  Preprocessor magic:Default Arguments in C

This post is for programmers who like C or for one reason or another can't use anything else but C in one of their projects. The advantages of having default arguments is not something that needs convincing. It's just very nice and convenient to have them. C++ offers the ability to define them but C under the C99 standard has no way to allow it. In this post I will detail two ways I know of implementing default arguments in C. If a reader happens to know additional ways please share in ...

  JavaScript cross domain request solution

1. What is cross domain? We may often using AJAX to request data from other domain, now we will have cross domain request issues. It's because JavaScript only allows to request data from the same domain because of security consideration. In short, same domain strategy means a piece of code can read data from the same source, the same source here means the combination of the same domain, protocol and port number. For example: URLDescriptionAllow communication? http://www.a.com/a.js http:/...

  Create namespace in JavaScript

A namespace (sometimes also called a name scope) is an abstract container or environment created to hold a logical grouping of unique identifiers or symbols (i.e., names). An identifier defined in a namespace is associated only with that namespace. The same identifier can be independently defined in multiple namespaces. That is, the meaning associated with an identifier defined in one namespace may or may not have the same meaning as the same identifier defined in another namespace. Languag...

  Be careful about nil check on interface in GoLang

nil check is frequently seen in GoLang code especially for error check since GoLang's special error handling convention. In most cases, nil check is straight forward, but in interface case, it's a bit different and special care needs to be taken. Take a look at below code snippet and guess what the output will be. package main import ( "bytes" "fmt" "io" ) func check(w io.Writer) { if w != nil { fmt.Println("w is not nil") } fmt.Printf("w is %+v\n", w) } func main() { var b *bytes.B...

  So you want to write JavaScript for a living?

What do you need to know if you are interviewing for a job that involves Javascript development? What kind of expectations do employers have of candidates now that the state of client side development has been changed with the rise of asynchronous JavaScript and the often slick, supporting interfaces? These were questions I was asking myself after a friend pointed me to an interesting job posting over at Meebo that included some JavaScript puzzlers on logical operators, DOM odditi...

  Commonly used AJAX frameworks

This makes our web apps look like desktop applications and bring good user experience to our visitors. You can create an XMLHttpRequest object every time when you want to initialize an AJAX call, unfortunately you may need repeat eve...

  TIOBE : What's the future of C#?

TIOBE released the programming language index for August 2012, the top 3 programming languages are still C, Java and Objective-C. Objective-C still performs well after it ranked 3rd place last month, it's still rising. Is there any possibilty Object-C will overtake Java in the near future?

  STOP WRITING GOOD CODE; START WRITING GOOD SOFTWARE

Good software trumps elaborate code. And unfortunately, you can’t usually have both. The real world has deadlines and ship dates. It’s a game of pick two:Ship on timeShip with elaborate codeShip with a fantastic productAlmost always, you should pick the first and the last when you’re building software applications for users (if you’re building API’s or open source libraries for other developers, then it’s a different story). Too often I have seen de...
