Elasticsearch: updating the mappings and settings of an existing index

Note: This was written using elasticsearch 0.9.

Elasticsearch will automatically create an index (with basic settings and mappings) for you if you post a first document:

$ curl -X POST 'http://localhost:9200/thegame/weapons/1' -d \

Life is purposeless. And it is beautiful that it is purposeless

It is very difficult, particularly for the Western mind, to understand that life is purposeless. And it is beautiful that it is purposeless. If it is purposeful then the whole thing becomes absurd – then who will decide the purpose? Then some God has to be conceived who decides the purpose, and then human beings become just puppets; then no freedom is possible. And if there is some purpose then life becomes businesslike, it cannot be ecstatic.

The West has been thinking in terms of purpose, but the East has been thinking in terms of purposelessness. The East says life is not a business, it is a play. And a play has no purpose really, it is nonpurposeful. Or you can say play is its own purpose, to play is enough. Life is not reaching towards some goal, life itself is the goal. It is not evolving towards some ultimate; this very moment, here and now, life is ultimate.

Life as it is, is accepted in the East. It is not moving towards some end, b

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

This is a post by Joel Spolsky. The original post is linked at the bottom.

This is such a common question here and elsewhere that I will attempt to write the world's most canonical answer to this question. Hopefully in the future when someone on answers.onstartups asks how to split up the ownership of their new company, you can simply point to this answer.

The most important principle: Fairness, and the perception of fairness, is much more valuable than owning a large stake. Almost everything that can go wrong in a startup will go wrong, and one of the biggest things that can go wrong is huge, angry, shouting matches between the founders as to who worked harder, who owns more, whose idea was it anyway, etc. That is why I would always rather split a new company 50-50 with a friend than insist on owning 60% because "it was my idea," or because "I was more experienced" or anything else. Why? Because if I split the company 60-40, the company is going to fail when we argue ourselves to death. And if you ju
