Protester operated drones are beginning to appear in the skies above protests, offering protesters new ways to watch the police. Previous work on resisting surveillance has focused upon resisting surveillance by state authorities, such as the police. This article, however, reverses this arrangement and explores the ways in which the police can attempt to resist surveillance by protesters. It explores legislation, physical and electronic efforts to minimise the effects of the gaze of the drone.

Long-term borehole temperature monitoring in mountain permafrost environments is challenging under the hostile conditions reigning there. On the basis of data measured in the SLF borehole network we show situations where ground temperature data should be interpreted with caution. A selection of recently observed problems are discussed, and advantages and possible drawbacks of various solutions including data correction, measurement redundancy or alternate instrumentation are presented.

This paper discusses the development of the market for small commercial drones in the USA. I suggest the market does not just develop by itself, but through a whole series of struggles by various people and institutions. Drones are also part of an increasing dependence by society on machine decision-making, which is replacing human decision-making. I was interested in examining these developments in the context of small drones and the possibility of new geographies of the sky.

During the last 45 years, about 100 people lost their lives in avalanches in the European Alps each year. Avalanche fatalities in settlements and on transportation corridors have considerably decreased since the 1970s. In contrast, the number of avalanche fatalities during recreational activities away from avalanche-secured terrain doubled between the 1960s and 1980s and has remained relatively stable since, despite a continuing strong increase in winter backcountry recreational activities.
