Is Anyone Actually Reading Your Abuse Reports?

Somewhere on a hosting provider's /24, a scanner is working through port 22. It fails on one address, moves to the next in the block, fails again, and keeps walking. Every server it touches that has fail2ban configured with an automated reporting action fires off an abuse report. By evening, the ope

How Do Big Frontend Applications Scale?

A small frontend application is easy to understand. A few components. A few API calls. A handful of pages. You can usually open the project, look around for a few minutes, and understand how most things work. But applications rarely stay small. As the product grows, you may eventually have: Hu

Persist AI Agent State on Free Servers with JSON Checkpoints

I stop losing AI agent insights on free ephemeral servers by writing a JSON checkpoint after every meaningful step and loading that file before the next session does any real work. Token grants fund compute, but only an external persistence layer preserves the context the agent already paid to earn.

Migrating Petabyte-Scale Parquet to Iceberg Without Dropping a Single Row

Roughly 70% of companies that migrate their data lakes to Iceberg end up with "zombie" datasets: half-migrated, out-of-sync, and consuming double the storage costs. They treat the migration like a switch-flip, and that is exactly how you cause a P0 incident. Why I chose this topic: I’ve been burne

Don't put an LLM in charge of your production database

Last June, a junior analyst pushed a "helpful" GenAI assistant to our internal Tableau-connected lakehouse. Within forty minutes, the agent generated a SELECT * across a 40-terabyte partitioned table joined against a cross-region S3 bucket. The query didn't just fail; it locked the Databricks SQL Wa

Putting GitHub Actions runners on your private network with NetBird

Sooner or later a CI job needs to reach something that is not on the public internet. A staging database, an internal container registry, a deploy target sitting behind a firewall, an integration test suite that talks to a service you have no intention of exposing. The usual answers are not great.

A Webhook, a Free Server, and a Token Ledger

A developer needed a small notification service. GitHub pushes had to become short messages in a private chat. The budget was zero, and the tolerance for maintenance was lower than the budget. The obvious options were a hosted function or a cheap VPS. Both cost something, and both came with account

Why AI food looks like that

There is a torrent of unappetizing slop coming from restaurants, cafes, and brands that are increasingly turning to AI to generate images promoting their food. The resulting horror show includes donut shrimp, Reubens from the deep, wormlike noodles, and noodle-like pastries and stringy chicken. Ther
