Proximal Algorithms by Neal Parikh, Stephen Boyd (2014) is now in @ChapterPal's collection of open textbooks. Proximal algorithms are a powerful class of optimization algorithms designed to solve mathematical optimization problems that are nonsmooth (non-differentiable), constrained, large-scale, or distributed. They excel where Newton’s method and standard Stochastic Gradient Descent (SGD) hit a mathematical wall or become too slow to be practical. Proximal algorithms are foundational to modern data science, machine learning, and signal processing because they elegantly resolve major bottlenecks that break traditional calculus-based algorithms: handling nonsmooth objective functions, incorporating complex constraints, and efficiently solving large-scale optimization problems that are difficult or impractical to tackle using conventional gradient-based methods.

Introduction to Criminology (2nd Canadian Edition) by Shereen Hassan and Dan Lett (2026) is now in @ChapterPal's collection of open textbooks. This is an accessible, open criminology textbook that connects foundational theories to Indigenous knowledge and critical perspectives, helping students examine how power and colonialism shape ideas about crime. The book progresses from foundational questions about the meaning and social construction of crime to crime categories and patterns, then to media, race, research methods, and explanations of criminal behaviour. Biological, psychological, and sociological theories are presented as approaches with different assumptions and limits, rather than as single, final answers. Later chapters extend this base through learning theories, critical and feminist criminology, cultural criminology, victimology, green criminology, crimes of the powerful, organised crime, and place-based analysis. The closing treatment of restorative and transformative justice connects explanations of harm to alternatives in response. The structure thus moves from defining and studying crime toward interpreting its causes, uneven effects, and possible forms of prevention, accountability, and repair.

An Introduction to the Theory of Numbers by Leo Moser (2004) is now in @ChapterPal's collection of open textbooks. The theory of numbers is a major branch of pure mathematics dedicated to studying the properties of integers and the relationships between them. Often called "The Queen of Mathematics," it focuses heavily on the building blocks of numbers: prime numbers Historically, number theory was considered the purest form of mathematics with no real-world applications. Today, it forms the absolute foundation of modern digital security, cryptography, and computer science. Read the textbook with an AI tutor: chapterpal.com/ebook/4303bca…

3D Game Development with LWJGL 3 by Antonio Hernández Bejarano (2016) is now in @ChapterPal's collection of open textbooks. LWJGL (Lightweight Java Game Library) is an open-source software library that provides Java developers access to high-performance cross-platform libraries, primarily used for game development and graphics programming. It acts as a low-level bridge (or "wrapper") between Java and native C/C++ libraries. Instead of providing a full game engine, it gives you the raw tools to talk directly to your computer's hardware. The book presents a hands-on path from a basic Java window to the core techniques of 3D game development with OpenGL and LWJGL 3, helping readers understand graphics programming by building a game engine from the ground up.

The Concise TypeScript Book by Simone Poggiali (2023) is now in @ChapterPal's collection of open textbooks. TypeScript is a free, open-source programming language developed by Microsoft that builds on top of JavaScript by adding static typing. It is considered a "superset" of JavaScript, meaning that any valid JavaScript code is also valid TypeScript code. Because web browsers and servers cannot run TypeScript directly, a compiler transpiles (converts) the code back into clean, standard JavaScript before it is deployed. Essentially, TypeScript acts as a strict development-time safety net to make writing complex applications smoother. The textbook presents a practical, concise guide to TypeScript’s type system, compiler behavior, setup, and modern JavaScript support, helping developers write safer code and use TypeScript effectively in real projects.

Elements of Kotlin by Mark L. Murphy (2021) is now in @ChapterPal's collection of open textbooks. Kotlin is a modern, statically typed, cross-platform programming language developed by JetBrains. It is officially designated by Google as the preferred language for Android app development, though it is widely used across backend, web, and data science ecosystems. Designed as a sleek, practical alternative to Java, Kotlin fixes many of Java’s historic pain points while maintaining 100% interoperability with existing Java code and libraries.

Comprehensive Rust by Martin Geisler (2022) is now in @ChapterPal's collection of open textbooks. The book presents a practical, interactive path from Rust fundamentals to advanced topics, helping programmers understand ownership, borrowing, and the language’s safety guarantees through runnable examples. In my opinion, Rust is becoming one of the rare programming languages people will still be hired to code by hand due to its C-like efficiency and built-in safety qualities, making it the language used in mission-critical applications where no vibe-coder should be allowed.

Another awesome release on @ChapterPal: Lessons in Industrial Automation by Tony R. Kuphaldt (2018). Lessons in Industrial Automation by Tony R. Kuphaldt is a series of five textbook volumes for instrument technicians, process control specialists, automation engineers, and instructors. Requiring only basic algebra and physical intuition, it begins with fundamentals like electrical circuits, fluid mechanics, calculus, and chemistry, then moves on to measurement devices, analog and pneumatic signals, and digital networks such as Modbus and FOUNDATION Fieldbus. The book’s core covers PID control, loop tuning, and advanced control strategies, along with relay logic, PLC programming, safety systems, calibration, and cybersecurity. Through hands-on procedures, readers learn to install, calibrate, program, and troubleshoot the devices found in modern processing facilities. It deliberately excludes topics like enterprise IT, robotics, and model predictive control, focusing instead on practical instrumentation and operational technology. The five volumes altogether have 2,586 pages and 2,424 isllustrations, so veritually one illustration per page, and plenty of practical advice and real industrial settings photos.

Topological Obstructions to Stability and Stabilization by Wouter Jongeneel and Emmanuel Moulay (2023) is now in @ChapterPal's collection of open textbooks. The textbooks is about controllers. A controller is a rule that turns measurements into actions: a thermostat uses temperature to switch heating, cruise control uses speed to adjust throttle, and a drone uses orientation to adjust motor thrust. As an engineer, you design or program that rule to make a system reach a target and remain stable. This book explains when your requirements are mathematically impossible for the type of controller you chose, regardless of tuning. For robots and systems involving rotations, geometry can prevent one continuous control rule from stabilizing every starting configuration. Read it to understand when to stop tuning and change the design—for example, by switching between control rules. Read the book with an AI tutor: chapterpal.com/ebook/c0146ad…
