I think the other issue is that "crypto" is not "money". There is no card I can carry that I can take to an ATM and convert crypto to money knowing before I left my house that day exactly how much I would get down to the penny.

Crypto has value the way Gold or pawnable items do, and until that barrier has been crossed the people will never embrace crypto as an alternative to cash and credit.

Realistically the only way for that to happen would be if the US replaced their currency with a government backed crypto, but that is unlikely to happen without a coup.

Visa and MC could still offer lines of credit in such a system but they would not be the primary purveyors of capital motility and therefore their entire business model would collapse or require extensive restructuring.

Great feedback, thank you. The video is indeed on the landing page, but as people have mentioned it's hard to see (which is obviously a problem hahah).

I am working on putting out more videos! Definitely aiming to address the accuracy and answer some other FAQ. As far as 3D printed parts go, tbh I'm just going that route for now because it's easier. Less hassle to deal with another manufacturer (or build out my own print farm, which is a whole other thing) and have to go through all the quality control that comes with that. Definitely planning on incorporating 3DP parts in the future, but saving that for when other stuff is more dialed in. Good idea to include a link to 3DP supplier.

Huh? "Both" sides? I didn't even think about any sides, much less specifically two of them. My comment wasn't even necessarily about online discussions concerning politics. It was just as much about, for example, the way people show off their fake-successful influencer-lifestyle or something like that. The ways that social media causes bad feelings like jealousy, for example.

> I know some people who went into the air force out of high school. They are idiots

Every population has some idiots in it. My point is the Air Force is difficult to get into, has a high fraction of educated servicemembers [1], has lower turnover and higher pay than the other branches. (Back when we measured IQ, the Air Force had a higher average IQ than the other branches and population.)

I know idiots who work at Google. That doesn't it's safe to assume the average person at Google is an idiot.

That's just your bank giving back some (but not all) of those 2+% interchange fees.

Basically, in EU you have low fees, so credit cards are boring, they offer almost zero perks (because there's no money to finance those). No one really cares about what brand of card they get, only about their credit limit. In the US you are charged high fees on every purchase, and then the bank uses your own money to bribe you, or encourage particular types of (excessive) spending, or just make you addicted to credit card debt.

Two things.

First, please correct me if I'm wrong, but is it possible that the article made a mistake either in the dosages or the substance that was administered? It calls 5mg/kg of psilocybin a low dose. To me, this is an insanely high amount if we're really talking pure psilocybin (not psilocybin mushrooms). Johns Hopkins reported treating people with (high) therapeutic doses of psilocybin (not mushrooms) of between 20mg and 30mg per 70kg. In strictly mushroom weight, that's anything between 3g and 5g of dried cubensis. If the article is correct, what they administer those mice is the equivalent of giving a 70kg human 350mg of psilocybin (as a low dose lol), or about 50g-60g of dried mushrooms to munch on? I hope the article made a mistake, rather than someone from the research team misread the recommended dosage.

EDIT: According to my limited search, a 12-weeks old lab rat could weight anything between 0.25-0.5kg. At 5mg-15mg/kg, that's approximately 1.25-2.50mg for low doses of psilocybin and 3.75-7.5mg for high doses. I don't find this as outrageous as originally. It could work if we take into consideration that brain size is probably a more significant factor than body mass.

Second.

> this study suggests that psilocybin impacts multiple hallmarks of aging by reducing oxidative stress, improving DNA repair responses, and preserving telomere length. Telomeres are the structured ends of a chromosome, protecting it from damage that could lead to the formation of age-related diseases, such as cancer, neurodegeneration or cardiovascular disease. These foundational processes influence human aging and the onset of these chronic diseases.

Unless I misunderstand what I'm reading, I wouldn't say that it's really psilocybin (the chemical) that's responsible. It's the taking then subsequent tripping. It's now known that without the trip, no benefit. If my intuition is correct, it could be that LSD along with a few other psychedelics (and associated practices) might affect you in a similar way over the long run.

What’s happening in MMA and boxing isn’t growth, it’s consolidation. TKO is lobbying for legislation that rewrites boxing’s foundation. UFC’s planting a cage on the White House lawn. PFL signs Dakota Ditcheva but still lacks real challengers. This isn’t innovation. It’s manipulation.

The media won’t touch it because they’re all bought in or blacklisted. I’ve laid out the moves, the motives, and the money trail in this piece. Would love to hear your take. Is this just where combat sports is headed, or is this the slow death of meritocracy?

The best VRAM calculator I have found is https://apxml.com/tools/vram-calculator. It is much more thorough than this one. For example, it understands different models' attention schemes for correct KV cache size calculation, and supports quantization of both the model and the KV cache. Also, fine-tuning. It has its own limitations, such as only supporting specific models. In practice though, the generic calculators are not very useful because model architectures vary (mainly the KV cache) and end up being way off. (Not sure whether or not it would be better to discuss it separately, but I submitted it at https://news.ycombinator.com/item?id=44677409)

NVidia is a great company, with a phenomenal product that they competently developed and made dominant. There was a big element of luck in that, but it won't continue forever no matter how smart and diligent they are.

It feels like the whole magnificent seven thing and the the way they are holding up an overvalued stock market is driving some desperate decision-making. Like 12 more billion dollars for XAI to buy more Nvidia GPUs does XAI have any revenue at all?

Every serious study of this was done by people entirely aware of that problem, who use multiple data sources to mitigate the effect. And yet every time this comes up on HN a bunch of posters are all “well I push buttons on keyboards for a living, so I know better than experts in every other field, even about their own field!”

I’ve seen posters complaining about unreported crimes on here in response to posts citing studies that directly and prominently address that exact problem, because I guess they just assume everyone in the social sciences is a total dipshit who can’t possibly have thought of this obvious thing (and didn’t bother to read the study and perhaps learn something).

Victimization surveys agree with police report data. Crime’s down in general, way down in some cities, and violent crime especially is down, versus the 90s, and very much so versus any decade before that. There’s been a little bump post-Covid but it’s not ongoing and last I checked it was trending back down again, and it wasn’t anywhere near wiping out the progress from before.

Hard to say with 100% certainty without a human trial, but the short answer is "probably not." This is a situation where a person has three copies of chromosome 21 in every cell. Shutting one copy down would, hypothetically, leave someone with two working copies. I don't think we have any reason to believe that trisomy is masking some other phenomenon that we won't see until a fetus with this treatment applied fully develops into a newborn.

(And that's of course assuming human trials were authorized. Probably not for this treatment in my lifetime, at least not in the US).

> North Korea is targeted because it is a socialist

You've got to be kidding me.

America has a Gini coefficient of about .42 [1]. The last time North Korea's was estimated, it was around .82. To to put that in perspective, the inequality gap between America and North Korea is well more than double that between America and the Netherlands.

Go lang will happily use multiple cores if the load calls for it, multiple cores are available, and GOMAXPROCS is not restricted to 1.

With Python's asyncio, yes, you can read from many client sockets in a core, but you really can't do much work with them in the core, otherwise even the IO will slow down. It is not future-proof at all.

There’s a good argument for not “leaving it to the market” for things like this: when you’re evaluating an apartment (to rent, or even to buy), it can be difficult to know what the soundproofing is like. Noise is maybe not life and death, but it’s a major quality of life issue for some people.

Of course an outright ban is pretty extreme, but alternatives to overcoming this information asymmetry are not straightforward. Ideally: compulsory testing and disclosure, if it could be done.

This dichotomy is obviously false though.

If an attacker doesn't have a firearm you probably have time to chamber a round, if the attacker misses a shot at you you have time to chamber a round, if you have time to take cover you may have time to chamber a round and then be in an approximately 50-50 situation, etc.

> There seems to be significant opportunity to zig as others zag. Imagine the Intel letter saying "we are going to take advantage of the current hiring environment to scoop up talent, and push forward on initiatives."

I've pitched that a couple times in my career. The difficulty is that, in a lot of cases, your future business prospects are genuinely correlated with the future prospects of other businesses.

Intel is going to sell fewer CPUs in the next 3 years if other businesses aren't hiring and expanding as quickly as they did during COVID. And I think there's a pretty good reason to think that Intel's revenues will actually shrink as a result.

That limits how much zig they can do while others zag.

Gemini is apparently doing pretty well. 400 monthly active users on their app and they recently increased the prices for their API.

Sundar Pichai has taken a lot of heat in the past couple years (and for good reason) but distribution is one of his main strengths. Now that they are back to being SOTA on the models, they can fallback on their bread and butter.

I think ChatGPT is still going to be a major player considering the amount of mindshare they have but I tend to fall on the side that thinks there's room for multiple players in the AI game.

It happens all the time sadly.

It's not because people intentionally write this way. A function takes a parameter (a Go slice for example) and calls another function and so one. Deep down a function copies the pointer to the slice (via closure for example). And then a goroutine is spawned with this closure.

The most obvious mistakes are caught quickly. Buu sharing a memory address between two threads can happen very indirectly.

And somehow in Go, everybody feels incredibly comfortable spawning millions of coroutines/threads.

It's from my 7th grade history teacher, Mr. Mooneyham. As in "tomorrow we're going to cuss and discuss the Louisiana Purchase. Make sure you read chapter 12." He was also the teacher who had the "Super-Duper Discussion Stick" which he used to hit your desk if you fell asleep in class. And at least once he played the version of the "Devil Went Down to Georgia" w/ the bad words left in.

In the old days, public schools in suburban Texas were quirky, but the quality of education was relatively decent. For instance, I remember that Thomas Jefferson was president in 1803 when the Louisiana Purchase was finalized.

I am using an HTTP generator, yy025, plus a TCP client, not FF, Safari or Chrome. The HTTP generator is written by me.

The TCP client is typically Al Walker's original netcat, djb's tcpclient or haproxy's tcploop (modified). But any TCP client will work.

I generally use haproxy and tinyproxy-stunnel as TLS forward proxies. The former lets me monitor all HTTPS traffic from computers I own over the the network I own and modify headers, cookies, URLs, response bodies, prevent SNI, etc. (Most use haproxy as a reverse proxy.)

I do not make remote DNS queries immediately followed by associated HTTP requests. They are separeted in time. The DNS data is gathered in bulk from varied sources periodically. I do this with software tools I wrote myself that are designed for HTTP/1.1 pipelining. The domain-to-IP mappings are stored in the proxy's memory. There are no remote DNS requests when I make HTTP requests.

I use a modified text-only browsser as an HTML reader. It does not auto-loead resources, process CSS or run Javascript.

I do text processing on bulk HTML and DNS data, e.g., from HTTP/1.1 pipelining, with custom filters I wrote myself to produce SQL, CSV and other formats.

This is only a sample of things I do differently according own specific preferences.

The so-called modern browsers cannot do all of these things in combination, as separate programs. In some cases, e.g., HTTP/1.1 pipelining, real-time monitoring of HTTPS traffic in plaintext, even something as simple as preventing SNI from being sent, these browsers cannot do them at all, even with extensions. The so-called "modern" browsers are enormous by comparison and ridiculously complicated. They are distributed by corporations invested heavily in online ads.

Perhaps the most important difference is that I can compile each of the software tools I use in minutes, in most cases less than one minute. I can easily edit the source code in an edit-compile-test loop to address issues that arise and to suit personal preferences. This is not feasible with the so-called "modern" web browsers. Trying to compile these so-called "modern" browsers from source is excruciatingly slow. I can compile UNIX kernels with complete userlands, an entire OS, faster, easier and with only minimal resources (CPU, memory, storage).

You understand it correctly: it doesn’t remove any value from fixup; instead it just means you can fixup to whatever and move the commit visually to where you want it — doesn’t have to be the main/trunk branch, and you can do it whenever is convenient.

That’s where I made the comment about not actually running fixup. Instead of claiming to fix a SHA, I leave myself a note like “fix tests” so I can move it appropriately even if I get distracted for a few days

> targeted specifically high ticket items (jewelry, luxury)

My immediate instinct upon reading this is "of course those businesses wouldn't be interested". They are selling a brand and image first, and if it looked like they wanted people to download some new app and put in their bank details to make a purchase instead of swiping a credit card it would cheapen the brand. Luxury stores are all about a streamlined experience and the appearance that money is no issue.

>That's just your bank giving back some (but not all) of those 2% interchange fees.

On the contrary, for someone like me who pays off my balances each month, if I get 2% back for every transaction, I am breaking even on those fees if assuming that I pay 100% of the fees, which of course isn't true; the merchant pays some of that. So really, I come out slightly ahead.

For something like the Amex I mentioned with its 5% back on Amazon, I am coming out well ahead.

> and then the bank uses your own money to bribe you, or encourage particular types of (excessive) spending, or just make you addicted to credit card debt.

Oh, good grief. So EU credit card companies don't do this? I had no idea they offered cards purely as a charitable venture.

In general the safety rules I was taught were defense in depth -- multiple failures need to happen before someone can get hurt. So, even when you have a holstered firearm, pointing the muzzle away from people is preferable because then if it somehow does fail at least it's less likely to shoot someone.

Obviously that's not always practical, but if you are placing a chambered firearm down on a desk, you might as well try to point it in the direction of least harm, it basically costs zero to do.

It's the bitrate we used to have before they made it a premium plus all star plus+ feature and downgraded the rest.

Netflix did the same. In fact they even silently downgraded us from 4k HDR surround sound during a software update. And nothing can get us back the max quality anymore. I stopped paying all together.

So you know what doesn't buffer, has the absolute best quality (like 4x the bitrate etc), all the languages and what not? pirated content.

It's just stupid how much easier it is to obtain predictable quality without stutter by downloading rather than actually paying a streamer service.

Plus the ads and other UX dark patterns are through the roof.

Also former fat guy here. I absolutely have not had that experience. I have easily maintained being fat (or even gained) while running 15-20k a week and walking everywhere. It's only when I actively moderate my eating have I lost weight. Otherwise I'd just slam down Oreos or whatever. It's stupid easy to get unfilling high calorie food.

To learn that we went to war with North Korea because it's communist? No shit. We also did that with Russia, China, Vietnam and a good fraction of current NATO members, trade partners and allies.

> Did you really think anticommunism disappeared from American elites?

Elites? Most Americans have unfavourable views of communism [1].

But you didn't say communism. You said socialism. And it's a bit ridiculous to argue (a) North Korea is run as a socialist economy or (b) that we have a beef with Pyongyang, today, because of how it runs its economy.

It says that they've developed a way to identify the extra chromosome(s) passed to a child by a malfunctioning germ cell, specifically chromosome 21 though presumably this method could be reproduced for other trisomy diseases. This could, most immediately, lead to a therapy that allows a couple that is going through in vitro fertilization to repair a zygote that has trisomy by correcting the number of chromosomes it has, and preventing the resulting child from having Down's syndrome. This is relevant especially for older mothers, who are most likely to produce malfunctioning eggs that result in Down's syndrome

There's none.

RISC-V is inevitable.

Intel will simply miss the train, and go under.

Unlike Intel, AMD isn't clueless. After Zen6, it will likely release good RISC-V chips with some sort of x86 acceleration for unprivileged code as selling point, remaining relevant and securing themselves market share during the (inevitable) transition.

> So EU credit card companies don't do this?

No, as I said, they don't because of the interchange fees limit: they simply don't have money to finance any perks. Sometimes you get travel insurance, with the card that charges 200 EUR annual fee, sometimes you get some rewards program, where you collect the points, but those points are typically valued at 0.0001 cent, so no one really bothers earning them. Credit cards in Europe are really boring, commodity products, not status symbols or coupon books.

You are paying that one way or the other: merchant will pass their fees on you by raising prices.

It's not efficient if you need 100,000 threads. 1,000 threads are almost free... what's expensive is thread switching in cases where parallelism matters. I have pair programmed embarrassingly parallel problems so many times and every time my partner wanted to argue about the need to batch the work and every time we failed to get a speedup the first time, and after adding batching we got close to ideal speedup.

People are still hung up on this 1999 article

https://www.kegel.com/c10k.html

but hardware has moved on. I'm typing this on a machine with 16 CPU cores and I'm more worried about leaving easy parallelism on the table (even when it only gets say a 40% overall speedup) more than I am in 5% overhead from OS threads. I've seen so much buggy code that tries to get it correct with select() and io_uring() and all that but doesn't quite. Google has to handle enough questions to care, and you probably don't. If you worry about these things (right or wrong) Java has your back with virtual threads.
