FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Internet Scale Services Checklist

Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

Basic tenets

  • Does the design expect failures to happen regularly and handle them gracefully?
  • Have we kept things as simple as possible?

Takes a URL to the ascii output of opentsdb and outputs json in a format easily used by the NVD3.js graph library (at least lineWithFocusChart) Will probably build on this to create a nicer frontend / dashboard NVD3 (http://nvd3.org/) - D3 js library OpenTSDB (http://opentsdb.net/) - Metric collection tool

Which of these is the fastest?
x = 10000.times.to_a
a,b,c = x.dup, x.dup, x.dup
Benchmark.measure { 1000.times { out = []; out += a; out += b; out +=c; out.uniq! } }
Benchmark.measure { 1000.times { out = Set.new; out += a; out += b; out +=c; } }
Benchmark.measure { 1000.times { out = {}; a.each {|e| out[e] ||= 1}; b.each {|e| out[e] ||= 1}; c.each {|e| out[e] ||= 1}; } }

blog: rust pollymorpism

EDIT! full code can be found here gist

So I played around with rust a bit now. And I thought I might share some random stuff.

So say you wanted to represent a expression tree with plus and minus nodes and a node for values. One way to do this would be to use rust's enum's.

In rust enums are like haskell's union types so you can specify the different values to be constructors carrying data.
