lldbg··on Political Detox Week – No politics on HN for one week (2016)
I might be in the minority here but I enjoy the political threads. I think the reason they often devolve into "discussions" of sub-par quality is that much of politics can't be explained by reason, and so is it with most of our values. We might attempt to do so, and philosophers and logicians have, but in the end that feels hollow. So then we might devolve to social pressure (i.e. resenting those who do not agree with us). When that fails, there are insults and after that violence.

It does not look like there will be any underpinning of all values and morals that a majority of us will accept or understand. So that leaves us the question: how should we disagree? I think the current way is fine, perhaps we could all strive to be less enflamed by views contrary to our own held beliefs, but do not think that the situation couldn't be way, way worse.

lldbg··on Analyzing the performance of Tensorflow training on M1 Mac Mini and Nvidia V100
George hotz got his "for play" tensor library[a] to run on the Apple Neural Engine (ANE). The results were somewhat dissapointing, however, and currently it only does relu.

lldbg··on Simulating Fluid Dynamics with Cellular Automata (1986) [pdf]
Well known in academia, but what type of industrial applications is it used in? To my knowledge most mainstream software suites run plain old RANS finite volume schemes.

In C++, name mangling is used to solve this issue
lldbg··on Early clinical trial shows anti-depressant prevents hospitalization from Covid
To be clear, I am using the example of the current vaccines to prove the point that N=200 allows statistical inferences to be drawn.
lldbg··on Early clinical trial shows anti-depressant prevents hospitalization from Covid
Yes, you have. The efficacy estimate was based on roughly ~200 confirmed cases, which your link confirms for the Pfizer vaccine.
lldbg··on Early clinical trial shows anti-depressant prevents hospitalization from Covid
The efficacy of the vaccines currently being administered to millions were based on decisions made with data from ~200 confirmed cases.
lldbg··on Identical twins are not so identical, study suggests
Your first link is a blogpost about someone's doctoral dissertation, and your second link is even more of a stretch (the title of the paper ends with a question mark). That is fringe research, and not the established position. You get what you search for.

As for cultural loading in intelligence tests, maybe you could expand on that? How do you measure how much culture was involved in the methodology, and how it affected the results of the tests?

lldbg··on Identical twins are not so identical, study suggests
Go look up eg the sources on the wiki article, and you can see for yourself how they controlled for nurture.
lldbg··on Identical twins are not so identical, study suggests
By having lots and lots of good data.

80%+ is what the current corpus of scientific knowledge says. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4270739/ Here's a somewhat good primer on the topic, but the wikipedia page on heritability of intelligence (and it's sources) is also somewhat good.

25% of the variance in sexuality is genetic or heritable. Compared to approx. 80% for intelligence. A small genetic component, but it seems as if experiences are the major deciding factor for sexuality.

He didn't, though.

Among the first few pages in many of my books are recommendations for other similar books from the same publisher, and not infrequently the author himself cites related works.

There was this blogpost a while back which I can't seem to find, suggesting that the division is between:

* people who view democracy as a set of values, and if you do not share those values then you are against democracy.

* people who view democracy as the democratic principles (voting, representation, freedom of assembly, and so on)...

In my world (I belong to the second group) democracy is freedom of speech, the exchange of ideas, and coming face to face with values and opinions that you do not agree with (in fact you may find them abhorrent), and thinking that that's the whole point.

I found it an enlightening take on the situation, and thought that I'd share it here.

lldbg··on Reddit bans subreddit group “r/DonaldTrump”
"We can guarantee freedom of speech, but not freedom after speech." Idi Amin.

This year I have barely spoken more than 30 minutes to someone in real life, per day. If my interactions over the internet were to be as they say curated, I would effectively be silenced.

I was a frequent reader of r/dt a few years back, as the top poster was. There was nothing in particular there, no trend, that was any more terrible than what I could find in my bookshelf. Deal with it.

lldbg··on Avoiding instruction cache misses (2019)
In my experience Eigen is not very good either for small matrices, whilst Fastor performs much better.

Interesting

lldbg··on Avoiding instruction cache misses (2019)
Could you expand on the 24x24 unrolling with AVX? How big of a benefit did you obtain, compared to say using a library such as Armadillo, Fastor, Eigen, etc?

lldbg··on Our Response to the Violence in Washington
I think that generally people are in favour of so called "fact" checking, if the results of that fact checking align with their beliefs. As a silly analogy, how about a road that gave you a thumbs up when you had the right of way? The platform is an authority, and we like authority to echo our own beliefs.
lldbg··on Huawei Tops Intel as Top Linux Kernel Contributor for 5.10
I haven't seen any good studies debunking it, but neither have I seen any studies which prove it. That IQ is heritable and has a large genetic component however is "settled science" [a], and the current trend in behavioural genetics seems to be that a large swathe of cognitive and social behaviours are very heritable indeed.

lldbg··on Electric cars make up 54% of cars sold in Norway in 2020
This is a bit facetious but, my point is that driving to the airport in a tesla isn't solving climate change. The guy in India who lives in a house with dirt for floor is solving climate change, no matter if he likes it or not.

No, the solution is leaving the oil in the ground, anything less than that and what you're making is excuses and not progress. We can't keep moving the goalposts.

There is nothing good for the climate about 13 norwegians (to reference another comment on this article) buying luxurious cars that happen to be electric.

I doubt renewable micro-grids are going to power EVs in the third world anytime soon, but that would be nice I guess.

lldbg··on 27th International Obfuscated C Code Contest winners published
The highlights include a game of tic-tac-toe solely in several calls to printf(fmt, arg), where fmt and arg are carefully chosen.

This made me reflect on whether good language design should limit expressiveness of code?

lldbg··on How I learned to love and fear the Riemann Hypothesis
"Complex Analysis: An Introduction to the Theory of Analytic Functions of One Complex Variable" By Lars Ahlfors was very enjoyable to me. However, I read it after I already knew Complex Analysis.
lldbg··on Electric cars make up 54% of cars sold in Norway in 2020
Yes, I am aware (why wouldn't I be?).

To me it is obvious that the solution to the global climate change crisis isn't rich countries buying new luxorious cars, that happen to be electric. That's a very western-centric view.

lldbg··on Electric cars make up 54% of cars sold in Norway in 2020
Sell oil, buy electric cars. Is this the definition of hypocrisy? At least it is better than the alternative, sell oil and buy fossile fuel cars.

Edit: I would like to rephrase the last sentence as "At least it is better than _an_ alternative, which is to sell oil and buy fossile fuel cars." which is a fairer categorisation of the problem space and less consumerist.

lldbg··on School or Prison
Well, certainly this case in particular is one of morals in so far as I understand the concept of morality. To me, sexual relations with children is immoral, it is not proper behaviour in which an adult should partake.

Foucault seemed to think it was, if not proper behaviour, then at least not-unproper. That is a moral judgement.

To suggest that Foucault was above the entire concept of morals as I understand you to do, well I can't agree on that and I don't think he would either. Of course he was trying to be a moral authority, remember that this whole thing was about him (and others) attempting to legalize sexual relations with children. If he did not think himself an authority, on what merit would he petition? And barring that, it is clear that he was and maybe is an authority, because here we are half a century later or so still discussing his position.

His experiences does not excuse him in my eyes. Neither does it impact to the slightest degree the truth-value of his position on this issue, nor of his philosophy overall.

lldbg··on School or Prison
I don't think so. A philosophy should be self-consistent, so if I can use Foucaults own words to critique his position on pedophilia, all the better.
