Thoughts on building an NFC reader for the Framework laptop

Small circuit board.

The Framework laptop has several little slots which can be used be used to expand the functionality of the laptop. They convert the internal USB-C ports into a different sort of port. For example, Framework sells an official HDMI card and Ethernet card: But the community have built their own SD card expansion pack as well as 3D printed snack drawers: Brilliant! I have an NFC-only…

Screenshot of a user interface showing a 2D view and a 3D view of my scan.

Several years ago, I had a CT scan of my jaw. The dentist wasn't sure if she was allowed to give me a copy of the scan, which led me to ask "who owns the copyright to my medical images?" I still don't have an answer to the copyright question - but I do now have a copy of a CT scan! Last week - following some dental trauma - I had another scan of my head. The dentist took great delight in…

Book Review: The Terraformers - Annalee Newitz

· 1 comment · 200 words


Book cover showing a towering structure covered in plants.

This is a fascinating story told on an almost geological timescale. It is a tantalisingly glimpse, into a much larger world. It is a story of contradiction - there's an epic universe, but we're stuck in a parochial backwater. It is full of un-human creations - yet its politics are firmly a reflection of the 2020s. I loved the story - it's almost impossible to describe how wild it gets - but…

Fifteen MegaWatt Hours from Sunshine - Four Years with Solar Panels in London

· 1 comment · 550 words


Chart 4: Mean domestic electricity consumption (kWh per meter) by country/region. Varies between 2,973 and 3,870kWh.

Just as the UK was entering the first COVID19 lockdown, we got solar panels installed on our roof. Four years later and our generation meter shows they have produced 15,480kWh of electricity. That's a rather impressive 3,870kWh per year. This is what the average UK household uses in electricity: Our roof is non-optimal. We have an East/West split rather than the more usual South-facing…

Receive push notifications from your rice cooker

Android alert telling me that the rice is ready.

I have a lovely, and reasonably priced, Mini Panda Rice Cooker. It does not have any SmartHome features. You put in water and rice, press a button, it cooks rice. Nice! The only problem is - I don't know how long the rice will take to cook. It uses "Fuzzy Logic" to work out exactly how much heat and time is needed for perfect fluffy rice. This is inconvenient. I cannot always hear the beep the…

Restaurant Review: No Catch - Vegan Fish and Chips

· 200 words


Artful photo of a large piece of battered food shaped into a curved fishtail atop a pile of chunky chips.

There's nothing finer to do in Brighton than walk along the promenade eating a wodge of chips the size of your face. But it was raining, so we sat inside and ate all the chips instead. This is Brighton's 100% vegan chippie. As well as big fluffy chips, battered (veggie) sausage, and all the standard condiments - they specialise in fishless-fish. It looks like this: Thick and juicy plant-based …

There's nothing you can do to prevent a SIM-swap attack

It is tempting to think that users are to blame for their own misfortune. If only they'd had a stronger password! If only they didn't re-use credentials! If only they had perfect OpSec! If only...! Yes, users should probably take better care of their digital credentials and bury them in a digital vault. But there are some things which are simply impossible for a user to protect against. Take,…

A personal WordPress MonoRepo for my themes and plugins

· 350 words


The Logo for WordPress.

I use a self-built WordPress theme for this blog. I also use a variety of self-developed WordPress plugins for various enhancements. I used to publish these plugins, but I get terribly confused by the SVN shenanigans involved, and they weren't used by many people, so I stopped. Recently, I've been moving all my plugin code into my theme. This is sort-of-but-not-quite a MonoRepo. I've also…

Solved! "Access Point Name settings are not available for this user"

Access Point Name settings are not available for this user.

Android's user-hostile interface never fails to disappoint! I was struggling to get a new eSIM working. I could make and receive calls / texts, but data just wasn't connecting. I tried rebooting, flipping to aeroplane mode, changing bearer, manually selecting the network. Nothing! Then, I remembered my ancient GSM knowledge. All mobile networks need an APN - Access Point Name - in order to…

In the IndieWeb movement there's a concept of "POSSE" - Publish Once, Simultaneously Syndicate Elsewhere. You should publish your words, pictures, songs, reviews on your own site. And then you can choose to share them out to where your audience is. Perhaps that's posting the link on Facebook, or a copy of a photo on Instagram, or sharing the episode on YouTube. There's no shame in meeting your…

What the UK Government gets wrong about QR codes

A leaflet for Childcare with a prominent QR code.

One of my most memorable experiences in the Civil Service was discussing link shortening services with a very friendly person from the Foreign and Commonwealth Office. I was trying to explain why link shortners like bit.ly and ow.ly weren't sensible for Government use. They didn't seem to particularly care about the privacy implications or the risk of phishing. I needed to take a different…

X-ray of teeth on a computer monitor.

You know that ice-breaker game "Two Truths And A Lie"? When I'm forced into some mandatory office fun, I always say... I've sat in the seat of a space shuttle. I still have two of my baby teeth. I used to be a voice-over artist. Well, one of those truths is about to come crashing down. When I was younger, I had two of my adult teeth removed. They were coming out at such a crazy angle that…
