Unfortunately this is a quite general issue with Julia at the moment. If things work it's magical, if they don't it's hard to see what subtle assumption of the packages used was violated. Julia and C++ Templates share a lot o

git user interface design is a disaster. It's no wonder it's hard to document (this is a bit orthogonal to your point...). Git has an extremely complex data structure/state: It's a forest of DAGs (commits in distributed

This this this. Sooooo much. This always was flying spaghetti monster level unlikely. People simply do not understand how tightly constrained things like this are by existing evidence. And almost uniquely so. When experimentalists announced

This seems a lost battle. Every EM Drive discussion I have seen has been dominated by non-scientists pontificating about how we don't know anything, and our theories might be wrong, and we should keep an open mind ...

I agree that on this point the analogy is weak. But it describes the ignorance of all those hyping it up well. People are generally aware that if someone is presenting a perpetuum mobile they are wrong. Free energy doesn't exist. The f

Animats explained the meaning of rejected energy in the diagram below. It's efficiency losses in the entire system (I wasn't aware of this terminology). The actual size of load balancing energy used is quite small. I didn't k

The best I can guess is that the author is mixing up load balancing through reserve energy and efficiency losses. The amount that is reserved for load balancing is also not anywhere near the size they are talking about.

The author is absolutely wrong on power grids. The power grid is over-provisioned in the sense that it has a lot of power on stand by. The physical electrical grid is really balanced more or less instantaneously. Inertia in generators toget

Unfortunately I am to late to edit my post. I understand the intent here, but these threads are full of what are, in the end, drastic accusations of scientific misconduct (or raging incompetence) against the authors, made with confidence fr

You clearly haven't actually looked at how the damages are modelled have you? You just in your head inveneted a naive way in which to estimate damages and then argued that that doesn't work. There is a large and robust literature

One thing is the Core Team Members and their long term plans, which I'm not privy to. The other is the impression generated by interacting with others in the community online, where people disagree with the very premise that there is a

My impression with this is that it's mostly coming from a few academics that never work on code they haven't written themselves, and that have no understanding of use-cases other than their own...

I feel your pain on interfaces. As it stands, Julia simply doesn't encourage carefully thinking/documenting about what assumptions your code makes and just banging things together, hoping they work. Good luck dealing with any obsc

I don't think that's fair, simply because things have actually gotten a lot better. This is shown in this blog post and it also is evident to people who use Julia: https://i.redd.it/ik4uymvb28k51.png Also, compili

Mathematically speaking, even though there is a recurring cost, if the cost goes down over time it's entirely possible for the cost to be finite overall. Simple example: If the recurring cost halves every year, and in the first year it

Also, to put the double standard here into context, HN comment threads always had plenty of people defending Linus Torvalds tone.

Just to give you a feel of what is actually possible in a well run election: Germany (80 Million people) has a fully manual (all paper ballots, no voting machines or automatic tallying) and fully witnessed official result on election night.

No we don't. The law is against insulting people, not against "saying stuff we don't like on the internet". The laws predate the internet by decades. The freedom to express your opinion is constitutionally protected, thi

This is a typical slight of hand in these discussions. We are talking about deeply intolerant, bad faith actors, and you substitute this with "censoring opinions outside the mainstream". This is deeply dishonest by you. We are not

That's great to hear! I am sure there is a lot of room for improvement and that would go a long way! But it also seems to me that with the language as it is now, the compiler simply doesn't have enough information to provide good

I can second this. I once implemented my own sparse matrix multiplication because I needed it in numba. Further, the type of automatic differentiation that is possible now is game changing. On the other hand Julia is a terribly designed lan

Agreed. As far as my household is concerned there are two relevant VR experiences: BeatSaber and Alyx. (Serious Sam of all games gets an honourable mention). We would not own a Quest if not for Alyx.
