Discrete: AudioGenerator[{"Color", AudioGenerator[TimeSeries[{1}, {1}]]}] Continuous: AudioGenerator[{"Color", AudioGenerator[{"Sawtooth", .4, 5}]}] Joseph Stocke 2026-02-06T21:20:51Z https://community.wolfram.com/groups/-/m/t/3562641 **The problem** I run Mathematica 12 from home via a Win11 VM on Proxmox. This configuration has run fine for years. Recently during an upgrade to Win11 25H2 I went to test to make sure everything was functional with a quick BenchmarkReport[] but it caused the kernel to die at Test 3, FFT. Its a very repeatable failure. Just before upgrading to 25H2 I had changed my processor type for this VM to x86-64-v3 +aes from -v2 + aes. I had issues on another vm where Win11 didnt want to upgrade with v2. I didnt originally run the processor as "host" as I am running dual E5-2699v4 Xeons, Win11 doesnt support by age despite having all the instructions needed. I have used this VM with Win10 and Win11 for years running Mathematica without issue. In the past I would use BenchmarkReport[] as a quick check of functionality after any upgrades or changes. This is the first time its failed. A quick test using ParallelTable[sin[x],{x,0,pi,10^-6}] works fine A quick test of Fourier[{1, 1, 2, 2, 1, 1, 0, 0}] works fine But a simple, Needs["Benchmark`"] BenchmarkReport[] Fails while calculating Step 3, FFT. The kernel simply die with no error message or warning. If I watch carefully with Task Manager it looks like the kernel dies, Mathematica recreates the kernel, then it dies again immediately. I also tried running this command through mathscript with -verbose but it gives me no additional details why its dying. I went back and tested some older notebooks I had. One of the first ones I tried died during a NonLinearModelFit of a PieceWise function with Sin[]s. Piecewise[{ { y0 + ( A1 Sin[ 2 \[Pi] ( x - x1)/t1] Sin[ 2 \[Pi] ( x - x2)/t2] ) + A3 Sin[2 \[Pi] (x - x3)/t3], x >= xon }, {y0, x < xon} }] This had worked in the past but now it dies just like BenchmarkReport, the kernel dies with no errors. **Fixes tried** So, I set the cpu back to v2 + aes for the vm config in proxmox but the kernel still dies. Set the cpu to Host in case its an issue with AES being passed correctly but it still dies I had Ballooning memory on so I turned it off, no change I had NUMA on so I turned it off, no change I uninstalled, reinstalled Mathematica 12.0 but it still fails I installed a demo copy of Mathematica 14.3, BenchmarkReport[] and my notebook run without issue. **System Info** Running a network version of Mathematica 12.0 with MathLM on another VM for the license. License is for 2 instances and 16 kernels. The VM is running under proxmox 8.4.14. The vm was just recently upgraded to Win11 25H2 but I am not sure when I last ran BenchmarkReport[]. I have run BenchmarkReport[] on this vm multiple times with some older flavors of win11 but I cant remember when I last ran it. I had recently installed the virtio drivers for this vm on the previous Win11 version but I hadnt run Mathematica since then. Could be a contributing factor. Proxmox has gone through a recent upgrade with a reboot of the host. I hadnt tried test Mathematica afterwards. Could be a contributing factor. The vm has been tested with cpu set to Host, x86-64-v2+aes, x86-64-v3+aes, numa on and off, ballooning on and off, with 32GB memory configured for the vm. This vm is set to get 2 processors of 8 cores each, The vm is only running microsoft virtual graphic drivers and is only accessed via remote desktop, not SPICE. As far as I can tell Win11 is working as expected. I am considering a fresh install of Win11 if no better ideas surface. The host system is dual E5-2699 v4 with 512GB. The host system runs a mix of vms and containers. **Summary** I know this is probably a very weird edge case of using a VM with such an old version of Mathematica. The kernel dying does seem to fail for more than just Benchmark so its most likely not a single package responsible. The failure is limited to Mathematica 12 as far as I can tell. Just wanted to figure this our before I start embarking on a bunch of calculations. Any thoughts are appreciated. Mike Morrell 2025-10-19T19:10:08Z https://community.wolfram.com/groups/-/m/t/3558755 New feature suggestion: It would be really great if Mathematica offered a way to automatically save an enhanced version of .nb that contains, in effect, the equivalent of a .mx file with the results of all of the cells that have already been evaluated. This combination .nb/.mx file (perhaps to be called .nbx?) would avoid the time/effort required to either: (1) save a .mx file at the end of each Mathematica session and re-load it at the start of the next session, or (2) redo the evaluation of the saved .nb file at the start of each new session.

Ed Wong 2025-10-09T02:29:04Z https://community.wolfram.com/groups/-/m/t/3533938 My clipboard has bifurcated into two clipboards. The normal system clipboard and a mathematica artifact that can't be changed or deleted. The normal one follows the normal rules within mathematica, including all keyboard shortcuts and built-in functions. It can be used to copy and paste to and from mathematica and any other program. However, pasting in mathematica pastes not only the normal clipboard line but also a second line from a previous clipboard that has become stuck somewhere in some other part of mathematica I can't find or access. So you get e.g. Paste[] ~ artefact ~ a CopyToClipboard[b] Paste[] ~ artefact ~ b Travis Scott 2025-08-21T12:54:54Z https://community.wolfram.com/groups/-/m/t/3531253 I'm running *Mathematica* 14.0 on Windows: $Version (* OUTPUT: *) (* 14.0.0 for Microsoft Windows (64-bit) (December 13, 2023) *) When I create a new notebook (`File -> New -> Notebook`) in the front end, the magnification is set to 100% by default, as indicated in the bottom right-hand corner of the notebook window. **I'd like the magnification of new notebooks to instead be set to 75% by default.** Should I do this using the Options Inspector in the front end? For example, should I do the following steps (referenced [here][1]) in the Options Inspector in the front end? 1. In the front end, choose `Format -> Options Inspector...` 2. Set `Show option values` to `Global Preferences`. 3. Go to `Notebook Options -> Display Options` in the left-hand pane. 4. In the right-hand pane, change the value of `Magnification` from `1.0` to `0.75`. **Or is there another approach I should take?** [1]: https://mathematica.stackexchange.com/a/1311/ Andrew D 2025-08-15T20:58:16Z https://community.wolfram.com/groups/-/m/t/3519668 Back in the 90's I subscribed to *Mathematica in Education and Research.* Does anyone know if this is still in print or if it has been renamed?

How can i open Mathematica. mathamtica user 2025-04-24T23:20:09Z https://community.wolfram.com/groups/-/m/t/3428900 $ProcessorCount $MaxLicenseSubprocesses $MaxLicenseProcesses 14 4 2 Why am I not seeing the 12 core extension s king 2025-03-22T16:17:13Z https://community.wolfram.com/groups/-/m/t/3420785 In Mathematica 14.2 on the Mac, I inadvertently deleted a selection of text in a long text cell. And it was gone. One or two quick key presses can cause this in less than a second. Of course I was in the "zone" and so had not saved for over half an hour. Since I was writing, i wasn't evaluating any cells during this time. Lost some really nice writing. Undo was grayed out. This has happened to me before although not often. I don't think it should happen in 2025. I know there are other threads (most over 10 years old) on this subject. But I wanted to bring it forth as a current problem that still remains. If for some reason, a technical fix for undo is impossible, perhaps a simple solution could help. For example, a reminder to the user to save after a certain amount of time configured in the preferences. And clear communication with customers as to this pitfall. Paul Nielan 2025-03-20T21:25:17Z https://community.wolfram.com/groups/-/m/t/3419228 What is the difference between the `Target` and the `Evaluator` subfields in the output from `FindExternalEvaluators[]`? In the documentation for the "Python" external evaluation system, an example is given where the `Evaluator` option is set to an association that sets up a python environment by specifying a name for the environment, a python executable, dependencies, and a base directory. On the other hand, in the documentation for `ExternalEvaluate`, the `Target` option is used in one of the examples for essentially this same purpose. Note that `FindExternalEvaluators[]` reports back a both an `Evaluator` **and** a `Target` field for each entry, that in the default configuration are each set to the file path for the python executable. Since both of these fields also exist for the non-python systems, I would like to understand the intended distinction between them on a more abstract level as well. Mma Usr 2025-03-18T16:19:04Z https://community.wolfram.com/groups/-/m/t/3417574 When I hit the Run All button in this simple short testing notebook, I get the failure as shown in the picture. If I hit Run on each of the tests individually, they run successfully. I've tried restarting Mathematica and the issue still occurs. The entropy function is defined as in the comment. And since the individual tests work, that is not likely the issue. Any ideas? ![Test Notebook Failure][1] [1]: https://community.wolfram.com//c/portal/getImageAttachment?filename=Failure.jpg&userId=3094795 Paul Nielan 2025-03-16T23:14:17Z https://community.wolfram.com/groups/-/m/t/3317038 I have the following Mathematica plan: 2 activation keys (2 licences/kernels I guess) and 4 subkernels on each kernel. I'm trying to understand how it works with sockets. On the same machine I've launched 2 MathKernels. To each kernel I attached 2 pairs of "push-pull" sockets. I push `LaunchKernels[4]` on each kernel. First kernel completes the operation successfully, but the second one outputs `Unable to communicate with LinkObject`. I thought that each kernel has 4 subkernels and kernels run independently but it appears that there are 4 total subkernels. Also, I thought that Mathematica will use parallelization automatically. Let's take the first kernel. I push `Pause[10]` with the first socket and then, after a while, I push `Pause[10]`. I thought that both commands will end in 10 seconds (if kernel is busy, the second command will be passed to free subkernel). But no. Two commands run sequentially and take 20 seconds. What is the problem with subkernels? How do they work? And how to properly tell the kernel to parallelize the commands? Paul R 2024-11-09T08:29:22Z https://community.wolfram.com/groups/-/m/t/3270503 Hi, Does anyone have any suggestions regarding below. I want to create a .pkg (macOS) of Wolfram 14.1.0. The reason for accomplish that is deploy Wolfram on several computers. So I would like to deploy Wolfram on multiple macOS clients in a seamless way. The version of macOS that I am trying to create the package on (build) is macOS Sonoma 14.6.1 Packaging utilities that I use are Packages from http://s.sudre.free.fr/Software/Packages/about.html And Composer from Jam (mdm) http://s.sudre.free.fr/Software/Packages/about.html Unable to read extended attributes of item at path "/Applications/Wolfram.app/Contents/SystemFiles/Components/WSMCore/WSMCore.app/Contents/L/Modelica 4.0.0/Modelica/Clocked/BooleanSignals/Sampler/Utilities" Kind regards Micke Mikael Lindgren 2024-09-09T13:52:02Z https://community.wolfram.com/groups/-/m/t/3252066 Hi there, The attached Mathematica notebook file is coded on MacOS using Mathematica 14.0, but does not work on RP 4 and RP 5: [a related thread on the Raspberry forum][1]. I noticed that only the first output block works in Wolfram Player. As far as I know, the Mathematica on RP is a full version of Mathematica. Also, Wolfram Player must be able to execute the output cell. But why are some code snippets in input cells and the graphics in output cells incompatible in different environments? Is this a bug that will be fixed?

I first attempted to correct this issue by clearing out my cache directories as instructed here: https://support.wolfram.com/12464 however, this did not resolve the problem. When I contacted technical support, I was told that I need to set command line option -pacletreadonly but I wasn't instructed where exactly this needs to be added, and I can't find any online documentation. Could somebody please direct me to some resources on this (I'm working on a Windows OS, in case that's relevant)? Max Shpak 2024-04-24T16:41:31Z https://community.wolfram.com/groups/-/m/t/3152327 Hello, New to this community so apologies if this is the incorrect place to ask. We have users that utilize Mathematica and they need to email out of it using our hosted mail server. However, the large list of users fluctuates freqeuntly so it's been impractical to keep up with their setups. I had an idea to use the Mathematica license server as an SMTP relay that would forward to our mail server, but I'm not sure how to go about that setup. I've done some googling but haven't been able to come up with a solution. I have (what I think) is all the SMTP relay info situated in the ISS manager on the activation server, but when putting in the activation server info into the Outbound mail tab in Mathematica, it fails to send for an unspecified reason. Is there anyone out there that might have a similar setup to what I'm trying to accomplish and could point me in the right direction? Lawrence Valen 2024-04-03T17:37:39Z
