  The seven rules of Unobtrusive JavaScript

I've found the following rules over the years developing, teaching and implementing JavaScript in an unobtrusive manner. They have specifically been the outline of a workshop on unobtrusive JavaScript for the Paris Web conference 2007 in Paris, France. I hope that they help you understand a bit why it is a good idea to plan and execute your JavaScript in this way. It has helped me deliver products faster, with much higher quality and a lot easier maintenance. 1. Do no...

  Kicking ass together: How to improve coding skills as a group

Over the last year and a half, I have worked with a small group of students and staff to create an excellent online learning community at Mendicant University. Unfortunately, because Mendicant is something that we’re intentionally scaling at a very slow pace, we won’t directly reach as many people as we’d like to any time soon. In this post, I’ve collected some of the things that I think contribute to making Mendicant University a great place to learn. I’d love...

  Php Class to Retrieve Alexa Rank

Alexa is a service acquired by Amazon which offers a web traffic report for websites. They retrieve the data from toolbar that can be installed in different browsers, centralize the data and display reports to anyone. The most important indicator is the Alexa Rank. It represents the rank of a webpage in a list of all the websites. It’s not the 100% accurate but it gives a good indication.Alexa does not offer any free API to obtain Alexa Rank. However there is a simple method to obtain it ...

  Set Theory in C++11

Have you ever felt the need to perform set theoretic operations on types? Not really? Me neither, but I thought it’s a fun thing to try out. So, if you ever feel the need of using type sets, C++11 makes it quite easy to do so. Especially variadic templates allow for a much more condensed syntax compared to type list constructs formerly used. (Disclaimer: This is rather a proof of concept, but maybe somebody comes up with a useful scenario.) Let’s start by d...

  Prototypes and Inheritance in JavaScript

Forget everything you know about object-oriented programming. Instead, I want you to think about race cars. Yes – race cars. Recently I was watching the 24 Hours of Le Mans –a popular racing event in France. The fastest cars in the race are the Le Mans Prototypes. Although these cars are built by car manufacturers like Audi and Peugeot, they are not cars you’ll see on the streets and highways of your home town. They are built exclusively for high-speed endurance ra...

  JavaScript's Two Zeros

JavaScript has two zeros: -0 and +0. This post explains why that is and where it matters in practice. The signed zero Numbers always need to be encoded to be stored digitally. Why do some encodings have two zeros? As an example, let’s look at encoding integers as 4-digit binary numbers, via the sign-and-magnitude method. There, one uses one bit for the sign (0 if positive, 1 if negative) and the remaining bits for the magnitude (absolute value). Therefore, -2 and +2 are encoded as f...

  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 ...

  SkipList in Go

Algorithmic thinking is the must-have in the coding world, so I have been keeping the routine of algorithm practice every week, consolidating my knowledge of data structures on one hand, and improving my coding skills as well. A difficult one happened to be stuck in my mind- Implement SkipList with Go, which took me quite a weekend. Below is the front-line report of how I finally got the hang of it. First, from its concept. Wiki has explained it well. a skip list is a probab...

  Get vs Post in HTML form

In HTML, one can specify two different submission methods for a form. The method is specified inside a FORM element, using the METHOD attribute. The difference between METHOD="GET" (the default) and METHOD="POST" is primarily defined in terms of form data encoding. The official recommendations say that "GET" should be used if and only if the form processing is idempotent, which typically means a pure query form. Generally it is advisabl...
