Who remembers the days were you had to manually setup a physical server somewhere in a 19 inch rack? Nowadays those physical racks have been replaced by virtual machines provided by Google, Microsoft and Amazon. But some people are still provisioning them manually. The more mature organizations will script most of the provisioning using the native CLI or HTTP API provided by the specific cloud platform, but quite often those are maintained separately from the code of the system that is being deployed. Terraform by Hashicorp is another attempt to support infrastructure-as-code by using a declarative syntex to define the desired infrastructure. But then again, Yaml isn't really suited for anything but simple single-file configuration settings. Yaml isn't code and doesn't provide real Intellisense, line-by-line debugging and most importantly, refactoring. But what if you could use C# and .NET to provision your infrastructure and treat that code as first-class citizens of your codebase, including all the capabilities that you would expect? Well, let me show you how Pulumi for .NET will allow you to evolve your infrastructure code with the rest of the code base without turning it in a big spaghetti of Yaml files.

Platform engineering 101
What does it take to get an application into production? Many processes, tools and automation surround that application to deliver it to the customer. As it becomes more common for development teams to autonomously deliver and run their software, the focus of the traditional operational teams shifts towards an as-a-service mindset. But how is such a team positioned within the company? And is Platform Engineering any different from Software Engineering?
In this talk I’ll share my experiences as a platform engineer and explain why I believe that every company should be conscious about why and how to setup this responsibility. I’ll also discuss the biggest challenges surrounding it - and how to tackle them.

== Dokument bitte herunterladen, falls unscharf! Please download slides if blurred! ==
Kubernetes is the de-facto standard when it comes to container orchestration. But why is there is no established, standard and uniform way to spin-up and manage a single or even a whole farm of Kubernetes clusters yet? Instead, a whole bunch of different and mostly incompatible ways towards Kubernetes exist today. Each with its own pros and cons in regards to ease of use, flexibility and many other requirements. In this session we will have a closer look at the different available options to create, manage and operate Kubernetes clusters at scale.

In this session, we’ll look at the AWS services that customers are using to build and deploy Microsoft-based solutions that use technologies like Windows, .NET, SQL Server, and PowerShell. We’ll start by showing you how to build a Windows-based CI/CD pipeline on AWS using AWS CodeDeploy, AWS CodePipeline, AWS CloudFormation, and PowerShell using an AWS Quick Start. We’ll also cover best practices for how you can create templates that let you automatically deploy ready-to-use Windows products by leveraging services and tools like AWS CloudFormation, PowerShell, and Git. Woot, an online retailer for electronics, will share how it moved from using a complex mix of custom PowerShell code for its DevOps processes to using services like Amazon EC2 Simple Systems Manager (SSM), AWS CodeDeploy, and AWS Directory Service. This migration eliminated the need for complex PowerShell scripts and reduced the operational complexity of performing operational tasks like renaming servers, joining domains, and securely handling keys.
Harnessing the power of aws using dot net core
In the past AWS and C# seemed to belong to two different eco-systems. One was a leading cloud platform while the other a widely used, powerful programming platform.
Does it mean that a developer that needs to provide a solution in the cloud must choose between the two? Not anymore.
In this talk, I will show how to write C# code that runs in a dockerized container in the cloud or as an AWS Lambda and harness, the popular AWS services.

Learning Objectives:
- Learn how you can use the practices of continuous integration and delivery for operationalizing data science and machine learning applications
- Learn how you can use AWS CodePipeline, AWS CloudFormation and Amazon EC2 Container Service along with MXNet to build and deploy deep learning applications
Deep learning (DL) is a computer science field derived from the Artificial Intelligence discipline. DL systems are usually developed by data scientists, who are good at mathematics and computer science. But to deploy and operationalize these models for broader use, you need the DevOps mindset and tools. In this tech talk, we’ll show you how to connect the workflow between the data scientists and DevOps.
We’ll explore basic continuous integration and delivery concepts and how they can be applied to deep learning models. Using a number of AWS services, we will showcase how you can take the output of a deep learning model and deploy it to perform predictions in real time with low latency and high availability. In particular, we will showcase the ease of deploying DL predict functions using Apache MXNet (a deep learning library), Amazon ECS, Amazon S3, and Amazon ECR, Amazon developer tools, and AWS CloudFormation.

Getting a grip on your code dependencies (2023-10)
I'm sure every developer wants to be able to change code with confidence and without fear. Readable and self-explanatory code is one aspect of that. Too much coupling is another major source of problems that prevent you from changing one part of the system without causing side-effects. In this talk, I'd like you to show you common sources of unnecessary coupling and offer you options to help prevent and/or break those. I'll talk about how principles like Don't Repeat Yourself and Dependency Injection can be a double-edge sword, how to detect too unnecessary dependencies and how to use the Dependency Inversion Principle to unravel some of those. And yes, I will also talk about controlling dependencies on the package level.
Challenge
1. How to prevent too much coupling?
2. We are tought to decrease coupling and increase cohesion
3. How do you increase cohesion? By applying DRY!
4. But DRY creates more coupling
5. And too much decoupling results in a forest of abstractions
6. The solution is… find a balance (or "it depends")
On the architecture level
1. Use architecture style that embraces DIP (e.g. Onion, Hexagon, Clean Architecture)
2. Organize your code along functional boundaries -> this will make it easier to break off that boundary for rebuilding/strangler/microservices.
3. Apply DRY within those boundaries only, but allow shared services for complicated capabilities
4. Align your test scope with those internal boundaries…
On the package level
• Classes and interfaces that are almost always used together should be packaged together. Those that don’t meet that criteria don’t have a place in that package
• Packages should not require changes (and thus a new release) for unrelated changes.
• There must be no cycles in the dependency structure
• A package should only depend upon packages that are more stable than it is or abstract packages
On the code level
• Avoid technical folders and organize them by functionalities or capabilities
• Things in adjacent folders usually mean they are separate boundaries
• Use the Tell, Don't Ask principle
• Use the Law of Demeter to detect unnecessary coupling
• Encapsulate primitive types and collections in specific types
• Dependency injection is great, but try to avoid a global container
• It's fine to inject concrete classes inside boundaries
Strategy for legacy code
1. Ensure you have a safety net using characterisation tests
2. Find existing seams and decouple them better
a. Identify modules or functional slices
b. Identify groups of classes that are supposed to be used together and are designed to be reusable
c. Identify interfaces or abstractions in DI registration code and see if they are truly designed for reusability
d. Assume that code in adjacent folders is supposed to be independent
e. Move code from different technical folders that belong together in their own (functionally named) folderPublic
3. Use that to define (and visualize) the target architecture
Tools and practices to help you deal with legacy code
We all love to build greenfield projects, but the reality is that in most jobs you have to deal with a lot of legacy code. This doesn't mean the code is bad. It just means that choices were made that were the right ones at that time, or that the developers were not entire up-to-date with modern development practices. And that's exactly what this talk is about. I enjoy taking such a codebase and gradually introduce architectural seems, add a proper build pipeline, introduce temporary tests and then gradually refactor the codebase to combine more maintainable, testable and reliable. So in this talk, I'd like to unfold my extensive toolbox of practices, principles, tools and mindset to help you improve your legacy code without jeopardizing your business.
Understand production environment
See which vinaries are running in production and what config files are used
Verify the code and the production release are in sync, e.g. DotPeek
Analyze logs to understand what features are used
Try to get it to run on a local environment
Understand code
Generate project diagrams and class hierarchies
Find origin calls and destination of a parameter using Rider
Use navigation options to find inheritors, usages, etc.
Use the namespaces and project names to understand the relation
Have Rider's AI Assistant or ChatGPT explain the code
Track all documentation in a single place
Build C4 diagrams
Find dead code
Reduce the scope of types and members to internal to find more dead code
Detect code inefficiencies and dead code using Rider
Remove commented out code
Build a safety net
If therea are tests, add code coverage reporting using Coverlet and use that to find dark spots
(HTTP API) Characteristics tests using FluentAssertions, Bogus, xUnit. Use AI to generate them. It's fine, you'll delete them later on
Use test containers for .net t lo include the databse
Build a couple of end to end UI tests e.g. using Cypress, Playwright, efc
Improve deployability
Add scripts or builds steps to run the code locally, Nuke build pipeline to get consistency
Adopt a version strategy and name branches accordingly
Adopt automatic versioning using GitVersion
Adopt logging and exception strategy, e.g. Serilog
Pulumi to automate PR deployments
Improve code
Treat all warnings as errors and fix thhem
Editorconfig / eslint so auto-format works
Configure a personal Rider/R# clean-up profile to auto-format file, project and solution

I'll talk about how principles like Don't Repeat Yourself and Dependency Injection can be a double-edge sword, how to detect too unnecessary dependencies and how to use the Dependency Inversion Principle to unravel some of those. And yes, I will also talk about controlling dependencies on the package level.
My Laws of Test Driven Development (2023)
About 15 years ago, I got inspired by a series of posts on Test Driven Development written by the Jeremy D. Miller. Now, with many years of great and not-so-great experiences practicing Test Driven Development, I thought it is the time to capture my own “laws”. The term "law" is obviously an exaggeration and "principles or heuristics" cover my intend much better. Either way, I want to talk about the scope of testing, using the observable behavior, naming conventions, state-based vs interaction-based testing, the impact of DRY, patterns to build useful test objects and some of the libraries and tools I use. In short, everything I try to follow every day I write, review or maintain code.
Design patterns for Event Sourcing in .NET
Event Sourcing is becoming more mainstream these days, and a lot of conferences have demonstrated the pros and cons of this architecture style from multiple angles. I've done a few of these and publishes a lot of articles on best practices and solutions to common problems. But what nobody did was to show you how to build an event sourced systems in the .NET ecosystem. There are a lot of open-source projects that you can use, so you'll need to find a right mix and your own code to that. So let me show you how I would implement this in .NET with almost 10 years of Event Sourcing experience behind my belt.
What is the right unit in unit testing (UpdateConf 2022)
Whether you're just writing your first unit test or have been practicing Test Driven Development for many years, I'm sure your biggest challenge is to find the right scope for testing. Unfortunately a lot of books and guidance seem to imply that every class or type should be tested separately. Well, I can tell you from 15 years of unit testing experience that that's the best way to shoot yourself in the foot.
In this session, I'm going to show you some concrete examples and why I chose a certain boundary for the "unit" in unit testing. I will also share design heuristics I use myself to find those boundaries and why those are not guidelines. I'll also illustrate how principals like DRY and SOLID can be both a blessing and a curse that may lead to the wrong design choices
Slow Event Sourcing (re)projections - Just make them faster!
I don't have to tell anybody how awesome Event Sourcing is as an architecture style. But those that have been using it in production must have experienced the pains of keeping the upgrades fast enough, especially if you use a more traditional relational database like SQL Server. I've once heard somebody say: "If it's slow, make it faster", but rebuilding a big projection is simply a very expensive operations and involves a lot of network traffic between the application and the database servers.
Over the years since we adopted Event Sourcing, we've been experimenting a lot and have implemented various improvements to make those reprojections faster. And we haven't stopped. We're already working on some new ideas lately. So in this session, I'd like to share those techiques, their pros and cons and how we implemented them on a more detailed level.
50 things software teams should not do.pptx
Enough books have been written, articles have been published and Youtube videos have been posted about how you should be behaving as a software developer, Scrum Master or team lead. To be original in this unoriginal world, I started thinking about the things you should NOT be doing. I came up with 50 tools, practices and principles covering topics like dealing with complexity, productivity, architecture, testability, traceability, maintainability, transparency and predictability that I believe hamper you as a professional. That sounds like a lot, but I promise you a fun and entertaining session that I'm sure will trigger a lot of recognition.
What is the right "unit" in unit testing and why it is not a class?
Whether you're just writing your first unit test or have been practicing Test Driven Development for many years, I'm sure your biggest challenge is to find the right scope for testing. Unfortunately a lot of books and guidance seem to imply that every class or type should be tested separately. Well, I can tell you from 15 years of unit testing experience that that's the best way to shoot yourself in the foot.
In this session, I'm going to show you some concrete examples and why I chose a certain boundary for the "unit" in unit testing. I will also share design heuristics I use myself to find those boundaries and why those are not guidelines. I'll also illustrate how principals like DRY and SOLID can be both a blessing and a curse that may lead to the wrong design choices.
A lab around the principles and practices for writing maintainable code
Writing maintainable code is not something that is easy to do. Not only is a pretty subjective, a lot of the techniques like Clean Code, SOLID and such can be misinterpreted resulting in unconstructive dogma. I've made it my career's goal to find a good balance between all those different patterns, principles, practices and guidelines.
In this talk, I'd like to share my own ideas on what it takes to write maintainable code. I'll talk about architecture, class design, automated testing and any consequences on your development process. If you care about your code, be there with me.
How to Practice TDD Without Shooting Yourself in the Foot
It’s 2021, so practices like Test Driven Development (TDD) have long found their way into organizations. However, the practices and principles to keep those unit tests maintainable haven’t really changed. Still, Dennis regularly talks to developers that somehow ended up with an incomprehensible unmaintainable set of unit tests that they once believed in, but are now holding them back. So in this session Dennis likes to provide a refresh of those fundamental ideas and talk about why you should practice TDD, revealing intentions, naming conventions, state versus interaction based testing, and how to stay out of the debugger hell with proper mocking and assertion frameworks.
Decomposing the Monolith using modern-day .NET and a touch of microservices
If I have to name a single biggest hype in software architecture land then it would be "microservice". They are supposed to be small and focused, can be deployed independently, can work with any technology and will solve all your monolithical problems. But we all know that silver bullets don't exist, plus technology should never be a goal, but merely a means to an end. Nonetheless, following the path towards real microservices is a great strategy for decomposing a monolith without the deployment complexity of the first. So how do you do that? What technologies does the .NET realm offer for us? In this talk, I'll show you some of the pros and cons of micro-services and its ingredients to leverage modern-day .NET and Event Sourcing to move your monolith into a bright new future.
Event Sourcing from the Trenches (DDD Europe 2020)
Over the years I've spoken many times about what Event Sourcing is and shared many of the good, the bad and the ugly parts of it in blog posts and various talks. However, I've never talked about how to actually build a system based on this architecture style. I keep getting the same questions over and over again. Like when to apply Event Sourcing and at what architectural level. How to deal with transactional boundaries within and outside the domain. How to build projections that are autonomous, reliable and self-supporting. How to deal with upgrades and blue-green deployments. But also on how to handle bugs, design mistakes and crashing projections. Having made a lot of these mistakes myself over these years, it's time to share my current thoughts and opinions about this. Since the .NET space has a pretty rich set of open-source projections to support this, the examples and code will be .NET. But the concepts are universal, so don't let that scare you off.
Practical introduction to DDD, CQRS and Event Sourcing
After several in-depth talks about Event Sourcing, I realized that there's a large group of developers that may have heard about Domain-Driven Design, Command-Query Responsibility Segregation and Event Sourcing, but have not really connected the dots yet. So in this talk, I'd like to take a practical example of a simple domain and gradually introduce functional requirements to see how the principles behind DDD affect the way your entities are going to protect the business rules. After that, I'll introduce some real-world non-functional requirements and see if and how Event Sourcing and/or CQRS may or may not help to accomplish those.
How to practice TDD without shooting yourself in the foot
It’s 2019, so practices like Test Driven Development (TDD) have long found their way into organizations. However, the practices and principles to keep those unit tests maintainable haven’t really changed. Still, I regularly talk to developers that somehow ended up with an incomprehensible unmaintainable set of unit tests that they once believed in, but are now holding them back. So in this session I like to provide a refresh of those fundamental ideas and talk about why you should practice TDD, revealing intentions, naming conventions, state versus interaction based testing, and how to stay out of the debugger hell with proper mocking and assertion frameworks. And even if you believe you are well versed in the testing realm, join me anyway. Maybe we can learn some tips & tricks from the audience as well. Looking forward to it!
Decomposing the Monolith (Riga Dev Days 2019)
A micro-service architecture is a great strategy for decomposing a monolith. In this talk, I’ll show you some of the pros and cons of micro-services and how you can leverage OWIN, .NET, Event Sourcing and the Onion Architecture to gradually move your monolith into a bright new future.
If I have to name a single hype in software architecture land then I would have to mention the micro-service architecture. Micro-services are supposed to be small, have a very focused purpose, can be deployed independently, are completely self-supporting and loosely coupled. Ideally, micro-services are technology agnostic, but hey, we’re in the .NET space, aren’t we? And they are not a goal, but a means to an end. In fact, a micro-service architecture has many benefits and are a great strategy for decomposing a monolith. So how do you build a micro-service? What technologies does the .NET realm offer for us? And what if you don’t want to deploy them independently? In this talk, I’ll show you some of the pros and cons of micro-services and how you can leverage OWIN, .NET, Event Sourcing and the Onion Architecture to gradually move your monolith into a bright new future.

Lessons learned from two decades of professional software development
I recently was asked what I would do differently if I had the experience I have now. This got me thinking about the mistakes I've made, the traps I fell for and the dogmatism I became part of over the last 22 years of professional software developer in the Microsoft realm. In this talk, I'll be going down memory lane with you and share everything I've learned on architecture, tools, technologies, agile software development, maintainable code, automated testing, documentation and anything else that I think you should know. Prepare yourself for an event of stories, both good and bad.
The Good, The Bad and The Ugly of Event Sourcing
In 2009, I first learned about Event Sourcing and Command Query Responsibility Seggregation (CQRS) at a training Greg Young gave in Utrecht, The Netherlands. I remember being awed by the scalability and architectural simplicity those styles provided. However, I also remembered the technical complexity that comes with it. In 2012, I was in charge of transitioning a CQRS-based system to Event Sourcing. I knew it would be non-trivial, but boy was I in for a surprise. So, over the last four years, I've experienced first-hand how a large group of developers had to deal with the transition. It's a brilliant solution for high-performance or complex business systems, but you need to be aware that this also introduces challenges most people don't tell you about. In this talk, I'd like to share you some of the most powerful benefits of ES, but also show you the flipside of the coin and cover some of the smaller and bigger challenges you'll run into it. Again, I love it and would apply it again without any doubt, but I really want you to understand the trade-offs before you jump on the Event Sourcing train.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
Recycled Concrete Aggregate in Construction Part III
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

Hierarchical Digital Twin of a Naval Power System
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
