Preparing for the Future: IPv6
More and more providers change to dual stack to make their servers ready for the future. Dual stack means running IPv4 and IPv6 parallel on servers.
The magic date for several providers is 6 June 2012, from then on dual stack should work for daily use. I want to participate and made this site accessible through IPv6 today.

Dockstar: new Kernel 3.3.3 ready to use
As you may have noticed, we were discussing things about newer kernels and drivers in the comments of Dockstar/Goflex: new Kernel 3.1.10 ready to use. With that in mind I started up my VM and looked at what I've got there in /usr/src - there was a compiled 3.2.1 that initially wouldn't boot. But following davy's guide to upgrade U-Boot makes that one boot.
Taking a look at kernel.org made me jealous... Here it is - a fully working 3.3.3:
Say hello to…
...the new forums of my website. It's been a while now I was talking about it.
Here they are: Click the link in the main navigation to get there. For the future I am planning to integrate the forums with wordpress for better navigation and topic exchange to see what's going on there.
There is some conversation going on in the comments here. Feel free to register and start dockstar, goflex, coding,... related topics to get everything at its place more easy to handle rather than in the comments.
Some words about
With the first introducing of my forum plans I was thinking of vBulletin. I've seen a couple of software solutions and I really love working with such a forum. But as the participation in the vote was less than expected I decided to try some solutions free of charge.
MyBB in my eyes is the best you can find if you have chosen the cheapest way. Let's see about the movement going on in the forum in some time. If there would be enough donations, I definitely consider buying a vBulletin licence!
Thanks

Forum
First of all: Thanks to all voters!
As you can see a forum is appreciated. But over all I decided not to add vBulletin for now due to the low number of voters against licence costs.
But a free one should show the response on a forum. Till the end of the month everything should be set up.

Server
Don't worry if you don't reach my site someday next week.
I will be moving to another server which means I have to update the A-Records and some of you might have the old ones in their dns caches. To get the new ones just wait a couple of hours or flush your dns cache.
Update 19.03.2012
Everything worked flawlessly, moving should be done! Hopefully you don't encounter any problems - but if you do, please email me.
Chrome Extension: DHL Track and Trace
Do you often buy things in the internet? Are you annoyed of copy-pasting the tracking id from the delivery confirmation mail to the DHL website?
My extension makes this problem to be a thing of the past!
Rightclick on a selected tracking id: The context menu entry takes you directly to the DHL infopage of your parcel.
On the optionspage you can make a list of urls where this extension should be enabled. In addition the language of the DHL webpage is selectable.
You can find my extension right in the Chrome Webstore (DHL Track and Trace | DHL Sendungsverfolgung | Suivi des envois DHL).
Security: SSL for free
When I was visiting a friend's webblog some days ago I realized he was using a valid ssl certificate. My first thought was: How did he get the cert, I want one for my site!
With that in mind I searched the web to get some more information about certificates for free. The solution is you can get class 1 ssl certs validated for one year for private use. It allows you to secure the root domain and one subdomain of your choise.
I want to show you how easy it is to get one of these from StartSSL and how you set up apache to secure the communication with your site.
1. Creating the Certificate
First of all you need to generate the private and public key of your server:
openssl genrsa -out example.com.key 2048
Now you need to read that private key to generate certificate signing request (CSR). You will be asked for some additional info like organisation name and so on, but you can leave them default, because StartSSL will ignore them.
openssl req -new -key example.com.key -out example.com.csr
Dockstar/Goflex: new Kernel 3.1.10 ready to use
It's now been a while since I installed the 3.1.0-1 kernel from sid and made some testing. But I don't like the LED beeing solid green during boot, I want to see whats going on. Thats why I decided to compile 3.1.10 with heartbeat from this erlier article: Dockstar: new Kernel 2.6.38 ready to use. The config is based on sid's 3.1.0-1, if you want to take a look at it, you will find it here: config-3.1.10-dockstar-shyd_1.2
It supports several devices like wifi, webcam, audio or dvb.
Some of you might ask why I didn't build 3.2.1. I did, but it wouldn't boot.
What is your opinion?
It's been a while now since my blog became popular and I have more than thousand visitors a month. Thank you for your confidence and comments you made!
What about something new in 2012?
I am thinking of adding a forum to this blog in order to let you post your projects and modifications (e.g. at the dockstar) with the chance of being featured on the blog. It would let you answer someones questions without waiting for my reply. When I look at google analytics there are a couple of sites out the web discussing my articles. Why not discussing here with the chance of some words from me?
Before setting it up I want to know what you think about this idea. If you participate the poll I would appreciate you comment on your choise.

Remote printing: Debian and Google Cloud Print
Have you ever heard of google cloud print? It allows you to add your printers to the cloud and share them. You can print on them from any device supporting this service, even if you are on another network. This sounds pretty cool, I gave it a try and I am really amazed.
None of my printers doesn't support cloud print directly, so I need a google chrome installation to share the printer. But I don't want to have my computer to run when printing remotely. There is a project called Google CloudPrint on Linux which allows you to use this nice service from the command line. At this point the dockstar or the linkstation joines the game.
Shairport: Debian as Airtunes Server
Recently some friends and me were talking about streaming music from iTunes to my dockstar with an usb sound device connected.
I knew there is a solution, so I started some research an found shairport at mafipulation.org. The project looks quite interesting and I tried to set everything up that I am able to play my music remotely.
First there are some dependencies you need to install:
apt-get install build-essential libssl-dev libcrypt-openssl-rsa-perl libao-dev libio-socket-inet6-perl libwww-perl avahi-utils pkg-config
Now all you need to do is download the sources, make and install them:
Get the sources at github.com/albertz/shairport/downloads.
