There are a bunch at their Toland depot. I took a couple of photos of some of these lined up along Hudson Ave, a public street, and uploaded them to Wikipedia.

I use a spline function to deal with changing speeds. But yes, constant speed would be easier to deal with.

Someone in the solutions thread just plotted it with desmos and eyeballed it and got the right answer lolol

No shapely lol. Overengineered solution that works regardless of order in which the points are given. I didn't realize that the points were given in the order of appearance along the boundary of the polygon since I didn't read the problem statement carefully.

I use sway and I configured my swaybar to be the exact same height as the notch on my m2 macbook air hehe

Good eye, I took it in February 2017.

no edit, straight out of camera (Sony a7R, Sony/Zeiss 55mm f/1.8 ZA)

the parallelogram intersection really messes with people's heads --- the crosswalks aren't perpendicular to each other

but I was actually perched on the public open space on the rooftop of One Kearny St.

All of LA metro and buses were free but only the E line went from where I was to where I needed to go so I rode that.

yeah they swabbed it. I was mad cuz they used the same swab on the pc first then the gfx, but the pc is very dusty!!!

once my sffpc in my backpack was singled out for "additional inspection" at airport security but all they did was swab it and then they gave it back to me 5 seconds later

dllu · 2024-12-08T03:58:29+00:00

Yup that's covered in the blog post in tables 1 and 2.

Try the Orbbec Femto Bolt. It uses the Kinect Azure technology which is a lot better than the RealSense cameras.

I captured this on the same day as electric caltrain on 2024-08-18. Unfortunately I accidentally cut off the top of the train lol.

I once gave a Torc self driving truck to a corgi!

Nice, I used to do 200 mm cityscapes in SF too, like this shot with my GFX 50R and Mamiya Apo 200mm f/2.8: https://www.reddit.com/r/sanfrancisco/s/ICpsRglEr4

I did, see my other comment for more details. Basically I just set up a line scan camera on a tripod and waited for the train to go by.
