Android Chrome - No Flash

Another hit for Adobe Flash after the annoncement that Microsoft will be plugin free

http://www.appleinsider.com/articles/11/09/15/microsoft_to_jettison_adobe_flash_with_plug_in_free_browsing_in_windows_8_metro_ie10.html

Now this is Google response... It looks like it is not going to take long for Adobe to be force to license it's RTMP and RTMFP framework for Android to keep up with Server side Video Streaming...

Google (NASDAQ:GOOG) introduced a beta version of its Chrome browser for its Android smartphone operating system. Chrome for Android Beta offers many of the same features as its desktop counterpart, but is not compatible with browser plug-ins or Adobe Flash technology. Chrome for Android Beta also is only available for tablets and handsets running Android 4.0, Ice Cream Sandwich.


Watch a video about Chrome for Android

Perhaps the main difference between Android's existing browser and Chrome for Android is the ability for users to port bookmarks and saved tabs from their desktop Chrome Web browser to their Chrome Android browser. Synced devices will also see the same autocomplete suggestions shown on the desktop.

Also, Chrome's tabs have been redesigned to fit on smaller screens. Users can swipe their devices to switch between tabs.

On the developer side, Chrome for Android introduces remote debugging via Chrome Developer Tools, allowing developers to debug profile Web pages and Web apps via mobile.

"With hardware-accelerated canvas, overflow scroll support, strong HTML5 video support, and new capabilities such as Indexed DB, WebWorkers and Web Sockets, Chrome for Android is a solid platform for developing web content on mobile devices," wrote Arnaud Weber, engineering manager at Chrome on the Chromium blog.

Google touts Chrome for Android as being as fast as its desktop counterpart.

"When searching, your top search results are loaded in the background as you type so pages appear instantly," wrote Sundar Pichai, SVP of Chrome and apps, on the Google Mobile Blog.

Create Bootable USB Windows 7

bootable USB guide, here we assume that you are using either Vista or Windows 7 to create a bootable USB.

1. Insert your USB (4GB+ preferable) stick to the system and backup all the data from the USB as we are going to format the USB to make it as bootable.

2. Open elevated Command Prompt. To do this, type in CMD in Start menu search field and hit Ctrl + Shift + Enter. Alternatively, navigate to Start > All programs >Accessories > right click on Command Prompt and select run as administrator.

3. When the Command Prompt opens, enter the following command:

DISKPART and hit enter.

LIST DISK and hit enter.

Once you enter the LIST DISK command, it will show the disk number of your USB drive. In the below image my USB drive disk no is Disk 1.

4. In this step you need to enter all the below commands one by one and hit enter. As these commands are self explanatory, you can easily guess what these commands do.

SELECT DISK 1 (Replace DISK 1 with your disk number)

CLEAN

CREATE PARTITION PRIMARY

SELECT PARTITION 1

ACTIVE

FORMAT FS=NTFS

(Format process may take few seconds)
ASSIGN

EXIT

Don’t close the command prompt as we need to execute one more command at the next step. Just minimize it.

5. Insert your Windows DVD in the optical drive and note down the drive letter of the optical drive and USB media. Here I use “D” as my optical (DVD) drive letter and “G” as my USB drive letter.

6. Go back to command prompt and execute the following commands:

6.1. Change directory to the DVD’s boot directory where bootsect lives:
d:
cd d:\boot

6.2. Use bootsect to set the USB as a bootable NTFS drive prepared for a Vista/7 image. I’m assuming that your USB flash drive has been labeled disk G:\ by the computer:
bootsect /nt60 g:

(Where “G” is your USB drive letter)

7. Copy Windows DVD contents to USB.

You are done with your bootable USB. You can now use this bootable USB as bootable DVD on any computer that comes with USB boot feature (most of the current motherboards support this feature).

Note that this bootable USB guide will not work if you are trying to make a bootable USB on XP computer.

Illusion

If your brain works normally

This is another example of an amazing illusion!!! The last sentence is so true.

If your eyes follow the movement of the rotating pink dot, the dots will remain only one color, pink.

However if you stare at the black '+ ' in the center, the moving dot turns to green.
Now, concentrate on the black ' + ' in the center of the picture. After a short period, all the pink dots will slowly disappear, and you will see only a single green dot rotating.

It's amazing how our brain works. There really is no green dot, and the pink ones really don't disappear. This should be proof enough, we don't always see what we think we see.

Eclipse & Tomcat - Create a Webapp - Hello World Tutorial

Directory Structure under: C:\xampp\tomcat\bin\webapps\mytomcat-eclipse-helloworld-scratch List of Directories: \WEB-INF \WEB-INF\lib \WEB-INF\src \WEB-INF\src\java \WEB-INF\src\myeclipse \WEB-INF\classes \pages List of files: \index.jsp \pages \pages\myhelloworld_bean.jsp \pages\myhelloworld_jstl.jsp \WEB-INF\web.xml \WEB-INF\lib\jstl.jar - copy this file. \WEB-INF\lib\standard.jar - copy this file. \WEB-INF\src\myeclipse\MyHelloWorldBean.java \WEB-INF\src\myeclipse\MyHelloWorldServlet.java

1 Download and Install Eclipse
Eclipse IDE for Java Developers

2 Download and Install XAMPP to its default location

XAMPP comes really handy with

Apache 2.2.21

MySQL 5.5.16

PHP 5.3.8

phpMyAdmin 3.4.5

FileZilla FTP Server 0.9.39

Tomcat 7.0.21 (with mod_proxy_ajp as connector)

3 Download Eclipse Tomcat Launcher plugin

At the time of this article tomcatPluginV33.zip

Extract the archive tomcatPluginV33.zip under C:\eclipse\plugins this should create a sub folder com.sysdeo.eclipse.tomcat_3.3.0

4 Set JAVA_HOME to C:\Program Files\Java

5 Set JRE_HOME to C:\Program Files\Java\jre6

6 Let's get started

To give you the big picture, in the steps below, you will use Eclipse to
create the following directory structure and files.

This examples Tomcat "webapps" directory is located at:

C:\xampp\tomcat\bin\webapps

 

7 Eclipse - Create a Java Project

8 Launch Eclipse

9 Tomcat Plugin

The Sysdeo Tomcat Plugin is our best friend. After you have installed it, you will notice these buttons and menues in your IDE.

The left button starts Tomcat, the middle button stops it, the right button restarts Tomcat. Right now, they won't work if you press them. To enable them, you first need to configure a few things. Go to the menu "Window-> Preferences" there, you will see this dialogue box.

Configure Tomcat Plugin

Windows-->Preferences-->Tomcat

Now you need to go to the menu item "Tomcat" and select your Tomcat version. At the time of writing that would be the 7.x version. Now we adjust the field "Tomcat Home" to point to the install directory that we selected before at install time. The Sysdeo plugin now knows where to look for the server.xml file and automatically assumes the standard path to look for the file. Eclipse is now able to manage this configuration file, i.e. add a new <context> for a new application

Browse for tomcat home and select tomcat version

Click on JVM settings and add JVM Parameters

-Xmx2000M

-Xms1000M

-XX:MaxPermSize=128m

Now we are ready to test start our Tomcat server. Click on the start button in the Tomcat menu and watch the console output. If Tomcat boots up without any stacktraces open your browser, and try to open the following address http://localhost:8080/ . If you see an image

that is similar, to the one below everything is working okay

• 10 File, New, Project, Java Project, Next


• 11 Project Name: mytomcat-eclipse-helloworld-scratch


• 12 UnCheck - Use default location.


• 13 Click "Browse" and navigate to the Tomcat webapps"
  directory (ex: C:\xampp\tomcat\bin\webapps\webapps).


• 14 This is a little tricky so follow closely.  We want to create a
  new directory.
  
  
  
  • Note:  The "webapps" directory should be selected.
  
  
  • Click "Make New Folder"
  
  
  • In the browse window list, you should be able replace the words "New
    Folder" with: mytomcat-eclipse-helloworld-scratch
    
    Note:  If you can't, in the browse window scroll to the "New
    Folder" and right click, choose "Rename" and change the folder name to
    mytomcat-eclipse-helloworld-scratch
  
  
  • Click "OK".
  
  
  • Check the value of "Location:" to make sure you have selected the
    correct folder.
    
    Location should now show: C:\Tomcat\Tomcat6.0\webapps\mytomcat-eclipse-helloworld-scratch
  
  
  • Click "Next" to go to the "Java Settings" screen.
  
  
  
  


• 15 Source Folder
  
  
  
  • Click "Create new source folder".
    
    Folder name: WEB-INF/src
    
    Click "Finish"
  
  
  • Right click on "src" and choose "Remove from Build Path". 
    Later you will delete the folder.
    
    (Note: We just created the src file in a directory that web users
    can't directly get to: WEB-INF/src)
  
  
  
  


• 16 Output Folder
  
  
  
  • Change the "Default output folder" to: mytomcat-eclipse-helloworld-scratch/WEB-INF/classes
    
    (Note: Currently the default will be:
    mytomcat-eclipse-helloworld-scratch/bin)
  
  
  
  


• 17 Click "Finish"


• 18 In the "Package Explorer" right click on "src" and choose delete.

19 Eclipse - Build Path - add the Tomcat lib jars files.

• Right click on the project.


• Click "Build Path", "Configure Build Path", then
  click the tab "Libraries"


• Check to see if "JRE System Library"
  is listed.  If not complete the next steps in this bullet.
  
  Click "Add Library", "JRE System Library",
  "Next", "Finish".
  
  Note: Under the tab "Order and Export" this lib file should be directly
  under the WEB-INF/src directory.
  
  You can't compile .java files without this library!!!


• Click "Add External JARs"


• Browse to the Tomcat common library directory.
  
  Ex: C:\xampp\tomcat\lib


• Select all of the JAR files (Ctrl-A), then click "Open".


• Click "OK" to leave the "Java Build Path" screen.

20 Create the "WEB-INF\lib" Folder

• Right click on "WEB-INF", "New", "Folder". 


• Folder name: lib


• Click "Finish"


• Library files - for this project we will be using 2 .jar files:
  standard.jar & jstl.jar. 
  
  These 2 jar files need to reside in: webapps\mytomcat-eclipse-helloworld\WEB-INF\lib
  
  
  
  • 
    mytomcat-eclipse-helloworld-scratch-lib.zip - download and extract this
    zip file into the new "lib" directory you just created.
    
    Note:  If you downloaded the files in this tutorial you will have this
    file in the directory:
    
    Pathname: tomcat\tutorial_tomcat_eclipse\webapps\mytomcat-eclipse-helloworld-scratch-lib.zip
    
    (Note: These lib files came from the Apache JSTL project called
    "standard".)
  
  
  • If you don't place the files properly in the lib directory you will get
    compile errors etc...
  
  
  
  

21 Create the "WEB-INF\src\myeclipse" Package

• Right click on "WEB-INF/src" (not
  "WEB-INF"), "New", "Package".

  File name: web.xml


• web.xml -
  copy this content into the file.  Right click on the filename, open
  with, Text Editor.  If you open with the XML editor you can't copy and
  paste.  After you copy-n-paste, then open with "XML Editor".


• Notice the 2 tags: <servlet> & <servlet-mapping>.  This is planning
  for the .java servlet file we will create.

24 Create the "index.jsp" file

• Right click on "mytomcat-eclipse-helloworld-scratch", "New", "File". 
  File name: index.jsp


• index.jsp -
  copy this content into the file. (Warning:
  If the server & browser doesn't show this file as a Text file then do a
  view source so you can copy-n-paste.)


• Note:
  
  
  • This JSP has just HTML tags.

25 Create the "MyHelloWorldBean.java" Java source file.

• Right click on "myeclipse"
  under the directory "WEB-INF/src", "New", "Class". 
  
  
  Name: MyHelloWorldBean
  
  Click "Finish"
