As previously discussed, I'm doing the Certified Blockchain Professional course. It is self-directed learning, so I'm going through it at my own pace. In order to consolidate my learning, and help organise my thoughts, I'm blogging about my reflections on each module. These are mostly notes to myself - but I hope if you find something interesting (or incorrect) that you'll leave a comment. Can…

How I miss the days when phone manufacturers were innovative. Nowadays everything is just a boring black rectangle.

Probably sensible, but utterly BORING! Let's imagine …

I'm doing an apprenticeship MSc in Digital Technology. In the spirit of openness, I'm blogging my research and my assignments. This is my paper from the PP1 module - where I take some CPD related to my profession. I picked Machine Learning in Python. I've blogged about the course itself. The middle two parts of this paper are about that - why I chose it and how I put it into practice. The…

Quite often on the web, you'll see a set of "things" with a separator between them. For example, at the top of this post, you'll see Thing 1 | Something Else | Another Thing. This provides clear visual separation between logical groups. But there are a couple of problems. Firstly, the separator character may not be interpreted correctly by screen readers. They may read out "Vertical Pipe",…

During the middle of the 20th Century, the UK's Royal Air Force took thousands of photographs of the country from above. Think of it like a primitive Google Earth. Those photographs are "Crown Copyright". For photographs created before 1st June 1957, the copyright expires after 50 years. Recently, the organisation "Historic England" started sharing high-resolution copies of these photos on a…

Not really a security issue, but one which I thought was worth highlighting. It shows the peril of slightly vague specifications. When you scan a 2FA token into your authenticator app via QR code, you get presented with a bunch of information about your account. This lets you store things like the issuer and the account name. I recently scanned a code, and it displayed my name as Terence+Eden. …

Yes yes, Cunningham's law etc etc! I want to play around with 2FA codes. So, I started looking for the specification. Turns out, there isn't one. Not really. IANA has a provisional registration - but no spec. It links to an archived Google Wiki which, as we'll come on to, isn't sufficient. There's some documentation from Yubico which is mostly a copy of the Google wiki with some incompatible…
