If you dig a little you can get the articles explaining better, but basically: yes, you have to have the weights, and a secret key... Given those, they split the words that might be chosen at each point into two groups and only choose from one group.

Later, you can check for the watermark by splitting the same way and seeing how many times the words in the text match the group that fits with the secret key. Normal text would hit a 50% match, but unlatered AI generated text would hit 100% match, so... somewhere higher than 50 you start to suspect AI involvement, possibly edited, and by the time you get over 99% it's virtually certain that AI had some involvement - particularly if the sampling of words runs into the thousands.

Don't confuse me with facts! (And, thanks... I have since seen the articles about how it works based on word selection from a subset of the words that would have been randomly selected by the "heat" of the model.)

Does it do parametric model designs?

Yeah, I "vibe coded" a timesheet app in about $15 of Claude subscription credits. Actually did it twice: $10 for the Python version, then migrated that to Go for $5 - it does run a lot faster in Go while simultaneously consuming less power / resources. It makes a couple of nicely formatted timesheets, serves multiple clients with multiple service providers, tracks everybodys' shifts, providers can log in from their phone and accept/drop shifts, schedulers can create new open shifts for providers to consider, etc. etc. - been using it for about a month now, so far the math is flawless - as compared to the human+calculator math that was being used before which seemed to have at least 1 error per 10 shifts computed.

Everybody should have been looking at the quality of their output before LLM tools were even a thing. They never should have stopped, if they did, that's on them just like Tesla drivers napping at 80mph.

That's really about the time and effort you put into the construction of the model and what you're trying to model in the first place.

For the most part, the LLMs are really bad at building say - a cat with realistic long fur. However, they can be good coloborative tools teaching you how to use Blender to build a decent cat with realistic long fur for yourself - speeding up that learning curve quite a bit over reading "Blender for Dummies" examples and building from there...

It's like comparing a stone sculptor to a welder where the welding tools started as magnifying glasses in the direct sun a year ago worked up through acetylene torches and now you've got 400A precision TIG arc welders to screw up with...

I'm going to guess if you expressed what you want to a decent LLM, it could generate it for you to copy-paste.

[–] MangoCats@feddit.it 1 points 3 days ago

Seriously, I have been screwing around with AI for coding for 12 months now. The prompts I had to give 12 months ago to make the LLM generate decent code are mostly un-necessary now, the models have learned to do those things for themselves, so I am now prompting for the less-obvious stuff. Whatever they're missing, that's what you need to be prompting.

How about: AI Generated 3D models flood the free / open source repositories, anything wrong with that?

Sounds to me like the people who designed Luna should have had Luna scaffold the appropriate deterministic tools instead of smushing all the policy decision making into 200K tokens of working space (roughly the brain capacity of six bumblebees.)

Management has been overrelying on "data dashboards" to justify their hire/fire decisions for decades. This "dashboard" just happens to be capable of producing an articulate paragraph stating why the decision matches established patterns.

 

What is this recurring connection between big missiles sending men to the moon and the military industrial complex sending expeditionary forces overseas?

 

996: 9 a.m. to 9 p.m., 6 days a week

Sure, they're burnt out, sluggish, surly, but... they're present. And when they're present, they're not out in the world spending their income. They don't need an expensive apartment or house, all they do there is sleep. Why have a fancy car when all you do is drive to/from your shitty job in it? Family? Who would have children with somebody who works such a schedule?

Even if you got more productivity from the same workers on a 9 a.m. to 3 p.m., 4 days a week schedule, you'd have to pay them more, not just per hour but overall, because they'd be out spending money on those afternoons / evenings and 3 days a week they have off. Organizing, demanding better healthcare, dental, more paid time off for vacations, and higher total wages to support all these "needs" they invent for themselves on their time off.

Keep 'em locked down, keep 'em tasked with ... anything, doesn't matter if it's productive or not, as long as it keeps them on-the-job and not spending their pay.

Edit: apparently this isn't clear: 996 is a horrible idea from all perspectives, it's bad for the workers and bad for their employers overall. But, in certain twisted views, it would be a bit like military service where the (bulk of the) workers get a pitifully small paycheck, but they don't have any real expenses so they have the option to save it all. 996 would turn that more into a wage-slave implementation where the pitifully small paycheck is just enough to meet their pitifully small expenses. In the China tech sector where they have implemented this (it is now illegal, but still practiced) they also do things like install anti-suicide nets in the stairwells of the highrises the workers work and sleep in.

A prominent computer scientist who has spent 20 years publishing academic papers on cryptography, privacy, and cybersecurity has gone incommunicado, had his professor profile, email account, and phone number removed by his employer Indiana University, and had his homes raided by the FBI. No one knows why.

Xiaofeng Wang has a long list of prestigious titles. He was the associate dean for research at Indiana University's Luddy School of Informatics, Computing and Engineering, a fellow at the Institute of Electrical and Electronics Engineers and the American Association for the Advancement of Science, and a tenured professor at Indiana University at Bloomington. According to his employer, he has served as principal investigator on research projects totaling nearly $23 million over his 21 years there.

He has also co-authored scores of academic papers on a diverse range of research fields, including cryptography, systems security, and data privacy, including the protection of human genomic data. I have personally spoken to him on three occasions for articles herehere, and here.

"None of this is in any way normal"

In recent weeks, Wang's email account, phone number, and profile page at the Luddy School were quietly erased by his employer. Over the same time, Indiana University also removed a profile for his wife, Nianli Ma, who was listed as a Lead Systems Analyst and Programmer at the university's Library Technologies division.

According to the Herald-Times in Bloomington, a small fleet of unmarked cars driven by government agents descended on the Bloomington home of Wang and Ma on Friday. They spent most of the day going in and out of the house and occasionally transferred boxes from their vehicles. TV station WTHR, meanwhile, reported that a second home owned by Wang and Ma and located in Carmel, Indiana, was also searched. The station said that both a resident and an attorney for the resident were on scene during at least part of the search.

Attempts to locate Wang and Ma have so far been unsuccessful. An Indiana University spokesman didn't answer emailed questions asking if the couple was still employed by the university and why their profile pages, email addresses and phone numbers had been removed. The spokesman provided the contact information for a spokeswoman at the FBI's field office in Indianapolis. In an email, the spokeswoman wrote: "The FBI conducted court authorized law enforcement activity at homes in Bloomington and Carmel Friday. We have no further comment at this time."

Searches of federal court dockets turned up no documents related to Wang, Ma, or any searches of their residences. The FBI spokeswoman didn't answer questions seeking which US district court issued the warrant and when, and whether either Wang or Ma is being detained by authorities. Justice Department representatives didn't return an email seeking the same information. An email sent to a personal email address belonging to Wang went unanswered at the time this post went live. Their resident status (e.g. US citizens or green card holders) is currently unknown.

Fellow researchers took to social media over the weekend to register their concern over the series of events.

"None of this is in any way normal," Matthew Green, a professor specializing in cryptography at Johns Hopkins University, wrote on Mastodon. He continued: "Has anyone been in contact? I hear he’s been missing for two weeks and his students can’t reach him. How does this not get noticed for two weeks???"

In the same thread, Matt Blaze, a McDevitt Professor of Computer Science and Law at Georgetown University said: "It's hard to imagine what reason there could be for the university to scrub its website as if he never worked there. And while there's a process for removing tenured faculty, it takes more than an afternoon to do it."

Local news outlets reported the agents spent several hours moving boxes in an out of the residences. WTHR provided the following details about the raid on the Carmel home:

Neighbors say the agents announced "FBI, come out!" over a megaphone.

A woman came out of the house holding a phone. A video from a neighbor shows an agent taking that phone from her. She was then questioned in the driveway before agents began searching the home, collecting evidence and taking photos.

A car was pulled out of the garage slightly to allow investigators to access the attic.

The woman left the house before 13News arrived. She returned just after noon accompanied by a lawyer. The group of ten or so investigators left a few minutes later.

The FBI would not say what they were looking for or who is under investigation. A bureau spokesperson issued a statement: “I can confirm we conducted court-authorized activity at the address in Carmel today. We have no further comment at this time.”

Investigators were at the house for about four hours before leaving with several boxes of evidence. 13News rang the doorbell when the agents were gone. A lawyer representing the family who answered the door told us they're not sure yet what the investigation is about.

This post will be updated if new details become available. Anyone with first-hand knowledge of events involving Wang, Ma, or the investigation into either is encouraged to contact me, preferably over Signal at DanArs.82. The email address is: dan.goodin@arstechnica.com.
