I don't know if it's because I'm, even after a year of Ruby development, still too much Java-minded and just don't get the idea of Ruby's class ... http://techlog.fetmab.net/wanna-have-some-fun-try-these-class-variables-and-forking/ Today we realized that the project is evolved enough to take some time and think about how we can cache things efficiently. One of the actions we were in doubt of most seriously is the action that responds to an AJAX call and returns you the position of the trucks that ... http://techlog.fetmab.net/cache-in-a-seperate-folder/ Hello there, it's late in Bremen, so I will keep this thing as short as possible: I just wasted the complete day's work at Tansporter due to a bad preparation... dumb me!

But let me explain this: We are just two guys, coding all day long. ... http://techlog.fetmab.net/periodically-executed-tasks-in-your-rails-application-without-any-pain/ Hey folks, I'm back from vacations. It was great, even if there was some snow shortage. We nearly all managed to get over the icy, artificial snow... nearly. On our third day's last run my girlfriend felt unlucky and hurt her knee so bad she might needs an surgery. But she's ... http://techlog.fetmab.net/back-in-the-game/ Ok ok ... it's time for some excuses! We've really neglected this blog for quite a long time but I promise to be back in the game starting in the early days of 2008! Before we get back to blog business I'll enjoy a ski holiday in Jasna (Slovakia) with my ... http://techlog.fetmab.net/using-flock-update/ While it is always good to have attr_accessible or attr_protected set in a ActiveRecord model class to protect it from abuse when updating any object of that class from the params of a Rails controller. But what to do when you have that attr_accessible but you won't let a certain action ... http://techlog.fetmab.net/updating-certain-fields-of-an-activerecord-object-from-params/ Rails 2.0 will ship with a new ActionController class method called: rescue_from Exception, :with => :method_name ...which will rescue all exceptions in actions, thrown when the application runs in production mode with the given method.

Sadly until now I had no time to watch ... http://techlog.fetmab.net/ruby-hoedown-sessions-online/ Yesterday I stumbled upon the firefox plugin YSlow. It analyses a website for 13 criteria that Yahoo thinks are reasonable for a fast or a slow loading webpage.
