New Analysis Revisits Copernicus to Explain Cosmic Expansion Puzzle

A new piece traces how Copernicus's heliocentric model, despite its own flaws, replaced a patchwork geocentric system by offering a simpler explanation for planetary retrograde motion. The author uses this history as a lens to explore why the universe expands, suggesting that today's cosmological models may face a similar shift once a deeper underlying framework is found. The discussion draws parallels between Copernicus's incomplete but directionally correct theory and the current search for a fuller explanation of cosmic expansion.

Startup founder argues AI's real value is eliminating repetitive admin work, not replacing legacy CRMs

An entrepreneur whose company works with university admissions teams describes discovering that staff didn't want a new CRM to replace tools like Slate or Salesforce, but relief from hours spent on manual tasks such as sorting emails, downloading transcripts, and cross-checking student records across systems. The piece argues that this hidden, repetitive work—not the underlying software—is the true source of workplace friction.

Sliding Pizza Peels: A $26 Amazon Gadget Put to the Test

CNET reviewed a low-cost sliding pizza peel, a wooden board fitted with a manual conveyor belt made of nonstick, fiberglass-like material rather than actual cloth. Instead of shoving a rigid peel entirely under a raw pizza, users only need to get the leading edge under the dough before pulling the conveyor toward themselves to load it, then reversing the motion to launch it into the oven.

Nvidia's Jensen Huang argues against AI regulation, calls safety an 'engineering problem'

Nvidia CEO Jensen Huang said artificial intelligence does not require new laws or government oversight, arguing instead that decisions on releasing AI products should rest with the executives running AI companies. His comments came at a Salesforce conference in San Francisco, amid mounting warnings from other industry figures about AI's potential dangers to humanity.

VPN kill switches explained: how they stop IP leaks when connections drop

A kill switch is a VPN feature that watches the encrypted tunnel between a device and a VPN server, cutting internet access the moment that connection weakens or fails. This stops a device's real IP address or DNS requests from leaking during outages or server switches, restoring access automatically once the secure tunnel resumes. The feature comes in two forms: app-level, which blocks only chosen programs, and system-level, which halts all network traffic on the device.

Apple Music's Lossless streaming can be tuned to save cellular data

Apple Music lets users set separate audio quality levels for cellular, Wi-Fi, and downloads within iPhone Settings under Apps > Music > Audio Quality. This allows listeners to save mobile data by keeping cellular playback at High Quality while reserving Lossless streaming for Wi-Fi or downloaded files. Bluetooth headphones don't support true lossless playback, and Hi-Res Lossless requires an external DAC for sample rates above 48kHz.

Explainer: How AI works and why experts are raising alarms over its risks

Artificial intelligence now underpins everyday tools, from curating social media feeds to identifying people in photos and speeding up medical research. The growing popularity of chatbots such as OpenAI's ChatGPT has intensified scrutiny of AI's energy consumption, ethical pitfalls and handling of personal data. Warnings that increasingly capable systems could eventually pose a danger to humanity have fueled demands for stricter oversight and a more cautious pace of development.

MSI interrupt mode explained: why it steadies GPU performance, not speed

MSI (Message Signaled Interrupts) lets a device like a GPU notify the CPU of an interrupt by writing to a memory address rather than fighting for space on a shared physical hardware line. Windows 10 and 11 default to MSI-X, an expanded version introduced with PCI 3.0 in 2010, whenever a device supports it. This approach labels each interrupt with its source, avoiding the collisions that can occur on crowded shared IRQ lines.
