Robot simulation is an essential tool in every roboticist’s toolbox. A well-designed simulator makes it possible to rapidly test algorithms, design robots, and perform regression testing using realistic scenarios. Gazebo offers the ability to accurately and efficiently simulate populations of robots in complex indoor and outdoor environments. At your fingertips is a robust physics engine, high-quality graphics, and convenient programmatic and graphical interfaces. Best of all, Gazebo is free with a vibrant community.

struct S { A a; B b; C c; };
auto const S_fields = [](S const& obj) -> auto { return std::tie(obj.a, obj.b, obj.c); };
bool operator == (S const& lhs, S const& rhs) { return S_fields(lhs) == S_fields(rhs); }
bool operator < (S const& lhs, S const& rhs) { return S_fields(lhs) < S_fields(rhs); }

Programming Languages – commonly used features in a side-by-side format.

MSTest is used for Managed C#, C++ Tests and Test Execution Command Line Tool (vstest.console.exe) for unmanaged C++ tests.

MSTest example:

>"C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\MSTest.exe" /testcontainer:managed_unitTest.dll /testsettings:mysettings.testsettings

Test Execution Command Line Tool example:

>"C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe" unmanaged_unitTest.dll /Settings:mysettings.testsettings /platform:x86

• The default constructor is auto-generated if there is no user-declared constructor (§12.1/5).
• The copy constructor is auto-generated if there is no user-declared move constructor or move assignment operator (because there are no move constructors or move assignment operators in C++03, this simplifies to “always” in C++03) (§12.8/8).
• The copy assignment operator is auto-generated if there is no user-declared move constructor or move assignment operator (§12.8/19).
• The destructor is auto-generated if there is no user-declared destructor (§12.4/4).

C++0x only:

• The move constructor is auto-generated if there is no user-declared copy constructor, copy assignment operator or destructor, and if the generated move constructor is valid (e.g. if it wouldn’t need to assign constant members) (§12.8/10).
• The move assignment operator is auto-generated if there is no user-declared copy constructor, copy assignment operator or destructor, and if the generated move assignment operator is valid (e.g. if it wouldn’t need to assign constant members) (§12.8/21).

Portable and easy to use editor to write and test C++11 snippets. It integrates Notepad++ and Stephan T. Lavavej’s MinGW Distro (GCC 4.8.1). You can use F9 key to compile C++ files, and Ctrl+F9 to execute the compiled program.

Yesterday (22 Feb, 2014), Apple pushed a rather spooky security update for iOS that suggested that something was horribly wrong with SSL/TLS in iOS but gave no details. Since the answer is at the top of the Hacker News thread, I guess the cat’s out of the bag already and we’re into the misinformation-quashing stage now.

The Visual Studio 2013 C++ compiler has a number of new C++11 features. I’d like to give you a quick overview of these features using examples from the upcoming VS2013 edition of my book, C++11 Rocks.
