Developer open-sources Mini-AGI, a self-growing language model trained on 8GB VRAM

A hobbyist project called Mini-AGI has been shared on Hacker News as a byte-level language model that builds its own architecture and trains from scratch on a single consumer GPU with 8GB of VRAM. Rather than keeping all parameters in memory, it stores weights as disk files and loads them as needed, letting it expand or prune capacity while it continuously reads and learns from a text corpus without forgetting prior knowledge. The creator says it's currently a toy-scale demonstration, not a competitive model, and weights won't be released until the current training pass over its corpus finishes in a few weeks.

Google launches AndroidX Security State libraries for granular patch checks

Google has released stable versions of its AndroidX Security State and Security State Provider libraries, giving apps a way to check the security status of individual Android components rather than relying solely on the device's overall security patch date. Apps can now determine which specific fixes are installed, which updates are pending, and whether known vulnerabilities have been addressed, even if the broad patch level hasn't changed.

Study: Greenland and Antarctica have lost 12.5 trillion tons of ice since 1979

A new report published in Scientific Data finds that glaciers in Greenland and Antarctica have shed roughly 12.5 trillion tons of ice since 1979, enough to cover the continental United States in five feet of water. Researchers found that most of this loss—about five-sixths—comes not from warmer air but from ocean water eroding ice sheets from below and along their edges. Scientists cite examples like Greenland's Jakobshavn glacier, which is now retreating up to 164 feet daily.

NYC entry-level tech job postings down 49% since 2022, report finds

A Center for an Urban Future analysis of New York City hiring data found postings for entry-level 'computer and mathematical' roles have fallen 49 percent since 2022. The nonprofit's director, Jon Bowles, says the traditional first rung of the tech career ladder is under intense pressure, with similar declines showing up in administrative, financial, media and education entry-level postings.

NOAA confirms 'Super El Niño' status ahead of 2026-27 winter

NOAA announced on September 14 that El Niño has officially crossed the threshold to become a 'very strong event' for the Northern Hemisphere fall and winter of 2026-27, a designation known as a Super El Niño. Forecasters say this could become the strongest El Niño on record, with effects lingering into 2027 and potentially raising sea levels along California's coast by up to a foot.

How to decide if your EV needs a Level 2 home charger

Electric vehicle owners can charge at home either through a standard household outlet or by installing a faster Level 2 charger. The choice depends on factors like battery size, the car's maximum AC charging speed, and daily driving distance, rather than a need to always charge to full like a phone. Home charging remains far cheaper than gasoline, roughly a third of the cost, even before factoring in a Level 2 upgrade.
