ANN: Lea 4.0.0 released
by pie.denis＠skynet.be Jan. 27, 2024

Jan. 27, 2024

Lea 4.0.0 is now released! --> https://pypi.org/project/lea/ Save the date: Live demo of Lea at FOSDEM'24, Brussels, Feb 4, 2024 (this is free!) --> https://fosdem.org/2024/schedule/track/python-devroom/ What is Lea? ----------------- Lea is a Python module for playing with discrete probability distributions in an intuitive way. This ranges from simple dice, coin flipping, random sampling . to Bayesian networks, Probabilistic Programming (PP), machine learning and symbolic computation. One salient feature of Lea is the ability to change the probability representation, viz. float, fractions, decimals, and symbols. Lea can be used for education, AI, PP, etc. Comprehensive tutorials are available online (see Wiki pages). For a 5 minutes tour, check out the poster presented at PROBPROG2020 conference: https://probprog.cc/2020/assets/posters/fri/69.pdf . What's new in Lea 4.0.0? --------------------------------- Here are the major changes since Lea 3.4.6: - optimization of conditional probabilities ('given' method), BN and fractions' display, - new "such_that" and "as_depending_on" methods to ease CPT creation (e.g. the Monty Hall problem) - persistent display options, including one line display of probability distributions, - fixes for mixing different probability representations, - indicators as method to call with parenthesis (e.g. x.mean() instead of x.mean), - extension of P, Pf, given_prob, is_any_of and is_none_of methods, - improved method documentation and code structure, - support to Python 3.8+ only (for Python 2.7+, you may still use Lea 3 --> https://pypi.org/project/lea/3.4.6/ ) For more information, you may check issues starting at #70 on https://bitbucket.org/piedenis/lea/issues . Acknowledgment ------------------------ Many, many thanks to Paul Moore, who has given the impetus for this new version! For several years, Paul has provided invaluable ideas, advice and contributions to the Lea project. To learn more... ---------------------- Lea on PyPI --> http://pypi.org/project/lea Lea project page --> http://bitbucket.org/piedenis/lea Documentation --> http://bitbucket.org/piedenis/lea/wiki/Home With the hope that Lea can make this universe less accidental, Pierre Denis

ANN: NumExpr 2.9.0 released
by Francesc Alted Jan. 26, 2024

Jan. 26, 2024

======================== Announcing NumExpr 2.9.0 ======================== Hi everyone, NumExpr 2.9.0 is a release offering support for latest versions of PyPy. The full test suite should pass now, at least for the Python 3.10 version. Thanks to @27rabbitlt for most of the work and @mgorny and @mattip for providing help and additional fixes. Project documentation is available at: http://numexpr.readthedocs.io/ Changes from 2.8.8 to 2.9.0 --------------------------- * Support for PyPy (see PRs #467 and #740). The full test suite should pass now, at least for the 3.10 version. Thanks to @27rabbitlt for most of the work and @mgorny and @mattip for providing help and additional fixes. Fixes #463. * Fixed more sanitizer issues (see PR #469). Thanks to @27rabbitlt. * Modernized the test suite to avoid some warnings. What's Numexpr? --------------- Numexpr is a fast numerical expression evaluator for NumPy. With it, expressions that operate on arrays (like "3*a+4*b") are accelerated and use less memory than doing the same calculation in Python. It has multi-threaded capabilities, as well as support for Intel's MKL (Math Kernel Library), which allows an extremely fast evaluation of transcendental functions (sin, cos, tan, exp, log...) while squeezing the last drop of performance out of your multi-core processors. Look here for a some benchmarks of numexpr using MKL: https://github.com/pydata/numexpr/wiki/NumexprMKL Its only dependency is NumPy (MKL is optional), so it works well as an easy-to-deploy, easy-to-use, computational engine for projects that don't want to adopt other solutions requiring more heavy dependencies. Where I can find Numexpr? ------------------------- The project is hosted at GitHub in: https://github.com/pydata/numexpr You can get the packages from PyPI as well (but not for RC releases): http://pypi.python.org/pypi/numexpr Documentation is hosted at: http://numexpr.readthedocs.io/en/latest/ Share your experience --------------------- Let us know of any bugs, suggestions, gripes, kudos, etc. you may have. Enjoy data!

mpdecimal-4.0.0 released
by Stefan Krah Jan. 25, 2024

Jan. 25, 2024

Hi, mpdecimal-4.0.0 has been released: https://www.bytereef.org/mpdecimal/changelog.html https://www.bytereef.org/mpdecimal/download.html The release has been tested on a compile farm for five months on the following platforms: x86_64, i386, aarch64, ppc64, ppc64le, chrp, sparc64, sparc32, mips64, mips32, risc-v, Wasm Tested compilers: gcc, clang, icc, icx, xlc, ibm-clang, cl.exe, clang-cl, mingw-gcc, CompCert, emscripten Distributors of CPython are strongly encouraged to build CPython --with-system-libmpdec (as most of them already do). Additionally, distributors of Python-11 and Python-12 are advised to revert the implementation of the z-format specifier in _decimal.c. It contains a memory leak for large decimals and does not support the "EG" types. mpdecimal-4.0.0 automatically supports the z-format specifier without patches to _decimal.c. The following patch cleanly reverts b0b836b20cb56c225874a4a39ef895f89ab2970f and applies to both Python-11 and Python-12: https://www.bytereef.org/contrib/0001-py12-revert-z-format-specifier.patch For the main branch, the following patches are advised: # As above: https://www.bytereef.org/contrib/0001-main-revert-z-format-specifier.patch # Implement a catch-all fallback for _all_ future format specifiers that # are _temporarily_ unsupported in mpdecimal. The fallback is clean and # is zero-cost for the general common case: https://www.bytereef.org/contrib/0002-main-fallback-to-pydecimal-format.pat… # Fix a deprecation warning that is incorrectly triggered for a fill # character that contains 'N': https://www.bytereef.org/contrib/0003-main-fix-deprecation-warning.patch All patches are "BSD-2-clause, Copyright (c) Stefan Krah", same as mpdecimal and Modules/_decimal/*. Finally, due to the nature of multiphase initialization, its current implementation in the main branch slows down the pi benchmark compared to 3.9 by: --enable-gil: 31% --disable-gil: 47% Stefan Krah

ANN: eGenix Antispam Bot for Telegram 0.6.0
by eGenix Team Jan. 24, 2024

Jan. 24, 2024

*ANNOUNCING* eGenix Antispam Bot for Telegram Version 0.6.0 A simple, yet effective bot implementation to address Telegram signup spam. This announcement is also available on our web-site for online reading: https://www.egenix.com/company/news/eGenix-Antispam-Bot-for-Telegram-0.6.0-… ------------------------------------------------------------------------ *INTRODUCTION* eGenix <https://egenix.com/> has long been running a local Python user group meeting in Düsseldorf called /Python Meeting Düsseldorf <https://pyddf.de/>/ and we are using a Telegram group for most of our communication. In the early days, the group worked well and we only had few spammers joining it, which we could well handle manually. More recently, this has changed dramatically. We are seeing between 2-5 spam signups per day, often at night. Furthermore, the signups accounts are not always easy to spot as spammers, since they often come with profile images, descriptions, etc. With the bot, we now have a more flexible way of dealing with the problem. Please see our project page for details and download links: https://www.egenix.com/library/telegram-antispam-bot/ ------------------------------------------------------------------------ *FEATURES* * Low impact mode of operation: the bot tries to keep noise in the group to a minimum * Several challenge mechanisms to choose from, more can be added as needed * Flexible and easy to use configuration * Only needs a few MB of RAM, so can easily be put into a container or run on a Raspberry Pi * Can handle quite a bit of load due to the async implementation * Works with Python 3.9+ * MIT open source licensed ------------------------------------------------------------------------ *NEWS* The 0.6.0 release fixes a few bugs and adds more features: * Upgraded to pyrogram 2.0.106, which fixes a weird error we have been getting recently with the old version 1.4.16 (see pyrogram/pyrogram#1347 <https://github.com/pyrogram/pyrogram/issues/1347>) * Catch weird error from Telegram when deleting conversations; this seems to sometimes fail, probably due to a glitch on their side * Made the math and char entry challenges a little harder * Added new DictItemChallenge It has been battle-tested in production for several years already already and is proving to be a really useful tool to help with Telegram group administration.

PyCA cryptography 42.0.0 released
by Paul Kehrer Jan. 22, 2024

Jan. 22, 2024

PyCA cryptography 42.0.0 has been released to PyPI. cryptography includes both high level recipes and low level interfaces to common cryptographic algorithms such as symmetric ciphers, asymmetric algorithms, message digests, X509, key derivation functions, and much more. We support Python 3.7+, and PyPy3 7.3.10+. Changelog (https://cryptography.io/en/latest/changelog/#v42-0-0): * BACKWARDS INCOMPATIBLE: Dropped support for LibreSSL < 3.7. * BACKWARDS INCOMPATIBLE: Loading a PKCS7 with no content field using load_pem_pkcs7_certificates() or load_der_pkcs7_certificates() will now raise a ValueError rather than return an empty list. * Parsing SSH certificates no longer permits malformed critical options with values, as documented in the 41.0.2 release notes. * Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.2.0. * Updated the minimum supported Rust version (MSRV) to 1.63.0, from 1.56.0. * We now publish both py37 and py39 abi3 wheels. This should resolve some errors relating to initializing a module multiple times per process. * Support PSS for X.509 certificate signing requests and certificate revocation lists with the keyword-only argument rsa_padding on the sign methods for CertificateSigningRequestBuilder and CertificateRevocationListBuilder. * Added support for obtaining X.509 certificate signing request signature algorithm parameters (including PSS) via signature_algorithm_parameters(). * Added support for obtaining X.509 certificate revocation list signature algorithm parameters (including PSS) via signature_algorithm_parameters(). * Added mgf property to PSS. * Added algorithm and mgf properties to OAEP. * Added the following properties that return timezone-aware datetime objects: not_valid_before_utc(), not_valid_after_utc(), revocation_date_utc(), next_update_utc(), last_update_utc(). These are timezone-aware variants of existing properties that return naïve datetime objects. * Deprecated the following properties that return naïve datetime objects: not_valid_before(), not_valid_after(), revocation_date(), next_update(), last_update() in favor of the new timezone-aware variants mentioned above. * Added support for ChaCha20 on LibreSSL. * Added support for RSA PSS signatures in PKCS7 with add_signer(). * In the next release (43.0.0) of cryptography, loading an X.509 certificate with a negative serial number will raise an exception. This has been deprecated since 36.0.0. * Added support for AESGCMSIV when using OpenSSL 3.2.0+. * Added the X.509 path validation APIs for Certificate chains. These APIs should be considered unstable and not subject to our stability guarantees until documented as such in a future release. * Added support for SM4 GCM when using OpenSSL 3.0 or greater. -Paul Kehrer (reaperhulk)
