  • Postgres handles NoSQL better than many dedicated NoSQL database management systems. I kept telling another team to at least evaluate it for that purpose - but they knew better and now they are stuck with managing the MongoDB stack because they are the only ones that use it. Postgres is able to do everything they use out of the box. It just doesn’t sound as fancy and hip.




  • Extremely cheap per kilowatt? Every statistic out there that I’ve seen and that includes government funding, as well as construction and deconstruction costs, paints a different picture. Nuclear is only competitive with coal or the relatively underdeveloped solar thermal.

    In 2017 the US EIA published figures for the average levelized costs per unit of output (LCOE) for generating technologies to be brought online in 2022, as modelled for its Annual Energy Outlook. These show: advanced nuclear, 9.9 ¢/kWh; natural gas, 5.7-10.9 ¢/kWh (depending on technology); and coal with 90% carbon sequestration, 12.3 ¢/kWh (rising to 14 ¢/kWh at 30%). Among the non-dispatchable technologies, LCOE estimates vary widely: wind onshore, 5.2 ¢/kWh; solar PV, 6.7 ¢/kWh; offshore wind, 14.6 ¢/kWh; and solar thermal, 18.4 ¢/kWh.

  • Whether they are fertilized depends on the facility that produces eggs and the population of chickens at the time. Cage system housing might produce almost no fertilized eggs because the animals are isolated. That system is however outlawed in some regions of the world because of animal cruelty and the requirements of high amounts of antibiotics to counter the spread of diseases. All other systems produce at least some amount of fertilized eggs, for example because of misgendered roosters becoming part of the general population until they get spotted.

    Some people have successfully hatched some supermarket eggs and that is entirely plausible. They are not being hatched by the hens until the nest is full, so they may be laying around for many days before the hen starts sitting on them - they don’t need to be kept warm immediately.
