  Notes on Programming in C

Introduction       Kernighan and Plauger's The Elements of Programming Style was an important and rightly influential book.  But sometimes I feel its concise rules were taken as a cookbook approach to good style instead of the succinct expression of a philosophy they were meant to be.  If the book claims that variable names should be chosen meaningfully, doesn't it then follow that variables whose names are small essays on their use are even better?  Isn't MaximumV...

  Save QWidget as image

Qt library is an excellent GUI library for C++ programmers developed by Nokia and now is an open source project. Often, we may use QPainter to draw strings, lines or images on a QWidget. We can override the QWidget's paintEvent() method when we want to use QPianter object to draw something on a QWidget. If we want to save the items drawn on QWidget as image for later reference, what can we do? We can save a QWidget as an image. Here is the code for achieving this: QPixmap pixmap(this->size())...

  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.

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 ...

  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’...

Multiply turing machine The fact it took me 20 lines of javascript to implement a nondeterministic turing machine simulatorlast week kept me up at night. All weekend. Too much code for something so simple and I kept having this gut feeling implementing a basic version shouldn’t take more than 140 bytes. Sunday afternoon I sat down for about an ...
