Douglas Hawkins
Lone Star Software Symposium: Dallas
Dallas · May 29 - 31, 2015
Lead Developer Java Performance Monitoring at Datadog
Douglas Hawkins has been passionately developing software for the past 20 years.
Throughout Doug's career, he has focused on creating performance intensive applications
in Java ranging from bioinformatics to financial exchanges.
After 10 years as a Java developer, Doug transitioned to working on Azul's Java Virtual Machine.
Today, Doug continues his interest in building performance tools for developers working on Datadog's Java Application Performance Monitoring.
While Doug's passion for developing software remains, his true passion is in sharing his
interest in low-level details and JVM performance with others.
Presentations
How (Not) To Measure and Profile Java Performance
Today, we all benefit from the sophistication of modern compilers and hardware, but that extra complexity can also make it difficult to reason about performance.
How a Compiler Works -- and Why It Matters to You
To write efficient SQL, you need to understand SQL execution plans. And to write efficient Java, you need to understand the JVM's execution plan.
Concurrency Concepts in Java
Unlike other languages, Java had a well-defined memory model from the very beginning, but over the years additional packages and low-level features have been added to make the most of today's hardware.
In this talk, we'll discuss concurrency in detail starting at the hardware up to Java's latest synchronization mechanisms and finally onto high-level concurrent collections.
