In fact the only cities I’ve been to where I felt like I needed to really have my guard up and head on a swivel were US cities. Not that I don’t keep my awareness up in other places but something about the US sets off my spidey senses. NY felt fine but SF, Miami, Buffalo all felt iffy.
*clarification: I’m not saying that SF is the most dangerous city in the world, but of the cities I have been to around the world, it has felt the least safe.
(High up would be: Sao Paolo, Rio, Bangalore, Mexico City, Johannesburg, Riyadh, ...)
The swings in Silicon Valley and other parts of the Bay Area have been much less extreme in these regards. Most of the wealth is in the Valley, just more diffuse and harder to see.
The US economy is growing gangbusters but 40+ years of "Reagan revolution" have really taken their toll. That ideology has infused many with the belief that if something is broken it should not be fixed; rather that its problems mean that further intervention will simply make things worse.
Even SF, that supposed "liberal" city (whatever that means), suffers from this sickness.
This the first result from a quick search about it https://www.visitsaudi.com/en/see-do/destinations/riyadh
As they got out of the taxi in front of the hotel, someone got shot further down that same street. They checked in, and went for some food. When they got back they learned the people in the room next door had just gotten all their stuff stolen.
They left right away after that.
Sure this isn't a unique experience, but coming from Norway it was pretty far from what we're used to.
The US is a big place with a lot of diversity. I've been to many US and European cities and they all seem to have sections that are safe and those that are not safe.
Bruxelles, Amsterdam, Paris have welfare. And that attracts the wrong people. I wouldn't want to wander in many neighborhoods in those cities. Budapest, Warsaw, Bucharest, Belgrade, Sofia, Prague are much safer.
the problem in eastern europe isn’t violence. it’s cars.
the deaths/injuries in those specific countries from car accidents is greater than general deaths/injuries in western countries from any reason (violence, cars, etc).

The car accidents problem is real, though ... there's the half-serous saying that accidents of this type are our form of mass-shootings.
TIL I am "the wrong people". Ok then. Have a nice life.
A part of the issue, allegedly, is that the Taliban cut Europe’s heroin supplies when it burnt the poppy fields, and addicts have turned to harder drugs. You certainly see a lot more broken people around, even if they don’t seem dangerous.
Sure, it’s a tad dicey in comparison to other streets in Frankfurt but it’s in no way comparable to what I’ve experienced in SF.
From my experience (I visit multiple times a year as my dad lives there) the homeless people and drug addicts in Frankfurt largely keep to themselves and just sit outside the subway together, albeit taking drugs.
I’ll never forget the fact that the lady in the Thai restaurant I visited literally locked the door and you had to knock in order to enter. Craziest thing I’ve ever seen. I feel safer wandering the streets of Delhi and Meerut in the early hours than SF at noon.
I saw more humanity in an LA bus station, where random strangers traded USB battery packs whilst waiting for the bus, and the bus driver himself breaking his back to haul in and strap down a disabled person to their seat, and waving on the others in who didn't have the right change.
Still, there’s no city like Mumbai in the whole of India. It’s literally got something for everyone.
They have other nice areas too, where the residents can ignore the problems that concentrated in certain neighborhoods. And they continue opposing building up single family home areas.
All major west coast cities have massive disparities and homeless problems.
And even other cities like Phoenix have big homeless problems. But building cities super spread out does serve to make the homeless problem go elsewhere, I.e a downtownish area.
SF the only one I've been attacked and had car broken into. Two separate occasions!
The contrast with the wealth had a dystopic feel.
For those like me who hate abbreviations used out of context, PDX here refers to the Portland International Airport, Oregon. I presume that the commenter really meant the city of Portland, Oregon. Why it is so hard to type extra 5 characters is beyond me.
Not many HN people, especially from outside of the US, can immediately recognize PDX. Besides, the commenter I was responding to used SF for San Francisco. For consistency sake they should had used SFO then. :-)
Not all of those are airport codes. I suppose it’s due to the fact that Portland is just one word, and it doesn’t contract as nicely as the other cities.
And somewhat the same with LA. LA is the city, LAX is the airport. You don't really see LAX used for the city.

> I wouldn't say we always call Chicago ORD, but it definitely happens.
CHI, yes, sometimes.
But never ORD - or MDW or GYY. Although CGX would be hilarious. :)
I've lived in San Diego, the Bay Area, and NYC for extended periods of time, but I don't think I've ever heard someone referring to those cities by their airport codes. Maybe you've lived in different parts of the country?
They're a country without borders that span the globe .. and unless you're part of "the group" (be that C programmers, Ham radio operators, pilots, Code Talkers, et al.) you'll rarely hear their jargon.
In other words, it's _not_ an incredibly common well established convention. Thanks for clarifying my confusion.
Ditto, for example, 'klick' for kilomtre in certain military and gaming circles.
You might argue against "incredibly common" wrt general global population, the counter is that it's incredibly common within a globe spanning subgroup.
You'd fail to make the case against "well established" unless you'd care to argue that jargon of some five+ decades isn't well established.
I dare say there are conventions that you would argue are common that have near zero reach outside of the USofA .. handegg for example.
Anyway I think I'll bow out at this point. I'm not finding this discussion especially enlightening.
Leaving aside that it came up often enough back in the early 1980s when I was working on the first draft of Magma (known then as Cayley) and having discussions with John Cannon, Charles Leedham-Green and George Havas, I would not say that it's as common among mathematicians to use the term as it is among air travellers and pilots to use city codes.
All air travel workers deal with destination codes, generally on a daily basis.
Not all mathematicians work with Abstract Algebras.
> I'm not finding this discussion especially enlightening.
Agreed. Your example certainly struggled for relevance.
Anyway I think most people mean "common" to say "you have some reasonable expectation that it will be understood". That's what I certainly mean. So yeah I think I'll stick with my original point here:

Anyway I'll have to log out after this comment since I feel myself getting dumber. Apparently I don't have enough self-control here to extract myself from this discussion in any other way.
I wouldn't expect anyone to know what BNE (Brisbane) or DAR (Darwin) meant at first value.

Of course Portland, OR would be quick enough to type too
