Pandas Brain Teasers
This book contains 25 short programs that will challenge your understanding of Pandas. Like any big project, the Pandas developers had to make some design decisions that at times seem surprising. This book uses those quirks as a teaching opportunity. By understanding the gaps in your knowledge, you'll become better at what you do. Some of the teasers are from the author's experience shipping bugs to production, and some from others doing the same. Teasers and puzzles are fun, and learning how to solve them can teach you to avoid programming mistakes and maybe even impress your colleagues and future employers. Working with data is central to nearly everything we do, from disease contact tracing and analyzing health records to smart meters that track utility consumption behavior. With the power of Python's pandas library, you can process and analyze this data in a highly efficient and simple-to-understand way. And with 25 brain teasers designed to turn this technology's quirks into a ...

Rust Brain Teasers
The Rust programming language is consistent and does its best to avoid surprising the programmer. Like all languages, though, Rust still has its quirks. But these quirks present a teaching opportunity. In this book, you'll work through a series of brain teasers that will challenge your understanding of Rust. By understanding the gaps in your knowledge, you can become better at what you do and avoid mistakes. Many of the teasers in this book come from the author's own experience creating software. Others derive from commonly asked questions in the Rust community. Regardless of their origin, these brain teasers are fun, and let's face it: who doesn't love a good puzzle, right? What better way to exercise your brain and increase your Rust programming knowledge than with a collection of dynamic brain teasers? As you read through each of these puzzles and try to work out the answers, you'll not only learn about Rust's unique quirks and peculiarities, you'll also have loads of fun along t ...

Build a Weather Station with Elixir and Nerves
The Elixir programming language has become a go-to tool for creating reliable, fault-tolerant, and robust server-side applications. Thanks to Nerves, those same exact benefits can be realized in embedded applications. This book will teach you how to structure, build, and deploy production grade Nerves applications to network-enabled devices. The weather station sensor hub project that you will be embarking upon will show you how to create a full stack IoT solution in record time. You will build everything from the embedded Nerves device to the Phoenix backend and even the Grafana time-series data visualizations. Elixir as a programming language has found its way into many different software domains, largely in part to the rock-solid foundation of the Erlang virtual machine. Thanks to the Nerves framework, Elixir has also found success in the world of embedded systems and IoT. Having access to all of the Elixir and OTP constructs such as concurrency, supervision, and immutability mak ...

Powerful Command-Line Applications in Go
Write your own fast, reliable, and cross-platform command-line tools with the Go programming language. Go might be the fastest - and perhaps the most fun - way to automate tasks, analyze data, parse logs, talk to network services, or address other systems requirements. Create all kinds of command-line tools that work with files, connect to services, and manage external processes, all while using tests and benchmarks to ensure your programs are fast and correct. Go is a modern programming language that combines the reliability of compiled languages with the ease of use and flexibility of dynamic typed languages. With Go, you can develop cross-platform command-line tools that are fast and reliable. Work through practical examples to develop elegant and efficient tools by applying Go's rich standard library, its built-in support for concurrency, and its expressive syntax. Use Go's integrated testing capabilities to automatically test your tools, ensuring they work reliably, even across ...

Bash Guide
This guide aims to aid people interested in learning to work with BASH. It aspires to teach good practice techniques for using BASH, and writing simple scripts. This guide is targeted at beginning users. It assumes no advanced knowledge - just the ability to login to a Unix-like system and open a command-line (terminal) interface. It will help if you know how to use a text editor; we will not be covering editors, nor do we endorse any particular editor choice. Familiarity with the fundamental Unix tool set, or with other programming languages or programming concepts, is not required, but those who have such knowledge may understand some of the examples more quickly. ...

FPGAs for Dummies, 2nd Edition
Field programmable gate arrays (FPGAs) are integrated circuits that enable designers to program customized digital logic in the field. FPGAs have been around since the 1980s and were originally conceived to give all design teams the ability to create custom logic. In the early days, using an FPGA in your design meant you had to do a lot of programming just to get your FPGA to perform simple functions, so most designers avoided them. If you haven't looked into FPGAs since your university studies way back when, you'll want to take another look at them. The FPGA has evolved from a useful but humble interface device into a system-level integrated circuit (IC) with its own microprocessors, memory blocks, and interfaces. It's the next big thing. Now would be a great time to get an inexpensive development kit, download free tools, and begin to explore this world for yourself. And this book will help you understand the practical uses of FPGAs.

Cryptography and Cryptanalysis in Java
Here is your in-depth guide to cryptography and cryptanalysis in Java. This book includes challenging cryptographic solutions that are implemented in Java 17 and Jakarta EE 10. It provides a robust introduction to Java 17's new features and updates, a roadmap for Jakarta EE 10 security mechanisms, a unique presentation of the "hot points" (advantages and disadvantages) from the Java Cryptography Architecture (JCA), and more. The book dives into the classical simple cryptosystems that form the basis of modern cryptography, with fully working solutions (encryption/decryption operations). Pseudo-random generators are discussed as well as real-life implementations. Hash functions are covered along with practical cryptanalysis methods and attacks, asymmetric and symmetric encryption systems, signature and identification schemes. The book wraps up with a presentation of lattice-based cryptography and the NTRU framework library. Modern encryption schemes for cloud and big data environme ...
