Book review: the end of policing by Alex S. Vitale
Full text linkIn The End of Policing, Alex S. Vitale offers an indictment of contemporary policing in the US, condemning not only the roles and actions of the US police, but also the extensive, growing reach of crime control and criminalisation processes. While the book cannot fully realise its ambition to envisage ‘policing without the police’, this is a welcome challenge to reformist thinking and a powerful argument against social and economic injustice, inequality and racism, finds Karim Murji

Photovoltaic sample-and-hold circuit enabling MPPT indoors for low-power systems
Full text linkPhotovoltaic (PV) energy harvesting is commonly used to power autonomous devices, and maximum power point tracking (MPPT) is often used to optimize its efficiency. This paper describes an ultra low-power MPPT circuit with a novel sample-and-hold and cold-start arrangement, enabling MPPT across the range of light intensities found indoors, which has not been reported before. The circuit has been validated in practice and found to cold-start and operate from 100 lux (typical of dim indoor lighting) up to 5000 lux with a 55cm2 amorphous silicon PV module. It is more efficient than non-MPPT circuits, which are the state-of-the-art for indoor PV systems. The proposed circuit maximizes the active time of the PV module by carrying out samples only once per minute. The MPPT control arrangement draws a quiescent current draw of only 8µA, and does not require an additional light sensor as has been required by previously-reported low-power MPPT circuits
