H100s can cost about $30k. There was an interview with a CEO in the space speculating that they have about 50,000 H100s. That's $1.5bn. Presumably they got volume discounts, though given the export bans they might have had to pay a premium on that discount to buy them secondhand. If it were H800s, that would be ~half the price, which is still high hundreds of millions for the chips alone.

Is that true? No idea. But there isn't zero evidence.
I've never done any drugs outside of alcohol, and I didn't do that until I was 21 and I never really drank that much even when I did.

I never smoked weed as a teenager because I had heard horror stories of people spiking illegal drugs with really horrible stuff. I have no idea if those stories were true, mostly likely they were exaggerated by law enforcement, but it worked to make me too much of a coward to try it.

Because I never smoked weed, I've grown a borderline-irrational hatred of it. It always felt like when my friends in high school started getting into weed, they would become insufferable pseudo-intellectuals who thought they were very deep because they watched a few Carl Sagan or Alan Watts videos. I hated how stupid it made my friends and I hated how it seemed to ruin their ability to remember things.

It's not clear how much of this is because of the weed, or just the fact that teenage boys are often just insufferable, by the way I remember it (which doesn't mean it's accurate) is that weed made all my friends in high school into pretentious morons.

I'm kind of glad that I never got into it now. I'm insufferable and pretentious enough as it is, I don't need chemicals to help with that.
I just don't think analogies to open source are useful in any direction. This is its own beast and we should just think about what we want out of it.

My understanding is that THC is primarily indirectly psychologically addictive. I should also add the irony that at least according to some, weed was pushed for bannage at least in part because it was something migrant farmers would use to help get through the simple monotonous work in their day [0].

To that extent it's not that different from the folks I worked with in many industries that had notable yet not directly debilitating habits in the gacha/lootbox, nicotine in one form or another, gambling, adult entertainers, expensive weekend trips, or whatever else happened to hit their dopamine receptors the right way due to past stimuli.

The bigger question is this; I've had colleagues that within a week of stopping work at a toxic place, stop drunk-dialing me at 2AM. Why aren't we asking that?

What are we not asking about cross-correlation? How many people go to darker paths to get their kicks? [1]

I think the issue most lay people have is that the host opening a door changes the odds of winning, because he knows where the prize is.

I think the easiest way to demonstrate that this is true is to play the same game with two doors, except the host doesn't open the other door if it has the prize behind it. This makes it obvious that the act of opening the door changes the probability of winning, because if the host opens the other door, you now have 100% chance of winning if you don't switch. Similarly, if they don't open the other door, you have a 0% chance of winning, and should switch. It's the fact that the host knows and chooses that is important.

It's only once you get over that initial hurdle that the 100 door game becomes "obvious". You know from the two door example that the answer isn't 50/50, and so the only answer that makes sense is that the probability mass gets concentrated in the other door.
I have plenty of anecdotes in the other direction. Perhaps there are other factors involved.

Weed isn't going to give you a leg up in life, but it's not a guarantee that you're going to end up in a dead end job and live with your parents forever either. Painting it as such reminds me of D.A.R.E.
I don't think this is possible. In a sufficiently large organization, however much you try to prevent it, some employees will be "psychopaths" (going by Hintjens's definition) looking to game the system. Whatever the metrics are, they will put in only enough effort to advance their own interests, and assuming they succeed (and at least some will) at getting raises/promotions, the org is then at risk of (legitimate) legal action from other employees who put in more actual work and get lower compensation.
By "tech" I'm sort of vaguely handwaving at Silicon Valley et al. I agree that China has built up a massive manufacturing industry that the west depends on, but I don't think that "being a significant cog in the machine," so to speak, buys as much influence or bargaining power as being the maker or owner of the machine. It's better to have the Apples and Googles of the world than it is to have the SG Micros or BYD Electronics.
Maybe cannabis users become efficient like MoE models, and they don't have to activate as many neurons at each inference step :)

It's actually the opposite. Calculating an asteroid impact is much easier because it primarily involves basic Newtonian physics. In contrast, the climate is a chaotic system, making long-term predictions far more complex.

True, but it would still be a very expensive inconvenience for SpaceX, I think enough that it isn't worth serving roaming users there and pissing off the countries.
Sam Harris has shared some similar thoughts about Musk: https://samharris.substack.com/p/the-trouble-with-elon

And here's an account of a woman who visited Auschwitz with him:

> I see people posting that Elon was at Auschwitz this time last year - therefore, his recent "gesture" is not antisemitic. I was there, too. Last year. With Elon. I am embarrassed that I have photos of this on my phone. My love, Gidon Lev, was the "special guest" of this photo-op event. We thought, at the time, that it would be good publicity. But I would not share the photo today. I chatted with Elon Musk. I spent hours with him and walked with him through Auschwitz. I stood with him, looking at the nauseating heaps of hair, luggage, and shoes flooded with violet light meant to preserve it. Is Musk an antisemite? People, actually, it's worse - he doesn't care whatsoever. Elon, father of "little X" as he described his freezing cold son to me, literally does not care. He was unmoved by the experience. For Gidon, to be in the place where his father, Ernst, died on a death march - whether shot by the side of the road or having simply collapsed - was a huge deal. Elon did not care. He was about his press junket and his bodyguards. I was ten feet from him as he posed for the cameras of his entourage. He was utterly detached. He cared about how he looked. When he placed a wreath at Auschwitz and Gidon was overlooked, he walked away with the cameras whirring. This is Elon Musk. A sociopath, if ever there was one. To deduce, from this visit, that he is a friend of the Jews is desperately naive.

Fewer, larger caps is probably correct for most hobby projects per this post, but many high-speed parts will recommend using tiny caps on the order of 1-10 nF underneath large BGAs plus some extra bulk capacitance (1-10 uF parts). It is really all about doing the math.

Because I was curious and had no idea about the relative size of meteors that hit the moon, the one that hit the moon in 2013 and was captured by Spanish astronomers was traveling at 65k KPH and weighed about 400kg. That had an impact energy of 15 tons of TNT (https://www.youtube.com/watch?v=perqv4qByaI&t=1s)

Safe to say, an 8 megaton impact from one that weighs 220,000,000kg would be a bit more substantial! Apparently that would be roughly the size of the Meteor Crater in Arizona (https://en.wikipedia.org/wiki/Meteor_Crater).
It still doesn't make sense to me. If the money for training is still there, wouldn't companies that can afford it use the efficiency gains and also scale up models?

hey, creator of spreadsheets-are-all-you-need.ai here. Thanks for mentioning!

I now have a web version of GPT2 implemented in pure JavaScript for web developers at https://spreadsheets-are-all-you-need.ai/gpt2/.

The best part is that you can debug and step through it in the browser dev tools: https://youtube.com/watch?v=cXKJJEzIGy4 (100 second demo). Every single step is is in plain vanilla client side JavaScript (even the matrix multiplications). You don't need python, etc. Heck, you don't even have to leave your browser.

I recently did an updated version of my talk with it for JavaScript developers here: https://youtube.com/watch?v=siGKUyTk9M0 (52 min). That should give you a basic grounding on what's happening inside a Transformer.
To me, AI is something that learns or adapts how to perform a task, without being explicitly given instructions on it. I've almost always seen this definition used in this manner.

Something beyond human intelligence is also AI, just maybe a subset of general AI or strong AI (as opposed to narrow or weak AI).
Do you have a good theoretical foundation in ML ? You will also need some linear algebra.

If not would invest the time in a decent course, there are plenty online, even offline if you are close enough to where its offered. I took one from Andrew Ng on Coursera years ago, which used Matlab. There are probably much better, more up-to-date options now, especially now that LLMs are very in-vogue. The fundamentals such as gradient descent, ANNs and back-propagation however, is still relevant, and hasn't changed much.

Trying to understand what code is doing without that foundation will be an exercise in futility.

As opposed to data? What data?
Imagine how hard this is to study:

- can we identify groups who regularly use and don’t use
- and isolate other lifestyle factors
- and follow them for years of the life
- and get them to accurately report data
- and determine which life outcomes can be attributed to cannabis use

No study like that is going to be compelling. The anecdote is going to be just as useful in your personal life. It’s how humans learn.

> the ACA is popular.

It's more popular than nothing, of course. I wouldn't trade it for nothing either.

> Its popularity is growing.

This is somewhat misleading. Over the years, its polling has gone up and down within a range. https://news.gallup.com/poll/654101/health-coverage-governme...

> Passing the ACA was a matter of getting half a loaf rather than none. It was an attempt to do something.

This is the kind of Sophie's Choice I hate. Single-payer health care was proposed in the US in the 1970s but was killed by Jimmy Carter, inspiring Ted Kennedy to primary challenge him. We could have had it, and still could have it.

Polling doesn't tell the whole story, because single-payer was taken off the table for decades. It wasn't part of the public debate, because hardly any political leaders advocated for it, not even Democrats. Bernie Sanders, a socialist, almost single-handedly resuscitated single-payer. Regardless of the polling, single-payer is demonstrably superior, as shown by nearly every developed country in the world besides the United States. The reason we don't have it is massive corruption, the health care industry buying off opposition. Buying Democrats as well as Republicans.

> "the Democrats are as bad as a Republicans"

I didn't say that. I said they're both corrupt.

> They succeeded at it and then struggled in the next two elections, and arguably the third as well.

Third? What third? Dobbs was decided in 2022. To say that Republicans "struggled" seems like an overstatement. Perhaps they won fewer seats in Congress than they could have, but they still took control of the House in 2022, adding the Senate and Presidency in 2024. If only Democrats experienced such a "struggle".

> My point was that when they take the power they have won and attempt to enact their policy positions they start losing. This was an example of that.

Republicans gained full control of the federal government a mere two years after Dobbs. That's winning, not losing.

This kind of double-speak is so annoying.

"To be clear, the goal here is not to deny China or any other authoritarian country the immense benefits in science, medicine, quality of life, and so on that come from very powerful AI systems. Everyone should be able to benefit from AI. The goal is to prevent them from gaining military dominance.”

A moralizing statement that weasels out of the implication.

This would be a more straightforward way to say it: Export restrictions are necessary to prevent China from gaining military dominance, even if those restrictions deny China the immense benefits in science, medicine, quality of life, and so on that come from very powerful AI systems.

You can’t understand the journalism problem until you face that it has always been propaganda and PR. We just didn’t know how bad it was until we had alternative sources.

Ha. You’re right about that. Coffee can create some weird heart issues, so I think you’re right.
I observe the same thing, but I think in a lot of towns and schools, like yours and mine, the kids who chose to smoke weed were the ones who saw themselves as unmotivated losers and screwups. The connection could have been a self-fulfilling prophecy.

I think there are enough places like that to skew any study that doesn't somehow control for it. It would be interesting to see if the result holds for kids who didn't see themselves that way, kids who are bright and ambitious or even just average, or if it only holds for kids who already saw themselves as underachievers before they started getting high.
Very very different weed.
I seriously don't know why this is making rounds on HN as if it were some revelation.

It should be pretty obvious that messing with your brain circutry in such an overt manner leads to various unintended consequences, just like every other vice (yes even "benign" things like social media or video game addiction).
1% is tiny, really small.

In my experience, commonly orbits in the solar system are astoundingly accurate over centuries. This prediction is relatively soon, 2032.

So, we have (A) a crude orbit and only 1% prediction of hitting Earth or (B) an accurate prediction of 100% = 1. Between these two, (A) seemed too small and (B) too large. So, I asked.

This question seemed appropriate enough.

Reading the paper, sure, they have a lot of predictions for several decades to come with all the probabilities close to 1% and far from 100%. The paper gives some details on the difficulty of getting a very accurate orbit for the object. So, apparently the 1% is what they have in mind and their title, accurate.

So, if it hits, what might be the damage?

And it it does hit, what would be the probability of it hitting a densely populated area instead of ocean, desert, mountains, ...? Net, with the 1%, the risk of major damage seems quite small.

Hmm, what would the insurance industry think? Vegas?
Well, the vibe I'm getting from these comments is people reacting emotionally, and assuming the study concludes that smoking cannabis causes memory problems. But the article itself says:

> The study has limitations. It was an uncontrolled, cross-sectional study, so the association seen between cannabis and brain function can’t be considered causal.

So even this study doesn't say it's causal, and admits to many other limitations. I agree with your point about evidence and science though, but this is hardly a smoking gun that cannabis makes you dumber.
As a disclaimer, I generally dislike most managed offerings of anything, because I don’t think you get nearly the value out of them for the price hike (and performance drop). For DBs especially, I don’t see the value, but I’m also a DBRE with extensive Linux experience, so the maintenance side doesn’t bother me.

For Aurora in general, here’s a short list:

* Since the storage is separated, and farther than even EBS, latency is worse. Local, on-hardware NVMe is blindingly fast, enough that you can often forget that it isn’t RAM.

* I’ve yet to see Aurora perform better; MySQL or Postgres variants. My 13 year old Dell R620s literally outperform them; I’ve tested it.

* The claimed benefit of being able to take a DB up to 128 TiB is a. an artificial limit that they’ve made worse by denying the same to RDS b. difficult to reach in practice, because of a bunch of gotchas like fixed-size temporary storage, which can make it impossible to do online DDL of large tables.

* For the MySQL variant, they removed the change buffer entirely (since storage is distributed, it was necessary for their design), which dramatically slows down writes to tables with secondary indices.

* It’s not open-source. I can and have pored through Postgres and MySQL source code, built debug builds, etc. to figure out why something was happening.
