Greetings,

    I was talking to Steve Hardcastle-Kille the other day about the
prospects of X.500.  He relayed to me that he'd recently spoken to someone 
who had been gung-ho about the distributed directory, but who had "lost the
faith".  Well, that's funny I said, as I've recently been surprised by how
well it can work.

The basis for this belief is that I have added a new feature to the DE
interface (available as the PARADISE service) which allows for multiple
organisation searching, or power searching as someone has coined it.  This
allows you to search for Bloggs within a country, when you do not know the
organisation the person works for.  To be honest, I was surprised at how
well this type of search works - certainly surpised at how quickly I got
some results.  You certainly don't want to do this type
of multi-cast search for normal queries, but it seems to me to be a very
valuable facility when you really are stuck for the organisation name.  I
have been able to find all sorts of people who I previously had no way of
finding.

I certainly wouldn't pretend that the current approach is not without
scaling difficulties, but I believe it works well enough at the moment to
encourage people to use the Directory, when many are disuaded by the
decisions which are usually forced on users by the DIT hierarchy.

The software will be available as a package soon, both over the Quipu API
and over University of MIchigan's LDAP.  In the meantime, you can try the 
service on one of the PARADISE project's machines.  Do let me know what you 
think.

Paul:
   One of the primary problems I have with the X.500 standard, irrespective
of the various implementations, is that it locks the user into the X.500
namespace, and the user has to know a great deal about the layout of the 
namespace if she wants to issue more than local queries. So even the power
search option is not sufficient for Yellow Pages type queries, and I have some
*extreme* concerns about how this concept will scale. 

The Yellow Pages problem is actually extremely difficult to solve in X.500.
Either one has to munge the namespace to contain all the relevant attributes
for searching (as in @o=Internet@ou=K-12 Information) which is a horrible hack,
even if everything under this subtree uses aliases, it's still next to imposs-
ible to maintain, especially when the entry has been moved out from under
the alias. The other way is to create relevant subtrees under each 
organization's entry (for example, for K-12 Educators who work for IBM)
However, in either case, you are forcing the user to be aware of the
layout of the name space to get at the information they really want.

I think that the whois++ stuff solves these problems quite nicely, as many of
the solutions fall right out of the architecture.

Thanks to those of you who passed on comments or raised interesting points.
I'd likely to briefly address some of the issues raised.

Load: to be honest I don't have a lot of sympathy for DSAs.  With a few
honorable exceptions most people running DSAs have not been swamped with
queries.  Taken to an extreme, one could "defend" DSAs by providing DUAs of
such limited usefulness that users were discouraged from using X.500.  There 
must be better ways than this of denying service to avoid congestion.  

I don't believe in practice that users will want to "power search" very
often.  Even if it is surprisingly fast, it is still a lot slower than if
one can provide an organisation name match.  In the short term, of course
people will play.  Good for them, as I believe the more the Directory offers,
the more positively they will feel about the Directory.

Filters: there is room for experimentation / improvement here.  The filters
used when power searching are appreciably tighter than those used in DE's
normal search mode.  If anything they are now too restrictive, but I don't
want to loosen them up until I can analyse the effect of so-doing.

1. Nice feature, even if only for priving X.500 even in the current state is
    not that bad

2. I also share the DSA manager concern about load. However it is
     really nice to have a mean to check/measure the impact
     and thus to have figures to base our "policies"

3. reminder: even if a large majority of pilot participating DSAs
     are QUIPU, they are not 100%, and the interest/feasability
     must be considered with "heterogeneity" in mind
     (NOTA: this is not a criticism to Paul Barker; I know he is
      aware of that and takes it into account: just a reminder
      related to too QUIPU specific comments about memory size
      and TURBO-INDEX;
      However I am really interested in "generic" performance
      considerations.

I think it works great from a user's perspective!  As a DSA manager, however,
I am concerned about the load if this practice becomes widespread (and why
would I not want to use a 'power search', now that I know it exists :-)

Agreed; how many of use used the directory to see how many
Barker's/Letts'/Hawthornes's there were in the directory ? :-)

The load it places on the DSA depends upon several factors:
	1. Are the searches optimised
		- looking at the searches produced they are neatly optimised.
		looking for "r letts" produces a search of the form:
		(cn=r**)|(sn=letts) - very neat!

	2. Are attributes optimised, and the subtrees indexed ?
		- they search cn= , and sn= attributes; these are normally
		optimised.

	3. Is your DSA compiled with TURBO_INDEX defined
		- This speed searches by an order of magnitude if (1) and (2)
		is true; which it normally is.

	4. Do you have enough memory in your DSA ?
		- A much longer message will be posted on this. Our
		core-image has grown to 33MB; on a 24MB machine some searches
		take a considerable length of time.

Because of these factors, especially 1-3, the load isn't significant.

I am a Australian citizen currently living in the San Francisco Bay
area.

I have been researching the Mirage IIIO/D in service in the RAAF for
some years (most of which was done before moving here 12 months ago).
I wish to obtain accurate scale drawings of the Mirage for my
research. The type of drawings I require are more oriented towards the
structural aspects of the airframe. In particular, I'd like drawings
showing the airframe cross section at regular intervals along the
fuselage (say every couple of feet) or at each of the 30 or so frames
members along the fuselage's length.

I realize the information I'm searching for is quite exotic. My
primary interest is for large scale model building (don't worry folks,
I'm not planning on building a real one :-). Most of this information
should have been declassified when the Mirage was taken out of service.

I'm willing to pay for the duplication and postage of this information
should anyone have anything. May I also add that any other technical
information would be appreciated. I also have some information for
which a swap could be arranged.

As some of you may or may not realize, alot of this type of
information was burned by the Air Force when the Mirages were replaced
by the Hornets.  Although some of you may have opposing views, to me
this is historical sacrilege.

I'd be interesting in corresponding with anyone with similar interests
in this aircraft. Also, if any one has any ideas where such
information might be found, I'd greatly appreciate any help.
Regrettably, I'm not on NEWS so any correspondence would have to be via
normal email channels.

That's nothing!!! I've owned my 1979 Nissan 200B for five years and in that time
I've driven 140 000 of it's 261 000 (Yes, read the numbers, two-hundred and sixty
one thousand) kilometres and used 23.670 shitloads of fuel. (Question, how much is
a shitload!) and I do drive it to work, and home, and to Queensland and to Bathurst,
and....

I've owned my cheap and nasty vinyl  schoolbag (hang on, shouldn't this be in

foot, rail and air, and didn't use a drop of petrol... :-)

stuartb carries on with this pedantry...

I've owned my 1982 model Casio FX-100a since well, 1982 and it that time it has
done heaps of calculations, used not a drop of petrol. Last week I got the shits
with it because the batteries I did my HSC (1985) with ran out. Bummer!

However, it does imply the contrapositive:

not to mention the contraindecisive:

	"I think, therefore I might be confused"

and the postcontrapositive:

	"I stink, therefore I was",

According to the triple JJJ news,
video evidence provides incontravertible proof of a person commiting a crime.

Is this true ???

Should it be that anybody with high tech video equipment be able
to manufacture 'incontravertible evidence' ???

Of course, in the WA police case, the video was supplied by the police
themselves. It is usally used to provide a record of the people
in the police station, what they say and do, etc.
