Completion (Algebra)
In abstract algebra, a completion is any of several related functors on rings and modules that result in complete topological rings and modules. Completion is similar to localization, and together they are among the most basic tools in analysing commutative rings. Complete commutative rings have a simpler structure than general ones, and Hensel's lemma applies to them. In algebraic geometry, a completion of a ring of functions R on a space X concentrates on a formal neighborhood of a point of X: heuristically, this is a neighborhood so small that all Taylor series centered at the point are convergent. An algebraic completion is constructed in a manner analogous to completion of a metric space with Cauchy sequences, and agrees with it in case R has a metric given by a non-Archimedean absolute value.

Cinnamon
Cinnamon is a free and open-source desktop environment for the X Window System that derives from GNOME 3 but follows traditional desktop metaphor conventions. Cinnamon is the principal desktop environment of the Linux Mint distribution but is available as an optional desktop for other Linux distributions and other Unix-like operating systems as well. The development of Cinnamon began as a reaction to the April 2011 release of GNOME 3 in which the conventional desktop metaphor of GNOME 2 was abandoned in favor of GNOME Shell. Following several attempts to extend GNOME 3 such that it would suit the Linux Mint design goals, the Mint developers forked several GNOME 3 components to build an independent desktop environment. Separation from GNOME was completed in Cinnamon 2.0, which was released in October 2013. Applets and desklets are no longer compatible with GNOME 3. As the distinguishing factor of Linux Mint, Cinnamon has generally received favorable coverage by the press, in particular for its ease-of-use and gentle learning curve. With respect to its conservative design model, Cinnamon is similar to the XFCE and GNOME 2 (MATE and GNOME Flashback/Classic) desktop environments.

Zone File
A Domain Name System (DNS) zone file is a text file that describes a DNS zone. A DNS zone is a subset, often a single domain, of the hierarchical domain name structure of the DNS. The zone file contains mappings between domain names and IP addresses and other resources, organized in the form of text representations of resource records (RR). A zone file may be either a DNS master file, authoritatively describing a zone, or it may be used to list the contents of a DNS cache.

Local Search (Internet)
Local search is the use of specialized Internet search engines that allow users to submit geographically constrained searches against a structured database of local business listings. Typical local search queries include not only information about "what" the site visitor is searching for (such as keywords, a business category, or the name of a consumer product) but also "where" information, such as a street address, city name, postal code, or geographic coordinates like latitude and longitude. Examples of local searches include "Hong Kong hotels", "Manhattan restaurants", and "Dublin car rental". Local searches exhibit explicit or implicit local intent. A search that includes a location modifier, such as "Bellevue, WA" or "14th arrondissement", is an explicit local search. A search that references a product or service that is typically consumed locally, such as "restaurant" or "nail salon", is an implicit local search. Local searches on Google Search typically return organic results prefaced with a 'local 3-pack', a list of three local results. More local results can be obtained by clicking on “more places” under the 3-pack. The list of results one obtains is also called the Local Finder. Search engines and directories are primarily supported by advertising from businesses that wish to be prominently featured when users search for specific products and services in specific locations. Google for instance, has developed local inventory ads and features ads in the local pack. Local search advertising can be highly effective because it allows ads to be targeted very precisely to the search terms and location provided by the user.

Sugar
Sugar is a free and open-source desktop environment designed for interactive learning by children. Copyright by SugarLabs. Developed as part of the One Laptop per Child (OLPC) project, Sugar was the default interface on OLPC XO-1 laptop computers. The OLPC XO-1.5 and later provided the option of either the Gnome or Sugar interfaces. Sugar is available as a Live CD, as Live USB, and a package installable through several Linux distributions. It can run in a Linux virtual machine under Windows and Mac OS. Unlike most other desktop environments, Sugar does not use the "desktop", "folder" and "window" metaphors. Instead, Sugar's default full-screen activities require users to focus on only one program at a time. Sugar implements a journal which automatically saves the user's running program session and allows them to later use an interface to pull up their past works by date, an activity used, or file type.

Digital Escape Rooms in STEM Education
The traditional lecture-based model of teaching and learning has led to the exploration of innovative approaches including digital escape rooms. Digital escape rooms offer an immersive and engaging experience that promotes critical thinking, problem-solving, and teamwork, making them a unique opportunity to address the challenges of science, technology, engineering, and math (STEM) education, which is often perceived as difficult, boring, and intimidating.
