[RELEASED] Python 3.4.5rc1 and Python 3.5.2rc1 are now available
by Larry Hastings 12 Jun '16

12 Jun '16

On behalf of the Python development community and the Python 3.4 and Python 3.5 release teams, I'm pleased to announce the availability of Python 3.4.5rc1 and Python 3.5.2rc1. Python 3.4 is now in "security fixes only" mode. This is the final stage of support for Python 3.4. All changes made to Python 3.4 since Python 3.4.4 should be security fixes only; conventional bug fixes are not accepted. Also, Python 3.4.5rc1 and all future releases of Python 3.4 will only be released as source code--no official binary installers will be produced. Python 3.5 is still in active "bug fix" mode. Python 3.5.2rc1 contains many incremental improvements over Python 3.5.1. Both these releases are "release candidates". They should not be considered the final releases, although the final releases should contain only minor differences. Python users are encouraged to test with these releases and report any problems they encounter. You can find Python 3.4.5rc1 here: https://www.python.org/downloads/release/python-345rc1/ And you can find Python 3.5.2rc1 here: https://www.python.org/downloads/release/python-352rc1/ Python 3.4.5 final and Python 3.5.2 final are both scheduled for release on June 26th, 2016. Happy Pythoneering, //arry/

ANN: bcolz 1.1.0 released!
by Francesc Alted 10 Jun '16

10 Jun '16

====================== Announcing bcolz 1.1.0 ====================== What's new ========== This release brings quite a lot of changes. After format stabilization in 1.0, the focus is now in fine-tune many operations (specially queries in ctables), as well as widening the available computational engines. Highlights: * Much improved performance of ctable.where() and ctable.whereblocks(). Now bcolz is getting closer than ever to fundamental memory limits during queries (see the updated benchmarks in the data containers tutorial below). * Better support for Dask; i.e. GIL is released during Blosc operation when bcolz is called from a multithreaded app (like Dask). Also, Dask can be used as another virtual machine for evaluating expressions (so now it is possible to use it during queries too). * New ctable.fetchwhere() method for getting the rows fulfilling some condition in one go. * New quantize filter for allowing lossy compression of floating point data. * It is possible to create ctables with more than 255 columns now. Thanks to Skipper Seabold. * The defaults during carray creation are scalars now. That allows to create highly dimensional data containers more efficiently. * carray object does implement the __array__() special method now. With this, interoperability with numpy arrays is easier and faster. For a more detailed change log, see: https://github.com/Blosc/bcolz/blob/master/RELEASE_NOTES.rst For some comparison between bcolz and other compressed data containers, see: https://github.com/FrancescAlted/DataContainersTutorials specially chapters 3 (in-memory containers) and 4 (on-disk containers). What it is ========== *bcolz* provides columnar and compressed data containers that can live either on-disk or in-memory. Column storage allows for efficiently querying tables with a large number of columns. It also allows for cheap addition and removal of column. In addition, bcolz objects are compressed by default for reducing memory/disk I/O needs. The compression process is carried out internally by Blosc, an extremely fast meta-compressor that is optimized for binary data. Lastly, high-performance iterators (like ``iter()``, ``where()``) for querying the objects are provided. bcolz can use numexpr internally so as to accelerate many vector and query operations (although it can use pure NumPy for doing so too). numexpr optimizes the memory usage and use several cores for doing the computations, so it is blazing fast. Moreover, since the carray/ctable containers can be disk-based, and it is possible to use them for seamlessly performing out-of-memory computations. bcolz has minimal dependencies (NumPy), comes with an exhaustive test suite and fully supports both 32-bit and 64-bit platforms. Also, it is typically tested on both UNIX and Windows operating systems. Together, bcolz and the Blosc compressor, are finally fulfilling the promise of accelerating memory I/O, at least for some real scenarios: http://nbviewer.ipython.org/github/Blosc/movielens-bench/blob/master/queryi… Example users of bcolz are Visualfabriq (http://www.visualfabriq.com/), and Quantopian (https://www.quantopian.com/): * Visualfabriq: * *bquery*, A query and aggregation framework for Bcolz: * https://github.com/visualfabriq/bquery * Quantopian: * Using compressed data containers for faster backtesting at scale: * https://quantopian.github.io/talks/NeedForSpeed/slides.html Resources ========= Visit the main bcolz site repository at: http://github.com/Blosc/bcolz Manual: http://bcolz.blosc.org Home of Blosc compressor: http://blosc.org User's mail list: bcolz(a)googlegroups.com http://groups.google.com/group/bcolz License is the new BSD: https://github.com/Blosc/bcolz/blob/master/LICENSES/BCOLZ.txt Release notes can be found in the Git repository: https://github.com/Blosc/bcolz/blob/master/RELEASE_NOTES.rst ---- **Enjoy data!** -- Francesc Alted

qutebrowser v0.7.0 released!
by Florian Bruhin 10 Jun '16

10 Jun '16

Hi, I'm happy to annouce the release of qutebrowser v0.7.0! qutebrowser is a keyboard driven browser with a vim-like, minimalistic interface. It's written using PyQt and cross-platform. As usual the source release is available, binary releases (Windows as usual, and now also a standalone OS X .app/.dmg and a Debian .deb) will follow ASAP (but might be Monday until everything is taken care of). This is a really exciting release! It comes with fixes for a few long-standing bugs (like being able to use :hint spawn with flags or sharing of cookies between tabs with private browsing) and includes many new features (like marks to remember the scroll position). It also comes with a greatly improved hint and history implementation: Hints now work more reliably in some corner cases, and gained a few new features and other bugfixes. The history completion now contains titles and handles redirects. And there's a lot more than that - see the full changelog: Added ~~~~~ - New `:edit-url` command to edit the URL in an external editor. - New `network -> custom-headers` setting to send custom headers with every request. - New `{url:pretty}` commandline replacement which gets replaced by the decoded URL. - New marks to remember a scroll position: - New `:jump-mark` command to jump to a mark, bound to `'` - New `:set-mark` command to set a mark, bound to ```(backtick) - The `'` mark gets set when moving away (hinting link with anchor, searching, etc.) so you can move back with `''` - New `--force-color` argument to force colored logging even if stdout is not a terminal - New `:messages` command to show error messages - New pop-up showing possible keybinding when the first key of a keychain is pressed. This can be turned off using `:set ui keyhint-blacklist *`. - New `hints -> auto-follow-timeout` setting to ignore keypresses after following a hint when filtering in number mode. - New `:history-clear` command to clear the entire history - New `hints -> find-implementation` to select which implementation (JS/Python) should be used to find hints on a page. The `javascript` implementation is better, but slower. Changed ~~~~~~~ - qutebrowser got a new (slightly updated) logo - `:tab-focus` can now take a negative index to focus the nth tab counted from the right. - `:yank` can now yank the pretty/decoded URL by adding `--pretty` - `:navigate` now clears the URL fragment - `:completion-item-del` (`Ctrl-D`) can now be used in `:buffer` completion to close a tab - Counts can now be used with special keybindings (e.g. with modifiers) - Various SSL ciphers are now disabled by default. With recent Qt/OpenSSL versions those already all are disabled, but with older versions they might not be. - Show favicons as window icon with `tabs-are-windows` set. - `:bind <key>` without a command now shows the existing binding - The optional `colorlog` dependency got removed, as qutebrowser now displays colored logs without it. - URLs are now shown decoded when hovering. - Keybindings are now shown in the command completion - Improved behavior when pasting multiple lines - Rapid hints can now also be used for the `normal` hint target, which can be useful with javascript click handlers or checkboxes which don't actually open a new page. - `:zoom-in` or `:zoom-out` (`+`/`-`) with a too large count now zooms to the smallest/largest zoom instead of doing nothing. - The commandline now accepts partially typed commands if they're unique. - Number hints are now kept filtered after following a hint in rapid mode. - Number hints are now renumbered after filtering - Number hints can now be filtered with multiple space-separated search terms - `hints -> scatter` is now ignored for number hints - Better history implementation which also stores titles. As a consequence, URLs which redirect to another URL are now added to the history too, marked with a `-r` suffix to the timestamp field. Fixed ----- - Fixed using `:hint links spawn` with flags - you can now use things like the `-v` argument for `:spawn` or pass flags to the spawned commands. - Various fixes for hinting corner-cases where following a link didn't work or the hint was drawn at the wrong position. - Fixed crash when downloading from an URL with SSL errors - Close file handles correctly when a download failed - Fixed crash when using `;Y` (`:hint links yank-primary`) on a system without primary selection - Don't display quit confirmation with finished downloads - Fixed updating the tab index in the statusbar when opening a background tab - Fixed a crash when entering `:-- ` in the commandline - Fixed `:debug-console` with PyQt 5.6 - Fixed qutebrowser not starting when `sys.stderr` is `None` - Fixed crash when cancelling a download which belongs to a MHTML download - Fixed rebinding of keybindings being case-sensitive - Fix for tab indicators getting lost when moving tabs - Fixed handling of backspace in number hinting mode - Fixed `FileNotFoundError` when starting in some cases on old Qt versions - Fixed sharing of cookies between tabs when `private-browsing` is enabled - Toggling values with `:set` now uses lower-case values - Hints now work with (non-standard) links with spaces around the URL - Strip off trailing spaces for history entries with no title Since v0.6.0, the following people have contributed to qutebrowser: - Ryan Roden-Corrent - Daniel Schadt - Jakub Klinkovský - Panagiotis Ktistakis - Corentin Julé - Felix Van der Jeugt - Tarcisio Fedrizzi - Liam BEGUIN - Jimmy - kanikaa1234 - Tomasz Kramkowski - Philipp Hansch - Nick Ginther - Fritz Reichwald - haitaka - Ismail - adam - Stefan Tatschner - Samuel Loury - Jan Verbeek - oniondreams - Xitian9 - Noah Huesser - Johannes Martinsson - Jay Kamat - Error 800 - Alexey Glushko Thank you!
