The GNU Debugger allows you to see what is going on "inside" a program while it executes - or what a program was doing at the moment it crashed. GDB supports C, C++, Java, Fortran and Assembly among other languages; it is also designed to work closely with the GNU Compiler Collection (GCC). The GNU Debugger Program has four special featur...

Svelte is an exciting Web framework that offers a fresh new take on how to build Web applications. If you are already experienced in React, Vue, Angular or other frontend frameworks you might be pleasantly surprised by Svelte. My first impression with Svelte was that it all feels so much more like plain JavaScript than working with other fram...

This is an intro to C for folks who already know how to program in another language.

The goal is to keep this up-to-date with the latest C standards. This guide assumes that ...

Back in the mid 90s, Beej got tired of all his friends asking him how to do this stuff with networking programming in C, so he put pen to paper on the early World Wide Web and wrote down everything he knew just to get them off his back. Since then, the Guide has expanded significantly, with plenty of examples, and covers IPv6. Inside you'll fi...

In Performing Deception, Brian Rappert reconstructs the practice of entertainment magic by analysing it through the lens of perception, deception and learning, as he goes about studying conjuring himself. Through this novel meditation on reasoning and skill, Rappert elevates magic from the undertaking of mere trickery to an art that offers the b...

Climate Crisis Economics draws on economics, political economy, scientific literature, and data to gauge the extent to which our various communities - political, economic, business - are making the essential leap to a new narrative and policy approach that will accelerate us towards the necessary transition to a decarbonized economy and sustainable...

Statistical studies over the last forty-five years show that, although there are success stories, very many mergers and acquisitions do not result in the increased operating profits that economics textbooks would lead one to expect. As consultancy McKinsey have put it, 'Anyone who has researched merger success rates knows that roughly 70% fail...

This work introduces a new specification and verification approach for dynamic systems. The introduced approach is able to provide type II error free results by definition, i.e. there are no hidden faults in the verification result. The approach is based on Kaucher interval arithmetic to enclose the measurement in a bounded error sense. The develop...

Linux crash analysis - this is a subject that has lots of unanswered mail threads and plain text documents scattered all over the place, inaccessible to almost everyone, save the tiny percentage of super geeks. My personal and professional interest in the last three years has taken me down the path of Linux kernel secrets, all the way into assem...

In this magisterial book, William St Clair unfolds the history of the Parthenon throughout the modern era to the present day, with special emphasis on the period before, during, and after the Greek War of Independence of 1821 - 32. Focusing particularly on the question of who saved the Parthenon from destruction during this conflict, with the help ...

Everyone needs a little cryptology. The problem with crypto is that it has a reputation of being very hard and mysterious, as well as very easy to get wrong. While there are aspects of crypto that are connected to quite modern and complex theories - such as number theory, an old and deep branch of mathematics; complexity theory, a new(er) and su...

This course is organized around algorithmic issues that arise in machine learning. Modern machine learning systems are often built on top of algorithms that do not have provable guarantees, and it is the subject of debate when and why they work. In this class, we focus on designing algorithms whose performance we can rigorously analyze for fundamen...

How To Do Science has been written for students of the life sciences who are actively engaged in the scientific process. This guide introduces you to what it means to be a scientist. You will learn about the scientific method and how to carry out many tasks of a scientist, including: designing experiments, visualising data, accessing scientific lit...

This 2d volume describes the systematic application of Promise Theory to systems, representing a significant step forward in describing functional systems with both dynamics and semantics. By combining quantitative and qualitative descriptions in a single framework, Promise Theory provides the first impartial language for multiscale system phenomen...

This book provides an algorithmic perspective to autonomous robotics to students with a sophomore-level of linear algebra and probability theory. Robotics is an emerging field at the intersection of mechanical engineering, electrical engineering, and computer science. With computers becoming more powerful, making robots smart is getting more and mo...

Existing textbooks on international relations treat history in a cursory fashion and perpetuate a Euro-centric perspective. This textbook pioneers a new approach by historicizing the material traditionally taught in International Relations courses, and by explicitly focusing on non-European cases, debates and issues. The volume is divided into thre...
