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.

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.

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

Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real
