I was addressing your statement that Earth is always changing. Yes, of course it is, obviously at +/- 20°C little that we recognise now would survive, but the transition is a lot less painful for you and yours if it happens over millions of years rather than a few centuries.

The one hope is that renewables and batteries continue to reduce in cost, and grids everywhere develop around that paradigm. Economically, it’s inevitable, but there’s a lot of (to be stranded) money, social, and political will against it.

Your car can go at 0 kph and 100 kph. It’s the rate of the change that kills you, not the speed.

It’s also been tried (endlessly), but society is too enamoured with consumption and GDP as the principle guiding metric for it to have had much effect. Some large number of people, wilfully or otherwise, reject intellectualism as a whole.

Regulation aside, a significant issue is physical area. Most people won’t have access to enough area in the right direction to make it a primary source.

I'm don't think it's ridiculous - it's simply a positive acknowledgement you've seen the message, even if there's no action required. The alternative would be repeated reminders until some timeout. I would imagine that timeout might come with an enforcement order, even if you have nothing to declare.

This is not the case here as the software is required to use the hardware they’re selling at any quantity. The software is cost entirely for them, if you’re not buying the hardware you’re not using the software. Given they support Linux for the paid version, its development is already paid for. Absolutely say you won’t provide support for free tier users. Today’s free tier users are tomorrow’s purchasing managers. FPGA is not a big market, so you have to capture comparatively few people for each unit of market share. Good silicon without good software is just very expensive sand.

No, you don't have to. If you are employed through a company, stay below £100K income and don't have other income then (generally) you don't need to do a tax return - it's all handled automatically through pay as you earn payroll. However, as shown, a lot of people are self employed, want to claim deductions, have some side income etc. However, for those that do need to, it is really straightforward.

A lot of people in the UK file their taxes (~12 million, roughly 35% of employed adults, not taking into account those unemployed with assets and pensions), but the self assessment is straightforward and very easy to use.

Yes, the newer suppliers have EV and solar friendly domestic tariffs. Plug it in overnight, and the supplier determines when the charge happens and charges at the reduced rate.

N=2, but my Decathlon bikes have well over 50000 km between them with no issues, beyond the usual wear and tear. Value wise, they are fantastic. They are road bikes, however, not the folding specifically.

Link to Mark Owen’s excellent QFP library for soft float on Cortex-M0+ (ARMv6-M) and Cortex-M3/M4 (ARMv7-M).

Nice write up here, too, I like the idea of a firm float.

My feeling about programmable IOs is they’re fun, but not the right choice for commodity high speed interfaces like USB. You obviously can make them work, but they’re large compared to what you would need for a dedicated unit. The DVI over PIO is a good example: showed something interesting (and that’s great!) but not widely useful. Also, a lot of protocols, even slow ones, have failure and edge cases that would need to be covered. Not to mention the physical characteristics, like you’ve said for high speed USB.

One person in the Lords raising the issue in no way constitutes widespread calls for conscription.

I haven’t heard a peep about conscription, can you provide a source? There was some vague national service proposal for school leavers a couple of years ago, but that was it.

Maximum power output and maximum (assisted) speed are generally legislated. In the UK, an e-bike is up to 250 W and 25 kph. More than that, it would classify as a motorbike and you'd need a license (not particularly onerous). The bike itself is often built differently to accommodate the different power profile.

As a pedal cyclist, I feel that's a reasonably sensible limit as much faster than that you should be more experienced as a cyclist to control the bike and anticipate the conditions.
