Talks

Why Event Sourcing is necessary, in what situations it is useful, and in what situations it can create unnecessary complications. The most common approaches to implementation, typical pitfalls, real advantages and disadvantages. The most popular misconceptions associated with this template.

Let's imagine ourselves as developers facing the task of integrating the .NET platform with a new DBMS. What are the key aspects and issues to be considered for successful integration?

Do you want to search through the knowledge base or embed AI into some of the processes of an existing .NET solution, but you don't want to add any other languages to the solution? I have good news for you: everything is already done for .NET!

You will learn how references and arithmetic operations with managed pointers are implemented. We will look “under the hood” of runtime and delve into the world of low-level code optimizations.

Over the last 5 years, thanks to technological advances and import substitution, the popularity of ReactiveUI and Avalonia UI frameworks has increased significantly. Let's take a look at how these frameworks can improve applications, whether they promote cross-platform and how to improve a desktop WPF application using them.

Let's figure it out and find the best solutions!

Do you already know how to deploy applications to K8s, but feel like every new commit to the cluster is a leap into the unknown?

Let’s dispel that magic! We’ll dive “under the hood” to see what containers, Pods, Service, and Ingress really are, and prove that Kubernetes isn’t witchcraft but a rather simple — and in its own way beautifully designed — piece of software.

In this talk, I will clearly explain and offer a well-defined approach to build a monolith modular application that is easy to transform into a microservice system later.

We have all been living in a world where distributed systems have become the norm for a long time. And the ability to design them is a necessity.

Using the example of a real-life fintech task we will:

1. Look at different implementation options for the Transactional Outbox pattern.
2. Discuss how to implement delivery guarantees, including exactly-once delivery.
3. Figure out how to process messages in the right order.

I recently took part in the implementation of UUID for Postgres and figured out the topic. I will tell you about the UUID (universally unique identifier), mathematical, philosophical and engineering issues that arose during the design of this technology. And also about my work on UUID v7 for Postgres and about .NET implementations.

How sharding can be implemented on a live service with zero downtime. Key takeaways on what to watch out for — so you don’t have to go through this complex process over and over again.

We will dive into the practical aspects of the methodology, analyze a real case study and learn to identify key events that shape the business logic. You will be able to design your own system, applying the knowledge gained in practice and working in a team.

A talk on trying to surpass Hangfire and Quartz and develop a proprietary library for storing and running background tasks with a focus on high performance, optimal resource consumption, use in distributed systems, and resilience to failures.

Practices of transferring personal data via data buses using Kafka as an example. Encryption at JSON-serialization level. Key storage in HashiCorp Vault.

JIT in .NET is a powerful but sensitive tool. In order for it to reach its potential, you need to understand how it works. We will look at its development path, key optimizations, and limitations at the code level. We will learn how to systematically help JIT in highly loaded scenarios.

I'll show you what System.Security.Cryptography actually does on Windows, Linux, and macOS. I will show vulnerabilities of typical defaults AES-CBC, RSA-2048, PBKDF2. I will offer secure analogues of the same classes: AEAD-modes, RSA-PSS/OAEP, “long” PBKDF2 or Argon2, as well as modern additions ChaCha20, SHA-3 and the first post-quantum KEM. I'll wrap up with a checklist on “How to configure properly”.

How to implement request and response body transformation in YARP.

Report on working with geodata, in particular on the k-NN algorithm for finding nearest points in space. We will consider both search in rectangular coordinates and in coordinates on the globe, for which PostGIS will be needed.

Razor is an extremely flexible and convenient markup language native to the .NET ecosystem. Let's learn how its compiler works and how it can be used to create your own custom compilers from Razor in Blazor components and beyond!

How to organize fast search output with filtering? We put data on a binary diet and intensive Redis training. Then we'll use bitmaps to make data even more compact, but without losing processing speed.

In microservice interaction, it is required to transfer data between programs. For this purpose, there is a profession named after the most popular format has emerged — data stacker. What awaits the data stacker in the next stage of his career? A world of experimental binary formats with incompatible implementations.

During the master class we will together define what variants of cutting a monolith can be, break an existing monolith into limited contexts, and design several steps for taking parts out of a monolith. We'll also invent some patterns and discuss the pros and cons of the implementations.

How we solved the problem of clustering events with text fields in C#. 30 000 pieces in 200 ms: stages, testing solutions and our own bike.

When it comes to threads, developers often say that .NET threads are their own, “thin” threads. And that they are much lighter than operating system threads. I will dispel myths and tell you about the real capabilities of this mechanism.
