Welcome!
You have come across the ZephyrSoft home page. Here you can download some tools I developed over the years and also actively take part in further development. I wrote these programs because there was no free solution, at least no satisfactory one. Some were created especially for Koinonia Fellowship in Hannover, Germany.
I am also accepting work offers as time permits. If you want me to develop your software in Java, C# (.NET/Mono), PHP, Perl or other languages, you are invited to ask. Further information is available on the page Custom Software Development.

And just in case you wondered what "Zephyr" stands for: it's Latin and means "westerly winds". I chose it as my code name (or brand name) to offer software and services.
Certificates and the JVM
The recent events revealed that the internet is not a very safe place. If you don't encrypt your data, it is likely to be analyzed by third parties like intelligence services. So you start to encrypt everything because you care for the safety your customers data. You managed to get it done without extra budget because you use a self-signed certificate - but oh, what is this? A nasty ValidatorException saying "PKIX path building failed". What now?
Developing Android apps in Eclipse
For some time now, Android development in Eclipse made me stumble in one point: the libraries. When you develop an app, there will be some third-party library you can use - and it's easy to do so, just drop it into the "libs" directory. The Android Development Tools (ADT) take care of adding it to the classpath. But what about attaching sources to those libraries so you can debug easily? Nope. These properties are labeled as "non-modifiable" in the appropriate Eclipse dialogs.
