BlackBerry pivots to auto software, QNX now runs in 275 million vehicles

BlackBerry's business today centers on secure government communications and its QNX operating system, which powers safety-critical functions like braking and driver assistance in 275 million cars worldwide. CEO John Giamatteo described the shift from the company's smartphone era on a CNBC podcast, positioning BlackBerry as an embedded software provider rather than a device maker.

Science writer debunks Hollywood's flat, circular wormhole visuals as physically wrong

An essay dissects the common sci-fi trope of depicting wormholes as flat, circular portals with tunnel-like interiors resembling a hole dug by a worm. The author explains that this image stems from misreading two-dimensional diagrams of Einstein-Rosen bridges, which were never meant to represent how a real three-dimensional wormhole would actually appear to an observer.

ButterflyMX founder says AI hiring priority is system-design skill

ButterflyMX founder argues that as AI automates routine execution, companies should prioritize hiring people who can design and improve workflows rather than just perform tasks. He says traditional hiring focused on whether someone could do a job, but AI's ability to scale execution now makes builders who can refine processes and teach AI quality standards more valuable.

Testing shows 8x RTX PRO 6000 rigs excel at parallel serving, not giant model sharding

Jerry James benchmarked an 8-GPU NVIDIA RTX PRO 6000 Blackwell system paired with an AMD EPYC 9555 CPU, offering 768GB of combined GDDR7 memory. Rather than splitting huge models like Llama-3.1 405B or DeepSeek-R1 671B across all eight PCIe cards, which introduces heavy latency, the team found the setup performs best running independent single-GPU model instances in parallel.

Mathematicians resolve long-standing 'sharpness conjecture' in percolation theory

Researchers have completed a proof of the sharpness conjecture for percolation on infinite transitive graphs, closing a problem that mathematicians including Itai Benjamini and Oded Schramm had pursued for decades. The result establishes how quickly phase transitions occur in these systems, confirming that above the critical threshold the connected structure behaves like a vast, dominant network rather than scattered isolated clusters.

Cramer Defends Tim Cook's Legacy as He Steps Down as Apple CEO

Jim Cramer praised outgoing Apple CEO Tim Cook, arguing he has been unfairly overshadowed by Steve Jobs despite delivering massive shareholder returns. Cook officially transitions to executive chairman on Tuesday, handing the CEO role to hardware chief John Ternus, after Apple's market cap grew from about $350 billion to over $4.7 trillion during his 15-year tenure.

Apple releases macOS 27 Golden Gate developer beta 8

Apple has issued the eighth developer beta of macOS 27 Golden Gate, continuing its weekly test cycle ahead of the operating system's public launch. This build appears focused mainly on bug fixes and performance tweaks rather than new visible features, following earlier betas that introduced redesigned Liquid Glass-style traffic light controls.

Apple ships iOS 27 beta 8 with rebuilt Siri AI ahead of September launch

Apple has released the eighth developer beta of iOS 27, its most AI-centric iPhone update yet, available now to Program members via Settings. The update centers on Siri AI, a rebuilt assistant using new Apple Foundation Models that adds richer conversation, on-screen awareness, and deeper app actions, alongside a refreshed Dynamic Island interface and a standalone Siri app. Apple Intelligence features are also expanding into Photos, Safari, Mail, Messages, and other apps as the company nears a public rollout in the coming weeks.

Cronos blockchain back online after $74M Tectonic lending exploit

An attacker manipulated the price of Tectonic's TONIC token by 100x in just 20 minutes, using the inflated collateral to borrow $74 million on the Cronos network. Only about $6 million in Ethereum was actually withdrawn before Cronos halted the chain, with the remainder of the funds left stranded. Cronos validators froze operations, rolled back the chain state to before the exploit, and resumed block production hours later.
