The yield curve has un-inverted
I haven't followed this in a while, I don't have alerts set up for this - but as a reminder, the yield curve has un-inverted, and has stayed uninverted for some days. We usually see "official" "recessions" when this happens: not when the yield curve inverts, but when it uninverts, or shortly after.

Softmax
- This algorithm ensures that weights are non-negative,
- and that they sum up to 1.
- It's a normalization algorithm

Blabbering on tv is not the same thing as running a society. In fact, politicians don't "run the society", industrialists and operators run it. Lumberjacks run the society.
Running a society is hard work, men's work! If a woman wants to run a society, she needs to grow a pair of balls, and then "free time" will be a thing of distant dreams. WTF is "free time" anyway? My time is not free.
To scale this up to generate a single watt would cost $10.5B and weigh 15 tons.
Because the spacecraft was designed to travel far from the Sun where solar panels are useless, it required a nuclear power source.
Key Features of the Power System
The Fuel: The system uses Plutonium-238 in the form of plutonium oxide.
Heat to Electricity: The natural radioactive decay of the plutonium generates heat. Thermocouples then convert this thermal energy directly into electricity.
The Units: Voyager 1 carries three RTGs, which are mounted together on a long boom to keep radiation away from the sensitive science instruments.
Initial Output: At launch in 1977, the three RTGs combined produced about 470 watts of power.
Current Power Status: due to the radioactive half-life of the plutonium and the degradation of the thermocouples. The power output decreases by about 4 watts every year
