Every now and then, you come across developing an application, that sends email. How to simple test this application? It’s easy, if you have an own mail server. For Windows, there is the very simple smtp4dev application, that listens on localhost port 25 and displays all emails that would have been transmitted. A similar but cross-platform tool is FakeSMTP. For a server, fakemail might be worth a look at.

I recently started developing an app for Android. The app is nothing complicated. A few screens which display data from a webservice. The data are events like “having dinner together” and you can register to join the event. As being new in Android programming (and this time, I wanted to create a “real” native Android app, not a PhoneGap / cordova based app), it’s quiet a learning experience necessary.

This post is about, how your git history might look like, if you consequently fix bugs on branches
and merge this bugfix-branches into the release branches. In this case, I used the method described
earlier in “Roadmap and source code branches” in
New PMD Release 5.4.0:
Always create a new branch, that can be merged in the release branches, determined by git merge-base.
Then, after the bugfix, merge this branch into the release branches, avoiding a fast-forward merge
by using git merge --no-ff.

You are using PMD in your project. After a while, you start customizing your ruleset as described in best practices and how to make a ruleset. But the project grows and grows and it soon consists of several sub modules or even separate projects maybe even living in separate source repositories. The how can you share the ruleset, so that it can be applied to each project?

This post is about how to fix a bug in PMD - the project mess detector. PMD is a source code analyzer tool for Java and many other languages. It checks your source for common programming mistakes so you don’t repeat them. However, as with all software, it is not perfect. PMD itself has bugs which lead to either false positives, e.g. when PMD reports a mistake which is not really a problem. Or to false negatives, which means, that PMD doesn’t detect the potential bug.
