Devel::NYTProf 3.0 is out, more mindblowing than ever

Go run to the [announcement about Devel::NYTProf v3.0](http://blog.timbunce.org/2009/12/24/nytprof-v3-worth-the-wait/). Marvel at the code profiling goodness.
Highlights include:
* Ability to profile opcodes, which means…
* NYTProf can now profile slow regular expressions
* More detailed stats on BEGIN blocks
* Treemap of subroutines
* Tracking of which subs called which other subs
* Graphing of sub calls
* Improved report output
* Ability to merge profile runs, such as when a process spawns other processes like mod_perl code does.
Already I have found that my regular expression compilation is taking 6% of the runtime in my sample runs in [ack](http://betterthangrep.com). I had no idea.
Just amazing. Go try it now, and buy Tim Bunce and the other contributors a beer.

Advent calendars galore

*By Matt Follett*
It’s the time of year for Advent Calendars and it looks like the Perl community isn’t disappointing this year.
[Perl Advent Calendar](http://perladvent.pm.org/2009/)
> The first day talks about using Package::Alias to alias Mouse to Moose.
[RJBS Advent Calendar](http://advent.rjbs.manxome.org/)
> Ricardo Signes’ calendar to showcase things he has been working on. His first entry is about Sub::Exporter which looks very powerful.
[Catalyst Advent Calendar](http://www.catalystframework.org/calendar/2009)
[Perl 6 Advent Calendar](http://perl6advent.wordpress.com/)
> This one starts off with setting up Rakudo, so it requires very little prior knowledge.
[SysAdvent](http://sysadvent.blogspot.com/)
> Tips for system administrators
All of these have RSS feeds, so they’ll be easy to follow. Have fun!
