  passing parameters to XMLHttpRequest’s onreadystatechange function

I’ve been smashing my head against this all day – but I finally got something working consistently and reliable, so I better damn well document it. This is as good a place as any, and hopefully it will be useful to others.I needed to make an Ajax call, so I turned to my good friend XMLHttpRequest. One wrinkle was that I needed to pass in a parameter to it… so I tried:var test = "bar"; req = new XMLHttpRequest(); req.open("GET", myURL, true); req.foo = test; req.onreadystatech...

  Macro vs. Micro Optimisation

So there's recently been a bit of hype about another Colebourne article: http://blog.joda.org/2011/11/real-life-scala-feedback-from-yammer.html I'd like to respond to a few points he makes. First - You should evaluate Scala and pay attention to its benefits and flaws before adopting it.  Yes, there are flaws to Scala.   Working at typesafe makes you more aware of some of them.  We're actively working to reduce/minimize/get rid of these.   In my opinion, the negat...

  Web Technologies Need an Owner

Many people seem to assume that the Web will one day become the one and only client computing platform on Earth, therefore it must not be controlled by anyone. This is a dangerous assumption. The HTML, CSS, and JavaScript triumvirate are just another platform, like Windows and Android and iOS, except that unlike those platforms, they do not have an owner to take responsibility for them.The Web has no one who can ensure that the platform acquires cutting edge capabilities in a timely manner (came...

  Find max subarray of an array

In computer science, the maximum subarray problem is the task of finding the contiguous subarray within a one-dimensional array of numbers (containing at least one positive number) which has the largest sum. For example, for the sequence of values −2, 1, −3, 4, −1, 2, 1, −5, 4; the contiguous subarray with the largest sum is 4, −1, 2, 1, with sum 6. The problem was first posed by Ulf Grenander of Brown University in 1977,...

  What to Look for in PHP 5.4.0

  Best “must know” open sources to build the new Web

Here the dump of my ultimate collection of online Web development resources and directory, oriented for the Front-End user Interface (UI).

Now, as Web Developers and Designers, we have to build on top of more stable framework. It’s her...

  Image lazy loading plugins on Github

Image lazy loading is a concept where images are getting loaded only when needed. It has been adopted in many web applications to reduce usage of bandwidth. When a web page is loaded in a web browser, not all the page elements would be visible in the view port, hence those resources(images, videos etc) don't need to be loaded.  Currently there are quite a few open source plugins on Github which can help achieve image lazy loading. Today we will introduce a few of them. Echo.js Echo.js is a ...
