[podcast]Devnology Podcast 025 - Kevlin Henney

podcast@devnology.nl (Devnology) — Wed, 08 Feb 2012 07:06:00 +0000

In this episode we talk with Kevlin Henney, an independent software development consultant and trainer from the United Kingdom, well-known from one of his books '97 Things Every Programmer Should Know'. In the interview we discuss a wide variety of subjects in software development, like the agile community, patterns, learning and languages.

Kevlin shares his thoughts on the software craftmanship movement and states his opinion on the discussion whether our profession is a form of engineering or not. In some parts of this discussion we refer to the Hot-or-Not presentation that Kevlin gave the night before the interview at Sioux, the Netherlands. You can find the slides of this presentation here.

The interview was recorded at the hotel 'la Sonnerie' in Son & Breugel. We would like to thank the hotel for their hospitality by providing the chapel as a recording room for the podcast.

Links for this podcast:

Kevlin (co) authored two books of the Pattern-Oriented Software Architecture serie: volume 4 is a worked example of patterns for distributed computing and the 5th volume is a book on the concepts of patterns.
In the podcast Kevlin refers to a famous quote of Jason Gorman: 'Software craftsmanship's not the "next big thing". It's an attempt to articulate what the "thing" always was'.
Scrum can be seen as a 'Nomic' game, which is a game in which changing the rules is one of the rules.
In a presentation called 'With Economy and Elegance - Software Engineering reclaimed' (slides here) Kevlin explains that Software Engineering is a form of engineering and a craft - following his claim there are no contradictions.
Glenn Vandenburg explains what is wrong with the way Software Engineering is taught at universities in the presentation called 'Real Software Engineering' (video here).
Software development is all about passion and fun. An example of passion is the Tenet of Professionalism from Uncle Bob: 'Work 40 hours for your employer and another 20 hours improving yourself'.
A great example of fun and playfulness in our industry is 'the Globe', a piece of Ruby software which rotates itself.
Another way to look at your code is with a tag cloud of all words used in a piece of software. This idea was proposed by Phillip Calçado.

[podcast]Devnology Podcast 23 - Continuous Delivery

podcast@devnology.nl (Devnology) — Sun, 27 Nov 2011 20:31:00 +0000

In this episode we interview Dave Farley and Jez Humble about the content of their award-winning book on Continuous Delivery.

The basic premise of the book is that we need to move beyond Continoous Integration and occasional delivery and work towards practices that allow for the creation and deployment of final deliverables on all environments on every check-in. Jez and Dave explain the concepts behind the deployment pipeline and we discuss the practices and policies that come into play from the moment of check-in to updating the live version of software.

We talk about various strategies and patterns for testing, building and releasing software, and how these fit in with agile and lean software development.

[podcast]Devnology Podcast 021 - Nat Pryce on Growing software with Tests

podcast@devnology.nl (Devnology) — Wed, 24 Aug 2011 19:24:40 +0000

Nat Pryce is an early adaptor of eXtreme Programming and a contributor to several open source libraries and tools supporting Test-Driven Development, like jMock. In this episode we discuss several topics from the book 'Growing Object-Oriented Software, Guided by Tests' that he wrote together with Steve Freeman. We talk about the 'Londen-style' of Test-Driven Development, using mock objects to drive your design, listening to your tests and dependency injection.

Nat's personal blog 'Mistaeks I Hav Made' is on http://www.natpryce.com/ and you can follow him on twitter via @natpryce.

This interview is recorded on June 14th at the Software Practice Advancement conference (spa2011) in London. Interview by @freekl and @arnetim. Audio post-production by @Mendelt.

Links for this podcast:

The roots of the 'Londen-style' of Test-Driven Development can be traced back to the eXtreme Tuesday Club (XTC). A weekly London (pub) meeting that started more than 10 years ago.
On his blog Nat visualizes different kinds of tests that drive the design of a software system.
In the podcast we discuss the blogpost 'Whose domain is it anyway?' of Dan North.
Nat completed his PhD thesis in 2000: 'Component Interaction in Distributed Systems'. A lot of his thoughts on object-orientation and messaging between objects and peers that is described in the book, can be traced back to his early research.
In order to improve the testability of your software, Steve and Nat propose to apply the Ports and adapter architecture from Alistair Cockburn. You can read more on this subject on the wiki of Alistair.
Use Hamcrest Matchers to improve the readability of your tests: learn more from this tutorial.
While the use of Dependency Injection is widely spread in the software engineering community, Nat considers applying this style harmful. On his blog you can read more of his thoughts on this subject.
In 2004 Steven and Nat published the article 'Mock Roles, not Objects' in which they introduces jMock.

[podcast]Devnology Podcast 004 - Jurgen Vinju

podcast@devnology.nl (Devnology) — Tue, 22 Dec 2009 05:00:00 +0000

De grote berg met software op deze wereld neemt explosief toe. Als ontwikkelaar krijg je steeds vaker te maken met het onderhoud van bestaande software waarvan je de complexe programmacode niet altijd direct kan begrijpen, omdat het bijvoorbeeld slecht is gedocumenteerd. In deze Podcast legt Jurgen Vinju uit hoe de domein specifieke taal Rascal jou een geavanceerde gereedschapskist kan bieden om jouw programmacode te analyseren en / of automatisch te transformeren. Jurgen geeft op basis van zijn ervaringen met het ontwikkelen van een DSL zijn kritische blik op het gebruik van de domein specifieke talen en rekent af met 'embedded DSL's', UML en XML.

Jurgen Vinju is senior researcher bij het Centrum voor Wiskunde en Informatica en actief als docent aan de Universiteit van Amsterdam. In de Master Software Engineering is Jurgen actief als docent op het gebied van Software evolutie en Software constructie. Je kan de publicaties die Jurgen heeft geschreven vinden op zijn website; zijn dagelijkse activiteiten volg je op Twitter: @jurgenvinju.

De Domein specifieke taal Rascal.
Als iedereen alleen maar bezig is met het schrijven van software abstracties, dan wordt er geen werkende software meer geschreven, stelt de Turing Pit.
ASF+SDF is de vormalige taal, die aan het Centrum voor Wiskunde en Informatie is ontwikkeld, om source code te analyseren en transformeren.
Software ontwikkeling is complex, omdat het tracht een probleem op te lossen in een omgeving waarin de eisen aan de oplossing constant veranderen: Wicked design.
Een Embedded DSL (ook wel: Internal DSL) is een taal die onderdeel uitmaakt van bijvoorbeeld een general-purpose taal als Ruby.
