SHIFT (DOS Command)
This research presents a list of commands used by DOS operating systems, especially as used on x86-based IBM PC compatibles (PCs). Other DOS operating systems are not part of the scope of this list. In DOS, many standard system commands were provided for common tasks such as listing files on a disk or moving files. Some commands were built into the command interpreter, others existed as external commands on disk. Over the several generations of DOS, commands were added for the additional functions of the operating system. In the current Microsoft Windows operating system, a text-mode command prompt window, cmd.exe, can still be used.

Batch File
A batch file is a script file in DOS, OS/2 and Microsoft Windows. It consists of a series of commands to be executed by the command-line interpreter, stored in a plain text file. A batch file may contain any command the interpreter accepts interactively and use constructs that enable conditional branching and looping within the batch file, such as IF, FOR, and GOTO labels. The term "batch" is from batch processing, meaning "non-interactive execution", though a batch file may not process a batch of multiple data. Similar to Job Control Language (JCL), DCL and other systems on mainframe and minicomputer systems, batch files were added to ease the work required for certain regular tasks by allowing the user to set up a script to automate them. When a batch file is run, the shell program (usually COMMAND.COM or cmd.exe) reads the file and executes its commands, normally line-by-line. Unix-like operating systems, such as Linux, have a similar, but more flexible, type of file called a shell script. The filename extension .bat is used in DOS and Windows. Windows NT and OS/2 also added .cmd. Batch files for other environments may have different extensions, e.g., .btm in 4DOS, 4OS2 and 4NT related shells. The detailed handling of batch files has changed significantly between versions. Some of the detail in this article applies to all batch files, while other details apply only to certain versions.

Here
Here Technologies (trading as HERE) is a company that provides mapping and location data and related services to individuals and companies. It is majority-owned by a consortium of German automotive companies (namely Audi, BMW, and Daimler), whilst other companies also own minority stakes. Its roots date back to U.S.-based Navteq in 1985, which was acquired by Finland-based Nokia in 2007. Here is currently based in Amsterdam. Here captures location content such as road networks, buildings, parks and traffic patterns. It then sells or licenses that mapping content, along with map related navigation and location services to other businesses such as Alpine, Garmin, BMW, Oracle and Amazon.com. In addition, Here provides platform services to smartphones. It provides location services through its own Here applications, and also for GIS and government clients and other providers, such as Bing, Facebook and Yahoo! Maps. Here has maps of nearly 200 countries, offers voice guided navigation in 94 countries, provides live traffic information in 33 countries and has indoor maps available for about 49,000 unique buildings in 45 countries. The company is also working on self-driving technology. HERE Technologies India Private Limited is recognized among India's Best Companies to Work For 2019 ranking at place #33 and among India's Best Workplaces for Women 2019 (Top 25) from "Great Place to Work". HERE is once again the highest-ranked location platform vendor in the index. HERE has cemented its leadership position thanks to the continuous improvements it has made to its core Open Location Platform, doubling down on its efforts for developers, and a string of new initiatives including a renewed focus on data privacy.

Open Science Data
Open science data or Open Research Data is a type of open data focused on publishing observations and results of scientific activities available for anyone to analyze and reuse. A major purpose of the drive for open data is to allow the verification of scientific claims, by allowing others to look at the reproducibility of results, and to allow data from many sources to be integrated to give new knowledge. While the idea of open science data has been actively promoted since the 1950s, the rise of the Internet has significantly lowered the cost and time required to publish or obtain data.

OpenMP
OpenMP (Open Multi-Processing) is an application programming interface (API) that supports multi-platform shared-memory multiprocessing programming in C, C++, and Fortran, on many platforms, instruction-set architectures and operating systems, including Solaris, AIX, FreeBSD, HP-UX, Linux, macOS, and Windows. It consists of a set of compiler directives, library routines, and environment variables that influence run-time behavior. OpenMP is managed by the nonprofit technology consortium OpenMP Architecture Review Board (or OpenMP ARB), jointly defined by a broad swath of leading computer hardware and software vendors, including Arm, AMD, IBM, Intel, Cray, HP, Fujitsu, Nvidia, NEC, Red Hat, Texas Instruments, and Oracle Corporation. OpenMP uses a portable, scalable model that gives programmers a simple and flexible interface for developing parallel applications for platforms ranging from the standard desktop computer to the supercomputer. An application built with the hybrid model of parallel programming can run on a computer cluster using both OpenMP and Message Passing Interface (MPI), such that OpenMP is used for parallelism within a (multi-core) node while MPI is used for parallelism between nodes. There have also been efforts to run OpenMP on software distributed shared memory systems, to translate OpenMP into MPI and to extend OpenMP for non-shared memory systems.

Life Quality Index
The Life Quality Index (LQI) is a calibrated compound social indicator of human welfare that reflects the expected length of life in good health and enhancement of the quality of life through access to income. The Life Quality Index combines two primary social indicators: the expectancy of healthy life at birth, E, and the real gross domestic product per person, G, corrected for purchasing power parity as appropriate. Both are widely available and accurate statistics.

Gendered Associations of Pink and Blue
The colors pink and blue are associated with girls and boys respectively, in the United States, the United Kingdom and some other European countries. Originating as a trend in the mid-19th century and applying primarily to clothing, gendered associations with pink and blue became more widespread from the 1950s onward. Since the 1990s, these gendered associations have also increasingly applied to toys as well, especially in the case of pink toys for girls. Despite popular belief—including from various academic and popular sources—a reported "pink-blue reversal", wherein the gendered associations of both colors were "flipped" sometime during the 20th century, most likely never occurred, and instead is likely to have been a misunderstanding of earlier reporting.

Petya and NotPetya
Petya is a family of encrypting malware that was first discovered in 2016. The malware targets Microsoft Windows–based systems, infecting the master boot record to execute a payload that encrypts a hard drive's file system table and prevents Windows from booting. It subsequently demands that the user make a payment in Bitcoin in order to regain access to the system. Variants of Petya were first seen in March 2016, which propagated via infected e-mail attachments. In June 2017, a new variant of Petya was used for a global cyberattack, primarily targeting Ukraine . The new variant propagates via the EternalBlue exploit, which is generally believed to have been developed by the United States . National Security Agency (NSA), and was used earlier in the year by the WannaCry ransomware. Kaspersky Lab referred to this new version as NotPetya to distinguish it from the 2016 variants, due to these differences in operation. In addition, although it purports to be ransomware, this variant was modified so that it is unable to actually revert its own changes. The NotPetya attacks have been blamed on the Russian government, specifically the Sandworm hacking group within the GRU Russian military intelligence organization, by security researchers, Google, and several governments.
