From math to machine: translating a function to machine code
In this post I'm going to explore how a mathematical concept can be redefined in progressively more computer-oriented terms, all the way from high level languages down to machine code, ready for direct execution by a computer. To that end, I'm going to define the same logic in several different but related formats:

Undefined Behavior != Unsafe Programming
Are you arguing that undefined behaviour should not be a thing in, e.g., C? It sounds like you’re claiming that the fabled sufficiently smart compiler could take code in a C-like language with no UB, and emit something equivalent to what a C compiler would produce given equivalent input in C that correctly avoids UB…

The Biggest and Weirdest Commits in Linux Kernel Git History
We normally think of git merges as having two parent commits. For example, the most recent Linux kernel merge as I write this is commit 2c5d955, which is part of the run-up to release 4.10-rc6. It has two parents:

50 Bytes of Code That Took 4 GB to Compile (2013)
While doing evil things with macros and the inline assembler (trying to run a weird test whose purpose is not really relevant) I managed to write a program that caused Visual Studio’s C++ compiler …

The Three Ways of XOR
We all know the XOR operation. It’s the cousin of NOT, AND and OR. Like AND and OR, it is a binary boolean function. Unlike them, most programming languages ...
