Remote monitoring doesn’t imply remote management- one is sensible, one is a power trip. We are required to monitor our refrigeration and we did it with a distributed system of…

That is also likely true, i.e., misconfiguration, but this is not a "military freezers hacked" story, it is a story of many different controllers of many different refrigeration…

AI or not - can we agree to stop doing this now that AI has ruined it: "But the thing I can’t get past is Fort Huachuca’s failure mode. Not: the freezer compressor died. Not: th…

Nope, I'm one of those lucky folks who was privileged enough to be accused of writing in a weird and probably too mature for my high school English paper-way before the advent o…

Refrigeration is the artificial cooling of a space, substance, or system to lower and/or maintain its temperature below the ambient temperature. Early refrigeration uses consumable coolants such as ice and dry ice, while modern refrigeration is a self-sustaining heat exchanger process by which thermal energy is transferred against the temperature gradient via the use of a heat-transfer working fluid, which absorbs heat from a low-temperature medium and releases it to another higher-temperature medium, typically involving active phase change via a compressor and aided by a radiator system. Energy transfer in refrigeration is traditionally driven by physical means, but it can also be driven by heat pump, magnetism, electricity, laser cooling, or other means. Refrigeration has many applications, including household refrigerators, industrial freezers, cryogenics, and cool store air conditioning. Heat pumps may make use of the heat output of the refrigeration process, and also may be designed to be reversible, but are otherwise similar to air conditioning units. Read more on Wikipedia
