Last Night

2001-02-27 Thread Dave Cross


So, was that fun or what?

Thanks to everyone who turned up and a special thanks for everyone
who made it possible - Damian (obviously), Merijn Broeren, Mike Davis,
Paul Mison and Andy Williams (for paying for the hall) and the 
unnameable organisation who brought Damian to London in the first 
place.

Our next meeting is on Thursday. I know you might be suffering from
too much Perl Mongers, but please bear in mind that we need to spend
at least £250 in this pub the Dave Cantrell has booked for us, so every
little helps :)

Oh, and I've had a quick look at Bleach.pm and Morse.pm and wish to
raise a bug against Morse.pm. It doesn't actually convert stuff to
Morse Code, just to something that _looks_ like Morse Code.

See you Thursday,

Dave...

p.s. And don't get me started on my nightmare journey. I thought that
all night buses went thru Trafalgar Sq - the N19 doesn't :(

Another bug,  when a script gets bleached anything preceding the use Bleach

A *few* tweaks to the core?  Come on now, you'd have to make the core
grok multiple dimensions!  (... and that would be about as easy as
building an infinite improbrability drive...)

But I suppose you might argue that the core already _spans_ multiple
dimensions (everything does, until you look at it), so it wouldn't relly
need to understand this to make use of it.  So maybe it would just be a

We can reason that there is a Perl Core that spans multiple dimensions
so there must be a finite probability that there is one. Somewhere.
Possibly in a galaxy, far far away.

AIUI, square roots apply to numbers, so how can you have a square root of
something that isn't a number, like an operator?  You may as well say that
you can take the square root of anything - like the square root of equals,
or the square root of a pony.

Calling that thing the square root of an operator is a bit misleading to

I have to disagree. Part of the power of mathematics comes from
looking at something, seeing that it works like something else,
proving that, and then continuing to call it something else because
that then gives you all the stuff you know about the 'something else'.

And 'square root' is just an operation on something. If you can
meaningfully do that operation to something that isn't a number (and
in the maths associated with QM, obviously, you can) then go for it.

Apparently SRN stands for "Square Root of Not", so they're not hiding
it too much.

http://www.qtc.ecs.soton.ac.uk/lecture1/lecture1d.html
is interesting.

I agree about generalisation. I think it's perfectly reasonable
to call such an operator the "square root of not" in context;
as long as you understand that by the same definition, adding
one is the "square root" of adding two ;-)

I've also found

 "The Square Root of NOT"

which seems to be a good non-experts introduction to *real* QC.

I remember him mentioning that there was an implementation of shor's
algorithm in Quantum::Entanglement.

 I'm iller!  I'm using Q::S in production code, cos it's easier to read than
 what I was doing previously.  We'll see what a performance hit I get when
 I run it over a real dataset.
 
 A slightly related question - I remember Damian having a slide with his
 version of Shor's algorithm, which I can't find anywhere in the perldoc and
 which I can't for the life of me remember.  I think at the time that my
 brain was trying to escape through my ears.  Can anyone remember it?  The
 only version I can find online is in the Q::E module, and it ain't what
 I remember.

I just bought a Mars bar, and it's

They already did that on IRC!  Keep up, that man!

 Actually some of the quantum computing people believe that the
 parallel calculations before they collapse to the result are _really_
 taking place in alternative worlds.

I still think they're actually orthogonal universes, but that's mere
quibbling.

I'm trying to cut down on IRC. It's becoming too distracting.

   Hi,
  
   Given the following lvalue subroutine
  
 sub mysub : lvalue {

   is there any way for mysub() to be able to determine that it
   was called in an lvalue context?
 
 No. If you need to know that sort of thing, you kind of have to tie
 the $value that you're going to return, and use that as a proxy for
 the *actual* value. If you're called in an lvalue context then the tied
 object is going to have its STORE method called...
 

 I'm new to the discussion of Perl6, so are there any discussions around
 providing operators such as wantlvalue and wantvoid
 to perform similar queries to wantarray?


wantarray will tell you if you are in a void context - IIRC correctly it
returns undef in void context and 0 in scalar context I also recall there
being a little controversy over this recently in p5p ...
