The NEON registers are 128-bits wide and there are 32 of them. If you have 32 bit data, you can process 128 chunks at a time!

I don't think you understand how SIMD is used. NEON instructions only apply to 1 register, so it only processes 4x 32 bit at a time.

Actually since 4.8, the correct optimization level to use for debugging is now -Og

From the documentation at http://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html

-Og Optimize debugging experience. -Og enables optimizations that do not interfere with debugging. It should be the optimization level of choice for the standard edit-compile-debug cycle, offering a reasonable level of optimization while maintaining fast compilation and a good debugging experience.

Missing from the summary, of course, is that the family had a son who has actually clicked on a link to an artlcle on how to make a pressure cooker bomb.
"But my son’s reading habits combined with my search for a pressure cooker and my husband’s search for a backpack set off an alarm of sorts at the joint terrorism task force headquarters."

Google may not have been involved at all here. All the investigators needed were the logs for the website hosting the offending article, and a cooperating ISP, to find that family.

In short, he found prior art and submitted it, and the USPTO examiner rejected the patent because of it. From TFA :- "Micah showed me a document from the USPTO confirming that they had rejected the patent application, and the rejection relied very heavily on the document I found. This was, in fact, the first 'confirmed kill' of Ask Patents, and it was really surprisingly easy. I didn't have to do the hard work of studying everything in the patent application and carefully proving that it was all prior art: the examiner did that for me." This is all under the umbrella of Ask Patents'."

I hate DRM like everyone here, but I would rather have the choice to purchase DRMed content than to be completely locked out just because I am not on the 'preferred platform'.

Hopefully DRM will die a natural death from people voting with their wallets when there are alternatives. In that case the act of having HTML5 DRM just gives DRM more rope to hang itself with.

Most Android applications are written in Java, and compiled to be run on the Dalvik VM for which there are implementations for both ARM and Intel CPUs.
Now, many Android applications use the NDK that compiles to native code, but the NDK itself gives you the choice of compiling for ARMv5, ARMv7, x86 and MIPS targets, so providing support for x86 is as simple as adding a line into Application.mk
