Detecting AI Agents in Your Codebase
A 3-tier detection hierarchy: Co-Authored-By commit trailers, environment variables (CLAUDE_CODE, CURSOR_SESSION), and TTY heuristics for identifying AI-generated code changes.
RAG Pipeline: Document Search With pgvector and Semantic Chunking
PostgreSQL with pgvector for embeddings, Datalab API for semantic chunking, Mistral Reranker for top-k refinement, and context compression at 150K tokens.
Generating PDFs, Spreadsheets, and Slide Decks From a Chat Message
Six file generation tools: XLSX, PDF, PPTX, DOCX, HTML, MD. The AI plans the structure, generates via Python libraries, uploads to S3, and streams progress.
From 5 Agents to Production: Shipping 0diff in 20 Minutes
The full story: 5 parallel agents built 0diff in 45 minutes (2,356 lines, 44 tests), then a 20-minute polish session made it production-ready.
AI Memory and Context Compression
Fire-and-forget conversation summarization, the save_memory tool, and context compression at 150K tokens. How the AI remembers across sessions for $0.00005 per summary.
Real-Time File Watching and Diff Computation in Rust
A synchronous event loop with notify, in-memory file caching, the similar crate for structured diffs, and a whitespace filter -- the core of 0diff in 626 lines of Rust.
4 Agents, 1 Product: Building 0cron in a Single Session
How we used a 4-agent parallel team to build a marketing website and a full Rust API server -- 14 endpoints, 8 DB tables, 2,852 lines -- in a single session.
Why the World Needs a $2 Cron Job Service
The cron job market is broken: free tools are unreliable, paid tools start at $19/mo. Here is why we built 0cron at $1.99/mo unlimited from Abidjan.
#034 -- Traits and Interfaces
How we designed FLIN's trait system -- trait declarations, impl blocks, trait bounds on generics, and the Rust implementation that ties polymorphism to type safety.
Automatic SSL: DNS, ACME, and Custom Certificates
How sh0 handles SSL certificates automatically via Caddy's ACME integration, supports custom certificate uploads with AES-256-GCM encrypted private keys, and configures DNS for self-hosted deployments.
Auth in Rust: Argon2id, JWT, TOTP, and API Keys
Building a complete authentication system in Rust: Argon2id password hashing, HS256 JWT tokens, TOTP 2FA with backup codes, API key generation, and AES-256-GCM encryption.
Backup Engine: AES-256-GCM, 13 Storage Providers, and FTP Nightmares
Building a backup engine with pluggable storage, AES-256-GCM encryption, 13 storage providers via OpenDAL -- and the IPv6 FTP bug that forced us to write our own client.
