In a recent #NT2tEU Twitter chat someone posed the question about how you link Twitter and Moodle together. There were suggestions about using your Twitter account to post messages about upcoming events and assignments in Moodle, linking back to them with the URL.
The way I tend to use Twitter and Moodle together is the other way round. I let Moodle take care of sending out the emails it needs for notifications, and I use Twitter as a way of pulling interesting feeds of information back into my Moodle courses.
To do this we are going to set up a Twitter Widget and then embed this code into a HTML block on our Moodle course page

If you want to do it here is the code:

We are just about to begin teaching our Python and Minecraft unit at school so I began testing everything out on our latest Raspberry Pi image to make sure we were ready for the lessons and adjust any of the lesson plans if necessary.
Our latest Raspberry Pi image runs Jessie. Now one of the improvements Jessie brings us is that the Print Screen button on your keyboard has been set up to run Scrot in the background to save a png screen shot into your home directory. You can read more about it here.
Now that is great as for quite some time taking a screen shot on your Raspberry Pi involved installing Scrot and then running it from the terminal; not the most user-friendly way to get students to take screen shots!

I have seen many posts on both Twitter and CAS about teachers having issues getting their class Raspberry Pis to update and install software through their school firewalls, so I thought I would share the simple solution that I have implemented at my school.
It actually leverages something that I put in place for our Ubuntu Linux servers, but works just as well for Raspberry Pi devices too.

We have just purchased a set of Raspberry Pi 2 boards to upgrade our Raspberry Pi B+ / HDMIPI set-up which we have been using for Computer Science this year. I will not go into the reasons why or the specifications of the Raspberry Pi 2; but needless to say the performance increase seen will make teaching with these devices much easier!
So we received our new Pi 2 boards and got straight into removing the old B+ boards from our HDMIPI set-up and installing the new Pi 2 boards. Pretty soon I ran into an issue though; having replaced the Pi board and using one of our SD Cards with our current image installed on it, the system would not boot; it just sat there at the rainbow boot screen. It turns out that the Pi 2 has an updated ARM processor and therefore needs the latest updates installing for the Pi to boot. Now I could have just downloaded the latest Rasbian image and been up and running, but we have quite a few customisations to our image which I wanted to keep
