luban 1.0.1 released
by Jiao Lin 15 Jan '12

15 Jan '12

Luban 1.0.1 was released. In this release, "Workflow" was introduced to make it easier for users to build their applications using workflows as building blocks. A tutorial of "workflow" is here: http://lubanui.org/current/workflow-tutorial.html. The first three workflows introduced were: registration, login, and feedback; see http://lubanui.org/current/workflow.html. These workflow examples also show how luban could work with models and database. Once luban is installed, you can read its source code to find out how those workflows were implemented to work with database models. They are under luban python sub-packages "luban.workflows.<workflow>". Or you can find source code of workflows here: http://bazaar.launchpad.net/~jiao-lin/luban/trunk/files/head:/workflows/lub…. Please keep in mind, however, luban is not intended to be a full-featured python web framework. Its main purpose is to help (web) UI developers to specify their UI applications in a generic and concise way. So these workflows are just examples, and are not the main functionality of luban. They can be used as scaffolding tools for your applications, but in no way they should limit you from finding creative ways of using luban with stuff typically found in a python web framework -- database, orm, etc. There are some new developments for the luban API documentation and demo, "aokuang" (http://lubanui.org/aokuang) as well. API/demo for individual widget is now available at http://aokuang.lubanui.org/<widget>. For example, http://aokuang.lubanui.org/document. Also, you could get a sneak peak at one new widget for the next release, luban 1.0.2, "sketchcanvas", at http://aokuang.lubanui.org/sketchcanvas. ------- Luban (http://lubanui.org) is a compact, generic UI "language". It is a python package for building (web) user interface. It is NOT yet-another web framework. Features: * Dynamic, ajax-based web user interface can be created using pure python (no knowledge of javascript/ajax/etc is required) * A compact set of simple concepts and rules * Simple, natural syntax for describing UI * A set of basic and advanced widgets --- see demo and API of widgets at http://lubanui.org/aokuang * Write "bindings" of your favorite js widgets to use them in python. Python versions: * Luban 1.0.1 mainly supports python 3.1+ * Experimental support for python 2.6+ exists. Installation: $ pip install luban Bug reports and any comments are appreciated! -- Jiao Lin linjiao(a)caltech.edu

Qdb: a small & simple remote client/server debugger, released
by Mariano Reingart 14 Jan '12

14 Jan '12

FYI Just released Qdb, a small & simple remote client/server debugger based on Bdb (Pdb style), wich could be used from a remote terminal to any server (and in the near future, with a nice visual IDE): http://code.google.com/p/rad2py/wiki/QdbRemotePythonDebugger It uses multiprocessing.connection to communicate between the backend and frontend, with a simple JSONRPC-like stream protocol. It could use also Queues or Pipes for communication, and includes a basic frontend (Cmd command line based) that can be replaced with a visual interface (currently working on a wxPython one, but it could be adapted to any framework/toolkit) Quick start guide: 1. Download qdb.py (put in your python path / local folder) 2. Add the following line: import qdb; qdb.set_trace() 3. In a terminal, run: python qdb.py Then run the main program, when the qdb.set_trace() line is reached, you'll see the debugger prompt in your terminal. Also, it can invoke a program to be debugged using pdb like syntax: python -m qdb yourscript.py To connect to a remote server, just change addres and password in the source file. ASAP that will be more configurable. This work was started as a research thesis, but I think it can be used for other purposes too. Comments and contributions are welcome ;-) Best regards Mariano Reingart http://www.sistemasagiles.com.ar http://reingart.blogspot.com

ANN: pysendfile 0.2.0 released
by Giampaolo Rodolà 13 Jan '12

13 Jan '12

Hi folks, I'm pleased to announce the 0.2.0 release of pysendfile: http://code.google.com/p/pysendfile === About === This is a python interface to sendfile(2) system call available on most UNIX systems. sendfile(2) provides a "zero-copy" way of copying data from one file descriptor to another (a socket). The phrase "zero-copy" refers to the fact that all of the copying of data between the two descriptors is done entirely by the kernel, with no copying of data into userspace buffers, resuting in file transfers being from 2x to 3x faster. Basically, any application sending files over the network can take advantage of it. HTTP and FTP servers are a typical example. === Supported platforms === * Linux * Mac OSX * FreeBSD * Dragon Fly BSD * Sun OS * AIX (not properly tested) === Supported python versions === >From 2.5 to 3.3. === Links === * Home page: http://code.google.com/p/pysendfile * Source tarball: http://pysendfile.googlecode.com/files/pysendfile-0.2.0.tar.gz --- Giampaolo Rodola' http://code.google.com/p/pyftpdlib/ http://code.google.com/p/psutil/ http://code.google.com/p/pysendfile/

Pogo 0.5
by Jendrik Seipp 12 Jan '12

12 Jan '12

I am proud to announce the release of Pogo, probably the simplest and fastest audio player for Linux. The tarball and an Ubuntu PPA are available at http://launchpad.net/pogo What is Pogo? -------------------- Pogo plays your music. Nothing else. It tries to be fast and easy-to-use. Pogo's elementary-inspired design uses the screen-space very efficiently. It is especially well-suited for people who organize their music by albums on the harddrive. The main interface components are a directory tree and a playlist that groups albums in an innovative way. Pogo is a fork of Decibel Audio Player. Supported file formats include Ogg Vorbis, MP3, FLAC, Musepack, Wavpack, and MPEG-4 AAC. Pogo is written in Python and uses GTK+ and gstreamer. What's new in 0.5 "Rolling in the deep" (2012-01-12) ======================================= * Export tracks in playlist into a directory (with subdirectories) * Save playlist periodically to prevent losing it during a shutdown (LP:669132) * Usability: Select new track when old selected is deleted * Fix: Playback after pause should show the play icon, not the pause icon * Fix: Never interrupt playing song when appending new ones (lp:735619) * Cache music folders repeatedly to speedup searches * Let user remove music folders that were deleted from the hard disk * Do not add music folders that have been deleted * Apply fix from decibel: Skipping track just before the end skips the following track * Apply fix from decibel: Sort files case-independently * Apply fix from decibel: Raise the window of the already running instance if there is one * Apply fix from decibel: Create symbolic links to covers so that external apps can access them * Log all messages to log file * Updated translations Cheers, Jendrik

pytickets 0.9.0 - light-weight cryptographically signed data containers
by Krister Hedfors 12 Jan '12

12 Jan '12

pytickets are light-weight symmetrically signed data containers with optional encryption, serialization and compression of their contents. A sample anti-XSRF-library (tickets.web.forms.FormTokenService) based on pytickets is included. It's stateless (as tickets are stand-alone signed containers) and provides more security options than most anti- XSRF-libraries in use today, for instance only allowing pre-declared parameter names to be submitted. http://pypi.python.org/pypi/pytickets/0.9.0 Documentation: http://pytickets.tripleaes.com/
