Proceedings

The Pattern Languages of Programs, People, and Practices (PLoP) conference is a premier event for pattern enthusiasts to gather, discuss, and learn. Originally focused on software-related patterns and pattern languages, PLoP has expanded into all aspects of the built world—anything that is designed and made by people, including organizations, culture, and individual practice.

PLoP is organized by The Hillside Group. PLoP 2024 was held in cooperation with the ACM.

Preface

The last P in the PLoP's name now stands not only for programs, but also for people and practices. This decision, made at the Hillside Board meeting held at PLoP 2023, first affected AsianPLoP 2024. Although programs in the PLoP's name were meant more broadly than just computer programs, we felt it would be better to make this intention for interdisciplinarity explicit. It is worthwhile noting that Hillside Europe also recognized this trend and renamed EuroPLoP accordingly.

Nostalgia for Allerton as the original conference site will probably remain forever with those who had an opportunity to experience PLoP there, but we all knew PLoP needed a harbor that would allow it to grow (and also recede for a moment, if that happens). Skamania Lodge offers a similar sense of disconnection from daily life and connection to nature, while being a bit more accessible.

PLoP has always supported its participant in sharing their ideas and interacting over them in other ways. However, this effectively narrowed down to focus groups and lightning talks. For this PLoP, we invited the proposers of such sessions to let their imagination run wild. We ended up with 23 sessions: three plenary talks, one pattern mining session, one panel discussion, eight focus groups, seven workshops, and three lightning talks covering a range of trending and recurring topics. All of them were highly interactive, including the plenary talks. Making all this happen required close collaboration with proposers to find the format that suited them best.

Imagination run wild sessions attracted a number of participants who wouldn't participate in writers' workshops. We consider these sessions to be full-fledged contributions to the conference. While writers' workshops, introduced by Richard Gabriel in the first PLoP, remain the backbone of the conference, we felt we needed to let its muscles run wild a bit. To keep these two aspects of the conference together, we encouraged the organizers of imagination run wild sessions to take a peek at writers' workshop sessions and many of them did. We hope to see them soon as the authors of the papers discussed at writers' workshops. The authors of the papers were naturally attracted to imagination run wild sessions. It was a bit a challenge to make room in the program to let them do so. Now that we learned how to this, it would be easier to organize next conferences.
