As a sysadmin, there are many repetitive tasks that one does during the day. I try to live by the sysadmin creed that if you have to do a task more than twice it is time to automate.
Recently, I have needed to convert Kilobytes into Megabytes. Now, I know the short cut is just divide by 1000. But, that is only just a short cut. Really the magic number is 1024. There are a lot of converters on the Internet. I use many of them. Because I have never been good at bookmarking or the bookmark is on another workstation, I have to continually search for that converter that I have used in the past.
Now I just need to put this page on an internal web server or on my local workstation and I can call it up when ever I need.
