  • Children of a Dead Earth is a tactical space game with n-body Newtonian physics. This means that on the surface it is very similar to something like KSP, you can do things like orbit a Lagrange point. In addition, you can design all the parts of you spacecraft and weaponry down to the materials they use. If you can make a fuel tank made out of aerogel work with the laws of physics, then you can use it. For example, I made a coilgun that fires nukes which was devastating at close range but the low velocity of the nukes made them easy to dodge at long range and without any thrusters, they cannot course correct.

    This is not a proof as you start with the answer, albeit disguised as a known truth. Here is a real proof. Start by assigning the recurring decimal a variable.

    x = 0.9999...
    

    Now calculate 10 times this by shifting the decimal place.

    10x = 9.9999...
    

    You can then subtract the second equation from the first. Note that all the digits after the decimal cancel out, leaving us with the following.

    9x = 9
    x = 1
    

    Therefore, 0.9999… = 1. Infinity does weird things!







  • OpenFOAM. I needed powerful software to do CFD that was free, as in free beer, and found OpenFOAM. To run it on windows, the installation instructions first step was install linux on a vm then follow the linux installation instructions. I did that and started using the vm for other stuff until I found myself using the vm for most tasks, but kept using windows for gaming. To learn more, I got myself a pinebook, which replaced most of the usage of my vm. When windows decided to self destruct, I had learnt enough to install and configure arch with minimal help. Now, nothing can persuade me to go back.
