Int and bool walk into a bar

Shouldn't it be a float that goes between 0 and 1 instead of an int. In this situation they'd be the same thing, considering 1 would be max lol.

So you only shower with 1° cold water? Or could the int maybe represent something like 40°C?

You're getting down voted, but you're right lol

Yeah, don't know why people would describe temperature on a 0-1 scale

The temperature handle is either off or maxed out in this scenario. Not the temperature.

I guess there’s not enough water to use a float unless you’re in a bathtub.

I travel a lot and I swear I've never seen the same shower design twice. There's so many different freakin' ways to deliver a stream of water to your head and they nearly all require some level of finessing. I'm assuming it all stems from an 1800s court case about patents but fuck that judge and everyone involved that day

It seems that hotels somehow always install the most obscure and convoluted shower designs. I've never had too much trouble with showers in people's homes, but every time I shower in a hotel room I feel like I'm trying to operate an oddly temperamental steam engine.

How using someone else's shower works:

int temperature = rand()

How it really works:

mpf_t temperature;

::: spoiler If confused... It's arbitrary sized floating precision number provided in LibGMP and you can find more information about mpf_t here. :::

Thermostatic shower mixers are not a thing where you live?

Not common in the US I believe, or at least I haven't heard or seen one of them.

You just gotta "guess" what's correct and then feel the water coming out

In the house I grew up in, you’d also have to hope no one flushed the downstairs toilet. If so, the cold water pressure would suddenly drop, leaving a lot more hot water coming out of the shower head.

I knew this was going to be the link and was imagining the Mozart part at the end

Beethoven's Fifth Symphony, not Mozart.

No ill intent, I just like classical music :)

Also not a problem with a thermostatic mixer. The temperature stays the same, you just get less water pressure for a while.

Weird, they are super common here in the Netherlands. Not expensive either. You just set it to a temperature and it’ll keep it constant.

now I want one

If I'm thinking of the same device, the one I used in Sweden and Norway, it's fantastic. It's in the shower itself, so you don't have to contend with 30m of cold pipes between a less effective water heater and the nozzle.

Yeah, I havent had a problem setting the shower temperature since I live in a house that has one.

Its great.

And then someone comes over who isn’t a programmer and they have to take a shower:

Error: cannot convert “warm” to integer

Instructions

while temperature < comfortable_temperature: temperature += 1

Interpretation

while temperature < freezing: on toggle(temperature += boiling)

Where I live, I have to spend 500 years to either get volcano-like water, or Ice Age water. Moving it one atom completely changes the temperature.

If yours uses a thermal sensing element (not just mixing blind),I've found running it through its full temperature range helps a lot. I suspect limescale and other crap build up on the thermal element. It adds several years on to the life of the mixer. Descaling it would likely also work, but involves removing it from the pipes, to get the cleaner in.

Temperature would never be false so this is pretty stupid
