I agree, that should work. Thanks.

I must be missing something because I don't see how this is an advance over anything. You have a FREE function, so use-after-free at runtime is still possible. Why not just have malloc and free together then, and program in C but witho

What's the difference between PUSH and CONS? Also, what does the free-list register do?

These articles keep showing up here. This debate has been rehashed over and over again. These articles are never particularly well-argued or interesting. I've flagged it.

This might not even be news to the people in the knows. @foldfinance says We have known this to be the case with F2Pool for awhile but flashbots refuses to do anything See https://nitter.42l.fr/foldfinance/status&#x2F

Provide details. I don't know what "excessive" means here. They're going to be at least a bit conservative because they apply to more situations, but that's obvious.

I don't know how serious these things are, but if the San Andreas fault can tens of thousands of people (I doubt it, but I haven't looked into it), then indeed this becomes the priority. Economic policy should indeed focus on tryi

When it comes to computing motions, and interpolating between motions, this might be a nice way of doing it: https://www.youtube.com/watch?v=pq9YfdPHhIo I think that some computational geometry problems admit nice solutions

The point is that the magnitude of the outcome needs to be considered. Forecasting is about finding high probability outcomes, while not considering high-magnitude but unlikely outcomes. This makes forecasting sometimes a questionable activ

But isn't most of the developed world experiencing a recession? The US is energy independent, not having a Brexit, and still experiencing high inflation.

Can you really forecast inflation? They failed to do so before the whole Russia shit-storm, and they're trying to yet again. It seems to make more sense to base economic policy on finding choke points and vulnerabilities, and addressin

I'm more familiar with using differentiation in optimisation, where autodiff seems like the best method. I'm also aware of the fact that the differentiation operator is discontinuous, which makes me sceptical of finite-differencin

You define a dual number type in your programming language of choice, and overload the operators +, -, *, /, <, >, sin, cos, etc. Then you take a function which computes a numerical function f which is defined using the previous
