Good morning.

ESP32 can now run in your browser, and you don’t need a dev board.

Embedded

ESP32 firmware runs in-browser

Run chips without hardware: Esp32sim lets you load ESP32 binaries straight into a web page, emulating the MCU entirely in JavaScript.

Why it mattersYou can prototype IoT code instantly, no soldering required.

AI Tools

Test LLM speed before buying hardware

Bench local models instantly: Llmspeed measures inference latency on your machine, so you know if a new GPU will actually speed up your workload.

Why it mattersAvoid overpaying for specs you won’t use.

Search

Code search cuts token use tenfold

Search smarter, not harder: XERJ indexes code, docs, logs and PDFs using 40× fewer tokens than grep and promises up to 10× lower infra costs versus ElasticSearch.

Why it mattersLower token budgets mean cheaper RAG pipelines.

Quick hits

Catch you tomorrow, and keep hacking.
