App Inventor Hands-on

admin — Mon, 06 Sep 2010 10:39:12 +0000

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

admin — Fri, 03 Sep 2010 05:56:09 +0000

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

admin — Mon, 30 Aug 2010 12:47:27 +0000

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!

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

admin — Sun, 22 Aug 2010 22:05:52 +0000

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!

The firmware of Galaxy S is upgraded to JM1

admin — Sat, 14 Aug 2010 13:20:30 +0000

I have upgraded my Galaxy S to JM1. Before the installation, I was wondering whether that is Android 2.2 upgrade. That actually that is not. I found that is some improvements in default Samsung application set. I found there are only a task manager added in the default application set and more detailed instructions about unlock screen at sleep mode. That is! They are still Android 2.1.

HTC Wildfire will be arrived at Telstra on 24 August

admin — Tue, 10 Aug 2010 05:03:17 +0000

Telstra has announced HTC Wildfire will be in their shop on 24 August. Moreover, you get it as a pre-paid for $349. I think that is the first pre-paid Android phone in Australia.

Well, let's talk about the phone. That is pretty much standard HTC phone. It got Sense UI and Friend Stream. There are "non-standard" HTC feature. It has a LED flash(but I don't think that is very useful, that is much to use a torch.) The brightest feature is Swype. That is a sliding input method. I got it in my Galaxy S. That is very useful.

In a conclusion, that is very standard HTC　phone, but it has an attractive price tag.

New Android Dev Phone - Nexus One

admin — Mon, 09 Aug 2010 13:38:43 +0000

Google stated Nexus One will be their new standard dev phone. The price is good too, $529. Moreover, it will have Android 2.2(you need to download the update after the device is switched on). That is not bad at all. If I had not bought my Galaxy S, I would consider this option.
