Malleable software: Restoring user agency in a world of locked-down apps

The original promise of personal computing was a new kind of clay. Instead, we got appliances: built far away, sealed, unchangeable. In this essay, we envision malleable software: tools that users can reshape with minimal friction to suit their unique needs.

Perfect Software - Software for an Audience of One

We have many names to describe personal tools. Malleable software speaks to how it behaves. Home-cooked software speaks to who makes it.

Geoffrey Litt

Welcome! I work on malleable software: computing environments where anyone can adapt their software to meet their needs with minimal friction. To see what that means to me, read this essay or listen to this interview.

Ink & Switch malleable software essay

When I program, I personally prefer to be controlled by the tools I use. They were build for a reason, for a specific workflow. I want my program to typecheck. I dont want to have the freedom to write untyped programs. I don’t want git to also have the ability to crop images. At this specific moment, I want to perform a specific task and I want the tools to help me do it, nothing more complex , or annoying , that could allow me to shoot myself to the foot. Control is bliss. Control is bliss as ...

Designing and Programming Malleable Software

User needs for software features and interfaces are diverse and changing, motivating the goal of making it as easy as possible for users themselves to change software, or to have it changed on their behalf in response to their developing needs. However, in my opinion, current approaches do not address this issue adequately: software engineering promotes flexible code, but in practice this does not help end-users effect change in their software. End-user and live programming systems help users customize their interfaces by accessing and modifying the underlying source code. I take a different approach, seeking to maximize the kinds of modifications that can take place through regular interactions, e.g. direct manipulation of interface elements. I call this approach malleable software. To understand contemporary needs for and barriers to modifying software, I study how it is produced, maintained, adopted, and appropriated in a network of communities working with biodiversity data. I find that the mode of software production, i.e. the technologies and economic relations that produce software, is biased towards centralized, one-size-fits-all systems. This leads me to propose a long-term, interdisciplinary research program in reforming the tools of software development to create infrastructures for plurality. These tools should help multiple communities collaborate without forcing them to consolidate around identical interfaces or data representations. Malleable software is one such infrastructure, in which interactive systems are dynamic constellations of interfaces, devices, and programs assembled at the site of use. My technological contribution is a reconstruction of the programming mechanisms used to create interactive behavior. I generalize existing control structures for interaction as entanglements, and develop a higher-order control structure, entanglers, which produces entanglements when particular pre-conditions, called co-occurrences, are met. Entanglers cause interactions to be assembled dynamically as system components come and go. I develop these mechanisms in Tangler, a prototype environment for building malleable interactive software. I demonstrate how Tangler supports malleability through a set of benchmark cases illustrating how users can modify systems by themselves or with programmer assistance. This thesis is an early step towards a paradigm for programming and designing malleable software that can keep up with human diversity.

Between Principle and Pragmatism: Reflections on Prototyping Computational Media with Webstrates

Computational media describes a vision of software, which, in contrast to application-centric software, is (1) malleable, so users can modify existing functionality, (2) computable, so users can run custom code, (3) distributable, so users can open documents across different devices, and (4) shareable, so users can easily share and collaborate on documents. Over the last ten years, the Webstrates and Codestrates projects aimed at realizing this vision of computational media. Webstrates is a server application that synchronizes the DOM of websites. Codestrates builds on top of Webstrates and adds an authoring environment, which blurs the use and development of applications. Grounded in a chronology of the development of Webstrates and Codestrates, we present eight tensions that we needed to balance during their development. We use these tensions as an analytical lens in three case studies and a game challenge in which participants created games using Codestrates. We discuss the results of the game challenge based on these tensions and present key takeaways for six of them. Finally, we present six lessons learned from our endeavor to realize the vision of computational media, demonstrating the balancing act of weighing the vision against the pragmatics of implementing a working system.

Malleable software in the age of LLMs

All computer users may soon have the ability to author small bits of code. What structural changes does this imply for the production and distribution of software?
