Asynchronous Technologies: AJAX, AJAH, AHAH, and AJAJ
Hey guys and gurls! Today we are going to take a look at different asynchronous technologies. There are many variations of them over the net. Introduction Before we get started, i’ll tell you a little bit more about data transfer solutions… The title AJAX referred to XML, although at present, for asynchronous data transmission, it is used less frequently (in pure form, at least). I will lead examples using jQuery JS framework. jQuery supports all three types of asynchronous data transfer. There is a lot of features to work with AJAX in jQuery, but the main ones being. get () and. gost (). $.post(url[, params[, callback]]) $.get(url[, params[, callback]]) where, url – the address where we should send the POST (GET) request to, params – the parameters (param1: value1, param2: value2), callback – function to be executed after the page returns the answer for the query (as an argument it is passed the answer). Examples index.html version.php echo phpversion(); Using AHAH A quick example Final Notes
A Git Primer
git is a wicked-powerful distributed revision control system. It is confusing to many, so there are myriad tutorials and explanations online to help people understand it. This one will focus on the fundamental concepts and tasks rather than trying to compete with the documentation. “I’m an egotistical bastard, and I name all my projects after myself. First Linux, now git.” ~ Linus Torvalds Definitions Working Directory - the working directory is the directory where you have content that you want to manage with git. Commit - a commit is a full snapshot of the contents of your working directory (everything being tracked by git, anyway), and it’s kept track of using a unique 40 character SHA1 hash. Index - the index can be considered a staging area. Branch - a branch is similar in concept to other versioning systems, but in git it’s simply a pointer to a particular commit. Understanding how these components work together is the key to understanding git. git‘s Index $ git status On branch master Tags
How AJAX Works: 10 Practical Uses For AJAX | Noupe
Jun 14 2009 AJAX has gotten more and more popular over the years, and has allowed web applications to act more and more like desktop applications. AJAX can provide a lot of additional functionality that could not be accomplished any other way. What Is AJAX? AJAX stands for Asynchronous JavaScript and XML. Here is how the usual AJAX script goes: Some action triggers the event, like the user clicking a button.The AJAX call fires, and sends a request to a server-side script, using XMLThe server-side script (PHP, ASP, or whatever) takes the input from JavaScript, can access the database if it needs to, and processes the data.Using XML again, the script sends the data back to the original client-side page that made the requestA second JavaScript function, called a callback function,catches the data, and updates the web page Throughout this tutorial, we will discuss how various scripts use this routine to accomplish a wide variety of effects. 1. Example: Digg.com (top of page) 2. 3. 4. 5. 6. 7.

Free Hadoop Development Environment: Karmasphere Studio
Last week we told you about this tutorial to get started with Hadoop. If you want to go further with Hadoop, you might want a dedicated development environment. Karmasphere offers both a free "community edition" and a paid professional version of its Hadoop development environment for prototyping, development and debugging of Hadoop jobs. Has anyone used it? Some basic technical information from Karmasphere's web site: Runs on Linux, Apple Mac OS and Windows Works with all major distributions and versions of Hadoop including Apache, Yahoo! Of particular note are the various charts and visualization tools that help you track your resource usage and efficiency: These screenshots were captured from this demo video.

Create an In-Place Editing System
Making users click through multiple pages just to edit a field is so 1999. In this tutorial, you'll learn how to create an in-place editing system as found on popular sites, such as Flickr. A word from the Author With all the buzz around Web 2.0, ease of use is now much more important than ever. Being able to edit some content without having to go to another page is something a lot of users really crave. A lot of big names are already using this pattern to great effect. I believe a demo is worth a thousand words. Today, we are going to look at how to implement this with, you guessed it right, our favorite JavaScript library, jQuery. Design Goals Before we start looking at how to implement the functionality, here are a few thoughts about the goals and the resulting decisions. We need to let the user edit the content without leaving the page. Now that we've mapped out our needs we can now move on to how we are going to do this. Plan of Action Core Markup CSS Styling Nothing special here.
