Type-safe SQL queries in Java and Rust

In recent years, our industry has been in favour of strong typing and build-time verification to make certain classes of bugs impossible. How much influence has this trend had on how we can write SQL queries in Java? Let’s look at how typesafe SQL queries can be in Java, how this compares to what you can do in Rust, and consider the benefits and drawbacks of these different approaches.

Nicht mehr Open-Source

Was kann man tun, um sich vorab dagegen zu wappnen, plötzlich für eine wichtige Technologie einem Anbieter ausgeliefert zu sein? Kann es auch eine valide Entscheidung sein, das Risiko bewusst in Kauf zu nehmen? Und sind die Risiken, die sich bei Verwendung von Open-Source-Technologien ergeben, per se geringer als bei kommerziellen Alternativen? Wie geht man damit um, wenn eine Technologie, die man verwendet, plötzlich nicht mehr Open-Source ist? Ist es sinnvoll, zu einem Fork zu wechseln, und welche Risiken bestehen dabei?

Type-safe HTML templates in Java and Rust

The current fashion in our industry is to use static and strong typing wherever possible. How fashion-conscious is the Java community when it comes to HTML templating, though? Let’s have a look at what approaches at type-safe or build-time verified HTML templating are available in the Java ecosystem, how they compare to what’s available in Rust, and whether the benefits outweigh the costs.

One of the main tasks that business sets for IT as an industry is the creation of effective software, according to criteria that clearly meet the needs of this business. On the other side, one of the main prerequisites for achieving the goals that a business sets for itself is the ability to hire specialists who can create a product in the shortest possible time and/or effectively maintain it. Accordingly, to achieve this, the technology stack used, i.e. tools, must be mature enough, and widely used in the market.

Type-safe HTTP routing in Java and Rust

In recent years, the trend in our pop-culture industry has been to favour static and strong typing as well as build-time checks over dynamic typing and techniques like late binding. Where possible, you are expected to use the compiler for correctness checks instead of unit tests. Even though the Java language is statically typed, its type system is often considered to be not very helpful. Web applications written in Java are traditionally bristling with weakly typed APIs, heavy use of reflection, and lots of annotations that are interpreted at runtime. Let’s see how far the trend towards build-time checks has been adopted in the Java ecosystem when it comes to writing web applications, how it compares to what’s done in the Rust community, and what benefits and weak points these techniques have.

Unternehmen streben häufig eine Modularisierung (wie durch Microservices) an, die Teams unabhängiger voneinander arbeiten lasst. Dabei ist aber ein reines Aufteilen der Applikation in verschiedene Module/Container/Bausteine nicht ausreichend. Die Abhängigkeit oder Unabhängigkeit entscheidet sich vielmehr mit der Gestaltung der Schnittstelle, genauer: Mit der Frage, ob die gewählte Schnittstelle fachliche Implementierungsdetails preisgibt oder diese versteckt.

Bestehende Rich Clients erneuern

Oft gibt es Rich-Clients die als Backoffice-Applikation wichtige Funktionen erfüllen und nun Probleme machen: egal ob es um Support für mobile Geräte oder um einfaches Arbeiten von zu Hause geht oder auch nur um das Sicherstellen der Weiterentwicklung – Rich-Clients kommen mit Ihren eigenen Problemen. Ob die richtige Antwort für die Modernisierung solcher Applikationen immer die Migration zu einer Webapplikation ist, wollen wir in diesem Artikel beleuchten.

Fundamentals of software architecture: Part 4

In this (fourth) installment of the mini-series on software architecture, we explain who might carry out the architecture tasks that were discussed in the previous articles. I also present a number of possible role definitions for software architecture along with their pros and cons.

Communicating organizational changes with “Team Topologies”

Whenever the need arises to set up a new team, split a team into two or move responsibilities between teams it is necessary to have a good idea of where you are and where you want to be after the change. Additionally to the current and final states you will very likely have phases with intermediate states. To help everyone involved to have a shared understanding of which phases you will transition through - and when responsibilities and communication channels have to be created or changed - a visual representation of these states can be used to paint a (literal) common picture.

Technologies for the Integration of Services

In the course of an internal study, we asked a number of INNOQ consultants about their experiences in current or past development projects. One interesting topic here was the integration of microservices and self-contained systems (SCS). Asynchronous communication is frequently used in distributed systems to enable better scalability, greater resilience, and looser coupling. In this article, you will read what insights we learned in our conversations.

Fundamentals of software architecture: Part 3

In this part of the mini-series, we explain everything you need to do when creating software architecture. First, we take a look at the necessary tasks and activities. Then we discuss some of the skills and capabilities required for these architecture tasks.

Extending the OpenTelemetry Java Agent for Spring Auto-Instrumentation

OpenTelemetry is great. A few days ago, I was diving a bit more into the intrinsics of the OpenTelemetry standard and the Java auto-instrumentation in particular.

Zukünftige Features des JDK

Ich weiß nicht, wie es Ihnen geht, aber seitdem mit JDK 9 der Release-Zyklus des JDK auf sechs Monate verkürzt wurde und wir mittlerweile, dank Preview und Incubator, auch Features bereits vor der vollständigen Fertigstellung ausprobieren können, wirkt das JDK lebendiger als eh und je. In diesem Artikel wollen wir deswegen einen Blick in die Zukunft werfen und uns aktuelle Preview-Features anschauen, die es vermutlich in naher Zukunft final ins JDK schaffen werden.

Wie KI meine Programmierarbeit revolutioniert

The Evolutionist

The current training and further education of software developers strongly focuses on the development of new software. Conferences and trade magazines are full of new programming languages, new tools, new hypes, which seemingly never cease to amaze. Quick results, direct feedback, and unprecedented productivity are suggested. The urge to incorporate the new into one’s software is awakened – until one is brought back to reality: their own legacy system.

Welcome to the first part in the mini-series on software architecture. We start by examining the original source of the term – since the word architecture presumably conjures in most people thoughts of buildings.
