(hackeridiot12 may be Jewish - IME Jews often type "G-d" because spelling the deity's name in impermanent text is disrespectful. Bit odd from my perspective, but harmless :))

Foundation licensee here in the UK, working on my Intermediate (and hoping to pass that exam this year). I manage the radio system for the UK Discworld Convention (every other year…

Simplified English is a thing that exists, for clarity - see for example https://simple.wikipedia.org/wiki/Practice I don't know if the parent comment was trying to equate American…

XRF will go a millimetre or so into the sample AFAIK - it's mainly useful for finding alloy contamination, e.g. "this is 99.99% gold" vs "this is 73% gold and 27% other things" - y…

Huh, impressive - I guess I'm out of date (and/or the people I listen to about such things have a working XRF already and don't want to replace a working unit).

On the individual scale, something like a Sigma Metalytics resistivity analyser (passes an electric field through the sample, checks to see if resistivity, conductivity, weight or …

I don't think it's a dumb question, though I guess some might question its relevance. Side-comments can be interesting, though. I don't know why they did it, but it follows the sam…

Three "bad" missiles over a five minute period. The hit on the WCK convoy killed the latest 7 out of over 200 aid workers who have been killed in Gaza since this latest war began.

Do you have a copy of the hardware manual for the thing? If so, I believe the Connections Museum would love to borrow it :)

Yeah, same here: I upgraded to an FP4 about three months ago (from an increasingly-broken-down Samsung Galaxy S9), after puzzling for a while over whether I should wait for what lo…

The thing is, there ARE chunks of spectrum dedicated to digital comms within the amateur radio bands. Here's a link to the VHF band plan we use here in the UK - obviously I can't s…

TBH, I don't have a problem with Rust so much as I have/had a problem with a section of the rust community. The shouting fanbeings of rust put me off looking into it for years, bec…

No, but I see what you mean. Generating hydrogen and methane using electricity will probably never be that efficient, but if you have spare power then using it to get 60% of its en…

Yeah, I'd like to see those figures too, and I think they might surprise you (and me). I don't have figures or references to hand here, but as I understand it modern heat pumps sho…

In the context of heat pumps, a "backup heating strip" is a resistive heating element - electricity goes in, heat comes out just like an old electric heater. They're generally used…

I always forget the size difference between US and UK homes (I assume toomuchtodo is speaking from a US perspective). Here, in my three-bedroom UK house I'm on a 60A service fuse a…

"Affordances" are a UI design concept - they're things that the design of an object makes you think you can do with that object, if that makes sense. In this context, door handles …

It is indeed a concern, and I suspect that's why they're recommending any wikihous project include a full-house MVHR system (see About=>Product, the bent arrow near the middle of t…

I really want to see more electric conversion kits for existing cars, I must admit. It seems like such a waste to throw away what is in many cases a perfectly good chassis/geartrai…

They're not so much unreliable as ... really not very sensitive, as I understand it. Viral load in covid sufferers follows a curve with a rapid ramp up and a slower ramp down, both…

Most air-tight houses have an integrated MVHR (mechanical ventilation with heat recovery) system, which is kind of the inverse of an HVAC setup. There's a constant small air curren…

pv == photovoltaics - rooftop solar panels, in this case.

Correct, the British Royal Air Force.

Looks like that trial's currently not accepting new participants, but thanks for the link - I'll keep an eye on it in case that changes. The retrofit plan that an eco-retrofit arch…
