by Martin Manns 29 Oct '10

29 Oct '10

Pyspread 0.1.2 released ======================= I am pleased to announce the new release 0.1.2 of pyspread. About: ------ Pyspread is a cross-platform Python spreadsheet application. It is based on and written in the programming language Python. Instead of spreadsheet formulas, Python expressions are entered into the spreadsheet cells. Each expression returns a Python object that can be accessed from other cells. These objects can represent anything including lists or matrices. Pyspread runs on Linux and *nix platforms with GTK support as well as on Windows (XP and Vista tested). On Mac OS X, some icons are too small but the application basically works. Homepage -------- http://pyspread.sourceforge.net Changes to 0.1.1 ---------------- New features: * Added function to make a cell visible * Third cell justification "center" added * Ctrl-F now points to find toolbar instead of find dialog * Frozen state is now saved * Entering text in a cell now deletes old text * Added function F5 (in menu View) for refreshing selected cells * Save option "pys file with/without gpg signature" added Bug fixes: * Grid flicker reduced * Printing works again * Changing the table now empties the entry line and does not mess up data any more (BUG 3030172) * 1D printing bug fixed (BUG 2790444) * Loading a file from command line no longer deletes cell 0,0,0 (BUG 3030880) * Undoing paste operations now works (BUG 3019334) * Bitmap toggle buttons now work in Windows as well * Marks undo and redo operation do not accumulate any more * Undoing text font and textattribute changes works now * CSV import dialog apply button removed * Cell limit (2**26) for 32 bit systems removed * Prints of off-screen areas now correctly center on page * Help now works when not in the home directory * Double underscores in Tutorial corrected * Pyspread gpg key name changed to pyspread_<user-id> * Deleting rows and columns can be undone again * When reversing search, all values are now found * Saved pys files now have .pys suffix added automatically * Fixed font size reset bug when setting font attributes * Loading a file from command line now checks signature correctly * Fixed moving cells bug for edits in non top-left grid position in wx.GTK Enjoy Martin

Pogo 0.2
by Jendrik Seipp 26 Oct '10

26 Oct '10

I am proud to announce the first release of Pogo, probably the simplest and fastest audio player for Linux. You can get the tarball and an Ubuntu deb package 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 0.2 "I hold the candle while you dance upon the flame" (2010-10-21) ==================================================================== * Make startup even faster by saving the playlist with its formatting * Make track drag'n'drop faster by caching the tracks * MPRIS support: Send DBus messages about play events (code from decibel) * Do some profiling to improve general speed * Append files added on commandline (pogo mytrack.mp3 myalbum myothertrack.mp3) * Append files added from nautilus right-click menu * Correctly add multiply nested directories * Activate the Covers and Notifications modules by default * Hide volume button (Only duplicates functionality of the Sound Indicator) * Updated Translations Cheers, Jendrik

libsndfile-python : python wrapper for libsndfile
by ./ed 25 Oct '10

25 Oct '10

Hi all, I am pleased to announce a release of a python wrapper for libsndfile. This is a re-installment of a previous version from Rob Melby (arcsin.org) with a numpy support. This a early beta release that worked fine for years using numpy and mostly intended for scientific applications. However I am not confident for non-macosx release. In addition libsndfile does not allow bundle building so the mpkg ships with its custom build of libsndfile. Consequently the source package should only works on Unixes. It is implied but libsndfile is needed : http://www.mega-nerd.com/libsndfile/ Please visit https://code.google.com/p/libsndfile-python/ for package information and https://code.google.com/p/libsndfile-python/downloads/list for available downloads. Help and feedback is really appreciated! Best, ./Ed

[ANN] ftputil 2.5 released
by Stefan Schwarzer 24 Oct '10

24 Oct '10

ftputil 2.5 is now available from http://ftputil.sschwarzer.net/download . Changes since version 2.4.2 --------------------------- - As announced over a year ago [1], the `xreadlines` method for FTP file objects has been removed, and exceptions can no longer be accessed via the `ftputil` namespace. Only use `ftp_error` to access the exceptions. The distribution contains a small tool `find_deprecated_code.py` to scan a directory tree for the deprecated uses. Invoke the program with the `--help` option to see a description. - Upload and download methods now accept a `callback` argument to do things during a transfer. Modification time comparisons in `upload_if_newer` and `download_if_newer` now consider the timestamp precision of the remote file which may lead to some unnecessary transfers. These can be avoided by waiting at least a minute between calls of `upload_if_newer` (or `download_if_newer`) for the same file. See the documentation for details [2]. - The `FTPHost` class got a `keep_alive` method. It should be used carefully though, not routinely. Please read the description [3] in the documentation. - Several bugs were fixed [4-7]. - The source code was restructured. The tests are now in a `test` subdirectory and are no longer part of the release archive. You can still get them via the source repository. Licensing matters have been moved to a common `LICENSE` file. 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. Read the documentation at http://ftputil.sschwarzer.net/documentation . License ------- ftputil is Open Source software, released under the revised BSD license (see http://www.opensource.org/licenses/bsd-license.php ).
