Microsoft’s ADO.NET Entity Framework, known widely as EF, introduced out-of-thebox
Object Relational Mapping to .NET and Visual Studio. Central to Entity Framework
was the Entity Data Model, a conceptual model of your application domain that
maps back to the schema of your database. This conceptual model describes the core
classes in your application. Entity Framework uses this conceptual model while querying
from the database, creating objects from that data and then persisting changes back
to the database....
Low-density parity-check (LDPC) codes are forward error-correction codes,
first proposed in the 1962 PhD thesis of Gallager at MIT. At the time, their
incredible potential remained undiscovered due to the computational demands
of simulation in an era when vacumm tubes were only just being replaced by
the first transistors. They remained largely neglected for over 35 years. In the
mean time the field of forward error correction was dominated by highly structured
algebraic block and convolutional codes.
There's a common belief that cyberspace cannot be regulated-that it is, in its very essence, immune from the government's (or anyone else's) control. Code, first published in 2000, argues that this belief is wrong. It is not in the nature of cyberspace to be unregulable; cyberspace has no ?nature.” It only has code-the software and hardware that make cyberspace what it is. That code can create a place of freedom-as the original architecture of the Net did-or a place of oppressive control. Under the influence of commerce, cyberspace is ...

.Praise for Head First OOA&D
“Head First Object-Oriented Analysis and Design is a refreshing look at the subject of OOA&D. What sets this book apart is its focus on learning. There are too many books on the market that spend a lot of time telling you why, but do not actually enable the practitioner to start work on a project. Those books are very interesting, but not very practical. I strongly believe that the future of software development practice will focus on the practitioner.
"Refactoring" was conceived in Smalltalk circles, but it wasn't long before it found its way into
other programming language camps. Because refactoring is integral to framework development,
the term comes up quickly when "frameworkers" talk about their craft. It comes up when they
refine their class hierarchies and when they rave about how many lines of code they were able to
delete. Frameworkers know that a framework won't be right the first time around—it must evolve
as they gain experience.
“I received the book yesterday and started to read it on the way home... and I couldn’t stop. I took it to the gym and I expect people saw me smiling a lot while I was exercising and reading. This is tres ‘cool’. It is fun but they cover a lot of ground and they are right to the point. I’m really impressed.” — Erich Gamma, IBM Distinguished Engineer, and co-author of Design Patterns “‘Head First Design Patterns’ manages to mix fun, belly-laughs, insight, technical depth and great practical advice in one entertaining and thought provoking read. Whether you are...
Head First Python“is a great introduction to not just the Python language, but Python as it’s used in the real world. The book goes beyond the syntax to teach you how to create applications for Android phones, Google’s App Engine, and more.” — David Griffiths, author and Agile coach “Where other books start with theory and progress to examples, Head First Python jumps right in with code and explains the theory as you read along. This is a much more effective learning environment, because it engages the reader to do from the very beginning. It was also just a joy...
Learning to design objects effectively with Java is the goal of Beginning Java Objects: From Concepts to Code, Second Edition. Plenty of titles dig into the Java language in massive detail, but this one takes the unique approach of stepping back and looking at fundamental object concepts first. Mastery of Java—from understanding the basic language features to building complete industrial-strength Java applications—emerges only after a thorough tour of thinking in objects.
“The great thing about this book is its simple, step-by-step approach. It doesn’t try to teach everything—it just launches you right into building iPhone applications in a friendly, conversational way. It’s a fantastic book for people who already know how to write code and just want to get straight into the meat of building iPhone applications.” — Eric Shephard, owner of Syndicomm

In Learning iOS Game Programming, you’ll learn how to build a 2D tile map game, Sir Lamorak’s Quest: The Spell of Release (which is free in the App Store). You can download and play the game you’re going to build while you learn about the code and everything behind the scenes. Daley identifies the key characteristics of a successful iPhone game and introduces the technologies, terminology, and tools you will use.
This section is dedicated to those who would like to write a
virus, but don't have the knowledge to do so. First of all,
writing a virus is no big deal. It is an easy project, but one
which requires some basic programming skills, and the desire to
write a virus! If either of these is missing, writing a virus
would be tedious indeed!.
Non coding endogenous RNAs were first discovered in the last decade of the previous
century. These new discoveries changed our views of the transcriptome landscape of
plant genomes and paradigms of the regulation of gene expression. With the beginning
of this century, we have witnessed an explosion of studies on small regulatory
RNAs that has yielded a basic understanding of the many types of small RNAs in
diverse eukaryotic species and how they are functioning as RNA–protein complexes
along the RNA silencing pathways.
To accomplish the sad duty of paying homage to Alain Glavieux, I have referred
to his biography as much as my own memories. Two points of this biography struck
me, although I had hardly paid attention to them until now. I first noted that Alain
Glavieux, born in 1949, is the exact contemporary of information theory, since it
was based on the articles of Shannon in 1948 and 1949. I also noted that his first
research at the Ecole Nationale Supérieure de Télécommunications de Bretagne
(ENST Brittany) related to underwater acoustic communications. ...

Some of the meaning of a discourse is encoded in its linguistic forms. Thls is the truth-conditional meaning of the propositions those forms express and entail. Some of the meaning is suggested (or 'implicated', as Grice would say) by the fact that the encooer expresses just those propositions in just those linguistic forms in just the given contexts [ 2 ] . The first klnd of meaning is usually labeled 'semantics'; it is decoded. The second Is usually labeled 'pragmatlcs'; it is inferred from clues provided by code and context. Both kinds of meaning are related to syntax in...
When symfony first appeared in October 2005, many people heard about it mainly because of
its extensive documentation. Unlike with other open source projects, you don’t have to dig into
the symfony code to understand how a method works or what a feature does. Documentation
has always been a major concern among the symfony core team, and that’s why we wrote this
book: to leverage the adoption of the framework we initiated, to serve as a reference for the
1.0 release, and to allow enterprise use of a framework written primarily for professionals.
