In this talk, we talked about NPM. Why is it so powerful and verticals where it is being used apart from Node.js. Also we go through the basic packages and how can we build a simple CLI tool with Node.js and publish it on NPM.
NPM is a package manager for the JavaScript programming language. It is the default package manager for the JavaScript runtime environment Node.js. It consists of a command line client, also called npm, and an online database of public and paid-for private packages, called the npm registry.
NodeJS is an open source, cross platform run time environment for server side and networking application. NodeJS is popular in development because front & back end side both uses JavaScript Code.
webpack is a powerful module bundler and it becomes an essential part of our JavaScript Ecosystem. This ppt comprises an overview on webpack, some of the core concepts of webpack and it's configurations with some working examples.
CRUSH is the powerful, highly configurable algorithm Red Hat Ceph Storage uses to determine how data is stored across the many servers in a cluster. A healthy Red Hat Ceph Storage deployment depends on a properly configured CRUSH map. In this session, we will review the Red Hat Ceph Storage architecture and explain the purpose of CRUSH. Using example CRUSH maps, we will show you what works and what does not, and explain why.

BlueStore: a new, faster storage backend for CephSage Weil
Traditionally Ceph has made use of local file systems like XFS or btrfs to store its data. However, the mismatch between the OSD's requirements and the POSIX interface provided by kernel file systems has a huge performance cost and requires a lot of complexity. BlueStore, an entirely new OSD storage backend, utilizes block devices directly, doubling performance for most workloads. This talk will cover the motivation a new backend, the design and implementation, the improved performance on HDDs, SSDs, and NVMe, and discuss some of the thornier issues we had to overcome when replacing tried and true kernel file systems with entirely new code running in userspace.
In NPM THE GUIDE you will learn how to use npm to install packages and update them. Delve deeper into more command line commands to help speed up workflow and finally use npm in your scripts to utilise npm’s additional features.

Learn to leverage the power of server-side Javascript with this Node.js introductory tutorial. We’ll dive into Node’s architecture and understand the build and dependency management systems involved. Several modules for Node will be demoed, and we’ll learn how to debug Node applications within an IDE. You’ll come away with an understanding of what sets Node apart from traditional Javascript, it’s inherently asynchronous and event-driven architecture, and take a look at some real world applications built on Node.
Strategies for developing and deploying your embedded applications and imagesMender.io
We will delve into multiple strategies you can use for developing and deploying code to embedded devices. We will compare and contrast the following:
– Lightweight package managers: ipkg/opkg
– Desktop package managers: rpm/deb
– Configuration Management Tools
– Smart Package Manager
– Yocto Runtime Package Management
– PXE boot
– OTA updaters: Mender
As with any decision, it is rarely black-and-white and we will cover some of the benefits and the limitations of all the different methods mentioned, to make sure you have the most critical information needed to decide for yourself whether a given strategy would be a good fit for your embedded application development.
This talk will cover how different mechanisms are implemented in the real world and how choosing the right strategy, understanding its benefits and drawbacks, can speed up and improve the whole development process.
In this video we will be covering about express npm, first we will see the overview of npm after that we will see what is npm, after that we will see what is a package, moving ahead we will see the functions of node package manager and then we will see how to install it. All of Node.js's packages and modules are managed through NPM, which also includes the npm command-line client. Along with the installation of Node.js, it is added to the system. NPM is used to install the necessary modules and packages in a Node project. We use a command-line tool to manage Node.js package dependencies, version control, and installation of modules.
NPM( Node Package Manager) is Node.js's built-in package manager by default, and Express js is the framework of Node js, which is fully built-in Javascript. It was created by Isaac Z. Schlueter and was first made available on January 12, 2010.
What is NPM?
Let's take async as an example. NPM is incredibly easy to use; all you need to do is type npm install async to install the desired module in the current directory under /node modules/. You may use need() on them as if they were built-ins once installed in your node modules folder.
The biggest software registry in the world is npm.
There are more than 800,000 code packages in the registry.
To share software, open-source developers utilize npm.
Npm is often used by businesses to control private growth.

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.
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.

2. Introduction to
Agenda
● What is NPM?
● Understanding package.json
● Where to find Packages?
● Installing Packages
● Writing your own Packages
● Command Line
● Publishing to NPM
● Questions & Exercises
4. Introduction to
What is NPM?
● A Node Package Manager
● No other Package Manager comes closer
● Is also used by developers who don’t use Node.js at all
● Created by Isaac Z. Schlueter
● Breeze to use
● Recently made into a company, NPM Inc. by Isaac
● Free and Open Source!
5. Introduction to
Understanding package.json
● It is a valid JSON object
● name and version fields are required, the combination
makes a unique identifier for the package
● Some used fields in package.json
○ description
○ keywords
○ homepage
○ bugs
○ license
○ author & contributors
○ main
○ bin
○ dependencies
○ scripts - {start, preinstall}
7. Introduction to
Installing Packages
● npm comes along with node.js
● to install a package run:
○ npm install <package-name>
○ npm install <tarball file>
○ npm install <tarball url>
● install a package globally
○ npm install -g <package-name>
Note: Global installation makes the package available globally irrespective of the directory you installed it from.
8. Introduction to
Writing your own packages
● Install Grunt , the javascript task runner
○ npm install -g grunt-cli
● Run command :
○ grunt-init node
● Answer few questions and you are ready with a nice
package.json file and main .js file for your package.
9. Introduction to
Writing your own packages
The generated folder structure should look something like this:
Write the code in the .js file created, you can also create many more files as
per your need.
10. Introduction to
Writing your own packages
Some guidelines to keep in mind when writing new
packages:
● Don’t reinvent the wheel
● Try to contribute to other packages whenever possible
● If you are writing a utility package, then multiple exports should be used
● If your package needs to maintain a state then its good to export a
constructor
● Most Important thing, KEEP IT COOL!
11. Introduction to
Command Line
To be able to use your package through command line, you need to specify
‘bin’ in package.json as follows:
"bin": {
"nodeart": "lib/nodeArt.js"
}
Also add this #! /usr/bin/env node at the top of “lib/nodeArt.js” file. This tells how the file should be
executed.
As above, ‘nodeart’ will be the command available to you when you install
the package on your machine.
12. Introduction to
Command Line
You can receive the arguments passed from command line in process.argv
array. First two values in the array are pre-defined :
[ 'node', '/opt/node-v0.10.5-linux-x64/bin/nodeArt']
The actual arguments being passed will be available at indexes greater than
1. So if you run nodeart ‘suroor wijdan’, the process.argv array will be:
[ 'node', '/opt/node-v0.10.5-linux-x64/bin/nodeArt', ‘suroor wijdan’]
13. Introduction to
Command Line
So its better to slice the array and store the arguments in another variable:
var argumentsPassed = process.argv.slice(2);
14. Introduction to
Publishing to NPM
To publish on NPM, you just need to have an account on it. To make an
account run the following command:
Once you have the account ready, just run the below command from project
root to publish your module:
And thats all, everything else will be taken care of by NPM registry.
npm adduser //will ask for username, email and password
npm publish
