cycomanic··on Sustainable energy without the hot air (2008)
There was some statistics on capital in the 21st century by Picketty (maybe from Kindle readers?) that most owners of the books only read the first 10 pages or so. Am on mobile but should be easy to find.

Not necessarily saying this generalises to all non fiction books though

cycomanic··on Italian parliament votes for return to nuclear energy
That myth keeps persisting. In reality per $ of the project wind farms face significantly higher regulatory costs in many countries. Nuclear power operators also managed to get regulations on the turbines dropped compared to coal plants (in Germany IIRC).

In reality we see it time and time again, the larger a project (and that applies to pretty much all infrastructure) the easier it is for the operator to get regulations loosened, because of the large amount of money involved, they tend to have much more leverage over politicians.

cycomanic··on Asking authors about their own papers
It's often denoted plagiarism or self plagiarism as a short cut. While it's probably better denoted duplicate publication (or similar) it still constitutes a similar academic misconduct, because you're pretending something is novel without it being novel

As a side note quite often it can actually be literal plagiarism as well, many journals require you to assign copyright, so using that work without attribution is plagiarism.

cycomanic··on English: A vs. An
Back in the days when I had to take some latin for my studies, our lecturer always used to say "don't ask my why, latin might be more logical than most languages, but it's a language not math. Languages are not logical". It actually became a bit of a running gag because we still had some students who needed to ask why for every rule.

Net immigration was never more than a million (let alone "millions" which was the lie I responded to). It reached a peak of 900 000 in 2023.

There are no millions of people every year, stop spreading lies. Net immigration to the UK in 2025 where 170000 people. Decidedly not millions!
cycomanic··on U.S. State Department pauses immigrant visa applications
"huge uncontrolled levels of immigration". Let's put some actual numbers to this. Net immigration in 2025 was about 170k people, over the next 10 years projections are for about 2.2 million net immigration. So that's about 3-4%. However, UK population is shrinking without immigration so net population growth with immigration is about 1.7 million.

Not sure if that matches a definition of huge, but it's important to note that with a shrinking population without immigration the UK would be in serious economic trouble (like every country). This is even more exaberated due to the aging population that the shrinking population implies.

Immigrants like always are the convenient scapegoat that is being used to distract from the increasing gap between the rich and everyone else.

cycomanic··on Controversial creators are benefiting from monetization programs run by Meta
That is simply not true. One example is a hilarious skit by an Australian comedian (John Safran) going to salt lake city and knocking on doors asking if he could talk to people about atheism. The amount of violent threads he received is quite revealing.

In my personal experience having lived in the US and several other countries, I found officially people can say much more things (i.e. due to the strong freedom of expression laws), but in personal settings you are much more likely to be shut down, fired, threatened with violence, ostracized... for stating unpopular (in that social environment) opinions, in the US compared to the other countries.

cycomanic··on Danish high schoolers will have to verbally defend written assignments
There was an interesting talk I heard a while ago about the scalability of oral exams vs written. They did quite a bit of study of typical exam preparation and marking times and the cross over point where oral exams were actually taking longer than written exams was surprisingly high, around 180 students or so. To be fair though I think they considered 15 min oral exams, but the gist is that in the scalability argument people tend to forget to account for marking and exam design time appropriately.
cycomanic··on US strikes $1.2B deal to pay German firm to halt offshore wind projects
> Even in Texas/California photovoltaic output in the winter is measly, anywhere more to the north and it's effectively inexistent. Solar+storage requires massive overprovisioning, to the level that it's cheaper to burn literal money.

cycomanic··on US strikes $1.2B deal to pay German firm to halt offshore wind projects
One additional tidbit of info. While the northern coast in Germany has certainly more wind, a reason why wind falls off so strongly towards the south, are the policies of the CSU party in Bavaria, which though not quite as bad as trump has been running Anti-Wind policies and making wind installations extremely difficult to build.
cycomanic··on Show HN: XY – A Fast, composable, GPU-accelerated interactive plotting library
I can give you a prime example where you want to render all the data and quickly, oscilloscopes. It's quite common that you fetch traces with millions of samples, but then want to zoom into specific regions. There are lots of similar applications in experimental signal processing, where you want to have large data sets, but sampling easily will hide details that you want to see (unless you already know what exactly your data looks like).
cycomanic··on US citizen charged after GrapheneOS phone wipes during airport search
> The parent described a story from a different reality - one where people are people, where communities have basic expectations of conduct, and authority is respected on all sides. The cop was angered and snapped (bad), but was stopped by their partner (good, and it's one of the reasons cops have partners!). The parent was a kid who behaved like an asshole in a moment, by their own admission. Plenty of teenagers act like that, it's an age-old more. The judge did not act as a proxy for the angry cop to retaliate, but instead reacted correctly by both praising the civic attitude (to the chagrin and I imagine further embarrassment of that cop), and addressing the behavior that is not welcome in a civilized community.

So why did he not give the cop community service then?

cycomanic··on What happened to TheNumbers.com
But the AI companies are not publishing the models? Moreover they are charging for access to the models.
cycomanic··on What did SFFA vs. Harvard reveal about admissions?
You conveniently left out the fact that all the "easy" tracks (athletics, legacy, donor) are heavily skewed toward white applicants. It's interesting how everyone is riling about affirmative action, while at the same time nobody bats an eyelid about those nepotism tracks. And those definitely seem to be institutionally biased against black and Hispanics (in particular the Athletic track it seems, considering the proportion of black athletes in professional sport).
cycomanic··on Professor denounces mass AI fraud on an exam at Brown
> When he reported the case to high-ranking officials at Brown, he got a cold reaction. The response from the president, he said, was absolute silence. The dean did not comment either until Serrano took the case before the Academic Code Committee. At that point, he received a note acknowledging that what had happened in his classroom was “a wake-up call.” Serrano, a Madrid-born economist who has been at Brown for 34 years, believes this is not enough. “That cannot be the university’s position before an incident of this magnitude. Academic integrity is a value worth defending. The faculty cannot be left on its own

Is anyone surprised that the academics are essentially being left on their own about is? University management has become increasingly disconnected from the academics doing the work on the ground at least during the last 20 years that I've been in academia. Covid was really an eye-opener in this respect, at our university academics were told with very short notice to make all lectures remote. There was essentially zero support from central management, there was not even budget to buy headsets or cameras and academics were expected to use their research funds.

At the end of the pandemic academics were thanked with two years of 0 and 1% salary increase, due to a tough economic situation. During the same time the president received a 8% raise. The tough economic situation was entirely due to mismanagement, i.e. the university had invested pension funds into fixed interest investments which did not keep up with pension growth (during a time when stock markets were going from strength to strength).

cycomanic··on Micron locks in historically high memory prices for five years
> Because software you build it once and can resell it as much as you want, a stick of RAM is only sold once.

Yes exactly, and theoretically if there was a functioning market that should have driven prices way down, because the marginal cost to enter the market is so low. However, the non-functioning anti-trust laws as well as the expansion of ip laws as allowed a few enormous corporations to essentially control the market and keep prices up.

> Arguably software is much more difficult to build because it is never complete.

There are hardly any hardware companies where the hardware is ever complete. Disregarding the fact that many hardware products contain some form of software that needs to be updated. In pretty much any field hardware companies need to continue developing new revisions/improvements on the hardware to stay ahead of their competitors, however those revisions/improvements are significantly more complex to put into reality.

cycomanic··on Micron locks in historically high memory prices for five years
It's funny how everyone (especially here on HN) accepted (and expected) extremely high profit margins from software businesses, but now that hardware companies are increasing their margins to match it is suddenly outrageous. The same was reflected in engineering salaries, with software engineering salaries being often a multiple of hardware engineering ones. All this despite the fact that software businesses is arguably much easier, less risky and less capital intensive.

For decades now we have seen the expectations that software businesses (and in particular FANGs) have pushed any hardware margnins to be more and more like commodities, while they were extracting all the value.

cycomanic··on Anthropic says Alibaba illicitly extracted Claude AI model capabilities
If I understand your argument it's ethically ok to destill huge swathes of copyrighted work into a model without compensation, but then it is ethically wrong to use that model without compensation (well actually reduced pricing)?

I don't get the moral framework that you're applying. Could you elaborate?

cycomanic··on Canada plans 'nuclear renaissance' with up to 10 reactors built by 2040
That's not how electricity markets operate. Say you have 100GW demand (number are not in any way related to reality) and your Nuclear plant has a capacity of 50 GW. However it's a sunny day and solar is producing 80 GW. That solar will be producing at a much lower price, so no one is interested in buying that extra expensive 30 GW from the Nuclear plant (I'm glancing a bit over how pricing works exactly, but it comes to the same thing).

So either you restrict the amount of solar that can be produced or you subsidize the Nuclear prices. Both solutions are increasing prices for idiological reasons. If we do that might as well invest in solutions that are on exponential trajectories, like solar and battery.

The whole baseload argument when talking about renewables is a strawman. Both intermittent (like solar and wind) and constant output (like Nuclear) are baseload technologies, despite working very differently. Both require over provisioning, on demand sources or storage. It does not make any sense to bet on a solution that despite significant subsidise over almost 70 years has failed to produce any exponential count reduction, if the other solution is on an exponential curve right now.

cycomanic··on How to feed a dictator
It seems your misinterpreting the quote, it does never says that

> “These everyday things that are beloved to us, like food, can take on an entirely different dimension within the context of a dictatorship.”

Is the definition of the banality of evil concept. I would argue though that within the concept you will interpret banal things differently. For a more blatant example, the banal act of putting an approval stamp onto a piece of paper will be interpreted quite differently in the context of a administrator in Reichsbahn in Nazi germanycompared to an administrator at the Bundesbahn now.

cycomanic··on Gribouille 0.3.0: A Grammar of Graphics for Typst
If you restrict typat to the basic functionally of markdown it is just as readable as plain text (not surprising considering that typat syntax was inspirered by markdown). However, once we include more unusual things I would argue that markdown becomes more illegible than typst (as for markdown you start adding html essentially).
cycomanic··on Gribouille 0.3.0: A Grammar of Graphics for Typst
I'm not sure what you mean. Markdown compared to typst or latex is extremely limited and using it for books or academic papers is very niche. I certainly would (and have for all my previous publications) prefer typst or latex over markdown. I also don't understand your point about not permitting typesetting during writing. Latex and text are the prime examples of separating writing from typesetting.
cycomanic··on US battery manufacturing output continues to break records
But by that argument the EU holds all the cards because nobody can do what ASML can do. So everyone is dependent on the EU.
cycomanic··on A 'cold blob' in the Atlantic could be a sign of AMOC shutdown
That ignores the fact that there is a incredibly well founded coalition of organisations with idiological (climate change by its nature requires collective action, but collective action is bad...) and economic (big oil, big tobacco...) motivations that has been running a massive desinformation campaign for decades. We know desinformation is much easier than factual information, climate change is almost a poster boy for this. It would have not mattered an iorta if "environmentalists" would have used different messages, in fact they primarily used exactly the messages you proposed, the fact that you remember it as being ”you all have to suffer to save the planet" just shows how powerful the desinformation campaign was. Because that was their prime message, not the one of climate activists.
cycomanic··on Claude Fable 5
Ah apologies, that's what I get for skim reading and kneejerk replying. I completely agree with you, undergrads are highly unlikely to know more about a subject than their professor (obviously there can always be exceptions).
cycomanic··on Why SpaceX 2040 Revenue FCST $4.3T in highly unlikely
Like what? Seriously, nobody thought shouting rockets into space was impossible. Landing a rocket again nobody had thought it impossible. Sure they brought down prices, again nobody thought it impossible. The question is actually is it desirable. Rocket launches are pretty much the worst one can do in terms of greenhouse gas emissions, but somehow all technerds are falling all over themselves how great it is.
cycomanic··on Claude Fable 5
It certainly is true in physics and engineering that a PhD student at least half way through their PhD should know more than there supervisor about their topic (and usually much earlier). Even a Masters thesis project student should understand the intricacies of their project better than their supervisor. I'm speaking as someone who has supervised a significant number of both PhD and Masters students.
cycomanic··on Surprise, pay $1000
Can someone explain this statements:

> While amusingly as of June 8 Blacksmith’s terms implied that their right to bill you is contingent on you providing payment information, a SaaS app certainly could have terms that obligate users to pay for unexpected overage when on a free trial.

> And let’s be clear: our agents run a lot of CI jobs, so we did expect to hit the limits of the free plan. We used the service and got value for it. So it’s not inherently dishonest, just surprising. My read is that they can do this.

So I read this that the terms say "blacksmith will only bill you if you provide payment information" but then they say that blacksmith can bill you if you don't provide payment information. That seems to contradict the terms, which I would assume underlie the "contract" that you agree to when agreeing to the terms.
