ARM Assembly Language Tutorial

For some reason, I really keen on using assembly language in Raspberry Pi because it's an entirely new machine architecture for me--despite my past effort on GameBoy Advance (GBA) which results only on HelloWorl application ;). So, interest on ARM is back.

I've been reading a couple of ARM assembly language tutorials so far, but I think the best for complete newbie is this one: It centered around "guess what?" GBA. It's one of the best that describes GNU assembler on ARM architecture I think.

Another great ARM assembly tutorial was made by the late Fravia: The images links are broken in that link, so just download the ZIP file and view the article locally. That way, the images links would be fine.

Driver Signing for Windows Vista/7/Server 2008/8 (x86 and x64)

Details about driver signing and signing mechanism for other code running in kernel mode privilege in Windows Vista or newer (both x86 and x64) is in this link:

I observed that x64 versions on Windows have a better kernel mode code authentication enforcement via driver signing compared to the x86 version.
