My iPhone was a locked one with 3.1.3 upgrade. I jailbroke it using redsn0w-0.9.4(windows). There is a trick at this step while start cracking firmware 3.1.3, you need to point 3.1.2(iPhone1,2_3.1.2_7D11_Restore.ipsw) firmware path to break 3.1.3(iPhone1,2_3.1.3_7E18_Restore.ipsw) while selecting firmware on first screen of redsn0w. This works just perfectly.

The Future of Creative Advertisement

It was beyond my imagination to understand the new wave of advertisement that is taking shape right now. I have never thought how social media can be used in the media ads. This was clearly evident as I surfed the following two state of the technology ads:

Harley davidson

Both of these adds almost like websites with interactive video, games, photo and gallery. At the very same time these were seamlessly integrated with twitter and facebook. The huge number of hits that these ads gathered is evident of the fact that a revolution in the field of marketing is going to take place soon as the technologies are more available to achieve the same now.

I read this exiting story at google blog by Neal Mohan, Vice President of Product Management.

Database Migration from Postgres to SQL Server or any other DB to SQL Server

Upgrade to SQL Server 2000 and SQL Server 7.0

In order to migrate a database from POSTGRES to MS SQL Server use a very powerful set of tools called Data Transformation Services (DTS). These tools can help you perform these tasks in Microsoft SQL Server 2000. DTS can help you import, export, and/or transform data from various sources to single or multiple locations. Please refer to a very good illustrative article for all details at TechRepublic.

In order to migrate data from postgres please install an ODBC driver for postgres so that the DTS can communicate with the postgres. Once this is done use import/export or copy database wizard available in MS SQL Server. Create a DTS job on your MS SQL Server and schedule it using dtsrun.

Upgrade to SQL Server 2005

If you are migrating to SQL Server 2005 you can use Import/Export wizard provided by Integration Services package (SSIS) or even the Data Transformation Services (DTS).

In order to use SSIS you need to have SQL Server Business Intelligence Development Studio installed. A very nice tutorial that illustrates how to use the import/export on SSIS is available at Database Journal written by Gregory A. Larsen

If you are confused between DTS and SSIS please refer to a very good discussion on Simple Talk. Laso refer to MSDN for better details.

Good resource on Postgres.
