AHCI(Advanced Host Controller Interface) mode brings 3 main advantages:

1. Supports NCQ (Native Command Queuing) allowing SATA drives to accept more than one command at a time and dynamically reorder the commands for maximum efficiency.
2. Supports hot plugging of devices.
3. Supports staggered spin ups of multiple hard drives at boot time

When ever we develop ASP.NET application, we keep our entire environmental specific settings into web.config file. Based on where we deploy the application (Dev, Test, Prod), we will comment out other environments which is a manually process. Personally I prefer different web.config files for different environments and based on the Build option you select it should dynamically create the appropriate web.config file for that environment.

Recently my wife asked me what is the difference between UNIX and Linux. Basically I dont know much about these operating systems becauseI always work with windows operating systems.

Most of the people browse the internet every day and some sites are reliable and some or not. Eventhough we browse good sites, some sites as 3rd party Ads which install some crap/malware in our computer and says some infection or virus were found in our computer. It asks you to purchase the software to clean up the crap/malware. So many times it happened to my wife computer and good thing is i always take image of her PC so that when ever it infected with virus, i reimage back.
