Huh?

Robots with vision + sounds sensors and connected to the internet in professional homes across your country are definitely a security issue.

If you don't own the customer relationship, you don't own the profit. See App store, FB.

NVidia is delivering commodity hardware to the hyperscalers, and would eventually get commodity margins (when hyperscalers make their models work on their own hardware).

Amazing article on relevant economics of squeezing vendors - actually about antitrust ad-models but:

  The answer is that [advertising based] companies are an ideal test case for an increasingly common business meta-model, where companies try to create a consumer surplus at one end in order to maximize their negotiating leverage for capturing the producer surplus everywhere else in their supply chain.

> you can’t control every Taco Bell

Restaurants and fast-food outlets generally can't/don't avoid their staff making sketchy health decisions.

Don't eat at them if you're worried.

Read anything about back-kitchens and staff's interesting attitudes towards health risks.

I highly recommend Kitchen Confidential - amazing novel writing.

Although my intro to the genre was 1933's Down and Out in Paris and London (an upper-middle class хорошо horrorshow). An all-time favorite book.

The survivorship bias is strong in you.

You're ignoring unsuccessful mutations... But those are the chaos monkeys that really matter!! "on the order of 10¹⁷–10¹⁹ individual nucleotide mutations per month". In part because infectious virions are far fewer than total viral RNA copies.

Which ends up with 2-3 mutations per month in the successful lineage. That's the "rare" number you're thinking of, but mutations are extremely common (as anyone with cancer finds out).

Your "energy" point is just plain wrong. You might carry 100ug of virus when infected - a tiny proportion of your weight. Total mass of virions in humanity at peak might have been 10kg.

See "The total number and mass of SARS-CoV-2 virions" https://pmc.ncbi.nlm.nih.gov/articles/PMC7685332/

Hacking and cheating are different things.

Hacking is looking at the rules and finding smart ways of following them. A lawyer or accountant finding legal loopholes is hacking.

The clearest place to see hacking is within games where one follows the rules and does not cheat.

Avoid thinking that hacking is unethical behaviour. A common mistake of people that don't understand the culture.

Like many great words, the meaning does depend on who uses the word. But the people who created the usage didn't use it for cheating.

> energy

That is almost irrelevant.

Our immune systems, and environments are mostly security-by-obscurity.

Viruses randomly mutate to find vulnerabilities.

Their biggest issue is finding solutions using a genetic optimisation algorithm.

Their biggest strength is that it is a massively parallel search. Think of 10^x monkeys bashing at all points in their reproduction (maybe 10^18 for peak covid in human hosts).

robocat··on Why older tech is sometimes safer from hackers
> You really need to treat it as untrusted and build your security on top with encryption, authentication, authorization, etc

Infrastructure usually has a long lifetime.

Things become much more vulnerable as time rolls on e.g. we should be worried about AI hacking of smart meter firmware (hard to secure and expensive to upgrade).

Today's secure system is tomorrow's insecure system. E.g. https://news.ycombinator.com/item?id=49413320 :

  Finally, I poked at something that wasn’t connected over USB but WiFi instead, the Elgato Key Light Mini. This one turned out to be way more interesting than I expected: it’s the only one with meaningful firmware integrity protection.

  Unfortunately, while that’s an improvement over all of the other devices we’ve looked at, it protects the firmware at exactly one point in time: when an update is happening. It’s not a boot time check enforced by the bootloader or any other kind of secure boot scheme, and the updater happens to be running while everything else in the device is still operating, meaning there’s huge attack surface to try to disable that signature validation. I asked Claude to look for an exploit that might enable this, and it found a doozy

Telomeres are part of your anti-cancer mechanisms (they stop cell reproduction after say 60 DNA self-copies to help fight unbounded cancerous growth).

If chasing 'benefits', you'd want to be careful before fucking with that mechanism.

Yet every non-uni worker seems to develop those skills without going to university.

It would be interesting to measure. Critical thinking in particular doesn't seem to be taught.

I personally believe none of those skills were taught during my own engineering degree. For me it was a lot of simple regurgitation against closed ended test questions. In hindsight mostly a fucking waste of time: a piece of paper to get a job.

Ideal socialism is voluntary, just like ideal free markets.

I wonder whether your axiomatic belief is that we should all have freedom? Therefore you love the idea of free markets? I wonder if some of your "free market" comments would be better written in terms of freedom rather than economics.

Game theory and evolutionary stable strategies show the issues of cooperation versus defection.

Voluntary cooperation fails because power is required to enforce fairness/contracts and then the powerful can defect. That is independent of socialism or free markets.

Also authoritarianism and socialism are different things, even if history shows correlation. Socialism is a deeply tarred word, with radical differences in meaning (approximately equal to communism for many, or democracy for others).

If authoritarianism is a stable outcome, then it can be an outcome of free markets too.

Re your other thread: calling China a free market seems extremely odd, and basing any argument on that 'fact' is even odder. Edit: perhaps "Socialism is coercive cooperation" is similarly nonsensical.

Patents are not discussed as inventions any more.

Other aspects now matter: defensive patents, patent pools, patent trolls, patent portfolios, etc.

Triple damages made a farce of patents as dissemination of invention.

Status?

Children are no longer a symbol of status, and they also reduce money status. Modern culture seems to prioritise other status ladders than making a family.

Of the 20 year old women I know, few seem to want children versus the old "I want a baby" stereotype for young women. When one has a baby and their peer group wanted to copy them.

There's also less social norm or expectation to get married and have kids. Perhaps for many in my society it was just going with the flow?

Watch high-influence people (that others wish to emulate) and how many are bragging about their baby? Passé.

That was the stated purpose of a patent.

The modern purposes of patents seem to have shifted a long way from that.

I wonder how much of ADSL's advantage is due to trade secrets (spread across many vendors) versus how much has been published as patents.

> Socialism's track record is pretty bad

However the track record for developed countries communally sharing "intellectual property" is much much better. Universities, open source, and public domain all have some crossover with the ideals of socialism.

Yes, communism has repeatedly failed spectacularly.

The softer socialism of public welfare has worked (so far) for many countries including the US. Although I'm skeptical about the future given modern demographics and our governments' choices to appease a majority. The governments of most developed countries smell socialist to me. I'm from New Zealand and most private income/property is taxed up the wahoo to pay for our social welfare programs: it doesn't take much squinting to see my own society as broadly socialist.

Somehow I see people in the US complaining that the Chinese are beating the US at capitalism (regular complaints of price undercutting and monopolistic behaviours) - what's weird since the Chinese are supposed to be pinkos.

robocat··on AI;DR (AI; Didn't Read)
I am likely agreeing with you: but perhaps I just failed to follow what you were trying to say.

Perhaps it is a wider problem of "flipping the bozo bit", that someone perceives they are being treated as worthless (or worse) and then they respond similarly?

A considered AI response can be good if quoted correctly. Unfortunately I've seen a lot of AI-hate, where even fantastic AI answers (carefully vetted/curated) are shot down.

robocat··on AI;DR (AI; Didn't Read)
You are just collateral damage.

Too many people put up a lazy comment when it is clear they haven't thought about $it, googled $it, or asked AI about $it. Where $it == {whatever they are unsure about or arguing about}.

The lazy commenter desires a human to waste their time writing a response. Often others judge that the commenter doesn't deserve the time or effort, so instead of a thoughtful response others often just reply with a relevant link - giving the commenter a chance to learn or reply.

Unfortunately offhand responses like LMGTFY become a common behaviour in forums, even when wildly inappropriate (as you note).

When it happens to you, it isn't personal, you are just a victim because everyone has been trained to a pattern of behaviour by thoughtless commenters.

It is also likely your comments get pattern matched as not worthwhile reasoning clearly to. You can do something to change your writing to avoid appearing waffly/bullshitty/unworthy (or whatever the reason responders are not replying to the meat of your point). Here's where I've done that pattern match in the past although usually spent time writing reply too: https://hn.algolia.com/?query=by%3Arobocat%20duckduckgo&sort...

robocat··on How to put 170 atoms in an atom
So I thought of a nice question: how close-in does the hydrogen in Rubidium Hydride sit. For gaseous RbH and thinking in solid spheres instead of clouds:

  The bond length of RbH is ~4.5 units.

  The Hydrogen proton is *inside* the empty 5s radius (~4.7 units).

  If we added an electron ("an antibonding electron") it would go into the 5s orbital. But that stretches the bond making the distance between the nuclei ~4.8 units.

  In RbH, the Rb atom gives up its single outer 5s electron to the H atom, so there is no populated 5s electron shell in a Rubidium Hydride molecule.
robocat··on How to put 170 atoms in an atom
Isn't there some hand-waving going on here?

The outer orbital is being treated as the last layer of an onion and the atoms are "inside" that. But orbitals are not spherical so our geometrical intuitions kinda fail.

Edit: Sorry for unclear wording: well, s-orbitals are spherical overlapping probability clouds, but they are not shells like an onion. Nor are they spheres as we commonly think of the geometrical object. To say something is "inside" a probability cloud gets difficult. Disclaimer: my memory/understanding of physics/chemistry/probability is poor. Edit 2: when orbitals of atoms overlap for molecules, don't the orbitals get funkier shaped probability distributions? Surely the same thing happens here and the cloud shapes would change - orbitals are not independent things you can just smoosh together or overlap willy-nilly due to qwuantum blah blah.

Look up some post-mortems on engineering failures in your country that caused deaths. Pick something big like a dam failure or a large building.

I'm no wonk, but too often major failures have seemingly small consequences.
