Ever since I upgraded to Snow Leopard 10.6.1, my MacBook Pro startup and shutdown was much slower than before. I searched for a quite a while on forums to find the solution, but nobody seemed to know a solution. I finally figured out what it was. It seems that somehow the ownership of my startup volume's root directory (/) wasn't assigned to the root account anymore, but to my account instead. This made the kernel prelinking fail since it requires that root is the owner. This is how you solve this after launching the Terminal app: sudo chown root:admin /You'll have to enter your password after the first command. Hope this helps someone, since it was really frustrating to have these slower startup/shutdown times for me. |

Terracotta 3.1GA was released a few days ago and sports some interesting new features that are specifically geared towards clustering Hibernate second level caches. I decided to create a series of video tutorials and presentations about Terracotta's new clustered caching capabilities and will demonstrate most of this from our Examinator reference application. The first video highlights how to install, setup and use Examinator as a basis for the next videos. Enjoy! |

I picked music back up after a loooong hiatus of 7 years. I decided to evolve together with the world and to broadcast myself Did the first one last night. The song is "All The Kings Horses" from Robert Plant and the Strange Sensation. When I heard it playing last afternoon from my iTunes collection, I couldn't help picking up my guitar to figure out the chords and such. This recording is the result of a couple of hours searching and rehearsing. I'm considering adding it to a concert repertoire I'm preparing, as one of the few cover songs. Anyways, my YouTube channel is located at http://www.youtube.com/gbevin and I'll be posting new entries as I learn and compose songs. Hope you enjoy it, and if you don't, still be nice |

Hi everyone, Calling all hands on deck here, we're participating in a music contest and they finally opened internet voting. If you can't see the 'vote' button it's because they tie individual votes to IP addresses and someone behind the same firewall has already voted. Please vote for my band Flytecase at http://vote.flytecase.beThanks a lot for your support, Geert |

The Open Session in View pattern is very popular when Hibernate is used in a web application. This allows you to safely use managed entities when your view is being rendered. At Terracotta, we're currently researching what other patterns are popular for Hibernate and how people apply them. One that I'm in particular looking into is the Extended Session pattern for long running conversations. This allows you to disconnect a Hibernate session in between requests and to store it in the HTTP session in the meantime. I'd like to know who's using the extended session pattern and what you use it for. To understand more about this, I developed a small example application to get a feel for the advantages, the benefits, the gotchas and the surprises. The application can be found below, it is inspired by snippets from Hibernate tutorials and example applications: http://svn.terracotta.org/svn/forge/projects/hibernate-disconnected/trunk/ The example uses only servlets, filters and Hibernate. It is a webapp that allows you to create events and add people to it over different requests. When an event has been created with all the relevant people, it can be committed in one step. The intermediate state is kept within the managed entities and the Hibernate session until it's flushed. This is what I found worth mentioning:
