Programming Elixir 1.6 - Dave Thomas - Bog - The Pragmatic Programmers - Plusbog.dk

This book is the introduction to Elixir for experienced programmers, completely updated for Elixir 1.6 and beyond. Explore functional programming without the academic overtones (tell me about monads just one more time). Create concurrent applications, butget them right without all the locking and consistency headaches. Meet Elixir, a modern, functional, concurrent language built on the rock-solid Erlang VM. Elixir''s pragmatic syntax and built-in support for metaprogramming will make you productive and keep you interestedfor the long haul. Maybe the time is right for the Next Big Thing. Maybe it''s Elixir. Functional programming techniques help you manage the complexities of today''s real-world, concurrent systems; maximize uptime; and manage security. Enter Elixir, with its modern, Ruby-like, extendable syntax, compile and runtime evaluation, hygienic macro system, and more. But, just as importantly, Elixir brings a sense of enjoyment to parallel,functional programming. Your applications become fun to work with, and the language encourages you to experiment. Part 1 covers the basics of writing sequential Elixir programs. We''ll look at the language, the tools, and the conventions. Part 2 uses these skills to start writing concurrent code-applications that use all the cores on your machine, or all the machines on your network! And we do it both with and without OTP. Part 3 looks at the more advanced features of the language, from DSLs and code generation to extending the syntax. This edition is fully updated with all the new features of Elixir 1.6, with a new chapter on structuring OTP applications, and new sections on the debugger, code formatter, Distillery, and protocols. What You Need: You''ll need a computer, a little experience with another high-levellanguage, and a sense of adventure. No functional programmingexperience is needed.

Machine Learning in Elixir - Sean Moriarity - Bog - The Pragmatic Programmers - Plusbog.dk

Machine Learning in Elixir - Sean Moriarity - Bog - The Pragmatic Programmers - Plusbog.dk

Stable Diffusion, ChatGPT, Whisper - these are just a few examples of incredible applications powered by developments in machine learning. Despite the ubiquity of machine learning applications running in production, there are only a few viable language choices for data science and machine learning tasks. Elixir''s Nx project seeks to change that. With Nx, you can leverage the power of machine learning in your applications, using the battle-tested Erlang VM in a pragmatic language like Elixir. In this book, you''ll learn how to leverage Elixir and the Nx ecosystem to solve real-world problems in computer vision, natural language processing, and more. The Elixir Nx project aims to make machine learning possible without the need to leave Elixir for solutions in other languages. And even if concepts like linear models and logistic regression are new to you, you''ll be using them and much more to solve real-world problems in no time. Start with the basics of the Nx programming paradigm - how it differs from the Elixir programming style you''re used to and how it enables you to write machine learning algorithms. Use your understanding of this paradigm to implement foundational machine learning algorithms from scratch. Go deeper and discover the power of deep learning with Axon. Unlock the power of Elixir and learn how to build and deploy machine learning models and pipelines anywhere. Learn how to analyze, visualize, and explain your data and models. Discover how to use machine learning to solve diverse problems from image recognition to content recommendation - all in your favorite programming language. What You Need: You''ll need a computer with a working installation of Elixir v1.12 and Erlang/OTP 24. For some of the more compute intensive examples, you''ll want to use EXLA, which currently only supports x86-64 platforms. While not explicitly required, some examples will demonstrate programs running on accelerators such as CUDA/ROCm enabled GPUs and Google TPUs. Most of these programs will still run fine on a regular CPU, just for much longer periods of time.

Franciscans and the Elixir of Life - Zachary A. Matus - Bog - University of Pennsylvania Press - Plusbog.dk

Franciscans and the Elixir of Life - Zachary A. Matus - Bog - University of Pennsylvania Press - Plusbog.dk

One of the major ambitions of medieval alchemists was to discover the elixir of life, a sovereign remedy capable not only of healing the body but of transforming it. Given the widespread belief that care for the body came at the cost of care for the soul, it might seem surprising that any Franciscan would pursue the elixir, but those who did were among its most outspoken and optimistic advocates. They believed they could distill a substance that would purify, transmute, and ennoble the human body as well as the soul. In an age when Christians across Europe were seeking material evidence for their faith and corporeal means of practicing their devotion, alchemy, and the elixir in particular, offered a way to bridge the terrestrial and the celestial.Framed as a history around science, Franciscans and the Elixir of Life focuses on alchemy as a material practice and investigates the Franciscan discourses and traditions that shaped the pursuit of the elixir, providing a rich examination of alchemy and religiosity. Zachary A. Matus makes new connections between alchemy, ritual life, apocalypticism, and the particular commitment of the Franciscan Order to the natural world, shedding new light on the question of why so many people claimed to have made, seen, or used alchemical compounds that could never have existed.

Network Programming in Elixir and Erlang - Andrea Leopardi - Bog - The Pragmatic Programmers - Plusbog.dk

Network Programming in Elixir and Erlang - Andrea Leopardi - Bog - The Pragmatic Programmers - Plusbog.dk

TCP, UDP, DNS, HTTP, and more: these are the network protocols that make up the fabric of the Internet. Erlang and Elixir are the perfect fit for building network-intensive applications—the BEAM''s actor model perfectly mirrors the way nodes operate in a network. Learn about networking and the power of the BEAM to write performant and reliable network applications. Create systems that are scalable, resilient, and efficient, thanks to language primitives and OTP. Take advantage of an ecosystem that has been solving network problems for more than thirty years. Learn about design patterns and common pitfalls for network applications on the BEAM. From smart appliances to gigantic data centers, from phones to satellites, networks are the way computers talk to each other. Learn how to use network protocols, choose or design serialization protocols, and architect systems with servers and clients. Start with the most widely-used protocol on the Internet: TCP. Build a chat server where multiple clients can chat in real time. Explore client-side TCP by building a client for Redis. Scale and harden server and client, thanks to features of the BEAM. Then dig into UDP, TCP''s "looser" sibling. Code a system for reporting metrics capable of rivaling hardened software like StatsD. Learn about DNS, which powers domain resolution for the Internet. Next, secure your TCP traffic with TLS. Lastly, explore HTTP, the protocol that even your microwave could be using. Build a JSON API, client, and server. Learn the differences between HTTP/1.1 and HTTP/2, and add real-time features via WebSockets. The BEAM was built for networks and has been honed for more than three decades. It''s the perfect fit. Leverage years of real-world experience building network-intensive applications from a member of the Elixir core team, and become an expert at network programming in Elixir and Erlang. What You Need: You''ll need a computer running a standard distribution of Erlang/OTP, and optionally Elixir. Any recent version of OTP (22 or later) and Elixir (1.11 or later) is fine. For some parts of the book, you''ll also need a working Internet connection.

Engineering Elixir Applications - Josep Giralt D'lacoste - Bog - Pragmatic Bookshelf - Plusbog.dk

Engineering Elixir Applications - Josep Giralt D'lacoste - Bog - Pragmatic Bookshelf - Plusbog.dk

The days of separate dev and ops teams are over - knowledge silos and the "throw it over the fence" culture they create are the enemy of progress. As an engineer or developer, you need to confidently own each stage of the software delivery process. This book introduces a new paradigm, BEAMOps, that helps you build, test, deploy, and debug BEAM applications. Create effective development and deployment strategies; leverage continuous improvement pipelines; and ensure environment integrity. Combine operational orchestrators such as Docker Swarm with the distribution, fault tolerance, and scalability of the BEAM, to create robust and reliable applications. BEAMOps starts by building a solid foundation for your project. On the infrastructure side, see how to use Terraform before you even start coding to automate your deployment and operations. On the project management side, we show you how to use issues and milestones to simplify tracking; you''ll use this foundation as you go through the book, implementing each of the steps required to deploy a scalable Elixir application. Now that you have a foundation, you can start building. Create a Phoenix LiveView application and explore mix releases. Make your deployments reliable with Docker. Continuously improve your codebase by implementing an efficient continuous deployment/integration pipeline with GitHub Actions. Scale the Phoenix LiveView application and operate a distributed BEAMsystem in production using AWS EC2 nodes, AWS load balancers, and a remote Docker swarm. Recognize which application metrics should be collected and monitored, and set alerts when certain thresholds are met to ensure that your application auto-scales. Ship less code more often, and ensure it works! The pragmatic BEAMOps approach that we teach in this book - an extension of the well-known DevOps paradigm - will help you become a multidisciplinary developer who is empowered to own each stage of the software delivery process. After reading this book, you''ll understand how to apply the BEAMOps principles in your daily work, creating reliable, scalable, and easy to understand applications in a cooperative team environment. What You Need: Elixir 1.16.0 (compiled with Erlang/OTP 26) Phoenix framework 1.7.0 Erlang 26.2.1 Terraform v1.7.1 Docker v20.10.22 Packer v1.9.0 Docker Compose v2.21.0 SOPS 3.8.1 Age 1.1.1 An AWS account AWS CLI v2.15.15 A GitHub account GitHub CLI v2.42.1 jq v1.7
