Using HTML5/JavaScript to generate and save a file
I've been fiddling with WebGL lately, and have gotten a Collada reader working. Problem is it's pretty slow (Collada is a very verbose format), so I'm going to start converting files to a easier to use format (probably JSON). I already have the code to parse the file in JavaScript, so I may as well ...
Why don't they teach these things in school? [closed]

Developing GUIs in Python: Tkinter vs PyQt [closed]
...erious, especially as things you learn will translate directly to working with Qt in other languages too if you ever need to, and Qt is probably the best cross-platform interface toolkit available right now.
There are only two real (potential) disadvantages:

Static Block in Java [duplicate]

It's a static initializer. It's executed when the class is loaded (or initialized, to be precise, but you usually don't notice the difference).
It can be thought of as a "class constructor".
Note that there are also instanc...

...valid conversion in the language, or an appropriate constructor that makes it possible. The only time it's a bit risky is when you cast down to an inherited class; you must make sure that the object is actually the descendant that you claim it is, by means external to the language (like a flag in th...
