Programming Crystal
Author: Ivo Balbaert

ISBN: 1680506641
Category : Computers
Languages : en
Pages : 345
Book Description
Crystal is for Ruby programmers who want more performance, or for developers who enjoy working in a high-level scripting environment. Crystal combines native execution speed and concurrency with Ruby-like syntax, so you will feel right at home. This book, the first available on Crystal, shows you how to write applications that have the beauty and elegance of a modern language, combined with the power of types and modern concurrency tooling. Now you can write beautiful code that runs faster, scales better, and is a breeze to deploy. Crystal is elegant to read and easy to program like Ruby, allowing full object-oriented development. Its compiler is powerful enough to nearly always infer the type of your variables. So you get the benefits of a statically typed language: more robust code, safety and execution speed, while still reaching high productivity in development. Null pointer exceptions as in JavaScript, Java or C#, are a thing of the past: Crystal annihilates them, just like Rust. Explore the building blocks and design of the language, and how you can use the Crystal tool-chain to build and manage powerful applications. Harness the power of the macro system, as well as how to work with fibers and channels, making concurrency as easy as possible. Learn how to use the Kemal web framework and access databases, and how to tap the potential of existing Crystal libraries. Find the spot that Crystal fills in today's software world with real-world examples. With Crystal, you can combine the best of both worlds: the high-level coding of dynamic languages, and the safety and blazing performance of a natively compiled language. What You Need: To develop in Crystal, you only need Crystal v 0.26 the latest version, a common text editor and a browser.

Pages : 176
Book Description
A full-color guide to programming crystals and harnessing their full potential • Explains how to program crystals and gemstones with specific healing intentions as well as how to cleanse and charge your crystals and prepare your own energy field • Provides detailed instructions for working with 8 key crystals, as well as healing and programming guidance for more than 60 well-known and important crystals • Includes vibrant photographs to convey each crystal’s individual powers In this vibrantly illustrated crystal guide, experienced holistic therapist and crystal-healing teacher Sharon McAllister offers an introduction to programming crystals and gemstones to harness their full potential. She explains how crystal programming combines the powerful instrument of intention setting with the healing energies of stones. She details how to cleanse and charge your crystals and prepare your own energy field before programming and provides a collection of intention-setting statements and programming recipes for personal healing as well as therapeutic use. Unveiling the light that each crystal radiates vibrationally and spiritually, Sharon reveals how each crystal is a living being that can be awakened to emanate its purest and strongest energy in alignment with specific healing purposes. She explains the dormant state of stones when they are still inside the earth, their activated state when extracted by humans, and their ignited state, when they are called into direct service with a programmed focus, which leads them to unfold their full healing potential. Focusing on 8 key crystals, including rose quartz, amethyst, and citrine, Sharon shows how these 8 stones can combine to form a powerful toolkit with a wide range of healing applications. She provides an in-depth chapter on each of the 8 key crystals, offering deep insight into their energies and healing properties. She also covers more than 60 additional crystals along with guidance on their healing uses and programming potential. Taking your crystal healing experience to a higher level, this guide shows how each crystal has its own life plan just like human beings and when a crystal enters your life it is never by coincidence.

Crystal Reports .NET Programming
Author: Brian Bischof
Publisher: Bischof Systems, Inc.
ISBN: 9780974953656
Category : Computers
Languages : en
Pages : 548
Book Description
I wrote this book from the perspective of a programmer wanting to learn how to integrate reports within a .NET application. I've been working with Crystal Reports since Visual Basic 3 and it's always been difficult to find technical information on report writing. I spent a year and a half researching what .NET programmers need to successfully create, implement and deploy a Crystal Reports application. I even put the book on the internet for everyone to read for free all of last year. This generated an incredible number of emails from programmers telling me what they liked, disliked, and what was missing from the book. I learned that there are two distinct types of .NET programmers using Crystal Reports. The first type of programmer doesn't have much experience with Crystal Reports and wants a series of tutorials to help them build reports from scratch. For this programmer I wrote 13 chapters which teach you everything about adding reports to ASP.NET and Windows applications. It starts with the basics of building reports to adding charts, crosstab reports, sorting and grouping, subreports and using the formula editor with Basic syntax and Crystal syntax. The second type of programmer has been using Crystal Reports for years and is mostly concerned with how to do technical runtime customization of reports. For this programmer I researched and diagrammed the undocumented report object models. I included dozens of examples in both VB.NET and C# to show you how to modify reports, manipulate different data sources (XML, ADO.NET, ODBC, OLE DB, stored procedures with parameters), modify formulas and report parameters, and integrate .NET with the RAS and RDC. The dozens of emails I received when the book was online were instrumental for doing a major revision of many chapters before publishing the book in hardcopy format. Since releasing the book I continue to receive more emails from people. They regret that the free book isn't online anymore, but understand that it couldn't last forever and that the hardcopy version is even better. I hope you like it and that it helps you achieve your reporting goals. September 2004 Update: Due to high demand, I did a second printing of the book. I took advantage of this opportunity to go through the book and remove all grammatical errors. The content is the same, but the typos have been corrected.
