Machine Learning Fundamentals. Use Python and scikit-learn to get up and running with the hottest developments in machine learning

Hyatt Saleh

As machine learning algorithms become popular, new tools that optimize these algorithms are also developed. Machine Learning Fundamentals explains you how to use the syntax of scikit-learn. You'll study the difference between supervised and unsupervised models, as well as the importance of choosing the appropriate algorithm for each dataset. You'll apply unsupervised clustering algorithms over real-world datasets, to discover patterns and profiles, and explore the process to solve an unsupervised machine learning problem.The focus of the book then shifts to supervised learning algorithms. You'll learn to implement different supervised algorithms and develop neural network structures using the scikit-learn package. You'll also learn how to perform coherent result analysis to improve the performance of the algorithm by tuning hyperparameters.By the end of this book, you will have gain all the skills required to start programming machine learning algorithms.

Hands-On Concurrency with Rust. Confidently build memory-safe, parallel, and efficient software in Rust

Brian L. Troutwine

Most programming languages can really complicate things, especially with regard to unsafe memory access. The burden on you, the programmer, lies across two domains: understanding the modern machine and your language's pain-points. This book will teach you to how to manage program performance on modern machines and build fast, memory-safe, and concurrent software in Rust. It starts with the fundamentals of Rust and discusses machine architecture concepts. You will be taken through ways to measure and improve the performance of Rust code systematically and how to write collections with confidence. You will learn about the Sync and Send traits applied to threads, and coordinate thread execution with locks, atomic primitives, data-parallelism, and more.The book will show you how to efficiently embed Rust in C++ code and explore the functionalities of various crates for multithreaded applications. It explores implementations in depth. You will know how a mutex works and build several yourself. You will master radically different approaches that exist in the ecosystem for structuring and managing high-scale systems. By the end of the book, you will feel comfortable with designing safe, consistent, parallel, and high-performance applications in Rust.

Majami. Zły pies

Artur Górski

Rozmowa z najsłynniejszym polskim policyjnym przykrywkowcem. Janek Fabiańczyk, pierwowzór słynnego Majamiego z "Pitbulla" Patryka Vegi, to przykrywkowiec, czyli człowiek z najbardziej elitarnej i najbardziej tajemniczej formacji w polskiej policji. Jako agent przykrywkowy wszedł w struktury gangu mokotowskiego i przyczynił się do jego rozbicia. Jako oficer kryminalny w komendzie stołecznej rozpracował brutalnego bandytę, który zasłynął tym, że swoje ofiary przypalał żelazkiem Za przekroczenie uprawnień trafił do więzienia z wyrokiem wyższym niż zatrzymany przez niego przestępca. Bo w spotkaniach z gangsterami był brutalny i bezkompromisowy. A w więzieniu gliniarz ma gorzej od pedofilów. Jak cienka jest granica między dobrym policjantem i złym psem? Kogo nie toleruje się w polskiej policji? Jak wygląda życie gliny po drugiej stronie więziennych murów? Niecenzurowana opowieść jednego z najskuteczniejszych policjantów w Polsce. Artur Górski dziennikarz, pisarz, autor bestsellerowej rozmowy z Jarosławem Sokołowskim "Masa o kobietach polskiej mafii", nagrodzonej Bestsellerem Empiku 2014 w kategorii literatura faktu, kolejne tomy "Masa o pieniądzach polskiej mafii", "Masa o porachunkach polskiej mafii", "Masa o bossach polskiej mafii", "Masa o kilerach polskiej mafii", "Masa o żołnierzach polskiej mafii", "Masa o życiu świadka koronnego" i "Masa o procesie polskiej mafii" przez wiele miesięcy podbijały listy bestsellerów. W 2017 roku udało mu się w formie książki doprowadzić do spotkania nieprzejednanych wrogów Moniki Banasiak i Jarosława Sokołowskiego, i tak powstała bestsellerowa rozmowa "Słowikowa i Masa. Twarzą w twarz". Poza tym napisał wiele powieści sensacyjnych, m.in. "Gucci Boys", "Al Capone w Warszawie", "Zdrada Kopernika", oraz pozycji z gatunku non-fiction: "Świat tajnych służb", "Gang i Pięść Dawida". Specjalizuje się w problematyce międzynarodowej przestępczości zorganizowanej. Twórca magazynu "Focus Śledczy".

Security Automation with Ansible 2. Leverage Ansible 2 to automate complex security tasks like application security, network security, and malware analysis

Akash Mahajan, MADHU AKULA

Security automation is one of the most interesting skills to have nowadays. Ansible allows you to write automation procedures once and use them across your entire infrastructure. This book will teach you the best way to use Ansible for seemingly complex tasks by using the various building blocks available and creating solutions that are easy to teach others, store for later, perform version control on, and repeat.We’ll start by covering various popular modules and writing simple playbooks to showcase those modules. You’ll see how this can be applied over a variety of platforms and operating systems, whether they are Windows/Linux bare metal servers or containers on a cloud platform. Once the bare bones automation is in place, you’ll learn how to leverage tools such as Ansible Tower or even Jenkins to create scheduled repeatable processes around security patching, security hardening, compliance reports, monitoring of systems, and so on. Moving on, you’ll delve into useful security automation techniques and approaches, and learn how to extend Ansible for enhanced security. While on the way, we will tackle topics like how to manage secrets, how to manage all the playbooks that we will create and how to enable collaboration using Ansible Galaxy. In the final stretch, we’ll tackle how to extend the modules of Ansible for our use, and do all the previous tasks in a programmatic manner to get even more powerful automation frameworks and rigs.

The Northing Tramp

Edgar Wallace

Rather different from the usual Wallace plot, here we have a tramp heading for the Canadian border who marries a girl while in a drunken stupor. Her wedding day was so fraught with danger that she and her husband were forced to flee from the deadly menace that ruthlessly dogged their every move. She learned to avoid the man with the red beard and his swarthy knife-juggling companion. Above all, she feared and avoided Gussie, whose drawl and monocle gave him a deceptive appearance of meekness. Who were these three and who was her strange husband and what was the secret that spelled death between them? Mysterious tramps, Chicago gangsters, and villainous members of the English nobility!
