Logical Domains (LDoms or LDOM) is the server virtualization and partitioning technology for SPARC V9 processors. It was first released by Sun Microsystems in April 2007. After the Oracle acquisition of Sun in January 2010, the product has been re-branded as Oracle VM Server for SPARC from version 2.0 onwards.
In 2021, Lean 4 was released, which was a reimplementation of the Lean theorem prover capable of producing C code which is then compiled, enabling the development of efficient domain-specific automation. [4] Lean 4 also contains a macro system and improved type class synthesis and memory management procedures over the previous version. Another ...
SKI combinator calculus can also implement Boolean logic in the form of an if-then-else structure. An if-then-else structure consists of a Boolean expression that is either true (T) or false (F) and two arguments, such that: Txy = x. and Fxy = y. The key is in defining the two Boolean expressions. The first works just like one of our basic ...
Prolog is a logic programming language that has its origins in artificial intelligence, automated theorem proving and computational linguistics. [1] [2] [3]Prolog has its roots in first-order logic, a formal logic, and unlike many other programming languages, Prolog is intended primarily as a declarative programming language: the program is a set of facts and rules, which define relations.
In October 2012, a group of telecom operators published a white paper [4] at a conference in Darmstadt, Germany, on software-defined networking (SDN) and OpenFlow.The Call for Action concluding the White Paper led to the creation of the Network Functions Virtualization (NFV) Industry Specification Group (ISG) [5] within the European Telecommunications Standards Institute (ETSI).
The topmost value is evaluated as a Boolean and, if true, the second topmost value is pushed back on the stack. IFTE allows a third "else" value that will be pushed back on the stack if the Boolean is false. The following example uses the IFT function to pop an object from the bottom of the stack and, if it is equal to 1, replaces it with "One":
This list of JVM Languages comprises notable computer programming languages that are used to produce computer software that runs on the Java virtual machine (JVM). Some of these languages are interpreted by a Java program, and some are compiled to Java bytecode and just-in-time (JIT) compiled during execution as regular Java programs to improve performance.
IBM developed the concept of hypervisors (virtual machines in CP-40 and CP-67) and in 1972 provided it for the S/370 as Virtual Machine Facility/370. [2] IBM introduced the Start Interpretive Execution (SIE) instruction (designed specifically for the execution of virtual machines) in 1983 as part of 370-XA architecture on the IBM 3081, as well as VM/XA versions of VM to exploit it.
