Gcal the ultra-powerful command line GNU calendar

Filed under
Software

Gcal can be used for a lot of calendar related questions. A zillion calendar options (did you wonder what the old armenic months are?), more than you probably know about. Of course, if you are not a calendar freak, this is not the main selling point. Gcal works (and is intended to) as a diary, and appointment planner. It can also be used to determine sunset or sunshine in your local coordinates, and if you are an amateur astronomer, it can give you the twilight times. The same holds for data for the Moon, it can give you the moon phase, for instance.

Hey, its already the 21st century! Command line? I can hear you mumbling How come I have to use a command-line calendar?'Of course, if you are into really pretty UIs... Skip this article. This is more for the Unix/Linux user who just pops open a terminal and shouts gcal -f $mycalendar when he wants to know what today is due.

It is well-known that GTK+ gained support for client-side decorations a while ago – after all, most GNOME applications were quick in adopting custom titlebars, which have become one of the most distinguished patterns of GNOME 3 applications. However it is less well-known that client-side decorations may also be used for windows with no custom decorations, namely when using GDK’s wayland backend. Read more

PostgreSQL, the NoSQL Database

One of the most interesting trends in the computer world during the past few years has been the rapid growth of NoSQL databases. The term may be accurate, in that NoSQL databases don't use SQL in order to store and retrieve data, but that's about where the commonalities end. NoSQL databases range from key-value stores to columnar databases to document databases to graph databases. Read more
