A developer warns that read-only Postgres access can still harm production databases. Exploratory joins, wide aggregates, and concurrent retries consume the same resources as application traffic, so A…
A developer outlines a practical workflow combining Vercel's speed for rapid prototyping with AWS's depth for production-grade infrastructure, avoiding replatforming. The approach treats Vercel as a '…
A developer outlines a production-ready session architecture for the Model Context Protocol (MCP) that avoids sticky sessions and in-memory state. The design uses a gateway layer and external stores l…
A developer built Distill.ai, an AI agent that turns messy RFQ emails into priced quotes, and deployed it on Alibaba Cloud. The system uses a seven-stage pipeline with models from Alibaba Cloud Model …
Data Security Posture Management (DSPM) helps teams understand where sensitive data is, who can access it, and how it's protected, but traditional DSPM only scans storage systems and misses the code p…
DeepSQL, a self-hostable AI DBA agent for Postgres and MySQL, monitors workloads, optimizes slow queries, and ships BI dashboards to cut database costs by 38%. The tool installs in one line and self-h…
A developer built an offline-first sync engine in Rust, using event sourcing to reconcile data between mobile devices and a backend. The engine, shared across iOS and Android via UniFFI, stores events…
A full-stack engineer has built VulneraMCP, an AI-augmented security testing platform that uses the open-source ZAP scanning engine with a machine learning layer for bug bounty hunting. The system int…
Warden is a permission-aware retrieval and agent-authorization gateway for AI systems that enforces relationship-based, deny-aware, cross-tenant document permissions inside the retrieval path of agent…
A developer built four deterministic developer tools for the agent-coding era, all using static analysis and graph algorithms instead of LLM calls. The tools include skillcheck for SKILL.md files, mcp…
A developer describes how to architect a lean LLM caching system that survives periodic data wipes by moving cache into a small, orthogonal lookup table keyed on a stable identifier. The approach redu…
A developer fine-tuned the all-MiniLM-L6-v2 embedder on a 14-document personal corpus and measured zero improvement in retrieval metrics (Δ+0.00 MRR, Δ+0.00 nDCG@10), concluding that off-the-shelf emb…
A developer building the RE-call memory system for AI agents introduces honesty guards to prevent retrieval from returning confident noise. The system wraps retrieval with signals like gap_warning (th…
Nylas demonstrates how to build an event waitlist using an email agent that processes replies in arrival order and atomically allocates seats. The system relies on an Agent Account with a grant_id, me…
A developer built AgentGrove, an open-source local workspace that lets users run AI coding agents in parallel on isolated branches with a unified UI. The tool launches existing agent CLIs like Claude …
Elevare Digital's autonomous AI system ARIA silently stopped processing jobs because a Postgres Row-Level Security policy filtered out all rows without raising an error, making an empty queue indistin…
A24 Labs released puffgres (beta), a logical replication service that mirrors Postgres entities in turbopuffer, eliminating data drift by making Postgres the source of truth and automatically syncing …
A developer proposes an analytics API backed by a semantic layer as a unified query interface for metrics, replacing custom endpoints that lead to metric drift and combinatorial explosion. The post in…
Bonnard released @bonnard/mcp-charts, an open-source npm package that lets MCP servers return interactive charts directly in AI clients like Claude and ChatGPT. The tool replaces the common pattern of…
After four attempts and spending $100,000, a team led by an unnamed developer and Jason Seibel succeeded in using Anthropic's Opus AI model to rewrite PostgreSQL in Rust, producing pgrust — 1.8 millio…
