A New Idea for Calling Functions

software-development-2-logo

Disclaimer: This is going to come off a bit ranty. I’m not as frustrated by the “problems” I bring us as it sounds; rather, it is used to emphasize why my thought processes did what it did. I’m not even going to be using header titles, which is weird for me :) I’ve had a recent thought process about calling ...

Common Agile objections

agile-logo

Last time (“Waterfall works when…”) I promised to discuss some of those common objections to “Agile.” (Actually, reading back this this post I’m struck by how like my “12 Myths of Agile Development” which was originally a blog post 2 years ago called “11 Agile Myths of 2 Truths”.) (Apologies by the way, “Waterfall works when…” was misposted the first ...

Waterfall works when…

agile-logo

I frequently find myself in situations where someone says something like: “Waterfall is appropriate when…” Some people out there think there are occasions when an Agile (mainly iterative) approach is “best’ and other occasions when “Waterfall” is “best”. Most of the time I let this line of argument go because its boring, I can’t be bothered arguing. (I’ll look at ...

Neo4j: Generating real time recommendations with Cypher

neo4j-logo

One of the most common uses of Neo4j is for building real time recommendation engines and a common theme is that they make use of lots of different bits of data to come up with an interesting recommendation. For example in this video Amanda shows how dating websites build real time recommendation engines by starting with social connections and then ...

Replanning your project with a time machine

software-development-2-logo

I have an amazing time machine that lets me think better about projects. This is part 1 in a series of blog posts exploring the use of a time machine. Let’s say that you have a project that has been running for a couple of months. Looking back at your issue tracker and other artifacts, you notice that it’s hard ...

InetAddressImpl#lookupAllHostAddr slow/hangs

java-logo

Since I upgraded to Yosemite I’ve noticed that attempts to resolve localhost on my home network have been taking ages (sometimes over a minute) so I thought I’d try and work out why. This is what my initial /etc/hosts file looked like based on the assumption that my machine’s hostname was teetotal: $ cat /etc/hosts ## # Host Database # ...

Aggregate Installation Tips

devops-logo

Aggregate Installation Tips One of the reasons I am writing this blog, is to keep “log” for myself on how I resolved issues. In this post I will describe how I installed several basic development tools on a Fedora OS. I want this laptop to be my workstation for out-of-work projects. Almost everything in this post can be found elsewhere ...

The Magic Setter Antipattern

java-logo

Setters and getter are evil. When the JavaBean definition was created it seemed to be a good idea. But they do a lot of harm to the Java community. Not as many as the null pointer generally, but enough. The very first thing is that many juniors believe that implementing setters and getter (hey, it is just a few click ...

Why Managers Ask for Estimates and What They Need to Know

agile-logo

In many of my transitioning to agile clients, the managers want to know when the project will be done. Or, they want to know how much the project will cost. (I have a new book about this, Predicting the Unpredictable: Pragmatic Approaches to Estimating Cost or Schedule.) Managers ask for estimates because they want to know something about their ability ...
