interview - Are 9 to 5 programmers looked down upon Manageability - Because Every Complicated Technology Needs It Mercurial SCM Processing.js Basic Syntax A brief look at the structure of a Processing sketch reveals how easy it is to program interactive visualizations. As with any language, you begin by defining your global variables. Then you create a setup() function, where you control the visualization's properties, like the canvas size, frame rate and perhaps variables such as the stoke-weight or background-color. The next step is to create your draw() function, which controls the behavior of each frame in your animation. The draw function loops continuously unless you tell it otherwise by using the exit() command. To the right is a basic example of Processing.js in action. Adding interactivity to your visualization is incredibly simple. Processing.js also tracks a range of pre-defined variables like key, which stores the value of the last key pressed; or mouseX and mouseY, which store the last recorded position of the mouse pointer. Using Processing There are two ways of implementing processing. First Method Needed files:
Apache CXF -- Index Java Business Integration Java Business Integration (JBI) is a specification developed under the Java Community Process (JCP) for an approach to implementing a service-oriented architecture (SOA). The JCP reference is JSR 208 for JBI 1.0 and JSR 312 for JBI 2.0. JBI is built on a Web Services model and provides a pluggable architecture for a container that hosts service producer and consumer components. Services connect to the container via binding components (BC) or can be hosted inside the container as part of a service engine (SE). The services model used is Web Services Description Language 2.0. In-Only: A standard one-way messaging exchange where the consumer sends a message to the provider that provides only a status response.Robust In-Only: This pattern is for reliable one-way message exchanges. To handle functionality that deals with installation, deployment, monitoring and lifecycle concerns amongst BCs and SEs, Java Management Extensions (JMX) is used.

Enterprise service bus All customer services communicate in the same way with the ESB: the ESB translates a message to the correct message type and sends the message to the correct producer service. An enterprise service bus (ESB) is a software architecture model used for designing and implementing communication between mutually interacting software applications in a service-oriented architecture (SOA). As a software architectural model for distributed computing it is a specialty variant of the more general client server model and promotes agility and flexibility with regard to communication between applications. Overview[edit] Duties[edit] An ESB transports the design concept of modern operating systems to networks of disparate and independent computers. The prime duties of an ESB are: Ambiguous use of the term ESB in commerce[edit] History[edit] The first published usage of the term "enterprise service bus" is attributed to Roy W. ESB as software[edit] ESB hive of commodity components Characteristics[edit]
Home | Wappalyzer Basic Work Cycle Subversion has numerous features, options, bells, and whistles, but on a day-to-day basis, odds are that you will use only a few of them. In this section, we'll run through the most common things that you might find yourself doing with Subversion in the course of a day's work. When working on a project that is being modified via multiple working copies, you'll want to update your working copy to receive any changes committed from other working copies since your last update. Use svn update to bring your working copy into sync with the latest revision in the repository: $ svn update Updating ' In this case, it appears that someone checked in modifications to both foo.c and bar.c since the last time you updated, and Subversion has updated your working copy to include those changes. When the server sends changes to your working copy via svn update, a letter code is displayed next to each item to let you know what actions Subversion performed to bring your working copy up to date. svn add FOO ?
Remote file inclusion Code execution on the web serverCode execution on the client-side such as JavaScript which can lead to other attacks such as cross site scripting (XSS).Denial of Service (DoS)Data Theft/Manipulation Programming languages[edit] PHP[edit] Example[edit] Consider this PHP script which includes a file specified by request: <form method="get"><select name="COLOR"><option value="red">red</option><option value="blue">blue</option></select><input type="submit"></form> The developer intended only blue.php and red.php to be used as options. /vulnerable.php? Local File Inclusion[edit] Local File Inclusion (LFI) is similar to a Remote File Inclusion vulnerability except instead of including remote files, only local files i.e. files on the current server can be included.

Cross-site scripting Background[edit] Security on the web is based on a variety of mechanisms, including an underlying concept of trust known as the same origin policy. This essentially states that if content from one site (such as is granted permission to access resources on the system, then any content from that site will share these permissions, while content from another site ( will have to be granted permissions separately. Cross-site scripting uses known vulnerabilities in web-based applications, their servers, or plug-in systems on which they rely. XSS vulnerabilities have been reported and exploited since the 1990s. Types[edit] There is no single, standardized classification of cross-site scripting flaws, but most experts distinguish between at least two primary flavors of XSS: non-persistent and persistent. Non-persistent[edit] A reflected attack is typically delivered via email or a neutral web site. Persistent[edit] Exploit examples[edit]
SQL injection A classification of SQL injection attacking vector as of 2010. SQL injection attacks allow attackers to spoof identity, tamper with existing data, cause repudiation issues such as voiding transactions or changing balances, allow the complete disclosure of all data on the system, destroy the data or make it otherwise unavailable, and become administrators of the database server. In a 2012 study, it was observed that the average web application received 4 attack campaigns per month, and retailers received twice as many attacks as other industries.[2] History[edit] The first public discussions of SQL injection started appearing around 1998;[3] for example, a 1998 article in Phrack Magazine.[4] Form[edit] SQL injection (SQLI) is considered one of the top 10 web application vulnerabilities of 2007 and 2010 by the Open Web Application Security Project.[5] In 2013, SQLI was rated the number one attack on the OWASP top ten.[6] There are four main sub-classes of SQL injection: 1;DROP TABLE users
15. Expression-Based Access Control Method security is a bit more complicated than a simple allow or deny rule. Spring Security 3.0 introduced some new annotations in order to allow comprehensive support for the use of expressions. 15.3.1 @Pre and @Post Annotations There are four annotations which support expression attributes to allow pre and post-invocation authorization checks and also to support filtering of submitted collection arguments or return values. They are @PreAuthorize, @PreFilter, @PostAuthorize and @PostFilter. Their use is enabled through the global-method-security namespace element: Access Control using @PreAuthorize and @PostAuthorize The most obviously useful annotation is @PreAuthorize which decides whether a method can actually be invoked or not. @PreAuthorize("hasRole('ROLE_USER')") public void create(Contact contact); which means that access will only be allowed for users with the role "ROLE_USER". @PreAuthorize("#contact.name == authentication.name") public void doSomething(Contact contact);
