Interesting post. One detail I don’t see is how the ROE info actually tells you what currency to convert to. I see the exchange rate calculation but how do you know what the final units are?

I suspect it's this part:

"This ticket was priced in GBP, not INR. Because the journey originated in Manchester, the fare is denominated in the currency of the origin country: the United Kingdom."

So: the currency is the one for the country of origin.

The post is “here’s what I do”, not “here’s what you should do and then confront the team about the results.” It’s just showing you a quick way to get some insights. It’s not even guaranteeing it’s accurate, just showing you some things you might be able to draw some quick conclusions on.

I’m not sure why HN attracts this need to poke holes in interesting observations to “prove” they aren’t actually interesting.

It’s a bit reductive to call it poking holes. The author shared his valuable knowledge and I shared mine.

You said this analysis “isn’t strong enough” for an inadvisable scenario you completely invented.

Some of us have watched it ratchet up since the 80’s, when there were no such restrictions. The fact that some people hit a threshold and decide to stop putting up with it isn’t surprising.

To pick a nit, I highly doubt you bought your OS/2 hardware with euros. :D

If I used Escudos it would be useless for the folks reading my comment.

Not so, now I know the pre-EU denomination of Portguese currency

It’s ok. The pedantry was unavoidable.

My iCloud is full. Every once in a while my iPhone nags me to upgrade for a few days in a row and I tell it no and it goes away for 6 months or so. My Mac has never once nagged me about iCloud storage.

I think there’s debate (which I don’t want to participate in) over whether or not invisible characters have their uses in Unicode. But I hope we can all agree that invisible characters have no business in code, and banishing them is reasonable.

I wonder if any other men have your face and your name.

And “find” can easily execute arbitrary subcommands, which may not be readonly.

We need a new suite of utilities with defined R/W/X properties, like a find that can't -exec arbitrary programs. Ideally the programs would have a standard parseable manifest.

I've seen this before with sodoers programs including powerful tools. Saw one today with make, just gobsmacked.

That exists as SELinux.

Did I miss a memo on Linux somehow requiring age verification now? How would that even work?

I thought I saw one about Redhat too, but can't find it.

Laws and lawmakers just concern themselves with making broad "laws" with little regard to specificity and applicability. California, Colorado and Illinois mandate OS "providers" to generate a signal. It is a copy pasted bill with little grounding in reality but a lawmaker is not going to say no "protecting children".

Pushed by AVPA - a group of companies standing to profit from this: LexisNexis, some Thiel corp, etc.

California's law explicitly requires the system and apps to take the user's word for it and not use other information to determine age, which more and more feels to me like kind of a brilliant move to cut the legs out from under other attempts to use the same for surveillance while still satisfying all the surface-level "protect children" sound bites.

You missed US states competing on setting up age verification legislation that lets anyone sue any developer who produces systems that don't do age verification for life-destroying amounts of money.

So, Linus? Patrick Volkerding? I mean, I can build a Linux system from basically nothing.

Eh private prosecutions and third party standing are generally disfavored to such an extent that sure, attention-whoring legislators will propose it, but whether it even passes constitutional muster on the state level is an open question, and open in every state.

The standing is provided by your child seeing naughty things on the internet.

There was some proposal from California or something to require OSs to enforce age verification, it was discussed in some other thread.

For what it's worth, the "verification" in the California law (not a bill, it's already passed and takes effect 2027) is basically the Steam birthdate popup interstitial. There's explicitly no actual link to any outside information, just requiring that the system save a value the user sets and then that apps use that value for any age gating.

There was a California bill that would basically require it.

> And Starlink / xAI is going to shoot them into space.

I highly doubt that. They claim they want to shoot them into space, but I don’t believe a word of it until I see it happen (and see it work). It’s no more real than hyperloop.
