I spent a week at NeXT headquarters in December 1996 for training. I might have been the last person trained on NeXT computers. About a week later, NeXT was sold to Apple. I wrote about it in 2011 when Steve Jobs passed away: ken.arneson.name/2011/10/my-s...

I'm old enough to remember black and white TVs, and these Bay FC kits feel like when TV shows actually used to advertise, hey watch our show, we're in now in color

Well, sure, Bay FC just lost last year's team assists leader to an ACL tear, might as well balance that out by getting rid of last year's leading goal scorer, too, or something

Looking back at you, Wendy

Sure the US may have won the hockey gold medal, but William Shatner sang Rocket Man at me last night, so isn't Canada the ultimate winner?

This month, people: I passed two kidney stones. Then I turned 60. Then my work got shown on the Super Bowl. Then my work got shown on the Pebble Beach Pro-Am broadcast. This morning, I told Walter Koenig where the nuclear wessels are. And THEN I witnessed LIVE William Shatner sing Rocket Man

World Cup soccer, Olympic curling, Olympic hockey, it’s all good

If I got rich, I'd dedicate my life to solving the 2,000 year old problem of passing camels through the eyes of needles. It's a geometric folding problem too complex for humans, but with wealth we could build the AI Quantum Supercomputers needed to solve the camel-needle problem once and for all.

I, for one, welcome our new Australian overlords to Alameda

<Fred McGriff voice> As a dual US-Sweden citizen, today’s cross-country skiing results have my full endorsement.

As a dual US-Sweden citizen, whenever both your teams are playing each other, all you ask is that, whoever wins, it comes down to the last shot.

As a dual US-Sweden citizen, today’s curling results have my full endorsement.

Update: we got an in-game graphic, too.

Super Bowl pregame just showed some graphics using @weatherapplied.com data, so at least all that work wasn't for nothing!

After watching the Sweden-Germany hockey match earlier, this USA-Czechia hockey match looks like it's being shown at 1.5x playback speed.

Ten years ago, for my 50th birthday, the city of San Francisco honored me by placing giant "50" signs all over the city. I hear that SF has done a similar thing this year for my 60th birthday, albeit with roman numerals, but sadly, I am unable to attend due to my kidney stone issue. But thanks, SF!

One of my kids ran cross country and track, and tore an ACL at the end of junior year of high school. Surgery then would have meant the bummer of missing most of senior year sports, so they delayed it until after senior year was over. Couldn't run as fast without an ACL, but gotta admire the effort.

The thing I just reposted that said "how atmospheric conditions can move a baseball up to 30 feet" -- that's a bit low. It's more like "up to 110 feet", mostly on very high popups on very windy days at short ballparks like Wrigley or Fenway. 30 feet gets bested by 100-200 fly balls/popups a year.

Weather Applied Metrics has been working with Major League Baseball for six or seven years, modeling every stadium to show how atmospheric conditions can move a baseball up to 30 feet, and now NBC is preparing to showcase the technology during the Super Bowl

The good news is that my bronchitis finally went away. The bad news is I got rid of it by spending yesterday in the ER being pumped full of drugs for kidney stones, and I guess those drugs cleared my bronchitis. But if you have a choice between bronchitis and kidney stones, choose bronchitis.

Watching Brighton/Everton and one of the advertisements flashing up on the sideline video board at the Amex Stadium is suggesting folks "Experience Kissimmee, Florida," which seems less like an invitation and more like a warning.

Here's an article from Front Office Sports about NBC preparing to use @weatherapplied.com data at the Super Bowl, should there be any sort of impactful weather at all. frontofficesports.com/nbc-has-a-fa...

It's so cold in Chicago that I'm using which direction the players' breath blows as it comes out of their mouth to verify that the @weatherapplied.com model for Soldier Field is accurate at the 6 foot level.

The forecast for the 49ers-Seahawks game on Saturday is for so little wind that they if they played it across the street at T-Mobile Park with the roof closed, it wouldn’t change the wind impact at all.

Not sure how I'm supposed to feel about that Korean car commercial they just showed in the Chargers-Patriots game advertising that it can protect you against evil Swedish furniture ("Svenska Möbler") trucks.

Philly weather: Sustained winds of 15 to 20 mph with gusts up to 35 mph will put wind chill temperatures in the 20s for the #49ers game against the #Eagles this afternoon.

Looking at that JAX missed FG, and the GB ones last night, the extent to which spin axis/ball tilt causes missed kicks is underrated. It might be the biggest cause of misses. Blame often goes to the kicker or to the wind, but a big piece of the ball spin axis is whether the hold is straight or not.

Unusual missed FG by Green Bay before the half because of wind and a leftward ball tilt/spin axis. * With no wind and a neutral spin, it has distance, but misses wide right * With actual spin and no wind, it's not wide, but misses short * With actual spin/wind, it has distance, but misses left.

A 55-yard FG could see ~5 feet of lateral movement. #PlayTheWind #WeatherApplied #Packers #Bears Wind at uprights height (photos 1&2) Wind at north end zone (photo 3)

Packers @ Bears — Wild Card Forecast: W winds 10–20 mph. Gusts up to 28mph. Classic barrier effect at Soldier Field. Near field level, kicks drift opposite of the prevailing wind. 🏈 FG to north end zone: pushed left (slight tailwind) 🏈 FG to south end zone: pushed right (slight headwind)

This story pulls back the curtain that we at @weatherapplied.com have been doing some work to prepare for the Super Bowl. www.sportsvideo.org/2026/01/08/l...

I live at *111* Fake St and there's a dentist office at *1111* Fake St. About once a year, someone arrives at our house expecting us to give them dental care. Equally frequently, we receive packages full of dental gear.

Re: the Phamgraphs article, in which I'm mentioned, and this sentence: "If WAM can measure this for homers, perhaps they can measure it for outfield fly balls, as well." @weatherapplied.com does measure the wind impact of every fly ball. Also, for every pitch. www.nytimes.com/athletic/694...

Name drop alert: I get mentioned 8 minutes into this podcast in a segment discussing the A's.

Happy Gingko Leaf Dump Day to all who celebrate!

Windy day in Seattle for Rams @ Seahawks. Our @weatherapplied.com model predicts a much bigger impact in the north side of the field. The south side has both vertical and horizontal eddies that result in dead spots, like the calm in the eye of a hurricane. Strongest winds in the north side end zone.

Having Oski featured on the British Cracking the Cryptic sudoku channel meant I was compelled to solve this puzzle, and I did, eventually, but it was rather difficult. But hey, if you want easy problems to solve, don't go to UC Berkeley. www.youtube.com/watch?v=KoMF...

Not much fun getting sick on the third day of the Winter Meetings and having to spend an extra two days in a Florida hotel room nursing myself, but my consolation prize is that I spotted a roseate spoonbill in the wild this morning. #iykyk

This is burying the lede, which is that I walk by in the background at 32:54 of this YouTube video.

Achievement unlocked! Nice to see @jayjaffe.bsky.social and meet his colleagues @fangraphs.com including the unrelated @keatonarneson.fangraphs.com!

I have now seen Bruce Bochy and Scott Boras, I just need to find @jayjaffe.bsky.social to complete my fourth Winter Meetings trifecta.

First time in a Waffle House. There are so many food franchises that Bay Area folks just don’t have access to.

Hello Orlando. hmu if you’re here, I’d love to say hi.

I haven't seen yet which World Cup team is practicing at the Oakland Roots/Oakland Soul training facility in Alameda, but Paraguay and Jordan each have two games at Levi's Stadium, so it would make sense that it would be one of those two.

Between Tosh Lupoi at Cal, Ron Washington being named IF coach with the Giants, and Emma Coates going to Bay FC, I want to wish everyone in the Bay Area a Happy New Coach Day!

I have these sheets of 1970s RC Cola cans depicting Joe Morgan and Lou Brock that were never actually made into cans. I have no recollection of how I ended up with these. Someone gifted them to me at some point? The cans are worth $8 on eBay, I wonder what the uncanned sheet is worth?

Understanding how wind impacts sports starts with understanding wind itself. The new WAM blog breaks down the basics: • what drives wind • how we measure it • why it changes across space and time blog.weatherapplied.... #weatherapplied #playthewind
