[ "rapid volume changes cause artefacts in AVAudioPlayer", "I have some pure tones (sine waves) that I need to fade in and out and also adjust their volume arbitrarily through a thumbwheel. I generate the PCM data along with a WAV header and then encapsulate it in an AVAudioPlayer which plays back fine at constant volume.\n\nNow, as trivial as this sounds, I'm finding that changing volume rapidly on iOS 7 causes some pretty nasty artefacts. Imagine a tone playing with a slider controlling it's volume. Moving the slider around rapidly will cause the noise I'm describing. It's particularly obvious because the source signal is just a tone. If it were music, things would likely just get lost in the relative noise. Oddly, if I directly instrument the device volume via MPMusicPlayerController instead of trying to control things either through AVAudioPlayer's volume or even at the byte level, I get much smoother results and no artefacts. I suspect the device is doing something when it's volume is adjusted that I am not.I know this kind of quantization noise is an issue in audio processing and I'm wondering if anyone may have some advice.\n\nI've also reproduced the issue using sample level playback via Novocaine. No matter what I do, I can't seem to get smooth, noise-free fade in/out characteristics. Any help would be much appreciated." ]

This works if I'm Remote Desktop'ed into the remote machine running Rails and the game server, but as soon as I disconnect my Remote Desktop session, it doesn't work anymore.

However, my errors do not show up as green/red squiggles in the Visual Studio editor. This is supposed to be possible with Roslyn analyzers, according to Microsoft's documentation, but nothing is said of source generators specifically. Since source generators are treated like Roslyn analyzers, though, I imagine this should be possible. I've managed to replicate my issue with a small example, consisting of a source generator project and a test project on which to run the generator. As a test, the generator reports a diagnostic error whenever it sees a method that doesn't return void. I intend for red squiggles to appear under the offending method's name:\nSource generator:\n[Generator]\npublic class SampleGenerator : ISourceGenerator\n{\n public void Execute(GeneratorExecutionContext context)\n {\n DataReceiver r = (DataReceiver)context.SyntaxReceiver;\n foreach(MethodDeclarationSyntax method in r.Methods)\n {\n IMethodSymbol symbol = (IMethodSymbol)context.Compilation.GetSemanticModel(method.SyntaxTree).GetDeclaredSymbol(method);\n if(symbol.ReturnType.SpecialType != SpecialType.System_Void)\n {\n context.ReportDiagnostic(Diagnostic.Create(\n new DiagnosticDescriptor(\n "SG0001",\n "Non-void method return type",\n "Method {0} returns {1}.

[ "performing calculations and comparisons using indices in numpy arrays", "I have a 3D numpy array of voxels, i.e. where the indices of each point correspond to its position in 3D space.\n\nThere are a number of calculations I wish to perform that involve knowing whether the points satisfy various geometric conditions. This means converting the indices into vectors by multiplying by the basis, and then calculating dot and cross products, norms etc.. I am looking for a reasonably fast way to do this, as my efforts so far seem very slow.\n\nIf I have an arbitrary basis a, b, c:\n\nbasis = np.array([[a1, a2, a3],\n [b1, b2, b3],\n [c1, c2, c3]])\n\n\nwhere a1, a2, a3 are the x, y and z components of a, and likewise for b and c.\nI can calculate the Cartesian coordinate p = (x, y, z) of each voxel in the following way:\n\nfor i in range(vox.shape[0]):\n for j in range(vox.shape[1]):\n for k in range(vox.shape[2]):\n p = np.dot(basis, np.array([i, j, k]))\n\n\nwhere \"vox\" is the 3D array of voxels. If, for example, I wish to calculate the dot product of each of these vectors with a single other (Cartesian) vector (e.g. q = np.array([qx, qy, qz])) and store that index if the result meets a given condition (here greater than 0.0), I could do something like this (within the same loop as above):\n\n if np.dot(p, q) > 0.0:\n desired_vox_indices.append([i, j, k])\n\n\nThe problem is that this is very slow. Can I do this in a more pythonic way, or by using more numpy tools? I realise I am not even accessing the values of the vox array at this stage either.\n\nEDIT: attempt at cross product based on answer by Divakar\n\n# Get q_x (matrix multiplication version of cross product)\nq_x = np.array([[0.0, -q[2], q[1]],\n [q[2], 0.0, -q[0]],\n [-q[1], q[0], 0.0]])\n\n# transpose (as per cross product definition) and matrix multiply with basis\nu = np.matmul(q_x.T, basis)\n\n# Get open range arrays\nm,n,r = vox.shape\nI,J,K = np.ogrid[:m,:n,:r]\n\n# writing everything explicitly, since I am unsure how ogrid objects behave\npxq = np.empty(3)\npxq[0] = u[0,0]*I + u[0,1]*J + u[0,2]*K\npxq[1] = u[1,0]*I + u[1,1]*J + u[1,2]*K\npxq[2] = u[2,0]*I + u[2,1]*J + u[2,2]*K\n\n\nwhich might be the same as just:\n\npxq = np.dot(u, np.array([I, J, K]))\n\n\nbut I am not sure..." ]

Maybe something like this could be run on a continuous integration server just to verify that things match up?\n\nHrmm....and now a thought just occurred to me. Is it even possible to create a mock/stubbed method that doesn't exist? If not, then this whole question is moot.\n\nEDIT:\n\nI just tried this out using rspec 2 and I know I can create a Book instance and create a method named i_dont_exist and I can call it just fine.
