   SageMath's goal is to provide a viable free open source alternative to Magma, Maple, Mathematica, and Matlab

   I started SageMath in 2004 to provide a FOSS alternative to expensive commercial mathematics software. Sage is Python-based and has had around 600 volunteer contributors. The project has also received millions of dollars in support from grants around the world, and has a very active developer community.

   This site is about Software as a Service, and there are at least two easy ways to use Sage online as a service:

   https://cocalc.com and https://sagecell.sagemath.org/

   🏁 Competitors: Wolfram Mathematica, MATLAB, Maple, Magma

• Is there some kind of CAD program you can design Mujoco MJCF XML files in?

  The most famous and complete free sim for actual natural body parts is https://simtk.org/projects/opensim. Source: over 2 years ago

• How to use Motion Capture Data on OpenSim - Help!

  Hi, I take it you're meaning opensim which models musculoskeletal structures and creates dynamic simulations of movement rather than opensimulator. Source: over 2 years ago

• Ask HN: What problem are you close to solving and how can we help?

  My research specialty is biomechanics. For the arm motion thing, it sounds like you might want inverse kinematics or inverse dynamics. Take a look at OpenSim: https://simtk.org/projects/opensim For the oral appliance adjustment, I'm not sure what your output measures of interest are. If they're mechanical maybe you want to do a sensitivity analysis using FEA. Maybe look at FEBio: https://febio.org/ As for... - Source: Hacker News / over 2 years ago

• OpenSim issues

  The first link you shared doesn’t take me to the same spot I downloaded the models from. This link: https://simtk.org/projects/opensim should take you to the home site. Click “download latest releases” drop down and select “models and examples”. This is how I got them, should be in a zip file under “modules”. Hope this helps! Also I have struggled with a lot of different issues using Opensim for gait Lab marker... Source: over 2 years ago

• Did studying proof based math topics e.g. analysis make you a better programmer?

  I received a Ph.D. In pure math (number theory) from Berkeley, and then worked as an academic mathematician for 20 years, so wrote a few dozen research papers and some books. My ability to write software for doing mathematics was obviously better as a result of studying mathematics, e.g., I started SageMath (https://sagemath.org) and wrote a big chunk of it. Now I mostly do full stack web development (I... - Source: Hacker News / 11 months ago

• How do I get this calculator to give me the derivative?

  You could also try sagemath (sagemath.org), available for window, mac & linux for free. Source: about 1 year ago

• Are there any good free numeric computing environments?

  SageMath gets my vote. I use it to compute simplicial objects that turn out to be infinitely categories. https://sagemath.org SageMath includes most of the python libraries already mentioned, and much more. Source: over 1 year ago

  I am a fan of this site (and of this site's tutorial in particular). I would also recommend this site. The SageMath site has some good tutorials too. Source: over 1 year ago
