An Exploration of Symbiotic Design Practice workshop at NorDevCon from Michael Feathers

Feature Orthogonality and Health In Large Code Bases

Too often as software developers we take features as given – EE are there to give the customers whatever they want. The thing we neglect to realize is that feature choice impacts the longevity and maintainability of systems. In this keynote, Michael Feathers will explore this idea and describe now we can move toward a model where business weighs these impacts in the context of systems development.

Collection Pipeline Design Techniques

The resurgence of functional programming has had an odd manifestation in today’s technologies. Although we’re learning the value of immutability and starting to see that we don’t need class hierarchies to solve every problem, the type of code that we’re writing is actually stricter than what has been common in traditional functional programming languages. We’re using LINQ, Rx, Java Streams, and Ruby Enumerable to compose pipelines that transform data from stage to stage without access to any other state. This calls for a different design approach. In this session, Michael Feathers will outline strategies you can use to decide when and how to use this style.

Workshop: An Exploration of Symbiotic Design Practice

Decades ago, Melvin Conway coined what is now called Conway’s Law: “organizations which design systems … are constrained to produce designs which are copies of the communication structures of these organizations.” Conway’s Law is a deep insight but it is only the tip of the iceberg when we try to understand the interaction between organization and software. We fail to appreciate that we can use team structure, day to day process, and the interface between business and development as levers to affect the quality of design and code. With this perspective we can also see that concerns like technical debt and portfolio management lend themselves to new solutions when we understand software’s sensitivities upon its environment.

In this workshop, we’ll explore the intersection between software and organization through a series of group exercises and discuss ways of putting this understanding into practice.

Write Your Own Load Balancer: A worked Example

I was out walking with a techie friend of mine I’d not seen for a while and he asked me if I’d written anything recently. I hadn’t, other than an article on data sharing a few months before and I realised I was missing it. Well, not the writing itself, but the end result. In the last few weeks, another friend of mine, John Cricket , has been setting weekly code challenges via linkedin and his new website, https://codingchallenges.fyi/ . They were all quite interesting, but one in particular on writing load balancers appealed, so I thought I’d kill two birds with one stone and write up a worked example. You’ll find my worked example below. The challenge itself is italics and voice is that of John Crickets. The Coding Challenge https://codingchallenges.fyi/challenges/challenge-load-balancer/ Write Your Own Load Balancer This challenge is to build your own application layer load balancer. A load balancer sits in front of a group of servers and routes client requests across all of the serv...

Remember to Delegate: The Triangle of Trust

So you think you can lead a team? I’ve been talking and writing a lot about leading a software engineering team in 2025. I started thinking about it more deeply the year before when I decided to give a colleague, who was moving into team leading, some advice: 'Doing the work' isn't the only way to add value Remember to delegate Pick your battles Talk to your team every day Out of this came a talk, “So you think you can lead a team?” which I gave at work, at meetups and at conferences in various different formats during the first quarter of 2025. Here I am looking at Remember to Delegate and an idea which came out of discussion around the talk, The Triangle of Trust, in more detail. Delegate Delegation is a crucial skill for any team lead, yet it is often one of the most challenging aspects of leadership to master. Many leaders, particularly those who have risen through the ranks as individual contributors, struggle to let go of tasks, fearing a loss of control or a dip in ...

Catalina-Ant for Tomcat 7

I recently upgraded from Tomcat 6 to Tomcat 7 and all of my Ant deployment scripts stopped working. I eventually worked out why and made the necessary changes, but there doesn’t seem to be a complete description of how to use Catalina-Ant for Tomcat 7 on the web so I thought I'd write one. To start with, make sure Tomcat manager is configured for use by Catalina-Ant. Make sure that manager-script is included in the roles for one of the users in TOMCAT_HOME/conf/tomcat-users.xml . For example: <tomcat-users> <user name="admin" password="s3cr£t" roles="manager-gui, manager-script "/> </tomcat-users> Catalina-Ant for Tomcat 6 was encapsulated within a single JAR file. Catalina-Ant for Tomcat 7 requires four JAR files. One from TOMCAT_HOME/bin : tomcat-juli.jar and three from TOMCAT_HOME/lib: catalina-ant.jar tomcat-coyote.jar tomcat-util.jar There are at least three ways of making the JARs available to Ant: Copy the JARs into th...
