This example demonstrates a PowerShell script that configures and repeatedly resets the IPMI watchdog timer on a SuperMicro system running Windows. It shows the low-level IPMI command sequence for setting the watchdog’s timer use, actions, and timeout values, then enters an infinite loop that resets the timer every five seconds to prevent a system hang from triggering a hardware reset. The script uses the `ipmicfg-win.exe` command-line tool via the `Raw-IPMI` function, which builds and sends raw IPMI byte arrays, and relies on PowerShell’s `Set-Variable` for constants and `Start-Sleep` for the polling interval. The watchdog is set to no action on timeout, with logging disabled, and the code explicitly defines the timer’s operating mode and flag bits per the IPMI 2.0 specification.

This example demonstrates a PowerShell workaround for bypassing SSL certificate validation errors when using `Invoke-WebRequest` to access an HTTPS resource by IP address. The script defines a custom C# class, `TrustAllCertsPolicy`, which implements the `ICertificatePolicy` interface and overrides `CheckValidationResult` to always return `true`. It then assigns an instance of this policy to `[System.Net.ServicePointManager]::CertificatePolicy` before making the web request. The visualization would likely show the request succeeding where it previously failed, highlighting the difference in error handling for untrusted certificates. The code relies on .NET’s `System.Net` and `System.Security.Cryptography.X509Certificates` namespaces.

This example visualizes a system administration workflow that automatically masks or unmasksthe Linux sleep and suspend targets based on active SSH sessions. It shows a shell script that counts established SSH connections on port 22 using `ss` and `awk`, then conditionally runs `systemctl mask` or `systemctl unmask` on `sleep.target` and `suspend.target`. The visualization highlights the script’s branching logic driven by `PAM_TYPE` (open or close session) and the connection count. No external charting library is used; the code relies on standard shell utilities (`ss`, `awk`, `logger`, `sudo`) to manage systemd power management.

This visualization demonstrates an automatic root logout mechanism for interactive shell sessions. The code appends a configuration block to `/root/.bash_profile` that sets a 600-second idle timeout (`TMOUT`) for interactive shells, enforced via a `case` statement checking for the `i` flag in shell options. The script uses `sudo tee` to safely write the configuration with root privileges. The rendering approach is entirely text-based, showing the shell script and its embedded here-document that modifies bash startup behavior. No graphical libraries or data sources are involved; the visualization highlights the code structure and the logic for auto-logging out idle root sessions.

Power Query CurrentUser via a lightweight PowerShell HTTP API

This example demonstrates how Power Query can obtain the current Windows user by querying a lightweight PowerShell HTTP API. It shows the result of a `whoami` command wrapped in a JSON response. The Power Query code uses `Web.Contents` to call the local HTTP endpoint at `http://localhost:8888/?command=whoami`, and then parses the returned JSON with `Json.Document`. The underlying HTTP API service is built from a PowerShell script, based on the referenced blog post, which executes commands and returns their output. This approach provides a simple bridge between Power Query’s data-fetching capabilities and PowerShell’s system introspection.

Quick way to mute Skype on Windows

This example shows a PowerShell script that mutes Skype on Windows by sending the CTRL+M keystroke to the active Skype window, then restores focus to the previously active window. It uses the Windows API via `Add-Type` with `user32.dll` functions `GetForegroundWindow` and `SetForegroundWindow`, along with the `wscript.shell` COM object’s `AppActivate` and `SendKeys` methods. The script identifies the current foreground window, checks if Skype is active, and after sending the mute command, reactivates the original window by its process’s `MainWindowTitle`. No data source or rendering is involved; it is a utility automation script.

This visualization demonstrates the interaction between R and PowerShell, showing how a system call from an R environment triggers a PowerShell script that manipulates data. The code uses the `system2` function to execute a PowerShell command with a specified file path, passing arguments to run `coolScript.ps1`. The example highlights the practical integration of two scripting environments, where R serves as the orchestrator for external process execution. The rendering relies on the command-line interface rather than graphical libraries, focusing on the workflow of invoking and managing external scripts from within an R session. The data flow is implicit in the script's execution, emphasizing interoperability over visual output.

Power Query script to get msmdsrv.exe port number via R

This example shows how to retrieve the port number of the msmdsrv.exe process by combining R scripts with Power Query’s M language. It first runs a system command via `system2` to capture the task list and netstat output, then parses the results using `read.fwf` with fixed-width columns. The M code invokes the R script through `R.Execute`, formats the resulting tables with `Table.TransformColumns` and `Table.PromoteHeaders`, and finally joins the process ID from the task list with the matching netstat entry to extract the local address port. The visualization relies on text-based data processing rather than graphical libraries.

List Azure File Shared Storage using the REST API and Powershell

This example demonstrates how to list Azure File Shared Storage contents using the REST API and PowerShell. It constructs a signed request by building a canonicalized signature string with the account key and HMAC-SHA256 encryption, then sends a GET request through `Invoke-RestMethod`. The code explicitly sets required headers such as `x-ms-date`, `x-ms-version`, and `Authorization`, and outputs the signature for inspection. The script uses PowerShell’s `System.Security.Cryptography.HMACSHA256` and `System.Uri` classes to compute authentication and parse the endpoint.
