Software is today used in more and different ways than ever before. From refrigerators
and cars to space shuttles and smart cards. As such, most software, usually need to
adhere to a specification, i.e. to make sure that it does what is expected.
Normally, a software engineer goes through a certain process to establish that the
software follows a given specification. This process, verification and validation (V
& V), ensures that the software conforms to its specification and that the customers
ultimately receive what they ordered.
Noted software expert Robert C. Martin presents a revolutionary paradigm with Clean Code: A Handbook of Agile Software Craftsmanship . Martin has teamed up with his colleagues from Object Mentor to distill their best agile practice of cleaning code “on the fly” into a book that will instill within you the values of a software craftsman and make you a better programmer–but only if you work at it.

The goal of the course is to increase the competence in key areas related to engineering of software qualities and by this establish a common platform and understanding. The latter should in the long run make it easier to perform future cooperation and joint projects. We will also discuss techniques and criteria for reviewing scientific papers and book chapters. The course is divided into a number of sections, where one (or a group of) student(s) is responsible for each section. Each section should be documented in written form......
Interested in developing embedded systems? Since they don't tolerate inefficiency, these systems require a disciplined approach to programming. This easy-to-read guide helps you cultivate a host of good development practices, based on classic software design patterns and new patterns unique to embedded programming. Learn how to build system architecture for processors, not operating systems, and discover specific techniques for dealing with hardware difficulties and manufacturing requirements.
Embedded systems are no longer resembled t from our lives without them. Because of their specialization of these are realized increasingly interacting hardware and software components. This makes a holistic, about hardware and software boundaries, continuous amplification ndnis problem of verification is required. This textbook serves as an introduction to guide the systematic verification of embedded systems, both in specialized procedures for hardware and software verification and the verification of the interfaces.
This manual provides descriptions and examples of S7 functions FCs and function blocks FBs in ladder logic (LAD) representation. These FCs and FBs are available to program your S7-300/S7-400 programmable logic controller (PLC). This manual is intended as a reference to provide the necessary information for each function.
The FCs and FBs described in this manual are located in the Standard Library of STEP 7. Using your STEP 7 file manager, you can copy the FCs and FBs you need to your destination program directory.
Software security is gaining momentum as security professionals realize that computer
security is really all about making software behave. The publication of Building Secure
Software in 2001 (Viega and McGraw) unleashed a number of related books that have
crystallized software security as a critical field. Already, security professionals, software
developers, and business leaders are resonating with the message and asking for more.
The Quality Frame can either be applied with or
without the use of a rating scale for each of the key
criteria and standards. Use of a rating scale is a valuable
tool if one wishes to make comparisons between
projects, or if the intention is to gain an overview of
the quality of a large portfolio of projects over time.
In 1993, the first of the GIS Research U.K. (GISRUK) conferences was held at
the University of Keele. Before that, U.K. GIS conferences had been very
broad-based, bringing together the entire spectrum of people who created
and used spatial data and the software to process the data. While such
conferences were very valuable, it was felt that there was also a need for
an academic conference where the focus would be purely on research.
Software error detection is one of the most challenging problems in software engineering. Now, you can learn how to make the most of software testing by selecting test cases to maximize the probability of revealing latent errors. Software Error Detection through Testing and Analysis begins with a thorough discussion of test-case selection and a review of the concepts, notations, and principles used in the book.
Faced with a software project of epic proportions? Tired of over-committing and under-delivering? Enter the dojo of the agile samurai, where agile expert Jonathan Rasmusson shows you how to kick-start, execute, and deliver your agile projects. Combining cutting-edge tools with classic agile practices, The Agile Samurai gives you everything you need to deliver something of value every week and make rolling your software into production a non-event.
Quality means “conformance to requirements”
The best testers can only catch defects that are contrary to specification.
Testing does not make the software perfect.
If an organization does not have good requirements engineering practices then it will be very hard to deliver software that fills the users’ needs, because the product team does not really know what those needs are.
For more than 100 years, Writers’ Workshops have offered writers deep and generous insights into their own work: insights that have helped them improve, and often inspired them to take their work in exciting new directions. Recently, technical, scientific, and business professionals have also discovered the immense value of the Writers’ Workshop format in solving their creative problems. Now, an experienced leader and participant shows how Writers’ Workshops work -- and how they can help everyone from poets to software architects. Richard P.
Business intelligence (BI) software allows you to view different components of a business using a single visual platform, which makes comprehending mountains of data easier. BI is everywhere. Applications that include reports, analytics, statistics, and historical and predictive modeling are all examples of business intelligence. Currently, we are in the second generation of business intelligence software—called BI 2.0—which is focused on writing business intelligence software that is predictive, adaptive, simple, and interactive....
When a computer software succeeds—when it meets the needs of the people
who use it, when it performs flawlessly over a long period of time, when it is
easy to modify and even easier to use—it can and does change things for the better.
But when software fails—when its users are dissatisfied, when it is error prone, when
it is difficult to change and even harder to use—bad things can and do happen. We
all want to build software that makes things better, avoiding the bad things that lurk
in the shadow of failed efforts.
People begin programming before they understand the problem
Everyone likes to feel that they’re making progress
When the team starts to code as soon as the project begins, they see immediate gains
When problems become more complex (as they always do!), the work gets bogged down
In the best case, a team that begins programming too soon will end up writing good software that solves the wrong problem
Software Development and Professional Practice reveals how to design and code great software. What factors do you take into account? What makes a good design? What methods and processes are out there for designing software? Is designing small programs different than designing large ones? How can you tell a good design from a bad one? You'll learn the principles of good software design, and how to turn those principles back into great code.
“New systems generate new problems.” —Murphy’s Technological Laws #17 0.1 An Important Event
On October 19, 1998, the Executive Council of the Association for Computing Machinery (ACM) approved a document titled “The Software Engineering Code of Ethics and Professional Practice”. A few months later, the Board of Governors of the Computer Society of the Institute for Electrical and Electronic Engineers (IEEE-CS) did the same.
Agile software development is a popular development process that continues to reshape philosophies on the connections between disciplined processes and agile practices. In Software Development Rhythms, authors Lui and Chan explain how adopting one practice and combining it with another builds upon the flexibility of agile practices to create a type of "synergy" defined as software development rhythms. The authors demonstrate how these rhythms can be harmonized to achieve synergies, making them stronger together than they would be apart.
