Miranda (programming Language)
Miranda is a lazy evaluation, lazy, functional programming, purely functional programming language designed by David Turner (computer scientist), David Turner as a successor to his earlier programming languages SASL programming language, SASL and Kent Recursive Calculator, KRC, using some concepts from ML (programming language), ML and Hope (programming language), Hope. It was produced by Research Software Ltd. of England (which holds a trademark on the name ''Miranda'') and was the first purely functional language to be commercially supported. Miranda was first released in 1985 as a fast interpreter in C (programming language), C for Unix-flavour operating systems, with subsequent releases in 1987 and 1989. It had a strong influence on the later Haskell language. Turner stated that the benefits of Miranda over Haskell are: "Smaller language, simpler type system, simpler arithmetic". In 2020 a version of Miranda was released as open source under a BSD 2-Clause, BSD licence. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lazy Evaluation
In programming language theory, lazy evaluation, or call-by-need, is an evaluation strategy which delays the evaluation of an Expression (computer science), expression until its value is needed (non-strict evaluation) and which avoids repeated evaluations (by the use of Sharing (computer science), sharing). The benefits of lazy evaluation include: * The ability to define control flow (structures) as abstractions instead of Language primitive, primitives. * The ability to define actual infinity, potentially infinite data structures. This allows for more straightforward implementation of some algorithms. * The ability to define partly-defined data structures where some elements are errors. This allows for rapid prototyping. Lazy evaluation is often combined with memoization, as described in Jon Bentley (computer scientist), Jon Bentley's ''Writing Efficient Programs''. After a function's value is computed for that Parameter (computer programming), parameter or set of parameters, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SASL Programming Language
SASL (St Andrews Static Language, alternatively St Andrews Standard Language) is a purely functional programming language developed by David Turner at the University of St Andrews in 1972, based on the applicative subset of ISWIM. In 1976 Turner redesigned and reimplemented it as a non-strict (lazy) language. In this form it was the foundation of Turner's later languages Kent Recursive Calculator (KRC) and Miranda, but SASL appears to be untyped whereas Miranda has polymorphic types.

John William Waterhouse
John William Waterhouse (baptised 6 April 184910 February 1917) was an English painter known for working first in the Academic style and for then embracing the Pre-Raphaelite Brotherhood's style and subject matter. His paintings are known for their depictions of women from both ancient Greek mythology and Arthurian legend. A high proportion depict a single young and beautiful woman in a historical costume and setting, though there are some ventures into Orientalist painting and genre painting, still mostly featuring women. Born in Rome to English parents who were both painters, Waterhouse later moved to London, where he enrolled in the Royal Academy of Art Schools. He soon began exhibiting at their annual summer exhibitions, focusing on the creation of large canvas works depicting scenes from the daily life and mythology of ancient Greece. Many of his paintings are based on authors such as Homer, Ovid, Shakespeare, Tennyson, or Keats. Waterhouse's work is displayed in m ...

Windows Subsystem For Linux
Windows Subsystem for Linux (WSL) is a component of Microsoft Windows that allows the use of a GNU/Linux environment from within Windows, foregoing the overhead of a virtual machine and being an alternative to dual booting. The WSL command-line interface tool is installed by default in Windows 11, but a distribution must be downloaded and installed through it before use. In Windows 10, WSL can be installed either by joining the Windows Insider program or manually via Microsoft Store or Winget. The original version, WSL 1, differs significantly from the second major version, WSL 2. WSL 1 (released August 2, 2016), acted as a compatibility layer for running Linux binary executables (in ELF format) by implementing Linux system calls in the Windows kernel. WSL 2 (announced May 2019), introduced a real Linux kernel a managed virtual machine (via Hyper-V) that implements the full Linux kernel. As a result, WSL 2 is compatible with more Linux binaries as not all system calls wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Debian
Debian () is a free and open-source software, free and open source Linux distribution, developed by the Debian Project, which was established by Ian Murdock in August 1993. Debian is one of the oldest operating systems based on the Linux kernel, and is the basis of List of Linux distributions#Debian-based, many other Linux distributions. As of September 2023, Debian is the second-oldest Linux distribution still in active development: only Slackware is older. The project is coordinated over the Internet by a team of volunteers guided by the List of Debian project leaders, Debian Project Leader and three foundational documents: the Debian Social Contract, the Debian Constitution, and the Debian Free Software Guidelines. In general, Debian has been developed openly and distributed freely according to some of the principles of the GNU Project and Free Software. Because of this, the Free Software Foundation sponsored the project from November 1994 to November 1995. However, Debian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C18 (C Standard Revision)
C17, formally ISO/IEC 9899:2018, is an open standard for the C programming language, prepared in 2017 and published on 2018-07-05. It replaced C11 (standard ISO/IEC 9899:2011), and is superseded by C23 (ISO/IEC 9899:2024) since October 2024. Since it was under development in 2017, and officially published in 2018, C17 is sometimes referred to as C18. Changes from C11 C17 fixes numerous minor defects in C11 without introducing new language features. The __STDC_VERSION__ macro is increased to the value 201710L. For a detailed list of changes from the previous standard, see ''Clarification Request Summary for C11''. Compiler support List of compilers supporting C17: * GCC 8.1.0 * LLVM Clang 7.0.0 * IAR EWARM v8.40.1 * Microsoft Visual C++ VS 2019 (16.8) * Pelles C 9.00 See also * C++23, C++20, C++17, C++14, C++11, C++03, C++98, versions of the C++ programming language standard * Compatibility of C and C++ References Further reading N2176(final draft of C17 ...

C11 (C Standard Revision)
C11 (previously C1X, formally ISO/IEC 9899:2011) is a past standard for the C programming language. It replaced C99 (standard ISO/IEC 9899:1999) and has been superseded by C17 (standard ISO/IEC 9899:2018). C11 mainly standardizes features already supported by common contemporary compilers, and includes a detailed memory model to better support multiple threads of execution. Due to delayed availability of conforming C99 implementations, C11 makes certain features optional, to make it easier to comply with the core language standard. The final draft, N1570, was published in April 2011. The new standard passed its final draft review on October 10, 2011 and was officially ratified by ISO and published as ISO/IEC 9899:2011 on December 8, 2011, with no comments requiring resolution by participating national bodies. A standard macro __STDC_VERSION__ is defined with value 201112L to indicate that C11 support is available. Changes from C99 The standard includes several changes to ...
