pjkundert··on macOS Sequoia makes it harder to run not notarized or signed apps
Admittedly, I've done 99% of my development to target Linux, and just happen to use a Mac for its simpler and less time-consuming day-to-day GUI management.

This is the first time I've tried to develop something to target a macOS installation -- and it was a train-wreck.

pjkundert··on macOS Sequoia makes it harder to run not notarized or signed apps
This is not good.

I've spend literally days attempting to get a Python-based GUI application "signed", using every available packaging option and dozens of different approaches recommended by a multitude of different sources.

Absolute failure -- and no usable error messages indicating what might be wrong. Just basically "no, you can't upload that.".

This does not bode well...

pjkundert··on Bring crypto back to currency
One amazing outcome of the (currently expensive and unweildy) DeFi implementations, is that there is always a maker/taker available for every currency pair.

You can always exchange every cryptocurrency for every other cryptocurrency, 24/7, without having to ask any bankster or do-gooder bureaucrat for permission.

Once wealth-backed dynamic-issuance cryptocurrencies eliminate the need for any Fiat on- or off-ramps, the circuit will be closed -- nobody will ever have to ask a gate-keeper for permission to create wealth, monetize that wealth, or execute a mutually agreeable transaction with that money.

Nor will they be forced to use sub-standard money.

The existing power structures will be ... displeased.

pjkundert··on Bring crypto back to currency
The "central authority" that determines the composition of the basket -- is the users of the money.

The thing about non-fraudulent, wealth-backed money is that there is no barrier to entry, nor is there a barrier to exit. Unlike usury-based money, a wealth-backed currency can cleanly decrease in usage, down to zero. People withdraw wealth pledged to created the money, by returning the amount of money created, and then take their wealth elsewhere.

Thus, if people don't like the valuations arrived at by the "basket" underlying the value of each unit of money (ie. something becomes undesirably in/deflationary), they can move to another form of money -- ideally, one that constitutes its "basket" based on a more representative set of the society's basic commodities. In the ideal embodiment, this basket would evolve over time (eg. as energy production moves from coal to oil to natural gas to nuclear to renewables over the years, for example, the energy commodity component of the basket would be revised automatically).

As for the PID loop, there are much more advanced controls methodologies that improve error rejection (eg. Kalman filtering), stability (Model Predictive or State Space control), etc. Furthermore, limits on the introduction (or withdrawal) of wealth (and hence newly created units of money) should reflect the current size of the ecosystem to limit shocks that would adversely interfere with the control stability. (ie. you can't create 10x the current size of the economy in newly issued money all at once.)

pjkundert··on Launch HN: Airhart Aeronautics (YC S22) – A modern personal airplane
Well, some are rated to be able to sustain shocks of 10,000g while powered, and maintain accuracy through lesser shocks that would still vaporize the rest of the airframe, so yes.

I suspect you'd be very interested in this paper:

https://docs.google.com/document/d/1iUscaSy6HHLVz2e2rjQfQtx5...

There are some good reasons why global-consensus cryptocurrencies can't generally be used as money:

pjkundert··on Apple's 'Find My' service" dubbed super creepy surveillance tech"
Everyone who hates you either has or can easily obtain your location.

Find My just allows your friends to see where you are.

pjkundert··on Maduro lost election, tallies collected by Venezuela's opposition show
Hmmm. You sound very sure of this...

Why don't you trust the output of the voting machines in this case, but do trust it in the prior case?

In both cases, there are reports of numerical anomalies that are claimed to be statistically unlikely. One elicits calls for validation, the other elicits claims of "election denialism" for similar requests. Strange.

One expensive laser-ring gyro, or 3+ independent MEMS gyros?

I’ll take the multiple independent gyros, thanks.

pjkundert··on GPU Restaking – Beyond digital currencies to physical computing resources
This is a great idea; this is what Holochain and the Holo project are doing for all of your compute, bandwidth and storage, and could quite easily be extended to specific types of compute such as GPU as well.
pjkundert··on Apple Intelligence beta flagged a phishing email as "Priority"
Huh?

An LLM can be trained to actively check that every email comes from a domain controlled by the claimed author of the email. That DKIM signing was successful from the purported issuing domain, and so on.

All of the stuff I do when grandma calls asking whether an email is legitimate.

We should have LLMs trained powerfully in detecting signs of these attacks -- after all, we have literally trillions of training examples stored!

pjkundert··on Belenios: Verifiable online voting system
Use homomorphic encryption to allow a voter to create multiple “valid” keys from their root key, and sell those votes to as many people as they want! Provide instructions publicly on exactly how to do so.

Then, the voter can vote using their root key, reversing all the sold votes and cast a vote for their preferred candidate.

Vote selling problem solved.

pjkundert··on San Francisco to ban software that "enables price collusion" by landlords
"price fixing algorithm"? Wow, that's quite a feat! An algorithm that convinces all individual property owners to collude to set a price? So persuasive, it is, that there are no property owners making things available at differing prices?

"access to non-public information"? What, like the market price of your own personal property, and that the algorithm proposes that you should rent it for a price that yields at least the payment of a mortgage on the property! Magic!! Sorcery, I say!

This line of reasoning is amazing.

pjkundert··on Priced out of housing, many younger disillusioned voters embrace populism
Uhm, no. Nobody believes economic migrants are making homes unaffordable. To claim so is just silly.

Politicians importing millions of economic migrants and supplying them with a home? Yup, that will probably cause an issue.

Which is exactly what is occurring.

The feigned "shock" of Politico and other mouthpieces for the political elite literally orchestrating and funding this is comical. Muh populism! Beware!

History's real journalists must be spinning in their graves...

pjkundert··on Elon Musk's Private School in Texas Starts Accepting Applications
Many home-schoolers use “Gather ‘Round” curriculum materials. They support you in educating a wide range of different ages in the same class.

It works spectacularly well for home schoolers. It could work well for mixed-grade classrooms.

After all - almost nothing could be worse than what we’re doing in public education, right now…

pjkundert··on San Francisco to ban software that "enables price collusion" by landlords
"dictate". I think that word doesn't mean what you think it means.

If I, as a property holder, personally decide to use some mechanism to assist me in reaching a price for my product, that is fine -- even if you don't like it.

If I, as a property holder, meet with all of my fellow property owners and collude to set a market price (eliminating competition), that is not fine -- that is collusion.

Are you claiming that all property holders are literally colluding to establish a price that eliminates a market price? That there are literally no people who decide to set other prices for equivalent products in that market? If everyone in a market decides (with the help of a program, or because they can do basic mathematics) to set a higher price, and some people, like, just read the "for rent" adds and set similar prices -- that they are, literally colluding to set prices?

Because that sounds crazy. What this actually seems to be is the market establishing a price based on common knowledge.

If crazy banksters and treasury-looting politicians decide to cause massive inflation, crash the house building industry, and higher rent prices are one (obvious) result, I think we should perhaps look to the root cause -- not accuse some poor slobs reading data from a spreadsheet and setting a rent price that recovers the true rental value of their property, of collusion.

pjkundert··on San Francisco to ban software that "enables price collusion" by landlords
Outlawing an algorithm that observes public facts and make obvious decisions based on those facts seems ... problematic.

If all the same owners downloaded an Excel spreadsheet that imported the data and ran an algorithm to arrive at a market acceptable price, that would also be deemed illegal?

If not, why not?

Sounds like people having fun, doing what they love and being free.

Unacceptable!

;)

pjkundert··on San Francisco to ban software that "enables price collusion" by landlords
Wow rents are going up!

A) encourage more supply

B) prevent landlords from observing rent prices.

Politicians: Let’s go with B! It will totally work.

Highly recommend reading this!

Making it easy and legal for regular people to understand, run, test and modify your software is important.

pjkundert··on Canadian journalism is suffering – but Meta isn't budging
This disproportionately affects independent news organizations; "Big News" like CBC gets billions of dollars a year in funding from the federal government.

So, lobbying to pass this Bill C-18 allows CBC, etc. to entrench their total control over media in Canada, extinguishing all independent media.

The system is working as intended.

pjkundert··on Newly identified bot-like accounts are generating billions of impressions
This problem is probably impossible to solve, without restoring both:

- personal authority over agency/identity (eg. through private PKI credentials, such as produced by HD wallet derivation schemes used for cryptocurrency, etc)

- personal establishment of networks of trust between agent IDs (root public keys), proving networks of known identities with specified levels of trust.

The “networks of trust” of these botnets would then be clearly “incestuous” (few external trust relationships) and thus easily ignored.

Once the value of botnets drops to zero, incentives disappear.

pjkundert··on San Francisco becomes first US city to ban automated rent-fixing technology
Ban the software that monitors rents in the area, and brings your unit into line?

Ya, that’ll work.

pjkundert··on The sinister, shocking rise of dog attacks on postal workers
I don't mind dogs; however, I regularly have to arrange myself between dogs and my daughter, in case they lunge.

How is that something I should need to do?

If I walked around brandishing a weapon and you had to put yourself between me and your daughter, you'd be OK with that?

pjkundert··on [dead]
If the "Economists" responsible for MMT theory, central bank monetary debasement, a global debt explosion, and rampant inflation in the face of decades of productivity increases that should have led to across the board price deflation are "Stumped" -- I'm thinking this is a good thing...
pjkundert··on The sinister, shocking rise of dog attacks on postal workers
I’d like to be able to brandish a dangerous weapon, and occasionally shoot it into the air.

It usually won’t hurt anyone!

It shocks me that dog owners think it’s OK to brandish their barely constrained, dangerous weapon around me and my young daughter…

pjkundert··on Rent Control Reduces New Development: Bug or Feature?
Units that this “rent control” scheme disallows (source; direct, personal knowledge of individuals experiencing each of these scenarios):

- Studio apartments that are rented to visitors in the summer, and students in the winter.

- homes that the homeowner can vacate during the summer tourist season, and either occupied or rent in the winter.

- Homes, which can be divided into two or more Airbnb, that the owner can can vacate because they have a second home.

- all construction made possible to marginal borrowers, that was rationalized by the potential for Airbnb income in a pinch.

- construction of hotel and apartment units, prevented due to that possibility of further legislative interference by government.

- Loss of productive, wealthy, citizenry who could build, who can move to more business favourable jurisdictions at will.

But, you’re willing to bet that none of these will occur, and that the market will not respond to vastly increased housing unit supply with lowering prices and increasing availability.

Is this a bet that you’re really willing to make?

pjkundert··on Rent Control Reduces New Development: Bug or Feature?
Your hypothesis, that AirBnB units are not fungible with long-term rentals, is not sound.

I personally know property owners, large and small, and their properties are fluidly exchangeable between long and short term rentals.

Reducing the production of new rental units will have the obvious result.

pjkundert··on Rent Control Reduces New Development: Bug or Feature?
The cities that have done so are likely to experience the outcomes historically associated with rent controls — disaster.

I’m just stating the obvious.

pjkundert··on Rent Control Reduces New Development: Bug or Feature?
As someone who was considering building a home with a rental suite, and who knows multiple others who were planning to do the same — I can assure you this is an incorrect hypothesis.
