openGym v. 1.3

A while ago I posted openGym here a self-hosted gym and body-weight tracker built with React + Node. It runs in two Docker containers, supports passkeys, has an Android APK, 14 languages and is AGPL licensed. The most common request I got since then was basically: "can you add some kind of coaching?

Is there reputable FOSS library that validates temp email?

I know it is a whack-a-mole situtation but I want to know if there is a library that already cover major/famous temporary emails. I plan to restrict registration from temp mail providers to reduce cleanup work from pockers. Again not a service as I will not send emails to third-party. Also I don't n

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
