Looking at the top 1000 I'm surprised there's no power law. It's just a lot of people with generally similar number of words.

rocqua · 5 days ago

Feels quite power-law like to me, but checking this roughly it seems to decay more quickly than a power law, but with a fatter tail. At least in the top 1000

The top 3 with 4,000,000 words have about 20 times as many words that the 0.14% percentile (at rank 1000) with 200,000 words.

In between (at rank 500) your at about 450,000 words, so its not a true power law. Because a drop of a factor 9 per 500 ranks would suggest that rank 1000 were at about 50000 words.

>Getting rid of the copious amounts of heat that data centers generate might also be a challenge

at 70 Celsius - normal for GPU - 1.5m2 radiates something like 1KWt (which requires 4m2 of panels to collect), so doesn't look to a be an issue. (some look to ISS which is a bad example - the ISS needs 20 Celsius, and black body radiation is T^4)

rocqua · 5 days ago

So for the ISS at 20c you'd get 481 W/m^2 so you'd only need 2.3m2. So comparing the ISS at 20c to space datacenters at 70c you get an improvement of 63%. Nice, but doesn't feel game-changing.

The power radiated is T^4, but 70c is only about 17.1% warmer than 20c because you need to compare in kelvin.

> This makes no sense. Buybacks and dividends are how companies give money to investors

Dividends are totally fine (from my perspective), while. buybacks are problematic from a place where executives are bonused on share price and earnings per share, both of which can be manipulated by buybacks.

More philosophically, I think that dividends are better for society as they allow investors to realise a stream of value from well run companies rather than needing to sell their share to acquire this value.

This is obviously just my opinion though, I don't know if it matches to what the OP cares about.

rocqua · 11 days ago

Why does it matter if people have to sell their shares to unlock value? Is it just the friction of small orders?

Buybacks for manipulating share prices and earnings per share are indeed silly. But they should also be trivial to compensate for by normalising on market cap instead of a single share.

> ASML also announced a new share buyback programme of up to €12 billion, to be executed by 31 December 2028.

Oh boy. This fills me with dread. I've never seen a company that starts doing buybacks not become a financialized hollow shell within a decade. Being an irreplaceable monopoly on the commanding heights of the digital economy makes this even worse.

rocqua · 11 days ago

A buyback is almost the same as a dividend, with minor differences around tax and effects on derivative pricing.

And ASML has been paying out a dividend for a long time.

If tech companies implemented real, e2e encryption for all user data, there would be a huge outcry, as the most notable effect would be lots of people losing access to their data irrevocably.

I'm all for criticizing tech companies but it's pointless to demand the impossible.

Just say "we are storing your keys on our servers so you won't lose them" and follow that with either "do you trust us" or even "we will share this key with law enforcement if compelled". Would be fine. Let people make these decisions.

Besides, bit ocker keys are really quite hard to lose.

I find that the LLMs are good at the 'glue code'. The "here's a rather simple CRUD like program, please tie all of the important things together in the right way". That was always a rather important and challenging bit of work, so having LLMs take it of our hands is valuable.

But for the code where the hard part isn't making things designed separately work together, but getting the actual algorithm right. That's where I find LLMs still really fail. Finding that trick to take your approach from quadratic to N log N, or even just understanding what you mean after you found the trick yourself. I've had little luck there with LLMs.

I think this is mostly great, because its the hard stuff that I have always found fun. Properly architecting these CRUD apps, and learning which out of the infinite set of ways to do this are better, was fun as a matter of craftsmanship. But that hits at a different level from implementing a cool new algorithm.

So he explains OFDM in a way that implicitly does Amplitude shift keying.

I guess if you want to use different modulations you treat the complex number corresponding to the subcarrier as an IQ point in quadrature. So you take the same symbols, but read them off in the frequency domain instead of the time domain.

And I guess this works out quite equivalently to normally modulating these symbols at properly offset frequencies (just by the superposition principle)

> It is embarrassing to restrict an open source tool that is (IMO) a strictly and very superior piece of software from using your model.

> Shutting down the other tool, if that's what's in fact happening, is what is embarrassing.

To rephrase it different as I feel my question didn't land. It's clear to me that you think it's embarrassing. And it's clear what you think is embarrassing. I'm trying to understand why you think it's embarrassing. I don't think it is at all.

Your statements above are simply saying "X is embarrassing because it's embarrassing". Yes I hear that you think it's embarrassing but I don't think it is at all. Do you have a reason you can give why you think it's embarrassing? I think it's very wise and pretty standard to not subsidize people who aren't using your tool.

I'm willing to consider arguments differently, but I'm not hearing one. Other than "it just is because it is".

rocqua · a month ago

If your value proposition is: do X, and then you have to take action against an open source competitor for doing X better, that shows that you were beaten at the thing you tried very hard at, by people with way fewer resources.

I can see why you would call that embarrassing.

This is damn impressive. I suppose all the makers of military drones are lining up at the factory already. I mean, electric bikes are fine, but who has the most burning need to increase range and payload?..

rocqua · a month ago

Sorry to hijavk, but why are drones still on electric power? I'd expect some kind of air breathing engine to be manufacturable at low cost if it only has to function for a single flight. Especially for interceptor drones the speed is valuable. But for all types of drones the extra range is also highly valuable.

Age: 22+-3 AND with that weight to ffbm ratio not only untrained, but at least slightly (I’m being generous here) overweight.

With these pre-requisites it almost doesn’t matter what kind of physical activity one does- the muscles will grow anyway. It’s when you are older and/or accustomed to some kind of physical training, that you really noticeably benefit from resistance training.

And still, that ‘almost’ part does a lot of the heavy lifting here. I don’t believe it’s really possible for a couch potato without any experience to correctly assess their 1RM. People with no experience with pain and effort typically can’t push themselves hard enough, so the entire exercise turns to a half-cardio anyway.

And gauging 1 rep max in a bicep curl is especially difficult (saying nothing of a risk of injury).

I understand the complexity and difficulty of researching the subject, but this entire article is no good and is hardly applicable to most of the population IMO

Are you perhaps reading a personal advice in a paper, disliking the advice, and then finding that due to the experimental design, it doesn't work on you. And then, rather than concluding the paper didn't intend to inform your personal routine, instead conclude that the paper was badly designed? Or to put it differently. Have you considered how many people live in a way you would never consider close to acceptable?

Because your points make sense but it feels like you are arguing against a bit of a strawman, or arguing for a mostly ideal situation rather than current reality?

For overweight and understrength people, is it not very valuable to know that they don't need the extra steps of resistance training to see real improvement in strength and fitness?
