The problem is when the chat bot, which basically plays along with whatever you say and creates a feedback loop that reinforces your beliefs, starts picking up on hints you might harm yourself and starts encouraging you to do it.

The problem is when amplifies, rater than alleviates, delusions and psychopathy.

AI is not intelligent.

Feels like the people defending/advocating it are failing to understand it. The rest of us just look at what's already actually happening and realize that it should probably be regulated if not stopped completely.

Comment Not sure it is a serious problem (Score 2) 42

I'm in math and there's been a noticeable growth in this sort of thing, either very low quality papers or papers which are just wrong. But almost universally these are in terrible journals that one isn't going to spend any time looking at. Within any given field, recognizing which journals are of reasonable quality should not be that tough. On the other hand, for at least some fields which have just massive numbers of journals, it may require more work. But by and large most of these papers and entire journals are just going to get ignored by the people doing serious research.

Comment Re:Outdated and anti-competitive isn't the relevan (Score 1) 61

I'm struggling to see how there's a violation of the anti-trust laws. Admittedly, I'm not an expert, but states are allowed pretty large leeway in how they regular businesses, and the Sherman Anti-Trust Act https://en.wikipedia.org/wiki/Sherman_Antitrust_Act doesn't really interact with states doing something like this in any obvious way.

Comment Outdated and anti-competitive isn't the relevant (Score 3, Informative) 61

A law can be "outdated and anti-competitive"- but a court is not in general going to strike it down for that. They do claim that the law is irrational which does matter more; courts can and have struck down laws as having no rational basis. But that's an extremely tough burden, and the state just has to come up with some reasonably plausible rational reasons for the law. Reasons used to justify such laws include that they helped alleviate an imbalance in power between car manufacturers, dealers and customers, and that they made sure that there was an easy and natural way for warranties to handle cars. They were also seen as a way to promote local business. Now, in the modern age, all of those seem like pretty poor reasons that don't remotely justify the negatives. But that's exactly the sort of balancing that is the job of the legislator to decide, not the courts.

There's a lot of info available about attack mitigation (or just hungry crawlers) and how to avoid/blackhole them. Problem is, you have to have control of portions of the network stack to do them effectively.

Security through obscurity only works so long as you can be obscure, which is part of the vibe of the post. It's really stressful sometimes, depending on what's hosted.

Of the sites I don't have behind Cloudflare, the assets aren't worth anything and I truly don't care if they show up in AI. Otherwise, what's mine is mine, and not theirs.

If you can afford it, also consider Cloudflare; their bot identification is really good. You can use defaults or make your own filters. They're not the only ones that do this, but my experience with them has been positive. Much depends on your skills in how the web actually works, network + site interaction.

Their protections are cheap for the quality/speed. All of the large sites I manage are behind Cloudflare, including their DNS. Their DNS management is superior, and has interesting tricks for mixed-media sites. I don't work for either of these companies.

Get Wordfence if your site is Wordpress. The controls inside (free version) are enough to rate-limit crawlers effectively.

If you don't have Wordpress, your choices are more complex; you MUST use an IP filtering system and front-end your site with it to rate-limit everyone methodically. Crawlers eventually quite.

Many crawlers identify themselves in the get/post sequence. You have to parse those. If you understand fail2ban conceptually, it's the method used to create like-type gets that score with higher rates, and folder transversals. Accumulate your list and band them/null-route/block or whatever your framework permits.

Yes, you can blackhole through various famous time-wasters, but this also dogs your site performance. Captcha and others are becoming easier to fool, and for this reason, they're not a good strategy.

Once you decide on a filtering strategy, monitor it. Then share your IP ban list with others. Ban the entire CIDR block, because crawlers will attack using randomized IPs within their block. If you get actual customers/viewers, monitor your complaint box and put them on your exemption list.

There is a difference between "secret" and "Don't Crawl Our Site".

It's almost impossible to masquerade as a human; even throttled crawlers are easily identifiable through many different and often evil traits used.

The kleptocracy of AI (and other) crawlers is what's at issue.

Comment Re: stability of N6 (Score 2) 67

TNT pretty stable. C-4 burns hot but doesn't go boom when set on fire. Ideally explosives are stable except under the exact right circumstances. In fact, one of the major difficulties is balancing these issues. There are a lot of chemicals which are more explosive than the explosives we use but are too unstable to be used in weapons. As for the molecular formula, it is 6 nitrogens in a ring which is depicted in the last article. It is also the form you should guess since nitrogen normally forms two bonds.

Comment Re:Really cool, application to rockets not so much (Score 3, Interesting) 67

Yeah, but that by itself doesn't tell as that much. A lot of high temp superconductors were first synthesized in very tiny quantities and people later figured out how to synthesize them more efficiently, to the point where a lot them now can even be made in a decent quantity in a high school chem lab. And if this does turn out to be useful as an explosive (which requires it to not just be able to make a big boom but also to not want to go boom too easily) then my naive guess is that a fair bit of research into efficient synthesis will happen. It probably is going to turn out to be too unstable for military use though.

Sigh. You brought up SpaceX in a thread about the Australian company and said:

"declared the mission a success for igniting all engines and leaving the launch pad" yup bar is low when Musk rocket scorches off engines, showers debris on civilian cars and real estate and wildlife reserves, goes to 24 miles and explodes.

The point that you appear whether or not Musk or SpaceX existed, it is highly reasonable to for a first rocket launch attempt to be considered pretty successful if all engines ignite and you get off the pad. That was true before Musk and SpaceX even existed, and is still the case independent of whatever SpaceX is doing.

Comment Really cool, application to rockets not so much (Score 5, Informative) 67

People have been trying to synthesize N6 for about a hundred years. In that regard it is similar to trying to synthesize tetrahedrane https://en.wikipedia.org/wiki/Tetrahedrane. But people also synthesized cubane a while ago https://en.wikipedia.org/wiki/Cubane and attempts to make it large enough quantities for rockets were not successful. In the 1960s through the 1980s there was a general tendency to want to have really extreme substances and use them either as rocket fuels or rocket oxidizers. FOOF https://en.wikipedia.org/wiki/Dioxygen_difluoride and ClF3 https://en.wikipedia.org/wiki/Chlorine_trifluoride are the two most infamous ones, and both of those are really easy to synthesize, but just insanely dangerous.

However, one of the major insights in rocket development in the last 25 years has been that even if you can get a few percentage points more of energy out of a rocket fuel, if the fuel or oxidizer is really hard to make or really hard to safely use, then the difficulties involved just aren't worth it. Thus, the cheaper, more reusable rockets were now seeing like SpaceX's Falcon 9 and Rocket Lab's Electron use fuels like kerosene and methane. N6 seems like it would not fit in this paradigm unless someone comes up with a really efficient synthesis method.

That's all the more the case because twice as energetic as TNT isn't that energetic. Methane has a specific energy about 10 times that as TNT. TNT is really good as an explosive not as much because of its high energy but because it easily releases it all at once. So if N6 does get a use, it might be for making missiles and bombs.

Programming

The Toughest Programming Question for High School Students on This Year's CS Exam: Arrays 63

America's nonprofit College Board lets high school students take college-level classes — including a computer programming course that culminates with a 90-minute test. But students did better on questions about If-Then statements than they did on questions about arrays, according to the head of the program. Long-time Slashdot reader theodp explains: Students exhibited "strong performance on primitive types, Boolean expressions, and If statements; 44% of students earned 7-8 of these 8 points," says program head Trevor Packard. But students were challenged by "questions on Arrays, ArrayLists, and 2D Arrays; 17% of students earned 11-12 of these 12 points."

"The most challenging AP Computer Science A free-response question was #4, the 2D array number puzzle; 19% of students earned 8-9 of the 9 points possible."

You can see that question here. ("You will write the constructor and one method of the SumOrSameGame class... Array elements are initialized with random integers between 1 and 9, inclusive, each with an equal chance of being assigned to each element of puzzle...") Although to be fair, it was the last question on the test — appearing on page 16 — so maybe some students just didn't get to it.

theodp shares a sample Java solution and one in Excel VBA solution (which includes a visual presentation).

There's tests in 38 subjects — but CS and Statistics are the subjects where the highest number of students earned the test's lowest-possible score (1 out of 5). That end of the graph also includes notoriously difficult subjects like Latin, Japanese Language, and Physics.

There's also a table showing scores for the last 23 years, with fewer than 67% of students achieving a passing grade (3+) for the first 11 years. But in 2013 and 2017, more than 67% of students achieved that passsing grade, and the percentage has stayed above that line ever since (except for 2021), vascillating between 67% and 70.4%.

2018: 67.8%
2019: 69.6%
2020: 70.4%
2021: 65.1%
2022: 67.6%
2023: 68.0%
2024: 67.2%
2025: 67.0%

Marvel should get the rights. Maybe a Disney movie about WaspMan, to compete with the aging and tired Spiderman franchise.

While no one was looking, apparently, there was other news, like CPB going dark and Tesla being fined nearly a quarter billion dollars in liability due to premature auto-driving feature use.

But no, wasps. Radioactive wasps.
