What good are wearable computers if the data Is wrong?

Published Fri, 21 Feb 2025 21:12:45 GMT

Smartwatches from tech companies like Apple and Garmin make it easy to see a number that could reflect how old you are more accurately than your age: the VO2max, the maximum amount of oxygen that your body can use during intense exercise.The higher your VO2max, exercise experts say, the better your cardiovascular fitness and, potentially, the longer your life. In the past, only serious athletes sought a traditional VO2max test, which involved wearing cumbersome sensors while exercising inside a lab, but now anyone can get an estimate by wearing a smartwatch and moving around.Is it good to have access to this kind of information? And how accurate could a wearable be? In the last five months, when I fell down a VO2max rabbit hole, I learned some uncomfortable truths about my health and the limits of smartwatches.First, let me tell you about my fitness journey. In November, while I was out celebrating my birthday, my Apple Watch delivered the most unwanted gift: a notification of a hig...

Bill to provide $17,000 for those opting out of public schools defeated in California senate committee

Published Fri, 21 Feb 2025 21:12:45 GMT

The latest push for education savings accounts – a type of school choice voucher that would give parents money to finance their children’s non-public schooling – was defeated in a 5-2 vote in California’s senate education committee earlier this week.If passed, Senate Bill 292 would have established a fund for students who opt out of attending public schools that is equivalent to the amount the state spends on each student every year — around $17,000 per pupil during the 2022-23 academic year. Families could have used the money for private school tuition or other educational expenses. Leftover funds could be put toward higher education costs once the student graduates from high school.“California’s government run schools are failing too many students,” said the bill’s author, Senator Shannon Grove (R-Bakersfield) in an emailed statement. “The government focuses more on funding institutions than students, and most parents have no other options.”Similar education savings ac...

49ers’ last-pick Purdy magic has inspired NFL to dig in on this year’s late-round QBs

Published Fri, 21 Feb 2025 21:12:45 GMT

SANTA CLARA — One year ago, Brock Purdy’s phone rang, he retreated into his parents’ bedroom to take the call, then faked out his family by pretending it was just another team looking to sign him if he went undrafted.It was the 49ers calling. They would select him with the 262nd and final pick in the NFL Draft. Nine months later, Purdy directed them to eight straight wins, before his elbow got hurt and they lost the NFC Championship Game in Philadelphia.Purdy’s stunning breakout has a carryover effect on this coming NFL Draft.The 49ers are enamored with Purdy, and they envision him as their long-term starter, as long as his surgically repaired elbow recovers by fall, as expected. (That arm showed nice range of motion Friday night as he acknowledged fans who gave him a standing ovation while attending the San Francisco Giants’ game, seated near home plate with a few 49ers offensive linemen.)Nice to see you, Brock #BayAreaUnite pic.twitter.com/2FDiwHMpw3— SFGiants (@SFGia...

Prep baseball: Bold decision pays off for James Logan – ‘We needed to try something’

Published Fri, 21 Feb 2025 21:12:45 GMT

UNION CITY – With the game between James Logan and Washington-Fremont tied during the top of the fifth inning, first place in the Mission Valley Athletic League was still up for grabs. That’s when James Logan’s Aeryk Hernandez made as gutsy a call as a coach could make with two outs and sophomore Jordan Medina on third. “I felt like we needed to try something, so I just said ‘Let’s put this straight steal on and hope that something happens,’” Hernandez said.“I read the signs and I was in complete shock,” Medina recalled thinking before he sprinted home.   “I was wondering, ‘Am I really about to do this?’” Washington’s catcher initially appeared to tag the runner out, but the home plate umpire deemed him to be blocking the plate. That gave James Logan a lead in what would eventually become a 5-2 victory. UNION CITY – James Logan players Jesus Vasquez (3) and Jordan Medina (16) celebrate after the final out. James Logan and Washington-Fremont played...

Mathews: Newsom’s “Campaign for Democracy” should start in California

Published Fri, 21 Feb 2025 21:12:45 GMT

Gov. Gavin Newsom is doing a good thing by launching “Campaign for Democracy” against authoritarian governors who are limiting freedom in Republican states like Alabama and Florida.But what he’s campaigning for is not democracy.If democracy were his mission, he’d be campaigning in California — because our state has a deficit of it.Newsom’s “Campaign for Democracy” — the name he’s given to a series of events in Republican states and to the political action committee paying for them — isn’t just a misnomer. It’s part of an epidemic of leaders who portray whatever they are doing as “democracy,” and their political opponents as a threat to it.To understand the problem, let’s start with a definition: Democracy is everyday people governing themselves.But Newsom’s campaign has little to do with getting together with your neighbors to practice self-government. The governor instead is leading a large national media campaign to confront sins of politicians with whom he disagrees.On the Campai...

Customers shred electricity bill plans backed by PG&E, other utilities

Published Fri, 21 Feb 2025 21:12:45 GMT

OAKLAND — A prominent Bay Area energy economist is warning that forthcoming changes to the way PG&E and other power companies in California bill customers could leave many people with sticker shock.The plan, enabled by state legislation and revealed recently by PG&E, Southern California Edison and San Diego Gas & Electric, envisions the addition of a monthly charge for all residential customers that receive electricity services from one of the three power utilities along with ongoing charges based on how much electricity people use each month.Ahmad Faruqui, an economist who has consulted with all three of the utilities involved in the revamp and who has testified in proceedings before the California Public Utilities Commission (CPUC), which oversees them, doesn’t like the idea of grafting on a new fixed income-linked fee to the existing system of electricity charges.“Right now, monthly bills are totally based on energy consumption and user behavior,R...
