This Microservice Should Have Been a Library

About 6 years ago when I was a PHP ecommerce dev, I've always wanted to work with distributed systems and microservices. They seemed so cool and the new way of architecting software systems because all of big tech did it. But now working with them day to day for about 3 years I came to realize that my initial anticipation was stupid. Well, not stupid in the traditional sense, because how could I have known what I'd get myself into.

Microservices and distributed systems have been preached to solve two major problems: Scale and scale.

So let's talk about them.

What

This is open-source code that lets you generate short unique identifiers from numbers (within Postgres DB). These IDs are URL-safe, can encode several numbers, and do not contain common profanity words.

This is what they look like:

So you want to modify the text of a PDF by hand...

If you, like me, resent every dollar spent on commercial PDF tools, you might want to know how to change the text content of a PDF without having to pay for Adobe Acrobat or another PDF tool. I didn't see an obvious open-source tool that lets you dig into PDF internals, but I did discover a few useful facts about how PDFs are structured that I think may prove useful to others (or myself) in the future. They are recorded here. They are surely not universally applicable --
the PDF standard is truly Byzantine -- but they worked for my case.
