Unlock the secrets to creating random mazes! Whether you're a game developer, an algorithm connoisseur, or simply in search of a new puzzle, you're about to level up. Learn algorithms to randomly generate mazes in a variety of shapes, sizes, and dimensions. Bend them into Moebius strips, fold them into cubes, and wrap them around spheres. Stretch them into other dimensions, squeeze them into arbitrary outlines, and tile them in a dizzying variety of ways. From twelve little algorithms, you...

Brace yourself for a fun challenge: build a photorealistic 3D renderer from scratch! It's easier than you think. In just a couple of weeks, build a ray-tracer that renders beautiful scenes with shadows, reflections, brilliant refraction effects, and subjects composed of various graphics primitives: spheres, cubes, cylinders, triangles, and more. With each chapter, implement another piece of the puzzle and move the renderer that much further forward. Do all of this in whichever language and...

Cultural identity matters—to us and to Jesus.Culture is all around us. Nothing we think, do, or say exists outside of it. But the story of God is clear: We are all made in God’s good image, and God’s people are meant to be a diverse community. Looking to the example of Jesus, author J. W. Buck offers practical insights into how cultural identity fits into our walk as Christians. No matter where we come from and no matter how complex our cultural narratives, the Scr...

The classic guide to how computers work, updated with new chapters and interactive graphics"For me, Code was a revelation. It was the first book about programming that spoke to me. It started with a story, and it built up, layer by layer, analogy by analogy, until I understood not just the Code, but the System. Code is a book that is as much about Systems Thinking and abstractions as it is about code and programming. Code teaches us how many unseen layers there...

A primer on the underlying technologies that allow computer programs to work. Covers topics like computer hardware, combinatorial logic, sequential logic, computer architecture, computer anatomy, and Input/Output.Many coders are unfamiliar with the underlying technologies that make their programs run. But why should you care when your code appears to work? Because you want it to run well and not be riddled with hard-to-find bugs. You don't want to be in the news be...

Renowned pastor and bestselling author of The Prodigal Prophet Timothy Keller shares his most provocative and illuminating message yet.It is commonly thought in secular society that the Bible is one of the greatest hindrances to doing justice. Isn’t it full of regressive views? Didn’t it condone slavery? Why look to the Bible for guidance on how to have a more just society? But Timothy Keller challenges these preconceived beliefs and presents the Bible as ...

Practical and Gospel-centered thoughts on how to have a fruitful ministry by one of America's leading and most beloved pastor.Many church leaders are struggling to adapt to a culture that values individuality above loyalty to a group or institution. There have been so many "church growth" and "effective ministry" books in the past few decades that it's hard to know where to start or which ones will provide useful and honest insight.Based on over twenty year...

"This library is useful for practitioners, and is an excellent tool for those entering the field: it is a set of computer vision algorithms that work as advertised."-William T. Freeman, Computer Science and Artificial Intelligence Laboratory, Massachusetts Institute of TechnologyLearning OpenCV puts you in the middle of the rapidly expanding field of computer vision. Written by the creators of the free open source OpenCV library, this book introduces you to computer vision...

Scratch is a fun, free, beginner-friendly programming environment where you connect blocks of code to build programs. While most famously used to introduce kids to programming, Scratch can make computer science approachable for people of any age. Rather than type countless lines of code in a cryptic programming language, why not use colorful command blocks and cartoon sprites to create powerful scripts?In Learn to Program with Scratch, author Majed Marji uses Scratch to ex...

The Hardware Hacking Handbook takes you deep inside embedded devices to show how different kinds of attacks work, then guides you through each hack on real hardware.Embedded devices are chip-size microcomputers small enough to be included in the structure of the object they control, and they’re everywhere—in phones, cars, credit cards, laptops, medical equipment, even critical infrastructure. This means understanding their security is critical. The Hardware Hacking...

Overcoming Evil in the Last Days is the radical Christians handbook for uncovering and defeating the evil that pervades our culture. As the gates of hell unleash their fiendish fury against the soul of man, the Church must be prepared to defend and to attack. Joyner lifts the veil on this heartless horde, exposing the face of racism, witchcraft, and religious spirits, while making the challenge clear: maintain our warrior stance against evil as we persist in our primary calling worshi...
