How to change domain/site url of WordPress?

Last week I ordered new domain called for my website and I would like to move my WordPress blog system completely to this new domain. You’ll find a lot of articles and instructions in internet for this problem but in this small blog, I would like to illustrate a much more simple method to do that without breaking down the current blog system. The concept can be applied for WordPress but also for any other system and is pretty performant because of taking advantage of server resources.

Change domain name

Dear my readers,
Because the old domain name is a Vietnamese name and I think it’s very difficult for other users to remember it. The new one is English and however the word is still not in dictionary. Great thank to Mr Vinh Dang for this suggestion. According to him, he thought of domain name Facebook and wanted to make a “bigger” one. Therefore the word “desk” came to his mind. Of course, a desk is much bigger than a book. :). The new domain name satisfies me, just new word and meaningful.

I have just successfully moved databases and file from old one to this new one. If any link is broken, please let me know. New domain, fresh start again and I hope that I have more time for writing about many interesting topics about programming and it security.

Have a nice weekend and FC Bayern will win Chelsea tomorrow 19.05.2011. :).



C# – Host Microsoft Chart in WPF application

How we provide our customers the way to display their data is a important feature of every software for data management. Maybe the users want to use Bar, Line, Pie, Pyramid chart… someone wants to display as 2D and the other wants 3D for his plotting. The financial prefer Kagi, Renko, Point and Figure chart… meanwhile the statisticians maybe use Bar and Column, Cylinder or just simple Line chart. Because of these numerously different requirements we need a stable chart library flexible for customizing and extending. We can make ourselves one or there are a lot of candidates out there in internet such as ZedGraph, Telerik component, DevExpress component… But my favor is Microsoft Chart included in .Net Framework. The components of Telerik, for example, are beautiful with their animations (in WPF) and have a lot of advance features. However the structure of this framework is not stable with breaking changes with new released versions. The Microsoft Chart provides us all simple features necessary for data representing and is very stable. We can use it on Windows Forms or WPF or even on ASP.NET website.

Burghausen Castle

Spring is coming, time to make some excursions inland and long tours outland. This time is Burghausen castle, the longest castle of the world. It lies over the border between Germany and Austria.

The special significance of Burghausen Castle derives from its historical importance as a sovereign castle belonging to the Bavarian Wittelsbachs and its architectural standing as one of the most magnificent examples of late medieval fortifications. The massive stronghold was the most effective fortress in the country and embodied the power and representative ambitions of the Bavarian dukes.

From 1255 to 1503 the castle was the second residence of the Lower Bavarian dukes, whose seat was in Landshut. As a safe family residence it served many different functions during this period: it was a court for the duchesses and the home of their children, and it was the residential seat of the ducal heir and his wife and of widows from the ruling family. It was also in this well-fortified complex that the Rich Dukes of Bavaria-Landshut kept their gold and silver.

The best-known resident was the wife of Duke Georg der Reiche (Georg the Rich), the Polish princess Hedwig, whose marriage to the Bavarian duke is reenacted with a famous medieval pageant held every four years, the Landshut Wedding.

Burghausen Castle, which has a length of over 1,000 metres, is one of the longest castle complexes in the world. With its still almost intact ring walls, it runs high above the town of Burghausen along a narrow ridge between the Salzach River and an oxbow lake, the Wöhrsee.

The complex is divided into five large courtyards, which were originally all protected by moats, portcullises and drawbridges. With their fortified walls, gates and towers and the service and residential buildings for court officials and craftsmen, they set the scene for the massive main castle grouped around an inner courtyard which crowns its southern tip.
