ROWID messed up by VACUUM

Issue:

ROWIDs in a SQLite table has been changed after executed a VACUUM command.

Reason:

VACUUM command rebuilds the entire database, and recreates rowid for all tables.

Solution:

Although query by ROWID could be fast, but it should not be used as an external key.
Use an explicits integer primary key in the tables.
```
CREATE TABLE t(x INTEGER PRIMARY KEY ASC, y, z);
```

VACUUMing SQLite

Issue:

SQLite database file size keep increasing.
SQLite database file size not reduced after deleted tables or rows.

Reason:

In SQLite, when an object (table, index, or trigger) is dropped from the database, it leaves behind empty space. This makes the database file larger than it needs to be, but can speed up INSERT operations. Over time, INSERT and DELETE operations can leave the database file structure fragmented, which slows down disk access to the database contents.

Solution:

Use VACUUM command rebuilds the entire database; or
enable auto vacuum in the database, use command pragma auto_vacuum.

AIR 2 Namespace

Issue:
Error message below appear when running an AIR 2 application.
An ActionScript error has occurred:

VerifyError: Error #1014: Class IIMEClient could not be found.

at flash.utils::Timer/_timerDispatch()
at flash.utils::Timer/tick()

Reason:
You must update your application descriptor file to the 2.0 namespace in order to access the new AIR 2 APIs and behavior. If your application does not require the new AIR 2 APIs and behavior, you are not required to update the namespace from 1.x based namespace.

Solution:
To update the namespace, change the xmlns attribute in your application descriptor to: http://ns.adobe.com/air/application/2.0

Open your application descriptor file (-app.xml), edit the 2nd line.

<application xmlns="http://ns.adobe.com/air/application/1.5.3">

Change the value for xmlns to http://ns.adobe.com/air/application/2.0

<application xmlns="http://ns.adobe.com/air/application/2.0">

Hello, Google Chrome World! Log for my first Google Chrome extension test.

Google Chrome now has extensions, and GG now want to have create some Google Chrome extensions ^^

By referring to the Getting Started tutorial and samples on Google Code Labs, I’ve created my first Google Chrome “Hello, World!” extension. It was much easier than expected.

Steps:

Create a folder called mygc_ext01.

Create a text file called manifest.json inside mygc_ext01 folder, contains code:

{
  "name": "My First Extension",
  "version": "1.0",
  "description": "The first extension that I made.",
  "browser_action": {
    "default_icon": "icon.png"
  },
  "permissions": [
    "http://api.flickr.com/"
  ]
}

Prepare an PNG icon called icon.png put into the same folder.
I’ve tested it with .ico file in my Windows 7, it works.
If we use a .ico icon, we should also change the value for default_icon to our .ico filename (e.g. filename.ico).
Now load the extension into Google Chrome.
Click on Tools menu and choose Extensions.
Enable Developer Mode.
Click Load unpacked extension…
Browse for the mygc_ext01 folder, and press OK.
My icon successfully displayed as an extension button on Google Chrome .

Edit manifest.json, add popup parameter below default_icon

...
  "browser_action": {
    "default_icon": "icon.png",
    "popup": "mypage.html"
  },
...

Create a new file called “mypage.html” put into the same folder.
Display something in the html page body.
On Google Chrome Extensions Developer Mode, press the Reload link behind My First Extension. And now if I click on my extension button, mypage.html will be displayed in a popup.

I’m planning to create some Google Chrome extension, but for now still need to sort my bunch of idea.

Below is an working example mygc_ext01 where mypage.html contains code to retrieve and display some picture from flickr.
