Have you ever tested various PWM frequencies? 50/60Hz is very noticable - but if the PWM is switching at 1000Hz? 5kHz? There is presumably a rate at which it is imperceptible to you? Apparently Philips Hue uses 500-1000Hz. I wonder if

Larger animals tend to more intelligent - presumably there’s a natural limit to the size of prey a carnivorous plant can reliably catch from a static location.

Unfortunately the moment the environment and energy are involved, journalism falls apart. "Water consumption" is a meaningless metric if it 's not accompanied by other information - location, energy intensity of water, source

I briefly got excited about the possibility of local LLMs as an offline knowledge base. Then I tried asking Gemma for a list of the tallest buildings in the world and it just made up a bunch. It even provided detailed information about the

LSD and amphetamines basically don’t have the same effect at all. I wonder which one it is.

Judging by their website, it does take off vertically, but just didn’t in this flight. Which makes sense if this was the first flight away from the airport. They need to do things in small steps and validate each one.

I imagine standards have also shifted. It just wouldn’t have been possible to wash a child’s clothes after one wear before the invention of the washing machine. People also had far less clothing that they could have even needed to wash.

Biological muscles are proof that you can make incredibly small and forceful actuators. But the state of robotics is nowhere near them, because the fundamental construction of every robotic actuator is completely different. We’ve been build

In my experience (as a man) men tend to behave quite differently when there’s no women present too. Generally I much prefer mixed gender socialising!

A longer cable won't just catch fire, because the power dissipation per unit of length is the same regardless of overall length. Imagine the most extreme case - a cable so long the voltage difference is 0V at the end. It's basical

I've had plenty of colleagues who expect the job to be that. Just working on a small ticket and moving it to "to test" when done. It's incredibly frustrating to try and get anything done in a team like that. The reality

I worked in RF (radar) for a while and the dB/dBm is an incredibly useful tool there. It makes reasoning about amplifier chains and insertion loss so much more straightforward. It also means you can talk about transmitters and receiver

Yeah this. In the UK we have a real problem with completely unearned authority given to people who went to prestigious private schools. I've seen it a few times. Otherwise shrewd colleagues interpreting the combination of accent and ma

The limiting factor in most structural uses of wood is stiffness not strength. You could build your floor joists out of scaffolding boards, but they'd bend unacceptably. Stiffness is basically a product of geometry rather than strength

Yeah - you can’t talk about renewable energy generation without also considering when it is generated. Then future price of energy will be incredibly time dependent. Finding a way to generate at a different time than everyone else - whether

We're talking about a carbon tax. By definition it is not on car fuel, but on carbon. You don't need state surveillance or tracking purchases. You just need to get to the source of the problem. Hydrocarbons leaving the ground. At

Rich people use more energy. That’s been shown by loads of studies. Maybe they drive a more efficient car, but they own much larger houses which are heated or cooled consistently, they travel a lot more, and they buy things with embodied ca

Outside of coding, Google's NotebookLM is quite useful for analysing complex documentation - things like standards and complicated API specs. But yes, an AI chatbot that can't actually take any actions is effectively just regurgit

The hidden factor here is that condensing boilers and heat pumps have non-linear efficiency vs flow temperature curves. Heat pumps in particular show high increase in coefficient of performance (CoP) as flow temperature drops. The other var

I think social media is reducing local accents in a way mass travel or media never seemed to - probably because it exposes people to “cool” accents in a way that old media never did.

You just need to listen to the various generations of the royal family to see that RP is effectively dead. I read somewhere that accents “move” up the social hierarchy over time. Aspects of speech which are widely working class will eventua

Everyone in the uk has a central hot water heater, and nobody has a hot-water plumbed dishwasher. Presumably the 230V supply is enough to heat the water up quickly. Do you also have hot water plumbed washing machines?

So you’re always pumping hot water through your pipes? Does that not end up wasting quite a bit of energy? I guess in winter it’s not a big problem since you’re heating your house anyway, but presumably in summer it is just adding unwanted

The Drogue IoT project is probably the best set of projects which enable building IoT devices in Rust. https://github.com/drogue-iot It’s built on top of the Embassy embedded async runtime (which is great), and implements a

I work in the embedded space. I'd absolutely love to have a tool to build immutable, signed distro images which I can push to devices with a/b style updates. I imagine you can do this with mkosi, but it doesn't quite feel lik

Can you share more about this? I think that's often the thing that kills my side projects. I'll make reasonable progress, lose interest for a bit, and then when I come back to it all the working memory is gone and so I spend a few
