    Ooops, I didn't mean Xeon PHI, I meant an older design with many small x86 cores. Xeon PHI on the other hand was the first host of AVX-512 instruction set. Sorry.

    The programming model is not very flexible at the lowest level: one has to create all the software infrastructure to communicate with the GPU (which boils down to sending commands …

    The point I was trying to make is that if you have to rely on runtime type information, you might as well use sum types in a more strongly typed language, where the scope of the co…

    I think another interesting question is, how would you handle the return value of such function in your code? You would have to either: - test for the type of that value in order t…

    Disclaimer: I am not a HW designer, I could very well be wrong. It is true that there are tasks where threading matters, but still require a CPU rather than a GPU. I wonder however…

    > 100MB of doubles encoded as JSON. That sounds like a very bad use case for JSON. I would be surprised if your program wasn't more efficient with an ad-hoc binary format for that …

    Sadly, AFAIK, BLAS hasn't been updated to use generics. It would be so nice to have support for integer vector/matrix operations in there (not that it would require generics to hav…

    If you have a look at the different fortran implementations of BLAS gemm (matrix multiplication), you'll see that the transposed matrix cases are treated specifically. In fact, IIR…

    Oh, I understand. I suppose it makes sense, if for instance one needs to store a bunch of parameters somewhere, it might as well be a JSON file.

    The difference is that your DB is the FS, and each JSON file is an individual record. You're not storing each table in a single JSON document.

    Comment #23716444

    Maybe because it was tempting: JSON is fairly easy to handle, very portable, and when you look at a JSON document, it's straightforward to think about querying it, and thus DB, alt…

    Comment #23716357

    I think that, oddly enough, the point of that project is to use the JSON format as the DB storage format, not as an export option. Just from the look of it (I don't know either pro…

    Comment #23716308

    That's a very strange idea: JSON is basically structured data, like XML, it's nice for documents with deeply nested structures. The main issue is that contrarily to a DB, any modif…

    I wonder how the clipboard API could be fixed. I suppose that the current scheme is that apps are monitoring paste events, and when it happens have a look at the clipboard for copi…

    Comment #23626781

    Well, if copies may be borrowed, as it is the case in Rust, I suppose that a type-linear function, as I called it, doesn't have to be computationally linear. The `mult` example we …

    I don't think these technologies are related: Java Generics is based on subtyping, however Haskell doesn't support subtyping (afaik).

    Seriously though, the Opera web browser has this functionality built in, but it's a "toggle" back to top, by just clicking on the tab title. It's very useful on web sites like HN, …

    Sorry, I got confused on the meaning linear. As explained in the other answer, it's possible to implement the power function which is "type-linear" on each argument, but that funct…

    What's the provided GPU solution for ARM based machines? Do Apple SoCs contain a GPU?
