Technology - Scala, Play, Akka, Spray

Timing is everything. If a system does not respond in a timely manner then: at best, its value is greatly diminished; and at worst, it is effectively unavailable. Reactive systems need to meet predictable response time guarantees regardless of load or datasets size, even in the presence of burst traffic and partial failure conditions.

In this talk we will explore what is means to be responsive and the fundamental design patterns required to meet predictable response time guarantees. Queueing theory, Little's Law, Amdahl's Law, Universal Scalability Law - we'll cover the good bits. Then we'll explore algorithms that work with these laws to deliver timely responses from our applications no matter what gets thrown at them.

React London 2014: Responsive Trait - Responding in a Timely Manner - Martin Thompson

Jonas Boner asked me to write an abstract for this talk. We were talking about some of the things I'd learned while building resilient systems. I mentioned a few simple things I knew - he said "Tell them these things, stories from real-life experience are always fun"

I sat on the underground, with my notepad out and started scribbling. The planned title of the talk was 7 things I'd learned about programming. But by the time I got to Kista I had a list of 32 things.

By the time I've written the talk it might be more than 32.

So I'll talk about the K things that I've learned where K >= 32

Joe Armstrong - Principal Inventor of Erlang

Joe Armstrong is one of the inventors of Erlang.

When at the Ericsson computer science lab in 1986, he was part of the team who designed and implemented the first version of Erlang. He has written several Erlang books including Programming Erlang Software for a Concurrent World. Joe held the first ever Erlang course and has taught Erlang to hundreds of programmers and held many lectures and keynotes describing the technology.

Joe has a PhD in computer science from the Royal Institute of Technology in Stockholm, Sweden and is an expert in the construction of fault tolerant systems. Joe was the chief software architect of the project which produced the Erlang OTP system.

He has worked as an entrepreneur in one of the first Erlang startups (Bluetail) and has worked for 30 years in industry and research.
