Qt Version History
The latest version of Qt is 6.5 released on 3 April 2023. Also still supported, for commercial users, are 5.15 LTS, released on 26 May 2020, and 6.2 LTS, released on 30 September 2021 – long-term support (LTS) versions are generally supported for three years, with a commercial license, while 5.15 support was extended to five years, so it is supported for longer or until 26 May 2025. In addition the KDE project provides unofficial support for, at least, Qt 5.15, i.e. not just for commercial users. A regular release only receives patch releases during the first 6 months, until the next feature release is out, while an LTS release receives patch releases also after the next feature release is available. Starting with 5.15 LTS, LTS releases are available only to the commercial license holders. For open source users, such LTS releases are available as regular releases only, thus 5.15 is now in the commercial-only LTS phase. Qt 5.12 LTS was the last Qt version to offer an offline ins ...

Long-term Support
Long-term support (LTS) is a product lifecycle management policy in which a stable release of computer software is maintained for a longer period of time than the standard edition. The term is typically reserved for open-source software, where it describes a software edition that is supported for months or years longer than the software's standard edition. ''Short term support'' (STS) is a term that distinguishes the support policy for the software's standard edition. STS software has a comparatively short life cycle, and may be afforded new features that are omitted from the LTS edition to avoid potentially compromising the stability or compatibility of the LTS release. Characteristics LTS applies the tenets of reliability engineering to the software development process and software release life cycle. Long-term support extends the period of software maintenance; it also alters the type and frequency of software updates ( patches) to reduce the risk, expense, and disruption of ...

Wayland (display Server Protocol)
Wayland is a communication protocol that specifies the communication between a display server and its clients, as well as a C library implementation of that protocol. A display server using the Wayland protocol is called a ''Wayland compositor'', because it additionally performs the task of a compositing window manager. Wayland is developed by a group of volunteers initially led by Kristian Høgsberg as a free and open-source community-driven project with the aim of replacing the X Window System with a modern, secure simpler windowing system in Linux and other Unix-like operating systems. The project's source code is published under the terms of the MIT License, a permissive free software licence. As part of its efforts, the Wayland project also develops a reference implementation of a Wayland compositor called ''Weston''. Overview The Wayland Display Server project was started by Red Hat developer Kristian Høgsberg in 2008. Beginning around 2010, Linux desktop graphics ...

CoAP
Constrained Application Protocol (CoAP) is a specialized Internet application protocol for constrained devices, as defined iRFC 7252 It enables those constrained devices called "nodes" to communicate with the wider Internet using similar protocols. CoAP is designed for use between devices on the same constrained network (e.g., low-power, lossy networks), between devices and general nodes on the Internet, and between devices on different constrained networks both joined by an internet. CoAP is also being used via other mechanisms, such as SMS on mobile communication networks. CoAP is an application-layer protocol that is intended for use in resource-constrained Internet devices, such as wireless sensor network nodes. CoAP is designed to easily translate to HTTP for simplified integration with the web, while also meeting specialized requirements such as multicast support, very low overhead, and simplicity. Multicast, low overhead, and simplicity are important for Internet of things ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adobe After Effects
Adobe After Effects is a digital visual effects, motion graphics, and compositing application developed by Adobe Inc., and used in the post-production process of film making, video games and television production. Among other things, After Effects can be used for keying, tracking, compositing, and animation. It also functions as a very basic non-linear editor, audio editor, and media transcoder. In 2019, the program won an Academy Award for scientific and technical achievement. History After Effects was originally created by David Herbstman, David Simons, Daniel Wilk, David M. Cotter, and Russell Belfer at the Company of Science and Art in Providence, Rhode Island, where the first two versions of the software, 1.0 (January 1993) and 1.1, were released by the company. CoSA, whose CEO was William J. O'Farrell, along with After Effects was then acquired by Aldus Corporation in July 1993, which was in turn acquired by Adobe in 1994, and with it PageMaker. Adobe's first new release ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sketch (software)
Sketch is a vector graphics editor for macOS developed by the Dutch company Sketch B.V. (formerly named Bohemian Coding). It was first released on 7 September 2010 and won an Apple Design Award in 2012. It also has a web application that allows users to share files online. It is primarily used for user interface and user experience design of websites and mobile apps and does not include print design features. Sketch has more recently added features for prototyping and collaboration. Being only available for macOS, third party software and handoff tools may be used to view Sketch designs on other platforms. Overview Sketch is used mainly for designing the UI and UX of mobile apps and web. The files designed in Sketch are saved in its own .sketch file format, though the files can also be opened in Adobe Illustrator, Adobe Photoshop, and other programs. The designs can also be exported to raster or vector formats such as PNG, JPG, SVG, and PDF. The designs created in Sketc ...

HTTP Strict Transport Security
HTTP Strict Transport Security (HSTS) is a policy mechanism that helps to protect websites against man-in-the-middle attacks such as protocol downgrade attacks and cookie hijacking. It allows web servers to declare that web browsers (or other complying user agents) should automatically interact with it using only HTTPS connections, which provide Transport Layer Security (TLS/SSL), unlike the insecure HTTP used alone. HSTS is an IETF standards track protocol and is specified in . The HSTS Policy is communicated by the server to the user agent via an HTTP response header field named "Strict-Transport-Security". HSTS Policy specifies a period of time during which the user agent should only access the server in a secure fashion. Websites using HSTS often do not accept clear text HTTP, either by rejecting connections over HTTP or systematically redirecting users to HTTPS (though this is not required by the specification). The consequence of this is that a user-agent not capable of d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WebSockets
WebSocket is a computer communications protocol, providing full-duplex communication channels over a single TCP connection. The WebSocket protocol was standardized by the IETF as in 2011. The current API specification allowing web applications to use this protocol is known as ''WebSockets''. It is a living standard maintained by the WHATWG and a successor to ''The WebSocket API'' from the W3C. WebSocket is distinct from HTTP. Both protocols are located at layer 7 in the OSI model and depend on TCP at layer 4. Although they are different, states that WebSocket "is designed to work over HTTP ports 443 and 80 as well as to support HTTP proxies and intermediaries", thus making it compatible with HTTP. To achieve compatibility, the WebSocket handshake uses the HTTP Upgrade header to change from the HTTP protocol to the WebSocket protocol. The WebSocket protocol enables interaction between a web browser (or other client application) and a web server with lower overhead t ...

ANGLE (software)
ANGLE (''Almost Native Graphics Layer Engine'') is an open source, cross-platform graphics engine abstraction layer developed by Google. ANGLE translates OpenGL ES 2/3 calls to DirectX 9, 11, OpenGL or Vulkan API calls. It's a portable version of OpenGL but with limitations of OpenGL ES standard. The API is mainly designed to bring up a high-performance OpenGL compatibility to MS Windows and to web browsers such as Chromium by translating OpenGL calls to Direct3D, which has much better driver support on Windows systems. On Windows, there are two backend renderers for ANGLE: the oldest one uses Direct3D 9.0c, while the newer one uses Direct3D 11. ANGLE is currently used by Google Chrome (it's embedded into the Blink browser engine), Firefox, Edge, WebKit, and the Qt Framework. The engine is also used by Windows 10 for compatibility with apps ported from Android. Throughout 2019 Apple team contributed a Metal API backend for the ANGLE so Apple devices could run on their nati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromium (web Browser)
Chromium is a free and open-source web browser project, mainly developed and maintained by Google. This codebase provides the vast majority of code for the Google Chrome browser, which is proprietary software and has some additional features. The Chromium codebase is widely used. Microsoft Edge, Samsung Internet, Opera, and many other browsers are based on the Chromium code. Moreover, significant portions of the code are used by several app frameworks. Google does not provide an official stable version of the Chromium browser, but does provide official API keys for some features, such as speech to text and translation. Licensing Chromium is a free and open-source software project. The Google-authored portion is shared under the 3-clause BSD license. Third party dependencies are subject to a variety of licenses, including MIT, LGPL, Ms-PL, and an MPL/GPL/ LGPL tri-license. This licensing permits any party to build the codebase and share the resulting browser executa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows Phone
Windows Phone (WP) is a discontinued family of mobile operating systems developed by Microsoft for smartphones as the replacement successor to Windows Mobile and Zune. Windows Phone featured a new user interface derived from the Metro design language. Unlike Windows Mobile, it was primarily aimed at the consumer market rather than the enterprise market. It was first launched in October 2010 with Windows Phone 7. Windows Phone 8 succeeded it in 2012, replacing the Windows CE-based kernel of Windows Phone 7 with the Windows NT kernel used by the PC versions of Windows (and, in particular, a large amount of internal components from Windows 8). Due to these changes, the OS was incompatible with all existing Windows Phone 7 devices, although it still supported apps originally developed for Windows Phone 7. In 2014, Microsoft released the Windows Phone 8.1 update, which introduced the Cortana virtual assistant, and Windows Runtime platform support to create cross-platform apps betwee ...

Windows Runtime
Windows Runtime (WinRT) is a platform-agnostic component and application architecture first introduced in Windows 8 and Windows Server 2012 in 2012. It is implemented in C++ and officially supports development in C++ (via C++/WinRT, C++/CX or WRL), Rust/WinRT, Python/WinRT, JavaScript-TypeScript, and the managed code languages C# and Visual Basic .NET (VB.NET). WinRT is not a runtime in a traditional sense but rather a language-independent application binary interface based on COM to allow APIs to be consumed from multiple languages, with services usually provided by a full-blown runtime, such as type activation. Apps using the Windows Runtime may run inside a sandboxed environment to allow greater security and stability and can natively support both x86 and ARM. WinRT components are designed with interoperability among multiple languages and APIs in mind, including native, managed and scripting languages. Built-in APIs provided by Windows which use the WinRT ABI are commonly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
