http://momolog.info Die Firma MoMolog aus Berlin stellt sich vor. Projekte, Ideen und Aktuelles. Sat, 10 May 2008 10:08:30 +0000 http://backend.userland.com/rss092 en In what they call a "backwards compatibility change" the prototype core developers have introduced some changes to the prototype Hash class. A little history: From version 1.5 the Hash class started behaving a bit differently because now the Enumerable methods where copied into the Hash prototype instead of into the instances, as ... http://momolog.info/2008/02/09/prototype-hash-was-killed/ After installing Leopard, the previous Apache configuration file in /etc/httpd/httpd.conf is no longer used. The Apache configuration sits in /etc/apache2/httpd.conf now. In order to enable PHP again, I uncommented the following line first: LoadModule php5_module libexec/apache2/libphp5.so Second, to get my virtual hosts running again, I used the adapted Leopard version of Patrick ... http://momolog.info/2007/11/25/php-and-mysql-on-macosx-105-leopard/ Which Programming Language are You? http://momolog.info/2007/05/09/what-i-am/ A lot of nice things can be done with postgresql's hstore type. They are a nice way to store flags, for example, and by providing an aggregate function to sum them up, one can easily compute complex unions of properties. First we define an aggregate function to sum postgresql hstores, straightforward as ... http://momolog.info/2007/04/17/hstore-magic/ Some days ago I tried installing svk on MacOSX using fink. Everything worked fine except when I finally tried to use it: aljoscha% svk Can't locate Class/Autouse.pm in @INC (@INC contains: /System/Library/Perl/5...

BEGIN ... http://momolog.info/2007/02/23/using-finks-svk-on-macosx-with-zsh/ These tests check that, with the prototype fix in place $H({fruit:"apple", vegetable:"cucumber"}).reject( function(el) { return (el[1] == 'cucumber');} ) == $H({fruit:"apple"}) and $H({fruit:"apple", vegetable:"cucumber"}).findAll( function(el) { return (el[1] == 'apple'); } ) == $H({fruit:"apple"}) // http://momolog.info/2006/10/16/testcase-i/ The following article describes ticket #3592 in the RoR Trac and explains a proposed solution. Prototypes Enumerable mixin class does not properly respect the mixees internal format. For example the reject and findAll methods, operating on Hashes, return Arrays instead of Hashes. var a = $H({a:1, b:2, c:1, d:3}); document.writeln(a.inspect().escapeHTML()); =># var b = ... http://momolog.info/2006/10/14/prototype-enumeration/
