TOP TEN WAYS TO MAKE YOUR BOSS THINK YOU'RE STILL USING MICROSOFT PRODUCTS
  WHEN YOU'VE ALREADY SWITCHED TO LINUX

  10. Don't get too much under budget or you might arouse suspicion.
      Perhaps you can channel a few thousand dollars into travel
      allowances or a lunch fund.
   9. Reboot your servers unnecessarily every few days. If users lose
      work tell them they should have kept a copy on their PC.      
   8. Whenever new security vulnerabilities appear, don't download the
      fix immediately. Instead, complain loudly about it for weeks and
      tell everyone you're waiting for the next service pack CD
      to arrive in the mail.
   7. Fake your downtimes.
   6. Place a ridiculously low connection limit on your web server.
      When this limit is reached, serve a page saying that the server
      is overloaded and tell people to try again later. Tell marketing
      that this is a sign of your site's popularity.
   5. Remove all mention of Linux from your login banners. Microsoft
      do this to their Linux boxes and you can too!
   4. Maintain a list of 'unsupported' file formats and network
      protocols. When customers ask if you support XYZ and it's on
      your list, tell them 'No!'; you may have to lie. Randomly
      regenerate this list every few weeks.
   3. Cover your desk in glossy brochures for badly named and way
      overpriced software that does very little. Continue allocating
      hundreds of dollars to each of these products long after you've
      replaced them with trivial shell scripts. If you manage it right,
      this practice alone can fund your collection of French antiques
      or low-Earth-orbit satellites. 
   2. Regularly demand overpowered hardware for trivial services.
      Demand high-end Pentium-II's for small internal mail and
      intranet services. Continue to run everything off a single 486,
      and stash all the new machines in an unused room. You can use
      them to earn yourself some extra cash rendering feature films
      in your spare time.

   AND THE NUMBER ONE WAY TO MAKE YOUR BOSS THINK YOU'RE USING MS
     WHEN YOU'VE ALREADY SWITCHED TO LINUX:
   1. Carry a bucket of sand with you everywhere you go. Whenever
      your boss sees you, make sure your head is firmly buried in
      the sand. If you feel the need to communicate, talk through
      your arse.
