ONE PER CENT

摘要

It's money to burn. Looks like a warehouse in Thailand full of Bitcoin-mining machines caught fire. Local media and Bitcoin websites suggest that the facility, packed with over 2000 computers connected to the Bitcoin network, went up in flames on 7 November. Equipment worth an estimated $2 million was destroyed. The machines mined Bitcoins by solving cryptographic puzzles. The fire has been blamed for a sudden slowdown in activity on the Bitcoin network. Make yourself invisible. That's the idea behind software that removes moving objects from video imagery. The uncensored images are then only viewable when an authorised person watches the recording. Developed by Prism Skylabs, based in San Francisco, the system uses machine-learning to identify movement belonging to foreground elements, like a person walking across the camera's field of view. The software recognises the stationary background and can then paint over foreground objects to neatly hide human activity.
