Extract table information from PDF files using OCR and analytics technology
Learn how to build a REST application that provides a web service for converting PDF documents to text using IBM Bluemix. This service accepts a PDF file; converts the PDF file to a text file, capturing identified tables in the document (that is, XML or HTML); and returns the result to the user. The XML version is the output from the OCR engine, while the HTML version is the result of an error-correction process that fixes errors in the table structure identified by the OCR engine.

Improve web application security with jQuery Mobile
Many web developers consider security a low priority. Security is frequently relegated to the end of the software development life cycle, as little more than an afterthought. Sometimes, software security is neglected entirely, resulting in applications rife with common vulnerabilities. Because such bugs might manifest only under conditions present during an attack, they can be hard to detect prior to such events without knowledge of how the exploitation process works. Using a web application built with jQuery Mobile, PHP, and MySQL, this tutorial shows how many types of vulnerabilities occur along with common methods of exploitation and, most importantly, their respective countermeasures.

Build Comet applications using Scala, Lift, and jQuery
Web applications have gotten more and more advanced, and users are always expecting more out of them. One of the most advanced features is Comet, also known as reverse Asynchronous JavaScript and XML (Ajax) or server-side push. Comet allows for browser-based instant messaging, real-time stock quotes, and so on. Advanced Ajax libraries, such as jQuery, make it easy to write Comet applications on the client side, but getting them to scale on the server is still a challenge. That is where the Scala programming language and the Lift Web application framework can step in and deliver a scalable back end for your Comet application. In this tutorial, build a real-time Web auction using these technologies.
