[rules-dev] Want to host IntelliFest (previously RuleFest)?

Mark Proctor — 2012-05-25T04:21:46

IntelliFest (previously RuleFest) is currently trying to find premises 
on the west coast of USA, with near by accomodation, to host 150 people 
for 4 days. Interested in hosting?

[rules-dev] 2 very useful github tips

Edson Tirelli — 2012-05-24T13:54:16

   Was watching a presentation yesterday from Zack Holman (< at >holman) and he
presented 2 very useful tricks on github:

* on any page in a repository, press "t" on your keyboard and start typing
the name of a file and it will find the file for you. Same as ctrl+t/ctrl+r
on Eclipse. I use this all the time. Press "?" for a list of all keyboard
shortcuts.

* on a diff/commit page, add "?w=1" at the end of the URL to make the diff
ignore whitespaces. Very useful for those commits where people are using a
different code format.

[rules-dev] Functional Programming in Drools

Mario Fusco — 2012-05-23T07:32:13

Hi all,

similarly to what Edson did with his Event Sequencing specs, I modified and
enriched my draft proposal about Functional Programming in Drools:

https://community.jboss.org/wiki/FunctionalProgrammingInDrools

and opened a JIRA ticket to gather all the comments and suggestions related
to it:

https://issues.jboss.org/browse/JBRULES-3516

I just started working on the development of the features listed in that
document and at the moment I only have a first working implementation of
what described in the "Higher-Order functions" section.

Thanks for your feedbacks,
Mario

[rules-dev] Event Abstraction,Event Sequencing and Pattern repetition

Edson Tirelli — 2012-05-22T19:43:01

   All,

   For the next Drools release we intend to add support to event
abstraction, event sequencing, pattern repetition and related features. A
draft proposal can be found in the following link:

https://community.jboss.org/wiki/EventSequencing

   I opened a JIRA to centralize feedback for future reference:

https://issues.jboss.org/browse/JBRULES-3514

   Feedback is welcome on the above ticket. I would like to minimize e-mail
feedback as that ends up lost in time.

   Individual features will be implemented in sub-tickets of the above
master ticket.

   I am starting to refine the draft and will start the design asap, so the
sooner you send me feedback, the more likely it will be included in the
final release.

   Thanks,
      Edson

Re: [rules-dev] Drools 5.4.0.Final released

Matthew Versaggi — 2012-05-16T08:14:19

Hi Mark,

I got excited about the possibilities so I tried to port Drools over about
6 months ago and got hung up for all of the reasons you have mentioned....

I would like to point out (as I experiment w/the AlphaPad Android 4 Tablet
-> wholesale from China) that the 'new' up and coming Android tablets
really 'do' have plenty of processing power and capacity to handle the Rete
Algorithm.

I have ported Prolog to the Android platform (B&N Color Nook) and as long
as it's loaded 'properly' it runs  plenty fast.

I also suspect that the corporate market would have some hidden (but quite
profitable) uses for Drools on the Android Tablet Platform, as I think the
flood of Cheap high quality Tablets that I think China will flood the US
market with, is inevitable. I live in the Netherlands (X-Pat from Chicago),
so we get to see some of these trends before they hit the mainland.

Just food for thought, and congrats on a great product! :-)

-matt

This is a channel for those developing drools itself, the lists page 
clearly specifies for you to join the USER mailing list
http://www.jboss.org/drools/lists

That book is many years old, guvnor has changed a lot since then, there 
is no updated version for that book title. I suggest you look at the 
documentation that comes with the release you are using.

Please ask any further questions on the USER mailing list.

[rules-dev] can't put the formula in Guvnor 5.4

zeeshan khan — 2012-05-15T10:52:42

Hi Team !

           Since yesterday only I started learning Drools with the help of
Google and *JBOSS DROOLS BUSINESS RULES pdf file*. I faced many problems to
understand the concept but now its going smooth. But the problem is
the *version
of PDF file of the book* and the *Govener version*. *Its quite different*.
 I request you all to please provide me the latest version of PDF as I am
unable to find on net. The problem I am facing is to put the formula as
given in the screen shot in the book.
           I am unable to put the *formula* as described in JBOSS DROOLS
BUSINESS RULES pdf file on page no. 102.....the formula is *salesValue-10
as the box is not capable of taking cahracters. *It is taking only integer.

Thanks in Advance for all the help and material !!!!

Re: [rules-dev] Drools 5.4.0.Final released

Mark Proctor — 2012-05-14T20:24:27

currently drools relies on runtime code generation, and our architecture 
is built around that. I think it may run already if you use pure MVEL 
with 5.4 - or atleast a few tweaks and it shoud run. 1) probably stop 
the JIT kicking in to ASM bytecode statements. 2) I think I remember 
some classloader problem, android needs parent classloader. The other 
option is we pre-generate all our generated bytecode and put it in a jar 
so it can be resolved when needed.

I've not prioritised it, because our Rete algorithm can be too eager for 
mobile enviornments. However I almost have lazy rete working, that 
merges the benefits of Rete and Leaps; the resulting algorithm is ideal 
for mobile enviornments. Once I get that working, I'll be more keen to 
accelerate our mobile efforts.

Is there any talk about porting Drools to Android 4 by chance?

[rules-dev] Drools 5.4: Artificial Intelligence, A Little History

please vote up:

-----copied from website link-----
As part of the 5.4 release, going out the door as we speak, I updated 
the intro docs. I have tried to give a wider understanding of the field 
and scope of work. Here is a copy. I'll try and improve the sections 
over future releases, I ran out of time and the later sections are 
little rushed and thin. I'm not the best of writers, so please have 
patience, all contributions welcome :)


      *A Little History*

Over the last few decades artificial intelligence (AI) became an 
unpopular term, with the well know "AI Winter" 
<http://en.wikipedia.org/wiki/AI_winter>. There were large boasts from 
scientists and engineers looking for funding, that never lived up to 
expectations along with many failed projects. Thinking Machines

[rules-dev] api's, factories and services

Mark Proctor — 2012-03-01T11:22:54

Just a reminder when doing api's

Stage interfaces in internal-api and make sure you do factories for 
them, almost never expose "new" constructors to users. We provide both 
static factories and a service registry, and we ideally should continue 
to support both. i.e. we have
KnowledgeBuilderFactory (static method factory, actually wraps below)
KnowledgeBuilderFactoryService (singleton service)

static example:
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder()

singleton service  exmaple:
KnowledgeBuilderFactoryService kbuilderfs = 
ServiceRegistry.getInstance().get( KnowledgeBuilderFactoryService.class )
KnowledgeBuilder kbuilder = kbuilderfs .newKnowledgeBuilder()

All of our factory services should be registered in 
org.drools.util.ServiceRegistryImpl, this has delegation to say OSGi if 
it exists (via the service locator pattern). So we become much more 
friendly to OSGi or other container environments that are service 
locator oriented.

"new" should almost never be used, apart
