Singapore's government dating app pilot uses Gale-Shapley matching algorithm

Singapore has piloted FirstDate, a government-run dating app for public servants aged 21-35, built on the Gale-Shapley stable matching algorithm that won the 2012 Nobel Prize in Economics. The app ranks users' preferences, produces one mutually-stable match per cycle with a 72-hour decision window, verifies identity via Singpass, and only reveals contact details when both parties agree.

NRC grants TVA construction permit for BWRX-300 reactor at Clinch River

The Nuclear Regulatory Commission approved a construction permit for the Tennessee Valley Authority to build a GE Vernova Hitachi BWRX-300 small modular reactor at its Clinch River site near Oak Ridge, Tennessee, completing its review 14 months in, four months ahead of schedule. TVA becomes the first US utility cleared to build this reactor design, though it still needs a separate operating license before loading fuel or generating power. TVA is also considering building up to four such units at the site but hasn't set a start date or final cost estimate.

A teardown of Google Photos for Android (v7.95) by Android Authority uncovered a hidden 'Delete all' button for the Remember List, a feature tied to Ask Photos that stores information users share to improve search and editing.

Amazon launches Fire TV Stick 4K that draws power from TV's USB port

Amazon's new $59.99 Fire TV Stick 4K, available now, can be powered directly from a television's USB port instead of requiring a separate adapter. It runs Amazon's refreshed TV OS with Wi-Fi 6 and Bluetooth 5.3, and replaces the previous 4K 'Select' and 'Plus' sticks, trimming the streaming lineup to four devices. Amazon also unveiled a redesigned Fire TV Remote for $14.99, shipping late October, plus Alexa Plus integrations across the Fire TV app and a new Amazon Music app.

Reviewer frees 15GB on Samsung Galaxy using Device Care, Files by Google, and SD Maid SE

An Android Authority writer tested three storage-cleaning tools — Samsung's built-in Device Care, Google's Files app, and the power-user tool SD Maid SE — after nearly filling a 256GB Galaxy phone. The cleanup recovered 15GB, less than hoped, largely because the reviewer chose to keep many large personal files rather than delete them.

Rather than order household goods, several neighbors began sending each other single potatoes and bottles of water via the delivery drones, which carry up to 2.7 pounds and fly a roughly six-mile radius.
