I wrote about the first day of YAPC::EU 2012 yesterday and told you that the weather was really hot. Today is much cooler, only slightly above 30°C outside but in a building... without air conditioning... but with >400 people... you don't wanna know now.

There has been no summer in Germany. Few warm days, but not real hot - until last weekend. Today is very, very hot in Frankfurt, over 35°C and only one YAPC room has a slight touch of air conditioning and everybody is melting.
How to get 400 Perl-geeks in one building? It's easy: Run the next YAPC::EU! Frankfurt.pm did that and will start suffering tomorrow: Participants from all over the work will come to the German capital of the Internet and money to talk about Perl and meet other Perl guys.
How to convert a hash to a string? Perl is TIMTOWTDY but which way is the fastest? I need a checksum (hash, digest) for the hash, so the string must be the same for the same hash every time. Hash keys are not sorted, even a simple join('', keys(%hash)) may be different for each call (if the hash has at least two keys).
Ich bin svn-User und alle meine Begegnungen mit github endeten in Frust, denn die Useability ist mies, auch wenn sich in den letzten Jahren einiges getan hat. Git ist das gleiche wie github, oder? Dennoch, ich möchte ein OpenSource-Projekt unterstützen und dieses nutzt nunmal github, also bleibt mir keine andere Wahl.
Eigentlich wollten wir heute einen kleinen Rundflug machen und heute früh sah es auch noch vielversprechend aus - und dann kam das Wetter.
Perl subroutines may be called with or without leading & and with or without () at the end. Either one is strongly recommended - the command might end up as something else than a function call if both are missing.
SELECT-INSERT-UPDATE - Kombinationen sind unzuverlässig, die Gefahr eines doppelten Datensatzes der eigentlich einmalig sein sollte, ist zu groß. Die Alternativen funktionieren aber auch nicht immer, denn mySQL verhält sich inkonsistent.
Some people always complain, even about the language they've been working with for years while they has other options. One of them recently complained that Perl cleans up objects in unpredictable order during global destruction (after exit; and all END blocks). Here is what happend, how we tracked it down and solved it.
Data is getting bigger and bigger as technology advances. We didn't even think about using something inefficent like XML when I started writing sourcecode on a Datapoint 6600 or even in MS-DOS world, but today? A meg more or less doesn't matter today. But sometimes space is still premium and so it is for my current project. I'm working with short strings (text plus some extra chars, about 6 bit per char) and they should be compressed.
