Which vMotion configuration minimizes VM stun duration for latency-sensitive apps?

When migrating a powered-on virtual machine between ESXi hosts in a vSphere environment, the final memory synchronization phase involves a brief period where the VM is paused, known as the stun period. For small applications with strict latency requirements, this pause can potentially trigger application-level timeouts or disconnects. The duration of this st

Vault Namespace Token Policy Inheritance: Unclear Automatic Propagation Constraint

Vault Namespace Token Policy Inheritance The goal is to clarify whether a token created in a parent namespace with an attached policy automatically grants the same policy permissions when the token is used to access secrets in a child namespace. Current documentation does not state if the policy is inherited, overridden, or requires explicit binding in each

preload() asset readiness consistency across p5.js deployment targets

This question addresses whether p5.js preload() uniformly ensures that referenced assets are fully available before setup() begins execution, regardless of the deployment target. The documented feature specifies that preload() runs asynchronously and must complete before the sketch lifecycle proceeds to setup(), but practical guarantees vary across environme

string(TIMESTAMP) yields undefined %Z output on systems lacking timezone database

Goal Determine whether CMake's string(TIMESTAMP) can reliably produce a timezone name ( %Z ) when the underlying system lacks timezone data, and what the expected output should be in such cases. Constraints/Uncertainty The command forwards the format string to the C runtime's strftime , which may return an empty string for %Z if timezone information is unava

DeprecationWarnings: Transitioning from default silence in Python 3.7+

Warning Visibility and Noise Management Starting with Python 3.7, DeprecationWarnings are ignored by default. This change was implemented to reduce notification noise for end-users, but it creates a visibility gap for developers who need to identify outdated API usage before a feature is fully removed in later versions.

RecursionError in Python submissions on LeetCode judge

Recursive Python solutions are common on LeetCode, and local development environments often allow increasing the recursion limit. The judge environment is documented to use a default recursion limit and to restrict attempts to raise it. The precise interaction between sys.setrecursionlimit and the judge's runtime is not clearly specified in the public langua

Backtick key needs to be pressed twice to type a backtick character on Windows 11 with NZ Aotearoa Keyboard

There appear to be hundreds of these questions already and I do feel bad for writing another, but I have not found any solution for Windows 11. It seems all the solutions for older versions of Windows do not apply to Windows 11. My hope is a fresh new answer will serve the community well. Is that possible? This is a new computer with Windows 11 - no upgrade
