As I kept running into GitHub auth issues on each new local setups, I documented the steps here.

This gist documents how to set up your local dev env, especially on a headless Ubuntu machine, to push local Git changes to remote GitHub repositories.

It features

• fine-grained auth token
• headless env, e.g. remote ubuntu dev machine, where browser-based auth does not work well

Generate a personal access token in GitHub UI

To acquire the permission to push local changes to the remoate GitHub repos.

hackjutsu

git branch --set-upstream-to <remote-branch>
# example
git branch --set-upstream-to origin feature-branch

# show up which remote branch a local branch is tracking
git branch -vv

sets the default remote branch for the current local branch.

A new Deployment will take effect when it's applied.

kubectl apply -f deployment.yaml
kubectl get deployment myapp-deployment # to verify the deployment

The kubectl apply command and the kubectl rollout command serve different purposes in managing deployments in Kubernetes.

kubectl apply

• Primary Use: The kubectl apply command is used to create or update resources in a Kubernetes cluster. It takes a configuration file (usually in YAML format) and applies it to the cluster. This is the command you use to initially create objects like Deployments, Services, ConfigMaps, etc., or to apply changes to them.

sudo vi /etc/udev/rules.d/92-usb-input-no-powersave.rules
# with content: ACTION=="add", SUBSYSTEM=="input", TEST=="power/control", ATTR{power/control}="on"
# reboot

# how this works
# When you connect an input device, such as a keyboard or mouse, to your system, udev triggers various rules. 
# If the connected device is recognized as part of the input subsystem and has a power/control attribute, this 
# rule will set that attribute to "on", effectively disabling USB autosuspend for that device.

import HighlightJS from 'highlight.js'

createHighlightedCodeBlock (content, language) {
  let lineNumber = 0
  const highlightedContent = HighlightJS.highlightAuto(content, [language]).value

  /* Highlight.js wraps comment blocks inside <span class="hljs-comment"></span>.
     However, when the multi-line comment block is broken down into diffirent
     table rows, only the first row, which is appended by the <span> tag, is
     highlighted. The following code fixes it by appending <span> to each line
