Perl
Ich nutze MongoDB schon seit über einem Jahr, bisher aber nur für kleinere Sachen - und ohne MapReduce. Dabei ist es genau diese Funktion, die viel zur Macht dieser ungewöhnlichen Datenbank beiträgt.
Someone asked me about a CRC32B checksum today. No problem, there is CPAN and a common checksum like CRC should be very easy, there must be a module (or two or three or so) on CPAN, task done, next one. Stop. There are two modules for CRC32: Digest::CRC32 and String::CRC32 but really nothing for CRC32B.
I need to encode and decode a complete hash tree (a value which might be a reference which might contain other references which might contain other references which...) and there is no "Encode::Tree" or "Hash::Encode" module on CPAN.
Last day of YAPC::EU 2012 (for Max, it's Friday today) and time for the last YAPC day report.
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.
