I wonder what the deal is with this little airplane. This isn't near the Super Bowl.

I'm a West Coaster and I take the train daily. And I lose AT&T connectivity every ride right here. If you know the area, you know why.

Anyone know what the @caltrain.com equivalent of this slide is?

This seems unfair to Port Wash line commuters

If more cars were like that Smart car, more cars could park on the street

When I first moved into my house here, it was all single pane windows. Some windows couldn't even be fully closed because they were shutter-style windows. As someone from a place where it snows, this was all quite surprising.

Also, I think there's some self-selection bias for a thread like this.

Did they make those aprons out of kevlar or something? How did they last so long.

Reminds me of this photo of took in Dec 2019 of a guy offering rides at JFK, in front of a sign warning passengers about this.

TIL Westfield ran both. The wayfinding (or lack thereof) makes it feel like the management of both are at war with each other

Maybe someone could get the rights to open a J&R Music World at the Fulton Center. Then... it could be twice as dead?

I remember as a kid, that was the kind of snow that people die from heart attacks from shoveling. So my dad would make me shovel it 🤔

I broke a woodenshovel handle once doing that.

If you’re not a fan of getting stuck in traffic on 101, then you should support this or more people will be on 101 rather than Caltrain

Hey @caltrain.com - are you folks aware that the clipper tags get stuck in pending for days?

I've heard from a professor in one of my group chats that blue book / in-class essay exams are back, thanks to GenAI. So maybe writing long pieces of text by hand is a thing again?

This part is so stomach churning. It seems to me that Airbus planes should have a mechanism to keep both side-sticks' physical position linked, much like the yokes on Boeing planes.

Back in the day, the school store sold a t-shirt that said "It's Johnssssss Hopkins"

"Concluding Commentary: What occurred for the enrollment in and immediately after the worst years of the pandemic had no precedent, and thus no prior data trends to look back on, from my 40 years of experience in this enrollment forecasting business."

Wow.

I was reading through a report that a demographics consultant prepared to forecast enrollment in my school district, and this historical chart caught my eye. I wonder what accounted for the rocket ship growth Obama era.

I have a few pending transactions.

The funny part is the 27 minutes ago one was at 830am.

@adtechgod.com See you at Marketecture Live in March! Super excited. I've heard such great things about the previous ones!

This is fascinating. It turns out Canada, and different US states use different elevator codes - while the rest of the world uses the same single elevator code.

As a result, elevator maintenance is 10x more expensive than rest of the world due to lack of competition.

I'm assuming the building on the right is the current PABT? Are they going to eminent domain the block to the west to fully build the other building?

So if I show up at 7:30am and ask for early check-in, I won’t get charged a fee? How odd.

@caltrain.com I’m not sure what’s going up with the Clipper 2.0 roll out, but this doesn’t seem like it’s working well.
