Windows 10

Because I work with Linux and Windows based machines for development, I often find myself wishing that I had some of the handy command-line Linux tools available in my Windows environments. Cygwin, PowerShell, and custom Groovy scripts written to emulate Linux tools have helped, but I was pleasantly surprised to recently learn that Bash on Ubuntu on Windows 10 is ...

Iterations and Increments

Agile is iterative and incremental development and frequent delivery with cultural change for transparency. What do the words iterative and incremental mean? Iterative means we take a one-piece-at-a-time for creating an entire feature. Iterative approaches manage the technical risk. We learn about the risk as we iterate through the entire feature set. Incremental means we deliver those pieces of value. Incremental approaches ...

Observers for AST nodes in JavaParser

We are getting closer to the first Release Candidate for JavaParser 3.0. One of the last features we added was support for observing changes to all nodes of the Abstract Syntax Tree. While I wrote the code for this feature I received precious feedback from Danny van Bruggen (a.k.a. Matozoid) and Cruz Maximilien. So I use “we” to refer to ...
