  • Themed days in support

    I notice that we seem to have waves of support in various ways. One day we will start our shift and be totally overloaded the entire day, so busy that we end up doing a little extra after hours (posting this blog whilst cooking dinner today!). Other days its pretty dull so we play table…

  • nginx hacking using proxy

    It sucks getting hacked Every now and then servers get hacked. Often because of an exploitable webapp, or because (most commonly) a weak, easily guessable password was used on a well known user account (like ‘root’ or ‘info’ or ‘test’).

Package Management If your Linux distro is RedHat based (ie Centos, , then you will be using yum and RPM.   RPM is for doing individual package manipulation (installing,…

  • Chrome OS and Linux

    I had high hopes for netbooks bringing about an increased mindshare for Linux for ordinary users.  This didn’t quite pan out unfortunately and it’s nigh impossible to find a Linux netbook at a brick and mortar store these days.  Users loved the low price and mobility of a netbook, but (seemingly) didn’t appreciate the lack…
