Do they also have a benefit similar to the compression that comes from record re-ordering in column databases?

It's not just that you need to read a smaller section of disk to scan the same amount of interesting data - it's that that data also takes up considerably less space than it otherwise would.
What about capacitive and inductive losses. These are significant in AC transmission lines, depending on their construction. I believe that's why high voltage interconnects between different countries are usually DC and use rotary convertors at the ends.
What's harmful in that? Where are the studies that show that it is harmful?

Look at a market where repairs are normal.

Car manufacturers get a reputation based on used vehicles not just new cars. High resale value translates into higher margins because higher trade in value means purchasers have more money for their next car. Similarly people who used to buy used cars will often move up to buying a new car when their economic situation improves, that makes used cars a valuable form of advertising.

In that context Apple likely looks at the used market as quite valuable as long people still consider used iPhones as durable devices worth paying a premium for. They don’t need to sell you 1,000$ phones every year if you’re willing to buy a slightly used phone for 500$ someone else can more easily keep buying the next generation.
And now someone flagged it. Good job killing a perfectly fine discussion.
AC is quite a lot more dangerous than DC for humans at ~hundreds of Volts. ElectroBOOM has made a nice demonstration of this: https://www.youtube.com/watch?v=snk3C4m44SY
Apple's attitude about repair is a HUGE knock on the brand, at this point. There is no justification for it, apart from greed. Even if they are right and the repair isn't great, which does happen of course, a rational person will blame the repairer, not Apple. So for them to make these paternalistic claims is another HUGE knock on the brand - not only are they greedy, they lie to justify their greed. I don't care how good their products are (and the M1 based laptops are damn good) I'm not giving Apple a dime until this changes (and the batteries are no longer glued into everything).

> Our past meddling with ecosystems and biologies have often produced unintended consequences to great detriment

…we also effectively eliminated hunger, whole classes of diseases, and greatly extended healthy human lifespan across the planet.

Ultimately I think this attitude stems from the premise that there's a choice of some "stable state" that humanity abandoned, some kind of safe well balanced haven that we left to "meddle with ecosystems". There isn't, "ecosystems" tried their best to kill us at every point of our history (it seems there was a moment there were just a few thousands of us, nearly wiped out by a natural catastrophe!), and the only way to avoid that is to "meddle", learning from our mistakes and becoming better stewards of the planet.

We were, are, and always will be walking on a tightrope, we are just learning to do it better.
DC will one day be ubiquitous, but I think that day is >50 years away.

Today, DC is common in small 'islands'. At a small scale, you have DC in your phone charger and USB power supplies. At a medium scale, DC is used in high speed electric car charging. At a large scale, DC is used for undersea electricity transmission.

DC has benefits of better making use of available conductors and insulators - for a given mass of copper and plastic, more energy can be transferred from A to B at a given efficiency. Modern DC/DC converters can convert voltages more efficiently and using less metal (ie. cost) than AC transformers.

However... AC is still the standard. And changing power standards is awfully slow, because power cables in the ground can easily have a lifespan of 50+ years, and there is a chicken and egg problem involved with deploying a new standard.

We do (pretend to do) when it's easy enough. But mostly we don't. Some examples:

- deforestation

- biodiversity loss

- overfishing, bycatch

We even subsidize the sectors causing most of the damage. But for for a regular joe wanting to have water ... sure, that's easy enough.

What the counterculture movement of the 70s and 80s presented, at least externally through hair, clothes, tattoos, piercing, etc is now post mainstream.

It’s like this huge portion of society “rebelling” against a Nixon that no longer exists, or is a much smaller portion of the population than it was when it was an oppressive majority.

They now have the raw data for the CAD files used for manufacturing the keyboard.

We understand some CNC instructions, but there's no good understanding of the control mechanisms or sequencing.

One day we'll identify the keys, but we are very far from the driver, and more importantly, from identifying what each key does.

Oh, we did discover that changing specific bits in the raw data causes the keyboard to fail in interesting ways.
I agree to some degree.

Maybe it’s because Reddit has so incredibly many subreddits…? Reddit as a whole is therefore, naturally, very fractured. Whereas on HN we all share the same frontpage, the same ‘Ask Hn’, and 'dang is the moderator of it all. HN also has quite generous profile pages, where you can write a lot, or nothing at all. And many of us who comment here work in the same industry.

Perhaps these factors contribute to making HN more of a ‘place’?
Maybe none? These are news sites. ChatGPT still doesn't know about anything that happened after 2021, apparently hundreds of millions of users don't care. The dataset is already very stale but it's still very useful.

Also, the lesson of Google News was that news is a commodity. The world is full of websites reporting on the same events and giving those reports away for free. They aren't all going to block GPTBot.

And then finally this might even be a good thing for OpenAI. One of the criticisms of ChatGPT is that it has a left wing bias, probably a result of training on left wing biased news media. If NYTimes/CNN/ABC stuff no longer shows up in the training set, ChatGPT's views may come more into line with that of the average person.

false analogy. if openai is downloading and copying and distributing copyrighted material internally and then compressing that information into a model that can reproduce it later and selling access to that model that is a very different thing.

Fair enough, I'm just very aware of the doxx culture we live in and the insanity of the modern internet.

You're right legally, but obviously the GDPR is not fully followed -- Big Corpos just ignore it and pay the fine, and small companies can skirt it.

I don't understand your overall point about "data" though. Do you mean for free usage when people accept cookies from their logging, or just for customers of the API since you make an account?

In any case it looks like the FAQ now links to the parent company, but I could have imagined it just being a guy who didn't want to get doxxed or wanted to stay private.

I think being able to make a website or tool or thing and say "hey check this out" and stay anonymous is a key part of the internet, and frankly I don't mind if they make a small amount of money on the side. I know this is probably Ketzerei in Germany but in Anglo countries it's sometimes notoriously hard to track down corporate structure to people and such.

Germany is definitely incredibly pro copyright though so that probably plays a role.

Maps are hashtables, Vectors are a contiguous area of memory where each element can be access by index referring to a specific address in that memory.

Vectors are usually also homogeneous about the data they hold, because each element should occupy the same fixed amount of memory, such as i*item_size gievs you back the offset of the element i in memory.

> Rust's cuts down on total development time because of the extensive checks it performs

Plus, there's rust-analyzer/LSP. It works in real-time, and catches basically everything one might care about, no compiler needed. It's kind of like a static interpreter.

My use cases are modest, but so far, once r-a was happy, the compiler was as well. Mileage might vary when using crate features, possibly? Inactive features are (until Rust 1.72 at least) invisible to the compiler so issues might arise only at compile-time there.

> I'd rather correct tests than fast tests, just like I'd rather a thorough compilation over a fast one.

The first one is a false dichotomy though. It's not like people write fast but incorrect tests whenever given a keyboard.

Giving up caffein is the single most important thing most people can do to improve sleep quality. Wikipedia says "Caffeine is the world's most widely consumed psychoactive drug", so it's obvious why coffee is so addictive for many. It is very hard to stay away from coffee, when it is literally everywhere. Somebody is always brewing coffee at the office, every street corner has a café, every meeting starts with someone serving coffee. It doesn't makes things better living in Norway, which has the worlds second highest coffee consumption per capita.
I don't know if hemp plastic is better or not, but I wouldn't take a manufacturer's website word for it, as they're clearly not an impartial source.

That website also contains a number of red flags: disable text selection and right click, excessive use of superlatives, no details on why it's better/less toxic than other bioplastics, no hint of even the slightest study on hemp plastic.

Maybe hemp plastic really is loads better, that would be fantastic! But that link didn't convince me.

Each decay event is when radiation is emitted.

So: very short half-life is good, because the element turns into something else very quickly and ceases to be a problem. This is the nanoseconds-to-days range.

Very long half-life: not actually all that radioactive. e.g. U238 itself with a half-life in the billions of years.

Medium half-life: emits a dangerously high level of radiation in the process of decaying. This is the real problem stuff as "medium" can mean "centuries".

> 4GB RAM

So, an 128x increase of ram requirement (32->4096) in ~21 years. Do you actually get 128x more of anything? Does it do 128x more? I mean sure, the icons are high-res, so maybe a few 100kB of ram for that, but 128x more? Even the 2016 version required 2 gigs less... and the 'whats new'? https://support.microsoft.com/en-us/office/what-s-new-in-off...

For some things, I agree... a jump form notepad.exe to word brings many new features and an increase in memory usage... but the new word versions keep growing and growing in size but the new feature set doesn't bring anything that would excuse such a large increase in usage.

Yes, teams was broken, and it used less memory if you used it in a browser than a native app.. so there's no excuse for that, especially since the native app was mostly a browser in disguise.

I mostly blame lazyness and overspeced developer computers for that... why optimize when you can be lazy if you have 128 gigs of ram? If we made developers use (for testing) 5 year old, mid-tier laptops bought that were available in supermarkets (so something your grandma bought in walmart on a sale 5 years ago), the world of memory usage would be a much nicer place. Same for mobile phones.. test the app on a 3 year mid-range phone, and if it's too slow, it's going to be too slow for many users.

The crime was blocking the highway. If there were no police at all, that crime still would have been committed.

I'm all for civil disobedience but at least if I'm not mistaken, when Dr. King organized so many marches and sit-ins he guided his followers to peacefully allow themselves to be arrested -- overflowing the jails and courts was an intentional part of the civil disobedience. He himself was arrested many times. That peaceful action made media coverage of events like the police violence in Selma, Alabama more impactful than they would be otherwise. I grew up in a "violent leftist" city, which was a major hub for the Weathermen and various bombings of law enforcement buildings during the era of "Days of Rage", but the general advice for attending protests/marches in the early 2000's was "bring a check in your pocket to fill out for bail", not "run away from the police and attempt to avoid getting arrested" or "attack the police and burn down the police stations".
The "war of the currents" was between Edison and Westinghouse. Tesla worked for both of them, but had very little influence on this issue. In the 19th century, using AC power was necessary because transformers were the only way to generate high enough voltages for long-distance power lines. This is no longer the case in the age of high-performance semiconductors.

In your calculation, you are comparing apples to oranges. An "AC-DC switching power supply" is just a rectifier followed by a DC-DC converter. There is no way for your "Case 1" to be more efficient than your "Case 2" because it simply contains two more conversion steps. This is exactly what the Fraunhofer project is aiming to eliminate.
Yes. The original commenter is a bit behind the times. There is also reliability advantages.

I think energy cooperatives serve as a good model for utilities. Not a private for profit company sacrificing safety for profits, but also not a wasteful inefficient government entity.

We had an energy cooperative that serviced our previous house and the quality of service was excellent. Power was restored quickly after storms, customer service was friendly, and best of all, because everyone was a "member" instead of a customer, we got a check back every year with any excess profits that they made.

Anecdotal of course, but our current energy supplier is government run and compared to the cooperative it is much more expensive, customer service is worse, and outages tend to be longer.
