Columbia Cycada
Cycada (formerly known as Cider) is a compatibility layer that aims to allow applications designed for iOS to run unmodified on the Android operating system. The method uses compile-time adaptation to run unmodified code with minimal implementation effort. The project was revealed in a conference paper by computer science researchers at Columbia University. The project enables iOS applications to adapt to Android's kernel and programming libraries. A video released shows that many applications work, including the iOS version of Yelp, Apple's iBooks software and 3D benchmarks using OpenGL. Consequent to the release of the white paper, hardware GPS support was added to the software. Unlike many other compatibility layers (such as WINE or Darling), Cycada works at the kernel level, as opposed to at user space. Cycada is not a simple APK file, and modifies the entire Linux kernel. It is unknown whether the project will be released. The original name “Cider” was most likel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jason Nieh
Jason Nieh is a professor of Computer Science and co-director of the Software Systems Laboratory at Columbia University. He is most well known for his work on virtualization. He was one of the early pioneers of operating-system-level virtualization, introducing key concepts such as process namespaces and file system layers which led to the development of Linux containers and Docker. He was an early proponent of desktop virtualization, conducting many of the early studies demonstrating the feasibility of Virtual Desktop Infrastructure. He developed and influenced many key technologies for Arm virtualization, including the Linux ARM hypervisor, KVM ARM, and Arm architecture features to support virtualization host extensions, nested virtualization, and confidential computing. He was also the first to introduce virtual machines and virtual appliances to teach hands-on computer science courses such as operating systems, which has now become common practice at many universities. ...

Wine
Wine is an alcoholic drink typically made from fermented grapes. Yeast consumes the sugar in the grapes and converts it to ethanol and carbon dioxide, releasing heat in the process. Different varieties of grapes and strains of yeasts are major factors in different styles of wine. These differences result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the grape's growing environment (terroir), and the wine production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin and permitted varieties of grapes, as well as other aspects of wine production. Wines not made from grapes involve fermentation of other crops including rice wine and other fruit wines such as plum, cherry, pomegranate, currant and elderberry. Wine has been produced for thousands of years. The earliest evidence of wine is from the Caucasus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Computing Platforms
A computing platform or digital platform is an environment in which a piece of software is executed. It may be the hardware or the operating system (OS), even a web browser and associated application programming interfaces, or other underlying software, as long as the program code is executed with it. Computing platforms have different abstraction levels, including a computer architecture, an OS, or runtime libraries. A computing platform is the stage on which computer programs can run. A platform can be seen both as a constraint on the software development process, in that different platforms provide different functionality and restrictions; and as an assistant to the development process, in that they provide low-level functionality ready-made. For example, an OS may be a platform that abstracts the underlying differences in hardware and provides a generic command for saving files or accessing the network. Components Platforms may also include: * Hardware alone, in the cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

WinObjC
Universal Windows Platform (UWP) is a computing platform created by Microsoft and first introduced in Windows 10. The purpose of this platform is to help develop universal apps that run on Windows 10, Windows 10 Mobile (discontinued), Windows 11, Xbox One, Xbox Series X/S, and HoloLens without the need to be rewritten for each. It supports Windows app development using C++, C#, VB.NET, and XAML. The API is implemented in C++, and supported in C++, VB.NET, C#, F# and JavaScript. Designed as an extension to the Windows Runtime (WinRT) platform first introduced in Windows Server 2012 and Windows 8, UWP allows developers to create apps that will potentially run on multiple types of devices. UWP does not target non-Microsoft systems. Microsoft's solution for other platforms is .NET MAUI (previously "Xamarin.Forms"), an open-source API created by Xamarin, a Microsoft subsidiary since 2016. Community solutions also exist for non-targeted platforms, such as the Uno Platform. Compat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apples
An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple fruit tree, trees are agriculture, cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, ''Malus sieversii'', is still found today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonization of the Americas, European colonists. Apples have Religion, religious and mythology, mythological significance in many cultures, including Norse mythology, Norse, Greek mythology, Greek, and Christianity in Europe, European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. Generally, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after plantin ...

Darwin Kernel
XNU is the computer operating system (OS) kernel developed at Apple Inc. since December 1996 for use in the Mac OS X (now macOS) operating system and released as free and open-source software as part of the Darwin OS, which in addition to macOS is also the basis for the Apple TV Software, iOS, iPadOS, watchOS, and tvOS OSes. ''XNU'' is an abbreviation of ''X is Not Unix''. Originally developed by NeXT for the NeXTSTEP operating system, XNU was a hybrid kernel derived from version 2.5 of the Mach kernel developed at Carnegie Mellon University, which incorporated the bulk of the 4.3BSD kernel modified to run atop Mach primitives, along with an application programming interface (API) in Objective-C for writing drivers named Driver Kit. After Apple acquired NeXT, the kernel was updated with code derived from OSFMK 7.3 from OSF, and the FreeBSD project, and the Driver Kit was replaced with a C++ API for writing drivers named I/O Kit.

Android OS
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with additional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
