This document summarizes Jeff McDonald's presentation about advanced features in Catapult, the next generation blockchain platform from NEM. It discusses how Catapult improves on previous blockchain databases like Bitcoin and Ethereum by adding support for plugins, standards, and off-chain contracts to enable new use cases. Examples highlighted include Apostille for notarization, voting protocols, aggregate transactions, multi-layered multisig accounts, and IoT integration. The presentation also promotes NEM's developer tools and SDKs and showcases several community blockchain projects built on NEM.

All these concepts are introduced gradually through a metaphor then simple mental models followed by a first principle thinking level.

Presenter: Sun Sagong
Venue: Tenx (Singapore)
Date: 07Feb2018
A broad market update from 8DC from July 2022. A view on Why Crypto? The case for Bitcoin and Ethereum. DeFi as the first proper use case for crypto. And why now is the time to invest.
Bitcoin is a digital, decentralized, partially anonymous currency, not backed by any government or other legal entity, and not redeemable for gold or other commodity. It relies on peer-to-peer networking and cryptography to maintain its integrity. A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
DevOps and Testing slides at DASA ConnectKari Kakkonen

Finally we had lovely workshop with the participants trying to find out different ways to think about quality and testing in different parts of the DevOps infinity loop.
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.

1. money
2. gas
• Gas powers a virtual machine.
• Contracts exist in the VM.
6. Blockchain Database
NEM really makes the blockchain as a true database solution.
IoT
NEM can be used for all these other use cases by adding support for all these features directly
into the core via plugins or as 2nd layer standards.

Decentralized
(Not efficient but very secure)
Centralized is a read and write database. Blockchain is a write once, read many database.
Blockchain is a cryptographically safe, secure, decentralized and immutable database.
The cryptography shows direct A -> B history, and the decentralization shows that it wasn’t ever tampered with.
Decentralization also helps to make sure that apps can’t be censored and that it is available in all markets all the time.
Centralized databases predate the internet and therefore don’t have security built in to compensate for a post-internet world where hackers can remotely attack.
