libjpeg-turbo
SIMD-accelerated libjpeg-compatible JPEG codec library
libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface. -

PHPMailer
The classic email sending library for PHP
PHPMailer – A full-featured email creation and transfer class for PHP. Support for UTF-8 content and 8bit, base64, binary, and quoted-printable encodings. SMTP authentication with LOGIN, PLAIN, CRAM-MD5, and XOAUTH2 mechanisms over SMTPS and SMTP+STARTTLS transports. Validates email addresses automatically. Many PHP developers need to send email from their code. The only PHP function that supports this directly is mail(). However, it does not provide any assistance for making use of popular features such as encryption, authentication, HTML messages, and attachments. Formatting email correctly is surprisingly difficult. There are myriad overlapping (and conflicting) standards, requiring tight adherence to horribly complicated formatting and encoding rules – the vast majority of code that you'll find online that uses the mail() function directly is just plain wrong, if not unsafe! -

POSIX Threads for Windows
An implementation of the POSIX threads API for Windows
Also known as "pthreads-win32", POSIX Threads for Windows implements a large subset of the threads related API from the Single Unix Specification Version 3. Conformance and quality are high priorities of this mature library. Development began in 1998 and has continued with numerous significant professional contributions. Please note:- whilst PThreads4W can be built and run by it, MinGW64 includes it's own default POSIX Threads library called "winpthreads". The two are not compatible and in order to build and run PThreads4W (formerly PThreads-WIn32) MinGW64 must be installed without win32pthreads. If you want or need to build and run with PThreads4W then you need to choose win32 threading instead of POSIX when you install MinGW64 to not install the conflicting winpthreads include and library files. -

jQuery
jQuery JavaScript library
jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript. jQuery also supports Node, browser extensions, and other non-browser environments. To build jQuery, you need to have the latest Node.js/npm and git 1.7 or later. Earlier versions might work, but are not supported. Special builds can be created that exclude subsets of jQuery functionality. This allows for smaller custom builds when the builder is certain that those parts of jQuery are not being used. For example, an app that only used JSONP for $.ajax() and did not need to calculate offsets or positions of elements could exclude the offset and ajax/xhr modules. -

Guide to Open Source Libraries
Open source libraries are a form of open source software that is designed to be shared and collaborated on by developers all over the world. Open source libraries consist of pre-written code that can be used in programming projects without having to start from scratch. In other words, instead of having to write all your own code, you can borrow code written by someone else and modify it so it works for your project. This makes development much faster and more efficient.
The most popular open source library is the GNU Library General Public License (GPL) which allows anyone who acquires a copy of the GPL-licensed software to redistribute it freely as long as they provide access to any changes they make when redistributing the modified version. Other less well known but still common open source licenses include BSD, Apache, and MIT license. All these licenses have their own rules when it comes to redistribution but generally require users give credit back to the original developer(s).
When utilized correctly, open source libraries can make coding easier and faster than ever before especially for those new or inexperienced with coding languages like Java or Python. These days there are many different repositories where developers can find countless libraries that could save them time in their programming projects ranging from basic input/output operations up through more advanced multi-dimensional data analysis techniques. Popular sites such as GitHub or SourceForge also offer searchable directories that allow developers quickly locate what they need without having to browse through endless pages trying to find the right library for their needs.
In conclusion, open source libraries are invaluable tools in modern day programming projects providing an easier way for coders all over the world collaborate on common tasks while at the same time eliminating redundant work by reusing existing pieces of code whenever possible.
Features of Open Source Libraries

How Users Can Get Started With Open Source Libraries
Getting started with open source libraries is easy and can save you a lot of time. Here are the steps you need to take:
- Find the Open Source Library You Need:The first step to using open source libraries is finding one that best suits your needs. With so many out there, it can be difficult to decide which one to use. Taking the time to research and choose a library carefully will ensure that you have the right tools for your project. Resources like GitHub or Stack Overflow can help you find suitable libraries.
- Get Familiar with Documentation and Tutorials: Once you’ve chosen an open source library, get familiar with its documentation and tutorials available online. Learning how to properly utilize all of the features provided by a library will make development easier and faster in the long run. This step is especially important if this will be your first experience working with an open source library for your project.
- Download or Clone the Code Repository: After finding a suitable library and reading up on some tutorials, it’s finally time to download or clone (if applicable) its code repository from its hosting platform (GitHub, Bitbucket etc). This may sound intimidating but as long as you pay attention while going through tutorials from point #2 it should be fairly straightforward task.
- Install Necessary Dependencies: In order for most libraries work properly there may be certain dependencies (other programs) needed in order for the code repository work without any hiccups - these are usually listed in documentation associated with each specific library so read carefully here before continuing further. Installing these beforehand should avoid future headaches when running your code on different platforms down the line.
- Set Up Local Environment: With all necessay software installed on your system it's now time to setup local environment which means that everything is ready for testing purposes - having separate environment allows developers not break anything in other projects keep clean versioning system throughout entire process.
