I am not sure if this is going to be useful to anyone, but if you’re working with AWS Linux and Windows instances (especially if these are ephemeral) you’ll know that it’s a bit of a pain to quickly connect to these.

Amazon only allows increasing the size of their AWS EBS volumes. While unfortunate, we can sympathize with Amazon, they’re doing it for a good reason (let’s leave it at that).
So, if you have let’s say 100GB EBS volume attached to your EC2 and you’re only using 20 GBs, modifying the volume to anything lower than 100 GB will generate an error: The size of a volume can only be increased, not decreased.
This essentially means you’re stuck with a large volume, wasting resources and paying large bills. The following article is a walkthrough of the process of getting around this issue and reducing the size of Amazon EBS root volume.

Recently, I came across a resource that allowed me to download the entire collection of UTZOO NetNews Archive of the earliest USENET posts.

There were approximately 2.1 million posts in these archives created between Feb 1981 and June of 1991. This article describes the journey of converting those tapes into fully searchable PostgreSQL database and later also into the usenetarchives.com website.
