Advanced Kustomize features

Kustomize’s strength lies in its simplicity, but now and then we have use-cases that need more flexibility and more dynamic behavior. For some of them, Kustomize offers additional features. But as with everything good, it should be used wisely. Otherwise, we fall into the trap of complexity and lose all the good parts of Kustomize.

Infrastructure Self-Service with Crossplane

Introducing container technology and Kubernetes to the development and deployment process allows developers to independently manage deployments of their services without needing to interact with the platform team. This is true for applications but not necessarily for external resources like databases which are probably still in the hands of the platform team because the access management and tooling differs. Crossplane could fill this gap towards a full self-service capability.

Dependently-Typed TypeScript

TypeScript is a programming language with some special features: Unlike most other typed programming languages, it was developed as an add-on for JavaScript (JS). In the process, Microsoft has placed great value on ensuring that the language integrates as seamlessly as possible into the existing ecosystems (Node.js and browser). TypeScript’s syntax “merely” adds types to JavaScript, while the compilation “merely” removes the type annotations. This has made TypeScript the de-facto standard for building type-safe JS-based applications.

cards42 English edition

Finally, cards42 is available in English! The cards42 project supports software developers in your daily work with software architectures. 30 cards provide brief food for thought for stuck situations and help shed new light on difficult challenges. This article provides detailed explanations as well as the background and further information about the cards.

Rich code documentation with Jekyll

Customer-specific documentation with Jekyll

Static site generation is a perfect fit for publishing documentation. In a recent project, we chose to use Jekyll for rendering our content. As a special requirement, we had to build different “flavours” for different customers.

Data Mesh: Decentralized Data Analytics for Software Engineers

The decentralized data architecture approach Data Mesh is designed to enable developers to independently perform cross-domain data analysis.

TypeScript – Taming the Complexity of JavaScript

TypeScript celebrates its tenth anniversary in 2022. A good reason to look back at its beginnings – and to provide beginners with everything they need to know for working with this programming language.

INNOQ and Family

Managing Kubernetes Resources with Kustomize

Helm is the de-facto standard for managing groups of Kubernetes resources that belong to an application as a package. It comes with its own ecosystem to build, configure and distribute these packages. In some cases, this is an appropriate approach but sometimes we just want to manage our resources as yaml files and need a simple way to slightly modify the resources for different environments. In this article we will have a look at how Kustomize can help us with this.

Fairness and Artificial Intelligence

Classical software testing cannot simply be transferred to AI. Model governance and internal audits are required to ensure fairness.

CORS extension “Private Network Access”

Chrome rolled out the “Private Network Access” extension for its CORS handling. Let’s try to understand the why and how this is affecting us.

Ethics and Artificial Intelligence

Artificial intelligence is forcing its way into many fields of application. Now it is important that it works in a responsible, secure, and transparent way. The regulation of AI systems is a legal, societal, and technical topic that demands broad awareness and that will become increasingly important in the years to come.

Libraries for command-line applications

Command-line applications are admittedly not the most common due to the start time of the JVM. Their development for internal applications can however be appropriate, depending on the level of knowledge of the team. And thanks to the native compiling with GraalVM, the start time is accelerated. Much of the work involved in a command-line application involves parsing and use of the provided arguments and options. We look at four possible libraries that can assist us.

Awesome presentations deserve beautiful code

Occasionally we need to put parts of our source code onto slides for presentations. The common presentation programs (such as PowerPoint or Keynote) fail miserably at this task because they interpret code as normal text. Syntax highlighting is lost, as are indentations. It looks lousy, and it’s no fun. This post introduces carbon.now.sh, a quick and free solution, created by the awesome people from @carbon_app.

A Comparison of Java HTTP Clients

In addition to databases, communication via HTTP to other services is nowadays found in almost every project. A large number of libraries have been built within Java that can be used for this purpose. In this article we will take a closer look at four of these candidates and see in which aspects they differ from one another.
