What isn't realtime?


A digital watch.

There are a few heartstopping moments when you have to transfer a Very Large Amount of Money. Will the bank deny the transaction? Will I have to remember my mother's cousin's dog's maiden name? Will the money arrive safely? I clicked the "Transfer Your Life Savings" button on the website. An hourglass appeared. I flipped […]

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 […]

Viewing my CT Scan in 3D using Linux


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 […]

Book Review: The Terraformers - Annalee Newitz


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 […]

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


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 […]

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 […]

Restaurant Review: No Catch - Vegan Fish and Chips


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 […]

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


Photo of a nano SIM card and its plastic housing.

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 […]

A personal WordPress MonoRepo for my themes and plugins


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 […]

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 […]
