Instead of perturbing each pixel in the input image at random, we can choose to dither by a predetermined amount depending on the pixel’s position in the image. This can be achieved using a threshold map; a small, fixed-size matrix where each entry tells us the amount by which to perturb the input value , producing the dithered value . This matrix is tiled across the input image and sampled for every pixel during the dithering process. The following describes a dithering function for a 4×4 matrix given the pixel raster coordinates :
BuildKit is a general-purpose, pluggable build framework. It can produce OCI images, yes, but also tarballs, local directories, APK packages, RPMs, or anything else you can describe as a directed acyclic graph of filesystem operations. The Dockerfile is just one frontend. You can write your own.
，这一点在91视频中也有详细论述
同时，平台化调度降低了获客难度。过去做设备租赁需要自己跑客户、维护关系，现在通过平台撮合订单，看上去效率更高。这也是“普通人可入局”的逻辑支点。
