  • What are Scope 3 emissions?

    I was looking for a decent definition of this over the weekend, and couldn’t find it, so bookmarking for future reference. ‘Greenhouse gas emissions are categorised into three groups or ‘Scopes’ by the most widely-used international accounting tool, the Greenhouse Gas (GHG) Protocol. Scope 1 covers direct emissions from owned or controlled sources. Scope 2 covers indirect emissions from the generation of purchased electricity, steam, heating and cooling consumed by the reporting company. Scope 3 includes all other indirect emissions that occur in a company’s value chain.’

    Looks extremely nifty — a global CDN for your code: ‘Fly is a platform for applications that need to run globally. It runs your code close to users and scales compute in cities where your app is busiest. Write your code, package it into a Docker image, deploy it to Fly’s platform and let that do all the work to keep your app snappy.’ Decent pricing, too.

  • Tetris used to prevent PTSD

    ‘Our hypothesis was that after a trauma, patients would have fewer intrusive memories [from post-traumatic stress] if they got to play Tetris as part of a short behavioural intervention while waiting in the hospital Emergency Department,’ says Professor Holmes. ‘Since the game is visually demanding, we wanted to see if it could prevent the intrusive aspects of the traumatic memories from becoming established i.e. by disrupting a process known as memory consolidation.’ The study involved 71 motor vehicle accident victims, of whom half received the intervention (recalled the trauma briefly and then played Tetris) while waiting in the hospital emergency department, and half performed another task, all doing so within six hours of the accident. Results showed that the researchers’ hypothesis was right: those who had played Tetris had fewer intrusive memories of the trauma in total over the week immediately following the accident than the controls. The researchers also found that the intrusive memories diminished more quickly.
    Amazing! The paper is at ; follow-up trials with more participants are underway.
