Julia: High Performance Programming. Build powerful and fast systems with Julia

Ivo Balbaert, M E Sherrington, Avik Sengupta

In this learning path, you will learn to use an interesting and dynamic programming language—Julia! You will get a chance to tackle your numerical and data problems with Julia. You’ll begin the journey by setting up a running Julia platform before exploring its various built-in types. We’ll then move on to the various functions and constructs in Julia. We’ll walk through the two important collection types—arrays and matrices in Julia.You will dive into how Julia uses type information to achieve its performance goals, and how to use multiple dispatch to help the compiler emit high performance machine code. You will see how Julia’s design makes code fast, and you’ll see its distributed computing capabilities.By the end of this learning path, you will see how data works using simple statistics and analytics, and you’ll discover its high and dynamic performance—its real strength, which makes it particularly useful in highly intensive computing tasks. This learning path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products:?

Jumpstart Jamstack Development. Build and deploy modern websites and web apps using Gatsby, Netlify, and Sanity

Christopher Pecoraro , Vincenzo Gambino

Jamstack (JavaScript, API, and Markup) enables web developers to create and publish modern and maintainable websites and web apps focused on speed, security, and accessibility by using tools such as Gatsby, Sanity, and Netlify. Developers working with Jamstack will be able to put their knowledge to good use with this practical guide to static site generation and content management. This Jamstack book takes a hands-on approach to implementation and related methodologies that will have you up and running with modern web development in no time.Complete with step-by-step explanations of essential concepts, practical examples, and self-assessment questions, you'll begin by building an event and venue schema structure, and then expand the functionality, exploring all that the Jamstack has to offer. You’ll learn how an example Jamstack is built, build structured content using Sanity to create a schema, use GraphQL to expose the content, and employ Gatsby to build an event website using page and template components and Tailwind CSS Framework. Lastly, you’ll deploy the website to both, a Netlify server and the Microsoft Static Web Apps Service, and interact with it using Amazon Alexa.By the end of this book, you'll have gained the knowledge and skills you need to install, configure, build, extend, and deploy a simple events website using Jamstack.

Kafka w praktyce. Przetwarzanie strumieniowe i potoki danych o dużej skali. Wydanie II

Gwen Shapira, Todd Palino, Rajini Sivaram, Krit...

Każda aplikacja korporacyjna tworzy dane. Ich przenoszenie i przetwarzanie jest równie ważne jak same dane. Platforma Apache Kafka została zbudowana właśnie w tym celu: aby umożliwić płynną obsługę strumieni zdarzeń czasu rzeczywistego. Umożliwia to architektom nie tylko łączenie aplikacji z systemami danych, ale również budowanie niestandardowych aplikacji, które same w sobie wyzwalają strumienie danych. Okazuje się, że architektura skupiona wokół strumieni zdarzeń otwiera zupełnie nowy rozdział projektowania dużych systemów. Dzięki temu praktycznemu przewodnikowi komfortowo rozpoczniesz pracę z platformą streamingową Apache Kafka. Poznasz najlepsze praktyki w zakresie jej wdrażania i konfiguracji, aby zapewnić sobie możliwość strumieniowego przetwarzania dużych ilości danych. Zaznajomisz się z AdminClient API Kafki, mechanizmem transakcji i z nowymi funkcjonalnościami zabezpieczeń. W książce znajdziesz szczegółowe instrukcje, w jaki sposób wdrażać klastry produkcyjne Kafki, pisać niezawodne mikrousługi oparte na zdarzeniach i budować skalowalne aplikacje przetwarzania strumieniowego. Opisano w niej też gwarancje niezawodności, kluczowe interfejsy API i szczegóły architektury, w tym protokół replikacji, kontroler i warstwę pamięci masowej. Najciekawsze zagadnienia: wdrażanie i konfigurowanie Kafki w praktyce niezawodne dostarczanie danych budowanie potoków danych i aplikacji monitorowanie, dostrajanie i utrzymywanie działania Kafki w środowisku produkcyjnym wskaźniki pomiarów operacyjnych Kafki Kafka w systemach przetwarzania strumieniowego Kafka: gwarancja niezawodności korporacyjnych aplikacji!
