The Day I Met a Customer

Like many developers, I’ve been protected from apparently difficult customers by my managers and left to get on with the important job of “writing code”. But this week I left our office and headed out to a technology park to work directly with one of our customers, and after a couple of days of understanding each others needs I’ve rarely felt so excited about “writing code”, because I know it will be valued.

International Women's Day and the Software Industry

This past Saturday was international women’s day (IWD). A day that should make us men in the software industry think about why so few women study CS and why so many of those who did, never establish a career in the industry. What do we men do wrong, when women don’t feel welcome?

What does it mean for an estimate to be right?

If we choose conformance to actuals as the definition for the “rightness” or “goodness” of an estimate, we’re certainly encouraging overestimation. It’s easier to overestimate and then waste effort as needed to be “accurate” than to underestimate and try to hit a possibly impossible target. Those who ask for estimates using this definition know this, so they are likely to arbitrarily cut the estimate in order to put pressure on development and prevent padding.

DevOps = DevOps Principles + DevOps Practices

Successful, long-lasting movement have a clear manifesto outlining goals and principles. Many DevOps adopters may not be aware of the DevOps Manifesto (created by Jez Humble @jezhumble) nor how successful DevOps requires keeping a clear focus on principles, practices, and value (instead of infrastructure tooling).

Why shouldn't I test private methods?

Why shouldn’t you test private methods? Because the fact you’re asking the question means the method shouldn’t be private – it’s a piece of independent behaviour that warrants testing. The hard choice, the design decision, is where you stick it.

Advice for the New Tech Lead: The Realities of Distributed Development

Let’s face it; not everyone has been there and done that, when it has come to Distributed Development. And if you have, there is a high probability that you were probably in a distributed team, you mostly worked with one group or the other, but not both. These words I will probably keep repeating in the future, but I’m not apologising for them: Never be Complacent.

Don’t sell me agile, solve my problem

A wise, retired CIO told me, “Don’t sell me your solution, solve my problem.” That statement further solidified my belief that I am not “implementing agile” (hang with me), but rather I am solving a problem or a set of problems that commonly occur in enterprise environments.

How (Not) to Create a Permgen Leak

The code snippet is rather straightforward, iterating over a loop and generating classes at the runtime. When facing an Error, the code above is well prepared to catch it and print out the stacktrace. Apparently, the situation is a bit more complex than this - half an hour later I found myself still staring at a somewhat different error message. I

Creating a Secure Deployment Pipeline in Amazon Web Services

Many organizations require a secure infrastructure. I’ve yet to meet a customer that says that security isn’t a concern. But, the decision on “how secure?” should be closely associated with a risk analysis for your organization.

Tracking Agile Velocity

It’s very common for organizations to track the velocity of the Agile teams over time. This is quite a reasonable datapoint to plot. Combined with other data, it might give you some insights when you look back, and insights based on data are typically more useful than insights based on opinion. Remember, though, to keep in mind what the data is, and what it is not.

An open source JVM Sampling Profiler

It's a well known deficiency of most existing sampling Java profilers that their collection of stack traces has to happen at a safe point. A while back Jeremy Manson open sourced some proof of concept code where calls are made to the AsyncGetCallTrace JVMPI method which avoids the need for threads to reach a safe point in order to read their call trace. I've taken this code dump and started converting it into a usable open source project.
