C++ code that compiles links runs does something different than you expect Example: if (-0.5 <= x <= 0.5) return 0; Pitfall: This expression doesnot test the mathematical condition -1.5 <= x <= 1.5 Instead, it first computes -0.5 <= x, which is 0 or 1, and then compares the result with 0.5. Moral: Even though C++ now has a bool type, Booleans are still freely convertible to int. Since bool->int is allowed as a conversion, the compiler cannot check the validity of expressions. Constructor pitfalls int main() { string a("Hello"); string b(); string c = string("World"); // ... return 0; } string b(); This expression does not construct an object b of type string. Moral: Remember to omit the ( ) when invoking the default constructor. The C feature of declaring a function in a local scope is worthless since it lies about the true scope. a = 36; or

argouml.tigris.org Pure JavaScript HTML Parser Recently I was having a little bit of fun and decided to go about writing a pure JavaScript HTML parser. Some might remember my one project, env.js, which ported the native browser JavaScript features to the server-side (powered by Rhino). One thing that was lacking from that project was an HTML parser (it parsed strict XML only). I’ve been toying with the ability to port env.js to other platforms (Spidermonkey derivatives and the ECMAScript 4 Reference Implementation) and if I were to do so I would need an HTML parser. Because of this fact it became easiest to just write an HTML parser in pure JavaScript. I did some digging to see what people had previously built, but the landscape was pretty bleak. (I also contemplated porting the HTML 5 parser, wholesale, but that seemed like a herculean effort.) However, the result is one that I’m quite pleased with. htmlparser.js: 4 Libraries in One! There were four pieces of functionality that I wanted to implement with this library: A SAX-style API
jBPM In essence jBPM takes graphical process descriptions as input. A process is composed of tasks that are connected with sequence flows. Processes represent an execution flow. The graphical diagram (flow chart) of a process is used as the basis for the communication between non-technical users and developers. Each execution of a process definition is called a "process instance". jBPM manages the process instances. jBPM is based on the Process Virtual Machine (PVM) which is the JBoss community's foundation to support multiple process languages natively. As of version 5.0, jBPM also includes powerful business rules and event integration, and support for more advanced, flexible business processes. jBPM version 5 was the result of a merge of the jBPM project with Drools Flow, a sub-project of the Drools system. The current jBPM5 snapshot offers open source business process execution and management, including: See also[edit] External links[edit] Official website
Coreservlets.com: Java, JSF 2, PrimeFaces, Ajax, jQuery, Spring, Hibernate, REST, Hadoop, and GWT Training, Tutorials, Consulting, Books, & Resources ARIS Express ARIS Express is a free-of-charge modeling tool for business process analysis and management. It supports different modeling notations such as BPMN 2, Event-driven Process Chains (EPC), Organizational charts, process landscapes, whiteboards, etc. ARIS Express was initially developed by IDS Scheer, which was bought by Software AG in December 2010. The tool is provided as freeware on ARIS Community webpage. History[edit] ARIS Express was first announced on April 28, 2009 in a press release by IDS Scheer.[1] The first release was on July 28, 2009 in a public beta test on ARIS Community.[2] Only people, who registered before for the beta test were allowed to download and test this beta version. The official release of ARIS Express 1.0 was on September 9, 2009.[4] In this first stable version, features such as Microsoft Visio import were added, which were not present in the version for the public beta test. Functionality[edit] Overview[edit] ARIS Express is a standalone single-user application.
Top 10 Front-End Development Frameworks (Editor’s note: purely for reasons of length and readability, this article is the first of two parts. This one focuses on the Bootstrap family, more will be profiled in the second part.) As the Web matures and the range of mobile devices we use to access it rapidly grows, our jobs as web designers and developers get considerably more complicated. A decade ago things were much simpler. Then, it was almost certain that most of our users were visiting our sites while sitting at their desk, looking at a large monitor. 960 pixels was more or less considered as a good width for a web page. Our main care was dealing with the dozen or so desktop browsers and jumping through a few extra browser hacks to support quirky old versions of Internet Explorer. Soon, more people will be accessing the Web on their mobile and alternate devices than on a desktop computer. One of the primary strategies we use when we deal with unknown viewport size is the so-called responsive web design. 1. 2. 3. 4.
Architecture of Integrated Information Systems Model of the ARIS Framework. ARIS (Architecture of Integrated Information Systems) is an approach to enterprise modeling.[1] It offers methods for analyzing processes and taking a holistic view of process design, management, work flow, and application processing. The ARIS approach not only provides a generic methodological framework but also a business process modeling tool.[2] ARIS started as the academic research of Prof August-Wilhelm Scheer in the 1990s. ARIS techniques[edit] ARIS uses a modeling language known as Event-driven Process Chains (EPC), which is an important aspect of the ARIS-model. Recent versions of the ARIS Toolset also support the Business Process Model and Notation (BPMN) in order to model business processes. ARIS varies four main perspectives of techniques (see image): Organizational viewData viewControl viewFunctional view It differs from swim lane in that it is process-oriented whiles swim lanes are function-oriented.

Take Your HTML Tables to a New Level with JavaScript Frameworks Take Your HTML Tables to a New Level with JavaScript Frameworks With basic HTML tables, the structure and the way the table are presented inherits the native html style. And if you like to change it then you need to change the underlying HTML code or spend time in adding attributes to all tables tags, in order to style it with CSS . But what if you want to make the tables more interesting, more dynamic, more visual appealing without spending so much time. Yes you can certainly use JavaScript for this, but coding it from scratch will be time consuming and it’s not worth. But JS libraries/frameworks will allow you to add a range of dynamic behavior to your tables and manipulate it for better presentation on a webpage without spending much time. Solutions Based on jQuery Flexigrid Flexigrid is a lightweight plug-in for jQuery that converts an ordinary HTML table into an extremely flexible and feature-rich datagrid (or Flexigrid). tablesorter TableRowCheckboxToggle TableEditor ingrid DataTables
