Today's Question:  What weekend projects have you created?

#### C++, Ruby and CoffeeScript complexity comparison

There are many programming languages around the world, they all designed to help programmer solve some problems, finish some tasks. These languages are often divided into different types, there are structural, object-oriented, functional, scripting languages etc. Some are easy to pick up such as Java, while some are thought to be difficult to learn such as C++. So how do we understand complexities of different programming languages?Many people agree that C++ is very complex languages, it has poi...

#### Binary tree iterator algorithm

Binary tree pre-order,in-order and post-order traversal are basics in algorithm and data structure.And the recursive binary tree traversal is a classical application of recursion. We define a binary tree node as : // C++ struct Node { int value; Node *left; Node *right; } In order binary tree traversal can be: // C++ void inorder_traverse(Node *node) { if (NULL != node->left) { inorder_traverse(node->left); } do_something(node); if (NULL != node->righ...

#### ARE YOU LIKE ME? OR DO YOU HAVE DISCIPLINE?

If you are anything like me, you've started more things than you have finished. We're innately curious about the things around us and inspired when we come across people who have mastered their trade. We see people create cool and beautiful things and think, "Man, that looks easy, if I put in a little time I can do that in no time." What follows is a few days or weeks of focused and dedicated learning. During this time we make some progress, but not much. In fact, the progress that we do ma...

#### Language Complexity?

Some languages are complex, others are simple … right?  C++ versus just about anything else is a good example here.  But, it begs the question: what makes a language complex? So, I’ve just been reading Bruce Eckel’s Artima article on Scala.  It’s actually a nice article, and I enjoyed it.  But, one thing bugged me — and, it’s nicely summarised in this quote: But you can see from the code above that learning Scala should be a lot easier than learning Java! There...

#### Example of less is more

Less is more is a very important design principle. It is as important as the 80:20 principle. It means that which is less complicated is often better understood and more appreciated than what is more complicated; simplicity is preferable to complexity; brevity in communication is more effective than verbosity. Next we will use an animated image to describe what is less is more. The popularity of flat design in web application design also proves the importance of less is more. Many famous compan...

#### AI solves complex biology problem from scratch

An interdisciplinary, interuniversity group of scientists from Vanderbilt, Cornell, and CFD Research Corporation have created an artificial intelligence capable of solving complex scientific problems from scratch. The AI, called ABE (Automated Biology Explorer), “discovered” how glycolysis produces energy in a living cell by looking at a set of data and then squeezing it into a mathematical formula, just like a human biology researcher.ABE is powered by the freeware Eureqa software, and...

#### Simplicity Oriented Programming

After few years on Warsztat (a Polish gamedev site) I’ve noticed an interesting phenomenon. Every now and then there are Compos (programming competitions) organized in two different flavours. Some compos are single-run events that last only few hours, others are long-term (several days/weeks). And as an extra catch, the former are usually restricted to basic APIs (SDL, OpenGL etc) while the latter are free-for-all (all sorts of engines, UDK/Unity allowed). Now, results are somewhat shocking. M...

#### The Day Programmer vs. The Night Programmer

This post is a slightly edited form of an e-mail that I sent around internally last year. But it was suggested to me recently that I post it up to my blog to see what people think – am I right or wrong? Over the years I’ve come to the belief that there are two kinds of programmer in the world, no matter what technology they work with, lets call them:         1. Day Programmers        2. Night Programmers Now – day pr...

#### Is Scala Only for Computer Scientists?

I have experience struggling through these kinds of things andI know enough about the subject that I can understand why they did it that way. But my concern is that this should be an example that a beginner could understand, and they can't. There's too much depth exposed. Here's the example, which is written as a script: import scala.io.Source._ case class Registrant(line: String) { val data = line.split(",") val first = data(0) val last = data(1) val email = data(2) val payment = da...

#### We need a programming language for the rest of us

Recently I took on the enormous task of learning Objective-C from the bottom up and I was struck by something I couldn’t shake: this is too hard. An experienced developer might scoff at me for saying that, but it’s true. I’ll be honest about my education, Calculus II was the most math I ever took, I have an advanced degree from Berkeley in Journalism. I am a proficient HTML/CSS developer and can glue enough javascript together to solve almost any problem that has presented itself. My ...
