Why Programming Books Fail: They Never Explain HOW It Works

Assembly Arithmetic Algorithms 32 and 64 bit Windows Edition by Chastity White Rose

Assembly programming is actually a lot like Minecraft or Terraria because you start the game with nothing and have to slowly build your tools to make something useful. I started Assembly in 2024 and have already built a series of tools I personally use on both DOS and Linux operating systems. Through the course of this book, I will be slowly showing you how I can port everything in the Linux version of Assembly Arithmetic Algorithms to Windows.

Friend Pays 5x Price After Seeing Link — No Coupon Needed!

No Direction by Max Guernsey, III

It's 1021 AD, and a supernatural organization that makes kings kneel has sent three ancient and powerful Hunters after a renegade searching for technology from a civilization that vanished long ago. Their quarry is so weak he is nearly mortal, and he should have been caught almost immediately. Instead, he chooses when they meet, chooses the ground, and turns every apparent advantage against them. As the chase carries the Hunters farther from the Council's power, they begin to realize that they may be pursuing him, but he controls the Hunt. And all the while, he is getting closer to technology they cannot afford to let him find.
