Boston Computer Society
The Boston Computer Society (BCS) was an organization of personal computer users, based in Boston, Massachusetts, United States , that ran from 1977 to 1996. At one point, it was the largest such group in the world, with regular user group meetings, many publications, permanent offices in Boston, and hosting major product announcements, including the East Coast release of the Apple Macintosh in 1984.

Cache Placement Policies
Cache is a memory which holds the recently utilized data by the processor. A block of memory cannot be placed randomly in the cache and is restricted to a single cache line by the “Placement Policy”. In other words, Placement Policy determines where a particular memory block can be placed when it goes into the cache. There are three different policies available for placement of a memory block in the cache.

Challenges According to the ‘7Vs’ of Big Data
Big Data has challenges that sometimes are the same as its own characteristics. These characteristics are known as the Vs. The researchers describe ‘7Vs’ that they have found and are the most used and more related to general data used in Big Data, including an explanation and challenges that exist according to them. Some of them have different subtypes according to the differences detected in the literature and working with them. Some authors create a different V for similar purposes, and here, the researcher gather them into one due to the similarities.

Chaotic Image Encryption
Chaos is the characteristic of a system whose current state is guaranteed to be highly sensitive to the previous state (spatial chaos), the initial conditions (temporal chaos), or both (spatio-temporal chaos). Such a sensitivity makes the output or the behavior of a chaotic system difficult to predict. Chaos theory justifies and formulates the apparent disorder of chaotic systems on the basis of orderly patterns, structured feedback loops, iterative repetitions, self-organization, self-similarity, fractals, etc. Chaotic maps, attractors, and sequences all refer to the mathematical structures used for this formulation. Chaotic systems, maps, attractors, and sequences have been of great interest to the research community. They have been used for security purposes in a broad variety of applications ranging from smart grids to communication systems. Especially, chaotic encryption has been used for encrypting a variety of content types in addition to images.

Clipboard (Computing)
The clipboard is a buffer that some operating systems provide for short-term storage and transfer within and between application programs. The clipboard is usually temporary and unnamed, and its contents reside in the computer's RAM. The clipboard provides an application programming interface by which programs can specify cut, copy and paste operations. It is left to the program to define methods for the user to command these operations, which may include keybindings and menu selections. When an element is copied or cut, the clipboard must store enough information to enable a sensible result no matter where the element is pasted. Application programs may extend the clipboard functions that the operating system provides. A clipboard manager may give the user additional control over the clipboard. Specific clipboard semantics vary among operating systems, can also vary between versions of the same system, and can sometimes be changed by programs and by user preferences. Windows, Linux and macOS support a single clipboard transaction.

Cognitive Load Theory and eLearning of Crafts
Craft education and training are important for preserving cultural heritage and fostering artisanal skills. Craft education and training are challenging since they introduce learners to a multifaceted world, where they must acquire skills, knowledge, and appreciation for cultural heritage. Balancing these learning objectives is a cognitive challenge.

Conceptual Modelling in Operational Simulation of Logistics
Logistics problems involve a large number of complexities, which makes the development of models challenging. While computer simulation models are developed for addressing complexities, it is essential to ensure that the necessary operational behaviours are captured, and that the architecture of the model is suitable to represent them. The early stage of simulation modelling, known as conceptual modelling (CM), is thus dependent on successfully extracting tacit operational knowledge and avoiding misunderstanding between the client (customer of the model) and simulation analyst.

Conservation and Restoration OpenLab
Open laboratories (OpenLabs) in Cultural Heritage institutions are an effective way to provide visibility into the behind-the-scenes processes and promote documentation data collected and produced by domain specialists. Cultural Heritage (CH) institutions have been adopting new practices to improve their services and meet the preferences and needs of potential audiences. One such practice is the transformation of conservation and restoration (CnR) laboratories into OpenLabs, which allow visitors to see the various processes that take place “behind the scenes” .
