Engage 2020: Hello are you listening, There is stream for everythingFrank van der Linden
The world is changing in a event driven world
Event driven architecture is not a new technology. IBM MQ is already 25 years old.
The popularity is increasing, because it is a robust, decoupled way to exchange data.
Today there are new popular 'new kids on the block'. Kafka is one of them and gets lots of attention also in the enterprise.
The principle however are still the same, called Pub Sub principle.
HCL will add to the App Dev pack the possibility to consume and produce to a broker/stream.
There are frameworks who helps you to focus on the business logic.
In this session I will explain this principle and show you that is not that difficult to make use of it. Connect your existing code to a service bus or queue, producing and consuming.

This is a presentation for International Lisp Conference 2012 which was held in Kyoto, Japan.
Clack is a web application environment for Common Lisp to make your web applications be portable and reusable by abstracting HTTP into a simple API.
In this paper, I describe what are problems in web development and how Clack solves them.
Infrastructure microservices such as Service Discovery and Routing need mechanisms to manage distributed state. The most common answer for this is the use of a central, consistent key value store such as Consul, Etcd or Zookeeper. These systems use consensus-based algorithms, such as Raft or Paxos, to provide consistency and failure tolerance.
I believe this is a dangerous direction for our industry, and instead we should be focusing on ease of use and reliabiligy. As such, Weave wants its infrastructure microservices to be decentralized, yet easy to install and run; our approach is inspired by the Internet, which is distributed and operates with no consensus. In this talk, I'll explain how we designed our Service Discovery and Address Management using Convergent Replicated Data Types (CRDTs) and Gossip, review the pros and cons of this concept, and how it compares to alternatives.

Devops and Immutable infrastructure - Cloud Expo 2015 NYCJohn Willis
You often hear the two titles of "DevOps" and "Immutable Infrastructure" used independently.
In his session at DevOps Summit, John Willis, Technical Evangelist for Docker, will cover the union between the two topics and why this is important. He will cover an overview of Immutable Infrastructure then show how an Immutable Continuous Delivery pipeline can be applied as a best practice for "DevOps." He will end the session with some interesting case study examples.

Run your Dockerized ASP.NET application on Windows and Linux!Alex Thissen
Presentation for Dutch Docker Day 2015:
Before today the power of ASP.NET web applications was limited to Windows machines. But now ASP.NET 5 has been introduced that limitation is gone. With ASP.Net 5 becoming cross-platform, this opens opportunities for new scenarios on different platforms. But where and how do you deploy it? Wouldn’t it be great to run ASP.NET 5 in a Docker container? With the introduction of Windows 2016 it will be possible to do this and deploy and run your application in a Docker container on both Windows and Linux.
In this innovative talk, Alex and René will give you a quick overview of the endless possibilities of Docker on Windows and Linux in combination with ASP.NET 5

Alvaro Videla, Building a Distributed Data Ingestion System with RabbitMQTanya Denisyuk
In this talk I am going to show how to build a system that can ingest data produced at separate geo located areas (think AWS and it’s many regions) and replicate it to a central cluster where it can be further processed and analysed. I will present an example of how to build a system like this one by using RabbitMQ Federation to replicate data across AWS Regions and RabbitMQ support for many protocols to produce/consume data.
To help with scalability I am going to show an interesting way to implement sharded queues with RabbitMQ by using the Consistent Hash Exchange.
In this presentation Guido Schmutz talks about Apache Kafka, Kafka Core, Kafka Connect, Kafka Streams, Kafka and "Big Data"/"Fast Data Ecosystems, Confluent Data Platform and Kafka in Architecture.

# 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

1.Wireless Communication System_Wireless communication is a broad term that i...JeyaPerumal1
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.
