TikTok backed out of a congressional committee's "public roundtable" set for this month over concerns it would be asked about child safety practices, the chair of the committee said. After negotiating "in good faith" to bring TikTok's chief security officer before the House Select Committee on China to answer questions about Chinese government access to […]

The family-focused AI assistant wants access to the details of your everyday life, but says it won’t use that data to train AI models or share it with others.

The Circular Ring 3 series announcement comes amid a year of heightened competition in the smart ring market, following the launches of the Oura Ring 5 and RingConn Gen 3.

Ultrahuman is targeting a $200 million annual revenue run rate by January 2027 as it builds a new Qualcomm-powered smart ring.

OpenAI claims that Astra represents "a new frontier on computer and browser use," and that it handles tasks with unmatched "speed, accuracy, and safety."

For its new Muse Spark model, intended for operating coding and other agents, Meta is offering an explicit discount averaging out to about 95% for users who "contribute" to the development of future models by sharing their prompts and model outputs.

Abliteration.AI is making powerful AI models without guardrails easier to access, arguing that giving defenders the same tools as bad actors could ultimately improve cybersecurity.

The grid has been straining under the weight of new AI data centers, and that has utilities courting fusion startups.

The high-profile startup's annual revenue run rate stands at at over $100 million.

The company is about to formally launch the gold two-seater, with no steering wheel or pedals -- a move that could change Tesla forever.

The current generation of AI coding agents makes it surprisingly easy to create a "skill." Write a Markdown file. Add instructions. Give it a name. Put it inside .claude/skills/ . Done. Except it isn't. As soon as you build more than a handful of skills, a different set of problems appears: Which skill should activate? Why did two skills activate at the same time? Why did the agent ignore an important instruction? What belongs in a skill versus a rule, agent, hook, or script...

Your app works. Then a user opens it in a second tab, and things start going wrong in ways that never show up in testing. Both tabs poll the server, so your request volume doubles for one user. Both hold a WebSocket, so your connection count is wrong and your server thinks you have twice the traffic you do. Both raise the same desktop notification, so it appears twice. The user signs out in one tab and the other carries on as though nothing happened, still showing their data, still refre...

The current AI coding discussion spends too much time asking which model is “best.” I think that framing is already becoming obsolete. There may be a best model for a particular benchmark, but software engineering is not one task. It is a pipeline containing planning, repository exploration, implementation, debugging, documentation, testing, validation and adversarial review. Why should every stage use the same model? My current approach is to treat models like members of an engineer...

It Compiled. It Ran. Nothing Got Written. Diagnosing a CA 2E-generated program that returns clean, throws nothing, and still doesn't do the thing — and why calling it directly is not the same test as running it for real A compile error is, in a strange way, the easy case. The compiler stops you, points at a line, and you fix it before anyone downstream ever sees the problem. What actually costs people time on CA 2E work isn't the 1,600-message compile listing — it's the progr...

In 5G, the gNB is not a single box. Under the 3GPP higher-layer split (TS 38.401), a Central Unit owns the upper radio-protocol layers, and one or more Distributed Units own the real-time lower ones — RLC, MAC, and PHY. F1-U is the user-plane leg between them, and it carries GTP-U tunnels running the NR User Plane Protocol (NR-U / NRUP, TS 38.425). The CU-UP pushes downlink data toward a radio it cannot see; the DU reports back what it managed to send. This walkthrough reads a real srsRAN F1-...

MCP Design Patterns: Building Scalable AI-Integrated Systems in Java A comprehensive guide to seven proven architectural patterns for Model Context Protocol servers, with production-ready Java implementations. The 7 Essential MCP Patterns Pattern 1: Resource Provider Pattern Abstracts heterogeneous data sources (databases, files, APIs) behind a unified interface. Create a ResourceProvider interface that any data source can implement. Use when : Multiple d...

Notes to my future self, in plain English. What I Was Trying To Do I already had my portfolio website working on my computer using Hugo and a template for the design. I wanted to package it up in Docker so I could run it the same way anywhere, instead of relying on my machine's setup. Lesson 1: Hugo Doesn't Actually "Run" a Website When I ran hugo server on my computer, it felt like a website was "running." But that command is really just a preview too...

When building conversational agents or real-time voice applications, latency is the defining metric. If Time-to-First-Byte (TTFB) exceeds 200ms, natural turn-taking breaks down and conversational interruption becomes clunky. We recently recorded and aggregated median latency and pricing metrics across the primary streaming Text-to-Speech APIs using WebSocket connections (US-East endpoints, median across 1,000 requests). Summary Table Provider Model TTFB Latency Pr...

EF Core 10 named default constraints solve an annoying SQL Server maintenance problem: database-generated names such as DF__Jobs__Status__... are hard to predict in scripts and incident playbooks. The new convention gives every default a stable name. The catch is easy to miss: enabling it on an existing model makes the next migration change every default constraint in that model. That is exactly the kind of small configuration edit that deserves a migration gate. I want to know how many col...

WebSocket is a communication protocol that enables full-duplex, bi-directional communication between a client and a server over a single, persistent connection built on top of TCP. Unlike the request-response model that defines regular HTTP traffic, where the client must always initiate every exchange and the server can only reply when asked, WebSocket keeps the connection open once it is established, so either side, the client or the server, can send data to the other at any moment, without wai...

Have you ever shipped a refactor that looked smaller than a coffee run and then spent two days proving Python can lie? I asked a free model to lift a handful of dataclasses out of a growing worker module. It did the extraction cleanly enough, except it named the new file types.py , which is a loaded word in this language. Local pytest stayed green. The same tree on a free server started failing on an import that I did not even touch. I was comparing those two environments with MonkeyCode bec...

Agricultural businesses can look simple from the outside. A farmer grows a crop. The produce is harvested, processed, packaged, and sold. But once an agricultural business operates at scale, the process becomes considerably more complicated. There may be hundreds of farmers, multiple regions, crop cycles, planting inputs, quality inspections, warehouses, production stages, customer-specific product variants, sales orders, and export requirements. Meru Greens Horticulture in Kenya pro...

These are my notes from porting my Amiga game, which I originally built in Baghdad in 1993 in MC68000 assembly, to Godot, using Claude Fable 5 during last July holiday. It took an evening! Getting the feel right and shipping it took a few more weekends and evenings. I spent the last few weeks analyzing what Claude did, feeding it my 33 years of memory of how I built the game, my notes and the git repos. It wrote the first draft of the article, and I edited line by line over a week. The screensh...
