Dragonfly.Wpi.Edu/Book/ February 28, 2013 8:8 Computer Science Education Paper
February 28, 2013 8:8 Computer Science Education paper Computer Science Education Vol. XX, No. XX, June 2013, 1–18 RESEARCH ARTICLE Dragonfly – Strengthening Programming Skills by Building a Game Engine from Scratch Mark Claypool Computer Science and Interactive Media & Game Development Worcester Polytechnic Institute, Worcester, MA 01609, USA email: [email protected] (Received 00 Month 200x; final version received 00 Month 200x) Computer game development has been shown to be an effective hook for motivating students to learn both introductory and advanced computer science topics. While games can be made from scratch, to simplify the programming required game development often uses game engines that handle complicated or frequently used components of the game. These game engines present the opportunity to strengthen programming skills and expose students to a range of fundamental computer science topics. While educational efforts have been effective in using game engines to improve computer science education, there have been no published papers describing and evaluating students building a game engine from scratch as part of their course work. This paper presents the Dragonfly-approach in which students build a fully functional game engine from scratch and make a game using their engine as part of a junior-level course. Details on the programming projects are presented, as well as an evaluation of the results from two offerings that used Dragonfly. Student performance on the projects as well as student assessments demonstrate the efficacy of having students build a game engine from scratch in strengthening their programming skills. Keywords: game engine, programming, object-oriented design, software engineering, game development 1 Introduction By the end of their second year, most computer science students have been exposed to a breadth of foundational materials, such as introductory programming, basic data structures and algo- rithms, and have begun to write programs of moderate size – hundreds of lines of code, perhaps up to even a thousand lines of code. -

Majnemer-Fuzzingclang.Pdf
Fuzzing Clang to find ABI Bugs David Majnemer What’s in an ABI? • The size, alignment, etc. of types • Layout of records, RTTI, virtual tables, etc. • The decoration of types, functions, etc. • To generalize: anything that you need N > 1 compilers to agree upon C++: A complicated language union U { int a; int b; }; ! int U::*x = &U::a; int U::*y = &U::b; ! Does ‘x’ equal ‘y’ ? We’ve got a standard How hard could it be? “[T]wo pointers to members compare equal if they would refer to the same member of the same most derived object or the same subobject if indirection with a hypothetical object of the associated class type were performed, otherwise they compare unequal.” No ABI correctly implements this. Why does any of this matter? • Data passed across ABI boundaries may be interpreted by another compiler • Unpredictable things may happen if two compilers disagree about how to interpret this data • Subtle bugs can be some of the worst bugs Finding bugs isn’t easy • ABI implementation techniques may collide with each other in unpredictable ways • One compiler permutes field order in structs if the alignment is 16 AND it has an empty virtual base AND it has at least one bitfield member AND … • Some ABIs are not documented • Even if they are, you can’t always trust the documentation What happens if we aren’t proactive • Let users find our bugs for us • This can be demoralizing for users, eroding their trust • Altruistic; we must hope that the user will file the bug • At best, the user’s time has been spent on something they probably didn’t want to do Let computers find the bugs 1. -

Using Doxygen to Generate Spanish and English Documentation
Seventh LACCEI Latin American and Caribbean Conference for Engineering and Technology (LACCEI’2009) “Energy and Technology for the Americas: Education, Innovation, Technology and Practice” June 2-5, 2009, San Cristóbal, Venezuela. Using Doxygen to generate Spanish and English documentation Adolfo Di Mare Escuela de Ciencias de la Computación e Informática – Universidad de Costa Rica [email protected] ABSTRACT We describe how to use Doxygen to generate specifications for C++ modules both in English and Spanish. The method is simple and also facilitates maintaining documentation in several languages, which helps module and program internationalization. Keywords: documentation, data hidding, software engineering, implementation, abstraccion. Globalization has brought programmers together into a large family that produces every day millions of lines of code. As it has happened many times over, if the program under construction will be used only in rare instances there is a strong possibility that its documentation will not be written. Although at first glance this looks like savings, the developer will soon discover that module specification facilitates his work and shortens the time needed to build programs. The reason for this reality is simple: whoever does not know where he goes, winds up elsewhere (Di Mare, 2007). It is also important to incorporate test data definition in each module specification, as discussed in (Di Mare, 2008). When in here we speak about “languages” it should be understood as “spoken languages” as it is always assumed that programs are written in C++, but the documentation method for multiple languages described in here can be generalized to other computer languages in which the profesional documentation tool Doxygen is used (van Heesch, 2005). -

Wight, Dean of The Graduate School. ABSTRACT ZL is a C++-compatible language in which high-level constructs, such as classes, are defined using macros over a C-like core language. This approach is similar in spirit to Scheme and makes many parts of the language easily customizable. For example, since the class construct can be defined using macros, a programmer can have complete control over the memory layout of objects. Using this capability, a programmer can mitigate certain problems in software evolution such as fragile ABIs (Application Binary Interfaces) due to software changes and incompatible ABIs due to compiler changes. -
