Code to purge data based on creation date

Only one thing can spark more joy than cleaning up old data. Doggos. Yesterday, I talked about batching deletes, and the day before I talked about how much I like to delete data, and why it's necessary to do it, despite being a data packrat.

I lament that I do not have a copy of every paper I typed in high school or college–and I envy those who do. You never know when you’ll need notes from that meeting 6 years ago, or when you’ll need that funny GIF you created for an inside joke you no longer remember.

Building a Twitter-bot RSS Aggregator

I hate RSS readers

I love my new bot

For some reason, about once a year, I go hunting for a new RSS reader so I can keep track of blogs that I like to read. It’s always the same process:
