You realize cygwin's setup.exe package manager has a CLI, right? The issue with pacman in msys2 is that it's posix dependent, which fails badly at updating the core posix layer itself. Cygwin's setup.exe is a native Windows e

Way too ascii-centric. Getting case transformations right in the presence of unicode can be complicated.

Is there any documentation or discussion on the justification for doing this? I'm scratching my head and asking why anyone would do this intentionally...

Equality constraints means you're working in a lower-dimensional subspace, I'd have to find out more about your algorithms but I'd be surprised if you wound up evaluating many feasible points at all (esp. with nonlinear equal

Without easy access to SIMD or value types (and JNI does not count as easy), the JVM's performance for regular computations on large datasets is still pretty lacking. Quoting http://cr.openjdk.java.net/~jrose/value

Oh, bummer, I even thought the Windows SDK still had the command-line compilers. What's it good for then? Most open-source projects don't even bother supporting MSVC, and I don't blame them one bit. MinGW-w64 gives a signific

What benefit does that really have over just using Clang with LLVM codegen though?
142.
by tavert 11y ago
That's unlikely to change any time soon, at least from the LLVM side. They're not really in the business of providing OS API headers. At least there's a Windows SDK download now that is smaller than the whole Visual Studio ID

It's much easier and lower-overhead to call into C, Fortran, and soon even C++, from Julia than it is from Python. If there's a library in Python but not yet in Julia, it's really easy to call into Python from Julia. What you

PyPy's adoption problem is not that it isn't the reference implementation. It's that it is incompatible with a huge body of Python modules that rely on C extensions. If you're going to lose access to libraries, may as we

Numpy is great for dense multidimensional arrays of (edit: fixed precision) floating point numbers. Most problems I face need to deal with richer, more complicated, less uniform data structures than that. Similarly Cython is way better than
