hotdawgz asked: the other problem with using a imac as a display is; imacs only take input signals from thunderbolt devices, at least de new ones, if you only have a displayport signal the imac won't recognize it and won't display anything... kinda uncool, i would have loved to use my imac as a display for my raspberry

How to Safely Shutdown or Reboot Your Raspberry Pi →
Title says it all, but there’s a bit more useful information too. Personally, I’ve always used “sudo halt”.

Learn Python The Hard Way →
Finally time to start learning Python. I’ve done a fair amount of programming as a hobby and in education and am competent in Objective-C, and familiar with Java and PHP (and some others). All the Raspberry Pi stuff seems to favour Python, so I’ve taken the plunge and am using this book to learn. I’ll see how I get on and post a bit more on my experience with the book in a week...

SSH
Something I had overlooked in my previous entries was the lack of any guide to SSH (Secure Shell). This basically enables you to access a computer (including, of course, your Raspberry Pi) using a command line interface on another computer connected via a network - so like running the Terminal application directly on your Pi, but on another computer. This is very useful if you’re running...

Tips Tested on Raspbian
Eager to improve the performance of my Raspberry Pi, I installed the Raspbain-based SD card image today and have tested the tips/guides on this tumblr and all work as expected. I hope to continue to add more within the next week or so.

Auto-Login and Auto-Launch Services
If you’re planning on using your Raspberry Pi as an appliance, you’ll want it to automatically login and load LXDE (the GUI). You may also want to do this if you are just tinkering around with the Raspberry Pi (as I am at the moment) and are using it without a monitor using a VNC server.
This eLinux Wiki guide explains how to do it, but if you want to start your VNC server instead,...

Finding Your VNC Server Using Bonjour
Another post for Mac users. If you’ve followed my previous post to setup Avahi for AFP auto discovery, you might want to do the same for VNC.
To do this, add a new service under /etc/avahi/services. Using Terminal:
Run “sudo nano /etc/avahi/services/rfb.service”
Enter the following: <?xml version="1.0" standalone='no'?> <!DOCTYPE service-group SYSTEM...

File Sharing With AFP and Auto-Discovery With...
This post will only interest you if you’re using a Mac. AFP (Apple Filing Protocol) is the protocol Macs use to share files over a network. This post will guide you through setting this up using Netatalk. It will also cover setting it up to be easily accessible without the IP address.
To install Netatalk, simply use apt-get:
“sudo apt-get install netatalk”
You should now be...

Resize SD Card Partitions
Once you’ve copied the Linux image to your SD card, be sure to resize the partitions to ensure all the SD card’s space is available (or you can create an additional partition). Follow this eLinux Wiki guide, which explains how to do it from Linux and from the Raspberry Pi itself. If, like me, you’re not running Linux on your main machine, follow the the steps in section 5.2.

Chromium
The RPi version of Debian comes with the Midori web browser, but you might want something a bit more mainstream, so try why not Chromium.
To install simply run “sudo apt-get install chromium-browser” from the command line and it will appear under Internet in the Application menu (icon in the bottom left corner).

Setting Up a VNC Server
So you’ve got your Raspberry Pi setup, but what if you don’t have a dedicated monitor to use with it (for example, mine’s connected to my TV). How can you use it without disrupting your setup? VNC (Virtual Network Computing) allows you to see your Pi’s desktop and control it remotely using another computer running Mac OS X, Windows or Linux (and other devices too).
The VNC...

Admin (root) Password
If you’re using the Debian “squeeze” flavour of Linux you may have seen the “Enter administrative password” dialog box pictured below and stumbled when trying to authenticate as the admin user.
The reason, if you’re using the standard “pi” user account, is that you’re not an admin user and you don’t have the password for the...
