You are misinterpreting it indeed.

The scenario I am describing is roughly the following:

Suppose we allocate 100K buffers that all have an equal size, and our memory usage is now 10GB. After that point we free 20K buffers, but allocate 10K more. In other words, from that point on we are freeing more buffers than we are allocating.

Now, since we are freeing more than we are allocating, you would expect our memory usage to go down. However, when using the standard glibc malloc on Linux, our memory usage unexpectedly goes up. After this happens several times in a row the system runs out of memory and new calls to malloc fails.
The problem with renewables is one of space and materials rather than energy production. Nuclear is drastically smaller in terms of the land footprint.

Focusing on cost is misleading because the costs are because we haven’t invested in fission in many decades / regulations are fairly insane. For example, the cost argument would go the other way in the 90s when wind and solar were much more expensive. Also, solar provide energy when there’s typically peak demand so you can’t really load shift for DAC. Wind you might be able to do that.
Google is absolutely not going to start taking more risks. They are at the part of the business lifecycle where they squeeze the juice out of the cash cow and protect it jealously in the meantime. While Google gets much recognition for this research, I believe they are incapable as a corporate entity of creating a product out of it because they can no longer capable of taking risks. That is going to fall to other companies still building their product and able to gamble on risk-reward.
hey I'm new to HN and was searching for some posts on "XMPP" and other chat backends and saw you posted on https://news.ycombinator.com/item?id=27635547

I am considering using ejabbered and wondering what your thoughts are on it today. Thanks
You tell it, "do it all over again, now with less inner turmoil". Not joking, that's all it's going to take. There are also a few diffusion based speech generators that handle all sounds, inflections and styles, they are going to come in handy for tweaking turmoil levels.

IMO, it's not worth over thinking. The rates are very good, but you are limited to a relatively small amount of money. My wife and I both bought an I bond at the recent rates. If we're lucky, we'll make about $1,000 each on them. You can do a lot with $1,000, but it's not like we're talking about life altering amount of money here (in the context of people who can afford to put $10K in an I bond in the first place). We basically used money that would ordinarily be earning less interest in some kind of emergency-funds checking account.

It probably would not be worthwhile in the grand scheme of things to take $10,000 from some kind of actual investment account and move it over to these I bonds for a brief duration.
> Python's already the main contender for AI/ML, so I don't think anyone's arguing that python is too slow for serious work.

I love me some Python, but for ML, the "serious work" is handled by C/C++ libraries on the GPU or CPU. Python is provably slower than C/C++, vut being "too slow" or not depends on the domain and/or budget.
Maybe column-oriented formats like Parquet never became popular in bioinformatics because new file formats usually come from people developing tools for upstream tasks such as read mapping, variant calling, and genome assembly. They are the ones who work with new kinds of data first.

Those upstream tasks tend to be row-oriented. You often iterate over all rows, do something with them, and output new rows in another format. Alternatively, you read the entire input into in-memory data structures, do something, and later serialize the data structures. Using column-oriented formats for such tasks does not feel natural.
The term "creative" is so pretentious, as if only content generation involves creativity.

Your post reminds me of all the photographers that said digital photography would remain niche and never replace film.

The current models are toys made by small groups. It's not hard to imagine AI generated film being much more compelling when the entire industry of engineers and "creatives" refine and evolve the ecosystem to take into account subtle strokes, wrinkles, movement, shots etc. And they will, because it will be cheaper, and businesses always go for cheaper.

It's fun stuff to mess with, but one difficulty is that you can't really affect time-domain issues by modifying output frequencies.

That is, there are likely both issues induced by the phase response of the speakers themselves as well as issues introduced by reflections in the room which will cause uneven frequency responses in these measurements. These issues are inherent in speaker systems and acoustic spaces.

If you have a really resonant frequency in a room, notching that frequency can help, but then you're compromising that signal; a more typical solution is to address reflectivity in the space.

And I hate to be a snob about mics, but yee, I do not like that specific mic-- of the many dozens of mics I have used it's memorably bad. And you don't need an expensive mic to do these measurements; there are a lot of ~$60 omni-directional measurement mics that work fine, as their low/mid frequency response is good enough for these tasks.

So all in all: hooray for folks experimenting... once you start playing with frequency modification, start investigating phase response and modal reflections in rooms, as they are super interesting.

Like, if you want to hear something really neat, put on a recording of a 120hz sine in a very reflective room, and you can walk around and hear the nulls and additions. And then you can find different frequencies and start to come to terms with the complexity there. Quite a fun exercise.
You're making less sense, try moving your argument in the other direction.
Vudu while it was owned by Wal-Mart was quite reputable for purchasing digital movies and TV for some similar reasons to following iTunes' lead and was at times "the blue collar iTunes Movie Store".

Vudu's current owner, Fandango Media, I have a lot less trust in because they have burnt a few bridges with previous digital movies sites (including one of their same brand; they briefly ran a Fandango branded digital movies app that closed without much notice or refunds, to be rebooted as FandangoNOW months later, in part because they bet on UltraViolet and didn't want to just convert UltraViolet purchases to Movies Anywhere like Vudu and iTunes did during that same time). So far Vudu has still seemed to be doing well under the new ownership, but that distrust in the new owner still sews seeds of doubt.

Speaking of Movies Anywhere, that is still an assurance that I trust when making purchase decisions. Even after UltraViolet died, possibly especially because UltraViolet died (and the way at least iTunes and Vudu handled that transition). Movies Anywhere seems to have won out because it is technologically simpler. Plus the Disney backing seems to work in its favor as Disney has some reason to make sure Movies Anywhere does right by families and doesn't tarnish their brand by association. I'm a little less particular which store I buy from if it supports Movies Anywhere. For movies that still aren't yet Movies Anywhere I'm much more cautious. (This was why I avoided Steam's brief foray into movies, for example. They worked with non-Movies Anywhere studios and it didn't feel all that shocking when the experiment failed and Steam stopped selling movies.)

I had this limitation on my account for a while too. It was because I was upvoting flame-bait comments that had been grayed out. My personal reasoning at the time was "but the other poster started it" (these were deeply nested angry comment chains). After a couple of months I emailed dang to request if I could get real voting back and he took the penalty off my account, after explaining why it had been put there in the first place.

If you see an ugly exchange of comments,

DO downvote (or ignore) provocations.

DON'T upvote provocative retorts, even if you think that the reaction was justified.

Nothing in life is 100% perfect, but as a business owner I see quite a few risks with a business handling credit cards.

Even when you deal with customers properly and fairly, you take a risk handling credit cards because you can deal with false disputes and chargebacks long after you've already provided the product or service. It doesn't matter if you can provide detailed records proving that you provided the service (including signed shipping records and emails from a customer verifying delivery) the payment dispute is judged in a non-transparent process by a busy person that barely puts 30 seconds into checking your documentation and usually has much more of an incentive to favor the fraudster.

And on top of being out on the product and losing your payment, you also have to deal with paying an extra chargeback fee to the payment provider for them to have to deal with the dispute.

Worse still: every one of these false disputes holds the potential to trip some random algorithm at a payment processor and effectively kill your business by them blocking your account due to too much fraud. It's not super common, but it does happen that businesses get destroyed due to fraud.

As long as you walk free and have at least 1 arm, nobody can ever prevent you from handling cash.
Renewables have yet to demonstrate the ability to replace fossil fuels in any meaningful way. They seem to top out at 10-20% of the energy mix. France achieved net 0 many decades ago because they went all in with nuclear whereas their neighbors that went with renewables haven’t gotten anywhere close to that.

The best time to plant a tree is 20 years ago. The second best time is now.

I mean, this is a company which stoves way money in tax havens. Apple may be incorporated in the US, but it is pretty much a global company.

"The fission of 1 g of uranium or plutonium per day liberates about 1 MW. This is the energy equivalent of 3 tons of coal or about 600 gallons of fuel oil per day, which when burned produces approximately 1/4 tonne of carbon dioxide."
https://www2.lbl.gov/abc/wallchart/chapters/14/1.html

Uranium is everywhere, enriching (separate 235 from 238) is a mechanical process (no chemistry involved).

"Uranium is a naturally occurring element with an average concentration of 2.8 parts per million in the Earth's crust. Traces of it occur almost everywhere. It is more abundant than gold, silver or mercury, about the same as tin and slightly less abundant than cobalt, lead or molybdenum."
https://world-nuclear.org/information-library/nuclear-fuel-c...

And its "combustion" is carbon free. Nuclear power plants works exactly like coal or gas ones. A big boiler. Water is used to "slow" the neutrons to keep the reaction going, and also use to transport the heat.

Nuclear technology and engineering is quite impressive.
While I agree death is a bit extreme, we do need to craft a system where knowingly providing data on American Citizens to enemies of this nation carries severe and unfair consequences. The punishment does need to be oversized, to serve as a deterrent.

Do we know if this was deliberate or accidental? If the contract was explicit, and this individual knowingly violated it, then the intent is pretty clear even if the goal was not to aid China but rather to save money or similar.

We see how pitiful punishments are for malfeasant corporate executives - and we see how often they recid or are copied by others cleaver enough to calculate the punishment does not outweigh the crime.

The consequences for giving sensitive citizen data to China, Russia or any other nation should be severe enough to make folks think very hard before trying it.

Our election meddling problem will only grow worse in the future as our adversaries grow more and more sophisticated... best we don't help them along.

There is no world where fusion would be more abundant without being cheaper. Sure, it's nice that you only need water to get half the fuel of a fusion power plant, but even for fission, uranium is a fraction of the cost. The reason fission isn't already providing us with abundant power is the huge cost of the extremely advanced fission reactors - which look like lego blocks compared to a fusion reactor.

And 1 fusion reactor will generate nowhere near the power of the largest fission reactors we already have, in any design considered realistic today.

Not to mention, the extraordinarily expensive fusion reactor you build will become too brittle to hold itself up in the span of 10 years at best, because of the neutron bombardment - turning your massive investment mostly into highly radioactive waste that you'll need expensive robots to disassemble and replace.
For data privacy / security, I think a simple rule would be effective provided it had teeth:

Any organization that holds personal data can be sued if such data is misused or exposed (even if hacked). Further, ensure that people cannot revoke their right to sue. Nor can they agree to any damage reduction in advance.

Otherwise stated, make every CTO committed to collecting / storing the minimum amount of data.
> I’m curious about facilities like the one in NJ that produce power by burning trash. I wonder how viable they would be on a larger scale.

Incinerating already sequestered carbon via burning hydrocarbons is a path to nowhere. It’s a profitable business for sure, but so is mining coal.
> It’s hard to relate national finances to personal

People keep saying this and it’s not really true. Even MMT really can be translated to personal finances.

Here is the simple explanation:

Households and individuals consume the goods they buy. Some excess goes towards investments.

Governments do not consume. Building a road/bridge/building/dam is an investment to “have the nation make more money”.

Even when government spends money on “dumb things” a F35 while over paying significantly, it’s an investment. Even if this project doesn’t become “something” itself it can still be a huge national investment. 1. The people who worked on it will spend the money they earned. 2. The people got training that was useful. 3. Technology likely progressed in many small ways that aren’t the end product (eg better wind tunnel simulation, or better GPS chips) and even by learning “what not to do next time”. That said, obviously the government should always aim for better investments rather than worse investments.

Imagine a household that kept taking debt to buy houses and renting those out. As long as the ratio of TotalRent:TotalDebt was healthy at N-1 houses, then the same TotalRent:TotalDebt ratio for N houses continues to be healthy.

No money ever spent on consumption, only on investment. Therefore NationalGDP:NationalDebt is the ratio to watch for. That is how you understand national finances and relate it back to your experience.

Additionally, the household could only have 5 houses in the same neighborhood. So a financial shock could hit it badly. The nation has X TT of investments that are all distributed across city centers, rural areas, and even digital. It’s not just diversified, it is the whole pie.

A large enough shock to cause a destabilization of the NationalGDP:NationalDebt for a country as large as the USA is roughly enumerated as: an extinction event (or close enough), a second US civil war, or a declaration of active war against the USA on US soil. It could also happen because of terribly large scale corruption but it’s unlikely at the scale of the USA.
The sum of all things speaks for itself. We have an excellent product and a written statement about how all current developers are bound by a religious covenant. And no contributors accepted. If you want to create a fork and welcome lots of contributors, then I don't see how the CoC as written would stand. Of course this has to change.

> That is a lot of effort to complain about SQlite's Code of Conduct.

Anyways, given that the super-majority of the blog post was about features and the different directions that sqlite is being pulled in, and the only singular mention of the CoC was a paragraph at the very end of the blog, I don't really see the summarization of the blog post as just about the CoC as honest.

I don't think this matters, new movies and TV shows already have to compete with a huge amount of old content, some of it amazing. Just like a new painting or professional photo has to compete with the billions of images already existing on the web. Generative models for video and image are not going to change the fact we already can't keep up.

Mental health institutions were nightmares. They were the places that in the 1950/60s did lobotomies and were still doing electro shock treatment into the 80s.

If it takes 8 years to move 10%, does that mean it takes 16 years to move 20%? Would it take 80 years to move 100%?

Doesn't really make sense, does it, given that it didn't take 80 years to ramp up originally.

Apple couldn't move out of China overnight, but it could move faster or slower, depending on how much of an impact to the bottom line it can take.
I think the point being made is that if Apple/whoever was willing to pay for it, you can setup the supply chain and get the workers wherever you want. It might cost more, sure, but it can be done.

However, you can't just extract energy from somewhere that doesn't have it. No matter how much money you want to sink into it. If there's no oil/NG/whatever, that's that. Trillions of dollars wont make it appear there. Trillions of dollars does let you setup a nice supply chain and labor force in the US though.
Even if this was a case of incompetence, it's highly unusual to store sensitive government data on an offshore server.
