Building a web search engine from scratch in two months with 3 billion neural embeddings A while back, I decided to undertake a project to challenge myself: build a web search engine from scratch. Aside from the fun deep dive opportunity, there were two motivators: Search engines seemed to be getting worse, with more SEO spam and less relevant quality content. Transformer-based text embedding models were taking off and showing amazing natural comprehension of language. A simple question I ha

Google started testing it in June and it should be available in the coming days to English language users in the US and India. Preferred Sources seems pretty simple to use.

Megan Ellis / Android Authority A few months ago, I switched from Google to Brave on my Android phone. While I initially did this to force dark mode on my mobile browser and remove ads, I discovered plenty of benefits to using Brave over Chrome. One of these is access to Brave’s search engine, which prioritizes higher quality results with fewer ads and sponsored results compared to Google Search.

This quantum radar could image buried objects

technologyreview.com Sophia Chen 2025-12-02 08:00:00

The glass cell that serves as the radar’s quantum component is full of cesium atoms kept at room temperature. The researchers use lasers to get each individual cesium atom to swell to nearly the size of a bacterium, about 10,000 times bigger than the usual size. Atoms in this bloated condition are called Rydberg atoms. When incoming radio waves hit Rydberg atoms, they disturb the distribution of electrons around their nuclei. Researchers can detect the disturbance by shining lasers on the atoms

People returned to live in Pompeii's ruins, archaeologists say New evidence suggests people returned to live among the ruins of Pompeii after the ancient Roman city was devastated by a volcanic eruption. Archaeologists believe some survivors who could not afford to start a new life elsewhere returned to the site and may have been joined by others looking for a place to settle. Pompeii was home to more than 20,000 people before Mount Vesuvius erupted in AD79, burying - and preserving - much of
