Today I got an eco button from my colleague. It is a hardware button with a green flashing light (is that eco?) which can be connected to your computer. With software installed, your computer will be put in stand-by mode when you press the button.

Because I use my computer the whole day for development, I [...]

Last week I bought a nice gadget at our discount supermarket (Aldi). The gadget is called a Digital notepad and makes it possible to record your notes while writing them down on paper. Your writing is stored on the internal memory as vector data. There is a lot of software supplied, but using them is [...]

With Openfire installed (http://www.johandekoning.nl/index.php/2009/11/30/xmpp-and-wcf-net-installation-of-openfire/) it is time to create some users and connect with a XMPP client to the server.
User management
Because of the simple installation, users created on the Openfire server are stored inside the embedded database. To add new users, make sure that the server runs and open the administration console (default address http://localhost:9090). [...]

In my previous blogpost, I talked about my goal to make an XMPP implementation within .Net based on Windows Communication Foundation. Before I can start, I had to find out how a normal XMPP stream would be send/retrieved between client and server.
In this blogitem, I will explain the steps I took to install the OpenFire [...]

Hummm… XMPP and WCF? Is this not a blog page about Android or other Google related stuff. That’s partly true but as a Microsoft .Net developer I am more interested in combining the best of both world. I like Google and Microsoft products. I really like the open source vision of Google. But when it comes [...]

Today (or yesterday late) I started download and building the source of Chromium OS again. As a described inside my blog and at http://groups.google.com/group/chromium-os-discuss/browse_thread/thread/ba8ddf13edece9a6/647d2632e8c2d615?lnk=raot I got a blue gradient screen after login.
One of the reponse of this post said something about the different version of the gtk library which are used http://code.google.com/p/chromium-os/issues/detail?id=676 Ubuntu 9.10 makes [...]

Note: for my first build I used Ubuntu 9.10. It looks like there are some issues with using this version so for my second build I am using Ubuntu 9.04. Some of the part of this blogpos became obsolete because those issues don’t exists anymore. I marked those part as red. When updating this blog [...]

Now that building Donut for Dream is not working at the moment (because of the prioritary files) and it is unkown if it will be possible (because of the memory size on the device) I become interested in porting Android to different hardware.
It would be nice to have hardware with the complete specifications. This way [...]

The first attempt was not a success, but based on the discussion at http://groups.google.com/group/android-platform/browse_thread/thread/929aa624d2da63a7 I decided to make another build with less proprietary files.
Before the patch with the extracting and adding of the extra proprietary files was applied on the source tree (master, cupcake and donut) there was a small list of proprietary files. I [...]

Yesterday I started downloading the source code from the donut branch again to see if it was possible to get it running on the HTC Dream (Android Dev Phone).
I build the source the same way as building cupcake but this time I used the defaults (like the prebuilt kernel and wlan.ko module) and did not [...]
