find . -type d -exec chmod 755 {} \;
This will recursively search your directory tree (starting at dir ‘dot’) and chmod 755 all directories only.
Similarly, the following will chmod all files only (and ignore the directories):
find . -type f -exec chmod 644 {} \;
$ export http_proxy=http://myuname:mypass@myproxy:myport
$ sudo apt-get update

What do “read”/”write”/”execute” mean?
r – Read permission. Whether the file may be read. In the case of a
directory, this would mean the ability to list the contents of the
directory.
w – Write permission. Whether the file may be written to or modified. For
a directory, this defines whether you can make any changes to the contents
of the directory. If write permission is not set then you will not be able
to delete, rename or create a file.
x – Execute permission. Whether the file may be executed. In the case of a
directory, this attribute decides whether you have permission to enter,
run a search through that directory or execute some program from that
directory.
Examples of and related commands
chmod u-x,g+w,o+rw somefile
chmod xyz filename
(r = 4; w = 2; x = 1)
chown new-owner somefile
chgrp new-grp somefile
This applies to both AIR and Flex project, in Flex SDK 3.3:
// Application.application refers to the top level application.
// But be aware that it's typed to Object as opposed to Application.
// According to Flex team, it's for the purpose of fast compilation and
// being able to access properties/methods in the <Script> of their
// <Application> without having to cast it to their application's real type.
// So this means you can get:
// var stuff:SomeStuff = Application.application.getStuff();
// but you would have to access the real application each time by saying
// Application.application. Or you can do it this way:
var app:MySubclassedApplication = mx.core.Application.application as
MySubclassedApplication;
// UI components with id names are automatically declared as public
var contactList: ContactList = app.contactList;
// as long as you've declared them as public in your <Script>.:)
var dou:Dug = app.dug;
var stuff:SomeStuff = app.getStuff();
Documentation. Note when you are using SWFLoader to load a module into the main application, you can reference your main application as parentApplication.
1. Download JFv1.51_CRB43-US.zip (file size 36,614 kb).
2. Rename it to Update.zip and copy to the root of your SD card.
3. Shut down G1.
4. Reboot G1 by holding down Power+Home buttons at the same time, which should bring up the bootloader.
5. Bring out the key board, first Alt+L to display log, then Alt+S to apply patch; this should apply the update.
6. Once done, G1 prompts you to reboot.
7. Per my personal experience, I got stuck on the Android logo (the 3D chrome logo), which froze at the animation loop. What I did was a) Took out the battery and reboot, which doesn’t seem to fix the problem; b) Reboot the second time by going to 3, 4 again. On the bootloader screen, Alt+W to wipe data and reset to factory default.
8. Power up G1 once done. That’s it.
At least it worked for me:)
Running the examples that come with the SDK in Eclipse
Eclipse->Package Explorer->Right click->New ->Android Project->Contents->Create project from existing source->Location>Navigate to
<directory_of_your_android_SDK>/platforms/android-1.5/samples/ApiDemos>OK
Eclipse will populate other setting values such as “Project name” and “Build Target” for you.:)
Local resource page (index.html)
<directory_of_your_android_SDK>/docs/index.html
just in case you don’t have/just lost/are having creeping internet but are desperate to look up the documentation to get something done ASAP so that you can go home;)
Go to Package Explorer -> Right click your Android project ->Run As->Run Configurations.
Under Android Application on the left column, select your project -> on the right column, where you see Android | Target | Common tabs ->
Select Target -> on the bottom “Additional Emulator Command Line Options”->
-http-proxy http://wwwgateProxy.com:1080 -debug-proxy http://wwwgateProxy.com:1080
->Run/Close.
In a recent prototyping project, I attempted to simulate “shake” gestures in a desktop AIR application, i.e., using mouse cursor to simulate a hand grabbing some object on the screen…
Anyhow. I found out that Flash Player can send out the mouseMove event must faster than it can update the screen. In the case you want to keep track of the simulated gestural motion, you would want to track the mouse cursor position on the stage, instead of the display object the mouse cursor is dragging. This is because when you drag the object to the point Flash Player cannot keep up with, the redaw will then not necessarily reflect the real positional changes of it in between the frames.
Take a look here. Right click to for the code. Also note that when directly register Application.application as the currentTarget we seem to get smoother tracking than if we registered the display object, like so:
mButton.addEventListener(MouseEvent.MOUSE_MOVE, mButton_handleMouseMove);/** you got more stripped out points than if you do this:
addEventListener(MouseEvent.MOUSE_MOVE, mButton_handleMouseMove);// this is btter.*/
I find that MVC is much easier to understand both at the conceptual level and at the implementation level if you think about it from the perspective of how you communicate with the Model.
<mx:TextInput id="mTxt" change="mVO.txtValue = mTxt.htmlText;"/>In Flex 3, when you bind a model to a control, it is one-way communication, meaning the control will reflect the change whenever there is one in the model; but the control would not be able to change the model. That’s why we need to wire through the change listener to make this happen.
The output is hooked up by setter methods in the Model. Whenever you detect some changes that are historical, you would notify your listeners.
[Bindable]
public function set myValue(v:int):void
{
_myValue = v;
notifyListeners();
}
In ActionScript 3, we normally implement “notifyListeners” by way of dispatchEvent. Your client listens to the event and updates the View by querying the changes from the Model. You may want to have different types of events so that your listeners can respond differently. For example, you normally would invalidate properties of your component and regenerate all the renderers when the data provider has changed, besides doing other updates; and you don’t want to do this kind of heavy-lifting each time when changes occur on the “less important” members of the Model.
public var chatModel:ChatModel = new ChatModel();
In another console window, you want to access the same model, like so:
private var chatModel:ChatModel = Application.application.chatModel;
A lightweight plugin for Eclipse. Works good for me on Flex Builder 3 (v3.0.1.2x).
