  • VIX under 20 isn’t a warning… The stock market valuation indicator I agree with: stocks are a bit over valued right now. But over valued just means we need a correction… not whether it will be a mild or severe one.

    What’s more troubling is the market reacting already to nonsense trump comments. From the caption in the linked article:

    The latest market sell-off was partly triggered by former President Donald Trump’s comments on Taiwan and tariffs.

    Does no one else remember the dumpster fire that was the markets jumping at every comment and policy flip-flop during his four year term? The same volatility indicator (VIX) regularly jumped over 20 after some dumb trade policy comment…
















  • A bit of an elaboration on why water towers are used in combination with pumps. Pumps are great for moving a constant amount of water around at whatever rate the pump is designed for (e.g. a small pump will move something like 1 gallon per minute). a big enough pump (or series of smaller pumps) can cause that pumped water to consistently flow at that rate.

    The problem is that people don’t use water at a constant rate. In the morning, several residents probably all run the shower at the same time. if too many people open the water tap at the same time, a pump will give each just a fraction of what they expect.

    But a water tank high up supplies water by gravity, you could open a large number of water taps, and as long as the pipes from the tank are big enough they’d all have the same pressure as if just one opened.

    The water is gradually pumped up to the tank no matter if people are using it or not, then when many people want water, they all get it at expected pressures and the tank start to empty. Eventually people close the taps, the tank will slowly start to fill again from the pump.

    This same basic design is also how water towers supply water to many single story buildings, it’s not a unique engineering feat for skyscrapers, but an adjustment to fit somewhere within the building’s footprint.




  • If you want a fun karaoke night, first song(s) need to be something that will get most everyone singing. Younger crowds: something like Tayor Swift “Shake It Off”. Middle age crowds, something like Nirvana or Aerosmith. Older crowds any Beatles #1.

    I personally like Cyprus Hill “Jump Around” if you’re willing to learn it well enough beforehand as to not butcher the lyrics. I’ve seen Vanilla “Ice Ice Baby” also get a similar reaction of everyone knowing the song and enjoying it enough to give you kudos for choosing it.

    After everyone’s over the initial hesitation, go belt all your love songs and power ballads; but get the party started first.
