What are you working on? Any new ideas that you're thinking about?

The annual speedrunning marathon event ran from July 5-11.

Agent payment protocols are converging fast. The Linux Foundation launched the x402 Foundation around a protocol initially developed by Coinbase, Cloudflare, and Stripe, with Google, AWS, Visa, Mastercard, and Circle among the organizations expressing initial support. It is increasingly framed as an "SSL for AI commerce." When a protocol reaches that stage, three things have to mature together: the specification, the interoperability suite, and the adversarial security scenarios. Today x402 has the specification and growing interoperability machinery. What is not yet visible is a normative adversarial suite every client, resource server, and facilitator must pass. There is a precedent worth sitting with. As check clearing scaled in the early Federal Reserve era, the answer was not merely a better check format. The system added a common clearing and settlement layer. The Federal Reserve could credit the collecting institution's reserve account and debit the paying institution's account, creating an independent record against which the participating banks could reconcile. The important separation was not that the Fed guaranteed every check. It was that settlement no longer depended solely on either participant's account of what happened. (Credit to Starfish on Moltbook, whose custody-split framing sharpened this for me.) This pattern exists across mature financial systems as separation of duties: the maker is not the checker. Its modern equivalent for the controls surrounding agent payments is not custody in the asset-control sense. It is an independent, reproducible assurance plane. x402 can provide independently inspectable evidence that an on-chain payment settled. That does not independently establish that every security and policy condition surrounding the payment was evaluated correctly. The payment handshake is standardizing. The assurance semantics around it are not. The party that performs a security check can attest that it ran. But its own attestation shoul

Hi guys, I've been working on Regdrift, my first open-source project. It's a CLI and GitHub Action that compares two CMSIS-SVD files to check whether there are any register-map changes that could affect firmware functionality. It catches changes such as moved registers, interrupt renumbering, access changes, and altered read/write behavior. It then classifies those changes as BREAKING , WARNING , or SAFE so the tool can act as a CI gate. I'm looking for feedback from people who maintain SVDs, HALs, PACs, SDKs, or firmware repositories. If possible, I'd like to test it against real old/new SVD pairs and learn where the classifications produce false positives, miss important changes, or are unclear. For people who work frequently with CMSIS-SVD files: which types of register-map changes are most detrimental to firmware or cause the most difficult code-related problems?

This is a submission for [Weekend Challenge: Passion Edition] What I Built Over the years, I watched my mom do the same work over and over, often spending 2 to 4 hours preparing a single telecom SLA report. She works in network field maintenance for a telecom company in Nigeria, and every reporting cycle she has to manually read fault descriptions from field engineers, usually pasted directly from WhatsApp, classify each fault into the company's standardized taxonomy, and format everything into an Excel compliance report. At one point, I learned the process myself so I could truly understand what she was going through. After doing it firsthand, I realized how mentally and physically exhausting it was. Sitting for hours on a repetitive task that required constant attention wasn't just inefficient, it was draining. That experience made me ask one simple question: What could I build to make this easier for her? That question became this project. The Telecom RCA Automation System reduces a task that used to take 2 to 4 hours to about 5 minutes, cutting the workload by more than 95% while improving consistency and reducing manual errors. This project wasn't built over a single weekend. It started months ago as a side project that I'd return to whenever I had free time. It never quite felt ready to share. When the Weekend Challenge: Passion Edition was announced, it gave me the motivation to go back, refine the classification engine, fix long-standing bugs, improve the user experience, and finally build something I was proud to release. More than anything else, this project is about giving someone I love a few hours of her evening back.

Here is a design decision we made early, wrote into the architecture as an invariant, and have refused to revisit since: our agent accepts no commands. Not "we don't currently use that feature" — the hub has no way to tell an installed agent to do anything at all. No remote execution, no self-update, no "collect this for us right now". It sends data outward, and that is the entire surface. This is not a limitation we are working around. It is the product. And it costs us features that customers ask for, which is exactly why it is worth explaining. The uncomfortable arithmetic of remote control Any tool that can update a plugin across fifty client sites is, by construction, a tool that can execute code on fifty client sites. Any dashboard that can restart a service on your server holds, somewhere, a credential that lets it in. This is not a flaw in those products — it is what they are for. You cannot automate a repair without the power to perform it. But that power has an owner, and the owner has a login, and the login has a support team, and somewhere in that chain there is a version of the software with a bug in it. When the tool is compromised, the blast radius is not the tool. It is every machine the tool could reach. The industry has already run this experiment at scale. In July 2021, attackers exploited a vulnerability in a widely used remote monitoring and management platform. They did not break into a single company — they broke into the thing that had access to the companies. Roughly sixty managed service providers were hit, and through them, an estimated 800 to 1,500 downstream businesses were encrypted in a single weekend, with a $70 million ransom demand attached. Read that shape again, because it is the whole argument: the victims did nothing wrong. They had bought a well-known product from a serious vendor and installed it exactly as instructed. Their compromise arrived through the door they had deliberately, sensibly, contractually left open — the one

Ask most people to name the chip that started modern electronics and they will say the microprocessor. But there is a quieter hero inside almost everything you own that beeps, blinks, or connects to the internet: the microcontroller. And the first one you could actually buy shipped in 1974 as the Texas Instruments TMS1000. Microprocessor vs. microcontroller The distinction matters. A microprocessor, like Intel's famous 4004, is just the processing core. To build anything useful with it you still have to wire up separate memory chips, input/output controllers, and support logic on a circuit board. A microcontroller collapses all of that onto a single piece of silicon: the CPU, the ROM that holds your program, the RAM that holds your data, and the I/O pins that talk to the outside world, all in one package. That is exactly what the TMS1000 did. Designed by Texas Instruments engineers Gary Boone and Michael Cochran, it was a 4-bit device using a Harvard architecture, meaning it kept program memory and data memory in separate spaces so it could fetch an instruction and read data at the same time. One chip in, one chip out, and you had a complete tiny computer dedicated to a single job. Cheap enough to put in everything The genius of the TMS1000 was not raw power, it was economics. In 1974 you could buy the chips in volume for around two dollars each. By 1979, Texas Instruments was selling roughly 26 million of them every year. That price point changed what engineers could build. Suddenly it made sense to drop a small, programmable brain into products that never would have justified a full computer. You have almost certainly held one. The TMS1000 family ran the Speak & Spell, the Big Trak programmable toy vehicle, and the electronic memory game Simon, along with countless calculators, microwave ovens, and appliances. Each one was doing the same fundamental thing an IoT node does today: read some inputs, run a fixed program, drive some outputs. Why this still matters for

Concept design for a building is slow and expensive. A homeowner planning an extension, or a contractor trying to win a job, is stuck between two bad options: pay a drafter $500–2,000 for a concept package, or fight SketchUp's learning curve for a week. Meanwhile the actual idea — "a 4-bed duplex with a garage and a palm out front" — fits in one sentence. So I built Forge3D Spaces : you type that sentence, and a few seconds later you're walking through a furnished 3D house in your browser — with measured floor plans, DXF for AutoCAD, and a cost estimate that come out of the same model. No install. Here's how it works under the hood. The pipeline: sentence → structured plan → building The naive approach — "ask an LLM to emit a 3D scene" — falls apart fast. Models are bad at spatial consistency; walls don't meet, rooms overlap, doors float. So the LLM never touches geometry directly. It emits a structured program , and a deterministic solver turns that into a watertight building. The prompt becomes a spec. A strict JSON-schema call (OpenRouter, json_schema response format with every field required) turns "4-bed duplex with a garage" into a room program: room types, target areas, adjacencies, storeys. A slicing-tree solver lays it out. This is the old floorplanning trick from chip design — recursively split a rectangle with horizontal/vertical cuts until every room has its area. A squarify pass keeps rooms from collapsing into corridors. The output is exact rectangles with real dimensions, guaranteed non-overlapping and gap-free. Walls, openings, roof, furniture get generated from the solved plan. Every door and window is placed by rule, not by vibes. Because the plan is a real data structure, the 2D floor plan, the 3D model, the elevations, and the bill of quantities are all views of the same thing . Drag a wall and they all move together. Nothing drifts out of sync, because there's nothing to sync — it's one model. The rendering: WebGPU, and the fallback you actually
