use %q to create strings

In my gemspec created by jeweler I saw string creating using %Q. What? I found a page describing ruby string creation, and it seems %Q is the equivalent of double quote delimited strings and %q is the equivalent of single quotes. While i was pondering what the advantage could be of writing it that way, […]

easiest dual boot ubuntu install

I wanted to convert my XP laptop to a dual boot with Ubuntu or Kubuntu. Whichever. I want to try out linux and maybe switch altogether. Run windows inside a Virtualbox if i would really need it (e.g. for work). So i looked up different tutorials, while i was cleaning up disk-space and suddenly bumped […]

script/plugin install from git fails

Mongrel_service can cope with this much better: it also keeps a check on your ruby process and restarts it if needed (at least in the old version, i hope […]

accessing current_user in models

Up until now i was able to somehow circumvent the need to access the current-user in the model, by calling methods from the controllers and handing down the current-user. In the MVC pattern, the model should know as little as possible about things the controller handles. But now, i need a method that will check […]
