I'm suspicious of that paper. The largest source of non-exhaust emissions comes from brake pad wear[1] and EVs use brakes far less than combustion vehicles. Also the amount of particulate matter put into the air is highly dependent on vehicle speed. Densely populated areas have more traffic, which means cars drive slower and create less non-exhaust pollution.

And it's no longer true that EVs are heavier than comparable combustion vehicles. The Tesla Model 3 weighs 3,550-4,070lbs. The BMW 3 Series weighs 3,200–4,330lbs, though the lightest model is a two door convertible. While combustion vehicles don't carry heavy batteries, they do need exhaust systems, more complicated drivetrains, and bigger cooling systems. Also, more and more combustion vehicles are becoming hybrids to meet stricter emissions standards. That means adding weight for batteries, an electric motor, and a transmission that can handle both propulsion sources.

>It's just EVs where all of the best-regarded models skew larger.

Well, yeah; batteries have really bad energy density and are extremely heavy. Length doesn't affect aerodynamics as much as width or height does, so if you want to offer reasonable ranges, the cars need to get longer.

>It would be one thing if the lack of cars in this size range also extended to ICE cars, but it doesn't.

Yes, because at that size EVs lose their TCO advantage and are strictly worse products than normal compact cars outside of that. They're better in the luxury car segment where you can have twice the horsepower, the same effective range, and more internal space with a decreased TCO because large cars are inefficient- but the Bolt offers none of those things over the Corolla, which is why it's discontinued.
I really hope that I can get access in San Francisco soon. The closest grocery store to me in Bayview is a 30 minute walk across one of SF's riskiest pedestrian intersections and my neighborhood's only bus service is a corporate shuttle. Cruise just announced coverage for the "entire city" but it won't actually include my neighborhood. I've been well aware of Waymo for a long time, and been on the waiting list for over a year now! I've actually seen people getting in and out of Waymos near my apartment, and my limited experiencing riding the Cruise beta has me really excited to someday traverse SF in self driving vehicles. Can't wait.

The Guardian pretty much hates everything. They are picking on everything every single day. It's like reddit but as a newspaper.

I've read them religiously when I was younger but this "everything is bad and we tell you so" attitude is just boring and after a while incredibly toxic.
Surely one can make the point that crypto mining is high energy, making it potentially contribute to CO2 output and e-waste. But when you do, at least try to do your homework.

Not a single (linked) source is mentioned regarding the energy metric, other than a description that it's a guess with supposedly > 100% margin for error.

Not a word on the energy mix. It draws a direct conclusion between energy consumed and CO2 output as if these are 1:1.

The statement that BTC/ETH contribute nothing of value is surely one many agree with, but not factual. It implies that this author/magazine cares about energy use, which surely they do not. There's 5 million energy sucking ads on the page and it's a magazine that can't wait to tell you about the all-new 3 foot long GPU so that you can play your game at 8K on a 240FPS.
My impression back then was that the TV cancon rules were a disaster, and the music ones may have helped more than hurt, after the first 10 years or so.
> My goal was to explicitly set aside the sociopolitical implications. Why? … Because there’s never any opportunity to talk about anything else on HN. One hundred percent of the time, it’s a big discussion about the political implications of TikTok.

I’d argue that “setting aside” the implications is a form of wishful thinking.

Everything you pointed out can be pointed out without discarding the implications or implying that having a stance regarding the risks is somehow equivalent to wishing HN would be banned.

TikTok is primarily an interesting topic here because of those implications and because many folks are quite willing to pretend the problem doesn’t exist as long as they get their dopamine hit.

But it is completely compatible with this reality to point out that the content can be joyful to experience, while acknowledging that the context of that experience is a serious issue.

And if TikTok is banned, people won’t stop creating the kinds of content found there. It’ll just move to the next big thing.
Outweighed substantially is doing a lot of handwaving. Turns out that difference matters[1] when it comes to injury.

Maybe an analogous question would be: would you rather be stepped on by a horse or an elephant? Both substantially outweigh you but I bet you'll pick the horse.

As we Europeans are very far away from seeing any of those, I have a question: how is the refuel / recharge handled? These are EVs, right? Do they some how do that independently, too?
I would also recommend checking out the "Typeset in the Future" website [1]. It does a bit of a deep dive on several films, trying to identify the fonts visible, not only on the title logos, but also on labels, in-universe logos, etc. My favorite is the 2001 Space Odyssey one [2]

You might want to read some of Nick Lanes' work, he's a biochemist researching abiogenesis etc but has written a number of popular works, which I found very compelling

https://nick-lane.net/

He is in particular concerned with exactly the chemistry and physics aspect of the origin of life. In particular his summary of the theory of alkaline "warm" hydrothermal chemistry & the early earth and the origin of life is very compelling.

Essentially such areas are theorized to have created physical protocells at the chemical and energy boundaries between the sea water and the alkaline hydrothermal vents. The naturally occurring molecules there apparently present aspects similar to a hypothetical early cell, and yes, bags of saline. But also the relevant point is the interaction of energy across this barrier. And eventually something "escaped" from this system that was able to "create" a similar system or sustain itself in other environments.

Yes. Electric is being framed as "premium". The electric Jeeps and Ford F-150 trucks are all loaded down with "luxury" stuff and have price tags in the $60K and up range.

Toyota finally replaced their hydrogen-oriented CEO with an electric vehicle guy.
Old CEO: "Toyoda reiterated that he does not believe all-electric vehicles will be adopted as quickly as policy regulators and competitors think, due to a variety of reasons. He cited lack of infrastructure, pricing and how customers’ choices vary region to region as examples of possible roadblocks."[1] New CEO: "To deliver attractive BEVs to more customers, we must streamline the structure of the car, and — with a BEV-first mindset — we must drastically change the way we do business, from manufacturing to sales and service".[2]

Toyota management is scared. The Toyota Corolla, their best selling car, is being out-sold in California by Tesla. That wasn't supposed to happen.

There's a lot of junk comments on HN but there's also a lot of junk comments at top conferences like CVPR, ICCV, and NIPS. The system is just noisy. I've had plenty of inane reviews that clearly break reviewer guidelines (ACs do nothing)[0,1].

Also, I want to remind everyone that ML uses conferences as the main publishing mechanism, not journals. While things like JMLR exist, that's not where papers are targeting.

Maybe we just need to let researchers evaluate works based on their merits and not concern ourselves with things like popularity, prestige, and armchair experts' opinions. The latter seems antiscientific to me. We need to recognize that the system is noisy and Goodhart shows us we aren't optimizing merit.

[0] an example is that I had a strong reject with 2 lines of text. One stating that it wasn't novel (no further justification) and the other noting a broken citation link to the appendix. No comments about actual content.

[1] As another example, I've had reviewers all complain because I didn't compare one class of model to another and wasn't beating their performance. I beat the performance of my peers, but different models do different things. Image quality is only one metric. You wouldn't compare PixelCNN to StyleGAN.
It sounds like the only difference is scale. I have not experienced liquidity issues in practice, because I have avoided the tiny players in crypto.

Have you had liquidity issues selling ETH or BTC?

Regarding hodling, again I don't see how this is different than the stock market. You can try to time the market or you can just hold AAPL for 30 years, understanding that any point it could all come crashing down when you're looking away.

In my experience though, every time I have sold ETH (including at the local peak in Jan 2018) it would have always been more profitable to hold it for longer (since I didn't have an immediate use for the cash).
Thanks for the advice!

The objective is: (1) for the diploma / for fun, and (2) to be more attractive to potential employers / prepare myself for future work. (If I'm going to study on my own outside of work, and the cost isn't absurd, I might as well get the diploma, right?)

The thing I'm getting a bit hung up on is whether it would make more sense to study something that will probably be in demand for a long time i.e. computer systems, or whether I should try to get a foothold in AI since it's so hot right now.

Anyway, I will follow your advice and try to find learning material for specific courses rather than the specializations.
I have written one (gcc-bridge). Fortran is actually a really good fit for JVM byte code. C/c++ is doable, but only with some unpleasant trade offs that others have mentioned here.
Due to forced back to office somebody must drop their remote master studies. Somebody will not see pregnant wife whole day. Somebody will not be able to pick/bring kids from/to school. Another one must cancel his weight loss program during lunch break (funny enough, this guy is the most productive and kindest one in the whole floor). It’s rude silent layoff, only management wins reducing headcount with such clever measures.
Did you get access from the public beta sign-up list, or some other channel? I've been on the waitlist for over a year and have seen people utilizing Waymo near my apartment, but nothing's budged for me. I did get into the Cruise beta, and that just made me positive Waymo will almost completely replace other forms of car transit for me once it's available, but Cruise is very limited.
Well, a focus on being able to get to Mars basically means "figure out how to launch stuff extremely cheaply". I think they've been clear that SpaceX is not going to build a Mars base, they just count on it happening once you've driven the cost for getting stuff to Mars sufficiently low. And if you can launch enough things into orbit that a Mars base is feasible, you'll certainly beat everyone else on commercial launches, too.

SpaceX plows all its profits into this goal. (Its shareholders aren't getting any returns, not for a long time. The SpaceX investors are playing an extremely long game.) And if you constantly use all your profits to improve your capability, you have a huge long-term advantage over companies that exist to make a profit for their shareholders.

>You can’t really change what people want without enacting dystopian/fascist policies.

This is a funny thing to say considering most of these vehicles already come with a tax rebate to entice people to buy them over their ICE counterparts. Are taxes and tax rebates "dystopian/fascist"?
Low quality blogs etc stand out as low quality, LLMs can eloquently state truths with convincing sounding nonsense sprinkled through out. It's a different problem and many people already take low quality propaganda at face value.
A. Tech is huge. 4% of US workforce is the universally cited number.

EU ICT workers are 9 mln out of 193mln workforce, this is 4.7%. We are just not aware of our political power.
If you compare an european style SUV with a sedan / station wagon with similar interior volume, you will notice that the SUV is shorter, and thus easier to park, offers better visibility to the driver, feels roomier, and while less aerodynamic, is actually lighter, so there’s not much increased fuel consumption. Those are reasons why consumers might prefer those types of cars.
Well indeed, crypto fanatics are stock touts for penny stocks.

The biggest liquidity scam here is tether -- that's where you accept one real dollar from a pigeon and turn it into 100s by creating a row in an excel spreadsheet called lol-wewillallbeinjail-soon.xlsx

That's the big real money pump into the system. Hopefully when tether fails, we can see past these manipulated numbers. ie., when people realise the 200bn+ they thought was there was 20bn, we may be able to estimate the actual amount of money being put in.
> It took me a maximum of 5 minutes to download, install, and set up Plex and use it as my home media server.

This is an obvious exaggeration. It would longer just to consolidate media into Plex libraries.

Wow. Here's a clue

sudo cp /etc/apache2/httpd.conf /etc/apache2/https.conf.bak

sudo vi /etc/apache2/httpd.conf
# hint: learn apache once, use many times

sudo ln -s /Directories/you/want/apache/to/see /Library/WebServer/Documents/

sudo apachectl start

Took me less than 10 minutes.

Everybody's arguing about whether Htmx can do this or that, or how it handles complex use case x, but Htmx can do 90% of what people need in an extremely simple and straight-forward way. That means it (or at least its approach) won't disappear.

A highly complex stock-trading application should absolutely not be using Htmx.

But a configuration page? A blog? Any basic app that doesn't require real-time updates? Htmx makes much more sense for those than React. And those simple needs are a much bigger part of the internet than the Hacker News crowd realizes or wants to admit.

If I could make one argument against SPA's it's not that they don't have their use, they obviously do, it's that we're using them for too much and too often. At some point we decided everything had to be an SPA and it was only a matter of time before people sobered up and realized things went too far.
Bike infrastructure is the ultimate boondoggle. It NEVER pays for itself in the US, it literally has nothing but negatives if you look at it objectively.

Bike lanes don't appreciable increase the percentage of trips by bike, they dis-proportionally slow down car traffic, and the bike commutes themselves are probably the worst transit mode in the US.

Heck, bike lanes almost never even _replace_ the amount of traffic that they displace.

All bike lanes do, is cater to a bike lobby that tries to force their hobby on everybody else, at the expense of practicality.
This assumes people buy cars based on the environmental footprint. Sure, a few people do, but most people just look for something that meets their needs.

In my driveway sits a Chevrolet Bolt. In my garage is a Model 3. When I replace one of them, it will be with a crossover. A Model Y, if I could just wave a magic wand today and replace the Model 3. I want a slightly taller car. And not because of some conspiracy of marketing, either, but because it will be a better fit for my needs.
It's the same co2 problem in a different form.

We are supposed to use less materials to make the world a better place.

Wonder what problems will occur 30 years down the line because of this.
"long term", EVs are going to be significantly lighter than modern gas cars because the batteries will continue to shrink. An electric drivetrain is much lighter than an ICE drivetrain.
That moderator idea seems huge to me. That means Moderation is less like a benevolent dictator that people might disagree with, and more like a view filter.

There can then be many ways to implement the filters: voting, dictators, AI, etc.
I was worried about that back in 2018 when it was announced but having heard hundreds of backup sounds (luckily mine is silent as it's from before 2019), they are all chill and mostly imperceptible.
Irreverence, and richness of the environments. Mirrors! Decorations that could be destroyed! Jetpacks! It felt so much freer than prior popular FPS games. A bunch of that stuff become standard fare in FPS games soon after, but Wolf3D, if not being the first to do those things (Rise of the Triad had some of that stuff, and came out first, but was nowhere near as popular as Duke3D) definitely popularized them and was a lot of players' first exposure to some of those features.

It wasn't just goofier than the FPS games people were used to at the time—it felt like a leap forward in realism and capabilities.
Which uses the same Objective-C runtime.
Literally the only thing I care about isn't being addressed and that is news networks posting about social media drama, and that isn't a platform problem, but a news network problem.

People deserve to have a fun place to play on the internet, but the less the rest of us know about what goes on there, the better.
I don't think the train has much to worry about, though it could derail.

The hummer will likely burst into flame and possibly be thrown into oncoming traffic or nearby buildings.
If you apply a certain set of assumptions [0] cereal is a kind of soup only if you add milk. Without the milk is qualifies as a salad. :D

https://saladtheory.github.io/
The Hummer is a limited production expensive vehicle. The original Hummer was also extremely heavy :

1995 Hummer H1 6766

2005 Hummer H2 SUT 6780

2006 Hummer H1 Alpha 7558

2009 Hummer H2 6614

-------Stopping distance

2022 Hummer - 70mph 211 ft

2005 Hummer H2 SUT - 70mph 214ft

2008 Hummer H2 - 60mph 152ft (motortrend)

Bringing up the Hummer as an example of EVs makes no sense, they've sold less than 1000 so far. Just in 2022 the F150 sold 653k units. Let's look at weight for the 5 most popular vehicles in the US in 2022.

------- Top 5 Vehicles of 2022 (Car and Drive, Trims excluded so I used the entire range)

1. F150 4000 - 5740

2. Chevy Silverado 4490 - 5240

3. Dodge Ram 4775 - 6439

4. Toyota Rav 4 3370 - 3655

5. Camry 3310 - 3595

Finally, why does weight matter to you so much? Not stopping distance, safety systems, front end design? If I get hit with a vehicle that weighs X pounds and it causes me to die what does it matter if it weighed 2x the amount? Can you show there's a meaningful difference between 3000 pounds, 4000 pounds, and 5000 pounds when you strike someone?

If you are concerned about EV safety because of weight, don't want to restrict non-EV trucks, and used the Hummer EV as an example I believe you are arguing disingenuously.

This feels... wrong, somehow - we wouldn't say that a 100,000lb shuttle transporter hitting you at 1mph will do the same damage as your 3,000lb car at 35mph. There's way more dynamics at play here.
A vector database is used for things where you're trying query "I have this image, give me a list of the 10 closest images and metrics of how similar they are."

You use a machine learning model (like word2vec, OpenAI, etc.) to produce an "embedding" that describes the image, text, video, etc., which is your "vector".

For all of the other images in your database, you also run them through the same model, and store their embedding vectors in the vector database.

Then, you ask the database "I have this vector, what are the most similar vectors, and what are their primary keys, so I can see what content they refer to".

Think: you want to implement google "search by image". This is the basics of how you'd do that.
It puts the fun into “In 2000 we’ll have flying cars” when the whole XXth century was spent building highways and ramps that were higher and higher into the air, and the whole XXIth will be spent trying to put them underground. The real futurist landscape is a city like Lyon in France, or Amsterdam, where cars are put away and we walk or bike to work.

Interesting considering this post from the WaPo. https://www.washingtonpost.com/health/2023/05/05/covid-forec...

"The White House recently received a sobering warning about the potential for the coronavirus to come roaring back, with experts reaching a consensus that there’s a roughly 20 percent chance during the next two years of an outbreak rivaling the onslaught of illness inflicted by the omicron variant. A forecast from one widely regarded scientist pegged the risk at a more alarming level, suggesting a 40 percent chance of an omicron-like wave. "

I for one am ignoring official COVID stats and focusing on excess deaths and wastewater readings since the government is winding down collection guidelines. Hospitals no longer report infections acquired while receiving care, there no lo longer subsidized PCR test sites, free COVID rapids are no longer available after May 11th.
This is where I imagine things are going for humanity, and it's why I'm terrified. Extrapolate from a single company, to all companies (as those that don't turn over power to AIs will lose out to those that do -- it's a collective action problem) and eventually human activity is just all the AIs doing stuff and us trying to understand or keep up, and eventually giving up. We try to stop them and are prevented and they end up using more and more resources, and the rest of life on earth just ends up extinct.
We’re way too far into a thread for me to have to restate the original point I made in the first post. If what you’re saying is true we’d never see bad implementations of history in SPAs yet we do all the time.

Worth noting is that there really isn't a push to ban natural gas stoves, that is just politics hyping up something someone somewhere said because it gets uncritical supporters spun up and paying attention to who they're supposed to be angry at today.

There are definitely some places that'd like to stop building out new housing with natural gas service, however. But that isn't quite as rage inducing as telling people the leftists are coming for their cherished gas range.
