Intermittent renewables such as wind and solar do not work fine alone, as they are non-dispatchable.

https://en.wikipedia.org/wiki/Dispatchable_generation

They are OK as an addition to dispatchable sources, which is why the vast majority of industrialized nations are now planning for a mix of nuclear and intermittent renewables.
Nobody sane hates you, personally or collectively.

But we can definitely dislike certain aspects of certain cultures, especially since in this case that culture is the most massively exported culture in the history of mankind.

Of course the gp comment is out of place and taste.
> It's a false dichotomy.

It's not. Without nuclear scare the developed world electricity mix could have look like France's as early as the 90s, saving countless tons of CO2 emissions, and millions of lifes. Renewable are eventually coming but the tech took 40 more years to come, and that's how much we're late.
Thanks for pointing me to Pebblebee. Recommend trying it out?
The thing is, calculating a competitive (aka global maximum) general equilibrium is NP hard if the economy contains non divisible elements. This doesn't necessarily prevent us from being in an equilibrium, but it certainly makes it highly unlikely that we are in the best equilibrium.
Monkeys who've trained since birth to use sign language, and can reply incredible questions, have the same issue. The researchers noticed they never once asked a question like "why is the sky blue?" or "why do you dress up". Zero initiating conversation, but they do reply when you ask what they want.

My new PC arrives tomorrow. Once I source myself two RTX 3060's I'll be an AI owner, no longer dependant on cloud APIs.

Currently the bottleneck is Agents. If you want a large language model to actually do anything you need an Agent. Agents so far need a human in the loop to keep them sane. Until that problem is solved most human jobs are still safe.

They are?

Supercapacitors have been around for decades and they store an order of magnitude or two less energy than batteries.

And a battery that runs at 5C isn't new either.

There are some devices that kind of do both internally, but this isn't one of them.

Too bad. It looks a lot like these real direct drive motors.[1] Those are in the same price range, and could get much cheaper if produced in quantity.
The nice thing about direct drive motor robots is that you can't strip the teeth of a magnetic field. Impact forces are not a big problem. Robot gear trains are usually the weak point.

From computer science, read the title of the paper “attention is all you need” ;)

That's easy to say, but it's a trillion-dollar decision. Alphabet and Meta are both worthless in that scenario, because ~all of their revenue comes from connecting unfamiliar sellers with buyers. Amazon is at existential risk. The collapse of Alibaba would have a devastating impact on Chinese exporters, with massive consequent geopolitical risks.

Nature had been doing that for billions of years until a few decades ago when we were told "progress" meant we had to stop doing the same thing more peacefully and intentionally.

My guess is the future belongs to those who don't stop—who, in fact, embrace the opposite of stopping.

I would even suggest that the present belongs to those who didn't stop. It may be too late for normal people to ever catch up by the time we realize the trick that was played on us.

Ask HN: Who feels depressed after yet another Chat GPT announcement?
Is it just me who feels gloomy and depressed after yet another Chat GPT announcement?

It feels like life is throwing you overboard. You continue to work by inertia on legacy code that was written very poorly. The company is not ready to use AI (idiots), life is passing by.

People don't realize what a Pandora's box we've opened. There's one last step left. In 5-10 years, we will saturate our world with external manipulators through which AI will be able to control the world.

A universal basic income is already being fully discussed by the elites, as the scale of “layoffs” becomes clearer. Millions of people will simply become useless soon.

As an engineer, I partly feel guilty about this. As a result, we, engineers, came up with a system that will eventually replace even us and we will become commodities in the next 10-15 years.

What do you HN community think about this?
Monads are easy. They're just a design pattern that provides a formal abstraction over operation sequencing with additional computation. If you just accept them as they are, rather than attempting to grok them by approaching them by analogy ("monads are like burritos"), you will make your life much easier.

That's the secret to Haskell. There's no "getting it". There's just using it.

proliferation is a real concern but this part is completely ill-founded

> including many private entities (Elon Musk for sure but quite probably, many much smaller ones, plus churches as well)

Modern (that is since the end of the middle ages) State exists because they enforce the “monopoly of violence”, there's no way any private individual could be allowed to have nukes. Even in Russia, the realm of Oligarchs' PMCs (well before Prigojin assassination) the State always maintained full control on its nukes (and when Russia was a failed state at the beginning of the 90s, the US worked hard to make sure it was the case). Private entities with nukes could only happen in the event of a complete collapse of the US as a State, in which case nuclear proliferation would be the least of your problems (and even then, I don't see China not intervening to stop that from happening anyway, like the US did in Russia)

Imagine a humanoid robot that is comparable to your average joe in terms of dexterity and stamina like let's say as a high water mark it can rebuild a car engine and do basic dentistry for sixteen hours of the day as long as it recharges for the other eight. Let's say that it has the ability to carry a robot of equal weight about 25 km and can repair that fellow robot provided that it has the necessary parts and a basic tool set and the equivalent to your average residential garage type environment to work in[0] (but like really could do it in the field).

If you had a pair of two of these robots and your run of the mill warehouse full of their spare parts (assume a tape of infinite length...) so that with careful planning between the two of them they could do the necessary preventative maintenance on each other so that they didn't break down at the same time, or could go rescue the other if it broke down unexpectedly in the field, how long would it take them to build the infrastructure necessary to produce new parts to replenish their stockpile and generate new robots so that they could experience exponential growth?

When I watch stuff like Primitive Technology[1] I'm in awe at how asingle well-fed and educated human being can with the right preparation and research can go into a jungle setting and speed run up to the iron age. It makes me wonder about the minimum viable number of people and education/knowledge/experience required to do the same thing for realsies to the computer age. It's just a pipe dream or two about when a robot equivalent to the average joe is a thing and when I see videos like the one we're talking about or the recent one from Boston Dynamics the gears in my mind start turning.

There was a time when computers didn't exist. Then they did. At first computers used to be the size of buildings, then they became the size of floors of buildings, then the size of rooms, then the size of appliances[2], and so on and so forth. we're seeing this sort of miniaturization across segments of industry driven in large part by the miniaturization of semiconductors. If you take a big picture view the economy as a whole it is a self replicating machine. As are the vertiable Adam and Eve that made that economy. In a complicated sort of orobourous way the entire economy is made up of humanoids (and let's not forget our quadroped hoven friends who serve as feedstock btw, or chickens and tuna and so on...) who replicate in some way or another.

There is this sort of impending collision between the organic and inorganic self replicating aspects of our economic system. Ribozyme and hominid, compiler and automobile assembly line, what are the difference exactly?

Nvidia has about a hundred direct competitors in AI accelerator space, both in datacenters and in edge devices. Apple is typically only interested in edge devices. Mac servers, despite the name, are edge devices. It is possible that Apple decides to make their own datacenter chips but I don’t really see it. It’s not their area of expertise. Even Amazon struggles pushing their AI chips, no one wants them.
That means your strategy is to make some assumptions about where your marketing will be well received, and insist on only showing it there.

This limits you to the quality of your assumptions. It's always going to be better to show your marketing where it actually works than to show it where you believe it works.

I think the core thing that ORMs do is create a 1:1 mapping between the data structures in the database (that are, or should be, optimised for storage) and the data structures in the application (that are, or should be, optimised for the application business logic).

ORMs create this false equivalence (and in this sense, so does Django's admin interface despite using tuples instead of classes). I can see the sense of this, vaguely, for an admin interface, but it's still a false equivalence.

> You will run into energy issues very fast with this as soon as you do anything reasonable with it.

Our goal is specifically to research how to accomplish farming in our roughly 1kw work envelope. I personally believe this is achievable, it just takes a different approach to tools. We will build new custom tools for this. One thing to note is that since the vehicle is autonomous (there is no driver) it can move very slowly if this helps conserve energy. Tractors traditionally use a lot of power to save the driver's time, which is not a constraint for us.

> Like removing weeds, watering, fertilize, ...

I don't see why removing weeds would require more than 1kw. Watering is usually done with fixed pipes laid at the start of the season, rather than machines driving around transporting water. Fertilizing again doesn't require much energy. Our vehicle only draws 60-100 watts while driving on level ground. That leaves plenty of energy for distributing fertilizer (though we are specifically targeting regenerative organic, where fertilizer is not used).

This is great news for those invested in ARM CPUs. I, for one, purchased a Lenovo X13s when it first came out for around 1,900 EUR. Unfortunately, my experience with it on Windows was subpar, and it was even worse on Linux. At the same time, I bought my wife a MacBook Air (not sure if it was an M1 or M2), and it was snappy and very pleasant to use. I bought the Lenovo based on the hype from benchmarks, and it seemed like a capable system initially. However, I couldn't tolerate all its limitations and ended up returning it, as it performed no better than a Chromebook I had bought earlier.

I'm hopeful that Snapdragon will offer an alternative ARM platform for laptops that can handle more than just browsing. As consumers, we need options, and the more, the merrier. I'm still undecided about the short-term success of Snapdragon. For now, I'm betting/waiting on the MacBook Air with an M4 as my daily driver, although I do prefer the Lenovo ThinkPad format.

Out of curiosity , have you ever encountered any malware that exploits said CVEs? If a month delay would be so dangerous, Android users, even of new devices would be getting pwned left and right, let alone Android users of device no longer getting patches.

Source: Android user of old phone who hasn't been hacked yet so I'm not sure where exactly the dangers are, as the attack surface is mostly the web browser and the apps, both of which are scanned and covered by up-to-date patches from Google Play Store/Services even on my ageing phone. So as long as you don't browse extremely dodgy websites, and don't download shady apps you should be good as nothing else can't get to the Kernel CVEs on your unpatched phone.

Yeah, I'm sure some crafty malware dev can whip out a targeted virus that can exploit the chain of open CVEs on my particular phone through a MMS message or something, but I'm not sure targeting the 100 or so users left still using this old OnePlus model that's worth less than 20 Euros used (pointing to a user without much income), is a good use of their skills and time, when they could be frying much bigger fish with that know-how like going after Microsoft's Azure or something.

Nor am I being targeted by state actors who have these means. And if you are being targeted by state actors, they have access Zero-Days that even Apple or Google haven't patched yet so you're not safe anyway no matter what phone you have.
