  The Essence of Google Dart: Building Applications, Snapshots, Isolates

WÑ–th thousands of programming languages floating around, why is Google introducing Google Dart? What can it possibly add? The short answer: the Google Dart team wanted a language well suited to modern application development, both on the server and the (mobile) client. Some of Dart's features address problems that languages like Java or Javascript have long had. Dart's Snapshots resemble Smalltalk images, allowing (nearly) instant application startup and wi...

  What is goroutine?

Casual Talk Golang is quite enjoyable to write, aside from the tedious if err != nil checks. One of the fundamental reasons for the joy is goroutine, a core feature of Golang. Understanding goroutines in detail is worthwhile, as they contribute significantly to the pleasure of working with Golang. So, let's talk about goroutines, hoping to provide some insights to the readers. TL;DR: We'll start by talking about assembling a computer, then delve into some concepts of the operating system, such ...

  Understanding PHP's internal function definitions

Welcome to the second part of the “PHP’s Source Code For PHP Developers” series. In the previous part ircmaxell explained where you can find the PHP source code and how it is basically structured and also gave a small introduction to C (as that’s the language PHP is written in). If you missed that post, you probably should read it before starting with this one. What we’ll cover in this article is locating the definitions of internal functions in t...

  Please Steal These webOS Features

When Apple introduced the first iPad in 2010, I bought one immediately. I didn’t know what I’d use it for, but I was sure that I would find some use for it. I never did. I played around with it, wrote some code for it, but eventually stopped using it. I would pick it up from time to time to read something or watch a YouTube movie, but even that was a rare occurrence. I have since picked up an iPad 2, and I’m using it a lot more than the first iPad, but again, I’...

  True Scala complexity

Update 2: Sorry for the downtime. Leave it to the distributed systems guy to make his blog unavailable. Nginx saves the day.It’s always frustrating reading rants about Scala because they never articulate the actual complexities in the core language.Understandable—this post is intended fill that gap, and it wasn’t exactly easy to put together. But there’s been so much resistance to the very thought that the complexity exists at all, even from on up high, that I thou...

  Tricks with Direct Memory Access in Java

Java was initially designed as a safe managed environment. Nevertheless, Java HotSpot VM contains a “backdoor” that provides a number of low-level operations to manipulate memory and threads directly. This backdoor – sun.misc.Unsafe â€“ is widely used by JDK itself in packages like java.nio or java.util.concurrent. It is hard to imagine a Java developer that uses this backdoor in any regular development because this API is extremely dangerous...

  What do programmers really do?

Computers are useless. They can only give you answers. â€“ PicassoMany people (including my mother-in-law) think that computers are becoming so smart that programmers will be no longer needed in the near future. Other people think that programmers are geniuses who constantly solve sophisticated math puzzles in front of their monitors. Even many programmers don’t have clear idea what they do.In this post I want to provide some explanation to uninformed people what programmers rea...

  Oracle CEO Mark Hurd : IBM PureSystem is far behind Oracle

Oracle CEO Mark Hurd had an interview with Chinese media in San Francisco on 19th April. Mark Hurd first introduced different levels of Oracle's overall strategy: 1) the product must achieve best among similar products; 2) system open, vertical integration to provide customers with maximum performance; 3) Industry specific solutions; 4) give users the right to choose and the integration of the cloud environment (private cloud, public cloud, mixed cloud). In addition, Mark Hurd share his own...

  The trap of the performance sweet spot

This post is about JavaScript performance but I would like to start it by telling a story that might seem unrelated to JS. Please bear with me if you don’t like C.A story of a C programmer writing JavaScriptMr. C. is a C programmer as you can probably guess from his name. Today he was asked by his boss to write a very simple function: given an array of numbered 2d points calculate vector sum of all even numbered points... He opens his favorite text editor and quickly types somet...

  Python object creation sequence

[The Python version described in this article is 3.x] This article aims to explore the process of creating new objects in Python. As I explained in a previous article, object creation is just a special case of calling a callable. Consider this Python code: class Joe: pass j = Joe() What happens when j = Joe() is executed? Python sees it as a call to the callable Joe, and routes it to the internal function PyObject_Call, with Joe passed as the first argument. PyObject_Call looks at the ty...
