What non-FOSS software are you using that you wish you could replace?
For me its honestly a ton of my work software (digital forensics), shit is too niche to be replaced by good FOSS options. Cellebrite, Magnet Axiom, etc. Autopsy is great and free and has a linux version but it simply cannot get the same level of data without a pretty nutty level of custom code.
And the biggest side effect of this is FUCKING WINDOWS. God I would replace this nightmare OS in a heartbeat if the aforementioned work software would make linux compatible versions. We have legitimately wasted 10k hours dealing with windows bullshit that would not be a problem in linux. Though im sure linux would take a different 10k for its own problems.
What about you guys? Doesn't have to be work related, thats just the thorn in my side right now.
Mechanical CAD. Something like SolidWorks or Fusion 360.
FreeCAD just isn't there yet. They're still struggling with the topological naming problem. However, Blender was like this in the field of 3D animations. Now it's the standard. That gives me hope for FreeCAD. Anyway, MCAD is very important. I'm learning modern C++ and the FreeCAD code base in order to contribute.
I also wish there was a better CAD kernel than OpenCASCADE.
I have been experimenting with using Inkscape and OpenSCAD for 3d modeling, and it seems to work for what I do, but I know quite a few people prefer a more graphical interface than OpenSCAD.
OpenSCAD is a good take on CAD. My primary workflow is also based on plaintext (text configs, code, org-mode, latex, etc) and keyboard (no mouse). It's easy to manage and back it up with version control tools like git. However, there are a few fields that I feel are inherently visual and need a very interactive tool. CAD is one of them. Others are 3D animation and art.
