Am I correct in saying this is the highest possible packing efficiency for planting as much sugarcane as possible within a single chunk?

The pattern consists of 5 block + shapes with the central block replaced with a water source. This will tile the plane with a theoretical efficiency of 80%

When limiting the pattern to a single chunk, we lose 3 plantable tiles per edge, with the exception of the bottom left corner, where one of 2 adjacent 'dead' tiles can be replaced with a water source to save the other.

I count 52 water sources and 10 'dead' tiles, making the packing efficiency (256 - 52 - 10) / 256 = 75.78125%

EDIT: It looks like I missed an 11th dead tile in the bottom right corner, which brings the efficiency down to 75.390625%

EDIT 2: This paper https://www.researchgate.net/figure/Minimum-dominating-sets-of-square-grid-graphs-for-1-n-14_fig2_220342276 (paywalled unfortunately) explores the same concept in mathematics. They were able to use 60 'water sources' in order to end up with 0 'dead tiles' for a total efficiency of 76.65625%

I just made a shulker farm in creative to make sure it worked before actually making it. I'm new to Java and it was my first time making this type of farm, it was not fun. I'm still learning redstone/farm making so I have a few questions on how it work:

1. What's the purpose of the top layer that's sticking out? (Reminds me of a candle)

2. There's an observer that triggers a piston that pushes the shulkers. It's located right next to the column in the center. Is that where the duplication happens? Or is it the layer where the boat are since the shulkers are facing each other and throwing projectiles?

3. There are also rails being place on the second-to-top layer. And also powered rails in the same layer. What are the purpose of those?

I am following Adil Gamez build

the server is on hypixel smp. java 26.1.2. only mod used is sodium on fabric api. design is based from a Raysworks video. client light level when standing on the platforms is 0 (0 sky, 0 block). platform seems to be in the correct place. One witch did spawn on the bottom platform when building the farm. snow golems are unharmed after afking for ~2 hours.

I`m playing on a 1.21.5 Server (with mods if its relevant) with Friends and over the years i built, or moreso copied from tutorials, all kinds of Storagesystems. This time i wanna go all out and build a big Hall for Major Storage capacity just to have the space available if i ever need it. I googled around and watched a couple videos but it seems like theres many coponents like loaders and unloaders and these tutorials dont even include the Item Input or Overflows or anything you typically need in a Storage System.
Is there maybe a fixed design that includes everything necessary?
Redstone doesnt really stay in my head so i usually just copy from videos but this one stumps me already in the planning stage.
Any help is appreciated.

To sum up what i would want in this Hall:
-Loader and Unloader so Shulkers are readily available when i stand infront of it.

-General Item Input so i can throw my inventory, or even filled Shulkerboxes into that the systems funnels into the correct Section.

-if possible to fit in; a option to get small amounts of an Item so i dont have to get a full shulker every time that i then have to throw back in the system again

-a way to connect the left side with the right side to make it a single system, because the Wall opposite of the Entry will have a big Vault Door for more personal/valuable Storage

It feels like a big ask but i wanna step up my game with this

I see many technical players use it that’s why I’m asking here.

I made this myself without a tutorial, added in the villagers with a zombie to the left of them (stuck in a 1 block hole) but nothing is spawning. is there anyone who knows whats wrong?

Basically my friend hid a book inside a chest within our world and I'm wondering if there is any mod, method, or just way to actually find it. The only hint I have is a picture of him over an ocean with a mossy cobble block in the ocean, but thats really it. Any help will be appreciated he said he would doordash me for the next month if I can find it.

i just added an auto crafter and the items from blast furnace that gets transferred into the hopper wont go into the chest
