Someone on twitter had the idea that he could use the camera to take a picture of the character (or his whole password) and copy/paste it using the built-in ocr feature.

I don't have a text password on my iphone so I don't know whether you can paste into that field.

In a cold climate it's essential to have air/insulation between the floor and ground.

I wonder if you could partially get around this by using the "ghost kitchen" model. Offer food only for delivery, but then "hire" customers to deliver their own meals if they want it cheap.

Curious how you set it up. Do you have to manually update it when inflation data comes out, or is it automatic?

Seems like YT is mostly focusing on the interaction between streamer and audience (which makes sense because streaming is big with young ppl rn).

I understand "ambient streams" to be more like a setting for a group chat or chat room, where you're interacting with friends or strangers only, there's no focus on a single creator/streamer. Like hanging out at an interesting location instead of a featureless room.

I think you're right that contributed, but at least the federal EV subsidy was trying to mitigate that effect by also subsidizing used EV purchases. I just bought a used PHEV and got a subsidy right before the cutoff. So the effect might get worse now that the program has ended, though I suppose new EV prices should come down too.

I do wonder if early world explorers had been from the southern hemisphere and a tradition of "south up" was already established, if it would still look better to us to have more land on top.

Also if the map is flat on a table, more stuff is closer to you.

Careful, though. There isn't a constant "pi" for all metric spaces. Using distance along the surface of a sphere, the ratio of a circle's diameter to circumference depends on the size of the circle.

With tetration you're not dealing with orders of magnitude anymore, but orders of magnitude of orders of magnitude.

Fun post! I drew the first 5 iterations by hand myself and I'm finding it easiest to think of as a self-similar coloring of a square tesselation.

If you start with the shape of iteration 3, it tessellates as a 5x5 square tile. Make an infinite grid of those tile shapes with one iteration 3 version in the center. Treat that center tile as the center square in the iteration 3 pattern and color the tiles around it according to how the 2nd and 3rd iterations were built of squares. This gives you the 4th and 5th iteration and you can continue to iterate on the coloring outwards to color the grid of tiles in the wallflower pattern.

As someone who doesn't develop in python but occasionally tries to run python projects, it's pretty annoying to have to look up how to use venv every time.

I finally added two scripts to my path for `python` and `pip` that automatically create and activate a virtual env at `./.venv` if there isn't one active already. It would be nice if something like that was just built into pip so there could be a single command to run like Ruby has now with Bundler.

New comment by mckeed in "Every UUID Dot Com"

mckeed — Sat, 07 Dec 2024 01:38:27 +0000

Would it be easier if only the lowest bits of the index contributed to the "entropy"? Like if the 2^16th UUID was the one right after the first and n + 2^16 was the one after the nth. You wouldn't notice the pattern but it'd be easier for the computer to handle. I guess if you were searching for a substring you might notice the ones surrounding the matches look almost the same from match to match...

Maybe "unleashed" to connote a potentially dangerous power is loose.

The goal is the same as Tetris – to last as long as possible before overflowing. This just doesn't have the mechanic of gradually getting faster.

I kept being surprised seeing air-breathers deeper and deeper. I had no idea narwhals dove down to the depths where things live on hydro-thermal vents. Also that penguins have been near twice as deep as scuba divers.

I thought I was using GPT-4, but it appears that's only available to paying customers so far? The question I was getting repeated wrong answers to was "Can you make up a palindrome that starts with 'Dude'?" If you want to try that with GPT-4 I'd be interested to see if it can do it now or at least knows to say "I can't".

When you correct it, it always seems to say "You are absolutely right! I apologize for the mistake," and then it gives another wrong answer with the same fully confident tone.
