Seth from Berm Peak talks about how he used some LLM tools to make a local controller for a (terrible) e-bike gated behind an abandoned app.

Donations hasn’t been a successful path for the wider internet, no reason to expect any difference here. Ads embedded in the images, or perhaps listen to a message from our sponsor while we prepare your PDF?

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.

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.

Maintainance and upgrades. These big shared facilities they are shutdown regularly and researchers work flat out while they're up.

Hah, also fair point - there are plenty of people who would say this completely earnestly! :)

I read this with a large /s on the end...

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.

Why not? It's a factual report stating that the AAIB has opened an investigation into a potentially dangerous incident. There's not any editorial bias evident. See other extensive comments as to why this is not just a case of "it landed, so what's the problem?".

Based on the title, I was hoping this would be a new subclass of tower defence. Vibe coded, naturlich.

I chuckled seeing it in the first presentation of the conference. By the end of the conference, it was numbingly banal.

The Raspberry Pi SoCs optimised for cost rather than power consumption (or maximum performance). This is an engineering trade off, not a criticism. More power partitioning requires more area, more complexity in design and verification, and more expensive external components to support the internal voltage domains.

Another comment mentions the RP2xxx microcontrollers. If you look at those, they are optimised for compute power and data throughput rather than low power operation. I think it's a reasonable choice - the Pico boards are pretty sturdy and the original target is people running MicroPython, Arduino, etc rather than looking for µA standby currents.

It seems that the very long videos are a reaction against the very short clips. Usually the topics and density of information are not enough to consistently fill that amount of time, whereas it would be perfect in 10-30 mins. 60 secs: too short to convey much, 60 mins too long to convey too little.

This is a pretty standard document length. Modern microcontrollers have similar lengths (e.g. ATSAMD51 is ~2000 pages). Some of it is not software related, things like pin outs and electrical and mechanical descriptions.

It does take a huge amount of work to write and maintain. Typically the authors are not technical, so it also relies on the designers being available to answer questions as well. Then there’s a choice of how it’s written: narrative and potentially imprecise but readable, or terse and precise but hard to read. There’s both styles in the same document, terse for register descriptions.

The two big differences are 1) the rate of change (a huge amount higher than most planetary systems) and 2) that we have a large and growing population dependent on the many services our planet provides at a stable temperature. Of course, completely neglecting the rest of the natural world.

Much of the actual day to day work is. Typically graduate students, so they’ll be 22-26. That’s not a critique of their intelligence or potential. Students get progressively more experienced of course, but professors aren’t writing code most of the time.

A problem with academia in general is the lack of staff positions. Post docs finish their time then it’s either leave academia or become a professor. There’s few positions for those who want to just do research as a career, rather than pushing for a professorship. This means there isn’t a stable and experienced core of people.
