I'm buying a new computer?

I'm buying a new computer. It has an Intel core i7 4770k processer with a speed of 3.5 ghz. 12gb of ram, 2tb hard drive and age force GTX 760 graphics card with 1.5gb of memory. I will be using this for games like skyrim, minecraft, lol, bo2… I also want to use it to browse the Internet, watch vids and do some video editing.

How did Mojang make money?

After people bought the game, they continued to update Minecraft, but if everyone had already bought it, how were they making money off of creating updates that registered users of the game could download for free?

Whenever I craft a computer in Tekkit the game won't give me the item?

I'm just starting off about ten minecraft days in and I have enough resources to make a turtle, but whenever I try to craft a computer, I'll take the computer and try to put it in my inventory but it pops right back. If anyone can help me fix this problem, it would be much appreciated.

Minecraft: Can I have some help on mapmaking?

Ok, if you aren't a mapmaker, you shouldn't answer this question. Because you can't.

Here is the question: I was playing around on a Minecraft world. I was wondering if I could make the player detect a certain player's skull under their feet. I did this:

/testforblock ~0 ~-1 ~0 Minecraft: skull 1 {SkullOwner: Notch}

Sadly, this didn't work. Can you try to answer in the most elaborate way?

How to put Builds Into my Minecraft Game?

Alot of times I would like to builds into my world like to put builds into my world but I don't know how to. I know how to put put previously created maps on my games like The Dropper, of Diversity. I would love to check out this Craftsman Home and check out how to build it but i'm not sure how to put it onto a leval and see. Could you guys help me out guys?

Can you think of any reasonable reasons for this?

I have a 15 y/o severely autistic son in high school. He eats lunch in the resource room and then he just wanders around that room loosely supervised for an hour- he engages in a lot of self-injurious behaviours at that time (gee, I wonder why), so they put a helmet with a visor on him to reduce the impact of the self-harm. Last year I asked if he could join the minecraft club. The club is just a bunch of computer guys playing minecraft in a room. My son likes to play minecraft so that would be perfect for him. The teacher running the club didn't want him there and apparently they're not "legally obligated" to accommodate this, so of course they didn't (not really the "going above and beyond" types I guess). But I just started thinking this year, why can't he play minecraft in resource?

We had a really disappointing IEP meeting yesterday. His teacher is the head of autism education for the entire city, which you'd think would be good. But it's not because she thinks she knows everything there's to know about AUTISM and sees "autisms" rather than INDIVIDUAL HUMANS. Not a good start to the year. Anyway… Big surprise, she doesn't see how this would benefit him- that's the only reason she gave. (Really? You don't see how him not banging his head with helmet on for an hour doesn't benefit him? *resists urge to strangle*).

Anything potentially positive immediately gets shot down with an emphatic NO. Objective people: can you think of a good reason? I'm so disappointed.

Added (1). I have become more of a hell-raiser over the years, but it's not really me. I think it depends on the teacher. Some teachers, if they like you, they will work *with* you, but if they don't (because you went in with guns blazing) they won't (this is always what I hope for). But then other teachers (like this one, it appears), you need to go in with guns blazing to get anything done. I might have to put on my battle armour…
