Running Things Regularly - cron

Running Things Regularly - cron

Last week I showed you how to run something each time your Raspberry Pi boots. This is not the only way; there is also 'cron'. But cron is actually a more powerful command - it allows you to run anything at a regular interval, be it every minute, hour, day, month or day of the week! 'cron' is short for 'chronograph', or 'clock'. It is a daemon that allows you to schedule commands to run at specific times. These events are listed in what is known as the 'crontab' file, which is short for 'cron table'. To see what is...

Renaming your Raspberry Pi - the 'hostname'

If, like me, you have more than one Raspberry Pi on your network, then it is a good idea to give each one a unique name.  If you use Raspbian, then that name is 'raspberrypi' by default.  It is really easy to change that name to (almost) whatever you like.  This name is known as the 'hostname'. First, log onto your Pi and open a terminal window.  Your Pi's name is in a file called 'hostname' in the /etc directory.  Edit that file as superuser with: sudo nano /etc/hostname This file contains only one line - the name of your Pi....

Uses for the Raspberry Pi Model A+

Uses for the Raspberry Pi Model A+

The Raspberry Pi Model A+ is the little brother to the Model B+, and younger brother to the original Model A.  It is also by far the cheapest Raspberry Pi ever produced, costing half that of the current Model 2B.  It is also a much misunderstood member of the family, in my opinion, and is actually one of my favourite models for a number of reasons. So, what sets it aside from the other Pi's?  Let us look at some of the major differences:  Model Model A Model B Model A+ Model B+ Model 2B CPU Broadcom BCM2835 ARMv6 (single core)...

Alternative Raspberry Pi Operating Systems

Alternative Raspberry Pi Operating Systems

The original Raspberry Pi has always had a few different operating systems (OSs) available, albeit most of them based on Linux.  With the release of the Raspberry Pi 2 a few more are starting to appear.  The reason behind this is that most Linux operating systems are written to run on the ARMv7 architecture (the CPU at the centre of the Raspberry Pi). The original Pi's CPU was based on ARMv6. It is therefore becoming much easier for operating systems to be ported to the Pi2. The OS of choice has always been Raspbian, and there are no plans for it to change....
