    I like gnome-shell, but some visual elements annoy me, particular anything that uses vertical real estate, such as titlebars, tab bars, etc.

    The desktop's top bar can be hidden using the hide top bar extension. This hides the bar at all times, except with in 'overview' mode (i.e. when the mouse goes in the upper-left hot corner or by pressing the 'super' key on the keyboard, which by default is the left Windows key between Ctrl and Alt).

    For window titlebars and terminal tabs, it can be fixed using CSS styling.

    A few clients received the following e-mail [...]. The screenshot included a listing of the root directory of the website, which had one non-standard directory specific to the client, so it was a rather good hint that he had access to privileged information. I am always skeptic of such emails, usually scams, borderline extortion, but in any case the screenshot did provide sufficient proof to investigate.

    Icinga 2 which was initially released around July 2014. Icinga is a fork of the Nagios monitoring system, meaning that it can do periodic checks to servers, services and networks to make sure everything is running smoothly. If not, it can e-mail, text or phone a system administrator.

    Staying close to Nagios syntax had its comforts, but it also meant keeping some of its limitations. Icinga 2 is more of a complete rewrite. The documentation keeps talking about node communication with SSL and a 12 step program to get started... with nodes. What if you just want to convert your Icinga 1 configuration and see how it goes?
