Presentation Summary

23 years ago, the Java Virtual Machine promised to free programmers from the error-prone drudgery of memory management and the frustrations of maintaining code-bases for multiple operating systems. Alas, the large memory requirements and long start-up times of early JVM versions gave Java the reputation for being "slow." The reputation lingers despite Just-in-Time compilation and two decades of optimisation and performance-tuning. This presentation will focus on some of the most recent changes to the VM to trim down and speed up apps. We will also talk about the high-performance GraalVM that can support multiple languages at once. Depending on time/interest, we might also look at Quarkus.

Presentation Summary

In the ever-evolving world of Development and Operations, more and more companies are adopting a DevOps methodology. This puts more responsibility on everyone to develop with security in mind. This includes securing your cloud infrastructure. In this session, we will discuss methods and best practices to run your product responsibly in Amazon Web Services (recognizing that these practices can also be adapted for other public cloud offerings). We will look at different tools to manage your infrastructure and security in code and what tools AWS offers to monitor the security of your infrastructure.

Presentation Summary

Did you know that you can take code written in languages like C, Rust, Python, and Go (to name a few) and compile them to a technology that runs in all modern web browsers side-by-side with JavaScript?
In this session, you'll learn about WebAssembly:  What is it, what problems it solves, how it works, and what makes it secure. That last point about security is important because that's one area that gives many people pause when hearing the words "native code" or that C++ can be used. Immediately, we have flash-backs to plugins and pointers.
In this session, you'll also learn how to create a WebAssembly module and how to interact with it. Because WebAssembly modules are not limited to the browser, you'll see how to make use of the same module in NodeJS.
To round out this session, you'll see that WebAssembly modules are not a way to hide your code. You'll also see what options are available to debug a WebAssembly module.

Michael Go:  Introduction to Artificial Neural Networks with Back-Propagation

For A.I. application development, we commonly use Tensorflow or Keras. In this session, we will do a step-by-step tutorial on how those neural network libraries work and learn how back propagation works. Also, we will cover the advantage(s) and disadvantage(s) of using a neural network with back-propagation.
