IIRC, reflection of the sun off water is 5% when directly overhead to about 65% when at a glancing angle (low on the horizon). I prefer to close my eyes and aim my face at the sun for about 10 minutes a day if I'm working indoors all day plus whatever incidental sunlight I get. I have SAD during the winter months and use a full-spectrum lamp, then.
People who spend more time in the sun have a low-moderate risk of melanoma, but higher risk of other skin cancers, vs those who spend more time indoors having a lower risk of non-melanoma skin cancer and a moderate-higher risk of melanoma cancer.
Exactly. I suspect the lack of understanding or overcomplicating the reason the birthrate is declining may have something to do with the much higher than average salary of the average HN commenter relative to the average worker's salary in the US. It's common for people who need to go to the doctor to avoid going to the doctor because they can't afford it. A baby is an order of magnitude more expensive than that and an ongoing expense of doctor visits and potential ER visits among other costs and logistical issues.
I don't see how the US can compete with China on sheer production and access to manufacturers and suppliers of tech, compared to cities like Shanghai, Qingdao and Shenzhen, among others. It's like a candy store for engineers. Building a single plant just isn't economically feasible when you have so much uncertainty from the chaos at the WH. Not to mention, this will take a decade or much, much more.
A better way (IMO) to do it would have been tax incentives to build US plants to move manufacturing back in the US, have research university programs as feeders for tech innovation centers, and funding for technical colleges to expand their programs for skilled labor needed instead of gutting multiple agencies that would have overseen/guided this expansion. And oversight, of course. And attainable goals set in contracts to receive funding, not just, "here's a pile of money we'll forget about in 4 years."
Digikey, McMaster-Carr. Lots of other options. they might not have a store front in your city, but they can get you everything you need for reasonable prices.
No sane company wants to work that way. Just in Time is a great thing, you shouldn't be over nighting anything you should be working so that you know when you need each part months in advance. If you can get a part in China faster it is because someone has expensive inventory and that is a bad sign in general. You do of course need some emergency supply and such, and retail customers don't plan in advance well - but a business shouldn't be buying retail anyway.
It's not JIT, it's that planning works on months advance notice like you mention is in large part because the supply chain is global and shipping takes a lot of time. When digikey has a month lead time because some component is out of stock, it often means "It's going to take a month for this to arrive from the factory".
In China, you can just go down the street to the factory.
As for shipping overnight, it's incredibly common in R&D and repair.
Only if the factory in China will make that thing today. If they are one their New Year holiday (I forget what they call it) you won't get anything. If they are busy making something else you won't get anything - unless by human factors you can convince them to work for you instead of meeting their promises to other customers.
Sure, but you don't have to wait 6 weeks for a cargo ship.
The concept of having centralized full-chain production for enormous productivity boosts is not some wild concept, it's ancient and well known. Industries have clusters because it benefits everyone in the cluster. The US has very few and weak manufacturing clusters.
Shhh! Do you want to kill AI? All the C-suite and middle management need to hear is that "My QoL has never been better since I could use AI at work! Now I can 'quiet quit' half the day away! I can see my family after hours! Or even have a second job!"
Once 23andMe gets sold, all of that data belongs to whoever owns it and they can sell it to whoever they want. Perhaps to the government where they can do a warrantless search to find a relative of someone who may have been at a crime scene. Or to other governments. Or to insurance companies who want to play deny, defend and depose. I get that a lot of genetic information isn't predictive, but not all of it is so questionable.
It has statutory limitations, subject to change, in how it can be used to discriminate against you. But those are tightly defined. It couldn't be used to deny you employment or health insurance, but could be used to deny you housing or life insurance.
I'm really not. The government consists of many people with a range of ideologies and ethics. Are there problems? Of course. But, the government has checks and balances, well, HAD checks and balances, separation of powers, and a Constitution that limited those powers. I'm more afraid of the corruption of the SCOTUS with dark money and a religio-fascist movement of persuasion and influence toward members of the SCOTUS, Congress, Judiciary and the Executive. It is a handful of billionaires who are driving this race toward authoritarianism.
The difference is that there are culturally inappropriate things to say--that is, things that people who aren't completely toxic bigots generally agree you shouldn't yell in public, and then there are things ON THE LIST the right wing government fascists are going to kick your door down for uttering to two people online.
