I am very happy about the performance of Kubuntu 11.04! My old laptop only has Duo T7500 and 4GB Ram. T7500 has only 2 cores(2Ghz) and 4MB Cache. In such configurations, I found my old laptop is not much worse than my new laptop(Win7) which has i7 2630 QM and 8GB RAM. 2630GQM has 4 cores (2Ghz) and 6MB Cache. I think at least 2 times powerful than my old laptop, that has double number of CPU cores and RAM. Kubuntu is done a great job!
I got 12" old laptop, Asus F9 Series. It has Duo T7500 and 2GB RAM with Windows Vista Home. That is a bit old. Today, I did an upgrade. I change the RAM to 4GB. Originally, I wish to upgrade to 8GB. But the laptop only has DDR2 slots. The computer I went today has 2GB DDR2 RAM. Therefore, 4GB is the max I can have. I hope that will have good enough.
I did an OS upgrade too. I changed to use Kubuntu. That is lighter than Winodws, I think! Moreover it got more modern interface than Windows Visa.
Now, I successfully did the upgrade. The laptop is with Chrome, Mono and Java EE too! The most important is its performance is still OK!
(P.S. Kubuntu is installed successfully, all hardware drivers are working)
I wish to a rich user interface for my website. Well, HTML 5 is the best choice. But HTML 5 is still not easy to do some tasks, such as animations and charting. Then, Flash is the second best choice. A lot of platforms support this. But I need to learn it from scratch. In this case, Silverlight is a much better option. It is similar with WPF which I have learnt before.Moreover, the Silverlight is a component-based components. I can use some third-party controls to build the interface. Those third-party controls can be download from internet freely or just needs to pay a small amount of money. This can reduce the amount of coding. So, I choose to learn Silverlight
I have installed Silverlight 4 Toolkit - April 2010. I tried to drop a component in a xaml. But I got an error,
"Unknown namespace http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit". I searched a solution for a while, but no luck at all! Finally, I got the cause I forgot to install Silverlight SDK4! I am so silly!
After I installed it, that works! Please remember set your visual studio project to use Silverlight 4 too!
