This document discusses module bundling tools for JavaScript applications. It introduces the problems of growing code complexity and need for optimized delivery of code. It then summarizes two popular module bundling tools: Webpack and jspm. Webpack supports CommonJS, AMD and ES6 module syntax and uses loaders and plugins to bundle assets. jspm uses the SystemJS module loader and bundles modules for production, while loading them asynchronously for development. Both tools aim to address the challenges of modular code management and optimized delivery.

There are many build tools available to JavaScript developers, but Webpack is quickly emerging as the leader of the pack. To better understand its use cases and where it excels above the rest, Jake Peyser will walk you through how to use it as a task runner and module bundler, as well as a few other handy tips. Come learn why Webpack is the most popular build tool with React developers.
Webpack is just a module bundler, they said. What they didn't say is why we need it, and what was the motivation that made us achieve what Webpack have been doing for us. In this talk we will navigate through the years of front-end development, ranging from 2003 to nowadays to understand this, and in the end, we will walk thought a complete Webpack project to understand how it works.

Node.js and server side JavaScript are powerful technologies, although they do not stand on their own in enterprise environments, where Java has been the reigning force for many years. Bridging Node.js and Java provides a much sought after migration path for many Java developers who are moving to their systems to JavaScript. Last year we opened sourced J2V8, a rich set of bindings for Google's V8 JavaScript runtime, this year we built upon that work to bring Node.js to JVM.
In this talk we will introduce Node4J, our NodeJS bindings for the JVM and demonstrate it in action. We will explore the performance characteristics and highlight tools that will help you develop, debug and deploy NodeJS applications running directly on the JVM. We will explain how we integrated NodeJS, with Java through a JNI bridge, and demonstrate how you can use this technology to bridge the gap between JavaScript and Java.

Going Above JSF 2.0 with RichFaces and SeamLincoln III
In this session, Jay Balunas and Lincoln Baxter, III will provide in-depth coverage of several of the new JSF 2.0 features, focusing on the sufficiency and shortcomings of each feature. They will also review how RichFaces 4 and Seam 3 are enhancing JSF to solve these shortcomings by prototyping functionality for the future of JSF.
The JSF 2.0 specification (JSR-314) addresses a substantial number of long standing pain points that JSF users have come to accept as a hard-knock life. At last, JSF is a true contender amongst Web frameworks. However, JSF 2.0 is not the end of the story as, thankfully, the expert group has once again left the door open for projects like RichFaces and Seam to extend, prototype, and improve the specification. RichFaces leads the industry with Ajax support for JSF1.2, played a significant role in the development of JSF 2.0, and continues to lead and prototype the future of the JSF standard for the RIA ecosystem; Seam provides leading support for the Conversation Scope, Flash Scope, Internationalized Messages, Managed Transactions, and Conversion/Validation - including cross-field validation.
While this session effectively provides an overview of the JSF 2.0 specification, the underlying goal of this session is to serve as an outreach to identify outstanding recommendations for making the framework more pleasant and productive to use. In addition, this session will illustrate how members of the JSF community can get a sneak peek into the future by using the RichFaces and/or Seam projects. Whether you are a new JSF/RichFaces/Seam user who wants to find out more about the latest developments in the specification, or an old hat with an issue or two on your mind, this session has something to offer you . Attendees are encouraged to bring their own concerns and suggestions to this session.

# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

Multi-cluster Kubernetes Networking- Patterns, Projects and GuidelinesSanjeev Rampal
Talk presented at Kubernetes Community Day, New York, May 2024.
Technical summary of Multi-Cluster Kubernetes Networking architectures with focus on 4 key topics.
1) Key patterns for Multi-cluster architectures
2) Architectural comparison of several OSS/ CNCF projects to address these patterns
3) Evolution trends for the APIs of these projects
4) Some design recommendations & guidelines for adopting/ deploying these solutions.
4. The Problem
• Web sites are turning into Web apps
• Code complexity grows as the site gets bigger
• Developers prefer discrete JS files/modules
• Deployment requires optimized code in just one
or a few HTTP calls
• No standardized import functionality (until now)
8. True App Modularization
• Code is split up into different modules.
• Dependency graph
• The loading order is irrelevant.
• Code gets executed if all dependencies are
loaded.
• Dependencies can be mocked.
9. App delivery
• Requests are expensive.
• Deliver as few files as possible.
• Deliver the «above the fold» data first.
• Deliver only code that is needed by the client.
11. Assets Versioning
• Adds its hash value to the file name
• Allows for setting long expiration headers
• Requires the HTML to update as well.
• Supported by most popular backends
/static/dist/main-ebf5ec7176585199eb0a.js
28. jspm / SystemJS
• Package manager (jspm) and module loader
(SystemJS)
• For development: load modules synchronously
• For production: create a bundle
• Support for SPDY (via its own CDN) and possibly
HTTP2
29. jspm / SystemJS
• In active development
• Uses npm and Github as registries
• A CSS loading plugin is available
• Development != Production environment
This is an actual portrait of me, drawn by the very talented Tika.
From Require.js
Real Website example: 45 Scripts
Server side Bundler
No explicit dependencies in the scripts. Bundler does not value dependencies.
Order of the scripts is important
Global Object, provides a namespace.
Everything goes into that object.
Closure
Does not pollute global namespace.
Dependency on global objects.
Unit testing is difficult
Modules define their dependencies.
Module loaders build a dependency graph and package the modules accordingly.
Dependency Injection.
Modularization competes with delivery over HTTP (1).
Think about how you package your assets.
The app should deliver several static files:
A common-chunks.js file with all the code that is shared over multiple pages. So it can be cached by the browser.
A Js file with code specific for the current app.
Code for sections wich are rarely used or needs a big library should be split out into a separate module which is loaded asynchronously on-demand.
e.g. Webpack exports a JSON with the asset targets and file names. Django has a library called django-webpack-loader that reads that JSON and adds the data into the HTML template. It also waits for Webpack to complete building if necessary.
CommonJS: Introduced with Node.js. Designed for synchronous loading. (Browserify)
Problem: It doesn’t work in the browser.
Asynchronous Module Definition (AMD): Designed for asynchronous loading.
Runs a callback when ready. A bit like $(function(){});

Compared to Browserify it can split the code into multiple modules.
Component structure: CSS and Image are also part of a component and can therefore be included.
CSS load order is not guaranteed if CSS is embedded in the Javascript files.
You can extract the CSS into its own file.
The configuration is a Javascript object.
Because it is a CommonJS module, configurations can be extended by other modules.
E.g. a production config can just import the default configuration and overwrite the necessary properties.
Assets are loaded using a loader. The test property is a regex that is applied to all the files in a directory.
Loaders can be chained and passed attributes.
The first loader tests for js and jsx files and uses babel to parse ES6 code.
SCSS and LESS loaders can work in the same project. (3rd party library used less).
URL loader copies the files if they are less than 20kB. Otherwise it embeds them. Copied files can be given a hash-name.
Automatically creates separate bundles for parts of the app that are only needed on demand.
Here the FilmApp is a large React application that is only loaded if an element with the ID 'film-gallery' is present in the DOM.
Webpack Dev server stores files in memory.
You have to chose between live reload and source maps.
Web inspector only shows source maps for css if the source file is a CSS file.
Bower can be used, but it is not necessary.
No Gulp required. (Gulp can be used but makes the builds slower.)
NPM is the default package manager (and task runner)
Have a separate config file for production builds.
Replace destination paths, add ugilfyJS
NODE_ENV environment variable is used by React to remove debugging statements.
jspm is a package manager for the SystemJS universal module loader, built on top of the dynamic ES6 module loader
SystemJS is a Polyfill for the System specification
There is no Javascript watch and compiling tasks in development.
jspm Version 0.16.0 was released on 18. August.
jspm Version 0.16.6 was released on 19. September.
7 Releases in one Month.
SystemJS: 6 releases in the last two weeks.
Sass loader plugin is still in alpha stage.
