Cairo is a 2D Vector graphics library with support for multiple output devices. Currently supported output targets include the X Window System, Quartz, Win32, image buffers, PostScript, PDF, and SVG file output. Experimental backends include OpenGL (through glitz), XCB, BeOS, OS/2, and DirectFB. Cairo is designed to produce consistent output on all output media while taking advantage of display hardware acceleration when available (eg. through the X Render Extension). The cairo API provides operations similar to the drawing operators of PostScript and PDF. Operations in cairo including stroking and filling cubic Bézier splines, transforming and compositing translucent images, and antialiased text rendering. All drawing operations can be transformed by any affine transformation (scale, rotation, shear, etc.)

PumpkinDB is a event sourcing database engine that doesn't overwrite data. It features include Immutable key/value storage, ACID transactions, Binary keys and values (allows any encoding to be used: JSON, XML, Protobuf, Cap'n Proto, etc.), An embedded programming language (PumpkinScript), A range of event indexing and querying primitives.
 
The core ideas behind PumpkinDB stem from the so called lazy event sourcing approach which is based on storing and indexing events while delaying domain binding for as long as possible. That said, the intention of this database is to be a building block for different kinds of event sourcing systems, ranging from the classic one (using it as an event store) all the way to the lazy one (using indices) and anywhere in between. It's also possible to implement different approaches within a single database for different parts of the domain.
