The significance of this is Elon Musk, who is the self-driving Uber of dot.com billionaires and is the hero of our times.
Well, I knew Steve Jobs well enough, and have met a few civilian astronauts and a bunch of other rich people. None of the others seem to have done so much for the long-term future of the human race as Musk has in leading the path to more affordable spaceflight.
Also a lot of engineers that you can fire or layoff without causing shareholders to notice.
I don't know how good Dyson is good with HR. But those comments make it sound like it may be a tough job to keep.
That and they have less to loose in case of failure. So they are willing to take more risks and perhaps get bigger rewards. Having a family while personally rewarding forced you to play it safer as failure will effect more than themselves.
And how would they check that? Sure they can filter IPSEC traffic but there are many more VPN types, over HTTP, SOCKS, SSL and quite a few 'experimental' ones (encapsulated in DNS or ICMP).
Criminal investigations don't use 'undelete'. They use electron microscopes to read areas that were microscopically out of alignment the next time the drive passed it's head. It's very expensive to actually recover large amounts of data this way, but for 'spy agency' needs it's trivial.
That is not how FBI investigations work. You can't just turn over the data, there is a chain of evidence.
This isn't about proper disposal. The e-mails were destroyed after the server had gone offline and the inquiry had started. She was ORDERED to turn the drives over, instead she wiped the drives and then turned them over.
Per definition her e-mail was public record and should've been turned over to the proper archivists, they have the job of filtering out private e-mails (if any). She knew about it and when the investigation started, she destroyed the evidence. You don't use BleachBit on a live Windows server, if you've ever worked with Exchange, all e-mails are stored in binary blobs. You can't destroy 'just the bad', you have to destroy the entire system.
Dead? No excuse for laying off work.
