▸ • Microsoft rolls out "Agent Mode" in Office apps, turning Copilot into a proactive collaborator.
▸ • OpenAI makes its specialized ChatGPT for Clinicians free for verified US healthcare professionals.
▸ • Crypto scammers are impersonating Iranian authorities to extort "safe passage" fees from ships in the Strait of Hormuz.
Microsoft is rolling out Agent Mode in Word, Excel, and PowerPoint, allowing Copilot to take multi-step, app-native actions. It's designed to turn passive tools into proactive collaborators, though we're still not entirely sure what "vibe working" actually means.
OpenAI has launched a specialized, HIPAA-compliant ChatGPT for Clinicians and made it completely free for verified US healthcare professionals. The company claims it outperforms human doctors on clinical tasks, even when the humans have unlimited time and internet access.
Elon Musk admitted on an earnings call that millions of Tesla vehicles equipped with Hardware 3 won't actually receive unsupervised Full Self-Driving capabilities. It turns out the compute requirements for true autonomy are a bit steeper than anticipated.
Shade just secured $14 million to help creative teams search their massive video libraries using natural language. It even includes a custom filesystem that lets you stream files directly to your local drive.
Running AI agents locally drains your battery and hits resource limits fast. Bernstein's new architecture moves agent execution to Cloudflare Workers, using Durable Workflows for multi-step tasks and D1 for state, proving that the edge is the perfect place for orchestration.
David Crawshaw is building a cloud from scratch and documenting the journey. It's a fascinating look into the raw infrastructure, networking, and hardware decisions required when you decide AWS is just someone else's computer and you'd rather use your own.
Historically, a panic in a Cloudflare Rust Worker was fatal and poisoned the entire instance. By collaborating upstream on the wasm-bindgen project, Cloudflare has introduced resilient critical error recovery, including panic unwinding using WebAssembly Exception Handling.
A deep dive into the process of writing a C compiler using Zig, exploring the lexical, syntax, and semantic analysis stages. It's a great reminder of the unexpected complexity involved in translating simple C instructions into efficient assembly for small processors.
Scammers are impersonating Iranian authorities over VHF radio and WhatsApp, demanding Bitcoin and Tether from ships stranded in the Strait of Hormuz for "safe passage." It's a wild intersection of geopolitical fog-of-war and modern crypto grift.
Honor has announced the 600 and 600 Pro Android phones, and they look suspiciously familiar. The Pro model even features the exact same triple rear camera and flash layout as the iPhone, proving that imitation is the most profitable form of flattery.
