Select the Adobe Flash Player in viewer configuration
Run –> Run configurations –> Select your Launch Configuration file –> “Start” tab –> Viewer configuration.

Make sure you point out to the Debug version of the player in Windows –> Preferences –> FDT –> Tools –> Flash –> Flash Player. In my case the path is C:\Program Files\Adobe\Adobe Flash CS6\Players\Debug\FlashPlayerDebugger.exe but you should adjust this to wherever your Debug player resides.

Evaluation of different Android debugging tools

2013-06-13T21:21:00.001+05:30

Objective : Evaluation of different Android debugging tools and selecting one which can be used to debug our apps on mobile and tabs.

Analysis : We have experimented with different debugging tools present for android debugging and following is the analysis:

1) ADB :

Limitation : Only applicable for chrome browser issues. Not suitable for debugging issues with default browser on mob or tab.

Remarks : Very tricky installation and can take hours of time. But we will document the steps we took for installation which may help. (A separate blog post will be dedicated to this).

Evaluated platform : Samsung s2 mobile and google nexus 7

2) JSConsole :

Limitation : Only suitable to debug javascript related issues.

Remarks : Simple installation and easy to use.

Evaluated platform : Samsung s2 mobile and google nexus 7

3) Firebug Lite :

Limitation :

a) Very inconsistent behavior shown. Sometimes the firebug frame is visible, sometimes its not.

b) Need usb support on the device (mob or tablet) to attach a mouse for smoothly navigating through DOM shown in the firebug toolbar.

Remarks : Simple installation but very difficult to debug.

Evaluated platform : Samsung s2 mobile and google nexus 7

4) Weinre :

Limitation :

1) Javascript issues can be debug only using console.log but not using breakpoint techniques.

2) Server is tightly bound with IP, so there needs to be static ip where the weinre server can be run.

3) The web page that needs to be debug needs to include a javascript file which needs to be loaded from the server url hence same limitation as 1

4) The network tab does not display any information about the request/response cycle.

Remarks : Simple installation and can be used to debug DOM /CSS related issues.

Evaluated platform : Samsung s2 mobile.

5) Other Techniques :

The other techniques like About:debug are also less developer friendly and lack community support.

I like the "4. USB Remote-Debugging" but "This is only possible with Google Chrome, not the default browser. (Chrome is available for Android 4+)."

http://android.stackexchange.com/questions/5999/android-browsers-aboutdebug-what-do-those-settings-do

Conclusion : Weinre is the most suitable tool for debugging in default android/stock browser. However, before we jump to debug any issue we should test if the issue is reproducible in chrome so that we can make use of adb remote debugging which provides the ability to debug in chrome inspector on the desktop and can save plenty of time.

Environment : Windows 7

These steps can be followed to setup weinre which can be used for mobile debugging. Links are mentioned for further assistance.

1) Install node (preferably v0.8.19 or above as the subsequent steps may fail with other versions)

https://github.com/joyent/node/wiki/Installation

2) Open command prompt and check if node is installed by executing the command “node -v” (without inverted commas). If setup correctly, it will output version of the node that was installed.

Tips : Add to your path environment variable if its not updated immediately after node installation.

3) Open command prompt and check if npm is installed by executing the command “npm -v”. (npm gets installed along with node)

4) Open command prompt and Install weinre using npm (node package manager).

npm –g install weinre

5) Start weinre server by following these steps:

a) Modify the file attached and replace the boundHost parameter to your ip

b) Create a directory named “.weinre” in your home directory (execute the following command on the command prompt to find it)

echo %HOMEPATH%

c) Create a file server.properties with the contents from the file attached with the email.

d) Execute the command

start weinre

6) Copy following line in your web page html.

7) Load the web page in your device. This will set your device as debugging target.

8) Open browser and go to the address

<your-ip>:8000/client

Note : This the window where we can see debug the page loaded in the target device.

Oracle 10g installation struggle

2012-01-04T15:28:00.006+05:30

Inspiration: Oracle 10g did not work for me on Ubuntu 11.10, Ubuntu 10.10, Oracle Linux x86_64. I spent 3 weeks trying different distros and ended up doing the following steps which saved me from wasting any further time and I was able to work without any problems. So here's to those three weeks :)

Step1: Take backup of your data if you have any of the linux distros mentioned above.

Step2: Skip this step if you already have Ubuntu 9.1. Install Ubuntu 9.1 (karmic).

Step3: Install oracle 10g as a root user. Problem becoming root? solution follows :

sudo passwd root

su root

Download debian package from Oracle 10g from oracle website (western european).

Double click on it and you will be done.

Install the oracle-xe-client if you want one!

Upgrade your ubuntu to any of the newer version if you want fancy UI and more security.

Any questions? would love to reply to your precious comments :)

Postgres error: psql: FATAL: Ident authentication failed for user “postgres”

2011-11-29T17:14:00.000+05:30

I am in a hurry so i will just post the solution this time.

CAREFUL Ctrl+c and Ctrl+v users: Remove the angle brackets in names

———————————————————————————

***Restart the postgres server after finishing the changes***

user@desktop: /etc/init.d/postgresql-8.4 restart

———————————————————————————–

user@desktop: psql -Upostgres

FATAL: Ident authentication failed for user “postgres”

user@desktop: emacs /etc/postgresql/8.4/main/pg_hba.conf

user@desktop: Replace the phrase Ident with trust

Additional details:

If it complains FATAL: password authentication failed for user “”

su root

su postgres

ALTER USER WITH PASSWORD ‘’;

Drop in your qs and i will edit the post a/c.
