Are you able to understand 32 lines of Java code in a short time? Let's see. This article explains why understanding Java code is difficult, and how a sophisticated static analyser like 4D Ariadne can help. We have created a short case study on code comprehension to help you compare your skill with that of our developers.
I normally think in terms of Continuous Integration and Continuous Delivery. Where does “Continuous Test” fit in? Paul Duvall, a co-author of the great Continuous Integration book, describes continuous testing as running as many tests as possible with every code change in an article on DeveloperWorks.
"When should I consider moving my project to a Foundation?" Of course the answer is always dependent on the project but I think there are a couple of general scenarios...
Fear and aversion are caused by sheer ignorance. When you gain knowledge on a competing framework, fear can turn in two directions.
If you ask most developers, they will tell you that working in maintenance sucks. Understanding and fixing somebody else’s lousy code is hard. It’s tedious. And it’s frustrating – because you know you would do a better job if you were given the chance to do it over and do it right.
Did the test fail due to an application bug or is it the environment? Once again, the dreaded chant of “it works locally” is taken up. What most people fail to understand is that the failing test is the first sign of a communication breakdown between developers and sysadmins.
Even if you think you’ve done a good job of explaining something, the receiver of the communication decides whether or not that’s the case.

Lately the proxy configuration of my network has been changed, and moved from a transparent proxy, that required no configuration, to a “standard” proxy which requires a configuration script. Unfortunately NPM doesn’t pick up the proxy configuration of Windows...
Languages like C# and Java enforce the everything-is-an-object paradigm. You can’t just write a function; you have to write member functions of an object.
A recent survey asked more than two hundred I.T. project managers a simple question: what is the greatest threat facing software-development projects today? Over ninety per cent of those polled replied with a single-word answer: zombies.
Last week I spent a couple of hours setting up a new service, dubbed BitSyncHub, that will accept POST requests from Bitbucket and synchronize a (Mercurial) repository with it's Github mirror.
You've probably read about those big name dotcoms that deploy new features to production up to tens of times a day. For most startups bringing features to production is still a manual, at best semi-manual process.
There was a new release of Juju this week, 1.11.3, that brought a “small feature” with a big impact on your AWS bill. You are now able to deploy multiple services on one cloud server instantly. Before Juju started a new server per service which resulted in a potentially high AWS bill.
How can developers and security people get along with each other better than what they tend to at present?
A couple of days ago, Synology released the open beta of DSM 4.3. Somewhere hidden in the release notes there was mentioned that the NAS now officially supports the hosting of GIT repositories. This is great news for all programmers.
Quality and productivity are, of course, important things. I certainly wouldn’t continue to practice Test-Driven Development if it added defects or took a significantly longer time to create functionality. But that’s not why I practice TDD.
A common feature in software systems is to allow users to define their own fields in data structures. Consider an address book - there's a host of things that you might want to add. With new social networks popping up every day, users might want to add a new field for a Bunglr id to their contacts.
