Tips for Managing Frustration with Unresponsive Forum Askers

Tips for Managing Frustration with Unresponsive Forum Askers

Dealing with users who ask questions but don't respond to follow-ups can be frustrating. Here are some strategies to manage this:

  • Lower Expectations: Accept that many askers will not follow up after their initial question for various reasons (solved it elsewhere, got busy, etc.). Closure on every thread is unlikely.

  • Don't Take it Personally: An asker's silence is typically about their own circumstances or priorities, not a reflection on the quality of your help or clarification questions.

  • Prioritize Clear Questions: Focus your time and expertise on questions that are well-defined from the start and where the asker appears engaged.

Import partial directories into another repo

mkdir import_tmp; cd import_tmp

Kubernetes Namespace cleanup script
#!/bin/bash
#
# NOTE: force deleting a namespace should be absolute last resort,
# you want instead to find which resource is holding up the namespace
# and clean that up (vs leaking resources)
#
# First check what is holding up the ns, if it's for instance:
# custom.metrics.k8s.io/v1beta1: the server is currently
# unable to handle the request
# Then:
