SirSourdough··on Nothing Ever Happens: Polymarket bot that always buys No on non-sports markets
It doesn't seem like it's strictly true that they don't charge trading fees.

From their docs, it looks like they charge fees to bet "takers" (as opposed to makers), but exclude the geopolitical and world-events markets where they don't charge fees.

I have to imagine that may be related to some of the blow-back towards prediction markets about profiting on topics like war & their potential for manipulation.

Given it sounds like the bot bets everywhere other than sports, many of those categories would likely have fees in this case.

SirSourdough··on Show HN: I built a word game. My mom thinks it's great. What do you think?
For those of you who are put off from trying the game by the category for today’s puzzle being sports, note there are other puzzles from prior days with more general topics.

SirSourdough··on Ask HN: How to Become a Billionare?
I don’t think the implication was that everyone can be a billionaire with luck - rather that virtually nobody becomes a self-made billionaire without some (and often a lot of) luck.
SirSourdough··on Ask HN: How to Become a Billionare?
I think this makes the economic circumstances which allow for a billion dollar company to be created sound rarer than they are.

There have been numerous technologies that have emerged or hit the mainstream in my adult life that have spawned multiple billion dollar companies. EVs/charging, renewables, crypto/fintech, much of “modern” social media, same day/last mile delivery, drones, etc. Probably at least a few that I don’t know exist. Looking back across the history of business and innovation in the 1900s, this doesn’t seem that anomalous.

I think the actionable framing of this is -

- Build skills that are transferable between different industries that allow you to take advantage of the areas of greatest opportunity as they emerge.

- Build a network of likeminded people with complimentary skills who are willing to take a flyer on opportunities with you.

- Make friends with people with money who will fund these efforts, or build a resume that will make you an appealing founder or very, very early employee to VCs.

I do think that the situation of your birth has a major impact on your ability to put yourself in this position - I’m less sure about the timing aspect.

SirSourdough··on Donating forks to the dining hall
Yes and no. If consuming the lanes as much as possible was the goal, we’d be parked bumper to bumper with no available space to move at all.

We want the throughput of the road to be as high as possible. Broadly, that means maintaining the optimal (minimum) spacing to make the merge safely without changing speed, while maximizing speed.

You may get larger areas where speeds are disrupted, but on the average be going faster. Stop-and-go traffic introduces tons of inefficiencies since drivers need to be much more cautious than in a consistent traffic flow.

The big challenge is that it’s basically impossible to know what the optimal speed is, since it relies on knowing the detailed state of the road and traffic volume miles ahead of what you can see.

Self-driving cars are interesting here since they will open up new opportunities for all the vehicles on the road to co-regulate their speed near to the optimum.

SirSourdough··on How many EV charging stations does the US need to replace gas stations?
As others mention it really depends on your use case.

If you can charge at home (ideally at 240v), and you don’t drive more than the range of your vehicle in a day regularly, it’s gas that has an inconvenience to overcome. I don’t have a gas pump at my house.

If you are an Uber driver and you do 2-3x the range every day, it’s a different story. But if you can charge for free - which isn’t hugely uncommon currently - you can save a lot of money on gas with an EV, so there are tradeoffs.

SirSourdough··on Tesla conducting more layoffs, including entire Supercharger team
Deep integration with the car is the most difficult piece of the Supercharger system to achieve for any other charging network. They have the best in-car and in-app charging experience, with the best routing to chargers and scheduling tools. Most networks still require you to use an app or RFID card to start a charge, Tesla you just plug in.

The other is probably just scale of the parent company in terms of being able to build out and service the network. They tend to have more prominent, nicer locations for their stations.

SirSourdough··on Autonomous Overhead Powerline Recharging for Uninterrupted Drone Operations [video]
If the drones could meter their own consumption from the line using a utility-approved meter, anyone with a drone with said meter should be able to just tap onto lines at will and get a bill at the end of the month.

Not sure how that plays out in terms of the weight/packaging of the drone but seems feasible for at least larger drones.

SirSourdough··on Stability.ai – Introducing Stable Video 3D
Hypothetically, sure, assuming the parent comment that these meshes are sufficient for modelling is correct and that you can find any teens who want a non-digital toy.

I think a good hobbyist application for this would be something like modelling figurines for games, which is already a pretty popular 3D printing application. This would allow people with limited modelling skills to bring fantastical, unique characters to life “easily”.

SirSourdough··on Toyota's hybrid-first strategy is delivering big profits
My dad handed me down our 2001 4Runner when I got my license and it was a great first car as a high school and college kid.

Not enough performance to be that tempting to do anything dumb, tons of space for friends and stuff, go anywhere, sleep in it, easy to maintain… Bumpers were rusted to hell but it had a sunroof and you could roll the rear window down so we were having a great time!

SirSourdough··on Americas richest 10% is responsible for 40% of its planet heating pollution
I don’t think the argument being made is that the cost should be proportionate to wealth, but proportionate to impact or alternatives.

If flying private incurs 10x or 100x the externality costs of flying coach, it should be priced (taxed really) to reflect that a significant portion of those externality costs are an unnecessary luxury benefit.

SirSourdough··on Submarine expert tried to dissuade OceanGate CEO, from taking customers in Titan
I believe it’s both really. My understanding is the end caps are bolted to a titanium flange, not the carbon fibre hull directly. The titanium flange the caps are bolted to is epoxied to the hull.
SirSourdough··on Submarine expert tried to dissuade OceanGate CEO, from taking customers in Titan
I’m sure it’s not the case that any random person can get a quote for something like this, but in the case of Titan the people who can afford the $250k ticket probably can.
SirSourdough··on Debris found came from missing Titan sub, says friend of passengers
I saw a bit of video where they showed the construction- it’s a few inch wide band of carbon fibre wrapped around an inner tube like a spool of thread until it reaches 5” thickness.
SirSourdough··on Developer tools to create spatial experiences for Apple Vision Pro
I don't really understand this assessment. Half as much is $1,750. That's really not much compared to what people are willing to pay for Apple devices. Basically the price point of an iPad Pro, and I think the potential of the Vision Pros is much higher than the potential of the iPad. It's just a matter of whether they can realize some commercial use-cases like with the iPad.

The Vision Pro is marketed as a device with the potential to replace or significantly augment a laptop and/or TV for a lot of users (I understand there are presently some asterisks needed there). And that's assuming no other novel, high value uses emerge.

Apple sells something like 7 million MacBooks per quarter. Many of them are well more than $2000. I don't think a $2,000 price point is a crazy barrier if the device is able to live up to what it could be.

SirSourdough··on Developer tools to create spatial experiences for Apple Vision Pro
This is also done in auto racing, particularly endurance racing where you might pick up 4+ hours of bugs and debris on the windshield over a driver stint.

The windshield has a stack of huge stickers on it that get torn away by the pit crew during stops. Apparently you can get stacks up to about 20 layers.

Seems like a reasonable possibility for messy AR applications.

SirSourdough··on Reddit is removing moderators that protest by taking their communities private
I believe this is more than speculation. Pretty sure that someone from Reddit basically said as much in one of the transcripts or conversations shared by Apollo’s dev. Reddit feels they are getting burned by letting their data be used to train LLMs for free.

That said, they were also letting people exceed their API rate limits by massive amounts, so hard for me to put the blame anywhere but with Reddit.

SirSourdough··on Reddit is removing moderators that protest by taking their communities private
Is this supposed to be some kind of takedown? Why would I care that one of the moderators of a subreddit has a normal, common occupation?

That article is so petty it deserves no one’s time.

SirSourdough··on Reddit subs with millions of followers plan to extend the blackout indefinitely
If one of Reddits big goals in all this is to sell actually useful information on a broad variety of topics for training LLMs (I think they’ve basically said as much), then I’m not sure that only being able to prop up a few meme and cute animal subreddits is that much of a win.

It’s the long tail of niche subreddits where almost all the content that keeps Reddit at the top of SEO rankings and makes them interesting for training AI lives.

SirSourdough··on Reddit subs with millions of followers plan to extend the blackout indefinitely
Reddit forcing open the subreddits would result in massive backlash from moderators, who are often the main people providing content and enforcing content quality. It would crank the degree to which Reddit is tarnishing its reputation to 11.

A very small portion of users are responsible for the majority of the content and community building on Reddit. I think you might be underestimating how reliant the 99% of users who don’t post top-level content or serve as moderators are on the 1% who do.

SirSourdough··on Mercedes-Benz to introduce acceleration subscription fee
All of that can be accomplished with one-time purchases. What’s the value-add of a subscription?

It’s great that future buyers can upgrade, I think that’s cool. But now sellers can’t recoup any of the money they spend on these features, and over the life of the car they are likely to cost many times more. It’s brutal for lower-income people relying on decent cars to eventually reach a price point they can afford, because they’ll need to effectively pay for every option like they are buying new.

SirSourdough··on Mercedes-Benz to introduce acceleration subscription fee
I wouldn’t complain if it was a one-time purchase. Different spec levels have always cost different amounts for basically every product.

But what ongoing value do I get for my subscription? Will I get free acceleration upgrades over time because they keep improving the software? Free brake light DLCs that show how hard I’m accelerating? It’s great I can upgrade OTA but what about that means I need to pay over and over?

Acceleration is not a service- there’s no ongoing cost to deliver it to owners and there’s no increase in value to the owner over time to compensate for the ever increasing cost. That’s why I think the subscription model is much more exploitative.

SirSourdough··on Bankman-Fried being invited to speak at a New York Times event alongside Yellen
Sure, as long as your emotions are driven only by the contracts you sign.

People sign a waiver accepting the risk when they go whitewater rafting, but that doesn’t stop it from being a potentially life-altering traumatic experience for a rafting guide when a kid falls out and drowns under the raft.

Likewise, if you care about your client’s financial well-being as a wealth advisor, and you make a choice that destroys years of your client’s savings, retirement, etc. it would be understandable to feel distraught about that.

SirSourdough··on CEO pay skyrocketed 1,460% since 1978: CEOs paid 399 times as much vs. worker
If this money was distributed among the wealthiest 10% it would be far more distributed than it is now.

Most of the people driving the 399x compensation figure are in the top fraction of a percent for wealth, and even small-time CEOs are mostly well above 90th percentile earners.

SirSourdough··on CEO pay skyrocketed 1,460% since 1978: CEOs paid 399 times as much vs. worker
I don’t think there’s all that much concern about incentive packages tied to performance.

The question in my mind is: how much compensation is required to provide that incentive? And is it reasonable for that to result in a small portion of people making not just more than the typical person, but astronomically more to the point where the typical person is left very nearly broke and powerless?

SirSourdough··on Welcome to Hell, Elon
Although I think it’s always kind to be polite and constructive with feedback, I totally disagree that you have to be as capable a cook as the chef to critique their food.

You don’t have to be a culinary wizard to tell when many foods are overcooked, underseasoned, etc. Sometimes chefs just screw up and a dish has outright unpleasant qualities.

Most people have hundreds or thousands of points of comparison for high-quality food even if they can’t make it themselves. If a restaurant bills itself as high-quality and then doesn’t live up to that standard I think it’s perfectly reasonable to say so.

Is peer review more valuable? Probably. But most restaurant guests aren’t chefs so pleasing non-chefs is valuable too.

SirSourdough··on Hans Niemann Suing Magnus Carlsen, Chess.com, and Hikaru Nakamura
“Improving your lie” is a common way, meaning altering the environment around the player, swing path, ball, or shot path in a way that yields some advantage.

This would include things like breaking off a twig in your way, removing leaves or grass around the ball, etc.

SirSourdough··on Why is rent skyrocketing?
“Sell to the highest bidder” and “fair” rarely belong in the same thought.
SirSourdough··on Apple tells employees to work at the office three times per week starting Sept
I'd say it's a pretty rare luxury to be able to commute less than 20 mins for your entire career. There are tons of jobs that happen in major cities that don't pay enough to live within 20 minutes. Many don't pay enough to reasonably commute by car.

Plus there are a lot of life circumstances that make people accept different tradeoffs over time (schools/districts, medical care, aging/ailing relatives, space vs price, urban vs natural, car vs transit etc).

SirSourdough··on Build your own EV charging solution
My impression is that car manufacturers have just been slow to roll it out, and that the implementations aren’t that standardized so there’s another layer of adoption by the charging networks that has to happen.

Agreed about the apps. Have you found any that you particularly like? Pretty much all of them are just map > list of chargers > start button. NFC tap or scan a QR code if it’s “fancy”. But I’ve yet to use anything I thought made charging a nice experience…
