There's a wealth of data online, but sorting and gathering it by hand can be tedious and time consuming. Rather than click through page after endless page, why not let bots do the work for you? Webbots, Spiders, and Screen Scrapers will show you how to create simple programs with PHP/CURL to mine, parse, and archive online data to help you make informed decisions. Michael Schrenk, a highly regarded webbot developer, teaches you how to develop fault-tolerant designs, how best to launch and schedule the work of your bots, and how to create Internet agents that: –Send email or SMS notifications to alert you to new information quickly –Search different data sources and combine the results on one page, making the data easier to interpret and analyze –Automate purchases, auction bids, and other online activities to save time Sample projects for automating tasks like price monitoring and news aggregation will show you how to put the concepts you learn into practice. This second edition of Webbots, Spiders, and Screen Scrapers includes tricks for dealing with sites that are resistant to crawling and scraping, writing stealthy webbots that mimic human search behavior, and using regular expressions to harvest specific data. As you discover the possibilities of web scraping, you'll see how webbots can save you precious time and give you much greater control over the data available on the Web.

A a thorough, practice-based introduction to WebAssembly. Learn how to create high-performing, lightning-fast websites and applications. WebAssembly is the fast, compact, portable technology that optimizes the performance of resource-intensive web applications and programs. The Art of WebAssembly is designed to give web developers a solid understanding of how it works, when to use it (and when not to), and how to develop and deploy WebAssembly apps. First you’ll learn how to optimize and compile low-level code, debug and evaluate WebAssembly, and represent WebAssembly in the human-readable WebAssembly Text (WAT) format. Once you have the basics down, you’ll build a browser-based collision detection program, work with browser rendering technologies to create graphics and animations, and see how WebAssembly interacts with other web languages. You’ll also learn how to: Embed WebAssembly applications in web browsers and Node.js Use browser debuggers to evaluate your WebAssembly code Format variables, loops, functions, strings, data structures, and conditional logic in WAT Manipulate memory Build a program that generates graphical objects and detects when they collide Evaluate the output of a WebAssembly compiler The Art of WebAssembly will help you make sense of this powerful technology to boost the performance of your web applications.
