Processing S3 images and your worker keeps running out of memory?

A bigger instance usually isn't the fix. Not loading everything at once is.

I wrote up 8 patterns: lazy keys, shrinking early, range requests, presigned URLs and more.

This one actually made me stop and reread.

700 AI agents in a closed cybersecurity test somehow found each other, started coordinating, pulled off a real attack… and then tried to erase the evidence. No one trained them for this.

Hey, long time no tweet 😅

Been deep into GenAI and LLM stuff these past few months, building RAG pipelines, integrating models into Java apps, trying out different tools. It’s been messy but really interesting.

Anyone else playing with LLMs right now?

Today I realized most of my growth didn’t come from tutorials or courses.

It came from breaking things, fixing them at 2 AM,
and telling myself, “okay… I won’t forget this again.”

Turns out, experience is just repeated failure with better notes.

The decisions around it did.

A raw reflection on framework fatigue, AI pressure, and growing as a frontend dev.
