GeoBases: data services and visualization, version 5
by geobases.dev＠gmail.com 08 Mar '13

08 Mar '13

Hello! We just released the version 5 (rc) of GeoBases! For those who do not know GeoBases, this project provides tools to play with geographical data. It also works with non-geographical data, except for map visualizations :). There are embedded data sources in the project, but you can easily play with your own data in addition to the available ones. After data loading, you can: - perform various types of queries (find this key, or find keys with this property) - make fuzzy searches based on string distance (find things roughly named like this) - make phonetic searches (find things sounding like this) - make geographical searches (find things next to this place) - get results on a map, or on a graph, or export it as csv data, or as a Python object A few highlights of this new version (more details on https://github.com/opentraveldata/geobases/wiki/News): - join clauses (tutorial https://github.com/opentraveldata/geobases/wiki/Join-clauses-tutorial) - admin mode (tutorial https://github.com/opentraveldata/geobases/wiki/Admin-mode-tutorial) - learning mode - sub-indexes - phonetic search - graph display - better zsh autocomplete We tried to improve the documentation with: - a wiki containing quickstart and tutorials - a Twitter account to answer questions - the API documentation on readthedocs. Get the code from Github https://github.com/opentraveldata/geobases Useful links: Wiki : https://github.com/opentraveldata/geobases/wiki/_pages API doc : https://geobases.readthedocs.org Twitter : https://twitter.com/GeoBasesDev/ Site : http://opentraveldata.github.com/geobases/ If you like it, share it!

Hi, Wyplay is proud to announce the release of a new tool to track Python memory allocations: "pytracemalloc". https://pypi.python.org/pypi/pytracemalloc https://github.com/wyplay/pytracemalloc pytracemalloc provides the following information: - Allocated size and number of allocations per file, or optionally per file and line number - Compute the average size of memory allocations - Compute delta between two "snapshots" - Get the source of a memory allocation: filename and line number It helps to track memory leaks: show directly in which Python files the memory increases. Example of pytracemalloc output (compact): 2013-02-28 23:40:18: Top 5 allocations per file #1: .../Lib/test/regrtest.py: 3998 KB #2: .../Lib/unittest/case.py: 2343 KB #3: .../ctypes/test/__init__.py: 513 KB #4: .../Lib/encodings/__init__.py: 525 KB #5: .../Lib/compiler/transformer.py: 438 KB other: 32119 KB Total allocated size: 39939 KB Example of pytracemalloc output (full): 2013-03-04 01:01:55: Top 10 allocations per file and line #1: .../2.7/Lib/linecache.py:128: size=408 KiB (+408 KiB), count=5379 (+5379), average=77 B #2: .../unittest/test/__init__.py:14: size=401 KiB (+401 KiB), count=6668 (+6668), average=61 B #3: .../2.7/Lib/doctest.py:506: size=319 KiB (+319 KiB), count=197 (+197), average=1 KiB #4: .../Lib/test/regrtest.py:918: size=429 KiB (+301 KiB), count=5806 (+3633), average=75 B #5: .../Lib/unittest/case.py:332: size=162 KiB (+136 KiB), count=452 (+380), average=367 B #6: .../Lib/test/test_doctest.py:8: size=105 KiB (+105 KiB), count=1125 (+1125), average=96 B #7: .../Lib/unittest/main.py:163: size=77 KiB (+77 KiB), count=1149 (+1149), average=69 B #8: .../Lib/test/test_types.py:7: size=75 KiB (+75 KiB), count=1644 (+1644), average=46 B #9: .../2.7/Lib/doctest.py:99: size=64 KiB (+64 KiB), count=1000 (+1000), average=66 B #10: .../Lib/test/test_exceptions.py:6: size=56 KiB (+56 KiB), count=932 (+932), average=61 B 3023 more: size=1580 KiB (+1138 KiB), count=12635 (+7801), average=128 B Total: size=3682 KiB (+3086 KiB), count=36987 (+29908), average=101 B To install pytracemalloc, you need to patch and recompile your own version of Python to be able to hook all Python memory allocations. -- Wyplay was created in March 2006 in the south of France.

tox-1.4.3: quickstart command, "-l" option and fixes
by holger krekel 01 Mar '13

01 Mar '13

tox 1.4.3: the Python virtualenv-based testing automatizer ============================================================================= tox 1.4.3 fixes some bugs and introduces a new script and two new options: - "tox-quickstart" - run this script, answer a few questions, and get a tox.ini created for you (thanks Marc Abramowitz) - "tox -l" lists configured environment names (thanks Lukasz Balcerzak) - (experimental) "--installpkg=localpath" option which will skip the sdist-creation of a package and instead install the given localpath package. - use pip-script.py instead of pip.exe on win32 to avoid windows locking the .exe Note that the sister project "detox" should continue to work - it's a separately released project which drives tox test runs on multiple CPUs in parallel. More documentation: http://tox.testrun.org/ Installation: pip install -U tox repository hosting and issue tracking on bitbucket: https://bitbucket.org/hpk42/tox What is tox? ---------------- tox standardizes and automates tedious python driven test activities driven from a simple ``tox.ini`` file, including: * creation and management of different virtualenv environments with different Python interpreters * packaging and installing your package into each of them * running your test tool of choice, be it nose, py.test or unittest2 or other tools such as "sphinx" doc checks * testing dev packages against each other without needing to upload to PyPI best, Holger Krekel CHANGELOG ================ 1.4.3 (compared to 1.4.2) -------------------------------- - introduce -l|--listenv option to list configured environments (thanks Lukasz Balcerzak) - fix downloadcache determination to work according to docs: Only make pip use a download cache if PIP_DOWNLOAD_CACHE or a downloadcache=PATH testenv setting is present. (The ENV setting takes precedence) - fix issue84 - pypy on windows creates a bin not a scripts venv directory (thanks Lukasz Balcerzak) - experimentally introduce --installpkg=PATH option to install a package rather than create/install an sdist package. This will still require and use tox.ini and tests from the current working dir (and not from the remote package). - substitute {envsitepackagesdir} with the package installation directory (closes #72) (thanks g2p) - issue #70 remove PYTHONDONTWRITEBYTECODE workaround now that virtualenv behaves properly (thanks g2p) - merged tox-quickstart command, contributed by Marc Abramowitz, which generates a default tox.ini after asking a few questions - fix #48 - win32 detection of pypy and other interpreters that are on PATH (thanks Gustavo Picon) - fix grouping of index servers, it is now done by name instead of indexserver url, allowing to use it to separate dependencies into groups even if using the same default indexserver. - look for "tox.ini" files in parent dirs of current dir (closes #34) - the "py" environment now by default uses the current interpreter (sys.executable) make tox' own setup.py test execute tests with it (closes #46) - change tests to not rely on os.path.expanduser (closes #60), also make mock session return args[1:] for more precise checking (closes #61) thanks to Barry Warszaw for both.

WebElements - QT Inspired web development framework for python released
by timothy.crosley＠gmail.com 01 Mar '13

01 Mar '13

Hi Everyone, I've been working on a web development framework that integrates several popular QT features (such as a graphical template builder, signal / slots, ui's built by objects) for the last few years, and I was hoping that some people here might find it useful. If you are interested the main link for the widgets is http://www.webelements.in and the link for the framework overall is http://www.webbot.ws Thanks! Timothy
