By default, the main axis runs horizo...

  GCC is compiled with C++ compiler

On 15 Aug, 2012, GCC merged a patch--Merge from cxx-conversion branch . This means GCC will be compiled with C++ compiler in the future, it also means that GCC will be implemented using C++. You may have following two puzzles: Why does GCC turn to C++? Without C++ compiler, how can we compile C++ codes? Why using C++? In GNU's C++ Conversion, we can find this description in the background section: Whether we use C or C++, we need to try to ensure that interfaces are easy to understan...

  Building a Modern Web Stack for the Real-time Web

The web is evolving. After a few years of iteration the WebSockets spec is finally here (RFC 6455), and as of late 2011 both Chrome and Firefox are SPDY capable. These additions are much more than just "enhancing AJAX", as we now have true real-time communication in the browser: stream multiplexing, flow control, framing, and significant latency and performance improvements. Now, we just need to drag our "back office" - our web frontends, app servers, and everything in between into this cen...

  TIOBE : C overtakes Java as the No.1 programming language

TIOBE has released the Programming Community Index for April 2012. The highlight of this month is that C overtakes Java as the No.1 programming language again. C language is liked by more and more developers of all ages. Due to the growing popularity of the Android platform, Java decline will not be obvious. Previously Java took a very long time to overtake C, now C once again returns to the throne. The battle between these two languages will continue.The top three are respectively, C, Jav...

  Some frequently used ES6 code snippets

Below are a list of ES6 code snippets which are used frequently. Hope that it will be helpful. 1. Shuffle array elements let arr = [67, true, false, '55'] arr = arr.sort(() => 0.5 - Math.random()) console.log(arr) // [ '55', 67, false, true ] 2. Remove characters which are not numbers const str = 'xieyezi 23213 is 95994 so hansome 223333' const numbers = str.replace(/\D/g, '') console.log(numbers) // 2321395994223333 3. Reverse sequence or words const sentence = 'xieyezi js so handsome, lol.'...

  PHP function overloading puzzle clearer

PHP's meaning of overloading is different than Java's. In PHP, overloading means that you are able to add object members at runtime, by implementing some of the __magic methods, like __get, __set, __call, __callStatic. You load objects with new members. Overloading in PHP provides means to dynamically "create" properties and methods. These dynamic entities are processed via magic methods one can establish in a class for various action types. Some example:class Foo{    p...

  The "C is Efficient" Language Fallacy

I came across an article yesterday about programming languages, which hit on one of my major peeves, so I can't resist responding. The article is at greythumb.org, and it's called Programmer's rant: what should and should not be added to C/C++. It's a variation on the extremely common belief that C and C++ are the best languages to use when you need code to run fast. They're not. They're good at things that need to get very close to the hardware - not in the efficiency sense, but in the...
