A researcher built and trained a small transformer model from scratch in 1.5 hours on a single RTX 5090 GPU, achieving 44% accuracy on the ARC-AGI-1 public evaluation set and 7% on ARC-AGI-2. The model, an upgraded and cheaper version of a previous open-source release, matches the performance of existing test-time-training approaches like TRM and HRM while using far less compute.
Over his 15 years as Apple CEO, Tim Cook navigated increasingly tense relations between Chinese President Xi Jinping and US President Donald Trump, helping Apple avoid the worst fallout from a US-China trade war while keeping manufacturing operations in China intact. His approach included storing some Chinese user data on mainland servers starting in 2014, complying with Chinese app removal demands, and staging high-profile displays of goodwill with Trump, such as touring a Mac Pro plant together.
NASA is inviting people to sign up online for a personal 'pixel' from the first images captured by the Nancy Grace Roman Space Telescope. Each participant provides an email address, which is limited to one pixel per address, and later receives a printable certificate showing their assigned pixel number.
A developer examining Git's command-line safety flags found that removing or moving a git worktree containing submodules requires the --force flag, a restriction dating back to git worktree's 2015 introduction. The analysis traces how git worktree add had to be patched to ignore submodule.recurse to avoid corrupting empty submodule paths, and argues that git submodules function as a de facto package manager, with the gitlink SHA acting as a lockfile entry and .gitmodules as the manifest.
Samsung has launched the Galaxy S26 FE with only minor spec upgrades over its predecessor, yet raised the price by $50/£50 for equivalent storage tiers, reportedly due to rising component costs. This narrows the price gap to the flagship Galaxy S26 to roughly $100, while that model offers a stronger chipset and better cameras.
Dyson has unveiled the CameraJet, a $500 toothbrush that combines brushing, camera-guided gap detection, and water-jet flossing in one device. A tiny 0.1-megapixel lens under the brush head works with machine learning trained on 470,000 dental images to spot gaps between teeth and fire small bursts of fluid to floss them in real time. A companion MyDyson app lets users view their mouth live, get brushing feedback, and adjust intensity and jetting modes, though Dyson says no images are stored.
Dyson has introduced the CameraJet, an electric toothbrush that combines bristles with an integrated water flosser guided by a tiny embedded camera. The camera captures 28 images per second to detect gaps between teeth and fires a cone-shaped jet of rinse into them within 100 milliseconds, using a machine-learning model trained on roughly 470,000 dental images gathered over six years of development.
Apple has installed John Ternus, previously its senior vice president of hardware engineering, as chief executive, succeeding Tim Cook as of September 1st. Johny Srouji has been elevated to chief hardware officer as part of the leadership shuffle.
Florida's Department of Transportation issued a memo revoking permits for all automated license plate readers, including those made by Flock, installed on state highways. The agency says operators have 30 days to remove the devices, and it will no longer approve new placement requests on state roadways.
Samsung has rolled out the eighth One UI 9 beta update for the Galaxy S26 lineup, starting with the Galaxy S26 Ultra in South Korea. The 513MB Android 17-based update carries firmware ending in ZZHM and the August 5, 2026 security patch, with the changelog citing only stabilization fixes for device operation. It arrives alongside the first One UI 9 beta for the Galaxy S25 series.
South African carrier Airlink flew two Embraer passenger jets extremely close above DHL Stadium in Cape Town before a Springboks vs. All Blacks rugby match, with one plane reportedly passing within 50 feet of the roof. The stunt, captured widely on social media, alarmed viewers who thought it looked like a near-collision rather than a planned display.
John Ternus took over as Apple's chief executive on September 1, inheriting a fall lineup that includes a foldable iPhone, a new AI-enabled smart display, and an updated Siri platform. He steps into the role while Tim Cook stays on as executive chairman, and while Apple grapples with a memory chip shortage, App Store revenue pressure, staff departures, and an AI program still trailing competitors.
