Here, I will post all programs which are too miniscule to have their own topic. I'll add more in the future.

daNoob's Advanced Lumberjack (all the cool kids are making these)

Code:
Spoiler

while turtle.detect() do
  turtle.dig()
  while not turtle.up() do
    turtle.digUp()
  end
end

while turtle.down() do
end

turtle.turnRight()
turtle.turnRight()

for i = 1,16 do
  if turtle.getItemCount(i) > 0 then
    turtle.select(i)
    turtle.drop()
  end
end

turtle.turnLeft()
turtle.turnLeft()

(no pastebin)

That is all for the moment.
