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.
