For the human brain, sequences like -> , <= or := are single logical tokens, even if they take two or three characters on the screen. Your eye spends a non-zero amount of energy to scan, parse and join multiple characters into a single logical one. Ideally, all programming languages should be designed with full-fledged Unicode symbols for operators, but that’s not the case yet. Solution Download v1.203 · How to install · News & updates Fira Code is an extension of the Fira Mono font containing a set of ligatures for common programming multi-character combinations.

  • How to Access Python for Doing Scientific Computing
    How to access Python for doing scientific computing1 Hans Petter Langtangen1,2 1Center for Biomedical Computing, Simula Research Laboratory 2Department of Informatics, University of Oslo Mar 23, 2015 A comprehensive eco system for scientific computing with Python used to be quite a challenge to install on a computer, especially for newcomers. This problem is more or less solved today. There are several options for getting easy access to Python and the most important packages for scientific computations, so the biggest issue for a newcomer is to make a proper choice. An overview of the possibilities together with my own recommendations appears next. Contents 1 Required software2 2 Installing software on your laptop: Mac OS X and Windows3 3 Anaconda and Spyder4 3.1 Spyder on Mac............................4 3.2 Installation of additional packages.................5 3.3 Installing SciTools on Mac......................5 3.4 Installing SciTools on Windows...................5 4 VMWare Fusion virtual machine5 4.1 Installing Ubuntu...........................6 4.2 Installing software on Ubuntu....................7 4.3 File sharing..............................7 5 Dual boot on Windows8 6 Vagrant virtual machine9 1The material in this document is taken from a chapter in the book A Primer on Scientific Programming with Python, 4th edition, by the same author, published by Springer, 2014. 7 How to write and run a Python program9 7.1 The need for a text editor......................9 7.2 Spyder................................. 10 7.3 Text editors.............................. 10 7.4 Terminal windows.......................... 11 7.5 Using a plain text editor and a terminal window......... 12 8 The SageMathCloud and Wakari web services 12 8.1 Basic intro to SageMathCloud...................

  • Anaconda Spyder
    Episode 1 Using the Interpreter Anaconda We recommend, but do not require, the Anaconda distribution from Continuum Analytics (www.continuum.io). An overview is available at https://docs.continuum.io/anaconda. At the time the videos were produced, Anaconda distributed a frontend called Navigator. Through Navigator you can launch applications, manage your installation, and install new applications. Continuum provides documentation for Navigator at https://docs.continuum.io/anaconda/navigator. For an easy-to-use tool you can use from the command line, try conda. From Windows, run conda in the command prompt. From Mac OSX or Linux, open a terminal (Apps/Utilities on OSX). The conda cheat sheet (https://conda.io/docs/_downloads/conda-cheatsheet.pdf) is particularly helpful. Using conda you can update everything from a single package to the entire Anaconda distribution. You can also set up your environment to run both Python 2.7 and a version of Python 3. It is important to install Anaconda "Install for Me Only." You can find detailed installation instructions for your platform at https://docs.continuum.io/anaconda/install. It would be a good idea to open a command line and type conda install anaconda-clean so that you can completely uninstall the distribution should the need arise. Spyder We do strongly recommend the free, open-source Spyder Integrated Development Environment (IDE) for scientific and engineering programming, due to its integrated editor, interpreter console, and debugging tools. Spyder is included in Anaconda and other distributions, or it can be obtained from Github (https://github.com/spyder-ide/spyder). The official Spyder documentation is at https://pythonhosted.org/spyder; however, we recommend that beginners start with the tutorial included with Spyder.

  • Software Debugging with Dynamic Instrumentation and Test±Based Knowledge
    SOFTWARE DEBUGGING WITH DYNAMIC INSTRUMENTATION AND TEST±BASED KNOWLEDGE A Thesis Submitted to the Faculty of Purdue University by Hsin Pan In Partial Ful®llment of the Requirements for the Degree of Doctor of Philosophy August 1993 ii To My Family. iii ACKNOWLEDGMENTS I would ®rst like to express my grateful acknowledgement to my major professors, Richard DeMillo and Eugene Spafford, for their patience, support, and friendship. Pro- fessor DeMillo motivated me to study software testing and debugging, and who provided many helpful ideas in this research as well as the area of software engineering. The en- couragement, valuable criticism, and expert advice on technical matters by my co-advisor, Eugene Spafford, have sustained my progress. In particular, I thank Professor Richard Lipton of Princeton University for suggesting the idea of Critical Slicing. I thank my committee members Professors Aditya Mathur and Buster Dunsmore for their suggestions and discussion. I am also thankful to Stephen Chapin, William Gorman, R. J. Martin, Vernon Rego, Janche Sang, Chonchanok Viravan, Michal Young, and many others with whom I had valuable discussion while working on this research. My ex-of®cemates, Hiralal Agrawal and Edward Krauser, deserve special recognition for developing the prototype debugging tool, SPYDER. Bellcore's agreement to make ATAC available for research use at Purdue is acknowledged. Finally, my sincere thanks go to my parents Chyang±Luh Pan and Shu±Shuan Lin, and my wife Shi±Miin Liu, for their love, understanding, and support. I am especially grateful for my wife's efforts in proofreading part of this thesis and her advice on writing.
