Remote Pair Programming - the new trend sport

Podcast Rechenzeit - Episode 19

Keeping software development teams running under pandemic conditions - what better way in recent months than videoconferencing and related tools to keep team contact and develop software with each other remotely? But behind this, and especially behind pair programming from the home office, there is more than just a passing fad that will disappear again along with the pandemic situation. In this…

Test-Driven Development

Podcast Rechenzeit - Episode 18

Test-driven development (TDD), test-first approach - these are procedures that have been known for a long time and are also generally recognised. Unfortunately, we software architects on duty have the impression that TDD is not used in our industry with sufficient breadth and consistency. In this episode, we welcome Richard Wallintin, an upright fighter for the true and the good (meaning TDD…

A tool for music analysis - leitmotif: application orientation

Podcast Rechenzeit - Episode 17

In this episode, we computational time podcasters keep to ourselves: Holger asks Andreas about the story of his dissertation, which starts with Richard Wagner and Lohengrin, gets lost in a few shelf metres of score in the meantime, and finally comes out with a software tool for music analysis ("JRing") and a collaboration with Stanford University. In addition to providing insight into a…

Seven Pitfalls in Strategic Design (Part 2)

Podcast Rechenzeit - Episode 16

Strategic design is the part of domain-driven design that provides the decomposition of the domain into bounded contexts. In many software projects, this results in the concrete decomposition of a software system into modules or deployment units. Strategic design is therefore momentous, and at the same time it is difficult . This episode of Computing Time deals with the pitfalls number three to…

Clash of Cultures - Agile Projects and Classic Project Management

Podcast Rechenzeit - Episode 14

This episode of Computing Time looks at what happens when agile approaches and classic project management collide. Not infrequently a real "clash of cultures"! What are the lines of conflict, but what can we learn from each other? We will discuss these questions with the experienced project manager Carsten Lill, who has the "classic" epaulettes and at the same time has an agile mindset. Guest:…

Update... Privacy Shield 2.0 - on the way to Schrems III?

Podcast Rechenzeit - Episode 13

In this episode, together with lawyer Ralf Burmester, we look at the announced new "Privacy Shield 2.0" agreement between the EU and the US. In a sense, it is an "update" of the Computing Time Episode 9 from January 2022. Is it at all conceivable that anything other than a renewed negative ruling by the ECJ, which could bear the poetic name "Schrems III", will come out of this? Guest: Lawyer Ralf…

Model-Driven Architecture - a post-mortem analysis

Podcast Rechenzeit - Episode 12

In this episode we deal with a deceased, the "Model-Driven Architecture" (MDA). We examine this twenty-year-old approach of the Object Management Group together with our guest Andreas von Benten, who has decades of experience in model-driven software development. Andreas also explains to us in the podcast that MDA and Model-Driven Software Development (MDSD) are not the same thing, and that MDSD…

The Modulith - salvation for the monolith?

Podcast Rechenzeit - Episode 11

With the advent of microservices, the monolith has developed an image problem. A monolith with attractive inner values, the well-structured Modulith, is stepping up to save the honour of the mon olith. The question is whether, instead of the contrast between monolith and microservice, there is not a continuum of software architectures that have different degrees of modularisation, increasing in…

Dual+Discovery Track Scrum

Podcast Rechenzeit - Episode 10

While the programme with the mouse deals with how toothpaste gets into the tube, in this episode of computing time we want to know: How does the design get into the software? Under the dominance of agile process models, it has not become easier to answer this question. All the better that we welcome two guests, Sandra Wrengel and Dr Eugen Reiswich, who explain Dual Track Scrum as a possible…

When the Privacy Shield broke

Podcast Rechenzeit - Episode 9

The "Privacy Shield" broke down before the European Court of Justice on 16 July 2020. The agreement between the European Union and the United States was supposed to ensure that data could be transferred between the two economic areas in a legally secure manner. Without this shield, data worthy of protection from Europe can generally no longer be entrusted to American companies without the threat…

Domain-Driven Design goes mobile

Podcast Rechenzeit - Episode 8

In recent years, Domain-Driven Design (DDD) has gained importance as a design approach for microservice architectures, but originally pursues a broader and more fundamental approach. Accordingly, DDD can also be fruitfully used in the development of mobile applications. Our guest Jörg Pechau, with his company I.C.N.H., mainly deals with app development for mobile devices and has been oriented…

Gamification in quality assurance ("BINGO BONGO!")

In this episode of Rechenzeit, we look at how playful elements can help us motivate teams and experts to develop and test software even better ("gamification"). Our guest is Dr. Dehla Sokenou, who tells us about her experiences with gamification - and in particular explains what is behind the name "BINGO BONGO". Guest: Dr Dehla Sokenou

The quantum computer

While quantum mechanics fascinates laymen and learned physicists alike and is suitable for small talk and headaches of all kinds at parties (at least at certain parties) - how soft is the fur of Schrödinger's cat? -, the quantum computer has now arrived in the news and the attention of a technology-interested public. In this episode we welcome Prof. Dr. Jörg Hettel as our guest, who began his…

In October 2021, the book on Domain Storytelling will be published by…

The Blockchain - Yesterday's Silver Bullet?

Podcast Rechenzeit - Episode 3

The blockchain is the focus of this computing time episode. After blockchain technology has been known for several years, but the expectations of its widespread use have not yet been fulfilled, we still observe a flare-up of the blockchain hype every year. Is there perhaps more to it than that - or does the blockchain remain just "Yesterday's Silver Bullet"? We talk about this topic in detail…

Orientation scenarios in Domain-Driven Design ("We'll always have Paris")

Podcast Rechenzeit - Episode 1

In this episode, Holger and Andreas welcome domain-driven design coach Jörn Koch, who introduces the concept of orientation scenarios. Orientation scenarios are an effective means of finding the contextual cut in the context of DDD and, in doing so, provide a guideline for the upcoming development tasks for usually several software development teams involved. In a good three-quarters of an hour,…

In this episode, we look at the evaluation of software architectures that we find in existing, productively deployed systems. Our guest Johannes Rost, who has years of extensive experience in conducting such reviews, gives us procedures and techniques for this task, and shares one or two anecdotes. The discussion becomes particularly exciting when it comes to the extent to which software systems…

Software Architecture - Assessment with the Modularity Maturity Index (MMI)

Podcast Rechenzeit - Episode 22

People interested in how to evaluate a software system in terms of its software architecture and engineering quality often want (in addition to a detailed and differentiated analysis) to condense the evaluation to a single value, comparable to a school grade. The MMI (Modularity Maturity Index) represents such a metric for software systems . In this episode, we discuss with Dr Carola Lilienthal,…

Stories of suffering

Podcast Rechenzeit - Episode 23

Time and again, we have noticed that the interest in testimonials that deal with real problems is significantly higher than that in smooth success stories.
That's why in this episode we gather with our guests Dr. Dehla Sokenou and Dr. Peter Rüppel around a virtual bonfire to share "tales of woe": failed projects, derailed architectures, crashing software.
Surely it is no coincidence that literary…
