It’s not just you: AI startups are taking in a huge amount of seed funding, and in the process making things harder for anyone looking for funding even at a pre-seed stage. We’ve covered the trend in detail, and at this year’s TechCrunch Disrupt event, we want to help pre-seed founders now being held to seed-stage […]

Build AI agents your whole team can run, and control Discussion | Link

The recall comes as the top automotive safety regulator in the U.S. has warned AV companies about their vehicles interfering with first responders.

Also, we try to make sense of OpenAI's rumored AI smart speaker.

This is Optimizer, a weekly newsletter sent from Verge senior reviewer Victoria Song that dissects and discusses the latest gizmos and potions that swear they're going to change your life. Opt in for Optimizer here. I was in the middle of writing a different Optimizer column this week when I learned that Pete Hegseth is […]

Election deniers have spent years promoting the idea that the 2020 election was stolen. They believe Donald Trump’s speech finally proves them right.

Last year, Microsoft's 13-inch Surface Laptop quickly became one of my favorite thin-and-light Windows notebooks. At $900, it was easy to recommend to anyone wanting MacBook Air-like build quality and battery life on Windows - I even convinced my sister to buy one on sale. But that was last year. This year, thanks to RAMageddon, […]

Ben O'Mahony discusses building custom AI-powered Language Server Protocols (LSPs) that go beyond standard rule-based checkers. He explains how to instrument AI agents natively with OpenTelemetry to track concrete user actions (accepting, dismissing, or regenerating code fixes) as implicit labels, creating a continuous data flywheel to distill frontier capabilities into cheaper, local SLMs. By Ben O'Mahony

Overview lead-quorum was a strong pilot repo because it was small enough to reason about and real enough to fail honestly. It has: repo-local Python environment ownership pinned dependency installation env bootstrap from example truth a deterministic local test surface live external verification a local web runtime a distributed demo path a Docker build lane That is exactly the kind of repo where a contract can look clean while still hiding real setup and execution drift. Why this repo mattered The useful pressure here was not “can Ota run one Python command.” The useful pressure was whether Ota could stay truthful when the repo itself owns: the .venv the dependency install lane the local executable path the runtime listener truth If Ota probes or fulfills those in the wrong order, the contract is not trustworthy even if the repo itself is valid. That is what made lead-quorum valuable. What the contract now models The final contract is explicit about the repo’s real setup split. Setup is not one opaque shell step. It is three different ownership surfaces: copy .env from .env.example only if missing create the repo-local virtual environment hydrate dependencies through typed uv requirements-file installation That looks like this in the contract: setup : aggregate : tasks : - setup:env - setup:venv - setup:deps setup:env : action : kind : copy_if_missing from : .env.example to : .env setup:venv : action : kind : ensure_virtualenv path : .venv python : " 3.12" setup:deps : prepare : kind : dependency_hydration medium : package_dependencies source : kind : uv cwd : . mode : pip_requirements requirements_file : requirements.txt The contract also keeps verification and external-runtime claims separate: verify for deterministic local validation live for Gemini-backed end-to-end testing app for the local web service distributed for the A2A demo path That matters because a working local scoring test and a live distributed runtime are not the same readiness claim.

Modbus RTU over RS-485 is the serial workhorse of industrial field wiring — the variant you'll meet when connecting an ESP32 directly to an energy meter, PLC, VFD, or temperature transmitter over a wired bus. This tutorial walks through wiring the hardware, installing a library, and flashing working RTU master code. What You'll Build A Modbus RTU master on ESP32 that polls holding registers from an RS-485 slave device over a wired bus. An understanding of register types, addressing, and the reliability practices that separate a demo from a production deployment. Prerequisites Arduino IDE (or PlatformIO) with the ESP32 board package installed. An ESP32 dev board, or an industrial ESP32 controller with a built-in RS-485 transceiver such as the NORVI X — this saves you from wiring a separate MAX485 module. A Modbus RTU slave device (energy meter, sensor, or PLC). Basic familiarity with the Arduino C++ syntax and serial monitor debugging. A 60-Second Modbus Primer Modbus is a master–slave protocol dating back to 1979. One master polls up to 247 slave devices, each with a unique address (1–247). Data lives in four register types, and knowing which one you need is half the battle: Register Type Access Width Typical Use Coils (0x) Read/Write 1-bit Relay outputs, digital controls Discrete Inputs (1x) Read only 1-bit Digital sensor inputs, switch states Input Registers (3x) Read only 16-bit Analog sensor values, process data Holding Registers (4x) Read/Write 16-bit Setpoints, configuration parameters Modbus RTU over RS-485 Step 1 — Wire the Hardware The ESP32's UART pins output 3.3V TTL logic, but RS-485 uses a differential voltage signal — so you need a TTL-to-RS-485 transceiver (typically a MAX485 or MAX3485 chip) between the ESP32 and the bus. UART TX → transceiver DI (driver input) UART RX ← transceiver RO (receiver output) A spare GPIO → transceiver DE and RE tied together (direction control) Transceiver A/B terminals → the RS-485 A+/B− pair on your slave device Skip th
