Hi, I contribute to a number of projects that require incredibly specific information to facilitate (GPGPU kernel optimizations and unit tests for BLAS) and I use Reddit to collaborate with other engineers to solve issues like doing calculus on Lie groups resulting in a divide by zero because some non-zero groups multiplying to zero in the middle of the calculation. The best engineers and mathematicians I know moved here, so I moved with them to continue the dissemination of these principles.
