user: Given this reference text about the Koala, tell me what makes up most of their diet, how long joeys spend in their mothers' pouches and what are some of the pathogens they are threatened by.

The koala or, inaccurately, koala bear (Phascolarctos cinereus), is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae and its closest living relatives are the wombats. The koala is found in coastal areas of the mainland's eastern and southern regions, inhabiting Queensland, New South Wales, Victoria, and South Australia. It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, spoon-shaped nose. The koala has a body length of 60–85 cm (24–33 in) and weighs 4–15 kg (9–33 lb). Fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations possibly are separate subspecies, but this is disputed.

Koalas typically inhabit open Eucalyptus woodland, as the leaves of these trees make up most of their diet. This eucalypt diet has low nutritional and caloric content and contains toxins that deter most other mammals from feeding on it. Koalas are largely sedentary and sleep up to twenty hours a day. They are asocial animals, and bonding exists only between mothers and dependent offspring. Adult males communicate with loud bellows that intimidate rivals and attract mates. Males mark their presence with secretions from scent glands located on their chests. Being marsupials, koalas give birth to underdeveloped young that crawl into their mothers' pouches, where they stay for the first six to seven months of their lives. These young koalas, known as joeys, are fully weaned around a year old. Koalas have few natural predators and parasites, but are threatened by various pathogens, such as Chlamydiaceae bacteria and koala retrovirus.</think>

user: What is Humanism?

assistant: Humanism is a belief system that emphasizes the power of the human individual rather than any god or other divinity. Humanists believe in the innate goodness of human beings, the inherent capacity of humans to care about each other, and it stresses the rational in explaining the world around us.  It is a belief system for those who cannot embrace the supernatural and prefer instead to reside in the actual world and try to understand it with scientific explanations. Humanists use facts, reasoning, and empathy to make decisions. Some others call Humanism 'Good without god'. Humanists aren't openly hostile or antagonistic towards organized religions, but instead they respect that everyone has the right to their own beliefs.

user: Why isn't multi-threading making my Python code faster? How can I fix it.

assistant: Python restricts access to the interpreter with a Global Interpreter Lock, referred to as the GIL, for internal thread-safety requirements. Unfortunately, this design decision restricts only allows one thread to interpret Python code at a time, even on a machine with the capability to run multiple threads together. 

If you wish to run Python code on a set of data, and the data can be broken up into independent segments (a process known as data partitioning), you may wish to look into the multiprocessing library in Python. 

As an example, consider the function foo which takes one argument, arg1, and say you wanted to run the foo function on a number of values, say, val1, val2, and val3.

def foo(arg1):
  # do something

if __name__ == '__main__':
  foo(val1)
  foo(val2)
  foo(val3)

To have foo execute on multiple processes together, you could use the multiprocessing Pool  to run multiple worker processes together:

from multiprocessing import Pool

def foo(arg1):
  # do something

if __name__ == '__main__':
  p = Pool()
  p.map(foo, [val1, val2, val3])

The multiprocessing library also provides various other APIs for parallel programming. Would you like to know more?
