  Vesselin Bontchev reported in May 1990:


  The Dark Avenger virus.

  ======================


  - I found two new mutations of this virus. Well, maybe "mutations"

  is not the correct word. In the first of them, the first 16

  characters of the string "Eddie lives...  somewhere in time!"  were

  replaced with blanks.


  In the second example, all strings (the message above, the copyright

  message and the "Diana P."  string) were replaced with blanks.  -

  The author of the Dark Avenger virus (The bastard!  I still cannot

  determine who he is.) has released the source code of his virus.


  It is full with ironic comments about me.  Of course, now we have to

  expect lots of new, similar viruses to appear.  At least, this

  leaded to one good thing - the source helped me very much in

  disassembling the V2000 virus.  - I received a rather offensive

  anonymous letter from this person.  In it he claims to be also the

  author of both the V2000 (I trust this) and the Number of the Beast

  viruses (the latter is unlikely).

Evidence supporting quantum information processing in animals

              Evidence supporting quantum            information processing in animals                    James A. Donald                    1068 Fulton Av                    Sunnyvale, CA 94089-1505                    USA I show that quantum systems can rapidly solve some problems for which finite state machines require a non- polynomially large time. This class of problems is closely related to the class of problems that animals can solve rapidly and effortlessly, but are intractable for computers by all known algorithms. 1. Introduction      Animals, including very simple animals, can rapidly and effortlessly perceive objects, whereas computers take nonpolynomial time to do this by all known algorithms [1, 2, 3, 4, 5, 6]. Our persistent inability to emulate perception gives reason to doubt the current paradigm and to look for an alternative paradigm.      Penrose[7] and many others [8, 9, 10] argue from practical considerations, Godel's theorem, and

ARMIES OF CHAOS

                          ARMIES OF CHAOS -      Before anyone proposes more gun control, he or she should know  about a simple, deadly weapon 4 times as powerful as Dirty Harry's  legendary .44 Magnum -- and at least twice as concealable -- that  _can't_ controlled.        This simple, deadly weapon can be made by anyone -- even a  child -- with unpowered hand tools in an hour's time using $5 worth  of materials, most of which are available around the house anyway.   In traditional form it's reusable an unlimited number of times, and  modern plastics have rendered its disposable version electronically  undetectable.  You can clear a room with such a weapon (more of a  hand-held directional grenade than a gun -- sort of a recycleable  Claymore mine) and it's just one of hundreds of similar time-proven  designs.        Complete instructions for building this simple, deadly weapon  could be given in half the space I'm using here and not require a  single illustrat
