Having had the misfortune of navigating a particularly ineffective large corporate purchasing machine, this resonates. Nobody in the chain is interested in outcomes, they’re interested in completed process. The value of something to the bus

I recently got 20 reasonably complex 4 layer gold plated pcbs assembled for about $10 a piece by JLCPCB. Maybe 20 items on the BOM, 50 parts total. It’s insanely cheap. 5 years ago when I was last regularly getting PCBs built it would cost

Buildings can be built to higher levels of wildfire resistance. The fire spreads because burning embers are blown downwind, settling and starting new spot fires. If they get blown into a house, the house burns. You don't need to make a

I needed to normalise a big list of dates recently. I thought maybe GPT could help. It spat out a list of normalised dates which, after a bit of careful reading, were about 95% right. How can you trust a tool that's right 95% of the ti

I think that summer/winter distinction is really important. In the UK where most houses don't have air conditioning, you really don't want heat recovery for 1/3 of the year. On really hot days you might want to use heat

My experience of boiling water taps in offices is that they're not actually hot enough for decent tea. How's your experience been? Do you preheat your mug before brewing? I like tea strong and dark!

Demographics is destiny. If equity increases the living standards of todays generation but means nobody has kids, then it is not an idea which will survive to future generations. Unless western liberal society finds a way to either increase

I think it's pretty clear to everyone that teaching basic literacy - reading, writing, practical maths etc - is a huge societal benefit. Nobody is advocating for not doing that. What is maybe less clear is the benefit of extending form

There's a YouTube explainer somewhere. But the basic gist is that after developing the first Maslow device as open hardware, MakerMade sold their own version (with agreement from the original designer, who I don't think wanted to

I don't think it's simply "engineers hate open source". Most of the open source tools in the embedded space are just a bit crap. The reality is that good software needs many thousands of hours of development time. The em

I don't think it's strictly true that nobody has the problem of wanting to travel medium distances quickly. In fact, everyone has that problem - that's why the roads are congested and the trains are busy. It might be more acc

If I order from my local pizza restaurant for collection it ends up being about 50% of the cost of any food delivery app. I quite enjoy the walk too.

Thanks for applying scepticism to the claim! Yes, cruise ships are bad for all sorts of reasons - but from an absolute energy consumption point of view there’s no way they’re as bad as people are making out. Just as high density apartment l

Camper vans are already a big problem for some rural areas. And they don’t tend to contribute much to the local economy. You phrased it like that was a gotcha, but it’s not really. Camper-vans and cruises are both high-impact low benefit fo

I can only speak for myself - but the convenience and relatively low cost of Netflix killed piracy for me. It wasn’t really a moral reason, or a fear of prosecution. But Netflix is truly easy, and the cost isn’t significant. Spotify did the

Are you actually familiar with those projects, or are you just posting links? Nano Framework is a framework to run C# apps on microcontrollers - but when you get to the hardware interfacing, it's done in C++. Look at https:/&#x2F

SIM cards are a weird exception because they have a hardware computer designed to run a subset of Java. Normally Java compiles to a bytecode which is run by the Java VM - in SIM cards the VM is a hardware implementation of the Java VM. That

Rust compiles to native machine code. C# compiles to bytecode which runs in a runtime environment. That adds a huge amount of overhead, and means you don't have direct access to the hardware registers. The .net IoT framework is targeti

I sometimes get nosebleeds. There's no pain involved - it just feels like a slightly runny nose until either you wipe it or blood starts dripping into your frame of view. I get them a lot in low humidity. I haven't watched the vid

As an embedded engineer sometimes working on PWM, it's interesting to think that the origin of the gate drive signals is still just some sort of microcontroller timer running at 3.3V and a few mA. I'm sure there's a few layer

How can you even judge how basic it is just from the photos? A $10k bike designed for racing has the same kind of components as a $100 bike from Walmart, but every single one of them is far, far better - better materials, higher tolerances,

I was briefly a member of a makerspace with a laser cutter - and it was brilliant! The ratio of effort to results was far better than any other CNC tools I’ve used. But then COVID and moving house put an end to that. I’d love to recreate so

My comment had nothing to do with Javascript. Rust may not have "left pad" type micro-dependencies, but it definitely has a dependency culture. Looking at `cargo tree` for the medium size project I'm working on, the deepest d

The education point is interesting. If you grow up as a hunter gatherer, there are powerful forces you don’t understand trying to take resources away from you. If you grow up in a capitalist society, there are powerful forces you don’t unde

There's probably a similar amount of code in the execution path, but the Rust ecosystem reliance on dependencies means that you're pulling in vast amounts of code that doesn't make it to your final application. A C++ library
