Picking up from Episode 2: Good Idea Fairy Hunting we continue exploring the concept of security as a people problem. This week we stop to take a moment to focus on the Who rather than the What is attacking us. In CyberSecurity, we tend to get caught up in things that happen to us, that we forget that it is actually a person attacking us. Learning more about who wants the information we have will tell us the ways they g...

HPR3601: Re: The Worst Car I Ever Had
May 23, 2022 00:00 - 3.34 MBIntroduction This episode was prompted by show 3542 from Beeza entitled The Worst Car I Ever Had. Here’s my story. I moved to Edinburgh in 1981, and before long bought myself a car - the first one I had owned. Before that I’d owned a series of Lambretta motor scooters and small to medium powered motorbikes. I’d been using a bicycle a lot after that. The car I bought was an oldish Peugeot 104, small, not very powerful, but it did the job. It was fine for driving around town and I used it ...
HPR3600: Digitizing Photos
May 20, 2022 00:00 - 7.11 MBToday most photos are in digital formats, such as those you take with a smartphone, so they can be worked on with GIMP right away.

This is effectively a continuation of the last show, since we found we had lots more to talk about!

HPR3590: Directory Commands
May 06, 2022 00:00 - 7.72 MBAs we saw in the last lesson, DOS uses directories to organize the files on your disks.

This tutorial takes us through the various commands you can use to do this. Links: https://www.ahuka.com/dos-lessons-for-self-study-purposes/dos-lesson-10-directory-commands/

Even Linux and other FLOSS OS geeks not interested in what happens when you flick the power switch on a computer may find this episode (vaguely) interesting as some light is also shed on the philosophy of the different system architectures and their history (Ever wanted to know what an /360 IPL really is?

HPR3580: RAW images
April 22, 2022 00:00 - 8.24 MBMost of the time we work with JPEG images because that is the most common format for digital images. They have the virtue of decent quality combined with smaller file size, and so won't fill up your storage quite as fast. But if you want the highest quality you have to work with unprocessed images, called RAW images. These are simply the actual data recorded by the camera sensors, and they give you some advantages, such as better correction of white balance. But GIMP does not open RAW images...

HPR3564: Removing EXIF data from an image
March 31, 2022 00:00 - 6.3 MBIntroduction I’m writing a script to process image files sent in by HPR hosts with their shows. One of the things the script does is to strip Exif metadata from such images. That’s because this metadata may contain details that could identify the creator of the image - their camera, their location, and other things. Many people will be alert to this, but in case anything slips through it seems a courtesy to anonymise images sent to HPR. As I was implementing this I realised that one piece ...
