    1. This is a very dangerous practice as each optimization means making assumptions. If you are compressing an image you make an assumption that some payload can be cut out without seriously affecting the quality, if you are adding a cache to your backend you assume that the API will return same results. A correct assumption allows you to spare resources. A false assumption introduces a bug in your app. That’s why optimizations should be done consciously.

    1. Yup, three years later, I have the exact same problem still with my otherwise great Surface Book 1. This has made me distrust Microsoft hardware, and yes, windows machines as a whole. Especially as my previous Dell laptop was also unreliable in this regard. Such a shame, because otherwise it's a fantastic piece of kit.

    1. Frictionial sliding refers to the movement on a preexisting surface when shear surface exceeds sliding resistance.

      Frictional force is function of normal force. Frictional force is independent of the area of contact and independent of material used- weight of the block is dependent. whys is that?

      There is roughness to every surface which anchor the surface in the asperities. ifthe block is heavier ore areas will touch and increase how anchored the object is to the surface.

      A scaled up pool ball has higher topographical area than our own planet does if pool ball was size of earth.

      Table with legs on carpet= contact points sliding along a surface
