"I'm working on my masters and I feel like such a dumbass..."
Never assume someone with an advanced degree knows anything outside of that degree because "they must be smart".

There is a difference between "intelligent" and "smart" is the way I like to describe myself.
I'm college educated. But I'm also the guy that took twelve years to realize that his stove had a cook-timer on it...

I worked with someone who was working on his second PhD in computer science and the guy did not know how to print.
Literally couldn't figure out how to click the print button.
In computer science.
PhD.
Computers.
I've worked in tech for almost 20 years. A big misconception is confusing Computer Science and IT. Computer Science is generally more about logic, data structures, and programming paradigms across languages. IT is generally more about the configuration, deployment and usage of technology and operating systems for end users.
There's a ton of nuance in there, like Infrastructure or devops, where it's about the deployment of technology software and hardware to power large technology services, which sits in the middle.
That being said, I've generally found that the more specialized someone is in computer science, the less they know about the operating system they use and how it works. Especially if they spent the time to go for a PhD or something.
The smartest programmer I've ever met is my boss, our CTO. PhD from an Ivy League school. Can write haskell on a napkin, even though our stack doesn't touch haskell. Also doesn't know shit about how MacOS works even though he uses a Mac, and consistently asks me relatively simple questions regarding unix/linux differences, filesystem stuff, package managers, etc. It's very interesting to see the difference in knowledge.
You can tell he is smart because he asks you about stuff outside of his domain.

Absolutely. I'm a tech, hubs is a dev. Brilliant dev, one of the foremost specialists in my country.
Can't build a pc for shit, can't fix a network issue, screams for wifey when the printer's being a dick :D

Honestly, speaking as somebody with two different masters degrees, it’s a good idea to not assume they know anything WITHIN their degree field too, until they prove otherwise.

I'm so thrown off by our current shower which legit heats up in 2 seconds. I was so used to waiting like a minute for it to warm up, I built my rituals around that. But this one... it's just hot, like right away. Bizarre
In fancy installs, the hot water supply is a loop, not a tree, and a circulating pump keeps the entire run hot.
That sounds like a great way to waste energy.
Sorry, you've met wealthy people, right...?
It's just dumb engineering to heat up a pipe the entire day for the 0.8% of the day you need it to be hot.
Insulation + retaining heat means it isn't nearly as energy inefficient as you think.
They keep the water tanks heated all day, and not heating the pipes means they have to do more work as they are drained of more water to fill the length of pipe to the shower which will then lose that heat over the course the day, only to need the water heater to heat it back up again.
With enough insulation, anything can meet energy-efficiency standards. XD

Someone else already pointed out that these are usually pretty well insulated systems that don't radiate much energy, but also consider how many dozens of gallons of water aren't being wasted by waiting for it to be warm.

If you have a hot water tank, that hot water is just sitting there getting cold just waiting to be heated up again. A circulating pump puts that hot water to use by circulating it through the pipes, which has a nice side effect in cold climates of preventing the pipes from freezing and bursting. I doubt it wastes much energy as you think.

The distance from the heater to the shower is usually the biggest factor.
Same here! Moved to an appartement so everything is closer and now I don't need to turn on the shower 5 business days before I want to shower

Parenting. You think you’re doing great and you realise at times that some of the thing a you take for granted, you haven’t taught your kids.
Just because they’ve seen you do something a thousand times doesn’t mean they understand why
As a parent, I was surprised at the amount of stuff kids need to be taught. Stuff that I assumed was obvious isn't - it's learned behaviour. And you don't realize that it's learned until you see your kid struggling with some trivial task.
As an ex kid, I only recently realised my parents taught me almost nothing. Even though I later learned a lot of very varied things, I could have started much better equipped for life. To people who chose to have kids, don't be like my parents. It's really crippling.
The fun part is watching your kids figure out complex and nuanced things that you never even thought about, much less understood, while struggling with those trivial tasks.
OMG yes! One of my kids I have to micromanage to brush their teeth but is like Deanna Troi when it comes to their friends. (I’m more Data)

I remember a story of a child watching their mother cook a roast, and asked why she cut the ends off before putting it in the oven.
The mother learned it from her mother, so they both went and asked the grandmother.
Turned out the grandmother used to have a small oven and did that to make it fit.

when I was little I would wait for the water to warm up, then pull the thing to turn on the shower head. But there's like 2 seconds of freezing water in the tube to the shower head so I would have to really quickly pull it, run back to the edge of the shower, and block it with the shower curtain. It had a 50% chance of failure and I did it for years
I learnt that there’s a bit of cold water when switching to the shower head the hard way.
Pointed it at my wife and swapped it and she screamed. Whoops lol.

I remember this thread. One of the responses was from someone who thought that the beep his car made when locking the doors got quieter when activated from further away.
Well...by the power of the inverse square law, they kinda do, I guess.

We had a guy at work a couple years ago, nice guy but not too bright. He'd fill his bottle from the water cooler, and always got surprised by how fast it filled up at the top. He thought the water cooler's dispenser somehow got faster as the bottle filled up, not realizing that it's because the top of the bottle is narrower than the bottom.

You're not supposed to just stand there and waste that warming-up water, you're supposed to collect it in a watering can and put it on your plants! It's got stuff from having sat in the water heater so it's not the best for drinking but plants don't mind.
This legitimately is something I've been looking for as I hate just running a gallon of water out for no reason.

I lived the same "realization moment" last year talking to a friend.
I was saying that I need to go home to wash my white undershirts as I only got blacks left (small t-shirt to wear under a shirt and not freeze to death during winter).
He asked me why so I have several colors of undershirts.
Well, black and grey for black or dark colored shirts, white for white or clear colored shirts otherwise you’ll see it behind the fabric, duuuh, are you dumb?
The answer:
Or you can wear white ones under dark shirts as well and it won’t be visible…
🤔🤔🤔😧 FFS dude, why did I never thought of that?
I wish the same were true for bras. Women's shirts are often much thinner than men's, so a white bra might show through a dark shirt. It took me until this year to figure out that in order to make your bras less visible under light or white shirts, you should use a skin-tone bra instead of a white bra. Blew my mind when I figured that one out.

You can sometimes see the white collar part, unless that's just it being weird how it sits on me.

I can understand the shower one, but who tf is insane enough to not use oven mitts or a rag? I'd imagine you'd take a moment to think about the possible solutions before doing something that painful
It's an analogy, not real life.

I didn’t learn until my 40s that if you exhale gently while getting water on your face, none of it goes in your nose.
I think I learnt this when I was taught swimming as a child. You always slowly exhale or at least keep the air in your nose slightly under pressure while you're underwater, so the water doesn't get in.

So he's about to have shower sex and he is capable of thinking about anything else?
why would they have shower sex, when they could have sex then shower
Yeah, shower sex might be one of the most overrated things I know. It always feels like a good idea at first and then you quickly realize that the logistics of it are hell

No one mentioned (probably an assumed thing) to turn the water on full hot to let it warm up, then move it to the preferred mix position. Doesn't waste the cold water which will stay more or less the same temp, it's only flushing out the cold in the hot water line. And because you have it fully on hot, it takes less time.
Or get a tankless water heater to get it almost right away. I've seen debates on which is a better choice when factoring everything in, and I think it's a close tie with no clear winner, each having their caveats.
