hnaccount_rng··on Can “second life” EV batteries work as grid-scale energy storage?
In addition to my sibling comment: The cost of the panels is a rather small fraction of the total cost of a typical installation. Most of that cost ist labor, some regulatory requirements and the inverter. Whether you pay a factor of 2 for the panels or not typically doesn't matter. In other words: Reusing used panels will only ever be able to safe you a minuscule amount.
hnaccount_rng··on Beliefs that are true for regular software but false when applied to AI
But that's not the same thing right? That means having two teams competing for developing the next product. That's not two organisations handling the same responsibilities. You may still end up in problems with infighting. But if there is a clear end date for that competition and then no lasting effects for the "losers" this kind of "competition" will have very different effects than setting up two organisations that fight over some responsibility
hnaccount_rng··on High-power microwave defeats drone swarm
I don't think a fraction of a second interruption would be overly problematic. These drones are somewhat heavy and thus bring relevant amounts of momentum. But the start up process is probably far too long
hnaccount_rng··on Demand for human radiologists is at an all-time high
I think the one thing we will find out with the AI/Chatbot/LLM boom is: Most economic activity is already reasonably close to a local optimum. Either you find a way to change the whole process (and thereby eliminate steps completely) or you won't gain much.

That's true for AI-slop-in-the-media (most of the internet was already lowest effort garbage, which just got that tiny bit cheaper) and probably also in medicine (a slight increase in false negatives will be much, much more expensive than speeding up doctors by 50% for image interpretation). Once you get to the point where some other doctor is willing (and able) to take on the responsibility of that radiologist, then you can eliminate that kind of doctor (but still not her work. Just the additional human-human communication)

hnaccount_rng··on Demand for human radiologists is at an all-time high
You also have Mercedes taking responsibility for their traffic-jam-on-highways autopilot. But yeah. It's those two examples so far (not sure what exactly the state of Tesla is. But.. yeah, not going to spend the time to find out either)
hnaccount_rng··on AirPods live translation blocked for EU users with EU Apple accounts
Oh, if I were travelling a lot to other countries speaking to non-english speakers and an alternative offers live translation and AirPods don't. Then this is pretty much the _first_ real argument of not buying AirPods. And once you do start switching out of the ecosystem remaining in it is much less attractive
hnaccount_rng··on The MacBook has a sensor that knows the exact angle of the screen hinge
It should also be relevant for triggering the "closed let's lock the device" event, right?
hnaccount_rng··on AI’s coding evolution hinges on collaboration and trust
I’m not sure if your statements are actually correct. What you are implying is that there are fewer tailors today than in the past. And I’m not sure if that holds. I’m not even sure that their relative position on the income ladder has deteriorated.

In the time before automated T-shirt production, almost nobody bought clothes. They were just far too expensive. There were of course people that did. And those paid extremely well. But those kinds of tailors still exist!

At the same time, I do think that the comparison is less than apt. And a better one would be comparing it to the fate of lectors and copywriters. A significant amount of those have been superseded by spellchecking tools or will be by AI “reformulations”.

Yet even here I’m not sure if those jobs have seen a significant decline in absolute numbers. Even while their relative frequency kind if obviously tends to 0

hnaccount_rng··on Unexpected productivity boost of Rust
Yes but the alternative is "not having those projects at all" not "having them in a 'better' language"
hnaccount_rng··on Do things that don't scale, and then don't scale
You can't though. The problem is, that humanity is a web. Not a set of communities (at least on the scale of 1000s of people). And since those webs overlap you will either need to solve the overlap problem at the boundaries (taking engineering effort) or you will end up with essentially one big shard again. On the other hand, you really don't need to change anything on the backend. Simply limit the number of "tier 1" friends to 50, have a "tier 2" category for your 1000 and put everything else in "acquaintances" and split engagement between those.

The problem with that though is: You will generate an enormous amount of social friction "why am I tier 2, but (without loss of generality) Karen is Tier 1?" and reduce monetizability. So truly nobody will feel happy about those restrictions. And since it doesn't solve any engineering problem you run into (see above) there is no one incentivised to build such a thing. (Ironically this may not be completely true, given that this is pretty much how Chinese social media apps work. So maybe states [or at least power structures] are incentivised to build such a system)

hnaccount_rng··on When DEF CON partners with the U.S. Army
Then you have ignored the majority of the event. Don’t get me wrong, I’m also there for the technical talks or at least tech-related talks. But most of the tracks aren’t that.

And I would say at least 50% of the assemblies and Co are political. The Sea Watch people, the ones who are regularly detained by Italian authorities have their home base there.

The CCC, as an organisation, always has been a political organisation first. I wouldn’t call them a particularly successful one. But they are the opposite of agnostic or worse apolitical

hnaccount_rng··on When DEF CON partners with the U.S. Army
You really may want to look up where and how CCC was founded. I’m always amazed at people being shocked that left to extreme left politics are the norm on an event from an organization that was founded in Kommune 1 in hippy Berlin
hnaccount_rng··on CO2 Battery
How do these numbers compare with traditional methods?
hnaccount_rng··on My experience with Claude Code after two weeks of adventures
Yeah that is kind of my experience as well. And - according to the friend who highly recommended it - I gave it a task that is "easily within its capabilities". Since I don't think I'm being gaslighted, I suspect it's me using it wrong. But I really can't figure out why. And I'm on my third attempt now..
hnaccount_rng··on Why recycling solar panels is harder than you might think
Wow. I did not expect a single panel to weigh 15+kg. TIL
hnaccount_rng··on OpenAI delays launch of open-weight model
We absolutely regulate which words you can use in certain areas. Take instructions on medicine for one example
hnaccount_rng··on Solar power has begun to transform the world’s energy system
Of course it seems like wishful thinking! Because that’s the historic norm. Energy was (in some way) always the limiting factor. And every time energy access got meaningfully cheaper society massively reorganised around it.

And yes “energy” in general won’t be free. We still need to build the generation and distribution systems. But we reached a point where just dumping solar on all _new_ roofs rounds to essentially free (the costs are the labor and the access to qualified personnel). The exact same is currently happening to batteries. Any transformer project will be able to just integrate 4-12 hours of batteries without getting meaningfully more expensive. The same for every domestic or industry service upgrade

We are not there yet. But give it another 5 years and we will. And then we are only talking about financing what little distribution system we will need (basically you only need average-sized cables not peak-sized ones) and a capacity market for backup power systems (also only for average residual demand). And those we simply cannot (efficiently) finance by a per-kWh-used charge

hnaccount_rng··on Breaking Git with a carriage return and cloning RCE
_I_ would agree with you. But I’m also not a person writing a version control system for a kernel that still runs wrong-endianess hardware (I forgot which one we are using and can’t be bothered to look it up). And I think a major part of this is, that I assume that something is so insane, that people just shouldn’t do it and the people steering the kernel or git don’t (get to) assume that

Then go back to the beginning of WW2 and look up the biggest trading partners for both Germany and France
hnaccount_rng··on Solar power has begun to transform the world’s energy system
It may never be “worth” it in economic sense, but it offers a way to separate the time of “energy is used” and “energy is available”. Assuming sufficient captureable volume you could capture the emissions of a fossil power plant during the ~two weeks per year where weather is sufficiently bad. And then take the other 50 weeks to capture that carbon again. It can be completely inefficient (like sub 5% round trip efficiency) if a) we pay for it via a capacity market and b) have sufficient excess (clean) energy to run it
hnaccount_rng··on Solar power has begun to transform the world’s energy system
That’s only a problem if you care about the stranded investment side. The energy industry isn’t that personel intensive (plus you could just continue to employ the people). But they absolutely will deprecate the power plants and stop buying the coal. The former will bankrupt some of the projects which planned with much longer repayment periods. The latter will immediately safe money
hnaccount_rng··on Solar power has begun to transform the world’s energy system
They are also old technology and only about half as efficient as current ones. So even if you restore them to full nameplate capacity for free they are still wasted to put anywhere as long as the installation price is dominated by labor costs. The _only_ scenario in which this might be worth it is if there are no new solar cells available
hnaccount_rng··on Solar power has begun to transform the world’s energy system
That was the idea behind Germany’s energy dependence on Russia. Let’s call that experiment not successful, shall we?
hnaccount_rng··on Solar power has begun to transform the world’s energy system
But that isn’t the case _today_. Unless you have existing facilities (which we do have and which gives fossils momentum) it’s strictly cheaper to build new renewables! The problem for renewables is that the p99.9 price is much higher than the p95 price. But finance will be solving that part.
hnaccount_rng··on Breaking Git with a carriage return and cloning RCE
Which kind of makes it an unsuitable solution for the given problem right? Git is not free to (or at least doesn't consider itself free to) work only on a subset of possible paths.
hnaccount_rng··on Apple just released a weirdly interesting coding language model
That depends on whether these current learning models can really generalise or whether they can only interpolate within their training set
hnaccount_rng··on Apple just released a weirdly interesting coding language model
Do you have an example?
hnaccount_rng··on Apple just released a weirdly interesting coding language model
The number of people that would but a NAS over just spending the 5$/month for storage is well below a percent and if you combine that with the requirement of not having a PC/Mac you may well end up in the hundreds…

There aren’t that many people that are willing to own a device from a company but not trusting that company with their data

hnaccount_rng··on Apple just released a weirdly interesting coding language model
But if the limiting factor is the data on which the models are trained and not the actual “computation” than this would be exactly expected right?
hnaccount_rng··on Stop Killing Games
But in order for an unskilled (no value judgement intended) person to fix that, this means having the technician run out to their house and find out whether that's the case. That's an hour of work, at least. What does a new oven retail for? Add to that the expectation value of "need to come back because it's not the first thing I tried" and that replacement oven with fresh warranty starts looking even cheaper
