Redis HLL has a 16 bytes header:

• 8 bytes are used to cache the set cardinality
• 3 are not used
• 4 are used to store the magic "HYLL"
• 1 is used to represent the type of the set (sparse or dense)

struct hllhdr {
 char magic[4]; /* "HYLL" */

/*
Parallel processing with ordered output in Go
(you can use this pattern by importing https://github.com/MarianoGappa/parseq)

This example implementation is useful when the following 3 conditions are true:
1) the rate of input is higher than the rate of output on the system (i.e. it queues up)
2) the processing of input can be parallelised, and overall throughput increases by doing so
3) the order of output of the system needs to respect order of input

- if 1 is false, KISS!

Notes

• This code handles any JS runtime error during rendering React components. Without this handling, once an error occurs, whole component tree is damaged and can't be used at all. With this handling, nothing will be rendered in production environment (error span in dev env.) + in production the error is logged to Sentry (if you are not using it just delete related code)
• This is basicaly a workaround for proposed feature in React core - described in Issue: facebook/react#2461
• Works for all variants of Component creation - React.createClass, extending React.Component and also stateless functional components.
• To get this work, just put this snippet into your entry js file. Then it will work in whole application.
• Also supporting React Hot Reload!

Ideas

• specify custom error renderer (global / per component, e.g. by implementing method renderOnError() in a comp
