The Silver Bullet Syndrome

We love our silver bullets don’t we? Constantly chasing the dream that the next big thing will solve all our past problems. It doesn’t matter if it’s a language, framework, platform or library, we’re out there chasing it. Why? Well because it’s going to solve our needs, it’s going to solve the business needs. Well supposedly it will. And how much is it going to cost? Not that much, especially if we’re not the ones paying the bills. It’s about time we look at the hard facts and ask those difficult questions. Are we really looking for a silver bullet? Why are we constantly riding the technology bandwagon? Where is the churn going to take us? And at what cost?

Effective Microservice Communication and Conversation Patterns

Orchestration or Choreography? Sagas or process manager? REST, RPC or Events? Are we just making this all up as we go along? Once we move away from a single process to many services and processes, we immediately hit the problem that our services need to communicate with each other. The architect mandated REST! But then nothing worked in production. Then came events! And nothing ever completed. In this talk we'll look at the problem from a holistic perspective - take the fundamental property of autonomy for any microservice-based architecture, and design how services should communicate so that they can still achieve their purpose in the world. We'll cover basic communication patterns, where we run into problems with them, and how advanced conversational patterns can help. Finally, we'll look at some real-world scenarios for designing complex coordination and where conversation patterns can retain our autonomy and loose coupling.

Refactoring with Exuberance

When is it okay to build an orbital laser to destroy an ant-hill? Many cry "overkill" when design principles are applied to trivial problems. And for good reason: in the context of work, excessive embellishment gets us into trouble. Complexity costs us time and money. This talk explores how stepping outside of the realm of work and applying outrageous engineering practices to toy problems can deepen our understanding of the trade-offs that we make. Comically simple problems provide the perfect ground for developing actionable heuristics which can be applied to those monstrous complexities that we face in the real world.

Things Every Developer Needs to Know About Database Indexing

This talk dives deep into a topic that I believe developers don't know enough about: database indexing. There are four sections to this talk: - What's an index? * How to create an index? * Understanding the execution plan * Common pitfalls What's an index In the first part we will learn what an index actually is. And we're talking data structures. How is an index actually represented internally and what are the implications of that. This is important because it makes certain characteristics of indexes much easier to understand.

The World Needs Full-Stack Craftspeople

Developers and IT people in general tend to specialize and become narrowly skilled. In the past there was always the conflict of DB developers vs application developers, or DBA vs developers vs testers. Nowadays developers split even more into front-end/back-end/Android/iOS/whatever else. This leads to inflated teams, inefficient communication, lack of each developer's responsibility, low team's truck factor, and inability to solve production/design problems once and for all instead of applying patches here and there. The term "full-stack" is often applied to developers being responsible for all aspects of their work, but XP/craftsmanship practices go further — we should also take our communication, requirements, operations, testing, etc. under control. True сraftsmen can be an order of magnitude more efficient than narrowly skilled developers. They not only write code, but solve problems. Surely you want to be one. Let's break it down and see why it works.

Prioritizing Technical Debt as if Time and Money Matters

Many codebases contain code that is overly complicated, hard to understand, and hence expensive to change and evolve. Prioritizing technical debt is a hard problem as modern systems might have millions of lines of code and multiple development teams -- no-one has a holistic overview. In addition, there's always a trade-off between improving existing code versus adding new features so we need to use our time wisely. So what if we could mine the collective intelligence of all contributing programmers, and start to make decisions based on information from how the organization actually works with the code? In this presentation you'll see how easily obtained version-control data let us uncover the behavior and patterns of the development organization. This language-neutral approach lets you prioritize the parts of your system that benefit the most from improvements, so that you can balance short- and long-term goals guided by data. The specific examples are from real-world codebases like Android, the Linux Kernel, .Net Core Runtime, and more. This new perspective on software development will change how you view code.

Certainly Uncertain: Predicting Delivery Dates

As soon as you become a team lead or manager, you immediately become responsible for making vague things certain. When you have no idea what exactly shall be done, you are asked how much it costs and how long it will take. When you give an estimate and commit to delivering to your promise, scope creeps and enjoy estimation hell again. In this talk, you will learn how to estimate without screwing things up. I will be as practical as possible and will share the real Excel-spreadsheet that implements a simple statistical model of project estimation so you can use it for your projects the next day.

The Soul of Erlang and Elixir

Whether you're developing a small web site or a large-scale distributed system, Erlang and Elixir are great tools for building server-side systems. Both languages can help you start quickly and deal with highly complex problems at a large scale. This talk aims to explain what makes Erlang and Elixir suitable for such tasks. We'll look past the syntax and the ecosystem, focusing instead on the concurrency model of these languages. Combining a bit of high-level theory and a couple of demos, we'll examine some important properties of Erlang/Elixir concurrency, with a special emphasis on why these properties are very relevant when building highly available systems. The talk targets experienced backend developers, but no knowledge of Erlang or Elixir is required. You will walk away from the talk with a better understanding of what distinguishes Erlang and Elixir from the rest of the pack, and why these languages are very compelling choices to power your next software system.

The Effective Developer

We’re agile, we’re doing DevOps, we work in cross-functional teams, and we use the latest developer pipeline tooling. With all those methodologies and technologies we should be highly effective, right? Probably not. Most of us still struggle with balancing coding speed and quality, working on the stuff that really makes a difference, and feeling constantly stressed by all the things we should learn. Effective developers don't just write clean, simple, and robust code. They also have a strong understanding of the entire development process and the problem that needs to be solved. They take time to learn, practice, and play. Learn how those developers build effective coding habits, use automations whenever needed, reserve time for deep work, and much more. You’ll walk away from this talk with lots of ideas on how to work smarter, not harder.

Leadership Guide for the Reluctant Leader

Regardless of the technology you know, regardless of the job title you have, you have amazing potential to impact your workplace, community, and beyond. In this talk, I’ll share a few candid stories of my career failures… I mean… learning opportunities. We’ll start by debunking the myth that leadership == management. Next, we’ll talk about some the attributes, behaviors and skills of good leaders. Last, we’ll cover some practical steps and resources to accelerate your journey. You’ll walk away with some essential leadership skills I believe anyone can develop, and a good dose of encouragement to be more awesome!

Functional Domain Modeling – How to Make Your Architecture Scream

We might have heard that Domain Driven Design is Object Oriented done right. Is it, however, always true? Thinking of business processes as workflows and pipelines lets us map our problems into the concepts of functional programming, thus bringing our code to another level. During this session we will apply bits of functional programming into our Java application, discussing their impact, including security, testability, readability, and more.

Power Workshops Day II, 4 Dec

Our instructors are here to deliver full-day workshops from 9:00 to 18:00. Learn directly from industry experts:

{ 2/4 } From Legacy to Solid Code with Blue-Green Refactoring (limited seats)

refactoring event storming java examples

Course description

Most of us have been working with some kind of legacy systems with lots of technical debt. How do we improve the codebase without The Big Rewrite and avoid creating yet another spaghetti monster? That’s what this workshop is about.

In this workshop, we will work together on a legacy system. We will approach the problem by creating a new, clean, and truly object-oriented model with modularity, cohesion, and testability in mind. We will introduce the model into the existing application in a secure manner, leaving ourselves an option to withdraw changes at any point in time. Fully automated tests will make sure that both models produce consistent results. EventStorming will help us set priorities right and understand the business impact of our changes.

Finally, we’ll get a solid, clean, and object-oriented code aligned with the company's goals and agile software development best practices.

Instructor

What you'll learn:

  • Why do we refactor, when do we do it, and where
  • What are the pros and cons of small-steps refactoring compared to blue-green refactoring?
  • How EventStorming can help us create the new model
  • How to split logical modules from the existing codebase
  • How and when to refactor towards DDD
  • How to test your legacy code and identify seams
  • How to be sure that the new code works exactly like the old one
  • How to securely withdraw changes when something goes bad
Book

{ 3/4 } Modular Monoliths vs. Distributed Synchronous Systems vs. Event Driven Systems (limited seats)

architecture microservices modularity

Course description

In this workshop, I’ll take you through 3 different architecture styles. We will design a non-trivial system and find out the strengths and weaknesses of each approach. We will discuss the typical design errors, problems and solutions. We will finally learn how to create a hybrid solution, and how what to optimize our architecture for.

During this workshop we will be working with a C4 model. If you don’t know it, do not worry, it’s simple enough to master in 15 minutes. This workshop is technology agnostic, but we will focus on the backend architecture and services.

Surprising as it is, this workshop can also help Product Owners and Managers to communicate with their teams. At least that’s the experience we’ve had so far.
