NRA is not the only US 2A rights organization, it's not even the most effective. GOA for example defending Pretti's "right to bear arms while protesting", as did the SAF and many others

People freak out if you threaten to take their guns away.

Do they? Because the last time the President suggested it, along with people from the DHS, the best the NRA could muster was a "it was a bad idea to bring a gun".

Odd, that's not what the NRA stated, nor what any media org reported them as saying. So where do you get that so-called "quote"?

Trump was the one who said "it was a bad idea to bring a gun", and here is the NRA's actual response to trump's suggestion: “The NRA unequivocally believes that all law-abiding citizens have a right to keep and bear arms anywhere they have a legal right to be,”.

Comment Re:Anti-copying technology for currency (Score 1) 123

Actually, I thought it was legal in the US to make your own firearm for personal use. You just can't sell it. So why would it be different if you 3D print it vs. fabricate it with some machine shop equipment?

You are correct -- under federal law, it is legal to make your own firearm for personal use (PMF), though manufacturing firearms with the intent to resell for profit requires a federal license (FFL). A few states are trying to pass their own local restrictions on firearms manufacture. Some of these proposed bills, such as in the states of Colorado and Washington, also include CNC machine tool fabrication in their bans.

This specific bill proposed in California is focused solely on 3D printing

Did you know all color photocopiers and printers sold have anti-counterfeiting technology? There are special patterns printed on bills that photocopiers and printers can detect and will refuse to print.

Most commercial printers, copiers, and print engines, but not "all"

So it was solved not by a law, and not by software that looks for anything resembling currency, but rather by placing a simple, easily software-detectable, pattern into all currency, and ensuring that anti-counterfeiting tools treat any currency lacking this pattern as fake money.

Okay, so now we just need to mandate the (mostly anonymous, decentralized) designers of printable gun CAD files to embed these special patterns into their open-source STEP and other CAD files, and then convince the open source printer and slicer software developers to include the detection code ...

Comment Re:Already a Thing (Score 1) 123

This content restriction is already a thing on printers everywhere. Try printing a bank note and see what happens.

The currency detection pattern (The "EURion Constellation") was added to the design of banknotes and certain other documents to enable detection. Good luck getting the printable gun STEP/STL/GCODE people to embed a special small easily-detected feature into their files!

Also worth noting that currency detection isn't a law, and isn't in every printer. The few companies making high-quality color printer/copier internals caved to political pressure and "voluntarily" added detection for a very simple pattern to their firmware. Adobe also embedded this in their (closed source) photoshop software.

Reliable detection of anything that might possibly be a gun or a part of a gun, in any possible 3d rotation, is not a trivial problem, an effective solution would pretty much first depend on developing Artificial General Intelligence (AGI).

Comment Concerned about bandwidth? Use a tarpit (Score 5, Interesting) 43

Back in the day, we used to run "tarpit" SMTP servers which looked like an open mail relay but ACK'd incoming packets only just barely fast enough to keep the remote client from timing out and giving up. The theory was that tying up spammer resources was a net good for the internet, as a sender busy trying to stuff messages through a tarpit was tied up waiting on your acknowledgement, reducing their impact on others.

Similarly, perhaps the right answer here is to limit the number of concurrent connections from any one network range, and use tarpit tactics to rate-limit the speed at which your server generate contents to feed the bot -- just keep ramping down until they drop off, then remember the last good rate to use for subsequent requests.

It would perhaps be interesting to randomly generate content and hyperlinks to ever deeper random URLs -- are these new crawlers more interested in some URLs or extensions than others? If you pull fresh keywords from the full URL the crawler requested, will it delve ever deeper into that "topic"? If their Accept-Encoding header supports gzip or deflate, what happens when you feed them a zip-bomb?

Perhaps the best counterexample of your premise is the Unabomber. Yes, not on the Web--but I think that was half because of the timing and half because he understood the lack of real technology-based anonymity. But he tried quite hard to stay hidden. And died in prison..

Theodore Kaczynski was caught because of poor Operational Security (OPSEC). He let his ego get the better of him, delivering a 35,000 word manifesto and insisting that it be made public.

He was caught only because he thought he was smarter than everybody else, leaving clues with each bomb and in his manifesto. Ultimately the Washington Post's publication of his writings caught the eye of researchers, and more importantly, his younger brother David, who turned him in for the $1M reward.

Generally those traditional crawlers are well-behaved, and will follow the instructions given in robots.txt, though not all follow suggestions like crawl-delay. And if not, they tend to originate from fixed source IP addresses which can be blocked or throttled by the site operator or their CDN.

Back in 2020 IETF released a draft document "RateLimit Header Fields for HTTP" providing rate-limit headers which well-behaved clients should respect.

Higher income families received fewer A's (under the new system).

They seem to be suggesting this is because students from "higher income" families were better able to adjust their behavior to work with the system, including lower absenteeism, turning in assignments on-time, and completing extra credit assignments. Oddly I was one of the lowest income students in my high school, and yet I managed to meet these minimal standards!

Oddly enough, these same behaviors (showing up, on-time-delivery, and going above-and-beyond) are also desirable skills for nearly any employer, thus "Grading for Equity" does a disservice to students by explicitly removing them from the grading equation

Looking at Joe Feldman's defense of GfE, the one thing he seems to get right is his suggestion that a student's grade in a given course should be most influenced by whether she mastered the subject matter at the end than how muchs he struggled with it at the beginning, middle of the term

Just if one other person had won they would have still lost a bit of money. It would be hilarious if two groups did it at the same time, guaranteeing record profits for the state lottery, and also guaranteeing that both groups lose more money than they win.

They spent around $24.5M on tickets (assuming they were able to keep the 5% sales commission), took home $57.8M (the lump-sum payout of the $95M pool).

If one other person had won each winner would take home $28.9M, still a small net profit.

I’m wondering why the 2A crowd is so silent on Hunter Biden...

See also: Philando Castile.

The reason your self-constructed strawman suggests is just your personal biases showing, not the NRA's. Rather Castile's case and Biden's had one thing in common -- the person at the center of the case was a drug user. Also the NRA rarely has much to say about law enforcement shootings, regardless of the ethnicity of the victim

OTOH, " the 2A crowd" (which is a lot larger than the NRA) did actually have quite a bit to say about Castile and about Hunter, yet were mostly ignored by the major media.
