  • Thriving in a Crowded and Changing World: C++ 2006–2020
    Thriving in a Crowded and Changing World: C++ 2006–2020 BJARNE STROUSTRUP, Morgan Stanley and Columbia University, USA Shepherd: Yannis Smaragdakis, University of Athens, Greece By 2006, C++ had been in widespread industrial use for 20 years. It contained parts that had survived unchanged since introduced into C in the early 1970s as well as features that were novel in the early 2000s. From 2006 to 2020, the C++ developer community grew from about 3 million to about 4.5 million. It was a period where new programming models emerged, hardware architectures evolved, new application domains gained massive importance, and quite a few well-financed and professionally marketed languages fought for dominance. How did C++ ś an older language without serious commercial backing ś manage to thrive in the face of all that? This paper focuses on the major changes to the ISO C++ standard for the 2011, 2014, 2017, and 2020 revisions. The standard library is about 3/4 of the C++20 standard, but this paper’s primary focus is on language features and the programming techniques they support. The paper contains long lists of features documenting the growth of C++. Significant technical points are discussed and illustrated with short code fragments. In addition, it presents some failed proposals and the discussions that led to their failure. It offers a perspective on the bewildering flow of facts and features across the years. The emphasis is on the ideas, people, and processes that shaped the language. Themes include efforts to preserve the essence of C++ through evolutionary changes, to simplify itsuse,to improve support for generic programming, to better support compile-time programming, to extend support for concurrency and parallel programming, and to maintain stable support for decades’ old code.

It seems like everyone these days is downloading, watching, and sharing videos from video-sharing sites like YouTube, Google Video, MetaCafe, DailyMotion, Veoh, Break, and a ton of other similar sites. Whether you want to watch the video on your iPod while working out, insert it into a PowerPoint presentation to add some spice, or simply download a video before it’s removed, it’s quite essential to know how to download, convert, and play these videos. There are basically two ways to download videos off the Internet and that’s how I’ll split up this post: either via a web app or via a desktop application. Personally, I like the web applications better simply because you don’t have to clutter up and slow down your computer with all kinds of software! UPDATE: MakeUseOf put together an excellent list of the best websites for watching movies, TV shows, documentaries and standups online.

    Gtk2-Perl: An Introduction Gtk2-Perl: An Introduction Or How I Learned to Stop Worrying and Make Things Pretty Scott Paul Robertson http://spr.mahonri5.net [email protected] May 9, 2007 Gtk2-Perl: An Introduction Background What is Gtk2-Perl? Gtk2-Perl is the set of Perl bindings for Gtk2, and related libraries1. These allow you to code Gtk2 and Gnome applications in Perl. Gtk2-Perl is fairly easy to get started using, but has a few hang ups that can be difficult to discover, or sometimes the documentation is just not there. The developers are aware of the issue, and encourage users to provide documentation, reference guides, or tutorials. 1Glade, Glib, etc Gtk2-Perl: An Introduction Background Online Documentation There are a few major online sources for Gtk2-Perl documentation: ◮ Gtk2-Perl Tutorial - The offical tutorial. ◮ Gtk2-Perl Study Guide - Another excellent tutorial/reference ◮ Introduction to GUI Programming with Gtk2-Perl - As it says, it’s a good introduction to gui programming in general. ◮ Gtk2-Perl Pod Documentation - You might have these as man pages as well, very helpful. Gtk2-Perl: An Introduction Basic Application A Simple Window We’ll start with an example of a simple single button application. First we have to initalize Gtk2: #!/usr/bin/perl -w use strict; use Gtk2 ’-init’; use readonly TRUE => 1; use readonly FALSE => 0; ◮ The ’-init’ prepares the Gtk2 environment, otherwise we would have to do it ourselves later. ◮ Defining the constants is very helpful for code readability later. Gtk2-Perl: An Introduction Basic Application A Simple Window Now we set up the window object and a button.

  • GTK+ Properties
    APPENDIX A ■ ■ ■ GTK+ Properties GObject provides a property system, which allows you to customize how widgets interact with the user and how they are drawn on the screen. In the following sections, you will be provided with a complete reference to widget and child properties available in GTK+ 2.10. GTK+ Properties Every class derived from GObject can create any number of properties. In GTK+, these properties store information about the current state of the widget. For example, GtkButton has a property called relief that defines the type of relief border used by the button in its normal state. In the following code, g_object_get() was used to retrieve the current value stored by the button’s relief property. This function accepts a NULL-terminated list of properties and vari- ables to store the returned value. You can also use g_object_set() to set each object property as well. g_object_get (button, "relief", &value, NULL); There are a great number of properties available to widgets; Tables A-1 to A-90 provide a full properties list for each widget and object in GTK+ 2.10. Remember that object properties are inherited from parent widgets, so you should investigate a widget’s hierarchy for a full list of properties. For more information on each object, you should reference the API documentation. Table A-1. GtkAboutDialog Properties Property Type Description artists GStrv A list of individuals who helped create the artwork used by the application. This often includes information such as an e-mail address or URL for each artist, which will be displayed as a link.

Researcher Investigating numerically and analytically the Rashba spin-orbit interaction in InSb/AlInSb quantum wells and interacting arrays of CdS/CdSe/CdS quantum well quantum dots. De- veloped software (C, C++) to calculate the charge and spin properties of semiconductor nanostructures. Used GNOME (e.g. glib/GIO), scientific libraries (e.g. FFTW3, GSL), Free and Open Source software (e.g. flex, bison), and high-performance computing technologies (e.g. OpenMP, MPI, CUDA/GPGPU) to quickly, accurately, and flexibly perform calcula- tions in research and educational settings. Used shell scripting and perl to perform needed pre- and postprocessing of data in order to do a large number of calculations and present them coherently and accurately. Organized a scientific conference, working with with others on the organizing committee, vendors, sponsors, and attendees in order to provide a world- class scientific interaction experience to the attendees. Supervised students as they pursued scientific research.
