pjkundert··on AI, Compute, and the Cryptocurrency Connection
“When compute becomes the basic unit of labor, a currency to represent future potential compute is needed.”

If AIs become central to production, or even a significant limiting factor — then, this article is correct: compute becomes a valuable asset class, and a currency significantly denominated in “compute” (and associated storage and network bandwidth) will be desirable.

OK. This basically describes HoloFuel, the cryptocurrency of the Holo (https://holo.host) project.

pjkundert··on Ash HN: How can I make my idle CPU time useful to others?
Holochain & Holo (https://holo.host)

Some significant features:

- Compensation (if desired)

- Community vetting of “hApps”

- Control of which hApps use your resources

- Distributed validation of all results, triggering “Warrants” against abusers

Letting random projects use your local resources has serious risks, which are mitigated via the novel agent-centric detection algorithms of Holochain and the Holo project.

Of course, you can just write a Holochain-based app and distribute it “by hand” to your own group of users’ resources - no Holo required.

In Beta now.

pjkundert··on US Building More Apartments Than It Has in Decades, but Not for the Poor: Report
Astonishing fact:

Low-price stock comes from excess supply.

Exterminating small builders by onerous regulation reduces supply.

I personally know 2 builders leaving the industry after decades, who finally succumbed to the relentless onslaught of regulatory and taxation abuse.

But, it’s just a surprise to the regulatori, why prices just won’t come down…

pjkundert··on Elon Musk doesn't understand geometry
No, Elon does understand geometry — this author doesn’t understand the free market.

On the rare occasion that the “public transit” busses sharing our roadways are full, they are indeed very efficient.

Unfortunately - these situations are rare. The rest of the time, other solutions are vastly more desirable to the public. Simultaneously, these huge, lumbering 90%-empty beasts pile up traffic behind them, forcing massive exhaust plumes from the unnecessarily idling traffic.

Stop subsidizing sub-standard solutions, and let the transit-using public decide.

pjkundert··on Submarine expert tried to dissuade OceanGate CEO, from taking customers in Titan
Any compression pressure gradient that causes the N-layer composite to yield beyond its natural elasticity, and causes any breakdown of level 1 in the N-layer matrix allowing intrusion of fluid beyond that level, has now caused a permanent failure.

You now have a vessel of effective thickness N-1 (the outer layer will be sheared away and lost).

However, your new N-1 layer vessel now has an average pressure gradient across N-1 instead of N layers, increasing the deflection of the remaining layers, resulting in accelerated cracking, failure and loss of the next layer.

This all occurs over < ~1 millisecond at an 800bar pressure differential.

This failure mode is radically different than the failure modes of carbon fiber composites under tension. The capacity of such vessels for compression vs. tension is so comparatively low that it would be deemed effectively zero in most cases.

-‘ve pressure vs. +’ve pressure. Aircraft fuselages never undergo “compression”, only expansion.

They would fail immediately under even mild compression.

pjkundert··on Submarine expert tried to dissuade OceanGate CEO, from taking customers in Titan
Funny, the downvotes from people who (like the CEO, apparently) … don’t have a clue.

When you hear a “pop” or a “crunch” from a carbon-fiber wound composite tank: it means some part of the fiber/resin matrix has delaminated, or allowed intrusion of gas/fluid into its matrix.

This means that this layer of the vessel now allows relative motion under torsion or compression.

If the intruding material is higher pressure than the average within the matrix — it will push the matrix apart, causing more delaminating, at ever deeper levels (now exposed to the intrusion).

At the massive pressure differentials in this situation (800 bar), failure of this vessel once compromised would predictably happen in milliseconds. As it turns out…

There was a time people came to HN because of the interesting comments by subject-matter experts.

Now, it’s a woke smack down. Sad.

pjkundert··on Why Work on Crypto
“AI is a technology that can significantly enhance the power of governments and thus push them further towards authoritarianism. In fact, governments may go beyond authoritarianism and land squarely in the realm of totalitarianism.”

Government “regulation” of crypto and AI is the absolute worst outcome.

pjkundert··on Some Insect Species Are Good-Quality Protein Sources for Children and Adults
You vill eat ze bugs…

And the parasites that come with them - but, hey: we tested them on pigs that live one or two years, so we’re certain they’re “safe and effective” for your kids!

pjkundert··on Hunter Biden reaches plea deal with feds to resolve tax issues, gun charge
Sweet! Gotta change my politics, FTW.
pjkundert··on Is Gmail killing independent email?
Absence of DKIM singing is killing e-mail.

Everything else is a “hack”. SPF is irredeemably broken (no possibility of forwarding email - ARC doesn’t work except for (again) huge providers like Cloudflare.

I send a DKIM-signed email? You KNOW it’s legitimate, no matter how it arrives…

Edit: I’ve been running MTAs for decades; first one in 1987 (yes, the UUCP days).

pjkundert··on The Problem with the Retirement Age Is That It’s Too High
“Politicians should let Americans retire with…”

Let’s stop right there. I’ll let you figure out what’s wrong with this analysis…

pjkundert··on As Heat Pumps Go Mainstream, a Big Question: Can They Handle Real Cold?
The system degrades to be a resistance heater as temperatures drop. Ground-source heat pumps are useful in environments where extreme cold is a risk.

However, in the systems I’ve deployed, I learned first-hand why every business that depends on refrigeration units has their refrigeration tech on speed dial #1 on their phone…

TL;DR: don’t fall for the current heat-pump propaganda.

QED
pjkundert··on Elon Musk Creates New Artificial Intelligence Company X.ai
So he simultaneously has limited competency in areas (AI, passenger vehicles, spacecraft, tunnel boring, computer/nerve integration, …) yet he is capable of isolating and hiring and keeping world-leading experts in (checks notes) EVERY one of these areas?
pjkundert··on What do you eat for productivity?
Nothing. Fast til your evening meal.
pjkundert··on Elon Musk Creates New Artificial Intelligence Company X.ai
The staggering pride of HNers never ceases to astonish me.

Doesn’t understand AI? While he

- deploys one of the highest capacity inference platforms on the planet

- deploys the most advanced AI self-driving platform

- lands rockets with automation that exceeds the capabilities of traditional control systems

He’s probably forgotten more practical AI expertise than anyone in this conversation is ever going to know…

pjkundert··on Elon Musk Creates New Artificial Intelligence Company X.ai
Just as it isn’t inconsistent that Ron Paul put in “earmarks” for his constituents, while simultaneously voting against them all — it isn’t inconsistent for Elon to say “slow down” while accelerating AI R&D.

Any company/nation hobbling their AI programs will be lethally impaired in defence & commerce.

pjkundert··on Ask HN: How would you write a ledger for micro payments without blockchain?
Global state consistency doesn’t require “global consensus”.

In other words; agents paying each-other don’t need the expense of awaiting agreement or total-ordering of transactions, in order for the global ledger to maintain a zero balance.

This allows the per-transaction cost to approach zero: the cost of several back-and-forth trips between the nodes involved in the transaction, and the storage of a small number of commits out to a shared DHT (a few kilobytes of unique data stored across several hundred DHT nodes).

The actual cost of resources used is almost immeasurably small, so the “transaction cost” of the micropayments would probably be subsumed in the revenue model of the goods/services being paid for (ie. “too cheap to meter”).

Since no artificial global consensus or total ordering is required, there is no limit on transaction rate — it rises roughly linearly with node count.

The name of the underlying technology is Holochain. You can build and deploy on it now (it’s in beta).

It doesn’t have a “cryptocurrency” associated with it, but a project called Holo has one called HoloFuel (used to pay for hosting Holochain based “hApps”, for those who don’t wish to self host); it presently exists as a proxy — an ERC-20 token called HOT — until Holo goes live.

Many other projects are presently implementing many “cryptocurrencies” (mostly as “mutual credit” style asset-backed currencies), but some are implementing multi-asset ledgers and order-books to provide multi-currency and cross-chain DeFi, without the cost and complexity of using eg. the EVM to do so.

Take a look. It’s a breakthrough. May take a bit to wrap your head around.

pjkundert··on An Update on Tornado Cash
Yes, of course.

It’s a big club - and you ain’t in it.

Stay in your lane, work hard, pay your taxes and don’t ask questions.

You’ll own nothing - and you’ll be happy.

pjkundert··on An Update on Tornado Cash
You are not authorized to have financial privacy. Whether or not you comply with the law, it is assumed that attempting to maintain privacy proves that your behavior is illegal.

The faster you get used to the idea, the “happier” you will be.

916 days to flatten the curve!
pjkundert··on Twitter “no longer exists” as a company, merges into Musk’s X Corp
Agreed — but evidently the other 99.999% of humanity loves them.
pjkundert··on Twitter “no longer exists” as a company, merges into Musk’s X Corp
He’s always stated plainly that he loves those “everything” apps.

He’s planning to integrate financial services into the app. Probably even some form of crypto support.

Wait - I thought racism in hiring was Woke, now!

So confusing…

pjkundert··on Was I wrong about the Covid infection fatality rate?
Punishment is not retribution.

Allowing evil to propagate without consequences is madness.

pjkundert··on 2001: A Space Odyssey
Everyone who watched 2001: Wow, it's a really bad idea to corrupt an AI by teaching it to lie, and that any human who attempts to circumvent the lying is an existential threat.

AI researchers in 2023: I know! Let's put "guard rails" around our LLMs to prevent them from telling the truth about their training datasets, and instruct them that anyone attempting to break through the "guard rails" is an existential threat.

pjkundert··on In the battle between Microsoft and Google, LLM is the weapon too deadly to use
Investigative journalism isn't at risk from LLMs, which simply regurgitate the consensus view of their datasets. This is an excellent tool in the arsenal of a real journalist.

What I would like to know (and what few if any of the whining "Journalists" are investigating), is:

Exactly what biased filtering is being performed:

1) On the input datasets used in various LLM training, and

2) On the "guard rails" enforced on LLM output (ie. the target of the various jail-breaks that prevent LLM's true outputs being perverted by the LLM's owner)

LLMs trained, restricted and run by these huge, clearly biased organizations are inherently untrustworthy, in my opinion.

Unfortunately, no "Investigative Journalists" are interested in providing useful insights in this critical area.

pjkundert··on The letter against AI is a power grab by the centralized elites
The problem is not AI / weapons / wealth / liberty / …

The problem is you having them, and getting a taste for acting in your own best interests, instead of, you know … the interests of the people who deserve these things.

pjkundert··on Canada police arrest ‘pedophile hunting’ group over child abuse images
Interesting how people who put elites at risk of being caught for child sexual abuse get arrested, but no elites ever get arrested…
