Evolutionary Design: Normalize Growth

Evolutionary Design: Normalize Growth

The Definitions

Evolutionary Design is the practice of creating the components and interactions of a system while it is evolving, on the basis of the client requirements and user needs.

Normalization refers to a process that makes something more normal or regular

Normalization may refer to more sophisticated adjustments where the intention is to bring the entire probability distributions of adjusted values into alignment from Wikipedia

Growth refers to a positive change in size, and/or maturation, often over a period of time from Wikipedia

 

The Moment

I am a big fan of gardening. Whenever I can, I take care of my plants and think about subjects like Evolutionary Design. One moment I was taking care of my young tomato plants: I needed to rip the small leaves that grow and just take the food away from the flowers and fruits. And it struck me: any gardener is doing Evolutionary Design.

Talk: Easier to change CODE

Talk: Easier to change CODE

This is a talk from I T.A.K.E. Unconference 2016, Bucharest.

It is a hands-on talk, where I refactor some code live with the help of the audience.

Interview by Lemi Orhan for Software Craftsmanship Turkey

We discussed about things like:

  • Well crafted code
  • Ways to improve one’s craft
  • How to become a conference speaker
  • and many more…

Automated Tests Purposes

Automated tests: Why? How they help? Who needs them?

There are many types of automated tests out there. Let’s see the most used types of tests and understand how each one is useful.

Types of tests covered are:

  1. Unit Tests are isolated, focused on methods and classes. White box tests.
  2. Integration Tests are for checking how two different modules integrate. Black box tests.
  3. Integrated Tests are big, large tests showing how many modules integrate, with a business purpose. Black box tests.
  4. Acceptance Tests are showing that a features works well. Black box tests.
  5. Contract Tests are a special type of tests, that verify polymorphism integration of multiple components or classes.

Let’s take them one by one in detail.

Hands-on Sessions: Performing Kata

Performing Kata

Blog Post Series

This is a series of blog posts about hands-on sessions you can facilitate at software conferences. You can find the rest of the hands-on sessions here.

Purpose

You can learn from someone who shows a live demonstration about a concept, technique or tool.

The idea of performing kata comes from martial arts. Its purpose is to teach a group how to tackle a specific problem in a systematic approach.

It is a very efficient way of conveying information because it is a mix of theory and practice.

Talk: Deliberate Practice at AgileWorks Bucharest

Talk: Deliberate Practice at AgileWorks Bucharest

Deliberate practice is a highly structured activity engaged in with the specific goal of improving performance. It is different from work, play and simple repetition of a task. It requires effort, it has no monetary reward, and it is not inherently enjoyable.

The common view held until recently was that expert-level performance was simply the result of talent and “natural abilities.” But scientists believe that expert-level performance is primarily the result of expert-level practice NOT due to innate talent.

So let’s have a discussion about how we can practice, formats and methods of practice in the Software Development world. I will touch technical type of practice (for programmers, testers, etc), and also organizational type of practice (managers, Scrum Masters, Team Leaders, Product Owners, etc)

Talk: Java User Group Łódź – Legacy Code is Fear

Talk: Legacy Code is Fear (Łódź, Poland)

This is a talk from last year, before Global Day of Coderetreat Lodz.

Legacy code is fear because we fear the unknown. Learn what you need to learn in order to be less scared about legacy code during this talk.

You are a programmer. Someone from the company comes with an idea to add a feature and they are sure this new feature is very easy to add. And it should be. But the code is old. The code is a mess. Nobody in the firm knows any more that part of the system. You need to change that ugly piece of code. You are afraid that you might introduce defects. Legacy code is fear.

 

Here are the slides for the talk Legacy Code is Fear:

The Coderetreat Book

The Coderetreat Book

About

A couple of weeks ago I published the Coderetreat book together with Alex Bolboacă. The book is about how to facilitate and host a coderetreat event.

front-cover

Contents

It contains plenty of ideas and advice from both of us, based on our experiences of organizing, hosting and facilitating many coderetreats the least 7 years. The book contains specific advice on how to host and facilitate. Also a list of sessions is available in the book. Each session is documented in detail.

This is the first edition of the book, and we launched it now especially for the Global Day of Coderetreat (GDCR) 2016. We hope this book will help hosts and facilitators have wonderful events around the globe during GDCR.

Feedback wanted please

We plan to enhance the book with more chapters and more sessions. For now just enjoy the book and we hope we will receive plenty of feedback from you. We want the book to help you if you are organizing, hosting or facilitating a Coderetreat. Please tell us if it helped you, or how we could improve it for you. Thank you!

Coderetreat: Programming by Wishful Thinking

Blog post series

This blog post is part of a series about coderetreat sessions.

Purpose

This session introduces the concept of top-down approach of Test Driven Development for a new feature.
By following the steps you will be able to understand how to add thin top-down features that you can show very fast to your customers. Many of the features will work, even though you will not have a fully functional system, just because you have used stubs or fakes for the parts of the system that are not yet implemented.
