Tsunayoshi writes "My son volunteered me to give a presentation on what I do for a living for career day at his elementary school. I need to come up with a roughly 20-minute presentation to be given to 4-5 different classrooms. I am a systems administrator, primarily Unix/Linux and enterprise NAS/SAN storage, working for an aerospace company. I was thinking something along the lines of explaining how some everyday things they experience (websites, telephone systems, etc.) all depend on servers, and those servers are maintained by systems administrators. I was also going to talk about what I do specifically, which is maintain the computer systems that allow the really smart rocket scientists to get things into space. Am I on the right track? Can anyone suggest some good (and cheap/easy to make) visual aids?"

wetdogjp writes "I recently became a high school teacher, and I've inherited three classes with no textbooks! While two of my classes are introductory in nature, one for computers in general and the other for networking, the third class should prepare juniors and seniors to enter the workforce and start a career in computers. We have some older textbooks by Heathkit available, but the newest of them are four years old. Do Slashdotters have any favorite textbooks that can help kids on their way to becoming junior sysadmins, programmers, networking professionals, etc.? Would you suggest books to prepare students to take certification tests such as A+, Network+, or others? Any textbooks we use would need to cover quite a breadth of material, such as PC hardware, operating systems, networking, security, and more."
An experimental gas turbine simulator equipped with an ultralow-emissions combustion technology called LSI has been tested successfully using pure hydrogen as a fuel -- a milestone that indicates a potential to help eliminate millions of tons of carbon dioxide and thousands of tons of NOx from power plants each year.
