• modern CMake is required for building a lot of new software
• CMake is dependency for many packages (e.g. ROS related)
• we don't want to remove CMake (which would remove packages that depend on it)
• we want safe procedure to update CMake that can be reversed easily

So yesterday brought the sad news that Google Reader is being killed off. C’est la vie it seems, given it was a Google product. In my search for an alternative I rediscovered Fever and decided to see if I could run it up for free on Heroku. Onwards...

Personally I think the news about Reeder is quite sad, as I would quite happily have paid for it as a service. In fact I like RSS so much that I actually shelled out the $30 for Fever when it first came out years ago (I was also pretty massive Shaun Inman fanboy if I’m being honest).

I ended up setting Fever aside because screw having to manage self-hosting for PHP and MySQL, right?

If you’re new to Fever I recommend going and checking it out, but also reading the post in response to the Google Reader announcement by Fevers author, Shaun, for a good list of what Fever is and isn’t.

Enough jibba-jabba!
