Hello, I'm Tutelary. An edit you recently made to Operating Systems: Design and Implementation seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.
