Garbage collectors are notoriously difficult to predict the performance of at runtime compared to deterministic object lifetimes. A GC program also requires many times as much available RAM as a deterministic-lifetime program to achieve the same task with the same level of performance.

Rust lets you code safely in much the same way as you would in a GC language, without the performance and determinism drawbacks of GC. You pay a bit for that in terms of following the borrow checker's rules, but that's not too much a burden once you decide to learn them and get used to them. There's a reason why Rust has supplanted Lisp and Haskell as the new smart kids' toy.

Notice how the metallic orbs are only ever captured from moving aircraft, generally looking down on them. That's because they are balloons, and the aircraft's motion give them the appearance that they're moving quickly relative to the ground behind them, when in fact they're moving quite slow, as balloons do.

Either that, or the aliens made their craft transparent on the bottom but forgot to make them transparent on the top.
> Homelessness is caused primarily by a lack of homes.

That is absolutely not true. Not even close.

Mental illness, drug and alcohol abuse are major factors. Dozens of studies show this. I've seen numbers as high as 76% having substance abuse and severe mental illness.

One study from 2017 says 80% mental illness, 88% drug abuse and 59% alcohol addiction. There are studies with lower numbers. In most, if not all, of these, the government entities who publish them will typically change the definition of "homeless" to artificially reduce the numbers and make themselves look good. There are two ways to fix homelessness: You make them disappear (put them in a building, creative counting, etc.), or actually address the real root causes --which nobody is doing or even talking about.

Saying the issue is lack of homes implies these people could actually pay for a place to stay. They cannot. They are sick and/or addicted to something. They likely cannot work or earn even the legally minimum wage without a massive intervention to get them back to functional status.

In a free society we do not have the legal means to round-up sick people, get them cleaned-up, help them, rebuild them as necessary and then put them back in circulation. We just don't have that legal power. People do as they wish and there's very little society can really do to help them.

Throwing them into a buildings merely (and conveniently) hides the real problems: Mental illness and addiction.
I tend to see zeroed memory as an advantage in the vast majority of cases. And when it's actually significant overhead then s/calloc(/reallocarray(NULL,/

The thing I like about almost always allocating through calloc is this: I know that if my code is somehow not initialising memory properly, the resulting bug will be the same each time, and therefore faster to reproduce and debug. Not that I misinitialise my memory very frequently anymore, it's not that hard to get right.

Surprisingly often, I've found that so much of my data should probably default to zero anyway, so it doesn't really matter all that much.

Calloc can over-allocate, which i always found annoying myself, although at least with calloc, you know that if you only index the pointer modulo the n you passed onto calloc, you won't invoke any demons from the underworld.

But yeah, in general, to really know what you're doing in C, you kind of have to understand memory allocators at a fairly deep level, because the footguns are aplenty. You need to have a mental model of the heap and stack.
He does hardware, not software (wherein AMD's problem lies).

Hardware-oriented companies often struggle to build good software stacks for the simple reason that they don't know what's good or bad in software, so they don't know who to hire.
I put on my firewall a block for incoming traffic for all IPs outside Europe which helped a lot with the quantity of attempts.
"Zoning and planning issues can be dealt with trivially by the state almost anywhere, they just aren’t fucked doing so (we have this issue in Ireland)."

This seems to not reflect reality in the US. There is strong local resistance to construction especially if it's for poor people or worse homeless, leading to tight zoning and rejection of projects during the byzantine approval process. If the government tries to build something, the EPA (environmental protection act) also allows anyone to request that a environmental impact study needs to take place. The study can take about a year and there are no teeth, other than causing delay and cost through the study. Nothing needs to change based on the findings, it's just another way to drag things out and increase cost on projects someone doesn't like.
Completely anecdotal: I know that my partners younger tween/teen relatives are into VR. They're the next/current generation of growing consumers.

Don't discount what the younger people might adopt and make into something huge just because you yourself don't see the point yet.

It'll be interesting to see what the teens of today are building with VR when they're in their 20's & 30's.
Interestingly, this is not a new result; people have been doing stuff like this since at least the 90s, most notably Steve Potter at GA Tech and Tom DeMarse in Florida.[1][2] (I built a shitty counterstrike aimbot using a cultured neural network in college based on their papers.)

There was a lot of coverage back in 2004 when DeMarse hooked it up to a flight simulator and claimed it was flying an F-22 [3] (lol, but I don't blame him too much...)

The basic idea is that if you culture neurons on an electrode array (not that hard) you can pick some electrodes to be "inputs" and some to be "outputs" and then when you stimulate both ends the cells wire together more or less according to Hebb's rule[4] and can learn fairly complex nonlinear mappings.

On the other hand, these cultures have essentially no advantage over digital computers and modern machine learning models. Once you get through the initial cool factor, you realize it's a pain to keep the culture perfectly sterile, fed, supplied with the right gases, among many other practical problems, for a model which is just much less powerful, introspectable, and debuggable than is possible on digital computers.

> force detox

Forcing people to detox is a grave violation of their right to body autonomy. In general people tend to react very badly when their body autonomy is violated: the results are trauma, CPTSD, suicide. I suggest we try other solutions first, starting from a place of compassion, empathy and scientifically tested medical advice.
In the video it appears to be moving faster than a jet. That seems unlikely behavior for a Mylar balloon, no? On the other hand a sphere seems like a terrible geometry for atmospheric flight no matter your technology for propulsion.
Five Communities Improving Equitable Wellbeing
>Wellville is a 10-year national nonprofit project to achieve long-term, equitable, community wellbeing. We serve as a catalyst for five US communities – the Wellville 5 – as they work to improve their health and wellbeing through resident-centered, multi-stakeholder collaboration. The Wellville 5 will inspire other communities to copy (and improve upon) their work and to promote change in how our nation invests in its people, institutions and systems.
The use of common sense does not preclude the use of evidence. In fact, when good evidence is available, it suggests it.

You are arguing a distinction that does not exist.

I like the idea, but I don't think a homeless person should be entitled to free housing in one of the most expensive real estate areas of the world. Why work full time at mcdonalds to pay rent when you could just be a drug addict with a free house? Maybe we could create free housing communities where real estate is a bit cheaper.
I have so many bookmarks which I have never revisited ever.

What counts isn't some abstract storage concept but the UI and UX to manage them. Bookmarks are this drawer in your basement where you have to actively spend energy to find them. Tree tabs are self organizing. How they are are stored is irrelevant to me.
Ask HN: Do you think there will be social mobility after AGI?
I consider myself an ambitious person. And I like the idea of working my way up in the world through hard work, calculated risks (and of course luck / seized opportunities).

That being said, recent developments in AI have me wondering how social mobility might work in the scenario of AGI. If our human efforts / intelligence is relatively inconsequential compared to that of AGI applications, how does one climb up the socio-economic ladder? Curious to see HN takes on the topic...
It's fascinating how brain cells outside of its host can do simple tricks like play pong. Perhaps these scientists need a new marketing department because DishBrain isn't quite appetizing.

When masking was first being mandated, I watched a science-guy video as he demonstrated how to properly handle a mask, donning and doffing, shaping the nosepiece, disinfection for reusable masks, etc.

Then I saw reality, where a medical professional would politely remove her mask to sneeze.
> Can you point me to any of that research? If I'm wrong I'd like to update my belief

I'm curious why you feel the need to update your beliefs if you're wrong if this is your standard for evidence. Shouldn't you not have a belief in the first place?
Good to see that the archive link is now posted on top but why not replace the original URL?

And to the subject, journalists (and humanists in general) don't understand that homelessness is sometimes a self inflicted predicament.

It's a moral fight for respect and responsibility and money can buy neither.

Basically governments need money to have value, even if it is proven to be useless.

They can't solve the real problem which is that moneys value is backed violence.

And energy backs that violence today more than ever previously in history and in the future.

The society we have has to change now because we don't have the coal, oil and gas to feed the violence that backs the value of money.

Ultimately war is money and money is war.

Eventually as energy peaks, kings will be beggars and beggars will be kings.
Your comment is wonderful, and I agree.

I'd only add/clarify that it's much more valuable to learn the major programming paradigms (OOP, functional programming, massively parallel programming, etc.) than to learn specific languages in terms of being well-rounded and setting yourself up for success.

If you know a paradigm, then for the most part, learning new languages in that paradigm is just a matter of learning new syntax, which is a considerably easier task.
The problem with flop houses that don’t have drug and alcohol restrictions is that the other residents suffer and things fall apart quickly. These aren’t people with great self control. Even homeless with drug and alcohol abuse problems will stay away from these places because they are too dangerous.
I don't think the frame of "does this help or hurt a particular state" is a useful frame for the problem.

We should look at it as "does this help or hurt people"

Christopher Strachey and the dawn of interactive text
I doubt they plan to just use it to talk in-house. At low latency trading shops almost all internal systems carrying market data or order entry flow avoid using IP/TCP. Everything will either be on a single box, with different processes pinned to different cores busy-spinning over IPC, or perhaps some kind of reliable UDP stream if a network hop is needed.

TCP is still used everywhere when it comes to talking to brokers and exchanges though. Even if you're jacked straight in to the NASDAQ with an FPGA you're still shooting TCP packets over the cross-connect.

Cheap and quick has been the carpenter's mantra since the dawn of time. One look at the inside of an old piece of furniture shows how little effort went into things that weren't readily seen.

Mortise and tenon joints are fast and easy (read: cheap and quick) to make with a chisel and hammer. You can bet carpenters of old would be using nails and screws to build all kinds of things, if they were as cheap and abundant as they are now.

AMD's focus was always on pure compute power at a good price. And they always beat NVidia at that game. AMD cards always had the highest hash rate per dollar in crypto mining. AMD has 100% of the console market and the fastest iGPUs by 2x over Intel.

NVidia decided to use gimmicks to sell their cards including texture compression, lighting tricks, improved antique video encoders, motion smoothing, bad proprietary variable refresh rate, ray tracing, cuda and now machine learning features.

Nvidia is fortunate that machine learning has taken off. That is masking AMD winning market share from weak overpriced NVidia 3D products!
I am not advocating for shipping anyone off to anywhere (it wouldn't be effective). However, the prevalent opinion that we just need to throw more money on this problem, or just silently suffer in the name of compassion is/will make things worse.
Your comment does not provide any concrete example. Even if what you say is true, access is a real issue. You think homeless people would know how to find those $1000 options if a random person cannot find them via a simple search?
Of course it is not working, because people who decide where these money should be spent never really want to solve this problem.
I hope you never end up in a situation where people decide not only to leave you in pool of your own urine on the sidewalk, but to feel righteous about their activism to make sure you're left there.
This isn't the first time there's been a BS story with this plot. A few years ago I was hearing it about a supposed AI artillery system in Japan that went wild and killed its creators. Never happened.

People keep falling for fake news ripped off from Ghost in the Shell.
If, say, it came out that 100% of the local homeless population became homeless elsewhere and were bussed to California

If this were the case, I suspect proposed solutions would shift away from building and maintaining shelters and Permanent Supportive Housing (PSH), and more toward helping people return home. The latter would require much less than the $600MM+ the DPHSH spends each year.
Nothing here suggests they're running short on funds
There won't be. If AGI exists under current economic/government systems it will take everything.

Dry shelters are arguably a massive part of the problem.

Homelessness, in the volume it exists, is largely a result of social/cultural decay in my estimation.

It's the result of degradation of family and community and other important social structures.

On one hand we have made housing something like a Ponzi scheme so that some may realize profit without effort. Nothing is free. When someone gets without producing someone else loses. Housing isn't the only example of this either. Much of our economic reality is one make-money-at-the expense-of-the-other-guy-while-giving-as-little-as-possible scheme after another.

But also we have embraced "liberation ideology" largely starting in the 1960's. Yes, our former culture was oppressive, stiff and judgmental. Women stayed home and cooked. Get divorced, and everyone will give you the stink eye around town, so I hope he doesn't beat you too badly when drunk. Gays stayed in the closet. The mentally ill were forcibly confined and abused. "Bums" got beat up by the local sheriff and dropped outside the town limits instead of being given free needles and a pass to shoplift. Church ladies gossiped and judged and it was a very hard time being "different". Hope you belong to the right secret men's organization because that's how you get in with local banker and judge and get a start on the good job ladder.

But also people helped one another. Encouraged one another (even if it was through judgement and social pressure and occasionally violence). There was a greater sense of community. People at that time were culturally closer to the era when they had to band to together to travel to and settle a new land and build towns.

Now it's I have a credit card so I'll do what I want and move where I want and this place I live isn't a community and I don't talk to my neighbors anyway and one city is another really and everything is anonymous and transactional and no one goes to church anymore. Sexual freedom without regard to consequences (especially the resulting children and lack of long term relationships). Drug use is fine, it's a personal choice, and besides I'm dealing with so much inner pain and trauma and no pain should ever be. In fact the doctor may just give you something to numb you and shut you up altogether so you can keep being a good cog and not a squeaky wheel.

So, we are seeing the results of all this. What we had before wasn't good, but this isn't either.

I don't know what the answer is. I believe people should do what they want. I do what I want personally. Just observing and noting what I think the root cause might be.

Maybe our real culture in America hasn't developed yet but I can't believe it's ultimately sterile communities where people don't look out for their neighbors and people shooting up drugs on streets with a few rich hiding behind gated communities and controlling law makers. But maybe it is, maybe that is what we are about as a society. I like to think not.

Sorry for the rant, but this I believe is the root cause and until we solve it (somehow) the problem remains.

Avocado-related knife injuries: Describing an epidemic of hand injury (2020)
Can you offer any examples? When I think of the wealthy nations like the USA or UK, they mined and extracted much of their resources earlier than anyone. They just often did it in the less wealthy parts.
You are mixing up loans and deposits, which are entirely different.

Loans create money - nobody is disputing that. Deposits do not create or destroy money. Repaying a loan is not making a deposit.

Total deposits in banks, for example in the title "US banks lost $472 in deposits" is not calculated as the total deposits minus loans outstanding.

This sentence makes no sense and is incorrect:
>Money (deposits) are created at the point that loans are made.
