#6 Uptime Sync: Kubernetes 1.35, PostgreSQL at 800M Users & TCP Debugging

Welcome to this week's Uptime Sync. This issue opens with Kubernetes 1.35's game-changing Day 2 operations features that actually matter in production, OpenAI's deep dive into scaling PostgreSQL to handle 800 million ChatGPT users without breaking, a new grad's honest reflections on what working alongside senior engineers actually teaches you, a DevOps security war story about why exposed Nginx server banners matter more than you think, practical strategies for scaling APIs when your traffic suddenly 10x's, and a clear explanation of Multi-Paxos consensus in distributed databases.

On the tutorial front, you'll debug TCP retransmissions in Linux using ss and tcpdump like a sysadmin detective, safely roll back Terraform infrastructure changes without panic, harden Kubernetes security by baking DevSecOps practices into your workflow, learn Docker fundamentals by actually using Docker itself, build your dream terminal setup with AI agents, Oh-My-Zsh, Neovim and Starship, and troubleshoot SQL Server performance issues with proven fixes that work.

To wrap things up, this week's projects bring you OpenClaw for deploying your own cross-platform AI assistant, ConvertX as a self-hosted file converter supporting 1000+ formats, Quack-Cluster for running serverless distributed SQL queries with DuckDB and Ray, Roots for managing game server Docker containers as a daemon, and Umami: a privacy-focused, open-source analytics platform that replaces Google Analytics without the tracking.
