China has built and deployed nearly 1.25TW of renewable energy in five years, and they're deploying on an exponential. If you're trying to convince me this isn't impressive or relevant to our future "because they still g

This attack predates OpenAI and the German wiki attack (which OpenAI confirmed was theirs) and shares agent naming conventions. So seems unlikely that someone went back in time to frame OpenAI before the HF stuff was even known publicly.

Because right now the Department of Justice is shut down for causes that the administration supports, which includes OpenAI, and none of the victims want to sue over it.

There are two phases I've seen in becoming a security engineer. The first phase is moving beyond the "I am an engineer" mindset, where the goal is to build systems that fit into a specific set of design constraints. You have

Prompting a system to give a history of a person’s movements (even if they’re movements “in public”) is not something that has any historical analogy. The law has slapped down the “it’s in public” argument in cases like this, see eg Baltimo

The question is not "does OpenAI know", it's "can OpenAI attest that the usage of their products for confidential data is not going to cause that sensitive data to become known to their models". And right now the an

The long tail is what scares me. Chrome will get fixed. Major OSes will get fixed. But your enterprise software and all your appliances? Shit.

I'm still waiting for someone to build a fine-tuned local "Anarchist Cookbook" LLM. We haven't seen LLMs tuned for bad purposes yet, I have to imagine someone somewhere is thinking about it.

Re: complexity. I used to find AWS unusable, then I realized I can just tell Claude Code or Codex to manage it. This makes it into an entirely different product, where "Cloudflare is easier" doesn't really matter. Now price i

If I had the email address of every researcher in my field, I would never send a mass email to them describing my latest goofy idea. I would, however, send my latest goofy idea to a conference with those same reviewers (if I felt it was t

This sort of thing is really useful for helping people to understand what the purpose of scientific publication is. It's not about presenting finished products to society, it's more like a Discord where you communicate new finding

DraftKings alone is estimated to do $6.5bn in revenue in 2026, and the whole US segment is close to $20bn. This is the market that Kalshi et al. are targeting, and these are huge sums of money. You can make sports betting artificially look

Sports betting was, if not prohibited, then highly-proscribed for most of my life. You could do it in a few places like OTB, go to Vegas, or deal with an illegal bookie. People still gambled, but this made the problem orders of magnitude sm

The hope of SMR is that it can be cost-effective at the same level that other factory-produced power sources are. If that's not on the table, then large-scale nuclear deployment mostly isn't going to happen.

Maybe, but I think this misstates how security vulnerabilities work. Vulnerabilities are logic flaws, and we have every reason to believe that there is a maximum number of such flaws in any given system that allow exploitation; and even tha

Once you have a sustainable process, these last holdout areas like dredging (where you can't use batteries or wires) can have relatively terrible EROI as long as they're a small minority of the economy. All aviation and shipping c

Owner of a Model 3 here: I absolutely need to look at the screen to know what speed it's set to, or if I've accidentally turned it to "Off" or "Auto". The scroll wheel does not tell me this. It's very diff

This is already how Medicare works and it covers 70 million Americans. I’m not aware of any of these hypothetical violent outcomes being a huge problem for the program.

This particular brand of confrontational nuclear “advocacy” does not help nuclear. Please consider stopping it.

I was an introvert to the point where I started getting my hair cut at a place that plays movies, just to avoid awkward conversation with my hairdresser. Post-pandemic, I love talking to barbers and cab drivers, even if they have crazy idea

The Federal laws on grants are Byzantine and I’m not going to defend them. I think they make research much too expensive, and the compliance costs exclude smaller businesses and institutions. With that said: the general public voted for th

I’m genuinely not an expert, but isn’t the beauty of MoE models the fact that we explicitly don’t evaluate every parameter on inference? We evaluate exactly the subset that are needed to evaluate a prompt. Seems like this will bring back da

Some of this overhead is nonsense. A lot of it is training and fellowships. Some of it exists because the government has strong regulations to prevent self-dealing and fraud. I certainly think some of those regulations could be relaxed, but

What I think should happen is that these schools should increase their class sizes to match demand, rather than keeping them artificially low in order to game acceptance criteria. I think it’s a systematic societal failure that we’ve create

The Ivy League (and top-tier) situation is out of control, and genuinely raises questions about whether institutions like this should exist.

They started stockpiling in 2024. The estimate is that they had 1.4 billion barrels by the time the Iran war started, and they're down to 1.2 billion now. (Nobody knows for sure, though.) Meanwhile the US has 304 million barrels left i
