Advanced Scientific Programming in Python ========================================= a Summer School by the G-Node, and the Centre for Integrative Neuroscience and Neurodynamics, School of Psychology and Clinical Language Sciences, University of Reading, UK Scientists spend more and more time writing, maintaining, and debugging software. While techniques for doing this efficiently have evolved, only few scientists have been trained to use them. As a result, instead of doing their research, they spend far too much time writing deficient code and reinventing the wheel. In this course we will present a selection of advanced programming techniques and best practices which are standard in the industry, but especially tailored to the needs of a programming scientist. Lectures are devised to be interactive and to give the students enough time to acquire direct hands-on experience with the materials. Students will work in pairs throughout the school and will team up to practice the newly learned skills in a real programming project — an entertaining computer game. We use the Python programming language for the entire course. Python works as a simple programming language for beginners, but more importantly, it also works great in scientific simulations and data analysis. We show how clean language design, ease of extensibility, and the great wealth of open source libraries for scientific computing and data visualization are driving Python to become a standard tool for the programming scientist. This school is targeted at Master or PhD students and Post-docs from all areas of science. Competence in Python or in another language such as Java, C/C++, MATLAB, or Mathematica is absolutely required. Basic knowledge of Python and of a version control system such as git, subversion, mercurial, or bazaar is assumed. Participants without any prior experience with Python and/or git should work through the proposed introductory material before the course. We are striving hard to get a pool of students which is international and gender-balanced. You can apply online: https://python.g-node.org Application deadline: 23:59 UTC, May 15, 2016. Be sure to read the FAQ before applying. Participation is for free, i.e. no fee is charged! Participants however should take care of travel, living, and accommodation expenses by themselves. Travel grants may be available. Date & Location =============== September 5—11, 2016.

qutebrowser v0.6.0 released!
by Florian Bruhin 05 Apr '16

05 Apr '16

Hi, I'm happy to annouce the release of qutebrowser v0.6.0! qutebrowser is a vim-like browser with a minimal user interface, based on Qt and Python: http://www.qutebrowser.org/ This release comes with dozens of bugfixes and various new features - the most notable one probably being a :buffers command with completion. Talking about completion, it now completes everything e.g. containing "github" and "qutebrowser" when doing ":open github qutebrowser" which makes it much easier to find pages in the history. sidenote: If you haven't seen it yet, qutebrowser's crowdfunding for the QtWebEngine backend is still running: http://igg.me/at/qutebrowser The full changelog: Added ~~~~~ - New `:buffer` command to easily switch tabs by name. This is not bound to a key by default for existing users due to a conflict with the `gt`/`gT` bindings (which are now removed from the default bindings). You can bind it by hand by running `:bind -f gt set-cmd-text -s :buffer`. - New `--quiet` argument for the `:debug-pyeval` command to not open a tab with the results. Note `:debug-pyeval` is still only intended for debugging. - The completion now matches each entered word separately. - A new command `:paste-primary` got added to paste the primary selection, and `<Shift-Insert>` got added as a binding so it pastes primary rather than clipboard. - New mode `word` for `hints -> mode` which uses a dictionary and link-texts for hints instead of single characters. - New `--all` argument for `:download-cancel` to cancel all running downloads. - New `password_fill` userscript to fill passwords using the `pass` executable. - New `current` hinting mode which forces opening hints in the current tab (even with `target="_blank"`) Changed ~~~~~~~ - Pasting multiple lines via `:paste` now opens each line in a new tab. - `:navigate increment/decrement` now preserves leading zeroes in URLs. - `general -> editor` can now also handle `{}` inside another argument (e.g. to open `vim` via `termite`) - Improved performance when scrolling with many tabs open. - Shift-Insert now also pastes primary selection for prompts. - `:download-remove --all` got un-deprecated to provide symmetry with `:download-cancel --all`. It does the same as `:download-clear`. - Improved detection of URLs/search terms when pasting multiple lines. - Don't remove `qutebrowser-editor-*` temporary file if editor subprocess crashed - Userscripts are also searched in `/usr/share/qutebrowser/userscripts`. - Blocked hosts are now also read from a `blocked-hosts` file in the config dir (e.g. `~/.config/qutebrowser/blocked-hosts`). Fixed ~~~~~ - Fixed starting with -c "". - Fixed crash when a tab is closed twice via javascript (e.g. Dropbox authentication dialogs) - Fixed crash when a notification/geolocation prompt is answered after closing the tab it belongs to. - Fixed crash when downloading a file without any path information (e.g a magnet link). - Fixed crashes when opening an empty URL (e.g. via pasting). - Fixed validation of duplicate values in `hints -> chars`. - Fixed crash when PDF.js was partially installed. - Fixed crash when XDG_DOWNLOAD_DIR was not an absolute path. - Fixed very long filenames when downloading `data://`-URLs. - Fixed ugly UI fonts on Windows when Liberation Mono is installed - Fixed crash when unbinding key from a section which doesn't exist in the config - Fixed report window after a segfault - Fixed some directory browser issues on Windows - Fixed crash when closing a window with a finished download and delayed `remove-finished-downloads` setting. - Fixed crash when hitting `<Tab>` then `<Ctrl-C>` on pages without keyboard focus. - Fixed "Frame load interrupted by policy change" error showing up when downloading files with Qt 5.6. Removed ~~~~~~~ - The `gt`/`gT` bindings (luakit-like alternatives to `J`/`K`) were removed (except for existing configs) to make room for the `gt` binding to show buffers. Since v0.5.0, the following people have contributed to qutebrowser: - Daniel Schadt - Felix Van der Jeugt - Tarcisio Fedrizzi - Philipp Hansch - Kevin Velghe - avk - Milan Svoboda - Clayton Craft - Oliver Caldwell - Thorsten Wißmann - Jakub Klinkovský - Patric Schmitz - Michael Ilsaas - Jimmy - Link - Ryan Roden-Corrent - Marcelo Santos - issue - haxwithaxe - evan - Tomasz Kramkowski - Tomas Orsava - Tobias Werth - Stefan Tatschner - Sorokin Alexei - Alexander Cogneau Thank you!

Twisted 16.1 Release Announcement
by Amber "Hawkie" Brown 04 Apr '16

04 Apr '16

On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 16.1! This release is hot off the heels of 16.0 released last month, including some nice little tidbits. The highlights include: - twisted.application.internet.ClientService, a service that maintains a persistent outgoing endpoint-based connection -- a replacement for ReconnectingClientFactory that uses modern APIs; - A large (77% on one benchmark) performance improvement when using twisted.web's client on PyPy; - A few conch modules have been ported to Python 3, in preparation for further porting of the SSH functionality; - Full support for OpenSSL 1.0.2f and above; - t.web.http.Request.addCookie now accepts Unicode and bytes keys/values; - `twistd manhole` no longer uses a hard-coded SSH host key, and will generate one for you on the fly (this adds a 'appdirs' PyPI dependency, installing with [conch] will add it automatically); - Over eighteen tickets overall closed since 16.0. For more information, check the NEWS file (link provided below). You can find the downloads at <https://pypi.python.org/pypi/Twisted> (or alternatively <http://twistedmatrix.com/trac/wiki/Downloads>). The NEWS file is also available at <https://github.com/twisted/twisted/blob/twisted-16.1.0/NEWS>. Many thanks to everyone who had a part in this release - the supporters of the Twisted Software Foundation, the developers who contributed code as well as documentation, and all the people building great things with Twisted! Twisted Regards, Amber Brown (HawkOwl)
