PowerShell 7.5, is the latest stable release & was released in January 2025, is built on .NET 9.0.1 and includes enhancements in performance, usability, and security. Key updates include improvements to tab completion, such as better type inference and new argument completers, as well as fixes for Invoke-WebRequest and Invoke-RestMethod.
For many of the above uses, Active Scripting is an addition to Windows that is similar to the functionality of Unix shell scripts, as well as an incremental improvement upon batch files (command.com), Windows NT style shell scripts (cmd.exe) and, by way of VBScript, the replacement for QBasic, which was last available on the supplementary disc ...
In computer operating systems, a process (or task) may wait for another process to complete its execution. In most systems, a parent process can create an independently executing child process . The parent process may then issue a wait system call , which suspends the execution of the parent process while the child executes.
wait normally returns the exit status of the last job which terminated. It may also return 127 in the event that n specifies a non-existent job or zero if there were no jobs to wait for. Because wait needs to be aware of the job table of the current shell execution environment, it is usually implemented as a shell builtin .
In computer science and software engineering, busy-waiting, busy-looping or spinning is a technique in which a process repeatedly checks to see if a condition is true, such as whether keyboard input or a lock is available. Spinning can also be used to generate an arbitrary time delay, a technique that was necessary on systems that lacked a ...
It was never approved as an RFC, but it has since been cited and used by other RFCs (e.g. RFC 2693) and several other publications. [7] It was originally intended for use in SPKI. Rivest's format defines an S-expression as being either an octet-string (a series of bytes) or a finite list of other S-expressions. It describes three interchange ...
Each output can be the input to an arbitrary number of neurons, including itself (i.e., self-loops are possible). However, an output cannot connect more than once with a single neuron. Self-loops do not cause contradictions, since the network operates in synchronous discrete time-steps.
If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.
