Pluggable AOP: Designing Aspect Mechanisms for Third-party Composition
Studies of Aspect-Oriented Programming (AOP) usually focus on a language in
which a specific aspect extension is integrated with a base language. Languages
specified in this manner have a fixed, non-extensible AOP functionality. In
this paper we consider the more general case of integrating a base language
with a set of domain specific third-party aspect extensions for that language.
We present a general mixin-based method for implementing aspect extensions in
such a way that multiple, independently developed, dynamic aspect extensions
can be subject to third-party composition and work collaboratively
Comparative Study on Agile software development methodologies
Today-s business environment is very much dynamic, and organisations are
constantly changing their software requirements to adjust with new environment.
They also demand for fast delivery of software products as well as for
accepting changing requirements. In this aspect, traditional plan-driven
developments fail to meet up these requirements. Though traditional software
development methodologies, such as life cycle-based structured and object
oriented approaches, continue to dominate the systems development few decades
and much research has done in traditional methodologies, Agile software
development brings its own set of novel challenges that must be addressed to
satisfy the customer through early and continuous delivery of the valuable
software. It is a set of software development methods based on iterative and
incremental development process, where requirements and development evolve
through collaboration between self-organizing, cross-functional teams that
allows rapid delivery of high quality software to meet customer needs and also
accommodate changes in the requirements. In this paper, we significantly
identify and describe the major factors, that Agile development approach
improves software development process to meet the rapid changing business
environments. We also provide a brief comparison of agile development
methodologies with traditional systems development methodologies, and discuss
current state of adopting agile methodologies. We speculate that from the need
to satisfy the customer through early and continuous delivery of the valuable
software, Agile software development is emerged as an alternative to
traditional plan-based software development methods. The purpose of this paper,
is to provide an in-depth understanding, the major benefits of agile
development approach to software development industry, as well as provide a
comparison study report of ASDM over TSDM.Comment: 25 pages, 25 images, 86 references used, with authors biographie
Early aspects: aspect-oriented requirements engineering and architecture design
This paper reports on the third Early Aspects: Aspect-Oriented Requirements Engineering and Architecture Design Workshop, which has been held in Lancaster, UK, on March 21, 2004. The workshop included a presentation session and working sessions in which the particular topics on early aspects were discussed. The primary goal of the workshop was to focus on challenges to defining methodical software development processes for aspects from early on in the software life cycle and explore the potential of proposed methods and techniques to scale up to industrial applications
The C Object System: Using C as a High-Level Object-Oriented Language
The C Object System (Cos) is a small C library which implements high-level
concepts available in Clos, Objc and other object-oriented programming
languages: uniform object model (class, meta-class and property-metaclass),
generic functions, multi-methods, delegation, properties, exceptions, contracts
and closures. Cos relies on the programmable capabilities of the C programming
language to extend its syntax and to implement the aforementioned concepts as
first-class objects. Cos aims at satisfying several general principles like
simplicity, extensibility, reusability, efficiency and portability which are
rarely met in a single programming language. Its design is tuned to provide
efficient and portable implementation of message multi-dispatch and message
multi-forwarding which are the heart of code extensibility and reusability.
With COS features in hand, software should become as flexible and extensible as
with scripting languages and as efficient and portable as expected with C
programming. Likewise, Cos concepts should significantly simplify adaptive and
aspect-oriented programming as well as distributed and service-oriented

Using the Internet of Things to Teach Good Software Engineering Practice to High School Students
This paper describes a course to introduce high school students
to software engineering in practice using the Internet Of
Things (IoT). IoT devices allow students to get quick, visible
results without watering down technical aspects of
programming and networking. The course has three broad
goals: (1) to make software engineering fun and applicable,
with the aim of recruiting traditionally underrepresented
groups into computing; (2) to make young students begin to
approach problems with a design mindset; and (3) to show
students that computer science, generally, and software
engineering, specifically, is about much more than
programming. The course unfolds in three segments. The first
is a whirlwind introduction to a subset of IoT technologies.
Students complete a specific task (or set of tasks) using each
technology. This segment culminates in a “do-it-yourself”
project, in which the students implement a simple IoT
application using their basic knowledge of the technologies.
The course’s second segment introduces software engineering
practices, again primarily via hands-on practical tutorials. In
the third segment of the course, the students conceive of,
design, and implement a project that uses the technologies
introduced in the first segment, all while being attentive to the
good software engineering practices acquired in the second
segment. In addition to presenting the course curriculum, the
paper also discusses a first offering of the course in a threeweek
summer intensive program in 2017, including
assessments done to evaluate the curriculum.Cockrell School of Engineerin
