Redhat release software collection January this year. It’s kind of cool as it lets you install newer versions of ruby perl python etc. Gitlab requires version ruby193 which is very easy to install with scl. This install guide is based on the original gitlab install guide which can be found here “https://github.com/gitlabhq/gitlab-recipes” and shows you howto…

Got a nice hint from Oracle this week that they fixed the lack of having CVE information in their yum repos. As I wrote in a previous blog post, it was disappointing that at the time of releasing OEL for the “masses” they did not have metadata available which put them on par with CentOS….
Last week I was building up a RabbitMQ cluster with shovel from New York to Los Angeles. As we use a dual stack environment ipv4/v6, I expected that RabbitMQ would resolve the ipv6 address first as normal Linux systems do. So I begun to do my tests and realized, that it didn’t. My publisher (see…
Last week I came across this link: http://linux.oracle.com/switch/centos/ and thought “wow, this might be a very nice alternative to RHEL.” Here is a quote of Oracles site: “FAQ Wait, doesn’t Oracle Linux cost money?
