No, I'm saying even in that case you know it was intended to be a copy. If you wanted that to be a reference then you'd either (a) just do the obvious thing which is to just use the original variable name instead of creating a new

+1 for auto being overused. I always felt I was shouting into the void (hah) by saying the same thing... it's nice to see someone else agrees.

You're asking for the impossible. What you want is precisely what templates are, but you also want them to not be "templates" for... some bizarre reason. > I can have an array of T, but I can't specify that T is Numer

You probably did intend it to be a copy if you're binding it to a variable and need it to be non-const (like in the example)!

I thought the complaint was about the logic duplication, not the extra keystrokes. If you want type inference you already have auto. If you want to minimize your keystrokes, you're using the wrong language to begin with, whether there&

Okay yeah, Cheeger's inequality and all those are straight up graduate-level theoretical computer science. Definitely not something you can just throw into a discussion assuming people know what you're talking about!

What is the relationship? I guess most of us are not spectral graph theory experts. Are you looking at the adjacency matrix or the Laplacian matrix?

That seems reasonable, though likely less effective for some countries. It seems like an interesting regulatory idea though - maybe some regulator should maintain a list of trademarks whose advertising should be restricted? Not sure if that

Hm so what would happen if Facebook tries to buy Messenger ads for "Signal" in that scenario? Sorry I'm still not following.
45.
by mehrdadn 6y ago
I'm confused, what is the relevance of that to this problem? Wherever the results are coming from, ads will have to appear before them pretty much by definition, right?
46.
by mehrdadn 6y ago
It seems difficult to do this in general when so many search terms can have multiple meanings. Are you suggesting there should be human review for every ad? (Which is not saying it's necessarily a bad idea; just trying to understand ho

by mehrdadn 6y ago
I haven't, though I did download it. I was trying to work on an algorithm rather than solve specific problem instances, so I ended up just working around it by using different problem instances that didn't result in these errors.

by mehrdadn 6y ago
You're missing my point entirely. They don't need to solve this by keeping the variable real at every step or anything like that. What they need to do is to ensure the final solutions are real. Which means they need to solve it

I know how numerical stuff works, but no, this is pretty inexcusable. See my other comment: https://news.ycombinator.com/item?id=25689916

Not at all. I've worked on numerical stuff myself; unlike the symbolic bugs, I have little sympathy for these particular numerical errors. It would be far more reasonable if it was convoluted composition of functions, or some kind of b

Yeah. For what it's worth (not sure if it makes you feel better or worse...) I've found similarly bad bugs in SciPy too.

The trouble with SymPy is it's, well, buggy. I tried it a few years ago, and as soon as I got serious, I quite quickly ran into problems that I reported, some of which I now see they apparently still haven't gotten around to addre
