I can't believe I never thought about how useful map and grep would be
in the debugger.

That is really slick. ;-)

We're back in our OLD ROOM NUMBER - 276

I've been out of town for two weeks and too lazy to write the git workshop scenarios; and Stephen got called out of state for a few days. So, the git workshop has been pushed to next month.

We'll use tomorrow night's meeting to prep for the git workshop and/or whatever else people want to chat about / present. Perhaps early retirement to SIG-BEER/COFFEE?   :)  

See you there!

Oh!   :)

 

Searching the XML::Twig POD for "att" the very first hit says, quote:

 

   Other useful methods include:

 

      att: "$elt->{'att'}->{'foo'}" return the "foo" attribute for an
element,

 

So for all these years I've assumed there was no public accessor method
for attributes.   :)

 

Live and learn!  Thanks!

 

I find the POD confusing. ->{'att'}  is not a *method* at all, so why he
calls that a "useful method" is beyond me.  -shrug-

Works:

 

my $att = $pack->{att}->{postingRhythm}

 

 

Works better:

 

my $att = $pack->att("postingRhythm");

Re:

I prefer 

 

   if ( $in_string =~ /<(HotelCode|mfResort)>$code/mgi ) {

 

Or a full XML parse.   :)

I put IRC links on our homepage about a year ago. Other than my coworkers at Omni, I don't recall if anyone has dropped by. irc.perl.org #perl-help, #catalyst, #moose are my most-used channels. Saves me many hours of banging my forehead.

Also, irc.freenode.net #omaha.dev is for Omaha developers, of any language.  :)

Has anybody in Omaha done any Perl6? The email below is an interesting idea, but I only have 3 hours of experience with Perl6, so I probably shouldn't lead such a meeting.

---

I've launched my own consulting company. If you have any overflow work, keep me ("us") in mind.  :)

   http://mutationgrid.com
   Software / database consulting

So now my company will be sponsoring food at the meetings where we don't have another sponsor lined up. My wife's checkbook is off the hook.  :)

---

I've been pondering moving our website from MediaWiki (which almost no one ever uses) to a hosted Linux virtual server where everyone that shows up to any meeting can have root access (sudoers), and the website is driven by whatever technologies people want to install on that box. So lots of live demos and sandbox areas built into our website server / community dev server. linode.com is $20/month, which Mutation Grid could sponsor if people would use it. And/or we could start a $12/year group membership fee to support the linode? I'm all about more participation, buy-in from our members... Thoughts?

---

Eeek, I really need to flush out the git workshop scenarios some more. Stephan's fled the state, so you're stuck with me as git poobah. Should be OK, only with far less dictatorial confidence.   :)

OK, I've probably stirred enough pots for one email. Signing off.   :)
