This is an open-source introduction to Bash scripting guide/ebook that will help you learn the basics of Bash scripting and start writing awesome Bash scripts that will help you automate your daily SysOps, DevOps, and Dev tasks. No matter if you are a DevOps/SysOps engineer, developer, or just a Linux enthusiast, you can use Bash scripts to combine different Linux commands and automate boring and repetitive daily tasks, so that you can focus on more productive and fun things. The guide is suitable for anyone working as a developer, system administrator, or a DevOps engineer and wants to learn the basics of Bash scripting. The first 13 chapters would be purely focused on getting some solid Bash scripting foundations then the rest of the chapters would give you some real-life examples and scripts.

The Ray Tracing in One Weekend series of books are now available to the public for free online. They are now released under the CC0 license. This means that they are as close to public domain as we can get. (While that also frees you from the requirement of providing attribution, it would help the overall project if you could point back to this web site as a service to other users.) These books are formatted for printing directly from your browser, where you can also (on most browsers) save them as PDF. In Ray Tracing in One Weekend, you will build a simple brute-force path tracer. Continuing with Ray Tracing: The Next Week, you will add textures, volumes (like fog), rectangles, instances, lights, and support for lots of objects using a bounding volume hierarchy (BVH). Finally, with Ray Tracing: The Rest Of Your Life, we'll dive into the math of creating a very serious ray tracer.

viewstate is a decoder and encoder for ASP .Net viewstate data. It supports the different viewstate data formats and can extract viewstate data direct from web pages. viewstate will also show any hash applied to the viewstate data.

HTML Purifier is a standards-compliant HTML filter library written in PHP. HTML Purifier removes all malicious code (better known as XSS) with a thoroughly audited and secure yet permissive whitelist, and ensure standards compliance.

Identityflow provides a framework for building protocol flows that perform distributed Identity operations. Examples of Identity Operations are Single Sign-On (SSO) and Attribute queries.

The first truly secure and intuitive templates for PHP. The most common critical vulnerability in websites is Cross-Site Scripting (XSS). It allows an attacker to insert a malicious script into a page that executes in the browser of an unsuspecting user. It can modify the page, obtain sensitive information or even steal the user's identity. Templating systems fail to defend against XSS. Latte is the only system with an effective defense, thanks to context-sensitive escaping. Latte is based on PHP, whereas Twig is based on Python. A designer in Latte doesn't have to constantly switch between two different conventions. Stay in touch. The plugin for Tracy informs you on each page which templates and which variables are being rendered. Latte has native support in NetBeans and an excellent plugin for PhpStorm that suggests tags, filters and PHP code. Latte is a next generation templating system – it understands HTML.

SecureProxy is an proxy application which sits in front of a web server and enforces general security policies which prevent clients from accessing restricted portions of the website or providing dangerous or unauthorized input.

This library contains utility classes such as a converter from plain text to HTML (for safe inclusion of user-supplied text into web pages, avoiding XSS attacks, etc.), converters from binary to hex representation, and similar functions
