I hope they randomize it in the future like they do it for mac addresses.

GREASE already randomizes the handshake to an extent, and I think whatever TLS stack chrome uses also shuffles the cipher order. In response newer TLS fingerprinting algorithms (ja4?) sort the cipher list first to mitigate this.

I don't think a percentage makes any sense at all. Is it proportionately more expensive to host a $50 game than a $25 game? It's only a percentage Because They Can.

>It's only a percentage Because They Can.

Do you object to other sorts of royalty-based compensation, like for Unity engine or Unreal engine?

Just because you're a driver doesn't mean you get less rights. It means you implicitly consent to the laws covering driving. One such law that (thankfully) still protects drivers? No searching and seizing items from a vehicle without probable cause. You have the right to privacy in your vehicle, with this caveat: they can't search for just any reason, and they're not allowed to search random people. It has to be a specific person, with probable cause of a specific crime.

It's illegal for the cops to put a GPS tracker on your car to track your movements without a signed search warrant. But it's legal for them to place so many cameras that they can do the same thing with no warrant? Bullshit. Recording every single license plate and its movements in perpetuity constitutes a search of random people with no cause. Searching for your specific movements constitutes a search, and therefore must require probable cause or a warrant.

But the law doesn't protect us from this yet, because it's relatively new. When new technology comes out that current laws don't cover, the police abuse it. It's up to us to demand the laws be updated to protect us from this abuse.

It's not any "bullshit" then the fact that police don't need a warrant to follow you. It might be tempting to report with some variant of the "2nd amendment was only intended for muskets" argument, pointing out that the founding fathers never imagined a cop at every street corner, but then you have to deal with all the associated implications. For instance, does that mean first amendment protections don't extend to the internet?

> but he doesn't seem to realize that intent is a thing.

He does realize this. The problem is the police can make up intent just to mess with people. How easy is it fro the cops to say "You purposely splattered mud on you license plate" and fine you or put you in jail. Or even use it as an excuse to pull you over.

> haven't courts consistently ruled that drivers have less rights

This is not about the right to drive. This is about a database of collected data on you that can be searched by anyone. ANYONE.

Except in this case, it'll be pretty obvious that you used a carefully crafted pattern, because it's a custom printed license plate rather the state manufactured one. Moreover, of the list of plausible excuses capricious cops can use to arrest/ticket you, this is pretty near the bottom. Something vague like "speeding" or obstructing traffic (for driving at or below the speed limit, since most people speed) already exists, for instance.

>This is not about the right to drive. This is about a database of collected data on you that can be searched by anyone. ANYONE.

My point is that the courts (and to some extent, the public) have generally accepted that you have less rights while driving, so it's going to be an uphill battle. This is in spite of the fact that I oppose ANPRs.

1. I highly doubt the adversarial image generated by Jordan actually works in practice, especially since it needs to be fined tuned for a specific model, not to mention that different angles/noise will probably break it even more

2. Louis tries to defend whatever Ben's doing by saying that it's basically like random specks of mud or bird shit, but he doesn't seem to realize that intent is a thing. Having random specks on your license plate isn't going to send you to jail, but if it's obvious that you intentionally crafted the specks to defeat the ANPR, that's a whole different thing entirely, even if they vaguely look the same.

3. As much as I don't like ANPR networks or government surveillance, haven't courts consistently ruled that drivers have less rights (ie. "driving is a privilege, not a right")? For instance, the constitution guarantees free movement, but you need a drivers license to drive and police can ask for your license without probable cause. You also can't refuse a blood alcohol test while driving.

I had a professor once ask about the strip of duct tape across the back of my brand new laptop. "Well, thieves cannot pawn electronics with cracked cases. So all my laptops have at least some tape so they think it may be cracked." The next lecture, the prof had a strip of masking tape on his laptop too.

But slap a tux logo and an "i l9ve truecrypt" banner on you device and nobody short of the NSA would even attempt a maid attack.

Can't, or they'll get less money? I'm also not sure if I ever saw a laptop with a cracked case before, not to mention macbooks are the most recognizable and can't have cracked cases (because they're aluminum), and other laptops aren't worth stealing because their value drops sharply.

>But slap a tux logo and an "i l9ve truecrypt" banner on you device and nobody short of the NSA would even attempt a maid attack.

truecrypt is actually very susceptible to evil maid attacks because it doesn't use secureboot/tpm, which means all a baddie has to do is installed a backdoored version of truecrypt and wait for you to enter the password.

Yeah, his website says he's "A Sr. Threat Researcher". It seems extremely unlikely he'd be in charge of rolling out "Microsoft Copilot to 4,000 employees". Not to mention an actual executive would have better writing skills than what's demonstrated in his stream-of-consciousness tweet.

I haven't found any asynchronous IOPS numbers on HDDS anywhere. The internet IOPs are just 1000ms/seek time with a 8ms seek time for moving from the outer to the inner track, which is only really relevant for the synchronous file IO case.

For asynchronous IO you can just do inward/outward passes to amortize the seek time over multiple files.

While it may not have been obvious, I have taken archiving or bundling of assets into a bigger file for granted. The obvious benefit is that the HDD knows that it should store game files continuously. This has nothing to do with file duplication though and is a somewhat irrelevant topic, because it costs nothing and only has benefits.

The asynchronous file IO case for bundled files is even better, since you can just hand over the internal file offsets to the async file IO operations and get all the relevant data in parallel so your only constraint is deciding on an optimal lower bound for the block size, which is high for HDDs and low for SSDs.

Here's a random blog post that has benchmarks for a 2015 HDD:

https://davemateer.com/2020/04/19/Disk-performance-CrystalDi...

It shows 1.5MB/s for random 4K performance with high queue depth, which works out to just under 400 IOPS. 1 queue depth (so synchronous) performance is around a third.

That's the root of it, isn't it? America is pretty great if you're in the upper 20% or so, and otherwise it's losing ground fast.

The bottom 80% is also going to find it hard to move to another rich country. Countries in general want highly paid professionals, not a 50th percentile desk jockey.

can you please explain how these graphics are supposed to support your argument? it's not clear to me and i'm trying to understand the georgist POV.

nonetheless, materials and the cost of labor are the most significant costs for new buildings. not land, taxes, or zoning regulations. here is one example where this is a fact: www.vermontpublic.org/local-news/2024-05-23/uvm-halts-student-housing-project-construction-costs-workforce-shortage

Switch from "national level" tab to "metro level", and select los angeles for an extreme example. Look at the the figures right of the map, that says "share of SFD units build before 1980 with a land share of" and compare the figures between 2012 and 2024. Just by eyeballing the percentages, it looks like the land share went from 50-60% to 70-80%. This is confirmed if you sum up the figures in a spreadsheet, you go from an average share of 51% to 72%.

You can compare this to overall housing prices in the LA area[1], prices in 2024 is 262.7% of 2012 prices. Suppose you have a $100k house in 2012, that will worth $262k in 2024, an appreciation of $162k. Using the land value percentages above, the land value of the houses are $51k and $188k respectively, an appreciation of $137k. That means 85% of the appreciation was in land, not because building materials got more expensive or whatever.
