Well the time has come for me (Michael) to say goodbye – to Red Hat. I must turn into the force, just as yoda did. I will of course remain a community member – using and developing drools. It has been a blast working on this stuff fulltime for the last few years – andRead more →
Enterprise Space Invaders !
Here is a a great article on using declarative rules (drools in this case) in game programming (versus loops within loops).
Some Tohu videos
Tohu is the project which ads Q&A and “smart form” intelligence on top of drools (and provides a very nice CSS stylable and embeddable jquery based ajax front end as well). (see project page here). Some interesting demo videos made by solnet here explaining how it works: Example 2 (spreadsheet to define Q&A) Example 1Read more →

Recently Opened Clicking on the recently opened item will open a listing of all items you have “recently” opened (it tracks a few hundred itemsRead more →
Update on the “Advisor” smart forms tool…
Some people have asked about a tool mentioned some time back for creating smart forms made (which was being done by Solnet). This is being prepared to be open sourced, and will have a section on jboss.org where you can find it/download it. Status update from Derek: Just a brief update: There is a proposedRead more →
Real time chat…
And now for something completely different… A recent feature request was for a discussion/comment feature for files in Guvnor: The comments are below the “documentation” section (and of course optional) (and there is an Atom feed to them). An interesting addition was using a “backchannel” type connection that is kept open from the browser toRead more →
Loop detection ideas…
A common problem with writing systems in rules, is when you are mutating data (modifying working memory in any way) it is possible to have rules activate themselves over and over, and cause a non terminating loop (also known as an Infinite Loop ;). Now we all know we can’t know for sure (yet) thatRead more →
Frozen areas to make GUI templates…
A feature recently checked in to trunk: an optional attribute to tell the editor to “freeze” parts of a rule. This is useful if you want to give some users access to some rules – but not change the structure (remove bits, add bits, general mayhem). Users with sufficient permissions can edit options, and canRead more →
A take on Drools Boot Camp 09…
These are my notes and pictures – I am sure others will have notes and pictures to post (if you do have pictures, feel free to email them to me and I will share them here, or links to Flickr or whatever…). First day, “state of the union”: We had a few kind-of presentations eachRead more →
