>Agreed. Even xAI's (Grok's) access to live data on x.com and millions of live video inputs from Tesla is a moat not enjoyed by OpenAI.

Tesla does not have live video feed from (every) Tesla car.


> Fines should be designed to make it uneconomical to continue to reoffend.

Great. Fine me $1 million, and I will fight the case with lawyers, thus slowing down the public legal system for thousands of other legal cases, whether traffic related or otherwise.


IDK why this is downvoted. In practice everything is this way. Anything over a few grand is basically an invitation to lawyer up and fight. Whether it's a traffic fine or some local zoning BS this is always how it goes.

And by "IDK" I mean "I have some suspicions but they're not flattering to the community".


High definition cameras are cheap, I don’t see why these “fights” would be costly.

>I don’t see why these “fights” would be costly.

Most of society doesn't share most of HN's pro-jackboot disposition so there'd be warnings, appeals, etc, etc.

As a comparison point, it took a 20yr frog boiling exercise to turn DUI into a huge state revenue stream and that's at least backed by a crime most people can agree is fairly serious. To get the same for less serious crime you'd need to invest even more up front in propaganda because people aren't dropping dead from road infractions today like they were 40+yr ago so your ability to appeal to emotion is even more limited.

We can't even release the Epstein files. We don't go full jackboot on petty crimes with a victim. To think that there's public apetite to ruinously fine motorists out of large sums of money over petty victimless infractions is Luxury Space Communism (TM) type tone deaf lunacy.

And this is all assuming you get a bunch of friendly judges because this stuff is pushing it in terms of what the 6/7/8/14th amendments will tolerate.

Like FFS, get out of your filter bubble people.


> The term for that is false advertising.

No different than Elon Musk claiming self-driving will be deployed to all Teslas in 2017; 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026.


> I so much hate it that we have built an economy where companies believe the best way forward is to cram ads into everything instead of building better products.

Blame the consumers.

They don’t want to pay for monthly subscriptions because “economy is tough”


Or maybe companies turned products that were one-time purchases into monthly subscriptions. Or companies made it incredibly hard to cancel monthly subscriptions. Or companies will continue to charge and auto-renew us even when we clearly don't use the product. Or companies will unilaterally degrade our service or push us to lower tiers in order to better serve customers who aren't you. Or companies will have us pay a monthly subscription, and then also sell our data to the highest bidder anyway.

Maybe many of these companies have never had our interest at heart, and people are tired of feeling constantly screwed over and seen as a revenue stream instead of customers.


It's an unstable equilibrium: companies can always make more by adding ads, therefore they do so. This isn't the consumer's fault.


> Blame the consumers.

The consumer is not a single person, and until we (the consumers) all coordinate, our individual incentive is to not pay (Classical prisoner dilemma).

So "voting with your wallet" doesn't maximize your personal interest.


but we _were_ paying for monthly subscriptions to prime vide.


> They are also tied for first for having the highest cost of living.

Who cares?

Absolute savings rate and net worth are what matter.

Any European will gladly live in America for US$1 million/year income even if the cost of living is US$300k/year.


Americans at every wealth level live shorter lives than e.g. Brits.

> Absolute savings rate and net worth are what matter.

OK, now tell me how the savings and net worth look like for your average American. I'll give you a bit of a spoiler: it's not good.


Who the fuck do you know that makes a million dollars a year? The majority of Americans barely clear that bar over their entire career.


> Being pompous and self obsessed requires none of those things.

Sufficient, but not necessary


> The next step forward has been to stop moving scooters to power and instead bring power closer to where vehicles operate.

Asia already has swappable batteries not just for bikes and scooters, but also motorcycles and even some cars.

This is in addition to slow-charging bike stations (similar to CitiBike in NYC) and scooter parking with wireless charging.


> You just made sure only people who can afford to live near work are hired.

And what’s wrong with that?

Is every person on earth entitled to a job?

If yes, voice your concern with your local government.


This take feels like it’s being made in bad faith.

Person 1 - childless, has a flat in the city.

Person 2 - couple kids, needs more space, lives 45 minutes from work

Why should person 2 be at a disadvantage?


> I've always assumed peer review is similar to diff review. Where I'm willing to sign my name onto the work of others. If I approve a diff/pr and it takes down prod. It's just as much my fault, no?

No.

Modern peer review is “how can I do minimum possible work so I can write ‘ICLR Reviewer 2025’ on my personal website”


The vast majority of people I see do not even mention who they review for in CVs etc. It is usually more akin to a volunteer based, thankless work. Unless you are an editor or sth in a journal, what you review for does not count much for anything.


> No. [...] how can I do minimum possible work

I don't know, I still think this describes most of the reviews I've seen

I just hope most devs that do this know better than to admit to it.


>but for various reasons can end up flopping when actually executed in the real market.

1. Your order can legally be “front run” by the lead or designated market maker who receives priority trade matching, bypassing the normal FIFO queue. Not all exchanges do this.

2. Market impact. Other participants will cancel their order, or increase their order size, based on your new order. And yes, the algos do care about your little 1 lot order.

Also if you improve the price (“fill the gap”), your single 1 qty order can cause 100 other people to follow you. This does not happen in paper trading.

Dear HFT Quant,

> And yes, the algos do care about your little 1 lot order.

I'm just your usual "corrupted nerd" geek with some mathematics and computer security background interests - 2 questions if I may 1. what's like the most interesting paper you have read recently or unrelated thing you are interested in at the moment? 2. " And yes, the algos do care about your little 1 lot order." How would one see this effect you mentioned - like it seems wildly anomalous, how would go about finding this effect assuming maximum mental venturesomeness, a tiny $100 and too much time?


Retail speculator here. Re 2 it's often quite easy to demo on thinly traded markets - I'm more familiar with crypto. Say the spread is 81.00 buy, 81.03 sell. Put in a limit buy at 81.00 and watch someone/something immediately outbid you ate 81.01. In the short term that kind of thing is done by algorithms but there are humans behind it and doing it too.

There's quite a lot of other game playing going on also.


if you are targeting such "scales" you are highly speculative, that is something like 0.0xx% :-D Can you sleep well with this? :-))


Even a 1 lot order could be the deciding factor for some algorithm that's calculating averages or other statistics. Especially for options books.


Sometimes the spread is really tight.


If you actually were in the industry, you would know that most retail traders don't fail, because they lose a tick here or there on execution, they fail, because their strategies have no edge in the first place.


> If you actually were in the industry, you would know that most retail traders don't fail, because they lose a tick here or there on execution

Where did I say “retail trader”?

Because “institutional” low-latency market makers trade 1 lot all the time.


The context from parent was obviously that. Instis don't trade on Alpaca.

> Because “institutional” low-latency market makers trade 1 lot all the time.

That sentence alone tells me that you're a LARPer.


> That sentence alone tells me that you're a LARPer

cope.

Equity options are sparse and have 1 order of 1 lot/qty per price. But usually empty. Too many prices and expiration dates.

US treasury bond cash futures (BrokerTec) are almost always 1 lot orders. Multiple orders per level though.

I could go on, but I’m busy as our team of 4’s algos are printing US$500k/hour today.


There is a big difference between back testing scalping and back testing buy 100 NVIDA at $103 and sell at $110.


>Your order can legally be “front run” by the lead or designated market maker who receives priority trade matching, bypassing the normal FIFO queue. Not all exchanges do this.

Unless you're thinking of some obscure exchange in a tiny market, this is just untrue in the U.S., Europe, Canada, and APAC. There are no exchanges where market makers get any kind of priority to bypass the FIFO queue.


Anyone can be a market maker on a trade just take the other side of an offer. All they really do is make a market with you and then make a market with the other side and pocket the change. It's good for market liquidity.


> There are no exchanges where market makers get any kind of priority to bypass the FIFO queue.

Nope, several large, active, and liquid markets in the US.

Legally it’s not named “bypass the FIFO queue”. That would be dumb.

In practice, it goes by politically correct names such as “designated market maker fill” or “institutional order prioritization” or “leveling round”.


I can tell you as someone who is a designated market maker on several ETFs in the U.S., none of this exists as a means of giving market makers priority fills. You're taking existing terms and misusing them. For example institutional order prioritization is used as a wash trade prevention mechanism, not as a way for designated market makers to get some kind of fill preference. Leveling rounds also do not involve exchanges, this is an internal tool used by a broker's OMS to rebalance residuals so accounts end up with the intended allocation, or cleaning up odd-lot/mixed-lot leftovers.

I am getting the feeling you either are not actually a quant, or you were a quant and just misheard and confused a lot of things together, but one thing is for sure... your claim that market makers get some kind of priority fills is factually incorrect.
