Community Engine is a free, open-source social network plugin for Ruby on Rails applications. Drop it into your new or existing application, and you’ll instantly have all the features of a basic community site.
Features of this social network plugin:
Authentication (sign up, log in)
User profiles
User search
Blogs with tagging, categories and rich text editing
Photo uploading and tagging
“Clippings” - visual bookmarks
Commenting and comment notification by e-mail (Blogs, profiles, photos, and clippings can be commented)
Most of the developers use cookies for storing data on the client side as they are cross browser & platform. But storing important data in cookies has some downsides:
Size: Cookie max size is around 4kb.
Bandwidth: Cookies are used in every HTTP transaction.
Complexity: It is hard to manipulate cookies correctly.
Modern web browsers, Google & Flash have non-cookie storage solutions but each of them solved this differently:
globalStorage: Firefox 2.0+, Internet Explorer 8
localStorage: development WebKit
openDatabase: Safari 3.1+
userdata behavior: Internet Explorer 5.5+
Adobe Flash
Google Gears
PersistJS solves all of the issues above. It currently supports persistent client-side storage through the following backends:
flash: Flash 8 persistent storage.
gears: Google Gears-based persistent storage.
localstorage: HTML5 draft storage.
whatwg_db: HTML5 draft database storage.
globalstorage: HTML5 draft storage (old spec).
ie: Internet Explorer userdata behaviors.
cookie: Cookie-based persistent storage.
And the great news is, each backend is communicated with the same interface which means you don’t have to know or care which backend is being used.
Developers generally neglect JavaScript testing because there’s really nothing out there that let’s you simulate user interactions easily. Here comes the Test plugin (Thanks to Brian Moschel from JavaScriptMVC for suggesting this resource).
It lets you simulate every major DOM event, as well as some combination events like Write and Drag, and then run functional and unit tests in a separate console window.
Test plugin saves serious development time with features like using sample data to simulating AJAX functionality, writing text or dragging an element.
Here is a sample test function:
test_check : function() {
// simulate clicking the checkbox
// params has the todo element
var params = this.TodoCheckClick();
// assert the color change occurs as expected
this.assert_equal("#808080", params.element.parentNode.style.color);
},
test_uncheck : function() {
// click the checkbox again to uncheck it
var params = this.TodoCheckClick();
// assert the color change goes away
this.assert_equal(”, params.element.parentNode.style.color);
},
Requirements: JavaScriptMVC Compatibility: All Major Browsers
There are projects which I’m using Subversion and some that I don’t. There are also other things which are very valuable to me like bookmarks, code snippets & more.
And every designer, developer, for sure, lost a few days work because of not backing up the files regularly.
I have started using Mozy Online Backup Free version as a backup solution for my dev. files in general. It provides 2GB space for free, very easy to configure, can take scheduled backups and works silently.
It is an impressive product as it totally reduces the risk of losing data. And works both in Windows and Mac.
This is an exciting project which helps creating portable, hidden source coded, both online and offline PHP applications.
Roadsend PHP is an open source implementation of the PHP language.
It has a compiler that generates native binaries (no interpreter required) and all source files can be compiled in 1 executable file.
Using Roadsend Compiler, you can:
Create online web applications with Fast/CGI
Offline web applications with an embedded web server (MicroServer)
Desktop GUI applications with PHP-GTK, and console applications.
Once the files are compiled with this PHP compiler, it is close to impossible to return back to the original code. This is a great feature for hiding the source code.
And for easier development & testing, Roadsend has a powerful built-in debugger.
Texter is a simple but effective Windows application running in the system tray and doing a very simple job: replacing abbreviations with the phrases you define.
Let’s say you use XHTML frequently and you define an abbreviation like "divmake" and press "tab" (you can define the hotkey) and it can produce you:
<div class=""></div>
as an example.
You can use it for anything like generating your signature on-the-fly or any other frequently typed text.
When a website visitor faces a JavaScript error, they may not realize it or even they realize it only few of them may inform you about the problem. And you may never find out the problem if someone does not warn you.
DamnIT, built with JavaScriptMVC framework, is a great free service which notifies you when a JavaScript error occurs in your websites via e-mail.
