Manage Disk Partition
In Windows, there is not a good partition manager. Yes, you can buy some third parties software. But there is a free alternative choice, GParted. GParted is the partition manager for Linux. But it have a LiveCD ISO. So, you can boot your computer with the LiveCD and resize your partition.
Google Map is not working in Atahualpa Theme
I have installed an Atahuapla Theme version 3.2, in my wordpress blog. I found the google map in my blog is not working well. The map image is not showing. The problem is so easy to slove. I updated it to the latest version 3.4.4 and disabled the inline Google map plug-in. That works fine. I will use this, because that looks tidy. Moreover, I can add my own image as the header!
Single Origin Policy on AppEngine
I found out the work around for Single Origin Policy for cross sites client scripts and AppEngine. But that is not very good. That is not a pure client side solution. The client scripts need to request a PHP (or scripting files) in the same server as a proxy. That PHP script will forward the requests to AppEngine and get the responses back to the client scripts.
GWT Client Side Script and AppEngine in separated servers
Google Web toolkit and AppEngine are working together very well. But I found a lot of tutorials showing GWT script and AppEngine are sitting in a single box. But I believe that should be able to send RPC calls to a separated servers. Google Map GWT library is to send RPC calls to Google Map Server. So, there should be a way to write an application with a separated GWT client script and AppEngine.
(Note: I found after the service class casted to ServiceDefTarget, I can use setServiceEntryPoint to a remote server. But our web browsers has Single Origin Policy, which blocked the request to remoted servers. I am checking whether any work around.)
Ubuntu Remix 9.04 - HP Mini 1001 Speakers problem gone!
During weekend, I got the update of linux-image-2.6.28-15. Then my HP Mini 1001 Speakers got sound now! Previously, I can't get my speakers working on Ubuntu Remix 9.04. This is the power of Opensource Communities. They can fix bugs quickly.
One last point, please remember to mute the headphone and unmute front speakers from the mixer. I can't get it on the first boot from the update, because the front spearkers are muted by default.
