Sphinx is an open source full text search server, designed from the ground up with performance, relevance (aka search quality), and integration simplicity in mind. It's written in C++ and works on Linux (RedHat, Ubuntu, etc), Windows, MacOS, Solaris, FreeBSD, and a few other systems. Sphinx lets you either batch index and search data stored in an SQL database, NoSQL storage, or just files quickly and easily or index and search data on the fly, working with Sphinx pretty much as with a database server. A variety of text processing features enable fine-tuning Sphinx for your particular application requirements, and a number of relevance functions ensures you can tweak search quality as well.

SPI is an acronym for the most common cloud computing service models, Software as a Service, Platform as a Service and Infrastructure as a Service. 

SpiderScribe is an online mind-mapping tool to organize thoughts and ideas into maps, adding text, images, files, geographical maps, and calendar events to create unique and free-form maps.

Splunk is a software company that developed the product Splunk software for searching, monitoring, and analyzing machine-generated big data, via a web-style interface. Splunk captures, indexes and correlates real-time data in a searchable repository from which it can generate graphs, reports, alerts, dashboards and visualizations.

The Spring Framework is an open source application framework and inversion of control container for the Java platform. The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE platform.

IoC is also known as dependency injection (DI). In traditional programming, the flow of the business logic is determined by objects that are statically assigned to one another. With inversion of control, the flow depends on the object graph that is instantiated by the assembler and is made possible by object interactions being defined through abstractions. The binding process is achieved through dependency injection, although some argue that the use of a service locator also provides inversion of control.

The Spring web MVC framework provides model-view-controller architecture and ready components that can be used to develop flexible and loosely coupled web applications. The MVC framework is designed around a DispatcherServlet that dispatches requests to handlers, with configurable handler mappings, view resolution, locale, time zone and theme resolution as well as support for uploading files. The default handler is based on the @Controller and @RequestMapping annotations, offering a wide range of flexible handling methods.

Spring Security is a Java/Java EE framework that focuses on providing both authentication and authorization for enterprise applications. It is the de-facto standard for securing Spring-based applications.

A set period of time in an Agile software development project during which specific work has to be completed and made ready for review.

Sprite Kit provides a graphics rendering and animation infrastructure that one can use to animate arbitrary textured images, or sprites. Sprite Kit uses a traditional rendering loop where the contents of each frame are processed before the frame is rendered. A game determines the contents of the scene and how those contents change in each frame. Sprite Kit does the work to render frames of animation efficiently using the graphics hardware. Sprite Kit is optimized so that the positions of sprites can be changed arbitrarily in each frame of animation.

Sprite sheet is an image containing a combination of distinct images used in an application and using them whereever required by defining the position of the image in pixels. This technique is used to reduce the memory storage space consumed by images within an application.
