• How to set default opening folder for Nautilus file manager

    Posted in Developing Software on Mar 19, 2021

    There are several answers given to this question at AskUbuntu.com. What worked for me was the simplest of them, and what I did was one step simpler than what was given. So here's what works for me using PopOs 20 (which is just Ubuntu 20 with some elegant UI, drivers, and useability improvements). The other answers to this question give insight on what's happening and why, but this answer worked great:

    1. Copy the global launcher to the local location:

    cp /usr/share/applications/org.gnome.Nautilus.desktop /home/<YOURUSERNAME>/.local/share/applications/

    1. Make the copy executable:

    chmod +x /home/...

    A confusing thing about imaginary numbers happens when they are accidentally conflated with reals as if they are somehow on the same line. In truth, if we imagine imaginary numbers the same way we imagine reals, there is only a single point where the imaginary line and the real line coincide -- the origin, where both are at 0. All other points along these two lines are orthogonal, and thus never meet.

    While we can describe a point at 2i, it's a point which is not on the real line nor the imaginary line, but exists somewhere in the plane that stretches between these two orthogonal worlds. Alth...

  • The famous Expert comedy sketch illustrates the scapegoat mechanism in play

    Posted in Phlosphy Stuff on Mar 02, 2021

    If you have not already seen the famous 'Expert' comedy sketch, you're in for a treat. It's had 26 million views so far, so maybe you already know it.

    The sketch illustrates in a very funny way how badly an expert can be treated by a team of non-experts who all depend on his expert knowledge, but argue with him and tell him he must be wrong time after time. Basically, he's the expert... and yet nobody listens to him.

    It gets funnier as it continues because the viewer can obviously see that everything he says is perfectly reasonable, yet nothing he says or does is acceptible to the others, and ...

  • A binary mindset is actually a single-minded sort of thing

    Posted in Mathy Stuff, Phlosphy Stuff, Postinfinity Tergiversation on Feb 08, 2021

    It occurred to me the other day that one of the obstacles to people understanding how binary logic penetrates into every aspect of their lives, and how this pervasiveness causes all kinds of problems they cannot see -- just like fish cannot see water -- is the fact that binary logic manifests in day-to-day life as a sort of single-mindedness. Yes, the double-mindedness is there, under the surface, but the single-mindedness is even moreso. How it can be seen is best captured by this well-known quote from F. Scott Fitzgerald:

    "The test of a first-rate intelligence is the ability to hold two opp...

  • Yes, hyperbolic geometry does describe the inside of a sphere

    Posted in Mathy Stuff, Postinfinity Tergiversation on Feb 01, 2021

    I tried for years to get a clear intuitive image for the inside of a sphere, as clear as I already have for the outside of a sphere. It's really hard! I've even been inside a large spherical room (there's a church in Boston with one), and of course, as we all do, I can easily imagine being inside of a cubical room. But it's hard to imagine being inside a sphere, for some reason.

    When I imagine a normal sphere (from the outside), it appears suddenly in my imagination, and I'm able to zoom in or out, color it any color, make it pear-shaped, basically manipulate it in any way while comparing it t...

  • Local sovereignty ontologically precedes infinities of counting

    Posted in Mathy Stuff, Phlosphy Stuff, Postinfinity Tergiversation on Dec 06, 2020

    Before you can understand the physics of mathematical infinity properly you will need to understand the role of local sovereignty in the act of counting. The fundamental structure of infinity is not defined by layers and layers of division-of-divisions which grow larger in quantity but smaller in substance (for example, counting the number of atoms in the universe leads to unfathomably huge numbers, while the size of each unit is equally unfathomably small, and counting the quarks makes the gap even larger, etc.). Instead, it is defined at a primordial level by the requirements needed to susta...

  • An "infinite number of infinitely transparent absolute actualities"

    Posted in Mathy Stuff on May 03, 2020

    I was going to call this "Monotonic monads of infinitely superimposed zeros: Inquiries into categorical atomism at the foundation of mathematics" but I think I'll wait a moment before giving this a public title, and go with this working draft, which auto-save calls it "draft 62023" for some reason or another.

    Soon after writing those words, I discovered the phrase "infinite number of infinitely transparent absolute actualities" in a paragraph written by D. G. Leahy. It so precisely conforms in meaning with the heart of the sentence I had just written, I came back to this page.

     

     

  • The Categorical Moral Imperative of the Dunning-Kruger Effect

    Posted in Everything, Phlosphy Stuff on Mar 04, 2020

    I finally found a way to convey an elusive degree of intelligence which is primarily compassionate, an idea which I long contemplated, but could never put into words as well as I can now, thanks to an insight buried in the Dunning-Kruger effect which few people are seeing. When I first encountered mention of the Dunning-Kruger effect, it was a curious new statistically-driven point noted in a few obscure science discussions. Shortly thereafter, I saw my smart, snarkier friends begin posting references to it on social media. As far as I could tell, all of them posted it with an implied, self-ri...

  • Another way of seeing is embedded in how you see now

    Posted in Developing Software, Everything on Mar 04, 2020

    A story I once heard, but a quick search didn't turn up details, so if others have more information, let me know in the comments: Somewhere in the 70s there was a drive to develop software for Air Traffic Controllers to use. The first iteration of the software was an abysmal failure. The second iteration, done more carefully with lessons learned, was also an abysmal failure. So the third time around, the software architects recruited air traffic controllers to learn how to write software, and taught them how to code. This team created a system that worked, and worked well for decades.
