  A JS1K competition demo for 2012

JS1K is a website which hosts some competitions to attract geeks from the world to create  JS apps which are less than 1K (1024 bytes). The object of this competition is to create a cool JavaScript "application" no larger than 1k. Starting out as a joke, the first version ended with a serious amount of submissions, prizes and quality.Recently, I revised a previous project of mine and compressed it to 1018 bytes and submitted it. It is an analog clock. The code is shown below:w=c.width;h=c...

  Three ways to define class in JavaScript

In object oriented programming, class is the template of object, it defines the properties and methods of a group of objects. Unfortunately, JavaScript doesn't support class, but we can have some workarounds to simulate class.1. Constructor functionThis is the classical approach, it is also the approach mentioned in many text books. It uses the constructor function to simulate class and it uses the keyword this to represent the object internally.function Cat() {　　this.name = "Kelly...

  Algorithm : Delete middle node from singly linked list

Questions about singly linked list are frequently asked during technical interviews. Today we will share with you one algorithm question about singly linked list. Here is the problem description. Assuming the only information you are giving is there is a pointer to a middle node of a singly linked list, no other information about the linked list is given. Please delete this node and don't affect the structure of the linked list. Initially you may think this question is easy if you know the hea...

  Ajax file upload tutorial

Step 1 - AJAX file uploadAJAX file upload tutorialFirst of all I have to say that to create a pure AJAX file upload system is not possible because of security limitations of JavaScript. All of the Ajax upload systems I know use some third party tool/package or only mimics the AJAX feeling. Even so it makes file upload process a bit nicer. In the next section I will present you a solution which imitates the AJAX process, but uses a normal upload process and iFrames.The concept: Create a simp...

  9 reasons to use Zsh

Like majority *nix users, I have been using bash for many years. Sometimes I feel uncomfortable with bash. I tried use some other shells as well such as ksh, tcsh and zsh which I am going to talk about. A few days ago, I found an open source project ranking in the 6th named oh-my-zsh on Github, I downloaded it and had a try with it. It's amazing. We should use zsh to replace bash now. Why do we need to use zsh? Here is a 4 minutes YouTube video which shows many reasons why we should switch from ...

  32-bit vs 64-bit

I have knowledge on 32-bit vs 64-bit, but not very clear minded. Here is a good article I found about it. http://www.techsupportalert.com/content/32-bit-and-64-bit-explained.htm   Understand there are 3 things involved: CPU, OS and application. To work on 64-bit, first thing first is: you need a 64-bit CPU. 64-bit CPU usually provide emulation for 32-bit system. Though some 32-bit application still cannot run on 64-bit OS, because they might contain 16-bit code. 32-bit system won't have com...

  Chrome is dominating the browser world

Microsoft has announced recently that their Edge browser will abandon its own kernel and switch to use Google Chromium. This by no means indicates that Microsoft admitted it lost the war against Google on browser. For Microsoft, making such a decision is certainly not easy, but it is absolutely a wise decision. After all, the market share of both parties are not at the same competing level anymore. According to NetMarketShare's statistics, Chrome's market share in desktop world has reached 67.29...

  Redesigning the Technical Hiring Process

Since my last post on technical interviews, I’ve been fairly involved in hiring at Pulse as we grew our team from 6 people when I joined last November to 14 full-timers. In my previous post, I suggested that technical interviews, in the conventional sense, are not especially effective (by technical interviews, I mean the traditional 45 minute coding-at-a-whiteboard and algorithm puzzlers interviews). Those do a great job of telling you how well a candidate is at acing those types o...
