AngleSharp is a .NET library that gives you the ability to parse angle bracket based hyper-texts like HTML, SVG, and MathML. XML without validation is also supported by the library. An important aspect of AngleSharp is that CSS can also be parsed. The included parser is built upon the official W3C specification. This produces a perfectly portable HTML5 DOM representation of the given source code and ensures compatibility with results in evergreen browsers. Also standard DOM features such as querySelector or querySelectorAll work for tree traversal.

Managing large application state easily, resiliently, and with high performance is one of the hardest problems in the cloud today. The FASTER project offers two artifacts to help tackle this problem. 
 
FASTER Log is a high-performance concurrent persistent recoverable log, iterator, and random reader library in C#. It supports very frequent commit operations at low latency, and can quickly saturate disk bandwidth. It supports both sync and async interfaces, handles disk errors, and supports checksums.
 
FASTER KV is a concurrent key-value store + cache (available in C# and C++) that is designed for point lookups and heavy updates. FASTER supports data larger than memory, by leveraging fast external storage (local or cloud). It also supports consistent recovery using a fast non-blocking checkpointing technique that lets applications trade-off performance for commit latency.

GraphicsMagick is the swiss army knife of image processing. It provides a robust and efficient collection of tools and libraries which support reading, writing, and manipulating an image in over 88 major formats including important formats like DPX, GIF, JPEG, JPEG-2000, PNG, PDF, PNM, and TIFF. GraphicsMagick supports huge images and has been tested with gigapixel-size images. GraphicsMagick can create new images on the fly, making it suitable for building dynamic Web applications. GraphicsMagick may be used to resize, rotate, sharpen, color reduce, or add special effects to an image and save the result in the same or differing image format. Image processing operations are available from the command line, as well as through C, C++, Perl, PHP, Tcl, Ruby, or Windows COM programming interfaces. With some modification, language extensions for ImageMagick may be used. GraphicsMagick is originally derived from ImageMagick 5.5.2 but has been completely independent of the ImageMagick project since then. Since the fork from ImageMagick in 2002, many improvements have been made by many authors using an open development model but without breaking the API or utilities operation. GraphicsMagick is used to process billions of files at the world's largest photo sites (e.g. Flickr).

Tantivy is a full text search engine library written in rust. It is closer to Lucene than to Elastic Search and Solr in the sense it is not an off-the-shelf search engine server, but rather a crate that can be used to build such a search engine.
 
Its features include: 
<ul>
<li>Full-text search</li>
<li>Configurable tokenizer (stemming available for 17 Latin languages with third party support for Chinese (<a href="https://crates.io/crates/tantivy-jieba" target="_blank" rel="nofollow">tantivy-jieba</a> and <a href="https://crates.io/crates/cang-jie" rel="nofollow">cang-jie</a>), Japanese (<a href="https://github.com/lindera-morphology/lindera-tantivy">lindera</a> and <a href="https://crates.io/crates/tantivy-tokenizer-tiny-segmenter" rel="nofollow">tantivy-tokenizer-tiny-segmenter</a>) and Korean (<a href="https://github.com/lindera-morphology/lindera-tantivy">lindera</a> + <a href="https://github.com/lindera-morphology/lindera-ko-dic-builder">lindera-ko-dic-builder</a>)</li>
<li>Fast (check out the <g-emoji class="g-emoji" alias="racehorse" fallback-src="https://github.githubassets.com/images/icons/emoji/unicode/1f40e.png">🐎</g-emoji> <g-emoji class="g-emoji" alias="sparkles" fallback-src="https://github.githubassets.com/images/icons/emoji/unicode/2728.png">✨</g-emoji> <a href="https://tantivy-search.github.io/bench/" rel="nofollow">benchmark</a> <g-emoji class="g-emoji" alias="sparkles" fallback-src="https://github.githubassets.com/images/icons/emoji/unicode/2728.png">✨</g-emoji> <g-emoji class="g-emoji" alias="racehorse" fallback-src="https://github.githubassets.com/images/icons/emoji/unicode/1f40e.png">🐎</g-emoji>)</li>
