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

[–] [email protected] 8 points 2 days ago* (last edited 22 hours ago)

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

[–] [email protected] 15 points 2 days ago

Yeah this part really confused me

Oh so computers are doing carcinization now as well

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.

Dehydrate!

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

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

The first one

[–] [email protected] 6 points 2 days ago

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

Also in Adrian Tchaikovsky's "Children of Time" and the following books!

[–] [email protected] 17 points 2 days 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?

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

[–] [email protected] 7 points 2 days ago

not A crab, no.

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.

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!

[–] [email protected] 2 points 2 days ago

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

[–] [email protected] 1 points 2 days ago

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

[–] [email protected] 11 points 3 days ago

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

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

If the logic gates can feed back onto themselves, you can build a simple [flip flop](https://en.m.wikipedia.org/wiki/Flip-flop_(electronics)) that can store a bit.

[–] [email protected] 6 points 2 days ago

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

[–] [email protected] 4 points 2 days ago

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

[–] [email protected] 10 points 3 days ago (1 children)

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

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

[–] [email protected] 5 points 3 days ago (1 children)

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

[–] [email protected] 4 points 2 days ago

How do you overclock the crabs? Hot butter?

[–] [email protected] 10 points 2 days 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

[–] [email protected] 6 points 3 days 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.

[–] [email protected] 8 points 3 days 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.

[–] [email protected] 4 points 3 days 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.

[–] [email protected] 4 points 2 days 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.

[–] [email protected] 2 points 2 days ago

Why 640 thousand?

It should be enough for anyone.
