    Pretty cold. Discoveries I made this morning:

    EVA rubber boots are no longer flexible and difficult to wear until your feet warm them up.

    LCD displays stop working.

    The fancy microcontroller thermometer had an integer overflow and showed +64°C when it was... I guess -31 or 32? 😆

    The -25°C winter wiper fluid is now solid, but it shouldn't damage the cars as it has contracted rather than expanded like water does.

    The barn cat is still alive and got warm water and leftover porridge.

    LRT reports -34°C in nearby Ukmergė and that diesel engines can't run on jelly. Apparently LPG vehicles had problems too, not enough Propane in the mix: https://www.lrt.lt/en/news-in-english/19/2825089/lithuania-records-lowest-temperatures-in-30-years-cold-disrupts-public-transport

      Having had coffee, the thermometer overflow puzzles me. From my faintly remembered assembler days, shouldn't it overflow either -31 to +32 or -63 to +64.

      Perhaps it was just a malfunctioning outside sensor that sent its maximum value rather than a signed int wrapping around 🤷

        @yngmar If I remember correctly, LPG (as Autogas) is supposed the be a 60:40 mixture of butane and propane in the summer and the opposite ratio in winter. Although I'm not sure that is suitable down to -34°C.
