Hi there, people, and maybe you weird non-humanoids that are using this. This thread is for posting programming tutorials.
Please specify whether the tutorial is: Video, interactive, or Article form, free or paid (most will be free, undoubtedly), and judge the level - beginner, intermediate, Stencyl creator level.

This is also for sound and art tutorials.
Anyway, I've got lots o them here, and I'll continuously update this thread.
ART http://garmahis.com/tutorials/pixel-art-tutorials/ - 40 pixel art tutorials.
Article http://speckyboy.com/2009/04/28/35-tutorials-to-create-amazing-vector-graphics-using-inkscape/ - 35 vector art tutorials using a free program called Inkscape.
Article Sounds http://www.squidoo.com/how-to-make-8-bit-music - Orandze is a very good composer.
Article http://www.squidoo.com/how-to-write-a-melody - Another tutorial by Orandze. It's about music theory. My head hurts from it, but it's very useful.
Article PROGRAMMING http://codeyear.com/ - This is for web design.
Interactive http://www.cprogramming.com/tutorial.html - This is for C, C++, and Java in the future. I think it's an okay series of tutorials. I found it a little difficult to get through the walls of text, but maybe it's just the unattractive look of the site. They should put a picture of me in as the background.
Article http://omnitericstudios.com/wp/ - These are some nice Actionscript 3 tutorials.
Article http://net.tutsplus.com/category/tutorials/python-tutorials/ - I haven't really done any of this, but it is a series. I have heard they are good. This is for Python 3.2.
Video https://www.cs50.net/resources/ - A lot of college tutorials here for beginning programming.
Article http://channel9.msdn.com/Series/C-Sharp-Fundamentals-Development-for-Absolute-Beginners - A good C# tutorial. C# is for Windows, which makes it nubby, but it's a good language to go onto something more advanced. Also, if you want to use Unity3D, C# will be invaluable, as will javascript(but C# can do more).
Video http://programming-motherfucker.com - A lot of tutorials. Lots of shit involved. I mean, shit is said a lot. You'll see....

Very good though, at least for the quick python tutorials I saw. HOWEVER, this is for python 2, I think 2.7 to be exact. Python 3.2 is the newest version as of now, and though not quite as easy (in my opinion), it can do more.
Article http://www.w3schools.com/ - Site focusing on website design.
Interactive/Article http://unity3d.com/support/resources/tutorials/ - Official Unity3D tutorials. While there are others that I haven't shared, these are probably the best that are not in a book form.
Article http://flashgamedojo.com/ - A tutorial for flixel, which Stencyl uses.
Article ]/b]
http://www.untoldentertainment.com/blog/understanding-classes-in-as3/ - Some tutorials on Actionscript 3 principles.
Article
http://www.khanacademy.org - A site with thousands of lessons and exercises, almost all focusing on math. However, there is a huge science section with at least a few hundred lessons, and a smallish computer programming section consisting of around 24 lessons. There are some python tutorials here, but I don't know if there are any other ones as of now.
All methods
Post your tutorials and I'll update this frequently! I also have a plethora of Unity3D tutorials, but there are so many that I'm not sure if I should post.
