YouTube tech blogger “Inkbox” recently released a video demonstrating how to build a fully functional CPU within the limitations of Microsoft Excel. Inkbox claims that no Visual Basic scripts or plugins were used—everything was achieved entirely with Excel. https://www.youtube.com/watch?v=5rg7xvTJ8SU It is reported that this is a 16-bit CPU built in Excel and runs at a … Read more
For those of us born in the 80s, our first encounter with computers likely occurred around 1995, when the buzzword was multimedia. I still remember watching a classmate successfully open a game by entering a few DOS commands, and I was utterly impressed. To me, what appeared on the screen was like a foreign language. … Read more
Do you know how the programming languages you often use are implemented? Today, let’s talk about this question. Smart humans discovered that by combining simple switches, they could express complex boolean logic. Based on this, they built the CPU, which can only understand switches in a simple way, represented numerically as 0 and 1. The … Read more

What’s the point of knowing all these details? This kind of thinking is actually… not wrong. Routers are quite similar to the computers or … Read more
This article is excerpted from “2022 Research Framework for Domestic Server CPUs“. In the post-Moore’s Law era, the performance benefits brought by the improvement of process technology are already very limited. The Dennard Scaling law constraints have led to a sharp increase in chip power consumption, and the cost of transistors has risen instead of … Read more
