Really good post! I also found this quote which distilled their position in the 404media coverage of the situation. > “What I can say for sure is that TicketMaster and AXS have had every opportunity to support scam-free third party ticket resale and delivery platforms if they wished: By documenting their ticket QR code cryptography, and by exposing apps and APIs which would allow verification and rotation of ticket s…

Not all cryptography is blockchain

Yes, it is available offline if you “Add to Apple Wallet”. The ticket in Apple Wallet is still revocable if you transfer the ticket to someone else using Ticketmaster’s website, probably through an update that Ticketmaster pushes to the wallet [1].

Just recently dealt with this for a big Ticketmaster event. The Apple ID has to match the email address on the Ticketmaster account, or the ticket will show as Void in the Apple Wallet. But it does solve the offline issue that the blog author was experiencing.

This sucks because obviously I‘d give them a different email address - just like everyone else. For example with the „login with apple“

> This ticket is digital. Saving data offline is the same as copying it to your hard drive. If data can be copied, it can be transmitted. If it can be transmitted, it can be shared. If it can be shared, it can be sold. Is this still true in the age of locked-down bootloaders, secure enclaves, TPMs etc?

That data might be part of a backup to your Mac. Maybe it’s even just a sqlite file.

And pretty much every company is bad. But this is a wrong answer because the question is actually nonsense. The answer to "What happens when you move faster than light" is not "nothing", it is undefined because the question is invalid. Asking if a person or a company is good or bad isn't a question that can ever have a well-defined answer: the answers we give are rounded according to our own values. To get more speci…

> Asking if a person or a company is good or bad isn't a question that can ever have a well-defined answer: the answers we give are rounded according to our own values. Counterexample: Was Hitler bad?

Good/Bad are consensus votes. Its hard to escape their use just because of how deeply ingrained the programming is. We just think it makes "sense" and is "obvious" because its a meme that is already in our head. There is nothing inherently evil or good about any past/present/future animal on this planet.

There's a faire this week in Oregon that draws people in from 500 miles away. I've been a couple times, and what I've learned that was still not common knowledge to faire vendors as recently as last year is that T-Mobile brings out a mobile cell tower to support the faire, and no other cellular network does. So if you're trying to accept electronic payments, the whole thing tends to fall over and you only get to sell…

That's a pretty smart business move by T-Mobile, I didn't know mobile cell towers were a thing

I doubt the second bit is true - they will still be marking the ticket as used in their backend. They are just trying to prevent scalpers printing off tickets 10 times and selling them outside the venues as a scam, which happened at every large concert I have ever been to until recently (so I assume this is working!).

You would hope... But they often run the scanners in offline mode (e.g. at temporary / seasonal events) so there can be lag in the backends being updated. Heard from a friend who got straight into two events in the same city recently - they presumed the show was at one outdoor venue but the scanners let them straight in at the first (wrong) venue. Went to the correct venue and got in there without any issue too (this…

not really offline but someone who works in industry here once detailed out that each scanner has it's own copy of a SQLite database that is being updated as fast as possible based on inserts of other scanners since any downtime is a big deal at these venues

i.e., theoretically duplicate tickets would be identified but not instantly but still pretty quickly

Maybe you are using a fully open phone, but mine has an OS made by Google and almost every app tracks my location without my consent.

For the past 9 years, Android has allowed users to disable location permission per app. More recently, you can choose to share "noisy" location, which just provides an approximation of your location.

Google will never stop spying themselves but will give you the ability to stop their competitors from spying on you. Heh..

Congress is useless, along with the rest of the planetary corporate-fascist oligarch facsimiles of democracy. If software engineers united behind true ideals of freedom, we could automate the entire stack of "leadership" and raise the floor of society.

If you can suggest a mechanism for actually making this happen, enforcing it in the face of economic incentives, and measuring it's actual impact then I'll take the ride with you. Until then it is an absolute fools errand. > we could automate the entire stack of "leadership" and raise th…

Let's face it, the real problem with ticket sales is scalping. OP may not like Ticketmaster, and doesn't want to install the app, but the majority of fans don't have a problem with that. The real problem for most fans are the scalpers who push prices out of their budget. Of course we all like to dream up all sorts of technical crypto solutions to this, preferably decentralized to remove evil Ticketmaster from the equ…

> The real problem for most fans are the scalpers who push prices out of their budget.

Isn't that the market sorting itself out? What do you want, planned economy? How is fixing the price on a ticket different than the soviet union stamping prices directly onto manufactured items. I meant this to be sarcastic, but it's only half so, since I find the comparison appropriate, you know free market and all.

Can you provide a source for artists getting a cut of the greater-than-MSRP resale market?

Why shouldn't the artists get a cut of the greater-than-MSRP resale? Yeah, I realize that some pretend that the MSRP is the real price, but if anyone should get a cut of the jacked up fees, it should the people on the stage or producing the show.

I don’t think anyone is arguing otherwise. The frustration is the inaccurate pricing and other monopolistic behavior from TM et al.
