Oh so computers are doing carcinization now as well

There are not 8 logic gates in a byte, there are 8 bits in a byte

[–] vala@lemmy.world 15 points 10 months ago

Yeah this part really confused me

[–] the_tab_key@lemmy.world 8 points 10 months ago* (last edited 10 months ago)

Original is correct If the gate they built with it with is a D-flipflop.

Dehydrate!

(For anyone unfamiliar with it, there’s a similar concept in Cixin Liuβ€˜s Three Body series. Forgot which of the books.)

[–] benignintervention@lemmy.world 15 points 10 months ago

The first one

[–] ouRKaoS@lemmy.today 6 points 10 months ago

One of my coworkers calls taking a piss "Dehydrating" and it has stuck in my head since.

Sentient AI: "OMG I'm a crab?!" Scientist: "Always have been..."

[–] sanpedropeddler@sh.itjust.works 18 points 10 months ago (3 children)

How do you store a tweet in logic gates? Would you not need to construct crab based memory?

And to play doom you would need a crab based cpu with much more functionality than the few logic gates they have working.

[–] enumerator4829@sh.itjust.works 26 points 10 months ago (2 children)

If you can have NAND-gates, a clock and some wires, you can build anything.

Go visit https://nandgame.com/ to try it out yourself!

[–] zqwzzle@lemmy.ca 2 points 10 months ago

Based on the https://nand2tetris.org/ courses if you want an even deeper dive.

[–] daw@feddit.org 1 points 10 months ago

I know what I'll do in the next boring lecture!

[–] splinter@lemm.ee 11 points 10 months ago

You can create memory by arranging logic gates in bistable or latch circuits.

[–] GamingChairModel@lemmy.world 7 points 10 months ago (1 children)

If the logic gates can feed back onto themselves, you can build a simple flip flop that can store a bit.

[–] chellomere@lemmy.world 6 points 10 months ago

Yeah but you need 2 logic gates for one bit so it would take 16 logic gates for a byte, not 8.

[–] Geobloke@lemm.ee 18 points 10 months ago

Too late, Pratchett and Ponder did it with ants, so it's more micro

Also what happens when the crabs die? Does the computer start recycling itself?

[–] umbraroze@lemmy.world 12 points 10 months ago

Some people may be asking "is that a bit too many crabs?"

The answer is that it's an adequate amount of crabs. For that task at least.

[–] ICastFist@programming.dev 10 points 10 months ago (1 children)

Do we need any more proof that crabs are indeed the ultimate lifeform?

[–] GenderNeutralBro@lemmy.sdf.org 8 points 10 months ago (1 children)
[–] peoplebeproblems@midwest.social 10 points 10 months ago

when two swarms of crabs collide, they merge and continue in a direction that is the sum of their velocities.

Hahahahahaha. I love nature

[–] Ilovethebomb@lemm.ee 8 points 10 months ago (1 children)
[–] molten@lemmy.world 9 points 10 months ago (1 children)

I'm not doing that math. One every 6 hours.

[–] ICastFist@programming.dev 5 points 10 months ago (1 children)

What if you overclock the crabs? Surely you could reach 1 per hour!

[–] molten@lemmy.world 4 points 10 months ago

How do you overclock the crabs? Hot butter?

[–] LodeMike@lemmy.today 6 points 10 months ago (2 children)

Why 640 thousand? You mean store and retrieve? Because 240 UTF-8 chars is 240*64= maximum just over 15 thousand bits.

[–] xthexder@l.sw0.com 8 points 10 months ago (1 children)

It also equates 1 bit to 1 logic gate, which I'm not sure it's possible to create memory using that few gates unless it's read-only. All memory cell circuits I know of require at least 2 logic gates.

[–] alt_xa_23@lemmy.world 4 points 10 months ago (1 children)

DRAM needs 1 transistor per cell, but it loses stored data quickly, and a crab-based computer would probably be too slow to update it.

[–] xthexder@l.sw0.com 4 points 10 months ago

Ah right. DRAM also requires a capacitor instead though, and I don't know how you'd represent that with crabs. Maybe it's possible.

[–] Ensign_Crab@lemmy.world 2 points 10 months ago

Why 640 thousand?

It should be enough for anyone.

[–] MonkderVierte@lemmy.ml 4 points 10 months ago

They were too engrossed in if they could, to condsider if they should.
