Most of author's difficulties simply stemmed from not understanding how modern android works and boots. Easily fixable by reading more about it. And no, nobody hates guys like you. Problem is tha…
comment
I did. You wanted acknowledgement that there are problems for which GC is best solution in C++. I explained why it is never best and likely never anything beyond "barely acceptable".
comment
Because GC wastes cycles on the user's machines instead of just hiring a competent developer who can manage memory properly. As we move to a more mobile world, wasted cycles matter more. So no. W…

I'll take a look.

Time for an HTTPS-over-SMTP RFC? :)

it reads some coproc regs, which are instructions that cannot be reordered. they slow down everything on an OOO core. after that just some bitmasking (not slow)

Rare earth metals dumping caused all US mines to close for decades.

A very valid point, which will sadly be entirely ignored.

WARNING: yes, i am going to be THAT guy... . . . It amazes me that "thousands" of users sending simple messages is considered impressive nowadays on a machine with a xxxxMHz CPU and at least…

Show me a picture on a teardown on ifixit with this in a nexus phone? Or in an iPhone? No? Yeah...

I've opened many phones and have one open in front of me. I have schematics of a few open too. Some have supercaps for RTC. No extra batteries.

citation please (good luck, as this is false)

This is entirely false for most modern phones

Except that will drive away most good engineers. Most good ones I know will refuse to do "take home" problems for interview purposes. I understand them. It is demeaning. When I get offered o…

A noble goal, but good luck doing this with a QCOM kernel :(

You'll never be able to collect phase shift info from such a setup. Not only will each phone's DSP algos delay the data, but the jitter in transmission and reception will just kill any chanc…

My concern is alleviated Thanks!

""Encrypt entire IP packet using peer ABCDEFGH's public key."" Really? 1. RSA & ECC are both too slow for this to be performant 2. Padding??? Certainly you meant "enc…
