ANN: A new version (0.4.1) of python-gnupg has been released.
by Vinay Sajip 10 Jul '17

10 Jul '17

A new version of the Python module which wraps GnuPG has been released. What Changed? ============= This is an enhancement and bug-fix release, and all users are encouraged to upgrade. See the project website [1] for more information. Brief summary: * Updated message handling logic to no longer raise exceptions when a message isn't recognised. Thanks to Daniel Kahn Gillmor for the patch. * Always use always use --fixed-list-mode, --batch and --with-colons. Thanks to Daniel Kahn Gillmor for the patch. * Improved scan_keys() handling on GnuPG >= 2.1. Thanks to Daniel Kahn Gillmor for the patch. * Improved test behaviour with GnuPG >= 2.1. Failures when deleting test directory trees are now ignored. Thanks to Daniel Kahn Gillmor for the patch. * Added close_file keyword argument to verify_file to allow the file closing to be made optional. Current behaviour is maintained - close_file=False can be passed to skip closing the file being verified. * Added the extra_args keyword parameter to allow custom arguments to be passed to the gpg executable. * Instances of the GPG class now have an additional on_data attribute, which defaults to None. It can be set to a callable which will be called with a single argument - a binary chunk of data received from the gpg executable. The callable can do whatever it likes with the chunks passed to it - e.g. write them to a separate stream. The callable should not raise any exceptions (unless it wants the current operation to fail). This release [2] has been signed with my code signing key: Vinay Sajip (CODE SIGNING KEY) <vina... at yahoo.co.uk> Fingerprint: CA74 9061 914E AC13 8E66 EADB 9147 B477 339A 9B86 What Does It Do? ================ The gnupg module allows Python programs to make use of the functionality provided by the Gnu Privacy Guard (abbreviated GPG or GnuPG). Using this module, Python programs can encrypt and decrypt data, digitally sign documents and verify digital signatures, manage (generate, list and delete) encryption keys, using proven Public Key Infrastructure (PKI) encryption technology based on OpenPGP. This module is expected to be used with Python versions >= 2.4, as it makes use of the subprocess module which appeared in that version of Python. This module is a newer version derived from earlier work by Andrew Kuchling, Richard Jones and Steve Traugott. A test suite using unittest is included with the source distribution. Simple usage: >>> import gnupg >>> gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory') >>> gpg.list_keys() [{ ... 'fingerprint': 'F819EE7705497D73E3CCEE65197D5DAC68F1AAB2', 'keyid': '197D5DAC68F1AAB2', 'length': '1024', 'type': 'pub', 'uids': ['', 'Gary Gross (A test user) <gary.gr... at gamma.com>']}, { ... 'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A', 'keyid': '0C5FEFA7A921FC4A', 'length': '1024', ... 'uids': ['', 'Danny Davis (A test user) <danny.da... at delta.com>']}] >>> encrypted = gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A']) >>> str(encrypted) '-----BEGIN PGP MESSAGE-----\nVersion: GnuPG v1.4.9 (GNU/Linux)\n \nhQIOA/6NHMDTXUwcEAf . -----END PGP MESSAGE-----\n' >>> decrypted = gpg.decrypt(str(encrypted), passphrase='secret') >>> str(decrypted) 'Hello, world!' >>> signed = gpg.sign("Goodbye, world!", passphrase='secret') >>> verified = gpg.verify(str(signed)) >>> print "Verified" if verified else "Not verified" 'Verified' As always, your feedback is most welcome (especially bug reports [3], patches and suggestions for improvement, or any other points via the mailing list/discussion group [4]). Please refer to the documentation [5] for more information. Enjoy! Cheers Vinay Sajip Red Dove Consultants Ltd.

ANN: TEXTCOMBINE-SP
by Mok-Kong Shen 09 Jul '17

09 Jul '17

An estimate of entropy of English texts is 1.34 bits per letter [1]. This implies that, if the letters are coded into 5 bits, one needs to appropriately combine 4 text files in order to obtain bit sequences of full entropy, since 4*1.34 = 5.36 > 5. The method used in our software is to sum (mod 32) the coded values of a-z (mapped to 0-25) as 5 bits of the corresponding letters of the text files. There are plenty of other schemes for obtaining high quality pseudo-random sequences in practice, e.g. AES in counter mode. However our scheme seems to be much simpler both in the underlying logic (understandability) and in implementation and is thus a viable alternative that one could use/need under circumstances. The software is available at mok-kong-shen.de M. K. Shen ------------------------------------------------------------------------ [1] T. M. Cover, R. C.

ANN: Astropy v2.0 released
by Erik Tollerud 08 Jul '17

08 Jul '17

Dear colleagues, We are very happy to announce the v2.0 release of the Astropy package, a core Python package for Astronomy: http://www.astropy.org Astropy is a community-driven Python package intended to contain much of the core functionality and common tools needed for astronomy and astrophysics. New and improved major functionality in this release includes: * Most models now support parameters having units (i.e., being Quantity objects). * A new CCDData class that is directly useful for typical astronomical images and implements the NDData interface. * Coordinate frame objects can now carry proper motions and radial velocities, and will carry them through and transform them between frames. (This functionality is experimental and feedback is greatly desired.) * Many of the typical mixin columns for astropy tables can now be saved into ECSV files and fully round-tripped. * The fft and direct versions of the convolution algorithm in astropy.convolution are now more consistent and work better with typical use cases. * A variety of additions to the astropy.stats subpackage In addition, hundreds of smaller improvements and fixes have been made. An overview of the changes is provided at: http://docs.astropy.org/en/stable/whatsnew/2.0.html Note that the Astropy 2.x series will be the last versions of Astropy that will support Python 2.x. Future versions of Astropy will only support Python 3.x. Instructions for installing Astropy are provided on our website, and extensive documentation can be found at: http://docs.astropy.org If you make use of the Anaconda Python Distribution, you can update to Astropy v2.0 with: conda update astropy If you normally use pip, you can upgrade with: pip install astropy --upgrade Please report any issues, or request new features via our GitHub repository: https://github.com/astropy/astropy/issues Over 232 developers have contributed code to Astropy so far, and you can find out more about the team behind Astropy here: http://www.astropy.org/team.html Astropy v2.0 now repaces v1.0 as the long term support release, and will be supported until the end of 2019. The next major release of Astropy (scheduled for January 2018) will only support Python 3.x. So if you need to use Astropy in a very stable environment in Python 2.7, you should continue to use the 2.0.x series after 3.0.x is released. If you use Astropy directly for your work, or as a dependency to another package, please remember to include the following acknowledgment at the end of papers: “This research made use of Astropy, a community-developed core Python package for Astronomy (Astropy Collaboration, 2013).” where (Astropy Collaboration, 2013) is a reference to the Astropy paper: http://dx.doi.org/10.1051/0004-6361/201322068 Please feel free to forward this announcement to anyone you think might be interested in this release! The announcement can also be found online at http://www.astropy.org/announcements/release-2.0.html. Special thanks to the coordinator for this release: Brigitta Sipocz.

NumPy 1.13.1 released
by Charles R Harris 07 Jul '17

07 Jul '17

Hi All, On behalf of the NumPy team, I am pleased to announce the release of NumPy 1.13.1. This is a bugfix release for problems found in 1.13.0. The major changes are: - fixes for the new memory overlap detection, - fixes for the new temporary elision capability, - reversion of the removal of the boolean binary ``-`` operator. It is recommended that users of 1.13.0 upgrade to 1.13.1. Wheels can be found on PyPI <https://pypi.python.org/pypi/numpy>. Source tarballs, zipfiles, release notes, and the changelog are available on github <https://github.com/numpy/numpy/releases/tag/v1.13.1>. Note that the wheels for Python 3.6 are built against 3.6.1, hence will not work when used with 3.6.0 due to Python bug #29943 <https://bugs.python.org/issue29943>. The plan is to release NumPy 1.13.2 shortly after the release of Python 3.6.2 is out with a fix that problem. If you are using 3.6.0, the workaround is to upgrade to 3.6.1 or use an earlier Python version. *Pull requests merged*A total of 19 pull requests were merged for this release. * #9240 DOC: BLD: fix lots of Sphinx warnings/errors. * #9255 Revert "DEP: Raise TypeError for subtract(bool_, bool_)." * #9261 BUG: don't elide into readonly and updateifcopy temporaries for... * #9262 BUG: fix missing keyword rename for common block in numpy.f2py * #9263 BUG: handle resize of 0d array * #9267 DOC: update f2py front page and some doc build metadata. * #9299 BUG: Fix Intel compilation on Unix. * #9317 BUG: fix wrong ndim used in empty where check * #9319 BUG: Make extensions compilable with MinGW on Py2.7 * #9339 BUG: Prevent crash if ufunc doc string is null * #9340 BUG: umath: un-break ufunc where= when no out= is given * #9371 DOC: Add isnat/positive ufunc to documentation * #9372 BUG: Fix error in fromstring function from numpy.core.records... * #9373 BUG: ')' is printed at the end pointer of the buffer in numpy.f2py. * #9374 DOC: Create NumPy 1.13.1 release notes. * #9376 BUG: Prevent hang traversing ufunc userloop linked list * #9377 DOC: Use x1 and x2 in the heaviside docstring. * #9378 DOC: Add $PARAMS to the isnat docstring * #9379 DOC: Update the 1.13.1 release notes *Contributors* A total of 12 people contributed to this release.

aiosmtpd 1.1
by Barry Warsaw 06 Jul '17

06 Jul '17

Hi! On behalf of all the developers, I'm very happy to announce the release of aiosmtpd 1.1. aiosmtpd is a re-implementation of the stdlib smtpd.py module on top of the asyncio framework. It is compliant with the relevant RFCs (5321, 2033, etc.) and supports both SMTP (Simple Mail Transport Protocol) and LMTP (Local Mail Transport Protocol) out of the box. It provides for running the server both from Python and the command line, and it is extensible both by subclassing and by implementing your own "event handlers". aiosmtpd is compatible with Python 3.5 and 3.6. Changes in 1.1 include: * Dropped support for Python 3.4. Yay for async/await! * Better support for RFC 5321. This includes a minor backward incompatibility: if your handler implements handle_NOOP(), the method must now accept an argument. * Much better support for HELP, including adding a decorator that allows SMTP subclasses to control what shows up in HELP. * General improvements to the command line, including adding a manpage. * General improvements and enhancements in the Controller class. * Fixes to several issues around STARTTLS. Much thanks goes to all our fine contributors! Project home: https://github.com/aio-libs/aiosmtpd Report bugs at: https://github.com/aio-libs/aiosmtpd/issues Git clone: https://github.com/aio-libs/aiosmtpd.git Documentation: http://aiosmtpd.readthedocs.io/ StackOverflow: https://stackoverflow.com/questions/tagged/aiosmtpd Cheers, -Barry
