When installing or upgrading operating systems you may come across terms like cumulative update or slipstream installation. So what is this ‘slipstream’ installation? Slipstream install files are those installation packs/ISO files in which the install-software and service pack are integrated. You do not need to install the OS first and then upgrade the service pack level. One installation process will give you the operating system updated to the indicated service pack level.
Needless to say, the first release version (RTM) of the software would not make sense to be a slipstream package. Once the service packs come out, you will find options for slipstream packages or just the service packs.
For example, when SQL2008R2 came out, users could install the software on their system. When SQL2008R2 SP1 came out later, users who already had SQL2008R2 installed could just download SP1 and upgrade their server. If there was a system that did not have SQL2008R2 (after the release of SP1), users had the option to grab a slipstream install and get SQL2008R2 SP1 in one install process.
Happy new year to all my readers. May this new year bring peace, joy, and prosperity to all.
In Windows 7 and newer operating systems, the TRIM command can be used to maximize the life and performance of Solid State Drives (SSDs). Using this command is known as trimming the SSDs. This command is useful as SSDs operate differently (internally) from HDDs (Hard Disk Drives). The TRIM command will notify the SSD on which blocks no longer contain data that needs to be persisted, and a few low level operations later, the data on these blocks can be safely deleted.
In windows, to see if you have trimming enabled, run the following command on the command line:
fsutil behavior query DisableDeleteNotify
If the result is a 0, it means that TRIM is enabled. A 1 indicates that TRIM is not enabled. To enable trimming, run the command below:
fsutil behavior set DisableDeleteNotify 0
This is not a SQL post, as usually seen on this blog. I am thinking of adding some colour to my blog by posting non-SQL items once in a while. This is an experiment to check out the duality of SQL blog readers.
Now here is the pitch: Open a bank account with ING direct with a balance of $100 or more, and receive a additional bonus of $25 when you use the following orange key: 29959316S1
If you are like me and like to invest or see our money grow, then this is a quick and worry-free way to make $25. The bank in question is ING Canada and I have been banking with them for close to a decade.
