One question I get surprisingly often is: "How do you manage thousands of AI prompts without losing track of them?" The answer is simple. I don't treat prompts as conversations. I treat them as reusable software assets. Over the years, I've created prompt libraries across multiple AI projects, books, research initiatives, and client work. That means managing well over 10,000 prompts covering everything from Python development and AI agents to content generation and workflow auto...

Spanlens is an open-source (MIT) LLM observability platform that lets developers monitor every call their application makes to OpenAI, Anthropic, Gemini, Mistral, OpenRouter, Azure OpenAI, or a local Ollama model. Integration takes one line: swap your client's baseURL to the Spanlens proxy, or run "npx @spanlens /cli init" and the wizard rewrites your code automatically. From that moment, every request is recorded with its model, token counts, latency, cost, and full prompt and response body, w...

Spent the week deep-diving into my dev-publish tool, focusing on durability and orchestrator resilience. 21 commits across two repos, with a massive cleanup of the publishing logic and some much-needed architecture documentation. TL;DR There is a specific kind of satisfaction that comes from taking a tool you use every day and finally giving it the "production-grade" treatment it deserves. This week was exactly that. I spent most of my time in the guts of dev-publish , moving ...

Seven days of flow. Fixed a peer identity binding issue in py-libp2p, automated my Neovim lockfile merges, and added a massive batch of notes on xv6 and Category Theory. 10 commits and a solid PR in the works. TL;DR I managed to hit a perfect seven-day streak this week, balancing some deep-dive p2p networking work with necessary maintenance on my local environment. The highlight was opening a PR in py-libp2p to tighten up how PeerRecords are handled in the Kademlia DHT. On th...

Florida, United States/July 1st, 2026, Chainwire/--Buying gold has long meant choosing between two inconveniences: take physical delivery and pay to store and insure it, or buy a fund and accept the fees and market-hours trading that come with it. A run of moves by Streamex Corp. (NASDAQ: STEX) is aimed at dissolving that trade-off, and the latest landed on June 29, when the company announced its gold-backed, tokenized yield-bearing security $GLDY can now be bought through an ordinary bro...

Zero-Knowledge Proofs (ZKPs) let an untrusted proved show that computation was executed correctly without revealing the inputs to the verifier. However to prove anything, the computation first has to be expressed as a circuit: a system of polynomial equations (constraints) over a finite field. Circuits are the assembly language of zk and every constraint costs prover (and sometimes verifier) time, so production circuits are aggressively hand-optimized. Over the last months, we have been experim...

You Don't Need MIDI-OX Anymore: Building a SysEx Librarian with the Web MIDI API If you own a Yamaha DX7 or a Roland Juno-106, you already know the ritual. Install a utility from 2003. Fight USB-MIDI drivers on Windows 11. Open MIDI-OX. Configure ports. Pray the SysEx buffer doesn't choke mid-dump. Save a .syx file with a name like backup_final_v3_REAL.syx . Lose it anyway. I built knob.monster to kill that ritual. It's a browser-native cloud librarian: plug in your synth, capture...
