Obviously, of course, a client would never _cheat_ or lie about an event. No, no, no. We can totally trust them.

You could try a hypertree

but that's usually for acyclic data.

I find the killer feature to be the ability to pause games. Sure, I could do that on my PC, but since this whole Deck is dedicated to just running the game, and I can set it aside, do the thing I need to do (maybe on my PC) and come back and start right where I left off, it feels different, more integrated, because for a little while, the game state and the deck state are the same. It is less like the Deck is running the game and more like the Deck is the embodiment of the game.

There's always Wrigley's that went from offering gum as an incentive to buy soap to just selling the gum... "Make something people want"
> In 1891, 29-year-old William Wrigley Jr. (1861–1932) came to Chicago from Philadelphia with $32 and the idea to start a business selling Wrigley's Scouring Soap.[14] Wrigley offered premiums as an incentive to buy his soap, such as baking powder. Later in his career, he switched to the baking powder business, in which he began offering two packages of chewing gum for each purchase of a can of baking powder. The popular premium, chewing gum, began to seem more promising, prompting another switch in product focus. Wrigley also became the majority owner of the Chicago Cubs in 1921.

I'm tempted but I think I'll pass.
Recently my son was enthusiastic about anaglyph images viewed with red-cyan glasses. These are much better than what they had when I was a kid because the cyan filter passes both the green and blue channels. You can use whatever color you like as long as it isn't red or cyan.
I got enthusiastic too.
We found out that you can't (in general) make a good anaglyph image with a 2-d image and a height map because the left eye and the right eye can see around objects so the 2-d image usually is missing pixels that the left and right eye would see.
You could reproject an anime image if you had the cels; you could reproject the image for the left and right eyes by simulating the multiplane camera.
I am just starting to take 3-d photographs by moving my camera and that way I get all the pixels for the left and right eye. That lens might be better for taking portraits at very close range but I don't know if it would beat my current lenses. Certainly I could get a really good telephoto lens for that price today whereas I don't even know if I'll be taking 3-d photos a year from now when that lens would arrive.
I'm a big fan of Loreo stereo lenses. They're well made and inexpensive.
You can use stereo pairs to calculate depth, and in this case, you only lose half your horizontal resolution (vs. losing significant horizontal and vertical resolution on the K lens)

I don't understand how refilling for $0.86 per wash is better than the $0.67 per wash if you use their cartridges? Or how that becomes "75 times cheaper".
https://github.com/dekuNukem/bob_cassette_rewinder#cost-show...
How does this math make any sense?
With that, the total cost per wash is:
0.62p + 0.018p = 0.638p, or 0.87 US cent!
We know from earlier that Bob Cassettes costs 48p (67c) per wash.
Therefore, refilling it yourself is more than 75 times cheaper, resulting in a massive 98.7% cost saving compared to buying new!
ARothfusz commented on Launch HN: Art in Res (YC W20) – Buy art directly from artists · Posted by u/JohnFriel
I really enjoyed making combinations on the filters to see what (I thought) unlikely combinations existed, and I was happy with what I found (e.g. minimal organic, architecture face). Does the artist apply the labels? Or is classification part of your curation? In any case, nice work. I hope your market finds you!

These IoT stacks like AWS greengrass (yes the marketing department smoked that day) or Azure IoT hub are missing something fundamental in my opinion : device management.
It would be nice if they could do stuff such as updating the Linux distribution.
What about https://aws.amazon.com/iot-device-management/ ?
Almost 50 years old now, and still sending data.
What would I change about software development now to program like they did 50 years ago? I would program like they programmed 50 years ago: assume it has to work. Assume updates will be risky and expensive. Build in failsafes and watchdogs and redundancy. Be able to replicate the build every year for 50 years. Train people to know what the logs really mean, every year for 50 years. And launch it before the bike shedding can begin!
