This week I'll be in Amsterdam attending and speaking at Euro OSCON. I'll be running a session on DTrace on Thursday at 1:30. For the uninitiated, DTrace is the systemic observability framework in OpenSolaris that allows for tracing of the kernel and applications on production systems. At OSCON in Portland, Bryan and Wez extended DTrace into php (it already worked on C/C++ and Java); since then, the DTrace community has extended DTrace into Ruby and Perl -- we'll see if we can come up with something new this week.
I've had a bit of a chance to explore Amsterdam a bit and it's spectacular.
My California-thinned blood won't let me forgo a comment on the rather cold weather, but my Northeastern upbringing won't let me complain too loudly.
