This document discusses using the Kinect sensor with Node.js. It describes connecting the Kinect to Node.js using the Audio Data API and Socket.IO for real-time data streaming. Code examples are provided for an Express server to handle requests and websockets, and using TCP/IP to receive Kinect sensor data and broadcast it over websockets.

Decentralized Stream Processing over Web-enabled DevicesMasiar Babazadeh
The presentation introduces the Web Liquid Streams (WLS) framework. WLS lets developers create distributed topologies across a pool of heterogeneous devices thanks to the abstraction offered by JavaScript, the lingua franca of the Web. Through a set of use case scenarios we show the feasibility of the approach.
A brief introduction to the world of drones, flying robots and the #nodecopter project. I've presented this work at events such as Research Talks, Wajug, Njugbe, Café Numérique, etc.
If you would like to have this presentation featured at one of your events, don't hesitate to contact me by email.
A presentation given on August 7th 2013 at the Belgian NodeJS user group. Discussing autonomous flights topics for the AR Drone 2.0 controlled via NodeJS (nodecopter.com).
Our favorite language is now powering everything from event-driven servers to robots to Git clients to 3D games. The JavaScript package ecosystem has quickly outpaced past that of most other languages, allowing our vibrant community to showcase their talent. The front-end framework war has been taken to the next level, with heavy-hitters like Ember and Angular ushering in the new generation of long-lived, component-based web apps. The extensible web movement, spearheaded by the newly-reformed W3C Technical Architecture Group, has promised to place JavaScript squarely at the foundation of the web platform. Now, the language improvements of ES6 are slowly but surely making their way into the mainstream— witness the recent interest in using generators for async programming. And all the while, whispers of ES7 features are starting to circulate…
JavaScript has grown up. Now it's time to see how far it can go.
Playing With Fire - An Introduction to Node.jsMike Hagedorn
node.js is an evented server-side Javascript framework powered by the Google V8 Javascript engine. It is a platform ideal for creating highly scalable web applications. It has the same simplicity of frameworks such as Sinatra, but is designed to be more peformant from the ground up. This performance is achieved by making all network I/O non blocking and all file I/O asynchronous. We will go over how that impacts the development experience, and walk through a simple web application. Javascript is foundational to this type of I/O because it is already evented by design. We will also take a brief look a similar evented frameworks such as ruby`s EventMachine.
I gave a talk about an excellent Clojure/ClojureScript rule engine library at Ichigaya Geek Night September 22 2017. https://ichigayageek.connpass.com/event/65356/
Modern web applications have constantly growing requirements and their complexity grows exponentially. Some of the biggest challenges in front of us are state management, testability, flexibility and on top of that we need to develop the application at reasonable level of simplicity in order to ease the recruitment process.
In this presentation I'll introduce a scalable Angular 2 application architecture, which answers the following requirements:
- Testability.
- Predictable state management.
- Scalable communication layer.
- Modular and robust design

Using the Kinect for Fun and Profit by Tam HannaCodemotion
Very few devices offer as fascinating features as the Microsoft Kinect. This seminar teaches you what the Kinect can do and how you can develop for it.
Attendants are recommended to bring a notebook with Visual C# 2010 express edition and the latest Kinect SDK so that they can fully profit from the talk. A sensor will be available for testing own applications.
Firefox OS, HTML5 to the next level - Python Montreal - 2014-05-12Frédéric Harper
If you are like me, your spectrum of interest is large when it comes to technology. You may be a Python developer, but that does not mean you have not any interest in HTML, and it’s a good coincidence as it’s the foundation of my presentation. In this talk, Frédéric Harper will show you how you can use HTML5 with the power of JavaScript to build amazing mobile applications as to brush up what you previously published. Learn about the open web technologies, including WebAPIs, and tools designed to get you started developing HTML apps for Firefox OS, and the web.
HTML5 is all the rage with the cool kids, and although there’s a lot of focus on the new language, there’s plenty for web app developers with new JavaScript APIs both in the HTML5 spec and separated out as their own W3C specifications. This session will take you through demos and code and show off some of the outright crazy bleeding edge demos that are being produced today using the new JavaScript APIs. But it’s not all pie in the sky – plenty is useful today, some even in Internet Explorer!
Anything that can be written in JavaScript, will eventually be written in JavaScript. First client side web apps, then server side programs and now you can control hardware, embedded devices and even flying robots with JavaScript.
We'll look at how you can get started writing JavaScript for Ardunio and Raspberry Pi to read sensors and control servos and build your own JavaScript powered robots.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

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. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
