Do you program or do you already TDD?
If you prefer to do TDD you will love the eclipse plug-in called MoreUnit. It is as simple as powerful. All it does is executing tests from corresponding productive class and makes it very simple to change between them.
Just press Ctrl-J (like Jump) to jump from test to implementing class and the other way. Or press Ctrl-R (like Run) to run the test regardless if you are in the test or the implementation class.

Here I will show how to get bytes from a ByteBuffer. This isn’t as simple as it sounds.

Since a few weeks the new mockito release candidate is available. So I think it is the right time to place a new post. Here I will show the differences between ArgumentMatcher and ArgumentCaptor. Most developer will first see the ArgumentMatcher and use it. What can be done with ArgumentCaptor is often not seen. With the sample I will show that an ArgumentMatcher should not be used to fetch arguments. For this work there is the ArgumentCaptor. The Matcher should really be used to check if an argument matches or not.

The idea of variable prefixes

The idea of prefixes on variable is “very” old. They are used to tell the developer what kind of variable he is using. The first prefix for example is m_ and the conclusion is this variable is a member. When I learned programming we had to give the developer more information in case of a member. Like the type of it like an integer became m_i.

A few days ago, my epia device gave up it’s live. So I was looking for a temporary alternative to start the harddisk.
Looking back it was very easy to get it run in my desktop, to get the data I’m storing on it. (A little database and some Webservices)

Why should we leave apache common collection?
There are several reasons to change the collections framework.
Since the apache collections should be backward compatible it would not be possible to change to a actual Java version. It would be necessary to change to another collection framework (or write all the stuff by yourself).
There are several projects which created a collections framework by themselves or took the apache collection library and upgraded it with generics.
Guava is a project like the apache commons. Since a few weeks the Google collection project is now in the guava project integrated.
I just will take a view to the collection package in the guava library.
What is in the guava-collection?

Since a few days I’m using a plugin in eclipse which allows vi like editing. It’s called vrapper and can be found under http://vrapper.sourceforge.net. It is a very good light weight alternative to commercial vi plugins. In my opinion there are not more disadvantages as in other vi plugins.
Sometimes it has hangers, this means it does not fall back to the main state instead it hangs in any command mode. In this rare cases normally helps to restart the plugin with the icon in eclipse.
The installation is very simple, only add the stable update site (http://vrapper.sourceforge.net/update-site/stable). Or if not possible to use the update site just download the file from http://sourceforge.net/projects/vrapper/files/, just copy the files into the plugins directory .

If you like to use vi commands look in and check it out.

Since we use the new terminal client from microsoft we register sometimes obscure reactions. For example: program flipping while pressing the tab key solo, get the dialog which is shown normally pressing ‘Ctr-Alt-Del’ while pressing the delete key solo.

Since a few months I’m working in a new project where we have remote PC’s for developing. Since they updated the clients from Windows XP SP1 to SP3 we we have the new remote desktop client. Now it’s possible to show the terminal client on two monitors (or a monitor with a resolution over 1600×1200). We just had to do the following:

1. create a Shortcut to mstsc.exe
2. add as params
• /w:2560 (The screen witdth)
• /h:1024 (The screen height)
• /v:hostname

The link will look like this: mstsc.exe /w:2560 /h:1024 /v:hostname
Our expirience was it works not bad. The only thing we noticed was, the client needs more power.
