Maemo: Incompatible application package

Recently I copied some package to the N900 and when I tried to install it from the FileManager the installation failed and I got following message:
Unable to install 'qt4-homescreen-loader'. Incompatible application package.
The workaround is to install it manually from the XTerm:

sudo gainroot
dpkg -i DEBIAN_PACKAGE_FILENAME

In order to get the root access the certain application needs to be installed. More information can be found here.

I didn't dig into the problem so it might be that there was really something wrong with the package.

WinXP guest (VMWare Player) hangs every few seconds on the Ubunut 10.04 host

WinXP guest (VMWare Player 3.1.2 build-301548) hangs every few seconds on the Ubunut 10.04 host. To solve the problem add the following lines to your .vmx file:

MemTrimRate = "0"
mainMem.useNamedFile=false
sched.mem.pshare.enable = "FALSE"
prefvmx.useRecommendedLockedMemSize = "TRUE"
