The large families I know each have one full-time homemaker (Mom or Dad) and no other family nearby. They depend heavily on the older children to help out.

For instance, an 8-year-old can do laundry (except for carrying the basket), or vacuum, or prepare sandwiches for the entire family's lunches. A 12-year-old can change diapers, assist in the kitchen, or keep an eye on younger children of any age for an hour or two while Mom and Dad are a couple rooms away cooking or doing other chores. In some states, a 15-year-old can drive siblings to school; and in most a 17-year-old can drive them to other destinations.

One thing I've noticed is that the children in these families are much more mature, responsible, and independent than children of similar ages in 1-3 child families.

I used to have back pain from sitting too long. So I fixed the problem by going to gym (couple of times a week) and taking short breaks every 45 - 50 minutes while at work. Just going to get a glass of water, visiting the bathroom, moving to talk to a colleague did the trick. Also push ups, almost daily, twice a day doing 20 push ups really made a difference.
As a customer since a long time I agree that Spotify should become a platform, but I doubt they will succeed due to how they shipped previous features. Anyway, the three features I want:

- Lyrics, and integrating Genius for 1/100th of the tracks in the catalogue is not enough.

- Concert tickets, in a smart and transparent way. A musician I'm listening to a lot is coming in Germany? I want a notification, a way to share it with my Spotify friends, and a way to pay in one click.

- Listen to songs that are only available on Spotify. I am so pissed off by Apple doing that and I think it sucks, but Netflix did it and seeing exclusive versions/remixs/concerts via Spotify would make the platform incredibly valuable to me.

Sounds hard? Well doing an IPO and competing against Apple, Amazon, and Google is not easy. The smart playlists are great, the brand is valued, time to go further.

Fairly limited, I would think. There's a distinction to be drawn between a "home," and a "home address," in the case that said home is moveable. Legal notice typically is served to the latter.

Also, this ruling isn't precedential, because it's not in a court of appeals. Practically speaking, this means it only really applies to this single case, and possibly other Washington state courtrooms, but nowhere else.

> you are too lazy to make a massive effort to go see wild animals in their natural habitat

For the vast majority of people it's not being "too lazy" but simply not having the (financial) means to do a "real jungle safari".

Especially once you factor in children, which are often the target audience for zoos, paying for a jungle safari is quite a bit more expensive compared to just visiting the nearest zoo.

Mind you: I'm not disagreeing with your basic point of these places being cruel living conditions for animals, but I take issue with your labeling of the motivations for doing so (too lazy). In reality, only very few people have to financial means to make "real jungle safaris", even more so when you already have to take care of kids (which are expensive), a factor quite a few people on HN regularly overlook on quite a few issues. Not everybody is a well-paid coder/exec/entrepreneur (and it's naive to assume everybody could) with tons of disposable income, the vast majority of people mostly struggle to make the ends meet.

Sadly there are no easy "solutions" to any of this and for some children, it can be an experience which actually makes them aware of these issues in the very first place. I still remember seeing live Dolphins for the first time at the local zoo, and how sad and sick they looked compared to images/videos I've seen of wild ones. Years later it turned out that kid me was pretty spot on because it came to light that these dolphins had been drugged (and probably still are) so they can endure their living conditions [0].

I think there are two separate issues.

I don't know whether paying for someone else's lunch is OK according to regulations for meal stipends in Brazil. I wouldn't call that corruption off hand, but it might be forbidden. I defer to you on this.

Personally I live in Buenos Aires and I regularly spend USD 15 on a no frills lunch menu in a fancy-ish neighborhood (nothing fancy for the food itself, no desert, the kind of place where a group of 20 people from nearby offices have a loud lunch). From my experience Sao Paulo is more expensive than Buenos Aires, so it didn't strike me as odd initially.

That's out of reach for the statistical average of income from Argentineans, but it's not an amount that a congressman wouldn't be able to afford on their own dime. I certainly wouldn't get outraged at the expense or assume corruption - congressmen are paid significantly above minimum wage.
Ask HN: Fast Read-Only Relational Data Store
I don't mind if building the database takes on the order of days, but I'd like queries to be as quick as possible. If I get new data, I am fine rebuilding the database from scratch rather than inserting. (New data comes in on the order of months to years).

I have several related datasets that I'd like to query. The datasets are currently stored in flat files. The largest data set is 4 million rows x 20 columns, the next largest is 50000x1300 (or 650 million x 3 if "melted"). There are 5 bigger data tables, and several small metadata tables.

What sort of database would be best for this size and these goals? What additional information would you need before recommending a solution?
Well, I think there's a lot of promise in weather modification for the purposes of transporting fresh water long distances. I'm probably not ready to apply right now for that idea, but if someone is out there working on that, good job and we should chat.
By that time, actually, the four traditional TV networks were already quite disrupted by cable networks. Netflix was following a well-established non-major-broadcast-network model (e.g. HBO, USA, FX, Showtime, etc) that had achieved a lot of prominence already.

Some of the most talked-about shows in the country were only on cable.

I believe the term also refers to "mutt", a dog that is not purebred.
> Truck companies avoid this kind of thing because it's expensive to maintain pools of short-haul drivers at either end of the transport link. If you are willing to assume those costs/risks, you can already send freight by rail, which is an order of magnitude more efficient on fuel, and sometimes even a little faster.

Speaking only from the US perspective, I agree with most of this. But there are a couple things you're not taking into account:

1) Delivery variability for rail. While rail is much cheaper in terms of cost per ton mile, good luck getting an accurate estimate of when it will be delivered. Midwest to Pacific Northwest I've seen variability of a week or two for going halfway across the country. If they're delivering to you and are multiple days late, they still expect you to drop whatever else you had planned and get their rail car unloaded on a relatively short turnaround or they start charging fees.

2) Rail requires quite a large scale. Many factories aren't shipping out more than a few semis per day. Getting to enough to fill a couple rail cars would significantly increase the inventory levels.
This. 100%! I find whenever I have a career crisis, or lack of motivation, it is because of this right here.

So much code no matter where you go will be something like this. You'll have to make something work even though all the code surrounding your feature is a dumpster fire that is so hard to predict, that you'll pull your hair our worrying about all the ways your feature will break.

I am hesitant to ask this as it seems you only hear about young folks being accepted into YC and succeeding. But I also know that YC thinks differently - so here goes:

I am a 62 year old solo founder working on my fifth startup - all have been bootstrapped and successful to varying degrees. How much does age factor into YC's acceptance decision - if at all. What is the oldest founder YC has ever accepted?
Thanks!
> Online retail—including selling through Amazon—has helped him keep the doors open. (He bemoans the fees he has to pay Amazon for the privilege, however.) He estimates that half of his revenue comes from online sales; the other half is a mix of in-store transactions and pop-up sales he does in busy locations like downtown Boston. “I go where the customers are,” he told me. But his Greenfield location produces only a small part of his revenues—if he makes $50 in a day in his store, it’s a good day, he said.

$50 a day at a brick-and-mortar location? That sounds unsustainable, I wonder why even bother keeping it open? Does it help his branding/online reputation?
If it gets to that point, you need to quit, because the alternatives are quite clearly headed in a get-fired or do-something-unethical or get-burned direction anyway. Just accepting it remaining verbal is only a temporary option while you're on your way to other options.

Canadian resident here. Our kids go to daycare, it's not subsidized and costs us $1200 per month per kid (and we had a good deal). Families with kids used to have some tax breaks, they were all eliminated a couple years ago. There's some support though, you need to be really poor to get max ~$500/mo per child.

Even with my relatively good IT salary having kids here is not fun at all.
Patreon is another walled garden that can become much worse than Facebook if left in isolation. For the investors behind it it would be great, but I don't believe Patreon was a YC company? Which means its a huge untapped industry with only one major player that has consistently moved towards pulling creatives into their ecosystem and keeping them there while trying to increase revenues.

We need, probably more than in any other use case besides general social media, a federated solution to patronage. We cannot let Facebook et al happen again with crowdfunding and recurrent subscription services like Patreon. The kickstarter space has opened up to several options including the original Kickstarer, Indiegogo, GoFundMe, Fig, etc. That is a healthy competitive ecosystem and Kickstarter went public benefit so their general dominance in the market is less dangerous for it.

Patreon sits alone, and has been growing exponentially for years. They acquired their only ever major competitor, Subbable, in early 2015. Kofi is about as close to a competitor as they have, but its not the same thing in the slightest because its not automatic which is a fundamental part of what makes Patreon work.

The mindshare of creators Patreon has acquired should be terrifying to anyone who can see the writing on the wall about how this will just lead to a hegemony of Patreon controlling all the amateur and hobbyist and even some semi-professional small creative / online business ventures. And unlike most companies their revenue is plastered right in their face - all they need is a breakout moment into popular culture, which they really have not had yet - the number of people actively supporting anyone else on Patreon is still a small percentage of the whole Internet user population - but if they got that consumer breakout moment they would be unstoppable and way more directly dangerous and harmful in how many people are now making careers out of having a Patreon.

Play Music's apps are very immature and half-baked feeling compared to the alternatives.

Apple is better in that regard, but its app distribution is massively limited compared to Spotify or even Google Play.
I think you've missed this one - the typical long-haul truck driver drives somewhere far enough away that they can't return home and must stay overnight (sometimes sleeping in their trucks) before they can drive again.

This system seems to indicate that the automated trucks do the long hauls between cities and the human drivers do the shorter hauls within/around cities.

If that's the case, this is a good thing.
Completely unrelated, but do you know what happened to the old GU irc channel? I have no idea where to find it nowadays (or if it still exists).
Ultimately you're talking about breaking up two people who have probably lived together for some time and working out a sharing agreement with two people who don't really want to be around each other anymore. It's hard to imagine a scenario where there isn't friction or hurt feelings in this case.

Best case scenario the couple wasn't married very long and doesn't have much in the way of joint possessions and no kids and they both work so you don't have alimony concerns you still need to decide who has to move out.
That's in the article linked.
I am not sure that I want a company that is most famous for breaking rules, skirting regulation, and stealing medical records of it's victims operating large freight trucks on public roads.
Abundance of highly skilled engineers willing to work for low rates make a perfect setting for large consulting (and others) companies in Lisbon (and probably other cities mentioned in the article).

Yes, the city is beautiful but don't expect high paying jobs. I know a couple of YC-backed startups in Lisbon that get away with paying their software engineers around 24-30K euros per year (post-tax).

I also see another extension for Apple called Unobstruct.

> there's no way I'm going to have saved enough money to live off of

It is possible. It will take work and change on your part. The first step is to track your spending. The easiest way to do this is get an account with mint, ynab (you need a budget), or personal capital. You can link all of your accounts with the site and app. You can then categorized your spending. After you do this you can start seeing where you can reduce your spending. The major areas you can save on are housing, transportation, food, and miscellaneous. The reverse order is probably the easiest to reduce costs.

The Millionaire Next Door is a great book that talks about the difference in mindset between people who are able to build wealth well and those who are not able to. It is really eye opening if you are always broke.
They didn't replace “reservations” with “reserve bookings”, but with “Reserve bookings”; unfortunately, title case obliterates the distinction.
Ultimately, if you're a business that isn't providing what people want at a price they're willing to pay, you're not going to stay in business. I don't know that there is anything to fix here, other than making sure that the people that depend on places like this for work get a soft landing and help finding new work.
Notice that you can extend this model to passengers and long-haul bus, train, or simply self-driven vehicle transport, in all of which cases Uber is well positioned.

As a bonus, it keeps my home screen free of almost any icons...

Again, there is no proof, only hypothesis. This is in stark contrast with actual biological pathologies which have proven genetic causes, such as sickle cell anemia.

Not including externalities--such as road maintenance--distorts the market. Better to capture them all so that different forms of transportation can compete "fairly". That is, without hidden subsidies.

Strange, I feel like it's the opposite.

I, as a childless adult, couldn't care less how my friend raises her kid, just as long as she isn't abusive. It's probably because I haven't spent any time learning the ins-and-outs about raising a child, so I don't have a strong opinion either way.

But if anything, my friend has felt internal pressure on decisions she makes with her child via the opinions of other parents. This is especially true to her with respects to the pressures to breastfeed.
lot of people in this thread are patriotic Brazilians I anticipate a lot of downvotes

Anyone else find over-the-top portrayal of patriotism annoying? Every time there is someone on the TV talking about "hard working and patriotic" (I don't even have a TV, only catch a glimpse at dunkin donuts and such) even when the topic on hand has nothing to do with hard work or patriotism. You are making a very valid point, but you literally had to start your comment saying you anticipate downvotes. It has become that bad.
When something is a problem, you should shine more light on it, not avoid talking about it because it "isn't a surprise".

The general public has a short memory for this kind of thing, and no, not everyone is aware of the trade-off they're making with these services, or the true extent of the surveillance and manipulation they're submitting themselves to.

Much of society is just finally beginning to wake up to the dangers these companies present. Now is not the time to go silent about the issue. Quite the opposite.
