  • Sunshine is a host application on your computer that replaces the Nvidia Shield streaming app. Since Nvidia removed that function from the current builds of the Nvidia app you can use Sunshine instead. It also works for Intel and AMD GPUs.

    Once you have Sunshine installed and synced with your steam deck you can add any application to Sunshine to allow streaming. In the Xbox PC app find your game executeable location by going to the game page you want to add, then go to More Actions menu>Manage>Files>Browse>Game Folder>Content folder. Add an Application to Sunshine by going to the Applications tab and +Add New. Copy the path of the executeable to the Command field and type in the name of the App. That’s the minimum required to run it, but you can also add boxart. Usually it can find it automatically though which is nice.



  • The SR-71 used an Astroinertial Navigation System that used stars to keep the navigation information accurate as the plane flew over long distances. Normally an inertial navigation system degrades in accuracy over time and distance due to small errors building up and something called gyro drift. The NAS-14V2 used a catalog of known stars and a gimballed telescope to identify specific stars (even during a cloudy day) and determine the position of the stars in relation to the aircraft. Using this information the position of the aircraft can be used to revise the inertial navigation system’s data every so often so the accuracy is much better.










  • 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.
