CentOS & RHEL 6.3 missing libnetfilter_queue

I am no Linux expert so it bugs me when I have to go hunting for packages to meet my requirements. In this case I was trying to setup a new CentOS 6.3 development VM for my project OpenNOP. To build OpenNOP it requires libnetfilter_queue & libnetfilter_queue-devel. These are very popular packages now and most distro have them out the door. Debian, Fedora, openSuSE are the ones I know of to include these packages. Now that would be fine if these were burried away down in some "extra" or "contrib" repo but no they just dont seem to exist. Redhat has not packaged them for RHEL thus CentOS does not have them either.

Well to finally end my frustration I was able to find a repo that contains these packages for me and from a trusted source. ClearOS the gateway appliance based on CentOS has built packages for libnetfilter_queue and libnetfilter_queue-devel.

Just create a new repo and enable them to install the packages. Then disable them when finished. They offer almost all the same packages as the RHEL/CentOS repos so we want to be very careful when using these. Be even more careful when trying to update them.

Grading the quality of your source code

While reviewing the source code for OBS over on GitHub. I stumbled upon a very neat little tool called Code Climate. It reviews your code and provides you with real-time feedback on it's quality. Currently Code Climate only supports Ruby and while that helps me very little the concept is still pretty great. I asked them if they had plans to include other languages for their service. They answered "Yes" but did not have any plans to include C or a link to SVN at this time. If you’re into Ruby and Git it’s a pretty neat tool. I hope they will soon include other languages and help people make better code.
