Sharge has released the Shargeek 300, a metal unibody power bank with a 24,000mAh battery that outputs up to 300W, enough to charge two laptops and a phone simultaneously. It features a translucent housing with RGB lighting, a 1.9-inch display showing real-time charging data via its Sentinel battery management system, and is currently priced at $199 through a launch deal on Amazon.
The piece traces why colors, historically described with only a handful of words per language, needed a numerical system for accurate reproduction across billions of screens. It explains that mapping shades to numbers, rather than an ever-expanding list of names, allows for the precision required to distinguish nearly identical hues.
The creator of the posuto package describes how Japan Post's official postal code CSV file breaks basic data conventions, embedding human-readable parenthetical notes that reference row order and splitting overly long fields across multiple duplicated lines. These quirks stem from the file's origins as a printed reference rather than a machine-readable dataset, forcing developers to write extensive workaround logic just to extract clean address data.
Kurt Polzin, chief engineer of NASA's space nuclear propulsion project, and Robert Schleicher of General Atomics Electromagnetic Systems roughed out a nuclear rocket engine design on a napkin during a conference conversation last year. The concept remains at an early paper-planning stage, following a long tradition of major technical breakthroughs first appearing as napkin sketches, from Compaq's portable PC to Vishay's power resistor.
Japanese researcher @dydt_Nao successfully demonstrated a dinner-plate-sized USB flash drive built from magnetic core memory, transferring both a text file and a small monochrome bitmap image between two PCs. The device, which uses a Raspberry Pi Pico as its controller, stores only 128 bytes of data and displays activity through a 32x32 LED array that lights up as each magnetic core is accessed. The creator plans to showcase the device at Maker Faire Tokyo 2026 in early September.
The magic eye tube, invented by Allen B. DuMont in 1932, was a vacuum tube used to visually indicate signal strength in radio receivers, helping users tune into stations accurately. RCA released the first commercial version, the 6E5, in 1935, and these tubes remained common in radios until around 1980, when transistors replaced vacuum tube technology.
Researchers analyzing blood samples from 17,710 people found that those with the highest xylitol levels were 57% more likely to die or suffer a heart attack or stroke within six years than those with the lowest levels, with elevated risk persisting for decades. The findings, presented at the European Society of Cardiology's annual congress in Munich, showed a dose-dependent relationship between xylitol blood levels and cardiovascular events.
Formula E CEO Jeff Dodds reflects on the racing series' evolution from a fledgling 2014 championship, where cars needed mid-race swaps to finish, into a global motorsport with vehicles exceeding 200 mph. Dodds, a former Volvo and Honda motorsport executive, frames Formula E as both a competitive sport and a real-world laboratory for electric vehicle technology, noting it remains the only sport certified as a B Corporation.
Chinese robotics firms are building humanoid and industrial robots using Nvidia's chips and simulation software, an area of AI hardware trade that remains largely permitted under current U.S. export rules. Nvidia has positioned itself as a key infrastructure provider for this 'physical AI' sector, supplying both computing power and development platforms to Chinese customers despite broader U.S.-China tech tensions.
OpenAI announced it will end Cursor's access to its AI models by November 12, 2026, following SpaceXAI's acquisition of the coding assistant. The company said Cursor may set an earlier cutoff date if it prefers, but OpenAI will not extend access beyond that deadline.
Apple is preparing to release its first smart glasses as early as next year, built around Siri and Visual Intelligence rather than augmented-reality displays. The glasses will use cameras and microphones to let Siri interpret surroundings, translate text, and answer contextual questions, plus built-in speakers for audio, according to a Bloomberg report citing Mark Gurman. Apple is designing multiple frame styles in-house using acetate material, with possible future versions adding health-tracking features like heart-rate sensors.
The report clarifies that caches are temporary storage used by browsers and apps to avoid re-downloading or recreating data like images, playlists and thumbnails. It notes there is no single universal cache on a device, since browsers, individual apps and the system each maintain separate caches for different purposes.
