  • Ventilation | CDC

    This is significant — the CDC is _finally_ detailing mitigation strategies against airborne SARS-CoV-2.

    When indoors, ventilation mitigation strategies help to offset the absence of natural wind and reduce the concentration of viral particles in the indoor air. The lower the concentration, the less likely some of those viral particles can be inhaled into your lungs; contact your eyes, nose, and mouth; or fall out of the air to accumulate on surfaces. Protective ventilation practices and interventions can reduce the airborne concentration, which reduces the overall viral dose to occupants. Below is a list of ventilation interventions that can help reduce the concentration of virus particles in the air, such as SARS-CoV-2. They represent a list of “tools in the mitigation toolbox,” each of which can be effective on their own.  Implementing multiple tools at the same time is consistent with CDC mitigation strategies and increases overall effectiveness. These ventilation interventions can reduce the risk of exposure to the virus and reduce the spread of disease, but they will not eliminate risk completely.

  • dropbox/setsum

    Via Robert Escriva – ‘the set-based checksum algorithm we made. Add items in any order and still get the same checksum. Union two independently created sets and get the same result as having done it as one iteration.’
