Hi, Recently, I wrote reports of my CPython contributions since 1 year 1/2. Some people on this list might be interested, so here is the list. I was also asked for more documentation about my work on FASTCALL and its effect on performance. You can expect more article on FASTCALL later, especially on its API and its implementaiton. == CPython contrib 2016 == My contributions to CPython during 2016 Q1: https://haypo.github.io/contrib-cpython-2016q1.html My contributions to CPython during 2016 Q2: https://haypo.github.io/contrib-cpython-2016q2.html PEP 524: os.urandom() now blocks on Linux in Python 3.6: https://haypo.github.io/pep-524-os-urandom-blocking.html CPython sprint, september 2016: https://haypo.github.io/cpython-sprint-2016.html My contributions to CPython during 2016 Q3: https://haypo.github.io/contrib-cpython-2016q3.html My contributions to CPython during 2016 Q4: https://haypo.github.io/contrib-cpython-2016q4.html == FASTCALL project == The start of the FASTCALL project: https://haypo.github.io/start-fastcall-project.html FASTCALL microbenchmarks: https://haypo.github.io/fastcall-microbenchmarks.html FASTCALL issues: https://haypo.github.io/fastcall-issues.html == CPython contrib 2015 == My contributions to CPython during 2015 Q3: https://haypo.github.io/contrib-cpython-2015q3.html My contributions to CPython during 2015 Q4: https://haypo.github.io/contrib-cpython-2015q4.html Victor
