Fosdem 50 minute introduction into Drools

The Fosdem video is now up online. For anyone wanting an introduction into Drools, it's a good starting point.

There will be a youtube version posted later. Thanks to Heiko Rupp for making this video.

  1. Thanks for the link. But very irritating to watch the video when it constantly switches between showing the (dim) classroom and suddenly the code (on white background); and ofcourse, the "slow zoom in" of the code. arrrghh.

  2. If the video had shown Mark + the original slides, either Mark would not be visible and the slides were ok, or the slides were just white and Mark was ok.

    So I decided to sneak in the slides at the right point and otherwise have Mark talking.

    With the "zoom in" you mean this little moving, not the fade in? That is coming out of the fact that the aspect ratio of the slides and the original video is different. Cutting slides slide by slide to the right ratio is a pita (perhaps OOo could have done it automatically). But something to optimize for next time.

  3. Yes, as a whole, that was not a positive learning experience. The visuals were poor and the speaker needed to rush horribly. I am sure he understands the topics but maybe the goal should have been to teach others. I am off to search the web so I can get an introduction to Drools (something that this did not do well at all).

  4. Do we get to have the slides as promised 6 min into the video? I've used drools and still am having trouble following (since we don't actually see the information for long)

  6. Ok - thanks. Google didn't know. When asked about the above url, it told me about http://permalink.gmane.org/gmane.comp.java.drools.user/18103 (and that's all)

  7. This video was terrible, and the slides were not put in at the right time. You should have the slide up the entire time that he is explaining/pointing at the screen, otherwise it is impossible to see what he is saying. It is not important to see the speaker, it is only important to HEAR the speaker and SEE the screen. If you must cut to the speaker, only do it when he is not referring to the screen at all, which is only very brief periods as he switches to a new slide/topic. Please fix this so people can actually learn from this. Thank you.

  8. This is the most terrible cut I've ever seen, unbelievable! Could you recreate this video in a way that is shows the slides all the time,

    thanks

  9. Mark,

    Thanks for the presentation, you are cute and all, but it would be nice to have the slides up as the rest of the people posted.

    Thank you

  10. The video was kindly made by Heiko W. Rupp, in his own time, see first comment. i'm sure Heiko will take your comments onboard for future videos. For now you have the slides available in a separate download, so you can just look at this directly and ignore the video, other than using it as a prompt to know when to change slides.

  11. Heiko, thank you for doing the video. Suggestion for next time, please stay on the slides since the entire presentation is about that. Brief view of the speaker at the very beginning and end would suffice. But first and foremost, thank you.

  12. No need for that - just open up the slides at the same time. That way you can go back and forward as well when you can't quite follow.

    Much better than trying to find times in a video

  13. Thank you for doing the video. Please do not let some of the more negative comments keep you from doing more in the future.

  16. I'm still confused which url has the slide content.

    The athico link has three more video presentations , and then three more links buried at the bottom.

    Is the intention that the Fosdem2010 link cooresponds to the presentation above?

  17. Where is the link to the slides ?

  18. I'm still confused as to what problem Drools solves. I understand its a work flow engine but that video conveyed nothing. At least in the first 10 min because I couldn't watch anymore. I'm use to a teacher explaining the problem then showing how the tool can solve said problem. This guy just wanted to start fires in some rooms and turn on and off sprinklers/alarms. Are you guys joking? As someone said earlier, I now need to search on Google to find a real introduction to Drools. Mark, I can't understand how you actually stated "The Fosdem video is now up online. For anyone wanting an introduction into Drools, it's a good starting point." Good for who? Good for what?

  19. The talk was focused on Drools Expert, which is rule engine, not a workflow engine. Drools Flow does workfow, and I touched on it very briefly, as it was mostly out of scope of the talk due to time. I'll probably remove it completely from future Drools Expert talks. Drools Flow has now been deprecated as the technology was moved into jBPM.

    Rule engines are used for reactive monitoring situations, like alarms. They are used for validation and scoring - such as mortgage applications. They are used for tracking, such as logistics delivery. They are used for diagnostics.

  21. Hi,
    I'd like to suggest to Heiko W. Rupp, at least in the future, to just point the camera at the slides. For the narrator the voice would be enough.
    Also, I can find the slides online, but some pictures are lost. Any idea where to find a copy with all the pictures?
