How would non-permanent credits even work? You purchase the carbon-offset option on a flight, a tree gets planted somewhere, ten years later it burns in a wildfire. Then what?

Sudden availability of capital and the perceived need to be seen doing something with it can be a curse. WeWork comes to mind, eg. Stay lean and mean until you actually need the capital. A company like DeepSeek will have zero issues raising

The endangered art form of human mathematics is one thing. Another thing is that there seems to be little concern for whether a theorem was created using a documented open-weights model or some unknown model in a web chat. If you want to ma

My favorite moment of this kind was when the teacher said 'Ok, and for the rest of the course we will look at a completely different problem', and the equation he wrote down was exactly the same as before. Except that the letters

UX is not the problem with Passkeys. Passkeys were designed to align with the interests of BigTech, who are bent on stopping the abomination that is general computing devices in the hands of consumers and forcing them into their walled gard

Well. Lots of math that boils down to 'predicting the future is hard'. Especially when the future is one of social construction, that's what gets lost a bit here. Predicting the future is easier for planetary motions than for

git as-is is completely unfit for purpose and a huge security risk for this use case, because it uses MD5, which is no longer collision-resistant. If your proposal is 'something like git, with a few modifications to make it suitable fo

Clearly, you would scope the features and choose implementation options so that it makes sense for the use case. Mining (ie PoW and/or Nakamoto consensus) is clearly inferior to any deterministic consensus here. A cryptocurrency isn&#x

by c7b 3mo ago
That is what I'm saying. And you may be right, but the security guarantees are math and math is patient. If people decide to ignore it today, it'll still be true any time they decide to take another look.

Agreed that you don't need total ordering and hence consensus for pure asset transfers. But if you want to make any changes at all, like updating the list of nodes, you do. So in practice, you do need it. Every other proposal will fall

You need that anyway. It's not technology that's stopping notaries from falsifying transactions in the current system.

You can put an index on your blockchain DB, what are you talking? Every node can manage it as it pleases (within the limits of the consensus algorithm). Yes, if you have a centralized model you don't need it. Just saying that this inci

Internally, you don't need it, agreed. But that is centralization risk exemplified in this incident. Which isn't necessary. Every notary could be a node. It would be a lot more resilient, and it would look a lot like a blockchain

A blockchain solves the problem of consensus under Byzantine faults. Payments are an incidental use case, and not even a good one because managing payments including avoiding double spending can be achieved with a weaker primitive than cons

by c7b 3mo ago
A blockchain isn't stopping you from doing any of those things, if anything it's facilitating different backup models by different parties. A paper record is so much more susceptible to various kinds of risks, adversarial and ot

Neural machines were always going to be an alternative computing paradigm to von Neumann machines. Had it not been for Minsky we would arguably have gotten to a point where they're useful sooner. But why do you say that as if it's

Agreed, the Strix Halo doesn't feel good enough for $4k. It was supposed to be $2k (and was so until 6-12 months ago), which felt like a great deal. Not the best AI chip but you get what you pay for. A tinkerer's dream that could

Bit of a tangent, but it's fun to think about how much it takes to become a -er, -ian or -ist in a given field. Philosophy is probably one of the hardest, you need to be seen as up there with the all-time greats. In history or physics

I think we're on the same team, I find the general attitude towards security in the current AI scene scary. I was just hoping for a bit more ammunition than what that article gave us.

Hmm the list is a bit underwhelming. Basically, it's unnecessary requests, bloated JS, unoptimized images and generally poorly structured code. I would hate if that was where the average website is headed, but realistically, we were al

Even more important in a local context is the difference between token generation and prompt processing speed. We tend to focus on the former, but for multi-turn/agentic workflows the latter can dominate.

You're the one making things up. An M3 Ultra with 128GB RAM doesn't exist, the M3 Max has 410GB/s bandwidth [0]. I was of course talking about the M4 Max with 546GB/s, which was closer to twice the price of a Strix Halo

The M4 Max with 128GB RAM has 546GB/s memory bandwidth [0], compared to Strix Halo's 250 (on the label, I've yet to see a benchmark that tops 220). It's not available at 128GB RAM anymore, at least in my shop, but when i

But ideally they would be competitive, right? If your goal is LLM or Diffusion inference or - god forbid - training, you're going to get way better performance on DGX Spark. The difference is more stark than 250 vs 273 GB/s bandwi

by c7b 3mo ago
This is just a little under the price of NVidia's DGX Spark with CUDA or a Mac with 128GB and twice the memory bandwidth. The point of Strix Halo used to be that it was half the price of those way more capable machines. You'd be c

I'm sure there will be a fix for it, but it illustrates an important broader point I should probably have made above: if you opt for local AI today, expect to run into some issues. Expect to learn a bit about the tools you're usin

I'm saying, either you have a problem with the copyright issues related to AI training or you don't. If you do, neither Qwen nor Claude are acceptable, if not then both are. They have similar moral standing to me. Btw, ethically s
