XEDIT
XEDIT is a visual editor for VM/CMS using block mode IBM 3270 terminals. (Line-mode terminals are also supported.) XEDIT is much more line-oriented than modern PC and Unix editors. For example, XEDIT supports automatic line numbers, and many of the commands operate on blocks of lines. A pair of features allows selective line and column editing. The ALL command, for example, hides all lines not matching the described pattern, and the COL (Column) command allows hiding those columns not specified. Hence changing, for example, the word NO as it appears only in columns 24 thru 28, to YES, and only on lines with the word FLEXIBLE, is doable. Another feature is a command line which allows the user to type arbitrary editor commands. Because IBM 3270 terminals do not transmit data to the computer until certain special keys are pressed [such as , a program function key (PFK), or a program access key (PAK), XEDIT is less interactive than many PC and Unix editors. For example, continuous spell-checking as the user types is problematic.

XCore Architecture
The XCore Architecture is a 32-bit RISC microprocessor architecture designed by XMOS. The architecture is designed to be used in multi-core processors for embedded systems. Each XCore executes up to eight concurrent threads, each thread having its own register set, and the architecture directly supports inter-thread and inter-core communication and various forms of thread scheduling. Two versions of the XCore architecture exist: the XS1 architecture and the XS2 architecture. Processors with the XS1 architecture include the XCore XS1-G4 and XCore XS1-L1. Processors with the XS2 architecture include xCORE-200. The architecture encodes instructions compactly, using 16 bits for frequently used instructions (with up to three operands) and 32 bits for less frequently used instructions (with up to 6 operands). Almost all instructions execute in a single cycle, and the architecture is event-driven in order to decouple the timings that a program needs to make from the execution speed of the program. A program will normally perform its computations and then wait for an event (e.g. a message, time, or external I/O event) before continuing.

XC (Programming Language)
In computers, XC is a programming language for real-time embedded parallel processors, targeted at the XMOS XCore processor architecture. XC is an imperative language, based on the features for parallelism and communication in occam, and the syntax and sequential features of C. It provides primitive features that correspond to the various architectural resources provided, namely: channel ends, locks, ports and timers. In combination with XCore processors, XC is used to build embedded systems with levels of I/O, real-time performance and computational ability usually attributed to field-programmable gate arrays (FPGAs) or application-specific integrated circuit (ASIC) devices.

XBRL GL
The XBRL Global Ledger Taxonomy Framework (XBRL GL) is a holistic and generic XML and XBRL-based representation of the detailed data that can be found in accounting and operational systems, and is meant to be the bridge from transactional standards to reporting standards, integrating the Business Reporting Supply Chain. XBRL GL is developed by the XBRL GL Working Group of XBRL International. XBRL GL can be used by Computer programs for information interchange of accounting General ledger balances (summarized information) as well as complete accounting ledgers (payables, receivables, inventory, payroll, order entry, purchasing, banking) supporting object oriented accounting, quantity accounting and transparency support. The instance documents (XML files) can also be viewed in Web browsers using XSL or programmatically; it can also be carried in Inline XBRL. XBRL is designed to standardize the data, processes and rules of Business Reporting as a whole, although most implementations focus on financial reporting. XBRL GL can support the detail and integrate to all manners of reporting, financial, tax, sustainability, statistics and otherwise, and carry both quantitative and qualitative information.

XBP1 Modulates the Aging Cardiorenal System
X-box binding protein 1 (XBP1) is a unique basic-region leucine zipper (bZIP) transcription factor. Over recent years, the powerful biological functions of XBP1 in oxidative stress have been gradually revealed. When the redox balance remains undisturbed, oxidative stress plays a role in physiological adaptations and signal transduction. However, during the aging process, increased cellular senescence and reduced levels of endogenous antioxidants cause an oxidative imbalance in the cardiorenal system.

Xbox One System Software
The Xbox One system software, sometimes called the Xbox OS, or Xbox Dashboard (when a person is referring to software updates), is the operating system developed exclusively for the Xbox One consoles. It is a Microsoft Windows-based operating system using the Hyper-V virtual machine monitor and contains separate operating systems for games and applications that can run on the console. It is located on the internal HDD for day-to-day usage, while also being duplicated on the internal NAND storage of the console for recovery purposes and factory reset functionality. The Xbox One allows users to download applications that add to the functionality of the dashboard. From June 2014 onwards, entertainment apps no longer required the user to be signed into a valid Xbox Live Gold account in order to use the features advertised for the given app. Since launch, Microsoft has been updating the OS monthly, with updates downloaded from the Xbox Live service directly to the Xbox One and subsequently installed, or by using offline recovery images downloaded via a PC. In November 2015, a major system update known as the New Xbox One Experience was released, which brought very significant changes to the design and functionality of the system. The Windows 10-based Core had replaced the Windows 8-based one in this update, and the new system is sometimes referred to as "Windows 10 on Xbox One".

Xbox 360 System Software
The Xbox 360 system software or the Xbox 360 Dashboard is the updateable software and operating system for the Xbox 360. It formerly resided in a 16 MB file system. However, starting with the NXE Update, more storage became a requirement, rectified by either having a Hard Drive installed, or one of the later revisions of the console with adequate flash storage embedded within the console. The system software has access to a maximum of 32 MB of the system's Random Access Memory. The updates can be downloaded from the Xbox Live service directly to the Xbox 360 and subsequently installed. Microsoft has also provided the ability to download system software updates from their respective official Xbox website to their PCs and then storage media, from which the update can be installed to the system. The Xbox 360 game system allows users to download applications that add to the functionality of the dashboard. Most apps required the user to be signed into a valid Xbox Live Gold account in order to use the features advertised for the given app. But as of the 2.0.16756.0 update, most apps do not require an Xbox Live Gold Subscription to access them, although the app may have its own subscription to be able to use it. With the exception of a few early apps, Microsoft has added partners to develop apps for the Xbox 360 system since the New Xbox Experience (NXE) Dashboard update in 2008. Following the success of Xbox One preview program launched in 2014, in March 2015, Microsoft announced the Xbox 360 preview program to the public.

XBMCbuntu
Kodi (formerly XBMC) is a free and open-source media player software application developed by the XBMC Foundation, a non-profit technology consortium. Kodi is available for multiple operating systems and hardware platforms, with a software 10-foot user interface for use with televisions and remote controls. It allows users to play and view most streaming media, such as videos, music, podcasts, and videos from the Internet, as well as all common digital media files from local and network storage media. It is a multi-platform home-theater PC (HTPC) application. Kodi is customizable: skins can change its appearance, and plug-ins allow users to access streaming media content via online services such as Amazon Prime Instant Video, Crackle, Pandora Internet Radio, Rhapsody, Spotify, and YouTube. The later versions also have a personal video-recorder (PVR) graphical front end for receiving live television with electronic program guide (EPG) and high-definition digital video recorder (DVR) support. The software was created in 2002 as an independently developed homebrew media player application named Xbox Media Player for the first-generation Xbox game console, changing its name in 2004 to Xbox Media Center (abbreviated as XBMC, which was adopted as the official name in 2008) and was later made available under the name XBMC as a native application for Android, Linux, BSD, macOS, iOS/tvOS, and Microsoft Windows-based operating systems. Because of its open source and cross-platform nature, with its core code written in C++, modified versions of Kodi-XBMC together with JeOS have been used as a software appliance suite or software framework in a variety of devices, including smart TVs, set-top boxes, digital signage, hotel television systems, network connected media players and embedded systems based on armhf platforms like Raspberry Pi. Derivative applications such as MediaPortal and Plex have been spun off from XBMC or Kodi, as well as just enough operating systems like LibreELEC. Kodi has attracted negative attention due to the availability of third-party plug-ins for the software that facilitate unauthorized access to copyrighted media content, as well as "fully loaded" digital media players that are pre-loaded with such add-ons; The XBMC Foundation has not endorsed any of these uses, and has taken steps to disassociate the Kodi project from these add-ons, including threatening legal action against those using its trademarks to promote them.
