While there are many books on
learning PHP and developing
small applications with it, there is
a serious lack of information on
scaling PHP for large-scale,
Schlossnagle’s Advanced PHP
Programming fills that void,
demonstrating that PHP is ready
for enterprise Web applications
by showing the reader how to
develop PHP-based applications

No programmer, no matter how good (s)he is, writes bug−free code all the time. And so, most programming
languages come with built−in capabilities to catch errors and take remedial action. This action could be
something as simple as displaying an error message, or as complex as heating your computer's innards until
they burst into flame (just kidding!)
Over the next couple of pages, we're going to look at some of the error−management techniques available in
JSP, and also demonstrate some of the JSP directives used to integrate standalone JavaBeans into your JSP
This book is a step-by-step tutorial and is packed with practical examples that will make learning JIRA easy. If you want to get started with JIRA, then this is the perfect book for you. You will need to be familiar with basic computer knowledge for your or your organization's standard operating environment and to have experience with software project management.
The Product Backlog will include a variety of items, such as features (“enable all users to place
book in shopping cart”), development requirements (“rework the transaction processing
module to make it scalable”), exploratory work (“investigate solutions for speeding up credit
card validation”), and known bugs (“diagnose and fix the order processing script errors”).
Many people like to articulate the requirements in terms of “user stories”: concise, clear
descriptions of the functionality in terms of its value to the end user of the product.
The technical and nontechnical vulnerabilities associated with an IT system’s processing environment can be identified via the information-gathering techniques described in Section
3.1.2. A review of other industry sources (e.g., vendor Web pages that identify system bugs and flaws) will be useful in preparing for the interviews and in developing effective questionnaires to identify vulnerabilities that may be applicable to specific IT systems (e.g., a specific version of a specific operating system).
A computer program in the form of a human-readable, computer programming language is called source code. Source code may be converted into an executable image by a compiler or executed immediately with the aid of an interpreter.
Some DoS attacks can be avoided by applying vendor patches to affected software. For
example, many vendors have patched their IP implementations to prevent intruders from
taking advantage of the IP reassembly bugs. A few DoS attacks cannot be stopped, but their
scope of affected areas can be constrained.
Document external code dependencies and include these in the packaging if possible.
Correct behaviour of software usually depends on the build environment and a large number
of external components. Wherever possible the development and packaging should actively
prevent an insecure deployment by dependency management. However, it should be noted
that overly strict and detailed dependency specification may lead to restrictions in
One hindrance to this flow of information is not a lack of creative minds to dream up new
services nor lack of an educated workforce to develop enabling technology, but the pres-
ence of mistake and malice, error and evil. The growing interconnectedness of networks
means that systems are open to disruptions from a larger number of machines, software,
and users that can foul the system with faults, bugs, and error.
Computer programs may be categorized along functional lines. The main functional categories are system software and application software. System software includes the operating system which couples computer hardware with application software. The purpose of the operating system is to provide an environment in which application software executes in a convenient and efficient manner. In addition to the operating system, system software includes utility programs that help manage and tune the computer. If a computer program is not system software then it is application software.
This book is a collection of recipes for the working Linux sysadmin–a set of stand-alone quick guides
and tips that you can keep on your desk for easy reference. Hardcore in-depth manuals are great when
you have the time to sit down and read through them thoroughly, but that’s not always the case when
you have a bug that you needed fixed yesterday. This book is aimed at giving you tools to fix problems
faster but also to help you set up software and systems to avoid problems showing up in the first place.
Or at least to help you catch them sooner and solve...
Cory Doctorow (born July 17, 1971) is a blogger, journalist and science
fiction author who serves as co-editor of the blog Boing Boing. He is in
favor of liberalizing copyright laws, and a proponent of the Creative
Commons organisation, and uses some of their licenses for his books.

This book is the definitive guide to the application of agile development with Scrum and modern software engineering practices using Visual Studio 2010. You’ll learn how to use Visual Studio 2010 to empower and engage multidisciplinary, self-managing teams and provide the transparency they need to maximize productivity. Along the way, Guckenheimer and Loje help you overcome every major impediment that leads to stakeholder dissatisfaction—from mismatched schedules to poor quality, blocked builds to irreproducible bugs, and technology “silos” to geographic “silos.”...
