hdivider··on Zoroastrians make a comeback in northern Iraq
I would bet Socrates is the strangest in that bunch, since he claims to possess no knowledge (episteme) at all. At one point, he says he is therefore the wisest of all, even though he sees wisdom (sophos) as something that humans can only strive towards and never truly attain.
hdivider··on Ask HN: What mental models do you use everyday?
Here's three:

1) "All things are ready, if our minds be so." - Shakespeare

2. Holon para ta moria (ὁλον παρα τα μορια). From Aristotle's Metaphysics. The whole is something beyond the parts. Commonly mistranslated as "the whole is greater than the sum of the parts" -- which misses the point completely. Mathematical understanding and metaphor is only one type of thinking, one way to understand a complete system. Valuable, for sure, but incomplete. The whole system -- e.g. a human, a team, an entrepreneurial opportunity with all its moving parts -- in its full expression and action, is beyond mathematics. Only your whole human mind can hope to comprehend it.

3) Companies tend to die -- but people tend to survive. People matter infinitely more. The most valuable thing of all is human relationships.

hdivider··on Chiastic Structure
Re: your last paragraph: that sounds awesome! Anything you can share on those texts? Sounds like a great idea.
hdivider··on How do computers generate random numbers?
PCIe and USB cards like this are available, generating TRNs using quantum optics:

hdivider··on Virtual contact worse than no contact for over-60s in lockdown, says study
Agreed, it's just not the same. I bet the effect is present for the younger folks, or even exaggerated because so much of a younger person's life depends on serendipitous interactions. We don't get those with scheduled digital calls.

Hope you're better soon. Glad you can still meet with friends.

hdivider··on Americans' life ratings reach record high
"These results are striking in contrast to the increasingly cynical outlooks we see on sites like Reddit and even HN. It seems like every comment section is full of negative comments about how terrible everything is or how terrible it's going to be soon. Results like this are a good reminder to log off and go interact with the real world for a more grounded perpsective."

Agreed, 100%. It's amazing how HN, Reddit and other places select so strongly for the pessimism of the intellect, but quickly shoot down the optimism of the will. Without the latter (informed by the former, sure), civilization would never have advanced this far.

Sure, we need realism. And knowledge of what will go wrong. But find the positive -- otherwise, it's more like a withdrawal of people's energy.

Thankfully, like you mentioned, the real world, away from these artificial rectangles, is often way more empowering. :)

hdivider··on Unveiling our new Quantum AI campus
>You realize quantum computing is ultimately just a few linear algebra operations right?

Quantum systems have wavefunctions though, which collapse to a state. And before collapse, these can interfere. The math of this involves way more than normal linear algebra. Especially when you consider the things we've simplified away -- e.g. how exactly the wave function collapses. (We just say it's 'abrupt' and kinda leave it there. But it's possible this has implications for quantum computing, once we think in quantum theory terms rather than CS.)

hdivider··on Complexity Explained
Complexity theory provides metaphors for nonlinear change, for one thing.

And most things in business are neither truly linear nor simple exponential. Yet most people in business revert to these two mathematical concepts.

For example, it might convince a CEO to keep working on a project because this 'emergence' thing may be happening -- where a non-complexity-empowered CEO might kill the project because there is no linear return, and no apparent potential for exponential return.

hdivider··on Whitehouse.gov Chooses WordPress, Again
What are the best alternatives these days to WordPress for non-technical people? I know of Squarespace and Webflow. Any others?
hdivider··on Why the Electoral College Will Be Banished
Sadly, you might be right. E.g. in another post he discusses the "mass hysteria" of covid...."psychogenic" illness, and this:

"The severity of the virus from country to country is a reflection of media coverage, not the other way around."

hdivider··on Andrew Ng: The suspension of H1B is bad for the US and bad for innovation
Like any other nation, the United States is in a competition for top talent. People who have other viable choices -- who are in many cases also those who stand a high chance to create a ton of value in the US -- will now put the US lower down in the priority list.

As Victor Hwang put it [1]:

"While other countries fight a global war for top talent, America just packs up the tent.

Facts: - Immigrants start new businesses at twice the rate of native-born Americans. - Immigrants founded 44 of the 100 largest companies in America."

hdivider··on John Conway has died
It appears he died by COVID-19:

https://dailyvoice.com/new-jersey/mercer/obituaries/covid-19...

I went through some of his work in detail while in college. While a mathematician, he clearly had the complexity-compression ability of a top-tier theoretical physicist. A great loss indeed.

hdivider··on Ask HN: Helping companies re-tool to make ventilators. What do I need to know?
Great points, thank you. Yes, I saw those two designs. I wonder if there is an effective effort to aggregate all open source designs.

Often engineers need to look at multiple designs to figure out how to most effectively re-tool. Especially because lots of parts may become scarce soon.

Agree on those vents and partnering with existing device manufacturers. My guess is we will see more applications of the Defense Production Act in the coming weeks and months, and so we might have a list of large companies scrambling to fulfill federal orders. Hence I think the FDA will attempt some innovation to implement approvals at crisis speed. (Hard to know for sure, of course. I have dealt personally with only the NIH in a limited capacity years ago, not the FDA.)

hdivider··on Ask HN: Helping companies re-tool to make ventilators. What do I need to know?
Thank you -- yes, this ventilator work is the modern equivalent of a side project, as far as it's possible in the covid age. Advice and communications work takes less of my time on the ventilator front since it's the companies doing the actual manufacturing.
hdivider··on An international comparison of the second derivative of Covid-19 deaths [pdf]
Full title (not possible to put as title because of HN limits):

An international comparison of the second derivative of COVID deaths after implementation of social distancing measures

hdivider··on Ask HN: How are you coping with all the (mostly bad) news around you?
Words of wisdom. Thank you. The human level doesn't get so much consideration here on HN -- and yet it matters more than any other thing.

Protect yourself, your family, and simply do good for others as much as you can.

hdivider··on P3: Pandemic Prevention Platform (2017)
Good point. Changed it. Got the DARPA press release title confused with the popular mechanics article. :) Thanks.

Great, thanks!
hdivider··on Ask HN: How did you fix your narcissism?
Can you name any of those psychotherapy podcasts? Would love to know.
hdivider··on I ditched Google for DuckDuckGo
Yes, I agree. They shouldn't force people to dismiss some popup.
hdivider··on I ditched Google for DuckDuckGo
Why not use ddg.gg? Even shorter.
hdivider··on WARP is here
I love it. You always have to make privacy and security tradeoffs -- and to me WARP is a promising initiative.

Question: is there an OSX version? Or am I just blind? :)

hdivider··on Many more trees could be planted without encroaching on crop land or urban areas
Given the right approach, this is also probably the only way to tackle climate change that is self-sustaining. Because trees reproduce. And they constantly search for ways to adapt to their environment in order to survive and reproduce.

Human technology can't do that yet.

hdivider··on The End of More – The Death of Moore’s Law
I hear 3D circuits being touted as the next frontier:

https://en.wikipedia.org/wiki/Three-dimensional_integrated_c...

Heat dissipation becomes a major challenge there though.

What other emerging technologies could help us restart Moore's Law?

Or is this truly the end of the line?

hdivider··on The Scientific Intelligencer (1993)
A CIA library entry written by a Brit. I find it continually fascinating how close the US-UK intelligence and defence establishments are.

Can anyone speculate at the reasons for this? Is it the extreme cultural closeness, the Special Relationship fostered through WW2, or simply realpolitik -- i.e. US-UK having broadly speaking the same national interests?

Or something else?

Or do we just get on so well because we like each other's accents? :)

hdivider··on DIA Study: Warp Drive, Dark Energy, and Manipulation of Extra Dimensions (2010)
Was it a fizzle? Didn't they get an "inconclusive" result, rather than a negative one?

(No criticism intended -- I really want to know.) :)

hdivider··on I’m Peter Roberts, immigration attorney who does work for YC and startups. AMA
If a non-US citizen works with a US LLC remotely, with changing responsibilities (basically as an informal partner in the firm), is there any immigration path to bring this person into the US?

[Side note: thank you for doing these repeated AMA's, Peter. You address a vital, often deeply emotional problem for countless people. Hats off to you for taking the time to de-mystify so much of this.]

hdivider··on Can we know what animals are thinking?
Takes courage to make such statements on HN. Kudos to you for that.

Humans are biased to view themselves as the most evolved, sophisticated and important species. A glance at the history of science shows this.

Slowly, we become aware of our bias and notice how damn lucky we are to survive to this day.

Ages ago, nature almost killed us off:

https://en.wikipedia.org/wiki/Toba_catastrophe_theory#Geneti...

And in modern times, we almost wiped out our civilization many times:

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

We are lucky to be here. Gotta make the most of it. IMO a good place to start: to value the other surviving animals on this planet. You could travel 10,000 light years but you will find them only on Earth.
