jQuery is now the most famous JavaScript library. There are around 57.3% websites in the world using jQuery, i.e, 6 out of 10 websites are using jQuery. If we only consider those websites which use libraries, then the percentage is even higher which is 91.7%. Although jQuery is very popular, its size is still a headache to many websites maintainers. The uncompressed jQuery 2.0 has a size of 235KB, the size is 81KB after optimization.The jQuery 1.8.3 which supports IE 6/7/8 has a uncompressed si...

  Scala Macros

This is the home page of project Kepler, an ongoing effort towards bringing compile-time metaprogramming to Scala. Our flavor of macros is reminiscent of Lisp macros, adapted to incorporate type safety and rich syntax. Unlike infamous C/C++ preprocessor macros, Scala macros: 1) are written in full-fledged Scala, 2) work with expression trees, not with raw strings, 3) cannot change syntax of Scala. You can learn more about our vision of metaprogramming from our talks. We propose to enrich Scala ...

  C++ Without Fear: Functions

A function is a group of related statements that accomplish a specific task. Understanding functions is a crucial step to programming in C++, as Brian Overland explains in this chapter from his book.The most fundamental building block in the programming toolkit is the function—often known as procedure or subroutinein other languages. A function is a group of related statements that accomplish a specific task. Once you define a function, you can execute it whenever you need ...

  Learn from Haskell - Functional, Reusable JavaScript

Learn You a Haskell: For Great Good? For the last couple months I have been learning Haskell. Because there are so many unfamiliar concepts, it feels like learning to program all over again. At i.TV, we write a lot of JavaScript (node.js and front end). While many functional/haskell paradigms don’t translate, there are a few techniques that JS can benefit from. There are Haskell library functions for everything. At first I thought this was just because it was mature, but then I notice...

  12 Things A Programmer Really Needs To Know

How do you answer the question, “what do I need to learn to be a good programmer?” I have written posts trying to answer that question, typically focusing on the languages that you should learn or the algorithms and other techniques you need to know. What about the rest of a programmer’s life? This is a less serious look at the life of a programmer. So, what does a programmer really need to know?Caffeine â€“ You need to find your preferred caffeine delivery system. M...

  An easy way to log client side information to server

JavaScript debug is a very troublesome thing in web application development. Because many web browsers will not notify you if there is any error in the JavaScript codes you write. They just silently fail and block the following codes execution. In order to debug JavaScript codes, we need a good log mechanism which will help us log the error information,, we often need to log errors in JavaScript codes to server for debug purpose in a production web application, What should we do? The first ...

  In-memory key-value store in C, Go and Python

Subtitle: Wow Go’s net library is fast On paternity leave for my second child, I found myself writing an in-memory hashmap (a poor-man’s memcached), in Go, Python and C. I was wondering how hard it would be to replace memcached, if we wanted to do something unusual with our key-value store. I also wanted to compare the languages, and, well, I get bored easily! The code is on github as Key-Value-Polyglot. Each version implements enough of the get and set commands from the mem...

  What does a contemporary web developer need to know?

The early ages of web era mainly consisted of webpages of text and links. At that time,Netscape was the still dominant of web browser market. As a web developer, you could develop web apps(or better to call web pages) easily with knowledge of HTML only. But with the evolution of web, new technologies came out, we can see more robust web apps around us everywhere. Today as a web developer, the ability to run and configure a web server and edit HTML to create some simple web pages has lost almost ...

  One good way to use optional parameter in function

In GoLang, it doesn't support method overloading like in Java, hence sometimes it would be a headache to create functions to construct new structs with different parameters.  Normally, we would construct the new function as below when want to let others create a new struct instance with explicit function call. type Queue struct { Name string } func NewQueue(name string) *Queue { return &Queue{name} } But with the scope and complexity of the struct increases, there might be more prope...
