Storage terms iBook (#Nat5, #iGCSE, #CompSci) #cc0

  

I had a few hours to fill on my flight this morning so decided to finish off a few iBooks which I’d been experimenting with this session. The one on storage terms is short and sweet, with video examples of conversion between bits, bytes, kilobytes, megabytes, gigabytes, terabytes and petabytes. There are also a few challenges (and answers) too.

Not on the iBooks store but you can download here

Feedback gratefully appreciated.

CC0 means use it as you like!

#GAFE Google Mail Tip – Filtering out calendar RSVPs

Email invites and responses can very quickly clog up your inbox. The following guide explains how to redirect or archive some of these. Be careful (if adapting this filter) not to accidentally filter out the invitations from others!

In Google Mail type the following in the search bar:

(subject:”declined:” OR subject:(“accepted:”) OR subject:(“maybe:”)) has:attachment invite.ics

Then click on the drop-down arrow to the right of the search box and select “Create filter with this search”

Tick or make a selection in the appropriate boxes and then click on “Create filter”.

All future email invitation responses will be filtered according to your settings.

Rebuilding the PiLab

Rebuilding the PiLab

We moved into the new Science and Technology Building at our school just a few weeks ago. Since then, classes have been taught, exams have come and gone and boxes have been unpacked in between.

Over the past few days some students from my Makers and Breakers lunchtime club and I began to set up the Raspberry Pi devices in their new classroom. As we were lucky enough to have HDMI monitors in the new rooms, with on-screen controls to switch between inputs, I wanted the Pis to become permanent fixtures rather than devices hidden away in a cupboard outside of club time. We decided on two per semi circle (of three or four machines) which would always allow for at least one Windows machine for Internet access in case of troubleshooting.

I used small Velcro coins to attach the Raspberry Pi to the top of the PC base units and then added the HDMI cable to the very tidy bundle feeding into the monitors. Numbering each case with a Sharpie to match its SD card means that students can continue their Pi experiments from lesson to lesson.

Each Pi has been given its own cat 5 cable and I intend to use a collection of recycled BT Homehubs to set up mini wired networks as and when required. The holy grail is to be granted access to the guest wifi but Python and minecraft tasks will work just as well for the moment.

The new setup removes the need for students to spend most of their club time assembling and disassembling the devices – now we can (almost) get straight to the fun!
