  • Adding little bit extra context here.

    In Finland large number of homes are heated by district heating. This means there is heat plant or combined heat and power (CHP) plant, which heats water to around 70C - 110C (158F - 230F) and that is distributed to homes.

    In this system heat batteries are useful, and near all CHP plants in Finland have done heat battery in last few years. These heat batteries are just 7-store high insulated water storage. Usefulness to store just water is that system is relatively simple. Water in - water out. This makes it that the turbine in CHP can be run more freely towards electricity price, not the network heat demand.

    Plain heat plants generally don’t yet have these, because the buffer created by heat battery is not that much needed. But if these sand batteries can store heat longer, and because they might be cheaper to build, it can make sense.

  • D365 ain’t really even that bad. It is just model driven power platform app. It is actually quite expandable, you can code it with plain javascript or more complex components on React. Backend is OData which is quite flexible.

    Old Dynamics AX and onprem CRM were shit shows.





  • Electricity network requires that production and consumption are always equal. If there is too little production, the frequency (Hz) goes down and if too little consumption, the frequency goes up. If frequency goes too far every electric device pretty much breaks.

    This is why there is automation in the network that tries to balance the network (reserve production and consumption). BUT if shit hits the fan, and frequency goes too bad, it automatically takes load off or production off the network. This often causes domino effect, you take load off, which causes over production, and again you take production off and loop is ready. In minutes the whole network falls like domino blocks, one by one.

    There was lots of luck (and probably skill and preparation) that they were able to stop it. Main land Europe from Portugal to Turkey is one big network.

    Cold starting whole Europe would have taken week. You need to start small islands, and connect them together slowly. Balancing load and production.

  • They are ultra conservative in internal politics and in public opinion, which is of course controlled by their state controlled media.

    Russia’s internal policies are wet dreams of American conservatives.

    Much of this situation is because of the Russian long running psyop campaign against American public opinion. Dividing nations is default Russian psyop playbook. They have been done that all over the world, and they are proud of it.

    You guys have clearly never had kids. It almost never goes like in the movies, you rush into hospital, and then you wait. Especially if the water broke, then you wait few days. There is absolutely nothing to do in the hospital. I would have killed for steamdeck, or even a switch.
