  • I’m not sure I’d trust modern CA to do Med3 justice. The new style of Total War is just a different beast from the sublime RTW/Med2 era.

    Lots of little things changed, and it just ‘hits different’. Probably the biggest difference is just that every single fight after the first 20 turns will be a 20 stack vs a 20 stack, and every single battle is life or death for that army. It makes the campaign much faster paced - declare war, wipe stack, capture cities for 3 turns until the AI magics up another 20 stack.

    In the original Med2, since there wasn’t automatic replenishment, there were often battles between smaller stacks, even in late game, as they were sent from the backline to reinforce the large armies on the front. Led to some of my greatest memories trying to keep some random crossbowmen and cavalry alive against some ambushing enemy infantry they wandered into. The need for manual reinforcement led to natural pauses in wars and gave the losing side a chance to regroup without relying on the insane AI bonuses of the modern TW games - and I do mean insane; they’ll have multiple full stacks supplied from a single settlement.








  • Victoria 3 was just boring - I say this as a huge fan of Victoria 2.

    I played a few weeks after launch, and - for every one of the 4 countries I tried (Russia, Japan, Denmark, Spain), simply building all the things everywhere and ignoring money made everything trivial.

    The economic simulation was super barebones, the entire thing could be bootstrapped just by building. An entire population of illiterate farmers would become master architects overnight and send GDP to the double digit billions in a few decades.





  • With refresh rates like that, you must be talking about LED billboards.

    These are different from consumer monitors, which mostly use constant LED backlights and a liquid crystal layer to determine color.

    An LED bilboard is going to have a fuckton of singular LEDs - each of which can emit exactly one color - arranged in groups to form full pixels capable of displaying many colors. There is no extra LCD layer between your eyes and the billboard LEDs.

    The reason for the high refresh rates is because each led must be extinguished and and relit to redraw the image, and the eye is very good at picking up this strobe effect.

    The difference vs. a consumer display is that the backlight in a typical monitor is constant. Refreshes the screen involves sending updated instructions to the LCD layer, twisting the crystals and possibly changing the color they allow through.

    To make a crude concrete example:

    Imagine I am shining a white flashlight in your face. In front of the flashlight I put a colored piece of plastic so the light hitting you is colored. Then I change the plastic to one with a (slightly) different color. I do this 120 times per second. That is a typical consumer display.

    Now imagine I am shining a colored flashlight directly in your face. Then I turn it off and grab a flashlight of a different color and shine it in your face. Imagine I do that 120 times per second. That is an LED billboard.

    Which do you think is more likely to give you a headache?

    One final complication - the brightness of the LEDs is variable over time, they received a modulated signal rather than a steady voltage, so at lower refresh rates there will be a noticeable ripple across the image, similar to how early CRT screens could look.

    Increasing the refresh rate hides a lot of these problems.




  • it’s not spontaneous

    Spontaneity in thermodynamics refers to a process which occurs without external application of energy. In your description, a pile of ash becoming an apple is spontaneous.

    So in a contained universe, it doesn’t matter if it’s an apple releasing energy and becoming a pile of ash, or a pile of ash absorbing energy and becoming a perfectly normal apple.

    The net energy is still conserved. Just going from energy to mass unlike mass to energy.

    There is no mass-energy conversion in an apple burning to become ash, just the release of chemical energy from newly-formed bonds.

    Regardless, conservation of energy is only one part of how the universe operates. The second operating principle is (or at least from hundreds of years of scientific inquiry appears to be) the maximization of entropy. That is the ‘spreading out’ of available energy. This is the reason iron rusts, rather than remaining oxygen and iron - conservation of energy alone cannot explain natural phenomena.

    Spontaneous reconstruction of an ashed apple violates the second law of thermodynamics, and the Second law is no less valid than the First.

    Lastly, I was not writing specifically about Penrose’s views on consciousness. His entire theory that gravity is driving the collapse of a wave function, and that said collapse occurs retroactively, is untested and based on an appeal to elegance. This does not make it wrong, but it most certainly should not be taken as true.




  • Explaining what happens in a neural net is trivial. All they do is approximate (generally) nonlinear functions with a long series of multiplications and some rectification operations.

    That isn’t the hard part, you can track all of the math at each step.

    The hard part is stating a simple explanation for the semantic meaning of each operation.

    When a human solves a problem, we like to think that it occurs in discrete steps with simple goals: “First I will draw a diagram and put in the known information, then I will write the governing equations, then simplify them for the physics of the problem”, and so on.

    Neural nets don’t appear to solve problems that way, each atomic operation does not have that semantic meaning. That is the root of all the reporting about how they are such ‘black boxes’ and researchers ‘don’t understand’ how they work.
