PDF tools for comparing PDFs visually (overlaying two PDFs to see changed areas) and using a perceptual hash (numerical value indicating visual difference between the two files).
Useful for command line review of PDFs and de-duplication. Configure git to use these tools for better PDF history / comparison in git.
These scripts require imagemagick and poppler. Both installed from homebrew.
Setup git to use a custom diff using:
This guide is for homelab admins who understand IPv4s well but find setting up IPv6 hard or annoying because things work differently. In some ways, managing an IPv6 network can be simpler than IPv4, one just needs to learn some new concepts and discard some old ones.
Let’s begin.
First of all, there are some concepts that one must unlearn from ipv4:
Concept 1
It is, unfortunately, extremely common for customers and enterprises operating in AWS to have chosen a workload/storage bearing account (more than likely, the main production account) as the Organization Management Account (formerly known Organization "Master" account, before AWS adopted better naming).
Many customers and companies operating in AWS made this decision in 2018 or so and its unforunately not something that can be easily changed as of 2024. Many customers have requests to AWS to make a friendly path for rehoming the Org Management account, but last I heard it is still not prioritized. Thus, we as customers are left to go through the nerve-wracking, if not dangerous process of migrating to a new AWS Organization in order to align with modern best practices and reduce common privilege escalation and account to account lateral movement concerns (made worse if you happen to have enabled things like Cloudformation Stacksets, Control Tower, or other powerful services in the same

random.SystemRandom uses os.urandom as a source of bytes, but doesn't provide a way to use a different source of bytes.
So stream_random.py is exactly that.
Then kms_random.py has raw and buffered bytestreams pulling from KMS.GenerateRandom.
The main interface is kms_random.get_kms_random(boto3_session, buffer_size=None). The default buffer size is 16, chosen arbitrarily.
I do not vouch for the randomness properties of the results.
