Doesn't the device need satellite connectivity?


At the same time our government wants to increase the cost of public transportation [1] with the age old argument that it is too expensive compared to the cost of individual transportation.

While I don't have the numbers to analyze the costs it just doesn't make sense to me that a car with a single driver can be more cost effective than a bus, tram or train I guess the automobile lobby has convinced loads of my colleagues that individual transportation is price-comparable to public transport, even in Switzerland...

This is a fascinating area to research. Of course there are trade-offs to model including a few such as: price of person's time waiting for next bus, time to go all around the mulberry bush instead of point to point, and hassles and personal safety in public places.


In my local sunglass store iI can buy genuine Wayfarers for a bit more than 100$ so I guess Luxotica’s margin is even higher than expected…


Luxottica cannibalized and cheapened Ray-Bans a long time ago; see my comment above.


You can definitely go to a mall and get ray bans with solid barrel hinges


You can't. They were only available on the original Ray-Bans before they sold out to Luxottica.



Thanks! I wasn't aware of that model; they must be new. Looks like they were introduced back in March of this year. Good to see the barrel hinges. But a couple of questions:

Are the lenses glass? (It says they're G-15, which is supposed to be mineral glass, but I don't know if RB has changed the definition somewhere along the line and replaced them with plastic).

Are these only available in EU, or in the US as well?


G-15 is just the tint color (the gray/green). It’s not the material. I’m pretty sure that only way you’re getting glass lenses from Ray-Ban is if you get the high index prescription lenses.


They sell them for like 20 times what they cost to make, according to https://seekingalpha.com/article/4472420-essilorluxotticas-m...


I was skeptical about your claim but I turns out that you are right! I knew about agricultural biogas production but never though about the potential of methane production from waste water treatment.

Even more surprising is that the generated biogas is used in the municipital gas supply in my town[1]. So I literally cook with fecal products.

You eat what you ate!


We actually do this as the basins populated with bacteria that process our waste are heated to improve their metabolic activity and speed up the process.

edit: in regular waste processing plants


Problems arise as soon as you (ab)use a metaphor (used to explain a higher level/adjacent problem) to explain concepts it was never meant to model.

Example: Array of items as a shopping cart: how do you efficiently remove an item from the array (as you can from a shopping cart)?


There's always a possibility that a bad metaphor can be made, but this doesn't mean that metaphors themselves are bad. They require at least some consideration in order to communicate and relate the relevant details of something to another thing. It would be like criticizing multiplication because sometimes people forget to carry extra values


Did you miss that the child stuff is explicitly mentioned as negative prompt (which I assume is used to let the network know that you don't want those traits in the output image)?


I didn't know what a negative prompt is.

I've used my ignorance as an opportunity for others to better interpret this also.


I think you mean the median.


What I got from similar subreddits (e.g. /r/bestoflegaladvice) is that you'll get (shaddow)banned really fast if you click a link in the subreddit and coment on the linked post.

Just mentioning this because I agree with the point you make (in general).


I think OP didn't mean that you can absorb fentanyl through the skin but rather that you'd have trace amounts of fentanyl (or even the more powerful analogues such as carfentanyl) on your hands and then touch your mouth or eyes. That can certainly kill you.
