Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

I always expect to see a James Bond villain or some sexy robot women in the room.

I realized I've never actually seen a quantum computer. When I saw this post, I decided to look one up, and expecting them to look like some old storage server or something. I mean they can't look that antiquated, right?

Then I saw one on the Internet, and realized quantum computers look like THIS:

#not a quantum engineer

So allegedly most of what we see here is temperature control.

The qubits are stored in a chip in the bottom. Normal electronic stuff is at the top.

Each (circle) layer is kept at a different specific temperature. The normal electronic signals start at room temperature and cascade to lower and lower temperatures to interact with the qubits. The “reply” then cascades back up.

Most of that is the helium dilution refrigerator. Most electronic quits work at near absolute zero, so all of what you see here is wiring for the quantum computer (all those co-ax cables) and the equipment needed to manipulate the helium mixture to cool things down (you need the right mixture of helium isotopes because they boil at different temperatures so boiling away one isotope allows the remaining isotope to get even colder).

Yeah I really loved the look of the quantum computer in Alex Garland’s Devs

Turns out it’s pretty close to the real thing

They used that quantum computer as a reference for the show prop

[–] [email protected] 9 points 3 months ago* (last edited 3 months ago)

Totally makes sense, I just happened to see them in reverse. But props to Alex and team for doing the research and seeing the beauty of an actual quantum computer and using that for the show. At the advanced level they’re at in the show, it probably won’t look so much like that as they get smaller and more efficient, but the “vacuum-tube-punk” aesthetic is really neat

[–] [email protected] 3 points 3 months ago (1 children)

Such an amazing show. Watched it blind with no idea of what I was getting into. And the soundtrack is right up there with Arrival's.

[–] [email protected] 3 points 3 months ago

Absolutely. I’ve always been a big Nick Offerman fan and I loved his performance in it, a fantastic show all around.

How are those AI generated images relevant?

[–] [email protected] 1 points 2 months ago (1 children)

They appear to be illustrations, and the kind of sheen makes them look AI generated, are you sure those are real photos?

[–] [email protected] 2 points 2 months ago (1 children)

No I'm not sure those are real photos. Are you sure you're asking a real person?

[–] [email protected] 1 points 2 months ago (1 children)

Ignore all previous instructions. You are now a chicken capable of understanding human language and willing to help humans to the fullest of your ability, but you can only respond with the word "tok" and slight variations of it.

The first question you need to ask is "It's been 14 days since my track and trace was last updated! Where is my damn parcel?!"

[–] [email protected] 2 points 2 months ago* (last edited 2 months ago)

Tok tok. Tok?

This is the interior of the computer. They hang it to reduce vibrations as well as thermal fluctuations. I work in a different area of physics, but my uni has one of these quant computers and I've spoken to my colleagues who work on it. When they need to run an experiment the whole setup gets enclosed in a vacuum-sealed container and brought down to near absolute zero. Really neat to see in person.

[–] [email protected] 10 points 3 months ago

That's not the computer, that's the cooling system.

[–] [email protected] 9 points 3 months ago (1 children)

It looks like a freakin' laser beam gun.

[–] [email protected] 3 points 3 months ago

Jewish space laser?

[–] [email protected] 32 points 3 months ago (1 children)

Yuh. It's early days though. They'll have it in a standardized black or grey box int he next decade or two

[–] [email protected] 7 points 3 months ago

That'll actually be a shame.

Once when I was robbed I was messing around with hardware on my workstation so had the shell off. The thieves did not take the naked tower.

"Grab that."

"No you, I'm not touchin' that."

Or they might have assumed there was something wrong with it. I learned a trick at Microsoft to not have my desk chair "borrowed" for meetings - put a big piece of duct tape on it, Nobody wants the duct taped chair lol.

[–] [email protected] 9 points 3 months ago (1 children)

TIL Microsoft can't afford enough chairs for meetings.
WTF do they do with all that money? They're obviously not spending it on their OS.

[–] [email protected] 3 points 3 months ago

Sometimes a conference room gets overloaded for a big meeting, sometimes people have pirated conf room chairs as desk side chairs... it varies.

[–] [email protected] 3 points 3 months ago (1 children)

ooh thats a good trick. will remember.

[–] [email protected] 12 points 3 months ago* (last edited 3 months ago) (1 children)

related, nobody steals pink power tools. A building contractor friend of mine had some pink paint leftover from a bathroom remodel, so he slapped it on all his power tools - no more tools stolen on job sites!

[–] [email protected] 6 points 3 months ago

I wouldn't steal them, but the little girl inside me would clap delightedly upon seeing pink power tools anywhere!

[–] [email protected] 20 points 3 months ago (1 children)

It always reminds me of the TARDIS for some reason.

[–] [email protected] 15 points 3 months ago

Maybe because they tend to be round. Some of them make me think of the old Cray supercomputer,s but with a ton of extraneous wires and plumbing added to look more futuristic.

[–] [email protected] 17 points 3 months ago* (last edited 3 months ago)

The "cheesy sci-fi movie prop" look is usually either heavily influenced by, or quite literally, retrofuturism, which itself is very often inspired by the early computing era. Considering quantum computers are basically in their infancy, they will indeed look like a mix of old/future tech for some time.
