Common bugs in writing (2021)
Like almost all rules, there are cases where breaking them is a good idea and seasoned writers may well object with "but" responses for some of these. Thus, consider the rules below as mental rumble strips - you should probably slow down and think if you encounter these cases.

The faker's guide to reading x86 assembly language
Assembly code scares people. There’s a good reason for that. For many people, writing code in assembly language seems equivalent to writing code in ancient dwarven runes, or calculating pi in roman numerals. The fact that RollerCoaster Tycoon was almost completely written in assembly language sounds almost too amazing…

The New XOR Problem
In 1969, Marvin Minsky and Seymour Papert published Perceptrons: An Introduction to Computational Geometry. In it, they showed that a single-layer perceptron cannot compute the XOR function.
