Keynote

Croquet: A Unique Collaboration Architecture
Dr. Vanessa Freudenberg
Chief Architect, Croquet Corp

The next generation of our connected world calls for a low-latency, low-bandwidth, low-development-effort platform for synchronized interactions. The platform must also enforce privacy from the ground up, in particular in anticipation of an always-on Augmented Reality future.

In traditional synchronization approaches, computations are performed on a server and results are continuously distributed to clients. Croquet moves all computation to the clients. A lightweight “reflector” server directs the clients to advance time in sync, and ensures that any external event is incorporated by all clients at exactly the same point in the computation, leading to synchronized, bit-identical state. All data is end-to-end encrypted by the clients; the server stores and distributes data, but can never peek inside.

Croquet’s programming model separates the synchronized computation of “models” from individually computed “views”. This means the world is the same for everyone, but the display of the world can be tailored to each device and user. Models and views communicate using a publish/subscribe mechanism that routes certain events via the reflector. This model/view separation and pub/sub communication is a major departure from the previous, proxy-based Smalltalk implementation of Croquet. It retains the ability for live programming by atomically incorporating new code.

Vanessa is the chief architect of the current JavaScript-based implementation. She will give an overview of the system, highlight challenges in designing the API, and explore the far-reaching implications of the shift from server to client.

Call for Papers

The 16th Dynamic Languages Symposium (DLS) at SPLASH 2020 is the premier forum for researchers and practitioners to share research and experience on all aspects on dynamic languages.

DLS 2020 invites high quality papers reporting original research and experience related to the design, implementation, and applications of dynamic languages. Areas of interest include, but are not limited to,

• innovative language features
• innovative implementation techniques
• innovative applications
• development environments and tools
• experience reports and case studies
• domain-oriented programming
• late binding, dynamic composition, and run-time adaptation
• reflection and metaprogramming
• software evolution
• language symbiosis and multi-paradigm languages
• dynamic optimization
• interpretation
• just-in-time and ahead-of-time compilation
• soft/optional/gradual typing
• hardware support
• educational approaches and perspectives
• semantics of dynamic languages
• frameworks and languages for the Cloud and the IoT

Submission Details

Submissions must neither be previously published nor under review at other events. DLS 2020 uses a lightweight double-blind, two-phase reviewing process.

Papers are assumed to be in one of the following categories:

       Research Papers:
              describe work that advances the current state of the art

       Experience Papers:
              describe insights gained from substantive practical
              applications that should be of a broad interest

       Dynamic Pearls:
              describe a known idea in an appealing way to remind the
              community and capture a reader’s interest

The program committee will evaluate each paper based on its relevance, significance, clarity, and originality. The paper category needs to be indicated during submission, and papers are judged accordingly.

Papers are to be submitted electronically in PDF format. Submissions must be in the ACM SIGPLAN conference acmart format, 10 point font, and should not exceed 12 pages. Please see full details in the instructions for authors available at:

https://conf.researchr.org/home/dls-2020#Instructions-for-Authors

DLS 2020 will run a two-phase reviewing process to help authors make their final papers the best that they can be. Accepted papers will be published in the ACM Digital Library and will be freely available for one month, starting two weeks before the event.

Important Deadlines

Abstract Submission (optional): July 2, 2020 [was: June 4]
Paper Submission: July 9, 2020 [was: June 11]
First Phase Notification: August 7, 2020
Revisions Due: September 4, 2020
Final Notifications: September 18, 2020
Camera Ready (estimated): October 10, 2020

All deadlines are 23:59 AoE (UTC-12h).

AUTHORS TAKE NOTE: The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of your conference. The official publication date affects the deadline for any patent filings related to published work.

Submitted papers need to conform to the formatting instructions. Submissions that violate these instructions may be rejected without review at the discretion of the Program Chair.

DLS 2020 uses a lightweight double-blind review process. Authors must omit their names and affiliations in their paper submissions.

Submission Site

Please take a moment to read the instructions below before using the submission site. After acceptance, the camera ready versions will be collected by Conference Publishing Consulting.

Concurrent Submissions

Papers must describe unpublished work that is not currently submitted for publication elsewhere as described by SIGPLAN’s Republication Policy. Submitters should also be aware of ACM’s Policy and Procedures on Plagiarism.

Format

Submissions should use the ACM SIGPLAN Conference acmart format, sigplan sub-format, 10 point font. All submissions should be in PDF format. If you use LaTeX or Word, please use the provided ACM SIGPLAN acmart templates. Author–year and numeric citation styles are both acceptable.

Note that by default the SIGPLAN Conference Format templates produce papers in 9 point font. If you are formatting your paper using LaTeX, you will need to set the 10pt option in the \documentclass command: \documentclass[10pt,sigplan]{acmart}. If you are formatting your paper using Word, you may wish to use the provided Word template that supports this font size.

For reviewing, please include page numbers in your submission with the LaTeX \settopmatter{printfolios=true} command.

Please also ensure that your submission is legible when printed on a black and white printer. In particular, please check that colors remain distinct and font sizes are legible.

Page Limit

To ensure that papers stay focused on their core contributions, papers are limited to 12 pages and 10pt including bibliographic references and appendices. For the second phase, the page limit is 14 pages including bibliographic references.

Second-Phase Revisions

DLS 2020 uses a two-phase review system to provide authors with extra support and an opportunity to revise submissions. The extent of revisions is limited by the available time of about 4 weeks, so the program committee will use the two-phase process only for mandatory revisions that can be completed in that time.

To facilitate reviewing, we ask the author to submit their revisions accompanied by:

• a latexdiff to the original submission, or a similarly annotated document
• as well as a high-level description of the made changes and a discussion of the points raised by the reviews

For the second phase, the page limit is 14 pages, including bibliographic references.

Publication (Digital Library Early Access Warning)

AUTHORS TAKE NOTE: The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of the conference. The official publication date affects the deadline for any patent filings related to published work.
