Thespian 3.8.3 released
by Kevin Quick 09 Nov '17

09 Nov '17

Release 3.8.3 of Thespian is now available on pypi, with additional information at htttp://thespianpy.com including release notes, documentation, and repository references. ----- Thespian is a Python library providing a framework for developing concurrent, distributed, fault tolerant applications. Thespian is built on the Actor Model which allows applications to be written as a group of independently executing but cooperating "Actors" which communicate via messages. These Actors run within the Actor System provided by the Thespian library. Concurrent All Actors run independently within the Actor System. The Actor System may run the Actors as threads, processes, or even sequential operations within the current process—all with no change to the Actors themselves. Distributed Actors run independently…anywhere. Multiple servers can each be running Thespian and an Actor can be run on any of these systems—all with no change to the Actors themselves. Thespian handles the communication between the Actors and the management process of distributing the Actors across the systems. Location Independent Because Actors run independently anywhere, they run independently of their actual location. A distributed Actor application may have part of it running on a local server, part running on a server in Amsterdam, and part running on a server in Singapore… or not, with no change or awareness of this by the Actors themselves. Fault Tolerant Individual Actors can fail and be restarted—automatically—without impact to the rest of the system. Scalable The number of Actors in the system can be dynamically extended based on factors such as work volume, and systems added to the Distributed Actor System environment are automatically utilized. One of the key aspects of the Actor Model is that it represents a higher level of abstraction than is provided by most frameworks. When writing an Actor-based application, the concurrency and transport layers are completely abstracted, which both simplifies the design and allows the concurrency or transport to be changed in the future without requiring changes in the Actor-based application. The above qualities of Actor programming make it ideally suited for Cloud-based applications as well, where compute nodes are added and removed from the environment dynamically.

Hello all, I'm glad to announce the release of pyo 0.8.8, available for python 2.7, 3.5 and 3.6. Pyo is a Python module written in C to help real-time digital signal processing script creation. It is available for Windows, macOS and linux. It is released under the LGPL 3 license. For more info, downloads and other links, see the official web site: http://ajaxsoundstudio.com/software/pyo/ The documentation: http://ajaxsoundstudio.com/pyodoc/ For the latest sources and bug tracker: https://github.com/belangeo/pyo Bug Fixes: - Added missing binding to stop method in MidiListener. - Removed internal import of the random module. Scripts importing both pyo and random modules segfault on garbage collection at exit. - Added missing static declaration to functions in pyomodule. - E-Pyo: Fixed startup crash when preferences contains unicode characters. - Granulator now compensates for the difference between the loaded sound's sampling rate and pyo's sampling rate, if any. - Fixed PyoArgumentTypeError when ctrl() is called for an object with dataOnly parameter and tk is used instead of wxpython. - Don't try to deactivate jack if it is stopped externally (ex. from qjackctl). - Fixed audio and midi backends memory allocation. - Properly incref and decref server references inside pyo objects. - Fixed path encoding on windows for python 3.6. Enhancements: - Added Jack midi support to the Server. - Added a new init argument (wintitle) to Scope and Spectrum objects to allow the user to set the title name of their windows. Also added a method to show/hide the channel labels in the GUI. - Added a callback attribute to PVAnal. The function receives magnitudes and true frequencies for every analysis frame.

attrs 17.3.0 released!
by Hynek Schlawack 08 Nov '17

08 Nov '17

Hi everyone, I’m very excited to announce the 17.3.0 release of attrs <http://www.attrs.org/>, the package that will make you love writing classes again! A lot has happened under the hood but the main feature we’d like to point out is first-class support for types including PEP 526-style class variable annotations: ```pycon >>> @attr.s ... class C: ... x = attr.ib(type=int) ... y: int = attr.ib() >>> attr.fields(C).x.type <class 'int'> >>> attr.fields(C).y.type <class 'int'> ``` And if you’re OK with annotating *all* attributes, you can drop the `attr.ib()` completely with the new `auto_attribs` option. Anything that is assigned to the attributes and isn’t an `attr.ib` is used as a default value: ```pycon >>> import typing >>> @attr.s(auto_attribs=True) ... class AutoC: ... cls_var: typing.ClassVar[int] = 5 # this one is ignored ... l: typing.List[int] = attr.Factory(list) ... x: int = 1 ... bar: typing.Any = None >>> AutoC() AutoC(l=[], x=1, bar=None) ``` Please note: - This feature works with Python 3.6 and later only. - The type information is currently *not* used by attrs itself, but it allows you to write advanced validators and serializers. Check out the changelog for all changes: <http://www.attrs.org/en/stable/changelog.html> Get it from PyPI: <https://pypi.org/project/attrs/> For the attrs team, Hynek Schlawack

ftputil 3.4 released
by Stefan Schwarzer 08 Nov '17

08 Nov '17

ftputil 3.4 is now available from http://ftputil.sschwarzer.net/download . Changes since version 3.3.1 --------------------------- - Several bugs were fixed [1-5]. - Added deprecation warnings for backward incompatibilities in the upcoming ftputil 4.0.0. Important note -------------- The next version of ftputil will be 4.0.0 (apart from small fixes in possible 3.4.x versions). ftputil 4.0.0 will make some backward-incompatible changes: - Support for Python 2 will be removed. There are several reasons for this, which are explained in [6]. - The flag `use_list_a_option` will be set to `False` by default. This option was intended to make life easier for users, but turned out to be problematic (see [7]). What is ftputil? ---------------- ftputil is a high-level FTP client library for the Python programming language. ftputil implements a virtual file system for accessing FTP servers, that is, it can generate file-like objects for remote files. The library supports many functions similar to those in the os, os.path and shutil modules. ftputil has convenience functions for conditional uploads and downloads, and handles FTP clients and servers in different timezones. See the documentation for details: http://ftputil.sschwarzer.net/trac/wiki/Documentation License ------- ftputil is open source software, released under the revised BSD license (see http://opensource.org/licenses/BSD-3-Clause ).
