Human binocular depth perception only works at distances of less than 30 feet, which is not very important for most driving. Everything beyond that is from other cues such as motion parallax, relative size, lighting and shading, and perspective.

The reason people become clumsy when using night vision devices is because they have a tiny field of view that only moves when your head moves. You can close one eye and walk around just fine. But if you attach two toilet paper tubes to your face, you'll have trouble balancing and avoiding obstacles. The clumsiness is caused by the lack of peripheral vision and the inability to quickly glance (since the only way to change what you see is to turn your head).


Those cameras are fixed whereas eyeballs have multiple degrees of movement via the eye socket and skull mounting apparatus allowing very sensitive parallax measurements. It's really not the same at all.

This is a common misperception. You cannot estimate the shape of simple things in low light. Even humans are susceptible to optical illusions and are effectively blind during certain times of day (try driving in the direction of the sun during sun rise/set). Lidar is not susceptible to any of these things. Similarly ML will never solve low light or direct light situations, that is a physical limitation of cameras.

I really liked this version "Oblique Strategies: Prompts for Programmers" especially for when you're stuck on something.

Years ago for my sister's 30th birthday, I did a fun project involving the USPS.

I wanted to send her the message "Happy Belated Thirtieth Birthday!", which is 30 characters, via postcards, one character per postcard.

I found 30 post offices in unique places throughout the U.S. (For example, I found a town that had the same name as her given name in Illinois. I found another with my name, etc.)

I used Zazzle to print a custom post card for each location with a picture of the location on one side, and a large block letter on the other. I just did a Google image search at the time to find photos of the location. Here's the image I used for "Truth or Consequences, NM":

I then hand wrote a message on each postcard that started with the block letter. This was because she'd be receiving the postcards one-by-one and I didn't want her to realize right away that a message was being spelled out. It would seem like a postcard I might send her from that location if I'd actually been there.

I also found a set of 50-state stamps the USPS had previously issued on eBay, and used the correct state's stamp for its postcard.

Finally, I round-tripped each postcard through its respective post office by mailing it inside an envelope addressed to the postmaster at that post office along with a note to the post master:

Dear Postmaster:

I am mailing my sister 30 postcards from 30 towns for her 30th birthday. I have enclosed a postcard, which I ask be hand-cancelled with a postmark from your town. To protect the postcard from machine cancels in its journey through the mail system, I have enclosed a stamped envelope addressed to my sister in which to seal and mail the postcard. Thank you very much for your time!

I wasn't sure if this would work, but damn if she didn't get all 30 postcards each properly postmarked.

I dropped them all in the mail in NC. Some went as far as Alaska and Hawaii.

She received them in Miami. I think she got the first one within a few days and the rest dribbled in over the next two weeks.

Edit: here they are after she received them all:

Civ 4 was the greatest Civ. Civ 5 and beyond tried to turn it into some kind of board game.

"Death stacks" happen in real life. e.g.: every human battle ever, including Normandy in WW2, I don't know why Civ 5 chose to remove them.

Civ 5 and 6 have nice features but it's no longer Civ to me. Plus, the excessive amount of $60 DLCs are a no-no.


Sometimes you don't want to blindly trust dhcp. My isp is set up so that the internet-facing host gets an IP through dhcp. I don't want to use the ISP's dns however.

I use OpenBSD on that machine. I think it was "ignore domain-name-servers" in dhclient.conf that fixed that for me.
