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:

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

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

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.

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.

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.

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.

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.

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)

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.

Tommy Pham makes his case for MLB’s next big metric: He calls it PhamGraphs
Pham proposes a statistical system that would account for how often a hitter faces high-leverage relievers and how defenders cope with wind.

Windy day in Seattle for Rams @ Seahawks. Our

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.

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?
