特点：在特定初始化下能实现自归一化，保持激活均值和方差稳定。
Intel documentation describes the 386's Protection Test Unit as a component that "implements fast testing of complex memory protection functions." It is mostly composed of a PLA (Programmable Logic Array), referred to as Test PLA by Intel, that is physically visible by its regular appearance on the die. This single piece of combinational logic replaces what would otherwise be dozens of multi-cycle conditional branches in the microcode. Instead of testing privilege rules sequentially, the microcode issues a single protection test operation, and the PLA evaluates all applicable rules in parallel, producing a complete decision in one evaluation: continue, fault, or redirect to a gate handler.
I was confident in that approach because you would not call multiple .play()s on the same page to lead a reverse engineer astray. Why? Because mobile devices typically speaking will pause every other player except one. If fermaw were to do that, it’d ruin the experience for mobile users even if desktop users would probably be fine. It also makes casting a bitch and a half. Even if you did manage to pepper them around, it would be fairly easily to listen in on all of them and then programmatically pick out the one with actually consistent data being piped out.，更多细节参见51吃瓜
SSIM was chosen over CNN-based approaches for a deliberate reason: reproducibility without infrastructure. SSIM is a deterministic mathematical function. No training data, no model weights, no GPU, no framework dependencies. Anyone with fontconfig and node-canvas can reproduce these exact numbers on the same platform.
，这一点在91视频中也有详细论述
