Initially ubuntu seems to have RubyGems 1.01 and 1.2.0 installed : > gem --version 1.2.0 >/usr/bin/gem1.8 --version 1.2.0 >/usr/bin/gem1.9 --version 1.0.1 ...

I haven’t used ruby for a while, but recently wanted to try out {{ “github.com/aanand/git-up” | ext_link: “git-up”}} on OSX. According to the {{ “github.com/aanand/git-up/blob/master/README.md” | ext_link: “instructions”}}, a simple gem install git-up should work : > sudo gem install git-up Updating metadata for 1 gems from http://gems.rubyforge.org . complete ERROR: could not find git-up locally or in a repository I assume this is something to do with gem hosting moving to github or something… I haven’t really been following ruby for a year or so so I’m not sure exactly what’s going on.

If you’re getting missing separator errors in your makefile, similar to the following : Makefile:22: *** missing separator. Stop. … make sure you are using real tabs instead of spaces. A global search and replace for four-spaces should fix things up.

I’ve over-ridden several of the built-in django auth and {{ “bitbucket.org/ubernostrum/django-registration/” | ext_link: “django-registration”}} templates so I can have my own custom-styled login and registration pages.

Obviously we’re going to need scala before we can do anything useful; the easiest way to install it is via macports . We’re also going to need maven. > sudo port install scala > sudo port install maven2 Scala seems to have moved their repository to github, and the old google code repository no longer works.

I have a users table and an assets (basically just images) table, and I want to select and display a random asset for each user. I want to show a list of users, with a random thumbnail for each user from their assets. I could do this easily enough in code with multiple queries, but it seemed like a nice challenge to try and find a pure-sql alternative. ...

Unfortunately the only way to change the server header in nginx is to actually recompile it from source. Luckily this is quite easy.
