Comment: How lethal are GRBs? (Score 4, Interesting) 237

The abstract doesn't say how bad it is to be hit by a GRB beam. GRBs don't last for more than a couple of minutes. It seems that would fry the side of the planet facing the GRB, but the other side would be shielded from much of the radiation. So you zap half the lifeforms and maybe you boil some ocean. No doubt it's unpleasant on the dark side, but is it lethal?

Clearly, you can NAT an entire nation! IT JUST WORKS!

(Of course, the fact that one of the most reclusive and oppressive nations in the world is using this isn't a shining endorsement, but still....)

Sure, but your big NK router only has 64K ports per external IP address. It will probably croak well before it has 64K NAT sessions going, though.

There are at least 2 issues with cloud mail like gmail -- having GBs of mail archive sitting there (the static problem) and you have email coming & going over SMTP (dynamic). Got to deal with both. Unfortunately, you probably do need a first class (authenticated) SMTP relay for reliable outgoing mail. Tanstaafl!

I just replaced my Google Mail account with a Raspberry Pi running Postfix and Dovecot. It does the job, if you don't get more than a few messages per minute. My motivation is to reduce my Internet Data Footprint -- the amount of stuff that is available to Google, NSA, et al to paw through. It uses trivial power, so there's no issue running 24/7. (If you're thinking about this, I'd recommend the BeagleBone Black - a lot faster for $10 more.)

The worst downside (besides having to set up and manage the thing) is spam control. Gmail is excellent at this, and Postfix/Amavis/Spamassassin only catches a fraction of the incoming bad stuff. There are cloud services for spam filtering, but they seem expensive for a single user.

Make sure your code does nothing gracefully.
