EPIGRAMS IN PROGRAMMING

1. One man's constant is another man's variable.

2. Functions delay binding; data structures induce binding. Moral: Structure data late in the programming process.

3. Syntactic sugar causes cancer of the semicolon.

Listen Poller

Overview

The listen poller is a poller that allows external sources to record metrics through a single shh instance. This means that any process that can produce output, can record metrics through shh. While this is happening, shh can concurrently collect and publish it's own metrics (from other pollers).

Ricon 2014 Notes

Keynote: Marten Mickos (SVP and General Manager, HP Cloud): Open Source Wins

Started with RDBMSes and needed to “scale out”.

• Why? Well, we couldn’t scale up anymore. (talking about MySQL)

Composibility of simple components

Distributed (not monolithic)

Design for failure (Assume everything is always going to fail)

• Shift in trust. (> more reliable)
