  Host multiple websites in Wamp

I have decided to start playing around with the Zend Framework. I have a web host (of course) however sometimes when developing I find it is easier and faster to use a local web server, with all the bells and whistles. WAMP, LAMP (this link is ubuntu specific, but any linux distribution should have easy HowTo guide for installing the LAMP software stack), MAMP, all provide the basic environment for beginning web development, and some have nice little GUIs to help you con...

  Guest Post from a CodeBoy: The Five Stages of Debugging

Being confronted with a serious and difficult-to-diagnose bug can be one of the most traumatic and stressful experiences of a professional programmer's career. Those who have been through such an ordeal rate the stress as on a par with that accompanying serious injury, divorce, or the death of a family member. Researchers who have studied the psychology of computer programming have lately constructed a framework to understand the stages through which the programmer's mind progresses as she...

  How to handle ES6 modules in NodeJS

In modern JavaScript, there are two types of modules: ES6 module and CommonJS module used by NodeJS. These two types of module are not compatible. Many people would wonder how to load ES6 modules in their NodeJS project. This post will show how this can be done. Difference The syntax of the module being loaded is different. CommonJS modules are loaded with require() and exported with module.exports. ES6 modules are loaded and exported using import and export respectively. Merchanismwise require(...

  Using htpasswd to protect your website in Nginx

We need to build a password protected website frequently such as an internal website within the team, demo website. Here what we are talking about is password protection in Nginx server level instead of application level registration and login. We are going to use Nginx server configuration and htpasswd file to achieve password authentication. The final result looks like below(Different browsers may have different interfaces): If the authentication fails, it will report a HTTP error: 401 Author...

  This Is Why Your Website Is Slow

Click for a larger image Ghostery, the browser plugin that allows its users to "track the trackers," just released data on the tags, widgets and analytics on websites that are the worst in terms of slowing page loads to a crawl. Update: Ghostery discovered an error in their original data set. It appears that Millenial Media was not on this year's list at all, and the #2 slot belonged to AdFunky. Both the text and the graph above have been changed to reflect this. Any webmaster worth his or he...

  An Object is not a Hash

Following my article A String is not an Error, I want to bring attention to an issue that similarly applies to JavaScript in general, but has special relevance in the Node.JS environment. The problem boils down to the usage of {} as a data-structure where the keys are supplied by untrusted user input, and the mechanisms that are normally used to assert whether a key exists. Consider the example of a simple blog created with Express. We decide to store blog posts in memory in a {}, indexed ...

  Check file readability in Java

File operation is quite platform dependent. Although Java is a cross platform programming language, the file operation in Java is also platform dependent. The obvious evidence is the file permission check. In Java, we can call canRead(), canWrite() and canExecutable() to check whether the program can read, write or execute the file specified. However, on Windows, when we call canRead() on a File object, we may get unexpected result. Actually, on Windows, when we call canRead() on a File object, ...
