App Inventor Hands-on
Finally, I got an account for App Inventor. That is very easy to use. That is really a drag and drop development. Moreover, that is so great, most of interfaces are in web.
But that is a "strange" feature. All applications logics,such as Button Click, are done in something Block Logic. That looks like this:
That is the logic for a tip calculator. I am trying to make Label4 display "Text1 *(Text2/100)". As a programmer, I am prefer to do it in a way of code behind. In addition, I don't think this kind Block Logic can do some complex application. But that is good for doing some simple programs, such as display a RSS feed.
The Priority Inbox of Gmail
I found that is a new service in Gmail. Gmail can pick the important email for you. According to the video from Google about Priority Inbox of Gmail, the system will detect the importance of email by whether you reply the sender before. That sounds like not very "smart". But you can have fine tune the email by using plus and minus importance buttons. That is good enough. Well, I don't use my gmail account a lot, so I don't know how's good of this function yet. I think I will write another post later to follow up.
How to clean up all ".svn" folders
When I do a deployment or try to "unlink" a project directory from SVN, I need to remove all ".svn" folders. I know we can use Windows Search to find all folders call ".svn" or run a few lines of command in Linux. But that is not enough easy. I found a tool calls SVN-Cleaner. You just need to right click the folder you want to delete its ".svn" folders and select "Remove all .svn" in the window context menu. Then Job Done! That's easy!
iPhone 4 Vs Galaxy S - Screen
My colleague got an iPhone 4. I found even my Galaxy S got super amoled, the screen quality is bit poorer. I am a bit sad about it.
Galaxy S GPS Accuracy Problem
There is a known problem for GPS Accuracy in Galaxy. After my Galaxy S upgarded to JM1, that doesn't help at all. I tried to check my location, it spot me at the street next to the location where I stay. That is around 200m away. I hope the future 2.2 upgarde can fix it!
