Google's acquisition of Quickoffice threatens Microsoft
Windows has over 90% market share in desktop operating systems, even though now other OS such as Mac OS and Linux are saying they are more user friendly, more stable and safer than Windows, Windows still has a weapon MS Office which can defeat all of them. However, with the development of mobile network and cloud computing, Windows is now challenged by different competitors on mobile and cloud areas. Mobile and cloud are weak sides of Microsoft , but they are strength of Google.Google sudd...

JavaScript tips both novice and veteran developers can benefit from
In this post, we will share some less known but powerful JavaScript tips which can benefit both novice and veteran JavaScript developers. 1. Truncate array with array length We all know that object are passed by reference in JavaScript, but we may be bitten by this rule. Please check below example: var arr1 = arr2 = [1, 2, 3]; //Change arr1 arr1 = []; // arr2 will still be [1,2,3] arr1 and arr2 point to the same array [1,2,3] initially, later when arr1 repoints to [], the reference to arr2 is n...

25 worst passwords in 2012
Weak password is a serious security vulnerability, but the majority of network users still use some universal simple character sequences as the password. SplashData recently announced the world's worst password list in 2012. "password","123456" and "12345678" are still at top places, while others have varying, some new passwords like "welcome" "Jesus" "ninja","mustang"and "password1 "are in the list. With the risk of password loss, SplashData CEO Morgan Slain said we hoped netw...
Why cannot compare double values directly for equality?
A question in PHP: Get some value from the database and use floatval() to convert it to floatint point value, then compare it with another value which is also converted to floating point value with floatval(). These two values are the same when using var_dump() to output, the two outputs are float(8.87), they are the same. But when comparing them for equality, the result is weird., they are not equal. Why?To analyze this question, we need to start with PHP data types. PHP uses weak types. In PHP...

Understanding Slice Behavior in Go
In Go, understanding how slices behave when passed to functions is crucial for writing efficient and bug-free code. This behavior is often a source of confusion for many developers, especially those new to the language. In this article, we'll explore the difference between passing slices by value and by reference, and how it impacts the modification of slices within functions. Introduction In Go, slices are a fundamental data structure used to work with sequences of elements. They are essentiall...

Three images to understand immutability of String in Java
String is immutable in Java. This means once a String object is created and instantiated, that object cannot be changed. Any operation on the String object will create a new Object instead of operating on the original content. Below are three images to help you understand String immutability in Java. Declare a String String s = "abcd"; s stores the reference to the string content created in the heap. Assign the String reference to another String variable String s2 = s; s2 stores the same ...
JavaScript: Passing by Value or by Reference
In JavaScript, we have functions and we have arguments that we pass into those functions. But how JavaScript handles what you’re passing in is not always clear. When you start getting into object-oriented development, you may find yourself perplexed over why you have access to values sometimes but not other times. When passing in a primitive type variable like a string or a number, the value is passed in by value. This means that any changes to that variable while in the function are com...

Google+ is sick
Google says that Google+ now has over 170million registered users, but according a new research report of Fast Company about Google+, Google+ is just a virtual ghost town.This research selected a sample of 40,000 random Google+ users. The result is :The average post on Google+ has less than one +1, less than one reply, and less than one re-shareRoughly 30% of users who make a public post never make a second oneEven after making five public posts, there is a 15% chance that a user will not ...
Why I Use Vim
I've been using MacVIM as my editor of choice for a couple of years now, yet in many ways I still feel like a beginner. Every day I am learning more and more about my editor, but it takes a conscious effort to become proficient with an editor like Vim. Here's why I make that effort. Editors are something that are very personal; they have to fit with your own work flow approach to programming. If you have ever stopped to think about it, the way each person goes about editing text is quite differe...
HeartBleed: OpenBSD now starts to clean up OpenSSL
Since the disclosure of HeartBleed bug in OpenSSL, some arguments emerge around the safety of OpenSSL, the largest open source SSL/TLS library used by large number of servers, applications. Some people are even starting to create their own version of SSL library. This includes OpenBSD, a famous Unix like open source operating system. Just a few days after the HeartBleed bug, OpenBSD forked a new branch of OpenSSL and started to clean up the forked branch and plans to merge it to its own cod...
