Pretty crazy with Juul, WeWork, DoorDash, and Uber / Lyft all struggling (or showing their true colors) that all the things they sought to kill are coming back. Taxis, cigarettes, picking up your own food! It's amazing to me that people were having food delivered from a half mile away.
This essay jibes with the thesis of “Selfish Reasons to Have More Kids” [1]. It’s a book that nudges you to have one or two more kids than you were otherwise going to have.

> This reads to me if I could get a Nuclear Fusion reactor in my ship that has 10 times the power my Max Speed would still be the same.

Hull speed is a pretty simplistic approximation of the actual physics behind it, but generally the rule holds: A displacement hull cannot exceed its hull speed. What will rather happen is that the bow wave will pile up and eat your energy. It’s actually a problem if a very powerful boat pulls a smaller one, the bow wave on the smaller boat piles up, making the smaller boats bow rise up until the stern slips under the water and it sinks. (Or something else gives in under increasing strain before that happens)

Now, other hull forms can be built: glider hulls for example that glide on the water surface (think fast sports boats etc.), but scaling those up will certainly be problematic if you’re trying to aim for high carrying capacity. Cats/Multi hull designs sort of cheat the physics: the determining factor is roughly the length of the water line and multi hull designs obviously have more waterline for a given total length.
Could you please link an article that talks about what happened with the Nginx author?
The US used 3,911 TWh in 2015, or 10.72 TWh per day. Base load is about 40% of daily average.

Assume the worst case of only solar- that baseload also continues during the day, so about 30% of it would be powered by solar. That leaves 28% of average load that would need to be supplied overnight, or 3 TWh for the entire US.

The current installed cost for grid scale batteries is <$500[1]- $483/kWh for the 129 MWh battery in Australia. Batteries in cars are <$200 at the pack level. At $500/kWh that's 1.5 trillion for the entire US. Well within manageable for several years- far less than has been spent on Iraq, for example.

There are many reasons to believe that batteries could easily last for tens of thousands of cycles if properly specified[2], but current batteries are specified to ~5000 cycles to 80% degradation. Adding 20% capacity every 5000 cycles would cost 6 cents per kWh of system throughput.

By comparison, the EIA says that Nuclear costs 8 cents per kWh today[3]. By current measures battery storage is cheaper than nuclear (not counting initial generation), and that's not even counting the massive reductions in capacity that would be enabled by other generation and HVDC transmission.

> As a couple examples.... The laegest solar plant in Arizona produces only 10% of its peak summer power in the winter.

That's a lie. The lowest winter output is 37% of peak summer output[4]. The variation is HIGHER in the summer than the winter; +55% in summer and -45% in winter. Power consumption in Arizona also varies at the same time (because that's how the plant was designed to produce power) by 25-30%, so the majority of that variation is simply proportional to normal load.

What a moron
> I’d really rather see these called what they are: educational graphic novels.

That’s quite a mouthful.
Maybe. Or maybe child molesters, like most criminals, are criminals because they have a pattern of making poor life decisions and hence it’s perfectly normal for them to make “amateur” mistakes.
let's see what will happen when there is nothing to steal :-)
> I took my son out when he was 5 days old and I brought him everywhere since.

Generally, this is advised against to minimize chances of the child contracting a virus or bacteria while there are no good treatment options in the first few months of life. Also, putting them in a vehicle increases their risk of being in a collision, which has the same problem of having few good remedies, so playing it safe is considered OK.
> Before I had kids, I had moments of this kind of peace, but they were rarer.

My cynical take: certainly, for people with sufficiently stressful jobs, having kids is going to be less stressful. Still, it's far easier to switch jobs, or take up meditation. Plus, then I won't have that old stressful job!

> On the other hand, what kind of wimpy ambition do you have if it won't survive having kids? Do you have so little to spare?

This definitely reads like it was written by someone who made a lot of money, and then had kids. 13 years ago, he wrote: "Young startups are fragile. A society that trims its margins sharply will kill them all." You just need to have so much ambition you can afford to spare it, even though you're doing something where the margins are so thin they mean the difference between life and death!
This is a fair point. Taking it further, I also think it may just be that people with kids find "kid talk" to be a good default, safe topic of conversation with other people who have kids, so 50% or more of cases it actually makes them more interesting to those other kid-having people they can bond and empathize with.

Whereas I, who am not interested in that stuff, end up mentally putting them all into a single "boring" bucket, while the guy who can't stop talking about his 24-pack of Soylent gets his own separate "boring" bucket.
No one is saying it's not possible or not worthwhile; just that it's a very different experience in some ways.
For me it's not about some vague sense of "wanting to keep being 'fun'". I know that doesn't last forever. It's the fact that right now, I know there are things that are more important to me in life. And I think it's wrong to have kids if you can't make them the most important thing in your life, while they grow up at least.

I suspect that may change one day: once I've done certain things and had certain experiences and found certain elements of my personal happiness, maybe I'll have room for a priority shift. But I'm comfortable with my knowledge of my own needs. I think premature sacrifice and the inner conflict that follows is what makes for a bad parent.
How much would it be renting a car for a day in that area?
I don't really know, all of my side projects have been of the just-for-fun variety so I guess it's fair to say I can't relate.

Ask HN: How do you test your serverless architecture?
Hi HN,

We have a largely serverless architecture (API Gateway, Lambdas, DynamoDB tables, S3 buckets, nothing exotic) running small but growing production workloads.

It was very easy to get started, but we're really starting to feel the pain of how everything ties together when events occur, testing, slow feedback loops while waiting for CF to build everything, and proper rollback strategies for interconnected services.

We use SAM for local testing where possible and have some hacked together integration testing (e.g. fire event, then check if the expected record exists in the Dynamo table) but it is not smooth or scalable.

We are considering going with traditional server apps for some parts, but many of the same problems will remain.

I would be grateful to hear how you achieved a smoothly deployed, cloud-based architecture with 25+ engineers working across multiple teams, including best debugging and monitoring practices.

Thanks!
I think you are going to have a rough time if you separate energy and money like that. The only reason the dollar is worth anything is because of coal, oil, gas and nuclear.

What do you think happens to the value of the dollar when the physical supply of energy becomes unstable in the coming years?

Money is energy because debt needs energy to either have been spent in the past or energy being promised to be spent in the future.

The proportion between these is what makes debt money trustworthy or not. When the states around the world privatizes houses that is old energy (so far since the energy to heat the house is marginal compared to building it), but when the stock market goes up that is a promise for new energy.

Globally all money for old energy is saturated (negative interest rates) and now all liquidity is being injected into the stock market that promises that the future will be rich with energy.

The stock market (and all companies) is a promise to spend energy we don't have.

The only energy that is added to earth is sunlight, the only way to capture that energy are trees and plants.

All jobs are now meaningless because of the energy that we are wasting. And people now depend on wasting energy to have a job.

Do you see why energy is more important than money?

>On the other hand, what kind of wimpy ambition do you have if it won't survive having kids? Do you have so little to spare?"

It's a disingenuous argument. He acknowledges "attention is a zero-sum game" and that having kids has lowered his ambitions. Therefore, it's not a question of what is there "to spare" (implying leftover time/energy), it is a question of "how much are you willing to give up" to make room for the new priority.

It's not a question of ambition being strong or wimpy, it's a question of your tolerance for lowering your ambition.
They weren’t try to kill anything, they just wanted a piece of the action.

I had kids very young. They are nearly grown now.

I watched the people I went to high school with have kids very late allowing more structured time to complete their education as early as possible and excel to vice president positions in the corporate world. They excelled far more quickly and far more early in their careers than I.

In contrast my children will be out of the house and on their own while I am barely middle aged. Since I have never entered management in the corporate world but have grown two simultaneous careers, corporate software developer and military security analyst and network operations chief, I have a combination of skills I would not have developed otherwise.

In a bit when the children are out I can pursue all the career and startup dreams that young people dream of but without regrets or challenges of raising kids. Perhaps I am still naive, but I am certainly not rich.
I can't find the article that I thought had been linked to in the previous thread, but there was a similar article about depictions of the Moon that I read around the same time as the first postings of this. The point of that article was that people are really bad at depicting correct combinations of phase, orientation, and position for the Moon. It's actually pretty straightforward to get it right once you think about what the phase and position tells you about the Sun's position.
A level playing field is good for a challenge like this. Those that could solve it without these constraints are pushed to improve their existing approach. Those that don’t normally compete in these kind of challenges aren’t put off by a potential competitor having way more resources.
I think it would be just as devastating for the child to learn that they only exist because their father raped them into existence. If the money incentivizes the mother to give birth and potentially raise a child she might understandably otherwise detest, so be it. That's the least of the child's concerns once they are born.

I agree that late-stage abortion presents ethical issues. But before then, it shouldn't be up to governments and law enforcement to mandate what grows inside their population members bodies.
They do indirectly. A big gap between costs and prices invites competition, which lowers prices. Part of the "play" that ride sharing companies are making is building a moat around themselves so that they'll be able to discourage competition for a while.
Chromecast Kills Viera Link
After much hassle and frustration, I've finally managed to get my Panasonic TV talking to Panasonic Home Theatre via HDMI ARC, so TV remote controls Theatre volume, mute etc. However, as soon as I plug Chromecast into another HDMI socket, the link stops working - the volume progress bar on the TV still moves with the TV remote, but the Theatre volume doesn't change, and the Mute button doesn't work. Anyone have any ideas?
Easy: heavily tax solid waste.
So how’s that bubble been working out since then?

I own a car so it's not an issue of cost but convenience. Driving downtown is just not worth it (a broken window will ruin your weekend). I bought a car for leaving the city, not for going into the city.

I'd imagine renting the car is cheaper before you take into account parking, time, and potential theft. Car break-ins here are so bad people have become blasé about it. I went looking for a news story (there are many about how problematic property crimes are in SF) but found this instead:

I rarely come across such a terse, yet clear, argument why socialism requires force. But it is a false dichotomy, to conclude that the alternative is not to do anything.
Even knowing nothing, any sane password cracker would attempt five letter sentences long long before they even reached 30 character alphanumerics. And 30 characters is itself more than a thousand times easier to crack than 32.
Right. Think of “breeding” as the complete act of making autonomous organisms. If your children can’t survive without you, then in the evo-bio sense, you haven’t finished “breeding” yet, because the ability of your genes to be passed on still depends on facts about your genome rather than solely on facts about your child’s genome.

Humans take a pretty long time to “breed” compared to most animals, since humans are born pretty non-autonomous compared to most animals. But there still comes a point where the probability of breeding success of a child becomes entirely dominated by the factor of that child’s genes, over the factor of the parent’s.

Also note that, just because this effect exists, doesn’t mean it guarantees that it will be an effect in the direction of longer health-span in every organism. In fact, in many organisms, the organism is wired to die as part of the breeding process, since dying better guarantees success for the offspring! (Some because they no longer compete with their offspring for food; some because their body decays and fertilizes the spawning grounds, leading to a bountiful harvest for their children; etc.)
I met a person in a similar situation via a mountain bike group where I live. Kids are out of the house and now he has time for bike riding, date nights and, being in his 40ies is still fit, healthy and very active.
Kids demand a lot of time but can be remarkably unselfish. My 3 y.o. daughter made my bed this morning and tries to help me if I seem tired. We help each other out, and parenthood opened me up to a way of living that was less self-interested.
Isn’t this what read mode is supposed to be for?
I wish people would stop using the term “overpriced”. Apple sets the price. Their sales targets and subsequent results dictate whether they have priced it appropriately. We will probably never know if it was overpriced.

But we already have a word to describe something that costs a lot: expensive. Really we should be asking if it is good value for money.
Pandoc + Zotero + better-bibtex user here. This is indeed nice, thanks. One possible problem I see (but I am not sure what could be done to solve it) is that often metadata are incomplete or partially wrong, and I need to fix the resulting bibtex entry by hand. This would be difficult with your tool, I think. Have you thought about this?
It's very socially unacceptable to admit you regret having kids. But the internet has enabled that viewpoint to surface through anonymity. I see having kids as a huge gamble. If you realize it's really not for you, there's no way to go back. I also question the morality of bringing an intelligent, sentient being into this very troubled world without their consent.
I use K2pdfopt to convert scientific articles to a format (mostly) readable on my Kindle.
It varies from person to person. For me it was mostly a sacrifice in leisure time. But I spent most of my weekends hanging out with friends and playing games. If you spend 24/7 focused on career, then yeah you're an extremely ambitious outlier and will have less time towards those things you listed.

But in my experience most people actually spend a lot of time hanging out with friends or doing nothing at all. This is where sacrifice of leisure and time management kicks in. I don't actually work on side projects any less than before I had kids. But I play games, hang out with friends, and do nothing a lot less.
yeah sorry, should have said "last i remember".

> We have been posting multiple articles on our tech blog, explaining what we do and how we do it in great details.

has there been a followup to any of the points brought up in the reddit thread?
When (some) people claim the Mac Pro is overpriced, what they're really reacting to is that there isn't an upgradable tower Mac available at a price point they can afford. There are people who don't need Xeon processors and multi-terabyte SSDs who still want the option to swap and upgrade components but can't afford to start at higher than $2k-$3k.

The Mac Pro isn't overpriced for what it is, but its overpriced for what many people want.
This sounds an awful lot like autism man.
I just read half of the last paper (and skimmed the other half). It is surprising that the paper does not use the term "information theory" even once. The research basically bumps into the established facts that properly hiding or destroying information is really hard.

Advertising industry has known this since ancient times. Military signals intelligence has been essentially built with that tidbit as its core. Even weak proxies are formidable if you have bucketloads of them to choose and combine from.

Now, let's make one thing clear: I am not a FB apologist. In fact, I find the modern advertising systems abhorrent, immoral and outright vile. But even then, this article felt like the authors chose to miss the point. Hiding information is incredibly difficult - and conflating "information theory is damn hard" with "FB[ß] are evil and/or immoral" feels intellectually dishonest.

For what it's worth, I would actually love to see research _and_ well sourced articles about the practical net effects of information theoretical attacks, intentional or not, on the human populations as observed through the various e-stalking platforms.

Hey guys. Anyone else have the experience of having kids, getting a burst of energy, but of course all that energy goes directly back into the kids and house, and you have absolutely no life for 3-5 years or more? Because my kids are 2 and 4 and so far it's been 4 years of no life, no freelance clients, almost no learning/hobbies, just 35-40 hours a week of working as much as I can at the office and then everything is about the kids. Until everyone goes to bed, then maybe I can think about something interesting to work on for a couple hours before sleeping well less than 7 hours of healthy sleep. Or do you even give that up, and as soon as the kids are in bed it's time for the bedtime routine for yourself?

Just looking for some dads who can relate and maybe give some wisdom on the subject of having young kids and losing your ability to work on something interesting--which to be fair I never did before having kids because I was unmotivated, having not had that burst of energy yet...
I love this article, and I've experienced parenthood quite similar to Paul (I have an 11 month old), but I disagree with his statements on ambition, maybe it's because he was so full of ambition and success prior to having children. But for me, I now feel a great drive to provide this baby with all the opportunities and experiences in the world. And I can't give him those things without great professional success.
It can be true, but for a gene to reach fixation, it has to be selected for, i.e. organisms without it have to die before breeding.

So this effect might work out if you have a lot of isolated sub-populations, and the ones that live less long suffer extinction, while the ones that live longer go on to eventually reconnect and breed. But it doesn’t really work in a “liquid market”, because free riders without the longevity genes will be just as successful at breeding (due to the existence of the long-lived species members) as the ones with those genes.
Attempting to murder someone is still attempted murder, even if it was impossible for the attempt to succeed.

Let’s say you and I both want to kill Bob. I sneak into his bedroom at night and smother him to death with a pillow. Bob is now dead and I sneak away—I have committed murder. Shortly afterwards, you sneak into his bedroom and shoot him multiple times with a gun. In this scenario, you are guilty of attempted murder even though the intended victim was already dead, unbeknownst to you.

Many stings rely on similar principles. People who steal bait cars don’t actually succeed in stealing the car, nor do johns who solicit streetwalking undercover cops succeed in buying sexual favors from them.
