You may have heard about Windows RT vs Windows 8. They’re, like, almost the same, but also really different? It’s confusing. Well, here’s the difference:
Windows 8 can only run on x86/x64 processors. Windows RT can only run on ARM processors.
Cool. But why does x86/x64 vs ARM matter? Why does each processor require different versions of Windows?… Read the rest
“Dang Ben,” you say, “it’s absurd how good you are at Starcraft 2!” Well, yeah, you’re right. But what’s almost as absurd is how cool assembly is.
Assembly is the code that your C/C++ gets compiled to (other languages too, but fuck ’em). It’s a super low-level, close-to-the-metal language, where each line of code represents exactly one task for the processor.… Read the rest
“Hey Ben Walker”, you say, “you’re really good looking, but can you explain how my computer’s processor works?”. Well, I’m double trouble, and by the end of this post, you’re gonna understand processor architecture.
Actually, you’re gonna understand single-core scalar (as opposed to superscalar) processor architecture. These processors went obsolete in, like, 1993. So you’ll be twenty years out of date. … Read the rest

(It does require some memorization though)
So, I figured out this technique – probably somebody else figured it out before me, but I’ve never heard of it before – that reduces the task of multiplying any two numbers together into some addition, some subtraction, and one division by two.… Read the rest
