WebAssembly, colloquially known as Wasm, is a specification for an intermediate representation that is suitable for the web environment, particularly in the client-side. It provides a machine abstraction and hardware-agnostic instruction sets, where a high-level programming language can target the compilation to the Wasm instead of specific hardware architecture. The JavaScript engine implements the Wasm specification and recompiles the Wasm instruction to the target machine instruction where the program is executed. Technically, Wasm is similar to a popular virtual machine bytecode, such as Java Virtual Machine (JVM) or Microsoft Intermediate language (MSIL).
There are two major implementations of Wasm, correlated with the two most popular web browsers in the market. These two are the V8 engine by Chromium project and the SpiderMonkey engine by Mozilla. Wasm does not mandate a specific implementation over its specification. Therefore, both engines may employ different mechanisms to apply the specification. These different implementations may open a research question: are both engines implementing the Wasm specification equally?
In this thesis, we are going to explore the internal implementation of the JavaScript engine in regards to the Wasm specification. We experimented using a differential fuzzing technique, in which we test two JavaScript engines with a randomly generated Wasm program and compares its behavior. We executed the experiment to identify any anomalous behavior, which then we analyzed and identified the root cause of the different behavior.
This thesis covers the WebAssembly specification extensively. It discusses several foundational knowledge about the specification that is currently lacking in references. This thesis also presents the instrumentation made to the JavaScript engine to perform the experiment, which can be a foundation to perform a similar experiment. Finally, this thesis analyzes the identified anomaly found in the experiment t

The development and implementation of refresh graphics software for the Vector General Display System on a PDP-11 minicomputer is discussed. Modification and expansion of existing software routines, along with additional software design and development is presented. As an addition to the existing C programming language, a version of BASIC was implemented as a second language capable of utilizing the Vector General software. The unsuccessful implementation of a version of FORTRAN with the display system software and the problems involved are discussed. Conclusions and recommendations are offered, and a detailed user's manual is appended.

The design and implementation of an extension to the Basic programming language for use on the PDP-11/50 computer system has been described. The implementation consists of a compiler which generates code to be assembled and loaded into the computer system. An interface with C programs in the system library, which allows extended Basic to perform as an extensive graphics language, has been discussed. The design goals, solutions, and recommendations for further expansion of the system have been presented. The compiler was implemented in the C-progr amming language with the UNIX operating system as supported by the PDP-11/50 at the Naval Postgraduate School Computer Laboratory.

It is difficult to learn professional courses such as Computer Science without hands-on activities with appropriate technical support. Computer Science programming courses are the core of a Computer Science qualification and some of the learning outcomes of a Computer Science programming course are writing program code, program testing and debugging. Inadequate computers in the computer laboratory and policies that restrict the concept of Bring Your Own Technology (BYOT) inside the computer laboratory posed a challenge to hands-on programming activities. However, students in the Computer Science department at the University of Jos learn computer-coding theory, but unable to have hands-on experience due to several reasons. This research investigates how use of virtual lab on Moodle Learning Management System (LMS) could enhance students acquisition of Java programming skills. The virtual lab provides a lab environment for students to practice programming and experiment concepts learned. Activity Theory was used as a theoretical framework to analyse the activity of Java programming on the virtual lab. Seven participants including the lecturer were enrolled on the Java programming language virtual lab practical sessions for this research work. The research activity system focuses on Java hands-on programming tasks for a period of three weeks and after that data was collected using interview and content generated from the virtual lab activities chats and forum. Interview questions were developed and administered to students, while a semi- structured interview with the lecturer was conducted. iii The data collected from the interviews and the contents collated from chats and forum activities were coded using ICT data analysis tool Nvivo, based on thematic analysis. The data was thoroughly reviewed, explained, interpreted, and analysed using the theoretical framework, activity theory. The results show that the virtual lab helped students perform practical programming acti
