Regras de declarações. Antes de escavarmos sobre as declarações de classes, vamos fazer uma rápida revisão das regras associadas com declarações de classe, declarações de importação e declarações de pacote em Java. Somente pode haver uma classe pública por código fonte; Comentários podem aparecer no início ou no fim de qualquer linha no código fonte; eles são independentes de qualquer uma das regras posicionamento discutidos aqui. A classe publica tem que ser o nome do arquivo, por exemplo, quando declaramos uma classe chamada public PeterPan o nome do arquivo tem que ser chamada de PeterPan.java Se a classe pertence a um pacote, a declaração do pacote tem que ser feita na primeira linha do programa antes de qualquer importação ou declaração de classe. Se houver declaração de importação ela deve ser feita entre a declaração de pacote (se houver alguma), e a declaração de classe. Isto é, se não houver declaração de pacotes as linhas de importação devem ser escritas dentro da primeira linha do programa. long rg;
PHP - Orientado a Objeto - BloGalizado - Globalizando WebLogs. PHP – Orientado a Objeto O PHP é uma linguagem que nasceu estruturada e vem sendo adaptada ao longo do tempo para trabalhar com os conceitos da Programação Orientada a Objeto, atualmente estamos na versão 5.3.3, e muitos recursos ja estão disponiveis, e muito esta por vir. Até a versão 4.3 o PHP não suportava quase nada de POO (Programação Orientada a Objeto), e até hoje ainda vemos muito código POG (Programação Orientada a Gambiarra) em quase todos os lugares.
Muitos programadores PHP ainda trabalham com códigos estruturados e defendem seus métodos. Podemos definir Orientação a Objetos como um conjunto de técnicas elaboradas para otimizar o processo de desenvolvimento de software, promovendo reaproveitamento de código e encapsulamento de propriedades e comportamentos de objetos do mundo real representado no software em forma de classes.

Hacker Profiling Project (HPP) This is the science of criminal profiling as applied to the world of hacking. Research related to criminal and hacker profiling has been limited to a single point of view: the criminal analysis of the computer intrusion on one side and the technical analysis of the computer intrusion on the other side.
In no case has there been a synergistic approach of those two points of view. The Hacker Profiling Project (HPP) is the means to combine these points of view to define a core methodology which will allow us to profile the attacker based on their techniques in computer-based attacks. This research project aims to identify the real behaviors of each actor through particular technological environments and the social culture of hackers for better identifying their reasons for attacks, the true modus operandi, and to determine better countermeasures to improve security. If you are interested in helping with this project please contact us. Hacking lessons for teens reduce security threats. It might sound strange, but every industry and profession could benefit from an employee as creative, resourceful, and motivated as a hacker. Hackers can teach themselves how things work and how groups of things work together.
Hackers know how to modify things—to adjust, personalize, and even improve them. And it is the hacker whose skillset is diverse, unique, and powerful enough to be dangerous in the hands of the wrong person. Enter ISECOM—a non-profit, open source research group focused on next-generation security and professional security development and accreditation—and its popular project, Hacker Highschool.
Studies have shown that an amateur in any particular field is most likely to entertain the self-delusion that he knows enough to master it. We know how important it is to show teen hackers how to gain knowledge and skills so as to move beyond the amateur level. Hackers unite Our main focus was to teach junior high and highschool students (and their teachers). Hacker Highschool - Security Awareness for Teens.
PHP Freaks - PHP Help Index. Representational state transfer. Representational State Transfer (REST) is a software architecture style consisting of guidelines and best practices for creating scalable web services.[1][2] REST is a coordinated set of constraints applied to the design of components in a distributed hypermedia system that can lead to a more performant and maintainable architecture.[3] REST has gained widespread acceptance across the Web[citation needed] as a simpler alternative to SOAP and WSDL-based Web services.
RESTful systems typically, but not always, communicate over the Hypertext Transfer Protocol with the same HTTP verbs (GET, POST, PUT, DELETE, etc.) used by web browsers to retrieve web pages and send data to remote servers.[3] The REST architectural style was developed by W3C Technical Architecture Group (TAG) in parallel with HTTP 1.1, based on the existing design of HTTP 1.0.[4] The World Wide Web represents the largest implementation of a system conforming to the REST architectural style. Architectural properties[edit]

JavaScript is classified as a prototype-based scripting language with dynamic typing and first-class functions. This mix of features makes it a multi-paradigm language, supporting object-oriented,[6] imperative, and functional[1][7] programming styles. JavaScript has been standardized in the ECMAScript language specification. History[edit] Beginnings at Netscape[edit] JavaScript was originally developed by Brendan Eich, while working for Netscape Communications Corporation. Although it was developed under the name Mocha, the language was officially called LiveScript when it first shipped in beta releases of Netscape Navigator 2.0 in September 1995, but it was renamed JavaScript[10] when it was deployed in the Netscape browser version 2.0B3.[11] The change of name from LiveScript to JavaScript roughly coincided with Netscape adding support for Java technology in its Netscape Navigator web browser.
Server-side JavaScript[edit] Adoption by Microsoft[edit] Standardization[edit] Trademark[edit] JScript. JScript is Microsoft's dialect of the ECMAScript standard[2] that is used in Microsoft's Internet Explorer. JScript is implemented as a Active Scripting engine. This means that it can be "plugged in" to OLE Automation applications that support Active Scripting, such as Internet Explorer, Active Server Pages, and Windows Script Host.[3] It also means such applications can use multiple Active Scripting languages (e.g., JScript, VBScript, PerlScript, etc.). JScript was first supported in the Internet Explorer 3.0 browser released in August 1996. Its most recent version is JScript 9.0, included in Internet Explorer 9. JScript 10.0[4] is a separate dialect, also known as JScript .NET, which adds several new features from the abandoned fourth edition of the ECMAScript standard.
Comparison to JavaScript[edit] As explained by JavaScript guru Douglas Crockford in his talk titled The JavaScript Programming Language on YUI Theater, Versions[edit] JScript[edit] JScript .NET[edit] See also[edit] Notes[edit] XHTML. XHTML (Extensible HyperText Markup Language) is a family of XML markup languages that mirror or extend versions of the widely used Hypertext Markup Language (HTML), the language in which web pages are written. While HTML (prior to HTML5) was defined as an application of Standard Generalized Markup Language (SGML), a very flexible markup language framework, XHTML is an application of XML, a more restrictive subset of SGML. Because XHTML documents need to be well-formed, they can be parsed using standard XML parsers—unlike HTML, which requires a lenient HTML-specific parser. XHTML 1.0 became a World Wide Web Consortium (W3C) Recommendation on January 26, 2000. XHTML 1.1 became a W3C Recommendation on May 31, 2001.
The standard known as XHTML5 is currently developed as XML serialization of HTML5 spec.[1][2] Overview[edit] However, in 2005, the Web Hypertext Application Technology Working Group (WHATWG) formed, independently of the W3C, to work on advancing ordinary HTML not based on XHTML. The Hello World Collection. Since then, Hello World has been implemented in just about every programming language on the planet. This collection includes 441 Hello World programs in many more-or-less well known programming languages, plus 64 human languages. The programs in this collection are intended to be as minimal as possible in the respective language. They are meant to demonstrate how to output Hello World as simply as possible, not to show off language features.
For a collection of programs that tell more about what programming in the languages actually is like, have a look at the 99 Bottles of Beer collection. The Collection was compiled by Wolfram Rösler with help from many people around the world. It was started on 3-Oct-1994, put on the Internet on 30-Dec-1999, exceeded 200 entries on 14-Jul-2005, 300 on 6-Dec-2006, and 400 on 27-Jul-2008. It is now probably the biggest collection of Hello World programs on the Internet, and the only one collecting human languages as well.

Uma linguagem de programação é um método padronizado para comunicar instruções para um computador.[1] É um conjunto de regras sintáticas e semânticas usadas para definir um programa de computador.[2] [Nota 1] Permite que um programador especifique precisamente sobre quais dados um computador vai atuar, como estes dados serão armazenados ou transmitidos e quais ações devem ser tomadas sob várias circunstâncias. Linguagens de programação podem ser usadas para expressar algoritmos com precisão. O conjunto de palavras (lexemas classificados em tokens), compostos de acordo com essas regras, constituem o código fonte de um software.[3] Esse código fonte é depois traduzido para código de máquina, que é executado pelo processador.[3] Linguagens de programação também tornam os programas menos dependentes de computadores ou ambientes computacionais específicos (propriedade chamada de portabilidade[5] ).
