It's shift F3 and shows as a pound sign when I type the message but it's
become a hash when the message comes back.  But I am typing this on a

Modern UK keyboards use  for #.

When I started programming, they used  and didn't have a $ 
symbol ...

"Mathematicians prove theories correct, Scientists prove theories

Computer Science is in the business of proving things correct, therefore
it can't be science :-( Oh - and you need the correct definition of a
theory before you can understand the above definition - "A theory is
something which is not yet proven". (And for those who wonder at that
definition, seeing as we seem to believe many scientific theories as
"proven", scientific theories are believed precisely because we have
been UNABLE to prove them wrong. Mind you, I can't off-hand recall *any*
scientific theories currently that haven't - at least in the fine detail
- been proven wrong.)


Another fine point here as there is another definition that is more
applicable to the term "mathematical theory."  I sometimes poke or
"tease" relational theorists (do I know how to have fun or what?) by
using your above def of theory, but if you look at something like
http://www.answers.com/theory&r=67 and take the third def, that is
what is intended when discussing what is considered a mathematical
"theory" -- A set of theorems that constitute a systematic view of a
branch of mathematics.


But I think, even there, it's still unproven (and therefore a theory by 
my definition), because as soon as it's proven it becomes a theorem in 
its own right ("theorem" - that which trivially follows from the chosen 
axioms).


So, when Date or Codd uses the term "relational theory" they do not
mean that it is something that is not yet proven, they are referring
to doing pure mathematics.  --dawn


Which is why we shouldn't be using it in real life :-)

Re: [U2] [UV] Conversion code for week number

Hi Mark,

The U2 conversion code source code is not public so we can only guess. 
The method used by OpenQM was recently changed to correct problems with 
dates way back in history and is essentially as follows. It sounds 
complex but it is mostly just a series of division operations.


1.  Add 718430 to the day number. This gives a datum of 1 January 0001 
to simplify things. (QM documents that it doesn't support BC dates and 
that we don't allow for the calendar changes in 1752 or 1583 depending 
on where you live).


Or 1919 :-) I always like to point out that 2000 was the first "century 
year" since 1600 when Europe actually agreed whether it was a leap year 
or not.


2. Divide by 146097 to work out how many 400 year cycles we have 
completed. This allows for the complications of leap year calculations.


I'd've thought you could handle the calendar change dead easy here... 
just have a cut-off date (user selectable :-) for the switch between 
calendars, and if it's before that date you apply a constant, while if 
it's after you apply this 400 correction. At the cost of one extra IF, 
you've now got accurate dates right back to start of the modern 
calendar.

Wol

2007-07-22 Thread MAJ Programming 
Thanks Martin.

I've heard of several algorhythms similar to this and was curious what Pick
used. Every time I tried my own expressions I either came up short on
covering all dates or it was way too time consuming. Of course I wasn't
writing it in assembler or other lower (faster) code either.

Thanks.

[U2] Unidata 7.1 / RedBack 4.2.6 / Connections dropping?

2007-07-22 Thread Andy Pflueger 

Hi all,

We've recently implemented a workaround on our Solaris 9 (production)
box to restartrgw on a daily basis...immediately following our backup
script that essentially runs dbpause, breaks mirror, dbresume, backups
the broken mirrored disk, and mirror resync. In addition, we're also
running UD w/ RFS enabled. The problems that we are facing (hence why
the workaround was implemented to restartrgw) was that RedBack would
intermittently drop connections if it goes for 3-4 days or so without
being restarted. By dropping connections I'm referring to anytime our
apps that use RedBack (very few anymore that we're developing our apps
with UniObjects) would result in unsuccessful db connection attempts.
Restartrgw seems to solve the immediate issue as does restartrgw on a
daily basis.

Has anybody out there running a similar setup encountered such
situations and is 'restartrgw' ultimately the best solution here? We
are, in fact, also running REDBACK.GC via a process that runs nightly
to keep garbage collection clean so I don't believe it's GC that is
part of the problem. Not sure if this makes sense or not, but it seems
to have started soon as we turned on RFS.

TIA,
Andy Pflueger
