Meillo says, he uses vi for daily programming (german posting[1]).  An
  interesting aspect is the lack of syntax highlighting.

  Today, syntax highlighting feels like  an  essential  feature  of  any
  editor. In fact, I favour Vim over vi because of that.

  Meillos  point  is  that  the  lack of syntax highlighting can lead to
  better code quality. You, as a programmer, are more careful. You  take
  a closer look.

  Having  written  a  lot  of code in DOS and BIOS basic interpreters, I
  wonder: Do I really need syntax highlighting? Does it do any harm?  Am
  I careful enough with my code?

  About  a  year  ago,  I  stopped  using an alarm clock. For some weird
  reason, I have the ability to wake up  at  a  specific  time  --  even
  without an alarm clock.

  Only  recently  have  I  discovered how this works. And this discovery
  made me use an alarm clock again. It's trivial: I  regularly  wake  up
  during  the  night  and  check  the  time.  Of course, this results in
  reduced sleep quality. You never really *rest*. It's,  in  fact,  very
  stressful.

  When  you  use  an  alarm  clock,  you go to bed and don't worry about
  anything. You just sleep. The device takes care of waking you up.  You
  don't have to do that yourself.

  All the time, I thought that it's "healthy" not to use an alarm clock:
  If you can wake up "all by yourself", without any external  influence,
  then  surely  you  get  enough  rest  and sleep. Your body knows best,
  right?

  Well, yes. But the human body is also very powerful and robust and can
  survive under harsh conditions. It won't buckle down just because of a
  little sleep deprivation. It takes much more than that.  You'll  still
  *survive*.

  Your brain, on the other hand, will perform with reduced efficiency.
