    Forget-me-not: History-less Mobile Messaging

    Text messaging has long been a popular activity, and today smartphone apps enable users to choose from a plethora of mobile messaging applications. While we know a lot about SMS practices, we know less about practices of messaging applications. In this paper, we take a first step to explore one ubiquitous aspect of mobile messaging – messaging history. We designed, built, and trialled a mobile messaging application without history—named forget-me-not. The two-week trial showed that history-less messaging no longer supports chit-chat as seen in e.g. WhatsApp, but is still considered conversational and more ‘engaging’. Participants expressed being lenient and relaxed about what they wrote. Removing the history allowed us to gain insights into what uses history has in other mobile messaging applications, such as planning events, allowing for distractions, and maintaining multiple conversation threads

    Rape Messaging

    When feminists began advocating for rape reform in the 1970s, the rape message was clear: rape was not a crime to be taken seriously because women lie. After decades of criminal law reform, the legal requirement that a woman vigorously resist a man’s sexual advances to prove that she was raped has largely disappeared from the statute books, and, in theory, rape shield laws make a woman’s prior sexual history irrelevant. Yet, despite what the law dictates, rape law reforms have not had a “trickle-down” effect, where changes in law lead to changes in attitude. Women are still believed to be vindictive shrews so police continue to code rape allegations as “unfounded,” and prosecutors continue to elect not to prosecute many rape cases. To many, “no” can sometimes still mean “yes.” In short, criminal law reforms have only marginally succeeded at deterring rape and increasing conviction rates for rape. At the same time, criminal law reforms have entrenched gender norms and endorsed the message that acquaintance rapes are less worthy of harsh punishment. This Article argues against further ex post criminal law reforms and posits that efforts should shift to ex ante public health interventions. This Article draws from recent successful experiences with public health interventions in destigmatizing AIDS and denormalizing tobacco and advocates for a robust public health campaign to denormalize rape. It presents a detailed proposal for changing rape messaging, denormalizing rape, and ensuring better outcomes for victims

    IVOA Recommendation: SAMP - Simple Application Messaging Protocol Version 1.3

    SAMP is a messaging protocol that enables astronomy software tools to interoperate and communicate. IVOA members have recognised that building a monolithic tool that attempts to fulfil all the requirements of all users is impractical, and it is a better use of our limited resources to enable individual tools to work together better. One element of this is defining common file formats for the exchange of data between different applications. Another important component is a messaging system that enables the applications to share data and take advantage of each other's functionality. SAMP builds on the success of a prior messaging protocol, PLASTIC, which has been in use since 2006 in over a dozen astronomy applications and has proven popular with users and developers. It is also intended to form a framework for more general messaging requirements

    The Lifecycle and Cascade of WeChat Social Messaging Groups

    Social instant messaging services are emerging as a transformative form with which people connect, communicate with friends in their daily life - they catalyze the formation of social groups, and they bring people stronger sense of community and connection. However, research community still knows little about the formation and evolution of groups in the context of social messaging - their lifecycles, the change in their underlying structures over time, and the diffusion processes by which they develop new members. In this paper, we analyze the daily usage logs from WeChat group messaging platform - the largest standalone messaging communication service in China - with the goal of understanding the processes by which social messaging groups come together, grow new members, and evolve over time. Specifically, we discover a strong dichotomy among groups in terms of their lifecycle, and develop a separability model by taking into account a broad range of group-level features, showing that long-term and short-term groups are inherently distinct. We also found that the lifecycle of messaging groups is largely dependent on their social roles and functions in users' daily social experiences and specific purposes. Given the strong separability between the long-term and short-term groups, we further address the problem concerning the early prediction of successful communities. In addition to modeling the growth and evolution from group-level perspective, we investigate the individual-level attributes of group members and study the diffusion process by which groups gain new members. By considering members' historical engagement behavior as well as the local social network structure that they embedded in, we develop a membership cascade model and demonstrate the effectiveness by achieving AUC of 95.31% in predicting inviter, and an AUC of 98.66% in predicting invitee.Comment: 10 pages, 8 figures, to appear in proceedings of the 25th International World Wide Web Conference (WWW 2016

    A Configurable Transport Layer for CAF

    Full text link
    The message-driven nature of actors lays a foundation for developing scalable and distributed software. While the actor itself has been thoroughly modeled, the message passing layer lacks a common definition. Properties and guarantees of message exchange often shift with implementations and contexts. This adds complexity to the development process, limits portability, and removes transparency from distributed actor systems. In this work, we examine actor communication, focusing on the implementation and runtime costs of reliable and ordered delivery. Both guarantees are often based on TCP for remote messaging, which mixes network transport with the semantics of messaging. However, the choice of transport may follow different constraints and is often governed by deployment. As a first step towards re-architecting actor-to-actor communication, we decouple the messaging guarantees from the transport protocol. We validate our approach by redesigning the network stack of the C++ Actor Framework (CAF) so that it allows to combine an arbitrary transport protocol with additional functions for remote messaging. An evaluation quantifies the cost of composability and the impact of individual layers on the entire stack
