Breaking the Cylinders of Excellence – 15, 16, 17 Nov


Nobody interacts with government because they want to – they interact with government because they have to, and most people come away from online interactions feeling more confused than when they started.

That’s why the Digital Transformation Office (now the Digital Transformation Agency) was created in 2015 – to change the way government delivers services, by relentlessly focusing all delivery activities on user needs, and modernising technical delivery methods.

In this talk we’ll learn about the problems with the traditional approach to digital service delivery in government, the cultural and structural barriers to changing service delivery in government, and how Open Source platforms, APIs, and Continuous Delivery enable the DTA to help government deliver simpler, clearer, faster public services.



Lindsay Holmwood is a engineering manager living in the Australian Blue Mountains. Lindsay works at the Australian Government’s Digital Transformation Office, building clearer, simpler, faster, more humane public services . A long-time contributor to the open source and DevOps communities, he authored cucumber-nagios, Visage, and Flapjack, and has run the Sydney DevOps meetup the past five years.

Lindsay speaks internationally about both the cultural and technical side of DevOps, covering Just Culture, complexity, cognitive biases, and monitoring tools. He also won third place at the 1996 Sydney Royal Easter Show LEGO building competition. You can find Lindsay on Twitter @auxesis, and read his blog at

YOW! Night Hong Kong – Martin Thompson – 28 Nov


What does it really mean to design software for high-performance? Performance is such a generic and misunderstood subject. In this talk the subject of software performance will be explored. We will focus on what is means to achieve sufficient response times, throughput, and scalability.

Why do we confuse latency and response time? Once the theory is out of the way we will dig into how modern hardware works and what we need to know about abstractions mapping to our software designs. These abstractions are the key to the models our code represents. The speaker has not meet many abstraction layers he did not enjoyed violating. There is a good reason for this. So many of our abstractions are leaky or just plain wrong.



Martin is a Java Champion with over 2 decades of experience building complex and high-performance computing systems. He is most recently known for his work on Aeron and SBE. Previously at LMAX he was the co-founder and CTO when he created the Disruptor. Prior to LMAX Martin worked for Betfair, three different content companies wrestling with the world largest product catalogues, and was a lead on some of the most significant C++ and Java systems of the 1990s in the automotive and finance domains.

He blogs at, and can be found giving training courses on performance and concurrency when he is not cutting code to make systems better.
