In past eras they used holograms and watermarks and special papers in an attempt to prevent forgery but these methods keep getting challenged by an ever more sophisticated criminal element. Moving into cryptographically secure methods is the last barrier here.

They could also rely on the state to match identities to tickets, but this approach does not scale and is frankly undesirable for the majority of people anyway.

Even if we could make them truly unforgeable, people generally want electronically transferrable tickets. How do you propose to do this?

Having a non-exfiltratable bearer token is really really hard. In order to present a zero-knowledge proof of the possession of a token you need to have some sort of challenge-response protocol. The simplest one, and the one in most common use (such as this) is a time-based method, where the shared knowledge of the current time represents the challenge.

The other method is to use civil identity as the challenge, and use government-issued IDs as the bearer token that the ticket is tied to. This doesn't scale well to larger events, and presents real challenges involved centralization of ticket exchange.

You can argue whether or not forgery is a significant enough problem to be worth this trouble, but that's a business decision, and as live events like this get more expensive forgery and resale become more and more of a problem, which end up locking out people like this who have legally and legitimately bought tickets but can't gain access to events because someone has stolen and resold their ticket.

EDIT: I know complaining about downvotes is a downvotable offense itself, but I'm genuinely curious as to what is objectionable about this comment.

The other side effect expression here is the equals operator; once again, this should not be an expression but should just be a statement. Once again this is used (intentionally) mainly for compactness and unintentionally used to create messy bugs. I do find the "yoda" style checks to be aesthetically unpleasing so I'm party of the problem here.

Maybe it's time to add `-Wno-crement-expressions` and `-Wno-assignment-expressions`. `-Wparentheses` gets you part of the way to the second but even the legitimate uses are ugly to my eye.

But I have one big question -- why aren't the "middle" keys replicated on both sides of the keyboard? That is, for example, why not have two 'g' and 'h' keys? There are always times when you have to adapt; when you're holding down a tricky combination of alt-ctrl-shift keys or something where on a flat keyboard one would just reach with the "wrong" hand to hit a middle key; why not just replicate them?

Honestly a lot of this is that I hate Lua. With so much of the infrastructure moving in that direction it's basically unavoidable. XDG support was honestly one of the things holding me back; I'm glad that this is finally fixed.

There is a line where this becomes truly frightening behavior; where you have to keep your head down and avoid eye contact because they might fly off the handle for no reason, like crazy homeless people on the subway but with badges. So far I haven't seen anything approaching this.

The second one is [1] Jacelynn Guzman, age 23, who was mistakenly identified as part of a targeted immigration enforcement action. She fled the scene after agents approached her and identified themselves. A suspect who flees is likely to be chased -- this does not seem strange or off-putting to me at all. I think notable, for what its worth, is that they did not ask her father for ID or question his citizenship in any way; they were there for a targeted operation and he was not the target, so they left him alone while they attempted to verify the identity of the suspect that they were targeting.

Yes, there may be more of them, but in this particular article that was the most that they could find, and they were clearly trying to find them -- they even include 130 stops that they themselves say are of people who were obstructing or interfering with ICE operations. This is not good, but it's a pretty far cry from bystanders being harassed on the sidewalk for having an accent or the wrong skin color.

Link me a better source that describes or accounts the number of these stops and I'll update my comments and move my priors appropriately.

While disturbing to listen to, without context, I don't hear anything to substantiate the claim of ICE agents menacing anyone they come across.

All the videos I've seen, [1], [2], [3], for example, from a quick check, are ICE reacting unprofessionally and with excessive force against people who are deliberately attempting to obstruct or interfere with them. Let's not play games here and say that they are menacing innocent people walking down the sidewalk. That's not to say that these assaults are justified or appropriate, but let's start the conversation in a good faith position, and not make up bullshit about ICE walking around menacing innocent bystanders.

Having a source that makes a false claim as a headline but refutes their own claims, while acting indignant, is extremely common in a media landscape that wants to signal their "in-group" status.

I think that yes, they should be deported. This is not a punishment.

If your solution is that they should not be deported, but employers should be prosecuted, then you're saying that you want the immigrants to starve.

If your solution is that they should not be deported, but we should extend labor protections to them and force employers to hire them legally, then I think there is some merit to this. This is closer to the libertarian open borders argument, and I once found it very appealing. Entitlement abuse is the main argument against here in my mind.

Because what can an illegal immigrant do? They could in theory just rely on social services and entitlements, but I don't think anyone (including the immigrants themselves, for the most part) really wants that. They want to work, and to make money, and the law makes it very hard to do so legally, so they work illegally.

All the barriers you mention are things that we put in place to "protect" workers, but at the same time create a black market that undercuts those very workers.

As for the employers, sure, they are culprits here, but would you rather have them let the immigrants starve? That also does not seem to serve any social good. As for not paying workman's comp, for example, there is already enough paperwork and bureaucracy involved in hiring a legal worker where there are systems that support and administer those programs. If you wanted to offer a workman's comp lookalike for illegal labor as a social service, then that would multiply the effort and cost by a huge factor.

What I find amusing about this is that it is roughly equivalent to saying that the United States needs to conquer new territory to survive. Need to bring more people under our thumb.

This is definitely "dying empire" thinking.

Worth saying that I do not agree with this. I think in many ways our cardinal sin is that in the interest of legibility (especially for tax purposes) we've regulated our ability to employee people and to get work to an absolutely insane degree. To such a degree in fact, that much of our economy relies on having a source of "black market" labor and indentured servitude in the guise of immigration.

Where we flirt with danger is that we look at one side of this equation, the immigration side, but not the other, the labor side.

Not to mention that hydrogen is free for anyone who has water and a power source.

If we treat the angle where zero lift is generated as the base angle for an airfoil, then all airfoils generate lift depending on their angle relative to that, including a flat plane. As the GP says, other properties are the dominant factor in airfoil geometry.

When introducing airfoils I think it is more useful to start from a plane than a traditional airfoil shape; the math and intuitions are much clearer from there.
