Look for PA+++ ratings. You might have to buy sunscreen made outside the US, such as sunscreens made in Korea.

You'll be glad to know that BCD is now officially 24 hours, no knocking required.

Looking at it another way: Q1 GDP contracted by 1.6%, Q2 by 0.9%. If Q3 contracts by 0.2%, should we call it a recession?

Many good points, but I'd like to nitpick a bit:

> Singapore has way better clubs than SF or LA. If you want to party hard until late at night it's got plenty of options. Vs SF/LA where there's a 2am curfew your options effectively end at 1:30am.

> Try getting food in LA/SF after 11. Your options becoming Dennys and that's about it.

In LA, go to K-Town (Korea Town). Many good restaurants, lounges, and karaoke places stay open all night long. The party doesn't stop at 2AM.

What if the deer is also color-blind? What colors do deer see anyway?

This makes me think of the camo scenes in RDJ's Sherlock Holmes movie: https://tenor.com/view/sherlock-holmes-robert-downey-jr-chai...

> I've started describing certain types of traumatic events as 'origin stories' for heroes or villains

This reminds me of a certain segment from "This American Life".

Tragedy Minus Time Equals Happily Ever After

Ron Mallett was ten years old when his father died unexpectedly of a heart attack. A year later, after picking up a comic book based on H.G. Wells' book The Time Machine, Ron concocted perhaps the world's most complicated plan to try to see his dad again. A half-century later, Dr. Ronald Mallett wrote a book about his plan, called "Time Traveler".

From the blurb on "Time Traveler": This is the dramatic and inspirational first-person story of theoretical physicist, Dr. Ronald Mallett, who recently discovered the basic equations for a working time machine that he believes can be used as a transport vehicle to the past.

> How is Apple able to stay relevant among younger people and convince them to buy iPhones when Android phones are just as capable and look just as good?

There is quite an element of peer pressure for young people to display status through having new and expensive technology (which I believe is one strong reason the design of smartphones are rev'd every year, so that people can tell at a glance whether you have the latest device), and add upon it Apple's cultural cachet to be the "cool/in" brand, it's often hard for young people to resist the pressure. This has led to issues such as "blue bubble versus green bubble" where young people on Apple devices exclude those on Android device based on not wanting to see an out-of-place color in their text message window.

Xiaomi, which started as a smartphone OEM, has released several e-bikes, which as a non-biker I wasn't interested in, but I though there was a sentiment that it's a pretty good e-bike, especially for its price range. Maybe someone more knowledgeable can chime in.

I felt the same way with the Samsung watch. v1/v2 was pretty meh, but they kept at it, iterating year after year, until I finally pulled the trigger on one because it had the functionality and design that I was looking for. I was specifically keeping away from squarish smartwatches because I didn't want a watch that screamed "smartwatch" and wanted a rounded design, which I find more aesthetically pleasing.

I'm sure I'll recognize the name of the books once you mention it, but could you clarify who the beardy German bloke is and what books he wrote?

Does that concept have a name now? That reminds me of this Japanese comedy sketch about doors: https://youtu.be/nq-2USGVoEE

Tangentially, this is one benefit of wired headphones versus wireless, no software required.

But just to be clear, although I have no experience with the product in question, I do know that some professional speakers used as monitors are active speakers, and they have built-in DSPs to give a flatter frequency curve. Of course there are ones which are not updatable, but then of course you are giving up the ability to apply any bug fixes in the firmware.

To me that statement is saying that one should first establish power, then achieve prosperity, then one would have time for leisure. This is true on a national level as well as a family level.

It's not clear from the webpage, but does it do something different from a paper airplane with just 1 hoop like this? https://www.jpl.nasa.gov/edu/teach/activity/ring-wing-glider...

Good question :)

Yes, all students took the test together on paper and pencil in the classroom; a digital version of the test was not available.

I just went through my files to check, and indeed the final exam for my artificial intelligence class was in-class, 2 hours, pen only (no pencil).

Maybe coming from the chip design world, this is a bit more commonplace and normal-seeming for me. I'm used to huge software packages which cost 5 to 6 figures to license, and additional features which are enabled and disabled based on a license file. No live content (aside from bug fixes). A new version with upgraded features would be another license. I've been out of chip design for a while, so things might be different now.

This might shock and amaze you, but I took many midterms and finals for my CS and EE classes using pencil and paper in the 21st century, and this was at a well-known Californian private university.

I used contact lenses for many years, starting with RGPs when I was in high school and later switching to soft lenses. However, as I and my eyes have gotten old, I've found that wearing contacts for more than a few hours leads to eye pain, and switching to different brands or contacts with higher water content didn't really make a difference. So nowadays it's glasses-only for me.

I think the assumption in the case you are presenting is that efficiency is viewed from the POV of the use of resources aggregated over the whole society. There are other POVs, such as it being more cost or production speed or resource or factory floor space efficient for BMW or their suppliers to maintain one product line as opposed to two, or it being more cost efficient for owners to have the option to turn on the feature temporarily or permanently as opposed to having to have the feature installed afterwards (which may depend on the percentage of owners who turn on the feature).

I think an analogy could be a software package which have some subscription features. The features are already contained in the software, but paying for the subscription would turn it on, and stopping the subscription would turn it off. Regardless of whether you are subscribed or not, it's taking up storage space, although I suppose the low cost of storage makes a difference in degree (but not in kind).

I would read this.

"Apple is moving some of the personal data of Chinese customers to a data center in Guiyang that is owned and operated by the Chinese government. State employees physically manage the facility and servers and have direct access to the data stored there; Apple has already abandoned encryption in China due to state limitations that render it ineffective."

Out of curiosity, what knowledge about electricity and chemistry did you have that prevented the mistakes?

Do you mean in general? There are two reasons given in this thread: medical research and pet (snake) food.

I expect I don't need to explain why it's best to kill the mice humanely for medical research which involve dissection of some sort.

For snake food, it's best to feed mice that have been euthanized. Feeding live mice is cruel to the mice, who experience terror right before death, and there is also the possibility that a struggling mice could injure the snake.

Thank you! Now not being able to think of this word doesn't have to bug me for the rest of the day...

Although technically it is gliding, but to me wingsuits look close enough to flying that adding the mechanism for flapping doesn't really increase the experience of flying by much. (Spoken from a point of view of a spectator and not someone who has done some form of flight besides in airliners.)

I hate to use this phrase, but I think this is what the kids are calling "dripping with privilege" these days.

I always thought effects such as environmental chemical pollution (estrogen analogs), overreliance on nighttime lighting / artificial temperature regulation and dietary issues leading to obesity (both previous items reducing fertility), and increasing cost of raising children (leading to higher investment in fewer children) are some of the main factors leading to decreases in birth rate in developed nations.

> Consider that surviving severe overpopulation is trauma

Recently there was an article posted on HN about how trauma experienced by parents are passed down to children through (a term that means it's related to activation of genes, I believe, but not DNA itself... I thought it was metagenomics but upon looking at the definition I don't think that's it). Perhaps the trauma of overpopulation activated or deactivated some genes which in turn reduced reproduction rate in offspring.

It sounds like they had put some thought into which methods cause the least suffering. It doesn't sound like they were trying to skirt the edge of what the ethics committee would allow, which is how I read your comment. Please let me know if I have misinterpreted.

As to possible alternative methods, those include freezing, which could be quite prolonged and painful, and blunt force trauma, which could be difficult/ambiguous to perform correctly and confirm correctness every time.
