  NIO vs IO in Java

Java 1.4 provides a new API for handling IO -- NIO. This is a non-blocking and buffer oriented IO API. Below are main differences between the NIO and IO in Java. IO NIO Stream oriented Buffer oriented Blocking IO Non-blocking IO N/A Using selector Stream oriented vs Buffer oriented The main difference is that IO is stream oriented where the data is read byte by byte and the data will not be buffered normally.This means there is no pointer to move forward and backward in the stream. I...

  insertAdjacentHTML() Enables Faster HTML Snippet Injection

In Firefox 8, we’ve added support for insertAdjacentHTML(). It’s an ancient feature of Internet Explorer that has recently been formalized in HTML5 and then spun out into the DOM Parsing specification. The bad news is that Firefox is the last major browser to implement this feature. The good news is that since other major browsers implement it already, you can start using it unconditionally as soon as the Firefox 8 update has been rolled out to users.Basic Usage...

  Uber’s audio recording plan in Brazil and Mexico

Uber has recently come out with a plan to introduce a new feature to its App in Brazil and Mexico. The feature will record the conversations between the driver and the passenger, with their consent. But consent here is a bit tricky. Basically, if the driver decides to turn on the recording feature, they are not obligated to warn the passenger and vice versa. Once the recording has been made and submitted to support for some kind of violation, neither of the two parties will have the ability...

  Use of log in programming

Usually, The purposes of log are for troubleshooting and displaying program running status. Good log will help us locate the error easier. Many programmers think log in programs is very simple, but it's not an easy task to write log codes to efficiently locate the error. Here we discuss about program log in three aspects: Where to log What to log Log styles to be avoided Where to log 1.

  Can private method be overridden?

The private methods are not inherited by subclasses and you cannot be overridden by subclasses. According to Java Language Specification (8.4.8.3 Requirements in Overriding and Hiding), "Note that a private method cannot be hidden or overridden in the technical sense of those terms. This means that a subclass can declare a method with the same signature as a private method in one of its superclasses, and there is no requirement that the return type or throws&nb...

  What does super.clone() do?

Object class has a protected clone() method declared to make it possible for all classes make a clone of itself when needed. The clone() is often used when a new instance of the class is needed while at the same time to maintain the same state as the original object. Any class which wants to have clone enabled has to implement the marker interface Cloneable. If a class which implements Cloneable doesn't override the Object.clone() method, the Object.clone() method will be called to just make a b...

  PHP buffer: output_buffering and ob_start

buffer is one piece of memory section, it is usually 4Kb in Linux. It is mainly used between different devices with different speed or different priorities. With buffer, the waiting time between different processes will be reduced. Here is one simple example, when you type something in a text editor, every time when you type a character, the operating system will not write it to the disk directly, instead it will write it to buffer first When the buffer is full, the data in the buffer will be wr...
