Fourth Workshop on Computing within Limits
May 13-14, Toronto, Canada

About ACM LIMITS 2018

The ACM LIMITS workshop aims to foster discussion on the impact of present and future ecological, material, energetic, and societal limits on computing. These topics are seldom discussed in contemporary computing research. A key aim of the workshop is to promote innovative, concrete research, potentially of an interdisciplinary nature, that focuses on technologies, critiques, techniques, and contexts for computing within fundamental economic and ecological limits. A longer-term goal is to build a community around relevant topics and research. We hope to impact society through the design and development of computing systems in the abundant present for use in a future of limits. This year we are colocating for the first time with ICT4S.

Call For Papers

The submission site is now open for submissions; see below for details.

LIMITS aims to foster research on the impact of present or future ecological, material, energetic, and/or societal limits on computing and computing research to respond to such limits. The medium-term aim of the workshop is to foster concrete research, potentially of an interdisciplinary nature, that innovates on technologies, techniques, and contexts for computing within fundamental limits. A longer-term goal is to build a community around relevant topics and research. A goal of this community is to impact society through the design and development of computing systems in the abundant present for use in a future of limits and/or scarcity.

We envision two broad categories of papers: "discussion papers" and "systems papers" (see below). Submissions do not need to strictly fit into either category. All papers should succinctly frame the limits that are of interest to the author(s).

Discussion papers explore the nature of limits and computing. Good discussion contributions will detail the nature of the limits of interest, describe their impact on computing, and present directions for future research. Relevant topics include, but are not limited to:

  • Sustainability and computing
  • Re-evaluation of conventional computing premises (e.g. Moore's law)
  • Discussion of new limits and their implications for computing
  • Analysis of unnecessary computing
  • Analysis of greenwashing in computing
  • Ecological economics and/or biophysical economics and computing
  • Implications of limits for computing systems for health, education, agriculture, transportation, entertainment, commerce, etc.

Systems papers describe the design, implementation, and evaluation of computing systems that work within or help cope with limits. Also of interest are evaluations of systems that fail due to limits. Good systems contributions will address problems that meet present or future societal needs, describe clear limits and operational boundaries, and provide a detailed evaluation of the system in question. Relevant topics include, but are not limited to:

  • Material- and manufacturing-constrained computing devices
  • Energy- and material-efficient computing and communication
  • Wide-area communication under constraints
  • Human-Computer Interaction (HCI) and Interaction Design under constraints
  • Evaluation of limits to modern computing systems
  • Life-cycle analysis of computing systems under limits
  • Computer architecture for constrained computing
  • Systems for health, education, agriculture, transportation, entertainment, commerce, etc. under limits

Program and Papers

Keynote Speakers:

Peter Victor - York University

Peter Victor, author of Managing without Growth. Slower by Design, not Disaster, is a Professor emeritus in Environmental Studies at York University. He has worked for nearly 50 years in Canada and abroad on economy and environment issues as an academic, consultant and public servant. His work on ecological economics has been recognized through the award of the Molson Prize in the Social Sciences by the Canada Council for the Arts in 2011, the Boulding Memorial Prize from the International Society for Ecological Economics in 2014, and his election to the Royal Society of Canada in 2015. Peter was the founding president of the Canadian Society of Ecological Economics and is a past-president of the Royal Canadian Institute for the Advancement of Science. Prior to becoming Dean of the Faculty of Environmental Studies at York University in 1996 he was Assistant Deputy Minister for the Environmental Science and Standards Division in the Ontario Ministry of the Environment. Currently Peter is a member of the Honorary Board of the David Suzuki Foundation and the Board of the Centre for the Advancement of a Steady State Economy, as well as belonging to several advisory boards in the public and private sectors.

Alan Borning - University of Washington

Alan Borning is Professor Emeritus in the Department of Computer Science & Engineering at the University of Washington (although retirement has not yet been entirely successful). His research interests have been in human-computer interaction, value sensitive design, and in object-oriented and constraint programming languages. In addition to work on SEED, some example projects include the UrbanSim urban simulation system; OneBusAway, a set of tools that provide real-time transit information; the Living Voters Guide, an experiment in social media and civic engagement; and a series of constraint-based programming languages and systems. He received a BA from Reed College in 1971, and a PhD in computer science from Stanford University in 1979, co-advised by Alan Kay and Terry Winograd. Awards include a Fulbright Senior Scholar Award for lecturing and research in Australia, and being named a Fellow of the Association for Computing Machinery in 2001.

Papers: TBD

Travel and Registration Overview

Travel details TBD.

There will be a registration fee of $150 non-students and $50 for students, with a $35 discount for members of ACM SIGCAS.

We have some (limited) funds to offset some/all of the travel expenses for students and other attendees. If you would like to be considered for a travel grant, please email Bonnie Nardi ( by March 30, with a brief summary of your likely travel expenses, and a brief statement of need ("I am a graduate student without external funding", etc.). We will notify all applicants of the outcome shortly thereafter.
