Texas school district agrees to remove ‘Anne Frank’s Diary,’ ‘Maus’ and 670 other books after right-wing group’s complaint (forward.com)

Conservative activists, led by a local pastor and outspoken Israel advocate, pushed the district, Mission CISD, to excise books mostly about gender, sexuality and race. Their demands represented an extreme version of a nationwide culture war over books that has played out in recent years — and ensnared a number of books with...

I’m definitely not for banning books, but couldn’t you say the same thing about news media? Or Facebook memes? Those “get you to think”.

Depends who you are. If you’re a person of interest to the Russians for any reason, I wouldn’t trust it.

How does generative AI create convincing lighting in images?

I believe lighting plays a very important part in making a scene realistic when it comes to creating one artificially, like in 3D modelling. That is why I also think the lighting of these AI generated images is the prime source of what impresses people about these images since no matter how unrealistic or distorted the subject...

I’m an AI researcher and yes, that’s basically right. There is no special “lighting mechanism” portion of the network designed before training. Just, after seeing enough images with correct lighting (either for text to image transformer models or GANs), it will understand what correct lighting should look like. It’s all about the distribution of the training data. A simple example is this-person-does-not-exist.com. All of the training images are high resolution, close-up, well-lit headshots. If all the training data instead had unrealistic lighting, you would get unrealistic lighting out. If it’s something like 50/50, you’ll get every part of that spectrum between good lighting and bad lighting at the output.

That’s not to say that the overall training scheme of especially something like GPT-4 doesn’t include secondary training operations for more complex tasks. But lighting of images is a simple thing to get correct with enough training images.

As an aside, I said that website above is a simple example, but I remember less than 6 years ago when that came out and it was revolutionary, so it’s crazy how fast the space has moved forward in such a short time.

Edit: to answer the multiple subjects question: it probably has seen fewer images with multiple subjects and doesn’t have enough “knowledge” from it’s training data to accurately apply lighting in those scenarios. And you can imagine lighting is more complex in a scene with more subjects so it’s more difficult for the model to use a general solution it’s seen many times to fit the more complex problem.

Same. I’ve found I’m most productive from like 3-7 pm, which sucks. I’d like to be productive in the morning or in the early afternoon instead of mostly past regular work hours.

Hahaha, as someone that works in AI research, good luck to them. The first is a very hard problem that won’t just be prompt engineering with your OpenAI account (why not just use 3D blueprints for weapons that already exist?) and the second is certifiably stupid. There are plenty of ways to make bombs already that don’t involve training a model that’s an expert in chemistry. A bunch of amateur 8chan half-brains probably couldn’t follow a Medium article, let alone do ground breaking research.

But like you said, if they want to test the viability of those bombs, I say go for it! Make it in the garage!

How the Recycling Symbol Duped People into Buying More Plastic (www.scientificamerican.com)

Plastic wrap tangles around sorting equipment at recycling facilities, shutting down operations as employees try to cut it out of the equipment. Huge bales of paper shipped overseas can contain as much as 30 percent plastic waste. “Contamination is one of the biggest challenges facing the recycling industry,” the EPA said in...

Is this not deployed already? If it isn’t, what the heck are we doing?

I know cardboard and especially aluminum is much easier to recycle, so doesn’t just have to be plastic.

He’s my hero! I hope he’s still getting something out of life as he’s in Brazil with his wife. A true heartache knowing that his time here is coming to an end, because for as long as he could, he was still commenting on international affairs. A warrior for the truth, and I’m going to miss his commentary.

I agree with him. You have to take measures to protect the populace, like with traffic laws. If people can’t abide by those rules and the science is sound (which it is in this case and in the case of traffic laws), then measures have to be taken to protect the community from those that refuse to abide by the verifiably safer option without due cause.

What those measures are can be deliberated amongst the community. Could be fines, could be jail time. I don’t know what would compel someone to get a vaccine, but that could be determined over time.

Conservatives are just projectors. Everything they are guilty of they blame on political opponents or demonize: pedophilia, gay sexual relationships, corruption, and not caring about the average worker. That’s not to say Democrats don’t sometimes fall into these categories, but it’s definitely to a lesser extent.

Tough shit Zuck

Well, that’s the difference. At different points in my life I’ve had varying levels of self-control. You have a higher bar than I do right now for what requires a self-control check.

My username is what it is for a reason. I don’t think being on a site like this improves my health or mentality in any way, yet here I am. I still go on Reddit on a desktop when I’m working almost out of habit, even though I’m kicking myself mentally the whole time I’m scrolling. I wake up, say “30 more minutes” to myself knowing full well that will make me start work later, less prepared, hungry, and unshowered and I’ll have to work later into the night (when I work from home). I watch YouTube until 1 am or later most nights because I don’t want to sleep even though I’m tired and I know it will make my day miserable tomorrow. Dishes are piling up because I say I’ll get to it later.

People have different thresholds for this and at other times in my life I could just shut off many of these urges. Right now, because of my mental health, that ability for self control is near zero. Just think of that push-back you get when you say to yourself you’re going to go for a run and imagine that push-back to be stronger and applied to literally anything that requires effort or mental presence.

I responded to your other comment, but I like this question too. I haven’t been addicted to a substance, but I can firmly say for other things that the answer is “No”. I’m not blacked out, I’m completely present when I’m making this choice, but sometimes there’s a constant justification of “ok I’ll do it this last time and tomorrow is when I’ll resist it.” And you keep doing that. And that voice gets weaker over time to where you just start accepting that this is what you do now. And that often comes with self-loathing and frustration.
