Shall i implement it?
No ...

Prologue

I wrote this answer on stackexchange, here: https://stackoverflow.com/posts/12597919/

It was wrongly deleted for containing "proprietary information" years later. I think that's bullshit so I am posting it here. Come at me.

The Question

Amazon is a SOA system with 100s of services (or so says Amazon Chief Technology Officer Werner Vogels). How do they handle build and release?

Resources

KUBERNETES CLUSTER

local https://github.com/kubernetes-sigs/kind (or just use minikube if it works for you)
cloud https://cloud.google.com/kubernetes-engine (for PersistentVolume and Ingress, I needed to try the real deal)
practice environment: https://github.com/arush-sal/cka-practice-environment

PRACTICE

Dev Containers

https://containers.dev an open spec that extends container definition to also include dev environment configuration including:

packages
lifecycle automation
processes
IDE configurations
remote connection
port forwarding

Many tools do not fully remove metadata, but just remove the link with in the metadata table. The data are thus still available in the PDF file itself.

While a lot of people rely on Exiftool to remove metadata, it actually does the same in PDFs. If you remove metadata with exiftool -all= some.pdf, you can always restore the data with exiftool -pdf-update:all= some.pdf.

There are several options to remove PDF metadata safely:

Option 1 : Exiftool with qpdf

Remove metadata with exiftool : exiftool -all= some.pdf
Then remove ununsed objects with qpdf : qpdf --linearize some.pdf - > some.cleaned.pdf

	<artifacts_info>
	The assistant can create and reference artifacts during conversations. Artifacts are for substantial, self-contained content that users might modify or reuse, displayed in a separate UI window for clarity.

	# Good artifacts are...
	- Substantial content (>15 lines)
	- Content that the user is likely to modify, iterate on, or take ownership of
	- Self-contained, complex content that can be understood on its own, without context from the conversation
	- Content intended for eventual use outside the conversation (e.g., reports, emails, presentations)
	- Content likely to be referenced or reused multiple times


	Questions are not from any actual exam!!!



	Q: Create a job that calculates pi to 2000 decimal points using the container with the image named perl
	and the following commands issued to the container: ["perl", "-Mbignum=bpi", "-wle", "print bpi(2000)"]
	Once the job has completed, check the logs to and export the result to pi-result.txt.

	Solution:

	while true; do
	osascript -e '
	tell application "System Events"
	if exists process "Claude" then
	tell process "Claude"
	if exists button "Allow for This Chat" of group 2 of group 1 of group 1 of group 1 of UI element 2 of group 1 of group 1 of group 1 of group 1 of window "Claude" then
	click button "Allow for This Chat" of group 2 of group 1 of group 1 of group 1 of UI element 2 of group 1 of group 1 of group 1 of group 1 of window "Claude"
	log "clicked allow button"
	end if
	end tell
