There's multiple comments in this thread pointing to Chinese car manufacturers paying under $200 for their LIDAR hardware.


Price without specs per radian is meaningless.


$200 is still a lot when a bunch of cameras cost maybe $20.


$200 to enable better FSD vs a decade of struggle to get FSD only partially working with $20 cameras. Which one do you think is more expensive overall?


The fact that we still do not have a significant number of cars with LIDAR on our streets somewhat proves which approach the auto industry considers viable for business.

I am much more curious about the next ten years. If we can bring down the cost of a LIDAR unit into parity with camera systems[1], I think I know the answer. But I thought that 10 years ago and it did not happen so I wonder what is the real roadblock to make LIDAR cheap.

[1] Which it won't replace, of course. What it will change is that it makes the LIDAR a regular component, not an exceptionally expensive component.


The fact that the only working self driving system uses LIDAR might say even more.


1) make it work

2) make it right

3) make it fast (or cheap in this case)

Elon thinks his genius intellect allows him to skip to #3.


> $200 is still a lot when a bunch of cameras cost maybe $20.

Anything except the lowest end car will cost $20K or more, so $200 is one percent of that price.


I mean, I'd rather be building a $30,200 robotaxi that works than a $30,020 robotaxi that doesn't.


You won't get rich with a $30,200 robotaxi, you won't even have a viable business. The game is the mass market and there the usual unit of currency is not cents, its tenth of cents.


Even if your robotaxi only manages 2000 rides that’s still down to just 10 cents a ride to cover the cost of hardware.

It’s nothing.


All taxis are variants of mass produced cars, that will not be different for robotaxis. The mass market is the enabler and there every tenth of cent counts.


I'm almost afraid to ask, what are living cadavers?


Brain death without cardiac death.


Presumably people who are on the verge of death and beyond any kind of proven treatments. They're technically alive but have a very short predicted lifespan.

You can try a novel treatment on those but at the same time are limited by ethical concerns regarding pain and future survival (if the transplant "works", you are now in a tricky situation, as you can't easily do anything that has the potential to make the situation worse... and given it's uncharted territory, anything has the potential to make it worse).

Brain-dead people don't have such limitations. You don't have to worry about causing pain nor shortening potential survival, so you can try things that are likely to "kill" them (cause the transplant to fail, or other issues) and learn from the outcomes.


> Brain-dead people don't have such limitations. You don't have to worry about causing pain

Fortunately determining brain death is a problem with a clear-cut answer with a clear line dividing “brain death” and “not brain death”. Right?


No, but you can measure pain response, and predict pretty well if they ever wake up, so well enough for this.


Actually it’s less the science of it that concerns me, but whether procedures will be rigorously followed.


Agree with you on that. People can say that there is a procedure, but verifying that they are following it is another matter. Also curious as to the process for volunteering people for such experiments. Like if there is some paperwork that the family signs off on.


And in China they can just decide they will never wake up regardless.


Very good point - I don't have an answer for that. But I'd say if there was a choice between killing a person who is very much alive and conscious by our current standards, and one who is "brain dead" by the same standards, I'd still pick the latter.

Part of it is a choice you make when choosing to donate your body for research. There's a chance brain death can be determined incorrectly (though in this situation it's likely the same determination will be used to withdraw life-support, research donation or not).


This is what holds us back.

If I'm ever declared brain dead, I want scientists experimenting on me. That's a much better use than giving organs to just a handful of people. It pushes the salients forward for everyone.


I mean for experimental organ transplants we could literally do both though.


I bet it's Usenet users. WinRAR can split large files into chunks that are uploaded as separate Usenet messages.


And also have parity built in for file recovery. The alternative will be to use par2 to create parity files.


The parity files are the killer feature for me. Probably 95% of the downloads from Usenet end up needing them.


7z also does this now FWIW

I'd still bet it's Usenet users that installed WinRAR way back when and have stuck to it ever since


That's me. But now everything is done automagically by nzbget and I use nanazip on my Windows desktop.


The trick is to to find real locksmiths, with a real storefront, preferably ahead of time. If you just Google emergency locksmith and your ZIP code or location, all of the top results will be scammers in unmarked vans. This is an old scam, it's got its own Wikipedia page: https://en.m.wikipedia.org/wiki/Locksmith_scam

There's been some reporting about these fake listings on Google maps: https://www.cbsnews.com/news/google-maps-fake-listings-lawsu...


You haven't read World War Z! Zombies don't need to swim, they just walk on river and ocean bottoms. When there's billions of them, a few will make it anywhere.


I dunno I cant paddle in waist high water with scabs or cuts without a little fish taking a chunk out of my leg, and zombies are 100% decaying flesh.


Something like 40% of the homeless nationwide are actually working, employed, but unable to build up enough savings to rent an apartment.

Here's just one source I found on: https://endhomelessness.org/blog/employed-and-experiencing-h...

I got a tour of a homeless shelter a few months ago and the folks running it mentioned that one of their jobs is to wake up specific people at 6am, 7am etc so they can make it to work in the morning.


Sounds cool :-) I think we'd forgive you for providing a direct link to this product.


There's a bajillion of them around if you search "neck cooler" or similar. Very simple product sticking a few commodity items together. Some do only have fans though.

When I looked a while ago there wasn't really a clear winner or high quality unit. There is the "Coolify" series that are much more expensive but still somewhat middling reviews overall.


No link, I have the Ranvoo Aice Lite. Couple hundred bucks on Amazon.


That works great for your basement but what's the impact of low humidity on ancient books?


You definitely wouldn't want to go all the way to zero. 30-50% RH is generally the sweet spot for archival purposes.


The library also talks about having a huge mold problem, so it would likely be positive.


Looming human extinction? Bro, all you need to fix this "problem" in the West is more immigrants.


Immigrant countries are experiencing the same trend. Soon countries will be fighting for immigrants.


If there's no culture, development level, and way of life preferences, for different national states and ethnic groups, and humans are just interchangeable units, sure. Just add as many immigrants as you want, problem solved.

Adding, say, to a country an additional 10%-20% of its current population in people from another culture, to be the younger and more fertile group, in an aging domestic population, would absolutely go without issue.

At least, if we also ignore that immigrant origin countries all see fertility drops, many projected to reach sub-fertility rates themselves soon, of course.


I read here (on Hacker News) that the stool test is actually really valuable and cheap enough to pay out of pocket prior to trying to justify an out-of-schedule colonoscopy.


Is it at home ones or ones that you send sample to get sequenced?


Not to mention the prepare for a colonoscopy is not pleasant.


And colonoscopies are invasive procedures that have their own risks. Perforated bowel can turn this "routine" procedure into an emergency.


Gentle reminder for Australian folks here, you can get a bowel screening test kit for free, if you're between 45 - 74 years of age.
