After first login (user pi password raspberry), you are advised to run the __''sudo raspi-config''__ script.
I did that to
* Expand root partition to fill SD card
* set the Timezone
* set the Locale
* run an update (apt-get)
After first login, you are advised to run the ''sudo pi-config'' script.
I did that to set the Timezone and Locale properly.

!! Network config
Because pi is running as a server, it needs a static IP address, so change ''/etc/network/interfaces'' and edited the line for ''eth0'':
{{{
#iface eth0 inet dhcp
iface eth0 inet static
address 10.0.0.186
netmask 255.255.255.0
gateway 10.0.0.138

!! Reboot after plugging in USB stick
Because I only had a 2GB SD Card (I already ordered a 16GB class 10 card, next week in) and want to put more stuff on it, I inserted an extra USB stick in, this immediately made 4 of 5 LEDs go out. I suspect this required a short peak of current making the voltage reduce too much. It did automatically reboot and was back up in about 30 seconds.
!! Performance
The performance of the thing is (as expected) not as we are used to with our Intel boxes. Also having a slow SD card makes the thing even slower. If you use ''top'' you see a lot of IOWAIT.
!! Installed stuff
* locate
* vim
* default-jre-headless (and that just fitted on the SD card, only 88MB free)
!! JSPWiki
The goal is to see how JSPWiki runs on it.\\
We need a container first, so unzipped the latest tomcat (7.0.34) to /mnt/sda1/apache-tomcat-7.0.34.\\
The created the webapps/wiki directory and unzipped the latest (2.9.1-svn-11) and tweaked jspwiki.properties (baseURL and pageDir and attachmentDIR).
Firing up the stuff, takes a loooong time, see attached [jspwiki.log], but it just works (as expected :-) )
Created an extra DNS alias for my domain and added some proxy statements to my main host, the wiki is now accessible at [http://raspberrypi.computerhok.nl/wiki]
! Performance tomcat / JSPWiki
See for details the [logfile|jspwiki.log], but some performance related messages:

You also notice the first time you get to the wiki and all JSP's have to be compiled, that takes several minutes !
