PNaCl
Google Native Client (NaCl) is a discontinued sandbox (computer security), sandboxing technology for running either a subset of Intel x86, ARM architecture, ARM, or MIPS architecture, MIPS native code, or a portable executable, in a sandbox. It allows safely running native code from a web browser, independent of the user operating system, allowing web apps to run at near-native speeds, which aligns with Google's plans for ChromeOS. It may also be used for securing browser plug-in (computing), plugins, and parts of other applications or full applications such as ZeroVM. To demonstrate the readiness of the technology, on 9 December 2011, Google announced the availability of several new Chrome-only versions of videogame, games known for their rich and Central processing unit, processor-intensive computer graphics, graphics, including ''Bastion (video game), Bastion'' (no longer supported on the Chrome Web Store). NaCl runs hardware acceleration (computing), hardware-accelerated 3D g ...

WebAssembly
WebAssembly (sometimes abbreviated Wasm) defines a portable binary-code format and a corresponding text format for executable programs as well as software interfaces for facilitating interactions between such programs and their host environment. The main goal of WebAssembly is to enable high-performance applications on web pages, "but it does not make any Web-specific assumptions or provide Web-specific features, so it can be employed in other environments as well." It is an open standard and aims to support any language on any operating system, and in practice all of the most popular languages already have at least some level of support. Announced in and first released in , WebAssembly became a World Wide Web Consortium recommendation on 5 December 2019 and it received the ''Programming Languages Software Award'' from ACM SIGPLAN in 2021. The World Wide Web Consortium (W3C) maintains the standard with contributions from Mozilla, Microsoft, Google, Apple, Fastly, Intel, an ...

ZeroVM
ZeroVM is an open source light-weight virtualization and sandboxing technology. It virtualizes a single process using the Google Native Client platform. Since only a single process is virtualized (instead of a full operating system), the startup overhead is in the order of 5 ms. Sandboxing ZeroVM creates a sandbox around a single process, using technology based on Google Native Client (NaCl). The sandbox ensures that the application executed cannot access data in the host operating system, so it is safe to execute untrusted code. The programs executed in ZeroVM must first be cross-compiled to the NaCl platform. ZeroVM can only execute NaCl code compiled for the x86-64 platform, not the portable Native Client (PNaCl) format. Code executed in ZeroVM cannot call normal system calls and initially cannot interact with the host environment. All communication with the outside world takes place over ''channels'', which must be declared before the program starts. Outside the sandbox, ...

Web App
A web application (or web app) is application software that is accessed using a web browser. Web applications are delivered on the World Wide Web to users with an active network connection. History In earlier computing models like client-server, the processing load for the application was shared between code on the server and code installed on each client locally. In other words, an application had its own pre-compiled client program which served as its user interface and had to be separately installed on each user's personal computer. An upgrade to the server-side code of the application would typically also require an upgrade to the client-side code installed on each user workstation, adding to the support cost and decreasing productivity. In addition, both the client and server components of the application were usually tightly bound to a particular computer architecture and operating system and porting them to others was often prohibitively expensive for all but the larges ...

ActiveX
ActiveX is a deprecated software framework created by Microsoft that adapts its earlier Component Object Model (COM) and Object Linking and Embedding (OLE) technologies for content downloaded from a network, particularly from the World Wide Web. Microsoft introduced ActiveX in 1996. In principle, ActiveX is not dependent on Microsoft Windows operating systems, but in practice, most ActiveX controls only run on Windows. Most also require the client to be running on an x86-based computer because ActiveX controls contain compiled code. ActiveX is still supported as of Windows 10 through Internet Explorer 11, while ActiveX is not supported in their default web browser Microsoft Edge (which has a different, incompatible extension system, as it is based on Google's Chromium project). ActiveX controls ActiveX was one of the major technologies used in component-based software engineering. Compared with JavaBeans, ActiveX supports more programming languages, but JavaBeans supports m ...

Ahead-of-time Compilation
In computer science, ahead-of-time compilation (AOT compilation) is the act of compiling an (often) higher-level programming language into an (often) lower-level language before execution of a program, usually at build-time, to reduce the amount of work needed to be performed at run time. Most often, It is associated with the act of compiling a higher-level programming language such as C or C++, or an intermediate representation such as Java bytecode or .NET Framework Common Intermediate Language (CIL) code, into a native (system-dependent) machine code so that the resulting binary file can execute natively, just like a ''standard'' native compiler. When being used in this specific context, it's often seen as an opposite of just-in-time (JIT) compiling. Speaking more generally, the target languages of an AOT compilation are not necessarily specific to native machine code but are defined rather arbitrarily. Some academic papers use this word to mean the act of compiling the Jav ...

Computer Mouse
A computer mouse (plural mice, sometimes mouses) is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface of a computer. The first public demonstration of a mouse controlling a computer system was in 1968. Mice originally used two separate wheels to track movement across a surface: one in the X-dimension and one in the Y. Later, the standard design shifted to utilize a ball rolling on a surface to detect motion. Most modern mice use optical sensors that have no moving parts. Though originally all mice were connected to a computer by a cable, many modern mice are cordless, relying on short-range radio communication with the connected system. In addition to moving a cursor, computer mice have one or more buttons to allow operations such as the selection of a menu item on a display. Mice often also featur ...

Dynamic Loading
Dynamic loading is a mechanism by which a computer program can, at run time, load a library (or other binary) into memory, retrieve the addresses of functions and variables contained in the library, execute those functions or access those variables, and unload the library from memory. It is one of the 3 mechanisms by which a computer program can use some other software; the other two are static linking and dynamic linking. Unlike static linking and dynamic linking, dynamic loading allows a computer program to start up in the absence of these libraries, to discover available libraries, and to potentially gain additional functionality. History Dynamic loading was a common technique for IBM's operating systems for System/360 such as OS/360, particularly for I/O subroutines, and for COBOL and PL/I runtime libraries, and continues to be used in IBM's operating systems for z/Architecture, such as z/OS. As far as the application programmer is concerned, the loading is larg ...

OpenGL ES
OpenGL for Embedded Systems (OpenGL ES or GLES) is a subset of the OpenGL computer graphics rendering application programming interface (API) for rendering 2D and 3D computer graphics such as those used by video games, typically hardware-accelerated using a graphics processing unit (GPU). It is designed for embedded systems like smartphones, tablet computers, video game consoles and PDAs. OpenGL ES is the "most widely deployed 3D graphics API in history". The API is cross-language and multi-platform. The GLU library and the original GLUT are not available for OpenGL ES, freeglut however, supports it. OpenGL ES is managed by the non-profit technology consortium Khronos Group. Vulkan, a next-generation API from Khronos, is made for simpler high performance drivers for mobile and desktop devices. Versions Several versions of the OpenGL ES specification now exist. OpenGL ES 1.0 is drawn up against the OpenGL 1.3 specification, OpenGL ES 1.1 is defined relative to the OpenGL ...

Hardware Acceleration (computing)
Hardware acceleration is the use of computer hardware designed to perform specific functions more efficiently when compared to software running on a general-purpose central processing unit (CPU). Any transformation of data that can be calculated in software running on a generic CPU can also be calculated in custom-made hardware, or in some mix of both. To perform computing tasks more quickly (or better in some other way), generally one can invest time and money in improving the software, improving the hardware, or both. There are various approaches with advantages and disadvantages in terms of decreased latency, increased throughput and reduced energy consumption. Typical advantages of focusing on software may include more rapid development, lower non-recurring engineering costs, heightened portability, and ease of updating features or patching bugs, at the cost of overhead to compute general operations. Advantages of focusing on hardware may include speedup, reduced po ...

Chrome Web Store
Chrome Web Store is Google's online store for its Chrome web browser. As of 2019, Chrome Web Store hosts about 190,000 extensions and web apps. History Chrome Web Store was publicly unveiled in December 2010, and was opened on February 11, 2011, with the release of Google Chrome 9.0. A year later it was redesigned to "catalyze a big increase in traffic, across downloads, users, and total number of apps". As of June 2012, there were 750 million total installs of content hosted on Chrome Web Store. Some extension developers have sold their extensions to third-parties who then incorporated adware. In 2014, Google removed two such extensions from Chrome Web Store after many users complained about unwanted pop-up ads. The following year, Google acknowledged that about five percent of visits to its own websites had been altered by extensions with adware. Malware Malware remains a problem on Chrome Web Store. In January 2018, security researchers found four malicious extensions ...

Bastion (video Game)
''Bastion'' is an action role-playing video game developed by independent developer Supergiant Games and originally published in 2011 by Warner Bros. Interactive Entertainment. In the game, the player controls "the Kid" as he moves through floating, fantasy-themed environments and fights enemies of various types. It features a dynamic voiceover from a narrator (Logan Cunningham), and is presented as a two-dimensional game with an isometric camera and a hand-painted, colorful art style. ''Bastion''s story follows the Kid as he collects special shards of rock to power a structure, the Bastion, in the wake of an apocalyptic Calamity. The game was built over the course of two years by a team of seven people split between San Jose and New York City. They debuted the game at the September 2010 Penny Arcade Expo, and it went on to be nominated for awards at the 2011 Independent Games Festival and win awards at the Electronic Entertainment Expo prior to release. ''Bastion'' was publ ...
