TraceMonkey: Another Curious George

June 21, 2009

TraceMonkey is an updated version of Mozilla Firefox’s JavaScript engine. So what’s so great about it? It’s a looooot faster! Mozilla executives has been stated saying that this new engine is 20 to 40 times more faster than the previous JavaScript engines.

Though we all know that Mozilla has a reputation to give their products some really slick names, TraceMonkey has actually been derived from an earlier JavaScript engine then known as the SpiderMonkey (sounds really weird to someone from the animal kingdom). SpiderMonkey was the first ever JavaScript engine created for the Netscape browser. Here’s what Mozilla has to say:

TraceMonkey adds native‐code compilation to Mozilla’s JavaScript engine (known as “SpiderMonkey”). It is based on a technique developed at UC Irvine called “trace trees”, and building on code and ideas shared with the Tamarin Tracing project. The net result is a massive speed increase both in the browser chrome and Web‐page content.

Bunch of OOP Tutorials

June 13, 2009

Lesson: Object-Oriented Programming Concepts by Java

Basically it’s an introduction to Object-Oriented Programming written by Java experts. It’s a delight for programmers though since the tutorials mainly focus on the concept of the OO Programming rather than specific language syntax. Covers most of the topics in OOP including interfaces.

The Object Oriented Programming Web

I guess the site can describe itself better than I can:

The Object Oriented Programming Web publishes FREE programming and computer science tutorials, lecture notes, course slides and e-books. OOPWeb.com is a great resource for all programmers and computer science students, but it’s especially popular among those who are interested in C++, Java and Object Oriented Programming.

And damn, it has some of the nicest collections of algorithms, ranging from graph theory to Sorting and Searching algorithms

Object Oriented Programming in JavaScript by Mike Koss

I know it’s not a language independent tutorial but it is really, really an excellent tutorial. And besides, most of the web designers and programmers need to know JavaScript, the so-called “behavioural” language of the web. HIGHLY RECOMMENDED.

JavaScript Object-Oriented Programming

This is an article from SitePoint, so we can expect it to be really good. And it is. I am not much of a hard-core programmer but I can say that it’s a bit technical and as the name suggests, the article is language specific. But then again, everybody developing the web needs to know JavaScript by heart.

Object-Oriented Programming Concept

The tutorial is relatively short and can be skimmed pretty quickly (hey! that’s a plus point for us lazy coders). Mainly deals with the different types of relations between objects, their lifestyles and soap operas (okay, cancel the last one). Has some neat and easy-to-understand examples (cars and pizzas).

OOPS Concepts

This article from Exforsys Inc. is what you really want. It’s language independent and although sometimes it bends towards technical terms, it is relatively easy to understand. P.S. I first thought the site name was Exorcist (dyslexic? hmm).

What is Object Oriented Programming (OOP)? by Tony Marston

I don’t know about you but I really liked Tony’s series of articles about Object-Oriented Programming. It’s really meant to be Newbie-Object-Oriented-Programming (NOOP? I thought it would be noob). The author puts some really neat examples to make sure that everyone can understand the basic concept of Object-Oriented Programming.

Object Oriented Programming with PHP by Kevin Waterson

I know some guys get upset seeing the wealth of information scattered around the web but none of them giving suitable explanations. Well, Kevin is one of them then. This guy probably packed a whole book into one complete page explaining all the important concepts of OOP and also for us lucky web developers, he has written the article using PHP! He discusses advanced topics like Autoload, Overloading, and Class Constants. MUST READ.

OO PHP Part 1: OOP in Full Effect

And boy didn’t we see the effect in full or what? This article is a whopping huge post of detailed information about the PHP OOP features. Yes sirree it is not language dependent article but WTH (notice: I didn’t use WTF…I think I just did). So get some cups of 100% caffeinated coffee and start gaining vital knowledge about OOP.

I saw this site while I was in the hunt for creating a live AJAX page. That is, a page where it gets updated “asynchronously” by user data. The site has different workshops for AJAX applications and I found what I was looking for. Click here to see the tutorial.

Other than that, it lists many interesting tutorials including Max Kiesler’s collection of AJAX tutorials.

Using JSON with JavaScript

May 30, 2009

Source: http://blog.platinumsolutions.com/node/91

JSON (JavaScript Object Notation) is a light weight data interchange format alternative to using xml with Ajax. It is a subset of the JavaScript object literal notation that which is basically made of 2 object types. The first being a collection of name value pairs similar to a hash table. An ordered list of values is the other, basically representing an array.

  1. jQuery pageSlide: jQuery pageSlide is a plugin for jQuery that slides the viewable webpage off-screen, revealing and populating a secondary interaction pane. It may be used in a similar manner to Lightbox, where screen real estate and centralization of the user experience are a concern.
  2. Create a simple ul list with a nice slide-out effect for li elements: We want to obtain this effect: when an user clicks on a link (”Hide”), the related
    element disappear with a nice animated slide out effect. A simple way to implement an animated “disappear” effect using MooTools slideOut()
  3. Portfolio Layout Idea Using jQuery: Benjamin Sterling created an interesting portfolio layout and added a nice easing method to the main content panel using easeOutQuad and easeInQuad using jQuery easing plugin.
  4. Creating a Slick Auto-Playing Featured Content Slider: Niall Doherty’s Coda Slider inspired lot of designers and got them started quickly designing around it. Chris Coyier created a Slick Auto-Playing Featured Content Slider using Coda Slider plugin pretty much “out of the box” and added to it.
  5. Easy Image or Content Slider: Easy Slider enables images or any content to slide horizontally or vertically on click. It is configurable with css alone.
  6. mooSlide: mooSlide is nice replacement of the common “lightbox” module. It has some interesting options to influence the look and behaviour of the sliding box.
  7. jQuery.SerialScroll: jQuery.SerialScroll allows you to easily animate any series of elements, by sequentially scrolling them.
  8. Agile Carousel: Agile Carousel allows you to easily create a custom carousel.
  9. Animated JavaScript Slideshow: This extremely lightweight JavaScript animated slideshow script includes a number of cool features to to style your content: description support, link support, no naming restrictions, portrait image support, graceful degradation and active thumbnail status.
  10. Sexy Lightbox 2: Sexy Lightbox 2 is a sexier and lighter clone of the classic Lightbox. Supports displaying images and HTML elements.
  11. UI.Layout: Was was inspired by the extJS border-layout. The UI.Layout plug-in can create any UI look you want – from simple headers or sidebars, to a complex application with toolbars, menus, help-panels, status bars, sub-forms, etc.
