hdivider··on Complex systems emerge from simple rules
Look at it this way: life on Earth is composed primarily of C, H, O, N , and a number of trace atoms.

If life evolved here on Earth, then somehow, CHON+trace all self-organized into all of Earth life today, including us, and all we humans have done and will do in the future.

Now: say we could go back just before life evolved. Even with very very good data, and with whatever talent (AI, science, anything) and technology from today, would we be able to truly describe the emergence paths for those CHON+trace atoms?

Impossible. This would be far beyond our level of science and technology. We can't even do this for much simpler systems and shorter time horizons. You'd have to predict the emergence of life, the full properties and behavior of all forms of life in the last 4 billion years, and last but not least, humans and all that humans have done and thought since then.

Yet clearly nature emerged all this from perhaps small amounts of 11 elements or so. Complexity is one of the greatest unknowns in our present civilization.

hdivider··on AI method rapidly speeds predictions of materials' thermal properties
This is where most of the real value of AI actually lies. The scientific and engineering applications of machine learning.

Another MIT study: if we AI-augmented R&D widely in the US, our productive economic growth rate would double. The authors argue this would be permanent, forever increasing the rate of technological progress:

I bet a true accounting of all the economic impacts of semiconductor technologies will show these have far more value than Meta, Instagram, Snapchat, TikTok all combined. The stuff built on top of deep technology has higher PR value -- but the deeper tech has far more economic value. Same with AI.

hdivider··on 200 people charged in $2.7B health care fraud crackdown
I wonder: would this level of fraud occur if the US had universal healthcare, or its effective equivalent?

Asking out of genuine intellectual curiosity, not with political or other overtones (even with the highly political character of the news today).

hdivider··on A Study Says Warp Drives Might Be Real–and We'll Find Them with Lasers
Indeed! And as a European, I find it even more curious when Americans take this more cynical stance.

I mean, what have we come to, when a European will go and take a risk, for a chance at an awesome discovery, and an American dare not? ;)

The explorers who first went sailed into the deep Atlantic, with unknown seas and lands beyond, were full of doubts too -- but they did it anyway. Because they had to. In our time, we humans have to continually rekindle our explorer spirit, no matter how settled or distraught our ambient culture becomes. We must explore, with optimism and willpower -- and yes, with plenty of intellect and skepticism too, but end with optimism -- precisely in order to solve the actual problems our world faces.

hdivider··on A Study Says Warp Drives Might Be Real–and We'll Find Them with Lasers
On HN, comments meant to stimulate optimism and willpower don't tend to get encouraged. Cynicism, skepticism, figuring out how things will fail -- as they inevitably will, of course -- or how if they succeed, they're corrupt or broken in some way...that is increasingly the coin of the realm here. :)

In reality, your sentiment is correct. Sure, there are laws of physics. But they are also unknown, as the ones humans understand don't describe all observed phenomena by a long shot. There are still restrictions even so, but incredible unknowns await us. As they always have.

What engineering-minded folks frequently don't understand is the need to apply sheer old willpower, after using all that intellect. Ending with a positive, with the notion that it can be done; we just have to figure out how.

hdivider··on What is ZIRP, and how did it impact the startup world? [video]
My view: look at most of the real problems we face today. They require solutions consisting of:

1) Engineering (what software folks call hardware), especially cross-functional engineering across several fields, such as chemical and electrical.

2) Software, typically including applications of ML.

3) R&D. Research And Development, folks. The thing investors don't want you to do.

Those types of companies will almost never come out of venture capital. They start with a small founder investment (what VCs tell us is called 'bootstrapping'), significantly supported by federal government grants and contracts (the best source of funding for true R&D), and then product development and commercialization.

The ZIRP-era of pure software, VC-driven type of technology entrepreneurship tries to skip all the way to the end, scale beyond all bounds, and exit big and fast. No wonder we're experiencing groupthink, and why the Bay Area is hollowing out: in this form of technology entrepreneurship, there is no deep economic basis for growth.

In short: technology entrepreneurs should take on technology risk. That means raising capital late, not early, because investors will always be skittish about R&D and longer timeframes. And it means following your own vision first and foremost, rather than letting venture capitalists define how you see the world.

Investors are not where the action is. It is founders and early employees who built the likes of Sony, Qualcomm, General Atomics -- each of these, a real technology company.

hdivider··on Silicon Valley's best kept secret: Founder liquidity
Bad founder behavior is quite prevalent and should be called out for sure.

I disagree though with the general notion that employees are taking similar or even greater levels of risk. If you get a stable monthly paycheck, and the reasonable worst case is you're laid off because the company runs out of money (or downsizes), then the risk is in finding a new job.

That situation exists in a job at a large company too. Founders however are so tied to their ventures, that getting a new job is effectively out of the question, because it very likely means the death of the company.

And starting a company is an exceedingly difficult, stressful, and sacrificial thing to do. There is a clear and significant asymmetry in risk, and frequently in blood, sweat, and tears. So the nonlinear rewards should be commensurate too.

hdivider··on No one buys books
Main value prop of physical books for me: guaranteed zero interruptions from the book itself. Worst case, the pages stick together, or pages are missing, or damaged, or other very infrequent causes of distraction.

All modern digital systems are by comparison, distraction machines. You never know when the next interruption ('notification') gets surfaced, the next update, the next forced restart, the next bug, the next battery problem, the next broken or lost charger cable.

Physical books require light, the book, and your mind. All else fades away, and your mind is given free reign to ponder, to consider, to deliberate. No wonder civilization flourished whenever the physical written form was embraced at sustained scale.

hdivider··on Why is everything based on likelihoods even though likelihoods are so small?
One might perhaps say that what is probable

Is that men experience much that is improbable.

hdivider··on CNC lasers for cutting and engraving
Interestingly, if you're doing CNC laser cutting as a business, with the larger CO2 laser cutters, you're gonna spend a lot to keep replacing those CO2 laser tubes. Because the gas degrades with heavy use, even if the tube is intact.

Why can't you just refill the gas? Because the precise gas combination that makes for a stable, reliable laser tube was monopolized ages ago.

Because of that one trade secret, countless tubes end up in the trash and way more than necessary are manufactured. Classic case where monopolization of scientific knowledge can end in significant unnecessary waste.

hdivider··on Extremely high-energy particle detected falling to Earth
Regarding an ET source: some key questions to consider:

What kind of technology would produce such ultra high energy particles?

What would they use such technology for?

Can a technological source be inferred from the data we already have?

It could also 'just' be a new particle which behaves differently than anything on the board. (Would still be a VERY strange particle though for sure, and still leaves open the question of what produced it.)

hdivider··on The story of titanium
This is cool. Thanks!

In my mind, this is what real technology entrepreneurship looks like. As opposed to the latest crypto or social media thing.

hdivider··on The story of titanium
That's why I said titanium alloys specifically. With such a large-scale industrial transformation, definitely many alloys would be explored, to fit the needs of new industries. We don't use pure iron for any serious applications either.
hdivider··on The story of titanium
Huge fan of Titanium.

If only we could find a cheap way to get the metal out of titanium dioxide. Like a Haber process-level breakthrough.

Then we could start replacing steel with titanium in many applications. Think entire freight trains, cargo ships, containers, cars, trucks, tractors -- all that heavy steel replaced by titanium alloys.

Enormous quantities of fuel and energy saved by lower density and higher strength. In many applications, it would likely make stainless steel obsolete.

Trillions of dollars of value may be locked up in such a breakthrough.

hdivider··on We have reached an agreement in principle for Sam to return to OpenAI as CEO
This, 100%.

Sam pontificated about fusion power, even here on HN. Beyond investing in Helion, what did he do? Worldcoin. Tempting impoverished people to give up biometric data in exchange for some crypto. And serving as the face of mass-market consumer AI. Clearly that's more cool, and more attractive to VCs.

Meanwhile, what have fusion scientists and engineers done? They kept on going, including by developing ML systems for pure technological effect. Day after day. They got to a breakthrough just this year. Scientists and engineers in national labs, universities, and elsewhere show what a real commitment to technological progress looks like.

hdivider··on Maine's constitution has unprintable sections
Even better approach: do it like the British. An 'unwritten' constitution. No need to even have a document for the plebs to read and criticize. Whatever gets a majority in Parliament ends up being the so-called constitution.
hdivider··on ChangeDetection, monitor any website change
I have to counter yet again, apologies. :) SBIRs yes are considered grants, but I've seen the same phenomenon for e.g. CRADAs and OTAs. Functionally this is all similar: we find them often on bad gov websites, and an automated tool to track changes can greatly help many companies to win them.
hdivider··on ChangeDetection, monitor any website change
Yeah it's probably true that such things are the exception. But for a startup, a chance at e.g. a $256k SBIR Phase I and then $1.9M Phase II and the modern follow-on options in e.g. the Army (called the CATALYST program and other things) -- this one exception turns the company into something real.

So because the amounts are large (compared to commercial, in terms of when a customer first buys from a small company), those cases really make a huge difference.

hdivider··on ChangeDetection, monitor any website change
This I am afraid is not true either, though. I know many dual-use companies who discovered an RFP (not just on SAM), late -- i.e. with a proposal deathmarch -- and got through.
hdivider··on ChangeDetection, monitor any website change
Good stuff. Niche idea for ya: consider government contractors. Gov sites tend to be atrocious. Manual change tracking can mean you find a $1M RFP weeks earlier, which increases chance of winning. (Consider mda.mil. There's no email signup. What they consider a 'newsletter' is in fact a list of PDFs hosted on their site.)

And that's federal gov contracting. State/local is even more of a Wild West. So much so that many, maany companies just never have the bandwidth to even find RFPs and navigate those ancient sites.

hdivider··on Duet AI for Google Workspace Now Available
"$30, at least for large organizations."

Hopefully they'll make it like $5-$10 for small teams.

Or maybe not 'hopefully'. If they don't, a better and cheaper alternative will probably appear. LLMs are slowly being commoditized, thankfully.

hdivider··on As a psychiatrist, I diagnose mental illness, and help spot demonic possession (2016)
"Is it possible to be a sophisticated psychiatrist and believe that evil spirits are, however seldom, assailing humans? Most of my scientific colleagues and friends say no, because of their frequent contact with patients who are deluded about demons, their general skepticism of the supernatural, and their commitment to employ only standard, peer-reviewed treatments that do not potentially mislead (a definite risk) or harm vulnerable patients. But careful observation of the evidence presented to me in my career has led me to believe that certain extremely uncommon cases can be explained no other way."

It's curious how we humans fail to remember that we're not able to generate all explanations just by thinking about them. Getting to explanations requires experiments. But spirits and demons are so vaguely defined that we just can't test their existence empirically.

Hence, in my mind, this should be in the realm of metaphor, not science. Let spirits and demons live in the humanities, so they can continue to inspire art, books, games, and much thought. They're about the internal human experience, not external reality.

hdivider··on Launch HN: Wondercraft (YC S22) – Use text-to-speech to create podcasts easily
Thanks, makes sense! Have you thought about targeting Substack-based podcasts also? Given how substack podcasters likely wouldn't need the publishing part.
hdivider··on Launch HN: Wondercraft (YC S22) – Use text-to-speech to create podcasts easily
This is a welcome tool indeed. Question: how would you describe how you're different to Descript?
hdivider··on War Music: Homer and His Iliad
Title reminds me of this true masterpiece:

hdivider··on Pegasus Mail
Exactly. Wish more sites and other bits of software followed this website's philosophy. Once you have that which is sufficient, anything more is waste.
hdivider··on Worldcoin isn’t as bad as it sounds: It’s worse
Imagine sama had put all this energy, capital, and relationship capital into fusion power, instead of WorldCoin. Beyond Helion.

It would be easier to accept him as someone who is genuinely altruistic. Instead, he turns out to be just another self-serving 'tech' bro.

I write 'tech' because clearly this guy does not actually care about pushing technology forwards for human good -- which is the cause, in my view, of all real technologists. It's about himself, just as it is with the great Technoking.

hdivider··on Tesla created secret team to suppress thousands of driving range complaints
"The directive to present the optimistic range estimates came from Tesla Chief Executive Elon Musk, this person said."

"“Elon wanted to show good range numbers when fully charged,” the person said, adding: “When you buy a car off the lot seeing 350-mile, 400-mile range, it makes you feel good.”"

Yep, the great Technoking's narcissism manifesting itself in critical technology decisions. Hopefully the ongoing stories of severe mismanagement at Tesla will show people that severe personality flaws matter, especially in technology.

hdivider··on At this company, we are family
Yes, sadly HN does seem to have a high proportion of folks who don't seem to understand the value of human connection. Everything is about technology.

But not all mission statements are meaningless, and not all attempts by executives to create a family-like culture come from a bad place.

Much of it comes from a good place, and it often works. But people who experience this I think are less likely to write on HN.

hdivider··on The “three things” exercise for getting things out of talks (2011)
I wonder: if we were more peripatetic about talks -- meaning, if we walked, in a group, rather than all sat down -- would we still struggle to get so much out of talks?

We sit wayyyy too much in business and tech. There is not nearly enough movement. Yet our bodies are built for movement, not for sitting on our duffs for most of the day.
