SwitchCraft 3 introduction for new players

SC3 is a minecraft server built around computercraft. Apart from CC:Tweaked, Plethora, and a few homebrewed mods, there is not much else in the modpack. This gives the game a very vanilla+ feel which manages to have a rather extended endgame due to progression not being the main focus. You probably joined for the computercraft mod, and this tutorial will get to it eventually, but first let me introduce you to all (most) of the new items from all of the mods:

1. Computers

• Computers: Blocks that execute arbitrary Lua code.

Rules:

1. You will be given the coordinates of the cache (aka. chest), but they will intentionally be slightly (or not so slightly) wrong. The coordinates listings will be paired with a measure of how accurate they are. (measured using chebyshev distance)

Example:
Listed coords: 100 69 420 (10 blocks accuracy)
Actual coords: 97 79 412

2. While searching you are not allowed to use a block scanner, chorus fruit, ender pearls, or break blocks, unless the cache specifies you may do so.

How to use this gist

You've got two main options:

MasonGulu

--- Inventory Abstraction Library
-- Inventory Peripheral API compatible library that caches the contents of chests, and allows for very fast transfers of items between AbstractInventory objects.
-- Transfers can occur from slot to slot, or by item name and nbt data.
-- This can also transfer to / from normal inventories, just pass in the peripheral name.
-- Use {optimal=false} to transfer to / from non-inventory peripherals.

-- Now you can wrap arbritrary slot ranges
-- To do so, rather than passing in the inventory name when constructing (or adding/removing inventories)
-- you simply pass in a table of the following format
-- {name: string, minSlot: integer?, maxSlot: integer?, slots: integer[]?}

On Writing a ComputerCraft OS

One of the most common projects I've seen for ComputerCraft is to write an operating system. People look at the limited command-line interface that CraftOS provides, and think, "I want this to work like my normal computer does!" Time and time again, a new post pops up on the ComputerCraft forums or Discord either announcing an OS, or asking for help with an OS, or releasing an OS. Usually, there are some very obvious flaws in these "OS"es, ranging from poor design choices, to overstating what they are and underdelivering. There are many common misunderstandings and undersights that newbie developers run into when writing an operating system, and these end up creating mediocre products at best.

A Critical Distinction

The term "OS" is thrown around a lot, and in my opinion it's very overused. According to [Wikipedia]: "An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs." However, m

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).

Commit Message Guidelines

Short (72 chars or less) summary

More detailed explanatory text. Wrap it to 72 characters. The blank
line separating the summary from the body is critical (unless you omit
the body entirely).

Write your commit message in the imperative: "Fix bug" and not "Fixed
bug" or "Fixes bug." This convention matches up with commit messages
