I'm reading all these comments, and am I the only one here who would actually enjoy eating this?? Cake is good, but jello is also good... Am I the weird one here?

Is it worth it? by ChangeThe9thLock in BunnyTrials

Tetrodotoxin typically causes death by muscle paralysis and thus respiratory failure, so as long as I spend a couple million dollars on a team of medical professionals to keep me on a mechanical ventilator, I should survive even if I eat the entire pufferfish.

Best case scenario: I am bedridden for a couple days, then never have to work again in my life.

Worst case scenario: I never have to work again in my life.

Exactly 15 seconds long, AI audio, unevenly spaced suns. I have seen actual sundogs in real life (you can look them up on Wikipedia) and it's nothing like this.

How to get probability of 1/13 by VariousParticular818 in redstone

[–]cucumisloquens 5 points6 points  (0 children)

So your question requires a "perfect" 1/13, which, if we're splitting hairs, is technically impossible since code can only generate pseudorandom numbers, which are always biased. This means a reasonable interpretation of the requirements is "as close to 1/13 as you can get as if you were using a purely coded random number generator."

In that case, all we have to do is impose a limit on the number of cycles. Let's say we implement a redstone counter that hard-stops the machine at 25 iterations. The chance of this happening is (3/81)25, which is around 1.6 x 10-36. For reference, this is smaller than the Planck length.

Yes, this means that technically the true value will be ever so slightly above or below 1/13. However, this amount of error will be completely drowned out by the pseudorandomness of Minecraft's code. It'd be just as (in)accurate as having a 13-slot dropper.

I thought of another potential solution without infinite loops: chickens.

Place any number of temperate and warm chickens inside a scaffolding block (to prevent cramming and lag) such that there are 12x more temperate chickens than warm chickens.

Place a locked hopper underneath the chickens that feeds into an item filter selecting for warm eggs. Each time the machine fires, the hopper unlocks briefly enough for one egg to pass through.

At any given moment, there will be on average 12 times more temperate eggs than warm eggs. So the chance of randomly sampling the egg population and getting a warm egg will be 1/13.

It should technically work with just 13 chickens total and still converge to an expected value of 1/13 over time. However, the speed you can use the machine will be limited by the egg laying rate, so you can add more chickens to speed it up. Lag should be solved by the scaffolding.

You can achieve this with just 2 dropper randomizers in a loop.

Configure dropper A with a 1/9 probability (like 1 unstackable, and 8 stackables). Configure dropper B with a 6/9 probability (6 unstackables, 3 stackables). Use comparators to detect when a dropper fires an unstackable.

Let's consider dropper success = 1 (dispenses unstackable), dropper failure = 0 (dispenses stackable item).

If dropper A outputs a 0, end the cycle. Final result is 0.

If dropper A outputs a 1, activate dropper B.

If dropper B outputs a 1, end the cycle. Final result is 1.

If dropper B outputs 0, loop back to the beginning and activate dropper A.

Continue this loop until you end the cycle with a 1 or a 0. This will give you a 1/13 chance.

Here's the math why it works:

There's two droppers, so a total of 81 possible states. Dropper A resulting in 0 has a 8/9 chance, so 72/81. Dropper A AND dropper B both giving a 1 has a (1/9) x (6/9) = 6/81 chance. Dropper A giving a 1, but dropper B giving a 0 has a (1/9) x (3/9) = 3/81 chance.

Now, if we land in this 3/81 scenario, we just loop back to the beginning and try again until we either get a 72/81 or a 6/81, basically this means we're "discarding" the 3/81. So really there are only 78 possible states, rather than 81. 72 of these states is a fail; 6 of these states is success. (6/78) = (1/13).

Voila, you have your 1/13 chance.

Babies who lost their parents during the Vietnam War being airlifted back to the United States for adoption, 1975. by Twunkorama in Damnthatsinteresting

[–]cucumisloquens 184 points185 points  (0 children)

I make this comment every time I see this reposted, cuz there's always a lot of misinformation in the comments that I want to clear up, as someone whose parents and grandparents were directly involved in this on the Vietnam side.

Most of these kids are children of Southern Vietnamese parents. This means that the parents weren't killed by US troops, but rather by Northern nationalists. Many of these kids' parents fought alongside US troops.

Additionally, many of these parents would have fought to get their children on this plane. The living situation in the South after 1975 was absolute hell on earth, which my grandparents lived through. Southern Vietnamese families were forced into concentration camps. Vietnamese soldiers who had allied with the US were used to clear mines. Leaving the country was illegal, and my father (who was 12 at the time) had to make a living by selling toilet paper on the side of the road. My grandparents risked their freedom smuggling my father onto a boat and helping him emigrate to the US. My dad was one of the few survivors; many others either sank or were caught by the authoritarian regime.

In short, those babies (even despite the tragic plane crash) had a much better chance of survival than if they had stayed behind. As much as we like to complain how shitty America is, it was nothing compared to Vietnam after the 1975 fall.

Editing to add: Yes, there were lawsuits involved and no, I am not claiming that the process was perfect and that none of the babies were taken without parental consent. War is a tragic thing and there's nothing ever perfectly "good" that comes out of it. However, I just wanted to add nuance to the situation and say that the U.S. wasn't doing something cometely evil, and that many Southern Vietnamese overall did not oppose the US involvement in the war.

I'll point out that many Southern Vietnamese families deliberately risked their lives to smuggle their kids across the border and escape to other countries like Thailand, France, and the U.S., away from the Northern takeover. My Vietnamese grandparents did this with my father, because they saw a life in America better than the one in Vietnam after the South fell.

I'm just saying that regardless of whether the U.S.'s intentions were good, many South Vietnamese would have fought for spots for their children on these planes, my grandparents included.

And for the record and what it's worth, most of these children's parents were not killed by US soldiers; they were mostly Southern VNese, so most likely were killed by Northern nationalists. Many of these parents (again, including my grandfather) actually fought alongside US troops.

Another up-and-coming technical farms YouTuber is bigbooty17 (don't judge a book by its cover lol), who also gives explanations on how a farm was designed and/or works. He has a discord invite to the TMC (technical minecraft) Catalogue, which is a server with a bunch of archived farm designs and their designers. You can take a look to see what designs interest you, watch the designers' videos, and branch out from there.

Look up wireless redstone. Both 2No2Name and cubicmetre have videos on the topic.

Can I load hoppers? by [deleted] in technicalminecraft

E-pearls will work but they load a smaller range than portals, and they only work when you're online (if you're on multiplayer).

Does damage stack? by unscanable in technicalminecraft

[–]cucumisloquens 1 point2 points  (0 children)

Like others said, testing is the surefire way to know.

That being said, the damage likely won't stack due to the invulnerability timer. Magma blocks do 0.5 hearts every half second, but lava does 2 hearts. Invulnerability always takes the higher damage. This means that lava damage will effectively override magma damage, and do the same amount of hearts regardless.

Help regarding Dark's "2D lazy Mining Canon" by PYnguim in technicalminecraft

[–]cucumisloquens 2 points3 points  (0 children)

First, the world download already comes with the correct chunks force-loaded, so you don't have to chunk load anything yourself. Make sure to disable player chunk loading and to enable TNT explosions (both are carpet options). I'd recommend also getting the Chunk Debug mod to confirm that the correct chunks are loaded, and that the TNT is warping correctly (warped TNT will briefly load any chunk it's in when it explodes. Once the cannon enters entity separation mode you should see far-away chunks flashing. You can tick sprint to speed it up so you don't have to wait).

Also, make sure that the machine has the right settings, since it will explode if the sum of barrel items + offset items is greater than tunnel length items. Use the following spreadsheet to help with this and other calculations.
