This document provides an overview of using the Native Development Kit (NDK) to incorporate C/C++ code into an Android application. It discusses installing the NDK tools, writing C code and placing it in the project's jni folder, building the C code into a shared library, and calling the native functions from Java using the Java Native Interface (JNI). The goal is to leverage C/C++ for performance-critical parts of the app or to port existing code to Android.
Multiplatform C++ on the Web with EmscriptenChad Austin
IMVU is using Emscripten to bring its multiplatform C++ codebase to web browsers with HTML5 and WebGL. See how Emscripten works, how to use, and what you can expect.
In the session we reviewed what is micro-service and how to host and deploy them on AWS using Docker. Also we learned why we did not user AWS Lambda (serverless)
Scala macro is the feature introduced in scala version 2.10, and have an experimental status for now. They are the piece of code that is executed at compile-time. Macro definitions are similar to the normal functions except that the body of these functions starts with keyword macro.

Lightbend Lagom: Microservices Just Rightmircodotta
Microservices architecture are becoming a de-facto industry standard, but are you satisfied with the current state of the art? We are not, as we believe that building microservices today is more challenging than it should be. Lagom is here to take on this challenge. First, Lagom is opinionated and it will take some of the hard decisions for you, guiding you to produce microservices that adheres to the Reactive tenents. Second, Lagom was built from the ground up around you, the developer, to push your productivity to the next level. If you are familiar with the Play Framework's development environment, imagine that but tuned for building microservices; we are sure you are going to love it! Third, Lagom comes with batteries included for deploying in production: going from development to production could not be easier. In this session, you will get an introduction to the Lightbend Lagom framework. There will be code and live demos to show you in practice how it works and what you can do with it, making you fully equipped to build your next microservices with Lightbend Lagom!

Season 7 Episode 1 - Tools for Data Scientistsaspyker
Metaflow (Ville Tuulos)
Data scientists at Netflix are expected to develop and operate large machine learning workflows autonomously. However, we do not expect that all our scientists are deeply experienced with distributed systems and data engineering. Metaflow was created to make it delightfully easy to build and operate ML workflows in the cloud using idiomatic Python and off-the-shelf ML libraries, covering the whole lifecycle of an ML project from prototype to production.
Polynote (Jeremy Smith)
Polynote is a new notebook tool we created from scratch to address some of the pain points we've run into while using Scala in machine-learning notebooks at Netflix. It provides essential code editing features other tools lack like interactive auto-completes, support for mixing multiple languages and sharing data between them within a single notebook, and encourages reproducible notebooks with its immutable data model.
Papermill (Matthew Seal)
Nteract is an open source organization under which there are several libraries and applications that Netflix and many other companies and individuals contribute to. One of these libraries is Papermill, a library used to programmatically parameterize and execute Jupyter Notebooks. Papermill provides a CLI and Python interface that we'll explore during the session to see how it can be used and what value it adds. Using this pattern we'll also briefly talk about how we've integrated papermill at Netflix and how it interfaces with other Jupyter and nteract services.
Designing Stateful Apps for Cloud and KubernetesEvan Chan
Almost all applications have some kind of state. Some data processing apps and databases have huge amounts of state. How do we navigate a cloud-based world of containers where stateless and functions-as-a-service is all the rage? As a long-time architect, designer, and developer of very stateful apps (databases and data processing apps), I’d like to take you on a journey through the modern cloud world and Kubernetes, offering helpful design patterns, considerations, tips, and where things are going. How is Kubernetes shaking up stateful app design?
S3, Cassandra or Outer Space? Dumping Time Series Data using Spark - Demi Be...Codemotion
Vast volume of our processed data is Time Series data and once you start working with distributed systems, you start tackling many scale and performance problems: How to handle missing data?Should I handle both serving and backed process or separating them out? Best Performance for Money? In the talk we will tell the tale of all of the transformations we’ve made to our data model@Windward, some of the problems we’ve handled, review the multiple data persistency layers like: S3, MongoDB, Apache Cassandra, MySQL. And I’ll try my best NOT to answer the question “Which one of them is the Best?"
In this session we will start to see What is Serverless and what it means to you ? Knowing that we will continue our journey to quickly deploy a serverless platform Apache OpenWhisk on Kubernetes. Having platform ready we will then demystify what should be your Java Programming model in the serverless world???. Is this enough for me to build my serverless applications, the answer is !!!NO!!! , then what else is required, “TOOLS” , in the last part of this session we will stock check our inventory of tools that can make the serverless journey quick, easy and productive.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.
