Does anyone have a minecraft world with a wall?

So I wanted to remake the Ultra Hardcore series that Ethos and Sethbling and them are making with my friends. I wanted to get a world that is perfectly normal, but about 1000-2000 blocks from the spawn is a bedrock wall. Anyone know of anything like this?

How to update Minecraft versions?

Please Note: I have VERY limited development skills, so please speak English.

My son plays Minecraft, and I bought the PC version a year ago or so. It is version 1.3.7, and I've tried many times to do the update to the latest version (1.7.4). It will allow him to launch it and play it, but when he closes it out and attempts to play later, it only goes to the 1.3.7 version.

How do I update the version so that it defaults to the newer version? Again, I apologize for my limited skills in code, etc.

MacBook Pro battery exploded?

I have a 17'' MacBook Pro Late 2006 model i know its pretty old but i got in the box brand new like a year ago free from a friend that never used it because they had a 12 core mac pro. Today i was downloading the 10.7 Lion update then out of no were i heard a POP and i saw the laptop jump a little when i looked at the battery it was all swollen. I'm just asking but shouldn't apple be held responsible for this did they do a recall because this is unacceptable and dangerous do you think i could get a free battery replacement.

And to all the people that say just buy a new one its an old laptop anyways well it does what I need it to do which is web browsing email Microsoft Word and Minecraft normal settings at 60fps so i don't see the need in upgrading.

Can i access my minecraft account on another computer?

I have a minecraft account, and downloaded the game in my current computer. I have been playing my minecraft under the same computer ever since i got the game. However in a few days i'm getting a new computer, and i would really like to be able to access my current minecraft account on that computer when i get it. I know i have to re-download the game on the new computer when i get it, but does that mean i have to make a new account as well? I'm new to this, i do not know much, i'm sorry of this question may sound "dumb" in any way. Also i have a few minecraft worlds. When i get a new computer, and if i'm able to access my old account, will i be able to play in the worlds that i already made? Or do i have to start over?

What programming language should i use to make a game?

I'm trying to make a game sort of like minecraft or terraria. Or even a basic super mario bros game. But basically, i need a programming language that is supportive of 2d and 3d development. I'm willing to learn anything, just give me an idea of what language to do?

Why is my minecraft running so slow?

I recently bought minecraft for my laptop running windows 7. It runs very slowly and laggy to the point where it hurts my eyes to even watch it. I changed the settings to turn off clouds, reduce FPS, fast graphics (not fancy), turned off textures and turned down some other settings. I have even given minecraft high priority use of RAM. My laptop is a year and a half old with a second generation i5 processor, 6 GB of RAM and I make sure I have no other programs running. It is a Dell inpspiron.

Any idea of why this runs so awful? Think it would run better on my MacBook Pro? How can I speed this up?
