Last week I presented at J-Spring 2008. It was one of the first times I presented to such a large group of unknowns. The room wasn’t packed, but still quite full. Afterwards I heard the head count was over 70 people attending my session. Good to see that many people interested in ANTLR. I was in the before last round of sessions and not everyone of the 1000 people attending was on the premises anymore. So all in all. I think I did good by at least attracting 10% of those people still there.

My presentation went very smooth. In 45 minutes I crammed 42 slides, 3 short demo’s and a 5 minute Q&A.

I did fumble on one single thing.

ANTLR does allow more than 2 nodes with the same root node in a tree.

It’s all supported in the tree grammar syntax. The grammar I demoed was indeed binary, I thought the question was about that fact, while in hindsight I realised the person was asking if ANTLR support AST’s with more than 2 child nodes on a node.

I’ve just put some final touches to a presentation and demo I’m giving on ANTLR v3. On april 16th I will be presenting at the Dutch NL-JUG J-Spring conference. It’s a Dutch conference focussed on all things Java.

Hope to see you there, and if not, my employer is probably going to post my slides very soon somewhere linked of of this page.

Oh my, that Redmond OS called Vista is truly a freakish beast. Today my girlfriends laptop refused to connect to my new Apple Time Capsule. I had my Time Capsule configured for personal WPA/WPA2 over 802.11 b/g/n. My girlfriends Vista laptop was able to connect and authenticate, but was unable to get a DHCP lease, it ended up with one of those 169.xxx.xxx.xxx addresses. The steps to remedy the problem were really bizarre.

I reconfigured my Time Capsule to use no wireless security. I then connected her Vista laptop, it could get a DHCP lease. I re-enabled all security. Adjusted the network settings on her laptop to use WPA2. And it works flawlessly, I can even do ipconfig /renew from a command prompt.

Vista: The dumbest operating system ever if you ask me.
