This is about the relationship between technology and astronomy, and in particular about people in astronomy getting into the hi-tech world. These people might be graduate students looking for jobs, they might be fully fledged academics wanting to exploit their know-how. Whichever it is, it is essential to understand the differences between these two worlds and especially to understand that the hi-tech world only wants you for what you can bring to the table. So welcome to “the hi-tech party”.
