> [...] fraud on a debit card hits your account balance immediately, even if you can later argue to have it credited. Fraud on a credit card simply hits the credit card and can't touch your real money.

It can touch your real credit score (if not resolved in your favor), which directly correlates with your ability to continue using credit cards.

And either way, you lose liquidity until the provisional credit (which is very soon in both scenarios, also required by law!), although admittedly money in a checking account is slightly more liquid since you can pay rent and cash-only expenses with it without incurring interest changes.

> I'm always very puzzled as why in the US one would ever use a debit card

Many people don't have credit, don't feel comfortable with the possibility of having to pay absurd interest rates in case they can't make a payment, or a combination thereof.
> Unlike CUDA, there's no capable API that works on the whole range

Microsoft's D3D is very capable, and vendor-agnostic, same code works on all GPUs because the user-mode half of the GPU driver includes a JIT compiler for these shaders.

Not sure why it's not popular outside of game development. IMO their GPGPU API is the best one currently available.
Tipping for service is a little different than the tipping thats been getting out of control imo. Places are signing up for these square readers and whatever else is sold to small businesses to scan a credit card, and the default settings seem to be to add a tip. These would be jobs where the worker would never expect a tip normally, maybe a tip jar with a buck or two in it a shift if that. Plus you are expected to tip before you even get whatever service when you do it at point of sale like this, unlike the traditional restaurant approach where you tip at the very end of the meal even after you've closed out the rest of the bill.
You have a preferred theory already, and you're trying to fit the facts to it.

Unwise.
No, houses are held up to the code that applied when they were built, because those codes were generally accepted as safe at the time.

Old houses are held up to the new code when they are renovated, because updating old houses to the new code frequently requires rebuilding substantial portions of the house to comply with new requirements. It's not about "fuck everyone else." It's about recognizing that the extensive work that would be required to comply with substantially safer modern codes is best done when substantial construction work is already planned to be performed.

Commercial buildings are held to up to new codes whenever ownership, or tenancy, changes hands.

Yep! I was very inspired by Grape’s param system.
I started making Browse AI (https://browse.ai) about 3 years ago. Quit my job soon after and focused on it full-time when I had savings enough for 2 years of my living expenses.

The next 1.5 years were intense. I learned to have better and more conversations with users (we'd crash and burn if I hadn't come across a book called The Mom Test) and we went through several positioning pivots.

As I was running out of money, I launched on ProductHunt and got decent initial traction and a group of angels who found us there and invested ~$300k.

Then we started making revenue...
Then, after almost 3 years of work, we reached $100k ARR...
Then we went from $100k to $200k ARR in less than 3 months!

We've signed up ~20,000 new users in January so far and I'm projecting $300k ARR in a month! We're growing ARR 30-50% month over month.

I have a team now who are doing a ton of the hard work. I still have to spend time on every part of the business, but I've been trying to focus my energy on certain parts that I'm better at.

The hardest challenge for me throughout these years has been figuring out if I should persist and work harder on the same path, or switch to something else or pivot. I went through a pre-accelerator program and an accelerator and I had some mentors through them. Some were super helpful and gave me the confidence I needed to keep going.

In general, specially if you're a solo (technical) founder like me, I recommend having mentors that have been through what you're going through and talking to them at least once a month. It's too easy to focus on the wrong things and waste the precious early capital and time. I know I would be 2 years ahead if I had sought mentorship early on.

The plummeting rates of smoking in the US is one of the rare areas where this country really shines when it comes to social welfare. Even many European states that have what I'd consider much more progressive social welfare systems have smoking rates that are appalling, often 3x or more the US rates.
I absolutely do not use these services unless there's a substantial coupon involved, it's madness. You get a delivery surcharge, a service surcharge, and a 20% tip to top it all or risk the food be messed with. Last order was 25 eur food and 20 eur charges for two hamburger before I went in and reduced the tip %. If it weren't for the 15e coupon I'd never have completed such a predatory transaction.

I assume some of this comes from small businesses getting a Square terminal and thinking "Tips? Yeah sure, I'll check that box, can't hurt!". It can hurt. If I'm prompted to tip [15/20/25]% just because somebody grabbed a donut out of the rack and dumped it in a paper bag, I think less of the place and I'm less likely to come back.

Thought: Somebody should cook up an "AR" app that reads a menu and adds 20% tip plus local sales tax to every price. I'm just as guilty as anybody of visiting e.g. European countries and thinking everything's expensive, but that's because the prices on the menu are exactly what you'll pay, not 70% of what you'll actually pay.

Yes I realize I can just do basic mental math, but not everybody can do it, and it'd be kinda neat to point my phone at a menu and see all the prices instantly reflect what I'll actually have to shell out.
When I pay for a meal in Japan (often times with better, fresher ingredients, and prepared with more care) I pay for the meal and the service without a tip. It is the norm all over the world.

What makes the US so special that we have to provide charity on top of the price of the meal.
How many of these “machine does something humans do” articles are we going to get? It says a lot about how we’ve discovered core concepts and streamlined learning that a machine can pass a test.

My assessment is that if even people at that level of wealth and success can get addicted to opioids and die, pretty much anyone can.

Addiction, whether alcohol, drugs, cigarettes, etc., is something that is a genuine medical issue needing treatment. Thankfully, the medical community seems to be shaking off the social stigma about addiction and treating it properly now, but progress has been very slow.
Tips is a way to advertise false price, attract more customers, and then exploit their guilt to charge the full price. It's telling that food service businesses arent viable without this sort of lying.
Ok then I would agree buying a house is easy. A real-estate agent should take care of everything and you are only really responsible for stamping your seal (about 100 times) and transfering the money.

Getting a loan is also fairly easy provided you are employed and have permanent residency (or a spouse who is a permanent resident or citizen). Shinsei Bank (recently acquired by SBI) seems to specialize in loaning to foreigners.

Neighbor situation is highly variable. I have some neighbors who I am quite friendly with, and others I literally have never seen. Typically neigbors will at least be polite, but you do hear horror stories of neighbors quarreling about taking out the trash, snow falling from the roof onto the neighbor's property, etc. My next-door neighbors live with their aging parents, and the grandfather (who has dementia) once shouted at someone who was doing work on my house. And people do tend to gossip, but it's mostly harmless.

Yeah, the thing I'm most often paying for that I would tip for is my 12oz double-shot Americano. Usually between $2-$4, but I feel stingy giving the servers quarters, so it's always $1 tip.
As has been explained repeatedly, you're not providing charity; you are sharing some of the restaurant's labor cost. When you refuse to tip, you aren't withholding charity; you're refusing payment.

Why does Japan do this differently? Japan is a different place.
fentanyl is a relatively exotic pharmaceutical and is not widely prescribed except in very serious or unusual circumstances. i have read a good deal about production shifting from china to mexico in the last few years with china shifting more toward precursors following a ccp crackdown, but what i've read today suggests that the bulk is still produced and finished in china for export, with india's chemical industry as a potential major new source. i found this collection enlightening: https://insightcrime.org/investigations/mexico-deadly-rise-f...

i have very strong certainty that illicit fentanyl production outweighs legitimate simply due to the fact that it is not widely prescribed while it is crowding out the entire hard drug market in the US, but illicit fent still appears to mostly be produced by china for now.

I have been living in the US for years, but I am not from the US.

Over the past two years, I have greatly reduced the purchase of coffee and the like in coffee shops and the times when I eat outside because I am turned off by the tipping and the murkiness of the final price. When I see $10 as the price of the item I am buying, I expect it to be the final price. Instead, surprise! I have to add taxes, tips, and the cost of the air I breathe.

On the one hand, I don't want to be "culturally inconsiderate" and not tip; on the other hand, I don't have the same bovine acceptance toward money and spending issues that unfortunately many Americans seem to have -- see, for example, health care spending. I have therefore decided not to contribute to something that makes me uncomfortable. I wish many more people would say no.
Seems like all this trouble and risk could have been avoided by simply leaving a note on the car with a warning about cameras/police. That's going to discourage most people who think they are 'getting away with it' to stop.

> For sit down restaurants, or many service oriented jobs it makes for a better customer experience.

In my personal experience, it makes it worse. They annoy me with attempts to be ingratiating. They fish for tips with forms and devices which creates awkward and unpleasant situations, especially if I didn't like the service. There is nothing pleasant for me about having someone watching me and trying to guess when I want something. I know when I want something and I am perfectly capable of telling them when that moment comes.

> You ought to try sitting down in a restaurant in the EU. They do the bare minimum to serve you.

I live in the EU and I find the service at restaurants a hundred times better here. Nobody is pestering me, nobody is insulting both of us by pretending to be my new best friend. They stay out of my way until I ask for something.

SAME! I was cleaning out an old laptop I found at my parent's house last month so it could be recycled (truly too old for anyone to do anything with and not unique enough to keep around as something for nostalgia) and after waiting an eternity for the slow as fuck HDD to spin to life, I was greeted by Windows XP and a bunch of memories, including DaemonTools and other ISO/cloning stuff. Truly took me back in time to high school.

I do not know why I needed this stuff on my mom's laptop, but I assume I was either installing pirated software on her machine (honestly, that is the most likely reason) or I was trying to troubleshoot stuff and her CD/ DVD drive wasn’t working for some reason. One thing is for certain, she did not put it there! I made her move to a Mac in 2009 or 2010 before I would do any more computer repair for her, so it was truly a blast from the past.

(Unrelated aside, my father refuses to use a Mac and if I gave him a Linux laptop, he’d literally just go buy something overpriced and covered in adware at Best Buy and get scammed into some antivirus subscription, so I begrudgingly had to start agreeing to service his laptop again after he fell for a ransomware scam the second time, not to mention the fact that I got a job at Microsoft sort of made my “no Windows tech support” rule feel wrong (even tho I worked on Linux at Microsoft and had a corporate-issued Mac.) Thankfully, Windows is much easier for me to deal with these days and I’ve set up his machine so I can ssh into it remotely if I have to. )

The airplane takes off if, on average, the sum of dollars that all ticketed passengers are willing to pay for the benefit of being on it is larger than the operational and capital cost of the airline for operating that one flight.

It's tough to portray just how ubiquitous smoking was to a modern audience. You would go to a restaurant and the first thing your hostess would ask is "smoking or non"? I remember standing in a checkout line in the 80s as a child and being fascinated with the billowing clouds of smoke an old lady blew. I remember coming home from bars reeking of smoke, even though I didn't. Even teachers had their own lounges that reeked of smoke (nowadays in some states you could be fined for possessing Tobacco products on school grounds!).

I often think about how much younger today's generation looks and I can't help but think it's due to the huge reduction in the amount of people who smoke. The people I grew up with who still smoke look 5-10 years older than their peers.

As a tourist it sucks though. You have to buy something to see the various taxes, then hope that they're the same for everything. Then you move on in your trip and have to repeat the process.

Just advertise the actual price, dammit.

And keep tipping for "OMG, this person was wonderful" not "this is 90% of their income".

> you tip. generously

No, absolutely not, that is not the correct solution to the very real problem of underpaid staff.

Instead I want laws to ban tipping and force jobs to pay a reasonable living wage at a minimum. Yes the product will cost more in restaurants but so be it, it's the honest way to do it.
> It costs time, effort, and money to provide better service, so I'm not from where you get the moral dimension of having to buy them. They have a cost; of course you have to buy them.

It's an odd industry where you perform a service, then hope your customer decides to pay you for it.
Interesting, thank you for the context. My company's current system is simpler in nature I think (three web servers processing internal and external requests, one DB server, one app server handling everything else, and that's our problem) and scales not at all. We're going from one monolith to another, but set up in a way that can be scaled out arbitrarily, and overall more flexible and robust.

Generally I'm interested in stories of these big do-overs because it hasn't been the smoothest of sailing for us.

The thing that annoys me about spotify is the order does not seem to work. I was listening to some beach boys songs, then went to play an album by marvin gaye. It played the first song in the album, then went and started playing beach boys songs again. This just started happening this week, never had the problem before. Another problem was podcasts were either missing episodes or playing out of order.
That doesn't seem unreasonable. I don't think I've ordered delivery in like the last 2 years (when someone else was ordering and I got something).

Japanese people are culturally more inclined to be pleasant, it's part of the way they're raised, so I don't think that's a good example.

I've not had a pleasant experience in most other western nations. I won't say it was bad but it's nowhere near as efficient and you have to really get waiters attention before they'll do anything.
