I can't find these instructions anywhere online - so I hope these notes help! The AS302P SMETS2 has two buttons. I've labelled the top button A and the bottom button B. Press the A button once to bring up the menu. The display should light up. It should show "General". Press the B button. This scrolls down the display. Press it a couple of times until it says "Registers". If you go past it, press it again and again until Registers scrolls back into view. Press the A button to enter the…

My colleague was understandably ticked off with me. A week previously, they'd asked me to get something fairly urgent done. I hadn't done it - and all hell was breaking loose. I wasn't being truculent or disobedient. I simply hadn't seen their message. And it was all Google's fault. At work, we use Google's G-Suite. It's a brilliant set of email and document tools. It also contains two incompatible messaging apps. When I started using it - the chat product was "Hangouts". At some point,…

I was signing up to a website the other day, and it wanted to know my title. Here are the options it offered me: Look, I get it. If I'm ever daft enough to undertake a PhD and masochistic enough to complete it - I am going to demand that everyone addresses me as Doctor Who Doom Octopus. But why this ordering? Why distinguish between male and female doctors? Let's see if the source code holds any answers. As many of you may have guessed, the website is German. Herr Doctor and Frau Doctor…

The good folk at Nooie have sent me their 360 WiFi camera to review. Cost is usually £50 - but check the bottom of this post for a discount code. The design is gorgeous - and award winning. It's a sleek unit and, surprisingly, feels nice in the hand. It can store videos on an SD card (not included) or via the cloud. The app - which is pretty nice - also lets you view the camera when you're away from home. Let's tear straight into it! Unboxing Standard image Night Mode In low light, …

I've never "got" the appeal of a Mac. But I have to use one for work. Here's a partial list of everything I cannot do on a Mac, but I can do on Ubuntu. These are all objective facts. These are things which either are impossible, or require adding unsupported 3rd party software - sometimes at a cost. Resize the system font I find the menu bar at the top too small. The only way to do this on MacOS is to lower the resolution of the entire screen! < p> Change the system font I know…

HTML is magic. It comes with all sorts of great usability and accessibility features. But people often ignore them or misuse them. Take a look at these checkboxen: If you click on this label, nothing happens. If you click on this label, the checkbox will toggle This is important. Tapping on tiny squares is hard for lots of people. Whether they have visual impairments, motor issues, or just a dirty touchscreen. You should give your user the biggest possible target area to interact with an…

I'm trying to create some ridiculously tiny audio files. The sort where every single byte matters. I've encoded a small sample. But the opusenc tool automatically adds metadata - even if you don't specify any. Using the amazing Mutagen Python library I was able to completely strip out all the metadata! import mutagen mutagen.File("example.opus").delete() It edits the file immediately - so be careful! But what is it actually doing? I wanted to understand a bit more - so let's go…

Apple's attitude to usability is... complex. The general attitude of "you're holding it wrong" seems to be prevalent across all their products. I like having a large mouse cursor. I find it easier to see on my large monitor, especially when sat at a safe distance. But, if I use a large cursor - I can't see the tool-tips underneath it. Annoyingly, Apple don't include the larger cursor sizes when taking a screenshot. So you get the joy of me pointing a camera at my screen like some kind of…

I need a new laptop. My old one is dying a long, slow death. My requirements are modest - runs Ubuntu and charges via USB-C. Cheap would be a bonus - as would a num-pad - but I'll take what I can get! Loads of people have recommended the Dell XPS13 series. I'm looking at them and I'm a bit confused (so what else is new). I'd appreciate your advice gentle reader. There are two models available. Here are the main differences between them: New Old CPU i5-1035G1 Processor(6MB…

Mums, eh? One minute they're teaching you how to read and write, the next minute you're teaching them how to video call casting directors during quarantine. You see, my mum is an actress. When people ask "what sort" - I could tell them about the award winning short films she has been in. Or the London theatre productions she's starred in. Or the TV commercials you've almost certainly seen. Instead, I show people the photo I have stored as her phone contact. Somehow, my mum has found a niche …

We have just installed solar panels on our house in London. We also had panels on our old house in Oxford. How do they compare? Oxford London Latitude 51.753738 51.486880 Panel Size 4000 Watts 5040 Watts Orientation South East/West Split Obviously, it's hard to compare exact weather conditions - lower temperature makes for more efficient generation - but I've picked a date in April where both sets of panels seemed to have an unblemished view of the sky. …

WebP is the hip new image format on the scene. It offers unrivalled image compression at superior visual quality. But, in my opinion, it is deficient compared to JPG in one significant aspect. It doesn't have a progressive mode. Progressive mode is useful because it can quickly load a low resolution preview of an image, and then gradually improve its quality. WebP, by contrast, just loads up the full image line by line. That's can be annoying on a slow connection. What if we could change…
