  • You’re mixing up the Fermi paradox and the Drake equation.

    Assuming you meant the Drake equation, more than half of the variables we have absolutely no statistical basis to decide on a fraction. Obviously they are non-zero, but they could be extremely improbable. We only have one example of intelligent life developing radio communications. Any estimate of a statistical likelihood of that using Earth as an example is meaningless without other examples.

    Some pessimistic estimates give solutions as small 9.1 x 10^-13 which indicates we would be alone.

    The Fermi Paradox riffs on the optimistic answer to Drake’s Equation. If other intelligent life is a certainty, why haven’t we found them yet?




  • I finally overhauled my home server. I built a 12TB storage and media server using a few parts from the old server but am running it on Linux using docker rather than my old gaming PC’s windows 7 install. Should be much better for security and easier to upgrade or move.

    Paid for PlexPass finally since hardware transcoding is locked behind the paywall.

    Dropped Netflix after over a decade of using it regularly because the prices went up and I had been using it less.

    Have used ChatGPT for help planning trips and developing goals and plans at home. I was restricted from using it or anything like it at work so I haven’t been able to properly use it to my advantage much.

    Finally upgraded my router to WiFi 6 and my Internet bandwidth to gigabit from 250 mbps. It’s refreshing! Probably the best decision I made in 2023.

    Dropped reddit (to include blocking the domain on my pihole). I still waste time but less of it is on social media.


  • Inspection intervals are based on expectation of damage over time, not to verify if the installation procedure was properly followed.

    Design requirements for airplane parts that experience rotation or are part of control systems are regulated to have locking features to prevent loose bolts from happening. If the initial installation was done improperly it could be a failure in quality control at Boeing. Or if they were installed properly but weren’t designed with sufficient locking mechanisms it may be an improper design. Either way this could turn into an Airworthiness Directive which is when the FAA steps in to ensure safety.








  • Everyone should learn the basics of troubleshooting!

    When trying to resolve a problem it’s really important to keep as many variables under control as possible so that you can find the root cause and fix it.

    I see lots of people who try a bunch of things without isolating the issue first but can’t figure out what is wrong. Then because they messed with it so much it’s almost impossible to figure out.

    This is important for car maintenance, home maintenance, electronics, computers. Just about everything that can break or stop working right in your life.






  • It is undefined because the inverse of division is multiplication. If you multiply by zero, every answer is zero. If you try to invert that operation you can’t know which number was multiplied by zero to get zero because multiplying by zero doesn’t produce a unique answer for each operation.

    Additionally, if you take the limit of 1/x as x approaches zero from the positive side the result approaches positive infinity. If you take the limit from the negative side it approaches negative infinity.

    An interesting thing to think about is whether multiplication by zero really makes much sense in the concrete world. You can’t really have zero groups of something or some number of groups of zero. Zero groups of anything is still nothing. We can think of that abstractly once we have the abstract concept of numbers, but in the real world that idea is nonsense.
