PyConZA 2021 - Second call for submissions
by Neil Muller July 12, 2021

July 12, 2021

This is a second call for talk proposals for PyConZA 2021. While we've already received several great talk proposals, we still have a number of open talk slots and are thus keen to see further talk submissions. PyCon ZA 2021 will take place on the 7th & 8th of October, 2021. This year, due to the ongoing pandemic, PyCon ZA will again be an online event. We will be streaming the talks and using discord for discussion around the talks and other conference activities. We are looking for the following presentations: - Keynotes (45 minute long talks on a subject of general interest) - Talks (30 minute long talks on more specific topics) If you would like to give a presentation, please register at https://za.pycon.org/ and submit your proposal, following the instructions at https://za.pycon.org/talks/submit-talk/ . We have a number of tracks available, including: Data Science, Teaching and Learning with Python, Web, Scientific Computing, Testing and Other (which includes all talks that don't fall under the mentioned tracks). We hope to notify accepted presenters by no later than the 31st of August 2021. Speakers will be expected to be available after the presentation for a short Q&A session. Shared sessions are also possible. The presentations will be in English. PyCon ZA offers a mentorship program for inexperienced speakers. If you would like assistance preparing your submission, email team(a)za.pycon.org with a rough description of what you would like to talk about and we'll find a suitable experienced speaker to act as a mentor. If you want to present something that doesn't fit into the two talk categories at PyCon ZA, please contact the organising committee at team(a)za.pycon.org so we can discuss whether that will be feasible. -- Neil Muller On behalf of the PyConZA organising committee

[RELEASE] Python 3.10.0b4 is available
by Pablo Galindo Salgado July 11, 2021

July 11, 2021

Wow! A release on a Saturday? Do the release management team even rest? You better believe it, because this is the last of the planned beta releases. This means that the next pre-release will be the first release candidate of Python 3.10.0. Remember that our goal is to have no ABI changes after this beta and a few code changes as possible after 3.10.0rc1. https://www.python.org/downloads/release/python-3100b4/ #This is a beta preview of Python 3.10 Python 3.10 is still in development. 3.10.0b4 is the fourth and last of the beta release previews. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. We strongly encourage maintainers of third-party Python projects to test with 3.10 during the beta phase and report issues found to the Python bug tracker as soon as possible. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (Monday, 2021-08-02). Our goal is to have no ABI changes after beta 4 and as few code changes as possible after 3.10.0rc1, the first release candidate. To achieve that, it will be extremely important to get as much exposure for 3.10 as possible during the beta phase. Please keep in mind that this is a preview release and its use is not recommended for production environments. The next pre-release, the first release candidate of Python 3.10.0, will be 3.10.0rc1. It is currently scheduled for Monday, 2021-08-02. #And now for something completely different In quantum physics, the spin is an intrinsic form of angular momentum carried by elementary particles, composite particles, and atomic nuclei. The spin is one of two types of angular momentum in quantum mechanics, the other being orbital angular momentum. The orbital angular momentum operator is the quantum-mechanical counterpart to the classical angular momentum of orbital revolution and appears when there is periodic structure to its wavefunction as the angle varies. For photons, spin is the quantum-mechanical counterpart of the polarization of light; for electrons, the spin has no classical counterpart. # 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. Regards from very cloudy London, Your friendly release team, Pablo Galindo @pablogsal Ned Deily @nad Steve Dower @steve.dower

NetworkX 2.6.1 released
by Jarrod Millman July 8, 2021

July 8, 2021

I am happy to announce NetworkX 2.6.1 (2.6.0 had a minor issue)! This release has a larger than normal number of changes in preparation for the upcoming 3.0 release. The current plan is to release 2.7 near the end of summer and 3.0 in late 2021. The focus of the 3.0 release is on addressing years of technical debt and making it easier to contribute. The 2.6 release deprecates over 30 functions. It also makes major changes to our default dependencies. We no longer depend on the "decorator" library. More importantly, NumPy, SciPy, Matplotlib, and Pandas are now default requirements. While we've made these core libraries of the scientific Python ecosystem default dependencies, much of NetworkX still works without these libraries and we expect that to continue. Be assured that we test NetworkX with and without the dependencies, so if you do **not** use functions that depend on external libraries you can install NetworkX using pip with the `--no-deps` flag. This release supports Python 3.7-3.9 and contains many new features. It is the result of almost a year of work with over 363 pull requests by 91 contributors. If you have code that imports NetworkX, please take some time to check that you are able to update your code to work with the new release. The 2.6 release announcement is here: https://networkx.org/documentation/stable/release/release_2.6.html For more information, please visit our website - http://networkx.org and our gallery of examples - https://networkx.org/documentation/latest/auto_examples/index.html Best regards, Jarrod

[ANN] Austin -- CPython frame stack sampler v3.0.0 is now available
by Gabriele Tornetta July 2, 2021

July 2, 2021

I am delighted to announce the release 3.0.0 of Austin. If you haven't heard of Austin before, it is an open-source frame stack sampler for CPython, distributed under the GPLv3 license. It can be used to obtain statistical profiling data out of a running Python application without a single line of instrumentation. This means that you can start profiling a Python application straight away, even while it's running in a production environment, with minimal impact on performance. The best way to leverage Austin is to use the new extension for VS Code, which brings interactive flame graphs straight into the text editor to allow you to quickly jump to the source code with a simple click. You can find the extension on the Visual Studio Marketplace and install it directly from VS Code: https://marketplace.visualstudio.com/items?itemName=p403n1x87.austin-vscode To see how to make the best of Austin with VS Code to find and fix performance issues, check out this blog post, which shows you the editor extension in action on a real Python project: https://p403n1x87.github.io/how-to-bust-python-performance-issues.html The latest release comes with many improvements, including a re-worked sleepless mode that now gives an estimate of CPU time, initial support for Python 3.10, better support for Python-based binaries like gunicorn, uWSGI, etc. on all supported platforms. Austin is a pure C application that has no dependencies other than the C standard library. Its source code is hosted on GitHub at https://github.com/P403n1x87/austin The README contains installation and usage details, as well as some examples of Austin in action. Details on how to contribute to Austin's development can be found at the bottom of the page. Austin can be installed easily on the following platforms and from the following sources: Linux: - Snap Store - Debian repositories macOS: - Homebrew Windows: - Chocolatey - Scoop An Austin image, based on Ubuntu 20.04, is also available from Docker Hub: https://hub.docker.com/r/p403n1x87/austin Austin is also simple to compile from sources as it only depends on the standard C library, if you don't have access to the above-listed sources. You can stay up-to-date with the project's development by following Austin on Twitter (https://twitter.com/AustinSampler). All the best, Gabriele <phoenix1987(a)gmail.com> <p><a href="https://github.com/P403n1x87/austin">Austin 3.0.0</a> - frame stack sampler for CPython. (02-Jul-21)</p>
