by hans moleman 21 Apr '11

21 Apr '11

CodeInvestigator version 1.5.0 was released on April 21. Changes: - A lot of UI changes. Backgrounds, code blocks and menu. - Print statements can now be clicked. The entire printout shows and what was contributed by the print statement. - Browser collection of runtime data is faster: Clicking a different iteration for example, gives faster results. Bug fixes: - For Windows users: The command window needed to be visible again to stop it flashing up. - There were a few bugs in the searches. CodeInvestigator is a tracing tool for Python programs. Running a program through CodeInvestigator creates a recording. Program flow, function calls, variable values and conditions are all stored for every line the program executes. The recording is then viewed with an interface consisting of the code. The code can be clicked: A clicked variable displays its value, a clicked loop displays its iterations. You read code, and have at your disposal all the run time details of that code. A computerized desk check tool and another way to learn about your program. http://sourceforge.net/projects/cde-investigatr/files/

[ANN] guiqwt v2.1.1
by Pierre.RAYBAUT＠CEA.FR 20 Apr '11

20 Apr '11

Hi all, I am pleased to announce that `guiqwt` v2.1.1 has been released. Main changes since `guiqwt` v2.1.0: * added support for NaNs in image plot items (default behaviour: NaN pixels are transparents) * added "oblique averaged cross section" feature * bugfixes This version of `guiqwt` includes a demo software, Sift (for Signal and Image Filtering Tool), based on `guidata` and `guiqwt`: http://packages.python.org/guiqwt/sift.html Windows users may even download the portable version of Sift 0.23 to test it without having to install anything: http://code.google.com/p/guiqwt/downloads/detail?name=sift023_portable.zip The `guiqwt` documentation with examples, API reference, etc. is available here: http://packages.python.org/guiqwt/ Based on PyQwt (plotting widgets for PyQt4 graphical user interfaces) and on the scientific modules NumPy and SciPy, guiqwt is a Python library providing efficient 2D data-plotting features (curve/image visualization and related tools) for interactive computing and signal/image processing application development. When compared to the excellent module `matplotlib`, the main advantage of `guiqwt` is performance: see http://packages.python.org/guiqwt/overview.html#performances. But `guiqwt` is more than a plotting library; it also provides: * Helper functions for data processing: see the example http://packages.python.org/guiqwt/examples.html#curve-fitting * Framework for signal/image processing application development: see http://packages.python.org/guiqwt/examples.html * And many other features like making executable Windows programs easily (py2exe helpers): see http://packages.python.org/guiqwt/disthelpers.html guiqwt plotting features are the following: guiqwt.pyplot: equivalent to matplotlib's pyplot module (pylab) supported plot items: * curves, error bar curves and 1-D histograms * images (RGB images are not supported), images with non-linear x/y scales, images with specified pixel size (e.g. loaded from DICOM files), 2-D histograms, pseudo-color images (pcolor) * labels, curve plot legends * shapes: polygon, polylines, rectangle, circle, ellipse and segment * annotated shapes (shapes with labels showing position and dimensions): rectangle with center position and size, circle with center position and diameter, ellipse with center position and diameters (these items are very useful to measure things directly on displayed images) curves, images and shapes: * multiple object selection for moving objects or editing their properties through automatically generated dialog boxes (guidata) * item list panel: move objects from foreground to background, show/hide objects, remove objects, ... * customizable aspect ratio * a lot of ready-to-use tools: plot canvas export to image file, image snapshot, image rectangular filter, etc. curves: * interval selection tools with labels showing results of computing on selected area * curve fitting tool with automatic fit, manual fit with sliders, ... images: * contrast adjustment panel: select the LUT by moving a range selection object on the image levels histogram, eliminate outliers, ... * X-axis and Y-axis cross-sections: support for multiple images, average cross-section tool on a rectangular area, ... * apply any affine transform to displayed images in real-time (rotation, magnification, translation, horizontal/vertical flip, ...) application development helpers: * ready-to-use curve and image plot widgets and dialog boxes * load/save graphical objects (curves, images, shapes) * a lot of test scripts which demonstrate guiqwt features guiqwt has been successfully tested on GNU/Linux and Windows platforms. Python package index page: http://pypi.python.org/pypi/guiqwt/ Documentation, screenshots: http://packages.python.org/guiqwt/ Downloads (source + Python(x,y) plugin): http://guiqwt.googlecode.com Cheers, Pierre --- Dr. Pierre Raybaut CEA - Commissariat à l'Energie Atomique et aux Energies Alternatives

Extended deadline; IFIP sponsorship: IFIP Working Conference on Domain-Specific Languages
by Emilie Balland 20 Apr '11

20 Apr '11

IFIP Working Conference on Domain-Specific Languages (DSL) 6-8 September 2011, Bordeaux, France http://dsl2011.bordeaux.inria.fr/ CALL FOR PAPERS (EXTENDED DEADLINE; IFIP SPONSORSHIP) Domain-specific languages have long been a popular way to shorten the distance from ideas to products in software engineering. On one hand, the interface of a DSL lets domain experts express high-level concepts succinctly in familiar notation, such as grammars for text or scripts for animation, and often provides guarantees and tools that take advantage of the specifics of the domain to help write and maintain these particular programs. On the other hand, the implementation of a DSL can automate many tasks traditionally performed by a few experts to turn a specification into an executable, thus making this expertise available widely. Overall, a DSL thus mediates a collaboration between its users and implementers that results in software that is more usable, more portable, more reliable, and more understandable. These benefits of DSLs have been delivered in domains old and new, such as signal processing, data mining, and Web scripting. Widely known examples of DSLs include Matlab, Verilog, SQL, LINQ, HTML, OpenGL, Macromedia Director, Mathematica, Maple, AutoLisp/AutoCAD, XSLT, RPM, Make, lex/yacc, LaTeX, PostScript, and Excel. Despite these successes, the adoption of DSLs have been stunted by the lack of general tools and principles for developing, compiling, and verifying domain-specific programs. General support for building and using DSLs is thus urgently needed. Languages that straddle the line between the domain-specific and the general-purpose, such as Perl, Tcl/Tk, and JavaScript, suggest that such support be based on modern notions of language design and software engineering. The goal of this conference, following the last one in 2009, is to explore how present and future DSLs can fruitfully draw from and potentially enrich these notions. We seek research papers on the theory and practice of DSLs, including but not limited to the following topics. * Foundations, including semantics, formal methods, type theory, and complexity theory * Language design, including concrete syntax, semantics, and types * Software engineering, including domain analysis, software design, and round-trip engineering * Modularity and composability of DSLs * Software processes, including metrics for software and language evaluation * Implementation, including parsing, compiling, program generation, program analysis, transformation, optimization, and parallelization * Reverse engineering, re-engineering, design discovery, automated refactoring * Hardware/software codesign * Programming environments and tools, including visual languages, debuggers, testing, and verification * Teaching DSLs and the use of DSLs in teaching * Case studies in any domain, especially the general lessons they provide for DSL design and implementation The conference will include a visit to the city of Bordeaux, a tour and tasting at the wine museum and cellar, and a banquet at La Belle Époque. INSTRUCTIONS FOR AUTHORS Papers will be judged on the depth of their insight and the extent to which they translate specific experience into general lessons for software engineers and DSL designers and implementers. Where appropriate, papers should refer to actual languages, tools, and techniques, provide pointers to full definitions, proofs, and implementations, and include empirical results. Proceedings will be published in Electronic Proceedings in Theoretical Computer Science (http://info.eptcs.org/). Submissions and final manuscripts should be at most 25 pages in EPTCS format. IMPORTANT DATES * 2011-04-25: Abstracts due (extended deadline) * 2011-05-02: Submissions due (extended deadline) * 2011-06-10: Authors notified of decisions * 2011-07-11: Final manuscripts due * 2011-09-05: Distilled tutorials * 2011-09-06/2011-09-08: Main conference PROGRAM COMMITTEE * Emilie Balland (INRIA) * Olaf Chitil (University of Kent) * Zoé Drey (LaBRI) * Nate Foster (Cornell University) * Mayer Goldberg (Ben-Gurion University) * Shan Shan Huang (LogicBlox) * Sam Kamin (University of Illinois at Urbana-Champaign) * Jerzy Karczmarczuk (University of Caen) * Jan Midtgaard (Aarhus University) * Keiko Nakata (Tallinn University of Technology) * Klaus Ostermann (University of Marburg) * Jeremy Siek (University of Colorado at Boulder) * Tony Sloane (Macquarie University) * Josef Svenningsson (Chalmers University of Technology) * Paul Tarau (University of North Texas) * Dana N.

ANNOUNCE: wxPython 2.8.12.0
by Robin Dunn 19 Apr '11

19 Apr '11

Announcing ---------- The 2.8.12.0 release of wxPython is now available for download at http://wxpython.org/download.php. This release has no major new features or enhancements, but there have been plenty of bug fixes since the last stable release. Source code is available as a tarball, and binaries are also available for Python 2.6 and 2.7, for Windows and Mac, as well some packages for various Linux distributions in the wx apt repository. Binaries for Python 2.5 have been discontinued. What is wxPython? ----------------- wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a Python extension module that wraps the GUI components of the popular wxWidgets cross platform library, which is written in C++. wxPython is a cross-platform toolkit. This means that the same program will usually run on multiple platforms without modifications. Currently supported platforms are 32-bit and 64-bit Microsoft Windows, most Linux or other Unix-like systems using GTK2, and Mac OS X 10.4+. In most cases the native widgets are used on each platform to provide a 100% native look and feel for the application. -- Robin Dunn Software Craftsman http://wxPython.org
