Yea solving hard problems can be quite enjoyable, but can easily become a burden on your mind/body over time. When you're clearly making progress, then everything feels wonderful even if it's challenging. But when you're stuck, when your code/model isn't working as designed, if there is a clear gap between your current state of understanding and the amount required to solve the problem effectively, then you can fall quickly into despair. It's made worse when you see others doing similar work to what you do, but being far more successful at it. And made even worse, when you tie parts of your identity to the problem you're trying to solve, and the code you write. But that's the nature of what you're trying to do, so it isn't all bad.
Glad to see the release, Box2D has some of the best code I've ever read.
It's interesting to see that Box3D was originally a fork of a physics engine made by Dirk. Dirk is one of the best presenters in GDC, and so influential in Physics Engine space, nice to see how he's continuing to push the latest and greatest forward.
Can't speak to his technical skill, but going through this post, and several of his other posts, this man doesn't seem all that bright.
His takes lack nuance, there's no analysis in his writing, just what appears to be fuming at vague issues he sees in society.
This post is confusing to me. From the blog's name, in addition to these other blog posts [1] and [2], you would think he's contributing to the doomerism that he's lamenting here. If the singularity is near, and the big companies control capital, then the doomerism is correct, no?
To add to that, his lack of critical thought shows up in other posts as well [3]. He does not really understand the nuance of fiat currency or entitlement programs. Like the blog post above, he also seems to like "offending" people for the sake of offending them. In [3], he seems to think insulting Christianity, despite being a Christian himself but not believing in the core of the religion, is somehow getting back at "wokists."
I'm a visible minority who went from the GTA to Boston, everything is fine. People with this attitude are mostly fear mongering. No one I know has been harassed by ICE. Not saying they aren't doing terrible stuff, but the average tech worker is just fine in the US.
Would be similar to the typical simulations of humanoids. If you need to model the deformations of the human body, or get a proper model of tendons that make up humans, it'll be more difficult, but possible.
Proper simulators for those exist, you essentially need an engine with a compliant contact model. MuJoCo is the goto here, see:
No? This is only true if you assume that Newton’s only notable achievement was the creation of calculus. Newton did far more for physics and classical mechanics than Leibniz. Did Leibniz also discover the universal law of gravitation? Did he match Newton’s prism experiments in some way? In what sense can Newton be replaced by Leibniz?
I'm not in academia, so I might be fully ignorant about how things operate, but if professors don't reaed the actual paper, can do they know if it's BS or not?
Curious, when you do this, do you understand the math/reasoning of the paper and just have claude as do the coding? Not saying that matters if you just care about the end result, but I'm curious how much using an agent affects your understanding of what the papers are proving.
Awesome work, what always prevents me from implementing more solvers is the amount of math required. While the implementation always seems simple, understanding the different optimization strategies for each solver gets confusing.
It's really impressive that the author was able to implement rendering papers and physics sim papers with such regularity. It really is a feat. Makes me curious to see what their background is.
Can you elaborate on what you mean? It could be a matter of perspective, For a stack of blocks, each 1 meters high, the stack can get quite high and your expectations on how it should look like IRL might not be correct, due to never experience a large tower of blocks being knocked over at that vantage point. Especially if the mass of the objects are strange (super light for their size or super heavy).
I know in older games, the recommendation was to keep gravity low (~6 m/s^2 iirc) to help with simulation stability and make things look better, that might contribute to your idea of things being floaty.
I don't find the examples in the git repo to be especially floaty, but I work with a lot of simulators so I might just be used to it.
I was curious to see what someone elses perspective was on something I routinely engage with. I wasn't sure if it was someone trolling or genuinely upset.
Both those statements need to be prove for her, and I don't see any strong evidence for either.
And if someone was going to to make false allegations of abuse, why include specifics about how interrupting his calculus and drums caused his anger? Why not just say he was abusive, or state a more common reason for abuse? To me, the specifics make her statement more credible. Combined with his predatory history regarding women[1], I view Feynman as a distrubed individual (but a genius nonetheless)
I find the allegation credible, as I don't see why someone in her position would lie, and especially give specific details on what sets Feynman off.
Also, unless I see some concrete data about the amount/percentage of women who lie in order to get a divorce, the comment you linked is pure conjecture. Nothing really to argue about since it's just the vague idea of what people think about that time.
I don't think people really make up domestic abuse charges with this much detail. His wife explains in the post specifically what causes him to get so angry that he hurts her.
I don't see her having much incentive to lie and make up these statements, and see no evidence that she did lie. Some women lie about domestic abuse, most don't.
I don't agree with the parent commenters characterization of Karpathy, but these projects are just simple toy projects. They're educational material, not production level software.
- Depending on who you ask, you could also point to large-scale violations of the rights of migrants and asylum seekers, as well as the over-policing of minority populations.
The US also does not consistently uphold the same values that you say liberal democracies should. It does business with Israel, Saudi Arabia, and others.
As for your second point:
“It’s extremely relevant. If you believe in personal liberties and democracy, you should only do business with societies that uphold personal liberties and democracy. It’s that simple.”
I would ask, why? I believe in personal liberties and democracy for my people, my community, and my country. If another country’s population does not hold those beliefs as a majority, why is that my concern? If we truly restricted trade only to countries that share our beliefs, our list of trading partners would be very small. What would the benefit be?
Additionally, given your request for citations, I suspect we would disagree significantly on which countries actually reflect our values. I am not sure we could arrive at a consistent list of partners that share our values. For example, I do not believe the USA has a strong democracy. It has a rather weak one. Should it be excluded as well?
