Any of the maximize or minimize arguments are going to be simplistic and reductionist. The optimal real world strategies are always going have to account for other factors like relationships, political stability, goal alignments, power/dynamics, etc, etc. These factors will be different for each nation you're dealing with and will greatly affect what the best import/export and tariff ratios should be. And these may also change over time. The importance of these factors (different for each nation) are so strong as to overwhelm any of the economist theories about maximize/minimize.

It seems to be 10x for 80% and 20x for 100% while 100% gives 50% of the range of a gas vehicle for a full-speed level 3 charger. Level 2 chargers are another order of magnitude slower (say 8 hours). I I would like to see the wattage over time for gas to compare with.

The article

>The commission estimates that more than 162,000 chargers are Level 2, which can provide roughly 14 to 35 miles of range per hour of charging, and nearly 17,000 are considered fast chargers

No: it's a fraud be that legal or moral.

If you want a job that someone is offering and they ask you for irrational, unreasonable, or just stupid demonstrations as a prerequisite for getting hired, you have one choice: decide for yourself the show isn't worth the price of admission and walk away... or you do the irrational, unreasonable, or just stupid thing asked to the best of your ability and keep your hat in the ring for the gig. Either way honesty and ethics dictate that you either play the game or walk away.

The moment you cheat and lie: that's entirely on you and perhaps your own dumbass decision to train and enter an industry that works this way. Of course, I mean "you" in the abstract, not necessarily you personally.

> The aim would not be to protect specific manufacturing sectors or national champions but to counter the United States’ pro-consumption and antiproduction orientation. The goal of American tariffs, in other words, should be to eliminate the United States’ automatic accommodation of global trade imbalances.

Instead we got a default rate of 10%, and higher rates on (e.g.) Madagascar whose main export to the US is vanilla—which the US can't grow anyways so it's not like they they need to protect anything. Or the Falklands Islands, whose chief export is… the Patagonian toothfish. Does the US have a strategic in that? (And let's not get into the meme-worthy penguin islands.)

There are good reasons for tariffs: national security concerns, infant industry protection, national champions.

But the recent policies are not that.

It's important to also consider industrial base:

> Democratic countries’ economies are mainly set up as free market economies with redistribution, because this is what maximizes living standards in peacetime. In a free market economy, if a foreign country wants to sell you cheap cars, you let them do it, and you allocate your own productive resources to something more profitable instead. If China is willing to sell you brand-new electric vehicles for $10,000, why should you turn them down? Just make B2B SaaS and advertising platforms and chat apps, sell them for a high profit margin, and drive a Chinese car.

> Except then a war comes, and suddenly you find that B2B SaaS and advertising platforms and chat apps aren’t very useful for defending your freedoms. Oops! The right time to worry about manufacturing would have been years before the war, except you weren’t able to anticipate and prepare for the future. Manufacturing doesn’t just support war — in a very real way, it’s a war in and of itself.

Basically, you own what you control and can protect from leaving your control, by force, or punishment. The modern state is almost based around ownership and freedom, and takes the responsibility for a lot of that.

It may be immoral (not necessarily a crime, mind you) if someone deceives you, but so is using Bitcoin. You're burning the Amazon, while serving as a cash convertor for criminals. Just for personal gains.

When did you switch to pair programming? Your post starts by stating you just hired the unqualified dev last month, so did this unqualified dev slip through your pair programming system? And if they did, doesn’t that undermine your view that the pair programming approach has dramatically improved your good hire hit rate (or, if pair programming is newly instituted in response to the unqualified dev hire, how can you claim to have an improved hit rate in only one month of use)?

> If 2024 was when they crossed that threshold, that feels like a huge jump in EV chargers (almost 50%) in a single year.

EnbW last year increased their fast chargers by 66% in Germany. They are the biggest fast charger operator now in Germany and operate 6000 fast chargers [1]. I often charge there and can confirm that you can find their chargers everywhere and also that they actually work. According to the annual report, they plan to keep this growth up till 2030.

So yes 50% in California seems plausible.

"EVs convert over 77% of the electrical energy from the grid to power at the wheels. Conventional gasoline vehicles only convert about 12%–30% of the energy stored in gasoline to power at the wheels."

EV charging doesn't need to deliver anywhere near the amount of energy contained in gas to displace gas.

Much of the heat from a subway comes from the HVAC in the train. Add more venting to the trains that works with the trains movement and use forced air into the tunnels. Costs more but it can be done. Some of the heat comes from acceleration and braking. Make that more efficient with newer electric motors, better designed tracks, better regenerative braking. If that doesn't work require everyone to disrobe before leaving their underground home.

Another option would be to deprecate trains. Instead people travel through pressurized maglev modules in tubes at 800 mph / 1200 kph. Transcontinental tubes accelerate the modules to 8000 mph / 12,000 kph. Interplanetary offramps eject the module from earth at mach 50+ where it is caught by a sub-orbital robot ship that matches speed and takes the module to the interplanetary colony ship.

Yeah, of course. I’m a renter, I understand. Some states [1] have laws allowing tenants to install chargers, although obviously not all renters have designated parking spaces. Where I live (NYC), most people rent and the idea of a “tenant parking space” is fairly foreign, but there are a decent number of EV chargers on the street in my neighborhood, so people make it work.

Can we just stop doing performative technical interviews already? The only other industry that does interviews the way we do them for senior people is the performing arts and performing is right in the name.

The engineers I’ve worked with who’ve caused the most damage by far, have have been technical tornadoes who did fine in interviews.

I’ve never seen any damage caused by someone who slipped through the cracks without being able to code at all (and I’ve worked with people like that).

I think we’d be much better off if we just fired people who outright lie about their ability to code and spent more time digging into previous employment history, talking though projects, and talking to old coworkers.

On the other hand, a significant number of trips will begin their trip with a full "tank" (battery) and will therefore not even need to stop to refill.

The median distance travelled on long-distance trips is less than 200 miles in the US, which is clearly within the limit of a normal BEV battery.

Yet playing a mixed strategy means that—-to maintain unpredictability—-these deals to avoid venal retribution are not always offered.

While you're not wrong, the two sides (Trump vs Sanders) do have entirely different approaches to reforming the system. The latter would (probably) like more control over production means in the hands of laborers, and sees progressive taxes as a way to support a social state. The former wants top-down control through laissez-faire, and sees reducing taxes as a way to get rid of the state.

> the team has turned to a single satellite, NASA’s Terra, which has been monitoring the planet for nearly a quarter-century. Looking at the same cloud systems, the team found exactly the same trends, with cloud coverage falling by about 1.5% per decade, Tselioudis says. “It’s only now that the signal seems to be coming out of the noise.” Bjorn Stevens, a climate scientist at the Max Planck Institute for Meteorology, says a couple percentage points may not sound important. “But if you calculate these trends, it’s massive,” he says. “This would indicate a cloud feedback that’s off the charts.”

I don't think it's a lot of assumptions at all. You hear people decrying ad-supported websites all the time. When pressed on the issue they essentially resort to "well maybe these websites shouldn't exist then!", which isn't a solution.

You also hear a lot of Europeans cry out for censorship. They just think their kind of censorship will leave them alone. Until it doesn't. But they don't have to worry about it, since they're on American platforms anyway.

The managers are just putting that number into a spreadsheet which then gets combined with other spreadsheets and given to an upper level of management which does the same.

When I get asked for estimates I always ask what number would work best for them and then say that. You'd think I'd get a pushback on that approach, but I don't.

> Do you think Trump and the GOP are doing it because of labor rights?

Nobody knows why they are doing it, since nobody can read their minds. But I was not talking about them, I was addressing your implied argument that all tariffs are bad and abolishing them will lead to global prosperity. I would think that abolishing tariffs would at least give other countries huge incentives to exploit their own populations (including children) in order to get money from countries where such exploitation is illegal.

I guess my experience with different, because I never had to grind leetcode. I had some basic algorithmic lesson at my University (and a short adventure with competitive coding) but that's all. I never had a technical interviews where that was a problem - either there was no typical coding question, or a simple sanity check exercise. Instead we discussed some problems and thinks related to the job. I understand my experience is not typical - partially maybe I'm currently in the field of it security - but that still doesn't justify participating in the broken process with tools like this. If a company hiring process is broken just... walk away? Let them burn with leetcode grinders with no real experience that they'll finally hire.

Most people aren't buying a 1TB iPhone Pro Max - which is the model described by analysts.

Realistically, Apple will eat much of the cost, but increase prices by 10-15%. Most other retailers are thinking the same.

This was noted in the Reuters article [0] this macrumors article stole content from:

> the company will have a tough time passing on more than 5% to 10% of the cost to consumers.

> "We expect Apple to hold off on any major increases on phones until this fall when its iPhone 17 is set to launch, as it is typically how it handles planned price hikes."

Do you expect Madagascans to buy more US goods with their $600 per capita GDP income? Because Madagascar's chief export to the US is vanilla, and it got hit with 47% tariff rate.

Or the Falkland Islands' 58% rate: is the US interested in growing its own Patagonian toothfish? Because thats what the Falklands sends to the US. What do you expect the 4000 inhabitants of those islands to buy from the US?

NGO workers may not be 'mustache-twirling villains' but USAID literally is, well perhaps sans the mustache. They are actively and regularly used to destroy and/or manipulate countries while operating under the pretext of aid. Their purpose is not to help other countries, but to manipulate them.

What I'm saying about sustainability is not some outside angle. Look at most of any effective charity doing work in impoverished places and it's always about sustainability. In the most typical example you don't simply give water to people - instead you encourage, and if necessary - assist, them in building wells. Charity will eventually run out for one reason or another, and when your entire system has been built with no focus on sustainability you can create catastrophic scenarios.

And I don't really think there is some huge gap in between the parties - they both keep stooping to ever new lows in order to get one off on 'the other side' all while they are both are in almost complete harmony when it comes to corporate handouts and warmongering. As I'm sure you're aware I could list a zillion things the DNC has done, but I don't really see the point? Do we give each side -1 point for each time they screwed people over, and see who gets the lowest score.. and probably still not change our views? It's pointless.

And no, why would I be tired of reading what you're writing? What fun is there is in talking to somebody you agree with? 'Yeah man, you're so right, and so I am. Yeah... yeah.' Having a good healthy debate is far more pleasant. For instance in our little conversation you really shattered my stereotypes by stating you'd be happy with Russia or China providing support to rural areas, and that's always a fun thing!

> You’ll probably want to use the bathroom/buy a drink anyway, so charging taking four-ish times as long as pumping isn’t really a big deal.

That doesn't take nearly as long as charging, nor do I need to do it as frequently as I would need to charge. And even if it did, the places where you can do that, and the places with chargers, aren't the same.

Maybe the US will get there in a decade (or two at current rates), but for now a PHEV seems like the best of both worlds.

Really... so two "wrongs" really do make a "right".

So when an employer sees many employees and candidates work the system like this, then they are also right to say, "pretty much every employee we've hired or candidate we've spoken with tries to dishonestly game the system and deals with us in bad faith, so we're justified in screwing with them any way we please. No moral fraud here: we're just doing onto those as those would do onto us."

Well, great... you've defined a level playing field that's working as optimally as it can and without any moral blame at all.

When doing a tech interview, watch the person’s eyes. Pay attention to the pacing of their answers.

If they seem to be reading intently, that’s a flag. If their answers are fluffy and vague and then get very specific, that’s a flag.

Tools like this might not show up on shared screens, but people who use them behave unnaturally. It’s pretty obvious if you know what to look for.

I’ve been doing dozens of technical interviews per month and it’s pretty clear when the person is Googling answers or using some ai tool.

there just aren't enough doctors. nobody talks about the cap on licenses that the AMA will issue, which makes it so nobody ever has more than a few minutes with their doctor. It's to the point now where seeing an MD at all is a challenge. You go to the hospital and it's NPs and PAs as far as the eye can see.

it took my wife years to discover a chronic illness. why? every appointment is so short. how is any doctor supposed to diagnose anything so fast? disparate symptoms, patterns that are only noticeable over years, and five minute appointments

and for the record she was dismissed for years by a woman doctor and finally diagnosed by a man. anecdotes are just that.

what we need is more doctors, so we can afford to have more than a few minutes a year with them

I'd be curious to see numbers on this. Currently I believe you, although as EV adoption expands and EVs get cheaper I'd expect to see more people who can't charge at home buy them and charge at work/stores.

Also I don't have an EV, but if I did charge it equivalently to how I use my gas powered car, 1 trip to where I needed to recharge outside of the house would likely be equivalent to about 80 days of home charging.

Interesting, the area I live in is expected to get more rain as climate change gets worse. So I would think we would have more cloud cover. But the article is about "reflective clouds".

Great question — I’m using traditional OCR engines for the initial text extraction (e.g., MathPix, Google Vision), but then I apply generative AI models in a second stage to refine the output. This includes removing noisy or irrelevant elements, normalizing format inconsistencies, and improving alignment across multi-modal inputs.

In addition, for figures and diagrams, I use Gemini Pro Vision not just to extract the content, but to generate context-aware, structured descriptions that are better suited as ML training input — rather than just dumping raw image text.

So in short, generative AI is used here more as a smart post-processing layer to enhance the usability and semantic clarity of the OCR outputs.

> The primary benefit of an EV is that you ~never need to stop and “refuel” it unless you’re making a long road trip.

Maybe for some people. I bought an electric car in 2018 because I think over the long haul that, first, they'll be better for the environment and second, disentangle my country from foreign energy producers. Note: I'm not saying EVs or current battery tech are perfect in these ways now, just that I think they have better long-term potential, which will only be realized if people buy imperfect EVs today to justify investment in making them better tomorrow.

All that said, while my family has never had a problem with charging on long-ish road trips (we like to take a break and get out and walk around,) I don't expect everyone to have the same attitude. Some people really don't like the idea of a 20-minute "fill up".

What I'd really like to see - what I hope gets developed long term - is a fast-battery-pack swapping system. Bonus points for a standardized form factor from SAE or some similar standards body. This could solve a few problems:

* Faster recharges on trips - potentially faster than filling up a gasoline or diesel vehicle.

* Optimized energy use, at least to a certain extent. Battery packs could be charged off-hours to reduce load on the grid.

* As part of the cost of swapping the pack, the charging station could take on responsibility for repairing the battery packs.

Battery packs are the most expensive single component in most EVs, and I think some people do have anxiety on getting stuck with a five-figure repair bill if their battery pack goes bad.

Obviously there's a lot to work out, both technologically, and vis-a-vis the business model of a battery swapping network.

I think this is a cool idea:

It’s a platform where referrals can register and then they put some money on the line. Say $20.

When an employer calls my referrals through the platform if I end up getting fired in the first six month the people that referred me lose their money (and reputation). If I stay on they get paid that amount of money.

Feel free to tweak the idea but I think it would be great to hire based on referrals in a trustable way.

Thanks for the insightful comment! You’re absolutely right — organizing extracted data into a coherent, semantically meaningful structure is critical for high-quality ML training.

Right now, the pipeline focuses on generating OCR outputs optimized for ML models by cleaning, deduplicating, and segmenting content across modalities (text, tables, figures, formulas). For diagrams and tables, we add semantic tags and preserve layout relationships to aid downstream modeling.

I’m planning to add a semantic structuring module that goes beyond basic layout analysis — something that builds hierarchical, MECE-style representations and identifies entity relationships across sections. That’s absolutely the next frontier, and I really appreciate you pointing it out.

Thanks again for the thoughtful feedback!
