Trojan Source
Trojan Source is a Vulnerability (computing), software vulnerability that abuses Unicode's bidirectional characters to display source code differently than the actual execution of the source code. The exploit utilizes how writing scripts of different reading directions are displayed and encoded on computers. It was discovered by Nicholas Boucher and Ross Anderson at University of Cambridge, Cambridge University in late 2021. Background Unicode is an encoding standard for representing text, symbols, and glyphs. Unicode is the most dominant encoding on computers, used in over 98% of websites . It supports many languages, and because of this, it must support different methods of writing text. This requires support for both Left to left-to-right languages, such as English and Russian, and Right-to-left script, right-to-left languages, such as Hebrew language, Hebrew and Arabic. Since Unicode aims to enable using more than one writing system, it must be able to mix scripts with dif ...

Unicode
Unicode or ''The Unicode Standard'' or TUS is a character encoding standard maintained by the Unicode Consortium designed to support the use of text in all of the world's writing systems that can be digitized. Version 16.0 defines 154,998 Character (computing), characters and 168 script (Unicode), scripts used in various ordinary, literary, academic, and technical contexts. Unicode has largely supplanted the previous environment of a myriad of incompatible character sets used within different locales and on different computer architectures. The entire repertoire of these sets, plus many additional characters, were merged into the single Unicode set. Unicode is used to encode the vast majority of text on the Internet, including most web pages, and relevant Unicode support has become a common consideration in contemporary software development. Unicode is ultimately capable of encoding more than 1.1 million characters. The Unicode character repertoire is synchronized with Univers ...

JavaScript
JavaScript (), often abbreviated as JS, is a programming language and core technology of the World Wide Web, alongside HTML and CSS. Ninety-nine percent of websites use JavaScript on the client side for webpage behavior. Web browsers have a dedicated JavaScript engine that executes the client code. These engines are also utilized in some servers and a variety of apps. The most popular runtime system for non-browser usage is Node.js. JavaScript is a high-level, often just-in-time–compiled language that conforms to the ECMAScript standard. It has dynamic typing, prototype-based object-orientation, and first-class functions. It is multi-paradigm, supporting event-driven, functional, and imperative programming styles. It has application programming interfaces (APIs) for working with text, dates, regular expressions, standard data structures, and the Document Object Model (DOM). The ECMAScript standard does not include any input/output (I/O), such as netwo ...

2021 In Computing
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural numbe ...

Unicode Consortium
The Unicode Consortium (legally Unicode, Inc.) is a 501(c)(3) non-profit organization incorporated and based in Mountain View, California, U.S. Its primary purpose is to maintain and publish the Unicode Standard which was developed with the intention of replacing existing character encoding schemes that are limited in size and scope, and are incompatible with multilingual environments. Unicode's success at unifying character sets has led to its widespread adoption in the internationalization and localization of software. The standard has been implemented in many technologies, including XML, the Java programming language, Swift, and modern operating systems. Members are usually but not limited to computer software and hardware companies with an interest in text-processing standards, including Adobe, Apple, the Bangladesh Computer Council, Emojipedia, Facebook, Google, IBM, Microsoft, the Omani Ministry of Endowments and Religious Affairs, Monotype Imaging, Netflix, Sales ...

Common Vulnerabilities And Exposures
The Common Vulnerabilities and Exposures (CVE) system, originally Common Vulnerability Enumeration, provides a reference method for publicly known information security, information-security vulnerability (computing), vulnerabilities and exposures. The United States' Homeland Security Systems Engineering and Development Institute FFRDC, operated by The MITRE Corporation, maintains the system, with funding from the US National Cyber Security Division of the US Department of Homeland Security. The system was officially launched for the public in September 1999. The Security Content Automation Protocol uses CVE, and CVE IDs are listed on MITRE's system as well as the basis for the US National Vulnerability Database. CVE identifiers MITRE Corporation's documentation defines CVE Identifiers (also called "CVE names", "CVE numbers", "CVE-IDs", and "CVEs") as unique, common identifiers for publicly known information-security vulnerabilities in publicly released software packages. Historic ...

Vim (text Editor)
Vim (;
: "Vim is pronounced as one word, like Jim, not vi-ai-em. It's written with a capital, since it's a name, again like Jim."
''vi improved'') is a free and open-source, screen-based text editor program. It is an improved Clone (computing), clone of Bill Joy's vi (text editor), vi. Vim's author, Bram Moolenaar, derived Vim from a port of the Stevie (text editor), Stevie editor for Amiga and released a version to the public in 1991. Vim is designed for use both from a command-line interface and as a standalone application in a graphical user interface. Since its release for the Amiga, cross-platform development has made it available on #Availability, many other systems. In 2018, it was voted the most popular editor amongst ''Linux Journal'' readers; in 2015 the Stack Overflow developer survey found it to be the third most popular text edit ...

Notepad++
Notepad++ (sometimes npp or NPP) is a text and source code editor for use with Microsoft Windows. It supports tabbed editing, which allows working with multiple open files in one window. The program's name comes from the C postfix increment operator. Notepad++ is released as free and open-source software under a GNU General Public License (GPL) 3.0 or later. At first, the project was hosted on the SourceForge software repository (2003–2010), from where it was downloaded over 28 million times, and twice won the SourceForge Community Choice Award for Best Developer Tool. Then, the project moved to TuxFamily (2010–2015), and then to GitHub (2015–present). Notepad++ uses the Scintilla editor component. History Notepad++ development began in September 2003 by Don Ho, a former Paris Diderot University computer science student.

Rust (programming Language)
Rust is a General-purpose programming language, general-purpose programming language emphasizing Computer performance, performance, type safety, and Concurrency (computer science), concurrency. It enforces memory safety, meaning that all Reference (computer science), references point to valid memory. It does so without a conventional Garbage collection (computer science), garbage collector; instead, memory safety errors and data races are prevented by the "borrow checker", which tracks the object lifetime of references Compiler, at compile time. Rust does not enforce a programming paradigm, but was influenced by ideas from functional programming, including Immutable object, immutability, higher-order functions, algebraic data types, and pattern matching. It also supports object-oriented programming via structs, Enumerated type, enums, traits, and methods. It is popular for systems programming. Software developer Graydon Hoare created Rust as a personal project while working at ...
