arpinum··on How credit card rewards became a $9.2B wealth transfer
EU only capped fees for 4 party systems, and only for consumer credit cards. business credit cards and 3 party systems (American Express for example) are not part of the cap and you can get more rewards with these card types.
arpinum··on Apple announces changes for apps in the European Union
> Web distribution, which is available only in the EU ... require every alternatively distributed app to go through Notarization — a baseline review focused on basic functionality and protection from serious threats.

This is quite a big change for EU users. What I don't understand is how Apple will track the new 5% commission for web distributed apps. You do need to register for the programme, so maybe that is one way they track businesses and get a right to audit their books.

arpinum··on Government sponsored study on alcohol doesn't stand up to scrutiny
Dose makes the poison. And some substances are beneficial at low doses and harmful at high doses.

Do you foreswear aspirin?

arpinum··on Premier league bans gambling sponsors
It's a response to laws that prohibit advertising of alcohol in certain countries at certain times of the day. There may be a trend towards these products, but the prohibition prompted the advertising change.
arpinum··on Premier league bans gambling sponsors
Same with the drinks companies, they switched to explicitly advertising their zero alcohol beers.
arpinum··on Codex Security
I set --max-cost to 100, it bailed before finishing. Unknown if I would get full results for $105 or $500. Either way I lost $100.
arpinum··on SQLite Is All You Need
I use a in-memory database per unit test with both rocksdb and sqlite, it is a game-changer to get better quality tests.

Overall premise is wrong though. Moving the database out of process will change performance characteristics and data architecture too much and will cause massive headaches at exactly the time when you are trying to scale with success. You should have out of process performance tests early to catch these issues, even if you do deploy a single node.

If success can be satisfied with a single node and you are satisfied with availability and recovery that gives you then great, but it isn't all I need.

Starlink is popular in rural England. Trenching fibre to farmland isn't economical and poor DSL is often the only other option.
arpinum··on PostgreSQL Benchmark: AWS RDS vs. Self-Hosted on Hetzner (2026)
Red flags: - Tests Postgres 16, not 18. - Uses t4 burst instances in AWS, shared CPU in Hetzner. - Test fits in memory. - Fails to say if load generator is in same AZ. - Says their own service "includes a standby and automatic failover" but their docs do not describe this feature or its details. - Says to treat on-demand AWS EC2 price as the floor, does not consider savings plan. - Their own service describes automatic backups as a potential future feature.

Me above:

I'm also British, so DGAF about outcomes.

Jurisdiction has multiple concepts, you are thinking of territorial jurisdiction. There is also personal jurisdiction, feudal jurisdiction (serfdom), political jurisdiction.

Thomas is reacting to Roberts. Roberts spends time talking about the king's obligations to those born on their land. There is also each person's obligation to the king. Roberts wants to say "we inherited common law, and under common law everyone born on the king's land immediately came under his jurisdiction, the king owed things to these people immediately (and the people owed the king)". Thomas is saying "no kings".

> What a load of nonsense.

Or, this is a complicated, multi-layered concept that goes back through 500 years of common law. It will look messy.

"subject to jurisdiction" does not mean "has to follow US law", that is territorial jurisdiction. Subject to jurisdiction means political jurisdiction and allegiance. That is why children born to members of Native American tribes (no matter the location of birth) were considered not subject to jurisdiction because the parents held allegiance to their tribe. Read United States v. Wong Kim Ark (1898).

I don't have an opinion on the legally correct answer, reading the full decision and dissents I'd give a slight edge to the majority.

> The 14th amendment grants Jus Soli. End of story.

But it isn't the end, it then qualifies who gets Jus Soli. And that is the debate.

> The people who drafted the 14th and ratified it were in favor of Jus Soli

Thomas cites Sen. Howard and Sen. Trumbull statements in support of the claim that the 14th amendment ratifiers did not intend to grant universal Jus Solis. Is he a liar?

> ... and Kavanaugh are all hacks for going further back into history than the drafting of the 14th

Kavanaugh doesn't go back further into history, it seems like you didn't read the opinion. He spends very little time on the constitutional question.

arpinum··on Supreme Court upholds broad conception of birthright citizenship
You didn't read the decision, it was up for debate in 1898 Wong Kim Ark. Every justice cites it. Wong Kim Ark gives 4 exceptions, and it isn't clear if those exceptions are comprehensive or not.

And you didn't read the majority's breakdown of `subject to the jurisdiction`'s historical meaning, otherwise you would know that the power to arrest is not the same concept.

You have made false claims and appears you are commenting on something you haven't read.

arpinum··on Supreme Court upholds broad conception of birthright citizenship
The debate is whether the USA is a Jus Soli (no s) country.

Roberts claims Jus Soli applies to the USA by looking at historical concept of the words in the constitution and the king's obligations to those on his soil. He cites historical statements by founders.

Thomas and Gorsuch rejects Jus Soli applies since it is a concept from feudal lords and serfdom which the USA did not inherit. The cite historical statements by founders.

Kavanaugh thinks congress gets to decide the meaning (within reason), so he rejects Jus Soli as well.

Jackson worries about backsliding and using this to oppress people, unsure about her legal reasoning, but seems to guess at how authors of the amendment understood the words. I would still classify her as saying USA did not inherit Jus Soli, but later codified it via amendment.

"subject to the jurisdiction thereof" is not a clear statement.
arpinum··on Supreme Court upholds broad conception of birthright citizenship
> All persons born or naturalized in the United States, and subject to the jurisdiction thereof ...

It's the second part that is in dispute and is not clear from the constitution's text what exactly it means and who it excludes. And yes, it has always excluded some people born within the borders, it is not a meaningless statement.

arpinum··on Apple raises prices of MacBooks, iPads
Building a new memory fab takes 3-4 years, extremely capital intensive. Micron is spending $25B+ on Capex and more than half of that is for new memory capacity, a 3x increase over 2 years.

It is a very risky business, overestimate demand by too much and you go bankrupt. And yes, it is hard, especially HBM. Fabs are scaling up, but it is hard to estimate demand in 2029, and it may be better to not overshoot.

They also need to get in line to buy ASML EUV tooling, and ASML has to deal with scaling for their suppliers as well. There are tons of bottlenecks and complexities.

It is a commodity in that there are standards, not that there are many firms that can hit the standards.

This isn't gouging, this is bidding on fixed quantities and bidders having a high willingness to pay. Think of it like an auction.

arpinum··on The Future of Email
BIMI certificates cost over $1,000 / yr right now. For me that's a feature. I wish the fallback in my mail client was a big untrusted symbol rather than sender initials when they aren't in my address book.
arpinum··on I'm Eric Ries, author of "The Lean Startup" and new book "Incorruptible" – AMA
Eric, do you recommend, as you hinted in the book, that half of board seats should be appointed by a workers council? Do you think Six-Sigma is net destructive to a company, and why? Which examples in your book do you recommend readers further research and understand?

I read the book last night. While the topic is important, I was disappointed in the content and format of the book. Scatterbrained. Some of the most important questions get a page of content. Scores of offhand comments and examples that get no serious treatment, sometimes contradictory. The topic would have been better served with less examples.

arpinum··on I'm Eric Ries, author of "The Lean Startup" and new book "Incorruptible" – AMA
Q3: Direct question: Have journalists and their industries been similarly corrupted from their proclaimed mission to communicate the truth? Do the issues in other groups of people (charity, religion, sport league) share the same root causes, or is the source of corporate corruption unique or at a different scale?
arpinum··on I'm Eric Ries, author of "The Lean Startup" and new book "Incorruptible" – AMA
My book arrived today.

Q1: You have done a few friendly interviews on YouTube, but I haven't seen one that challenges you much. Do you know if there are upcoming interviews that you found pushed back?

Q2: Is the idea of shareholder supremacy fundamentally at odds with your with your preferred alternative governance structures, or is it just a time preference and risk attitude issue?

Q3: You will get sympathetic ears easily due to the subject matter. But the same book about non-profits would be a harder sell. Do you agree, and if true does that say something about the marketplace of ideas?

This is more likely due to the digital markets act that requires them to open their platform to competitors. hence it only being restricted on phone and iPad.

How many watts is that setup? Cool you got it to work, but maybe only useful for vintage / retro computing rather than practical if the energy consumption makes it economically wasteful.
arpinum··on Goodbye Visa and Mastercard: 130M Europeans switching to sovereign payment
I have not heard about UK Open Banking rails for merchants being popular. You are talking about P2P? the article is about challenging Visa/Mastercard.
arpinum··on Goodbye Visa and Mastercard: 130M Europeans switching to sovereign payment
This is the EU equivalent of Zelle, but pushing into merchant payments and owned and run by the banks.

When the telcos tried to compete with the cloud providers by offering OpenStack they learned the business wasn't as simple as offering 10-15 services with some racks. I can imagine the same hidden complexity for payment rails

On the other hand regulations have taken too much power away from merchants and Wero could succeed with more merchant friendly terms. They are doing 3-legged payments so they are not subject to as many European regulations as Visa/Mastercard.
