Thoughts on Python 3
I spent the last couple of days thinking about Python 3's current state a lot. While it might not appear to be the case, I do love Python as a language and especially the direction it's heading in. Python has been not only part of my life for the last couple of five years, it has been the largest part by far. Let there be a warning upfront: this is a very personal post. I counted a hundred instances of a certain capital letter in this text. That's because I am very grateful for all the opport...

Developing Game Audio with the Web Audio API
Caution: This article discusses APIs that are not yet fully standardized and still in flux. Be cautious when using experimental APIs in your own projects. Introduction Audio is a huge part of what makes multimedia experiences so compelling. If you've ever tried watching a movie with the sound off, you've probably noticed this. Games are no exception! My fondest video game memories are of the music and sound effects. Now, in many cases nearly two decades after playing my favorites, I still c...

Signs that you're a bad programmer
1. Inability to reason about codeReasoning about code means being able to follow the execution path ("running the program in your head") while knowing what the goal of the code is.SymptomsThe presence of "voodoo code", or code that has no effect on the goal of the program but is diligently maintained anyway (such as initializing variables that are never used, calling functions that are irrelevant to the goal, producing output that is not used, etc.)Executing idempotent functions multiple times (...

32-bit vs 64-bit
I have knowledge on 32-bit vs 64-bit, but not very clear minded. Here is a good article I found about it. http://www.techsupportalert.com/content/32-bit-and-64-bit-explained.htm Understand there are 3 things involved: CPU, OS and application. To work on 64-bit, first thing first is: you need a 64-bit CPU. 64-bit CPU usually provide emulation for 32-bit system. Though some 32-bit application still cannot run on 64-bit OS, because they might contain 16-bit code. 32-bit system won't have com...

Polymorphism in OOP programming
Polymorphism is the capability of an action or method to do different things based on the object that it is acting upon. This is the third basic principle of object oriented programming. Overloading, overriding and dynamic method binding are three types of polymorphism. Overloaded methods are methods with the same name signature but either a different number of parameters or different types in the parameter list. For example 'spinning' a num...

trim() in JavaScript
In the past, JavaScript didn't define the trim() function for String object. This makes web programmers frustrated since they often need to implement this function themselves if they want to handle user inputs. The new version of ECMA-262 introduces the trim() function.15.5.4.20 String.prototype.trim ( ) The following steps are taken: 1. Call CheckObjectCoercible passing the this value as its argument. 2. Let S...

Difference between sans-serif and serif font
When we design website, we will often need to choose which font to use while displaying contents on the page. Basically what's the criteria for the choice? There are two big families of fonts : sans-serif and serif. We need to first understand what the difference is between these two. The word sans is from French, the meaning of it is without. So the difference between sans-serif and serif is serif font will have lines in all ends of the character while sans-serif fonts don't have. Some examples...

A Tiny MySQL++ Tutorial; C++ and MySQL; MySQL++ Example
I wrote a post about how to install MySQL++ and I thought I will write a quick tutorial on how to use it too. This is a very basic MySQL++ program and it’s very self explanatory: #include <mysql++.h> #include <stdlib.h> using namespace std; using namespace mysqlpp; int main() { try { Connection conn(false); conn.connect("DB NAME", "DB HOST probably localhost", "DB USER", "DB PASS"); Query query = conn.query(); } catch (BadQuery er...
