From sebastian at sipsolutions.net Thu Oct 3 17:54:19 2019 From: sebastian at sipsolutions.net (Sebastian Berg) Date: Thu, 03 Oct 2019 14:54:19 -0700 Subject: [AstroPy] =?utf-8?q?Accepting_NEP_29_=E2=80=94_Recommend_Python_?= =?utf-8?q?and_Numpy_version_support_as_a_community_policy_standard?= Message-ID: Hi all, we propose formally accepting the NumPy enhancement proposal 29: "Recommend Python and Numpy version support as a community policy standard" available at: https://numpy.org/neps/nep-0029-deprecation_policy.html If there are no objections within a week it may be accepted. This proposal is a recommendation to the larger ecosystem and thus should receive attention and acceptance from a wide audience. However, lets try to keep discussions on the NumPy mailing list. The most important points from the Abstract and Implementation sections are: "This NEP recommends that all projects across the Scientific Python ecosystem adopt a common ?time window-based? policy for support of Python and NumPy versions. Standardizing a recommendation for project support of minimum Python and NumPy versions will improve downstream project planning. ?" and: "We suggest that all projects adopt the following language into their development guidelines: This project supports: * All minor versions of Python released 42 months prior to the project, and at minimum the two latest minor versions. * All minor versions of numpy released in the 24 months prior to the project, and at minimum the last thee minor versions." For the full text, please refer to the link above. Cheers, Sebastian -------------- next part -------------- A non-text attachment was scrubbed...

If you want to help in libraries, there are many of them, and indeed contributing to astropy is a very good way. However it cannot make a living, because it is a free open-source package and you won't be paid for that (if I'm wrong, please correct me). If you want to do research in astronomy/astrophysics, you will probably need to take one more master, to have a degree in astophysics (take care : it need a lots of physics knowledge). Most of the time you don't find a permanent job without having also a PhD, but it may be easier for engineers. Sometimes, for groups working in hughe simulations or domains that require delicate high-level coding (cosmology, magneto-hydrodynamic simulations, etc...) groups can search for a developper/informatician with background or at least interest in astrophysics. There are also lots of data treatment and database organisation, and you can postulate for that. There is a lot of coding and informatic work in astrophysics, but most of the time it is done by astrophysicists themselves. This field is funded by states, and as it doesn't produce directly benefits we don't have a lot of funding, so there is no money to hire specialists in informatics, even if it would be better. So My advice would be to take more lessons, that at least give you an official level in astrophysics, and postulate in simulation and large data treatment. And be ready to travel a lot, too.

They are available on PyPI or on the usual conda channels. The primary reason for the new releases is to provide a workaround for the prolonged maintenance period of the USNO servers that serves the IERS updates (that multiple modules of astropy relies on). Full changelogs can be found at the following links: https://github.com/astropy/astropy/blob/v3.2.3/CHANGES.rst and https://github.com/astropy/astropy/blob/v2.0.16/CHANGES.rst Thanks for everyone who contributed for a quick turnaround for these releases.

In desperation, I eventually uninstalled and re-installed MacPorts entirely (according to their recipe at https://guide.macports.org/chunked/installing.macports.uninstalling.html), which totally zaps /opt/local, and then _only_ re-installed python3.5 and py35-astropy (and the corresponding other packages needed automatically).

Can you update to e.g. Python 3.6 or 3.7? Even if your macOS version is old, it should be possible with either Macports or Anaconda. sudo port install py37-astropy Christoph
