DevNexus: human friendly conference March 10-11 in Atlanta

I will be speaking at DevNexus. This small conference is a spin off the Atlanta Java User Group.

Here are a few things I like about the conference personally:

• There is around 10 presentations over two days, so you will be able to see all / most of them.
• The price is very reasonable ($150 for early birds), $185 regular price.
• The size is reasonable, so interacting with speakers is natural.
• Atlanta in March is very nice.
• ahem, I will be speaking there, ahem.

I will personally speak about our experience in scaling Hibernate in big environments and how SaaS vendors can face the challenge. I will also discuss Hibernate Shards and Hibernate Search with regard to scalability. And there are nine other speakers at the conference, so check their website.

How to install Git and git-svn on Mac OS X

It's hard to find good Google links for installing git-svn on Mac OS X. Here is my piece.

• Install port: download it at http://darwinports.com and run the installer
• run sudo port install subversion-perlbindings (it takes a while as the installer download the internet)
• run sudo port install git-core +svn (don't forget +svn or you will have to uninstall git-core and reinstall it)

You are ready to use git svn command. git-svn does not work but git svn does: that's because git-svn is not in your PATH. If you want to make git-svn work, add /opt/local/libexex/git-core to it (thanks Randall for the tip).

From there, have a look at http://viget.com/extend/effectively-using-git-with-subversion for a quick tutorial.

Answering questions at JavaRanch + free books

I am doing a session on Hibernate Search all this week at JavaRanch. Manning will give away free books of Hibernate Search in Action for the occasion.

If you have questions on Hibernate Search, express yourself :)

JBoss AS 5 is out, Hibernate Search 3.1, Devoxx is warming up and

Great news this week:

• JBoss AS 5 is out. Congratulations to Dimitris and the many people in and out of JBoss who contributed to it.


• Hibernate Search 3.1 is out. A lot of good stuffs like performance improvements at indexing and querying time and some cool new features like the analyzer declaration framework (allowing declarative phonetic, synonym, n-gram indexing and searches)


• Devoxx is very close. Come see the JBoss folks and topics and come to the Seam meetup after the BOF of course :)

Also, on the Bean Validation (JSR 303) side, I am finalizing the last changes in the spec for the public draft. We made a lot of progress in the last two weeks on various subjects including type-safe groups and JPA / JSF / EE integration (with the finalized draft, I will officially contact the EE expert group). Stay tuned, hopefully the draft should be out in a week or two.

Finally, Hibernate Search in Action is supposed to be released in final PDF monday (still not believing in it till I see that one ;) ).

Great week on my side. See you at Devoxx for a drink or two.

Hibernate Search 3.1 RefCard

DZone has a nice Hibernate Search 3.1 6-pages ref card. It is packed with:

• The list of annotations and their descriptions
• Hibernate Search's main APIs
• Lucene's most useful query types
• Quick examples involving mappings and API usage (including the new analyzer declaration framework)

It's free but you need to register.

Speaking of the devil. John and I have given back our last edits for Hibernate Search in Action. So we are still on target for releasing the book in december. I personally still can't believe I am done, so I will play the St Thomas and will wait till I can touch the paper :)

You can get the paper book at Amazon or on the Manning website. Manning also offers the PDF version.

Book review and NHibernate Search

Ayende, one of the active bees behind the NHibernate portfolio, has a nice review of Hibernate Search in Action on his blog.

By the way, Ayende has ported Hibernate Search to .net : NHibernate.Search. I don't think there is documentation specific to the project but the Hibernate Search documentation is just as useful.

I don't know Ayende personally, but I can only admire someone that blogs more that I can tweet and still have a full time job :)
