Show HN: PgDog – Scale Postgres without changing the app Hey HN! Lev and Justin here, authors of PgDog ( https://pgdog.dev/ ), a connection pooler, load balancer and database sharder for PostgreSQL. If you build apps with a lot of traffic, you know the first thing to break is the database. We are solving this with a network proxy that works without requiring application code changes or database migrations. Our post from last year: https://ift.tt/3KV5qCE The most important update: we are in production. Sharding is used a lot, with direct-to-shard queries (one shard per query) working pretty much all the time. Cross-shard (or multi-database) queries are still a work in progress, but we are making headway. Aggregate functions like count(), min(), max(), avg(), stddev() and variance() are working, without refactoring the app. PgDog calculates the aggregate in-transit, while transparently rewriting queries to fetch any missing info. For example, multi-database average calculation requires a...

Show HN: ZkzkAgent now has safe, local package management I built zkzkAgent as a fully offline, privacy-first AI assistant for Linux (LangGraph + Ollama, no cloud). It already does natural language file/process/service management, Wi-Fi healing, voice I/O, and human-in-the-loop safety for risky actions. Just added package management with these goals: - 100% local/offline capable (no web search required for known packages) - Human confirmation for every install/remove/upgrade - Smart fallback order to avoid conflicts: 1. Special cases (Postman → snap, VSCode → snap --classic, Discord → snap/flatpak, etc.) 2. Flatpak preferred for GUI apps 3. Snap when flatpak unavailable 4. apt only for CLI/system tools - Checks if already installed before proposing anything - Dry-run style preview + full command output shown - No blind execution — always asks "yes/no" for modifications Example flow for "install postman": → Detects OS & internet (once) → Recognizes snap path → pr...
