This feels window-ish to me

I know Umbraco is supposed to be simple and hassle free, but althought I configured a database use with this script (because the SQL Management Studio doesn’t run …..):

CREATE USER shop_u FOR LOGIN shop_u;
USE shop_db;
GRANT ALL ON shop_db To shop_u;

It doesn’t accept it as login credential in the umbraco installer. Propably the GUis does a bit more, than there is documents in the Reference manual….

But there is the nice link ‘instructions’ pointing to Microsoft SQLite equivalent: SQL Server 4 CE:

But somehow no one cared to fill it with content

But hen, hey, its beta. So you can’t blame them. SO I just google and search for the download:

Oh cool, its the top link! Lets click it:

And I land on a bing-ternal search result page and whenever I click the ‘Download details:….’ …. it just gives the same page again.

This little image story sums up pretty well, what I experience when I work with microsoft technologies.

fresh umbraco: “The page cannot be found”

After following the guide and installing .NET 4.0 I suddenly had a “The page cannot be found”.

Then I clicked through the IIS manager and .NET 4.0 was prohibited.

after I enabled it, it started working.

I spent now almost a day just installing umbraco, configuring the database and so on. It starts working, but I don’t get warm/fuzzy about it.

Passwordless ssh logins from your OS X Box

From my Linux time, I know that ssh-copy-id is extremely handy. Sadly its not available on OS X.

But nonetheless, thats how you can setup a password less login to another host from OS X:

# Generate your local public/private key (if not already done)
# (you can press enter to accept the defaults)
# Create the remote directory (especially for Windows hosts)
ssh [email protected] mkdir "~/.ssh/"
# Copy the public key to your remote host
scp .ssh/ [email protected]:"~/.ssh/"
# Add it to the authorized_keys File
ssh [email protected] "cat ~/.ssh/ >> ~/.ssh/authorized_keys"

And your done!

Transfer Files with Remote Desktop Connection for Mac

Since I work for, which is a Mac friendly company, I started to like Macs. Yes, its true.

From time to time I use RDC for Mac to administer some Windows boxes and this is how I transfer files to them:

Share Mac Directories as Windows Drives

  • go to the Preferences
  • choose Drives (it should be called Shares, but anyway)
  • choose the Mac Directory you want to share

and this is how it will look like on My Computer

(gosh, Windows looks ugly)

Restrict a Socket Server to specific IP adresses

Just as some kind of promotional code, I implemented a Webservice based on Axis and its SimpleAxisServer. It turned out, that the SimpleAxisServer was to simple:

  • it only filled certain fields of the MessageContext and particularly not anything to see the Remote IP Adresse.

After some thinking I decided to fully copy the SimpleAxisServer and Worker to my ow classes (because the are not made to be extended….) and changed some minor stuff.

First of all, I use Commons Configurations to load me a list of IP Adresses and Hostnames. Like:

allowed_ips =,,

I convert these into a List of Java InetAdresses with that:

	public void setAllowedHosts(String[] hosts) {
		for (String host : hosts) {
			try {
			} catch (UnknownHostException e) {
				log.error(String.format("Allowed IP could not be set successfully.", e));

and in the run() Method of my SimpleAxisServer I added some lines:

	public void run() {"start01", "SimpleAxisServer", new Integer(getServerSocket().getLocalPort()).toString(),
		if (allowedIPs.size() == 0) {
			log.warn("No IP Restrictin inplace. Service is exposed to everyone.");
		} else {"Service Call are allowed from IP: %s", allowedIPs));
		// Accept and process requests from the socket
		while (!stopped) {
			Socket socket = null;
			try {
				socket = serverSocket.accept();
				if (allowedIPs.size() > 0) {
					if (!allowedIPs.contains(socket.getInetAddress())) {
						log.debug(String.format("Discarding connection from: %s, because it isn't in the list of supported IP's: %s",
								socket.getInetAddress(), allowedIPs));
						socket = null;
			} catch ( iie) {
			} catch (Exception e) {
				log.debug(Messages.getMessage("exception00"), e);
			if (socket != null) {
				MPAxisWorker worker = new MPAxisWorker(this, socket);
				if (doThreads) {
				} else {;
		}"quit00", "SimpleAxisServer"));

Making a Java UI for editing Properties

Java Properties suck. But Apache Confoigurations sucks a bit less, so I’m using it to have a small configuration framework.

It consists of

  • Constant values, like the Application title, version, and so on.
  • Default values, like database url, username, …
  • User Properties, which are generated based on the default values

Then I have a JFrame which takes the user properties and iterates and displays them in a gui.

The final UI looks like this:
