A sample UML class and sequence diagram for the Command design pattern. [3]In the above UML class diagram, the Invoker class doesn't implement a request directly. Instead, Invoker refers to the Command interface to perform a request (command.execute()), which makes the Invoker independent of how the request is performed.
GitHub (/ ˈ ɡ ɪ t h ʌ b /) is a proprietary developer platform that allows developers to create, store, manage, and share their code. It uses Git to provide distributed version control and GitHub itself provides access control, bug tracking, software feature requests, task management, continuous integration, and wikis for every project.

The project consisted of 4 modules: an economic simulator, custom software to check factory performance, an operations room, and a national network of telex machines that were linked to one mainframe computer. [2] Project Cybersyn was based on viable system model theory approach to organizational design and featured innovative technology for ...
Simple Machines Forum (SMF) software is an open-source web application that provides Internet forum and message board services. It is developed by Simple Machines. It is developed by Simple Machines. The name reflects the creator's initial goal of providing a website that could be operated by novice programmers and requires minimal server ...
Working copies effectively function as remote backups, which avoids relying on one physical machine as a single point of failure. [5] Allows various development models to be used, such as using development branches or a Commander/Lieutenant model. [6] Permits centralized control of the "release version" of the project [citation needed]
Arithmetic-based Turing-complete machines use an arithmetic operation and a conditional jump. Like the two previous universal computers, this class is also Turing-complete. The instruction operates on integers which may also be addresses in memory. Currently there are several known OISCs of this class, based on different arithmetic operations:
A 1-bit saturating counter (essentially a flip-flop) records the last outcome of the branch. This is the most simple version of dynamic branch predictor possible, although it is not very accurate. A 2-bit saturating counter [1] is a state machine with four states: Figure 2: State diagram of 2-bit saturating counter. Strongly not taken; Weakly ...
If the branch is not taken, the pipeline stays full. If the branch is taken, the instruction is flushed (marked as if it were a NOP), and one cycle's opportunity to finish an instruction is lost. Branch Likely: Always fetch the instruction after the branch from the instruction cache, but only execute it if the branch was taken.
