Fast Git clone using shallow cloning

If you want to get a read only copy of a Git repository quickly you can do a shallow clone. To make a shallow clone use argument --depth 1 along with git command line version.

    git clone https://code.google.com/p/selenium/  --depth 1
   
When doing a shallow clone with depth of 1, it tells Git to fetch only latest revision of a repository. Normal clone fetches entire history of a Git repository. As per Git documentation, you cannot clone or fetch from it, nor push from nor into it.

Shallow clone is useful when you have a slow network connection or you want to save on the network usage.

Multi Tenant applications using PostgreSQL Row Level Security

 PostgreSQL supports Row Level Security (RLS) so that applications can restrict who can see which records in a table either based in DB user name or based on Connection session variable. This feature can be used to implement discriminator based multi tenant where records for multiple customers are present in single table. This blog explains steps for implementation https://www.crunchydata.com/blog/row-level-security-for-tenants-in-postgres Advantage of this approach is that its easy to implement and day to day application development activities dont have to bother about breaking multi tenancy because code for applying discriminator is implemented at a framework that obtains connection from connection pool. Application developers dont have to modify individual SQL statement or even pass around tenant_id as a parameter in method calls. Good thing about RLS is that RLS policy can be applied to specific Roles in Postgres and these roles should be used by application connections wh...

Recovering Dell Laptop Windows OS using factory image from Linux bootable USB drive

I used Linux booted from a USB drive to restore Dell Windows 7 factory image on Inspiron 1545 when Windows 7 stopped booting and F8 key stopped working. This was done using Linux equivalent of Imagex command and used dell factory.wim file. Credits goes to - https://www.dell.com/community/Windows-General/Restore-from-dell-recovery-partition-with-Imagex-Solved/td-p/4083636 Software used 1, PuppyLinux BionicPup32 8.0 (Ubuntu Bionic 32 bit) Downloaded as ISO image from their website. It is good to use any other popular distros like Ubuntu. 2, When using PuppyLinux, download Devx package which has GCC compiler for the corresponding PuppyLinux distribution. ( http://wikka.puppylinux.com/devx ). When using a full fledged distribution, this step may not be necessary. 3, USB pen drive or any flash storage. I used SD memory card because my laptop will not boot from a pendrive. 3, unetbootin-windows-661.exe 4, Wimlib 1.13.1 - downloaded source because a binary distributio...
