I got myself a RaspBerry Pi. This article is about the things that I learned.

Connect it to a monitor
You can connect your raspberry pi to a HDMI monitor using an HDMI cable giving you a great resolution. You can also use the composite port on the device. In this case the resolution will be medium. Take care that you do not buy a HDMI -> VGA adapter and try to use a VGA monitor. VGA is analog, HDMI is digital. This means you will need a HDMI -> VGA connector not adapter. This difference can easily cost you some weeks of waiting for a device which will prove worthless in the end.
No start without bootable SD card
When I got my Pi, I just started it to see if it works. I did not have an SD card in it and I expected it to show
No bootable medium found
Or something similar. Beware! The Pi will not even start without a bootable SD card in it. Also an SD card that is not bootable does not help. Do not send the Pi back, create a bootable SD card and boot from it.
Create a bootable SD card
http://www.raspberrypi.org/quick-start-guide is incomplete, it does not tell you how to dump your file to SD card, here is how I tried:
dd if=2012-12-16-wheezy-raspbian.img of=/dev/sdc
This worked, the OS came up.
Password
User is pi, password is raspberry
Network
Playing with it in the default config:
tweedleburg:~ # nmap 192.168.178.0/24 Starting Nmap 6.01 ( http://nmap.org ) at 2013-05-23 17:51 CEST [...] Nmap scan report for 192.168.178.43 Host is up (0.0036s latency). Not shown: 999 closed ports PORT STATE SERVICE 22/tcp open ssh MAC Address: B8:27:EB:06:57:BA (Raspberry Pi Foundation)
NFS Server
Using it as NFS Server I get 8 MB/s when writing on it using the command
dd if=/dev/zero of=datei bs=4096 count=10000
Interfaces
- 1 micro-USB for power supply
- 1 HDMI for video out
- 1 yellow composite video out
ideas what to do with it
- print server
- NFS server
- surfstation
- media player
- firewall
- logik analysator
- satelite tuner
