NIO vs 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.

Also in the official documentation of PHP regarding the Abstract class and Interface, people are arguing about this. To understand this question, their dif...

How I Develop Things and Why
I've always considered myself a bit of a software junkie. Nothing excites me more than a great piece of new software. Some of my best childhood memories are our trips to Grandma's house, where I'd have access to a computer with a dial-up connection that I'd use to obtain freeware and shareware. I'd bring 4 or 5 floppies with me and try to cram all the games, waveform editors, and utilities that I could sneaker-net home. Luckily today, excellent software written with passion oozes out of ...

Want to be a software engineer? Go to university
This editorial was originally submitted to the Sydney Morning Herald in response to an editorial proclaiming that people wanting to become software engineers should not attend university and instead learn a current popular programming language. Over the past few years I’ve developed software for large corporations, started the Vodafail campaign, co-founded Mijura and represented Australia in the global Robocup (humanoid robotic soccer) competition. I graduated from University...

Apparently,the foreigner cannot buy ticket because he doesn’t have Chinese ID but there still presents an English interface for foreigners on the vending machine. Because of my profession, I find this awkward situation w...

Python threads: communication and stopping
A very common doubt developers new to Python have is how to use its threads correctly. Specifically, a large amount of questions on StackOverflow show that people struggle most with two aspects: How to stop / kill a threadHow to safely pass data to a thread and back I already have a blog post touching on these issues right here, but I feel it’s too task-specific for sockets, and a more basic and general post would be appropriate. I assume the reader has a basic familiarity with Pytho...
