Locating sex: regional geographies of sexual social media

Contributing to the field of the geographies of digital sexualities, this article explores the geosocial dimensions of digital sexual cultures by analyzing three regionally operating, linguistically specific social media platforms devoted to sexual expression. Drawing on case studies of an Estonian platform used primarily for group sex, a Swedish platform for kink and BDSM, and a Finnish platform for nude self-expression, we ask how these contribute to and shape sexual geographies in digital and physical registers. First, we focus on the platforms as tools for digital wayfinding and hooking up. Second, we consider how the platforms help to reimagine and sexualize physical locations as ones of play, and how this transforms the ways of inhabiting such spaces. Third, we analyze how the platforms operate as sexual places in their own right, designed to accommodate certain forms of display, relating, and belonging. We argue, in particular, that these platforms shape how users imagine and engage with location by negotiating notions of proximity and distance, risk and safety, making space for sexual sociability. We approach geographies of sexuality both through the regional and linguistic boundaries within which these platforms operate, as well as through our participants’ sense of comfort and investment in local spaces of sexual play. As sexual content is increasingly pushed out of large, U.S.-owned social media platforms, we argue that locally operating platforms provide a critical counterpoint, allowing for a vital re-platforming of sex on a regional level.</p

Incremental Distance Transforms (IDT)

A new generic scheme for incremental implementations of distance transforms (DT) is presented: Incremental Distance Transforms (IDT). This scheme is applied on the cityblock, Chamfer, and three recent exact Euclidean DT (E2DT). A benchmark shows that for all five DT, the incremental implementation results in a significant speedup: 3.4×−10×. However, significant differences (i.e., up to 12.5×) among the DT remain present. The FEED transform, one of the recent E2DT, even showed to be faster than both city-block and Chamfer DT. So, through a very efficient incremental processing scheme for DT, a relief is found for E2DT’s computational burden
