PLoP
Pattern Languages of Programs, People, and Practices (PLoP®) is the premier conference for pattern authors and users to gather, discuss and learn more about patterns. To achieve this, the conference promotes the use of patterns and pattern languages, as well as the underlying theory of the nature of order. PLoP 2024 will be held October 13-16, 2024.

The Hillside Mission
The mission of the Hillside Group is to improve the quality of life and society as a whole. This includes architects, developers, managers, owners, workers, educators, students, and more. Understanding and helping the human element is critical for achieving success. The Hillside Group believes in making processes and design more humane by paying attention to real people and existing practices.
The Hillside Group promotes the use of patterns and pattern languages to record, analyze, and share knowledge to help achieve its mission. The Hillside Group sponsors a variety of activities to achieve this mission—organizing workshops, hosting PLoP (pattern) conferences, and producing publications for discussing, recording, and documenting successful practices.
The Hillside Group supports many different conferences such as: PLoP, EuroPLoP, AsianPLoP, VikingPLoP, SugarLoafPLoP, and ChiliPLoP. These conferences focus on writing groups to better improve patterns through group exposure. Each conference offers advanced topics for the more adept pattern writers. Participants have the opportunity to refine and extend their patterns with help from knowledgeable and sympathetic patterns enthusiasts.
Pattern Books
The Design Patterns Book Series showcases many patterns from PLoP conferences and leading experts in the patterns field.
See our Pattern Book Library filled with over 80 Pattern related books.

This email address is being protected from spambots. You need JavaScript enabled to view it. is for presenting and creating patterns about decoupling systems and managing complexity so that an architecture can be implemented in the context of organizational constraints. Of particular interest are:
- applications of "classic" patterns, like those in Design Patterns to the problem of designing an architecture to facilitate groups working together, and
- new patterns, perhaps combining GOF patterns, to achieve the same goal.

This email address is being protected from spambots. You need JavaScript enabled to view it. is a software development forum for the theory and practice of AntiPattern recognition and AntiPattern refactoring. AntiPatterns is a branch of design patterns research that documents negative solutions and their resolution through refactoring. Well known AntiPatterns include: Spagetti Code, Analysis Paralysis, and Stovepipe Systems. These and other AntiPatterns are documented in the book: W.J. Brown, H.W. McCormick, R.C. Malveau, and T.J. Mowbray, "ANTIPATTERNS: Refactoring Software, Architectures, and Projects in Crisis" , John Wiley & Sons, 1998. AntiPatterns research spans software design, software architecture, and software project issues, including both formal and informal refactoring techniques. The purpose of This email address is being protected from spambots. You need JavaScript enabled to view it. is to promote the general understanding of AntiPatterns and related extensions of design patterns research.

Welcome to the patterns home page. It is a source for information about all aspects of software patterns and pattern languages. If you are new to patterns, James Coplien and Richard Gabriel have created a succinct pattern definition.
Patterns and Pattern Languages are ways to describe best practices, good designs, and capture experience in a way that it is possible for others to reuse this experience. The Hillside Group takes pleasure in sponsoring many different PLoP conferences that are provided for the betterment of the pattern community.
Fundamental to any science or engineering discipline is a common vocabulary for expressing its concepts, and a language for relating them together. The goal of patterns within the software community is to create a body of literature to help software developers resolve recurring problems encountered throughout all of software development. Patterns help create a shared language for communicating insight and experience about these problems and their solutions. Formally codifying these solutions and their relationships lets us successfully capture the body of knowledge which defines our understanding of good architectures that meet the needs of their users. Forming a common pattern language for conveying the structures and mechanisms of our architectures allows us to intelligibly reason about them. The primary focus is not so much on technology as it is on creating a culture to document and support sound engineering architecture and design.

Security Patterns in Practice
Eduardo Fernandez's new book " Security Patterns in Practice: Designing Secure Architectures with Software Patterns " has been published.
It is the result of 14 years of producing security patterns with students and colleagues. Almost all of these patterns went through PLoP, EuroPLoP, AsianPLoP, or SugarLoafPLoP. Many of you have participated as shepherds or workshop commentators, the book owes something to
