The Diabolical Developer's Guide to Performance Tuning by Martin Verburg
The Diabolical Developer shows you the steps to take when you get a call at 3:00am saying that your Java / JVM application is too slow. He introduces the Performance Diagnostic Methodology (PDM) which focuses on how to quickly hone into the root cause of a bottleneck and what steps you can take to fix it. After this session you should only have to take hours, instead of days or weeks to pinpoint performance issues in your apps.
The JVM as a Platform for Building Smart Contracts by Ben Evans
In this talk, Ben will introduce some fundamentals of cryptocurrency, before diving deep into Java bytecode and classloading, to discuss a new way to make the JVM environment suitable for running 'smart contracts'. These contracts have applications to distributed cryptographic ledgers, blockchains and cryptocurrencies. Ben will then introduce a real example based on R3's Corda ledger (part of the Hyperledger project) and discuss some future directions and practical applications.
Developers who are interested in learning more about the JVM's bytecode and classloading subsystems should attend. No previous knowledge or experience of distributed ledgers, cryptocurrency or blockchains is required.
Meetups in TechMeeetp.Space are designed to enhance the technical knowledge of attendees, and due to the overwhelming demand to attend our events they are always full.
