 MJ12Net is a site that I use as a repository for all of my notes. Whenever I learn something new I'll post it here. I create scripts to help me automate things that would otherwise have to be done manually. I'm learning some really cool stuff so I will take time throughout my day from now on to update the site just like a wiki. Thanks for stopping by everybody.My Statcounter tells me you guys come here from all over the world. I get most of my traffic from the United States, India, Germany, the United Kingdom, and Canada in that order. I get people from all over the world. By far my most popular page is the System Administrator Interview Cheat Sheet. I am sorry to say that it is starting to get out of date. But it still has some handy stuff on it. If any of you guys are like me and want to chat please drop me a line. Thanks All, Brian |
