It took me 2 years between the early discussions and getting PEP 741 eventually accepted by the Steering Council: https://vstinner.github.io/pyconfig-pep-741.html C API to configure Python initialization, and C API to get and set the current runtime configuration.

I wrote PEP 757 "C API to import-export Python integers": https://discuss.python.org/t/pep-757-c-api-to-import-export-python-integers/63895 It's a public abstraction interface for gmpy2, SAGE and Python-FLINT which currently use internals (and so need to be updated frequently) or use an inefficient temporary format.

I wrote PEP 756 "Add PyUnicode_Export() and PyUnicode_Import() C functions": https://discuss.python.org/t/pep-756-c-api-add-pyunicode-export-and-pyunicode-import-c-functions/63891 It makes possible to optimize code using the limited C API to use native string formats.

New article: "Add PyUnicodeWriter C API" https://vstinner.github.io/pyunicodewriter-c-api.html New efficient & convenient API to build a Python str accepting many formats and operations. The design and implementation took 1 month. Thanks for great discussions, the final API is better and more convenient!

Bikeshedding is hard. I created a poll to decide the name of the new os.environ.refresh() method: https://discuss.python.org/t/method-to-refresh-os-environ/54774/101 "The refresh() method updates os.environ with changes to the environment made by os.putenv(), by os.unsetenv(), or made outside Python in the same process."

Oh, apparently it's a GLAMOR regression: https://gitlab.freedesktop.org/xorg/xserver/-/issues/1655 Glamor is a 2D graphics common driver for X.org. Workaround: run gvim with GVIM_ENABLE_WAYLAND=1, or put XWAYLAND_NO_GLAMOR=1 in /etc/environment.

Python 3.13 time.time() on Windows now has a resolution of 238 ns (10^-9) instead of 15.6 ms (10^-3): it's 65 500x more accurate! The feature was requested 11 years ago (2013)! Better late than never 😉 https://github.com/python/cpython/pull/116822

If you embed Python in C, please review the latest version of my PEP 741 "Python Configuration C API": https://peps.python.org/pep-0741/ Join the discussion at: https://discuss.python.org/t/pep-741-python-configuration-c-api-second-version/45403/31 I added PyConfig_Set() to set the runtime configuration and removed the Python API.

I wrote a second version of my PEP 741: Python Configuration C API: https://peps.python.org/pep-0741/

Discussion: https://discuss.python.org/t/pep-741-python-configuration-c-api-second-version/45403

List use cases, use UTF-8, simpler error handling, API to get the init config, better doc, avoid preinitialization when possible, etc.

If you embed Python in your application, I'm looking for your feedback for my PEP 741 "Python Configuration C API": https://peps.python.org/pep-0741/ Tell me how you configure Python and if you are using or plan to use the stable ABI (limited C API). Also, reviews of the PEP are welcome 😁

I decided to get my two old desktop computers from the shelf. I don't recall how to connect the monitor: ah yes, VGA! First tower has no disk, the second is the one I'm looking for: 3 disks in RAID. It took me a while to remind the password. Last login in April 2020! Fedora 27!

Apparently, I'm only using a single computer for 4 years: my laptop. I have Nintendo Switch and PlayStation 5 to play video games. I don't know the purpose of these 2 bags full of old cables.
