the Quite Universal Circuit Simulator, a ten-year-old GUI GPL program that lets you draw #analog circuits and simulate them using #SPICE. #hardware #simulation
An overview of #linear-equations solving.
a #paper on #linear-equations #constraint solving, about when Gauss-Seidel converges and when it doesn’t, and showing an extended version of Gauss-Seidel with guaranteed convergence to the least-norm solution in the underdetermined case. Also shows that in the overconstrained case, bog-standard randomized Gauss-Seidel converges to the least-squares solution!
The LMMS digital #audio workstation free-software project has a bunch of downloadable samples, including this grand-piano sample, under free licenses. Also thousands of LMMS “projects”, which I guess is like your entire LMMS workspace setup, categorized by musical genre. The samples are useful even if you don’t have LMMS.
