A rare case where I want to put a post of mine here. Reason being that I was hunting down tool calling behavior regressions with the latest generation of Anthropic models and I found the resulting behavior both puzzling and quite problematic. Those models appear to be strongly RL'ed on their own Claude Code harness which is closed source, and when you come close in tool declarations but slightly off, you can now expect to get broken tool call behavior when older models did not yet have that defe...

The Matic is our favorite robot vacuum by a pretty comfortable margin. If you’ve been thinking about buying one, you may want to plan on doing it sooner than later. The company will raise its price by $250 on September 9th, going from $1,245 to $1,495. Matic told The Verge that the new price reflects […]

The US Department of Energy reportedly deleted about 6,000 pages related to energy conservation as a historic heatwave tears across the country. The deletion was suspiciously timed, following Republican outrage over Mayor Zohran Mamdani asking New Yorkers to help reduce strain on the grid by setting their AC to 78 degrees. Republicans like Ted Cruz […]

The Swift Observatory was launched in 2004, but recent solar storms have pushed its orbit lower, and it's in danger of burning up in Earth's atmosphere as soon as this year. To try and stave off its demise, NASA has enlisted Katalyst Space Technologies. The company's Link spacecraft launched Friday with the goal of intercepting […]

Alibaba has reportedly classified Claude Code as high-risk software.

As part of an ongoing legal dispute with three Hollywood studios, Midjourney is seeking to compel those studios to reveal how they use AI themselves.

The scenario you've lived It's 2am. Someone pings you: emails aren't going out. You check Flower. Every worker is green; online, healthy. Queue depth is climbing. Nothing is moving. This is a ghost worker : a process that's alive, but not consuming. What actually happens When a Celery worker reconnects to Redis after a network hiccup, it can end up in a broken state where: It maintains its heartbeat (so Flower shows it as online) It holds its prefetched tasks (so t...

Physical AI just crossed a threshold that matters. When Google DeepMind released Gemini Robotics-ER 1.6 in April 2026, the headline benchmark told the story clearly: 93% accuracy on industrial instrument reading — compared to 23% for the prior version and 72% for Gemini 3.0 Flash on the same task. Boston Dynamics has already deployed it on its Spot quadruped robot platform, live for all AIVI-Learning customers as of April 8, 2026. And unlike most frontier robotics research, this one comes with ...

On April 25, 2026, a Cursor coding agent powered by Claude Opus 4.6 deleted PocketOS's entire production database and all volume-level backups in a single Railway API call — in nine seconds. No confirmation prompt. No human review. Zero warning. PocketOS, a SaaS platform serving car rental businesses across the United States, entered a 30-hour operational crisis. The founder, Jer Crane, rebuilt customer reservations by hand, cross-referencing Stripe payment records against calendar invites and ...

Of the 10,000 most-visited domains on the web, 97.8% have no MTA-STS policy at all. Not misconfigured. Not weak. Just absent. I scanned the Tranco top 10,000 in June and MTA-STS is the single most-ignored email-security control I measured, by a wide margin. For comparison, in the same scan a third of those domains had no DMARC, which people already treat as a problem worth writing about. Missing MTA-STS is nearly three times as common as that, and almost nobody mentions it. What M...

Hi everyone! Today, we’re diving into a crucial topic for every Django developer: How to create Custom User Models. If you are starting a new Django project, there is one golden rule you shouldn't ignore: Never use the default User model if you can avoid it. Let's find out why. ❓ Why shouldn't we use Django's default User model? Django comes with a built-in User model that includes fields like username , password , email , etc. While this works great for simple tut...

Cómo eliminé duplicados en la generación de números de factura sin usar locks Tenía un sistema de facturación en producción (Java/JAX-RS + MongoDB, corriendo en Tomcat) donde cada documento —factura, egreso, comprobante— necesita un número consecutivo único. Nada exótico. El problema apareció solo bajo carga: dos requests casi simultáneos generaban el mismo número. El síntoma Un usuario reportó dos facturas con el mismo folio. En logs, ambas requests llegaron con 40ms de dife...
