Earlier this week, Microsoft made
Row-Level Security (RLS) available for SQL Database. This feature, which was
released as a preview in January, allows the customer to control who has access
to rows in their database table based on a user's characteristics such as
identity, role and execution context.
The concept is similar to having
all the data is in one table and then using a query with predicates to
decide what data is returned, the query doesn’t change only the values being
used in the where clause changes.
Dude, Where's my GUI - Windows Server 2012/R2
During one of my classes, a
student encountered an issue with his virtual machine (VM) which was running
Windows Server 2012. After attempting multiple solutions to fix the issue the
VM restarted but all that came up was the command prompt, the Server Manager
tool didn’t start, there was no task bar. Holy crap, we just lost our GUI!
Clone Virtual Disk Image (VDI) as a Virtual Hard Disk (VHD) file
Due to some laptop
issues I needed to move some virtual machines (VM) to my replacement machine
but this time I decided to run them on Hyper-V. Instead of trying to convert
the disk image files to VHD I decided that having a VDI and VHD copy for future
would be best. Virtual Box has a command-line interface called VBoxManage that
allows you to clone the hard disk image using the clonehd command.
