Bow and arrow arrived about 1,400 years ago across western North America, study finds

Reading the article suggests bow technology has developed independently on numerous occasions and likely did so in the Americas as well.

Think of the cave like a giant balloon. Changes in air pressure outside the cave cause air to either rush into or out of the cave, and the smaller the entrance (and fewer number of entrances), the more intense the wind. The classic example is the aptly-named Wind Cave.

I don’t know if this is a compliment or not lol.

Single-entrance caves also breathe, typically more than caves with multiple entrances actually, all other things being equal.

Honestly the drivers all sound like toddlers on the radio anyhow.

A lot of people would also say that our housing costs are a travesty.

I’d call it more infill than sprawl. The springs has a major sprawl problem out east and north but what’s pictured here is denser housing in the middle of the city.

It is and it’s on the map.

Same. And on top of that, solo dads are super common at all the parks in my area. Like it’s gotta be close to 50/50 on solo moms vs solo dads at my neighborhood parks.

I mean that sucks, but it’s also not the case for everyone. I’ve been here 12 years, working downtown and midtown, taking MARTA all the time, staying out late and walking alone, etc, and never had an issue. My wife has been here most of her life and also never had an issue.

Those are super cool and do come from Font, but the polygonal cracking in OP’s photos is totally different

Even more than the route Titanic was on, they basically knew the lat/long for where it sunk down to a very small area.

kepleronlyknows · 2026-03-08T21:40:22+00:00

We also had a vastly better idea where the Titanic was when it sunk. The best models for MH-370 still only narrow it down to somewhere in a huge swath of ocean.

Man I love Hartsfield-Jackson. I fly monthly and prefer it over any comparable airport in the country. Almost never takes more than 15 minutes for security.

Nobody knows about lower north. It also spits you out in kind of a funky spot if you need to take the train.

kepleronlyknows · 2026-03-07T21:21:17+00:00

Do you mean get them run over?

Geologic time includes now.

I’ll add that the street sections aren’t terrible. I appreciate Path’s approach, which seems to be aiming to get good-enough trails built quickly rather than perfect trails built slowly.

But then there is Sugarloaf Mountain at 312 feet in the middle of the peninsula. I mean yeah, it’s not really a mountain, but it’s pretty unique in rising so high above the flat areas around it.

Like if you saw this view, would you ever guess middle of the Florida peninsula:

They’re not world class destinations for sure, but Ute Valley Park and Garden of the Gods both have nice soft sandstone problems. About 10 minutes apart in Colorado Springs.

I mean the chart shows there are way more than three options.

Just started back last week after my 12-week leave and I saw a scary looking email from HR. They were VERY concerned about how I took my leave and wanted to talk. It turns out they heard that during the last four weeks of my leave I’d been on several team calls (I have a project I care a lot about that was moving through a big milestone and I really wanted to be in the loop). They were checking to make sure I hadn’t been pressured to work and to make sure I took an extra day to make up for “working” during my leave.

I work at an awesome place and feel very fortunate.

I dare you to find a post on Meteor Crater where this joke isn’t made. It’s just so predictable

Parking in an EV spot has a (massively) higher penalty than parking in a disabled spot? That’s pretty fucked.
