Breaking Out of the Familiarity Model

What makes code so dense that it's not acceptable to programmers and they complain about its incomprehensibility? Unfamiliarity is one of the culprits - people don't complain about regexes since they are familiar with them, but will surely complain of something else which they are not familiar with.

Public Service Announcement: Your Build is Leaking (and how to stop it)

Use Maven. Gradle, or Ivy? or any other tool that depends on a remote repository? (Which is just about every build tool these days.) If you do, there’s a good chance that your builds are constantly leaking information about your projects, and if you don’t take some simple measure to protect yourself external actors can learn a lot about your internal projects.

Continuous Delivery Using Maven

I’m a big fan of Ant, I’d usually choose it (or probably Gradle now) over Maven any day of the week, but there was already an existing Ant build system in place, which had grown a bit monolithic (that’s my polite way of saying it was a huge mess), so I didn’t want to go there! And besides, the first project that would be going into the new continuous delivery system was a simple Java project – way too straightforward to justify rewriting the whole ant system from scratch and improving it, so I went for Maven.
