I think that you misunderstood.
Predicate logic is merely the fundamental of the query mechanism.
It has nothing to do with physical representation.
However, in practice, triples are used to store the knowledges, as in
prolog, decl, RDF etc. Triples, in a way, are EAV models (entity,
attribute, values). Sometimes it may be represented as
target>, or action
Declarative Programming is not a new thing, and declarative / procedural
programming are conceptually different. To mix them together in one language
like Scala, is not necessarily a good thing, because it will only create
conceptual confusion and implementation nightmare (anyone has experience
with Lisp / Prolog would know what I am talking about).
The cleaner solution is to incorporate declarative features at the meta
level for a procedural language. Probably they should work on something

haha, love it Foxman, you hit the nail onto the head.
我觉得其实computing 40多年以来,最好的还是good old c programming. Java也不错
。但scala学习一下不错,不知道将来是否会有市场。
我曾今学过Prolog, 觉得和AI相关的东西太深的都是忽悠。工业界和现实当中,最可靠
最好的还是扎扎实实的procedural programming. 加点儿Object oriented也就不错了
。
Prolog syntax and all recursion based. Very difficult to pick up.
Good candidate for building large system with excellent support for
multipcore programming.

evaluate(X,'-',Y,Z):- Z is X-Y.

一位美国CS写的,各位大拿如何看?
The Languages
C++ is well-suited for large projects because it has an object-oriented
structure. People can collaborate on one program by breaking it up into
parts and having a small group or even one individual work on each part. The
object-oriented structure also allows code to be reused a lot, which can
cut down development time. C++ is also a fairly efficient language -
although many C programmers will disagree.
C is a popular language, especially in game programming, becau... 阅读全帖
P松不P松的,老板给钱,PROLOG咱也不是没些过。
I tell you something, I just like Okeydos, they say OK they do it.
You know what, the contra converse , is that, they can not do it they are
not
Okeydo. But not, vice versa.

An EPSI file will contain a line starting %%BeginPreview: in the DSC prolog.
The preview can either be stripped out from epsi by some scripts. google is

[April 13, 2000] SML-DEV's Minimal XML. Don Park recently announced the availability of a
Minimal XML specification and a Java Minimal XML parser, with performance test utilities. Basically,
Minimal XML is XML without: Attributes, CDATA Sections, Comments, Document Type Declarations,
Empty-Element Tags, Entity References, Mixed Contents, Predefined Entities, Processing Instructions,
Prolog, and XML Declaration. This work is part of the SML-DEV project. SML-DEV is "a group of ove
Based on my personal experience, construction management definitely offers
an opportunity to get to know different phases of construction projects,
from pre-con to close out. Job market is not that bad for construction
management, especially for Project Controls (cost and schedule control).
If you decide to choose CM, I would strongly recommend to learn to use the
following software:
P5e/P3
Expedition/prolog

In addition, a summer intern is very important to find the full time job.

I was searching for pricing on some receivers and found this Pioneer Elite
VSX-31 on Walmart for $298.98. I had no idea that Walmart carried the Elite
line but then again, this is the only model i could find on their site. I
searched the webs but did find anything cheaper from a reliable known source
that had it brand new. I thought this was a pretty good price so here you
go
