Introduction to Node.js: perspectives from a Drupal devmcantelon
I gave a talk on November 25, 2010, on Node.js, and related technologies, to the Vancouver Drupal Users Group. The talk ran through why node.js is useful for realtime web apps, how to get it and Express up and running, and how to access data from Drupal and MongoDB.
These are the slides from the sold out Philly Tech Week Introduction to NodeJS workshop run by Ross Kukulinski, a product manager at NodeSource.
In this tutorial, we will provide a brief overview of NodeJS, including its strengths and weaknesses, best practices, and package management. After the introduction, attendees will have the remainder of the tutorial to learn NodeJS through hands-on NodeSchool.io exercises with assistance from a team of mentors.
NodeSchool.io is a series of choose-your-own-adventure style workshops that teach people how to use NodeJS, NPM, and other related tools by writing code to solve realistic problems. NodeSchool is entirely community driven and is 100% open source, which means you can take the exercises home and continue to learn!
Node.js tutorial for beginner will tell the audience about the basic of Node.js which is often called NODE. It include topics such as node.js history, node.js tutorial audience, node.js advantages etc
Node.js and How JavaScript is Changing Server Programming Tom Croucher
Node.js is a highly concurrent JavaScript server written on top of the V8 JavaScript runtime. This is awesome for a number of reasons. Firstly Node.js has re-architected some of the core module of V8 to create a server implementation that is non-blocking (similar to other event driven frameworks like Ruby’s Event Machine or Python’s Twisted). Event driven architectures are a natural fit for JavaScript developers because it’s already how the browser works. By using an event driven framework Node is not only intuitive to use but also highly scalable. Tests have shown Node instances running tens of thousands of simultaneous users.
This session will explore the architectural basics of Node.js and how it’s different from blocking server implementations such as PHP, Rail or Java Servlets. We’ll explore some basic examples of creating a simple server, dealing with HTTP requests, etc.
The bigger question is once we have this awesome programming environment, what do we do with it? Node already has a really vibrant collection of modules which provide a range of functionality. Demystifying what’s available is pretty important to actually getting stuff done with Node. Since Node itself is very low level, lot’s of things people expect in web servers aren’t automatically there (for example, request routing). In order to help ease people into using Node this session will look at a range of the best modules for Node.js.

Mapping Flatland: Using MongoDB for an MMO Crossword Game (GDC Online 2011)Grant Goodale
WordSquared is a massively multiplayer online scrabble crossword that uses MongoDB to store location data. Players place tiles in realtime, and compete to build the longest chain of words and earn points. WordSquared leverages MongoDB's built-in geospatial indexing, storing an x and y coordinate with each tile and using bounding box queries to
display a view of the board.
This presentation covers the architecture of the game, with a specific focus on the use of MongoDB, storing and querying location data, and learning how to structure and even shard geo data through the unlikely use
case of an infinitely large board game.
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.

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.

GraphRAG is All You need? LLM & Knowledge GraphGuy Korland
Guy Korland, CEO and Co-founder of FalkorDB, will review two articles on the integration of language models with knowledge graphs.
1. Unifying Large Language Models and Knowledge Graphs: A Roadmap.
https://arxiv.org/abs/2306.08302
2. Microsoft Research's GraphRAG paper and a review paper on various uses of knowledge graphs:
https://www.microsoft.com/en-us/research/blog/graphrag-unlocking-llm-discovery-on-narrative-private-data/
2. What is ?
“Evented I/O for V8 Javascript” – http://nodejs.org
Application engine for “scalable network applications”
Really freaking fast:
One process, zero* threads
(Almost) no blocking
* actually, there is a thread pool. We’ll get to that.
3. What is ?
High concurrency with low overhead
No thread swapping or context switching
Applications must be designed from the ground up to
not block on I/O, CPU-intensive work, etc.
4. What Node.js Isn’t
A full-stack web framework (a la Ruby on Rails)
But! you can get there:
ExpressJS: (http://expressjs.com/) (Web framework
with MongoDB support built in - similar to Sinatra)
http://github.com/senchalabs/connect (Rack-like
middleware for Node and Express)
haml.js: http://github.com/visionmedia/haml.js (Pure
js implementation of HAML)
5. What Node.js Isn’t (cont.)
Great at sending large static files concurrently. (use
nginx.)
Buffer implementation in recent versions improves
this dramatically: http://nodejs.org/jsconf2010.pdf
Completely non-blocking.
CPU-intensive stuff will still block you (do it in a
worker process).
Some system calls (executed in a thread pool)
7. &
Great together! Both:
speak Javascript
understand JSON documents
are freaking fast.
So, what should you build?
8. &
You can build: Standard n-tier web applications
Great way to learn mongoDB and Node
Go build a blog engine! (Everyone does.)
Lots of libraries to help you get started: ExpressJS,
Connect, etc.
9. &
You should build:
Applications requiring high throughput and
concurrency
Applications with real-time needs
Applications with long-polling connections
Real-time multiuser chat
Web or log analytics (e.g. Hummingbird)
10. Getting Started
Grab the following:
mongoDB: http://www.mongodb.org/downloads
Node.js: http://nodejs.org/#download
npm, a package manager for Node:
curl http://npmjs.org/install.sh | sh
11. Getting Started
Use npm to install a mongoDB driver for Node:
npm install mongodb
Tons of other fun stuff as well - full package list at
http://npm.mape.me/
20. Other Fun Stuff:
http://wiki.github.com/ry/node/modules (Need
extensions? We got 'em.)
Routers, file servers, frameworks, crypto...
http://socket.io/: Cross-platform WebSockets
Supports HTML5 websockets
Falls back to Flash / AJAX in less capable browsers
How many people have used Node.js? In production?
Start with V8: http://code.google.com/p/v8/
Chrome’s javascript engine (Fast, aggressively developed)
Add Evented I/O, system calls, HTTP libraries
First created by Ryan Dahl @ Joyent
“Scalable network applications”: tens of thousands of simultaneous connections on a single box
High concurrency apps are likely to encounter the C10k problem:
http://www.kegel.com/c10k.html
Overhead per connection: An order of magnitude smaller than most libraries’ thread stack allocations.
Builds on the approaches used by libasync, twisted, evenmachine, etc.
Use kernel level event notification (kqueue, epoll, etc.) to notify when files, network connections etc. are ready to be used. App can do other work rather than blocking.
Node shares more with Twisted than Rails
nginx is amazing at handling static content.
Buffers are the suggested way for handling binary data, large data, etc.
The Buffer API is detailed here: http://nodejs.org/api.html#buffers-2
Mongo’s shell is javascript, can execute javascript in process
You can actually write your entire application in javascript - front end and back!
In fact, there are several blog engines already. Try Wheat.
Of course, building your UI on top of Node.js isn’t a bad idea if the rest of your app fits as well - no need to run a Rails app next to your Node app just for a GUI. (cf. Hummingbird).
The current js driver supports master and slave connections, atomic operations, map/reduce...
Chained execution of callbacks is how most every Node program will work.
Recent builds of Node support udp sockets.
Mongo’s great at storing semi-structured data quickly
As much fun as quadruply-nested callbacks are.
As much fun as quadruply-nested callbacks are.
Hydrating documents loaded from the db converts them into instances of our models.
Looks almost like Rails...
