What's the schedule for the core sprint?
by Eric V. Smith Oct. 19, 2021

Oct. 19, 2021

I'm traveling and I don't know when I'll be free. If there's a schedule of any events, I'll try and make some of those. Also, any instructions for Discord (URL, how to get to the core sprint channel(s)) would be appreciated. I don't know much about Discord. Thanks.

Dates for the core dev sprints
by Brett Cannon Oct. 11, 2021

Oct. 11, 2021

Based on the results of the poll on discuss.python.org, the core dev sprints will be from October 18 - 24. Based on feedback from last year and for simplicity reasons, the sprints will be hosted on the core dev Discord server (link in the Inquisition category on discuss.python.org to keep it private to core devs only; also don't forget to record your Discord username, which is formatted as r".+#\d+", to https://github.com/python/voters/ if you have not already). We currently have no organizer(s) for this, so right now this will be self-organized on the spot. 😅 If anyone wants to volunteer to run the sprints then please let the SC know.

Opting-in for Hacktoberfest
by Mariatta Oct. 8, 2021

Oct. 8, 2021

Hello, I would like to propose that we opt-in the CPython project for Hacktoberfest this year, by adding the hacktoberfest topic on the GitHub repository. https://hacktoberfest.digitalocean.com/ Hacktoberfest is an annual event organized by Digital Ocean, now in the 8th year, where aspiring contributors are encouraged to contribute to open source projects. I'm a member of the Hacktoberfest Advisory council <https://hacktoberfest.digitalocean.com/advisory-council> this year. As council members, we discussed the focus on maintainers and rewarding maintainers for their participation. This year, maintainers can also get rewarded for helping to review pull requests that come during this month. Additionally, participating projects can get listed in their "Giving <https://hacktoberfest.digitalocean.com/giving>" page, where people can find projects to donate to. It would be great for CPython to be listed there so people can donate through GitHub Sponsors. In order to participate, we need to add the "hacktoberfest" topic on the repo, it will signify that we're accepting hacktoberfest contributions. If you, as core developers, want to be rewarded for hacktoberfest (get a commemorative t-shirt, or have a tree planted on your behalf), then you can sign up here: https://hacktoberfest.digitalocean.com/ (choose to sign up as maintainer). This is totally optional. I know you're all already reviewing PRs anyway. Yes we may receive increased PRs, if you don't have the bandwidth of reviewing additional PRs, you don't have to try to increase your capacity. Just continue doing what you're already doing. In the past, we did receive quite a number of spam/invalid PRs in this month, which led to projects having to opt-in for hacktoberfest. Since projects have to opt-in, it reduces the number of projects people can contribute to. I'm hoping that CPython can opt-in this year and be welcoming of hacktoberfest contributions. I would suggest that we opt-in for at least a week. If we do see many spammy PRs, then let's opt out of it. If not, we can continue. I do have the ability to add/remove hacktoberfest topic myself, so if we're okay with this, I can go ahead and do it. I will also remove the topic once the month ended. To reiterate: - As core devs, you don't have to do anything more. Continue doing what you're doing now. - As core devs, it is optional for you to sign up for Hacktoberfest. If you do sign up, you could receive commemorative t-shirt, or have a tree planted on your behalf - By opting in, we can get listed in Hacktoberfest's giving page, to give exposure to our GitHub Sponsors page - We may see more spammy PRs. If this becomes an issue, we'll opt-out. Let me know if you have any concerns. I'll wait till Friday, if there's no strong objection, I will proceed with opting in. Thanks.

[RELEASE] Python 3.11.0a1 is available
by Pablo Galindo Salgado Oct. 7, 2021

Oct. 7, 2021

Now that we are on a release spree, here you have the first alpha release of Python 3.11: Python 3.11.0a1. Let the testing and validation games begin! https://www.python.org/downloads/release/python-3110a1/ *Major new features of the 3.11 series, compared with 3.10* Python 3.11 is still in development. This release, 3.11.0a1 is the first of six planned alpha releases. Alpha releases are intended to make it easier to test the current state of new features and bug fixes and to test the release process. During the alpha phase, features may be added up until the start of the beta phase (2022-05-06) and, if necessary, may be modified or deleted up until the release candidate phase (2022-08-01). Please keep in mind that this is a preview release and its use is not recommended for production environments. Many new features for Python 3.11 are still being planned and written. Among the new major new features and changes so far: - PEP 657 <https://www.python.org/dev/peps/pep-0657/> – Include Fine-Grained Error Locations in Tracebacks - PEP 654 <https://www.python.org/dev/peps/pep-0654/> – PEP 654 – Exception Groups and except* - (Hey, fellow core developer, if a feature you find important is missing from this list, let Pablo know <pablogsal(a)python.org>.) The next pre-release of Python 3.11 will be 3.11.0a2, currently scheduled for 2021-11-02. *And now for something completely different* Zero-point energy is the lowest possible energy that a quantum mechanical system may have. Unlike in classical mechanics, quantum systems constantly fluctuate in their lowest energy state as described by the Heisenberg uncertainty principle. As well as atoms and molecules, the empty space of the vacuum has these properties. According to quantum field theory, the universe can be thought of not as isolated particles but as continuous fluctuating fields: matter fields, whose quanta are fermions (i.e., leptons and quarks), and force fields, whose quanta are bosons (e.g., photons and gluons). All these fields have a non zero amount of energy called zero-point energy. Physics currently lacks a full theoretical model for understanding zero-point energy; in particular, the discrepancy between theorized and observed vacuum energy is a source of major contention *We hope you enjoy those new releases!* Thanks to all of the many volunteers who help make Python Development and these releases possible! Please consider supporting our efforts by volunteering yourself or through organization contributions to the Python Software Foundation.

Thanks for your work in Python 3.10
by Pablo Galindo Salgado Oct. 5, 2021

Oct. 5, 2021

Hi everyone, Now that 3.10.0 is finally released I wanted to take the time to thank you all for all your fantastic work this past year. Is because of the sum of all your fantastic work that Python 3.10 is going to be such a fantastic release. No matter if you have been working in fixing bugs, adding features, improving the documentation, reviewing contributor PRs, helping with the infrastructure, helping with the buildbot fleet, triaging bugs or discussing PEPs and features, your work is tremendously appreciated: you make a tremendous impact in Python and its community. I also wanted to make sure to thank again all the people that helped with the release itself and with the numerous release blockers and also for your patience when I had to delay your feature to 3.11 or your bugfix to 3.10.1. It has been a privilege to be able to release the result of your work to the community! Thank you all, your work really makes a difference. Regards from sunny London, Pablo Galindo Salgado

[RELEASE] Python 3.10.0 is available
by Pablo Galindo Salgado Oct. 4, 2021

Oct. 4, 2021

On behalf of the Python development community and the Python 3.10 release team, I’m pleased to announce the availability of Python 3.10.0. Python 3.10.0 is the newest major release of the Python programming language, and it contains many new features and optimizations. https://www.python.org/downloads/release/python-3100/ # Major new features of the 3.10 series, compared to 3.9 Among the new major new features and changes so far: * [PEP 623](https://www.python.org/dev/peps/pep-0623/) -- Deprecate and prepare for the removal of the wstr member in PyUnicodeObject. * [PEP 604](https://www.python.org/dev/peps/pep-0604/) -- Allow writing union types as X | Y * [PEP 612](https://www.python.org/dev/peps/pep-0612/) -- Parameter Specification Variables * [PEP 626](https://www.python.org/dev/peps/pep-0626/) -- Precise line numbers for debugging and other tools. * [PEP 618 ](https://www.python.org/dev/peps/pep-0618/) -- Add Optional Length-Checking To zip. * [bpo-12782](https://bugs.python.org/issue12782): Parenthesized context managers are now officially allowed. * [PEP 632 ](https://www.python.org/dev/peps/pep-0632/) -- Deprecate distutils module. * [PEP 613 ](https://www.python.org/dev/peps/pep-0613/) -- Explicit Type Aliases * [PEP 634 ](https://www.python.org/dev/peps/pep-0634/) -- Structural Pattern Matching: Specification * [PEP 635 ](https://www.python.org/dev/peps/pep-0635/) -- Structural Pattern Matching: Motivation and Rationale * [PEP 636 ](https://www.python.org/dev/peps/pep-0636/) -- Structural Pattern Matching: Tutorial * [PEP 644 ](https://www.python.org/dev/peps/pep-0644/) -- Require OpenSSL 1.1.1 or newer * [PEP 624 ](https://www.python.org/dev/peps/pep-0624/) -- Remove Py_UNICODE encoder APIs * [PEP 597 ](https://www.python.org/dev/peps/pep-0597/) -- Add optional EncodingWarning [bpo-38605](https://bugs.python.org/issue38605): `from __future__ import annotations` ([PEP 563](https://www.python.org/dev/peps/pep-0563/)) used to be on this list in previous pre-releases but it has been postponed to Python 3.11 due to some compatibility concerns. You can read the Steering Council communication about it [here]( https://mail.python.org/archives/list/python-dev@python.org/thread/CLVXXPQ2…) to learn more. # More resources * [Changelog](https://docs.python.org/3.10/whatsnew/changelog.html#changelog ) * [Online Documentation](https://docs.python.org/3.10/) * [PEP 619](https://www.python.org/dev/peps/pep-0619/), 3.10 Release Schedule * Report bugs at [https://bugs.python.org](https://bugs.python.org). * [Help fund Python and its community](/psf/donations/). # And now for something completely different For a Schwarzschild black hole (a black hole with no rotation or electromagnetic charge), given a free fall particle starting at the event horizon, the maximum propper time it will experience to fall into (which happens when it falls without angular velocity) the singularity is `π*M` (in [natural units](https://en.wikipedia.org/wiki/Natural_units)), where M is the mass of the black hole. For Sagittarius A* (the black hole at the center of the milky way) this time is approximately 1 minute. Schwarzschild black holes are also unique because they have a space-like singularity at their core, which means that the singularity doesn't happen at a specific point in *space* but happens at a specific point in *time* (the future). This means once you are inside the event horizon you cannot point with your finger towards the direction the singularity is located because the singularity happens in your future: no matter where you move, you will "fall" into it. # We hope you enjoy the new releases!

Do I qualify for a xx@python.org email
by Joannah Nanjekye Oct. 2, 2021

Oct. 2, 2021

Am migrating slowly away from using my Gmail address which I use for CPython correspondence and development. I plan to use my university email in the interim, when I graduate it will be a different story, I may lose it. So do I qualify for an xxx(a)python.org email for purposes of CPython development? If so, who is responsible for coordinating this? -- Best, Joannah Nanjekye *"You think you know when you learn, are more sure when you can write, even more when you can teach, but certain when you can program."
