A bucket brigade or human chain is a method for transporting items where items are passed from one stationary person to the next.
The method was important in firefighting before the advent of hand pumped fire engines, whereby firefighters would pass buckets to each other to extinguish a blaze. A famous example of this is the Union Fire Company. This technique is still common where using machines to move water, supplies, or other items would be impractical.
This method needs a number of participants sufficient for covering the distance.

A bucket or pail is typically a watertight, vertical cylinder or truncated cone, with an open top and a flat bottom, attached to a semicircular carrying handle called the bail. A common volume is 10 liters (10 dm³).
== HistoryEdit ==
Building materials and solvents have been packaged in large metal pails, but in recent decades plastic buckets have been greatly favored. Plastic buckets have more uses due to the popularity of plastic for food products and the tendency of metal pails to rust.
== Types and usesEdit ==
There are many types of buckets;
A water bucket is used to carry water

I am in my first year of formally learning computer programming in high school (we are using Java). One of the tools we used was Karel J. Robot, which can be downloaded here. Although we finished using Karel after a semester, I felt that there was a lot more I could do with it. I decided to use s...
As far as I know, in US, grip-and-turn style door knobs are still the most popular, as opposed to lever-style handles, which dominate in the rest of the world.
Is there some UX advantage to door knobs that I am not aware of, which is the reason for keeping them around?
Edit:
To clarify the dif...

Residue Number System
This is code-golf
In the vein of large number challenges I thought this one might be interesting.
In this challenge, we will be using the Residue Number System (RNS) to perform addition, subtraction, and multiplication on large integers.
What is the RNS
The RNS is one...
The idea is the same as the usual guess the number game, but roles are switched, you think of a number and the program will have to guess it.
The rules:
The number should be between 1 and 100
The program starts by printing a number, and it should be "smart", i.e. a typical binary search.
You ty...
Challenge
Your submission should consist of 2 or more programs each written in distinct languages. They can be arbitrarily numbered from 1 to k.
Each program p, given a natural number n should print the next n prime numbers (initially, the next prime is the 0-th prime, 2) on a single line, fol...
