DEXA Scan Deep Dive, With Insights From the Experts (2025)

wired.com Boutayna Chokrane 2025-09-25 06:30:00

Earlier this summer, I found myself lying flat on a padded table in Tucson, Arizona. A mechanical arm hovered above me, scanning my body from head to toe while I tried to remain still. Fifteen-ish minutes later, a clinician handed me a thick packet of results, which included details on bone density, lean muscle mass, body fat percentage, and color-coded visuals showing exactly where each of these metrics was located within my body. This was a DEXA scan, short for dual-energy x-ray absorptiometr

C. Scott Brown / Android Authority TL;DR Samsung has confirmed to Android Authority that the Galaxy S25 FE has an optical-based fingerprint scanner. This comes after unofficial claims that the phone has an ultrasonic scanner. An ultrasonic fingerprint scanner is faster, more accurate, and works with wet fingers. Samsung launched the Galaxy S25 FE last week, and it brings a couple of notable upgrades. We also heard rumors that the phone would have an upgraded in-display fingerprint sensor, bu

9 great PDF scanner apps you should use instead of Microsoft Lens

How often is the query plan optimal?

news.ycombinator.com Unknown 2026-01-28 23:19:27

The basic promise of a query optimizer is that it picks the “optimal” query plan. But there’s a catch - the plan selection relies on cost estimates, calculated from selectivity estimates and cost of basic resources (I/O, CPU, …). So the question is, how often do we actually pick the “fastest” plan? And the truth is we actually make mistakes quite often.
