Still running on Java 8? Tempted by new versions of Java, but afraid too? This material contains some information on what to expect, and what kind of lessons were learned taking multitude of Java 8 projects to Java 9, 10, and 11.
Node.js Development with Apache NetBeansRyan Cuprak
This session covers the basics of developing Node.js applications with NetBeans. NetBeans includes fully integrated support for both JavaScript and Node.js. You’ll get a tour of the features and learn how NetBeans can accelerate your projects. The presentation looks at basic code editing capabilities provided by the IDE, tool integration (npm/Grunt/Bower/Webpack), frameworks such as Express, and debugging capabilities. You’ll see why NetBeans is the best free JavaScript/Node.js IDE.
Jakarta EE is now over 20 years old and despite its age, it is as relevant today as it was back in 1999. It is one of the few open standards for developing enterprise applications with multiple independent vendor implementations. Its APIs are central to developing Java based cloud solutions. It is as relevant today as it was back in 1999. This presentation will provide context to Jakarta EE and why businesses choose to use it.
In this Presentation, we have provided step by step Installation guide and error free solution for developers which helps in time efficient and user friendly installation of theme in Liferay 7.
Presentation Abstract:
Are your applications running on Java 8? Thinking about switching your application to run on Java 11 and wondering about where to start? Come to this session to learn about the most impactful changes that went into Java 11 and what you will need to do to move your application to run on Java 11. Topics will include the removal of APIs (such as Java EE packages) and behavior changes resulting from moving an application from running on Java 8 to running on Java 11. We will also go over tools to use that will help you identify potential issues within your application and how to resolve them.
Java 9 ships in July, are you ready for Java 9 modules? Java 9 modules (aka Project Jigsaw) is the biggest fundamental change to the Java runtime. Code that use Oracle/Sun private APIs will break. This session will cover the basics of Java 9 modules and also the current state of tooling. The ramifications to existing and legacy applications will be covered along with the steps you’ll need to take to harness the power of modules and write more maintainable systems.

Faster java ee builds with gradle [con4921]Ryan Cuprak
JavaOne 2016
It is time to move your Java EE builds over to Gradle! Gradle continues to gain momentum across the industry. In fact, Google is now pushing Gradle for Android development. Gradle draws on lessons learned from both Ant and Maven and is the next evolutionary step in Java build tools. This session covers the basics of switching existing Java EE projects (that use Maven) over to Gradle and the benefits you will reap, such as incremental compiling, custom distributions, and task parallelization. You’ll see demos of all the goodies you’ve come to expect, such as integration testing and leveraging of Docker. Switching is easier than you think, and no refactoring is required.
The new GraalVM from Oracle supports multiple language including JavaScript, Python, Ruby, R, C++ as well as Java and other JVM languages. This opens up interesting possibilities for polygot enterprise applications. Now you can use a Node library in a Java application or call an R statistical function from an EJB. Previously, this type of integration was extremely challenging. This session will provide recipes to get up and running along with best practices and some cool demos.

Searching The Cloud - The eclipseRT UmbrellaMarkus Knauer
The emerging Cloud infrastructures offer new ways to develop dynamic services. Eclipse can contribute to these new services today by combining results from various projects. This talk will demonstrate how to set up a simple search application in the Cloud with the help of the following eclipseRT and Eclipse Technology projects:
* g-Eclipse will be used to manage and configure the virtual Cloud resources based on its general Cloud model.
* p2 will be used to deploy the search application.
* SMILA (SeMantic Information Logistics Architecture) is an extensible framework for building search applications for data like office documents, emails, images, audio & video files, blogs etc. One of the features of SMILA is the parallelization of processes/workflows, so the natural deployment environment of SMILA is similar to the distributed environment of the Cloud.
* RAP will be used to create a simple search-UI for the application.
This talk demonstrates existing goodies from Eclipse projects which can help to build Cloud applications independent from underlying infrastructures. It will show the potential power of Eclipse technology on the Cloud.

Slides from my presentation about Shopzilla's concurrency strategies to the Pasadena Java User's Group on April 26, 2010. This is essentially the same material as covered by my colleague Rodney Barlow in an earlier presentation http://www.slideshare.net/rodneypbarlow/shopzilla-on-concurrency, with a few minor tweaks.
Zepto and the rise of the JavaScript Micro-FrameworksThomas Fuchs
Here are my slides from JSConf 2011 in Portland, Oregon. I was talking about Zepto, my micro-framework, WebKit-only (works on Firefox too, though) clone of the jQuery API, and why I think that Micro-Frameworks and Micro-Libraries are better suited for the mobile Web than traditional, monolithic libraries, like script.aculo.us, Prototype or jQuery. (A video of the talk is forthcoming and will be announced on my blog, http://mir.aculo.us).
Abstract
Concurrency is everywhere. Prior to Java 5, concurrency was difficult
and error prone. Since Java 5, it's far more prevalent in our
application code, and through time it's been lurking in open-source
frameworks and containers. Concurrency is also a fundamental part of
Shopzilla's web-site and services ecosystem.
Introduction
Rod Barlow from Shopzilla will explore a brief history of concurrency, and the key
concurrency features and techniques provided by the Java API since
Java 5. Topics covered include Immutability, Atomic References, Blocking
Queues, Locks and Deadlocks. Also covered is Concurrency in
Frameworks, and Shopzilla's Website Concurrency Framework, including
Thread Pools, Executors and Futures.

# 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
2. Intro
Scalable application platform
Real-time system (web applications, game and ...)
Similar to Node.js but not a clone!
Some characteristics like Erlang
Started by Tim Fox (RabbitMQ , HornetQ , Red Hat
Middlewares) in 2011
Sponsored by VMWare (SpringSource) and Red Hat!
Manged by Eclipse Foundation
3. Requirements
JDK 7 or later (Oracle distribution or OpenJDK)
server.js
$ vertx run server.js -instance 10
6. Features
Polyglot
Asynchronous programming model (Non blocking
I/O and event-driven)
Actor-like concurrency
Distributed Event Bus (spans the client and server
side)
Embedded as a library
Module system
9. Polyglot
New JDK 7 Feature (better support for
Dynamically Typed Languages in the JVM)
e.g. invokedynamic bytecode instruction
Support for a New Language as module!
12. Distributed Event Bus
Communication mechanism between
applications components (Clustered)
Spans the client and server side
Use same API in the browser
Pub-Sub, Request/Response
13.
14. Actor-like concurrency
No more synchronized, volatile or explicit
locking
Write all your code as single threaded
Components communicate with each other
over the event bus by exchanging messages.
Number of threads to be equal to the number
of available cores on the machine.
15. Concurrency Model
(Thread model)
Hybrid threading model
Event Loops = number of threads to the available
cores on the server
Multi-reactor pattern (more than one event loop)
The Golden Rule - Don't block the event loop!
Worker Verticles can block - never executed
concurrent (JDBC , …)
Shared map (immutable, distributed)
16. Verticle
Verticle run insdide a vert.x instance
verticle instance is never executed by more
than one thread concurrently (single threaded).
verticle instances communicate with each
other over the event bus by exchanging
messages.
verticle instances correspond to actors. (more
coarse grained than actors)
20. Module System
Public module registry
Auto-redeploy of Modules
JSON configuration
New non-core features done as modules
Runnable modules vs. includable modules
Even new language support is done via
modules!
21. Vert.x API
Container API

UDP
HTTP/HTTPS servers and clients
WebSockets servers and clients
The distributed event bus
Periodic and one-off timers
Buffers
Flow control
File-system access
Shared map and sets

22. How Vert.x scale
Many instance of one verticle
Clustering (auto-magic, configurable)
Eventbus spans through all machine in cluster and browser
Use all available core
Hybrid thread model
Automatic failover (-ha and "bare" Vert.x instances)
HA groups (-hagroup)
Quora (network partitions)(-quorum)
Automatic load-balancing for TCP and HTTP ( available cores)
25. Usage
