Technical debt is a financial metaphor describing the tradeoff between the short term benefits gained and long term consequences of design and implementation shortcuts taken over the evolution of a software product. These shortcuts typically manifest as design disharmonies such as code smells, anti-patterns, design pattern grime, modularity violations, or violations of good coding rules. Curren...

We propose a research plan to further the understanding of design pattern evolution. Current research into design pattern evolution focuses on the structural elements of decay, which is realized as structural grime. We plan to expand the current state of research by introducing the notion of behavioral grime, or unwanted artifacts that appear at run-time in a pattern. This form of grime may be ...

Impervious surfaces are ubiquitous in urban environments and constitute a substrate onto which atmospheric 10 constituents can deposit and undergo photochemical and oxidative processing, giving rise to “urban grime” films. HNO3 and N2O5 are important sinks for NOx in the lower atmosphere and may be deposited onto these films, forming nitrate through surface hydrolysis. Although such deposition ...

Design patterns are well known solutions to common problems and are extensively utilized in software development. Yet, little empirical work has been conducted to evaluate or validate the consequences that poor design decisions have on pattern realizations. This paper describes a research program to further the understanding of design pattern evolution. Specifically, we focus on design pattern ...

Context: GoF design patterns are popular among both researchers and practitioners, in the sense that software can be largely comprised of pattern instances. However, there are concerns regarding the efficacy with which software engineers maintain pattern instances, which tend to decay over the software lifetime if no special emphasis is placed on them. Pattern grime (i.e., degradation of the in...

Grime music is an Afrodiasporic performance form originating in London. While artists such as Stormzy and Skepta are now international stars, its gestation took place within a grounded network of record shops, radio stations raves. This article argues for grime pirate radio’s role both oppositional channel site creative practice. Based on empirical work undertaken from 2017 to 2019 London’s sce...
