Anything dealing with multiverse is speculative. Math does not constitute evidence.
By that argument, everything we know about stars, quasars, black holes, and virtually everything else that isn't on our planet and relatively close to the surface is all speculative, too. Nearly everything we know about the stuff not immediately at hand is based on mathematical models, calibrated against "observations" which are often very, very indirect and themselves dependent on many layers of mathematical models derived the same way.
I don't know enough about QM and many worlds theories to know how much really is well-supported, but from what little I've read, the many-worlds hypothesis seems to provide a much better explanation of the spooky action at a distance effects we observe than the alternatives.
I just did some googling and it seems here in the UK a full time gabage collector would make about £12K per year (though it's paid hourly and in practice it may be difficult to find full time work).
I'm just about to start a postdoc position on just under £30K per year.
Any marginal blocks mapped out before you encrypt will remain unencrypted and may be available to a determined attacker. Same goes for hard drives, and SATA secure erase is not provably trustworthy. Always encrypt your storage before you put any data on it. If you do not trust your hardware AES to not be backdoored then use software crypto.
Yes, the safest approach is to enable encryption just after you get the device (after using it for a few minutes to accumulate some randomness in the Linux randomness pool, so you get a good key). If you don't, totally wiping it is more or less impossible, though the odds of anything significant surviving either the normal wipe or the encrypt & wipe (which probably won't actually do any more than the wipe) are pretty small.
Last time I checked the standard Android encryption will not do the sdcard partition (I mean not the physical card, but the partition on the internal flash, usually the biggest chunk of it, like let's say 11 out of 16GB).
I'm pretty sure that's not true, because it would make device encryption pretty much useless. A glance at the code certainly appears to show that it encrypts all volumes, but maybe
I'll also note that none of the devices I have handy (Galaxy Nexus, Nexus 4, Nexus 5, Nexus 7 1st & 2nd gen, Nexus 10, Moto X, Moto RAZR M, Samsung Note 2) even have an
"universe" = everything observable.
But that grammatical rule breaks down if you put the word at the start of a sentence.
If you have a favorite animal, I can rephrase to accommodate.
Probably wouldn't work with my dog, it would just eat the rubber band.
Big fan of Starts with a Bang for many years, I must ask Ethan why cosmologists have ruled out the idea that our universe is the interior of a black hole. Neil deGrasse Tyson claims Einstein's equations can be interpreted to mean there is a different universe inside a black hole but he doesn't elaborate. If anyone else knows of a good reason as to why our universe can't be the interior of a black hole then I'd love to hear it.
It has been my observation that the people who have blistering hatred for Snowden, are the kinds of people who totally embrace jingoism.
But there are also those who don't have a blistering hatred, yet still feel that he broke the law and should be accountable. I find these people to be especially common among those who themselves are or have been under legal and moral obligations to preserve US government secrets and are appalled that Snowden essentially dumped a huge pile of unsifted sensitive data on the Guardian and trusted them to keep it secure and behave responsibly.
These people largely agree with the need to publish some of the data, but find dumping all of it to be criminally irresponsible.
I think there are a lot more people like that than those who have the blistering hatred you mention. FWIW, my own take (as someone who once held a Top Secret clearance) is that Snowden's action was necessary, that it was infeasible for him to properly vet and carefully release the data, that the news agencies have done a good job and been responsible, and that whatever damage it may have done is far more than offset by the good that it has done. So on balance I consider him a hero. But I do know a lot of people whose concern about what he did tips the balance the other way, even though they don't "have blistering hatred".
