wkhtmltopdf
Convert HTML to PDF using Webkit (QtWebKit)
wkhtmltopdf and wkhtmltoimage are open source (LGPLv3) command line tools to render HTML into PDF and various image formats using the Qt WebKit rendering engine. These run entirely "headless" and do not require a display or display service. There is also a C library, if you're into that kind of thing. The file pdf.h contains a fairly high level and stable pure c binding to wkhtmltopdf. These binding are well documented and do not depend on QT. Using this is the recommended way of interfacing with the PDF portion of libwkhtmltox. The rest of the headers directly exposes the C++ QT dependent class used internally by wkhtmltopdf and wkhtmltoimage. wkhtmltopdf is able to put several objects into the output file, an object is either a single webpage, a cover webpage or a table of contents. The objects are put into the output document in the order they are specified on the command line, options can be specified on a per object basis or in the global options area. -

Dompdf
HTML to PDF converter for PHP
dompdf is an HTML to PDF converter. At its heart, dompdf is (mostly) a CSS 2.1 compliant HTML layout and rendering engine written in PHP. It is a style-driven renderer, it will download and read external stylesheets, inline style tags, and the style attributes of individual HTML elements. It also supports most presentational HTML attributes. PDF rendering is currently provided either by PDFLib or by a bundled version the R&OS CPDF class written by Wayne Munro. (Some important changes have been made to the R&OS class, however). In order to use PDFLib with dompdf, the PDFLib PECL extension is required. Using PDFLib improves performance and reduces the memory requirements of dompdf somewhat, while the R&OS CPDF class, though slightly slower, eliminates any dependencies on external PDF libraries. -

geckodriver
WebDriver for Firefox
geckodriver is an implementation of WebDriver, and WebDriver can be used for widely different purposes. How you invoke geckodriver largely depends on your use case. If you are using geckodriver through Selenium, you must ensure that you have version 3.11 or greater. Because geckodriver implements the W3C WebDriver standard and not the same Selenium wire protocol older drivers are using, you may experience incompatibilities and migration problems when making the switch from FirefoxDriver to geckodriver. Generally speaking, Selenium 3 enabled geckodriver as the default WebDriver implementation for Firefox. With the release of Firefox 47, FirefoxDriver had to be discontinued for its lack of support for the new multi-processing architecture in Gecko. Since geckodriver is a separate HTTP server that is a complete remote end implementation of WebDriver, it is possible to avoid using the Selenium remote server if you have no requirements to distribute processes across a matrix of systems. -

Twemoji
Simple library that provides standard Unicode emoji for all platforms
Twitter’s open source emoji has you covered for all your project's emoji needs. With support for the latest Unicode emoji specification, featuring 3,245 emojis, and all for free. As an open source project, attribution is critical from a legal, practical and motivational perspective in our opinion. The graphics are licensed under the CC-BY 4.0 which has a pretty good guide on best practices for attribution. Although there are two kinds of parsing supported by this utility, we recommend you use DOM parsing, explained below. Each type of parsing accepts a callback to generate an image source or an options object with parsing info. The second kind of parsing is string parsing. This is unrecommended because this method does not sanitize the string or otherwise prevent malicious code from being executed; such sanitization is out of scope. -

Simple.css
Simple.css is a classless CSS template to make a good website
A classless CSS framework that makes semantic HTML look good. By classless I mean that there are no CSS classes anywhere in the CSS or the HTML. So your website can look just like this using plain old vanilla HTML. When starting a new project, I wanted a CSS framework that would get me up and running quickly, and give me something I could hack on. I got sick of all these giant frameworks that include everything but the kitchen sink, 90% of which I’ll never use. For example, the minified CSS for the Bootstrap framework is 144KB in total. By comparison, Simple.css is around 4KB. Obviously Simple.css and Bootstrap don’t compare in terms of their functionality, but Simple.css allows website developers to spin something up very quickly that looks good and needs very little work. By using something like Simple.css, provides the basics to get up and running quickly (or just use it as-is for a simple, good-looking site) yet not have to learn an extremely convoluted framework.
