Even though I can't blog about my job or the tools I use there, I can post and blog about OSS or my hobbies/passions.

I recent made a detail technical post on a forum covering a well known subject that newbies still ask questions about. I had to piece the solution to my particular problem from hours of research. I covered the situation from a personal aspect with details of the problem, tools used and costs. If it helps someone resolve a similar problem in less time, then it's worthwhile.
