>you're going to have to figure out what to do with all the leisure time

Not an issue for me, nor anyone else I know who has retired early. Maybe the same sort of energy that supports early retirement also leads to a fully engaged post-retirement life.

As long as you love to learn or create (or both) you will have a shortage of free time, even in retirement.

Off the top of my head, I spend time on: foreign language, guitar, writing, blogging, photography/videography, programming challenges, fitness, meditation, cooking, history, math, politics, biking, kayaking, hiking, golf, travel, volunteering, reading books/magazines/news, watching movies/shows, surfing the web, home improvement and repair, investing.

And that's just the fun stuff. There's still bills, taxes, paperwork, repairs, laundry, dishes, on and on.

Honestly, I still don't have anywhere near enough time and am annoyed by how much time sleep steals. I have no idea how I went 30 years with 50 hours lost every week to work, not to mention raising a family.

It's a trite saying, but true: you won't be bored unless you're boring!
woohoo, HN mutual learning :-D
During the era of freeway construction they usually built the enormous interchanges through marginalized neighborhoods. Nobody with political power cares because they don't live there; nobody who lives there can prevent it happening.
For anyone interested in this type of stuff, I can recommend reading Drive.

Briefly, human behaviour can be motivated for extrinsic and intrinsic reasons. The rewards in this article are extrinsic motivators. Exploring is rewarding in an intrinsic way; it is a strive towards autonomy, mastery, and purpose.

In adults (and in older children) applying extrinsic motivators kills intrinsic motivation. Once the extrinsic motivators stop coming in, there is no desire left to do the task. Intrinsic motivation is practically infinite, as long as the environment is set up right to enable it.

Extrinsic motivation also tends to produce behaviour that does the bare minimum to get the reward (or avoid the negative consequences) whereas intrinsic motivation is what makes us want to excel.

Of course, I've skipped many important points and not countered any counterargument here, but I recommend reading Drive first if you think you disagree.

But the worst part of it all?

The schooling system, with its grades, signed slips, and whatnot, is set up through extrinsic motivation to teach obedience, conformity, and smothering the intrinsic drive so necessary for the creative work we will expect from the children later in life.
Thanks for sharing. I skimmed the article looking for a specific set of info but may have missed it: how do bodies naturally/organically generate vitamin D and can that be sufficient or are supplements necessary? (E.g. I surf 5 days a week with sunscreen and go for walks regularly. Will I have enough vitamin D or should I supplement?)
With only 37 adults, there probably wasn't enough power to say anything significant about gender
This is even more relevant after 30 years.

The Data Dominates principle is the key, everything else just follow, including n are usually small and preference for simple algorithms.

Nowadays we have exactly the opposite, which is understandable since the field has been invaded by uneducated amateur posers.

> sorted std::vector

But inserting into sorted std::vector is o(n log n) in worst case right? (As you have to binary search the position and move other elements). But a hash set with linear probing can give O(1) (amortized) access, while usually maintaining an invariant like total_size > 2*n. I don't think that would be such an impact on cache locality. Linear probing doesn't require linked lists.

Of course this is given that you have a data structure in standard library. But at this point I think hash sets are pretty standard.
Yeah, the more I engage in this thread and topic, the more I'm learning how it seems the USPS does a pretty darn good job.
FirefoxOS was a good idea: a portable phone system that could run on cheaper hardware than Android could, built with web technologies instead of Java.

Then hardware manufacturers started producing cheap hardware that could run Android with acceptable performance, thus eliminating the price advantage for FirefoxOS, before that OS could take off in third world nations.
Interstate highway construction slowed dramatically in the 70s after federal funds largely dried up except for the remaining critical arteries like the Colorado I70. Since then, a dozen highways proposals have come and gone because of eminent domain and environmental impact lawsuits in Southern California alone.

The I710 expansion, for example, was finally axed a few years ago after six decades of opposition from South Pasadena and the surrounding cities. At one point the state was considering a plan to tunnel under the town for about a $billion a mile because the opposition was so intractable (well funded and connected) before Caltrans gave up and started selling all the housing they'd been accumulating for decades for the project.

2/4 rounds (and the overwhelming majority of the $$$ raised) were years after the EMC acquisition, and immediately before the IPO. Not really what people think of when they talk about raising VC.

The 5 million and 20 million rounds in 2000 were strategic investments from partners who were going to resell ESX, and were done for reasons other than needing working capital. IBM and Dell were the 2 partner investors, IIRC.

While CalDAV sounds simple on paper, it is anything but. That explains the complexity of most projects related to it.

Things like DAVdroid provide a syncing ability for Cal/CardDAV to Android.

There is evolution-data-server and SyncEvolution for regular GNU/Linux.

Good luck in building something lighterweight, I'd be keen to move to it from NextCloud too :)

There are multiple ways to solve this problem. It’s not a showstopper.

1) Bury the lines. Basically isothermal at depth.

2) insulate the tube and maintain stable temperature

3) use materials that don’t drastically change length with temperature

3) allow the tubes to change length. Put them on rollers.

4) use vacuum expansion joints just like us common in vacuum engineering.

People act like vacuum is this new thing. Physicists (well, Engineers/technicians hired by physics projects) have been making really long tubes with extremely high vacuum and incredibly high tolerances. This is easy in comparison.

I have not researched this in many years but not all that money has been payed back by Ford, GM and so on. Just recently Ford moved back another payback claiming Corona as an excuse.

I assume the majority has been payed back but I have not followed this in exact detail. However the point stands that Tesla has not received the majority of government help.

> When people complain about Tesla being taxpayer funded, they're generally referring to EV incentives, not the DoE loan. Tesla has indeed been supported quite a lot in that way.

Frankly, this is just a wrong believe people have. Tesla has the exact same EV incentives as the competition, that amounts to 7500$ per car. Tesla has long run out of these, as they only cover 250'000 vehicles and then fall off. GM just like Tesla has made use of this and has also almost ran out as well. Ford still has many left and will and does make use of that to make their upcoming Mach-E a more price competitive product.

So there really is nothing Tesla specific and the competition has profited just as much.

Next up, there are credits based on fuel standard compliance. This existed long before Tesla. These are competitively sold for California (and other states) and Europe. Tesla does make a money from these this is not from the government or tax payers, rather other car companies who do not comply with fuel standards. Its a fine for car makers who fail to comply with regulation. But again, all car manufactures have the exact same opportunity to engage in that market.
Yes that's about right :)

Yes, that's why I said-
>made to work beyond office hours to be eligible for the incentives

I said that based on complaints I received from Indian drivers,
• Need to work X hours to be eligible for incentives, incentives are used to meet fuel costs.
• Algo punishes when rides are not taken during peak hours.
• Majority don't own the vehicles, they are working office anyways for someone who owns it.

Anyways, main issue is many of the drivers are out of their work due to COVID-19 and if they were employees; at least some protections would ensue.
Funny how sometimes I can be so embedded in my emotional experience of something that I can forget that others may have very different emotional experiences on the same thing.

After all these comments, I'm probably still leaning towards wanting it to stay public, but more open to privatization, and still quite vehemently unconvinced that now is the time to make that change. Again, thank you for all the conversation.
I think it gives as much hint as you can without causing a massive wave of outrage:

>But there’s the thing: If socialization processes can instill in individuals a victimhood mindset, then surely the very same processes can instill in people a personal growth mindset. What if we all learned at a young age that our traumas don’t have to define us? That it’s possible to have experienced a trauma and for victimhood to not form the core of our identity? That it’s even possible to grow from trauma, to become a better person, to use the experiences we’ve had in our lives toward working to instill hope and possibility to others who were in a similar situation? What if we all learned that it’s possible to have healthy pride for an in-group without having out-group hate?

Basically, focus on your strong sides rather than weaknesses. Find people that make you happy and spend time with them doing things that make all of you happy, instead of focusing your attention on those who offend you. Pretty sound advice, IMO.
The "exploring" is because they're told to make a choice. Is there something similar to developing object permanence but with abstract concepts or probabilities that happens after that age?

While I think you're right (in terms of laws around abandoned property) it's worth noting that the gangs discussed in the article only steal cardboard in large quantities. At $80/ton, even a pound of cardboard is just 3 cents.

Now, in poorer countries, people absolutely do collect individual pieces of scrap cardboard, even at those incredibly low prices. But that's more related to a much, much sadder discussion about income inequality. If you want to see what that looks like, living on scraps from the streets, Reuters recently did an interesting photo piece: https://www.reuters.com/article/us-russia-homeless-widerimag...

There's a second reason. The hyperloop tubes can slide back and forth on the pylons. If you shake the ground underneath them, the pylons can move around but the tube (tube system) stays still (like moving your hand underneath a baseball -- the ball stays still, rolling).

Signal separation techniques for characterizing cyclostationary signals are also more robust to noise. For example, analysis of the second order FFT can resolve the signals of incipient faults in rolling bearings because it can resolve the signals of the bearing components rotating (at a much lower frequency than the shaft) whereas simple FFT analysis would generally only measure the magnitude of the structural resonance of the machine, with spikes at the mains, rotational, and slip frequency.

Well, one difference is that the Supreme Court basically killed the law as written because it conflicted with the 1st Amendment. Can you find anyone who has been prosecuted since the case I linked? Prosecutors aren’t going to use the law anymore because any judge all over the country will reject the argument. Look up how legal precedent works, I guess...

Do you think that will happen in Hong Kong? The Hong Kong law is also far broader and more vague.

Look, I don’t think I’ll be replying to you further. You’re not trying to actually learn anything, you’re extremely disingenuous, and you don’t raise any interesting points, or really any coherent argument at all. If you want to learn more about the difference between China’s legal system, or the neutered Hong Kong legal system, and the US, do it on your own. I’m not going to hold your hand anymore.
If you read the internal PDF, it's very clear that they reduce money spent for developers and increase money to get end-users.

I don't envy Firefox here... despite being fan-favorite of nerds, it is just about 9% on desktop and declining, while <1% on mobile.

In total, it is less than 1 percentage point more popular than Samsung Internet (the weird bundled Chrome thing on Samsung, with 3 percents).

I'm a member and I certainly don't regret it. I also only shop a few times a year, I paid the $20 dollar lifetime fee to be a member about 4 years ago and I've earned over $150 in dividends. I primarily choose to shop at REI for their 1 year return policy, that buys a lot of piece of mind when you buy a different type of shoe, a backpack that you want to test out, or maybe a sleeping pad that looks comfortable in the store but may not be comfortable in the wild.

We had a dishwasher with auto-dispense where you pour the whole bottle of detergent into a reservoir and it would automatically dispense what was needed.

Well one day it was getting low I poured a new bottle in and all the dishes weren't getting washed. I called the detergent company to report a defective bottle, but turns out there was some sort of formula change due to a new regulation. Apparently mixing the two together in the auto-dispenser causes them to harden and clog the dispenser. So I tried just pouring it into the manual dispenser, slightly better but the dishes weren't really clean. I called my dishwasher repairman who just told me to buy Finish tabs and we would be fine.

My mother called me weeks later saying that six of her tenants complained that their dishwasher was broken and she had already replaced one (two of the dishwashers were less than two years old). I told her to just gift them all a tub of tabs from Costco which worked.

That's an isolated incident. I don't think the cardboard they've been collecting all this time regularly will have day to day shifts in values that cause them to randomly discard some in the forest.
Personally, I don't want a smart city, I already have a smart phone and that's enough for me. When I walk outside my apartment, I want to be escaping from my technology as much as possible, rather than being exposed to more of it. Give me trees, bike paths, and metal benches, not more screens and automation. And a lot of the automation they talked about sounds like it would be taking away low skilled jobs, which we are going to need more of unless someone implements UBI.

Maybe I'm just getting old though, it's all downhill once you hit your 20s.
Launch HN: ReadyKit – Build your emergency kit from the best gear on Amazon
Hey HN, launching my quarantine side project today.

ReadyKit is a community-curated emergency preparedness kit on Amazon. Build your survival kit, first aid kit, and natural disaster kit from the best products on Amazon.

https://readykit.org

How it works so far:

* It's free—everyone from casual preppers to doomsday preppers are invited to build a kit

* Adding new products from Amazon is easy. Simply copy and paste Amazon links and the title, image, and price will be pre-filled

* Earn Amazon affiliate fees on your recommendations by adding your own Amazon Tracking ID under Edit Profile

* Kits are easily shareable with fellow preppers, friends, and family (e.g., https://readykit.org/jesse/survival-kit)

* No spammy emails, paywalls, fake accounts, or notifications!

The idea is that anyone can add recommendations while human curators and a simple algorithm surface a mix of the highest value gear from reputable brands.

E.g., I recommend Big Agnes tents and sleeping bags in my kit because I’ve used them on wilderness backpacking trips and know they are high quality, durable, and have a lifetime warranty. I also recommend Sawyer and Aquamira for filtering and treating water, 3M respirators and Honeywell air purifiers for wildfire smoke, etc.

I would love to get your feedback and ideas for improvements!

For those who are interested, it was built with React, Redux, Python, Django, and hosted on Heroku and AWS (S3 and Cloudfront).

P.S. There's a fun easter egg with CSS3 filters if you create an account and turn on Dark Mode in Settings.

Chiplet Reliability Challenges Ahead
Nobody ended Eich's means of making a living, ostracized him from society, or denied his humanity. He remained Mozilla's CTO after his donation became widely known in 2012. There wasn't any significant protest until he was promoted to CEO in 2014. He wasn't fired and still reprimands people who say he was. He's been another browser company's CEO since 2015.

Eich probably could've defused the situation if he just apologized. Instead he wouldn't even say he wouldn't do it again.[1]

People didn't refuse to follow Eich just because they could. They didn't even refuse to follow him just because he hurt people. They refused to follow him because he still thought what he did was right 6 years later.

Jews were oppressed because of who they were. Eich faced a choice because of what he did.

Exactly this. That’s why The Boring Company is focusing on reducing the costs of tunneling dramatically. And they started by just using existing technology. With that (and without the cost inflation that many corrupted projects experience), they were able to achieve about $10 per mile of tunnel. A lane of highway per direction is $1m to $8m depending on if it’s rural or urban.

They’ve developed a new machine, Prufroc, that’s supposed to be much faster and capable of “porpoising” (ie angling back up and curving straight) so you can avoid having to excavate a deep station through other means.

If they can get the cost equivalent to a typical surface street in urban areas, they can now compete with surface streets. Much easier to autonomously drive in purpose-built tunnels. Or put a train or a bike trail or moving walkway or whatever.

So they are actually trying to solve the right problem. And using cars is a good idea because cars are really cheap per passenger in terms of upfront capital cost, and they meet the speed, autonomy, safety, and electrification requirements while also allowing use on just regular paved surfaces. If the one-dimensional autonomy works well, they might be able to reduce follow distance at speed enough to exceed a highway lane throughout. And with high occupancy, also a typical light rail train or whatever.

Would be kind of neat to have autonomous driving at 120mph immune to weather and with low enough capital cost that we could afford to crisscross the country with them, without much impact to existing land uses. A clear win if it works. Actually, a clearer win than full autonomous driving on existing roads, as that might quickly clog up surface streets. Plus this is probably technically easier than perfected level 5 autonomy which is still a sort of open ended problem.
