The FAA still requires ashtrays in bathrooms interestingly. To avoid those who do smoke there using the trash and causing a fire:

  Regardless of whether smoking is allowed in any other part of the airplane, lavatories must have self-contained, removable ashtrays located conspicuously on or near the entry side of each lavatory door, except that one ashtray may serve more than one lavatory door if the ashtray can be seen readily from the cabin side of each lavatory served

What are the black dots around the map when you zoom in? For instance South-East Wales / Bristol, I see a few black dots that look like they cover shaded areas or something. They also show up at the sites for wind farms, possibly they're the turbines themselves?

Looks great. Interesting to see that a lot of stations are included but without prices.

Note, in brave on linux I can't see the map. Console has a lot of 401 on stadiamaps. But works great in chrome.

> From 2 February 2026, you must submit fuel price updates within 30 minutes of any change.

https://www.gov.uk/guidance/report-your-fuel-prices-and-fore...

So looks as though the requirement to report was only just introduced, hence the considerable missing data.

I happened to be looking at ski boot fitting this morning and came across a web app from fischersports that allows you to measure your feet using your phones camera. Surprise surprise it uses a sheet of A4 paper.

App is about halfway down this page, https://www.fischersports.com/rc4-podium-rd-worldcup-strd/U0... under 'find your size' and is powered by https://volumental.com/

They were supposedly invented in Scotland, and I've not seen them sold in an English fish and chip shop. Go to Scotland however and they're not uncommon.

I don't think that's true, however doordash surely know that some users might think twice if they saw that number separated out.

It hosts user uploaded content I would guess, so presumably the OSA could apply to them.
Sure, it's a different part of the product, but still worrying that it may have happened at all.

Looking at it further though, you're right, this probably wasn't apple's fault.

They did have a bug that corrupted images on import I think? https://news.ycombinator.com/item?id=45274277

So maybe don't fully trust it.

True - how much someone is willing to pay matters. However in a competitive market, companies can’t just charge whatever people will pay. Competitors will undercut them, so prices should eventually align with the cost of production plus a reasonable margin.
Presumably the recommended daily calorie intake figures (and the calculators for these) do to some extent take this into account? i.e. I would imagine they're based on experimentally tested values rather than theoretical energy expenditure.
Re:Decibels Are Ridiculous on Thursday May 22, 2025 @12:28PM (#44063646)
But that's why it's so confusing. Did they purposefully leave off the reference to indicate Watts, or did they mean volts (as I'd guess audio engineers typically do when talking about amplifiers).
Re:Decibels Are Ridiculous on Thursday May 22, 2025 @10:38AM (#44062524)
No, because db is logarithmic. That's the key property that allows you to do addition instead of multiplication. Remember these are ratios here as well.

So the original example in linear units would be: We're reducing the signal by 63% in the this cable, and the gain through this amp is 199.5%, so the output is...

0.63 * 1.995 = 1.26

126% which is 20log10(1.26) db or around 2db.

-4 + 6 = 2 is a little easier to do.

Apparently 42% is visible! Less than I expected.

So around 470 W/m2 visible radiation.

Re:Strain gauge made out of PCB on Sunday May 11, 2025 @07:49AM (#43953151)
I don't think it is. PWM_BIAS is used as the select for the analog switch. High connects COM to B1 (GND) and low connects COM to B0 (BRIDGE_SUPPLY).

It's never as cheap as you think is it! I think fortunately I have most of the other bits lying around. Was planning on putting it in a wooden frame with a matte.

Are you happy with the quality?
