Comment Re:Why just Gmail? How far do you want to go today (Score 1) 284

Up to recently, SMTP traffic had only opportunistic encryption, ie, was trivially readable by any attacker. But fortunately, most server software gained support for DNSSEC/DANE, which, while not perfect, is _massively_ more secure. Unlike breaching CA-cartel certificates, breaching DANE pretty much requires suborning the TLD the target uses. Thus, as competent admins configure their MXes for DANE, bulk monitoring of email traffic shuts down.

On the other hand, any government with some clout has warrantless access to big email providers. So for now, we need to use small or individual mail servers.

Comment Re:AMD still around? (Score 2) 98

AMD is vital. All recent and semi-recent Intel CPUs include AMT which is a backdoor that can control any aspect of the running system without being detectable in any way by the operating system. It includes a completely separate sub-processor that has full control of the machine while being invisible to the main CPU.

Disregarding science-fiction babble like in this article, the fastest we can get to Proxima Centauri is 80k years assuming no fundamental breakthrough, or 100 years with ultimately advanced technology that's not known to be impossible with our current knowledge of physics.

Writers of such articles tend to forget that every gram of fuel needs to be accelerated by previous stages, and even worse, all the fuel needed for deceleration must be first accelerated all the way then decelerated partway. This puts a hard cap even if you magically got 100% efficiency.

But fortunately, such writers are also forgetting that physics isn't the only technology field that advances. I'd expect that both stopping aging and sentient AI are no more than 100-200 years away. Just don't forget to take playing cards with you to spend time during than 80k years long trip.
