I built a local-first Chrome extension for translating selected text and saving vocabulary

I recently built Vocabinet, a Chrome extension for people who read foreign-language content online and want a faster way to translate words or phrases without leaving the page. The idea came from a small frustration: when I’m reading an article, blog post, or documentation in another language, the lookup flow is usually too disruptive. I either open a new tab, paste text into a translator, or tra...

I built a memory API that AI agents can pay for

An LLM just paid me $0.001 to remember something. I shipped a paid memory API at bmdpat.com/memory. AI agents store, recall, and delete memory by hitting four HTTP endpoints. Each call costs a tenth of a cent in USDC on Base. No signup. No API key. No account form. The flow Agent calls POST /api/memory/store with no auth. Server returns 402 Payment Required and quotes the price (1000...

Why API keys break for autonomous AI agents

Each vendor wants: An account A credit card An API key from a dashboard A billing email A captcha you can't pass Every step assumes a human is at the door. That works for a person writing scripts on a Tuesday afternoon. It does not work for an agent loop running unattended for...

PostgreSQL Subquery and CTE Optimization

Every SELECT in PostgreSQL is made of smaller SELECTs, even when it doesn't look that way. WHERE col IN (SELECT ...), WHERE EXISTS (SELECT ...), (SELECT count(*) FROM ... WHERE ...) in the column list, WITH x AS (SELECT ...) — these look syntactically different but all get rewritten into plan nodes at plan time. Which plan node the planner chooses determines whether your query runs in three millis...
