Libros UCLV { BETA }

The 1rst chapters of the book describes the methods and tools required to read program text and convert it into a form suitable for computer manipulation. This process is made in two stages: A lexical analysis stage that basically divides the input text into a list of “words”. This is followed by a syntax analysis (or parsing) stage that analyses the way these words form structures and converts the text into a data structure that reflects the textual structure. Lexical analysis is covered in Chap. 1 and syntactical analysis in Chap. 2. The remainder of the book (Chaps. 3–9) covers the middle part and back-end of interpreters and compilers. Chapter 3 covers how definitions and uses of names (identifiers) are connected through symbol tables. Chapter 4 shows how you can implement a simple programming language by writing an interpreter and notes that this gives a considerable overhead that can be reduced by doing more things before executing the program, which leads to the following chapters about static type checking (Chap. 5) and compilation (Chaps. 6–9. In Chap. 6, it is shown how expressions and statements can be compiled into an intermediate language, a language that is close to machine language but hides machine-specific details. In Chap. 7,it is discussed how the intermediate language can be converted into “real” machine code. Doing this well requires that the registers in the processor are used to store thevalues of variables, which is achieved by a register allocation process, as described in Chap. 8. Up to this point, a “program” has been what corresponds to the body of a single procedure. Procedure calls add some issues, which are discussed in Chap. 9. The book uses standard set notation and equations over sets. Appendix contains a short summary of these, which may be helpful to those that need these concepts refreshed.

SQL

This book is intended for anyone who wants to use the Structured Query Language (SQL) to access a database. It is primarily for programmers and database administrators, but it can also be used by general users using the command line processor. This book is a reference rather than a tutorial. It assumes that you will be writing application programs and therefore presents the full functions of the database manager.

SQL

This book is an attempt to cram the most useful information about SQL into a pocket-size guide. It covers commonly used syntax for the following platforms: IBM DB2 Release 9.7, MySQL 5.1, Oracle Database 11g Release 2, PostgreSQL 9.0, and Microsoft SQL Server 2008 Release 2. Not all syntax will work on all platforms, and some features may not be available in earlier releases of these products. Whenever possible, I’ve tried to note any product or release dependencies.

Programacion para Android

Con el Curso de Programación en Android de sgoliver.net aprenderás a crear desde cero tus propias aplicaciones para dispositivos móviles con sistema operativo Android. Desde los temas más básicos, como descargar e instalar las herramientas necesarias o crear tu primer proyecto paso a paso, hasta temas avanzados como la localización GPS o la comunicación con servicios web. Este manual va dirigido a todas aquellas personas interesadas en un tema tan en auge como la programación de aplicaciones móviles para la plataforma Android. Se tratarán temas dedicados a la construcción de aplicaciones nativas de la plataforma, dejando a un lado por el momento las aplicaciones web. Es por ello por lo que el único requisito indispensable a la hora de utilizar este manual es tener conocimientos bien asentados sobre el lenguaje de programación Java y ciertas nociones sobre aspectos básicos del desarrollo actual como la orientación a objetos.

Programación en R

R in Action provides you with a guided introduction to R, giving you a 2,000-foot view of the platform and its capabilities. It will introduce you to the most important functions in the base installation and more than 90 of the most useful contributed packages. Throughout the book, the goal is practical application—how you can make sense of your data and communicate that understanding to others. When you finish, you should have a good grasp of how R works and what it can do, and where you can go to learn more. You’ll be able to apply a variety of techniques for visualizing data, and you’ll have the skills to tackle both basic and advanced data analytic problems.

Matemáticas

In this edition, we continue to emphasize a balance between theory and applications. Calculus and other types of mathematical support (e.g., linear algebra) are used at about the same level as in previous editions. The coverage of analytical tools in statistics is enhanced with the use of calculus when discussion centers on rules and concepts in probability.

Aborda la creación de documentos en LaTeX de forma abarcadora con todas sus facilidades. Programming in TeX has a very high learning curve, and requires a significant investment of time to build custom macros for text formatting. Fortunately, document preparation systems based on TeX, consisting of collections of pre-built macros, do exist. These pre-built macros are time saving, and automate certain repetitive tasks and help reduce user introduced errors; however, this convenience comes at the cost of complete design flexibility. One of the most popular macro packages is called LaTeX.
