As a leading security engineer, Michal Zalewski has spent his career methodically anticipating and planning for cyberattacks. In Practical Doomsday, Zalewski applies the same thoughtful, rational approach to preparing for disasters of all kinds. By sharing his research, advice, and a healthy dose of common sense, he’ll help you rest easy knowing you have a plan for the worst—even if the worst never comes.
The book outlines a level-headed model for evaluating risks, one that weighs the probability of scenarios against the cost of preparing for them. You’ll learn to apply that model to the whole spectrum of potential crises, from personal hardships like job loss or a kitchen fire, to large-scale natural disasters and industrial accidents, to recurring pop-culture fears like all-out nuclear war. You’ll then explore how basic lifestyle adjustments, such as maintaining a robust rainy-day fund, protecting yourself online, and fostering good relationships with your neighbors, can boost your readiness for a wide range of situations. You’ll also take a no-nonsense look at the supplies and equipment essential to surviving sudden catastrophes, like prolonged power outages or devastating storms, and examine the merits and legal implications of different self-defense strategies.
You’ll learn:
• How to identify and meaningfully assess risks in your life, then develop strategies for managing them
• Ways to build up and diversify a robust financial safety net—a key component of nearly all effective preparedness strategies
• How to adapt your prep plans to a variety of situations, from shelter-in-place scenarios to evacuations by car or on foot
• Sensible approaches to stockpiling food, water, and other essentials, along with recommendations on what supplies are actually worth having
Disasters happen, but they don’t have to dominate your life. Practical Doomsday will help you plan ahead, so you can stop worrying about what tomorrow may bring and start enjoying your life today.

Kill It with Fire chronicles the challenges of dealing with aging computer systems, along with sound modernization strategies.
How to survive a legacy apocalypse
“Kill it with fire,” the typical first reaction to a legacy system falling into obsolescence, is a knee-jerk approach that often burns through tons of money and time only to result in a less efficient solution. This book offers a far more forgiving modernization framework, laying out smart value-add strategies and proven techniques that work equally well for ancient systems and brand-new ones.
Renowned for restoring some of the world’s oldest, messiest computer networks to operational excellence, software engineering expert Marianne Bellotti distills key lessons and insights from her experience into practical, research-backed guidance to help you determine when and how to modernize. With witty, engaging prose, Bellotti explains why new doesn’t always mean better, weaving in illuminating case studies and anecdotes from her work in the field.
You’ll learn:
Where to focus your maintenance efforts for maximum impact and value
How to pick the right modernization solutions for your specific needs and keep your plans on track
How to assess whether your migrations will add value before you invest in them
What to consider before moving data to the cloud
How to determine when a project is finished
Packed with resources, exercises, and flexible frameworks for organizations of all ages and sizes, Kill It with Fire will give you a vested interest in your technology’s future.

A hands-on, problem-based introduction to building algorithms and data structures to solve problems with a computer.
Algorithmic Thinking will teach you how to solve challenging programming problems and design your own algorithms. Daniel Zingaro, a master teacher, draws his examples from world-class programming competitions like USACO and IOI. You'll learn how to classify problems, choose data structures, and identify appropriate algorithms. You'll also learn how your choice of data structure, whether a hash table, heap, or tree, can affect runtime and speed up your algorithms; and how to adopt powerful strategies like recursion, dynamic programming, and binary search to solve challenging problems.
Line-by-line breakdowns of the code will teach you how to use algorithms and data structures like:
The breadth-first search algorithm to find the optimal way to play a board game or find the best way to translate a book
Dijkstra's algorithm to determine how many mice can exit a maze or the number of fastest routes between two locations

You'll begin with basics like creating functions, choosing data types, and binding variables and then move on to more advanced concepts, such as:
• Ownership and borrowing, lifetimes, and traits
• Using Rust's memory safety guarantees to build fast, safe programs
• Testing, error handling, and effective refactoring
• Generics, smart pointers, multithreading, trait objects, and advanced pattern matching
• Using Cargo, Rust's built-in package manager, to build, test, and document your code and manage dependencies
• How best to use Rust's advanced compiler with compiler-led programming techniques
You'll find plenty of code examples throughout the book, as well as three chapters dedicated to building complete projects to test your learning: a number guessing game, a Rust implementation of a command line tool, and a multithreaded server.
New to this edition: An extended section on Rust macros, an expanded chapter on modules, and appendixes on Rust development tools and editions.
