Amazon: This week’s AWS outage caused by major DNS failure

Amazon says a major DNS failure was behind a massive AWS (Amazon Web Services) outage that took down many websites and online services on Monday.

As BleepinComputer reported earlier this week, this incident impacted a critical Northern Virginia data center in the US-EAST-1 region, affecting users worldwide, including the United States and Europe, for over 14 hours.

According to a post-mortem published on Thursday, a race condition caused a major DNS failure in Amazon DynamoDB’s infrastructure, specifically within its DNS management system that controls how user requests are routed to healthy servers, which led to the accidental deletion of all IP addresses for the database service’s regional endpoint.

Open letter calls for prohibition on superintelligent AI, highlighting growing mainstream concern

An open letter released Wednesday has called for a ban on the development of artificial intelligence systems considered to be “superintelligent” until there is broad scientific consensus that such technologies can be created both safely and in a manner the public supports.

The statement, issued by the nonprofit Future of Life Institute, has been signed by more than 700 individuals, including Nobel laureates, technology industry veterans, policymakers, artists, and public figures such as Prince Harry and Meghan Markle, the Duke and Duchess of Sussex.

The letter reflects deep and accelerating concerns over projects undertaken by technology giants like Google, OpenAI, and Meta Platforms that are seeking to build artificial intelligence capable of outperforming humans on virtually every cognitive task. According to the letter, such ambitions have raised fears about unemployment due to automation, loss of human control and dignity, national security risks, and the possibility of far-reaching social or existential harms.

https://lnkd.in/gUDFq8KF Explicit solution of Navier Stokes Equation A millennium problem! can we prove that fluid motion always stays smooth, or can it blow up into chaos?

Here’s the equation that rules all fluids: ρ (∂u/∂t + (u·∇)u) = −∇p + μ∇²u + f What it means: — u: velocity field (how the fluid moves) — p: pressure — μ: viscosity (internal friction) — ρ: density — f: external forces (like gravity) Instead of solving the velocity u directly, he treats the fluid like a symphony of interacting notes: φ(x, t) = ∫ d³k [ aₖ e^(-iωt + ik·x) + aₖ† e^(iωt — ik·x) ] Each aₖ and aₖ† represent creation and annihilation operators — the conductors of the quantum orchestra of sound. 🎵 Analogy: Fluid as a Symphony Imagine a calm pond. Every ripple is a gentle musical note. Now drop many stones — the ripples overlap, collide, and amplify. That’s turbulence.

One Mind, Two Bodies: Man With Brain Implant Controls Another Person’s Hand—and Feels What She Feels

It sounds like science fiction, but the system could boost collaborative rehabilitation, where groups of people with brain or spinal cord injuries work together. By showing rather than telling Denapoli how to move her hand, she’s nearly doubled her hand strength since starting the trial.

“Crucially, this approach not only restores aspects of sensorimotor function,” wrote the team. It “also fosters interpersonal connection, allowing individuals with paralysis to re-experience agency, touch, and collaborative action through another person.”

We move without a second thought: pouring a hot cup of coffee while half awake, grabbing a basketball versus a tennis ball, or balancing a cup of ice cream instead of a delicate snow cone.
